Description

Technical Field

[0001] The present application relates to the field of petroleum technology, and in particular to a petroleum pipeline trench hoisting device. Background Art

[0002] Petroleum is a dark brown viscous oily liquid with green fluorescence and a special smell. It is a mixture of various liquid hydrocarbons such as alkanes, cycloalkanes, aromatic hydrocarbons and olefins. After refining and processing, various fuel oils, solvent oils, lubricating oils, greases, paraffin, asphalt, liquefied gas, aromatic hydrocarbons and other products can be obtained, providing fuel, raw materials and chemical products for various sectors of the national economy. When laying oil transportation pipelines, if pipeline trenching construction is required, oil pipeline trenching lifting equipment is required to lay the pipeline.

[0003] For example, a Chinese utility model patent with publication number "CN217867751U" discloses a pipeline lifting device. The utility model has a winding frame fixedly installed on both sides of the top of the top plate, and the lifting chain is arranged along two support rods distributed in a Y shape with the top plate, so that the device uses two casing rings when lifting a pipeline, thereby making the pipeline force balanced, avoiding the phenomenon of pipeline tilting due to unbalanced center of gravity of the pipeline, and the driving gear is meshed with two driven gears. When the driving motor is working, the two winding frames release or reel in the wire at the same speed at the same time, so that the two ends of the pipeline between the two casing rings move upward or downward at the same time, avoiding the phenomenon of pipeline tilting due to inconsistent speed.

[0004] In the above patent, the pipeline can be lifted to facilitate the installation of the pipeline, but the device is difficult to adjust the position of the pipeline after lifting. If the pipeline is to be laid in the trench, it is difficult to lift the pipeline and move it into the trench, which can easily affect the pipeline laying work. Utility Model Content
