Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable protection pipe processing technology, and in particular to a processing device for MPP cable protection pipe socket interface. Background Technology
[0002] In the field of power engineering, MPP cable protection pipes are widely used in cable laying projects due to their excellent electrical insulation properties, high mechanical strength, and corrosion resistance. The socket joint of MPP cable protection pipes is a common connection method, which involves inserting one end of one pipe into the flared end of another pipe to achieve the connection. This joint method is relatively simple to operate, provides good sealing, and effectively prevents external substances from corroding the cable, ensuring the safe operation of the cable.
[0003] However, the heating process is crucial in the fabrication of socket joints for MPP cable protection pipes. Taking the relevant technology in patent application CN202222543473.9 as an example, the heating method used in this technology has certain shortcomings in practical application. Its heating plate can only heat the pipe from the outside, leading to uneven heating. Due to the material characteristics of MPP cable protection pipes, uniform heating is a key factor in ensuring the pipe expansion effect during socket joint fabrication. When heating is uneven, different parts of the pipe will have different temperatures. Areas that are heated too much may soften excessively, easily leading to excessive deformation during expansion; while areas that are not heated enough will not soften sufficiently, failing to achieve the expected expansion effect, thus affecting the overall quality of the socket joint fabrication. This may not only reduce the sealing performance of the joint but also affect the overall strength and stability of the pipe after connection, posing a potential threat to the safety and reliability of cable laying projects. Therefore, developing a device that can achieve uniform heating and improve the quality of socket joint fabrication is of significant practical importance. Utility Model Content
[0004] The main purpose of this utility model is to provide a processing device for the socket-type interface of MPP cable protection pipe, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A processing device for MPP cable protection pipe socket interfaces includes a workbench. A mounting base is fixedly installed on the upper end of the workbench. A support base is fixedly installed on one end of the mounting base. A drive assembly is fixedly installed on the lower end of the support base. The drive assembly consists of a drive motor, a rotating connecting plate, and a drive cylinder. The rotating connecting plate is fixedly installed on the output shaft of the drive motor. The drive cylinder is fixedly installed on the rotating connecting plate. A heating assembly is fixedly installed on the piston rod of the drive cylinder. The heating assembly consists of an outer heating pipe, an inner heating pipe, a first arc-shaped connecting plate, a second arc-shaped connecting plate, a connecting base ring, and a Z-shaped connecting plate. The inner heating pipe is located inside the outer heating pipe. The first arc-shaped connecting plate is fixedly installed on one end of the outer heating pipe, the second arc-shaped connecting plate is fixedly installed on one end of the inner heating pipe, the connecting base ring is fixedly installed on one end of the first and second arc-shaped connecting plates, and the Z-shaped connecting plate is fixedly installed on the outer wall of the connecting base ring.
[0007] Preferably, a flaring assembly is fixedly mounted on the mounting base plate, a pressing assembly is fixedly mounted on the support base plate, and a support assembly is fixedly mounted on the upper end of the equipment worktable, with the support assembly located directly below the pressing assembly.
[0008] Preferably, the drive motor on the drive assembly is fixedly mounted on the lower end of the support base plate.
[0009] Preferably, the Z-shaped connecting plate on the heating assembly is fixedly mounted on the piston rod of the drive cylinder.
[0010] Preferably, the outer heating tube and the inner heating tube on the heating assembly are coaxial.
[0011] Preferably, the heating assembly has four first arc-shaped connecting plates and four second arc-shaped connecting plates. The four first arc-shaped connecting plates are symmetrically fixedly installed at one end of the outer heating tube, and the four second arc-shaped connecting plates are symmetrically fixedly installed at one end of the inner heating tube.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] (1) By setting up a heating assembly consisting of an outer heating pipe, an inner heating pipe, a first arc-shaped connecting plate, a second arc-shaped connecting plate, a connecting base ring, and a Z-shaped connecting plate, the inner heating pipe is located inside the outer heating pipe. When heating the MPP cable protection pipe, the inner heating pipe heats from inside the pipe, and the outer heating pipe heats from outside the pipe. This allows the inner and outer walls of the pipe to be heated simultaneously, effectively solving the problem of uneven heating of the pipe caused by the traditional single external heating method. After the pipe is heated evenly, the softening degree of each part is consistent during the subsequent expansion process, avoiding the situation of local over-softening or under-softening caused by uneven heating. This ensures the processing quality of the socket joint, improves the sealing performance of the joint and the overall strength and stability of the pipe after connection, and reduces the potential threat to the safety and reliability of the cable laying project.
[0014] (2) By setting up a drive assembly and installing the heating assembly on the drive assembly, the drive motor drives the rotating connecting plate to rotate, and the drive cylinder can control the extension and retraction of the heating assembly, thereby realizing the automatic movement of the heating assembly in the horizontal and vertical directions. This not only improves the efficiency of the connection between the heating assembly and the cable protection pipe during the processing, and reduces the time and effort consumed by manual operation, but also controls the position of the heating assembly more accurately, so that the heating assembly can accurately heat the parts of the MPP cable protection pipe that need to be processed, further ensuring the uniformity and stability of heating, and providing strong support for improving the processing quality of the socket interface.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an MPP cable protection pipe socket interface processing device includes a workbench 1. A mounting base plate 2 is fixedly mounted on the upper end of the workbench 1. A support base plate 3 is fixedly mounted on one end of the mounting base plate 2. A drive assembly 4 is fixedly mounted on the lower end of the support base plate 3. The drive assembly 4 consists of a drive motor 9, a rotating connecting plate 10, and a drive cylinder 11. The rotating connecting plate 10 is fixedly mounted on the output shaft of the drive motor 9. The drive cylinder 11 is fixedly mounted on the rotating connecting plate 10. A heating assembly 5 is fixedly mounted on the piston rod of the drive cylinder 11. The heating assembly 5 consists of an outer heating pipe 12, an inner heating pipe 13, a first arc-shaped connecting plate 14, a second arc-shaped connecting plate 15, a connecting base ring 16, and a Z-shaped connecting plate 17. The device consists of an inner heating tube 13 located inside an outer heating tube 12. A first arc-shaped connecting plate 14 is fixedly installed at one end of the outer heating tube 12, a second arc-shaped connecting plate 15 is fixedly installed at one end of the inner heating tube 13, a connecting base ring 16 is fixedly installed at one end of the first arc-shaped connecting plate 14 and the second arc-shaped connecting plate 15, a Z-shaped connecting plate 17 is fixedly installed on the outer wall of the connecting base ring 16, a flaring assembly 6 is fixedly installed on the mounting base 2, a pressing assembly 7 is fixedly installed on the support base 3, and a support assembly 8 is fixedly installed at the upper end of the equipment workbench 1, located directly below the pressing assembly 7. When using this MPP cable protection tube socket interface processing device, the MPP cable protection tube is first placed on the support assembly 8, and simultaneously... Figure 1As shown, a portion of the MPP cable protection tube is positioned inside the support assembly 8. Then, the pressing assembly 7 is activated to press and fix the MPP cable protection tube onto the support assembly 8. Next, the drive motor 9 is activated, causing the rotating connecting plate 10 to rotate, thereby adjusting the horizontal position of the heating assembly 5 so that it aligns with the area of the cable protection tube to be processed and is coaxial with the cable protection tube. Then, the drive cylinder 11 is activated, pushing the piston rod out and bringing the heating assembly 5 closer to the cable protection tube, so that the outer heating tube 12 is fitted onto the outside of the cable protection tube, and the inner heating tube 13 is inserted into the cable protection tube. At this point, the outer heating tube 12 and the inner heating tube 13... Simultaneously, the cable protection pipe is heated. The inner heating pipe 13 heats from inside the pipe, and the outer heating pipe 12 heats from outside the pipe, so that the pipe is heated evenly. After heating is completed, the drive cylinder 11 drives the heating component 5 to retract, thereby detaching it from the cable protection pipe. Then, the drive motor 9 reverses to move the heating component 5 away from the flaring component 6 and the cable protection pipe, and then returns it to its initial position. Then, the flaring component 6 is activated to flare the heated part of the cable protection pipe. After the flaring of the cable protection pipe is completed, the flaring component 6 is separated from the cable protection pipe. Then, the pressing component 7 is used to release the cable protection pipe from its fixation. Finally, the cable protection pipe can be removed from the support component 8.
[0022] Furthermore, the drive motor 9 on the drive assembly 4 is fixedly mounted on the lower end of the support base plate 3, and the Z-shaped connecting plate 17 on the heating assembly 5 is fixedly mounted on the piston rod of the drive cylinder 11. The outer heating tube 12 and the inner heating tube 13 on the heating assembly 5 are coaxial. Four first arc-shaped connecting plates 14 and four second arc-shaped connecting plates 15 are provided on the heating assembly 5. The four first arc-shaped connecting plates 14 are symmetrically fixedly mounted on one end of the outer heating tube 12, and the four second arc-shaped connecting plates 15 are symmetrically fixedly mounted on one end of the inner heating tube 13. Both the outer heating tube 12 and the inner heating tube 13 use resistance wire heating. They are connected to different outputs of an external power supply via high-temperature resistant wires to achieve independent power supply, allowing for separate control of the heating temperature according to actual processing requirements. The inner diameter of the outer heating tube 12 needs to be slightly larger than the outer diameter of the MPP cable protection tube to be processed to ensure close contact with the outer wall of the pipe for effective heating; the outer diameter of the inner heating tube 13 needs to be slightly smaller than the inner diameter of the MPP cable protection tube to be processed to ensure smooth insertion into the pipe and maintain a suitable distance from the inner wall of the pipe for uniform heating. Both the first arc-shaped connecting plate 14 and the second arc-shaped connecting plate 15 are made of heat-resistant metal.
[0023] Finally, by setting up a heating assembly 5 consisting of an outer heating pipe 12, an inner heating pipe 13, a first arc-shaped connecting plate 14, a second arc-shaped connecting plate 15, a connecting base ring 16, and a Z-shaped connecting plate 17, the inner heating pipe 13 is located inside the outer heating pipe 12. When heating the MPP cable protection pipe, the inner heating pipe 13 heats from inside the pipe, and the outer heating pipe 12 heats from outside the pipe, so that the inner and outer walls of the pipe are heated at the same time, effectively solving the problem of uneven heating of the pipe caused by the traditional single external heating method. After the pipeline is heated evenly, the softening degree of each part is consistent during the subsequent expansion processing, avoiding local over-softening or under-softening caused by uneven heating. This ensures the processing quality of the socket joint, improves the sealing performance of the joint, and enhances the overall strength and stability of the pipeline connection, reducing potential threats to the safety and reliability of the cable laying project. By setting up the drive assembly 4 and installing the heating assembly 5 on the drive assembly 4, the drive motor 9 drives the rotating connecting plate 10 to rotate. The drive cylinder 11 can control the extension and retraction of the heating assembly 5, thereby realizing the automatic movement of the heating assembly 5 in the horizontal and vertical directions. This not only improves the efficiency of the connection between the heating assembly 5 and the cable protection pipe during processing and reduces the time and effort spent on manual operation, but also allows for more precise control of the position of the heating assembly 5. This enables the heating assembly 5 to accurately heat the parts of the MPP cable protection pipe that need to be processed, further ensuring the uniformity and stability of heating, and providing strong support for improving the processing quality of the socket joint.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
