[0022] The following describes the drilling equipment operation method according to the embodiment of the present disclosure with reference to the accompanying drawings.
[0023] The present invention provides a drilling equipment operation method device and electronic equipment, the main purpose of which is to solve the technical problem that the current traditional drilling operation process often focuses on operation efficiency and cost control, but ignores the comprehensive assessment and effective management of safety risks. Due to the lack of systematic safety risk analysis, the potential safety hazards and potential dangers that may exist in the operation process are often ignored or underestimated, resulting in frequent drilling operation safety accidents.
[0024] like Figure 1 As shown, an embodiment of the present disclosure provides a drilling equipment operation method, the method comprising:
[0025] Step 101: Check whether the mechanical parts, other parts, operating table and working environment of the drilling equipment meet the standard working conditions.
[0026] like Figure 2 As shown, before the drilling operation begins, it is necessary to first conduct a safety check of the drilling equipment and its working environment (i.e., a pre-startup check) to ensure that everything is normal.
[0027] Specifically, it is possible to check whether the mechanical parts, other parts, operating table and working environment of the drilling equipment meet the standard operating conditions.
[0028] Among them, the mechanical parts may include: walking structure, track shoe pins, drill bit cones, nozzles, gear teeth, drill racks, pin connections of various parts and chains;
[0029] Other components may include: lubrication, lighting, horns, wipers, fire fighting equipment, dust hoods, hydraulic systems, oil levels, indicator lights, indicators, dry dust removal ducts, air filter dust pans, oil-gas separators, oil-water separators, centralized lubrication water collection cups, fuel systems, battery wiring, electrolyte levels and battery vents;
[0030] The operating console may include: handles and switches, emergency stop buttons and alarm signals.
[0031] Standard operating conditions may include:
[0032] The walking structure has no open welding, breakage, deformation, looseness or damage; the track shoe pin shaft has no movement, breakage or deformation; the drill bit cone rotates flexibly; the nozzle is unobstructed; the gear teeth are not worn excessively; the drill rack has no open welding, breakage, deformation, looseness or damage; the pin shafts of each part are connected intact; the chain has no breakage and the tightness is normal;
[0033] Lubricating parts are well lubricated; lighting, horns, wipers, and fire-fighting equipment are complete and effective; dust hoods are not cracked, and there is no accumulation of rock debris or freezing; there is no leakage in the hydraulic system; the oil level is normal, and the indicator lights and indicators are complete and intact; the dry dust removal air duct is not blocked; the air filter dust collecting plate, oil-gas separator, oil-water separator, and centralized lubrication water collection cup are cleanly drained; there is no leakage in the fuel system; the battery wiring is tight, the electrolyte level is normal, and the battery vent is unobstructed;
[0034] The handle and switch are in the zero position or the closed position; the emergency stop button and the alarm signal display are normal;
[0035] The working environment has a flat surface, no obstacles around, and no high-voltage wires overhead.
[0036] For each of the above inspections, if any problems are found, the corresponding record can be filled in the shift record book, such as "equipment failure or hidden dangers"; if the inspection is not carried out as required, the corresponding record can be filled in the shift record book, such as "equipment not inspected as required".
[0037] Step 102: If the mechanical parts, other parts, operating table and their working environment meet the standard working conditions, the working environment of the drilling equipment is checked again to ensure that there are no personnel and obstacles within the preset range of the drilling equipment, and the rotating parts of the drilling equipment are checked to ensure that the rotating parts of the drilling equipment are in normal condition.
[0038] like Figure 2 As shown, before starting the equipment, it is necessary to confirm again that all preparations have been completed (i.e., pre-startup confirmation) and meet the operating requirements.
[0039] Specifically, if the mechanical parts, other parts, operating tables and their operating environment meet the standard operating conditions, the operating environment of the drilling equipment shall be checked again to ensure that there are no personnel and obstacles within the preset range of the drilling equipment, so as to ensure that during the startup and operation of the drilling equipment, no injury or damage will be caused by the approach of personnel or obstruction of objects; and the rotating parts of the drilling equipment shall be checked to ensure that the rotating parts of the drilling equipment are in normal condition.
[0040] Among them, the rotating parts such as drill bits, drive shafts, etc., for example, check whether the drill bit is firmly installed, whether the drive shaft has abnormal vibration or noise, and whether there are any objects that may hinder the rotation.
[0041] Step 103, start the engine of the drilling equipment, and control the engine to idle for a preset period of time to check whether the various parts or assemblies of the drilling equipment, the oil pressure of the engine and the exhaust color after starting meet the operating standard conditions.
[0042] like Figure 2 As shown, after executing step 101 and step 102, the drilling equipment can be officially started (i.e., started) to start the operation, and after the drilling equipment is started, a preliminary inspection (i.e., post-startup inspection) is performed to ensure that the drilling equipment operates normally.
[0043] Specifically, before starting the equipment, first, sound the horn to warn people around you to ensure their safety. Turn the engine speed switch to the idle position to reduce the load during startup; disconnect the air conditioner power supply to avoid adding unnecessary power load during the startup process.
[0044] Turn the drilling switch or travel switch of the drilling equipment to the drilling position and prepare for drilling operations.
[0045] Turn the key switch of the drilling equipment to the "ON" position (i.e. the opening position), and the two self-test lights of the engine will light up. If any of the self-test lights is off, it means that the equipment is faulty and must not be started. When both self-test lights are off, it means that the equipment has passed the self-test, and you can press the bypass switch and the host start button at the same time to start the engine.
[0046] When the engine speed reaches 1200 rpm, release the main engine start button. At the same time, the oil pressure should reach 25psi, then you can release the bypass switch.
[0047] Normal continuous starting time should not exceed 30 seconds. If the engine does not start, the interval between restarts should not be less than 2 minutes to avoid overheating and damage to the engine.
[0048] For the disclosed embodiment, after the engine is started, the oil pressure can first be checked to see if it is within the preset normal pressure value range to ensure that the engine lubrication system is working properly. Then, the operation of each part or assembly of the drilling equipment after startup can be checked, such as the operation sound, vibration and abnormal sound, to ensure that each part or assembly of the drilling equipment has no leakage, and the operation sound has no vibration and abnormal sound.
[0049] You can observe the color of the engine exhaust, which can reflect its combustion status. Normal exhaust color should be colorless or light gray. If the exhaust color is abnormal (such as black smoke, blue smoke, etc.), it means that there is a problem with the engine.
[0050] After starting the engine, the engine can be allowed to idle for 3 to 5 minutes for further inspection. The engine should not idle continuously for more than 30 minutes to avoid overheating and wear.
[0051] If any abnormality is found during startup or post-startup inspection, stop using the equipment immediately and notify a professional for maintenance.
[0052] Step 104: If the parts or assemblies of the drilling equipment, the oil pressure of the engine and the exhaust color meet the standard operating conditions, the engine speed is adjusted to 1800 revolutions per minute, and the drilling equipment is operated accordingly according to different walking distances, so that the drilling equipment can walk to the target drilling operation location.
[0053] After confirming that everything is normal, the engine speed can be adjusted to 1800 rpm to prepare for drilling operations, and if Figure 2 As shown, corresponding walking operations (i.e., long-distance and short-distance walking) can be performed on the drilling equipment according to different walking distances, so that the drilling equipment can walk to the target drilling operation site, wherein different walking distances may include long-distance walking and short-distance walking.
[0054] For the embodiment of the present disclosure, if the walking is long distance, the drilling tool can be lifted off the ground to the top before the long distance walking to avoid the drilling tool contacting the ground during walking and damaging the drilling tool or the drill hole; the drill frame can be laid flat or lowered to an appropriate position to ensure the stability of the drilling equipment during walking; the jack can be retracted, wherein the jack can be a component used to support the drilling equipment and the drilling tool, and it needs to be fully retracted before walking.
[0055] According to the instructions of the ground commander, the drilling or walking switch can be turned to the walking position, and the walking handle can be operated to start the drilling equipment to walk on roads with different slopes, so that the drilling equipment can walk to the target drilling operation site.
[0056] When drilling equipment travels on roads with different slopes, certain slope restrictions need to be observed to ensure safety.
[0057] Specifically, if the drilling equipment is laid flat on the rig, the downhill slope shall not exceed 25 degrees, and the uphill slope shall not exceed 19 degrees; if walking on the side ramp, the slope shall not exceed 22 degrees; if crossing high-voltage overhead lines, the distance from 35 kV high-voltage lines shall be no less than 5 meters, and the distance from 6 kV high-voltage lines shall be no less than 2 meters. Do not work under the overhead lines to avoid dangers such as electric shock;
[0058] When the blasting step is within 10 meters from the top of the slope, the drilling equipment is not allowed to move parallel to the top of the slope. In the areas of umbrella eaves and cracks, the distance from the top of the slope must be increased to avoid dangers such as landslides or collapses.
[0059] For the embodiment of the present disclosure, if the walking is short distance, the drill bit can be lifted at least 50 cm off the ground before walking short distance to avoid damage to the drill bit or the borehole due to contact with the ground during walking; the jack can be retracted, wherein the jack can be a component used to support the drilling equipment and the drill bit, and it needs to be fully retracted before walking.
[0060] According to the instructions of the ground commander, the drilling or walking switch can be turned to the walking position, and the walking handle can be operated to start the drilling equipment to walk on roads with different slopes, so that the drilling equipment can walk to the target drilling operation site.
[0061] When drilling equipment travels on roads with different slopes, certain slope restrictions need to be observed to ensure safety.
[0062] Specifically, if the drilling equipment is walking with the drill rig erected, the downhill slope shall not exceed 12 degrees, and the uphill slope shall not exceed 22 degrees; if walking on the side ramp, the slope shall not exceed 17 degrees; if crossing high-voltage overhead lines, the distance from 35 kV high-voltage lines shall be no less than 5 meters, and the distance from 6 kV high-voltage lines shall be no less than 2 meters, and no work shall be done under the overhead lines to avoid dangers such as electric shock;
[0063] When the blasting step is within 10 meters from the top of the slope, the drilling equipment is not allowed to move parallel to the top of the slope. In the areas of umbrella eaves and cracks, the distance from the top of the slope must be increased to avoid dangers such as landslides or collapses.
[0064] Step 105, align the drilling position of the drilling equipment to the target drilling position, lift the drilling frame of the drilling equipment to the target height, start the rotation function of the drilling tool of the drilling equipment to perform drilling operations until the drilling depth reaches the target depth, the drilling tool includes a drill bit and multiple drill rods.
[0065] like Figure 2 As shown, after the drilling equipment moves to the target drilling operation site, the drilling position of the drilling equipment can be aligned with the target drilling position (i.e., the hole position) to ensure the accuracy of the drilling, and the drill frame of the drilling equipment can be lifted to the target height (i.e., the drill frame is lifted) to carry out the drilling operation; then, the formal drilling operation begins, and the drill rod and drill bit are used to penetrate the formation (i.e., drill) until the drilling depth reaches the target depth.
[0066] Specifically, the drilling equipment can be leveled using a jack and a level before drilling to ensure the verticality and accuracy of the drilled hole. The jack can be used to support and adjust the height of the drilling equipment, and the level can be used to detect the horizontal state of the drilling equipment.
[0067] The dust hood switch can be pressed to lower the dust hood and close the dust hood door. The dust hood can be used to capture dust generated during the drilling process to protect the environment and the health of operators. Before drilling, it is necessary to ensure that the dust hood has been properly installed and closed.
[0068] Then, the drilling position of the drilling equipment can be aligned to the target drilling position, wherein the hole position error between the drilling position and the target drilling position is less than or equal to 20 centimeters to ensure the accuracy and efficiency of the drilling.
[0069] Before lifting the drill rack, check whether the drill rack lock pin is in the correct position to ensure that the drill rack will not fall off or be damaged during the lifting process. Check the tools, spare parts, etc. on the drill rack to ensure that there are no tools, spare parts, etc. left on the drill rack to avoid falling and injuring people or damaging equipment during the lifting process.
[0070] Before lifting the drill rig, check the level again to ensure that the drilling equipment remains level during the lifting process.
[0071] Before lifting the drill rack, you need to turn the derrick lock switch to the "unlocked" position so that the drill rack can be lifted smoothly.
[0072] The handle can be operated according to the prescribed steps to slowly lift the drill frame to the target height, and the derrick locking switch can be turned to the "locked" position, which locks the two pins to ensure the stability and safety of the drill frame during operation.
[0073] When the drill tool is drilling, it can be lowered slowly to avoid sudden impact or damage, and the drill tool air supply valve can be opened to provide air power to the drill tool for dust removal or cooling.
[0074] Start the rotary function of the drill, start drilling, and turn on the dry dust collector to remove dust generated during drilling. When the drill bit of the drill is close to the ground, the feed pressure of the drill bit can be adjusted according to the actual situation to ensure smooth drilling.
[0075] The drilling can be continued by connecting and disconnecting the drill rod until the drilling depth reaches the target depth, wherein the hole depth error between the drilling depth and the target depth does not exceed 50 cm;
[0076] When the drill bit enters the hole to a depth of 1 meter, the feed pressure and speed can be appropriately increased;
[0077] During the drilling process, the indications of various instruments can be continuously monitored to ensure the normal operation of the machine.
[0078] For the embodiments of the present disclosure, Figure 2 As shown, drilling is continued until the target depth of the borehole reaches the target depth by connecting and disconnecting the drill rod (i.e., disconnecting the drill rod and connecting the drill rod). Specifically, after the first drill rod of the drilling tool completes the current drilling operation, the first drill rod can be disconnected. As a possible implementation method, the first drill rod can be clamped with a caliper, and the reverse function is started to disconnect the first drill rod, and the drill rod thread of the first drill rod is checked to ensure that the drill rod thread is free of impurities and grease is applied to the drill rod thread.
[0079] When connecting a new drill rod, the lifting mechanism of the drilling equipment can be used to lift the rotary trolley with the new drill rod to the top of the drilling tower so that the drill rod can be easily taken out; turn the rod storage device to adjust the center line of the new drill rod to align it with the center line of the rotary joint of the drilling equipment;
[0080] Slowly lower the rotary trolley and rotate the new drill rod so that the thread of the new drill rod is connected with the thread of the rotary joint, lift the new drill rod out of the rod storage device, and return the rod storage device to its original position;
[0081] Lower the rotary trolley, connect the lower end of the new drill rod with the upper end of the first drill rod, and rotate the new drill rod so that the thread of the new drill rod is tightly connected with the thread of the first drill rod;
[0082] The drilling operation is carried out using the connected new drill rod and the first drill rod until the drilling depth reaches the target depth.
[0083] If it is necessary to connect the third drill rod, the positioning lock pin of the rod storage device can be opened, the rod storage device can be rotated, the third drill rod can be rotated out, and the positioning lock pin can be locked.
[0084] Step 106, stop feeding the drill rod, start the lifting mechanism, lift the lower interface of the multiple drill rods to the caliper position for unloading, release the rod holder, and continue to lift the drill rod until the drill tool is completely lifted off the ground.
[0085] like Figure 2 As shown, after the drilling depth reaches the target depth, the drill rod can be lifted out of the borehole (i.e., lifting the rod).
[0086] For the disclosed embodiment, specifically, after the drilling depth reaches the target depth, the handle for controlling the feeding of the drill rod can be turned to zero position to stop the further feeding of the drill rod. Then, air is supplied to the bottom of the borehole to clean the rock slag and drill cuttings at the bottom of the hole.
[0087] After the rock slag and drill cuttings are exhausted, the handle can be turned to the lifting position to start the lifting mechanism and lift the drill rod. During the lifting process, ensure that the lower interface of the lower drill rod among the multiple drill rods is lifted to the caliper position for subsequent unloading operations.
[0088] When the lower interface of the lower drill rod is lifted to the clamp position, the first drill rod can be unloaded from the lower drill rod, and the rod storage device is retracted to store the unloaded drill rod.
[0089] The rotary trolley can be used to move the lower drill pipe to the appropriate position and connect it to facilitate subsequent operations.
[0090] You can loosen the rod holder and continue to lift the drill rod until the drill tool is completely lifted off the ground.
[0091] The above steps can be performed sequentially until all drill rods are lifted off the ground. When the drill bit approaches the ground surface, the air supply to the bottom of the borehole can be stopped.
[0092] It should be noted that the lifting steps must be accurate and correct to ensure the safety and efficiency of the operation;
[0093] The drill rod out of the hole should be cleaned and free of drilling cuttings to avoid interference with subsequent operations;
[0094] Keep rotating when lifting the rod and supply air to the bottom of the hole to help clean the cuttings on the bottom of the hole and the drill rod;
[0095] After the drill bit is lifted to a certain height from the ground, the rotary handle and feed handle should be in the middle position to ensure the stability and safety of the equipment.
[0096] Step 107, lower the drill rig, place the lowered drill rig on the drill rig support seat, lock the drill rig, and shut down the drilling equipment.
[0097] like Figure 2 As shown, after the drill rod is lifted out of the borehole, the drill rack can be lowered, and the lowered drill rack can be placed on a drill rack support seat, the drill rack can be locked, and the drilling equipment can be shut down.
[0098] Specifically, when the drilling rig is lowered, the drilling rig locking switch can be turned to an unlocked position to unlock the drilling rig;
[0099] Then, you can pull the handle to the rising position for 1-2 seconds to fill the lower chamber of the oil cylinder with oil. Then, pull the handle to the lowering position and start lowering the drill rack, making sure that the drill rack is placed smoothly on the drill rack support to avoid damage to equipment and personnel.
[0100] Finally, lock the rig by turning the rig lock switch to the locked position.
[0101] When shutting down, first lift all the drill rods to avoid damage caused by contact with the ground; then, put away the dust cover to reduce the accumulation of dust and debris; then, retract the jack to ensure that it will not interfere with subsequent movement or operation; move the drilling equipment away from the drilling location for subsequent cleaning or maintenance work.
[0102] Move all handles to the middle position to ensure the equipment is in a safe state.
[0103] Check whether the key switch is turned to the "OFF" position (i.e., the closed position) and turn off the engine to end the operation of the drilling equipment.
[0104] Finally, during the shift handover of drilling equipment, the operation records of the drilling equipment and any faults or hidden dangers of the equipment can be filled in in a standardized, clear and concise manner in the shift handover record book.
[0105] In summary, the use of this drilling equipment operation method can ensure that the drilling operation process conducts a comprehensive assessment of safety risks, thereby reducing the incidence of safety accidents in drilling operations.
