[0027] Embodiment:

[0028] Please refer to Figures 1-3 , an automatic tension adjusting device for overhead wires, including an operating table 1. A pair of first fixing plates 3 are fixedly connected to the top end of the operating table 1. A rotating roller 4 is rotatably connected between the pair of first fixing plates 3. A pair of second fixing plates 6 are fixedly connected to the top end of the operating table 1. A chute 11 communicating with the outside is provided inside each of the pair of second fixing plates 6. An adjusting component 2 is provided inside the chute 11;

[0029] The adjusting assembly 2 includes a pair of adjusting plates 21 fixedly connected to the outer ends of one of the second fixing plates 6. The pair of adjusting plates 21 are arranged in mirror symmetry. An alarm 22 is fixedly connected to the top end of the adjusting plate 21, and an alarm button 23 is fixedly connected to the bottom end of the adjusting plate 21. The alarm button 23 is electrically connected to the alarm 22.

[0030] When the overhead wire is produced in this solution, since the overhead wire is subjected to tensile force during the drawing process, the tension of the overhead wire will change, which may cause the overhead wire to break. The purpose of the automatic tension adjusting device for overhead wires during production is to automatically adjust the tension to ensure that the wire maintains a relatively stable tension during processes such as drawing and stranding, and reduce the risk of the overhead wire breaking due to changes in tension.

[0031] Please refer to Figures 2-3 , a slider 25 is slidably connected to the inside of each of the pair of chutes 11. A pressing plate 26 is fixedly connected to the outer end of the slider 25. A damper 24 is fixedly connected between the bottom end of the slider 25 and the inner wall of the overhead wire body 12. A spring 27 is fixedly connected to the outer enclosure of the damper 24.

[0032] When it is necessary to wind the completed overhead wire body 12, the operator passes a plurality of overhead wire bodies 12 to be processed through the surfaces of the rotating roller 4 and a plurality of reserved grooves 10 in sequence. Then, the overhead wire body 12 is connected to the winding roller 8. Subsequently, the motor 5 is turned on to make the winding roller 8 rotate. When the rotation speed of the winding roller 8 increases, the tension of the plurality of overhead wire bodies 12 will become larger. At this time, the plurality of overhead wire bodies 12 will press the spring 27, causing the spring 27 to compress. Then, a pair of sliders 25 will move vertically downward along the inner wall of the chute 11. Since the adjusting roller 9 is located between the pair of sliders 25, the adjusting roller 9 will also move vertically downward, causing the chute 11 on the surface of the reserved groove 10 to move downward, thereby reducing the tension of the overhead wire body 12. When the adjusting roller 9 continues to move downward under the action of the tension of the overhead wire body 12 until the pressing plate 26 at the outer end of the slider 25 contacts the alarm button 23, then the alarm button 23 will be turned on under the pressing of the pressing plate 26. Since the alarm 22 is electrically connected to the alarm button 23, the alarm 22 will be activated and give an alarm, reminding the staff that the tension of the overhead wire body 12 is too large, and the motor 5 should be controlled in time to reduce the rotation speed of the winding roller 8. When the rotation speed of the winding roller 8 is too small, the tension of the plurality of overhead wire bodies 12 will become smaller. At this time, the plurality of overhead wire bodies 12 will, under the action of the elastic force of the spring 27, cause a pair of sliders 25 to move vertically upward along the inner wall of the chute 11. Since the adjusting roller 9 is located between the pair of sliders 25, the adjusting roller 9 will also move vertically upward, causing the chute 11 on the surface of the reserved groove 10 to move upward, thereby increasing the tension of the overhead wire body 12 until the pressing plate 26 at the outer end of the slider 25 contacts another alarm button 23. Then, the other alarm button 23 will be turned on under the pressing of the pressing plate 26. Since the alarm 22 is electrically connected to the alarm button 23, the other alarm 22 will be activated and give an alarm, reminding the staff that the tension of the overhead wire body 12 is too small at this time, and the motor 5 should be controlled in time to increase the rotation speed of the winding roller 8 to avoid the situation of the overhead wire body 12 being bent.

[0033] Please refer to Figures 1-3 As shown in [figure number not provided], a pair of third fixing plates 7 are fixedly connected to the top of the operating table 1. A winding roller 8 is rotatably connected between the pair of third fixing plates 7. A motor 5 is fixedly connected to the outer end of one of the third fixing plates 7. An adjusting roller 9 is rotatably connected between a pair of sliders 25. A plurality of reserved grooves 10 communicating with the outside are formed at the outer end of the adjusting roller 9. The inner wall of the reserved groove 10 is made of a smooth material, and an overhead wire body 12 is arranged inside the reserved groove 10.

[0034] The inner wall of the reserved groove 10 of this solution is made of a smooth material, which can be plastic or other materials, and can reduce the friction between the overhead wire body 12 and the reserved groove 10. The motor 5 can control the rotation speed of the winding roller 8.

[0035] Working principle: When it is necessary to wind the completed overhead wire body 12, the operator passes multiple overhead wire bodies 12 to be processed through the surfaces of the rotating roller 4 and multiple reserved grooves 10 in sequence, then connects the overhead wire body 12 to the winding roller 8, and then turns on the motor 5 to make the winding roller 8 rotate. When the rotation speed of the winding roller 8 increases, the tension of multiple overhead wire bodies 12 will increase. At this time, multiple overhead wire bodies 12 will press the spring 27, causing the spring 27 to compress. Then, a pair of sliders 25 will move vertically downward along the inner wall of the chute 11. Since the adjusting roller 9 is located between a pair of sliders 25, the adjusting roller 9 will also move vertically downward, causing the chute 11 on the surface of the reserved groove 10 to move downward, thereby reducing the tension of the overhead wire body 12. When the adjusting roller 9 continues to move downward under the action of the tension of the overhead wire body 12 until the pressing plate 26 at the outer end of the slider 25 contacts the alarm button 23, then the alarm button 23 will be turned on under the pressing of the pressing plate 26. Since the alarm 22 is electrically connected to the alarm button 23, the alarm 22 will be activated and give an alarm, reminding the staff that the tension borne by the overhead wire body 12 is too large, and the rotation speed of the winding roller 8 should be reduced by controlling the motor 5 in time.

[0036] The above is only the preferred specific implementation manner of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
