Technical Field

[0001] This utility model relates to the field of roadway support technology, specifically to a coal mine roadway support component. Background Technology

[0002] Coal mine roadways are a general term for shafts, tunnels, and chambers excavated during underground coal mining for purposes such as hoisting, transportation, ventilation, and drainage. Coal mine roadways are gradually excavated by specialized tunneling machines. Support structures are usually built on the inner walls of the excavated coal mine roadways to support them and ensure that the coal mine roadways do not collapse.

[0003] The existing coal mine roadway support structure mainly adopts the steel support method. The steel support method uses steel supports as the support structure. Steel supports have strong support capacity and good stability, and are suitable for roadways under medium and hard surrounding rock conditions. During the laying and assembly of existing steel supports in the roadway, a layer of wire mesh needs to be laid on the roadway surface. However, wire mesh has strong toughness, and it is difficult to lay wire mesh on the roadway surface manually. The laying work is time-consuming, labor-intensive, and very dangerous. Utility Model Content

[0004] The purpose of this invention is to provide a coal mine roadway support component to solve the aforementioned problems in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A coal mine roadway support component includes a horizontal steel plate, with vertical steel plates at the bottom of both ends of the horizontal steel plate, a support plate placed on the top of the horizontal steel plate, and a wire mesh laid on the top of the support plate, with both ends of the wire mesh extending to the sidewalls of the vertical steel plate.

[0007] Preferably, the top four corners of the pallet are provided with protruding nails, the extended ends of the protruding nails extend upward and penetrate the wire mesh, the outside of the wire mesh is a rectangular channel, the outer surface of the wire mesh is in close contact with the inner wall of the rectangular channel, and the top of the protruding nails can be inserted into the rectangular channel.

[0008] Preferably, the top of the tray has four through holes, each of which is provided with a pin, which extends upward and penetrates the tray and the wire mesh.

[0009] Preferably, the bottom center of the insert has a threaded groove.

[0010] Preferably, the bottom of the transverse steel plate is provided with multiple sockets, and a steel pipe is inserted into each socket.

[0011] Preferably, the inner wall of the vertical steel plate is provided with a support base, and a bracket is provided on one side of the support base. The bracket includes a crossbar, and a plurality of claws are provided on the top of the crossbar. Both ends of the crossbar are provided with locking blocks. The top of the support base is provided with a locking groove, and the locking blocks and the locking groove cooperate with each other. The front surface of the support base is provided with a fixing plate, and the fixing plate and the locking groove are fixedly connected by bolts.

[0012] Preferably, the surface of the vertical steel plate is provided with grooves.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By using a set pallet, the wire mesh is laid flat on the surface of the rectangular tunnel by placing the wire mesh on top of the pallet, then lifting both ends of the pallet and pressing them tightly against the top of the inner wall of the tunnel. This laying process is simple and facilitates rapid wire mesh laying. Furthermore, under the compression and support of the pallet, the wire mesh can fit more smoothly against the surface of the rectangular tunnel, effectively improving the laying quality of the wire mesh.

The two ends of the wire mesh 2 extend to the side wall of the vertical steel plate 3.

[0028] In this embodiment, by laying wire mesh 2 on the surface of the rectangular roadway 1, the wire mesh 2 effectively fixes the rock strata due to its high strength and corrosion resistance, preventing rock collapse caused by changes in underground pressure. The wire mesh 2 can protect miners from falling rocks and other objects, thereby improving the safety of the mine. The wire mesh 2 is malleable, and under the multiple support and compression of the horizontal steel plate 5, the vertical steel plate 3, and the support plate 4, the wire mesh 2 adheres to the surface of the rectangular roadway 1, which can provide better support for the rectangular roadway 1.

[0029] like Figure 1 and Figure 7 As shown, protruding nails 8 are provided at the four corners of the top of the pallet 4. The extended ends of the protruding nails 8 extend upward and penetrate the wire mesh 2. The outside of the wire mesh 2 is a rectangular channel 1. The outer surface of the wire mesh 2 is tightly attached to the inner wall of the rectangular channel 1. The top of the protruding nails 8 can be inserted into the rectangular channel 1. During the process of laying the wire mesh 2 on the top of the pallet 4, the edge of the wire mesh 2 is aligned with the edge of the pallet 4. After alignment, the protruding nails 8 penetrate the wire mesh 2 upward, so that the position of the wire mesh 2 is fixed and will not be misaligned, so that the pallet 4 can press the wire mesh 2 upward and press the wire mesh 2 onto the surface of the rectangular channel 1.

[0030] like Figure 1 , Figure 7 and Figure 8As shown, the top of the pallet 4 has four through holes, and each through hole is equipped with a nail 9. After the pallet 4 is laid on the inner wall of the rectangular tunnel 1, the nail 9 is inserted upward through the pallet 4 and the wire mesh 2, and the top extension of the nail 9 is inserted into the rectangular tunnel 1. The nail 9 can be used to fix the pallet 4 and the wire mesh 2 to the surface of the rectangular tunnel 1. After fixing, the horizontal steel plate 5 and the vertical steel plate 3 are used for support.

[0031] The bottom center of the pin 9 has a threaded groove 13; during the process of disassembling the support plate 4, the bolt is screwed into the threaded groove 13 from the bottom of the support plate 4 in a threaded manner, and then the bolt is pulled down to pull the pin 9 out downwards, so as to remove the support plate 4.

[0032] like Figure 1 - Figure 3 As shown, multiple sockets 6 are provided at the bottom of the horizontal steel plate 5, and a steel pipe 7 is inserted into each socket 6;

[0033] The inner wall of the vertical steel plate 3 is provided with a support base 11. A bracket 10 is provided on one side of the support base 11. The bracket 10 includes a crossbar. Multiple claws 101 are provided on the top of the crossbar. Locking blocks 102 are provided at the bottom of both ends of the crossbar. A slot 104 is provided on the top of the support base 11. The locking blocks 102 and the slot 104 cooperate with each other. A fixing plate 103 is provided on the front surface of the support base 11. The fixing plate 103 and the slot 104 are fixedly connected by bolts.

[0034] In the rectangular tunnel 1, the support components are laid. First, wire mesh 2 is laid, and then horizontal steel plates 5 and vertical steel plates 3 are installed. After laying two wire meshes 2, a support plate 4 is set at the bottom of each wire mesh 2. A horizontal steel plate 5 is set at the bottom of the support plate 4, and vertical steel plates 3 are set at the bottom of both ends of the horizontal steel plate 5. The bottom of the vertical steel plate 3 is located on the ground of the rectangular tunnel 1. The center lines of the sockets 6 at the bottom of two adjacent horizontal steel plates 5 are on the same straight line. Then, a steel pipe 7 is inserted into the socket 6 to support the two horizontal steel plates 5. At the same time, a bracket 10 is used to support the bottom of the steel pipe 7. The two ends of the crossbar of the bracket 10 are placed in the slots 104 respectively, and the locking block 102 at the bottom of the crossbar is wrapped with a fixing plate 103. Finally, the fixing plate 103 and the support seat 11 are fixed with bolts to ensure that the locking block 102 will not detach from the support seat 11, which is conducive to the bracket 10 stably supporting the steel pipe 7.

[0035] like Figure 6 As shown, the surface of the vertical steel plate 3 is provided with a groove 12. By setting the groove 12 on the surface of the vertical steel plate 3, it is beneficial to save materials, reduce the weight of the support structure, facilitate manual handling of the vertical steel plate 3, and facilitate installation.
