The live fire robot only replaces manual operation to complete the stripping and connection operation of the live fire, and as to how to connect the lead line to the clamp, the traction mechanism needs to be operated manually to complete the traction of the lead line to the overhead operation, which cannot truly avoid personnel overhead operation and manual intervention operation, and cannot realize full-process mechanized operation.

[0046] This invention provides an installation device and method for a drain line connection clamp. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0047] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0048] Please refer to Figures 1 to 13 This embodiment provides an installation device suitable for connecting wire clamps, which can be used in conjunction with a live-line welding robot disclosed in Chinese Patent Publication No. CN117200095A. Figure 1 The dotted line portion, representing the live-line welding robot 50, is a simplified representation of the live-line welding robot. Used together, the two components can connect the drain wire 70 to the cable 60. Specifically, the installation device in this embodiment includes a traction mechanism 10, a wire clamp mechanism 20, a clamping mechanism 30, and an installation mechanism 40.

[0049] like Figure 2As shown, the traction mechanism 10 includes a mounting bracket 11, a movable disc 12, and a traction line 13. The movable disc 12 is rotatably connected to the mounting bracket 11. The mounting bracket 11 is provided with a sheave 14. The traction line 13 passes through the movable disc 12 and then goes around the sheave 14.

[0050] like Figures 2 to 9 As shown, the wire clamp mechanism 20 includes a fixed disc 21, a sliding seat 22, a positioning detector 23, and a clamping head 24. The fixed disc 21 is connected to the free end of the traction line 13. The movable disc 12 is connected to the fixed disc 21 by the tension of the traction line 13. The sliding seat 22 is fixed to the fixed disc 21 and has a groove 221 for the clamping head 24 to slide. The positioning detector 23 is located at the end position of the groove 221. When the clamping head 24 slides away from the positioning detector 23, the clamping head 24 clamps the core of the guide wire 70. When the clamping head 24 slides toward the positioning detector 23, the clamping head 24 releases the core of the guide wire 70 and touches the positioning detector 23.

[0051] like Figures 3 to 4 As shown, the fixed disc 21 has a tapered protrusion 201 at the end away from the sliding seat 22, and the movable disc 12 has a tapered guide hole 101 in the middle. When the traction line 13 is wound up, the traction line 13 brings the fixed disc 21 and other structures of the clamp mechanism 20 close to the traction mechanism 10. At the beginning of the contact, the side of the fixed disc 21 contacts the movable disc 12. Using the contact point as the fulcrum and the contact point and the fixed disc 21 as the lever arm, the clamp mechanism 20 can slowly approach the traction mechanism 10 under the torque applied by the traction line 13. With the cooperation of the protrusion 201 and the guide hole 101, the centers of the fixed disc 21 and the movable disc 12 gradually coincide. The effect is that the movable disc 12 of the traction mechanism 10 adaptively adjusts the angle based on its rotational connection structure, effectively overcoming the counter-traction force generated by the 70° arc of the guide line, and ensuring precise docking.

[0052] like Figures 10 to 11 As shown, the clamping mechanism 30 includes a first insulating rod 31 and a clamp 32 disposed on the top of the first insulating rod 31. The clamp 32 is used to clamp the drain wire 70.

[0053] like Figure 10 As shown, the mounting mechanism 40 includes a second insulating rod 41 and a mounter 42 disposed on the top of the second insulating rod 41. The mounter 42 is used to mount and fix the disc 21 and clamp the clamping chuck 24.

[0054] The installation method for the drain line overlap clamp in this embodiment is performed according to the following steps:

[0055] S1, the wire clamp installation operation stage, includes:

[0056] S11, Pre-fixing of wire clamp: The wire clamp mechanism 20 is pre-fixed on the mounting base 421 of the mounting mechanism 40, and is limited and fixed by the positioning hole 211 of the fixing disc 21 and the positioning post 4211; the worker holds the second insulating rod 41 and lifts the wire clamp mechanism 20 to below the drain line 70;

[0057] S12. Clamping the guide wire: The height of the guide wire 70 on the tower is usually 5 to 8 meters. Another worker holds the first insulating rod 31. This worker can visually determine the position of the guide wire 70, and then control the clamp 32 to clamp the guide wire 70, raise the guide wire 70 above the wire clamp mechanism 20, and keep the guide wire 70 vertically downward.

[0058] S13. Installing the wire clamp: Simultaneously, the operator operates the installation mechanism 40, grasps the second insulating rod 41, aligns the two grippers 424 of the installer 42 with the opening and closing clamps 24 of the wire clamp mechanism 20, and applies inward pressure; then, the second insulating rod 41 is pushed upward, causing the opening and closing clamps 24 to slide along the sliding groove 221 of the sliding frame 22 away from the positioning detector 23. During this process, the wedge-shaped block 223 on the inner side of the sliding frame 22 interacts with the inclined guide surface 2451 of the wire pressing block 245, forcing the two wire pressing blocks 245 to come together, thereby clamping the core of the drain wire 70, completing the pre-installation of the wire clamp mechanism 20, the installer 42 disengages from the wire clamp mechanism 20, and the wire clamp mechanism 20 and the drain wire 70 are combined;

[0059] S2, High-altitude traction and docking stage: The live-line docking robot 50 travels along the high-altitude cable 60 to the predetermined position. After stripping the cable 60 to expose the core wires, the clamping mechanism 30 and the installation mechanism 40 are operated to release the clamping mechanism 20 and the guide wire 70. The traction line 13 is wound up by the reel of the live-line docking robot 50, pulling the fixed disc 21 of the clamping mechanism 20 upward until the traction line 13 is tightened, making the movable disc 12 tightly dock with the fixed disc 21. During this process, the movable disc 12 adaptively adjusts its angle based on the rotating connection structure, effectively overcoming the counter-traction force generated by the curvature of the guide wire 70, ensuring precise docking.

[0060] S3. Release and Wire Retrieval Phase: When the wire retrieval robotic arm of the live-line welding robot 50 needs to remove the guide wire 70, the robotic arm clamps the guide wire 70 and applies a slight downward thrust, driving the opening and closing chuck 24 to slide towards the termination position of the slide groove 221 until it touches the positioning detector 23. At this time, the wedge block 223 releases its constraint on the inclined guide surface 2451, the torsion spring 246 releases its torque to separate the wire pressing block 245, and the guide wire 70 is released; the positioning detector 23 simultaneously sends a signal, and the live-line welding robot 50 then retrieves the wire to perform subsequent splicing operations.

[0061] The installation device in this embodiment mimics human hands working, and by utilizing the operation of the gripper 32 and the installer 42, it avoids the risks of manual climbing and significantly improves safety. At the same time, the movable disc 12 of the traction mechanism 10 adaptively adjusts its angle based on the rotating connection structure, effectively overcoming the counter-traction force generated by the 70° arc of the guide line, ensuring precise docking, greatly reducing the difficulty of pulling the line and the adjustment time, and achieving rapid and accurate transfer. When used in conjunction with the live-line welding robot disclosed in Chinese Patent Publication No. CN117200095A, it can simplify the operation process, reduce construction costs, and completely eliminate the hazards of falling from heights and electric shock.

[0062] Furthermore, the free end of the fixed disc 21 and the traction line 13 can be detachably connected, specifically by binding. Before traction, the free end of the traction line 13 is unwound by the reel of the energized welding robot 50, causing the free end of the traction line 13 to descend to the ground. Then, the staff fixes the free end of the traction line 13 onto the fixed disc 21. During subsequent traction, the entire clamp mechanism 20 can be pulled up to a high altitude.

[0063] As a preferred embodiment, such as Figure 2 As shown, the movable disc 12 is provided with a connecting seat 15, which is rotatably mounted on the mounting bracket 11 via the mounting shaft. The threaded wheel 14 is sleeved on the mounting shaft. The mounting bracket 11 is also provided with an encoder 16 for detecting the rotation angle of the mounting shaft.

[0064] The movable disc 12 is rotatably connected to the mounting shaft of the mounting bracket 11 via the connecting seat 15. The traction line 13 passes through the movable disc 12 and then winds around the coaxially sleeved reel 14. When the fixed disc 21 is pulled taut by the traction line 13 and docks with the movable disc 12, the counter-traction force of the drain line 70 drives the movable disc 12 to rotate the mounting shaft. Moreover, the encoder 16 of the mounting bracket 11 can detect the rotation angle of the mounting shaft in real time and calculate the deflection angle data, which is synchronously fed back to the wire-taking robotic arm of the live-fire robot 50, so that it can dynamically adjust the gripping angle and realize the adaptive deflection guidance of the movable disc 12. This can avoid the interference of the reaction force generated by the curvature of the drain line 70, significantly reduce the adjustment difficulty of the traction line 13, ensure that the wire clamp mechanism 20 is quickly and accurately moved into place, and improve the efficiency of the entire process mechanization.

[0065] like Figure 2 As shown, the movable disk 12 is equipped with a conduction switch, which includes two contacts 17 protruding from the end face of the movable disk 12. The fixed disk 21 is equipped with a conductor 212. When the two contacts 17 are in contact with the conductor 212 at the same time, the conduction switch is turned on.

[0066] The on / off switch of the movable disc 12 achieves electrical conduction through the contact points 17 on the two protruding end faces contacting the conductor 212 of the fixed disc 21. When the traction line 13 is wound into place, causing the clamp mechanism 20 to dock with the traction mechanism 10, the movable disc 12 and the fixed disc 21 fit tightly together, and the two contacts 17 simultaneously touch the conductor 212, triggering the on / off switch to open and automatically powering on the detection circuit (such as the position detector 23) of the clamp mechanism 20. This structure ensures that the detection function is activated only after precise docking, effectively preventing false triggering and improving operational reliability. At the same time, it supports automated signal feedback (such as the position detector 23 sending a release signal), simplifying the process and enhancing the safety of the entire system.

[0067] like Figures 5 to 9 As shown, the sliding support frame 22 has two guide holes 222, which are respectively located on both sides of the slide groove 221; the opening and closing clamp 24 includes two sliding plates 241 that are slidably engaged with the two guide holes 222, a cylindrical pin 242 connected between the two sliding plates 241, two rotating seats 243 sleeved on the cylindrical pin 242, connecting plates 244 respectively fixed to the two rotating seats 243, and two pressure blocks 245 respectively fixed to the two connecting plates 244. A torsion spring 246 is fitted onto the cylindrical pin 242; the two torsion arms of the torsion spring 246 abut against the two connecting plates 244 respectively; a clamping cavity is formed between the two pressure blocks 245 for clamping the core of the drain line 70; the two sides of the pressure block 245 are connected to the inclined guide surface 2451; the inner side of the sliding seat 22 is provided with a wedge block 223 that cooperates with the inclined guide surface 2451; when any rotating seat 243 slides to the end position of the slide groove 221, it abuts against the position detector 23.

[0068] The clamp 24 achieves axial displacement through the sliding engagement of the slide plate 241 and the guide hole 222 of the sliding seat 22. When the external force drives the slide plate 241 to move along the slide groove 221, the cylindrical pin 242 drives the rotating seat 243 to move synchronously. At this time, the inclined guide surface 2451 of the wire clamp 245 interacts with the wedge block 223 on the inner side of the sliding seat 22, converting the horizontal sliding into the radial closing action of the wire clamp 245. With the assistance of the torsion arm of the torsion spring 246 continuously pressing against the connecting plate 244, the two wire clamps 245 are forced to form a stable clamping cavity to lock the core of the drain line 70. When the rotating seat 243 slides to the end position of the slide groove 221 and touches the position detector 23, the wedge block 223 releases the constraint on the inclined guide surface 2451, and the torsion spring 246 releases the torque to make the wire clamp 245 automatically separate, realizing the rapid release of the drain line 70 and the precise detection signal triggering, which significantly improves the reliability of the wire clamp installation and the efficiency of mechanized operation.

[0069] like Figure 9As shown, the clamping block 245 has an arc-shaped notch, and several protruding teeth 2452 are provided inside the arc-shaped notch. When the two clamping blocks 245 are brought together by the interaction force of the wedge block 223 and the inclined guide surface 2451, the clamping cavity formed by the combination of their arc-shaped notches forms a multi-point biting contact with the surface of the core of the guide wire 70 through the protruding teeth 2452. This point-like biting structure significantly increases the contact pressure between the clamping cavity and the core. By utilizing the sharp edges of the protruding teeth 2452 to partially embed into the surface layer of the core, the static friction coefficient is greatly improved, effectively resisting the risk of slippage of the guide wire 70 under the action of wind, swaying or traction at high altitudes, ensuring the clamping stability of the clamping mechanism 20, and avoiding the core pressure damage or deformation caused by traditional planar clamping.

[0070] like Figures 10 to 12 As shown, the clamp 32 includes a fixed block 321, a movable block 322, a round-headed pin 323, a first spring 324, and a first traction rope 325. The fixed block 321 is fixed to the top of the first insulating rod 31. The round-headed pin 323 is connected to one end of the movable block 322. The fixed block 321 is provided with a movable hole for the round-headed pin 323 to move. The first spring 324 is sleeved on the round-headed pin 323 and is located between the fixed block 321 and the movable block 322. The first traction rope 325 is connected to one end of the movable block 322 and passes through the fixed block 321. The fixed block 321 and the movable block 322 cooperate to form a clamping hole 326 for clamping the drain line 70.

[0071] Workers pull the first traction rope 325 of the clamp 32 downwards, driving the movable block 322 to overcome the tension of the first spring 324 and slide along the round-headed pin 323 towards the fixed block 321. This causes the arc-shaped notch of the fixed block 321 to engage with the movable block 322, closing the clamping hole 326 and thus locking the core of the drain line 70. When the first traction rope 325 is released, the first spring 324 pushes the movable block 322 to reset along the round-headed pin 323, and the clamping hole 326 automatically expands to release the drain line 70. This design replicates the manual gripping action, improves the traction force transmission efficiency through the guide ring 327, and, combined with the self-resetting characteristic of the first spring 324, enables quick clamping or releasing of the drain line 70 with one hand. This ensures that the drain line 70 remains vertically stable during ground operations, reduces the risks of working at heights, and improves the safety and smoothness of the installation process.

[0072] like Figure 12As shown, the fixed block 321 is provided with a guide ring 327. The first traction rope 325 passes through the guide ring 327 and extends to the bottom of the first insulating rod 31. The guide ring 327 provides a low-friction directional guiding channel for the first traction rope 325, so that the traction force is efficiently transmitted to the movable block 322 along the axial direction of the first insulating rod 31. By constraining the swing amplitude of the first traction rope 325 and eliminating direct friction loss with the surface of the insulating rod, the smoothness of operation and the efficiency of force transmission are improved. When the operator pulls down the first traction rope 325 with one hand on the ground, the guide ring 327 ensures that the force accurately drives the movable block 322 to close the clamping hole 326, simultaneously reducing the wear of the first traction rope 325 and extending the equipment life. When the first traction rope 325 is released, the limiting and guiding characteristics of the guide ring 327 assist the first spring 324 to quickly reset the movable block 322, realizing the switching of clamping or releasing the drain line 70.

[0073] like Figure 13 As shown, the installer 42 includes a mounting base 421, a guide rail 422, two sliders 423, two grippers 424, two connecting rods 425, a movable seat 426, a column 427, a second spring 428, and a second traction rope 429. The mounting base 421 is fixed to the top of the second insulating rod 41. The guide rail 422 is fixed laterally to the mounting base 421. The two sliders 423 slide synchronously in opposite directions or synchronously in the opposite direction along the guide rail 422. The two grippers 424 are respectively fixed to the two sliders 423 and are used to clamp the clamping head 24. The connecting rods 425 are connected to the... Between the gripper 424 and the movable seat 426, the column 427 is fixed vertically to the mounting base 421 by a positioning plate, the movable seat 426 slides vertically with the column 427, the second spring 428 is sleeved on the column 427 and located between the positioning plate and the movable seat 426, the bottom of the movable seat 426 is connected to a rope end binding post 4261, and the second traction rope 429 is connected to the rope end binding post 4261; the mounting base 421 is also provided with at least two positioning posts 4211, and the fixed disc 21 is provided with positioning holes 211 that are inserted and engaged with the positioning posts 4211.

[0074] When the operator operates the installation mechanism 40, the positioning pin 4211 of the mounting base 421 is first inserted into the positioning hole 211 of the fixed disc 21 of the wire clamp mechanism 20 to achieve pre-positioning, ensuring that the installer 42 and the wire clamp mechanism 20 are precisely aligned; then the second traction rope 429 at the bottom of the second insulating rod 41 is pulled down, and the movable base 426 is pulled down along the column 427 through the rope end binding post 4261, compressing the second spring 428 sleeved on the column 427. At this time, the vertical displacement of the movable base 426 drives the two connecting rods 425 to rotate relative to each other, forcing the two sliders 423 fixed at the end of the connecting rods 425 to slide synchronously in opposite directions along the guide rail 422, driving the two grippers 424 to close and clamp the clamping head 24. After clamping is completed, push the second insulating rod 41 upward to raise the wire clamp mechanism 20 as a whole and connect it with the vertically fixed drain wire 70. The mechanical interlock between the wedge block 223 and the inclined guide surface 2451 automatically triggers the opening and closing clamp head 24 to lock the core of the drain wire 70.

[0075] This embodiment transforms the linear action of manually pulling down the second traction rope 429 into a horizontal opposing clamping force of the gripper 424. Combined with the pre-positioning function of the positioning column 4211, high-altitude alignment can be achieved. When the rope is released, the second spring 428 drives the movable seat 426 to quickly reset, simultaneously releasing the clamping state. The entire process can be controlled with one hand. Its mechanical transmission efficiency and self-resetting characteristics significantly reduce the intensity of ground operations, ensuring accurate and reliable installation of the drainage line 70 and the clamping mechanism 20 without manual climbing.

[0076] like Figure 10 As shown, the installation mechanism 40 also includes a rope puller 43 located at the lower end of the second insulating rod 41. The rope puller 43 includes a first handle 431 fixed to the second insulating rod 41 and a second handle 432 hinged to the first handle 431. A second traction rope 429 is connected to the swing end of the second handle 432. When the operator holds the second insulating rod 41 of the installation mechanism 40 with one hand, pressing the second handle 432 of the rope puller 43 with the thumb drives the swing end of the second handle 432 to pull down the second traction rope 429. This action is transmitted to the movable seat 426 via the rope end binding post 4261, causing it to move down along the column 427 to compress the second spring 428, simultaneously driving the connecting rod 425 to rotate and close the two grippers 424 to clamp the clamping head 24. After releasing the pressing force, the second spring 428 pushes the movable seat 426 to reset, the second handle 432 automatically rebounds, and the grippers 424 release the clamping state.
