Description

Technical Field

[0001] This invention relates to the field of cable stripping, specifically to a cable outer sheath rotary stripping clamp. Background Technology

[0002] In power cable laying, joint fabrication, terminal installation, and waste cable recycling, it is often necessary to separate the multi-layered structure of the cable. For high-voltage or ultra-high-voltage cables with metal sheaths and steel tape armor, the outer sheath is usually made of dense materials such as polyethylene or polyvinyl chloride, which is tightly bonded to the internal main insulation layer and metal sheath. During construction, after the main insulation layer and aluminum sheath are circumferentially cut, the discarded outer sheath section needs to be removed from the cable body. Existing technologies have some electric or manual circumferential cutting tools that can achieve circumferential cutting of the sheath. However, these tools mostly only complete the cutting process. After the cutting is completed, there is still a large static friction and residual adhesive force between the outer sheath and the internal layer structure. Other tools such as pry bars and pliers are needed for auxiliary separation. Short-section, short-distance discarded sheath sections can be easily removed, but for large-section, long-distance discarded sheath sections, the operation is cumbersome and prone to damage to the internal structure of the cable due to uneven force. At the same time, manual removal is extremely laborious and inefficient.

[0003] To address this, a cable outer sheath rotary stripping clamp is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a cable outer sheath peeling pliers to solve the problems of cumbersome operation procedures, extremely laborious manual removal, and low work efficiency when peeling large-section, long-distance discarded sheath sections.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A cable sheath peeling pliers includes a lower clamping tube, one end of which is provided with a short clamp. A connecting sleeve is installed between the lower clamping tube and the short clamp. One side of the short clamp is flat and has a through hole. A first pin is installed in the through hole. One side of the short clamp is fixedly installed to one end of the connecting sleeve by the first pin. The other end of the connecting sleeve is fixedly installed to the lower clamping tube by a threaded structure. A mounting hole is provided on the short clamp, and a second pin is rotatably connected in the mounting hole. A long clamp is provided above the short clamp and is rotatably connected to the short clamp by the second pin. A clamping plate is installed on both the long and short clamps. Connectors are installed between the clamping plates and the long and short clamps on both sides.

[0006] Currently, the commonly used tools for stripping cable sheaths are wire strippers or utility knives. While wire strippers can remove the cut outer sheath along with thin cables, they are often insufficient for stripping sheaths with a certain degree of hardness or thickness. This requires manual pulling of the sheath, which is time-consuming and labor-intensive, failing to meet the demands of modern construction for high efficiency and precision. The aforementioned equipment is primarily used for stripping cable sheaths. After the main insulation layer and aluminum sheath are cut, the equipment is used to clamp the discarded section of the sheath and rotate downwards to remove it, significantly saving manpower and ensuring efficient operation. In practice, workers must first determine the location of the cut cable sheath, then fit the gap between the long and short clamps onto the cut sheath, using connectors to ensure the clamping plate firmly holds the sheath. Next, grip the lower clamping tube tightly, causing the long and short clamps to engage firmly with each other under the action of the second pin, gripping the outer sheath tightly. Then, the operator slowly rotates the lower clamping tube around the cable as the central axis, causing the short and long clamps to rotate together. At this time, the clamping plates installed on the short and long clamps apply continuous and uniform pressure to the cable's outer sheath. As the rotation continues, the outer sheath is gradually peeled off along the cable's axis. No additional manual pulling is required during the peeling process, effectively avoiding the jamming and laborious problems of traditional tool operation. The entire operation process is smooth and seamless, greatly improving the convenience and efficiency of cable outer sheath peeling operations.

[0007] Preferably, the connector includes multiple connecting blocks. Both the long and short clamps have placement slots. Multiple sets of symmetrically arranged through-slots are formed on the side walls of both the long and short clamps, communicating with the central placement slot. An mounting block is fixedly installed on the clamping plate, rotatably connected to the connecting block, and a torsion spring is installed at the rotatable connection point. A sliding block is provided within the placement slot, with both sides of the sliding block slidably connected to the through-slot. The connecting block and the sliding block are fixedly installed. Multiple threaded holes are formed within the through-slot, each threaded hole being threadedly connected to a limit post. The sliding block is slidably connected to the limit post, and a compression spring is sleeved on the limit post, with both ends of the compression spring abutting against the placement slot and the sliding block, respectively.

[0008] When stripping cables of different diameters, multiple clamping plates connected to the long and short clamps continuously approach the cable sheath to be stripped. These clamping plates compress the cable sheath in the middle. When the cable diameter to be stripped is small, because the clamping plate in the middle of the long clamp is positioned opposite the clamping plate on the short clamp, during the actual clamping and rotating stripping process, the clamping plate on the short clamp will squeeze the clamping plate in the middle of the long clamp through the cable. When clamping a thin cable, the middle clamping plate will... By firmly pressing against the cable and continuing to squeeze, the mounting block and connecting block move the sliding block to its limit position. The clamping plates on both sides rotate under the action of the mounting block and connecting block, continuously pressing against the sidewalls of the cable. When clamping and stripping thicker cables, the cable presses against the clamping plates on both sides of the long clamp, squeezing them. However, when it moves to the designated position, the middle clamping plate also presses against the cable. This structure allows the device to effectively strip the main insulation layer from the aluminum sheath of cables of different diameters. This structural design allows the clamp to adapt to various cable sheath specifications, improving the versatility and flexibility of the equipment.

[0009] Preferably, the clamping plate has multiple evenly arranged toothed protrusions, the length direction of the toothed protrusions is perpendicular to the length direction of the pressing tube, the toothed protrusions on the clamping plate of the long clamp are oriented obliquely upward, and the toothed protrusions on the clamping plate of the short clamp are oriented obliquely downward.

[0010] This toothed protrusion design significantly increases the friction between the clamping plate and the cable sheath, effectively preventing cable slippage during rotational stripping and ensuring the stability and precision of the stripping action. Simultaneously, the toothed protrusions on the clamping plate of the long clamp are angled upwards, forming an inclined engagement angle with the cable surface. When the cable is subjected to rotational stripping force, the toothed protrusions can embed deeper into the sheath surface, generating an oblique gripping force. Meanwhile, the toothed protrusions on the short clamp, angled downwards, provide restraint from the opposite direction. Together, they create a "two-way interlocking" effect, maintaining a stable clamping state even on smooth or slightly oily cables, significantly improving the reliability of the stripping operation. This mutual interlocking tendency when the clamping plates compress the cable further enhances the clamping effect, preventing cable shifting or loosening during stripping, thereby improving the overall efficiency and quality of the stripping operation.

[0011] Preferably, two support columns are fixedly installed in the through groove of the long clamp head, and a movable plate is rotatably connected to the support column. The two ends of the movable plate abut against the sliding blocks on both sides, and the middle sliding block is divided into a left abutment position and a right abutment position. The two movable plates abut against the left abutment position and the right abutment position respectively. The bottom of the sliding block is provided with an arc-shaped chamfer, and the support column is located near the middle sliding block.

[0012] When the middle or side clamping plates are pressed and pushed to the designated position, the sliding block moves within the groove. The moving plate rotates around the support column, transferring the displacement of one side of the sliding block to the other through leverage, allowing the two sliding blocks to move closer or further apart synchronously, ensuring a uniform distribution of clamping force on the cable. The rounded chamfer design reduces frictional resistance between the sliding block and the bottom of the groove, making the sliding process smoother and avoiding unstable clamping force due to jamming. This structural design not only simplifies the operation but also automatically adjusts the clamping position when clamping cables of different diameters, preventing the side or middle clamping plates from contacting each other via springs, which would reduce friction. The moving plate locks the clamping plates, maintaining clamping force on the middle cable, thus improving the versatility and ease of use of the caliper.

[0013] Preferably, the clamping plate has multiple threaded holes, which are located on both sides of the clamping plate. A fixing bolt is threaded into each threaded hole, and a clamping pin is placed inside the threaded hole. The fixing bolt and the clamping pin are fixedly installed together.

[0014] The clamping pin is made of high-hardness wear-resistant alloy, and its end is machined into a pointed cone shape so that it can be inserted into the cable shell, increasing the contact area with the cable's outer sheath. When the main insulation layer of the cable is peeled off without removing the inner aluminum sheath, the outer main insulation layer made of rubber material will generate a lot of friction with the aluminum sheath. Therefore, the clamping pin increases the friction. The length of the clamping pin extending out of the clamping plate can be adjusted by rotating the fixing bolt. When dealing with cable outer sheaths of different thicknesses, the clamping depth of the clamping pin can be flexibly adjusted to ensure that the clamping effect of the caliper on the cable remains stable during the peeling process, effectively preventing the cable from slipping or shifting during the peeling operation, and further improving the accuracy and safety of the peeling operation.

[0015] Preferably, the second pin is fixedly installed with the long collet, and a locking gear is fixedly installed on the second pin. A support column is also provided in the through groove of the short collet. The movable plate is rotatably connected to the support column. One end of the movable plate abuts against the sliding block, and a locking tooth is fixedly installed on the other end of the movable plate. When the connecting block pushes the movable plate to a designated position, the locking tooth on the movable plate engages with the locking gear. A locking post is threadedly connected to the short collet. By rotating the locking post, the locking tooth on the movable plate cannot engage with the locking gear.

[0016] This structural design achieves rapid locking and releasing of the calipers through mechanical linkage. When the operator pushes the connecting block to move the sliding block, the sliding block squeezes the moving plate to rotate around the support column, causing the cleats and locking gear to precisely engage. This fixes the relative positions of the long and short chucks. When peeling off the outer main insulation layer made of rubber, it prevents the operator from applying more pressure during the rotary cutting process, which would cause the outer main insulation layer to adhere more tightly to the aluminum sheath, making it difficult to peel off. When it is necessary to maintain the cleat spacing, simply rotate the locking pin, forcing it away from the moving plate, allowing the moving plate to flip. Conversely, when it is not necessary to maintain the cleat spacing, simply rotate the locking pin in the opposite direction, forcing it closer to the moving plate, preventing it from flipping. Furthermore, the tooth profile design of the locking gear and cleats has been optimized, using a helical tooth structure to enhance the stability of the meshing. Even during high-torque rotary cutting operations, reliable locking is maintained, effectively preventing accidental unlocking due to vibration or external impact, further ensuring the safety and stability of the peeling operation.

[0017] Preferably, the clamping plate includes a mounting plate and a toothed plate. The toothed plate is fixedly connected to the mounting plate by screws. The mounting plate is made of glass fiber reinforced nylon material, while the toothed plate is made of cast iron.

[0018] The mounting plate is made of glass fiber reinforced nylon, which possesses high mechanical strength and wear resistance, allowing it to withstand friction and impact during long-term use. The toothed plate is made of cast iron, utilizing its high strength and rigidity to ensure sufficient clamping force when engaging with the cable sheath, preventing slippage. Both are fixed together with screws, ensuring a stable connection and facilitating individual replacement of the toothed plate in case of wear or damage, thus reducing maintenance costs. Furthermore, the combination of materials for the mounting plate and toothed plate effectively balances weight reduction and structural strength, allowing the clamping plate to fulfill its functional requirements while also ensuring ease of operation.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Place the clamp onto the cut cable sheath, and use the connector to ensure that the clamping plate can firmly hold the sheath. The operator slowly rotates the lower clamping tube with the cable as the center axis. At this time, the clamping plates installed on the short and long clamps will apply continuous and uniform pressure to the cable sheath. As the rotation continues, the sheath will be gradually cut and peeled off along the axial direction of the cable. This effectively avoids the jamming and laborious problems of traditional tools. The entire operation process is smooth and efficient, greatly improving the convenience and efficiency of cable sheath peeling.

[0020] 2. During the actual clamping and rotating stripping process, the clamping plate installed on the short clamp will squeeze the clamping plate in the middle of the long clamp through the cable. At the same time, the continued squeezing will drive the sliding block to move through the mounting block and connecting block, so that the sliding block moves to the limit position. The clamping plates on both sides will rotate due to the action of the mounting block and connecting block, and continuously press against the side wall of the cable. This structural design allows the clamp to adapt to the outer sheath of various cable specifications, improving the versatility and flexibility of the equipment.

[0021] 3. When the middle or side clamping plates are pressed and pushed to the designated position, the sliding block moves in the groove. The moving plate rotates around the support column, and the displacement of the sliding block on one side is transmitted to the other side through the lever principle, so that the sliding blocks on both sides can move closer or further away at the same time. This avoids the clamping plates on both sides or in the middle from contacting each other through the spring, which would reduce the friction. The moving plate locks the clamping plate to keep the middle cable clamped, which improves the versatility and ease of use of the caliper. Attached Figure Description

[0024] Please see Figures 1 to 6 This invention provides a cable outer sheath rotary stripping clamp, the technical solution of which is as follows: A cable sheath peeling pliers includes a lower clamping tube 1, one end of which is provided with a short clamp 4. A connecting sleeve 2 is installed between the lower clamping tube 1 and the short clamp 4. One side of the short clamp 4 is flat and has a through hole 301. A first pin 3 is installed in the through hole 301. One side of the short clamp 4 is fixedly installed to one end of the connecting sleeve 2 by the first pin 3. The other end of the connecting sleeve 2 is fixedly installed to the lower clamping tube 1 by a threaded structure. A mounting hole 601 is provided on the short clamp 4, and a second pin 6 is rotatably connected in the mounting hole 601. A long clamp 5 is provided above the short clamp 4. The long clamp 5 is rotatably connected to the short clamp 4 by the second pin 6. A clamping plate 7 is installed on both the long clamp 5 and the short clamp 4. A connector is installed between the clamping plate 7 and the long clamp 5 and the short clamp 4 on both sides.

[0025] The connector includes multiple connecting blocks 8. A placement groove 15 is provided on both the long clamp 5 and the short clamp 4. Multiple sets of symmetrically arranged through-slide grooves 14 are provided on the side walls of both the long clamp 5 and the short clamp 4. The through-slide grooves 14 communicate with the middle placement groove 15. An mounting block 9 is fixedly installed on the clamping plate 7. The mounting block 9 is rotatably connected to the connecting block 8, and a torsion spring 21 is installed at the rotatable connection between the mounting block 9 and the connecting block 8. A sliding block 16 is provided in the placement groove 15. Both sides of the sliding block 16 are slidably connected to the through-slide groove 14. The connecting block 8 and the sliding block 16 are fixedly installed. Multiple threaded holes 10 are provided in the through-slide groove 14. Each threaded hole 10 is threadedly connected to a limit post 18. The sliding block 16 is slidably connected to the limit post 18. A compression spring 17 is sleeved on the limit post 18, and both ends of the compression spring 17 abut against the placement groove 15 and the sliding block 16, respectively.

[0026] The clamping plate 7 has multiple evenly arranged toothed protrusions. The length direction of the toothed protrusions is perpendicular to the length direction of the lower pressure tube 1. The toothed protrusions on the clamping plate 7 on the long clamp 5 are arranged obliquely upward, while the toothed protrusions on the clamping plate 7 on the short clamp 4 are arranged obliquely downward.

[0027] Two support columns 19 are fixedly installed in the through-slide groove 14 on the long chuck 5. A movable plate 20 is rotatably connected to the support column 19. The two ends of the movable plate 20 abut against the sliding blocks 16 on both sides. The middle sliding block 16 is divided into a left abutment position and a right abutment position. The two movable plates 20 abut against the left abutment position and the right abutment position respectively. The bottom of the sliding block 16 has an arc-shaped chamfer, and the support column 19 is located near the middle sliding block 16. The clamping plate 7 has multiple threaded holes 10, which are located on both sides of the clamping plate 7. The threaded holes 10 are threaded with fixing bolts 11, and clamping nails 22 are placed in the threaded holes 10. The fixing bolts 11 and clamping nails 22 are fixedly installed.

[0028] The second pin 6 is fixedly installed with the long collet 5. A locking gear 12 is fixedly installed on the second pin 6. A support column 19 is also provided in the through groove 14 on the short collet 4. The moving plate 20 is rotatably connected to the support column 19. One end of the moving plate 20 abuts against the sliding block 16, and the other end of the moving plate 20 is fixedly installed with a locking tooth 13. When the connecting block 8 pushes the moving plate 20 to the designated position, the locking tooth 13 on the moving plate 20 engages with the locking gear 12. A locking post 23 is threadedly connected to the short collet 4. By rotating the locking post 23, the locking tooth 13 on the moving plate 20 cannot engage with the locking gear 12. The clamping plate 7 includes a mounting plate 701 and a toothed plate 702. The toothed plate 702 is fixedly connected to the mounting plate 701 by screws. The mounting plate 701 is made of glass fiber reinforced nylon material, while the toothed plate 702 is made of cast iron.

[0029] In practical use: First, place the outer sheath of the cable to be stripped on the clamping plate 7 between the long clamp 5 and the short clamp 4. There are two cases for stripping the outer sheath. When stripping the main insulation layer and the aluminum sheath together, rotate the locking post 23 in the opposite direction to force the locking post 23 close to the moving plate 20, so that the moving plate 20 cannot be flipped. First, confirm the location of the outer sheath of the cable to be cut. Fit the gap formed between the long clamp 5 and the short clamp 4 onto the cut outer sheath of the cable, ensuring the clamping plate 7 firmly holds the outer sheath using the connector. Then, grip the lower clamping tube 1 tightly, causing the long clamp 5 and the short clamp 4 to engage with each other under the action of the second pin 6, firmly gripping the outer sheath. Next, the operator slowly rotates the lower clamping tube 1 around the cable as the central axis, causing the short clamp 4 and the long clamp 5 to rotate together. At this time, the clamping plate 7 installed on the short clamp 4 and the long clamp 5 applies continuous and uniform pressure to the cable's outer sheath. As the rotation continues, the outer sheath is gradually cut and peeled off along the cable's axial direction.

[0030] During the stripping process, multiple clamping plates 7 connected to the long clamp 5 and short clamp 4 continuously approach the cable sheath to be stripped. The clamping plates 7, positioned at multiple points, compress the cable sheath in the middle. When the diameter of the cable to be stripped is small, because the clamping plate 7 in the middle of the long clamp 5 is positioned opposite to the clamping plate 7 installed on the short clamp 4, during the actual clamping and rotating stripping process, the clamping plate 7 installed on the short clamp 4 will compress the clamping plate 7 in the middle of the long clamp 5 through the cable. This compresses the thin cable. During clamping, the middle clamping plate 7 will press tightly against the cable. At the same time, continued compression will drive the sliding block 16 to move through the mounting block 9 and connecting block 8, so that the sliding block 16 moves to the limit position. The clamping plates 7 on both sides will rotate due to the action of the mounting block 9 and connecting block 8, and continuously press against the side wall of the cable. When clamping and stripping a thick cable, the cable presses against the clamping plates 7 on both sides of the long clamp 5. At this time, the clamping plates 7 on both sides are squeezed. However, when they move to the designated position, the middle clamping plate 7 will also press against the cable.

[0031] Simultaneously, when the middle or side clamping plates 7 are pressed against and pushed to the designated position, the sliding block 16 moves within the groove, and the moving plate 20 rotates around the support column 19. Through the lever principle, the displacement of one side of the sliding block 16 is transmitted to the other side, allowing the two sliding blocks 16 to move closer or further apart synchronously, ensuring a uniform distribution of the clamping force of the clamping plate 7 on the cable. The rounded chamfer design reduces the frictional resistance between the sliding block 16 and the bottom of the groove, making the sliding process smoother and avoiding unstable clamping force due to jamming. This structural design not only simplifies the operation steps but also automatically adjusts the clamping position when clamping cables of different diameters, preventing the clamping plates 7 on both sides or in the middle from contacting each other through springs, thus reducing friction. The moving plate 20 locks the clamping plate 7, maintaining the clamping of the middle cable.

[0032] When only the main insulation layer is peeled off, the locking pin 23 is rotated to force the locking pin 23 away from the moving plate 20, allowing the moving plate 20 to flip. The outer main insulation layer made of rubber material will generate great friction between it and the aluminum sheath. Therefore, the friction is increased by the clamping pin 22. The length of the clamping pin 22 extending out of the clamping plate 7 can be adjusted by rotating the fixing bolt 11. When facing cable outer sheaths of different thicknesses, the clamping depth of the clamping pin 22 can be flexibly adjusted to ensure that the clamping effect of the caliper on the cable remains stable during the peeling process, effectively preventing the cable from slipping or shifting during the peeling operation, and further improving the accuracy and safety of the peeling operation.

[0033] This structural design achieves rapid locking and releasing of the caliper through mechanical linkage. When the operator pushes the connecting block 8 to move the sliding block 16, the sliding block 16 squeezes the moving plate 20 to rotate around the support column 19, so that the cleat 13 and the locking gear 12 are precisely engaged, thereby fixing the relative position of the long chuck 5 and the short chuck 4. When peeling off the outer main insulation layer made of rubber material, it avoids the operator from continuing to apply pressure during the rotary cutting process, which would cause the outer main insulation layer to adhere more tightly to the aluminum sheath, making it difficult to peel off the outer main insulation layer.

[0034] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
