Description

Technical Field

[0001] The invention relates to the technical field of heating belt application, and in particular to an electric heating belt capable of preventing movement and a method for preventing movement of the electric heating belt. Background Art

[0002] Heating tape, also known as electric heating tape, is a heating device that uses electrical energy to generate heat. It is mainly used to prevent pipes, containers or other equipment from freezing in low temperature environments, or to maintain the internal medium within a specific temperature range. It converts electrical energy into thermal energy by passing current through the resistance wire inside the heating tape, thereby achieving the purpose of heating.

[0003] Among the existing patent documents, there is a patent with publication number CN 116981118 A, entitled "A patent for an electric heating tape that prevents movement". Although this patent can restrict the heating tape to be fixed, thereby preventing the "movement" of the electric heating tape, it does not have a heat preservation function, resulting in the heat of the heating tape being easily lost after being heated; secondly, after the heating tape is fixed, it is impossible to disassemble a certain part or individually, resulting in relatively poor installation flexibility. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an electric heating tape that prevents movement and a method for preventing movement of the electric heating tape. By arranging a thermal insulation layer between the heating tape and the pipeline, the heat of the pipeline is not easily lost after being heated; secondly, by installing an anti-movement positioning frame, the wound heating tape can be fixed to effectively prevent the heating tape from "moving", wherein the anti-movement positioning frame can be freely installed or disassembled as needed, and is very flexible in application.

[0005] To solve the above technical problems, the technical solution of the present invention is achieved as follows:

[0006] An electric heating cable for preventing swaying, comprising a heating cable wound and fixed on the outside of a pipeline;

[0007] An insulation layer is arranged between the heating tape and the pipeline, and the insulation layer can completely wrap the outside of the pipeline;

[0008] The inner side of the thermal insulation layer is fixed with multiple inner positioning rings distributed in a linear array along its axial direction, and the thermal insulation layer is provided with multiple positioning through holes distributed in a circumferential array at the locations of the inner positioning rings, and the inner positioning rings are provided with positioning screw holes corresponding to the positions of the positioning through holes one by one;

[0009] An anti-channeling positioning frame for completely fixing the heating belt is installed in every two positioning through holes, and positioning sleeves are respectively connected to the two ends of the anti-channeling positioning frame. The positioning sleeves are equipped with screws that can be assembled in the positioning through holes and the positioning screw holes in sequence.

[0010] By adopting the above solution, an insulation layer is set between the heating tape and the pipeline, so that the heat of the pipeline is not easily lost after being heated; secondly, the wrapped heating tape can be fixed by installing an anti-channeling positioning frame, effectively preventing the heating tape from "channeling", and the anti-channeling positioning frame can be freely installed or disassembled as needed, and is very flexible in application.

[0011] As a preferred implementation of an electric heating tape for preventing movement, the material of the thermal insulation layer is thermal insulation sponge, and the material of the inner positioning ring is lightweight PVC.

[0012] By adopting the above scheme, in order to improve the thermal insulation effect and the supporting effect, a thermal insulation sponge is used to make the thermal insulation layer, wherein the thermal insulation layer is like a "thermal insulation coat"; a lightweight PVC is used to make an inner positioning ring, wherein the inner positioning ring is like a "support skeleton" and also plays the role of positioning the anti-collision positioning frame.

[0013] As a preferred implementation of an electric heating tape that prevents movement, a slot for limiting the position of the heating tape is provided at the bottom of the anti-movement positioning frame.

[0014] The above scheme is adopted to further improve the fixing effect of the heating belt, so that the anti-channeling positioning frame is tightened and the heating belt is connected by using the card slot, thereby strengthening the fixing effect of the heating belt.

[0015] As a preferred implementation of an electric heating tape for preventing movement, a stud is inserted above the screw, a rotatable anti-loosening seat is mounted on the stud, a docking groove is provided on one side of the anti-loosening seat, and anti-loosening rod heads are placed in the docking grooves of the two anti-loosening seats; wherein, both ends of the anti-loosening rod head are respectively interference fitted in the docking grooves.

[0016] By adopting the above scheme, in order to prevent the anti-loosening positioning frame from falling off due to loosening of the screws, the anti-loosening seat is rotated and the direction of the docking groove is adjusted so that the docking grooves of the two anti-loosening seats are opposite to each other, and the two ends of the anti-loosening rod head are respectively placed in the docking groove. At this time, under the joint connection of the anti-loosening rod heads, the two anti-loosening seats are not easy to loosen.

[0017] As a preferred implementation of an electric heating tape for preventing movement, a locking nut capable of tightening an anti-loosening seat is provided on the stud through a thread; wherein the locking nut and the upper and lower surfaces of the anti-loosening seat are provided with anti-slip portions, such as anti-slip grooves.

[0018] By adopting the above scheme, in order to improve the tightening effect of the locking nut on the anti-loosening seat, the friction between the locking nut and the surface of the anti-loosening seat is increased, which can effectively improve the effect of the locking nut after self-locking.

[0019] As a preferred implementation of an electric heating tape that prevents movement, a hexagonal plug is fixed to the lower end of the stud, and the end of the screw is provided with an inner hexagonal hole for use with the hexagonal plug; wherein the hexagonal plug is interference-fitted into the inner hexagonal hole.

[0020] By adopting the above scheme, in order to quickly realize plug-in assembly, the hexagonal plug of the stud is directly plugged into the hexagonal hole during application. At this time, the stud and the screw are integrated, and the disassembly and assembly are convenient and easy.

[0022] S1. Wrap the insulation layer and the inner positioning ring around the outside of the pipe, and then wind the heating tape around and fix it on the insulation layer;

[0023] S2. To prevent the heating tape from "moving", install screws in the positioning sleeves at both ends of the anti-moving positioning frame, and install the screws in the positioning through holes and positioning screw holes in turn, and completely lock the heating tape;

[0026] S5. Finally, fix the locking nut on the stud through threads. The anti-loosening seat can be completely tightened by the locking nut. At this time, under the joint connection of the anti-loosening rod heads, the two anti-loosening seats are not easy to loosen.

[0027] After adopting the above technical solution, the beneficial effects of the present invention are:

[0028] 1. By setting an insulation layer between the heating tape and the pipeline, the heat of the pipeline is not easy to dissipate after being heated; secondly, by installing an anti-channeling positioning frame, the wrapped heating tape can be fixed to effectively prevent the heating tape from "channeling". The anti-channeling positioning frame can be freely installed or disassembled as needed, and it is very flexible in application;

[0029] 2. In order to improve the thermal insulation effect and the supporting effect, the thermal insulation layer is made of thermal insulation sponge, which is like a "thermal insulation coat"; the inner positioning ring is made of lightweight PVC, which is like a "support skeleton" and also plays the role of anti-channeling positioning frame positioning;

[0030] 3. In order to further improve the fixing effect of the heating tape, the anti-channeling positioning frame is tightened and the heating tape is connected using the card slot, thereby strengthening the fixing effect of the heating tape;

[0031] 4.
