Safety protection device of rolling mill press head

Abstract

The invention discloses a safety protection device of a rolling mill press head. The invention is achieved through the technical scheme that a press lead screw of a platform on the top of a rolling mill is connected with a press head, wherein two sides of the press head are respectively welded with a hanging ring, and the hanging rings are respectively connected together with the platform on the top of the rolling mill respectively through a U-shaped lock and a steel wire rope. According to the invention, grave personal injury accidents caused by the fall-off of the press head after a press head fixing bolt is broken off is avoided so that safe production is realized.

Description

technical field [0001] The invention relates to the field of steel manufacturing and processing equipment, and more specifically relates to a safety protection device for a pressure head of a rolling mill. Background technique [0002] In the process of changing rolls and overhauling, operators and mechanical fitters must often enter the inside of the rolling mill to check the cooling water nozzle, or complete maintenance items such as replacing the liner and checking the universal shaft liner. Since the pressure head is 1 meter away from the human head Left and right, and the weight of the indenter is 200kg. The diameter of the bolts used to fix the indenter is M12, and some bolts are often broken during the production process, which is not easy to check and maintain. If the indenter falls off, it will cause serious personal injury. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rolling mill ram safety protec...
