Description

Technical Field

[0001] This invention relates to the field of online operation technology, and in particular to a wire lifting device and a high-altitude wire lifting method for online operations. Background Technology

[0002] When performing live-line work such as connecting live wires or connecting drop wires on overhead lines, clamps (such as S-clamps and parallel groove clamps) are typically used to reliably connect the drop wire to the energized overhead conductor. Before completing such live-line work, a section of insulation must be precisely stripped from the conductor at a predetermined location to expose the internal wire core, so that the clamp can be used for subsequent electrical connection. Currently, live-line work in distribution networks mainly involves connecting drop wires to corresponding cables, which is a crucial step in ensuring the normal operation of the power system.

[0003] However, current online wiring and connection operations are still predominantly done manually, requiring workers to strip cables and connect them while the power is on. This manual live-line work method is not only inefficient but also poses significant safety risks, seriously threatening the lives of workers. There is an urgent need for a technological solution that can replace manual labor and achieve automated online operations. Summary of the Invention

[0004] In order to address the technical deficiencies mentioned in the background section, the present invention aims to provide a wire lifting device and a high-altitude wire lifting method for online operations, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wire lifting device for online operations includes: A swing mechanism for providing a swing degree of freedom about a first direction; A translation mechanism, installed at the output end of the swing mechanism, is used to provide linear translational freedom along the second direction; A fixed base is connected to the output end of the translation mechanism; A movable seat is used to support the object to be lifted and can be detachably docked with the fixed seat; A traction rope is used to pull the movable seat to one side of the fixed seat and connect it with the fixed seat.

[0006] Specifically, the swing mechanism includes: Oscillating driver; A swing frame is connected to the output end of the swing driver and swings around the first direction under the drive of the swing driver; The translation mechanism is mounted on the swing frame.

[0007] Specifically, the wire lifting device further includes: A winding reel is rotatably mounted on the swing frame; One end of the traction rope is connected to the movable seat, and the other end of the traction rope passes through the fixed seat and is wound up by the winding wheel.

[0008] Specifically, the other end of the traction rope is pulled manually; or The winding reel is driven by an electric drive mounted on the swing frame to achieve winding.

[0009] Specifically, the movable seat is provided with a clamp slot for accommodating the clamp and a locking device for locking the clamp.

[0010] Specifically, the movable seat is provided with a clamping head, which includes: Two clamping parts that can open and close relative to each other are used to clamp or release the core of the drain wire; A driving component is used to drive the two clamping components to open and close.

[0011] Specifically, the cable lifting device further includes an angle adjustment mechanism, which includes: A rotary actuator is located at the output end of the translation mechanism; A conical disk is connected to the output end of the rotary driver and can rotate around a second direction. A limiting protrusion is provided on the inner side of the conical disk. A conical head is connected to one end of the movable seat and cooperates with the conical disc. The conical head is provided with multiple limiting slots that are adapted to the limiting protrusion. The rotary driver drives the movable seat to rotate to a predetermined angle around the second direction through the cooperation of the conical disk and the conical head.

[0012] Specifically, a camera is provided on the output end of the translation mechanism, and the camera's shooting direction is towards one side of the movable seat.

[0013] Specifically, the wire lifting device further includes a docking detection and locking module, which includes: The photodetector's sensing optical path is configured such that when the fixed base and the movable base are aligned, light simultaneously passes through the preset through holes on both. A telescopic locking component is used to simultaneously pass through the preset locking holes on the fixed seat and the movable seat after docking is completed, so as to lock the two together.

[0014] A high-altitude guy wire lifting method, applied to the guy wire lifting device, includes the following steps: The object to be lifted is loaded onto the movable seat; The movable seat is pulled from a low position to a high position by the traction rope until it is connected with the fixed seat; The spatial position of the fixed seat and the movable seat docked thereon is adjusted by the swing mechanism and / or the translation mechanism so that the object to be lifted reaches the target working position.

[0015] Beneficial effects: This application utilizes a traction rope to pull a movable seat loaded with the object to be lifted from a lower position to a higher position until the movable seat aligns with a fixed seat. Then, a swing mechanism and / or a translation mechanism adjust the spatial position of the fixed seat and the movable seat it aligns with, ensuring the object is precisely positioned at the target work location. The entire process achieves automated transport and precise positioning of the object from the ground to the high-altitude work point, eliminating the need for manual climbing to heights for handling and adjustment. This fundamentally eliminates the safety hazards of falls from heights and electric shocks, significantly improving work efficiency, safety, and consistency. It can be widely applied to online work scenarios such as live-line connections and drain wire splicing. Attached Figure Description

Detailed Implementation

[0018] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0019] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0021] In this application, unless otherwise expressly specified and limited, the terms “installation,” “connection,” “linking,” “fixing,” etc., shall be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral part; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; they may refer to the internal connection of two components or the interaction between two components, unless otherwise expressly limited.

[0022] Example 1 Please combine Figures 1 to 9 As shown, this embodiment discloses a wire lifting device for online operations. The device can be installed on an online operation platform 90, which travels on a high-altitude conductor 91 for live-line contact operations. The wire lifting device includes a swing mechanism 10, a translation mechanism 20, a fixed base 30, a movable base 40, and a traction rope 50.

[0023] The swing mechanism 10 has a swing driver 11 mounted on one side of the online work platform 90, providing a swing degree of freedom about a first direction. A translation mechanism 20 is mounted at the output end of the swing mechanism 10, providing a linear translation degree of freedom along a second direction. A fixed base 30 is connected to the output end of the translation mechanism 20. A movable base 40 carries the wire clamp 71 and is detachably docked with the fixed base 30. A traction rope 50 pulls the movable base 40 from a lower position to one side of the fixed base 30, docking it with the fixed base 30. The movable base 40 has a wire clamp groove 41 for accommodating the wire clamp 71 and a locking device 42 for locking the wire clamp 71.

[0024] It should be noted that, due to the variety of types of wire clamps 71, including common types such as S-type wire clamps and parallel groove wire clamps, different types of wire clamps differ in their external dimensions and structures. Therefore, the shape of the wire clamp groove 41 is not uniquely fixed. In practical applications, the wire clamp groove 41 can be adaptively designed according to the specific model of the wire clamp 71 to be clamped. For example, for S-type wire clamps, it can be designed as a contoured groove that matches its external outline, while for parallel groove wire clamps, it can be designed as a groove structure with corresponding clamping space. In addition, the structure of the locking device 42 can also be adjusted accordingly according to the type of wire clamp 71 to ensure reliable locking of different types of wire clamps 71. Those skilled in the art should understand that any wire clamp groove structure that can accommodate and lock the wire clamp to be lifted should be considered within the scope of this application.

[0025] Specifically, during live-line connection work, the wire clamp 71 is first placed in the wire clamp slot 41 of the movable seat 40 and reliably locked by the locking device 42 to prevent displacement or detachment during lifting. Then, the movable seat 40 is gradually pulled from the ground or lower level to a higher altitude using the traction rope 50 until it is docked with the fixed seat 30. After docking, the overall spatial position of the fixed seat 30 and the docked movable seat 40 is adjusted by the swinging motion of the swing mechanism 10 and / or the translating motion of the translation mechanism 20, ensuring that the wire clamp 71 accurately reaches the target working position so that other actuators on the online work platform 90 can subsequently complete the connection work. This structure achieves automated high-altitude lifting and precise positioning of the wire clamp 71, effectively avoiding the safety risks associated with manual live-line high-altitude work and significantly improving work efficiency and consistency.

[0026] Of course, the above-mentioned method of adjusting by combining the swing mechanism 10 and the translation mechanism 20 is only a preferred implementation. In other embodiments, the swing mechanism 10 or the translation mechanism 20 may be used for adjustment only according to the actual working conditions, as long as the movable seat 40 and the wire clamp 71 on it can be delivered to the target position. These variations should be considered within the scope of protection of this application.

[0027] like Figure 4 As shown, the swing mechanism 10 includes a swing driver 11 and a swing frame 12. The swing driver 11 can be a drive motor or a motor gear set, and its body is fixed to one side of the online work platform 90. The swing frame 12 is connected to the output end of the swing driver 11 and swings around a first direction under the drive of the swing driver 11. The translation mechanism 20 is integrally mounted on the swing frame 12 and swings together with the swing frame 12.

[0028] During operation, if the position of the wire clamp 71 deviates horizontally after the movable seat 40 and the fixed seat 30 are connected, the swing driver 11 can drive the swing frame 12 to swing around the first direction, thereby causing the entire translation mechanism 20, the fixed seat 30, and the movable seat 40 to swing together, thus adjusting the posture of the wire clamp 71 in the swing plane. This swing adjustment action allows the wire clamp 71 to be finely adjusted within a wide range to adapt to different wire routes and connection point positions, greatly improving the applicability and flexibility of the device.

[0029] like Figure 4As shown, the translation mechanism 20 includes two parallel guide rails 21 fixed to the swing frame 12 and extending along a second direction, a slider 22 sliding along the guide rails 21, a right-angle motor 23 fixed to the swing frame 12, a lead screw 24 drivenly connected to the output shaft of the right-angle motor 23, a lead screw sleeve 25 fixed to the slider 22, and a support frame 26 fixed to the slider 22. The lead screw sleeve 25 is threadedly engaged with the lead screw 24, the support frame 26 serves as the output end of the translation mechanism 20, and the fixed seat 30 is fixed to the support frame 26.

[0030] During operation, when the position of the wire clamp 71 needs to be adjusted in the second direction, the right-angle motor 23 drives the lead screw 24 to rotate. The lead screw 24, through its threaded engagement with the lead screw sleeve 25, converts the rotational motion into the linear motion of the slider 22 along the guide rail 21, thereby driving the support frame 26 and the fixed seat 30 to move in the second direction, achieving precise positioning of the wire clamp 71 in the linear direction. This translation mechanism 20 adopts a lead screw and nut transmission method, which has the advantages of high positioning accuracy, smooth movement, and good self-locking, ensuring that the wire clamp 71 remains stable during adjustment and avoiding positioning deviations caused by vibration or inertia.

[0031] like Figure 4 As shown, a camera 63 is installed on the output end of the translation mechanism 20, with the camera 63 pointing towards the movable seat 40. The camera 63 is used to acquire real-time image information of the movable seat 40 and the cable clamp 71, and transmit the image data to the control system of the ground control terminal or the online work platform 90. Operators can remotely monitor the lifting process of the movable seat 40, its docking status with the fixed seat 30, and the posture of the cable clamp 71 through the images transmitted from the camera 63, thereby enabling auxiliary judgment and remote control. The camera 63 significantly improves the intuitiveness and safety of operation, and is especially suitable for precision operations in complex high-altitude environments.

[0032] Of course, the above-mentioned driving method using a right-angle motor 23 in conjunction with a lead screw 24 is only a preferred embodiment. In other embodiments, other linear drive elements such as linear motors, hydraulic cylinders, or pneumatic cylinders can also be used to achieve the translation function, as long as smooth linear motion along the second direction can be achieved. These variations should all be considered within the scope of protection of this application.

[0033] like Figure 4 As shown, the cable lifting device also includes a take-up reel 61 and an electric drive 62. The electric drive 62 is mounted on the swing frame 12 and can be a drive motor, with its drive shaft connected to the take-up reel 61. The take-up reel 61 is rotatably mounted on the swing frame 12. One end of the traction rope 50 is connected to the movable seat 40, and the other end of the traction rope 50 passes through the fixed seat 30 and is wound up by the take-up reel 61. The take-up reel 61 is driven by the electric drive 62 to achieve winding.

[0034] At the start of the operation, the movable seat 40 is at its lowest position, and the traction rope 50 is slack. The electric actuator 62 is activated, driving the winding wheel 61 to rotate and gradually winding up the traction rope 50. The traction rope 50 passes through the central clearance hole of the fixed seat 30, pulling the movable seat 40 upwards at a uniform and stable speed. When the movable seat 40 rises to contact and dock with the fixed seat 30, the electric actuator 62 stops, and the traction rope 50 remains taut, ensuring a reliable fit between the movable seat 40 and the fixed seat 30. The winding process, driven by the electric actuator 62 and the winding wheel 61, automates and precisely controls the traction process, avoiding the instability and labor intensity of manual rope pulling.

[0035] like Figures 5 to 8 As shown, the cable lifting device also includes an angle adjustment mechanism 80, which includes a rotary driver 81, a conical disc 82, and a conical head 83. The rotary driver 81 is located at the output end of the translation mechanism 20, i.e., on the support frame 26. The conical disc 82 is connected to the output end of the rotary driver 81 and can rotate around the second direction. A limiting protrusion 821 is provided on the inner side of the conical disc 82. The conical head 83 is connected to one end of the movable seat 40 and cooperates with the conical disc 82. The conical head 83 is provided with multiple limiting slots 831 that are adapted to the limiting protrusions 821. The rotary driver 81 drives the conical disc 82 to rotate through the driving wheel 812, the transmission belt 814, and the driven wheel 813 at its output end. The conical disc 82 engages with the limiting slots 831 on the conical head 83 through the limiting protrusions 821 on its inner side, thereby driving the movable seat 40 to rotate around the second direction to a predetermined angle.

[0036] During the process of the movable seat 40 being pulled to dock with the fixed seat 30, due to the flexibility of the traction rope 50 and the influence of high-altitude wind, the movable seat 40 may twist or deflect to a certain extent, resulting in inconsistent orientation of the first screw of the wire clamp 71, which makes subsequent gripping difficult. To solve this problem, after the movable seat 40 initially contacts the fixed seat 30, the rotary driver 81 drives the conical disk 82 to rotate slowly. The limiting protrusion 821 on the inner side of the conical disk 82 engages with the limiting slot 831 on the conical head 83, causing the movable seat 40 to rotate together. By controlling the rotation angle of the rotary driver 81, the movable seat 40 and the wire clamp 71 on it can be precisely adjusted to the preset circumferential angle, ensuring that the first screw of the wire clamp 71 is uniformly and fixed, which greatly facilitates the rapid and accurate alignment and gripping of the subsequent gripping mechanism on the online work platform 90.

[0037] Of course, the above-mentioned angle adjustment method using the conical disc 82 and conical head 83 is only a preferred embodiment. In other embodiments, other methods such as gear meshing, spline connection or electromagnetic adsorption can also be used to achieve the angle adjustment of the movable seat 40, as long as accurate circumferential positioning can be achieved. These variations should all be considered within the scope of protection of this application.

[0038] like Figures 7 to 8 As shown, the cable lifting device also includes a docking detection and locking module 64, which includes a photoelectric detector 641 and a telescopic locking component 642. The sensing light path of the photoelectric detector 641 is configured so that when the fixed seat 30 and the movable seat 40 are docked in place, the light can pass through the preset through holes 31 on both. The telescopic locking component 642 can be an electromagnet-driven telescopic pin or a miniature electric push rod, used to pass through the preset locking holes 32 on both the fixed seat 30 and the movable seat 40 simultaneously after docking, so as to achieve mechanical locking between the two.

[0039] The specific working process is as follows: During the upward traction of the movable seat 40, the photoelectric detector 641 continuously emits sensing light. As the movable seat 40 gradually approaches and finally fits into place with the fixed seat 30, the through hole 31 on the fixed seat 30 aligns with the through hole 31 on the movable seat 40. The sensing light from the photoelectric detector 641 simultaneously passes through both through holes 31 and is received by the receiving end, thereby generating an electrical signal indicating that the movable seat 40 and the fixed seat 30 have been docked. Upon receiving this signal, the control system immediately controls the electric drive 62 to stop winding and simultaneously controls the telescopic locking member 642 to extend. Its telescopic pin passes through the locking hole 32 of the fixed seat 30 and inserts into the locking hole 32 of the movable seat 40, rigidly locking the two together to prevent relative displacement or separation during subsequent swinging or translational adjustments. This docking detection and locking module 64 ensures the reliability and accuracy of the docking process, providing a solid foundation for subsequent attitude adjustments and operations.

[0040] like Figures 7 to 8 As shown, both the fixed seat 30 and the movable seat 40 are circular plate structures. Circular plate structures offer good symmetry and centering, facilitating circumferential alignment through rotation during docking. Furthermore, the circular structure provides a more uniform stress distribution under load, reducing stress concentration and improving structural strength and durability. Additionally, circular plate structures are easy to manufacture and have lower costs.

[0041] like Figures 7 to 8As shown, both the fixed seat 30 and the movable seat 40 are provided with clearance holes 33 for the guide rail 21 and the lead screw 24 to pass through, in order to prevent translational interference. When the translation mechanism 20 drives the fixed seat 30 to move in the second direction, the guide rail 21 and the lead screw 24 will move accordingly. The clearance holes 33 provide sufficient space for these moving parts, preventing the fixed seat 30 or the movable seat 40 from colliding or rubbing against the guide rail 21 and the lead screw 24, thus ensuring the smoothness and reliability of the translational movement.

[0042] like Figure 4 As shown, the swing frame 12 is equipped with an inlet rope winding wheel 65 and an outlet rope winding wheel 66, which are located on opposite sides above the take-up wheel 61. The swing frame 12 is also equipped with a cover 67 for covering the take-up wheel 61. One end of the cover 67 is rotatably connected to the swing frame 12 via a rotating seat and a rotating shaft, and the other end is locked to the swing frame 12 via a latch.

[0043] The rope inlet sheave 65 and rope outlet sheave 66 guide the direction of the traction rope 50, allowing it to smoothly enter from the fixed base 30 and pass around the take-up reel 61, preventing the traction rope 50 from tangling or deviating during winding. The cover 67 provides protection, preventing external dust and debris from entering the take-up reel 61 area and affecting the normal operation of the winding mechanism. Furthermore, during operation, the cover 67 effectively prevents operators or other objects from accidentally contacting the rotating take-up reel 61, improving safety. The rotating connection via the rotating base and shaft allows the cover 67 to be easily opened for maintenance, repair, or replacement of the traction rope 50 on the take-up reel 61. The locking connection via the latch ensures that the cover 67 remains securely closed during normal operation and will not open automatically due to vibration or wind.

[0044] like Figure 5 As shown, the conical disc 82 has a hollow structure formed by a central section running along the second direction, allowing the traction rope 50 to pass through it. This design cleverly avoids interference between the traction rope 50 and the conical disc 82. Since the traction rope 50 needs to start from the movable seat 40, pass through the fixed seat 30, and finally reach the winding reel 61, and the conical disc 82 is located between the movable seat 40 and the fixed seat 30, a solid structure would inevitably obstruct the path of the traction rope 50. By designing the conical disc 82 to have a central section running through it, the traction rope 50 can pass through unimpeded, without affecting the angle adjustment function of the conical disc 82 on the movable seat 40 or the normal winding and unwinding of the traction rope 50, achieving seamless integration of the two functions.

[0045] like Figure 5As shown, the rotary drive 81 includes a drive motor 811 fixed on the support frame 26, a drive wheel 812 connected to the output shaft of the drive motor 811, a driven wheel 813 sleeved on the outside of the conical disc 82, and a transmission belt 814 connecting the drive wheel 812 and the driven wheel 813.

[0046] The main reason for using this belt drive structure instead of directly connecting the drive motor 811 to the conical disc 82 coaxially is that if the drive motor 811 were directly mounted on the axis of the conical disc 82, the motor body would occupy the space in the middle of the conical disc 82, thus blocking the path of the traction rope 50 through the conical disc 82. However, through the transmission method of the driving pulley 812, driven pulley 813, and transmission belt 814, the drive motor 811 can be arranged on one side of the conical disc 82, keeping the middle of the conical disc 82 unobstructed, allowing the traction rope 50 to pass smoothly. At the same time, belt drives also have advantages such as shock absorption, smooth operation, and overload protection, making them suitable for the vibration and impact environment of high-altitude operations.

[0047] This embodiment also discloses a high-altitude guy wire lifting method, which is applied to the above-mentioned guy wire lifting device and includes the following steps: The first step is to load the wire clamp 71 onto the wire clamp slot 41 of the movable seat 40 and lock it in place using the locking device 42.

[0048] The second step involves using the traction rope 50 to pull the movable seat 40 from a low position to a high position until the movable seat 40 and the fixed seat 30 are docked. The docking detection and locking module 64 then confirms and locks the docking.

[0049] The third step is to adjust the spatial position of the fixed seat 30 and the movable seat 40 connected thereon by the swing mechanism 10 and / or the translation mechanism 20 so that the wire clamp 71 reaches the target working position.

[0050] This method achieves fully automated transport and precise positioning of the wire clamp 71 from the ground to the high-altitude work point through automated traction, docking, and multi-degree-of-freedom attitude adjustment. It eliminates the need for manual climbing to high altitudes to move and adjust the clamp, fundamentally eliminating the safety hazards of falls and electric shocks. Furthermore, the method features a clear process and smooth integration, allowing seamless cooperation with other online work mechanisms (such as wire stripping and wiring mechanisms) to form a complete automated live-line connection operation process, significantly improving work efficiency and quality.

[0051] Example 2 The main difference between this embodiment and Embodiment 1 lies in the traction method.

[0052] Please refer to Figure 10As shown, in this embodiment, the take-up reel 61 is not driven, i.e., no electric drive unit 62 is provided. One end of the traction rope 50 is connected to the movable seat 40, and the other end of the traction rope 50 goes around the take-up reel 61 and hangs directly to the ground. During operation, the worker stands on the ground and manually pulls the hanging end of the traction rope 50. The traction rope 50 slides on the take-up reel 61, thereby driving the movable seat 40 to gradually rise from a low position to a high position until the movable seat 40 is connected to the fixed seat 30.

[0053] The movable base 40 is also provided with a clamp slot 41 for accommodating the clamp 71 and a locking device 42. After the movable base 40 is docked with the fixed base 30, the gripping mechanism on the online work platform 90 can grab the clamp 71 from the movable base 40 and hang it on the conductor 91 for subsequent live-line connection work.

[0054] This embodiment provides a manual traction solution. Although its automation level is not as high as the electric traction solution in Embodiment 1, its structure is simpler, its cost is lower, and it does not rely on a power supply, making it suitable for some temporary or simple work scenarios. Workers can control the speed and force of the rope pull to flexibly manage the lifting process of the movable seat 40, achieving the goal of safely and accurately lifting the line clamp 71 to a high altitude. The winding wheel 61 serves as a guide and reduces friction, making manual rope pulling more effortless and smoother.

[0055] Of course, the above-mentioned method of manually pulling the traction rope 50 is only a preferred embodiment. In other embodiments, manual winding tools such as hand-cranked winches can be used instead of directly pulling the rope to achieve a more labor-saving and controllable traction operation. These variations should all be considered within the scope of protection of this application.

[0056] Example 3 The main difference between this embodiment and embodiment 1 lies in the type of object carried on the movable seat 40 and its corresponding clamping structure.

[0057] Please refer to Figure 11 As shown, the pull-line lifting device disclosed in this embodiment is mainly used for performing drain line splicing operations. Therefore, the movable base 40 no longer has a clamp slot 41 and a locking device 42 for accommodating the clamp 71, but instead has a clamping head 43. The clamping head 43 includes two clamping members 431 and a driving member 432 for driving the two clamping members 431 to open and close. The two clamping members 431 can open and close relative to each other to clamp or release the core of the drain line 72.

[0058] The driving element 432 can be a combination of a spring and a wedge block, or it can be a driving element such as a miniature electric push rod or a pneumatic finger. In one specific implementation, the driving element 432 includes a torsion spring sleeved on a cylindrical pin and an inclined guide surface connected to the clamping element 431. When the opening and closing clamp 43 slides in a specific direction, the inclined guide surface interacts with the wedge block on the sliding seat, forcing the two clamping elements 431 to come together, thereby clamping the core of the drain line 72. When the opening and closing clamp 43 slides in the opposite direction, the wedge block releases the constraint on the inclined guide surface, and the torsion spring releases the torque to separate the clamping elements 431, thereby releasing the drain line 72.

[0059] During the connection of the drain line, the core of the drain line 72 is first placed between the two clamping members 431. Then, the two clamping members 431 are closed by the driving member 432 to reliably clamp the core of the drain line 72. Subsequently, the movable seat 40 is lifted to a high position by the traction rope 50 and connected to the fixed seat 30. Then, the position of the movable seat 40 is adjusted by the swing mechanism 10 and / or the translation mechanism 20 so that the core of the drain line 72 accurately reaches the predetermined connection point on the conductor 91, so that the connection mechanism on the online working platform 90 can complete the connection operation between the drain line 72 and the conductor 91.

[0060] By setting the opening and closing clamp 43, the wire lifting device of this embodiment can be used for clamping and lifting the lead wire, expanding the application range of the device. It can be used not only for conveying the wire clamp 71, but also for the direct clamping and positioning of the lead wire 72, providing a flexible solution for different types of live-line contact operations.

[0061] Of course, the above-described method of using the opening and closing clamp 43 to hold the drainage line 72 is only a preferred embodiment. In other embodiments, elastic claws, magnetic clamps or other forms of clamping structures can also be used to hold the drainage line 72, as long as reliable clamping and release can be achieved. These variations should all be considered within the scope of protection of this application.

[0062] The above-described embodiments are merely illustrative of several specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
