Description

Technical Field

[0001] The present invention relates to the technical field of cable protection tube processing, and more particularly to a hot dip treatment device for power cable protection tubes. Background Art

[0002] Power cable protection tubes are important devices used to protect cables from external environmental and mechanical damage, and are commonly used in power transmission, communications, and other fields. Before use, power cable protection tubes are usually subjected to a hot dip treatment to enhance their corrosion resistance and weather resistance, thereby extending their service life.

[0003] As for the hot dip treatment devices currently on the market, traditional hot dip treatment devices usually immerse the cable protection tube directly into the hot dip tank for treatment. This method is simple and direct, but it also has some disadvantages and limitations. Due to direct immersion in the hot dip tank, the coating is difficult to be evenly distributed on the surface of the cable protection tube. Some areas are insufficiently coated, while other areas are too thickly coated. This makes it difficult to accurately achieve uniform coating quality, affecting the quality and consistency of the hot dip treatment, and thus affecting the quality and performance of the cable protection tube.

[0004] To this end, we propose a power cable protection tube hot dip treatment device to solve the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a hot dip treatment device for a power cable protection tube, which drives the bottom rotating shaft and the middle and lower plates to rotate and swing through the synergistic effect of the driving electric cylinder 1 and the coupling. The design of the limiting arc slide limits the sliding range of the middle and lower plates and the middle and upper plates, ensuring that the middle and lower plates and the middle and upper plates slide relatively stably during the swinging process, realizing precise swing control of the cable protection tube, ensuring uniform coverage of the coating, and improving the quality and consistency of the hot dip treatment, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a power cable protection tube hot dip treatment device, comprising

Through the structural design of the fixed plate, the support frame and the linkage plate, the linkage auxiliary mechanism can provide additional support and stability, so that the hot-dip swing mechanism is not easy to shake and become unstable during the swinging process, ensuring that the hot-dip liquid fully contacts the surface of the cable protection tube. The combination of the support plate and the driving electric cylinder in the linkage auxiliary mechanism can adjust the position of the moving plate, thereby controlling the swing amplitude of the swing rod. The two sides of the bottom of the middle and upper plate are fixedly connected to the middle plate by connecting plates. A through groove is provided in the middle of the middle plate. The outer wall of the top rotating shaft passes through the inside of the through groove of the middle plate.

By controlling the movement of the lifting cylinder, the hot dip fixing mechanism can be moved up or down, thereby realizing the lifting and lowering operation of the cable protection tube.

[0031] Example 2

[0032] See also Figure 3-4 , which is different from Example 1:

[0033] like Figure 3 、 4 As shown, the hot soak swing mechanism 20 is provided with a linkage auxiliary mechanism 30, which includes a fixed plate 31, two support frames 32, a linkage plate 33, two support plates 38 and a plurality of swing rods 311;

[0034] The top bolts of the two support frames 32 are connected to the top sides of the fixed plate 31. The top center of the fixed plate 31 passes through and is rotatably connected to a top rotating shaft 215 through a bearing. The bottom end of the top rotating shaft 215 is fixedly connected to the top of the linkage plate 33. Both sides of the linkage plate 33 are rotatably connected to a linkage rod 34. The bottom sides of the two support frames 32 are screwed to guide rails 35. The outer wall of the guide rail 35 is slidably connected to a slider 36.

[0035] Example 3

[0036] See also Figure 1 , which is different from Examples 1 and 2:

[0037] like Figure 1 As shown, a support mechanism 10 is provided outside the hot-dip swing mechanism 20 , and the support mechanism 10 includes a door-shaped bracket 11 , a top plate 12 and a lifting cylinder 13 ;

[0038] The four sides of the top plate 12 are fixedly connected to the top of the door-shaped bracket 11, the pneumatic shaft of the lifting cylinder 13 passes through the top of the top plate 12, and a fixed shell is installed on the top of the top support plate 21. The bottom end of the pneumatic shaft of the lifting cylinder 13 is fixedly connected to the top of the fixed shell of the top support plate 21. The stability of the entire device is supported by the support mechanism 10. The lifting cylinder 13 is started through the control box 101, so that the entire device including the hot dip swing mechanism 20, the linkage auxiliary mechanism 30 and the hot dip fixing mechanism 40 drives the cable protection tube to descend into the hot dip tank.

[0039] like Figure 1 As shown, a control box 101 is installed on one side of the door-shaped bracket 11, and the electrical signal end of the control box 101 is electrically connected to the electrical signal ends of the angle sensor 214, the lifting cylinder 13, the driving electric cylinder 1 27 and the driving electric cylinder 2 37 respectively;

[0040] The control box 101 can obtain the angle information of the middle and lower plates 24 and the working status of the driving electric cylinder 1 27 in real time by connecting with the electrical signal of the angle sensor 214 and the driving electric cylinder 1 27. According to the feedback signal of the angle sensor 214, the control box 101 can accurately control the extension and contraction of the driving electric cylinder 1 27, thereby driving the rotation of the coupling 28 and the bottom rotating shaft 29, realizing precise swinging and control of the cable protection tube, and ensuring uniform coverage of the coating. The control box 101 can control the extension and contraction of the driving electric cylinder 2 37 in real time by connecting with the electrical signal of the driving electric cylinder 2 37, thereby adjusting the movement state of the linkage auxiliary mechanism 30. The control box 101 can realize the rising and falling of the pneumatic shaft of the lifting cylinder 13 by connecting with the electrical signal of the lifting cylinder 13. By controlling the movement of the lifting cylinder 13, the hot dip fixing mechanism 40 can be moved up or down, thereby realizing the lifting and lowering operation of the cable protection tube.

[0041] The working principle of the present invention is as follows: the device adjusts the distance between the two pneumatic tube clamps 42 through the bidirectional synchronous drive module 41 to adapt to cable protection tubes of different lengths, and then uses the pneumatic tube clamp 42 to clamp and fix the end of the cable protection tube, and then starts the lifting cylinder 13 through the control box 101, so that the entire device including the hot dip swing mechanism 20, the linkage auxiliary mechanism 30 and the hot dip fixing mechanism 40 drives the cable protection tube to descend into the hot dip tank. When the hot dip process is completed, the angle sensor 214 is started by the control box 101 to detect the angle of the middle and lower layer plates 24, and transmits the electrical signal to the control box 101, and then the control box 101 is used to detect the angle of the middle and lower layer plates 24. The control box 101 controls the driving electric cylinder 1 27 to start, so that its electric shaft retracts and drives the coupling 28, which drives the bottom rotating shaft 29 to rotate through the coupling 28. The detection of the angle sensor 214 controls the middle and lower layer plates 24 to slide on the corresponding limit arc slide plate 212, and drives the top middle and upper layer plates 211 to keep rotating at the same time through the four fixed columns 22, and slides on the limit arc slide plate 212 at the bottom of the top support plate 21 through the middle and upper layer plates 211 to maintain sufficient rotation stability. At the same time, the sliding rods 26 on both sides of the bottom are driven to rotate inside the arc groove 25 through the middle and lower layer plates 24, and the bottom ends thereof drive the two-way synchronous driving connected thereto. The module 41 swings, and finally drives the cable protection tube clamped and fixed on the pneumatic tube clamp 42 to swing in the hot dip tank and fully contact the hot dip liquid. Since the top of the top rotating shaft 215 passes through the bottom of the middle and upper plate 211, the top rotating shaft 215 rotates synchronously with it, and then drives the linkage plate 33 of the linkage auxiliary mechanism 30 to rotate synchronously, so that the linkage plate 33 reciprocates and pushes the two linkage rods 34 to move to both sides, so that the two linkage rods 34 push the support plate 38 to drive the slider 36 to slide on the guide rail 35, and the movable plate 39 and the multiple swing rods 311 are driven to reciprocate synchronously by the support plate 38 and the fixed lower part of the driving electric cylinder 2 37 to drive the surrounding heat. The immersion liquid is stirred, and at the same time, the start of the second driving electric cylinder 37 can be controlled to make its electric shaft push the movable plate 39 to move downward, and then the movable plate 39 drives multiple swing rods 311 to be driven synchronously, and the deep contact or surface contact between the cable protection tube and the hot-immersion liquid is adjusted to meet different coating requirements, thereby assisting in stirring the hot-immersion liquid, maintaining the uniformity of the liquid, and making the coating of the cable protection tube uniform and sufficient. Finally, the control box 101 stops each driving device, and then controls the lifting cylinder 13 to drive the hot-immersion fixing mechanism 40 to move upward, and makes the pneumatic tube clamp 42 separate from the cable protection tube, so that it is transported to the drying area along the roller shaft.
