[0001] This invention relates to the field of power equipment maintenance technology, specifically to a portable auxiliary device for disassembling, assembling, and transporting current transformers in switchgear. Background Technology

[0002] With the rapid development of power systems, the maintenance and repair of switchgear, as a key piece of equipment in power distribution networks, has become increasingly important. Current transformers, as a core component of switchgear, require frequent disassembly, assembly, and relocation for routine calibration and fault replacement.

[0003] However, due to the fact that this component is usually heavy, has a narrow installation space, and requires high alignment accuracy, the traditional manual operation mode has significant efficiency bottlenecks, safety risks, and operational inconveniences. Operators need to perform high-intensity load-bearing and precise alignment in a limited cabinet space, which is not only labor-intensive and time-consuming, but also prone to equipment collisions, personnel injuries, or subsequent operational hazards due to obstructed vision, improper force, or improper installation. This invention proposes a new solution to the above problems. Summary of the Invention

The frame includes a fixed section and a movable section rotatably connected. A telescopic arm is connected to the movable section. The clamping mechanism is disposed on the telescopic arm and is used to grip and fix the current transformer. The telescopic drive mechanism is disposed on the fixed section of the frame and its output end is connected to the telescopic arm, used to drive the telescopic arm to extend and retract. The horizontal position of the clamping mechanism is adjusted. The lifting drive mechanism is mounted on the fixed section of the frame and its output end is connected to the moving section. It is used to drive the moving section to lift and adjust the vertical position of the clamping mechanism. The camera is mounted on the telescopic arm and moves with the clamping mechanism. The field of view of the camera is facing the current transformer installation position and is used to capture the image of the installation position. The operation display mechanism is communicatively connected to the telescopic drive mechanism, the lifting drive mechanism and the camera, and is used to receive control commands from the operator, drive the telescopic drive mechanism and / or the lifting drive mechanism to operate, and display the image captured by the camera.

[0005] In one possible implementation, the base mechanism includes a base, casters, and support legs. The casters are disposed at the bottom of the base to assist movement, and the support legs are disposed on both sides of the base and extend outward to assist support.

[0006] In one possible implementation, the rotating assembly includes a turntable and a fixing pin. The turntable includes a rotating seat and a rotating bearing.

[0007] In one possible implementation, the fixed section and the moving section of the frame are hinged to enable rotation of the moving section.

[0008] In one possible implementation, the telescopic drive mechanism includes a telescopic electric pump station and a telescopic arm, a portion of which is embedded within the moving section, and the telescopic electric pump station provides power for the extension and retraction of the telescopic arm.

[0009] In one possible implementation, the lifting drive mechanism includes a lifting electric pump station and a balance link assembly.

The lifting electric pump station provides power for the lifting of the moving section.

[0010] In one embodiment, the clamping mechanism includes a hanging plate and a rotating connector. The hanging plate has mounting holes for connecting to a current transformer. The end of the telescopic arm is rotatably connected to the hanging plate through the rotating connector for adjusting the clamping angle.

[0011] In one possible implementation, the operation display mechanism includes a control box and a hand grip, the hand grip being used to assist the operator in holding and operating the device.

[0012] In one possible implementation, the control box includes a battery module, a drive module, and an operation panel. The battery module provides power to the device, the drive module drives the telescopic drive mechanism and / or the lifting drive mechanism, and the operation panel is used by the operator to input control commands and view the device status.

[0013] In one possible implementation, the camera is a high-definition camera capable of transmitting images of the installation station to the operation display mechanism in real time.

[0014] The beneficial technical effects of this invention are as follows: According to this disclosure, the portable switchgear current transformer disassembly and assembly auxiliary device provides a stable foundation support for the device with its base mechanism, ensuring stability during movement and operation.

[0020] This application provides a portable auxiliary device for disassembling, assembling, and transporting current transformers in switchgear, such as... Figures 1-4 As shown, the device includes a base mechanism 1, a frame 2, a rotating assembly 3, a telescopic drive mechanism 4, a lifting drive mechanism 5, a clamping mechanism 6, a camera mechanism 7, and an operation display mechanism 8. The frame 2 is rotatably connected to the base mechanism 1 via the rotating assembly 3, which is used to adjust the rotation angle of the frame 2. The frame 2 includes a fixed section 21 and a moving section 22 that are rotatably connected. A telescopic arm 42 is connected to the moving section 22. The clamping mechanism 6 is mounted on the telescopic arm 42 and is used to grip and fix the current transformer. The telescopic drive mechanism 4 is mounted on the fixed section 21 of the frame 2 and its output end is connected to the telescopic arm 42, which is used to drive the telescopic arm 42 to extend and retract to adjust the clamping position. The horizontal position of mechanism 6, the lifting drive mechanism 5 is set on the fixed section 21 of frame 2 and its output end is connected to the moving section 22, used to drive the moving section 22 to lift and adjust the vertical position of clamping mechanism 6, the camera mechanism 7 is set on telescopic arm 42 and moves with clamping mechanism 6, the field of view of camera mechanism 7 is facing the current transformer installation position, used to capture the image of the installation position, the operation display mechanism 8 is communicatively connected to telescopic drive mechanism 4, lifting drive mechanism 5 and camera mechanism 7, used to receive control commands from the operator, drive telescopic drive mechanism 4 and / or lifting drive mechanism 5 to act, and display the image captured by camera mechanism 7.

[0021] The portable switchgear current transformer disassembly and assembly auxiliary device provided in this embodiment has a base mechanism 1 that provides a stable foundation for the device, ensuring stability during movement and operation. Combined with the rotating component 3, it enables multi-angle horizontal rotation of the frame 2, flexibly adapting to complex working spaces around the switchgear. It can cover disassembly and assembly needs in different locations without frequent device relocation. The fixed section 21 and the moving section 22 of the frame 2 are rotatably connected. Combined with the lifting drive mechanism 5 controlling the lifting of the moving section 22, the operating height range of the clamping mechanism 6 can be significantly expanded. Whether in low spaces or at higher positions, the device can be precisely adjusted to a suitable working posture for current transformer disassembly and assembly. The telescopic drive mechanism 4 drives... The telescopic arm 42 extends and retracts, driving the clamping mechanism 6 to achieve precise horizontal displacement. In conjunction with the clamping mechanism 6, the current transformer is reliably gripped and fixed, allowing it to be smoothly transferred to the installation position. This effectively avoids potential bumps and damage during manual handling. The camera mechanism 7 moves synchronously with the clamping mechanism 6 and captures real-time images of the installation position. Operators can intuitively grasp the position status through the operation display mechanism 8 and precisely control each drive mechanism to adjust the position of the current transformer, significantly improving installation accuracy and work efficiency. The overall structure is compact and highly integrated, with smooth transitions between the actions of each mechanism. This reduces the labor intensity of operators while ensuring the safety and stability of the current transformer disassembly, assembly, and transportation process.

[0022] In one possible implementation, such as Figures 1-4 As shown, the base mechanism 1 includes a base 11, casters 12 and legs 13. The casters 12 are located at the bottom of the base 11 to assist movement, and the legs 13 are located on both sides of the base 11 and extend outward to assist support.

[0023] The casters 12 are located at the bottom of the base 11, allowing operators to easily move the device between different work areas without expending a lot of physical effort. This improves the device's response speed and working range. Whether in a narrow power distribution room passage or an open outdoor area, the casters 12 can roll smoothly, effectively reducing the labor and time costs during the device transfer process. This allows the device to quickly reach the designated work location and meet the current transformer disassembly and assembly needs in different scenarios.

[0024] The support legs 13 are located on both sides of the base 11 and extend outwards, further expanding the support range of the device and forming a wider support surface. When the device reaches the working position, the support legs 13 are lowered to improve the stability of the device and avoid the risk of swaying or tipping during operations such as grasping, moving, and installing the current transformer. The outward-extending design of the support legs 13 makes full use of the space in the working area, firmly locking the center of gravity of the device within the support surface range. Even in the face of changes in the weight of the current transformer or external interference, the device can maintain a stable state, providing a reliable foundation for high-precision operations.

[0025] In one possible implementation, such as Figure 1 and Figure 2 As shown, the rotating assembly 3 includes a turntable 31 and a fixing pin 32. The turntable 31 includes a rotating seat 62 and a rotating bearing. The rotating seat 62 is fixedly connected to the base mechanism 1, and the frame 2 is connected to the rotating bearing. The fixing pin 32 is used for the relative position of the base mechanism 1 and the turntable 31.

[0026] The turntable 31 consists of a rotating seat 62 and a rotating bearing. The rotating seat 62 is fixedly connected to the base mechanism 1, providing a stable foundation for the entire rotating assembly 3. The rotating bearing enables the frame 2 to rotate smoothly around the base mechanism 1, effectively expanding the operating coverage of the device.

[0027] Corresponding holes are made on the turntable 31 and the base. After the frame 2 rotates to the specified angle, the fixing pin 32 is embedded in the corresponding hole. The setting of the fixing pin 32 ensures the positional stability of the frame 2 after it is rotated into place, and prevents the frame 2 from shifting due to vibration or external force during operation, thus ensuring the accuracy of the current transformer grabbing, transfer and installation.

[0028] Understandably, the combination of turntable 31 and fixed pin 32 achieves both flexibility in rotation and reliability in positioning, enabling the device to quickly adjust its posture and stably complete various disassembly and assembly tasks in complex working environments.

[0029] In one possible implementation, such as Figure 1 and Figure 2 As shown, the fixed section 21 and the moving section 22 of the frame 2 are hinged together to enable the rotation of the moving section 22.

[0030] Among them, the fixed section 21 and the moving section 22 of the frame 2 adopt a hinged design, which allows the moving section 22 to adjust the rotation angle according to the operation requirements, thereby realizing the lifting and lowering of the clamping mechanism 6. Whether facing the narrow installation space inside the switch cabinet or the differentiated layout of different models of switch cabinets, the clamping mechanism 6 can be accurately aligned with the gripping or installation position of the current transformer by rotating the moving section 22, which greatly improves the adaptability of the device to complex operating environments.

[0031] In one possible implementation, such as Figure 1 and Figure 2 As shown, the telescopic drive mechanism 4 includes a telescopic electric pump station 41 and a telescopic arm 42. A portion of the telescopic arm 42 is embedded in the moving section 22, and the telescopic electric pump station 41 provides power for the extension and retraction of the telescopic arm 42.

[0032] The telescopic drive mechanism 4, through the telescopic electric pump station 41 and the telescopic arm 42, enables precise adjustment of the horizontal position of the clamping mechanism 6, providing flexible and efficient horizontal displacement support for the disassembly and assembly of the current transformer in the switchgear. During operation, the telescopic electric pump station 41 provides stable power to the telescopic arm 42, driving the arm to extend or retract smoothly, and moving the clamping mechanism 6 precisely to the designated position. Whether grabbing the current transformer inside the switchgear or moving it to the installation station, precise positioning can be achieved, which not only improves the accuracy and efficiency of the operation, but also avoids the positional deviation that may occur during manual handling, providing a reliable guarantee for the safe disassembly and assembly of the current transformer.

[0033] Understandably, the structural design of the telescopic arm 42 with the fixed section 21 embedded in the moving section 22 ensures the stability of the telescopic arm 42 during the telescopic process, while also effectively saving space and making the overall structure of the device more compact.

[0034] In one possible implementation, such as Figure 1 and Figure 2 As shown, the lifting drive mechanism 5 includes a lifting electric pump station 51 and a balance link 52 assembly. The balance link 52 assembly includes a balance link 52, a balance beam 53, and a balance plate mounting seat 54. The balance plate mounting seat 54 is mounted on the moving section 22. The first end of the balance plate mounting seat 54 is hinged to the first end of the balance beam 53, the second end of the balance beam 53 is hinged to the fixed section 21, the second end of the balance plate mounting seat 54 is hinged to the balance link 52, and the second end of the balance link 52 is hinged to the fixed section 21 or hinged to the fixed section 21 via an L-shaped plate. The lifting electric pump station 51 provides power for the lifting of the moving section 22.

[0035] Among them, the lifting drive mechanism 5 provides stable power for the lifting of the moving section 22 through the lifting electric pump station 51. The coordinated design of the balance link 52, the balance beam 53 and the balance plate mounting seat 54 provides stable and precise structural support for the lifting of the moving section 22, which not only improves the load-bearing capacity of the device, but also enhances the stability during operation.

[0036] The balance plate mounting base 54 is hinged to a balance beam 53 at one end and a balance link 52 at the other end. Combined with the hinges of the balance beam 53 and balance link 52 to the fixed section 21, a multi-link balance link 52 assembly is formed. Driven by the electric lifting pump station 51, the moving section 22 can achieve smooth lifting and lowering. The multi-link structure effectively distributes the load during the lifting process, preventing the moving section 22 from tilting or swaying, and ensuring the vertical displacement accuracy of the clamping mechanism 6.

[0037] Among them, the balance link 52 assembly adopts a symmetrical layout on both sides of the frame 2, which achieves balanced load distribution from a structural mechanics perspective. During the lifting and lowering process of the moving section 22, the links on both sides are subjected to force synchronously with the beam, effectively avoiding structural tilting or stress concentration problems caused by unilateral force.

[0038] Among them, the shape-fitting design of the balance link 52 assembly with the fixed section 21 and the moving section 22 greatly improves the space utilization of the device. Especially in space-constrained operation scenarios such as switch cabinets, the fitted layout allows the lifting drive mechanism 5 to be closely attached to the frame 2 structure, reducing unnecessary space occupation. The overall structure of the device is more compact, and the clamping mechanism 6 can also reach into the narrow area inside the switch cabinet to complete the disassembly and assembly of the current transformer, which is difficult for traditional devices to access, significantly expanding the operating range of the device.

[0039] Furthermore, the second end of the balance link 52 can be designed with either direct hinge to the fixed section 21 or hinged via an L-shaped plate, enhancing the adaptability of the lifting drive mechanism 5 to different scenarios. The direct hinge design is structurally simple and allows for efficient connection between the balance link 52 and the fixed section 21 in environments with ample space, reducing errors and losses from intermediate components, ensuring direct force transmission during lifting, and improving the mechanism's response speed. The L-shaped plate hinge design provides a feasible solution for space-constrained operating scenarios. The L-shaped plate can change the direction of force transmission, allowing the balance link 52 to complete power transmission without direct contact with the fixed section 21. The shape of the L-shaped plate better fits the junction between the fixed section 21 and the moving end, effectively avoiding spatial conflicts between the various structures of the device, resulting in a more compact layout.

[0040] In one possible implementation, such as Figures 1-4 As shown, the clamping mechanism 6 includes a hanging plate 61 and a rotating connector. The hanging plate 61 is provided with a mounting hole 611 for connecting to a current transformer. The end of the telescopic arm 42 is rotatably connected to the hanging plate 61 through the rotating connector for adjusting the clamping angle.

[0041] The mounting holes 611 on the hanging plate 61 can be precisely connected to the current transformer, ensuring the reliability of the connection. The rotating connector allows the telescopic arm 42 and the hanging plate 61 to form a rotatable connection, which can freely adjust the clamping angle and adapt to different installation scenarios and operation requirements, effectively improving the flexibility and adaptability of operation.

[0042] The rotating connector supports both manual and automatic adjustment modes, allowing for flexible selection based on actual working conditions. Manual adjustment involves manually operating the locking device of the rotating connector, loosening it to adjust the angle between the hanging plate 61 and the telescopic arm 42, and then re-locking it once in place. This simple and low-cost design is suitable for scenarios where the working posture does not change frequently. Operators can visually confirm the angle position to ensure stable clamping. Automatic adjustment integrates an electric or hydraulic drive unit, along with an angle sensor and control system, to achieve precise and remote control of the clamping angle. In complex or high-precision operations, it can be linked with other drive mechanisms to improve overall automation and work efficiency, reducing human error.

[0043] In one possible implementation, such as Figures 1-4 As shown, the operation display mechanism 8 includes a control box 81 and a hand grip 82, which is used to assist the operator in holding and operating the device.

[0044] The handgrip 82 is ergonomically designed to effectively reduce fatigue during prolonged operation and improve operational stability. The control box 81 integrates core control and display functions, ensuring the accuracy of operation command input. The two handgrips 82 are located on both sides of the control box 81, optimizing the overall portability and allowing operators to easily complete various operation tasks.

[0045] In one possible implementation, such as Figure 2 As shown, the control box 81 includes a battery module 811, a drive module 812, and an operation panel 813. The battery module 811 is used to provide power to the device, the drive module 812 is used to drive the telescopic drive mechanism 4 and / or the lifting drive mechanism 5, and the operation panel 813 is used by the operator to input control commands and view the status of the device.

[0046] Among them, the battery module 811 provides stable power support for the entire device, ensuring the continuous operation of each mechanism. The drive module 812 precisely connects to the telescopic drive mechanism 4 and the lifting drive mechanism 5. The operation panel 813 integrates command input and status viewing functions. Its compact and reasonable layout allows operators to intuitively control the operation of the equipment. The compact integration improves space utilization and ease of operation.

[0047] In one possible implementation, such as Figures 1-4 As shown, camera mechanism 7 is a high-definition camera that can transmit the image of the installation station to the operation display mechanism 8 in real time.

[0048] The camera mechanism 7 employs a high-definition camera with real-time image acquisition and transmission capabilities, clearly and stably transmitting the work footage from the installation station to the display screen of the operation display mechanism 8. Through high frame rate and low latency video transmission, the camera mechanism 7 allows operators to remotely and accurately grasp on-site details, improving the visibility of the work and operational safety. The integration of the camera structure with the operation display mechanism 8 enhances the human-machine interface experience, effectively reducing operational risks and improving construction accuracy and response efficiency, especially in complex or hazardous conditions.
