Description

Technical Field

[0001] This invention relates to the field of wiring device technology, specifically to a wire clamp installation tool and wiring method. Background Technology

[0002] In current power distribution systems, live-line working is becoming increasingly widespread. As societal demands for power quality and reliability rise, the continuous and stable transmission of electrical energy is becoming ever more crucial. Live-line wiring is a common operation in scenarios such as connecting new customers, upgrading lines, and installing pole-mounted equipment, and is performed frequently.

[0003] The patent application CN111130020B discloses a clamp installation tool and intelligent equipment. The background technology raises the following problem: due to the compact structure and small safety distance margin of the distribution network equipment, phase-to-phase and phase-to-ground short circuits are easily caused when the lead wire is disconnected. The operation of the insulated bucket truck still requires personnel to be raised to the air before the operation can be carried out, which also poses the danger of working at height. Moreover, working in a high-voltage and complex electromagnetic environment results in high labor intensity and harms the health of the workers.

[0004] Based on existing technologies, the following are the main challenges in live-line wiring work on high-voltage circuits at this stage: (1) In order to ensure safety, traditional operation methods usually require disconnecting the power supply on the input side of the line. Power outage operations will cause power outages for users, which can easily lead to production losses for users such as medium and large industrial enterprises that are heavily dependent on electricity.

[0005] (2) Introducing live-line working robots can reduce the labor intensity of personnel to a certain extent and is easier to control precisely than manual work. However, due to the limitations of existing wiring tools, the process of robots completing wiring work is cumbersome and the operation process is complicated, resulting in unsatisfactory overall work efficiency and success rate.

[0006] (3) When connecting wires with insulated clamps, the insulated clamps may damage the internal conductors when they pierce the insulation layer on the surface of the cable with a piercing needle, which may affect the stability of long-term use. In order to solve the above problems, a clamp installation tool and wiring method are proposed. Summary of the Invention

[0016] The present invention also provides a method for using a wire clamp installation tool, wherein the method includes the following steps: S1: Install the insulating clamps along the limit slide rails, and then place the lead wires and guide wires to be connected along the guide opening and guide rod to the two terminals of the insulating clamps respectively; S2: After connecting the overhead line and the lead wire, tighten the nut of the insulating clamp through the installation mechanism to connect the lead wire and the overhead line.

[0017] This invention provides a wire clamp installation tool and wiring method. Compared with the prior art, it has the following advantages: 1. This invention allows wiring to be completed without disconnecting the power supply through a limiting bracket and installation mechanism. This avoids power outages for users due to construction, ensures continuous production for medium and large enterprises that are highly dependent on electricity, reduces economic losses, and directly responds to the high demand for continuous power supply in social production; By using a camera for automatic identification and positioning, and a motor-driven system to automatically complete a series of actions such as wire fixing, nut tightening, and wire clamping, the originally cumbersome, manual, multi-step process is integrated into a continuous automated process. This greatly improves the efficiency of a single operation, adapts to complex on-site environments, and prevents installation failures or equipment damage caused by inaccurate positioning or improper force.

[0018] 2. In this invention, when the nut of the insulating clamp is tightened, the force of the pressure plate clamping the nut sleeve becomes unstable after the torque reaches a certain level. Furthermore, because the length of the clamping plate and pressure plate along the radial direction of the nut sleeve is less than the side length of the regular hexagonal inner wall of the nut sleeve, after a certain torque is reached, the clamping plate and pressure plate will shift along the inner wall of the nut sleeve, and the nut sleeve will not rotate with the rotation of the clamping plate and pressure plate. This avoids significant damage to the internal conductor caused by the piercing needle of the insulating clamp after penetrating the cable surface insulation layer, facilitating wiring and improving the stability of subsequent conductivity.

[0019] 3. This invention utilizes a structure consisting of a hinge, a rod, and a frame. Based on the lever principle, the pressure sensor is installed on the side of the clamping plate away from the nut sleeve. This ensures that the clamping plate and pressure plate can fit into the nut sleeve without affecting the monitoring of the clamping force. Furthermore, by using the lever principle, the hinge is positioned close to the rod, making the lever arm of the frame longer than that of the rod. This results in a larger range of motion of the frame when the rod is squeezed, allowing the pressure sensor to receive pressure information more stably and accurately.

[0020] 4. The present invention enables the clamping plates to move closer to or further away from each other by matching the threaded connection direction of the threaded rod and the slider and the transmission direction of the bevel gear and the bevel plate. This facilitates clamping and fixing the nut sleeve from the inner wall of the nut sleeve, making it easier to replace nut sleeves of different sizes, and thus facilitating the connection of lead wires and guide wires of different sizes. By pressing the pressure plate and clamp against the inner wall of the nut sleeve, it is easy to fix the nut sleeve without affecting the subsequent rotation of the nut sleeve, thus not affecting the tightening of the nut of the insulating clamp. The clamping plates are connected by guide seats, guide rods and guide holes to improve the stability of the clamping plates when they rotate under the drive of the second servo motor, without affecting the movement of the clamping plates.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1, please refer to Figures 1-6 A wire clamp installation tool includes a base plate 1, a nut sleeve 28, and a housing 4 fixedly mounted on the top of the base plate 1. It also includes a movable bracket 21 slidably mounted on the top of the base plate 1 and a movable plate 22 fixedly mounted inside the movable bracket 21. The side wall of the movable bracket 21 is provided with spaced-apart installation mechanisms 24. The tool further includes: The slide rail 19 is fixedly installed on the top of the base plate 1. A slide plate is provided on the inner side of the slide rail 19. The top of the slide plate is fixedly connected to the bottom of the movable bracket 21. An electric push rod 23 is fixedly installed on the top of the base plate 1. The telescopic shaft of the electric push rod 23 is fixedly connected to the outer side of the movable bracket 21 so as to drive the movable bracket 21 to move along the slide rail 19. A fixed bracket 121 is fixedly installed on the side of the base plate 1 near the nut sleeve 28. A limiting panel 7 and a limiting bracket 12 are fixedly installed on the top two sides of the fixed bracket 121 respectively. A guide rod 8 with an inclined design is fixedly installed on the top of the limiting bracket 12. A limiting slide rail 11 for installing insulating wire clamps is fixedly installed on the inner side of the limiting panel 7. A laser emitter 13 is installed on the outer side of the limiting panel 7. The clamping frame 9 is fixedly installed on the outside of the fixed bracket 121. A push rod 10 is slidably installed on the outside of the clamping frame 9. A third servo motor 15 for driving the push rod 10 to move is fixedly installed on the outside of the clamping frame 9. A guide port 16 is fixedly installed on the side of the clamping frame 9 away from the fixed bracket 121.

[0025] An adjustment bracket 5 is fixedly provided on the top of the outer casing 4, and a camera 6 is fixedly provided on the adjustment end of the adjustment bracket 5; A power switch 14, an external network interface 3, and a fuse 2 are respectively provided on both sides of the outer wall of the outer casing 4; An installation plate 17 is fixedly provided on the upper end of the inner wall of the outer casing 4, and a control component 18 and a main control board 20 are provided on the top of the installation plate 17. A connector 25 is fixedly provided at the bottom of the base plate 1. A force control device 26 is provided at the bottom of the connector 25. A data cable interface 27 is provided on the outside of the force control device 26. A flange is fixedly provided at the bottom of the force control device 26.

[0026] In the implementation of this invention, the insulating wire clamp used for wiring can be installed from above along the limiting slide rail 11 with the wire clamp installation tool. The front and rear clamps of the insulating wire clamp are respectively attached to the limiting bracket 12 and the limiting panel 7 to facilitate subsequent wiring. The insulating wire clamp is prior art and is not shown in the figure, so it will not be described in detail here.

[0027] Subsequently, the external robotic arm, via the flange at the bottom of the force control device 26, moves the entire assembly, including the base plate 1, to the pre-wiring operation position. Camera 6 observes and identifies the target overlap on the wire and calculates its pose. The robotic arm continues to move according to the calculated pose until it reaches the insulating clamp installation position. The wire will then enter the upper half of the insulating clamp between the limit bracket 12 and the limit panel 7 along the wire guide rod 8. Afterwards, another external robotic arm and wire gripping tool carry the lead wire to the pre-threading operation position, where the lead wire enters the lower half of the insulating clamp along the guide opening 16. During this process, the laser emitter 13 on the side of the limit panel 7 emits a laser beam forward. If there is a wire or lead wire in front, the laser beam will be blocked. After detecting the blocked laser signal, the system considers both the wire and lead wire to be connected to the insulating clamp. Then, the main control board 20 controls the third servo motor 15 to work, which in turn drives the push rod 10 inward, thereby moving the clamping frame 9 inward to fix the inserted lead wire.

[0028] Subsequently, the main control board 20 controls the second servo motor 241 to rotate, which in turn drives the first rotating rod 242 and the second rotating rod 246 to rotate, thereby driving the second connecting rod 2491 and the nut sleeve 28 to rotate. At the same time, the control component 18 controls the electric push rod 23 to push the moving bracket 21 closer to the lead wire, thereby driving the nut sleeve 28 to move inward. The nut sleeve 28 continues to rotate while moving inward. If it comes into contact with the bolt on the back of the insulating clamp during the rotation process, the bolt will gradually enter the nut sleeve 28 and be driven to rotate synchronously. At this time, the insulating clamp will gradually clamp the line wire and the lead wire. When it is fully clamped, the wiring operation is completed.

[0029] After the operation is completed, the control component 18 controls the electric push rod 23 to drive the moving bracket 21 and nut sleeve 28 to move outward, completing the "rod retraction". Afterward, the wire clamps and other components can be removed from the limit rail 11. The wiring is now complete, facilitating the next wiring attempt.

[0030] The third servo motor 15 drives the push rod 10 to move horizontally via a threaded transmission, thereby moving the clamping frame 9 to clamp the lead wire. The transmission method of the third servo motor 15 driving the push rod 10 is existing technology and will not be described in detail here.

[0031] Power switch 14 controls the device's start and stop. External network interface 3 is used to connect to an external host. Fuse 2 is used to prevent damage to the device due to excessive internal current.

[0032] An antenna is also installed on the outer surface of the outer casing 4, which is not shown in the figure. The antenna is connected to the main control board 20. The main control board 20 can send a WiFi signal, and the antenna can amplify the signal so that the external host can access the main control board 20 via WiFi, which is convenient for actual operation.

[0033] The angle of camera 6 can be adjusted by adjusting bracket 5, allowing for close-up observation of target leads and lines. Camera 6 is connected to the main control board 20 via a USB 3.0 to microUSB external hard drive data cable.

[0034] The force control device 26 senses forces from all directions of the robotic arm and end effector, and adjusts the posture of the robotic arm and end effector based on the force control feedback to ensure successful completion of the task. The data cable interface 27 of the force control device 26 can transmit the force control feedback data to the main control board 20.

The bottom of the clamping plate 2496 is provided with a third groove and a fourth groove for fitting the limiting rod 3096 and the limiting block 3095.

[0039] The side of the clamping plate 2496 away from the connecting plate 302 is designed to be inclined so that it can be inserted into the nut sleeve 28, and so that the side of the clamping plate 2496 near the connecting plate 302 can have space to install the pressure sensor 306. The inner wall of the hinge groove 3091 is reserved with space for the rod body 3093, the frame body 307 and the pressure plate 304 to rotate; One of the limiting rods 3096 and the limiting block 3095 is located inside the frame 307 to limit the movement of the limiting rod 3096 and the limiting block 3095 relative to the frame 307.

[0040] The mounting mechanism 24 also includes: The guide seat 30 is fixedly disposed at one end of the disc 243 away from the second connecting rod 2491 and located on the side of the clamping plates 2496 that are close to each other. The side wall of the guide seat 30 is provided with guide holes 301 arranged at intervals. The guide rod 309 is fixedly installed on the inner side of the clamping plate 2496 and sleeved in the guide hole 301 to limit the rotation of the clamping plate 2496 along the center line of the disk 243.

[0041] The mounting mechanism 24 also includes: The first servo motor 2492 is fixedly installed inside the second connecting rod 2491, and the output shaft of the first servo motor 2492 is fixedly provided with a bevel gear disk 2497. The threaded rod 2494 is rotatably disposed on the inner wall of the slide groove 2493 and is threadedly connected to the slider. The ends of the threaded rod 2494 that are close to each other are fixedly sleeved with bevel gears 2498, which mesh with bevel gear discs 2497. A connecting flange 249 is fixedly disposed at one end of the first connecting rod 248 and the second connecting rod 2491 that are close to each other, for connecting the first connecting rod 248 and the second connecting rod 2491. The second servo motor 241 is fixedly mounted on the outside of the movable bracket 21. The output shaft of the second servo motor 241 is fixedly mounted with a second rotating rod 246 via a coupling. The first gear 244 and the second gear 245 are respectively fixedly mounted on the side wall of the second rotating rod 246 and the first rotating rod 242 located on the inner side of the movable bracket 21. The first gear 244 and the second gear 245 mesh with each other.

[0042] In practical implementation, when the nut of the insulating clamp is tightened by the installation mechanism 24 to fix the lead wire and the guide wire, the first servo motor 2492 first drives the clamping plates 2496 to move away from each other, so that the clamping plates 2496 and the pressure plate 2495 clamp and fix it from the inner wall of the nut sleeve 28. After fixing, the second servo motor 241 is started. The output shaft of the second servo motor 241 drives the second rotating rod 246 and the second gear 245 to rotate, thereby driving the first gear 244 and the first rotating rod 242 to rotate, thereby driving the first connecting rod 248, the second connecting rod 2491, the disc 243 and the clamping plate 2496 to rotate, thereby causing the nut sleeve 28 to rotate, so as to tighten and fix the nut on the insulating clamp, thereby connecting the lead wire and the guide wire.

[0043] During the tightening of the nut of the insulating clamp, the torque is monitored in real time by the torque sensor 247, and the force of the pressure plate 2495 clamping the nut sleeve 28 is monitored in real time by the pressure sensor 306. Through a preset program, the force of the pressure plate 2495 clamping the nut sleeve 28 is made so that it can no longer stably clamp the nut sleeve 28 after the torque reaches a certain level. Since the length of the clamping plate 2496 and the pressure plate 2495 along the radial direction of the nut sleeve 28 is less than the side length of the regular hexagon of the inner wall of the nut sleeve 28, the clamping plate 2496 and the pressure plate 2495 will shift along the inner wall of the nut sleeve 28 after a certain torque is reached. At this time, the nut sleeve 28 will not rotate with the rotation of the clamping plate 2496 and the pressure plate 2495. Thus, when tightening the nut to fix the lead wire and the cable, the piercing needle of the insulating clamp is prevented from causing great damage to the internal conductor after passing through the insulation layer of the cable surface. This facilitates wiring and improves the stability of subsequent conductivity.

[0044] The output shaft of the first servo motor 2492 drives the bevel gear disk 2497 and bevel gear 2498 to rotate, thereby synchronously driving the threaded rods 2494 arranged in a ring array to rotate. Through the threaded connection direction of the threaded rods 2494 and the slider, and the transmission direction of the bevel gear disk 2497 and the bevel gear 2498, the clamping plates 2496 can move closer to each other or further away from each other. This facilitates the clamping and fixing of the nut sleeve 28 from the inner wall of the nut sleeve 28, making it easier to replace nut sleeves 28 of different sizes, and thus facilitating the connection of lead wires and guide wires of different sizes.

[0045] By pressing the pressure plate 2495 and clamping plate 2496 against the inner wall of the nut sleeve 28, it is convenient to fix the nut sleeve 28 without affecting the subsequent rotation of the nut sleeve 28, thus not affecting the tightening of the nut of the insulating clamp. The pressure plate 2495 and clamping plate 2496 are connected by the limiting rod 3096 and the limiting block 3095, so that the pressure plate 2495 can be raised and lowered. When the pressure plate 2495 presses against the inner wall of the nut sleeve 28, the pressure plate 2495 drives the top rod 3092 and the top block 3094 to squeeze the rod body 3093. Under the action of the hinge 308, the rod body 3093 causes the frame 307 to move in the opposite direction, so as to drive the pressure plate 304 to press the pressure sensor 306 downward. This makes it easier to control the force of the pressure plate 2495 clamping the nut sleeve 28, so as to cooperate with the torque sensor 247 to stably pierce the surface insulation layer of the cable and reduce damage to its internal conductor.

[0046] Through the structure of hinge 308, rod 3093, and frame 307, and based on the lever principle, the pressure sensor 306 is installed on the side of clamping plate 2496 away from nut sleeve 28. This ensures that the dimensions of clamping plate 2496 and pressure plate 2495 can be inserted into nut sleeve 28 without affecting the monitoring of clamping force. In addition, through the lever principle, hinge 308 is brought closer to rod 3093, so that the lever arm of frame 307 is longer than that of rod 3093. Therefore, when squeezing rod 3093, frame 307 moves a larger amplitude, so that pressure sensor 306 can receive pressure information more stably and accurately.

[0047] The clamping plate 2496 is connected by the guide seat 30, the guide rod 309 and the guide hole 301 to improve the stability of the clamping plate 2496 rotating under the drive of the second servo motor 241, without affecting the movement of the clamping plate 2496.

[0048] The connecting flange 249 facilitates the connection of the first link 248 and the second link 2491 without affecting the use of the torque sensor 247, making it convenient for practical use.

[0049] This invention also provides a method for using a wire clamp installation tool. The method includes the following steps: S1: Install the insulating wire clamp along the limiting slide rail 11, and then place the lead wire and the guide wire to be connected along the guide port 16 and the guide rod 8 respectively at the two terminals of the insulating wire clamp; S2: After connecting the overhead line and the lead wire, tighten the nut of the insulating clamp through the mounting mechanism 24 to connect the lead wire and the overhead line.
