Hydraulic roll changing device for rolling mill work roller

Abstract

The invention discloses a hydraulic roll changing device for a rolling mill work roller. The hydraulic roll changing device for the rolling mill work roller comprises a fixing shelf arranged at the front end of the rolling mill work roller, the outer side wall of the fixing shelf is jointed with a hydraulic support rod, which is arranged obliquely and upwards, the end of the hydraulic support rod is connected with a hydraulic oil cylinder flatly arranged, the hydraulic oil cylinder is connected with the a pull rod provided with a drag hook and hanged to the rolling mill work roller corresponding to the end of the rolling mill work roller; the hydraulic oil cylinder is horizontally located above the fixing shelf and the lower part of the middle thereof is jointed to the end of the hydraulic support rod through a connection end; the hydraulic roll changing device for the rolling mill work roller is simple in structure, convenient and reliable in use, can raise the roll changing efficiency and reduce the use cost.

Description

technical field [0001] The invention relates to a hydraulic roll changing device for working rolls of a rolling mill, and belongs to the technical field of matching roll changing mechanisms for working rolls of a rolling mill. Background technique [0002] In the prior art, the production of strip steel is mainly formed by rolling in a rolling mill. The rolling mill is equipped with work rolls for rolling the strip. Since the work rolls often need to be changed, once the roll needs to be changed It is required that the work roll system can be easily pulled out or sent in from the rolling mill to realize roll change; at present, this kind of roll change is carried out by a forklift; due to the large size of the forklift itself, it is inconvenient to enter and exit the rolling mill, and the efficiency is low , so be badly in need of a kind of roll changing device that can conveniently enter and exit the rolling mill. Contents of the invention [0003] The purpose of the pre...

[0002] In the prior art, the production of strip steel is mainly formed by rolling in a rolling mill. The rolling mill is equipped with work rolls for rolling the strip. Since the work rolls often need to be changed, once the roll needs to be changed It is required that the work roll system can be easily pulled out or sent in from the rolling mill to realize roll change; at present, this kind of roll change is carried out by a forklift; due to the large size of the forklift itself, it is inconvenient to enter and exit the rolling mill, and the efficiency is low , so there is an urgent need for a roll changing device that can easily enter and exit the rolling mill
