Technical Field
[0001] This invention relates to the field of railway vehicle maintenance and production technology, specifically a reciprocating push-pull conveyor that can directly hook wheelsets into the conveyor. Background Technology
[0002] Currently, the transport of railway wheelsets from transversely arranged plate chain conveyors to longitudinally arranged reciprocating push-pull conveyors is mainly accomplished manually or by wheel pullers. Its main disadvantages are: high labor intensity for workers, low work efficiency, and large construction investment. Summary of the Invention
[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a reciprocating push-pull conveyor that can directly hook wheelsets in, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: The workshop 1 of a railway vehicle depot or vehicle factory includes a track 1A, wheelsets 2, a plate chain conveyor 8, and a reciprocating push-pull conveyor 3. The length direction of the track 1A is longitudinal. The wheelsets 2 running on the track 1A include axles 2A and wheel flanges 2B. The reciprocating push-pull conveyor 3 includes a fixed base frame 3A, a push-pull device 3B, and a reciprocating push-pull drive. The fixed base frame 3A located between the two rails that make up the track 1A includes a push-pull guide rail 3A1. The reciprocating push-pull device 3B, whose top surface is lower than the lowest position of the axle 2A, includes a push-pull frame 3B1, a traveling device 3B2, and several sets of telescopic push head devices 4.
[0005] Both the traveling device 3B2 and the telescopic push head device 4 are mounted on the push-pull frame 3B1. The push-pull frame 3B1 runs on the push-pull guide rail 3A1 via the traveling device 3B2. The telescopic push head device 4 includes a telescopic device 4A and a push head device 4B. The push head device 4B includes a push head 4B1. When the push head device 4B extends the push head 4B1 laterally into the rear of the wheel flange 2B of the wheel pair 2 being pushed through the telescopic device 4A, or extends the push head 4B1 upward to block the rear of the axle 2A of the wheel pair 2 being pushed, the wheel pair 2 moves forward by reciprocating push-pull drive to push the rear of the wheel flange 2B or the axle 2A of the front wheel pair 2.
[0006] The plate chain conveyor 8, which is perpendicular to the reciprocating push-pull conveyor 3, includes an arc-shaped panel 8A. When the wheel pair 2 on the arc-shaped panel 8A is aligned with the track 1A, the last push head 4B1 at the tail of the reciprocating push-pull conveyor 3 can extend from above the arc-shaped panel 8A and below the axle 2A. After reaching the set position, the wheel pair 2 is disengaged from the plate chain conveyor 8 and hooked into the reciprocating push-pull conveyor 3 by the reciprocating push-pull drive.
[0007] As a further aspect of the present invention: the reciprocating push-pull conveyor 3 includes a stopper 3D, which is installed on a fixed base frame 3A or the ground. When the pusher head 4B1 reaches the set stroke and stops moving forward, the wheelset 2 is locked between the pusher head 4B1 and the stopper 3D.
[0008] As a further aspect of the present invention: the telescopic device 4A includes a lateral telescopic device 5, which includes a longitudinal push rod 5A and a lateral push drive 5B. The push device 4B includes a lateral push device 6, which includes a roller head 6A and a push shaft 6B. The roller head 6A is mounted on the head of the push shaft 6B, and several push shafts 6B are fixed on the longitudinal push rod 5A. The longitudinal push rod 5A extends or retracts the roller head 6A through the lateral push drive 5B, thereby achieving lateral telescopic movement.
[0009] As a further aspect of the present invention: the stopper 3D includes a lateral stopper 7 mounted on a fixed base frame 3A. The lateral stopper 7 includes a longitudinal stopper rod 7A, a stop crossbar 7B, and a crossbar drive 7C. Several stop crossbars 7B are mounted on the longitudinal stopper rod 7A. The longitudinal stopper rod 7A extends or retracts the stop crossbars 7B through the crossbar drive 7C, thereby realizing reciprocating lateral extension and retraction motion.
[0010] As a further aspect of the present invention: the reciprocating push-pull conveyor 3 includes a backstop 3E, which is installed on a fixed base frame 3A or on the ground.
[0011] As a further aspect of the present invention: the longitudinal rod 5A of the pusher head includes a stop device 5A1, which is mounted on the longitudinal rod 5A of the pusher head; when the roller head 6A stops pushing the wheelset 2, the stop device 5A1 can limit the distance that the wheelset 2 can continue to roll forward.
[0012] In summary, compared with existing technologies, the main features of this invention are: utilizing the telescopic device and pusher device inherent in the reciprocating push-pull conveyor, the wheelset is hooked into the reciprocating push-pull conveyor via the last set of pushers at the tail. The main advantages of this invention are: low labor intensity, high operating efficiency, and low construction investment. Attached Figure Description
