Description

Technical Field

[0001] The present invention relates to the technical field of heating cables, and in particular to a heating cable installation method and a laying device. Background Art

[0002] In the industrial and energy fields, pipeline systems are often used to transport liquids or gases, especially in the oil, chemical and natural gas industries. These pipelines are susceptible to heat loss in low temperature environments, causing the fluid viscosity to increase or even solidify, thus affecting the normal operation of the pipeline. In order to solve this problem, heat tracing systems are widely used for pipeline insulation and antifreeze.

[0003] Traditional heating cable laying methods have some technical problems, such as low heat transfer efficiency, uneven heat distribution, and easy cable damage. These problems not only reduce the performance of the heating system, but also increase maintenance costs and safety risks. For example, if the heating cable is not laid properly, it may cause local overheating or overcooling of the pipeline, which in turn may cause thermal stress damage to the pipeline material or thermal expansion of the fluid, affecting the stability and reliability of the entire pipeline system.

[0004] In addition, the laying and fixing method of the heating cable also has an important impact on the long-term performance of the system. Improper laying methods may cause the cable to be loosely fixed on the pipeline. As time goes by and environmental conditions change, the cable may shift or fall off, especially when the heating cable is installed in a "U" shape, which is more likely to cause displacement and affect the effective transfer of heat energy. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] In view of the above-mentioned problems of low efficiency of existing heat energy transfer and uneven heat distribution, the present invention is proposed.

[0007] Therefore, an object of the present invention is to provide a method for installing a heating cable.

[0008] To solve the above technical problems, the present invention provides the following technical solutions: first, determine the 45° angle range where the lower half of the pipe cross section intersects with the vertical center line as the main laying area of ​​the heating cable; within the 45° angle range, lay the heating cable along the length direction of the pipe;

[0009] Adjust the laying path of the heating cable to avoid laying it in the upper part of the pipeline and within the 135° angle that intersects the vertical center line.

[0010] As a preferred solution of the heating cable installation method of the present invention, when multiple heating cables need to be laid in parallel, ensure that the spacing between each cable is uniform and there is no overlap or crossing between the cables to ensure uniform heat distribution and avoid cable damage.

[0011] As a preferred solution of the heating cable installation method of the present invention, the heating cable is laid in a segmented reverse spiral manner, wherein both ends of the spiral and the middle end section are tied and fixed with cable ties.

[0012] As a preferred solution of the heating cable installation method of the present invention, the winding spacing "S" of the heating cable is strictly implemented in accordance with the provisions in the design instructions.

[0013] As a preferred solution of the heating cable installation method of the present invention, when the heating cables are bundled and fixed with cable ties, the maximum bundling spacing of the cable ties does not exceed 300 mm.

[0014] The beneficial effects of the present invention are as follows: first, the method optimizes the heat transfer path by laying the heating cable within the range of 45° where the lower half section of the pipeline intersects the vertical center line, so that the heat can be transferred to the pipeline more directly and effectively, thereby improving the heat transfer efficiency. This laying method reduces the loss of heat during the transfer process and ensures that the fluid in the pipeline can still maintain good fluidity in a low temperature environment.

[0015] Secondly, this method ensures uniform distribution of heat along the pipeline through evenly spaced parallel laying and segmented reverse spiral laying. This laying method avoids the problem of heat concentration or insufficient heat, helps maintain the stability of the fluid temperature in the pipeline, and prevents pipeline stress and potential damage caused by excessive temperature differences.

[0016] In order to solve the problem that the above-mentioned heating cable is more likely to be displaced when installed in a "U" shape, the present invention also provides a heating cable laying device, including a heating cable installation method, and also includes a main body mechanism, including a pipeline and a heating cable; a fixing mechanism, including a rolling belt and a positioning assembly arranged on the rolling belt, the rolling belt is used to fix the heating cable to the outer wall of the pipeline, and the positioning assembly is used to fix the relative position of the heating cable and the rolling belt.

[0017] As a preferred solution of the heating cable installation method described in the present invention, the positioning assembly includes a first clamping member and a second clamping member, and the first clamping member and the second clamping member are connected by a connecting rod; one end of the connecting rod is fixedly connected to the rolling strip, and the other end of the connecting rod is fixedly connected to the second clamping member.

[0018] As a preferred solution of the heating cable installation method of the present invention, the positioning components are all "U"-shaped openings, and the positioning components are elastic.

[0019] As a preferred solution of the heating cable installation method of the present invention, the first engaging member includes a first clamp and a second clamp, and the first clamp and the second clamp are both arranged on the rolling strip.

[0020] As a preferred solution of the heating cable installation method of the present invention, the first engaging member is connected to the second engaging member through the connecting rod, and the first engaging member, the connecting rod and the second engaging member together form a "T" shape.

[0021] The beneficial effects of the present invention are as follows: the relative positions of the two vertical cables of the "U"-shaped heating cable and the pipeline are fixed by the first clamp on the rolling strip and the second clamp, and then the arc-shaped part of the "U"-shaped heating cable is fixed by the second clamp. Such an arrangement can solve the problem that the heating cable is more likely to be displaced when it is installed in a "U" shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a method for installing a heating cable 102, including first determining a 45° angle range where the lower half section of the pipeline 101 intersects with the vertical center line as the main laying area of ​​the heating cable 102; within the 45° angle range, laying the heating cable 102 along the length direction of the pipeline 101 to ensure that the cable is in close contact with the surface of the pipeline 101; adjusting the laying path of the heating cable 102 to avoid laying in the upper half of the pipeline 101 and within the 135° angle range intersecting with the vertical center line, so as to reduce heat loss and improve thermal efficiency.

[0034] Specifically, when multiple heating cables 102 need to be laid in parallel, ensure that the spacing between each cable is uniform and that there is no overlap or crossing between the cables to ensure uniform heat distribution and avoid cable damage.

[0035] The cable is laid in a segmented reverse spiral manner, wherein both ends and the middle end section of the spiral are tied and fixed with cable ties to ensure the stability of the cable on the pipe 101, and the fixed spacing of the remaining parts is appropriately adjusted according to actual conditions to adapt to the geometric shape and thermal expansion characteristics of the pipe 101.

[0036] Furthermore, the winding spacing "S" of the heating cable 102 is strictly implemented in accordance with the provisions of the design specifications to ensure uniform heating of the cable and avoid overheating, while ensuring the service life of the cable.

[0037] Furthermore, when the heating cable 102 is bundled and fixed with a cable tie, the maximum bundling spacing of the cable tie does not exceed 300 mm, so as to ensure the fixing strength and stability of the cable and avoid damage to the cable.

[0038] First, the construction team determined the main laying area of ​​the heating cable 102 within the 45° angle between the lower half of the pipe 101 and the vertical center line. The selection of this area was based on comprehensive considerations of heat transfer efficiency and the safety of the pipe 101. In this area, the heating cable 102 was evenly laid along the length of the pipe 101 to ensure that the cable fits tightly against the surface of the pipe 101, thereby maximizing the efficiency of heat transfer.

[0039] In the case of multiple heating cables 102 being laid in parallel, the construction team ensured that the spacing between each cable was even and that overlapping or crossing of the cables was avoided. This step is critical to ensuring even distribution of heat and preventing the cables from being damaged by squeezing each other.

[0040] In order to further improve the laying stability and adapt to the thermal expansion characteristics of the pipeline 101, the segmented reverse spiral method is used for laying. The two ends and the middle end of the spiral are tied and fixed with cable ties. This bundling method not only ensures the stability of the cable on the pipeline 101, but also allows the fixed spacing in the remaining parts to be appropriately adjusted according to actual conditions to adapt to the geometric shape and thermal expansion characteristics of the pipeline 101.

[0041] In controlling the winding spacing, the construction team strictly followed the "S" value specified in the design instructions to ensure uniform heating of the cable and avoid overheating, thereby extending the service life of the cable.

[0042] Finally, when using cable ties to tie and fix the heating cable 102, the construction team ensured that the maximum bundling spacing of the cable ties did not exceed 300mm. This measure not only ensured the fixing strength and stability of the cable, but also avoided damage to the cable, ensuring the reliability and long life of the entire heating system.

[0043] Example 2, reference Figures 4 to 5This embodiment is different from the first embodiment in that: a main body mechanism 100 includes a pipeline 101 and a heating cable 102; a fixing mechanism 200 includes a rolling belt 201 and a positioning assembly 202 arranged on the rolling belt 201, the rolling belt 201 is used to fix the heating cable 102 on the outer wall of the pipeline 101, and the positioning assembly 202 is used to fix the relative position of the heating cable 102 and the rolling belt 201.

[0044] Specifically, the positioning assembly 202 includes a first engaging member 202a and a second engaging member 202b, and the first engaging member 202a and the second engaging member 202b are connected by a connecting rod 202c; one end of the connecting rod 202c is fixedly connected to the rolling strip 201, and the other end of the connecting rod 202c is fixedly connected to the second engaging member 202b. It should be noted that the positioning assembly 202 is used to fix different parts of the cable, especially the "U"-shaped part, to prevent the cable from sliding or falling off on the pipe 101.

[0045] Furthermore, the positioning components 202 are all in a "U"-shaped opening shape, and the positioning components 202 are elastic.

[0046] The rest of the structure is the same as that of Example 1.

[0047] Example 3, reference Figures 1 to 5 This embodiment is different from the above embodiments in that the first engaging member 202a includes a first clamp 202a - 1 and a second clamp 202a - 2 , and both the first clamp 202a - 1 and the second clamp 202a - 2 are arranged on the rolling strip 201 .

[0048] Specifically, the first engaging member 202a includes a first clamp 202a - 1 and a second clamp 202a - 2 , and the first clamp 202a - 1 and the second clamp 202a - 2 are both disposed on the rolling strip 201 .

[0049] The rest of the structure is the same as that of Example 2.

[0050] It should be noted that during the long-term use of the heating cable 102, the "U"-shaped portion is more likely to be displaced than the straight portion, thereby affecting the heat transfer. The rolled strip 201 in the prior art simply holds the heating cable 102 and the pipe 101 together, and there is no better way to fix the "U"-shaped portion of the heating cable 102.

[0051] In our invention, the first engaging member 202a is connected to the second engaging member 202b through the connecting rod 202c, so that the first engaging member 202a, the connecting rod 202c and the second engaging member 202b together form a "T" shape, wherein the first clamp 202a-1 and the second clamp 202a-2 can fix the straight portion of the heating cable, and the second positioning component 202 can fix the U"-shaped portion of the heating cable, thereby solving the problem that the "U"-shaped portion of the heating cable is more easily displaced than the straight portion, thereby affecting the heat energy transfer.

[0052] Operation process: When the heating cable 102 is connected to the pipeline 101 through the rolling belt 201, due to the needs of actual use, the heating cable 102 will not be laid in a straight line all the time, but there will be a loop. If there is a loop, the heating cable 102 will have a "U" shape. When encountering a "U"-shaped part of the heating cable, firstly, the first clamp 202a-1 and the second clamp 202a-2 on the rolling belt 201 are simultaneously engaged with the straight part of the heating cable, and then the second fixing piece is engaged with the arc of the "U"-shaped part of the heating cable, and then the rolling belt 201 is tightened and fixed, and then the other parts of the heating cable can be connected to the pipeline 101 through other types of rolling belts 201.

Therefore, the invention is not limited to a specific embodiment, but extends to several modifications still falling within the scope of the appended claims.
