Description

Technical Field

[0001] The utility model relates to the technical field of tobacco transportation, in particular to a tool for quickly disassembling and assembling a chain plate. Background Art

[0002] Chain conveyors are widely used in the tobacco industry and logistics and transportation industries, and are mainly used to complete material conveying functions. The cargo conveying chain is composed of chain plates, which are vulnerable parts of the equipment. The chain material is made of hard plastic, and the overall size of the conveying chain is relatively long. When the equipment is running, the load carried by a single chain plate is large. The chain plate is prone to cracking and deformation after long-term operation, which can cause chain breakage, shutdown, jamming, cargo deviation and other faults. Therefore, it is necessary to replace the damaged chain plate in time.

[0003] During replacement, at least two workers are required to compress the chains on both sides of the damaged chain plate toward the damaged chain plate to unload the tension force to prevent the chain plate pin from disengaging due to its own weight and the outward tension of the chain plate when the chain plate pin is removed in the next step. Then one worker removes the chain plate pin, disengages the meshing part of the damaged chain plate, removes the damaged chain plate, replaces the new chain plate, and installs the chain plate pin and the pin positioning buckle. The above replacement process requires the cooperation of at least two workers to complete the operation. The entire replacement process greatly increases the labor intensity of the workers, and the maintenance time is long, time-consuming and labor-intensive, which seriously affects the effective operation of the chain conveyor.
