Problems solved by technology
There are deficiencies in the safety, reliability and aesthetics of the project after installation, which has become a major problem that plagues the construction quality of thermal pipelines in construction and installation projects.
At the same time, due to the change of ambient temperature, the pipeline will not only produce thermal expansion and contraction in the longitudinal direction, but also produce vertical bending deformation, and the thermal expansion and contraction caused by temperature difference will cause sliding friction between the guide rib and the casing, which will cause serious wear to the casing; friction When the obstruction is severe, the shear force between the guide ribs and the core tube may even cause the core tube to rupture

Embodiment Construction
[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0014] as 1 to image 3 As shown, the vertical heat pipe guide bracket includes a core tube 1 , a sleeve 2 sleeved outside the core tube 1 , a guide rib 3 , a pulley 4 , and a fixing seat 7 . Wherein, an insulating layer (not shown in the figure) filled with insulating material is arranged between the core pipe 1 and the sleeve pipe 2 . The length of the sleeve pipe 2 is two and a half times the thermal displacement of the core tube 1. The equation is as follows: L=2.5×ΔL, where ΔL is the thermal displacement of the core tube 2. In the present embodiment, the length L of the core tube 1 is 600mm, and the length of casing 2 is 300mm.
[0015] Such as figure 2 and image 3 As shown, the guide rib 3 includes two parallel fixed plates 5 and a pulley shaft 6, one end of the fixed plate 5 is welded on the outer wall of the core tube 1, and the ...

The invention relates to a vertical heating power pipe guide bracket, including a core tube and a casing sleeved outside the core tube, which is characterized in that, the outerwall of the core tube is provided with a guide floor, of which the outer end is provided with pulleys, wherein the pulleys bunt against the inwall of the case. The design of the guide floor is convenient for the core tube and the case to install and maintain, meanwhile the removal of the core tube caused by expand when hot and contract when cold is changed from the sliding friction to the rolling friction, which reduces the hot loss, avoids the friction damage, due to the guide action of the guide floor, the vertical flexural displacement of the core tube is greatly reduced, the operation of the heating power tube is stable and reliable, and the heat insulation effect is good.
Description
technical field [0001] The invention relates to a pipe fitting, in particular to a guide bracket for a vertical heat pipe. Background technique [0002] In power stations or civil buildings, according to the practice in the standard atlas "05R417-1", the traditional heat pipe support is usually limited to the concrete pier or the steel support of the building frame structure by angle iron or steel plate. According to this approach, the setting and installation of the vertical heat pipe guide sliding bracket greatly increases the difficulty of installation and maintenance. There are deficiencies in the safety, reliability and aesthetics of the project after installation, which has become a major problem that plagues the construction quality of thermal pipelines in construction and installation projects. At the same time, due to the change of ambient temperature, the pipeline will not only produce thermal expansion and contraction in the longitudinal direction, but also produ...
