Description

Technical Field

[0001] The invention relates to the technical field of maintenance and production of railway vehicles, in particular to a wheel pushing device used for railway wheel pair transportation. Background Art

[0002] At present, the automated transportation of railway wheelsets is mainly completed by AGV carts or ordinary wheelset conveyors. The main defect of AGV carts is that they can only transport wheelsets one by one; and the main defect of ordinary wheelset conveyors is that they can only operate as a whole. When the wheelsets at the input end of the ordinary wheelset conveyor enter randomly, once there is a missing part in the middle of the conveyor, it is difficult to add the wheelset. 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 wheel pushing device for railway wheel set transportation to solve the problems mentioned in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a railway vehicle depot or a vehicle factory building 1 includes a track 1A, a wheel pair 2 and a wheel pusher 3, the length direction of the track 1A is assumed to be longitudinal, the wheel pair 2 running on the track 1A includes an axle 2A and a wheel flange 2B, the wheel pusher 3 includes a fixed chassis 3A, a push-pull device 3B and a push-pull drive, the fixed chassis 3A located between the two rails constituting the track 1A includes a push-pull guide rail 3A1, the top surface of the push-pull guide rail 3A1 being lower than the lowest position of the axle 2A The pulling device 3B includes a push-pull frame 3B1, a running device 3B2 and a plurality of groups of transverse telescopic devices 4. The running device 3B2 and the transverse telescopic devices 4 are both installed on the push-pull frame 3B1. The push-pull frame 3B1 runs on the push-pull guide rail 3A1 through the running device 3B2. The transverse telescopic device 4 includes a push rod device 5 and a stop rod device 6. The push rod device 5 includes a telescopic push rod 5A, a push rod drive 5Y and a push head 5B. The stop rod device 6 includes a telescopic stop rod 6A, a stop rod drive 6Y and a stop head 6B. When the telescopic push rod 5A is extended horizontally by the push rod driving 5Y, the push head 5B installed at the head of the telescopic push rod 5A can be inserted into the gap between the two adjacent wheel pairs 2, and then the rear part of the wheel rim 2B of the front wheel pair 2 is pushed by the push-pull driving, so that the wheel pair 2 moves forward; after the wheelset 2 moves forward, the telescopic blocking rod 6A is extended horizontally by the blocking rod driving 6Y, and the blocking head 6B located at the head of the telescopic blocking rod 6A can block the front of the wheel rim 2B of the front wheelset 2; When the push-pull drive stops moving, the front wheel pair 2 is stuck between the push head 5B and the stopper head 6B and stops at the set position of the track 1A. The push-pull drive can realize the reciprocating motion of the push-pull frame 3B1.

[0005] As a further solution of the present invention: the pushing head 5B and the blocking head 6B are located at the same height, and the wheel rim diameter of the wheelset 2 is d. When the track 1A is fully covered with wheelsets 2, the center distance between the wheel rims of two adjacent wheelsets 2 is d+a. Then, the center distance between two adjacent sets of transverse telescopic devices 4 installed on the push-pull frame 3B1 is also equal to d+a.

[0006] As a further solution of the present invention: when the push-pull device 3B is located at the original position, the center of the push head 5B is located between the center of two adjacent wheel pairs and the wheel rim 2B of the previous wheel pair 2.

[0007] As a further solution of the present invention: the wheel pushing device 3 utilizes the extension and contraction of the push head 5B and the stop head 6B to not only push all the wheel pairs 2 to run simultaneously, but also push only any one wheel pair 2 forward to fill a vacant position in front of this wheel pair 2.

[0008] As a further solution of the present invention: the track 1A includes a plurality of push-pull frames 3B1 that reciprocate and have different travel distances and are arranged in series to push the wheel devices 3 to meet the requirement that the wheel pairs 2 have different spacings on the track 1A.

[0009] As a further solution of the present invention: the wheel pushing device 3 includes a stopper 3D, and the stopper 3D is installed on the fixed base frame 3A or the ground.

[0010] As a further solution of the present invention: the wheel pushing device 3 includes a backstop 3E, and the backstop 3E is installed on the fixed base frame 3A or the ground.

[0011] As a further solution of the present invention: the sliding frame 3B1 includes a step cover 3B1A.

[0012] In summary, compared with the prior art, the main features of the present invention are: the wheel pushing device can push all wheelsets to run simultaneously by using the extension and contraction of the push head and the stop head, and can also push only one wheelset forward to fill a vacant position in front of the wheelset; especially on the inspection line of the axle workshop, when the paint of the wheelset is not dry and the axle is not allowed to be pushed, the present invention has unparalleled advantages. The main advantages of the present invention are: low labor intensity and high operation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
