Abstract

The utility model relates to the technical field of cold-rolling mills, in particular to an automatic hook collision device. The automatic hook collision device comprises a supporting roller, a roller replacement hook, a cover plate, a weight, a cocking rod and a roller replacement cylinder. The supporting roller is connected with the roller replacement hook through a hook. The weight is arranged on the roller replacement hook. The cocking rod is arranged above the roller replacement cylinder. The cocking rod is arranged inside the cover plate. The automatic hook collision device is simple in structure and convenient to operate, so that roller replacement time is shortened, the roller replacement process is smooth; meanwhile, a worker does not need to go into a melt pit for operation, so that the automatic hook collision device is safe and convenient to use.

Description

Automatic hooking device

Technical field

The utility model relates to a kind of cold-rolling mill and changes hook device, relates in particular to a kind of automatic hooking device.

Background technology

In the prior art, back roll of cold-rolling machine changing rig is positioned at the fore side of milling train, be used for changing lower support roll on milling train, impact when conventional changing rig utilizes roll change cylinder to stretch out makes the hook perk on back-up chock, falling rear roll change hook and bearing block hook hooks automatically, roll change hook is retracted, pull out old roller, utilize overhead traveling crane to hang away old roller, change new roller, and then push away new roller and return frame, finally need in trench, to lift the hook on bearing block under workman, disconnect hook, roll change cylinder is retracted, and roll change finishes.The inconvenient workman's operation of this decoupling device mode, has increased work dangerous, also relatively loses time.

Summary of the invention

The technical problems to be solved in the utility model is: the inconvenient workman's operation of the existing mode of purchasing on a barter basis, increased work dangerous, and also relatively lose time, a kind of automatic hooking device is provided.

In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical problem adopts: this automatic hooking device comprises backing roll, roll change hook, cover plate, pouring weight, sticks up bar and roll change cylinder, backing roll connects roll change hook by hook, roll change hook is provided with pouring weight, the top of roll change cylinder is provided with sticks up bar, sticks up bar and is placed in cover plate.

The beneficial effects of the utility model are: this automatic hooking device simple in structure, easy to operate, shortened roll changing time, and roll change process is more smooth, does not need workman descend melt pit to operate simultaneously, safe ready again.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

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

Wherein: 1, backing roll, 2, roll change hook, 3, cover plate, 4, pouring weight, 5, stick up bar, 6, roll change cylinder.

The specific embodiment

Fig. 1 is structural representation of the present utility model, figure comprises backing roll 1, roll change hook 2, cover plate 3, pouring weight 4, sticks up bar 5 and roll change cylinder 6, and described backing roll 1 connects roll change hook 2 by hook, and roll change hook 2 is provided with pouring weight 4, the top of roll change cylinder 6 is provided with sticks up bar 5, sticks up bar 5 and is placed in cover plate 3.

While utilizing roll change cylinder 6 to stretch out in practical operation, roll change hook 2 clashes into the hook on backing roll 1, and impact makes pouring weight 4 perks on roll change hook, and hydraulic cylinder moves on, and pouring weight 4 falls after rise and can link up with, and hits like this hook process very stable; Pull out after old roller, utilize overhead traveling crane to hang away old roller, change new roller, then push back in rolling-mill housing.During decoupling device, workman may stand on removable cover 3, open the lid of decoupling device top on cover plate, to stick up bar and insert this device, utilize lever principle to move and stick up bar 5, only need very little power just the perk of roll change hook saddle weight end to be pinned and stuck up bar with safety pin simultaneously, make it to remain on perk state, roll change cylinder is retracted, and roll change process finishes.

This automatic hooking device simple in structure, easy to operate, has shortened roll changing time, and roll change process is more smooth, does not need workman descend melt pit to operate simultaneously, safe ready again.
