Pipeline anti-corrosion rotary clamping device

Abstract

The invention discloses a pipeline anti-corrosion rotary clamping device. The pipeline anti-corrosion rotary clamping device solves the problems in the prior art that pipe coaxial clamping cannot be achieved and movement is inconvenient. The pipeline anti-corrosion rotary clamping device is characterized in that universal wheels are arranged at the four corners of a base so that movement can be facilitated; a support base is arranged on the base through a support frame, a rotary sleeve is rotatably supported in an inner cavity of the support base, and a motor drives the rotary sleeve to rotatethrough a transmission gear; and an electric push rod is coaxially fixed in an inner cavity of the rotary sleeve, clamping arms are symmetrically hinged to a fixed sleeve of the electric push rod, clamping blocks are symmetrically arranged on the clamping ends of the clamping arms, and support rods are hinged between the middle portions of the inner sides of the clamping arms and a telescopic rodof the electric push rod; and a centering fixed rod coaxially fixed together with the telescopic rod is coaxially connected with a centering shaft through a connecting sleeve. The centering shaft cooperates with the clamping arms and the clamping blocks to conduct centering clamping, the pipeline is stable, and the pipeline anti-corrosion rotary clamping device is suitable for clamping when the pipeline is subjected to anti-corrosion treatment.

Description

technical field [0001] The invention relates to a workpiece clamping device, in particular to a pipe anti-corrosion rotary clamping device. Background technique [0002] In order to prevent pipelines from being corroded by soil, air and transport media, such as oil and natural gas, it is necessary to carry out anti-corrosion treatment on the outer and inner walls of metal pipelines. At present, the anti-corrosion treatment of pipelines is usually to place two parallel channel steels on the ground, then place the pipelines on the channel steels, first derust and anti-corrosion the upper surface of the pipelines, after the treatment is completed, manually rotate the pipelines, and put the lower surface of the pipelines Rotate to the top, and then carry out rust removal and anticorrosion treatment. This kind of manual rotation pipeline is prone to leaking treatment parts, and the efficiency of rust removal and anticorrosion treatment is low. For this reason, many technicians a...
