Abstract

The invention provides a large-span rack movable type rolling mill drag chain device which comprises a first sliding rail, a second sliding rail, a supporting frame and drag chains. The first slidingrail is installed on a transmission side fixed rack platform, the second sliding rail is installed on an operation side movable rack platform, the first sliding rail and the second sliding rail are oppositely arranged, and the two ends of the supporting frame are connected with the drag chains. the ends, away from the supporting frame, of the drag chains are arranged at the bottom of the supporting frame, the ends, away from the supporting frame, of the two drag chains extend inwards, the end, away from the supporting frame, of one drag chain is fixedly connected with the transmission side fixed rack platform, and the end, away from the supporting frame, of the other drag chain is fixedly connected with the operation side movable rack platform; and rollers are installed at the two ends ofthe supporting frame through installation frames. According to the large-span rack movable type rolling mill drag chain device, the problem that when the drag chains work, the supporting force cannotsupport the sum of the self weight of the drag chains and the weight of a plurality of connecting pipelines, so that the work of the movable type rolling mill is influenced, and the movable type rolling mill cannot work is solved.

Description

technical field [0001] The invention belongs to the technical field of large-span movable rolling mills, and in particular relates to a drag chain device for large-span movable rolling mills. Background technique [0002] When the large steel frame movable rolling mill needs to open the frame for changing the roll system, etc., the distance to open the movable frame on the operation side is long, and the pipelines required for equipment work need to pass through the drag chain and the pipes of the fixed frame on the transmission side. road connection. When the drag chain is working, the supporting force cannot support the sum of the weight of the drag chain and the weight of many connecting pipelines, so that the work of the movable rolling mill is affected and it becomes an urgent problem to be solved. Contents of the invention [0003] In view of this, the present invention proposes a movable rolling mill drag chain device with a large span frame to solve the problem th...
