Abstract

The invention relates to a roll changer of a support roll. The roll changer comprises a shaft, wherein one end of the shaft is connected with a roll through a connector while the other end of the shaft is provided with a balance block; two ends of the balance block are locked through first locking plates; a hanging member is arranged at a fulcrum part in the middle of the shaft; two ends of the hanging member are locked through second locking plates; and a handle is arranged at one side of the balance block and on the shaft through a fastener. According to the invention, through the balance principle, the balance block is arranged on the shaft to balance the two ends of the shaft; and through a method of running, hanging and moving at the fulcrum part, the roll change is realized conveniently; and the roll changer is simple in operation, low in cost and high in efficiency.

Description

technical field [0001] The invention relates to rolling mill auxiliary equipment in the metallurgical industry, in particular to a support roll changing device. Background technique [0002] In metallurgical production, when the rolling mill equipment is working, the roll system is generally composed of backup rolls, intermediate rolls, work rolls, etc., which is an important part of the rolling mill equipment. The rolls in the roll system are always subject to changes in direction and size. of the rolling force. The long-term use of the roll will cause fatigue wear or damage, and the roll needs to be maintained or replaced. In the prior art, manual and driving are used to cooperate with each other to push and pull. However, due to the high quality of the roll, it is usually difficult to achieve, and there are problems big security risk. Contents of the invention [0003] Aiming at the disadvantages of difficult roll changing and potential safety hazards in the above-men...
