Description

Technical Field

[0001] The invention relates to the technical field of wire strippers, in particular to a screw-in type wire stripper with a wire locking function. Background Art

[0002] At present, the wire stripper technology is widely used in the installation, repair and maintenance of overhead wires in power systems. It is used to strip the outer insulation layer of the wire during live work or routine operation to expose the wire core for subsequent operations. In the prior art, wire strippers include manual, semi-automatic and automatic types. Among them, automatic wire strippers are widely used due to their high efficiency and ease of operation. For example, patent CN112510591B discloses a wire stripping device and a control method thereof. The technology realizes the wire stripping operation through a screw-in mechanism, thereby improving the stripping efficiency; patent CN111769485A provides a bearing-supported rotary unit and an automatic stripper for insulated overhead wires, which improves the stripping accuracy and running stability by optimizing the device structure. However, the existing automatic wire strippers usually rely on the friction of the clamping block to fix the wire, and the wire is easily damaged by torque during operation, especially when dealing with thinner wires, the risk is more obvious.

[0003] In the existing automatic strippers, the stripping torque generally causes the wire to twist or the wire core to become scattered during the stripping operation. This is especially true when stripping wires with a smaller cross-sectional area, which can easily damage or even break the wire core. These problems usually require the installation of additional locking rods or the use of other fixing devices to limit the displacement and deformation of the wire, which not only increases the complexity of the operation but also reduces work efficiency. In addition, the existing strippers are not sufficiently automated and cannot intelligently sense the position changes between the outer sheath and the core of the wire. They may not be able to provide adequate protection when stripping to the core, resulting in reduced reliability of the wire. Summary of the invention

[0004] The purpose of the embodiment of the present invention is to provide a screw-in wire stripper with a wire locking function, aiming to solve the technical problems mentioned in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A screw-in wire stripper with a wire locking function comprises a wire stripper, wherein a support portion is arranged on the surface of the wire stripper, a support arm is connected to the surface of the support portion, and an end of the support arm away from the support portion is connected to a mounting seat;

[0008] A driving assembly is disposed on the surface of the mounting seat, and the driving assembly is used to drive the double-threaded lead screw to rotate;

[0009] An infrared sensor is installed on the surface of the first locking block.

[0010] Furthermore, a rolling bearing is installed on the side of the mounting seat, and the double-threaded lead screw is rotatably mounted on the mounting seat via the rolling bearing.

[0011] Furthermore, the double-threaded lead screw is meshedly connected to the inside of a transmission nut installed on the first locking block and the second locking block, and the guide rod passes through the inside of a guide through hole opened on the surface of the first locking block and the second locking block.

[0012] Furthermore, the first locking block and the second locking block are both V-shaped structures, and the V-groove surfaces of the first locking block and the second locking block are arranged opposite to each other and correspond to each other.

[0013] Furthermore, the drive assembly includes a drive motor, and the drive motor is installed on the surface of the mounting seat, a driving gear is installed at the output end of the drive motor, a transmission gear is installed at one end of the double-threaded lead screw, and the transmission gear is meshed and connected with the driving gear.

[0015] Furthermore, the roller is installed in a manner perpendicular to the surfaces of the first locking block and the second locking block.

[0016] The invention provides a screw-in wire stripper with a wire locking function, which has the following beneficial effects:

[0017] This device achieves a stable fixation of the wire through the clamping function of the clamping block combined with the low-friction movement of the roller, effectively preventing the wire from twisting and deforming due to torque during the stripping operation, and protecting the wire insulation layer from damage, thereby extending the service life of the wire. The infrared sensor detects the difference in reflection characteristics between the outer skin and the wire core, and triggers the secondary clamping function when the locking block moves to the wire core position, further fixing the wire core to avoid loose strands or breakage caused by looseness, significantly improving the safety and reliability of the operation.

[0018] The device uses a double-threaded screw and drive assembly to achieve automatic drive and precise control, eliminating the tedious operation of installing an additional locking rod in a traditional stripper, reducing labor intensity while improving the efficiency of the stripping operation. Combined with the low-friction design and intelligent control of the roller, the device can adapt to wires of different specifications and achieve stable and efficient stripping operations.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

The above technical features belong to mature prior art, and those skilled in the art can easily implement them based on the existing technical solutions, and can make corresponding adjustments and optimizations according to actual needs. The wire stripper 1 described in the present invention can refer to the technical contents disclosed in the 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 portion 2 , and an end of the support arm 3 away from the support portion 2 is connected to a mounting seat 4 .

[0030] A double-threaded lead screw 12 is rotatably mounted inside the mounting seat 4, a rolling bearing 14 is mounted on the side of the mounting seat 4, and the double-threaded lead screw 12 is rotatably mounted on the mounting seat 4 through the rolling bearing 14. Preferably, two rolling bearings 14 are provided and distributed on the two side surfaces of the mounting seat 4.

[0031] A guide rod 13 is connected to the inside of the mounting seat 4, and the first locking block 9 and the second locking block 10 are slidably connected to both sides of the surface of the guide rod 13. 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 relatively arranged and correspond to each other.

[0032] The surfaces of the first locking block 9 and the second locking block 10 are both provided with a first mounting hole 15 and a guide through hole 16, and a transmission nut is installed inside the first mounting hole 15, the double-threaded lead screw 12 is meshedly connected to the inside of the transmission nut installed on the first locking block 9 and the second locking block 10, and the guide rod 13 passes through the guide through hole 16 opened on the surfaces of the first locking block 9 and the second locking block 10.

[0033] The surfaces of the first locking block 9 and the second locking block 10 are both provided with a plurality of second mounting holes 17, and the rollers 11 are rotatably mounted inside the second mounting holes 17. The rollers 11 are mounted perpendicular to the surfaces of the first locking block 9 and the second locking block 10.

[0034] A driving assembly 5 is disposed on the surface of the mounting seat 4 , and the driving assembly 5 is used to drive the double-threaded lead screw 12 to rotate.

[0035] An infrared sensor 8 is installed on the surface of the first locking block 9 .

[0036] In one embodiment of the present invention, the present invention provides a screw-in wire stripper with a wire locking function, which mainly includes a screw-in wire stripper 1. The wire stripper 1 is hung on the wire and can automatically complete the screw-in stripping operation along the wire to strip the wire insulation layer and expose the wire core 18. A support portion 2 is provided on the surface of the stripper 1. The support portion 2 is connected to the mounting seat 4 through a support arm 3. The mounting seat 4 is the core structure of the entire locking device and is used to carry functional components such as a double-threaded lead screw 12, a guide rod 13, and a first locking block 9, a second locking block 10, etc. The double-threaded lead screw 12 is rotatably installed inside the mounting seat 4, and low-friction rotation is achieved through a rolling bearing 14, thereby improving the operating efficiency of the locking assembly. The guide rod 13 passes through the mounting seat 4 and is slidably connected to the guide through holes 16 of the first locking block 9 and the second locking block 10, providing precise guidance for the linear movement of the locking blocks.

[0037] The first locking block 9 and the second locking block 10 are both V-shaped structures, and their V-groove surfaces are arranged relative to each other to form a stable wire clamping area. The double-threaded screw 12 is meshed and connected with the transmission nut on the surface of the locking block. Under the action of the driving assembly 5, the double-threaded screw 12 rotates, driving the first locking block 9 and the second locking block 10 to move toward or away from each other along the guide rod 13. When the locking blocks move toward each other, they can firmly clamp the wire; when they move away from each other, they release the wire to complete the operation. Rollers 11 are installed inside the several second mounting holes 17 arranged on the surface of the locking block. The rollers are installed in a manner perpendicular to the surface of the locking block. When clamping the wire, the rollers can contact the wire with low friction to achieve linear rolling of the device, which not only ensures the fixation of the wire but also effectively prevents the insulation layer of the wire from being damaged.

[0038] In order to further improve the intelligent level of the stripping operation, an infrared sensor 8 is installed on the surface of the first locking block 9. The infrared emitter and the infrared receiver are fixed to the first locking block 9. The outer skin and the core of the wire are distinguished by detecting the change of infrared wavelength reflected by 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 reflective 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 torque.

[0039] The driving assembly 5 provides the rotational power of the double-threaded lead screw 12, and can be driven directly by a motor or driven by a motor in combination with a gear transmission. It is preferred to use a motor driven in combination with a gear transmission, because the gear transmission can effectively amplify the torque output by the motor, ensure the stability of the locking block when clamping a thicker wire or bearing a larger load, and reduce the load problem that may be caused by direct driving of the motor.

[0040] The design and implementation of this device effectively solves a series of problems in the prior art. Through the clamping function of the first locking block 9 and the second locking block 10 combined with the low-friction movement of the roller 11, the device can firmly fix the wire during the stripping operation, which not only avoids the twisting and deformation of the wire due to the torque during the screw-in stripping process, but also protects the insulation layer on the surface of the wire from additional damage, thereby extending the service life of the wire. The infrared sensor 8 in the device can accurately detect the difference in reflection characteristics between the outer sheath and the core of the wire through the cooperation of the infrared emitter and the infrared receiver. When the locking block clamps the wire to the core position, the sensor promptly detects and triggers the secondary clamping function, so that the core of the wire is more firmly fixed, effectively avoiding the problem of loose strands or breakage caused by loose cores, and providing higher safety and reliability for subsequent operations.

[0041] In addition, the double-threaded lead screw 12 and the drive assembly 5 used in the device realize automatic drive and precise control, reducing the cumbersome operation of installing an additional locking rod device in the traditional stripper, which not only reduces the labor intensity of the operator, but also greatly improves the efficiency of the stripping operation. Combined with the low-friction design and intelligent control of the roller 11, the device can achieve stable and efficient stripping operations on wires of different specifications, thereby adapting to the needs of different scenarios.

[0042] Through this design, the present invention significantly improves the working performance of the wire stripper, effectively solves the problems of wire distortion and wire core breakage, simplifies the operation process, reduces labor costs, and improves the work efficiency while ensuring the safety of the stripping operation and the integrity of the wire. The efficiency, intelligence and reliability of the device provide important technical support for live operations on overhead wires in power systems, and have broad practical value and application prospects.

[0043] In this embodiment, the drive assembly 5 includes a drive motor 51, and the drive motor 51 is installed on the surface of the mounting base 4, a driving gear 52 is installed at the output end of the drive motor 51, a transmission gear 53 is installed at one end of the double-threaded screw 12, and the transmission gear 53 is meshed and connected with the driving gear 52.

[0044] After the driving motor 51 is started, its output end drives the driving gear 52 to rotate, and the driving gear 52 transmits the rotational power to the double-threaded lead screw 12 through meshing transmission with the transmission gear 53, so that the double-threaded lead screw 12 can achieve stable rotation.

[0045] The rotation of the double-threaded lead screw 12 drives the first locking block 9 and the second locking block 10 meshing therewith to move linearly in sync. When the drive motor 51 rotates forward, the first locking block 9 and the second locking block 10 move toward each other under the guidance of the guide rod 13, thereby clamping the wire; when the drive motor 51 rotates reversely, the first locking block 9 and the second locking block 10 move backwards to release the wire. In this way, the device can realize automatic clamping and releasing operations on the wire, and with the low friction characteristics of the roller 11, the device can move stably on the wire while reducing damage to the wire surface.

[0046] This working mode not only ensures the precise movement and clamping force of the locking block, but also ensures that the power of the drive motor 51 can fully meet the clamping requirements of wires of different specifications through the torque-increasing effect of the gear transmission, especially showing excellent stability and reliability in thicker wires or high-load scenarios. Through this design, the device can efficiently and safely complete the fixing and stripping operations of the wires, significantly improving work efficiency and wire protection effects.

[0047] In this embodiment, a photoelectric sensor 6 is installed on the surface of the mounting seat 4 , and a locking trigger block 7 is provided on the surface of the first locking block 9 . The positions of the locking trigger block 7 and the photoelectric sensor 6 correspond to each other.

[0048] When the driving assembly 5 is started and drives the first locking block 9 and the second locking block 10 to move through the double-threaded lead screw 12, the locking trigger block 7 on the first locking block 9 will gradually approach the photoelectric sensor 6 as the locking block moves. 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, ensuring that the first locking block 9 and the second locking block 10 are in a predetermined locking state to avoid excessive loosening.

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

[0050] This design not only improves the operating accuracy of the device in the stripping operation, but also enhances the adaptability to wires of different specifications, effectively reduces the risk of wire damage caused by manual judgment or mechanical overload, and improves the safety and intelligence 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 guarantee for efficient and safe stripping operations.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
