And chamfers are arranged at the connecting parts of the first pin shaft, the second pin shaft, the third pin shaft and the balance body.

Compared with the prior art, the beneficial effects of the utility model are that:

1) the utility model comprises a balance body, a fork, a first pin shaft, a second pin shaft and a third pin shaft; the two forks are fixedly connected in front of the balance body in parallel, the first pin shaft and the second pin shaft are connected with a main lifting hook of the hundred-ton crane through a steel wire rope, and the third pin shaft is connected with an auxiliary lifting hook of the hundred-ton crane through the steel wire rope.

The utility model discloses utilize fork truck's theory of operation, use the balanced mode of lever, at first insert the broken roll below with the fork through hundred tons of cranes, then lift by crane the operation, lift up the high back and slowly take out the rolling mill, take out the broken roll. And the main and auxiliary lifting hooks of the hundred-ton crane are simultaneously lifted for operation, so that the roller breakage during finish rolling can be rapidly processed.

2) The balance body is formed by simply processing a hot rolling raw material plate blank, and the cost is low.

3) And chamfers are arranged at the connecting parts of the first pin shaft, the second pin shaft, the third pin shaft and the balance body, so that damage to the steel wire rope during operation is prevented.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

as shown in fig. 1, 2 and 3, a device for rapidly processing roll breakage of a finishing mill comprises a balance body 1, a fork 2, a first pin shaft 3, a second pin shaft 4 and a third pin shaft 5.

The balance body 1 is a cuboid, the balance body 1 is made of a hot-rolled raw material plate blank, and the balance body 1 is required to be 65Mn high-strength spring steel, and has the length of 5000mm, the width of 1400mm and the thickness of 280 mm.

The fork 2 is L-shaped, the bending part is a round angle, the thickness of the fork 2 is more than 80mm, the length is 5000mm, and the width is 150 mm. The two forks 2 are fixedly connected in parallel with each other in front of the balance body 1, and the distance between the outer edges of the two forks 2 is 650 mm. The distance between the pallet forks 2 corresponds to the diameter of the working roll. The head of the fork 2 is thinned, so that the insertion is facilitated.

The first pin shaft 3, the second pin shaft 4 and the third pin shaft 5 are identical in structure and are composed of a round rod 9 and a baffle disc 10, the diameter of the round rod 9 is 100mm, and the diameter of the baffle disc 10 is 200 mm.
