Steel wire strand manufacturer: Coal mine roadway support is a crucial aspect of the production process, directly related to the safety of underground workers. It's also a key factor in enabling coal mines to produce more coal, increase output, and reduce roadway maintenance workload and costs. Mine rock bolts, as a type of underground roadway support, are a newly adopted support material in recent years. Its advantages include simple structure, low cost, and durability. However, traditional mine rock bolts, especially during daily maintenance, do not exhibit high safety performance.

Steel wire strand manufacturer: After a period of use, signs of loosening may appear, resulting in poor operational performance. This necessitates improvements to the rock bolts to enhance their safety in mining equipment. Therefore, it is necessary to design a new type of mine rock bolt.

Steel wire strand manufacturer: The mine rock bolt includes a free section and an anchor section. One end of the free section is connected to the anchor section. An isolation groove is provided at the connection between the two. A pressure sensor is provided at the front end of the anchor section. A diamond device is installed in the middle of the pressure sensor. An anchoring body is provided in the anchoring section. A pressure buffer is provided in the anchoring body. Multiple rotating bodies are provided on the outer side of the free section. A row of circular holes is provided on the free section. The slurry passage and buffer plate are provided on the inner side of the free section. The slurry passage is connected to the buffer plate, and water pipes are connected to both sides of the slurry passage.

Steel wire strand manufacturer: The other end of the free section is connected to the anchor through a bracket. An empty groove is provided at the connection between the bracket and the anchor. Two through-holes are provided on the empty groove. Multiple steel wire strands are connected to the outer side of the anchor. Rotating threads are provided in the anchoring section. The inward-facing positions on both sides of the free section are fixed with baffles, and the outward-facing positions at both ends of the free section are provided with sheaths. The main body of the anchoring member and the inner wall of the anchoring member part are connected by a spring device. The ends of several steel wire strands are fixed with a pull ring.

Steel wire strand manufacturer: Compared with the existing technology, the beneficial effects of this utility model are: greatly improved safety performance, greatly improved operability, further optimized performance, and the rock bolt itself can be maintained daily, well meeting the mining requirements. During use, the diamond device is used to clean some hard substances at the fixed position, which is conducive to the smooth insertion of the anchoring section. When the free section and the anchoring section are fixed in the designated position, they can rotate freely to facilitate adjustment of their placement, preventing friction with surrounding objects and enhancing their self-protection ability. Slurry and clean water can be injected through the two through-holes in the empty groove, the slurry is transported through the slurry passage, clean water is stored in the water pipes, and the circular holes are used for drainage during daily maintenance. The free section is protected from corrosion by acidic substances covering it. The fixed position is bound by steel wire strands to expand the fixed area. When vibration occurs, the spring device and pressure buffer buffer the vibration pressure. The buffer plate protects the slurry passage and water pipes from damage. It has a long service life, novel design, and is worth promoting.
