Problems solved by technology

[0003] Now it is necessary to use an all-round drilling rig to drill holes in different positions. The existing drilling rig generally uses an oil cylinder to push the drilling rig to move up and down along the column, thereby adjusting the position and height of the drilling rig. The hydraulic lock of the oil cylinder keeps the drilling rig at a certain height. The method has the following shortcomings; if the hydraulic lock fails, it will cause certain safety accidents; during the working process of the drilling rig, the vibration generated is directly transmitted to the oil cylinder, which will affect the service life of the seal between the cylinder body, the piston rod and the piston, Increased the failure rate of oil cylinder leakage, causing the drilling rig to slide during work, affecting the normal use of the drilling rig

Abstract

The invention provides a full-roadway drilling posture adjusting device for a coal mine drilling rig. The full-roadway drilling posture adjusting device comprises a mounting platform, a first rotary device, an anchorage frame, a fixing seat, a second rotary device and a thrust mechanism. According to the full-roadway drilling posture adjusting device, combination adjustment of the first rotary device and the second rotary device is adopted, so that adjustment of the roadway drilling posture is achieved; two anchorage vertical column assemblies and a guiding column assembly are adopted to constitute the triangular anchorage frame, and thus the supporting rigidity and anchorage stability are good; locking mechanisms which conveniently anchor the fixing seat on the anchorage vertical column assemblies are arranged at the lower end of the fixing seat, and thus safety accidents, caused by a failure of a hydraulic lock, of the drilling rig are avoided; and meanwhile the situation that vibration in the working process of the drilling rig is transmitted to an oil cylinder, and consequently the service life of the oil cylinder is affected is avoided.
