[0024] The purpose of the present invention is to provide a circuit breaker maintenance vehicle, which solves the problem that maintenance personnel cannot directly perform maintenance operations on the maintenance vehicle, and the operation process is simple, time-saving and labor-saving.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

The sliding mechanism is arranged at the lower part of the frame, so that the frame is easy to move. The lifting drive mechanism is arranged on the frame and is used to drive the lifting bracket 7 to reciprocate in the vertical direction. The lifting bracket 7 is used to place the circuit breaker 200 and drive it to rise and fall. The two flipping mechanisms are symmetrically arranged at the upper part of the frame. The flipping mechanism includes a linear telescopic driving component, a flip bracket and a latch 11. One end of the flip bracket is rotatably mounted on the upper part of the frame through the latch 11. The latch 11 can slide in the horizontal direction relative to the frame and can be inserted into the mounting hole of the circuit breaker 200. A mounting hole is arranged on both sides of the circuit breaker 200. The latch 11 corresponds to the mounting hole one by one. The two ends of the linear telescopic driving component are respectively hinged to the frame and the other end of the flip bracket. The linear telescopic driving component is used to drive the flip bracket to drive the circuit breaker 200 to flip.

[0027] During operation, the circuit breaker 200 is taken out of the control cabinet and placed on the lifting bracket 7. The lifting bracket 7 drives the circuit breaker 200 to rise, so that the latch 11 is aligned with the mounting hole of the circuit breaker 200, and the latch 11 is pushed toward the circuit breaker 200 to be inserted into the mounting hole of the circuit breaker 200. The lifting bracket 7 descends to move it away from the circuit breaker 200. The linear telescopic drive component drives the flip bracket to drive the circuit breaker 200 to rotate 90° and then stop. At this time, the maintenance personnel can repair the circuit breaker 200 at the front end of the maintenance vehicle facing the bottom of the circuit breaker 200, which solves the problem that the maintenance personnel cannot directly operate and repair on the maintenance vehicle, making the operation process simple and saving time and effort.

[0028] Specifically, the flip bracket includes a rotating member and a limit support member, one end of the rotating member is rotatably mounted on the upper part of the frame through a latch 11, and the other end of the rotating member is hinged to the linear telescopic drive component, and a limit support member is provided on the side of each rotating member close to another rotating member, and the limit support member is used to provide limit support for the circuit breaker 200 during the flipping process. When the linear telescopic drive component is extended, it can drive the rotating member and the limit support member to rotate, thereby driving the circuit breaker 200 to flip.

[0029] The rotating member in this embodiment is a U-shaped plate 12, which includes an inner plate, an outer plate and a connecting plate. The inner plate and the outer plate are both connected to the connecting plate. The inner plate of a U-shaped plate 12 is arranged on a side close to another U-shaped plate 12, and the inner plate and the outer plate are arranged perpendicular to the connecting plate.

The power component is arranged at the upper part of the bottom bracket 1, and each transmission assembly is arranged on a hollow column 3. The two ends of the lifting bracket 7 are respectively connected to the two transmission assemblies.

[0032] A support beam 9 is disposed on the front side of the upper part of each hollow column 3. In this embodiment, the support beam 9 is disposed horizontally, and the two support beams 9 are parallel to each other. One end of each flip bracket is rotatably mounted on the front end of a support beam 9 through a latch 11. Specifically, the latch 11 is used to sequentially pass through the outer plate, the front end of the support beam 9, and the inner plate. One end of each linear telescopic drive component is hinged on a hollow column 3 and is located below a support beam 9. Specifically, the housing of each electric push rod 10 is hinged on a hollow column 3 and is located below a support beam 9.

The connecting assembly passes through the vertical strip hole 4 and extends to the outside and is connected to the lifting bracket 7. The power component is used to drive the two driving pulleys to rotate, so that the synchronous belt 5 moves, and then the lifting bracket 7 connected to the synchronous belt 5 through the connecting assembly reciprocates in the vertical direction.

[0034] In order to ensure that the lifting bracket 7 is firmly connected to the synchronous belt 5 so that the lifting bracket 7 moves stably, the connecting assembly includes a plurality of connecting blocks 6 arranged in sequence along the conveying direction of the synchronous belt 5 , and each connecting block 6 is connected to the lifting bracket 7 .

[0036] In this specific embodiment, the power component is a dual-output shaft motor 8, and the two power output shafts of the dual-output shaft motor 8 are respectively connected to the two driving pulleys so that the two driving pulleys rotate synchronously.

[0037] Specifically, the sliding mechanism includes a plurality of wheels 2 , and each wheel 2 is mounted on the lower portion of the bottom bracket 1 .

[0039] Step 2: Figure 2 As shown, the dual-output shaft motor 8 works so that the lifting bracket 7 drives the circuit breaker 200 to rise. Under the action of the travel switch, the lifting bracket 7 rises to a certain height and then stops, and the circuit breaker 200 is moved to fit with the first support plate and the second support plate. At this time, the mounting holes of the circuit breaker 200 are aligned with the pins 11, and the two pins 11 are respectively inserted into the two mounting holes of the circuit breaker 200.

[0040] Step 3: Control the dual-output shaft motor 8 to lower the lifting bracket 7 by about 200 mm and stop.

[0041] Step 4: Figure 3 and Figure 4 As shown, the electric push rod 10 is started to extend, so that the circuit breaker 200 rotates 90° around the latch 11 and then stops.

[0042] Step 5: The maintenance personnel repair the circuit breaker 200 at the front end of the maintenance vehicle facing the bottom of the circuit breaker 200 .

[0043] Step 6: Start the electric push rod 10 to retract, and the circuit breaker 200 flips 90 degrees in the opposite direction to the original position.
