Description

Technical Field

[0001] The utility model relates to the technical field of chain breakage and connection, in particular to a chain breakage and connection mechanism. Background Art

[0002] The chain is composed of many links connected together. Each link has one or more gears or rollers, which can transmit motion or force through the meshing between the gears or rollers of adjacent links. When the chain breaks, you first need to check the broken part of the chain and determine whether the break is complete and other possible damages in the chain. Clean the chains at both ends of the broken part to remove oil, dust and other impurities, and ensure that the chain surface is smooth. Depending on the specific situation of the chain break, welding, jointing or repair welding can be used for repair. Among them, welding is a commonly used repair method. The broken parts are welded together to form a complete chain link. The joint is to connect a new section of chain to the broken chain through a connector. , forming a joint, repair welding means coating welding materials on the broken part of the chain to fill the broken gap, form the repair welding part and restore the chain connection. After the repair is completed, the repaired chain needs to be thoroughly inspected to ensure that the repaired chain can withstand normal working conditions and loads, and ensure the strength and reliability of the chain connection. During the use of the repaired chain, care should be taken to avoid external impact, wear or other damage again. Regularly check the use of the chain, and perform maintenance and maintenance in time to ensure the normal service life of the chain. It should be noted that the repair of the chain should be carried out by personnel with relevant experience and professional knowledge, and follow the relevant safety operation specifications and standards to ensure the safety and effectiveness of the repair operation.

[0003] Chain breakage and reconnection refers to the situation in which a chain breaks due to external force, wear or other reasons during its use, and needs to be repaired or jointed so that it can return to normal working condition. Generally, chain breakage requires welding, which is cumbersome and affects the work progress. The chain is worn out due to long-term use, causing the chain to break accidentally during use. The chain is not strong enough, and it is not convenient to disassemble and weld it after it breaks.

[0004] In view of this, we propose a chain breakage reconnection mechanism. Utility Model Content
