At the same time, the heat transfer of the non-insulated brackets forms a temperature gradient on the steel brackets of the pipelines, which causes electrochemical corrosion and shortens the service life of the steel brackets.

DETAILED DESCRIPTION
[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0032] The bracket in the related technology not only loses energy by dissipating heat to the outside, but also acts as a thermal bridge to form a temperature gradient heat transfer field through the steel bracket in contact with it, and directly dissipates heat to the atmosphere; at the same time, the heat transfer of the non-insulated bracket forms a temperature gradient of the pipeline steel bracket, which causes electrochemical corrosion and shortens the service life of the steel bracket.
[0033] In order to solve the above technical problems, the present application proposes a low-friction thermal insulation guide bracket for cooperating with a steam pipe 200 , comprising two clamps 1 , a nano-wool layer 2 , two glass wool tube shells 3 and a guide assembly 4 .
[0034] The two clamps 1 are combined together to form a space for installing the steam pipe 200, and the nano-wool layer 2 is used to be sleeved on the side wall of the steam pipe 200; the two glass wool tube shells 3 correspond to the two clamps 1 one by one, and the two glass wool tube shells 3 have a first side surface and a second side surface opposite to each other, at least part of the first side surface is in contact with the inner side wall of the clamp 1, and at least the second side surface is in contact with the nano-wool layer 2; the guide assembly 4 is connected to one of the clamps 1 so that the clamp 1 can move along the axis of the steam pipe 200 and move laterally.
[0035] In this embodiment, the nano wool layer 2 is pre-wound around the side wall of the steam pipe 200. The nano wool layer 2 will improve the wear resistance and corrosion resistance of the steam pipe 200, improve the fluid flow characteristics in the steam pipe 200, and reduce energy loss. The glass wool tube shell 3 is then put on the surface of the nano wool layer 2, and finally the glass wool tube shell 3 is tightly fitted to the surface of the nano wool layer 2 through two clamps 1. The glass wool tube shell 3 has an extremely low thermal conductivity, which can effectively reduce the heat loss of the steam pipe 200 when conveying fluid, thereby improving energy utilization efficiency. Secondly, it can also increase the service life of the steel bracket. On the other hand, the glass wool tube shell has good buffering performance, which can reduce the amplitude of the oscillation of the steam pipe 200 and reduce the stress of the steam pipe 200, thereby protecting the steam pipe 200 from damage.
[0036] In this embodiment, the first side surface of the glass wool tube shell 3 completely covers the inner wall of the clamp 1 and extends axially along the steam pipe 200 to both ends of the clamp 1, so that the glass wool tube shell 3 can be completely fitted with the clamp 1 and can fully protect the clamp 1. Even if the steam pipe 200 is subjected to thermal expansion and contraction or other external forces, the glass wool tube shell 3 can still prevent the steam pipe 200 from contacting the clamp 1.
[0037] Similarly, the second side of the glass wool tube shell 3 is completely covered by the nano wool layer 2. It can be understood that when the nano wool layer 2 extends axially along the steam pipe 200 to both ends of the clamp 1 and is completely in contact with the glass wool tube shell 3, the heat insulation effect is optimal and the entire guide bracket can be effectively protected.
[0038] It should be understood that, in the present application, the guide bracket mainly moves along the axial direction of the steam pipe 200, and the lateral movement is a compensation amount, such as the thermal expansion and contraction of the steam pipe 200, which only has a small displacement in the lateral direction.
[0039] Furthermore, the guide assembly 4 includes a connecting frame 41 , a guide member 42 and a limiting member 43 .
[0040] The connecting frame 41 is connected to the clamp 1, specifically by welding or bolting, which will not be explained in detail here.
[0041] The guide member 42 is connected to the connecting frame 41; and
[0042] The limiting member 43 defines a guide groove 43 a , and the guide member 42 is located in the guide groove 43 a and can move along the axis of the steam pipe 200 and move laterally.
[0043] The guide groove 43a is distributed along the axial direction of the steam pipe 200, so the guide member 42 mainly moves along the axial direction of the steam pipe 200, but there is a certain gap between the guide member 42 and the two sides of the guide groove 43a. On the one hand, it is convenient for installation, and on the other hand, it provides compensation for thermal expansion and contraction of the steam pipe 200.
[0044] See also Figure 2 The guide member 42 includes a first tube support bottom plate 421 and a mirror stainless steel plate 422 which are connected to each other. The first tube support bottom plate 421 is connected to the connecting frame 41, specifically by welding or bolting. The mirror stainless steel plate 422 covers the first tube support bottom plate 421. In this way, when there is a lateral impact, the mirror stainless steel plate 422 has better impact resistance than the polytetrafluoroethylene plate 433 and is not easy to deform.
[0045] The limiting member 43 includes a second pipe support bottom plate 431 and a group of equilateral angle steels 432 relatively arranged on the second pipe support bottom plate 431. The second pipe support bottom plate 431 and the equilateral angle steels 432 define a guide groove 43a. A polytetrafluoroethylene plate 433 is provided at the bottom of the guide groove 43a. The second pipe support bottom plate 431 is integrally formed with the concrete pier by casting, thereby ensuring that the second pipe support bottom plate 431 has strong stability and is not easy to shake.
[0046] The mirror stainless steel plate 422 is fitted with the polytetrafluoroethylene plate 433, so when subjected to external force, the clamp 1, the nano wool layer 2, the glass wool tube shell 3, the steam pipe 200, the connecting frame 41, the first tube support bottom plate 421 and the mirror stainless steel plate 422 will slide relative to the polytetrafluoroethylene plate 433. When the mirror stainless steel plate 422 and the polytetrafluoroethylene plate 433 are in sliding contact, since both have a low friction coefficient and good wear resistance, efficient and stable sliding can be achieved.
[0047] In the embodiments of the present application, Figure 2 What is shown is only a schematic diagram. In fact, the gap between the mirror stainless steel plate 422 and the equilateral angle steel 432 is relatively small. On the one hand, the guide bracket can only move along the axial direction of the steam pipe 200. On the other hand, the existence of the gap will not affect the movement of the steam pipe 200. If the mirror stainless steel plate 422 and the equilateral angle steel 432 are fitted together, greater friction will be generated, affecting the axial movement of the guide bracket.
[0048] Furthermore, the mirror stainless steel plate 422 and the first tube support bottom plate 421 are welded by hot pressing, which can ensure the stability of the connection between the first tube support bottom plate 421 and the mirror stainless steel plate 422 and prevent them from falling off.
[0049] Please continue reading Figure 2 Along the axial direction of the steam pipe 200, flat iron blocks 434 are arranged on both sides of the polytetrafluoroethylene plate 433, and the flat iron blocks 434 are connected to the second pipe support bottom plate 431. The polytetrafluoroethylene plate 11 is welded and fixed to the second pipe support bottom plate 12 by the flat iron blocks 434, that is, the polytetrafluoroethylene plate 11 can be first connected to the flat iron blocks 434 by bolts, and the flat iron blocks 434 are then welded to the second pipe support bottom plate 12.
[0050] It should be understood that in the present application, the first tube support bottom plate 421 and the second tube support bottom plate 12 are both made of stainless steel, which has high strength and certain corrosion resistance.
[0051] Further, see Figure 2 A rib plate 435 is provided on one side of the equilateral angle steel 432 away from the guide groove 43 a , and the rib plate 435 is connected to the second pipe support bottom plate 431 .
[0052] Since the mirror stainless steel 422 will move laterally under the action of external force, the clamp 1, nano wool layer 2, glass wool tube shell 3, steam pipe 200, connecting frame 41, first pipe support bottom plate 421 and mirror stainless steel 422 will all collide with the equilateral angle steel 432. Therefore, in order to improve the stability of the equilateral angle steel 432, a rib plate 435 is provided on the side of the equilateral angle steel 432 away from the guide groove 43a. The cross-section of the rib plate 435 is a right-angled triangle, one right-angled surface is connected to the equilateral angle steel 432, and the other right-angled surface is connected to the second pipe support bottom plate 431. It is generally welded into an integrated manner to increase the strength.
[0053] like Figure 1-3 The two clamps 1 are detachably connected by bolts. This is a prior art, so no further explanation is given here. The detachable clamps 1 facilitate the early installation of the nano wool layer 2 and the glass wool tube shell 3.
[0054] This embodiment also provides a power transmission device, including:
[0055] The low-friction insulation guide bracket and steam pipe 200 of any of the above items, the steam pipe 200 is arranged between the two clamps 1. Since the functions and advantages of the low-friction insulation guide bracket have been described above, the power transmission device also has the above advantages, so that the life of the power transmission device is greatly improved.
[0056] Furthermore, along the axial direction of the steam pipe 200, the glass wool tube shell 3 extends to both sides of the clamp 1, and axial stop block groups are arranged on both sides of the glass wool tube shell 3, each axial stop block group includes a plurality of axial stop blocks 210, and the plurality of axial stop blocks 210 are welded to the steam pipe 200 at equal distances around the axis of the steam pipe 200.
[0057] Combination Figure 1 as well as Figure 2 From the perspective of FIG. 1 , the axial stopper 210 supports the glass wool tube shell 3 from both sides. When the steam pipe 200 moves, the axial stopper 210 pushes the glass wool tube shell 3 to move, so that the glass wool tube shell 3 can always cover the inner wall of the clamp 1 to prevent the clamp 1 from contacting the steam pipe 200.
[0058] It should be understood that, since the glass wool tube shell 3 extends to both sides of the clamp 1 , the axial stopper 210 will not contact the clamp 1 , thereby avoiding the generation of a thermal bridge.
[0059] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0060] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
