Description

Technical Field

[0001] This utility model belongs to the field of cable stripping technology, and relates to an efficient stripping device for power construction cables. Background Technology

[0002] High-efficiency cable stripping equipment for power construction is a specialized tool used to quickly and accurately remove the outer insulation or sheath of cables, thereby improving construction efficiency and reducing manual labor intensity. It is widely used in substation construction, cable laying, and power emergency repair, ensuring the reliability and safety of cable connections.

[0003] For example, patent (CN222530111U) discloses a cable stripping device, which describes that "the cutting wheel includes an internal gear, a blade is fixedly connected to the middle of the internal gear, outer wheels are added to both sides of the internal gear, clamping springs are added to the outer sides of the outer wheels, and retaining rings are added to both sides of the clamping springs. This utility model has a blade fixedly connected to the middle of the internal gear, outer wheels added to both sides of the internal gear, clamping springs added to the outer sides of the outer wheels, and retaining rings added to both sides of the clamping springs. The outer retaining rings are fixedly sleeved on the shaft, and the inner retaining rings are movably sleeved on the shaft. When a cable is to enter, the cable can contact the outer wheel before contacting the blade. At the same time, the clamping springs on both sides tighten the outer wheel, which will generate greater friction between the outer wheel and the cable. The outer wheel applies external force to the cable to send the cable into the blade."

[0004] When using the above technology, the following technical problems were found in the existing technology: During operation, one end of the cable needs to be inserted into the cutting wheel group, the outer sheath is stripped by rotating blades, and the cable is driven to move continuously by the friction between the internal gear and the cable. At the same time, the cable is supported and guided by the platform and the stop bar. However, this design has significant structural deficiencies - the cable tail end lacks an effective guidance and support system. Specifically, after the cable is cut, the tail end is in a free hanging state due to the loss of fixed constraints. Under the action of gravity, it droops and bends, causing the contact surface between it and the platform to deform, forming a nonlinear stress state. As a result, under the action of gravity, the cable and the internal gear generate a reverse force, which destroys the dynamic meshing relationship between the cable and the gear. Utility Model Content

[0005] The technical problem this invention aims to solve is that, during operation, the device requires one end of the cable to be inserted into the cutting wheel assembly, and the outer sheath is peeled off by rotating blades. The cable is driven to move continuously by the friction between the internal gear and the cable, while the platform and stop bar provide support and guidance. However, this design has significant structural deficiencies—the cable tail end lacks an effective guidance and support system. Specifically, after the cable is cut, the tail end is in a free-hanging state due to the loss of fixed constraints. Under the action of gravity, it droops and bends, causing deformation of the contact surface with the platform, resulting in a nonlinear stress state. Consequently, under the action of gravity, the cable and the internal gear generate a reverse force, disrupting the dynamic meshing relationship between the cable and the gear.

[0006] This utility model discloses a high-efficiency cable stripping device for power construction, comprising a processing platform, a first servo motor mounted on one side of the top of the processing platform, a support plate fixedly connected to one side of the top of the processing platform, a first driven shaft rotatably connected to the top of the support plate, the output end of the first servo motor rotatably connected to the middle of the support plate, two sets of first synchronous pulleys mounted in the middle of the first driven shaft, the other ends of the two first synchronous pulleys mounted to the output end of the first servo motor, gears mounted on the ends of the first driven shaft and the first servo motor output away from the first servo motor, and cutting blades fixedly connected to the middle of the gears, and a guide support assembly provided on one side of the processing platform.

[0007] The guide support assembly includes an extension platform, a bracket, a drive shaft, a support block, multiple sets of support rods, a hollow plate, and a second servo motor. The extension platform is fixed to the side of the processing platform near the gear. The bracket is fixed to the bottom side of the extension platform. The second servo motor is installed in the middle of the bracket. One end of the drive shaft is connected to the output end of the second servo motor. The support block is fixed to the middle of the bottom of the extension platform. The middle part of the drive shaft is rotatably connected to the middle of the support block. The bottom of each support rod is fixed to the top of the extension platform. The hollow plate is fixed to the top of the support rod. A heat dissipation assembly is provided on one side of the middle of the extension platform.

[0008] The guide support assembly also includes a reciprocating lead screw, a rectangular slot, a second synchronous pulley set, and a threaded sleeve. The reciprocating lead screw is rotatably connected to the middle of the hollow plate. The rectangular slot is opened in the middle of the extension platform near the bracket. One end of the second synchronous pulley set is installed at the end of the reciprocating lead screw near the bracket, and the other end of the reciprocating lead screw is installed at the output end of the bracket. The threaded sleeve is threadedly connected to the middle of the reciprocating lead screw.

[0009] The guide support assembly also includes a T-shaped plate, two sets of limiting slide rods and two sets of limiting slide grooves. The bottom end of the T-shaped plate is fixed to the top of the threaded sleeve. The top ends of the two limiting slide rods are respectively fixed to the two ends of the T-shaped plate. The two limiting slide grooves are respectively opened on both sides of the hollow plate. The bottom of the two limiting slide rods are respectively slidably connected to the middle of the two sets of limiting slide grooves.

[0010] The heat dissipation assembly includes a hollow wall tube, a worm gear, a cross support frame, and a second driven shaft. The hollow wall tube is installed on the side of the extension platform near the gear. The worm gear is fixed to the end of the drive shaft away from the second servo motor. The cross support frame is fixed to the middle of the hollow wall tube. The second driven shaft is rotatably connected to the middle of the cross support frame.

[0011] The heat dissipation assembly also includes a worm gear, multiple sets of fan blades, and multiple sets of baffles. The worm gear is fixed to one end of the second driven shaft near the worm, and the worm gear meshes with the worm. The fan blades are all fixed to the middle of the second driven shaft, and the baffles are all connected to one end of the hollow wall tube near the gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the guide support component, the cable tail that is undergoing stripping can be guided and supported, thereby reducing the free hanging state of the cable tail due to the loss of fixed constraint during stripping. Under the action of gravity, the cable will droop and bend. This drooping and bending can easily cause the cable to be in a non-linear stress state, which in turn causes a reverse force between the cable and the internal gear. This reverse force is opposite to the force that originally drives the cable to move, thereby destroying the original stable dynamic meshing relationship between the cable and the gear. This destruction of the dynamic meshing relationship can not only easily lead to the cable moving unevenly, such as jamming and shaking, but also increase the friction and wear between the gear and the cable, reduce the operating efficiency and service life of the device, and in severe cases, may even cause equipment failure, affecting the normal progress of power construction projects.

[0013] By setting up heat dissipation components, the overheating caused by friction when gears are working continuously can be reduced, thereby reducing thermal fatigue damage to gears and suppressing the occurrence of changes in meshing clearance caused by thermal expansion, which can lead to vibration, noise, and reduced transmission accuracy.

[0026] Example 1

[0027] like Figures 1-5As shown, a high-efficiency cable stripping device for power construction includes a processing platform 1. A first servo motor 11 is installed on one side of the top of the processing platform 1. A support plate 12 is fixedly connected to one side of the top of the processing platform 1. A first driven shaft 13 is rotatably connected to the top of the support plate 12. The output end of the first servo motor 11 is rotatably connected to the middle of the support plate 12. Two sets of first synchronous pulleys 14 are installed in the middle of the first driven shaft 13. The other ends of the two sets of first synchronous pulleys 14 are installed at the output end of the first servo motor 11. Gears 15 are installed at the ends of the first driven shaft 13 and the first servo motor 11 away from the first servo motor 11. Cutting blades 16 are fixedly connected to the middle of the gears 15. A guide support group is provided on one side of the processing platform 1.

[0028] The guide support assembly includes an extension platform 2, a bracket 21, a drive shaft 22, a support block 23, multiple sets of support rods 24, a hollow plate 25, and a second servo motor 26. The extension platform 2 is fixed to the side of the processing platform 1 near the gear 15. The bracket 21 is fixed to the bottom side of the extension platform 2. The second servo motor 26 is installed in the middle of the bracket 21. One end of the drive shaft 22 is connected to the output end of the second servo motor 26. The support block 23 is fixed to the middle of the bottom of the extension platform 2. The middle of the drive shaft 22 is rotatably connected to the middle of the support block 23. The bottom of each support rod 24 is fixed to the top of the extension platform 2. The hollow plate 25 is fixed to the top of the support rods 24. A heat dissipation assembly is provided on one side of the middle of the extension platform 2.

[0029] The guide support assembly also includes a reciprocating screw 3, a rectangular slot 31, a second synchronous pulley set 32, and a threaded sleeve 33. The reciprocating screw 3 is rotatably connected to the middle of the hollow plate 25. The rectangular slot 31 is opened in the middle of the extension platform 2 near the bracket 21. One end of the second synchronous pulley set 32 ​​is installed at the end of the reciprocating screw 3 near the bracket 21, and the other end of the reciprocating screw 3 is installed at the output end of the bracket 21. The threaded sleeve 33 is threadedly connected to the middle of the reciprocating screw 3.

[0030] The guide support assembly also includes a T-shaped plate 4, two sets of limiting slide rods 41 and two sets of limiting slide grooves 42. The bottom end of the T-shaped plate 4 is fixed to the top of the threaded sleeve 33. The top ends of the two limiting slide rods 41 are respectively fixed to the two ends of the T-shaped plate 4. The two limiting slide grooves 42 are respectively opened on both sides of the hollow plate 25. The bottom of the two limiting slide rods 41 are respectively slidably connected to the middle of the two sets of limiting slide grooves 42.

[0031] When it is necessary to peel the cable used for power construction, one end of the cable can be aligned with the junction of the two sets of gears 15, and the cable tail can be placed on the T-shaped plate 4. Then, the first servo motor 11 and the second servo motor 26 are driven to work simultaneously. When the first servo motor 11 is working, its output end will rotate in the middle of the support plate 12. At the same time, through the setting of the two sets of first synchronous pulleys 14, the torque output by the first servo motor 11 can be transmitted to the first driven shaft 13, so that the first servo motor 11 and the first driven shaft 13 move synchronously, thereby driving the gears 15 and the cutting blade 16 to rotate. The rotation of the gears 15 can push the cable to move, and the rotation of the cutting blade 16 can cut the cable sheath, thus performing the peeling work.

[0032] When the second servo motor 26 is working, it will drive the drive shaft 22 to rotate in the middle of the support block 23. At this time, the second synchronous pulley group 32 can synchronously drive the reciprocating screw 3 to rotate in the middle of the hollow plate 25. During the rotation, the reciprocating screw 3 will drive the threaded sleeve 33, the T-shaped plate 4 and the limiting slide rod 41 to move synchronously. When the limiting slide rod 41 moves, it will slide in the middle of the limiting slide groove 42, thereby limiting the movement trajectory of the T-shaped plate 4, so that it drives the cable tail to slide linearly towards the gear 15, thereby guiding and supporting the cable tail.

[0033] This step, through the setting of the guide support component, guides and supports the cable tail during the stripping process, thereby reducing the likelihood of the cable tail being in a free-hanging state due to the loss of fixed constraints during stripping. This prevents the cable from drooping and bending under gravity, which can easily lead to a non-linear stress state and cause a reverse force between the cable and the internal gear. This reverse force is opposite to the force that originally drives the cable movement with gear 15, thus disrupting the original stable dynamic engagement between the cable and gear 15. This disruption of the dynamic engagement not only easily leads to uneven cable movement, causing jamming and vibration, but also increases friction and wear between gear 15 and the cable, reducing the operating efficiency and service life of the device. In severe cases, it may even cause equipment failure and affect the normal progress of power construction projects.

[0034] Example 2

[0035] like Figure 1 , Figure 2 and Figure 6 As shown, the heat dissipation assembly includes a hollow wall tube 5, a worm gear 51, a cross support frame 52, and a second driven shaft 53. The hollow wall tube 5 is installed on the side of the extension platform 2 near the gear 15. The worm gear 51 is fixed to the end of the drive shaft 22 away from the second servo motor 26. The cross support frame 52 is fixed to the middle of the hollow wall tube 5. The second driven shaft 53 is rotatably connected to the middle of the cross support frame 52.

[0036] The heat dissipation assembly also includes a worm gear 6, multiple sets of fan blades 61 and multiple sets of baffles 7. The worm gear 6 is fixed to one end of the second driven shaft 53 near the worm 51, and the worm gear 6 and the worm 51 mesh with each other. The fan blades 61 are all fixed to the middle of the second driven shaft 53, and the baffles 7 are all connected to one end of the hollow wall tube 5 near the gear 15.

[0037] During operation, when the second servo motor 26 drives the drive shaft 22 to rotate, the drive shaft 22 will simultaneously drive the worm 51 to rotate. Since the worm 51 and the worm wheel 6 are in a meshing state, the rotation of the worm 51 will drive the worm wheel 6 to rotate. When the worm wheel 6 rotates, it will drive the second driven shaft 53 to rotate in the middle of the cross support frame 52. The rotation of the second driven shaft 53 will synchronously drive the fan blade 61 to rotate. The rotation of the fan blade 61 can generate a certain amount of wind force, thereby cooling the gear 15. In addition, the baffle 7 can protect the components inside the hollow wall tube 5, reducing the possibility of debris falling into the hollow wall tube 5 during peeling, which could affect the normal operation of the internal components of the hollow wall tube 5.

[0038] This step, through the setting of heat dissipation components, can reduce the overheating phenomenon caused by friction when the gear 15 is working continuously, thereby reducing the thermal fatigue damage of the gear 15, and suppressing the occurrence of changes in meshing clearance caused by thermal expansion, which may lead to vibration, noise and reduced transmission accuracy.
