[0024] The first moving assembly 2 and the second moving assembly 3 are used to drive the vacuum circuit breaker to move, and when the first moving assembly 2 moves, the second moving assembly 3 is driven to move in the opposite direction of the first moving assembly 2 by the transmission member 4, and in the initial state, the height of the second moving assembly 3 is lower than that of the first moving assembly 2.

[0025] When replacing the circuit breaker in the switch cabinet, the new circuit breaker is placed on the second moving assembly 3, and the old circuit breaker is disassembled and placed on the first moving assembly 2, and then the first moving assembly 2 is pushed to move in the direction of the second moving assembly 3, at this time, the second moving assembly 3 drives the new circuit breaker to move in the direction of the first moving assembly 2 under the action of the transmission member 4, and also drives the new circuit breaker to rise in height, and finally the first moving assembly 2 and the second moving assembly 3 change positions, and the second moving assembly 3 rises to the height of the first moving assembly 2, at this time, the new circuit breaker can be sent to the installation position for installation, so that the time for transporting the new and old circuit breakers back and forth can be saved, thereby improving the installation efficiency of the circuit breaker.

[0026] As an optional embodiment, how to improve the installation efficiency of the circuit breaker is specifically described.

[0027] The transporting assembly 1 includes a transporting vehicle 11, a guide member 12 arranged at the middle position of the bottom of the transporting vehicle 11, and a support frame 13 arranged at one side of the bottom of the transporting vehicle 11, wherein the transporting vehicle 11 is in a box shape, and directional wheels are installed at the bottom, support frames 13 are installed at both sides of the inner wall of the box-shaped structure, the support frames 13 are plate blocks with an S-shaped cross section, and sliding rails are installed at the top and middle parts of the support frames 13, the transmission member 4 is installed at the middle part of the support frame 13 and is parallel to the sliding rail at the middle part of the support frame 13, and the guide member 12 is installed at the middle position of the bottom of the box-shaped structure and is located between the two support frames 13.

[0028] The first moving assembly 2 comprises a first connecting plate 21 and a first supporting block 22 arranged at the bottom of the first connecting plate 21, wherein the first connecting plate 21 is a rectangular plate, and other instruments for assisting the disassembly and assembly of the circuit breaker can be installed on the first connecting plate 21.

[0029] The top of the supporting frame 13 is slidably connected with the bottom of the first supporting block 22, and the first connecting plate 21 can slide along the top of the transport vehicle 11, wherein the bottom of the first connecting plate 21 is provided with the C-shaped first supporting block 22 through bolts, and a sliding groove capable of being clamped with a sliding rail is arranged at the top of the first supporting block 22, and the sliding groove is slidably connected with the sliding rail arranged at the top of the supporting frame 13.

[0030] The second moving assembly 3 comprises a second connecting plate 31, a sliding rod 32 arranged at the bottom of the second connecting plate 31, a moving plate 33 slidably connected with the outer wall of the sliding rod 32, and a second supporting block 34 arranged at the bottom of the moving plate 33, wherein the second connecting plate 31 is a rectangular plate, the length of which is smaller than that of the first connecting plate 21, the moving plate 33 is also a rectangular plate, the area of which is smaller than that of the second connecting plate 31, the moving plate 33 is arranged at the bottom of the second connecting plate 31, and the sliding rod 32 is an L-shaped rod, the vertical part of which penetrates the moving plate 33.

[0031] The bottom of the second supporting block 34 is slidably connected with the top of the supporting frame 13, the sliding rod 32 is perpendicular to the moving plate 33, and the sliding rod 32 can slide relative to the moving plate 33, wherein two symmetrical second supporting blocks 34 are arranged at the bottom of the moving plate 33 through bolts, and the bottom of the second supporting block 34 is also provided with a sliding groove capable of being clamped with a sliding rail, and the bottom of the second supporting block 34 is slidably connected with the sliding rail arranged in the middle of the supporting frame 13.

[0032] The guide 12 comprises a rectangular block 121 arranged at the bottom of the transport vehicle 11, a downward groove 122 arranged at the bottom of the rectangular block 121, and an upward groove 123 arranged at the top of the rectangular block 121, the downward groove 122 is communicated with the upward groove 123, the bottom of the sliding rod 32 is slidably connected with the inner wall of the downward groove 122, and the sliding rod 32 can slide along the downward groove 122 to the upward groove 123, wherein the rectangular block 121 is arranged at the bottom of the transport vehicle 11 through bolts, the downward groove 122 and the upward groove 123 are communicated through an inclined chute, the bottom of the sliding rod 32 is slidably connected with the downward groove 122, when the sliding rod 32 moves along the downward groove 122 to the direction of the first connecting plate 21, the sliding rod 32 will pass through the inclined chute, the inclined chute will lift the height of the sliding rod 32, so that the second connecting plate 31 rises, and when the sliding rod 32 slides from the inclined chute to the upward groove 123, the second connecting plate 31 will rise to the height of the first connecting plate 21.

[0033] In summary, when replacing an old circuit breaker with a new one, the new circuit breaker is placed on the second connecting plate 31, and the old circuit breaker is removed and placed on the first connecting plate 21. The first connecting plate 21 is pushed towards the second connecting plate 31. During the movement of the first connecting plate 21 and the first support block 22, the transmission component 4 will rotate. The transmission component 4 will drive the moving plate 33 and the second support block 34 to move towards the first connecting plate 21. At the same time, the moving plate 33 will drive the second connecting plate 31 and the sliding rod 32 to move. The sliding rod 32 will slide along the downward groove 122 towards the inclined groove and the upward groove 123. When the sliding rod 32 slides to the upward groove 123, the height of the second connecting plate 31 will be raised to the height of the first connecting plate 21. At this time, the second connecting plate 31 and the first connecting plate 21 will switch positions, thereby moving the new circuit breaker to the installation position. This saves the process of transporting the old circuit breaker to the warehouse and then transporting the new circuit breaker, thereby improving the installation efficiency of the new circuit breaker.

[0034] As an alternative embodiment, a structure is provided that can fix the new circuit breaker when it is raised.

[0035] The second connecting plate 31 is provided with a sliding member 35 at its top. The sliding member 35 includes a sliding block 351, a first actuating rod 352 at the bottom of the sliding block 351, a second actuating rod 353 at the bottom of the first actuating rod 352, and a connecting plate 354 at the top of the sliding block 351 for connecting the tooling. The cross-sectional area of ​​the first actuating rod 352 is larger than that of the second actuating rod 353, and the connection between the first actuating rod 352 and the second actuating rod 353 is provided with a rounded corner. The sliding block 351 has a block structure, with sliders on both sides and the first actuating rod 352 welded to the bottom.

[0036] The connecting plate 354 is provided with threaded holes, through which a clamp can be connected to assist in fixing the new circuit breaker.

[0037] The top of the second connecting plate 31 is provided with a groove 36 for sliding connection with the sliding block 351. The side of the sliding block 351 facing the sliding rod 32 is provided with an elastic element 37, and the other side of the elastic element 37 is connected to the second connecting plate 31. The side of the moving plate 33 is provided with a limiting groove 38, and the outer wall of the first actuating rod 352 is slidably connected to the outer wall of the limiting groove 38. The two sides of the groove 36 are provided with grooves that can slide with the sliders on both sides of the sliding block 351. The sliding block 351 can slide in the groove 36. The elastic element 37 will push the sliding block 351 to move away from the moving plate 33, thereby limiting the sliding of the sliding block 351. When the second moving plate 31 moves and gradually descends, it causes the first actuating rod 352 and the second actuating rod 353 to descend by a certain height. At this time, the second actuating rod 353 gradually moves away from the limiting groove 38, and the first actuating rod 352 contacts the edge of the limiting groove 38. Because the cross-sectional area of ​​the first actuating rod 352 is larger than that of the second actuating rod 353, displacement occurs when the first actuating rod 352 contacts the limiting groove 38. This causes the sliding block 351 to move towards the moving plate 33. The sliding block 351 then compresses the elastic element 37, thus causing the connecting plate 354 and the clamp mounted on it to move towards the center of the first moving plate 31. The clamp can hold the new circuit breaker, thus preventing it from bumping or swaying during the movement of the transfer trolley, improving the safety of transporting the new circuit breaker. At the same time, when the second moving plate 31 rises, it will gradually drive the second actuating rod 353 to rise. Since the cross-sectional area of ​​the second actuating rod 353 is smaller than that of the first actuating rod 352, there is a gap between the second actuating rod 353 and the limiting groove 38. At this time, the elastic element 37 will push the sliding block 351 to move away from the moving plate 33. The clamp will move away from the new circuit breaker. In this way, when changing the position of the old and new circuit breakers, the clamp will gradually engage with the new circuit breaker, making it easier for technicians to move the new circuit breaker.

[0038] As an alternative embodiment, the structure of the transmission component 4 is described.

[0039] It also includes a transmission component 4 for connecting the first moving component 2 and the second moving component 3. The transmission component 4 includes two drive wheels and a timing belt. The timing belt is sleeved on the outer wall of the drive wheels to form an elliptical transmission structure. Both drive wheels are rotatably connected to the support frame 13 through a rotating shaft. The two sides of the timing belt are respectively connected to the first moving component 2 and the second moving component 3. Therefore, when the timing belt rotates, it will drive the first moving component 2 and the second moving component 3 to move in opposite directions. At the same time, other suitable transmission components 4 can be used to replace the drive wheels and timing belt to achieve better results.

[0040] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
