A method of welding modular steel frames using a rotating device

Abstract

The invention provides a method for conducting assembly welding of a modular steel frame through rotary devices. The method for conducting assembly welding of the modular steel frame through the rotary devices comprises the following steps that (1) the two rotary devices are arranged at the two corresponding ends in the length direction of the modular steel frame separately, wherein each rotary device is composed of a lateral supporting frame part, an electric wheel frame part and a fixed connecting support part; (2) the modular steel frame is hoisted and connected to the rotary devices, and the rotary devices are fixedly connected with modular corner pieces at the two ends of the modular steel frame; (3) after connection of the modular steel frame, a driving wheel is driven by a motor and transmission piece to rotate together with a round wheel track and the modular steel frame, and assembly welding is conducted after components needing to be assembly-welded to different positions of the modular steel frame are rotated to a worker operating position; and (4) after all the components are assembly-welded, the modular steel frame obtained after assembly welding is separated from the rotary devices, and thus assembly welding of the modular steel frame is completed. According to the method for conducting assembly welding of the modular steel frame through the rotary devices, the operating process is simple, the assembly welding efficiency is high, various operation risks are lowered, and the assembly welding quality is ensured.

Description

Technical field: [0001] The invention belongs to the technical field of steel structure modular buildings, and relates to a method for assembling and welding modular steel frames by using a rotating device. Background technique: [0002] The steel structure modular building is a highly integrated prefabricated building, usually consisting of a steel structure frame and a matching three-plate system plus decoration. Among them, the steel structure frame is generally a box-type space structure formed by welding square steel, H-shaped steel and other components. It is usually assembled and welded by manual arc welding on the factory assembly line. However, due to the characteristics of its space structure, assembly welding often requires such figure 1 The shown auxiliary scaffolding, horse stool or assembly welding platform, etc., together with component turning, can complete the welding of different parts of the weld (high position uses scaffolding and platforms and other devi...
