[0002] In the coal and mining industries, scraper conveyors are key equipment for efficient material transport, and their operating efficiency directly affects the overall production capacity and economic benefits of the mine. The scraper chain, as the core component of the scraper conveyor, plays a crucial role in smoothly and quickly transporting materials from the working face to the designated location, and is widely used in various mining scenarios. Mining chains mainly consist of circular links, connecting rings, nuts, bolts, and pressure plates. Scrapers are fixed to the chain using bolts, nuts, and other accessories, forming the scraper chain, which is used for power transmission and traction guidance.
[0003] Due to the harsh working environment in coal mines, scraper chains operate continuously under high loads, in humid conditions, and with high dust levels, making them highly susceptible to wear and breakage. Currently, the disassembly of mining chains mainly relies on manual operation, which is labor-intensive, inefficient, and unsafe. Traditional chain links are mostly hook-shaped, allowing for easy disassembly when the chain is loose. However, when the chain is taut under heavy loads, the chain and the load must be lifted to loosen them before disassembly. This method is not only time-consuming and laborious but also poses serious safety hazards. Furthermore, the disassembly process requires removing numerous nuts, which are often jammed with coal slurry, necessitating on-site drilling and milling, further reducing disassembly efficiency.
[0004] Therefore, it is necessary to invent an integrated device for quick disassembly and positioning of mining chains to solve the above problems. Utility Model Content

Detailed Implementation
[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] This utility model provides, for example Figure 1-5 The device shown is an integrated quick disassembly and positioning device for mining chains, comprising an integral chain composed of multiple chain units. Each chain unit includes two sets of connecting rods 1 and connectors 2 installed at both ends. Both ends of the two sets of connecting rods 1 are provided with mounting components 3 for positioning and installing the connectors 2. The mounting components 3 are located inside both ends of the connecting rods 1. Specifically, the connecting rod 1 has docking grooves 11 at both ends, and the outer wall of the connecting rod 1 is also provided with a rotating groove 12 that communicates with the docking grooves 11. The mounting assembly 3 is installed in the docking grooves 11 and the rotating groove 12. Specifically, the mounting assembly 3 includes a fastening ring 31, which is installed in the mating groove 11. A rotating ring 32 is installed in the rotating groove 12. The outer walls of the rotating ring 32 and the fastening ring 31 are provided with matching racks 33. Specifically, the connector 2 has positioning blocks 21 extending from both ends of the connector 2 to match the mating grooves 11. The end of the positioning block 21 also has a stud 22 extending from the end of the positioning block 21 to match the inside of the fastening ring 31. The studs 22 at both ends correspond to the fastening rings 31 at both ends. The rotating ring 32 rotates the fastening studs 22 into the fastening ring 31.
[0018] Specifically, the inner wall of the rotating groove 12 is provided with connecting holes 13 on both sides, and the rotating ring 32 is provided with rotating shafts 34 at both ends that match the connecting holes 13. The rotating ring 32 is installed in the rotating groove 12, and the outer wall rack 33 of the rotating ring 32 matches the outer wall rack 33 of the fastening screw ring 31.
[0019] Specifically, a connecting plate 14 extends from the bottom of the docking groove 11, and a positioning rotating ring 15 extends from the outer side of the end of the connecting plate 14. The inner wall of the fastening screw ring 31 is provided with a ring groove 35 that matches the positioning rotating ring 15, and the fastening screw ring 31 rotates outside the positioning rotating ring 15.
[0020] Specifically, the overall size of the positioning block 21 matches the size of the fastening ring 31 after it is installed inside the mating groove 11, and the external thread of the stud 22 matches the internal thread of the fastening ring 31.
[0021] Specifically, the length of the stud 22 matches the length of the internal thread of the fastening ring 31, meaning that both ends of the connector 2 are tightly connected to both ends of the connecting rod 1.
[0022] Specifically, the two connectors 2 are semi-circular in shape.
[0023] In this embodiment, the fastening screw ring 31 is embedded into the mating grooves 11 at both ends of the connecting rod 1, so that the annular groove 35 on the inner wall of the fastening screw ring 31 precisely engages with the positioning rotating ring 15 at the end of the connecting plate 14 at the bottom of the mating groove 11, ensuring that the fastening screw ring 31 can rotate stably around the positioning rotating ring 15 without radial displacement. Then, the rotating ring 32 is installed into the rotating groove 12 on the outer wall of the connecting rod 1, so that the rotating shafts 34 at both ends of the rotating ring 32 are inserted into the connecting holes 13 on the inner wall of the rotating groove 12, while ensuring that the rack 33 on the outer wall of the rotating ring 32 is fully engaged with the rack 33 on the outer wall of the fastening screw ring 31, thus completing the pre-assembly of a single connecting rod 1.
[0024] Specifically, take two pre-assembled connecting rods 1, align the positioning blocks 21 at both ends of the connector 2 with the mating grooves 11 of the connecting rod 1, and insert them. At this time, the size of the positioning blocks 21 perfectly matches the space after the fastening rings 31 are installed in the mating grooves 11, achieving initial positioning. Next, rotate the rotating ring 32 in the rotating groove 12, which drives the fastening rings 31 to rotate synchronously through the rack 33. The internal thread of the fastening rings 31 engages with the studs 22 at the end of the positioning blocks 21. Continue rotating until the studs 22 are fully screwed into the fastening rings 31. At this time, the two ends of the connector 2 are tightly fitted with the two ends of the connecting rod 1, and the assembly of a single chain unit is completed.
[0025] Specifically, the above steps are repeated to assemble multiple chain units, which are then connected to the transmission components of the mining equipment via semi-circular connectors 2 to form a complete mining chain.
[0026] In this embodiment, when the chain unit needs to be disassembled or replaced, the rotating ring 32 is rotated in the opposite direction, which drives the fastening screw ring 31 to rotate in the opposite direction, so that the stud 22 is removed from the fastening screw ring 31, and the connector 2 can be pulled out to separate the two sets of connecting rods 1, thus completing the quick disassembly.
[0027] In this embodiment, the linkage structure of the rotating ring, rack, and fastening ring allows the stud to be screwed in and out simply by rotating the rotating ring, significantly reducing the assembly and disassembly time of a single chain unit. Furthermore, all core components are internally mounted, unaffected by downhole dust or water, avoiding tool jamming and further ensuring efficient operation.
[0028] In this embodiment, the positioning block and the docking groove are size-matched, and the positioning rotating ring and the ring groove are engaged to form a double radial positioning, avoiding connection misalignment; the threads of the stud and the fastening ring are precisely matched and the lengths are adapted to achieve a tight connection, which greatly reduces the risk of loosening during heavy-load operation and improves the stability of chain operation.
[0029] In this embodiment, the standardized chain unit design can be adapted to mining chains of different specifications. The semi-circular connector fits the equipment transmission components, reducing friction interference. The built-in structure has no exposed protrusions, which not only prevents personnel from accidentally touching and getting injured, but also avoids external debris from hitting and damaging the components, making it suitable for harsh underground working environments.
[0030] In this embodiment, the tightly connected structure reduces the frequency of failures, the quick disassembly and assembly design shortens maintenance downtime, and standardized components reduce replacement costs, thereby comprehensively reducing maintenance investment and downtime losses in mine production.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
