[0002] LNG pipeline refers to a pipeline specially used for transporting liquefied natural gas. LNG pipeline adopts efficient cold preservation technology to keep LNG at low temperature, so that LNG will not be gasified during transportation. At present, workers use cold insulation pipe supports to support and install LNG pipelines. Cold insulation pipe supports refer to a device used to support and protect the pipeline system. The purpose of cold insulation pipe supports is to provide thermal insulation performance, effectively control the pipeline temperature, and prevent energy loss or adverse effects of the external environment on the pipeline.

[0003] After searching, a patent document with patent announcement number CN212960205U discloses an adjustable cold-insulating pipe support, comprising a pipe support, an adjusting rod and a base, the adjusting rod comprising a fixed outer rod, a movable inner rod, a screw rod and a motor, a motor is arranged at the bottom of the fixed outer rod, the bottom of the movable inner rod is nested in the fixed outer rod, the top of the movable inner rod is fixedly connected to the bottom of the pipe support, a threaded hole begins to be arranged at the bottom of the movable inner rod, the bottom of the screw rod is fixedly connected to the output end of the motor, the top of the screw rod is arranged in the inner cavity of the movable inner rod through the threaded hole, a slide groove is arranged on the inner side of the upper pipe support, one end of the telescopic rod is fixedly connected to the top of the inner cavity of the slide groove, and the other end is arranged outside the slide groove and connected to a pressing plate, a compression spring is sleeved on the telescopic rod, and a first rubber pad is arranged on the inner wall of the lower pipe support, the beneficial effect is that the upper and lower positions of the pipe support are adjustable, and it can be applied to cooling pipes of different diameters, and it is highly practical.
