[0002] Electric wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electrical and magnetic energy. In a broad sense, electric wires and cables are also simply called cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as a collective body composed of the following parts: one or more insulated wire cores, and their respective possible coating layers, general protective layers, and outer protective layers. A cable may also have additional uninsulated conductors.

However, this device cannot effectively clamp and protect cables of different sizes. During the clamping process of the cable, claws need to be used, and their hard contact with the cable will cause scratches and damage to the cable outer skin. Moreover, when the cable is cut multiple times, the cable needs to be pulled, and the cable will also rub against this device during the pulling process, causing damage to the outer skin of the cable.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

Specific embodiments

[0022] The following will disclose multiple embodiments of the present utility model with illustrations. For the sake of clarity, many physical details will be described together in the following narrative. However, it should be understood that these physical details are not used to limit the present utility model. That is to say, in some embodiments of the present utility model, these physical details are not necessary. In addition, for the sake of simplifying the illustrations, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please refer to Figure 1 - Figure 4 , a power cable cutting device suitable for electric power of the present utility model includes two first double - threaded screws 3 and a base 1. On the outer surface of each first double - threaded screw 3, two push plates 4 are threadedly connected. Specifically, when the first double - threaded screw 3 is rotated, the first double - threaded screw 3 will drive the corresponding two push plates 4 to move horizontally towards or away from each other along the first double - threaded screw 3, and the distance from each push plate 4 to the center position of the corresponding first double - threaded screw 3 is equal. The inner wall of each push plate 4 is slidably connected with a push rod 5. The push rod 5 can move horizontally along the corresponding push plate 4. A limiting strip is fixedly connected to the outer surface of the push rod 5 to prevent the push rod 5 from rotating.

[0024] In this embodiment, a U-shaped plate 6 is fixedly connected to one end of each push rod 5 away from the corresponding push plate 4. The openings of the corresponding two U-shaped plates 6 face each other. A clamping wheel 10 is rotatably connected to the inner wall of each U-shaped plate 6. The clamping wheel 10 can rotate within the corresponding U-shaped plate 6. The cable can be clamped through the mutual cooperation of the corresponding two clamping wheels 10. A spring 7 is sleeved on the outer surface of each push rod 5. The arrangement of the spring 7 can endow the corresponding U-shaped plate 6 with a certain elasticity. One end of each spring 7 is fixedly connected to the corresponding push plate 4, and the other end is fixedly connected to the corresponding U-shaped plate 6. Specifically, the cable is clamped by the clamping wheel 10 through the opposite movement of the U-shaped plate 6. During this process, the spring 7 starts to be compressed, and the push rod 5 will move horizontally outward along the corresponding push plate 4, so as to prevent the cable from being damaged due to excessive clamping force. At the same time, while the cable is fixed, the cable can be pulled, and the cable will drive the clamping wheel 10 to rotate, so as to reduce the friction force on the cable.

[0025] In this embodiment, the outer surface of each first bidirectional screw 3 is rotatably connected to the base 1. A pulley 8 is fixedly connected to one end of each first bidirectional screw 3. The two pulleys 8 have the same model and are located on the same side of the base 1. A transmission belt 9 is arranged on one side of the base 1 close to the pulley 8. The transmission belt 9 is in transmission connection with the outer surfaces of the two pulleys 8. Specifically, the rotation of one of the first bidirectional screws 3 will drive the corresponding pulley 8 to rotate. Due to the transmission relationship between the transmission belt 9 and the two pulleys 8, the transmission belt 9 will drive the other first bidirectional screw 3 to rotate simultaneously through the other pulley 8.

[0026] In this embodiment, a motor 2 is fixedly installed on one side of the base 1 away from the pulley 8. The output end of the motor 2 is fixedly connected to one of the first bidirectional screws 3. A control switch 16 is fixedly installed on the outer surface of the base 1. Specifically, the start of the motor 2 will drive the corresponding first bidirectional screw 3 to rotate, and the control switch 16 can control the circuit in this device through the PLC.

[0027] In this embodiment, four fixed columns 11 are fixedly connected to the upper surface of the base 1. Four chutes are opened on the upper surface of the base 1. Each chute is located below the corresponding fixed column 11. A second bidirectional screw 12 is rotatably connected to the inner wall of each fixed column 11. The bottom end of each second bidirectional screw 12 is rotatably connected to the base 1. Specifically, the second bidirectional screw 12 can rotate within the corresponding fixed column 11.

[0028] Look back Figure 3, a fixing frame 14 is fixedly connected to the outer surface of the base 1. The outer surface of each second bidirectional screw 12 is rotatably connected to the fixing frame 14. The top of each second bidirectional screw 12 is fixedly connected to a first gear 13. Specifically, the bottom surface of each first gear 13 is rotatably connected to the fixing frame 14. The rotation of the first gear 13 will drive the corresponding second bidirectional screw 12 to rotate.

[0029] As Figure 1 - Figure 3 shown, a second gear 15 is rotatably connected to the upper surface of the fixing frame 14. The outer surface of the second gear 15 meshes with all four first gears 13. The second gear 15 is rotated by a PLC controlled by a control switch 16. The rotation of the second gear 15 will drive the four first gears 13 to rotate. Above the base 1, there are four clamping plates 17. The outer surface of each clamping plate 17 is slidably connected to the corresponding fixing column 11 or the base 1. The distance from each clamping plate 17 to the center position of the corresponding second bidirectional screw 12 is equal. The inner wall of each clamping plate 17 is threadedly connected to the corresponding second bidirectional screw 12. Specifically, the rotation of the second bidirectional screw 12 will drive the corresponding clamping plate 17 to move vertically along the second bidirectional screw 12, so as to clamp and fix cables of different sizes through the clamping plates 17, facilitating cutting.

[0030] As Figure 4 shown, a hydraulic rod 18 is fixedly installed on the bottom surface of the fixing frame 14. The bottom end of the hydraulic rod 18 is fixedly connected to a connecting block 19. The outer surface of the connecting block 19 is rotatably connected to a cutting blade 20. Specifically, the hydraulic rod 18 is controlled by the control switch 16. The hydraulic rod 18 will push the cutting blade 20 to move vertically through the connecting block 19, and the cable is cut by the cutting blade 20.
