Pipeline angle conversion device for chemical equipment module production

Abstract

The invention discloses a pipeline angle conversion device for chemical equipment module production, which comprises a rack, a lifting seat driven by a lifting power device is slidably mounted on the rack along the Z axis, a rotating seat driven by a rotating power device is rotatably mounted on the lifting seat around the X axis, a telescopic arm which stretches out and draws back along the X axis direction is mounted on the rotating seat, the telescopic arm is driven by a telescopic power device, the free end of the telescopic arm is provided with two clamping jaws which are driven by a clamping power device to clamp a pipeline, the clamping jaws are provided with rotation driving devices which drive the pipeline to rotate around the clamping center lines of the clamping jaws, and the angle conversion device can well adjust the angle of the pipeline. Therefore, the welding seam can be conveniently adjusted to be in a flat welding position or a horizontal welding position.

Description

technical field [0001] The invention relates to a pipeline angle conversion device, in particular to a pipeline angle conversion device for chemical equipment module production. Background technique [0002] The main process of modular production of chemical equipment is to pre-weld pipe sections of various shapes and orientations in the workshop, and then assemble and weld several pipe sections with pipe sections and equipment or containers to form several chemical sub-modules with certain technological characteristics. The modules are transported to the production site for assembly and butt welding to form a complete chemical plant production line. Since the main welding operations of this process are completed in the workshop, the welding quality can be well guaranteed. For process pipelines, it is generally necessary to prefabricate and weld straight pipes and fittings to form pipe sections, which facilitates the assembly and welding of subsequent sub-module process pip...

AI Technical Summary

Problems solved by technology

At present, the prefabricated welding of pipe sections mainly adopts manual welding by welders. Since the specifications and sizes of straight pipes are different, different clamping devices are required for clamping during welding. Due to manual welding by welders, the spatial position of the weld seam cannot be too high. Based on the above Some welds cannot be well adjusted to the flat welding or horizontal welding position 2G, so that the welder can only choose other welding positions, such as 5G, 6G vertical full-position welding, which increases the welding cost of the weld Difficulty, high requirements on welding skills of welders, high risk of welding quality

In addition, manual welding by welders is labor-intensive
