Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to a novel anchor cable support structure for mining. Background Technology

[0002] Anchor cable support is one of the main support methods for surrounding rock in deep roadways, chambers, tunnels, etc. With the emergence of high-strength steel and steel wire and the development of drilling and anchoring technology, anchor cable technology has developed rapidly and has become the preferred measure for reinforcement and strengthening of underground engineering.

[0003] When installing anchor cable support, it is necessary to temporarily cast piers and place steel plates of appropriate anchor cable size at the installation location in the ore body in order to fix the anchor cable to the ore body. Casting piers and customizing suitable steel plates takes a long time, which greatly affects the installation efficiency of anchor cables. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel anchor cable support structure for mining.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel anchor cable support structure for mining includes an ore body with anchor holes. A fixing plate is positioned corresponding to the anchor holes on the ore body. A placement groove is formed in the middle of the fixing plate. Movable blocks are located at both ends of the top of the fixing plate. Sliding grooves are formed on both sides of the top of the fixing plate. The bottom of each movable block is movably installed in a sliding groove. A steel pad is fixedly installed on the inner wall of each movable block. An anchor plate is located in the middle of the fixing plate. A grouting pipe is fixedly installed in the middle of the anchor plate. A coil of steel strand is arranged around the outside of the grouting pipe and is also fixedly installed on the anchor plate. A pointed cone is located at the bottom of each anchor hole. The bottoms of the steel strand and the grouting pipe are fixedly connected to the pointed cone.

[0007] As a further embodiment of this utility model, connecting blocks are fixedly installed on both sides of the movable block, and a locking block is movably installed above the connecting block. The bottom of the locking block extends through the connecting block to the top of the fixed plate, and a locking groove is opened on the top of the fixed plate corresponding to the position of the locking block. The bottom of the locking block can be engaged in the locking groove.

[0008] As a further embodiment of this utility model, threaded nails are movably installed on both sides of the fixing plate, and a fixing bolt is fixedly installed on the ore body at the position corresponding to the threaded nails. The threaded nails can be threadedly connected to the fixing bolts, and an expansion plate is fixedly installed on the outside of the fixing bolts.

[0009] As a further embodiment of this utility model, the bottom of the grouting pipe is connected to the top of the cone, and a grout outlet groove is provided on the side wall of the cone.

[0010] As a further embodiment of this utility model, a tension spring is fixedly installed between the top of the card block and the connecting block.

[0011] As a further embodiment of this utility model, the side of the steel pad is semi-circular.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the position of the fixing bolts on both sides is determined by the position of the threaded nails on the fixing plate. Then, the fixing bolts are driven into the ore body, and the fixing plate is placed on the anchor hole. The threaded nails are then fixed into the fixing bolts, which quickly fixes the fixing plate to the ore body. The fixing plate can replace the pier pad. At the same time, by pulling the locking block out of the locking slot, the movable block can drive the steel pad plate to move. The position of the steel pad plate can be adjusted according to the size of the anchor plate on the steel strand, so that the steel pad plate is locked under the anchor plate, which can limit the anchor plate and fix anchor plates of different sizes. This achieves the effect of eliminating the need for casting pier pads and customizing suitable steel pad plates, and avoids affecting the installation efficiency of the anchor cable.

Then, the fixing bolts 10 are driven into the ore body 1. The expansion plates 16 on both sides of the fixing bolts 10 can increase the resistance, making the fixing bolts 10 more firmly fixed. Then, the fixing plate 3 is placed on the anchor hole 2. By fixing the threaded nails 17 into the fixing bolts 10, the fixing plate 3 can be quickly fixed to the ore body 1. Then, the connecting cone is... The steel strand 7 of the 9 is placed through the placement groove 19 to the bottom of the anchor hole 2. Then, the locking block 12 is pulled out from the locking groove 14, causing the movable block 4 to move the steel pad 5 towards the center. The position of the steel pad 5 is moved according to the size of the anchor plate 6 on the steel strand 7, so that the steel pad 5 can be locked under the anchor plate 6, preventing the anchor plate 6 from moving into the anchor hole 2. This achieves the goal of fixing anchor cables of different sizes. Then, cement grout is injected into the cone 9 through the grouting pipe 8. The cement grout will flow to the bottom of the anchor hole 2 through the grout outlet groove 18 on the cone 9. The cement grout fills the anchor hole 2 from the bottom, which can prevent voids from appearing after the cement in the anchor hole 2 solidifies, thus reducing the strength of the anchor cable support structure.
