Description

Technical Field

[0001] The utility model relates to the technical field of heat tracing paving structures, in particular to a heat tracing paving structure for insulated heating cables. Background Art

[0002] The heat tracing paving structure of an insulated heating cable refers to installing the heating cable in a pipeline, equipment or space to be heated in a specific manner to achieve the purpose of heat tracing and heat preservation.

[0003] Common heat tracing paving structures generally need to set fixed points on the surface of the pipeline or equipment to ensure the stability and safety of the cable during operation, and use special fixing parts or tapes to fix the cable.

[0004] However, since the cable is generally installed outdoors and is affected by the ambient temperature, when the temperature of the cable changes, the cable will also thermally expand and contract. Long-term thermal cycling may cause the fixing parts to become loose, resulting in poor contact between the cable and the heating surface, which will reduce the heat transfer efficiency and make the heating effect poor. Content of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides a heat tracing paving structure for insulated heating cables to solve the problem that long-term thermal cycling may cause the fixing parts to become loose, resulting in poor contact between the cable and the heating surface, which will reduce the heat transfer efficiency and make the heating effect poor as mentioned in the above background art.

[0014] Preferably, control blocks are installed at the tops of the adjusting rods. The control blocks are all designed in a hexagonal shape, which is convenient for controlling the rotation of the adjusting rods.

[0015] Preferably, mounting brackets are installed at the bottoms of the lower mounting hoops. The mounting brackets are all designed in an L shape, and threaded rods are rotatably connected to the fronts of the mounting brackets. The mounting brackets can be installed through the threaded rods. When the insulated heating cable is applied outdoors, the insulated heating cable can be installed on the surface of the building through the mounting brackets.

[0028] The present utility model provides a technical solution, a heat tracing paving structure of an insulated heating cable. Please refer to Figure 1 , including a protective shell 1, and an electric tracing band 2 is installed on the inner wall of the protective shell 1;

[0029] Installation hoops 3 are arranged on both sides of the protective shell 1. There are two installation hoops 3 on the same side, and installation plates 4 are evenly distributed on the surface of the installation hoops 3;

[0030] Please refer to Figure 3 , adjusting rods 5 are arranged on the upper surface of the installation plates 4. The adjusting rods 5 are all rotationally connected to the surface of the installation plates 4, and positioning plates 6 are installed at the bottom ends of the adjusting rods 5 through bearings;

[0031] Slide rails 7 are arranged on both sides of the installation plates 4. The slide rails 7 are all connected to the surface of the installation hoops 3. Sliders 8 are installed on both sides of the installation plates 4, and the sliders 8 are all inserted into the interior of the slide rails 7;

[0032] The protective shell 1 can be installed on the surface of the cable through the installation hoop 3, so that the electric heating tape 2 can be stably installed. The rotation of the adjusting rod 5 can drive the positioning plate 6 to move towards the surface of the protective shell 1, so that the protective shell 1 can be squeezed, and thus the electric heating tape 2 can be squeezed, making the electric heating tape 2 in close contact with the surface of the cable, effectively preventing the phenomenon of poor contact between the electric heating tape 2 and the cable, and improving the heat transfer efficiency and heating effect.

[0033] Please refer to Figure 4 , connecting plates 9 are installed on both sides of the installation hoop 3. Please refer to Figure 2 , connecting rods 10 are rotatably connected between the connecting plates 9 on the same side. The connecting rod 10 passes through the upper connecting plate 9 and is rotatably connected to the surface of the lower connecting plate 9, so that the connecting plates 9 can be connected, and the installation hoop 3 can be firmly installed on the surface of the protective shell 1.

[0034] Please refer to Figure 3 , control blocks 11 are installed at the tops of the adjusting rods 5. The control blocks 11 are all designed as hexagons, which is convenient for controlling the rotation of the adjusting rods 5.

[0035] Please refer to Figure 5 , mounting brackets 12 are installed at the bottoms of the lower installation hoops 3. The mounting brackets 12 are all L-shaped. Threaded rods 13 are rotatably connected to the fronts of the mounting brackets 12. Through the threaded rods 13, the mounting brackets 12 can be installed. When the insulated heating cable is applied outdoors, the insulated heating cable can be installed on the surface of the building through the mounting brackets 12. When installed in the ground, the mounting brackets 12 can be installed in the installation grooves in the ground, so that the insulated heating cable can be installed more stably.

[0036] Fixing plates 14 are installed on the upper surfaces of the upper installation hoops 3. Bearing plates 15 are installed on the upper surfaces of the mounting brackets 12. The lower surfaces of the fixing plates 14 are in contact with the upper surfaces of the bearing plates 15. By connecting the fixing plates 14 and the bearing plates 15, the mounting brackets 12 can install the upper and lower installation hoops 3, improving the stability of the installation of the protective shell 1, and thus the insulated heating cable can be installed more firmly.

[0037] Fixing rods 16 are rotatably connected to the upper surfaces of the fixing plates 14. The lower parts of the fixing rods 16 are rotatably connected to the surfaces of the bearing plates 15. Removing the fixing rods 16 can separate the fixing plates 14 and the bearing plates 15, so that the upper and lower installation hoops 3 can be separated, facilitating the disassembly of the installation hoops 3.

[0038] The working process of this device is as follows: First, insert the connecting rod 10 through the upper connecting plate 9 and screw it onto the surface of the lower connecting plate 9, so as to connect the connecting plates 9 and firmly install the mounting hoop 3 on the surface of the protective shell 1. Then, through the mounting hoop 3, the protective shell 1 can be installed on the surface of the cable, and thus the electric heating tape 2 can be stably installed. Rotating the adjusting rod 5 can drive the positioning plate 6 to move towards the surface of the protective shell 1, so as to squeeze the protective shell 1 and then squeeze the electric heating tape 2, making the electric heating tape 2 closely contact the surface of the cable, effectively preventing the phenomenon of poor contact between the electric heating tape 2 and the cable, improving the heat transfer efficiency and heating effect. Finally, the mounting frame 12 can be installed through the threaded rod 13. When the insulated heating cable is applied outdoors, the insulated heating cable can be installed on the surface of the building through the mounting frame 12. When installed in the ground, the mounting frame 12 can be installed in the mounting groove in the ground, so as to more stably install the insulated heating cable. By connecting the fixing plate 14 and the receiving plate 15, the mounting frame 12 can install the upper and lower mounting hoops 3, improving the stability of the installation of the protective shell 1 and thus more firmly installing the insulated heating cable.
