Description

Technical Field

[0001] The utility model relates to the technical field of weld processing equipment, in particular to a multi-position weld excess height processing equipment. Background Art

[0002] During the joint welding process, the weld excess is equivalent to the role of heat preservation and tempering for the outermost strength weld. After this role is completed, the weld excess will cause stress concentration, which is not conducive to the load-bearing of the welded structure, so the weld excess grinding operation must be carried out.

[0003] During the erection of the steel tower at the bridge site, the grinding environment for the weld residual height between the steel tower segments is relatively harsh. The traditional method is for the operator to stand on the construction platform on the outer facade of the steel tower with an angle grinder in hand to perform the grinding operation. Although the grinding method is simple, the grinding time is long, the labor intensity of the operator is high, and there are certain safety risks during the high-altitude operation. In addition, during the grinding process, the welds are often unevenly ground, the transition between the weld edge and the parent material is not smooth, and even the parent material is damaged; another method is to hang a hanging basket on the cross-section of the steel tower and install the grinding equipment on the hanging basket. Although this method reduces the labor intensity of the operator, this type of hanging basket cannot move horizontally, and cannot complete the grinding of the horizontal full-length welds at one time. In addition, the amount of work required to erect and dismantle the hanging basket will affect the construction period of the steel tower and increase the construction cost. Utility Model Content
