Special welding frame for bottom of large boiler

Abstract

The invention relates to the technical field of large boiler manufacturing, in particular to a welding frame special for the bottom of a large boiler, which comprises a bottom frame and two frame bodies fixed on the bottom frame and symmetrically distributed, and further comprises a bearing mechanism arranged on the two frame bodies; the two transverse welding rails are symmetrically arranged in the transverse middle of the bottom frame and are not connected with each other; the longitudinal moving mechanism is arranged in the longitudinal middle of the bottom frame and located between the two transverse welding rails; the welding mechanism is arranged on the longitudinal moving mechanism, longitudinally moves along the longitudinal moving mechanism and is adaptively connected with the transverse welding track, so that the welding mechanism enters the transverse welding track for welding; and the positioning mechanism is arranged on the transverse welding track, located on the rear side of the welding mechanism and used for positioning when the welding mechanism is connected with the transverse welding track. The problems that in the prior art, a worker needs to conduct welding in a lying welding or head-down overhead welding posture, so that the welding difficulty is increased, and the body of the worker and the welding quality of a boiler are affected are solved.

Description

technical field [0001] The invention relates to the technical field of large boiler manufacturing, in particular to a special welding frame for the bottom of a large boiler. Background technique [0002] Boiler is a kind of energy conversion equipment, including electric boiler, coal-fired boiler, gas boiler, biomass boiler and so on. Large boilers are often used in industrial applications. Due to the large size of large boilers, in the process of manufacturing and welding, for the top area of ​​the boiler, welders usually use lifts or tools to weld the boiler. As for the bottom area of ​​the boiler, the traditional method is to hoist the boiler with lifting equipment, and then the workers perform welding in the position of lying down or bowing their heads, which not only increases the difficulty of welding, but also affects the body of the workers and the welding quality of the boiler. Therefore, the welding process for the bottom of large boilers has always been a headach...
