DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] For the embodiments, please refer to Figure 1-2 , the present invention provides a technical solution: a cable straightening device for municipal engineering, including a main body 10 and a stretching component 20. The stretching component 20 is slidably installed on the front surface of the main body 10. The stretching component 20 includes a frame 21, stretching rollers 22 and a second magnetic plate 23. The frame 21 is slidably installed on the front surface of the main body 10. The stretching rollers 22 are evenly rotatably installed inside the frame 21. The second magnetic plate 23 is fixedly installed at the bottom of the frame 21. An electric hydraulic push rod 16 is fixedly installed directly below the frame 21 at the bottom of the main body 10. A support plate 17 is fixedly installed at the top of the electric hydraulic push rod 16. A first magnetic plate 18 is fixedly installed on the support plate 17. The magnetic poles of the adjacent surfaces between the first magnetic plate 18 and the second magnetic plate 23 are the same;

[0022] Among them, the support plate 17 is supported by the electric hydraulic push rod 16. At the same time, through the repulsive action between the first magnetic plate 18 and the second magnetic plate 23, the frame 21 is located above the support plate 17, and there is a space between the frame 21 and the support plate 17. When using the stretching component 20 to stretch the cable, the cable is wound around the stretching rollers 22. The support plate 17 is pushed upward by the electric hydraulic push rod 16. Then, the support plate 17 pushes the frame 21 to move upward through the repulsive action between the first magnetic plate 18 and the second magnetic plate 23. Then, the stretching rollers 22 stretch the cable. And during the stretching process of the cable, the magnetic force between the first magnetic plate 18 and the second magnetic plate 23 can play a buffering role, avoiding rigid stretching of the cable, preventing damage to the cable, and improving the stretching quality of the cable.

[0023] Among them, a first guide roller 11 is provided at one end of the front surface of the main body 10, and a winding roller 14 is provided at the other end of the front surface of the main body 10; A driving motor 15 is fixedly installed on one side of the back surface of the main body 10 through bolts. The output end of the driving motor 15 is fixedly connected to the central axis of the winding roller 14; The first guide roller 11 and the winding roller 14 are on the same plane; A second guide roller 12 is rotatably installed on one side of the front surface of the main body 10 close to the first guide roller 11. The height dimension of the second guide roller 12 is smaller than the height dimension of the stretching roller 22; A third guide roller 13 is rotatably installed on one side of the front surface of the main body 10 close to the winding roller 14. The height dimension of the third guide roller 13 is smaller than the height dimension of the stretching roller 22;

[0024] Among them, when the cable needs to be stretched, the cable is wound around the first guide roller 11, the second guide roller 12, the stretching roller 22, and the third guide roller 13 in sequence, and the end of the cable is wound around the winding roller 14. Then, the cable is straightened by the stretching assembly 20. Next, the driving motor 15 is turned on, and then the driving motor 15 drives the winding roller 14 to rotate, and the cable is wound by the rotating winding roller 14, and the cable is straightened during the process of winding the cable.

[0025] Among them, sliding rods 24 are symmetrically and fixedly installed on the main body 10, and sliding sleeves 25 that cooperate with the sliding rods 24 are symmetrically and fixedly installed on the back surface of the frame 21. Through the cooperation of the sliding sleeves 25 and the sliding rods 24, the frame 21 can be slidably installed on the main body 10. The support plate 17 is supported by the electro-hydraulic push rod 16. At the same time, due to the repulsive force between the first magnetic plate 18 and the second magnetic plate 23, the frame 21 is located above the support plate 17, and there is a space between the frame 21 and the support plate 17. When stretching the cable, the cable will generate a downward force on the stretching assembly 20, and then the magnetic force between the first magnetic plate 18 and the second magnetic plate 23 can play a buffering role, avoiding rigid stretching of the cable and preventing damage to the cable; when the cable does not need to be stretched, the stretching assembly 20 can slide freely upward, and when the stretching assembly 20 moves downward, it is affected by the repulsive force between the first magnetic plate 18 and the second magnetic plate 23, so that there is a space between the frame 21 and the support plate 17.

[0026] Among them, limiting grooves are provided on the surface of the stretching roller 22. Through the limiting grooves, the position of the cable can be restricted, and when the cable is stretched, the cable can be prevented from falling off the stretching roller 22.

[0027] Among them, the second magnetic plate 23 is located directly above the first magnetic plate 18, and the surface size of the second magnetic plate 23 is the same as the surface size of the first magnetic plate 18. When the electro-hydraulic push rod 16 pushes the support plate 17 close to the frame 21, due to the repulsive force between the first magnetic plate 18 and the second magnetic plate 23, the frame 21 is located above the support plate 17, and there is a space between the frame 21 and the support plate 17.

[0028] Among them, both the second magnetic plate 23 and the first magnetic plate 18 are made of strong magnets. The repulsive force generated between the first magnetic plate 18 and the second magnetic plate 23 can separate the frame 21 and the support plate 17. When the cable is stretched, the cable stretches the stretching assembly 20, and the magnetic force between the first magnetic plate 18 and the second magnetic plate 23 can play a buffering role, avoiding rigid stretching of the cable and preventing damage to the cable, thus improving the stretching quality of the cable.

[0029] Working principle: When in use, when it is necessary to stretch the cable, the cable is successively wound around the first guide roller 11, the second guide roller 12, the stretching roller 22, and the third guide roller 13, and the end of the cable is wound around the winding roller 14. Then, the support plate 17 is supported by the electro-hydraulic push rod 16. At the same time, due to the repulsive force between the first magnetic plate 18 and the second magnetic plate 23, the frame 21 is located above the support plate 17, and there is a space between the frame 21 and the support plate 17. When using the stretching assembly 20 to stretch the cable, the cable is wound around the stretching roller 22. The electro-hydraulic push rod 16 pushes the support plate 17 upward. Then, the support plate 17 pushes the frame 21 to move upward through the repulsive force between the first magnetic plate 18 and the second magnetic plate 23. Then, the stretching roller 22 stretches the cable. And during the stretching process of the cable, the magnetic force between the first magnetic plate 18 and the second magnetic plate 23 can play a buffering role to avoid rigid stretching of the cable. Then, the driving motor 15 is turned on, and the driving motor 15 drives the winding roller 14 to rotate, and the cable is wound by the rotating winding roller 14, and the cable is straightened during the winding process.
