Description

Thin plate heat treatment suspender

The utility model belongs to the suspender technical field, particularly relates to a kind of sheet metal hot-cured suspender that is used for.

In background technology, iron and steel enterprise is when producing general steel plate and silicon steel plate, last production technology is heat treatment, during steel plate turnover annealing furnace, adopts the mode of steel rope lifting usually, the hidden danger of this lifting mode is more when using the steel rope lifting, to hang out annealing furnace with the bulging plate of placing steel plate, because of the bulging plate is to be cast by cast iron materials, period of service length will cause aging, cracking, therefore, adopt the mode of steel rope lifting not guarantee safe production; In heat treatment process, general steel plate or silicon steel plate are to need to hang out stove with the bulging plate to cool off outward, because of 2.5 tons of bulging plate deadweights, hang in table charging annealing after the cooling again, and black furnace platform and bulging plate heat power consumption 85kwh at every turn, and its electric power consumption is also very big.How eliminating safe hidden trouble and reduce consumption, is the problem that steel production enterprise faces.

The purpose of this utility model is to provide the thin plate heat treatment suspender that a kind of safety is good, simple in structure, easy to use, can cut down the consumption of energy significantly.

The purpose of this utility model is achieved in that it comprises big boatswain chair and suspension hook, it is characterized in that on the described big boatswain chair main shaft being housed, lifting shaft and floating axle, have companion way on the big boatswain chair, lifting shaft is positioned at companion way, and can upper and lower displacement in companion way, the two ends of lifting shaft flexibly connect with corresponding pitman respectively, the lower end of pitman cooperates with the suspension hook top movable, match with the inner on suspension hook top in the two ends of floating axle, main shaft is provided with little hook, on the little hook pulley is housed, disengaging bar is housed on lifting shaft, disengaging bar is provided with smooth convex surface, and the pulley on this convex surface and the little hook fits, and also is provided with the disengaging bar on suspension hook.

The utility model is compared with background technology, has reasonable in design, safe in utilization, easy and simple to handle, the sturdy and durable and characteristics that cut down the consumption of energy, is the desirable suspender that uses in iron and steel enterprise's thin plate Technology for Heating Processing.

In conjunction with the accompanying drawings and embodiments, the utility model is further described as follows:

Fig. 1 is the structural representation of facing of the present utility model
