[0002] Scraper conveyors are often used as important equipment for tunneling openings because of their easy installation and use. They are widely used underground in coal mines. During the tunneling process, the scraper chute and chain need to be frequently extended as the working face advances. When extending the scraper chain, a momentary scraper machine is used, and workers use their hands to catch it. If they are not careful, they can easily get injured.
[0003] After searching, the existing Chinese patent publication number is CN220448787U. The utility model provides a chain clamping device for extending the chain of a scraper conveyor. The chain clamping device is used to fix the two chains of the scraper conveyor. The chain clamping device is arranged in the transition groove of the scraper conveyor and cooperates with the two chain pressure blocks located on the inner walls of both sides of the transition groove. The chain clamping device includes a connecting piece and two chain clamps. By arranging the chain clamps at both ends of the connecting piece, the chain clamps have a connecting part and a clamping part. By fixing the connecting part on the chain, the clamping part is clamped with the chain pressure block, thereby fixing the two chains of the scraper conveyor in parallel. When the chain is extended on the slope, flying chains are avoided to injure people, which is beneficial to chain extension. When using the chain clamping safety device for extending the chain of the scraper conveyor to extend the chain, only one person is required to operate, avoiding safety accidents caused by improper cooperation of multiple operators and unclear signals.
