Description

TECHNICAL FIELD

[0001] The utility model belongs to pipeline heat preservation field, especially relate to a high altitude pipeline heat preservation structure. BACKGROUND

[0002] In the industrial pipeline engineering of large diameter and high altitude arrangement, the construction team often concentrates most of the attention on the installation link of the pipeline, and the preparation of the later heat preservation work is relatively neglected. This tendency of attention may seem reasonable at the beginning, because the installation of the pipeline is directly related to the structural integrity and function realization of the whole system, but in the long run, it has buried many hidden dangers. Especially when the pipeline is hoisted to the high altitude position, a series of complex and thorny problems will come one after another when starting the heat preservation process.

[0003] High altitude operation itself requires very high operation skill and strict safety measures, and laying, fixing and joint treatment of the heat preservation material in the narrow space for the large size pipeline is undoubtedly a great test of the professional skill of the construction team. It not only needs fine operation skill, but also requires the construction personnel to have good body coordination and high altitude operation experience to deal with various emergencies that may occur.

[0004] Secondly, the safety risk increases dramatically. High altitude operation itself is accompanied by high risk factors such as falling and object impact, and the debris and dust generated in the process of carrying, cutting and installing the heat preservation material further aggravates the danger of the operation environment. In addition to the stability problem of the high altitude operation platform and the potential impact of long time high altitude operation on the physical and mental health of workers, safety control becomes a very difficult task.

[0005] The neglect of the preparation of the heat preservation work in the industrial pipeline engineering of large diameter and high altitude arrangement will directly lead to a series of extremely unfavorable situations such as increased construction difficulty, upgraded safety risk, damaged engineering quality and increased engineering cost, which poses a serious threat to the overall benefit and long-term safe operation of the project. Therefore, how to heat the pipeline before high altitude pipeline installation is the key to ensure the smooth implementation and high quality completion of such projects. CONTENT OF THE UTILITY MODEL

[0006] The utility model intends to provide a high altitude pipeline heat preservation structure to solve the problem that the existing pipeline installation ignores the preparation work of the later heat preservation, and when the pipeline is hoisted to the high altitude and enters the heat preservation process, the construction difficulty, safety risk, engineering quality and engineering cost will all have extremely unfavorable problems.

[0007] The utility model discloses a high altitude pipeline heat preservation structure, including inner tube and outer tube, the outer tube is wrapped in the outer portion of inner tube, and contains the gap between inner tube and outer tube, the outer portion of outer tube is wrapped with the heat preservation layer, the lateral wall of outer tube is fixedly connected with a plurality of lugs, and a plurality of lugs extend outwardly through the heat preservation layer.

[0011] Further, one end of the lug extending out of the heat preservation layer is fixedly connected with a waterproof plate, and the waterproof plate is perpendicular to the lug. The waterproof plate shields the position of the lug extending out of the heat preservation layer, prevents rainwater from flowing into the gap of the heat preservation layer from the lug, separates the heat preservation layer from the outer tube, causes damage to the heat preservation layer, and reduces the heat preservation effect of the heat preservation layer.

[0012] Further, the inner tube and the outer tube are staggered, that is, one end of the outer tube extends out of the inner tube, and the other end is shorter than the inner tube. The staggered inner tube and outer tube facilitate the installation of the pipeline and the pipeline, and one of the two pipelines can be easily aligned with the recessed end of the inner tube of the other pipeline, facilitating installation.

[0013] Further, a plurality of reinforcing rings are arranged around the outer tube, the lug is fixedly connected to the lateral wall of the reinforcing ring, and the reinforcing ring is located inside the heat preservation layer. The reinforcing ring facilitates the installation of the lug, and the reinforcing ring can prevent the outer tube from deforming due to excessive stress during hoisting, further enhancing the practicability and service life of the pipeline.

[0014] Further, a through hole is arranged at the end of the lug away from the heat preservation layer, a shaft pin is sleeved in the through hole, the two ends of the shaft pin are detachably connected with the lug, and a lifting rope is sleeved in the lug. The lug facilitates the connection between the pipeline and the lifting rope, facilitating the lifting and installation of the pipeline. BRIEF DESCRIPTION OF DRAWINGS
