The existing insulation strippers are divided into electric and manual ones. Electric insulation strippers are expensive, large in size and cannot handle the end of the wire. They can only perform insulation stripping on horizontally stressed wires. Manual insulation strippers are divided into rotary and straight-cut types. The rotary type requires repeated adjustment of the cutting depth of the blade and the end treatment is still not ideal. The straight-cut insulation stripper has a simple structure, is cheap, and is easy to operate, but it is time-consuming and labor-intensive, and requires a high level of skill from the operator, and it is easy to damage the wire during operation. Summary of the invention

[0004] The technical solution adopted by the present invention is:

[0009] Furthermore, a lifting motor is installed at the bottom of the connecting shell, and a lifting transmission component for controlling the lifting of the blade is installed inside the connecting shell.

[0011] Furthermore, a polygonal vertical inner cavity is arranged inside the connecting shell, and the sliding sleeve is a polygonal column structure; the vertical inner cavity of the connecting shell forms a rotation restriction on the sliding sleeve.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0032] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0033] Embodiment 1:

[0034] like Figure 1 As shown, a wire end processing device provided by an embodiment of the present invention includes a C-shaped bracket 4; a connecting shell 2 and a stopper 8 installed at both ends of the bracket 4; a blade 3 rotatably installed at the upper end of the connecting shell 2 and located in the C-shaped opening of the bracket 4; and a plurality of travel wheels 5 rotatably installed at the stopper 8 and arranged opposite to the blade 3. A motor box 6 is fixedly connected to one side of the stopper 8, and the motor box 6 cooperates with the stopper 8 to form a concave structure to cooperate with the coaxial arrangement of the plurality of travel wheels 5. A transmission assembly is provided in the motor box 6 to form a transmission connection between the travel wheel 5 and the travel drive motor. As shown Figure 1 As shown, a battery box 7 is installed at one end of the bracket 4, and the battery box 7 is equipped with a battery for powering the walking drive motor.

[0035] Since the wires in this embodiment are insulated wires used in 10kV distribution networks, Figure 1 and 2 As shown, the number of the running wheels 5 is two groups, and the two groups of running wheels 5 are coaxially arranged and rotatably installed between the motor box 6 and the stopper 8. Further, the rotatable installation of the running wheels 5 in this embodiment is achieved by the following methods; as shown in 1 and Figure 2 As shown, bearings 9 are installed on the outer wall of one side of the stopper 8 and on the two side walls of the motor box 6. One end of the axle 13 of the walking wheel 5 is rotatably installed on the stopper 8 through the bearing 9, and the other end extends into the motor box 6 and is installed through two bearings 9.

[0036] Furthermore, the structure of the transmission assembly for driving the two sets of running wheels 5 to rotate in this embodiment is as follows: Figure 1 and 2As shown, the transmission assembly in this embodiment includes a driving gear 14 and a driven gear 12; wherein, the travel drive motor is fixedly mounted on the outer wall of the motor box 6, and the travel drive motor is not shown in the figure. The output shaft 1 of the travel drive motor passes through the motor box 6 and extends to the inside thereof, and the driving gear 14 is fixedly mounted on the output shaft 1; a bearing is installed at the contact point between the output shaft 1 and the box wall of the motor box 6. The driven gear 12 is located at the front and rear sides below the driving gear 14, and the number thereof is two, which matches the number of the travel wheels 5. The two driven gears 12 are fixedly mounted on the wheel axle 13 of the travel wheel 5, and are respectively meshed with the driving gear 14.

[0037] The working principle of the wire end processing device is as follows:

[0038] like Figure 4 As shown, when in use, first hold the middle section of the bracket 4 with your hand, and install the wire end processing device from one end of the wire to the wire; then start the travel drive motor, and the travel drive motor drives the two sets of travel wheels 5 to rotate in the same direction through the output shaft 1, the driving gear 14 and the driven gear 12, so that the wire end processing device moves along the wire; while walking, the blade 3 cuts the insulating outer layer of the wire. After the insulating outer layer of the wire is cut, the operator can remove the insulating outer layer and carry out the further new line connection process.

[0039] The conductor end processing device is designed with a combination of blades and travel wheels, so that it can cut the insulation layer of the conductor while walking, thereby improving the working efficiency. Traditional methods may require additional manpower and tools, while this device can realize an automated cutting process and reduce the complexity of manual operation. The design of two sets of travel wheels, combined with motor drive, ensures the stability and flexibility of walking on the conductor. The coaxial arrangement of the travel wheels and the combination of the transmission components enable the device to move smoothly along the conductor, reducing the risk of failure caused by friction or instability. The blade is controlled by a mechanical transmission system, and the operator can maintain a safe distance during use, reducing the risk of accidental injury caused by direct contact with the blade. At the same time, the design of the blade enables the cutting to be precise and thorough, avoiding the safety hazards caused by incomplete cutting. The design for the insulated conductor of the 10kV distribution network makes it show good adaptability in such specific environments and can meet the maintenance requirements of the high-voltage distribution network. Its structural design also provides the possibility of adjustability for the processing of conductors of different specifications. It is easy to operate and maintain; the easy-to-replace design of the motor, blade and travel wheel simplifies the daily maintenance of the equipment, thereby improving the efficiency and sustainability of the equipment. The automation feature of the device reduces manual operation time and labor costs. At the same time, through efficient cutting and processing, the operation time is shortened, thereby reducing the overall construction cost.

[0040] Example 2

[0041] On the basis of Example 1, in order to meet the requirements of cutting different wire thicknesses and different insulation layer thicknesses, as shown in FIG. Figure 1 As shown, in this embodiment, a lifting motor 15 for controlling the lifting of the blade 3 is installed at the bottom of the connecting shell 2; Figure 2 As shown, in this embodiment, a lifting transmission assembly for controlling the lifting of the blade 3 is installed inside the connecting shell 2.

[0042] Specifically, Figure 2 and Figure 3 As shown, a polygonal vertical inner cavity is arranged inside the connecting shell 2, and a sliding sleeve 11 is slidably installed inside the vertical inner cavity. The sliding sleeve 11 is a polygonal column structure, and the blade 3 is rotatably installed on the upper end thereof; the interior of the sliding sleeve 11 is hollow, and a screw rod 10 is inserted inside the sliding sleeve 11. The screw rod 10 is threadedly connected inside the fixed block 11, and the lower end of the screw rod 10 is fixedly connected to the output end of the lifting motor 15.

[0043] The present embodiment adopts a lifting transmission assembly consisting of a sleeve 11 and a screw rod 10. When the lifting motor 15 drives the screw rod 10 to rotate, the sleeve 11 is threadedly connected to the screw rod 10, and the sleeve 11 adopts a rectangular column structure, which is restricted by the rotation of the vertical inner cavity of the connecting shell 2. Therefore, in the process of the lifting motor 15 driving the screw rod 10 to rotate, the sleeve 11 drives the blade 3 to perform a lifting movement relative to the connecting shell 2, so as to adjust the position of the blade 3 to meet the requirements of cutting different wire thicknesses and different insulation layer thicknesses.

[0044] The working principle of the wire end processing device is as follows:

[0045] like Figure 3 and 4 As shown, when in use, first hold the middle section of the bracket 4 with your hand, and install the wire end processing device from one end of the wire to the wire; then start the lifting motor 15, and adjust it to the required cutting position of the wire insulation layer thickness through the sliding sleeve 11 and the screw rod 10; then start the travel drive motor, and the travel drive motor drives the two sets of travel wheels 5 to rotate in the same direction through the output shaft 1, the driving gear 14 and the driven gear 12, so that the wire end processing device moves along the wire; while walking, the blade 3 cuts the insulation outer layer of the wire to a required thickness with a fixed depth. After the insulation outer layer of the wire is cut, the operator can remove the insulation outer layer and carry out further new line connection process.

[0046] It should be noted that the lifting motor 15 in this embodiment is routed to the battery box 7 through the internal wiring of the bracket 4, and the battery in the battery box 7 is used to power the travel drive motor and the lifting motor 15 at the same time to meet the operation requirements. In addition, the lifting transmission assembly and the lifting motor 15 in this embodiment can also be replaced by a small electric cylinder.

[0047] The wire end processing device can adapt to the cutting requirements of different wire thicknesses and insulation layer thicknesses. By adjusting the configuration of the sliding sleeve and the lead screw, the blade position can be flexibly adjusted to meet the diverse wire processing requirements. Through the coordinated work of the lifting motor and the transmission assembly, the lifting and lowering movement of the blade can be precisely controlled, which ensures the accuracy of the cutting depth and avoids wire damage caused by improper cutting. The operator only needs to simply hold the bracket to easily install the device on one end of the wire, and then adjust the blade position through the motor. The operation process is simple and improves work efficiency. During the movement of the device, the fixed depth cutting of the insulation layer by the blade ensures the continuity and consistency of the cutting work, ensures the cutting quality, and helps the smooth progress of subsequent operations. The battery box provides power to the lifting motor and the travel drive motor, realizing integrated power supply management and ensuring the sustainable operation of the equipment under different working conditions. The lifting transmission assembly and the lifting motor are designed to be replaceable, and a small electric cylinder can be used as an alternative, so as to achieve component optimization and updating without affecting the overall performance.

[0048] Example 3

[0049] Based on Example 2, this example further implements automatic control, such as Figure 1 As shown, in this embodiment, an automatic sensing device 16 is installed on the outer wall of the blade 3, and a circuit board is installed in the battery box 7. The circuit board is wirelessly connected to the automatic sensing device 16. The position of the blade 3 is accurately and automatically adjusted by the automatic sensing device 16 in cooperation with the circuit board to avoid damage to the wire due to inaccurate manual control.

[0050] Among them, the automatic sensing device 16 is specifically a UT20-150-AUM4 / AIM4 acoustic wave sensor; the energy in the form of acoustic waves is emitted by the transmitting end of the automatic sensing device, and when the receiving end of the automatic sensing device receives the energy, it is converted into an electrical signal, which is then processed and analyzed by the circuit board, thereby realizing the detection, positioning, and tracking of the target object, and realizing the fine-tuning of the blade 3 according to the position of the wire.

[0051] The circuit board in this embodiment specifically includes the following circuits:

[0052] Motor drive description:

[0053] like Figure 5As shown, the circuit board is provided with two motor drive circuits for cooperating with the walking drive motor and the lifting motor 15. The motor drive circuit includes a logic input control Hbridge driver, which is composed of four n-channel MOSFETs. The input can control the motor speed and steering through pulse width modulation PWM. By using the current decay mode selection and setting both inputs to low, it enters a low-power sleep mode.

[0054] Motor working current detection instructions:

[0055] like Figure 6 As shown, the circuit board is also provided with two motor working current detection circuits, which respectively detect the voltage of the motor driver rear resistors R1 and R4; during the operation of the walking drive motor and the lifting motor 15, the current will return to the negative electrode of the battery through ISEN, and the voltage on the two resistors can be detected to obtain the motor working current, thereby controlling the cutting depth and motor stall judgment.

[0056] Power supply description:

[0057] In this embodiment, a 12V lithium battery is installed in the battery box 7, and the main control power supply is 3.3V; at the same time, the circuit board is provided with a power supply control circuit to match the lithium battery. Figure 7 As shown, it is mainly a buck circuit. U7 in the power supply control circuit is a 40V / 5A buck regulator with an integrated high-side MOSFET; the device has a wide input range of 4V to 40V, a quiescent current of 40uA in sleep mode, and an ultra-low current of 1μA in shutdown mode. Its output voltage is calculated as: (R17 / R21+1)*0.75.

[0058] Main control part description:

[0059] The circuit board also has a main control circuit; the main control circuit is as follows Figure 8 As shown in the figure, the main control circuit includes an MCU, which outputs PWM pulse width modulation and a driver to control the motor, and detects the working current of the motor through ADC analog-to-digital conversion. In addition, the main control circuit also includes a power supply, a clock, a reset circuit, and necessary input and output I / O interfaces.

[0060] Remote Control Instructions:

[0061] The circuit board is also provided with a remote control circuit. Fig. 9 As shown in the figure, the remote control circuit is a serial wireless transparent transmission module that receives control signals from the remote control and forwards them to the MCU through the serial port to control the motor. Fig.10As shown, its core function is to use the external terminal of the MCU to detect the pressing or releasing of a key, thereby sending the key value signal of the pressed key to the receiving terminal.

[0062] The wire end processing device realizes precise adjustment of the position of the blade 3 through wireless connection with the circuit board through the automatic sensing device 16 (UT20-150-AUM4 / AIM4 acoustic sensor). The device uses acoustic wave signals for detection, positioning and tracking to ensure that the blade can be fine-tuned according to the position of the wire, greatly reducing the errors that may occur during manual operation and reducing the risk of wire damage. The design of the device makes the operation fully automated. Combined with the synergy of the travel drive motor and the lifting motor, the lifting and lowering of the blade can be automatically adjusted according to the thickness of different wires and the thickness of the insulation layer. This highly automated control reduces the need for manual intervention and improves work efficiency. The circuit board is provided with a working current detection circuit, which monitors the voltage of the rear resistor of the motor driver and provides real-time feedback on the working status of the motor. This function not only helps to accurately control the cutting depth of the blade, but also can timely determine whether the motor is blocked, avoid equipment damage, and improve the reliability of the equipment. The step-down circuit of the power supply part adopts an efficient MOSFET regulator with extremely low quiescent current in sleep and shutdown modes, which enhances the battery life of the device. This design ensures long-term stable operation and adapts to the use characteristics of 12V lithium batteries. Through the design of the remote control circuit, operators can conveniently control the equipment remotely. The MCU receives and processes the instructions from the remote control signal in real time, ensuring the flexibility and convenience of operation and adapting to different operation requirements. Due to the introduction of automation and precise control, this device greatly reduces the labor intensity of operators, reduces the physical fatigue caused by manual operation, and improves the safety and comfort of the working environment.

[0063] In summary, this embodiment not only improves the accuracy and efficiency of wire end processing through innovative circuit design and automated control technology, but also effectively reduces the operating risks and labor intensity of operators, and has significant technical advantages and practical value.

[0064] In summary, in combination with Example 1, Example 2 and Example 3, the wire end processing device drives the gear to rotate through the travel drive motor so that the travel wheel 5 rotates so that the device can move along the wire, and controls the lifting and lowering of the blade 3 through the lifting motor 15 so that the device can adapt to the requirements of cutting different wire thicknesses and different insulation layer thicknesses. In addition, the position of the blade 3 is accurately and automatically adjusted by the automatic sensing device 16 in conjunction with the circuit board to avoid damage to the wire due to inaccurate manual control, realize automatic control, facilitate the operation of the operator, improve work efficiency, and the device uses full-automatic operation to reduce labor intensity.
