Description

Technical Field

[0001] This utility model belongs to the field of coal mining, and in particular relates to a diamond-shaped mesh. Background Technology

[0002] Coal mines are an important energy source in my country. They are often located underground at great depths. To ensure safety, diamond mesh needs to be laid at the mining face. However, the lifespan of diamond mesh after anchoring and spraying is affected. In particular, when mining in layers, the diamond mesh used as a false roof is subject to water erosion. Ordinary galvanized iron wire mesh will gradually rust, continuously reducing the support strength and thus affecting safety. Utility Model Content

[0003] The purpose of this invention is to provide a diamond-shaped mesh to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A diamond mesh includes a diamond mesh body and a protective frame. The protective frame is installed around the outer periphery of the diamond mesh body. One protective frame and one diamond mesh body form a set of diamond mesh. In use, multiple sets of diamond mesh can be combined into a whole. Multiple support rods span the top of the diamond mesh body. The support rods are located on both sides of the diamond mesh body, and the two ends of the support rods are connected to the protective frame. Two adjacent diamond mesh bodies are connected by the support rods.

[0006] Preferably, the diamond mesh body is made of galvanized iron wire, and the outer side of the diamond mesh body is coated with protective glue, which covers the diamond mesh body.

[0007] Preferably, a circular hole is provided on one side of the protective frame, and the support rod is located at one end of the circular hole and is fixed by a fastening screw passing through the circular hole.

[0008] Preferably, the support rod is designed as a long, inverted gantry frame. The support rod includes a plate, a notch, a mounting groove, a support block, and an extension plate. The plate has a notch, and the upper and lower ends of the plate have mounting grooves. The mounting grooves contain support blocks for screw mounting, and the side of the support block away from the plate has an enlarged area design. The inner wall of the notch has multiple grooves, and the plate has threaded fastening screws located at the opening of the notch. The two ends of the plate have integrally formed extension plates with screw holes for the connecting screws to pass through. The extension plates at both ends are staggered.

[0009] Preferably, the support block is made of zinc.

[0010] Compared with the prior art, this utility model has the following advantages: the design of this utility model is reasonable; the protective frame can wrap and protect the diamond mesh body from all sides, thereby improving the integrity of the diamond mesh body; the support rods on the diamond mesh body reduce the contact between the diamond mesh body and water, thereby reducing the corrosion of the diamond mesh body. At the same time, the support rods can protect and support the diamond mesh body and the protective frame, improving the strength of the diamond mesh body; the grooves on the plate increase the friction between the plate and the diamond mesh body; and the mounting groove facilitates the installation and positioning of the support block.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1-3 As shown, a diamond-shaped mesh includes a diamond-shaped mesh body 1 and a protective frame 2. The protective frame 2 is installed on the outer periphery of the diamond-shaped mesh body 1. One protective frame 2 and one diamond-shaped mesh body 1 form a set of diamond-shaped mesh. In use, multiple sets of diamond-shaped meshes can be combined into a whole. Multiple support rods 3 span the top of the diamond-shaped mesh body 1. The support rods 3 are located on both sides of the diamond-shaped mesh body 1, and both ends of the support rods 3 are connected to the protective frame 2. Two adjacent diamond-shaped mesh bodies 1 are connected by the support rods 3. The diamond-shaped mesh body 1 is made of galvanized iron wire. The outer side of the diamond-shaped mesh body 1 is sprayed with protective glue, which covers the diamond-shaped mesh body 1. A round hole 4 is opened on one side of the protective frame 2. The support rod 3 is located at one end of the round hole 4 and is fixed by fastening screws 10 passing through the round hole 4. The support rod 3 has a long strip-shaped inverted gantry design and includes a plate 6. The plate body 6 has a notch 7, a mounting groove 8, a support block 9, and an extension plate 12. The plate body 6 has a notch 7, and the upper and lower ends of the plate body 6 have mounting grooves 8. The mounting grooves 8 contain support blocks 9 for screw mounting. The side of the support block 9 away from the plate body 6 has an enlarged area design. The inner wall of the notch 7 has multiple grooves 11. The plate body 6 has threaded fastening screws 10 located at the opening of the notch 7. The plate body 6 has integrally formed extension plates 12 at both ends. The extension plates 12 have screw holes 13 for the connecting screws to pass through. The extension plates 12 at both ends are staggered. The support block 9 is made of zinc material. The activity of the support block is higher than that of the diamond mesh body. When corrosion occurs, the support block is corroded first, thus protecting the diamond mesh body. The support block can be replaced later.

[0016] The working principle of this utility model is as follows: During manufacturing, a diamond mesh body of appropriate size is installed inside the protective frame. After installation, the diamond mesh body is sprayed with adhesive to reduce the contact between the diamond mesh body and water and air, thereby extending its service life. Then, multiple support rods are connected to the diamond mesh body and the protective frame. The plates on the support rods are connected to the round holes on the protective frame by fastening screws. The notches on the plates span across the diamond mesh body and wrap around it. The grooves on the inner wall of the notches on the plates increase the friction. Before installing the plates, the support blocks are connected to the installation grooves. Adjacent diamond mesh bodies are connected and combined using the outer extension plates on both sides of the plates.

[0017] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
