[0046] See also Figure 1 , an embodiment of a circuit breaker maintenance chassis device provided in the embodiments of the present application includes:

[0047] The chassis body 1, the secondary wiring mechanism 4, the first limiting mechanism and the second limiting mechanism.

[0050] The secondary wiring mechanism 4 is mounted on the chassis body 1 .

[0051] It can be seen from the above technical solutions that the present application designs a first limiting mechanism and a second limiting mechanism on the chassis body 1, wherein the second limiting mechanism is arranged in the first clamping limiting space formed by the first limiting mechanism, that is, the chassis body 1 has limiting spaces of different sizes, and the relatively large first limiting space can be used to limit and fix the circuit breaker with a chassis, while the relatively small second limiting space can be used to limit and fix the circuit breaker without a chassis, which is more convenient to use, and the first limiting space and the second limiting space are both designed to be adjustable, so that they can adapt to the limiting and fixing of circuit breakers of more sizes. Furthermore, the secondary wiring mechanism 4 is also combined with the chassis body 1, so that the secondary wiring is more convenient, which can be applied to automated maintenance operations, realize automated secondary wiring, and further reduce the labor intensity of the operation. The chassis device of the present application solves the technical problems that the current maintenance chassis device has a single functionality and is insufficient in use.

[0052] The above is the first embodiment of a circuit breaker maintenance chassis device provided by the embodiment of the present application. The following is the second embodiment of a circuit breaker maintenance chassis device provided by the embodiment of the present application. For details, please refer to Figure 1 to Figure 2 .

[0053] Based on the solution of the above embodiment 1:

[0054] Furthermore, as for the structural composition of the first clamping mechanism 2, it includes a first clamping member 21, a first sliding mechanism 22 and a locking mechanism 23. The first clamping member 21 is slidably mounted on the chassis body 1 through the first sliding mechanism 22; the locking mechanism 23 is used to lock the first clamping member 21 after the first clamping member 21 slides a preset displacement, and the sliding operation of the first clamping member 21 can be a manual sliding adjustment. When adjusted to the right position, the first clamping member 21 can be locked by operating the locking mechanism 23. In the present application, the first clamping member 21 can be a long block structure, and the inner side surface of the first clamping member 21, that is, the side of the first clamping member 21 facing the other first clamping member 21, can be provided with a slide groove arranged along its own length direction for the moving wheel of the chassis of the circuit breaker to be inserted, and there is no specific limitation.

[0055] Furthermore, the first sliding mechanism 22 includes a linear guide rail 221 and a slider 222. The linear guide rail 221 is mounted on the chassis body 1. The slider 222 is mounted on the bottom of the first clamping member 21 and slides with the linear guide rail 221. The slider 222 can be an HGH slider without limitation.

[0056] Furthermore, as for the structural composition of the locking mechanism 23, it includes a mounting seat 231 and a positioning rod 232; a plurality of positioning holes 10 are arranged in an array along the sliding direction of the first clamping member 21 on the chassis body 1; the mounting seat 231 is fixed to the first clamping member 21; the positioning rod 232 is movably inserted into the mounting seat 231 along the vertical direction, and one end of the positioning rod 232 extending downward from the mounting seat 231 can be movably inserted into the corresponding positioning hole 10. The distance between two adjacent positioning holes 10 is a single adjustable displacement, and this distance can be designed according to actual needs without limitation. In addition, the locking mechanism 23 can be multiple, and the corresponding positioning holes 10 can be multiple rows. The increase in the number can improve the reliability of the limit fixation to a certain extent, but it will also increase the amount of operation. The appropriate number can be selected according to actual needs. The push rod can be a pin, a screw, a bolt, etc. Before sliding adjustment, lift the positioning rod 232 or rotate the positioning rod 232 so that the positioning rod 232 withdraws from the corresponding positioning hole 10. After the sliding adjustment is in place, release the positioning rod 232 or rotate the positioning rod 232 again so that the positioning rod 232 extends into the corresponding positioning hole 10 to achieve locking and fixation of the first clamping member 21.

[0057] Further, in order to facilitate the switching of different adjustment intervals, a detachable positioning block 11 can be provided on the chassis body 1, and the positioning hole 10 is opened on the positioning block 11. Then, if a different adjustment displacement is to be changed, the positioning block 11 can be directly replaced, which is more convenient to use.

[0058] Furthermore, the second clamping mechanism 3 includes a second clamping member 31, a second sliding mechanism 33 and a driving member; the second clamping member 31 is slidably mounted on the chassis body 1 through the second sliding mechanism 33; the driving member is connected to the second clamping member 31 and is used to drive the second clamping member 31 to move, that is, the sliding displacement of the second clamping member 31 is directly adjusted by the driving member. The structural design of the second clamping member 31 can be as follows: Figure 1 as well as Figure 2 The U-shape shown is not specifically limited.

[0059] Furthermore, the second sliding mechanism 33 includes a first fixed block 331, a second fixed block 332 and a guide rod 333. The first fixed block 331 and the second fixed block 332 are installed on the chassis body 1 at intervals. The guide rod 333 is installed between the first fixed block 331 and the second fixed block 332. The second clamping member 31 is provided with a guide hole for the guide rod 333 to move through. In order to make the sliding fit between the guide rod 333 and the second clamping member 31 smoother and not to wear the second clamping member 31, a bushing 311 that slides with the guide rod 333 can be provided on the guide hole. The bushing 311 can be oil-free and is not limited. In addition, the number of guide rods 333 can be multiple, which further improves the reliability of sliding fit.

[0060] Furthermore, in terms of the structural composition of the driving member, it includes a screw 32 and a nut. The screw 32 is pivotally fixed to the first fixed block 331; the nut is embedded in the second clamping member 31 and is passed through by the screw 32. The screw 32 is pivotally fixed to the first fixed block 331, and is axially limited, and can only be rotated. In this way, when the screw 32 is rotated, the sliding displacement of the second clamping member 31 can be adjusted by threaded engagement. The second clamping member 31 is configured to be only slidable but not rotatable, ensuring that the rotational motion can be smoothly converted into linear motion. For details, please refer to the existing principle of rotation-linear motion mechanism, and no further description will be given.

[0061] Furthermore, the secondary wiring mechanism 4 includes a docking quick plug and an aviation plug. After the circuit breaker is positioned, the aviation plug is connected to the circuit breaker, and then the quick plug can be automatically docked through the assembly line to complete the power-on action, thereby improving the convenience of secondary wiring and further improving the detection efficiency.

[0062] Furthermore, in order to facilitate transportation, reduce labor intensity, and improve operation safety, a transportation hoisting member 5 is also included, and the transportation hoisting member 5 is installed on the chassis body 1. There can be multiple transportation hoisting members 5, which are evenly distributed on the chassis body 1. Specifically, they can be square flange bearings, and their bearing holes can form connection holes for hoisting, which are convenient for connection and fixation before transportation.

[0063] The above is a detailed introduction to a circuit breaker maintenance chassis device provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
