Description

Technical Field

[0001] This utility model relates to the field of railway vehicle maintenance and production technology, specifically a reciprocating push-pull conveyor for railway wheelsets. Background Technology

[0002] Currently, in railway depots or rolling stock factories, wheelsets are mainly transported by human power, resulting in very high labor intensity and low work efficiency for workers. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a reciprocating push-pull conveyor for railway wheelsets 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 the wheelset workshop of a railway vehicle depot or vehicle factory includes a track 1A, wheelsets 2 and a reciprocating push-pull conveyor 3. The length direction of the track 1A is longitudinal. The wheelset 2 running on the track 1A includes an axle 2A and a wheel flange 2B. The reciprocating push-pull conveyor 3 includes a fixed base frame 3A, a push-pull device 3B, a stopper 3D and a reciprocating push-pull drive. The stopper 3D is installed on the fixed base frame 3A or on the ground. The fixed base frame 3A located between the two rails that make up the track 1A includes a push-pull guide rail 3A1.

[0005] 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. The traveling device 3B2 and the telescopic push head devices 4 are both mounted on the push-pull frame 3B1. The push-pull frame 3B1 runs on the push-pull guide rail 3A1 through the traveling device 3B2.

[0006] The telescopic pusher device 4 includes a telescopic device 4A and a pusher device 4B. The pusher device 4B includes a pusher 4B1. When the pusher device 4B extends the pusher 4B1 laterally behind the rim 2B of the wheel pair 2 being pushed, or extends it vertically behind the axle 2A of the wheel pair 2 being pushed, it pushes the rim 2B or the rear of the axle 2A of the front wheel pair 2 through a reciprocating push-pull drive, causing the wheel pair 2 to move forward. When the push-pull frame 3B1 reaches the set stroke, the reciprocating push-pull drive stops running. At this time, the wheel pair 2 is stuck between the pusher 4B1 and the stopper 3D.

[0007] As a further embodiment of this utility model: 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 installed at 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 realizing the lateral telescopic movement.

[0008] As a further embodiment of this utility model: the stop device 3D includes a lateral stop device 7 mounted on a fixed base frame 3A. The lateral stop device 7 includes a longitudinal stop rod 7A, a stop crossbar 7B, and a crossbar drive 7C. Several stop crossbars 7B are mounted on the longitudinal stop rod 7A. The longitudinal stop rod 7A causes the stop crossbars 7B to extend or retract through the crossbar drive 7C, thereby achieving lateral telescopic movement.

[0009] As a further embodiment of this utility model: the reciprocating push-pull conveyor 3 includes a backstop 3E, which is installed on a fixed base frame 3A or on the ground.

[0010] As a further embodiment of this utility model: the longitudinal rod 5A of the pusher includes a stop device 5A1. When the roller head 6A stops pushing the wheelset 2, the stop device 5A1 can limit the rolling distance of the wheelset 2.

[0011] As a further embodiment of this utility model: the reciprocating push-pull conveyor 3 includes a conveyor for wheelset inspection lines.

[0012] In summary, compared with the existing technology, the main advantage of this utility model is that it can realize unmanned transportation of railway wheelsets through a reciprocating push-pull conveyor, which greatly improves the operation efficiency. Attached Figure Description
