Pneumatic tailstock clamping system for pipeline welding

Abstract

The invention relates to a pneumatic tailstock clamping system for pipeline welding. The pneumatic tailstock clamping system comprises a containing plate, supporting plates are vertically fixed to the periphery of the bottom face of the containing plate, contact plates are fixedly connected to the bottom faces of the four supporting plates, and fixing frames are vertically fixed to the left side and the right side of the top face of the containing plate; and a bottom bin is fixedly connected to the position, located among the four supporting plates, of the bottom face of the containing plate, sliding rails are fixedly connected to the inner walls of the front faces and the inner walls of the back faces of the two fixing frames correspondingly, the four sliding rails are slidably connected with sliding blocks correspondingly, and the side faces, away from the sliding rails, of the four sliding blocks are fixedly connected with connecting blocks correspondingly. According to the pneumatic tailstock clamping system for pipeline welding, through clearance fit between clamping blocks and through holes, the clamping blocks can move conveniently and clamp pipelines of different specifications, meanwhile, under the action of annular springs, the clamping blocks are prevented from being separated from through grooves, air inlet pipes convey gas with pressure into a fixing bin, and the clamping blocks can clamp the pipeline more stably.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a pneumatic tailstock clamping system for pipeline welding. Background technique [0002] A pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump and boiler, the high pressure from the pipeline It can also be transported by the pressure or gravity of the fluid itself. The pipeline is widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil, natural gas, agricultural irrigation, hydraulic engineering and various in industrial installations. [0003] According to a pipeline clamping device disclosed in Chinese patent CN108027089B, the device can effectively prevent crevice corrosion of pipelines. Under the environment, after the oxide film is damaged, the anti-crevice corrosion components a...
