Description

Technical Field

[0001] The utility model relates to the technical field of mining accessories, and more specifically, to a flat connecting link for a high-strength round link chain for mining. Background Art

[0002] Connecting links are detachable links that connect the links of the anchor chain. Flat connecting links are used to connect the scraper chains in various scraper conveyors. They come in serrated, ladder, and curved tooth styles. Sawtooth connecting links are difficult to assemble and disassemble, while ladder tooth connecting links are easier to assemble and disassemble, but the tooth shape is subject to change. Curved tooth connecting links have an arc-shaped mating surface, which improves the stress state of the tooth surface, resulting in high strength, reliable connection, and easy assembly and disassembly. Therefore, this type of connecting link is gradually replacing serrated and ladder tooth connecting links.

[0003] The flat connecting links used in the current common mining high-strength round link chains generally have a relatively simple structure. If the strength of the connecting links cannot be guaranteed, the connecting links may break, causing the link structure to be disconnected, thereby affecting people's use and leading to danger.

[0004] After searching, the Chinese patent with the announcement number CN213393356U discloses a flat connecting link for a mining round link chain. The provided clamping structure can effectively provide a more stable connection. The provided wear-resistant structure can effectively reduce the damage caused by friction of the connecting link structure. The provided wear-resistant structure makes it possible for people to not replace the entire connecting link structure when the connecting link is worn due to long-term use. The provided connection structure allows people to conveniently and quickly assemble and disassemble the connecting link.

[0005] When the flat connecting links for the above-mentioned mining round link chains are actually used, the flat connecting links will be difficult to disassemble after being used for a long time. When the round link chain or related parts need to be repaired or replaced, the operation difficulty of the maintenance personnel will be increased, and more tools, more complicated steps and longer time will be required to complete the disassembly work, thereby reducing.

[0012] By adopting the above technical solution: the first gear is used to drive the second gear to rotate, so that the convex teeth between the first gear and the second gear can limit the rotation position of the rotating rod.

[0013] As a further description of the above technical solution: two connecting slot rods are fixedly connected to one side of the first circular link chain, and a plurality of slots are provided on the lower surface of the connecting slot rods. A second circular link chain is provided on one side of the first circular link chain, and a clamping mechanism is provided on one side of the second circular link chain.
