[0030] The present invention has made technical innovations for clamping pliers in the field of power maintenance, aiming to achieve more precise clamping force control and automated wire retraction and release functions to improve the efficiency and convenience of power maintenance work. The support frame 21 is composed of an equipment base frame 11 and a transmission platform 12. The equipment base frame 11 is made of high-strength materials as the supporting structure of the entire device to ensure the stability of the overall structure. The transmission platform 12 is embedded with a precise guide rail system to guide the sliding of the secondary adjustment frame 22 and achieve precise position adjustment through motor drive. An intelligent control module is added to make the movement of the pusher 14 and the azimuth adjustment seat 18 more precise. The pusher 14 is driven by a servo motor, which can achieve fast and smooth advancement. At the same time, it is equipped with an encoder to monitor the position information in real time. The azimuth adjustment seat 18 contacts the guide rail of the transmission platform 12 through a precise roller, ensuring smooth and precise azimuth adjustment. The azimuth detector 13 can use a non-contact sensor, such as a laser rangefinder or an infrared sensor, to feedback the position information of the azimuth adjustment seat 18 in real time to ensure the accuracy of the adjustment.

[0031] The positioning assembly 19 is designed as an adjustable clamping block structure, which can adapt to wires of different diameters. The clamp fixing member 10 is made of high-strength alloy material to ensure that the wire will not be damaged during the clamping process. The positioning assembly 19 is used to position the wire in the front and back directions, and the clamp fixing member 10 clamps the wire from the left and right directions. By optimizing the design of the positioning assembly 19 and the clamp fixing member 10, the present invention realizes accurate positioning and stable clamping of the wire in the front and back directions and the left and right directions, effectively avoiding wire damage or safety accidents caused by inaccurate positioning or unstable clamping.

[0032] In addition to the original fixing function, the clamp body mounting seat 17 also integrates the driving unit of the clamping force controller 24, which is connected to the positioning component 19 through a precise gear transmission system or a direct drive mechanism to achieve precise control of the clamping force of the clamp fixing part 10. The clamping force controller 24 adopts a closed-loop control system and integrates a pressure sensor and a microprocessor. The pressure sensor monitors the pressure value of the pressure-bearing end of the positioning component 19 in real time. The microprocessor calculates and outputs a control signal through an algorithm according to the preset clamping force range, adjusts the output power of the driving unit, and thus achieves precise adjustment of the clamping force of the clamp fixing part 10.

[0033] In this embodiment, the transmission platform 12 on the support frame 21 works with the push machine 14, the push seat 15 and the azimuth adjustment seat 18 of the secondary adjustment frame 22, and realizes precise positioning through sliding installation, and quickly responds to the operation command. The azimuth detector 13 monitors the position of the azimuth adjustment seat 18 in real time to ensure that the clamp body assembly 23 accurately reaches the operation point. The clamp fixing member 10 in the clamp body assembly 23 and the positioning assembly 19 are closely matched to ensure stable clamping of the wire and prevent the wire from slipping or being damaged during the operation. The clamping force controller 24 monitors and adjusts the clamping and crimping force in real time to avoid wire damage or personal injury caused by excessive force. The positioning assembly 19 on the clamp body mounting seat 17 adopts a high-precision design, which can realize precise positioning of the wire. The synergistic effect of the clamp fixing member 10 and the positioning assembly 19 ensures that the clamping is stable and the crimping quality meets the standard requirements. The precise control of the clamping force controller 24 improves the stability and reliability during the operation. The overall implementation structure of the present invention can cooperate with the automatic control system. The automatic control system of the pliers integrates intelligent components such as sensors and microprocessors, and can also be designed to communicate with a remote monitoring center to achieve remote monitoring and operation, providing strong support for the intelligent development of the field of power maintenance.

[0034] For example 2, please refer to Figure 1 , Figure 2 and Figure 3 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the support frame 21 is designed as follows: The transmission platform 12 includes a sliding rail 41 and a sliding base plate 45 mounted on the sliding rail 41. The sliding rail 41 is installed in the frame shell of the equipment base frame 11. The azimuth adjustment seat 18 includes a displacement base 31 and a mounting bar 32 mounted on the displacement base 31. The displacement base 31 is slidably mounted on the sliding rail 41. The mounting bar 32 is mounted on the table of the sliding base plate 45. An inner threading screw 44 is arranged in the sliding rail 41. A transmission screw sleeve 33 is arranged at the bottom of the displacement base 31. The inner threading screw 44 is installed in the screw hole of the transmission screw sleeve 33. A driving seat 42 is installed at the frame end of the sliding rail 41. A driving motor 43 for driving the sliding rail 41 is installed on the driving seat 42.

[0035] The transmission platform 12 is mainly composed of a sliding rail 41 and a sliding base plate 45. The sliding rail 41 is firmly mounted inside the frame shell of the equipment base frame 11, providing a stable and precise moving path for the displacement base 31. The sliding base plate 45 is mounted above the sliding rail 41 to form a stable working surface for the installation bar 32 and the secondary adjustment frame 22 thereon. The azimuth adjustment seat 18 is an important component connecting the secondary adjustment frame 22 and the transmission platform 12, and is composed of a displacement base 31 and a mounting bar 32. The bottom of the displacement base 31 is designed with a sliding structure that matches the sliding rail 41 to ensure that it can move smoothly on the rail. At the same time, the displacement base 31 is also equipped with a transmission screw sleeve 33, which is tightly matched with the inner screw 44 in the sliding rail 41. When the inner screw 44 rotates, the displacement base 31 is driven to move linearly along the sliding rail 41 through the principle of thread transmission.

[0036] For the specific implementation structure of the position detector 13, please refer to Figure 3 and Figure 4 , this embodiment is designed as follows: The orientation detector 13 includes a first photosensitive detector 51 and a second photosensitive detector 52 arranged on the equipment base frame 11, and the first photosensitive detector 51 and the second photosensitive detector 52 are respectively arranged at the two ends of the inner frame of the equipment base frame 11; the first photosensitive detector 51 and the second photosensitive detector 52 both include a detection sliding frame 53, a probe mounting block 54 and a photosensitive probe 55, the probe mounting block 54 is slidably mounted on the detection sliding frame 53, and the photosensitive probe 55 is fixedly mounted on the probe mounting block 54, and light-sensitive spotlights are arranged on both sides of the transmission screw sleeve 33, and the probe mounting blocks 54 on the first photosensitive detector 51 and the second photosensitive detector 52 are respectively connected to the light-sensitive spotlights on the corresponding sides by electrical signals.

[0037] The orientation detector 13 is mainly composed of a first photosensitive detector 51 and a second photosensitive detector 52, which are respectively arranged at two ends of the inner frame of the device base frame 11, and can capture its position information from both sides, with more accurate capture.

[0038] The first photosensitive detector 51 and the second photosensitive detector 52 adopt the same structure, and both include three main parts: a detection sliding frame 53, a probe mounting block 54, and a photosensitive probe 55. The photosensitive spotlights are located on both sides of the transmission screw sleeve 33 and are installed at the bottom of the installation column 32. The photosensitive spotlights are respectively connected to the probe mounting blocks 54 on the first photosensitive detector 51 and the second photosensitive detector 52 with electrical signals, and the light emitted by the photosensitive spotlights will be captured by the corresponding photosensitive probes 55 and converted into electrical signals for transmission and processing. When the secondary adjustment frame 22 moves, it will drive the displacement base 31 and the transmission screw sleeve 33 to move together. The photosensitive spotlights on both sides of the transmission screw sleeve 33 will also move accordingly, and change the relative position with the photosensitive probes 55 on the first photosensitive detector 51 and the second photosensitive detector 52. The photosensitive probe 55 will capture the changes of these light signals in real time and convert them into electrical signals for transmission. The control system will accurately calculate the current position of the secondary adjustment frame 22 and the clamp assembly 23 thereon according to the changes of these electrical signals, thereby realizing real-time monitoring and precise control of their positions. The electrical signal connection between the photosensitive detector and the light-sensitive spotlight, as well as the data transmission between them and the control system, all adopt stable and reliable communication protocols and technologies. This design ensures the stability and reliability of the entire system.

[0039] In one case of this embodiment, a fine-tuning push rod 57 for driving the probe mounting block 54 to slide is provided on the detection slide frame 53 , and a scale ruler 56 is also provided in the track of the detection slide frame 53 , and the probe mounting block 54 is mounted on the scale ruler 56 .

[0040] The detection slide frame 53 serves as a track for the probe mounting block 54, ensuring that the photosensitive probe 55 can be fine-tuned within a certain range to meet different operating requirements. The scale 56 is also a light shielding measurement tool, which is used to indicate the specific position of the probe mounting block 54 on the detection slide frame 53. This allows precise adjustment of the detection range of the photosensitive probe 55. This design not only improves the accuracy of the detection, but also enhances the adaptability and flexibility of the system.

[0041] For example 3, please refer to Figure 5 This embodiment is a further design of the above embodiment. On this basis, for the specific implementation structure of the secondary adjustment frame 22, this embodiment is designed as follows: The combination of the push seat 15 and the push machine 14 constitutes the core moving part of the secondary adjustment frame 22, and they work together to achieve precise adjustment of the clamp body assembly 23 on the wire position. The push seat 15 is mainly composed of a support seat 84 and a clamp seat mounting base plate 85. The support seat 84 is a supporting structure of the entire push seat 15. Its design is sturdy and stable, and it can withstand the clamp body assembly 23 and various forces during its operation. The clamp seat mounting base plate 85 is fixedly installed on the support seat 84, which is used to install and support the clamp body assembly 23 to ensure its stability and accuracy during operation. The push machine 14 includes a push base frame 81 and a push rail 82. The push base frame 81 is the main structure of the entire push machine 14, providing a stable support platform. The push rail 82 is cleverly arranged on the push base frame 81, and its design is precise and smooth, which is used to guide the sliding of the support seat 84. On the push base frame 81, we also set a drive assembly 83. The driving assembly 83 is a precise driving device, which realizes precise control of the sliding of the supporting seat 84 on the pushing rail 82 by connecting with the supporting seat 84. In terms of adjustment, the combination of the pushing seat 15 and the pushing machine 14 is similar to the adjustment of the transmission platform 12. Through the precise control of the driving assembly 83, we can realize the sliding of the supporting seat 84 on the pushing rail 82, thereby driving the clamp mounting base plate 85 and the clamp body assembly 23 thereon to move. This design not only improves the accuracy and efficiency of the operation, but also enhances the flexibility and adaptability of the system.

[0042] Example 4, please refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the clamp fixing member 10 and the positioning assembly 19 is designed as follows: The positioning assembly 19 includes a pusher 62 disposed on both sides of the clamp body mounting seat 17 and a fixed clamp plate 63 mounted on the pusher 62, wherein the fixed clamp plate 63 is fixedly mounted on the bottom end of the pusher 62, and a pulling rod 64 is also disposed on the pusher 62, wherein the rod body of the pulling rod 64 passes through the fixed clamp plate 63 and a pulling clamp plate 65 is mounted on the rod end. The positioning assembly 19 is used to clamp the wire in the front and rear directions, and the wire is clamped in the gap between the fixed clamp plate 63 and the pulling clamp plate 65, and a buffer spring 61 is also disposed between the fixed clamp plate 63 and the pulling clamp plate 65.

[0043] The clamping force controller 24 includes a mounting support plate 92 and a pneumatic sensor box 91 mounted on the mounting support plate 92. The mounting support plate 92 is fixed to the inner frame plate of the clamp body mounting seat 17. The mounting support plate 92 is provided with a valve body 94 and a pneumatic adjustment cylinder 95 mounted on the valve body 94. The pneumatic sensor box 91 is externally connected to a pneumatic pipeline 93. The pull rod 64 is piston-mounted in the box of the fixed clamp plate 63, and the cylinder body of the pneumatic adjustment cylinder 95 is connected to the telescopic end of the pull rod 64 through an air pipe.

[0044] The pneumatic sensor box 91 is connected to an external pneumatic pipeline 93, which is responsible for receiving and transmitting the clamping force control signal and controlling the action of the pneumatic adjustment cylinder 95. The pneumatic pipeline 93 serves as a transmission channel for the pneumatic signal, connecting the pneumatic sensor box 91 and the pneumatic adjustment cylinder 95 to ensure accurate signal transmission. The valve body 94 is installed on the mounting support 92 to control the opening and closing of the pneumatic adjustment cylinder 95, thereby achieving precise control of the movement of the pull rod 64. The pneumatic adjustment cylinder 95 is connected to the telescopic end of the pull rod 64 through an air pipe. According to the signal received by the pneumatic sensor box 91, the telescopic distance of the pull rod 64 is adjusted, thereby changing the clamping distance between the fixed clamp plate 63 and the pull clamp plate 65. When the wire needs to be clamped, the clamping force controller 24 sends a clamping signal to the pneumatic sensor box 91. After receiving the signal, the pneumatic sensor box 91 transmits the signal to the pneumatic adjustment cylinder 95 through the pneumatic pipeline 93. The pneumatic adjustment cylinder 95 adjusts the telescopic distance of the pull rod 64 according to the signal, so that the pull clamp 65 moves toward the fixed clamp 63 until the gap between the two just clamps the wire. When the wire needs to be released, the pneumatic sensor box 91 transmits the signal to the pneumatic adjustment cylinder 95 again through the pneumatic pipeline 93, and the pneumatic adjustment cylinder 95 adjusts the telescopic distance of the pull rod 64, so that the pull clamp 65 moves away from the fixed clamp 63 to release the wire. The elastic restoring force of the buffer spring 61 helps the smooth movement of the pull clamp 65 to ensure the safe release of the wire. This embodiment can accurately control the movement distance of the pull rod 64, so as to flexibly adjust the clamping distance between the fixed clamp 63 and the pull clamp 65 to meet the clamping requirements of wires of different diameters. The combination of the precisely controlled clamping force effectively avoids excessive extrusion of the wire during the clamping process and protects the integrity of the wire. The coordinated work of the pneumatic sensor box 91 and the pneumatic adjustment cylinder 95 realizes the rapid clamping and release of the wire, and improves the work efficiency of the power maintenance operation.

[0045] The clamp fixture 10 is designed to ensure that the cable is stably and accurately clamped in the left and right directions. The clamp 71 is the main structure of the clamp fixture 10, and the clamp 71 is fixedly mounted on the bottom of the clamp body mounting seat 17. The kneading block 72 is installed in an open and close manner at the clamping end of the clamp 71. When the kneading block 72 is opened, the opening and closing clamp arm 73 is also opened; when the kneading block 72 is closed, the opening and closing clamp arm 73 tightly clamps the cable. The design of the opening and closing clamp arm 73 allows the cable to remain stable during the clamping process. The clamp body clamp block 74: The clamp body clamp block 74 is installed on the opening and closing clamp arm 73 and is the part that actually contacts the cable. The clamp body clamp block 74 is usually made of wear-resistant and corrosion-resistant materials to ensure its long-term performance. A contact head 76 is provided on the inner clamp surface of the clamp body clamp block 74 for tightly fitting with the cable. Pressure sensor 75: The pressure sensor 75 is externally connected to the clamp block 74, and its sensing end is connected to the contact head 76. The pressure sensor 75 can monitor the clamping pressure of the clamp block 74 on the cable in real time and transmit the data to the control system for accurate clamping force control.

[0046] In power inspection or line maintenance operations, it is often necessary to pull or adjust the wires to the left and right directions, while ensuring that the wires are stably limited in the up and down directions. The opening and closing clamp arms 73 in the clamp fixing member 10 are designed to be both sturdy and flexible. When it is necessary to pull or adjust the wires to the left and right directions, the opening and closing clamp arms 73 can be loosened. At this time, the fixed clamp plate 63 and the pulling clamp plate 65 will also be loosened appropriately to provide sufficient space for the left and right movement of the wires. At the same time, since the fixed clamp plate 63 and the pulling clamp plate 65 limit the wires in the up and down directions, the wires will not escape the control range of the clamp body when moving left and right. The clamping force controller 24 can accurately control the movement distance of the pulling rod 64, thereby adjusting the clamping spacing between the fixed clamp plate 63 and the pulling clamp plate 65. When the fixing tightness of the wire needs to be increased, the clamping force controller 24 will drive the pulling rod 64 to move toward the fixed clamp plate 63, so that the clamping distance between the two is reduced; conversely, when the fixing tightness of the wire needs to be reduced, the clamping force controller 24 will drive the pulling rod 64 to move away from the fixed clamp plate 63, so that the clamping distance between the two is increased.

[0047] Based on the above embodiment, the present invention also discloses a method for using a power maintenance pliers structure, comprising the following steps: Step 1. Preparation: Check the equipment status. Before using the power maintenance clamp structure, first check whether the equipment base frame 11, transmission platform 12, secondary adjustment frame 22 and other components are intact, and ensure that all fasteners are correctly installed and tightened. Connect the power maintenance clamp structure to a stable power supply, and turn on the power switch of the intelligent control module to ensure that all electronic components are working properly; Step 2: Adjust the position: Start the transmission platform 12, and start the motor in the transmission platform 12 through the intelligent control module to drive the secondary adjustment frame 22 to slide to the desired position on the guide rail system. Use the encoder to monitor the position information in real time to ensure the accurate positioning of the secondary adjustment frame 22. Adjust the azimuth adjustment seat 18: Use the azimuth detector 13 to monitor the position of the azimuth adjustment seat 18 in real time, and adjust the position of its roller on the guide rail of the transmission platform 12 through the intelligent control module to achieve smooth and accurate azimuth adjustment; Step 3: Install the wires: Place the wires to be repaired in the adjustable clamping block structure of the positioning assembly 19, adjust the clamping block structure according to the diameter of the wires, and ensure that the wires are accurately positioned in the front-to-back direction; start the clamp fixture 10 to clamp the wires from the left and right directions. At the same time, the closed-loop control system of the clamping force controller 24 starts working, and the pressure sensor monitors the pressure value of the pressure-bearing end of the positioning assembly 19 in real time; Step 4, adjusting the clamping force: preset a suitable clamping force range in the microprocessor of the clamping force controller 24 to ensure that the wire will neither be damaged nor loosened during the clamping process, and adjusting the clamping force: the microprocessor calculates and outputs a control signal through an algorithm according to the pressure value monitored in real time by the pressure sensor, and adjusts the output power of the driving unit of the clamping force controller 24, thereby realizing accurate adjustment of the clamping force of the clamp fixing member 10; Step 5: Conducting power inspection: After confirming that the wire has been firmly clamped, the operator can start the power inspection operation, such as checking the wire insulation layer, connector, etc. If further inspection or maintenance of the wire is required, the servo motor of the push machine 14 can be started through the intelligent control module to achieve fast and smooth propulsion and move the wire to the desired position; Step 6. Arrange the equipment: After completing the power maintenance work, gradually reduce the clamping force of the clamp fixing member 10 through the intelligent control module until the wire is completely loosened, return the components of the power maintenance clamp structure to their original positions, turn off the power switch, and clean up the work site to ensure that the equipment is in good standby condition.
