Background

At present, a continuous elevator is mostly used for logistics, storage, goods conveying and other occasions, the continuous elevator is widely applied in industrial production, and the abnormal problem of the elevator caused by the gear jumping problem often occurs in the using process of the continuous elevator. The existing continuous elevator tensioning shaft assembly has the following common problems:

1. the Z-shaped tray lifter adopts a frame type structure, vertical up-and-down conveying is realized, two vertical parallel annular lifting chains are arranged on a rack, a plurality of tray assemblies with corresponding positions are arranged on the lifting chains belonging to the two chains respectively, so that products can be lifted up and lifted up simultaneously, and the lifting chains belonging to the chains are wound on respective driving wheels, tensioning wheels and driven wheels. The driving motor drives the two lifting chains to move synchronously so as to carry out cyclic lifting. If use a period of time after, can observe through the observation window, see the phenomenon that lift both sides chain rocked: the amplitude of the swing of the elevator exists during operation; whether the driving shaft is abraded or not, whether the chain guide is inclined or not and the like can result in the staggered teeth of the lifting chains on two sides, so that the phenomenon of asynchronous fault of the lifting chains on two sides is caused.

2. Due to the fact that the chain runs for a long time, the driving wheel, the driven wheel, the tension wheel and the like are likely to be abraded to a certain degree, in addition, certain abrasion can also occur to a shaft pin connected to the chain of the elevator, the chain is enabled to be loosened to a certain degree, in the running process of the elevator, the chain can shake, when the swaying chain moves to the tension wheel and the driven wheel, the chain and the gear are not normally meshed, and the condition that the Gedeng is easily caused, so that the conditions that the chain is dislocated and dislocated are caused.

3. When the elevator is used, the tray bears 100 Kg/disc, 5 discs in total, and about 500Kg in total, the chains sag due to gravity, the two lifting chains are inconsistent in elasticity, and the phenomenon of asynchronous two chains caused by staggered teeth of the chains at one side occurs.

4. The long-term operation of the equipment has equipment failure, after abnormal treatment is completed, the lifting chains on two sides need to be synchronously adjusted, the tensioning shaft is loosened, the lifting chains on two sides are marked at the same position relatively, the motor is inching to operate and manually interfere to adjust the teeth, whether the lifting chains on two sides are synchronous or not is repeatedly determined, the tensioning shaft is tightened again and trial operation is carried out, if the lifting chains on two sides are asynchronous, the tensioning shaft is repeatedly tightened, the teeth are adjusted through manual interference, and the lifting chains on two sides are always adjusted to be synchronous. The adjustment process is complex and repeated, and the process period is long (the adjustment period is more than or equal to 2 hours, and the abnormal processing time is not included).

At present, no optimal scheme is available in industrial production, and the problem of gear tooth loss in the operation of a hoister can be effectively solved.
