Pipe film coating machine and method of use thereof

Abstract

The invention discloses a pipe film coating machine and a method of use thereof. The pipe film coating machine comprises a pipe clamping mechanism, a film coil winding mechanism and a pushing mechanism, wherein the pipe clamping mechanism is of a half-divided structure; the film coil winding mechanism is arranged at the inner side of the pipe clamping mechanism, and a moving mechanism is arrangedat the outer side of one end of the pipe clamping mechanism; the pipe clamping mechanism comprises first support plates and second support plates, the two first support plates are respectively distributed on one side in the axial direction, and the two second support plates are respectively distributed on the other side in the axial direction; the support plates on the same side are connected by afirst positioning bolt extending axially, and the first support plates and the second support plates that are assembled with each other are fixed and assembled by mounting plates; and the pipe clamping mechanism also comprises a pipe pressing mechanism on the outer sides of the complete support plates, the pipe pressing mechanism comprises at least two pressing wheels distributed along the circumference of the complete support plates, and the pressing wheels can extend and contract in the radial direction of the support plates to realize the compaction on a pipe. The pipe film coating machinehas the advantages of not requiring manual direct operation, and having high efficiency and low cost.

Description

technical field [0001] The present application relates to the technical field of secondary wrapping of the protective layer outside the pipeline, in particular to a pipeline coating machine and its usage method. Background technique [0002] The external protective layer of oil and natural gas pipelines that have been used for a long time will naturally age. Once the protective layer ages, it needs to be replaced with a new protective layer. Wrap the protective film on the outer wall of the Daao pipeline. This artificial coating will inevitably lead to low efficiency, harsh working environment (big sandstorm, high temperature), and high operating costs. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the technical solution adopted in this application is: a pipeline coating machine that does not require manual direct operation, has high efficiency and low cost. [0004] In order to solve the above technical problems, the technic...

Problems solved by technology

[0002] The external protective layer of oil and natural gas pipelines that have been used for a long time will naturally age. Once the protective layer ages, it needs to be replaced with a new protective layer. Wrap the protective film on the outer wall of the Da'ao pipeline. This artificial coating will inevitably lead to low efficiency, harsh working environment (big sandstorm, high temperature), and high operating costs.
