Description

Technical Field

[0001] The present invention relates to the technical field of mining drilling equipment, and in particular to a drilling rig posture adjustment device and a mining drilling rig. Background Art

[0002] At present, underground coal mines often need to precisely control directional drilling rigs to carry out through-layer drilling construction in order to carry out at least one of the following tasks: gas extraction, water exploration and drainage drilling, and bottom plate grouting. When performing the above-mentioned drilling operations, mining-used high-angle drilling rigs are usually used for high-angle drilling (i.e., the actual borehole has a large angle between the axial direction and the vertical direction).

[0003] However, during the process of drilling at a high angle, the mining drill rig used in the prior art is very likely to experience changes in the drilling rig's inclination (i.e., the angle between the drill bit's rotation axis and the vertical direction), height, and azimuth (i.e., the angle between the drill bit's rotation axis and the horizontal direction) due to the influence of factors such as vibration of drilling tools such as the drill bit in the hole and possible leakage of the hydraulic system. In order to ensure the drilling accuracy, it is necessary to frequently interrupt the drilling operation of the mining drill rig to adjust the drilling rig's inclination, height, and azimuth, which not only seriously reduces the drilling efficiency, but also increases the overall drilling construction time, which is not conducive to efficient construction operations in mines. In addition, if the drilling rig's inclination, height, and azimuth are not adjusted in a timely and effective manner, the force on drilling tools such as the drill bit will increase during the drilling process, which will easily lead to problems such as damage to the drilling tools and poor working stability of the drilling rig, which will not only threaten the personal safety of the staff, but also reduce the service life of the mining drill rig.
