Description

Technical Field

[0001] The utility model relates to the technical field of pipeline hoisting devices, in particular to a municipal gas pipeline hoisting construction device. Background Art

[0002] Natural gas is a high-quality energy source that is close to environmental protection. It contains almost no sulfur, dust and other harmful substances. It produces less carbon dioxide when burned than other fossil fuels, so it can fundamentally improve the quality of the environment. In addition, natural gas has the advantages of being economical, safe and reliable. Natural gas is generally supplied by pipeline transportation. Natural gas pipeline transportation has the advantages of low transportation cost, small land occupation and fast construction. When maintaining the gas pipeline, the pipeline must be placed in the excavated ditch through a lifting device.

[0003] When the existing lifting rope mechanism is used to lift the pipeline, one method is to use a single rope to be set on the pipeline, and then lift the rope through a hook. After the pipeline is lifted into the excavated ditch, the pipeline and the soil at the bottom of the ditch are pressed together, and it is troublesome to pull the rope out from between the pipeline and the bottom of the ditch. Another method is to use a clamp to hold the pipeline, but when the clamp is released, the two clamping ends of the clamp need to be deflected to both sides to open, but the width of the ditch is limited, so when the clamp is opened, it is easy to interfere with the ditch. Therefore, when the width of the ditch and the pipeline is close, the clamp is not easy to use. Utility Model Content
