Description

Technical Field

[0001] The present invention relates to the technical field of cables, and particularly to a wire stripping device for power supply cable faults. Background Art

[0002] During the fault detection and repair of power supply cables, stripping the insulation layer or sheath layer of the cable is a crucial pretreatment step. Traditional wire stripping operations mostly rely on manual use of knives or simple tools, which have problems such as low efficiency, poor incision accuracy, and easy damage to internal conductors. Especially when dealing with cables with large cross-sections or multi-layer structures, the operation difficulty increases significantly. In the prior art, some semi-automatic or fully automatic wire stripping devices have been applied to the cable processing field.

They only support single wire stripping modes in the longitudinal or circumferential direction and cannot meet the requirements of complex fault scenarios. Therefore, a wire stripping device for power supply cable faults is proposed. Summary of the Invention

Detailed implementation manners

[0026] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , the embodiments of the present invention provide a technical solution: a wire stripping device for power supply cable faults, including a bottom plate 1 and a top plate 5. The top plate 5 is placed above the bottom plate 1, and an adjusting mechanism is provided between the top plate 5 and the bottom plate 1. A fixed seat 6, a cutting mechanism 9 and a guide frame 10 are installed on the top surface of the top plate 5. The cutting mechanism 9 is arranged between the guide frame 10 and the fixed seat 6. A through hole 8 is opened on the top surface of the top plate 5 and on one side of the cutting mechanism 9;

[0028] The cutting mechanism 9 includes a fixing plate 18, a positioning ring 19 and an adjusting disc 22. The positioning ring 19 is fixedly installed in the middle of the fixing plate 18. The adjusting disc 22 is installed inside the positioning ring 19. A positioning strip 28 is arranged near the edge of the surface of the adjusting disc 22 and is rotationally connected to the positioning ring 19 through the positioning strip 28. A number of teeth 29 are evenly arranged on the outer wall of the adjusting disc 22. In the middle of the top surface of the fixing plate 18, a fixing box 21 is installed. A motor three 20 is arranged on the outer wall of the fixing box 21. The power output end of the motor three 20 extends into the interior of the fixing box 21 and is connected with a gear one 27. The gear one 27 is meshed and connected with the teeth 29. Cutting boxes 24 are symmetrically installed on the surface of the adjusting disc 22. Cutting discs 23 are installed on the opposite surfaces of the two cutting boxes 24. The cutting discs 23 are electric cutting discs 23. A through hole 25 is opened in the middle of the surface of the adjusting disc 22. A cable passes through the through hole 25. The cutting mechanism 9 drives the double cutting discs 23 to move synchronously through the adjusting disc 22, supports the free switching between circumferential cutting and longitudinal cutting, and meets the requirements of different wire stripping scenarios; the gear transmission system (the gear one 27 is meshed with the teeth 29) combines with the steering gear 31 to control the angle of the cutting disc 23, realizes the fine adjustment of the cutting depth, and avoids damaging the wire core;

[0029] In the middle of the surface of the guiding frame 10, a guiding hole 11 is arranged. An upper guiding roller 12 and a lower guiding roller 40 are connected in the guiding hole 11. The upper guiding roller 12 and the lower guiding roller 40 guide the cable.

[0030] Further improved, two groups of adjusting mechanisms are provided and symmetrically distributed on both sides above the bottom plate 1. The adjusting mechanism includes a connecting plate 4, a driving rod 3, an adjusting box 17, an upper support rod 15 and a lower support rod 2.

The ends of the upper support rod 15 and the lower support rod 2 are rotationally connected to the connecting plate 4. Connecting rods 16 are respectively arranged on both sides of the adjusting box 17. The ends of the connecting rods 16 are fixedly connected to the connecting shaft. Threads are symmetrically arranged on the surface of the driving rod 3. A threaded hole is opened on the surface of the adjusting box 17 and is threadedly connected with the driving rod 3 through the threaded hole. After the driving rod 3 rotates, it drives the two adjusting boxes 17 to move. When the adjusting boxes 17 move towards the middle or both sides at the same time, the top plate 5 is vertically adjusted through the upper support rod 15 and the lower support rod 2.

[0031] Further improved, the cutting box 24 is in a T-shaped structure, and a telescopic cylinder 26 is embedded at the end. The telescopic cylinder 26 is preferably a hydraulic cylinder. A connecting frame 34 is arranged at the front end of the cutting box 24. The cutting disc 23 is rotatably installed inside the connecting frame 34. A quadrangular prism 30 is fixedly installed on the back of the connecting frame 34. The end of the quadrangular prism 30 extends into the inside of the cutting box 24 and is rotationally connected to the telescopic end of the telescopic cylinder 26. After the telescopic cylinder 26 extends the telescopic rod, it drives the quadrangular prism 30, and the quadrangular prism 30 drives the connecting frame 34 to adjust the position of the cutting disc 23.

[0032] Further improved, a sleeve 32 is rotatably connected inside the cutting box 24. The sleeve 32 is sleeved outside the quadrangular prism 30 and is movably connected to the quadrangular prism 30. A third gear 35 is fixed on the outer wall of the sleeve 32.

The power output end of the steering gear 31 extends to the inside of the cutting box 24 and is provided with a second gear 33. The second gear 33 is meshed with the third gear 35. When the steering gear 31 rotates, it drives the sleeve 32 to rotate through the second gear 33 and the third gear 35. After the sleeve 32 rotates, it drives the quadrangular prism 30 to rotate, thereby adjusting the angle of the cutting disc 23 and changing whether the cutting disc 23 performs longitudinal cutting, circumferential cutting or cutting at other angles.

[0033] Further improved, screw rods 37 are respectively connected to both sides inside the guide frame 10. Threaded sleeves 36 are threadedly connected to the screw rods 37. The two threaded sleeves 36 are respectively rotatably connected to both ends of the upper guide roller 12. Synchronous wheels 39 are installed at the upper ends of the screw rods 37. A synchronous chain 38 is used to connect between the two synchronous wheels 39. A first motor 13 is installed on one side of the top of the guide frame 10. The power output end of the first motor 13 is connected to the upper end of one of the screw rods 37. A second motor 14 is installed on the side wall of the guide frame 10. The power output end of the second motor 14 is connected to the end of the lower guide roller 40. After the first motor 13 is started, it drives the screw rod 37. After the two screw rods 37 rotate synchronously, they drive the upper guide roller 12 to move vertically, which can be adapted to cables of different diameters.

[0034] Further improved, the fixing seat 6 is of a U-shaped structure and a support roller 7 is rotatably connected inside. The support roller 7 supports and guides the cable.

[0035] Working principle: By rotating the driving rod 3, the two adjusting boxes 17 are driven to move. During the movement of the adjusting boxes 17, the top plate 5 is driven to perform vertical adjustment. After adjusting to a suitable height, the cable is passed through between the upper guide roller 12 and the lower guide roller 40, passes through the through hole 25 and is placed on the support roller 7. After starting the first motor 13, the second motor 14 and the telescopic cylinder 26, the first motor 13 drives the upper guide roller 12 to move downward through the screw rod 37. The upper guide roller 12 presses on the cable. After the second motor 14 is started, it drives the lower guide roller 40 to rotate, and conveys the cable forward. After the telescopic cylinder 26 is started, it drives the cutting disc 23 to move towards the cable and cuts the cable. After cutting is completed, it is exported. The angle of the cutting disc 23 can be adjusted by the steering gear 31 and adjusted to the circumferential cutting mode. In the circumferential cutting mode, the telescopic cylinder 26 is started to move the cutting disc 23 out, and the entire adjusting disc 22 is driven to rotate by the third motor 20, so as to achieve the circumferential cutting effect.

The components are all common standard parts or parts known to those skilled in the art.
