Description

Technical Field

[0001] This utility model relates to the field of coal mine drilling rig technology, and in particular to a hydraulic deep hole drilling rig with a top protection mechanism. Background Technology

[0002] In the field of deep-hole drilling in mines, the roof support device of a hydraulic drilling rig, as a key component ensuring operational safety, has long been hampered by deficiencies in structural design and functional integration. The current state of industry technology and existing problems are mainly reflected in the following aspects:

[0003] (1) Single dimension of roof protection adjustment: At present, most roof protection devices adopt fixed frames or simple lifting structures, which can only realize vertical lifting function. They cannot dynamically adjust the roof protection posture according to the borehole inclination angle (such as ±30° adjustment required by the goaf-keeping tunnel roof cutting eye), and cannot adjust the posture according to the borehole angle, resulting in limited protection area, especially in complex geological conditions.

[0004] (2) Low efficiency of blowout prevention and sewage discharge: Most existing blowout prevention devices use passive waterproof cloth or simple water collection tanks, with a sewage collection rate of less than 50%. Under the impact of high-pressure water jets, overflow is likely to occur, which aggravates the pollution of the working face and the corrosion of equipment. Some mines have tried to introduce tapered expansion sealing technology, but its structure is complex and requires frequent manual maintenance, making it difficult to integrate into the mobile drilling platform.

[0005] (3) Insufficient stability design: The roof support device generally lacks an anti-overturning mechanism. It is prone to displacement or even overturning under the impact of water pressure above 1.5MPa or the vibration of the drilling rig. The Xiegou Coal Mine once had a drilling displacement accident caused by the instability of the roof support, which seriously affected the construction progress.

[0006] (4) Lagging automation: Existing regulation mechanisms mostly rely on manual operation, which has a slow response speed and poses safety hazards. Utility Model Content
