Description

Technical Field

[0001] The utility model belongs to the technical field of gas drilling, and more specifically, relates to a positioning device for gas pressure measurement drilling in mining areas. Background Art

[0002] Gas explosion is a serious safety hazard in the mining industry, which can lead to catastrophic consequences. Gas pressure measurement drilling helps to detect abnormal situations early and prevent explosion accidents by monitoring the pressure and concentration of underground gas in real time. This is crucial for protecting the lives and safety of miners. Accurate gas data helps to formulate reasonable ventilation systems and gas emission plans, thereby improving the production efficiency and safety of mining areas. By analyzing gas data, mining area managers can optimize the mining plan and reduce production stagnation and economic losses caused by gas.

[0003] During the drilling construction process, the positioning of the drill bit usually relies on marks on the ground. The main problem with this marking method is that when the drilling starts, the drill bit rotates and advances continuously, which will damage the marks on the ground. This damage will cause the marks to gradually disappear or become blurred, making the originally used marks unable to continue providing accurate references. As the drilling depth increases, the problem of ground mark damage will become more serious. The operation of the drilling equipment will not only cause physical damage to the mark position, but may also change the actual state of the ground, causing the drill bit to slide on the ground, resulting in a further increase in the drilling error.

[0004] In summary, there is a problem in gas pressure measurement drilling in mining areas that the drill bit is prone to sliding, resulting in deviation of the drilling location. Summary of the Utility Model

[0005] In view of this, the utility model provides a positioning device for gas pressure measurement drilling in mining areas, which can solve the problem that the drill bit is prone to sliding in gas pressure measurement drilling in mining areas, resulting in deviation of the drilling location.

[0006] The utility model is implemented as follows:

[0007] The utility model provides a positioning device for gas pressure measurement boreholes in a mining area, which includes a positioning column, positioning teeth, a rotating assembly, a guiding assembly, a cover plate and a locking assembly. The positioning column is of a cylindrical structure. The positioning teeth are fixedly connected to the lower bottom surface of the positioning column. The positioning teeth are inserted into the soil in the mining area to fix the position of the positioning column. The rotating assembly is rotatably connected to the positioning column. The rotating assembly is fixedly connected to the guiding assembly. The guiding assembly is located above the rotating assembly. The cover plate is sleeved above the guiding assembly. The cover plate is used to cover the dust of the borehole. The side wall of the cover plate is arranged with gratings. The cover plate is fixedly connected to the positioning column. The cover plate is slidably connected to the guiding assembly. The cover plate and the locking assembly are connected by a groove in a snap-fit manner.

[0008] The technical effects of the positioning device for gas pressure measurement boreholes in a mining area provided by the utility model are as follows: By setting the positioning teeth, the friction between the positioning column and the ground can be increased, and at the same time, the grip of the positioning column can be increased, ensuring that the positioning column remains stable during the borehole drilling process, avoiding slipping or offset, thereby improving the accuracy and consistency of the borehole. By setting the rotating assembly and the guiding assembly, the operator can accurately adjust the position and size of the borehole, ensuring that the borehole is drilled at a predetermined precise position. This reduces the risk of the borehole deviating from the target position, especially in application scenarios that require high-precision boreholes. By accurately setting the borehole range and operating within a limited space, the risk of the drill bit deviating from the target position can be reduced, improving the overall accuracy of the borehole. At the same time, the defined borehole range can prevent the drill bit from sliding or moving, improving the stability and reliability of the operation. By setting the locking assembly, the guiding assembly can be locked, avoiding the guiding assembly from sliding during the gas pressure measurement borehole drilling process, resulting in an increase in the borehole range.
