Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present application, embodiments of the present application will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

Based on the prior art that large-scale long distance heat supply pipeline lacks effective heat insulation measure, and external heat preservation structural volume and structural weight are too big, and the thermal-insulated effect is not good and installation and maintenance are difficult, this application provides an improved pipeline heat insulation support, as shown in fig. 1-4.

Referring to the attached drawings, the pipeline heat insulation support is used for supporting a heat supply pipeline 1 above a supporting beam 7 and comprises a heat insulation pad 5, a support 2 which is arranged above the heat insulation pad 5 and used for supporting the heat supply pipeline 1, and a lower bottom plate 8 arranged below the heat insulation pad 5; the lower floor plate 8 is fixed to the support beam 7 by a lower support plate 9. In order to improve the heat insulation effect, the heat insulation pad 5 may preferably be made of soft and fluffy heat insulation material, such as aerogel-filled flexible heat insulation material.

The support bottom plate 21 is arranged below the support 2, and the heat insulation pad 5 is clamped between the support bottom plate 21 and the lower bottom plate 8. The support bottom plate 21 and the lower bottom plate 8 are connected together by bolts 3 penetrating through the heat insulating and preserving mat 5. Because most heat preservation materials do not have enough intensity, the support bottom plate 21 and the lower bottom plate 8 are connected through four bolts 3, the distance tube 4 is arranged between the support bottom plate 21 and the lower bottom plate 8, the bolts 3 penetrate through the distance tube 4 to keep the distance between the support bottom plate 21 and the lower bottom plate 8 unchanged, and the distance and the intensity requirements between the support bottom plate 21 and the lower bottom plate 8 are kept through the distance tube 4. In order to reduce the heat transfer between the bolt 3 and the heat insulation pad 5, the gap between the bolt 3 and the distance tube 4 can be filled with low-density polyurethane filler for heat insulation.

An arc-shaped supporting plate 22 for supporting the heat supply pipeline 1 is arranged above the bracket 2. The heat supply pipeline 1 can be supported by the arc-shaped supporting plate 22 in a sliding way under the condition of thermal expansion and cold contraction deformation of the heat supply pipeline 1. The arc-shaped supporting plate 22 is connected with the bracket bottom plate 21 through a vertical rib plate 23.

Further, as shown in the figure, two support limiting blocks 6 are fixedly mounted on the lower supporting plate 9, and the support limiting blocks 6 are arranged in the directions of two sides of the heat supply pipeline 1 to clamp the heat insulation pad 5 between the two support limiting blocks 6. In order to reduce the stress when the pipeline is thermally expanded, sliding heat insulation gaskets can be arranged between the upper head part and the lower head part of the bolt 3 and the contact surfaces, the sliding heat insulation gaskets can be made of polytetrafluoroethylene, and the structural stress when the support slides along with the thermal expansion of the pipeline can be reduced while the support is thermally insulated.
