Metal mesh pressing assemblies 3 are provided on both sides of the support plate 13. The metal mesh pressing assembly 3 includes a fixed plate 31, a pressing plate 32, and an adjusting screw 33. The adjusting screw 33 rotates on the outer side of the corresponding end of the support plate 13 through the fixed plate 31 and controls the pressing plate 32 to move laterally at the end of the support plate 13.

[0020] In this embodiment: the support component 1 is installed inside the mine roadway and is used to connect the metal mesh and support the mine roadway from the inside of the mine roadway together with the metal mesh. The support component 1 consists of an upper arched support frame 11, an arched outer frame 12 and a support plate 13. The arched outer frame 12 is fixedly connected to the outer wall of the upper arched support frame 11. There are two support plates 13, which are fixedly connected to the two ends of the arched outer frame 12 respectively. The support plates 13 are fixedly connected to the outer wall of the support component 1 on the side corresponding to the side of the support component 1, so that the two support plates 13 are stably connected to the outer wall of the upper arched support frame 11 through the arched outer frame 12. The upper arched support frame 11, the arched outer frame 12 and the support plates 13 are stably combined, which improves the overall stability of the support component 1. Both the upper arched support frame 11 and the arched outer frame 12 are provided with several anchor holes 14. The anchor holes 14 are used to insert anchor rods into the upper arched support frame 11 and the arched outer frame 12. The upper arched support frame 11 and the arched outer frame 12 are positioned at a designated location in the mine roadway. By inserting anchor rods into the anchor holes 14 in the lower half of the upper arched support frame 11, the anchor rods are fastened to the inside of the mine roadway, which can effectively fix the positioning support component 1 at the designated location in the mine roadway.

[0021] The cable restraint assembly 2 is slidably connected to the inner side of the support assembly 1. The cable restraint assembly 2 consists of a base 21, a top cover 22, and a movable frame 23. The top cover 22 is rotatably connected to the top of the base 21, and its free end is screwed to the base 21. This screwing fixes the top cover 22 to the top of the base 21, facilitating the separation and assembly of the top cover 22 on the top of the base 21. Rotating the top cover 22 upwards exposes the base 21, allowing cables to be inserted into the base 21. Rotating the top cover 22 resets it, and bolts secure the top cover 22 to the top of the base 21, effectively allowing... The cable restraint operation is simple and convenient for cable installation and restraint. The outer wall of the movable frame 23 is fixedly connected to the fixed frame 231, and the other end of the fixed frame 231 is fixedly connected to the base 21, stably connecting the movable frame 23 and the base 21. The movable frame 23 is slidably connected between the upper arched support frame 11 and the arched outer frame 12. The movable frame 23 can move along the arched side of the upper arched support frame 11 between the upper arched support frame 11 and the arched outer frame 12, which facilitates the adjustment of the position of the cable restraint assembly 2 inside the upper arched support frame 11, thereby adjusting the position of the cable inside the upper arched support frame 11.

[0022] A metal mesh clamping assembly 3 is provided on both sides of the tray 13. The metal mesh clamping assembly 3 consists of a fixed plate 31, a clamping plate 32 and an adjusting screw 33. The fixed plate 31 is fixedly connected to the corresponding end of the tray 13. The adjusting screw 33 is screwed into the inside of the fixed plate 31. The clamping plate 32 is rotatably connected to the front end of the adjusting screw 33. The outer side wall of the clamping plate 32 is flush with the outer side of the tray 13. The top of the clamping plate 32 is higher than the top of the tray 13. By rotating the adjusting screw 33, the clamping plate 32 can be moved laterally at the end of the tray 13, which facilitates the position adjustment of the clamping plate 32.

[0023] The support assembly 1 is placed at a designated position in the mine roadway and supports the metal mesh from the inside. Anchor rods are inserted into the anchor holes 14 below the upper arched support frame 11 to secure the upper arched support frame 11 in the mine roadway. The metal mesh can be placed into the space between the arched outer frame 12 and the roadway wall. The metal mesh can be moved along the outer wall of the arched outer frame 12 by the construction workers pulling it from the inside, making it easy to freely adjust the position of the metal mesh. Two support plates 13 support the two ends of the metal mesh. By operating the metal mesh clamping assembly 3, the adjusting screw 33 is rotated to make the clamping plate 32 move laterally and press the metal mesh inward, which can effectively position the metal mesh on the roadway wall. Two sets of adjacent metal meshes can be placed between the arched outer frame 12 and the tunnel wall. The splicing area of ​​the metal meshes corresponds to the anchor holes 14 at the arched position of the upper arched support frame 11. The anchor rods can pass through the anchor holes 14 at the arched position of the upper arched support frame 11 and the anchor holes 14 on the arched outer frame 12, connecting the upper arched support frame 11 and the arched outer frame 12 from the splicing area of ​​the two sets of metal meshes, and are fastened inside the tunnel wall. This can effectively fix the metal mesh and support component 1 as a whole to the tunnel wall, allowing construction personnel to conveniently perform the support positioning and adaptive alignment adjustment of the metal mesh on the tunnel wall, facilitating the splicing and fixing of the two sets of adjacent metal meshes on the tunnel wall, and avoiding gaps in the coverage area of ​​the metal mesh. The cable is placed and fixed between the base 21 and the top cover 22. At the same time, the cable restraint component 2 can move the cable to a designated position inside the upper arch support frame 11, which allows construction personnel to conveniently install and fix the cable inside the metal mesh. The cable does not contact the metal mesh, which can prevent the metal mesh from deforming and detaching due to the pulling of the cable, thus improving the support effect on the mine roadway.
