Principle of operation

The system comprises separate functions for A: showing drilling angles and B: showing length measurement. 4.1

Drilling angles definition

The drilling angles system comprises: Transducer to measure the swing movement of the boom versus the carrier. (boom joint transducer). Transducer to measure the angles of the feed beam in X- and Y direction. (angle transducer). Transducer to measure the decided aiming direction (sight) versus the carrier. Indicator with two displays, showing the angles. (indicator) Signal cables for connecting the transducers to the central unit and the indicator. All angles are calculated against the aiming direction.

This means that if the boom and the sight point straight forward, the angles are shown according to fig 3A.

12

4:2 Drilling signal for controlling the length measurement.

Input signals, used for controlling the length measurement are connected to “Upper drill support guide open” and “Unthreading” “Unthreading” of the adapter (Drilling signal 1 and 2). When the switch “Length measurement” is ON the system begins to show position of the drill bit. In length measurement mode the systems holds a steady check of the drill bit. If the drill bit is moving backwards, backwards, the system begins to count down the position of the drill bit. When the signal “Unthreading” “Unthreading” is activated, length measurement measurement is turned off, and the system goes into angle measurement mode.. When the signal “Upper drill steel support open” is activated the length measurement is resumed. When the hole is finished, the length measurement is set to zero when the switch “length measurement” is switch to OFF. Note that the system is measuring the length between the signal “Upper drill steel support open” and the signal “Unthreading”. So this signals must be active at the beginning and the end of the rod.

13

4:3 Laser

The laser sends out a laser beam which rotates horizontally. When the laser is set up, it’s i t’s very simply to adjust, to give an exact horizontal plane. This plane can be used as a reference to height measurement. The laser is set up at a known height from the bottom. See fig 4

Hole length from a laser plane On the cradle there is a sensor which signals to the

Return oil and oil cooler The Hydraulic oil tank has a capacity of 260 litres which means that there is always a “ stock” of oil in the tank. In addition to storage it serves to separate water and dirt. T here are two holders with 3 filters in each which filters hydraulic oil from the return- and drain circuit and the oil during filli ng. There is also a ventilation filter which prevents contaminated air from entering the tank when the hydraulic oil level is changed. Thermostats ensure that the oil flows through the oil cooler when the temperature is above 40ºC and directly to the tank when the temperature is below 40ºC. T he by-pass valve protects the oil cooler from exposing to high pressure. The oil cooler cools the hydraulic oil so that the rig can work at full load in ambient temperatures up to 50°C. The cooling fan is driven by a hydraulic motor that is supplied with oil from pump 4 at a maximum pressure of 160 bars (D5) or 220 bar (D7). T- Return oil is oil is a collection block that collects return oil from the various circuits and leads it t o the thermostats and to the return oil filter. D-Drain oil is oil is a collection block that collects oil from the various circuits and leads directly to the return oil filter.

Engine speed The engine speed can be de- or increased by flicking switch S189 upor downwards. By flicking the switch different times, this puts the N189 connections (Din0-2) in different set of combinations, hence providing the different engine revolutions, and this is controlled by the PLC output Y35-Y37 respectively. PLC can support 8 engine revolutions, and it can store 3 separate engine speeds, one for tramming, one for rod handling and one for drilling. The PLC remembers the engine speeds for rod handling and drilling even when the battery switch is turned off. In tramming mode the system will always start on 1200 rpm.

Compressor

Compressor General The built-in compressor is a single-stage compressor. Its normal working pressure is 10.5 bar with the Caterpillar diesel engine.

Compressor unit The compressor unit comprises two rotors: a drive rotor and a slide rotor mounted on rollers and ball bearings. The drive rotor is driven by the diesel engine and transfers power to the slide rotor. The rotors are lubricated with oil that is injected a nd mixed with the air. This increases efficiency since the oil forms a seal between the rotor blade and the housing. The compressor unit is an Atlas Copco type G106 screw compressor. The gear ration is 1.55.

Air flow The intake air is drawn through the air filter a nd an over centre valve to the compressor unit. The over centre valve also prevents oil returning into the system. The air is mixed with injected oil a nd goes directly from the compressor to the air receiver. In the air receiver, the majority of the oil is separated from the air/oil mixture using an oil separator. This oil is removed by a separator unit. The flow of compressed air passes through a pressure valve to t he drill rigs air system. system. The pressure valve prevents pr events the pressure in the air receiver dropping below the lowest working pressure for the compressor (approx. 2.8 bar), even when the air outlet valves are open, to ensure the correct function of the oil system.

Compressor

Cooling and oil systems Oil is used for lubrication, sealing and cooling. There is no oil pump with pressure provided by the air pressure. The lower part of the air receiver acts as an oil tank. T he air pressure means that the oil is transported from the air receiver through the oil cooler and oil filter to the c ompressor unit. The compressor unit has an oil platform at the bottom of the sleeve. The oil for rotor lubrication, cooling and sealing is injected through a hole in this oil platform. The bearings are lubricated by oil injected into the bearing housing. The air/oil mixture leaves the compressor unit and returns to the air receiver, where the oil is separated from the air. The oil that is collected at the bottom of the oil separat or returns to the oil system through a cleaning line that has a flow limiter. Note: A thermostat valve bypasses the oil cooler when the oil is below 70°C. 70°C.

Pumps and pilot pressure

Pumps and pilot pressure Pump 1 Main pump 1 in the hydraulic system is an axial piston pump with variable displacement that delivers oil to control the pi lot pressure. The pump is pressure pr essure compensated, which means that the t he pressure is constant irrespective of the flow, so long as the flow is below the maximum capacity of t he pump (150 l/min). The pump pressure can be controlled using external pressure valves or the internal pressure control valve (DR (DR). ). The pump delivers hydraulic power to the t he following functions:  Percussion  Feeding  Feed positioning  Boom positioning  Tramming  RHS system During drilling, pump 1 is controlled by the actual output pressure. During tramming, it is connected to an open circuit system with a flow distributor that distributes the flow equally to left and right tramming motors.

Internal pressure valve During tramming or positioning the internal pressure control valve (DR (DR)) checks the pump

Pumps and pilot pressure

Pump 2 Pump 2 delivers oil to the rock drill’s rotation motor. The maximum pump pressure for pump 2 is set via the relief valve in the drill rotation r otation circuit.

Pump 3 and 4 Pumps 3 and 4 are fitted as a double pump on the diesel engine’s power take off. 

Pump 3 delivers oil to the dust collector’s fan motor during drilling, or to the positioning/winch circuit during tramming. During drilling, the pressure of pump 3 can be set on a relief valve in the DCT valve block. During tramming, the pressure of pump 3 is set constant at 210 bar. Pump 3 is unloaded at engine start-up.  Pump 4 drives the cooler motor for cooling the hydraulic oil, compressor oil as well as engine’s intake air and cooling water. It also delivers oil to the tra ck oscillation lock mechanism. Pump 4 is a gear pump and is driven by the power take off on the side of the diesel engine. The pressure of pump 4 cannot be adjusted but is controlled by the relief valve for the cooling fan. This is set to 160 bar for D5 a nd 220 bar for D7. This pump pu mp is permanently active.

Pilot pressure The oil that controls the pilot pressure comes from pump 1 and pump 3. The oil is led t o the main drilling block/winch block from respective pump through a pressure reducing valve (set to 35 bar), through a strainer and out to the pilot circuit. The oil in the main drilling block is led through solenoid valve Y121, Y121, which guides the pilot pressure

Tramming

Tramming Conditions The tramming circuit includes functions for activating hydraulic functions that maintain the tramming circuit and control the hydraulic power to the tramming motors. Condition for Tramming: - Drilling/Tramming switch S130 must be in a tramming t ramming position. The pilot pressure is led through solenoid valve Y169, Y169, the function of which is to cut the t he pilot pressure flow to tramming and impact functions in an emergency. When solenoid valve Y169 is activated, the oil is led to valve Y121 which then leads the pilot pressure to either the drilling circuit or tramming circuit. Y121 is controlled by switch S130 (see Fig. 1). High and low speed can be selected. If low speed is selected, t he pilot pressure is led through solenoid valve Y121 and then to the directional valve in the main drilling block (see Fig. 2). If high speed is activated, the pilot pressure is led through valve Y122 and on to the valve block for the tramming motors (see Fig. 4).

Tramming direction and speed is controlled b y means of pilot pressure pr essure controlling the proportional directional valves. There directional vavles are controlled by the tramming levers in the cabin (see Fig. 3).

Tramming The valve block integrated in the tramming motors comprises a reversing valve, pilot brake valve and a pilot sequence valve for releasing the tramming brake once the motor is pressurized. The pressure regulator protects the brake cylinder from high pressure. For high-speed tramming, the valves ar e activated by the pilot pressure as in the figure below.

Positioning

Positioning The positioning circuits (including track oscillation circuit) are primarily supplied with oil by pump 1. Since the tramming circuit is also supplied with oil by pump 1, pump 3 has t o be used for positioning during tramming, even when the rig is standing still in tra mming mode. mode. Since pump 1 (250 bar) is larger and works at a higher pressure than pump 3 (160 bar), positioning is more rapid ra pid and powerful in drilling mode than during tramming. The flow from pump 1 is greater than from pump 3.

Boom and feed positioning During tramming, pump 3 delivers oil to the positioning circuit. When the rig is in tr amming mode, solenoid valve Y187 is activated. This pressurizes the pump 3 circuit and connects it via a pressure limiting valve to the positioning circuit (see Fig.). When the rig is not in t ramming mode, the positioning circuit is supplied with oil from pump 1, because pump 3 is then used for supplying the DCT circuit. The positioning cylinders are controlled directly from the positioning levers inside the cab. Lever movement results in valve activation and the pump pressure can pass pa ss out to the cylinder. Positioning can also be handled electrically from the remote control box (see chapter “Option”).

Positioning

Track oscillation The track oscillation cylinders are ar e controlled by directional valves Y419 and Y420 via the control (S176, S176, S177) S177) in the cab. The oscillation cylinders are hydraulically linked by a solenoid valve Y473, Y473, S445. This valve controlled by switch S445. valve has two positions: 

Open position (floating) When Y473 is activated, pilot pressure is delivered to the over centre valves. The ratio 1/13, which means that 25 bar is needed for them to between the over centre valves is 1/13, t o permit oil flow to the cylinders connected in parallel. This position is used for tramming so that unevennesses unevennesses in the ground are compensated for between the two cylinders (see Fig.).  Closed position (locked) When valve Y473 is inactivated there is no flow between the cylinders (over centre valves are closed). This valve position is used make the rig stable sta ble for drilling. Over centre valves

Oil pre-heating

Oil pre-heating Pump 2 is used for pre-heating the hydraulic oil. Normal operating temperature of the hydraulic oil is 40°C. Before operating the drill rig the oil should be pre-heated to minimum operating temperature, 20°C. When switch S130 is in the pre-heating position, solenoid valve Y120A in the main drill block is activated. The oil must pass through a 2 mm restriction and create a pressure by the pressure limiting valve (170 bar). The oil heats up. (See red marker in figure.) Y120A

Drilling Activating percussion The directional valve in the main drilling block has two functions: to lead the oil to the rock drill’s percussion mechanism and to lead the oil to the tramming circuit. The directional valve is controlled by Y101A via the two QDS valves I and J (see figure below). If the damper da mper pressure is lower than 35 bar, valve QDS-I will close. If the pressure exceeds 120 bar, valve QDS-J will close. These QDS valves are part of the DPC-I system and sense the rock drill’s damper pressure. If the damper pressure does not agree, the valves close to prevent the activation of the directional valve.

The threading function is a combined activation of both the feed cylinder and drill rotation motor in a common sector. The hydraulic force to the feed function is supplied by pump 1 and by pump 2 to the rotation function. Activating the threading function When the Drilling/Tramming switch S130 is in drilling position, the solenoid valve Y121 is not activated. This allows the pilot pressure to connect to hydraulic components in the drilling system like the threading/rapid feed lever. 

Threading (Feeding downwards and Rotating CCW) The rapid feed/threading sector, position (B), controls the main directional valves for drill feed and rotation via the LOGIC-2 valve block. It will also activate QDS valve G, which connects the pilot operated pressure reducer with the pressure relief valve for thread feed forward. The pressure relief valve is set to give a feed pressure that corresponds to a feed speed that matches the pitch of the drill steel threads. When the rotation is activated by the threading lever, the rotation flow control is excluded from the circuit. This means

Damper and DPC-I system

Damper and DPC-I system The rock drill's damper circuit is supplied with oil by pump 1 through a constant flow regulator. The flow regulator is adjusted to a pressure of 35 bars at the damper hose connection on the rock drill. The damper pressure during drilling indicates the actual feed force on the drill bit. T he pressure can be read off from the pressure pr essure gauge in the cab on the rig. During drilling, the damper pressure controls certain QDS valves, which in turn control the percussion pressure. This T his is described further under DPC-I system.

Adjusting damper pressure The adjustment of damper pressure must take place with the damper piston in floating position. To ensure that the piston is in floating position the shank adapter must be pulled out as far as possible. Adjusting damper pressure should not be performed before the hydraulic oil has reached normal working temperature, 40ºC (104ºF). 1. Connect a pressure gauge between the damper hose connection and the damper hose on the rock drill. 2. Start the diesel engine and let it run at a t 1500 rpm. 3. Make sure that the shank adapter is fully withdrawn, i.e. the damper piston is in the floating position. 4. Set S130 in drilling position. 5. Undo the lock screw (8b) on the knob and adjust the damper pressure by turning the knob (8a):

Protective protections

Protective protections Anti-jamming The anti-jamming protection is an automatic monitoring function that is always active during drilling. The anti-jamming function is activated by high rotation pressure or lack of air flushing flow during drilling. Logic function of the lever Since the anti-jamming inverts the feed direction, pulling the drill lever for feeding backwards would B262, connected to the pilot result in feed forward movement. To avoid this there is a pressure switch, B262, X33, which, when active, inhibits pressure line for feed backwards. B262 is connected to PLC input X33, Y2. the anti-jamming output Y2.

HQS (Hole Quality System)

HQS (Hole Quality System) This document only covers the interface between the HQS system and the rig system. For detailed information of the HQS system, refer to the HQS section in the Operators manual. HQS is a complete system for gradient measurement, hole depth measurement on bench drill r igs. There are three kinds of HQS equipments to choose from. HQS 10 - Complete instrument for hole inclination measurement. measurement. HQS 11 - Complete instrument for measuring angles, hole depth and drilling r ate. Hole depth measurement. HQS 12 - Complete instrument for measuring angles, hole depth and drilling r ate from laser reference r eference.. The HQS system is linked to the rig system for power supply, activation of the drill stop function and definition of impact / rodhandling. Power supply The power supply for the HQS unit is connected to terminal X1/50 (24V) and X1/100 (Ground) in the A1 electrical cabinet. Drill stop activation The HQS supports a function to automatically stop the impact when a pr edefined drill depth is X43. It will then deactivate reached. The HQS electronic unit sends a 24V signal to activate PLC input X43.

RHS, Rod handling system

RHS, Rod handling system General The functions for the different rod r od handling movements are controlled manually from the left-hand panel on the seat. All actuation signals run via the PLC out to t he respective valve for the RHS functions (see figure below). There are a number of sensors on the feed beam which then gauge the activity in the system and send signals in to the PLC (see the explanation of how the sensors work at the end of this section).

System pressure Max. pressure for the rod handling circuit is determined by a pressure reducing valve at 200 bars. There is also a separate pressure regulating valve to the suct ion hood (40 bars) to prevent the cylinder breaking and one for the grip function (10 bars) which limits the pressure for “loose grip” (see hydraulic diagram).

Extraction unit (option) The extractor unit is used when the rock conditions vary a lot and there is a large risk of jamming. The function of the extractor unit is to provide reverse percussion to the shank adapter and thus the drill sting and drill bit. The shank adapter for rock drills equipped with an extractor unit has a special flange that receives the reverse percussion force. Since the shank adapter is pressed into the rock drill by the feed force during normal drilling, it works without the flange meeting the extractor piston. Conditions for extraction unit:  The rig must be in drilling mode.  Percussion must be activated. For the extraction unit to be activated the above conditions must be fulfilled.
