If the belt tightness of the bucket hoist is not appropriate, it will cause the belt of the bucket hoist to run deflected. There are some connecting screws on the base wheel bearing of the bucket hoist, and the length of these connecting screws can determine the distance between the bucket lifting head wheel and the bottom wheel, thus adjusting the tightness of the bucket hoist belt. And some components of the bucket hoist will be the hoist to produce a certain direction of tilt force, such as the placement of the drum and reprint point of the unloading position, will affect the hoist belt tightness. When all these components are debugged, the tension on both sides of the belt can be balanced.
In this paper, by analyzing the characteristics of the bucket hoist and the working situation, the concrete application method of the automatic adjustment method of the belt tightness of the hoist is obtained. Bucket hoist in general will be used in the quantity and weight of the transport, it is very fast transport, in the process of lifting high stability, because of the high lifting height of the bucket hoist, the lifting process has the characteristics of complete cargo sealing, by the construction industry and the construction raw materials industry favored. Although it has been widely used by many large enterprises, but it still has shortcomings, in the daily use of the process, bucket hoist belt will often appear the phenomenon of tightness, this phenomenon will lead to the lifting machine in the raw materials are not thoroughly unloaded, there are some raw material residue occupied the hopper space, In the course of two transport, the material becomes less, the transportation efficiency decreases, when the belt runs seriously, there will be the side of the card and tear and so on, directly damaged the belt itself. Therefore, through research and experiments to solve the phenomenon of bucket hoist belt running deviation, through reasonable debugging to ensure the tightness of the belt.
