The beneficial effects of the utility model are as follows: the steel platform is a separated structure, a double-layer steel mesh is installed in the middle, and the mesh holes of the steel mesh are staggered, so that the waste chips are double-buffered when flying out, and the guide plate tilted downward in the middle of the workbench guides the waste chips to fall into the material receiving trough below, avoiding environmental pollution and safety hazards caused by the splashing of waste chips, and the bracket allows the truss assembly to be suspended above the steel platform for welding, reducing the damage to the steel platform during the link process, and the axle roller set in the middle of the bracket can move the welded truss, which is convenient for the next step of work, improves the work efficiency, and makes the device work more stably. The device has the characteristics of simple operation, efficient work, stable structure and strong practicality.

[0004] However, when the welding support device for the steel platform is in use, although the steel platform can be conveniently slid and taken, the sliding roller is always in contact with the steel platform, which makes the synchronous positioning effect of the steel structure after placement and the telescopic use of the sliding roller not very convenient, resulting in the steel platform being offset when welding the steel structure, thereby reducing the welding quality of the steel platform.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a welding support device for a steel platform is proposed. Utility Model Content
