Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal mine drilling machine, especially to a multifunctional cross-belt deep hole drilling rig for coal mine. BACKGROUND

[0002] The geological conditions of coal fields in China are complex, and natural disasters such as gas, water damage and high ground stress seriously restrict the safety production of coal mines. In the process of coal mining, it is necessary to frequently construct roof cutting drilling holes, and through roof cutting drilling holes or combined with blasting methods, the roof can be timely and fully free to collapse, so as to reduce the pressure of coal body, or the collapsed rock fills the goaf to reduce the accumulation of gas, and ensure the safety of the operation area. When carrying out roof cutting operation, after the support column outside the necessary operation area is returned, it is required that the roof can collapse along a line according to the set requirements. On this line, one side is the supported area, and the other side is the roof collapse area. This dividing line is the roof collapse line, that is, the roof cutting line. For coal mine environment which needs both roof cutting and drilling, the current solution is to use roof cutting machine and anchor rod drilling machine separately, which increases the cost of coal mining and reduces the efficiency of operation in the mine.

[0003] The existing coal mining layer generally has a roadway for drilling, and a coal conveying belt is arranged in the middle of the roadway. The space between the coal conveying belt and the coal mining layer is limited. At present, the drilling equipment is mainly track type single-arm drilling machine or double-suspension arm drilling machine. The drilling machine equipment is large in size and heavy in whole. In the small space between the coal mining layer and the coal conveying belt, it is difficult to carry out normal work, so a cross-belt drilling rig is needed.

However, it is found in actual use that the positioning structure is relatively simple, and only small-range drilling positioning can be realized. The entire drilling rig often needs to be moved to realize accurate positioning, which greatly reduces the construction efficiency.

[0005] Therefore, there is an urgent need for a multifunctional cross-belt deep hole drilling rig for coal mine. UTILITY MODEL CONTENTS
