Description

Technical Field

[0001] This utility model relates to the field of coal mining, and in particular to a continuous support device for drilling and anchoring in tunneling faces. Background Technology

[0002] The underground tunneling face in a coal mine is the "front line" of mining. Roadways are created through mechanical or manual excavation, paving the way for subsequent coal mining and transportation. However, during tunneling, the surrounding rock is prone to deformation, breakage, and even collapse due to the disruption of the original geological stress balance. The core function of support work is to constrain or support the surrounding rock using support materials such as anchor bolts, anchor cables, and metal supports to prevent collapse.

[0003] A search of Chinese patents revealed an integrated drilling and anchoring guide rail type anchor drill (publication number CN2906020Y). The drill includes a guide rail pusher frame, a support cylinder, and a pusher cylinder. The guide rail pusher frame has a support base at its top. A motor is mounted on the guide rail pusher frame slide, and a traction steel wire rope is fixed to the motor. The other end of the traction steel wire rope passes over a movable pulley at the top of the pusher cylinder and is fixed downwards to the guide rail pusher frame. A drill rod is mounted on the motor shaft, and a drill bit is mounted at the head of the drill rod. An upper end plate is provided on the upper part of the guide rail pusher frame, and a guide device with a guide hole is provided on the upper end plate. The guide device is movably connected to the upper end plate. When drilling anchor bolt holes, the guide device is opened to guide the drill rod using the guide hole. After drilling the anchor bolt holes, when it is necessary to stir the resin and tighten the nut, the guide device with the guide hole can be folded or inserted into the guide rail pusher frame, leaving enough space for the anchor bolt nut and tightening device to pass through. This allows the drill to complete the drilling, resin stirring, and nut tightening operations in a single positioning operation.

[0004] Existing support devices are not convenient for angle adjustment. During support, anchor bolts at different angles need to be driven in according to the support requirements. Generally, when adjusting the angle of the support device, multiple bolts need to be removed, adjusted, and then the bolts are installed to fix the angle. This increases the workload, reduces the efficiency of adjustment, and is inconvenient to use. In order to solve the above problems, we propose a continuous support device for tunneling faces that integrates drilling and anchoring. Utility Model Content

[0005] The purpose of this invention is to provide a continuous support device for drilling and anchoring in tunneling faces, which has the advantage of being easy to adjust the angle.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a continuous support device for drilling and anchoring in a tunneling face, comprising a base, a support and fixing mechanism at the bottom of the base, a sliding groove on the surface of the fixing plate, a sliding plate slidably connected between the inner walls of the sliding groove, a screw threadedly connected to the inner wall of the sliding plate, and both ends of the screw rotatably sleeved with the inner wall of the base, a support rod hinged to the top of the sliding plate, a drilling and anchoring mechanism at the other end of the support rod, a fixing shell bolted to the surface of the base, a worm gear rotatably sleeved between the inner walls of the fixing shell, a worm wheel meshing on the surface of the worm gear, and the axis of the worm wheel being fixedly sleeved by one end of the screw.

[0007] By adopting the above technical solution, the worm gear drives the worm wheel to rotate by rotating the turntable. The rotation of the worm wheel drives the screw to move the slide plate. The movement of the slide plate drives the support rod to rotate the support plate. This method of changing the angle of the drill box that integrates drilling and anchoring can achieve the purpose of easy angle adjustment, reduce workload, improve adjustment efficiency, and save more effort when using worm gear and worm wheel for adjustment.

[0018] The present invention is further configured such that the surface of the base is printed with scale lines.

[0019] By adopting the above technical solution, the angle can be easily adjusted by setting scale lines.

[0020] The present invention is further configured such that: a sliding rod is slidably sleeved on the inner wall of the sliding plate, and both ends of the sliding rod are bolted to the inner wall of the sliding groove.

This utility model uses a rotating turntable to drive a worm gear to rotate, which in turn drives a screw to move a sliding plate. The movement of the sliding plate then drives a support rod to rotate a support plate, thus changing the angle of the integrated drilling and anchoring box. This method facilitates angle adjustment, reduces workload, and improves adjustment efficiency. Using a worm gear and worm wheel makes adjustment more labor-saving. 2. This utility model, after adjustment, rotates the fixing bolt to make the toothed plate and gear mesh tightly, which can fix the worm and prevent the worm wheel from rotating, thereby ensuring the angular stability of the integrated drill box, ensuring the accuracy of the drill and anchor, improving practicality, and making it convenient to use.

The rotation of the turntable 28 drives the worm 9 to rotate, the rotation of the worm 9 drives the worm wheel 10 to rotate, the rotation of the worm wheel 10 drives the screw 5 to rotate, the rotation of the screw 5 drives the slide plate 4 to move, the movement of the slide plate 4 drives the support rod 6 to move, and the movement of the support rod 6 causes the slide block 21 to drive the drill-anchor integrated drill box 25 to rotate, thereby changing the angle of the drill-anchor integrated drill box 25, so as to facilitate the adjustment of the angle. After adjusting the angle, rotate the fixing bolt 13 to tighten the fixing bolt 13, so that the tooth plate 12 and the gear 14 are pressed and meshed, and the worm 9 is fixed to prevent loosening.
