Description

Technical Field

[0001] This invention belongs to the field of substation maintenance technology, specifically relating to a mechanical device for assisting in disconnecting and connecting leads. Background Technology

[0002] As the scale of the power system continues to expand, the number of substations is increasing year by year. In order to ensure power safety, it is necessary to conduct regular maintenance and shutdown. Among them, disconnecting and reconnecting the lead wire is an important part of many maintenance tasks. The current work process is as follows: two maintenance personnel climb up to the substation and work together in a high-altitude environment. One person is responsible for fixing the lead wire, while the other person uses mechanical tools to disconnect and reconnect the screws on the lead wire mating surface. This work process requires the cooperation of two people. If the two people do not cooperate well or their operating rhythm is inconsistent, it will not only lead to low operating efficiency, but also easily cause safety accidents. In addition, the lead wire is heavy, and relying on manpower to fix it in a high-altitude environment increases the intensity of the work. Summary of the Invention

[0003] This invention provides a mechanical device to assist in the splicing and disconnection of leads, aiming to solve the technical problems of high labor intensity and labor costs, and low work efficiency in the existing lead splicing and disconnection process.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A mechanical device for assisting in the splicing and disconnection of lead wires is provided, including an aerial work platform, a working platform, and a wire clamp. The aerial work platform includes a vehicle body, a drive platform mounted on the vehicle body, and an operating arm fixed on the drive platform. A support arm is provided on the vehicle body to support the drive platform on the ground, keeping it horizontal. The drive platform is used to drive the operating arm to rotate. The operating arm includes a first segment, a second segment, a third segment, and a fourth segment that are sequentially hinged. The working platform is hinged to the free end of the fourth segment. A connecting part is provided at the bottom of the working platform. The wire clamp is located on the working platform and has degrees of freedom to move along the X and Y directions. The wire clamp is used to clamp and fix the lead wire. When the mechanical device is in a stopped state, the support arm is parallel to the vertical direction, the second segment is parallel to the horizontal direction, the fourth segment is parallel to the vertical direction, the first segment and the third segment intersect, and the connecting part is connected to the top end of the support arm.

[0005] In one possible implementation, the vehicle body further includes a support foot located at the free end of the support arm, and a connecting rod connecting the support arm and the support foot. The support foot is conical, and a slider is sleeved on the connecting rod. The end face of the slider away from the support foot is a guide slope that is aligned with the outer peripheral surface of the cone. The connecting part is a sleeve located at the bottom of the working platform. The sleeve is provided with a sliding groove located on the side wall and extending horizontally, a locking block that slides in the sliding groove, and a first spring connected to the locking block. The first spring has a pre-tightening force that causes the locking block to protrude from the inner circumferential surface of the sleeve. When the support foot is facing upward, the slider separates from the support foot due to gravity, and the support foot extends into the sleeve. The locking block abuts against the end face of the support foot near the slider to achieve connection. When unlocking, the working platform moves downward, causing the locking block to move to the end face of the slider away from the support foot. The locking block slides down to the outer circumference of the support foot under the action of the guide slope and releases the lock with the support foot.

[0006] In one possible implementation, the drive platform includes a first motor mounted on the vehicle body, a rotary table drivenly connected to the output shaft of the first motor, and a limiting mechanism mounted on the vehicle body and located at the bottom of the rotary table. The rotary table is provided with a plurality of guide grooves and a cylinder coaxial with the rotary table. The limiting mechanism includes a plurality of limiting blocks that slide in cooperation with each of the guide grooves. A connecting rod is connected between the limiting block and the vehicle body. One end of the connecting rod is hinged to the limiting block, and the other end of the connecting rod is hinged to the vehicle body. When the first motor drives the rotary table to rotate, the multiple limiting blocks slide in the corresponding guide grooves and gradually come into contact with the outer periphery of the cylinder.

[0007] In one possible implementation, the work platform includes a fixed frame, a fixed platform fixed to the fixed frame, and a deformable platform rotatably connected to the fixed frame. The deformable platform has an unfolded first state and a folded second state. In the first state, the deformable platform is a ladder extending from the fixed frame to the ground. In the second state, the top surface of the deformable platform is flush with the top surface of the fixed platform to form a platform for supporting workers.

[0008] In one possible implementation, the deformable platform includes a first frame hinged to the fixed frame and a second frame hinged to the first frame. Both the first frame and the second frame are provided with climbing poles, and the back of the first frame is provided with a foot pedal. In the second state, the first frame and the second frame are stacked vertically, and the foot pedal is aligned with and flush with the fixed platform. In the first state, the first frame and the second frame are parallel and extend towards the ground to form the ladder.

[0009] In one possible implementation, the work platform is provided with a safety railing, and the safety railing has an openable safety door on the side near the hinged side of the first frame and the fixed frame.

[0010] In one possible implementation, the working platform is fixed with an adjustment mechanism, which includes a first linear module extending along the Y direction, a second linear module slidably engaged with the first linear module and extending along the X direction, and a mounting bracket slidably engaged with the second linear module. The wire clamp is fixed to the mounting bracket.

[0011] In one possible implementation, the outer periphery of the work platform is provided with an annular slide rail and a fixed rod connecting the slide rail and the work platform. The adjustment mechanism further includes an adjustment block, which is slidably connected to the slide rail, and the first linear module is fixed on the adjustment block. The back of the first linear module is provided with an upper clamping block and a lower clamping block. The opposite surfaces of the upper clamping block and the lower clamping block are provided with grooves. The adjusting block is a ring structure and is rotatably fitted into the groove. The side wall of the adjusting block is provided with an opening. When the opening of the adjusting block faces upward or downward, the upper clamping block or the lower clamping block covers the opening. When the opening of the adjusting block faces away from the first linear module, the fixing rod can pass through the opening.

[0012] In one possible implementation, the mounting bracket includes a movable seat slidably fitted to the second linear module, a U-shaped frame hinged to the movable seat, a tripod hinged to the U-shaped frame, and a wire clamp hinged to the tripod. The axial direction of the hinge axis between the movable seat and the U-shaped frame is defined as a first axial direction, the axial direction of the hinge axis between the U-shaped frame and the tripod is defined as a second axial direction, and the axial direction of the hinge axis between the tripod and the wire clamp is defined as a third axial direction. The first axial direction is perpendicular to the second axial direction, and the second axial direction is parallel to the third axial direction.

[0013] In one possible implementation, the wire clamp includes a first clamping part, a second clamping part hinged to the first clamping part, and an adjusting piece slidably engaged with the second clamping part. A compression spring is also provided between the adjusting piece and the second clamping part. The adjusting piece is located between the first clamping part and the second clamping part and is used to move in a direction close to or away from the first clamping part. The adjusting piece has a V-shaped structure with its opening facing the first clamping part and is used to cooperate with the first clamping part to clamp the lead wire.

[0014] Compared with the prior art, the solution shown in this application embodiment adopts a four-segment articulated structure for the operating arm. Combined with the rotation function of the drive platform, this allows the working platform to reach working positions at different heights and angles, covering complex lead wire layout scenarios within substations. Multi-position operations can be completed without manual movement of the equipment. Furthermore, the folded support arm is located at the top of the vehicle body and within the inner ring of the support arm, without occupying additional space on the vehicle's perimeter, facilitating storage and saving space. During operation, the support arm rests on the ground, keeping the drive platform level and effectively counteracting tilting moments during high-altitude operations, preventing equipment tipping and improving operational safety. Through the design of each support arm… The adjustable mechanism can adapt to uneven working conditions, keeping the top surface of the vehicle level. This improves the stability of the operating arm and work platform, preventing accidents caused by vehicle tilting during operation. When the support arm is extended, it rests on the bottom surface of the vehicle's outer perimeter, increasing the contact area between the vehicle and the ground and enhancing the vehicle's reliability. The wire clamp has X and Y-axis freedom of movement, allowing for precise alignment of the lead wire. This replaces manual wire fixing, reducing the labor intensity of operators and avoiding the instability caused by manual fixing. By fixing the lead wire with the wire clamp, the number of operators is reduced to one, avoiding the problem of low work efficiency caused by poor coordination between two people.

Detailed Implementation

[0017] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present 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 merely illustrative of the present invention and are not intended to limit the present invention.

[0018] Please refer to the following: Figures 1 to 10The mechanical device for assisting in the splicing and disconnecting of leads provided by the present invention will now be described. The mechanical device for assisting in the splicing and disconnecting of leads includes an aerial work platform, a working platform 40, and a wire clamp 50. The aerial work platform includes a vehicle body 10, a drive platform 20 mounted on the vehicle body 10, and an operating arm 30 fixed on the drive platform 20. A support arm 11 is provided on the vehicle body 10, which supports the drive platform 20 to maintain its horizontal position. The drive platform 20 drives the operating arm 30 to rotate. The operating arm 30 includes a first segment 31, a second segment 32, a third segment 33, and a fourth segment 34 that are sequentially hinged together. The working platform 40 is hinged to the free end of the fourth segment 34. The bottom of the working platform 40 is provided with a connecting part. The wire clamp 50 is provided on the working platform 40 and has the freedom to move along the X and Y directions. The wire clamp 50 is used to clamp and fix the lead wire. When the mechanical equipment is in the stopped state, the support arm 11 is parallel to the vertical direction, the second segment 32 is parallel to the horizontal direction, the fourth segment 34 is parallel to the vertical direction, the first segment 31 and the third segment 33 intersect, and the connecting part is connected to the top end of the support arm 11.

[0019] It should be noted that the vehicle body 10 can adopt the commonly used models of existing aerial work platforms. The walking system of the vehicle body 10 can adopt tracked wheels or four independent wheels. Its rated load must meet the weighing requirements. It is equipped with a diesel engine or electric motor to drive the wheels for walking, and is also equipped with a hydraulic power steering system. In order to improve safety, parking brake, dual-circuit hydraulic brake, vehicle body alarm and other systems can also be installed in the vehicle body 10.

[0020] Compared with the prior art, the auxiliary wire splicing and disconnecting mechanical equipment provided in this embodiment adopts a four-segment hinge structure for the operating arm 30. Combined with the rotation function of the drive platform 20, this allows the working platform 40 to reach working positions at different heights and angles, covering complex wire layout scenarios within substations. It can complete multi-position operations without manual equipment movement. Furthermore, the folded support arm 11 is located on top of the vehicle body 10 and within its inner ring, without occupying additional space on the vehicle body 10's perimeter, facilitating storage and saving space. During operation, the support arm 11 supports the ground, keeping the drive platform 20 level, effectively counteracting the tilting moment during high-altitude operations, preventing equipment tipping, and improving operational safety. This is achieved through the various support... The adjustable arm 11 can adapt to uneven working conditions, keeping the top surface of the vehicle body 10 level. This improves the stability of the operating arm 30 and the working platform 40, preventing the vehicle body 10 from tilting during operation and causing safety accidents. When the support arm 11 is extended, it supports the bottom surface of the outer periphery of the vehicle body 10, increasing the contact area between the vehicle body 10 and the ground and improving the reliability of the vehicle body 10. The wire clamp 50 has X and Y degree of freedom of movement, which can accurately connect to the lead wire position, replacing manual fixing of the lead wire, reducing the labor intensity of the operators, and avoiding the instability caused by manual fixing. By fixing the lead wire with the wire clamp 50, the number of operators is reduced to one, avoiding the problem of low work efficiency caused by poor coordination between two people.

[0021] In some embodiments, a specific implementation of the support arm 11 may employ the following method: Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3The support arm 11 is hinged to the top of the vehicle body 10. The vehicle body 10 is provided with a first hydraulic system that is hinged to the support arm 11. The first hydraulic system is used to control the extension and retraction of the support arm 11. The support arm 11 is a three-layer nested structure consisting of a fixed section, a first-stage telescopic section, and a second-stage telescopic section. Wear-resistant guide strips are welded to the inner wall. A connecting seat for mounting the support arm 11 is located on the top of the vehicle body 10. The fixed section is hinged to the connecting seat. A hydraulic port and mechanical locking hole are pre-drilled at the bottom. The first-stage telescopic section can slide axially along the fixed section, and the second-stage telescopic section can slide axially along the first-stage telescopic section. Dustproof sealing rings are installed at the connections between the fixed section, the first-stage telescopic section, and the second-stage telescopic section. A double-acting hydraulic cylinder is built into the connection between the fixed section and the first-stage telescopic section, and between the first-stage telescopic section and the second-stage telescopic section, to achieve telescopic adjustment of each section. A level sensor is installed on the vehicle body 10. When the vehicle body 10 is leveled, the level sensor transmits a signal to the actuator (control system), which then controls the first hydraulic system to shut down. Similarly, the angle adjustment between the fixed section and the connecting seat is also driven by a hydraulic cylinder. One end of the hydraulic cylinder is hinged to the vehicle body 10, and the other end is hinged to the support arm 11. By controlling the telescopic movement of this hydraulic cylinder, the angle of the support arm 11 is adjusted.

[0022] The rotation of the support arm 11 is controlled by a servo motor to adjust its angle.

[0023] In some embodiments, a specific connection method between the above-mentioned work platform 40 and the support arm 11 can be as follows: Figures 2 to 3 The structure shown. See also Figures 2 to 3 The vehicle body 10 also includes a support foot 12 located at the free end of the support arm 11, and a connecting rod 13 connecting the support arm 11 and the support foot 12. The support foot 12 is conical, and a slider 14 is sleeved on the connecting rod 13. The end face of the slider 14 facing away from the support foot 12 is a guide slope that is aligned with the outer peripheral surface of the cone. The connecting part is a sleeve 41 located at the bottom of the working platform 40. The sleeve 41 is provided with a sliding groove 42 located on the side wall and extending horizontally, a locking block 43 that is slidably engaged with the sliding groove 42, and a first spring 44 connected to the locking block 43. The first spring 44 has a pre-tightening force that causes the locking block 43 to protrude from the inner circumferential surface of the sleeve 41. When the support foot 12 is facing upward, the slider 14 separates from the support foot 12 due to gravity, and the support foot 12 extends into the sleeve 41. The locking block 43 abuts against the end face of the support foot 12 near the slider 14 to achieve connection. When unlocking, the working platform 40 moves downward, driving the locking block 43 to move to the end face of the slider 14 away from the support foot 12. The locking block 43 slides down to the outer circumference of the support foot 12 under the action of the guide slope and releases the lock with the support foot 12.

[0024] The connecting rod 13 is ball-jointed with the support arm 11. When the support foot 12 contacts the ground, because it is conical, the end with the larger diameter faces down, resulting in a larger contact area with the ground, which can improve the stability of the support. When the support arm 11 is folded up, the end with the larger diameter of the support foot 12 faces up, which can be connected to the sleeve 41.

[0025] After the machine stops, the support arm 11 is folded first, followed by the operating arm 30. After the operating arm 30 is folded, the working platform 40 is in a horizontal position at the top. At this time, the working platform 40 is initially positioned above the support arm 11. Once the position is corrected, the working platform 40 can be driven downwards, and the support leg 12 gradually extends into the sleeve 41. Since the size of the inner cavity of the sleeve 41 is adapted to the support leg 12, the support leg 12 can be aligned. Furthermore, the locking block 43 slides along the outer circumference of the support leg 12 to below the end face of the smaller diameter end of the support leg 12, thereby achieving a locking connection with the support leg 12. This improves the overall integrity of the mechanical equipment and prevents the work platform 40 from accidentally starting and rising when the machine is stopped. When unlocking, the work platform 40 is driven down a certain distance. During this process, the top surface of the slider 14 is also provided with a conical surface of varying sizes. This conical surface guides the locking block 43 to the slider 14 away from the end face of the support foot 12. Then, the work platform 40 drives the locking block 43 to move upward. The locking block 43 moves upward and slides along the guide slope on the slider 14 to the outer circumference of the support foot 12, releasing the engagement with the support foot 12 and unlocking the work platform 40.

[0026] This structure enables automatic connection and unlocking of the support leg 12 and the connecting structure. When connected, it prevents the work platform from moving upward, thus improving the integrity and safety of the structure. The unlocking process is convenient and requires no manual intervention, thus improving automation.

[0027] In some embodiments, an improved implementation of the drive platform 20 described above may employ, as follows: Figures 4 to 5 The structure shown. See also Figures 4 to 5 The drive platform 20 includes a first motor 21 mounted on the vehicle body 10, a rotary table 22 connected to the output shaft of the first motor 21, and a limiting mechanism mounted on the vehicle body 10 and located at the bottom of the rotary table 22. The rotary table 22 is provided with a plurality of guide grooves 221 and a cylinder 25 coaxial with the rotary table 22. The limiting mechanism includes a plurality of limiting blocks 23 that slide in cooperation with the guide grooves 221 one by one. A connecting rod 24 is connected between the limiting block 23 and the vehicle body 10. One end of the connecting rod 24 is hinged to the limiting block 23, and the other end of the connecting rod 24 is hinged to the vehicle body 10. When the first motor 21 drives the rotary table 22 to rotate, multiple limit blocks 23 slide in the corresponding guide grooves 221 and gradually come into contact with the outer periphery of the cylinder 25.

[0028] The extension path of the guide groove 221 is arc-shaped, and the center of the arc coincides with the hinge axis of the connecting rod 24 and the vehicle body 10. When the drive platform 20 is rotated, the limiting block 23 rotates with the connecting rod 24 as the radius and moves within the guide groove 221, gradually approaching the cylinder 25. Similarly, when the rotation is reversed, the limiting block 23 gradually approaches the cylinder 25. In this embodiment, when the first motor 21 drives the rotary table 22 to rotate, the limiting block 23 slides within the guide groove 221 and gradually abuts against the outer circumference of the cylinder 25, forming a multi-point uniform limiting. When multiple limiting blocks 23 abut against the cylinder 25, the drive platform 20 can be restricted from continuing to rotate, thereby limiting the rotation angle of the drive platform 20. The hinge structure of the connecting rod 24 makes the sliding trajectory of the limiting block 23 completely match the guide groove 221, ensuring a smooth and impact-free limiting process, reducing mechanical wear, and extending the service life of the equipment.

[0029] In some embodiments, an improved implementation of the above-described operating platform 40 may employ, as follows: Figure 6 and Figure 10 The structure shown. See also Figure 6 and Figure 10 The work platform 40 includes a fixed frame 45, a fixed platform 46 fixed to the fixed frame 45, and a deformable platform 47 rotatably connected to the fixed frame 45. The deformable platform 47 has an unfolded first state and a folded second state. In the first state, the deformable platform 47 is a ladder extending from the fixed frame 45 to the ground. In the second state, the top surface of the deformable platform 47 is flush with the top surface of the fixed platform 46 to form a platform for supporting workers. When workers climb onto or get off the work platform 40, the deformable platform 47 can be unfolded. After unfolding, the deformable platform 47 extends from the outer periphery of the fixed frame 45 to the ground to form a ladder connecting the ground and the work platform 40, facilitating workers' access. After entering the work platform 40, workers stand on the fixed platform 46. The deformable platform 47 is folded and rotated to the inner periphery of the fixed frame 45, forming a platform by connecting with the fixed platform 46, facilitating workers' walking and standing on the work platform 40.

[0030] It should be noted that when the deformable platform 47 is in the second state, the deformable platform 47 and the fixed platform 46 can be fixed together by means of buckles, locks and other structures to ensure the safety of workers on the work platform 40.

[0031] In some embodiments, a specific implementation of the aforementioned deformable platform 47 may employ, as follows: Figure 10 The structure shown. See also Figure 10The deformable platform 47 includes a first frame 471 hinged to the fixed frame 45 and a second frame 472 hinged to the first frame 471. Climbing poles are provided on both the first frame 471 and the second frame 472. A foot pedal 473 is provided on the back of the first frame 471. In the second state, the first frame 471 and the second frame 472 are stacked in the vertical direction, and the foot pedal 473 is connected to and flush with the fixed platform 46. In the first state, the first frame 471 and the second frame 472 are parallel and extend to the ground to form a ladder.

[0032] In this embodiment, the hinged structure of the first frame 471 and the second frame 472 enables the ladder to be flexibly folded and unfolded. The climbing poles provide a stable gripping point for the operator. The foot pedal 473 is flush with the fixed platform 46 to ensure the stability of walking when going up and down the platform. The foot pedal 473 can be made of non-slip material to increase the friction with the sole of the shoe and prevent slipping when climbing, further improving the safety of the operation. In addition, the two-section frame structure allows the deformable platform 47 to adapt to working environments of different heights, making it more practical.

[0033] Specifically, the switching between the first and second states of the deformable platform 47 can be done manually or automatically. When driven by electricity, a drive motor can be installed at the hinge between the first frame 471 and the fixed frame 45, and at the hinge between the first frame 471 and the second frame 472, to reduce labor costs.

[0034] In some embodiments, an improved implementation of the above-described operating platform 40 may employ, as follows: Figure 6 and Figure 10 The structure shown. See also Figure 6 and Figure 10 The work platform 40 is equipped with a safety railing 48, and an openable safety door 49 is provided on the hinged side of the safety railing 48 near the first frame 471 and the fixed frame 45. The safety railing 48 surrounds the work platform 40 to form a protective barrier to prevent workers from accidentally falling while working at height; the openable safety door 49 facilitates workers' entry and exit from the platform, and the door can be locked after being closed to ensure that it will not be accidentally opened during operation; the safety door 49 is located on the hinged side near the first frame 471, corresponding to the position of the ladder, making the path for workers to go up and down the platform more reasonable and facilitating the unfolding and folding operation of the deformable platform 47.

[0035] It should be noted that in embodiments where the safety door 49 and the slide rail 410 are installed together, the slide rail 410 may not be installed on the side where the safety door 49 is located.

[0036] In some embodiments, an improved implementation of the above-described operating platform 40 may employ, as follows: Figure 1 and Figure 6 The structure shown. See also Figure 1 and Figure 6 An adjustment mechanism 60 is fixedly mounted on the working platform 40. The adjustment mechanism 60 includes a first linear module 61 extending along the Y direction, a second linear module 62 slidably engaged with the first linear module 61 and extending along the X direction, and a mounting bracket 63 slidably engaged with the second linear module 62. The wire clamp 50 is fixedly mounted on the mounting bracket 63. The first linear module 61 and the second linear module 62 form a two-dimensional moving platform, enabling precise movement of the wire clamp 50 in the XY plane. The positioning accuracy is high, and it can quickly connect to wires at different positions, replacing manual adjustment and improving work efficiency. Both the first linear module 61 and the second linear module 62 can be driven by servo motors, which have fast response speed and smooth operation. They can automatically adjust according to the position of the wire, reducing manual operation errors and avoiding wire damage or work failure due to position deviation.

[0037] In some embodiments, an improved implementation of the above-described operating platform 40 may employ, as follows: Figure 7 The structure shown. See also Figure 7 The outer periphery of the working platform 40 is provided with an annular slide rail 410 and a fixed rod 411 connecting the slide rail 410 and the working platform 40. The adjustment mechanism 60 also includes an adjustment block 64, which is slidably connected to the slide rail 410. The first linear module 61 is fixed on the adjustment block 64. The back of the first linear module 61 is provided with an upper clamping block 65 and a lower clamping block 66. The opposite surfaces of the upper clamping block 65 and the lower clamping block 66 are provided with grooves 67. The adjusting block 64 is a ring structure and is rotatably fitted at the groove 67. The side wall of the adjusting block 64 is provided with an opening. When the opening of the adjusting block 64 faces upward or downward, the upper clamping block 65 or the lower clamping block 66 covers the opening. When the opening of the adjusting block 64 faces away from the first linear module 61, the fixing rod 411 can pass through the opening. The cooperation between the annular slide rail 410 and the adjusting block 64 allows the adjusting mechanism 60 to rotate circumferentially around the working platform 40, expanding the working range of the wire clamp 50. It can achieve wire clamping in different positions without rotating the entire operating arm 30, reducing energy consumption and improving operational flexibility. The opening design of the adjusting block 64 allows the adjusting mechanism 60 to avoid the fixed rod 411, enabling the adjusting block 64 to move circumferentially along the slide rail 410 without any dead angles. The covering effect of the upper clamping block 65 and the lower clamping block 66 on the opening ensures the structural stability of the adjusting mechanism 60 during operation and prevents the adjusting block 64 from accidentally shifting.

[0038] In some embodiments, a specific implementation of the mounting bracket 63 described above can be as follows: Figure 9 The structure shown. See also Figure 9The mounting bracket 63 includes a movable seat 631 that slides into the second linear module 62, a U-shaped frame 632 hinged to the movable seat 631, a tripod 633 hinged to the U-shaped frame 632, and a wire clamp 50 hinged to the tripod 633. The axial direction of the hinge axis between the movable seat 631 and the U-shaped frame 632 is defined as the first axial direction, the axial direction of the hinge axis between the U-shaped frame 632 and the tripod 633 is defined as the second axial direction, and the axial direction of the hinge axis between the tripod 633 and the wire clamp 50 is defined as the third axial direction. The first axial direction is perpendicular to the second axial direction, and the second axial direction is parallel to the third axial direction. The three-section hinged structure of the mounting bracket 63, combined with the perpendicularity of the first and second axes and the parallelism of the second and third axes, gives the wire clamp 50 three-dimensional rotational freedom, which can adapt to different placement angles and postures of the lead wire, ensuring the stability and reliability of the clamping. The multi-degree-of-freedom adjustment allows the wire clamp 50 to accurately fit the lead wire surface, avoiding excessive local pressure that could damage the lead wire insulation layer. At the same time, the angle of the lead wire can be adjusted according to the disassembly and reassembly requirements, making it convenient for operators to perform screw disassembly and reassembly operations.

[0039] Specifically, there are connecting structures between the tripod 633 and the U-shaped frame 632, between the U-shaped frame 632 and the movable seat 631, and between the tripod 633 and the wire clamp 50. The connecting structures are bolts and nuts. The bolts form the aforementioned hinge shaft. When the nuts are loosened, rotation can be performed. When the nuts are tightened, the current position is fixed. The structure is simple and the operation is easy.

[0040] In some embodiments, a specific implementation of the wire clamp 50 may employ, as follows: Figure 8 The structure shown. See also Figure 8 The wire clamp 50 includes a first clamping part 51, a second clamping part 52 hinged to the first clamping part 51, and an adjusting piece 53 slidably engaged with the second clamping part 52. A compression spring 54 is also provided between the adjusting piece 53 and the second clamping part 52. The adjusting piece 53 is located between the first clamping part 51 and the second clamping part 52 and is used to move in a direction close to or away from the first clamping part 51. The adjusting piece 53 has a V-shaped structure with its opening facing the first clamping part 51 and is used to cooperate with the first clamping part 51 to clamp the lead wire. The V-shaped adjusting block 64 cooperates with the first clamping part 51 to accommodate lead wires of different diameters. The pre-tightening force provided by the compression spring 54 can automatically adjust the clamping force according to the lead wire diameter, ensuring a firm clamping without damaging the lead wire. The sliding design of the adjusting plate 53 makes the clamping process more flexible, allowing for quick clamping and loosening of the lead wire. Combined with the moving and rotating functions of the wire clamp 50, it provides full-process assistance for lead wire splicing and disconnection, eliminating the need for manual intervention and reducing labor costs and workload.

[0041] In some embodiments, a specific implementation of the above-described manipulator 30 may employ, as follows: Figure 1 The structure shown. See also Figure 1 The manipulator 30 is equipped with a permanent magnet synchronous servo motor between two adjacent segments, and it has an electromagnetic brake. When the power is off, the output shaft can be locked to prevent it from sagging due to gravity. The hinge shaft between two adjacent segments is defined as the joint shaft. The specific power transmission route is servo motor output shaft, planetary reducer, drive gear, driven gear, joint shaft. The controller realizes multi-axis (joint shaft) control of the manipulator 30. Each joint shaft is equipped with an encoder to collect rotation angle information, a torque sensor is installed on the manipulator 30 to obtain load information, and an tilt sensor is installed on the work platform 40 to obtain horizontal information. It is equipped with an interface for connecting servo drivers, a structure for connecting sensors, an interface for connecting remote controllers, and a communication interface to ensure real-time control of motors and real-time data transmission. In addition, the operator can also input coordinate values ​​in the controller, and the controller (PLC) automatically calculates the required rotation angle of each motor and adjusts it.

[0042] To facilitate observation of the working status of the wire clamp 50, a remote monitoring system is also provided on the mounting bracket 63. The remote monitoring system can be a network camera. After the wire clamp 50 clamps and fixes the lead wire, the camera can capture the working image of the wire clamp 50 and transmit it to the ground personnel's handheld tablet, computer or mobile phone, etc., so as to make it easy to judge the clamping status of the wire clamp 50. The camera can use WIFI, Bluetooth or other modules to achieve wireless transmission, and can also have built-in storage devices (hard disk, cloud disk, etc.) to store the image for easy playback to prevent missing important images.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
