Loop trolley fixing device

Abstract

The invention discloses a loop trolley fixing device, which comprises a swing arm, wherein the swing arm is provided with a groove; one end of the swing arm is provided with an inclined plane; the lower part of one end of the swing arm is fixedly connected with an elastic piece; the other end of the swing arm is hinged with a fixed pile; and the elastic piece and the fixed pile are fixedly connected with the ground. Through the loop trolley fixing device, loop trolleys are fixed in a loop according to the production requirement, so that the trolleys can be smoothly unhooked, and non-uniform distance between the loop trolleys is prevented. A steel strip is prevented from being in contact with the ground to scratch the surface of the steel strip and affect the quality of the steel strip, and normal operation of the steel strip is realized.

Description

technical field [0001] The invention relates to a looper trolley fixing device, which is suitable for fixing the looper trolley of a rolling mill in a steel strip production line. Background technique [0002] At present, the positioning of the looper trolley at home and abroad is mainly to realize the fixation of the looper trolley through the boss card position. In this fixing method, the looper trolleys cannot be decoupled smoothly, and the looper trolley cannot be fixed in the looper according to the production requirements. . In actual production, when the processes of punching, reducing, building and withdrawing take place, the steel strip is easily affected by tension changes and vibrates up and down. After the looper trolley is stressed, it moves back and forth in the looper. As a result, the trolleys that should be arranged equidistantly in the looper cannot be arranged equidistantly, and the distance between the looper trolleys is different. Especially in places ...

AI Technical Summary

Problems solved by technology

After the looper trolley is stressed, it moves back and forth in the looper. As a result, the trolleys that should be arranged equidistantly in the looper cannot be arranged equidistantly, and the distance between the looper trolleys is different.

Especially in places with large spacing, the steel belt is affected by gravity and sags and contacts the ground, which causes friction between the steel belt and the ground during operation, causing scratches on the steel belt surface and affecting the quality of the steel belt.
