Description

Rotary arm type elevator for railway wheel set Technical Field The invention relates to the technical field of railway vehicle equipment, in particular to a tumbler type lifter for a railway wheel set. Background At present, most railway vehicle sections and factories adopt overhead travelling cranes or ground forklifts to realize the function requirement of conveying railway wheel sets from a low-level track to a high-level track, and the main defects are that the production efficiency is low after the operation mode is relatively low, and few units adopt a lifting machine and a translation machine to realize the function, but the structure is complex, and the manufacturing cost, the operation and maintenance cost are high. Disclosure of Invention In view of the problems of the prior art, it is an object of the present invention to provide a tumbler type elevator for a railway wheel set, which solves the problems mentioned in the background art. In order to achieve the aim, the invention provides the technical scheme that a factory building 1 of a railway vehicle section or a vehicle factory comprises a low-level track 1A, a high-level track 1B, a wheel pair 2 and a tumbler type lifter 3, wherein the low-level track 1A and the high-level track 1B are positioned on the same straight line in a top view, the wheel pair 2 comprises an axle 2A and an excircle 2B of the wheels, which are positioned between two wheels, and the tumbler type lifter 3 positioned between the low-level track 1A and the high-level track 1B comprises a frame 3A, a rotating device 4 and a tumbler 5; The rotating device 4 is arranged on the frame 3A, the rotating device 4 can rotate the rotating arm 5 from the lowest position to the highest position or from the highest position to the low-height position, the rotating arm 5 comprises a groove 5A, the rotating arm 5 does not influence the wheel set 2 on the low-position track 1A to enter and exit the rotating arm type lifter 3 when in the lowest position, the axle 2A is placed in the groove 5A of the rotating arm 5 during the rotating process of the rotating arm 5, and the wheel set 2 is lifted from the low-position track 1A to the high-position track 1B or lowered from the high-position track 1B to the low-position track 1A through the rotating arm type lifter 3.

As a further scheme of the invention, the groove 5A comprises an arc section 5A1, the central line of the arc section 5A1 coincides with the central line of the rotating device 4, and when the wheel set 2 is positioned at the highest position, the outer circle of the axle 2A is contacted with the arc section 5A 1. As a further proposal of the invention, the tumbler type lifter 3 comprises a lifter 31 for lifting the wheel set 2 from the lower rail 1A to the upper rail 1B, wherein the upper rail 1B in the lifter 31 is inclined from the outside to the inside, when the groove 5A rotates to the highest position, the outer circle 2B of the wheel slides downwards out of the lifter 31 through the inclined upper rail 1B by the self weight of the wheel set 2. As a further proposal of the invention, the tumbler type elevator 3 comprises a descending machine 32 for descending the wheel set 2 from the high-level track 1B to the low-level track 1A, wherein the high-level track 1B in the descending machine 32 is inclined from the outside to the inside, when the groove 5A stays at the highest position, the wheel set 2 runs down along the high-level track 1B by self weight to the lowest point of the high-level track 1B and is blocked by the groove 5A, and the groove 5A conveys the wheel set 2 onto the low-level track 1A through a rotating device 4. In summary, compared with the prior art, the invention realizes the lifting and translation of the wheel set only by the rotation of the rotating arm, and has the main advantages of simple structure and high operation efficiency.
