Technical Field

The utility model relates to a roll changing hook head device of a rolling mill working roll, belonging to the technical field of steel rolling equipment in the metallurgical industry.

Background

In the prior art of steel rolling, when a working roll is replaced, the working roll is pulled out or pushed into a rack through a hydraulic cylinder, a hook head is a device for connecting the hydraulic cylinder and a working roll bracket, when the device is used, a cylinder rod of the hydraulic cylinder is connected with the hook head, the hook head is hung on the working roll bracket, and the roll is pushed in or pulled out under the action of the hydraulic cylinder. The method has the disadvantages that along with the continuous increase of the roll changing times, a plurality of disadvantages of the original roll changing hook head are exposed, the roll changing hook head can not be lifted and descended frequently, if the hook head can not be lifted or descended, the hook head needs to be lifted or descended manually, time and labor are wasted, the roll changing time is increased, and the steel rolling rhythm is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a roll changing hook head device for a rolling mill working roll, which is convenient for changing the working roll, reduces the roll changing time, reduces the labor intensity of operators and solves the problems in the background technology.

The technical scheme of the utility model is as follows:

the utility model provides a rolling mill working roll change gib head device, contains gib head, lever, spring plate, wheel, frame, pulley, pivot, round pin axle A, round pin axle B and round pin axle C, and the below of frame is equipped with the wheel, and the gib head rotates through round pin axle A to be connected on the frame, and the one end of lever rotates through round pin axle B to be connected on the gib head, and the centre of lever rotates through round pin axle C to be connected on the frame, is equipped with the spring plate directly over the gib head, the one end of spring plate is connected in the pivot, and the pivot is fixed on the gib head, and the other end of spring plate is equipped with the pulley.

The one end of gib head is equipped with the hook with work roll bracket matched with, and the centre of gib head rotates through round pin axle A and connects on the frame, and the one end that the gib head was equipped with the hook is fixed in the pivot.

And a fulcrum matched with the pulley is arranged on the frame.

The lever is bent, and the bent part of the lever is rotatably connected to the frame through a pin shaft C.

When the roller changing platform is touched by a lever, the hook head rotates around the pin shaft A, so that one end with the hook is lifted up, the hook head is lifted up along with the hook head through the spring plate, and after the hook head is lifted up to the position, an operator can recover the roller changing cylinder, and the hook head is lowered to the horizontal position immediately, so that the whole roller changing work is completed.

The utility model has the beneficial effects that: the replacement of the working roll is convenient, the roll replacement time is reduced, and the labor intensity of operators is reduced.
