Description
Technical Field
The invention relates to the technical field of maintenance tools, in particular to a maintenance tool for tightening a chain and a chain maintenance method.
Background
In an industrial production workshop, in order to conveniently transport or transfer raw materials or processed products, a track for guiding the transport trolley to move and a chain which is parallel to the track and used for driving the trolley to move are arranged on the ground.
Because the general quality of the goods that need load in the dolly is great, consequently in the long-term use, the pulling force that receives on the chain is great to lead to the link joint of chain to break off easily, under the effect of the direction that exists at chain both ends mutually the back of the body, the both ends of chain fracture position can be quick keep away from distance far away from each other. In order to repair the chain, both ends of the broken portion of the chain are first coupled and butted again, and then the broken link plate is replaced to reconnect the chain.
Although an operator may manually pull one end of the broken portion of the chain to butt the two ends of the broken portion of the chain away from each other, the chain is usually very long, and thus the weight of the chain made of a metal material is very heavy, which makes it difficult to manually pull the chain. Therefore, the two ends of the broken part of the chain are butted by a winch or an electric block, specifically, a hook is hooked on one end of the broken part of the chain, then the hook is connected to the winch or the electric block, the winch or the electric block is started to pull the broken end of the chain, and the two ends of the broken part of the chain are butted.
However, technicians find that when the chain breakage end is pulled by the winch or the electric block, the chain can be separated from the ground, it is difficult to judge whether the chain breakage end has moved in place, and the situation that the chain breakage end has been pulled often occurs, so that manual adjustment needs to be performed on the butt joint situation of the chain breakage end, and operation difficulty is caused.
And when the butt joint of the two ends of the chain fracture part is completed by using the winch or the electric hoist, the continuously reeled twisted rope or the continuously reeled pulling rope can continuously swing, so that the pulling force direction for pulling the chain fracture end is also continuously swung, and the two ends of the chain fracture part are easy to dislocate when in butt joint.
