Description

Technical Field

[0001] The present invention relates to the technical field of underground mining, and more particularly to a support system for a mining roof and a bolter for underground mining. Background Art

[0002] Mining refers to the technology and science of mining mineral resources from the earth's crust and surface. When mining mineral resources in the earth's crust, it is necessary to combine the mining roof and the bolter to operate, so that the mining roof can determine its own position height through a special support system. For this reason, the rock layer of the underground mine can be fixed, avoiding the collapse of the rock layer during the mine operation, and thus effectively improving the safety of underground mining; Then, during underground mining, the bolter can be used for operation. The bolter's high power and high efficiency can effectively use the special drill to drill underground rocks at high speed and high quality, so that it can effectively and stably complete the underground mining work. In addition, the mining roof combined with the support system can avoid rock collapse caused by the drilling process. In summary, the inventors have found that the existing mining roof support system and underground mining bolter have the following main defects: when the current mining roof is installed on the top floor of the underground mine through the support system, when the mining bolter is displaced, the operation of the bolter is affected by the unevenness of the underground mine road surface and is very likely to collide with the support column of the support system. Therefore, after the collision, the mining roof will tilt and fall off, thereby reducing the stability of the support system and the mining bolter when they are arranged at the same time; At the same time, the operation difficulty of the anchor bolter will be increased due to the influence of the underground mine road surface. The vibration caused by the rotary drilling will be integrated with the vibration during displacement, which will cause the drilling center position to shift, and eventually cause the drill to be stuck in the rock formation, which will reduce the overall stability of the anchor bolter.

[0015] As a further improvement of the present invention, the disassembly block has a thread pattern on the outside, the balance block and the rubber block are perpendicular to each other and the surface of the contact end is in a polished flat shape, and the center block is in a solid raised shape.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is based on adding a parallel auxiliary structure to the support system, and limits the operating main unit and displacement end position of the anchor machine to the center of the parallel slide, so that it can avoid the influence of the uneven underground mine road surface and reduce its own mobile drilling stability through the cooperation of the parallel slide, and at the same time avoid the collision caused by contact with the inner side of the support rod. When the operating main unit moves, it can drive the driving wheels on the left and right sides of the parallel slide to rotate, thereby improving the smoothness of movement, and then the vertical connection structure on the top can contact the center of the lower layer of the top plate body through the support rod and the pulley, further improving the stability of the linear displacement, thereby improving the stability of the coordinated operation of the support system and the anchor machine.

[0017] 2. The present invention is based on the positioning blocks installed on the left and right sides of the limit frame and the restraint block. The solid block of the positioning block and the insertion rod form a "T" shape, and then the insertion rod carries the movable block on the edge and inserts it into the cross block. Then, the extrusion and rebound effect of the central elastic member of the insertion rod can make the movable block rebound to the inner wall area of ​​the cross block to form a restraining and reinforcement effect, further improving the vertical stability effect of the cross block and the support rod. Then, the movable block can allow the insertion rod to be directly pulled out from the cross block area through the triangular trapezoidal shape, thereby achieving the effect of easy disassembly and assembly.

[0018] 3. The present invention is a further improvement of the protective cover with a vertical connection structure. The four sets of driving modules in the cover can enable the operating host to control the folding part, so that the folding part extends to drive the reinforcement block to insert into the inner edge of the operating host, and then the reinforcement block can move linearly through the center block to prevent it from tilting and getting stuck. The insulating properties of the rubber block are then used to clamp the contact end with the edge of the internal component of the operating host, thereby effectively achieving the reinforcement effect of the internal components of the operating host, preventing the strong vibration caused by the rotary drilling operation from affecting the origin positioning of the internal components of the operating host, and ensuring the operating stability of the operating host.
