[0002] In the power system, the generator output circuit breaker operating mechanism is crucial to ensuring the safe and stable operation of the generator. When the generator output circuit breaker (GCB) operating mechanism fails, the staff needs to dismantle and replace it. In actual disassembly and assembly conditions, some types of generator output circuit breakers (GCB) have large structural dimensions and mass. Although there is no wireless slot structure in the disassembly and assembly space, the tail space is small. Manual disassembly and assembly of the operating mechanism often requires maintenance personnel to perform long-term, high-intensity physical labor in a small space, which increases the difficulty and fatigue of the work and makes it difficult to ensure the quality of disassembly and assembly. In addition, the process of manually finding the connection points, disassembly and installation is time-consuming and has low work efficiency. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Due to the large size and mass of the generator circuit breaker (GCB) operating mechanism during disassembly and assembly, there is no wireless slot structure in the disassembly and assembly space, but the tail space is small, so the generator circuit breaker (GCB) operating mechanism needs to be supported during disassembly and assembly;

[0028] The utility model provides a retractable auxiliary disassembly and assembly device for the operating mechanism of the generator output circuit breaker, such as Figures 1 to 4 As shown, it includes a sleeve frame 1, a telescopic frame 2, a front bracket 3, a rear bracket 4, a roller 5, a rolling drive device 6, a lifting drive device 7, an omnidirectional drive wheel set 8, a support wheel 9 and a battery 10;

[0029] Specifically, if Figure 1 As shown, the telescopic frame 2 is U-shaped as a whole, and two sleeves are provided on the sleeve frame 1 corresponding to the two support rods of the telescopic frame 2, and the support rods of the telescopic frame 2 are correspondingly slidably sleeved in the sleeve of the sleeve frame 1; the front bracket 3 is vertically slidably mounted on the telescopic frame 2, and is driven to slide by a lifting drive device 7, and the lifting drive device 7 adopts two electric push rods respectively provided on both sides of the front bracket 3, the electric push rods are fixedly mounted on the telescopic frame 2, and the telescopic ends thereof are fixedly connected to the front bracket 3; the rear bracket 4 is vertically slidably mounted on the sleeve frame 1, and is driven to slide by the lifting drive device 7, the lifting drive device 7 adopts two electric push rods respectively provided on both sides of the rear bracket 4, the electric push rods are fixedly mounted on the sleeve frame 1, and the telescopic ends thereof are fixedly connected to the rear bracket 4;

[0030] In one embodiment, Figure 1 and Figure 2 As shown, the upper end surfaces of the front bracket 3 and the rear bracket 4 are both arc-shaped, and are rotatably mounted with four rollers 5. The axes of the four rollers 5 are distributed in an arc shape. The rolling drive device 6 adopts a servo motor and is fixedly mounted on the rear bracket 4. The output end thereof is coaxially fixedly connected to a roller 5 located on the edge of the rear bracket 4.

[0031] In one embodiment, Figure 3 As shown, two sets of omnidirectional drive wheel groups 8 are installed on the bottom surface of the sleeve frame 1, and one set of omnidirectional drive wheel groups 8 is installed on the bottom surface of the telescopic frame 2. The omnidirectional drive wheel groups 8 use steering wheels. Each set of steering wheels adopts a dual-motor drive method consisting of an azimuth motor and a roll motor. Through motion control instructions, three degrees of freedom of motion can be achieved in the plane, namely, movement in the plane X and Y directions and rotation around the Z axis. The details are as follows:

[0032] When the azimuth motors control the steering direction to 0°, all the roll motors are controlled to rotate in the same direction and speed, so that the sleeve frame 1 and the telescopic frame 2 can be moved horizontally;

[0033] When the azimuth motors control the steering to 90 degrees, all the roll motors are controlled to rotate in the same direction and speed, so that the sleeve frame 1 and the telescopic frame 2 can be moved longitudinally;

[0034] When the azimuth motors control the direction of rotation to α°, all the roll motors are controlled to rotate in the same direction and speed, so that the sleeve frame 1 and the telescopic frame 2 can be moved obliquely. The angle between the oblique direction and the X-axis is α°.

[0035] When the azimuth motors control the steering direction to point to the geometric center of the sleeve frame 1 and the telescopic frame 2 as a whole, all the rolling motors are controlled to rotate at a specific speed, so that the sleeve frame 1 and the telescopic frame 2 can rotate around the geometric center as a whole;

[0036] Furthermore, support wheels 9 are rotatably mounted on both sides of the omnidirectional drive wheel set 8 on the telescopic frame 2 to support the telescopic frame 2, and the battery 10 is fixedly mounted on the sleeve frame 1;

[0037] In one embodiment, an operating system is further included, which includes a main controller, an information transmission module, and a power module. The main controller is electrically connected to the information transmission module and the power module to control the operation of the entire multi-axis adaptive auxiliary disassembly and assembly device. The information transmission module is electrically connected to the rolling drive device 6, the lifting drive device 7, and the omnidirectional drive wheel set 8. The power module is electrically connected to the battery 10 to supply power to other electrical components.

[0038] In one embodiment, disassembling the device works as follows:

[0039] 1. Dismantle the operating mechanism of the generator output circuit breaker

[0040] Step S1: The operator controls the omnidirectional drive wheel set 8 through the operating system to move the entire retractable auxiliary disassembly and assembly device to the position directly below the operating mechanism of the generator circuit breaker (GCB) to be disassembled;

[0041] Step S2: The operator pulls the telescopic frame 2 outward and adjusts the distance between the front bracket 3 and the rear bracket 4 according to the actual span of the generator circuit breaker (GCB) operating mechanism;

[0042] Step S3: Start the lifting drive device 7, and the front bracket 3 and the rear bracket 4 rise and support the generator output circuit breaker (GCB) operating mechanism;

[0043] Step S4: The operator disassembles the generator circuit breaker (GCB) operating mechanism. After disassembly, the generator circuit breaker (GCB) operating mechanism falls onto the front bracket 3 and the rear bracket 4. The lifting drive device 7 is activated, and the front bracket 3 and the rear bracket 4 are lowered. The omnidirectional drive wheel set 8 drives the entire retractable auxiliary disassembly and assembly device to move outward.

[0044] 2. Install the operating mechanism of the generator output circuit breaker:

[0045] Step S1: The operator pulls the telescopic frame 2 outward and adjusts the distance between the front bracket 3 and the rear bracket 4 according to the actual span of the generator circuit breaker (GCB) operating mechanism to be installed; then, the generator circuit breaker (GCB) operating mechanism to be installed is placed on the front bracket 3 and the rear bracket 4;

[0046] Step S2: The operator controls the omnidirectional drive wheel set 8 through the operating system to move the entire retractable auxiliary disassembly and assembly device to the position directly below the installation location of the generator output circuit breaker (GCB) operating mechanism;

[0047] Step S3: Start the lifting drive device 7, and the front bracket 3 and the rear bracket 4 rise, driving the connector of the generator circuit breaker (GCB) operating mechanism to rise to a height roughly flush with the installation location; then start the rolling drive device 6, driving the roller 5 connected thereto to rotate, thereby driving the generator circuit breaker (GCB) operating mechanism to rotate, so that the screw hole of the generator circuit breaker (GCB) operating mechanism is aligned with the installation hole;

[0048] Step S4: After the screw holes are aligned with the mounting holes, the omnidirectional drive wheel assembly 8 drives the entire retractable auxiliary disassembly and assembly device to move toward the installation location, so that the screw holes are aligned with the mounting holes; then the operator begins the installation work; after the installation is completed, the lifting drive device 7 drives the front bracket 3 and the rear bracket 4 to descend, and the generator circuit breaker (GCB) operating mechanism is separated from the front bracket 3 and the rear bracket 4, and finally the retractable auxiliary disassembly and assembly device is withdrawn;

[0049] In one embodiment, a sensor connected to the operating system is further included. The sensor is an industrial image processing sensor, which serves as an end-positioning and detection unit to assist in aligning the screw holes of the generator circuit breaker operating mechanism with the mounting holes. When the sensor is actually in operation, it needs to be fixedly mounted on the generator circuit breaker operating mechanism to be adjusted so as to collect image information of the mounting holes in real time.

[0050] Specifically, when installing the generator circuit breaker operating mechanism, the sensor is fixedly installed on the center of the generator output circuit breaker (GCB) operating mechanism connector; after the generator output circuit breaker (GCB) operating mechanism connector rises to a height roughly flush with the installation location, the sensor will collect image information of the installation hole in real time and transmit the image information to the main controller, which processes the image information and calculates whether the position and posture of the generator circuit breaker operating mechanism to be installed are greater than the alignment error; if greater than the alignment error, the main controller transmits an electrical signal to the information transmission module, adjusts the position of the generator output circuit breaker (GCB) operating mechanism to be installed by controlling the lifting drive device 7 and the omnidirectional drive wheel group 8, and drives the generator output circuit breaker (GCB) operating mechanism to be installed to rotate around the central axis by controlling the rolling drive device 6, thereby adjusting the posture, and then collects image information again and performs posture calculation until the posture is less than the alignment error, that is, the screw hole on the generator output circuit breaker (GCB) operating mechanism is aligned with the mounting hole;
