Description

Technical Field

[0001] This utility model relates to the field of light steel support technology, specifically a lightweight steel arch support structure for mines. Background Technology

[0002] In the mining process, roadway support is a key link in ensuring safe production. Traditional support structures often use heavy I-beams or U-shaped steel arch frames. Although they have strong load-bearing capacity, they have disadvantages such as large weight, difficulty in transportation and installation, high labor intensity, and high support costs. Especially in areas with complex geological conditions and large variations in roadway cross-section, heavy arch frames have poor adaptability and low installation efficiency. Therefore, there is a need for a mine roadway support structure that is lightweight, easy to transport, and easy to install. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a lightweight steel arch support structure for mines, which has the advantages of being lightweight, easy to install, and easy to transport.

[0007] An arc-shaped cylinder is placed above the support cylinder. Each support cylinder and arc-shaped cylinder has a connecting flange fixedly installed at both ends, and the connecting flanges are fixedly connected by bolts. A connecting seat is fixedly installed on the outer side of each arc-shaped cylinder. Each connecting seat has slots arranged at equal intervals at its top. A square light steel is placed inside each slot, and a connecting block is placed between the square light steel. Insert blocks are fixedly installed at both ends of each connecting block, and the insert blocks extend into the interior of the square light steel. Two elastic clips are fixedly installed on the outer side of each insert block.

[0008] Furthermore, the upper surface of the base plate is fixedly connected to the support cylinder by multiple bolts, and multiple mounting holes are provided at the edge of the base plate.

[0009] By adopting the above technical solution, the structure can be installed more effectively using anchor bolts and mounting holes.

[0010] Furthermore, a pressure plate is fixedly installed on top of each of the connecting seats by bolts.

[0011] By adopting the above technical solution, the square light steel can be better fixed and installed.

[0012] Furthermore, both the support cylinder and the arc-shaped cylinder are made of rectangular hollow light steel, and the support cylinder and the arc-shaped cylinder are equipped with reinforcing ribs, and the arc-shaped cylinder is made of light cold-formed steel.

[0013] By adopting the above technical solutions, the problem of difficult transportation in the roadway can be better solved through assembly. Furthermore, the hollow and lightweight design facilitates transportation and assembly, and the internal reinforcing ribs can better improve the support effect.

[0014] (III) Beneficial Effects

[0015] Compared with existing technologies, the lightweight steel arch support structure for this mine has the following advantages:

[0016] This utility model, by incorporating a support cylinder and an arc-shaped cylinder, and connecting and fixing them with a connecting flange, makes material handling in tunnels more convenient and faster. Furthermore, the assembly method allows for more flexible installation and use. The square light steel at the top allows for better laying of metal mesh, providing better protection for the top and preventing falling debris from threatening the tunnel or workers. The inclusion of inserts and elastic clips allows for better connection between adjacent square light steel sections. The elastic clips deform when pushed into the square light steel sections, generating a rebound force that securely and quickly connects the sections. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a lightweight steel arch support structure for mines, including a base plate 2. The upper surface of the base plate 2 is fixedly connected to the support cylinder 1 by multiple bolts. Multiple mounting holes 6 are provided at the edge of the base plate 2 to better install the structure through anchor rods and mounting holes 6.

[0025] A positioning block 7 is fixedly installed on the upper surface of each base plate 2, and two support cylinders 1 are placed on the top of each base plate 2, with the lower support cylinder 1 inserted into the outside of the positioning block 7.

[0026] An arc-shaped cylinder 4 is placed above the support cylinder 1. Both the support cylinder 1 and the arc-shaped cylinder 4 are made of rectangular hollow light steel, and the support cylinder 1 and the arc-shaped cylinder 4 are equipped with reinforcing ribs. The arc-shaped cylinder 4 is made of lightweight cold-formed steel, which can better solve the problem of difficult transportation in the roadway through assembly. The hollow and lightweight design makes transportation and assembly easier, and the internal reinforcing ribs can better improve the support effect.

[0027] Each support cylinder 1 and arc-shaped cylinder 4 has a connecting flange 5 fixedly installed at both ends, and the connecting flanges 5 are fixedly connected by bolts. Each arc-shaped cylinder 4 has a connecting seat 8 fixedly installed on its outer side, and a pressure plate 10 is fixedly installed on the top of each connecting seat 8 by bolts to better fix the square light steel 3. Each connecting seat 8 has a slot 9 arranged at equal intervals at its top, and a square light steel 3 is placed inside each slot 9. A connecting block 12 is placed between the square light steel 3. Insert blocks 13 are fixedly installed at both ends of the connecting block 12, and the insert blocks 13 extend into the interior of the square light steel 3.
