Description

However, the existing automatic wire stripping device usually relies on the friction force of the clamping block to fix the wire, and the wire is easily damaged by torsion during the working process, especially when dealing with thin wires, the risk is more obvious.

The wire stripper 1 is hung on the wire and can automatically complete the screw-in stripping operation along the wire, exposing the wire core 18. The above technical features belong to mature prior art, and those skilled in the art can easily implement them based on existing technical solutions, and can make corresponding adjustments and optimizations according to actual needs. The wire stripper 1 described in this invention can refer to the technical content disclosed in existing patents CN112510591B "A Wire Stripping Device and Its Control Method" and CN111769485A "A Bearing-Supported Rotary Unit and an Automatic Stripper for Insulated Overhead Wires".

[0029] A support arm 3 is connected to the surface of the support part 2, and a mounting base 4 is connected to the end of the support arm 3 away from the support part 2.

[0030] A double-threaded screw 12 is rotatably mounted inside the mounting base 4, and a rolling bearing 14 is mounted on the side of the mounting base 4, with the double-threaded screw 12 rotatably mounted on the mounting base 4 via the rolling bearing 14. Preferably, two rolling bearings 14 are provided, distributed on both sides of the mounting base 4.

[0031] The mounting base 4 is internally connected to a guide rod 13, and the two sides of the surface of the guide rod 13 are respectively slidably connected to a first locking block 9 and a second locking block 10. The first locking block 9 and the second locking block 10 are both V-shaped structures, and the V-groove surfaces of the first locking block 9 and the second locking block 10 are arranged opposite to each other and correspond to each other.

[0032] The surface of the first locking block 9 and the second locking block 10 is provided with a first mounting hole 15 and a guide through hole 16, and a transmission nut is mounted in the first mounting hole 15, the double-threaded screw rod 12 is engagedly connected in the inside of the transmission nut mounted on the first locking block 9 and the second locking block 10, and the guide rod 13 is arranged in the inside of the guide through hole 16 provided on the surface of the first locking block 9 and the second locking block 10.

[0033] The surface of the first locking block 9 and the second locking block 10 is provided with a plurality of second mounting holes 17, and a roller 11 is rotatably mounted in the inside of the second mounting hole 17. The roller 11 is mounted in a manner perpendicular to the surface of the first locking block 9 and the second locking block 10.

[0034] The surface of the mounting seat 4 is provided with a driving assembly 5, and the driving assembly 5 is used for driving the double-threaded screw rod 12 to rotate.

[0035] The surface of the first locking block 9 is provided with an infrared sensor 8.

[0036] In an embodiment of the present application, the present application provides a rotary wire peeler with a wire locking function, mainly comprising a rotary wire peeler 1, which is hung on the wire and can automatically complete the rotary stripping operation along the wire to strip the wire insulation layer and expose the wire core 18. The surface of the peeler 1 is provided with a supporting part 2 connected to a mounting seat 4 through a supporting arm 3, and the mounting seat 4 is the core structure of the entire locking device and is used for bearing functional components such as the double-threaded screw rod 12, the guide rod 13, the first locking block 9 and the second locking block 10. The double-threaded screw rod 12 is rotatably mounted in the inside of the mounting seat 4 and is realized low-friction rotation through a rolling bearing 14, so as to improve the operation efficiency of the locking assembly. The guide rod 13 penetrates the mounting seat 4 and is slidably connected with the guide through hole 16 of the first locking block 9 and the second locking block 10, thereby providing accurate guidance for the linear movement of the locking block.

[0037] The first locking block 9 and the second locking block 10 are both V-shaped structures, and the V-groove surfaces thereof are oppositely arranged to form a stable wire clamping area. The double-threaded screw rod 12 is engagedly connected with the transmission nut on the surface of the locking block, and under the action of the driving assembly 5, the double-threaded screw rod 12 rotates to drive the first locking block 9 and the second locking block 10 to move towards or away from each other along the guide rod 13. When the locking blocks move towards each other, the wire can be firmly clamped; when the locking blocks move away from each other, the wire is loosened and the operation is completed. The inside of the plurality of second mounting holes 17 provided on the surface of the locking block is provided with the roller 11, and the roller is mounted in a manner perpendicular to the surface of the locking block. When the wire is clamped, the roller can be in low-friction contact with the wire to realize linear rolling of the device, which not only ensures the fixation of the wire but also effectively prevents the wire insulation layer from being damaged.

[0038] In order to further improve the intelligent level of stripping operation, the surface of the first locking block 9 is provided with an infrared sensor 8, and the infrared emitter and the infrared receiver are fixed on the first locking block 9. The infrared sensor 8 distinguishes the wire sheath and the core by detecting the change of the reflected infrared wavelength of different media. When the first locking block 9 and the second locking block 10 clamp the wire and move along the wire to the core position, the infrared sensor 8 detects the change of the reflection characteristics of the core material, thereby triggering the secondary clamping function of the device, further strengthening the fixation of the core, and preventing the core from being scattered or broken due to torsion.

[0039] The driving assembly 5 provides the rotary power of the double-threaded screw rod 12, which can be directly driven by a motor or driven by a motor in cooperation with a gear transmission. Preferably, the motor driving mode in cooperation with the gear transmission is adopted, because the gear transmission can effectively amplify the torque output by the motor, ensure the stability of the locking block when clamping thicker wires or bearing larger loads, and at the same time reduce the load problem that the motor may generate due to direct driving.

[0040] The design and implementation of the device effectively solve a series of problems in the prior art. Through the clamping function of the first locking block 9 and the second locking block 10 in combination with the low-friction movement of the roller 11, the device can stably fix the wire during stripping operation, not only avoiding the wire distortion caused by torsion during the stripping process, but also protecting the insulation layer on the surface of the wire from additional damage, thereby prolonging the service life of the wire. The infrared sensor 8 in the device can accurately detect the difference in reflection characteristics between the wire sheath and the core through the cooperation of the infrared emitter and the infrared receiver. When the locking block clamps the wire and moves to the core position, the sensor detects in time and triggers the secondary clamping function, so that the wire core is more stably fixed, effectively avoiding the problem of scattered or broken caused by loose core, and providing higher safety and reliability for subsequent operation.

[0041] In addition, the double-threaded screw rod 12 and the driving assembly 5 adopted by the device realize automatic driving and precise control, reduce the cumbersome operation of installing additional locking rod devices in traditional strippers, not only reduce the labor intensity of the operator, but also greatly improve the efficiency of stripping operation. Combined with the low-friction design and intelligent control of the roller 11, the device can realize stable and efficient stripping operation on wires of different specifications, thereby adapting to the needs of different scenes.

[0042] Through this design, the working performance of the wire stripper is significantly improved, not only effectively solving the problems of wire distortion, core scattering and breaking, but also simplifying the operation process and reducing labor costs, improving the efficiency of operation while ensuring the safety of stripping operation and the integrity of the wire. The high efficiency, intelligence and reliability of the device provide important technical support for live-line work of overhead wires in the power system, and have wide practical value and application prospect.

[0043] In the embodiment, the driving assembly 5 comprises a driving motor 51, the driving motor 51 is installed on the surface of the mounting seat 4, the output end of the driving motor 51 is installed with a driving gear 52, one end of the double-threaded screw rod 12 is installed with a transmission gear 53, and the transmission gear 53 is in meshing connection with the driving gear 52.

[0044] After the driving motor 51 is started, the output end drives the driving gear 52 to rotate, and the driving gear 52 drives the double-threaded screw rod 12 through the meshing transmission of the transmission gear 53, so that the double-threaded screw rod 12 realizes stable rotation.

[0045] The rotation of the double-threaded screw rod 12 drives the first locking block 9 and the second locking block 10 engaged therewith to move synchronously in a straight line. When the driving motor 51 rotates forward, the first locking block 9 and the second locking block 10 move towards each other under the guidance of the guide rod 13, thereby clamping the wire; when the driving motor 51 reverses, the first locking block 9 and the second locking block 10 move away from each other, thereby releasing the wire. In this way, the device can realize automatic clamping and releasing operation of the wire, cooperate with the low friction characteristic of the roller 11, so that the device moves stably on the wire, while reducing the damage to the surface of the wire.

[0046] This working mode not only ensures the accurate movement and clamping force of the locking block, but also ensures that the driving power of the driving motor 51 can fully meet the clamping needs of wires of different specifications through the torque increasing effect of gear transmission, especially in the scene of thicker wires or high load, which shows excellent stability and reliability. Through this design, the device can efficiently and safely complete the fixing and peeling of the wire, significantly improving the work efficiency and wire protection effect.

[0047] In the embodiment, the surface of the mounting seat 4 is installed with a photoelectric sensor 6, and the surface of the first locking block 9 is provided with a locking trigger block 7, which corresponds to the position of the photoelectric sensor 6.

[0048] When the driving assembly 5 is started and moves the first locking block 9 and the second locking block 10 through the double-threaded screw rod 12, the locking trigger block 7 on the first locking block 9 will gradually approach the photoelectric sensor 6 with the movement of the locking block. When the locking trigger block 7 moves to the preset position and triggers the photoelectric sensor 6, the photoelectric sensor 6 will send a feedback signal to control the driving assembly 5 to stop running, so as to ensure that the first locking block 9 and the second locking block 10 are in the predetermined locking state, avoiding excessive loosening.

[0049] Through this design, the cooperation of the photoelectric sensor 6 and the locking trigger block 7 realizes accurate detection and control of the movement position of the first locking block 9 and the second locking block 10, enabling the device to dynamically adjust the position of the locking blocks according to the diameter and state of the wire. During clamping, when the wire reaches a stable clamping state, the photoelectric sensor 6 can send a signal in time to stop the driving assembly 5, avoiding damage to the surface or internal structure of the wire due to excessive clamping; when releasing the wire, the device can also detect the retreat position of the locking blocks to ensure that the wire can be released smoothly without being hindered.

[0050] This design not only improves the operation accuracy of the device in stripping operations, but also enhances the adaptability to different specifications of wires, effectively reducing the risk of wire damage caused by manual judgment or mechanical overload, and improving the safety and intelligent level of the equipment. Through the cooperation of the photoelectric sensor 6 and the locking trigger block 7, the automatic control function of the device is further improved, providing reliable protection for efficient and safe stripping operations.

[0051] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
