Technical Field

[0001] This utility model relates to the field of power maintenance technology, specifically a fast cable core-pulling device for power maintenance. Background Technology

[0002] Cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. In a broad sense, cables are also simply referred to as wires and cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated conductors, and their respective possible covering layers, overall protective layer, and outer sheath.

[0003] The patent publication number CN212392593U discloses a fast cable core-pulling device for power maintenance, which includes a base plate and a clamping plate set in a suitable position. One end of the upper surface of the base plate is provided with a drive mechanism for providing power for fast core-pulling of the cable. A separation mechanism for peeling off the cable sheath is provided between the base plate and the clamping plate, which cooperates with the drive mechanism.

[0004] As described above, existing fast cable core-pulling equipment for power maintenance uses two blades to peel off the cable sheath during use. This method is convenient for peeling the sheath at the cable end, but during power maintenance, problems may occur in the middle of the cable, requiring the middle part to be peeled and core-pulled. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This high-speed cable core-pulling device for power maintenance offers two technical solutions:

[0024] The first embodiment includes a base plate 1 and four support feet 2 fixed at the four corners of the bottom of the base plate 1. A core-pulling mechanism is provided on the base plate 1. The core-pulling mechanism includes a moving and rotating component 3, a radial cutting component 4 and an axial cutting component 5.

[0025] Both the radial cutting component 4 and the axial cutting component 5 are mounted on the movable rotating component 3. The structural design of the movable rotating component 3 allows the radial cutting component 4 to rotate and cut the radial sheath of the cable, and allows the axial cutting component 5 to move left and right and cut the axial sheath of the cable. Both the radial cutting component 4 and the axial cutting component 5 are composed of an adjusting component 6 and a blade 8. The blade 8 is mounted on the adjusting component 6 through the mounting component 7. The blade 8 can move up and down through the adjusting component 6 so that the blade can cut into the sheath of the cable.

[0026] The movable rotating component 3 includes two slide rails 31 fixed to the top of the base plate 1. A slide table 32 is slidably connected to the slide rail 31. A lower semi-circular support 33 is fixedly connected to the top of the slide table 32. An upper semi-circular support 34 is rotatably connected to the top of the lower semi-circular support 33. After the upper semi-circular support 34 covers the lower semi-circular support 33, it is locked by a locking bolt 35 so that the cable is in the circular cavity formed by the lower semi-circular support 33 and the upper semi-circular support 34. A semi-circular track 36 is fixedly connected to the right side of both the lower semi-circular support 33 and the upper semi-circular support 34. A slider 37 is slidably connected to the surface of the semi-circular track 36. A radial cutting component 4 is fixed to one side of the slider 37, and an adjustment component 6 is fixed to the other side of the lower semi-circular support 33.

[0027] Adjustment component 6 includes mounting base 61, which is fixedly connected to one side of slider 37. A lead screw 62 is threaded onto mounting base 61, and a guide rod 63 is slidably connected onto mounting base 61. Mounting component 7 is rotatably connected to one end of lead screw 62, and one end of guide rod 63 is fixedly connected to mounting component 7.

[0028] When removing the core from a cable during power maintenance, the core-removing mechanism, with the cooperation of the moving rotating component 3, the axial cutting component 5, and the radial cutting component 4, can strip the insulation and remove the core from the cable's end or middle section. This operation is convenient and quick, improving the practicality of the device.

[0029] The mounting assembly 7 includes an L-shaped plate 71. A groove 72 is provided on one side of the L-shaped plate 71, and a pressure plate 73 is slidably connected to the inner surface of the groove 72. A reset spring 74 for resetting the pressure plate 73 is fixedly connected between the pressure plate 73 and the inner wall of the groove 72. A fixing rod 75 is fixedly connected to the inner side of the L-shaped plate 71, and the pressure plate 73 is slidably connected to the surface of the axial cutting assembly 5. A cam handle 76 is rotatably connected to the surface of the fixing rod 75 at one end of the outer side of the pressure plate 73. The cam handle 76 rotates and pushes the pressure plate 73 to press against the blade 8. A positioning rod 77 is fixedly connected to the inner side of the pressure plate 73. A positioning groove 78 corresponding to the position of the positioning rod 77 is provided inside the blade 8, and a guide groove 79 corresponding to the position of the fixing rod 75 is also provided on the blade 8.

[0030] The blade 8 in the axial and radial cutting assembly is installed through the mounting assembly 7, which facilitates quick disassembly and installation of the blade 8 after it becomes dull, further improving the convenience of using the device.

[0031] In use, place the cable on the lower semicircular support 33, rotate the upper semicircular support 34 so that the upper semicircular support 34 covers the cable, and tighten the locking bolt 35. Rotate the screw 62 to move the blade 8 downward so that the blade 8 enters the cable sheath. Rotate the radial cutting assembly 4 so that the blade 8 cuts the sheath along the radial direction of the cable. Then move the slide table 32 so that the blade 8 on the axial cutting assembly 5 cuts the cable sheath axially. Finally, perform a radial cut through the radial cutting assembly 4. At this time, the middle sheath of the cable can be peeled off, and the core removal operation is completed. In addition, when the blade 8 needs to be replaced, rotate the cam handle 76 to release the pressure plate 73 from the blade and move it away from the blade 8. At this time, the blade 8 can be removed.
