Description

Technical Field

[0001] This utility model belongs to the field of cable pipe processing technology, specifically an MPP cable pipe interface welding device. Background Technology

[0002] MPP cable conduit (modified polypropylene cable protection pipe) is a type of power cable protection pipe made primarily of modified polypropylene through an extrusion molding process. It features lightweight, high strength, corrosion resistance, and excellent insulation properties, making it widely used in power engineering to protect high-voltage cables from external mechanical damage and environmental corrosion, while also facilitating cable laying and maintenance. It offers various connection methods, including heat fusion and electrofusion, ensuring convenient construction and a long service life.

[0003] In existing technologies, traditional hot melt welding typically uses fixed heating plates or hot melt welding machines, which result in uneven heat distribution. This can easily lead to overheating in some areas of the pipe joint while underheating in others. Localized overheating may cause pipe deformation, while underheating may result in incomplete melting at the joint.

[0004] Therefore, this utility model provides an MPP cable pipe interface welding device. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problems of uneven heat distribution in traditional hot-melt welding, which typically uses fixed heating plates or hot-melt welding machines, leading to overheating in some areas of the pipe joint and underheating in others, localized overheating may cause pipe deformation, while underheating may result in insufficient melting at the joint.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An MPP cable conduit interface welding device of this utility model includes a base plate, and a welding mechanism is provided on the top of the base plate. The welding mechanism includes:

[0007] A hot-melt assembly includes a pair of first square plates fixed to the top of a base plate by a set of fixing rods. The pair of square plates are rotatably connected to a rotating tube through a pair of first rotating holes. An electric heater is provided on the inner wall of the rotating tube, and an electric heating element is connected to the electric heater. A scraper is fixed to the inner wall of the rotating tube. A rotating assembly for driving the rotating tube to rotate is provided on the base plate.

[0008] Fastening components are mounted on the base plate to assist in cable conduit connection.

[0009] Preferably, the rotating assembly includes a gear ring fixed to the outer circular wall of the rotating tube, a first motor fixed to the top of the base plate, a first drive rod at the output end of the first motor, a first gear fixed to the end of the first drive rod away from the first motor, and the first gear meshing with the gear ring.

[0010] Preferably, the fastening assembly includes an adjustment unit and a set of first sliding grooves on the base plate. A sliding block is slidably connected in the first sliding groove, and a second square plate is fixedly connected to the top of a pair of sliding blocks. A set of second sliding grooves is provided on the second square plate.

[0011] Preferably, a circular block is slidably connected in the second sliding groove, and a clamping block is fixedly connected to one end of the circular block through a fixing block. A rotating groove is opened on the side wall of the second square plate away from the clamping block. A rotating ring is rotatably connected in the rotating groove. A toothed disc is fixedly connected to the rotating ring. A set of inclined grooves is opened on the toothed disc. The end of the circular block away from the clamping block is slidably connected in the inclined groove.

[0012] Preferably, a second motor is fixedly connected to the side wall of the second square plate, and a second drive rod is provided at the output end of the second motor. A second gear is fixedly connected to the end of the second drive rod away from the second motor, and the second gear meshes with the gear plate.

[0013] Preferably, the adjustment unit includes a first rotating rod rotatably connected to the top of the second square plate via a first rotating shaft, a concave frame fixed to the top of the base plate, an adjustment rod rotatably connected to the top of the concave frame via a second rotating hole, an adjustment valve fixed to the top of the adjustment rod, a second rotating rod fixed to the bottom of the adjustment rod, and the two ends of the second rotating rod being rotatably connected to the first rotating rod via a pair of second rotating shafts.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The MPP cable pipe joint welding device of this utility model uses an electric heating element to heat melt the joint of two cable pipe sections, softening and connecting them. Then, a fastening component assists in the connection, and a scraper removes deformed protrusions to complete the welding operation. This solves the problems in the prior art, where traditional hot melt welding usually uses a fixed heating plate or hot melt welding machine, which has uneven heat distribution. This can easily lead to overheating in some areas of the pipe joint and insufficient heating in others. Local overheating may cause pipe deformation, while insufficient heating may lead to incomplete melting at the joint.

[0016] 2. The MPP cable pipe interface welding device of this utility model uses a second motor to drive a second drive rod to rotate, which in turn drives a second gear to rotate. The second gear drives a meshing gear disc to rotate, thereby pressing a circular block through an inclined groove. This allows the circular block to slide within a second sliding groove, enabling the fixed clamping block to position and clamp the cable pipe, keeping the ends of the cable pipe aligned and preventing inaccurate positioning that could lead to deviations in heat fusion and affect the welding effect.

Detailed Implementation

[0023] 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.

[0024] like Figures 1 to 4As shown, an MPP cable conduit interface welding device according to an embodiment of the present invention includes a base plate 1, a welding mechanism on the top of the base plate 1, the welding mechanism including: a hot melt assembly, the hot melt assembly including a pair of first square plates 2 fixed to the top of the base plate 1 by a set of fixing rods, the pair of square plates being rotatably connected to a rotating tube 3 through a pair of first rotating holes, an electric heater 4 being provided on the inner wall of the rotating tube 3, the electric heater 4 being connected to an electric heating element 28, a scraper 5 being fixed to the inner wall of the rotating tube 3, and a rotating assembly for driving the rotating tube 3 to rotate on the base plate 1; and a fastening assembly, provided on the base plate 1 for assisting in cable conduit docking.

[0025] During operation, the heating element 28 is used to heat melt the weld joint of the two cable pipe sections, softening the connection. Then, the fastening component assists in the connection, and the scraper 5 removes any deformed protrusions, completing the welding operation. This solves the problem in existing technologies where traditional hot melt welding usually uses a fixed heating plate or hot melt welding machine, resulting in uneven heat distribution. This can easily lead to overheating in some areas of the pipe joint while underheating in others. Local overheating may cause pipe deformation, while underheating may lead to insufficient melting at the joint.

[0026] The rotating assembly includes a gear ring 6 fixed to the outer circular wall of the rotating tube 3, a first motor 7 fixed to the top of the base plate 1, a first drive rod 8 provided at the output end of the first motor 7, a first gear 9 fixed to the end of the first drive rod 8 away from the first motor 7, and the first gear 9 meshing with the gear ring 6.

[0027] During operation, the first motor 7 drives the first drive rod 8 to rotate, which in turn drives the first gear 9 to rotate. The first gear 9 then drives the meshing gear ring 6 to rotate, allowing the heating element 28 to heat melt around the welded joint of the two cable pipes, thus softening the connection. The scraper 5 can also scrape off any protrusions that occur when fastening components are joined, preventing them from affecting the heat melting effect.

[0028] The fastening assembly includes an adjustment unit and a set of first sliding grooves 10 opened on the base plate 1. Sliding blocks 11 are slidably connected in the first sliding grooves 10. A second square plate 12 is fixedly connected to the top of a pair of sliding blocks 11. A set of second sliding grooves 13 are opened on the second square plate 12.

[0029] A circular block 14 is slidably connected in the second sliding groove 13. One end of the circular block 14 is fixedly connected to a clamping block 15 via a fixing block. A rotating groove 16 is provided on the side wall of the second square plate 12 away from the clamping block 15. A rotating ring 17 is rotatably connected in the rotating groove 16. A gear 18 is fixedly connected to the rotating ring 17. A set of inclined grooves 19 are provided on the gear 18. The end of the circular block 14 away from the clamping block 15 is slidably connected in the inclined groove 19.

[0030] A second motor 20 is fixedly connected to the side wall of the second square plate 12. The output end of the second motor 20 is provided with a second drive rod 21. A second gear 22 is fixedly connected to the end of the second drive rod 21 away from the second motor 20. The second gear 22 meshes with the gear plate 18.

[0031] During operation, the second motor 20 drives the second drive rod 21 to rotate, which in turn drives the second gear 22 to rotate. The second gear 22 then drives the meshing gear disc 18 to rotate, which in turn compresses the circular block 14 through the inclined groove 19. This allows the circular block 14 to slide within the second sliding groove 13, enabling the fixed clamping block 15 to position and clamp the cable pipe, ensuring that the ends of the cable pipes are aligned. This prevents inaccurate positioning, which could lead to deviations in the heat fusion process and affect the welding effect. The first motor 7 and the second motor 20 are stepper motors.

[0032] The adjustment unit includes a first rotating rod 23 rotatably connected to the top of the second square plate 12 via a first rotating shaft, a concave frame 24 fixed to the top of the base plate 1, an adjustment rod 25 rotatably connected to the top of the concave frame 24 via a second rotating hole, an adjustment valve 26 fixed to the top of the adjustment rod 25, a second rotating rod 27 fixed to the bottom of the adjustment rod 25, and the two ends of the second rotating rod 27 being rotatably connected to the first rotating rod 23 via a pair of second rotating shafts.

[0033] During operation, rotating the regulating valve 26 causes the regulating rod 25 to drive the second rotating rod 27 to rotate, which in turn causes a pair of first rotating rods 23 to pull a pair of second square plates 12 to move. This allows the connection stability to be improved by pulling and squeezing the ends of the two cable pipes during heat fusion.

[0034] Working principle: The electric heating element 28 is used to heat melt the weld joint of the two cable pipes, softening the connection. Then, the fastening component assists in the connection, and the scraper 5 removes deformed protrusions to complete the welding operation. This solves the problem in the existing technology where traditional hot melt welding usually uses a fixed heating plate or hot melt welding machine, which has uneven heat distribution. This can easily lead to overheating in some areas of the pipe joint and underheating in others. Local overheating may cause pipe deformation, while underheating may cause insufficient melting at the joint.

[0035] The first motor 7 drives the first drive rod 8 to rotate, which in turn drives the first gear 9 to rotate. The first gear 9 drives the meshing gear ring 6 to rotate, so that the heating element 28 can heat melt around the weld joint of the two cable pipes, softening the connection. The scraper 5 can scrape off any protrusions that occur when fastening components are joined, so as to avoid affecting the heat melting effect.

[0036] The second motor 20 drives the second drive rod 21 to rotate, which in turn drives the second gear 22 to rotate. The second gear 22 then drives the meshing gear disc 18 to rotate, thereby pressing the circular block 14 through the inclined groove 19. This allows the circular block 14 to slide within the second sliding groove 13, enabling the fixed clamping block 15 to position and clamp the cable pipe, keeping the ends of the cable pipe aligned and preventing inaccurate positioning that could lead to deviations in the heat fusion process and affect the welding effect. The first motor 7 and the second motor 20 are stepper motors.

[0037] Rotating the regulating valve 26 allows the regulating rod 25 to drive the second rotating rod 27 to rotate, thereby pulling a pair of second square plates 12 to move through a pair of first rotating rods 23. This allows the connection stability to be improved by pulling and squeezing the ends of the two cable pipes during heat fusion.
