Roller support device or long-distance heavy-load drag chain idle

Abstract

A roller supporter for long-distance heavy-load drag chain features that the one end of the said drag chain is fixed to the foundation in the center of the roller supporting system and after passing through several roller, the another end of the said drag chain is fixed to its connection frame. The robot, speed-reducing drive motor and the connection frame are fixed to the baseplate of a moving carriage. Its advantages are no overbending of drag chain, long service life of drag chain, low resistance of carriage, and simple structure.

Description

technical field [0001] The invention relates to a rolling support device, in particular to a roller support device for a long-distance heavy-duty drag chain used in a mobile robot plasma cutting and scribing equipment for marine section steel, and belongs to the field of machinery. Background technique [0002] At present, for heavy-duty towlines with long strokes, in order to reduce the frictional resistance during the movement of the towline and prolong the service life of the towline, an effective way is to overcome the excessive bending of the towline during the movement and the upper section of the towline. Sliding friction between the lower segments. The current method to reduce this sliding friction is: arrange some anti-friction and wear-resistant linings or automatic sliding sleeves evenly at a certain interval on the bottom of the upper section or the top of the lower section of the drag chain (see German igus (igus) drag chain product sample), but this method is ...

AI Technical Summary

Problems solved by technology

This patent uses a plurality of cable splints to clamp the cables and hang them under the roller box. The cables between the cable splints will bend due to gravity. In addition, when dragging, the rollers roll on the steel wire rope. There will be fluctuations in the center, which will have an adverse effect on the trolley with movement accuracy requirements
