Description

Technical Field

[0002] A natural gas pipeline is a pipeline that transports natural gas from the extraction site or processing plant to the city gas distribution center or industrial enterprise users. However, the pipeline is not a whole pipe and needs to be connected during the laying process. During the installation, a pipe jacking construction device is required.

[0003] The prior art discloses a novel gas pipeline jacking construction device (publication number: CN115654215A), comprising: a mobile base; a shear frame is rotatably installed on the upper end of the mobile base through a rotating shaft; a support platform is fixedly installed on the upper end of the shear frame; a lifting adjustment frame is fixedly installed on the right side of the bottom plane of the support platform; two front and rear supporting inclined plates parallel to each other are fixedly installed on the top plane of the support platform; a jacking support platform is horizontally clamped between the upper ends of the two front and rear supporting inclined plates.

[0004] In the prior art, the pipe is pressed by two flipping plates on the support plate, but the pipe is located at the contact position of the support platform without a limit. The method of flipping and limiting the pipe with a single plate is not consistent for the center calibration and limit of the two pipes to be connected, resulting in unsatisfactory limit and calibration effects. The method of pressing the pipe by the plate makes the position of the pipe relatively fixed, and it is difficult to rotate the pipe to adjust the position of the port, resulting in many inconveniences in the connection construction process, and there is a certain room for optimization.
