Description

A hoisting device for replacing the sinking roller in the cleaning section

technical field

The utility model relates to a hoisting device for replacing a sinking roller in a cleaning section, which belongs to the technical field of cold rolling equipment.

Background technique

The cleaning section is an important process component of the cold rolling continuous annealing line and continuous galvanizing line of metallurgical enterprises. The cleaning section is generally designed as a two-story concrete platform. On the second floor, the scrubbing box, the rinsing box and the horizontal box body part for hot alkali cleaning and electrolytic cleaning are placed. There are sunken rollers at the bottom of the vertical box of the hot alkali washing box and the electrolytic cleaning box. Due to the blockage of the concrete platform, the plant crane cannot be used when replacing the sunken rollers, and the maintenance operation is relatively difficult. Some production lines are equipped with roller changing carts. When the roller changing cart system is used to change the rollers, push the roller changing cart to the operation side, hang the end of the roller shaft with a hanging chain, and support the drive side roller shaft by the support arm on the drive side. The side drive side operates at the same time, and the rollers are drawn out from the operation side. Since the roller changing cart has no drive and no track, it is very laborious to push, and it is difficult to fix the position on the operation side, and the alignment control is not easy, and the time required for roller changing is very long. In view of this, it is necessary to design a roll changing device which is convenient to replace the sink roll, so as to solve the above problems.

Utility model content

The technical problem to be solved by the utility model is to provide a hoisting device that can easily and quickly replace the sinking roller of the cleaning section, thereby reducing the labor intensity of maintenance workers and shortening the operation time of changing rollers.

The technical scheme of the present utility model is:

A sunken roller replacement hoisting device in a cleaning section includes a beam, a monorail trolley, a chain hoist, and a counterweight. The counterweight is formed by welding a thick-walled steel pipe through a main counterweight, and the thick-walled steel pipe and the main counterweight are welded together. The upper reinforcing rib plate and the lower reinforcing rib plate are respectively welded, the upper reinforcing rib plate is provided with a lifting hole, the main counterweight is provided with a lifting lug, the monorail trolley and the chain hoist are assembled on the beam, the monorail trolley And the chain hoist is hung on the lifting ear and the lifting hole through the hook to lift the counterweight.

The main counterweight body is provided with an adjustment counterweight block, and the adjustment counterweight block is symmetrically fixed on both ends of the upper part of the main counterweight body through a stud, a nut and a washer.

The centerline of the thick-walled steel pipe is 120-200 mm above the horizontal position of the center of gravity of the main counterweight.

The inner diameter of the thick-walled steel pipe is 100-120 mm, and the wall thickness is 50-60 mm.

The weight of the main counterweight is 4500-6500 kg.

There are 1-4 hanging holes on the upper reinforcing rib plate.

The beneficial effects of the utility model are as follows: the utility model has the advantages of simple structure and convenient operation. After the above technical scheme is adopted, the roll changing operation is reduced from the original 8 to 4, and the operation time is reduced from 14 hours to 10 hours. It not only reduces the labor intensity of workers, but also shortens the operation time, improves labor efficiency, and creates greater economic benefits for the production plant.
