Technical Field

The invention relates to the technical field of post-welding treatment, in particular to a stable heat preservation device for a welding trolley.

Background

The foundation ring is an important part for connecting the fan cylinder with the foundation. In the existing fan, the wall thickness of the flange of a plurality of foundation rings is smaller than that of the cylinder body of the foundation ring, so that the wall thickness becomes a weak link of the foundation ring. In order to improve the whole bearing capacity of the foundation ring, one method is to cut off the weak area of the old flange and then weld a new reinforced flange. The cutting and welding of the foundation ring can be accomplished by a welding carriage.

The problem of cracking caused by residual welding stress and deformation due to rapid cooling after the welding of the cylinder is solved, especially in winter; at present, the method for eliminating stress is to perform manual stress elimination treatment after welding, which wastes time and labor.
