However, the current excavator mainly adopts manual operation in the meshing process, which requires workers to climb to a certain height, hold the anchor net by hand, and manually transfer to complete the whole operation, thus failing to realize automatic meshing. This method requires multiple people to complete, has high labor intensity, low operation efficiency, and seriously threatens the safety of workers.

[0003] In recent years, some related researches have been conducted on automatic meshing technology for coal mine roadway, such as the patent with publication number CN109989779 A, which discloses a temporary support system integrating automatic meshing, dust removal device, and front exploration function, which includes a temporary support mechanism, and an automatic meshing mechanism is arranged on the temporary support mechanism for anchor net storage, transportation, and hanging, which can realize the storage, transportation, and automatic hanging of the anchor net.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1, such as Figure 1 , Figure 2As shown, the intelligent roadway support system with automatic mesh laying function comprises a temporary support assembly 1 and an automatic mesh laying assembly 2. The automatic mesh laying assembly 2 comprises a mesh taking mechanism 22, an anchor mesh conveying mechanism 23 and a mesh hanging mechanism 24. The mesh taking mechanism 22 is located at the rear end of the temporary support assembly 1, the mesh hanging mechanism 24 is located at the front end of the temporary support assembly 1, and the anchor mesh conveying mechanism 23 is slidingly arranged on the main frame body 12 of the temporary support assembly 1. Under the action of the longitudinal driving member, the anchor mesh conveying mechanism 23 moves longitudinally along the main frame body 12, thereby adjusting the longitudinal position of the anchor mesh. The mesh taking mechanism 22 takes down the anchor mesh at the rear end of the temporary support assembly 1, and conveys the anchor mesh to the front end of the temporary support assembly 1 through the anchor mesh conveying mechanism 23. Then, the longitudinal relative position of the anchor mesh conveying mechanism 23 and the main frame body 12 is adjusted through the longitudinal driving member, thereby adjusting the longitudinal position of the anchor mesh. Then, the anchor mesh is taken down from the anchor mesh conveying mechanism 23 through the mesh hanging mechanism 24 and installed, realizing the mechanization and automation of the roadway heading machine mesh laying operation, improving the roadway support operation efficiency, reducing the labor intensity of workers, and facilitating flexible adjustment of the anchor mesh position for installation.

[0029] Further, as shown in the drawings, Figure 5 The mesh taking mechanism 22 comprises a guide rail 223 fixed on the main frame body 12 and a mesh taking oil cylinder 221. A sliding block 222 is slidingly connected to the guide rail 223, and the sliding block 222 is connected to the mesh taking oil cylinder 221. A connecting rod 224 is arranged on the sliding block 222, and a mesh hook 225 for taking mesh is arranged on the connecting rod 224. Specifically, the guide rail 223 and the mesh taking oil cylinder 221 are located on the outside of the main frame body 12 and at the rear end of the main frame body 12. The mesh taking oil cylinder 221 can drive the sliding block 222 to slide on the guide rail 223, thereby moving the mesh hook 225 through the connecting rod 224. When the mesh taking oil cylinder 221 is extended, the sliding block 222 moves the mesh hook 225 backward to the mesh storage area on the anchor mesh storage 21. After the mesh hook 225 hooks the anchor mesh, the mesh taking oil cylinder 221 is retracted, and the mesh hook 225 pulls out the anchor mesh, realizing the automation of taking out the anchor mesh.

When the mesh taking oil cylinder 221 is extended, the side of the inclined surface of the mesh hook 225 first contacts the anchor mesh, and under the action of the inclined surface, the mesh hook 225 rotates. After the mesh hook 225 passes over the transverse rib of the anchor mesh, the mesh hook 225 returns to the original position under the action of its own gravity. When the mesh taking oil cylinder 221 is retracted, the vertical surface of the mesh hook 225 contacts the transverse rib of the anchor mesh, and the mesh hook does not rotate due to the action of the limiting block.
