[0023] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0024] According to the appendix Figure 1 , 2 As shown: This utility model provides a robotic arm for operating switchgear: it includes a multi-joint robotic arm 1, which is mounted on a hydraulic lifting platform using an AGV chassis. The multi-joint robotic arm 1 is bolted to the top of the hydraulic lifting platform. The end of the multi-joint robotic arm 1 is provided with an operating component 2 for operating the switchgear. Specifically, the AGV chassis, hydraulic lifting platform and multi-joint robotic arm all adopt existing known technologies, which will not be described in detail here. The AGV chassis autonomously navigates to the target switchgear location based on path planning or remote commands. The hydraulic lifting platform adjusts the working height of the robotic arm to adapt to the height differences of the operating interface of different switchgear models. The multi-joint robotic arm 1 moves flexibly through multiple joints to accurately position the operating component to the operating surface of the switchgear.
[0025] As per the instruction manual Figure 1 , 3As shown: The operating component 2 includes a pneumatic slip ring 3 fixedly mounted at the end of the multi-joint robotic arm 1. A cross plate 4 is provided at the end of the pneumatic slip ring 3. A longitudinal groove 5 is formed at the bottom of the cross plate 4. A T-shaped clamping plate 6, slidably connected to the groove 5, is symmetrically provided below the bottom of the cross plate 4. Pneumatic push rods 7, symmetrically provided on both sides of the top of the cross plate 4 for driving the T-shaped clamping plate 6, are provided. Limiting rails 15, matching the side walls of the T-shaped clamping plate 6, are symmetrically provided on both sides of the groove 5, serving to limit the movement of the T-shaped clamping plate 6. A vertical plate 16 is provided at the telescopic end of the pneumatic push rod 7. The vertical plate 16 is connected to... Connecting rods 17 are fixedly connected between the side walls of the T-shaped clamping plates 6 that are close to each other. Specifically, the T-shaped clamping plates 6 are flexibly adjusted to a suitable position by the multi-joint robotic arm 1. The pneumatic push rods 7 on both sides are activated to drive the vertical plate 16 and the connecting rod 17 to move, thereby driving the T-shaped clamping plates 6 on both sides to move closer to each other. Thus, the T-shaped clamping plates 6 on both sides can clamp the emergency trip button of the switchgear. The air slip ring 3 is activated to drive the cross plate 4 to rotate, thereby driving the T-shaped clamping plates 6 to rotate, which can realize the turning action of the clamped emergency trip button of the switchgear, thus facilitating the opening and closing operation.
[0026] As per the instruction manual Figure 1 , 4 As shown: The top horizontal side of the cross plate 4 is provided with a key part 8 for pressing the control button of the switch cabinet. The key part 8 includes a pneumatic push rod 2 10 fixedly installed on the top horizontal side of the cross plate 4. The telescopic rod end of the pneumatic push rod 2 10 is fixedly connected to the key rod 11. Specifically, the key rod 11 is flexibly adjusted to a suitable position by the multi-joint robotic arm 1, and the pneumatic push rod 2 10 is activated to drive the key rod 11 to press the control button.
[0027] As per the instruction manual Figure 4 As shown: The top of the cross plate 4 is provided with an unlocking part 9 on the other side for emergency screwing and unlocking of the switch cabinet. The unlocking part 9 includes a pneumatic motor 12 fixedly installed on the top of the cross plate 4. The output end of the pneumatic motor 12 is fixedly connected to an unlocking sleeve 13. Specifically, the unlocking sleeve 13 is flexibly adjusted to a suitable position by the multi-joint robotic arm 1 so that the unlocking sleeve 13 is inserted into the emergency screwing of the corresponding switch cabinet. Starting the pneumatic motor 12 drives the unlocking sleeve 13 to rotate, which can unlock the switch cabinet in an emergency screwing.
[0028] As per the instruction manual Figure 1 As shown: an air pump and an air compressor installed on the hydraulic lifting platform are used to supply air to the air slip ring 3. The corresponding soft air supply tube is tied along the multi-joint robotic arm 1. The top of the air tube cross plate 4 is equipped with pneumatic solenoid valves 14 on both the horizontal and vertical sides, which are located outside the air slip ring 3. Each pneumatic solenoid valve 14 is connected to the air slip ring 3 and the corresponding pneumatic motor 12, pneumatic push rod 1 7, and pneumatic push rod 2 10 through the air tube. The pneumatic solenoid valves 14 are used to centrally control the action sequence of each pneumatic component.
[0029] This robotic arm employs an advanced control system that integrates motion control, sensor data processing, and human-machine interaction functions. Users can input operation commands via a touchscreen or remote computer terminal. The control system then calculates the robotic arm's motion trajectory and the end effector's operation mode based on these commands and algorithms, achieving automated operation. The operating component 2 executes clamping, pressing, or rotating operations according to the commands, completing the automated operation of the entire switchgear. The control circuit can be easily programmed by those skilled in the art, and the power supply is also common knowledge in the field. Furthermore, since this invention primarily protects mechanical devices, the control method and circuit connections will not be explained in detail here.
[0030] The principle of this utility model
[0031] In use, the multi-joint robotic arm 1 uses flexible multi-joint movement to precisely position the operating component 2 onto the switchgear operating surface. The operating component 2 performs opening and closing operations, emergency unlocking by turning, and key control, offering richer functionality and easily completing substation switching functions, significantly improving usability: For key operation, the pneumatic push rod 10 drives the key lever 11 to press the control button; for emergency unlocking, the pneumatic motor 12 drives the unlocking sleeve 13 to rotate the knob; for emergency unlocking of the switchgear, the pneumatic push rod 7 pushes the T-shaped clamping plate 6 through the connecting rod 17, sliding along the slide groove 5 and the limit rail 15 to clamp the switchgear emergency opening button. The air slip ring 3 then rotates the T-shaped clamping plate 6, realizing the turning action of the clamped switchgear emergency opening button, thus conveniently achieving opening and closing operations.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
