Description
Technical Field
[0001] This utility model relates to the field of ultra-high voltage cable technology, specifically a device for forming smooth aluminum ultra-high voltage cables. Background Technology
[0002] Ultra-high voltage (UHV) cables are electrical equipment specifically designed for transmitting high-voltage electrical energy. UHV cables refer to cables with a rated voltage greater than 110 kV. Common UHV cables have rated voltages of 220 kV, 330 kV, 500 kV, or even higher. These cables are mainly used for transmitting power, communication, and control signals. Based on their structure and application, they can be further classified, such as single-core cables, three-core cables, aluminum-core cables, and copper-core cables.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: In the production of ultra-high voltage cables, it is generally necessary to wrap insulating material around the surface of the cable to achieve insulation protection, enhance mechanical strength, or realize other specific functions. Since some wrapping machines lack a cable guiding mechanism, when wrapping large-sized cables, the suspended cables are prone to sinking and dragging on the ground. Therefore, in order to address the above problems, an apparatus for forming smooth aluminum ultra-high voltage cables is proposed. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The device for forming smooth aluminum ultra-high voltage cables according to this utility model includes a machine body and a support device. A fixing device is rotatably connected to the side wall of the machine body, and a guide hole is opened on the surface of the machine body. A support device is provided on one side of the machine body. The support device includes a pad plate. The pad plate is located on one side of the machine body. Two movable frames are slidably connected to the inner wall of the pad plate. A support frame is slidably connected to the inner wall of each of the two movable frames. A sleeve is fixedly connected to the inner surface of the support frame. The support frame drives the sleeve to move. After the two sleeves are put together, the cable is inserted into the inner wall of the two sleeves. By setting the pad plate, movable frames, support frames and sleeves, the cable can be supported and guided at the same time.
[0006] Preferably, the inner surface of the sleeve is rotatably connected to multiple guide wheels, which rotate on the inner surface of the sleeve. By setting the guide wheels, wear between the cable and the sleeve can be reduced.
[0007] Preferably, the inner surface of the pad is rotatably connected to a main threaded rod, the surface of the main threaded rod is threadedly connected to the inner walls of the two movable frames, and the surface of the main threaded rod is provided with two opposite thread lines. When it is necessary to adjust the position of the movable frame, the main threaded rod is rotated to rotate on the inner walls of the two movable frames, and the movable frame is driven to slide on the inner surface of the pad.

[0008] Preferably, the surface of the movable frame is rotatably connected to two auxiliary threaded rods, and a movable block is fixedly connected to the side wall of the support frame near the auxiliary threaded rods. The inner wall of the movable block is threadedly connected to the surface of the auxiliary threaded rods. When it is necessary to adjust the height of the support frame, the auxiliary threaded rods are rotated to rotate on the surface of the movable frame and the inner wall of the movable block. The movable block will drive the support frame to move in height. By setting the auxiliary threaded rods and the movable block, the height of the support frame can be easily adjusted.
[0009] Preferably, the surfaces of the two auxiliary threaded rods are engaged with a belt. When using the two auxiliary threaded rods, pulling the belt causes the belt to drive the two auxiliary threaded rods to rotate. By setting the belt, the two auxiliary threaded rods can be driven to rotate simultaneously.
[0010] Preferably, both sides of the pad are provided with limiting devices. The limiting device includes a placement block. The side wall of the placement block is fixedly connected to the side wall of the pad. A rotating rod is rotatably connected to the surface of the placement block. A positioning pin is threadedly connected to the inner wall of the machine body. By rotating the positioning pin to the rotating rod and the inner wall of the machine body, the position of the pad can be limited by setting the placement block, the rotating rod and the positioning pin.
[0011] Preferably, the surface of the rotating rod is provided with a storage groove, and part of the structure of the body is inserted into the inner wall of the storage groove of the rotating rod. Multiple reinforcing blocks are fixedly connected to the inner surface of the rotating rod.

Then the main threaded rod is rotated to make the main threaded rod rotate on the inner surface of the pad and the inner wall of the two moving frames. The moving block will drive the support frame and the sleeve to move. The two sleeves are fitted on the surface of the cable, and the guide wheel will press against the surface of the cable. When the cable moves, it will drive the guide wheel to rotate on the inner surface of the sleeve. By setting the entire device, the cable can be supported and the cable dragging on the ground can be reduced. The main threaded rod and the auxiliary threaded rod can adjust the position of the support frame to adapt to different specifications of sleeves, thus adapting to different specifications of cables.
[0014] 2. In this utility model, after the pad is placed in the appropriate position, the rotating rod is pushed to rotate on the surface of the placement block.

[0023] Please see Figure 1-5 As shown, a device for forming smooth aluminum ultra-high voltage cables includes a body 1 and a support device 4. A fixture 2 is rotatably connected to the side wall of the body 1, and a guide hole 3 is opened on the surface of the body 1. The support device 4 is provided on one side of the body 1. The support device 4 includes a pad 41, which is located on one side of the body 1. Two movable frames 42 are slidably connected to the inner wall of the pad 41. A support frame 43 is slidably connected to the inner wall of each of the two movable frames 42. A sleeve 44 is fixedly connected to the inner surface of the support frame 43. During operation, the pad 41 is placed in a suitable position, and the sleeve 44 is inserted into the inner surface of the support frame 43 and fixed. Then, the movable frames 42 are pushed to move the support frame 43, and the support frame 43 moves the sleeve 44. After the two sleeves 44 are put together, the cable is inserted into the inner wall of the two sleeves 44. By setting the pad 41, movable frames 42, support frames 43 and sleeves 44, the cable can be supported and guided at the same time.
[0024] Multiple guide wheels 45 are rotatably connected to the inner surface of the sleeve 44. During operation, the cable moves on the surface of the guide wheels 45, and the guide wheels 45 rotate on the inner surface of the sleeve 44. By setting the guide wheels 45, the wear between the cable and the sleeve 44 can be reduced.
[0025] The inner surface of the pad 41 is rotatably connected to a main thread rod 46. The surface of the main thread rod 46 is threadedly connected to the inner wall of the two movable frames 42. The surface of the main thread rod 46 is provided with two opposite thread lines. During operation, rotating the main thread rod 46 causes it to rotate on the inner wall of the two movable frames 42, and the movable frames 42 are driven to slide on the inner surface of the pad 41. The position of the movable frames 42 can be easily adjusted by setting the main thread rod 46.
[0026] Two auxiliary threaded rods 47 are rotatably connected to the surface of the movable frame 42. A movable block 48 is fixedly connected to the side wall of the support frame 43 near the auxiliary threaded rods 47. The inner wall of the movable block 48 is threadedly connected to the surface of the auxiliary threaded rods 47. During operation, rotating the auxiliary threaded rods 47 causes them to rotate on the surface of the movable frame 42 and the inner wall of the movable block 48. The movable block 48 will then drive the support frame 43 to move in height. By setting the auxiliary threaded rods 47 and the movable block 48, the height of the support frame 43 can be easily adjusted.
[0027] The surfaces of the two auxiliary threaded rods 47 are engaged with a belt 49; during operation, pulling the belt 49 causes the two auxiliary threaded rods 47 to rotate, and by setting the belt 49, the two auxiliary threaded rods 47 can be driven to rotate simultaneously.
[0028] Both sides of the pad 41 are provided with limiting devices 5. The limiting device 5 includes a placement block 51. The side wall of the placement block 51 is fixedly connected to the side wall of the pad 41. A rotating rod 52 is rotatably connected to the surface of the placement block 51. The rotating rod 52 is threadedly connected to the inner wall of the machine body 1 with a positioning pin 53. During operation, the rotating rod 52 is pushed to rotate on the surface of the placement block 51. After the rotating rod 52 is sleeved on the surface of part of the structure of the machine body 1, the positioning pin 53 is rotated to the rotating rod 52 and the inner wall of the machine body 1. By setting the placement block 51, the rotating rod 52 and the positioning pin 53, the position of the pad 41 can be limited.
[0029] The rotating rod 52 has a storage groove 55 on its surface. Part of the structure of the body 1 is inserted into the inner wall of the storage groove 55 of the rotating rod 52. Multiple reinforcing blocks 54 are fixedly connected to the inner surface of the rotating rod 52. When working, the rotating rod 52 will be sleeved on the surface of the body 1 through the storage groove 55. At the same time, when the rotating rod 52 is subjected to force, it will also transmit part of the force to the reinforcing blocks 54. By setting the reinforcing blocks 54, the strength of the rotating rod 52 can be increased.
[0030] Working principle: When it is necessary to wrap the cable, after placing the pad 41 on the side wall of the machine body 1, pull the belt 49 to make the two auxiliary threaded rods 47 rotate simultaneously. The auxiliary threaded rods 47 rotate on the surface of the moving frame 42 and the inner wall of the moving block 48. The moving block 48 will drive the support frame 43 to move. After the support frame 43 moves to a suitable height, the sleeve 44 is fixed on the inner surface of the support frame 43. Then, the cable is laid in a suitable position. Then, rotate the main threaded rod 46 to make the main threaded rod 46 rotate on the inner surface of the pad 41 and the inner wall of the two moving frames 42. The moving block 48 will drive the support frame 43 and the sleeve 44 to move. The two sleeves 44 are fitted on the surface of the cable, and the guide rollers 45 will press against the surface of the cable. When the cable moves, it will drive the guide rollers 45 to move. 5. Rotating on the inner surface of the sleeve 44, the entire device can support the cable and reduce cable dragging. The main thread rod 46 and the auxiliary thread rod 47 can adjust the position of the support frame 43 to adapt to different specifications of sleeves 44, thus adapting to different specifications of cables. After the pad 41 is placed in the appropriate position, push the rotating rod 52 to rotate on the surface of the placement block 51. The rotating rod 52 is fitted onto part of the structural surface of the body 1 through the storage groove 55. Then, the positioning pin 53 is rotated to the rotating rod 52 and the inner wall of the body 1. When the rotating rod 52 is under force, it will transmit the force to the reinforcing block 54. By setting the entire device, the position of the pad 41 can be restricted, reducing the possibility of the pad 41 moving randomly.
