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 surface; the lower part of one end of the swing arm is fixedly connected with an elastic member; the other end of the swing arm is hinged with a fixing pile; and the elastic member and the fixing pile are fixedly connected with the ground. The invention provides the loop trolley fixing device, so that loop trolleys are fixedly arranged in a loop according to production requirements, smooth unhooking can be realized between trolleys and non-uniform space between the loop trolleys is prevented. A steel band is prevented from contacting the ground, and the surface of the steel band is prevented from being scratched so as not to affect the quality of the steel band, so that normal operation of the steel band 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.
