Description

Technical Field

[0001] This utility model belongs to the field of tire copper parts manufacturing technology, and in particular relates to an MPP power pipe hot melt butt welding device. Background Technology

[0002] MPP pipe, also known as MPP power cable protection pipe, is divided into open-cut and trenchless types. MPP trenchless pipe is also called MPP jacking pipe or pull pipe. MPP pipe uses modified polypropylene as the main raw material and has the characteristics of high temperature resistance and external pressure resistance. It is suitable for high voltage transmission cable ducts below 10KV. In power construction, power pipes need to be connected together and buried in the soil. Therefore, a hot-melt butt welding device is used. When MPP power pipes are hot-melt butt welded, the surfaces of the pipes to be joined need to be cut to ensure the flatness of the joint.

[0003] When cutting existing MPP power pipes, dirt, dust, and other impurities may remain on the pipe surface. If not cleaned in time, these impurities will become trapped between the two molten pipe surfaces. After cooling, these impurities will cause uneven structure at the pipe connection, creating stress concentration points. These stress concentration points may lead to cracks at the connection, thereby reducing welding quality and even causing pipe connection failure and leakage. To address these issues, a thermal fusion butt welding device for MPP power pipes is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an MPP power pipe heat fusion butt welding device, which can clean dirt, dust and other impurities from the surface of the power pipe after cutting, thereby avoiding pipe connection failure and leakage, and solving the above-mentioned technical problems.

[0023] In the following description, embodiments of the MPP power pipe hot-melt butt welding device of the present invention will be described with reference to the accompanying drawings.

[0024] Example 1:

[0025] Figure 1-5This invention illustrates an embodiment of an MPP power pipe heat fusion welding device, comprising a base 1.

The slide 4 is located on the top of the support base 2. The guide block 12 is slidably connected to the guide groove 13, and the guide block 12 and guide groove 13 are adapted to each other. This slidable connection and adaptation of the guide block 12 and guide groove 13 ensures the slide 4 remains stable when moving through the support base 2, preventing it from shifting during movement. A diagonal brace 5 is fixedly connected to one side of the slide 4. The inner cavity of the slide 4 is rotatably connected to the connecting frame 6. A spring 7 is fixedly fitted on the outer side of the connecting frame 6.

A cleaning plate 10 is fixedly connected to the output end of the drive motor 9. A protective shell 11 is fitted on the outer side of the cleaning plate 10 and is fixedly connected to the connecting frame 6. By placing the pipe inside the fixing mechanism 3 and then fixing it through the fixing mechanism 3, the pipe is cut by an external cutting device. Then, the handle 8 is pulled, and the handle 8 drives the slide 4 to move through the support seat 2. The handle 8 drives the spring 7 to compress and rotate through the connecting frame 6, and at the same time, the connecting frame 6 rotates through the slide 4. Then, the drive motor 9 is started, and the drive motor 9 drives the cleaning plate 10 to rotate. The cleaning plate 10 cleans the surface of the cut pipe. Then, the surface of the pipe is heated by a heating plate. After heating, the pipe is connected through the fixing mechanism 3. This achieves the purpose of cleaning dirt, dust and other impurities from the surface of the power pipe after cutting, thereby avoiding pipe connection failure and leakage.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates an embodiment of an MPP power pipe heat fusion welding device, comprising a base 1, a sliding rod fixedly connected to the upper part of the inner cavity of the base 1, and a support rod fixedly connected to the bottom corresponding to the sliding rod. A support seat 2 is fixedly connected to one side of the base 1. Fixing mechanisms 3 are evenly arranged from left to right on the top of the base 1. The fixing mechanism 3 includes a movable seat 31 slidably connected to the outside of the sliding rod, a first gripper 32 fixedly connected to the top of the movable seat 31, a connecting shaft 33 rotatably connected to the inner cavity of the first gripper 32, and a second gripper 34 rotatably connected to one side of the connecting shaft 33.

The inner cavity of the slide 4 is rotatably connected to a connecting frame 6. A spring 7 is fixedly fitted on the outer side of the connecting frame 6. A handle 8 is fixedly connected to one side of the connecting frame 6. A drive motor 9 is fixedly connected to one side of the connecting frame 6. A cleaning plate 10 is fixedly connected to the output end of the drive motor 9. A protective shell 11 is fitted on the outer side of the cleaning plate 10. The protective shell 11 is used to protect the cleaning plate 10 and prevent accidents when the cleaning plate 10 rotates. The protective shell 11 is fixedly connected to the connecting frame 6.

[0028] Working principle: In use, the user places the pipe on the surface of the first clamp 32. The second clamp 34 then rotates via the connecting shaft 33 to engage with the first clamp 32. Next, by rotating the lever 35, the lever 35 crosses the first and second clamps 32 simultaneously. Then, the fixing sleeve 36 rotates to engage with the second clamp 34, thus securing the pipe to the first clamp 32. An external cutting device then cuts the pipe surface. Finally, pulling the handle 8 moves the slide 4, which in turn moves the bottom guide block 12 and guide groove 1. 3. Slide the slide, causing the slide block 4 to move via the support base 2. Then, the handle 8 drives the spring 7 to compress and rotate via the connecting frame 6, causing the connecting frame 6 to rotate via the slide block 4. Then, start the drive motor 9, which drives the cleaning plate 10 to rotate. The cleaning plate 10 cleans the dirt, dust and other impurities on the surface of the cut pipe. Then, the heating plate heats the surface of the pipe. After heating, by adjusting the moving base 31, the pipe is heat-fused together. This achieves the purpose of cleaning the dirt, dust and other impurities on the surface of the power pipe after cutting, thereby avoiding pipe connection failure and leakage.
