At this time, the vehicle body 15 is in the test position. When the vehicle body 15 needs to be moved to the working position, the middle door 11 needs to be closed first. During the closing process of the middle door 11, the through hole of the side wall of the middle door 11 will correspond to the outer wall of the installation ring 2, and the side wall of the middle door 11 will squeeze the sliding block 412, and then the sliding block 412 will The first spring 413 is compressed along the inner wall of the through groove 5, and then the sliding block 412 drives the T-shaped plate 402 to move through the second connecting column 411.

Since the outer wall of the L-shaped block 902 corresponds to the inner wall of the lock groove 12, when the middle door 11 is closed, the L-shaped block 902 is engaged with the inside of the lock groove 12, and then when the vehicle body 15 is moved to the working position manually or electrically, the vehicle body 15 is locked. 5 drives the stopper 18 to move, and then the stopper 18 will be separated from the inside of the first slide groove 8, and then the L-shaped block 902 is no longer restricted by the stopper 18, and thus slides inside the first slide groove 8 under the elastic force of the second spring 903. The positioning rod 901 can be provided to limit the sliding of the L-shaped block 902 to prevent the L-shaped block 902 from deviating due to sliding, and then the protruding end of the L-shaped block 902 is engaged in the inside of the lock groove 12, and the interlocking function of the cross beam 1 and the middle door 11 is completed through the engagement of the lock groove 12; After that, the vehicle body 15 is moved from the working position to the test position manually or electrically.

At the same time, the sliding block 412 will be reset by the elastic force of the first spring 413, and then the interior of the lock block 406 will be engaged with the side wall of the block 3, thereby completing the restriction on the rotation of the screw rod 13, and at the same time, the limit column 409 will slide along the inner wall of the through hole 14 to the inside of the mounting ring 2, completing the restriction on the mounting handle.

[0025] By doing as above, when the vehicle body 15 needs to be moved to the working position, the vehicle body 15 can drive the stop block 18 away from the interior of the first slide groove 8, and the force generated by the first interlocking mechanism 4 squeezing the second spring 903 makes the L-shaped block 902 engage in the interior of the lock groove 12, thereby ensuring that the middle door 11 cannot be accidentally opened when the vehicle body 15 is not in the test position, avoiding the situation where the door 11 is accidentally opened during work, and effectively preventing safety accidents. The design of this interlocking device meets the requirements of safe operation, and can prevent safety accidents caused by misoperation or equipment failure to a certain extent. At the same time, it also improves the reliability and stability of the equipment and ensures the normal operation of the equipment.

[0026] Working principle: First, install the circuit breaker or the replacement circuit breaker on the car body 15, then align the roller 17 with the guide rail in the handcart room, and then push the chassis car loaded with the circuit breaker into the handcart room. At this time, the car body 15 is in the test position. When the car body 15 needs to be moved to the working position, the middle door 11 needs to be closed first. During the closing process of the middle door 11, the through hole of the side wall of the middle door 11 will correspond to the outer wall of the installation ring 2, and the side wall of the middle door 11 will squeeze the sliding block 412, and then the sliding block 412 will move along the The inner wall of the through groove 5 shrinks toward the inside of the inner groove 7, and the sliding block 412 compresses the first spring 413. Then the sliding block 412 drives the T-shaped plate 402 to move through the second connecting column 411. Since the bottom of the positioning column 401 is fixed inside the inner groove 7, the T-shaped plate 402 rotates around the positioning column 401 as the axis when moving. At the same time, the T-shaped plate 402 drives the first sliding column 404 to slide on the inner wall of the first slot 403. Then the first sliding column 404 drives the connecting block 405 to move. The inner wall of the inner groove 7 is slid away from the T-shaped plate 402, and then the inner wall of the locking block 406 is away from the outer wall of the block 3, so as not to affect the rotation of the block 3. At this time, the reducer 16 can be driven, and the chain installed on the output shaft of the reducer 16 is connected to the outer wall of the screw rod 13, and the vehicle body 15 can be directly driven by electricity to move. When the T-shaped plate 402 rotates, the second sliding column 408 is driven to slide on the inner wall of the second slot 407, and then the second sliding column 408 drives the limiting column 409 to approach The T-plate 402 slides along the inner wall of the through hole 14, and then the end of the limiting column 409 close to the block 3 will move away from the inside of the mounting ring 2, thereby releasing the restriction on the mounting handle inside the mounting ring 2. The handle can then be installed inside the mounting ring 2 and engage with the outer wall of the block 3. The handle can then be shaken to drive the screw rod 13 to rotate through the block 3. Since the vehicle body 15 and the screw rod 13 are threadedly connected, when the screw rod 13 rotates, the vehicle body 15 can switch between the test position and the working position.

[0027] As described above, when the vehicle body 15 needs to be moved to the working position, the middle door 11 must be closed first, so that the T-shaped plate 402 is driven to rotate by squeezing the sliding block 412, and then the connecting block 405 is driven to move by the first sliding column 404, so that the locking block 406 can be moved away from the side wall of the block 3, thereby achieving the interlocking between the middle door 11 and the screw rod 13, and realizing the effect that the vehicle body 15 cannot move without closing the middle door 11, effectively improving the safety of the operation process, ensuring that the middle door 11 remains closed during the operation of the equipment, and avoiding safety accidents; Since the stop block 18 fits with the L-shaped block 902, when the T-shaped plate 402 rotates, the connecting rod 904 is driven to slide on the inner wall of the second slide groove 10 through the first connecting column 410, and then the second spring 903 is compressed. Since the outer wall of the L-shaped block 902 corresponds to the inner wall of the lock groove 12, when the middle door 11 is closed, the L-shaped block 902 is engaged in the inner wall of the lock groove 12, and then when the vehicle body 15 is moved to the working position manually or electrically, the vehicle body 15 drives The stopper 18 moves, and then the stopper 18 will be separated from the first slide groove 8, and then the L-shaped block 902 is no longer restricted by the stopper 18, and thus slides in the first slide groove 8 under the elastic force of the second spring 903. The positioning rod 901 can be provided to limit the sliding of the L-shaped block 902 to prevent the L-shaped block 902 from deflecting due to sliding, and then the protruding end of the L-shaped block 902 is engaged in the lock groove 12, and the interlocking function of the cross beam 1 and the middle door 11 is completed by the engagement of the lock groove 12; After that, the vehicle body 15 is moved from the working position to the test position manually or electrically. During the process, the inclined surface of the stop block 18 is used to squeeze the inclined angle of the L-shaped block 902, so that the L-shaped block 902 can be squeezed and reset, and then the L-shaped block 902 will be disengaged from the interior of the lock groove 12, and then the middle door 11 can be opened. At the same time, the sliding block 412 will be reset by the elastic force of the first spring 413, and then the interior of the lock block 406 will be engaged with the side wall of the block 3, thereby completing the restriction on the rotation of the screw rod 13, and at the same time, the limit column 409 will slide along the inner wall of the through hole 14 to the inside of the mounting ring 2, completing the restriction on the mounting handle.

[0028] By doing as above, when the vehicle body 15 needs to be moved to the working position, the vehicle body 15 can drive the stop block 18 away from the interior of the first slide groove 8, and the force generated by the first interlocking mechanism 4 squeezing the second spring 903 makes the L-shaped block 902 engage in the interior of the lock groove 12, thereby ensuring that the middle door 11 cannot be accidentally opened when the vehicle body 15 is not in the test position, avoiding the situation where the door 11 is accidentally opened during work, and effectively preventing safety accidents. The design of this interlocking device meets the requirements of safe operation and can prevent safety accidents caused by misoperation or equipment failure to a certain extent.
