Abstract

The invention discloses a clamping positioning mechanism for a V-shaped wheel of an airtight automatic de-rusting machine for a pipeline repaired port. The clamping positioning mechanism is designed for the positioning and driving of a horizontal walking device of an automatic de-rusting machine. A V-shaped wheel set is fixed under a base plate by utilizing the parts, such as a clamping wheel shaft, and the like, the V-shaped wheel set is in clamping contact with a guiding polish rod, and the accurate positioning and the excellent driving of the horizontal walking device on a four-driving walking device are realized, so that the smooth performing of a horizontal de-rusting process of the automatic de-rusting machine is ensured. The clamping positioning mechanism has a simple structure, is convenient to operate and has strong adaptive capacity to an outdoor construction environment.

Description

technical field [0001] The invention relates to a V-shaped wheel clamping and positioning mechanism for a closed automatic rust remover for pipeline joints, and belongs to the technical field of oil and gas pipeline construction. Background technique [0002] With the continuous and rapid development of my country's energy industry, long-distance oil and gas pipelines have become an important way of energy security. In the construction of oil and gas pipelines, in order to ensure the service life of the pipeline, the anticorrosion of the joint section of the pipeline is particularly important, and the quality of the surface treatment of the pipeline in the anticorrosion process directly affects the service life of the anticorrosion layer. In the current pipeline construction, the surface treatment of the pipeline in the mending section is manual operation and open sandblasting, which brings serious environmental pollution, increased labor intensity of workers, damage to the ...
