Description

Technical Field

[0001] The utility model belongs to the technical field of pipelines, and particularly relates to a cold-insulating pipe support capable of fixing LNG pipelines of different sizes. Background Art

[0002] Pipeline refers to a device used to transport materials over long distances, such as gas materials, particulate materials, and liquid materials, and LNG pipelines belong to the category of pipelines. LNG pipelines refer to pipelines specifically used to transport liquefied natural gas, and during the installation of LNG pipelines, cold-insulated pipe supports will be used to fix and support the LNG pipelines. The cold-insulated pipe supports mainly consist of arc-shaped upper brackets, arc-shaped lower brackets, bolts, nuts, and installation frames.

[0003] After searching, a patent document with patent announcement number CN207213339U discloses a cold-keeping pipe support suitable for pipes of different sizes, including a pipe support base, a mounting column fixed on the top of the pipe support base, a plurality of slider limit holes with equal spacing are opened on the mounting column, and a support column mounting slider is wrapped on the outside of the mounting column, two lower bracket support columns and a spring shock absorber are installed on the top of the support column mounting slider, and the spring shock absorber is located between the two lower bracket support columns, the tops of the two lower bracket support columns are connected to the lower bracket, the upper bracket connected to the lower bracket by a fixed threaded rod is located above the lower bracket, and the lower bracket and the upper bracket form a circular ring structure, and the inner side walls of the lower bracket and the upper bracket are elastically connected with four cold-keeping blocks respectively through four springs. The utility model is provided with a spring, and the provided spring is used to fix the cold-keeping blocks respectively between the upper bracket and the lower bracket, and pipes of different sizes can change the caliber of the pipe support by squeezing the spring.

[0004] However, it still has the following disadvantages in actual use:

[0005] The existing cold-insulation pipe brackets suitable for pipes of different sizes, during use, fix and support the LNG pipe by setting the lower bracket and the upper bracket, and lock and connect the upper bracket and the lower bracket by turning multiple bolts to fix the LNG pipe, but the operation steps are increased, which increases the workload of the staff;

[0006] 2. The existing cold-insulation pipe supports suitable for pipelines of different sizes have a support frame arranged on the lower surface of the lower bracket during use, so that there is a certain distance between the lower bracket and the ground, so that the fixed LNG pipeline is at a distance from the ground, but the shockproof effect on the fixed LNG pipeline is not good, and the LNG pipeline has a large impact force with the upper bracket or the lower bracket due to the large vibration amplitude, which reduces the protection effect of the LNG pipeline.

[0007] To this end, we provide a LNG pipeline cold-insulation pipe support that can fix different sizes to solve the above problems. Utility Model Content
