Description

Automatic hoisting device of hood-type annealing furnace Technical Field The application relates to the technical field of lifting devices, in particular to an automatic lifting device of a hood-type annealing furnace. Background The cover annealing is to anneal the cold rolled sheet strips in the cover furnace in a stacking mode, so that in the using process, materials are generally placed on a base, then the outer cover, the inner cover and the like are lifted on the middle of the base through a lifting device, and the lifting device is used for assisting in lifting the materials. For example, patent document with publication number CN215249114U discloses a lifting device of annealing furnace bell, through set up respectively in the track of annealing furnace operation side and transmission side, sliding connection in orbital frame, set up in hoist and the hanging chain that is used for connecting the annealing furnace bell at frame top have brought the operation safety, and it is convenient to use, have avoided the broken area of production line or the furnace roller nodulation maintenance operation lifting bell to appear colliding with the phenomenon, security, stability and the high efficiency of assurance annealing furnace open cover maintenance in-process that can be fine have improved the operating factor of production line, have promoted the benefit of equipment running quality.
