Specific implementation mode

[0031] Embodiment

[0032] As Figures 1-3 shown, a kind of pipeline heat tracing system, including multiple U-shaped groove prefabricated blocks 6 being arranged in straight line direction below ground, and the upper surface of U-shaped groove prefabricated block 6 is flush with ground, this kind of arrangement can ensure that the flatness of workshop ground, and the opening of U-shaped groove prefabricated block 6 is vertically arranged upwards, facilitate the arrangement of pipeline.

[0033] And to facilitate the installation and layout of oil pipe 1, the inner lower surface of U-shaped groove prefabricated block 6 is symmetrically provided with oil pipe support block 5 near the position of two sides, that is, the above-mentioned oil pipe 1 is arranged close to edge, so that the middle region can be reserved for other operations, and then oil pipe 1 is arranged above multiple oil pipe support blocks 5, to ensure that it has sufficient height;

[0034] Furthermore, the U-shaped groove prefabricated block 6 has symmetrically arranged air pipe support blocks 4 in the area between the two oil pipes 1. The air pipe support blocks 4 are also arranged to accommodate the oil pipes 1 located at a higher position, and the two air pipe support blocks 4 do not contact each other. That is to say, there is still space in the middle of the U-shaped groove prefabricated block 6 without other structures. The air pipe support blocks 4 are fixed with steam coils 2. For ease of installation and lower cost, the steam coils 2 are selected as flat-laid steam coils, which only need to be placed below or to the side of the oil pipes 1. Figure 6 As shown, however, considering the heating effect, you can also choose as follows: Figure 7 The illustrated series steam coil includes multiple U-shaped tubes arranged along the length of oil pipe 1, and the multiple U-shaped tubes are connected by horizontal pipes, with the effect as shown in the diagram. Figure 1 As shown, the heating effect is better.

[0035] Finally, based on the above structure, by reserving space, it can be done as follows: Figure 3 As shown, horizontal extension plates 61 extending horizontally towards the center are provided at the top of both sides of the U-shaped channel precast block 6, and the horizontal extension plates 61 are integrally formed with the U-shaped channel precast block 6. Then, the lower end of the filling precast block 7 abuts against the lower inner surface of the U-shaped channel, and the upper end abuts against and is parallel to the horizontal extension plates 61 to achieve the desired effect. Figure 3 As shown, the upper surface forms a plane, which will not affect the normal passage of personnel and vehicles in the factory. Furthermore, the aforementioned precast filling block 7, together with the U-shaped channel precast block 6, can form a transverse cavity structure. The cavity can be used to insulate the oil pipe 1 and steam coil 2 inside, and the insulation effect is better than the conventional method of setting a cover plate. In addition, the aforementioned precast filling block 7 or the U-shaped channel precast block 6 can also be made of insulation materials. The above method facilitates modular layout and also makes maintenance work convenient.

[0036] After that, as Figure 2 As shown, the specific arrangement of the above structure is as follows: the oil pipe support block 5 and the air pipe support block 4 are both inserted vertically relative to the U-shaped groove prefabricated block 6. This method facilitates disassembly and assembly and, while bearing the weight of the oil pipe 1 and the steam coil 2, will not cause them to fall out of their preset positions. In order to ensure that they can be installed normally, both of the above support blocks can pass through the gaps in the extension horizontal plate 61. In use, after the filling prefabricated block 7 is disassembled, the above support blocks can be installed. Furthermore, based on the above structure, in order to facilitate liquid drainage, the surfaces of the air pipe support block 4 and the oil pipe support block 5 are inclined. The inclined surfaces can be used to guide the liquid to flow towards the middle position. Therefore, in the event of any leakage, it can be detected in time after disassembling the filling prefabricated block 7.

[0037] It should be noted that in the above structure, in order to avoid mutual influence, the arrangement path of the two in the length direction of the pipeline is staggered, that is, even if the two support blocks are installed adjacent to each other, they will not affect each other, and the above air pipe support block 4 can also be arranged as a structure in which the two side surfaces are respectively attached to the oil pipe support block 5 and the filling prefabricated block 7, so as to ensure the stability of the structure.

[0038] Finally, as shown in Figure 4 , 5 In order to adapt to the actual situation of various application scenarios, the installation mode of the support block is that the U-shaped groove prefabricated block 6 can be provided with a vertical installation hole for arranging the oil pipe support block 5 or the air pipe support block 4 in the length direction, and the installation hole position ensures that the distance from the filling prefabricated block 7 is a constant value, and the installation hole position is arranged in a straight line.

[0039] In order to connect adjacent steam coils 2, the adjacent steam coils 2 are connected through a connecting hose 8, and the installation of the connecting hose 8 is more free and can be freely arranged. In order to facilitate maintenance, the steam coil 2 can pass through the distance between the self-extending horizontal plates 61, as shown in Figure 6 , 7 This way can ensure that the steam coil 2 is disassembled after the filling prefabricated block 7 is disassembled.

[0040] In addition, in order to facilitate the disassembly and assembly of the steam coil 2, the steam coil 2 is connected to the air pipe support block 4 through the locking seat 3, and the locking seat 3 includes two locking blocks symmetrically arranged in the horizontal direction, both of which are located in the same horizontal plane. The steam coil 2 is clamped and fixed by arranging a semicircular hole in the adjacent plane to form a circular hole, and a single locking block is fixed on the air pipe support block 4 by bolt insertion.

[0041] Finally, since the oil pipe 1 is supported by the oil pipe support block 5, in order to avoid affecting the installation of the steam coil 2, the oil pipe support block 5 includes a sliding support 51 in contact with the oil pipe 1 on the upper side. The sliding support 51 can move in the length direction of the oil pipe 1 and has a thickness less than the gap of the steam coil 2, as shown in Figure 1 It can support while not affecting normal installation, and the number of the above sliding supports 51 can be multiple.

[0042] As a preferred embodiment, as shown in Figure 3 In order to ensure the adaptability between the prefabricated blocks, the length of the U-shaped groove prefabricated block 6 is an integer multiple of the length of the filling prefabricated block 7, and the two ends of the filling prefabricated block 7 in the length direction are provided with vertical downward openings, so as to facilitate the disassembly of the filling prefabricated block 7.

[0043] Finally, the steam coil 2 is connected to the steam boiler, one end of the oil pipe 1 is connected to the oil tank, and the other end is connected to the oil pump.
