Description

Technical Field

[0001] This utility model relates to the field of gas drilling rig technology, specifically to an underground gas drilling rig that avoids the influence of gas concentration. Background Technology

[0002] As mines develop deeper, the gas content gradually increases, and the risk of coal and gas outbursts becomes increasingly serious. The problem of excessive gas levels has become a prominent issue restricting safe production and sustainable development in mines. According to relevant regulations and requirements for gas area management, gas management measures mainly involve constructing gas extraction roadways and extraction boreholes in the top and bottom of the coal seam to extract gas. After the gas extraction roadway is constructed, it is necessary to construct gas extraction boreholes in the roadway towards the coal seam in order to install extraction pipelines for gas extraction. Currently, most mines use mining crawler drilling rigs for gas extraction boreholes.

[0003] A current mining tracked drilling rig (CN202122794935.X) uses an impact force to move a buffer plate downwards. The buffer plate, through a transmission column, moves a buffer rod downwards, which in turn moves a connecting rod outwards. The connecting rod then moves an inclined plate outwards, and a return spring restores the inclined plate to its original position. This facilitates the removal of impact force on the track and protects it. The addition of a locking mechanism allows for easy installation and removal of drill bits, making drill bit replacement convenient. However, this system has shortcomings. It cannot handle methane concentration and cannot quickly manage the environment, potentially leading to methane leaks and unsafe construction. Furthermore, it lacks remote control capabilities. Therefore, a new underground methane drilling rig that avoids the influence of methane concentration is needed to address these issues. Utility Model Content

The control host 3 is electrically connected to the drive wheels 2, electric shaft 8, gas extraction pump 11, ventilation fan 13, auxiliary support column 14, camera 17, servo motor 21 and gas detector 22. The control host 3 is a PLC device with an integrated data transmission unit or industrial router. The cameras 17 are arranged in a ring on the vehicle body 1. This allows the control host 3 to be centrally controlled and remotely operated, making it safer to use.

[0020] An electric rotating shaft 8 is installed on the other side of the upper part of the vehicle body 1, and a drilling rig body 5 is installed on the other side of the electric rotating shaft 8. The drilling rig body 5 and the drill bit 6 are vertically flipped and connected to the vehicle body 1 through the electric rotating shaft 8. The drilling rig body 5 is installed in a support fit with the support groove 18 through the pad 19. This makes it easy to flip and adjust the drilling rig body 5 and the drill bit 6, and makes it easy to store stably and make it safer to use. The drill bit 6 is inserted and installed on the inner wall of the drilling rig body 5, and a gas detector 22 is installed on the lower end of the outer wall of the drilling rig body 5. The gas detector 22 is distributed in a ring position on the outer wall of the drilling rig body 5. The suction port 23 is symmetrically distributed in two sets on the drilling rig body 5. The suction port 23 is connected to the gas drainage pump 11 through the suction conduit 10. This allows the gas detector 22 to detect the gas concentration and remove the gas through the suction port 23 to avoid danger.

[0021] An air outlet 7 is installed at the lower end of one side of the drilling rig body 5, and an air guide pipe 9 is connected to the upper end of the air outlet 7. The air outlet 7 is connected to the ventilation fan 13 through the air guide pipe 9. The air outlet 7 is distributed in an arc shape on one side of the outer wall of the drilling rig body 5. The ventilation fan 13 is a frequency conversion structure, which allows the air outlet 7 to blow air more efficiently and effectively reduce the gas concentration.

[0022] A gas extraction pump 11 is vertically fixedly connected to the middle of the upper part of the vehicle body 1, and a ventilator 13 is installed on the front side of the gas extraction pump 11. The ventilator 13 is connected to the air duct 9. A support groove 18 is opened at the upper end of the gas extraction pump 11, and a pad 19 is fixedly connected to the lower end of the inner wall of the support groove 18. Suction ports 23 are installed on the lower edges of the front and rear sides of the drilling rig body 5, and a suction pipe 10 is connected to the upper end of the suction port 23. The other end of the suction pipe 10 is connected to the gas extraction pump 11, and a delivery pipe 12 is connected to the other side of the gas extraction pump 11. A camera 17 is protruding from the outer edge of the vehicle body 1, and a servo motor is fixedly connected to the front and rear edges of the vehicle body 1. The output end of the servo motor 21 is fitted with a rotating sleeve 20, and a crossbar 16 is fixedly connected to one side of the rotating sleeve 20.

The auxiliary support column 14 and the crossbar 16 are connected to the vehicle body 1 in a reset and flipping manner through the rotating sleeve 20 and the servo motor 21. The auxiliary support column 14 is a hydraulic telescopic structure, and the support foot pad 15 is telescopically connected to the crossbar 16 through the auxiliary support column 14. This makes it easy for the auxiliary support column 14 and the crossbar 16 to open and close automatically, and provides stable support and safer use. A driver's seat 4 is installed on one side of the vehicle body 1.

[0023] Working principle: When using this type of underground gas drilling rig that avoids the influence of gas concentration, the device is first moved to the mine shaft, and the delivery pipe 12 is connected to the mine's gas drainage system. The auxiliary support column 14 and crossbar 16 are then rotated and unfolded via the rotating sleeve 20 and servo motor 21. Next, the support foot pads 15 are lowered via the auxiliary support column 14 for auxiliary support and fixation. Then, the drilling rig body 5 is rotated to a vertical position via the electric rotating shaft 8. The drilling rig body 5 then drives the drill bit 6 to drill a hole. Finally, the gas concentration is monitored by the gas detector 22. Real-time monitoring is performed. When the concentration is too high, the gas extraction pump 11 and the ventilation fan 13 can be started. Air is blown and sucked through the air outlet 7 and the suction port 23 to reduce the gas concentration. The frequency of the gas extraction pump 11 and the ventilation fan 13 can be adjusted in real time according to the concentration. When it is inconvenient to operate on-site, it can be remotely controlled visually through the control host 3 and the camera 17. After completion, the drilling rig body 5 can be flipped over and stored, and supported and fixed by the support groove 18 and the pad block 19. This is the usage process of this kind of underground gas drilling rig that avoids the influence of gas concentration.
