Abstract
Description
Technical Field
[0001] This invention relates to the field of railway vehicle equipment technology, specifically a swing arm lift for railway wheelsets. Background Technology
[0002] Currently, most railway vehicle depots and manufacturing plants use overhead cranes or ground forklifts to transport railway wheelsets from low-level tracks to high-level tracks. The main drawback is that the operation method is relatively outdated and the production efficiency is low. A very small number of units use lifts and translation machines to achieve this function, but their structure is very complex and the cost of construction and operation and maintenance is also very high. 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 slewing boom lift 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 a railway vehicle depot or vehicle factory includes a low-level track 1A, a high-level track 1B, a wheelset 2, and a swing arm lift 3. The low-level track 1A and the high-level track 1B are located on the same straight line in a top view. The wheelset 2 includes an axle 2A located between two wheels and an outer circle 2B of the wheel. The swing arm lift 3 located between the low-level track 1A and the high-level track 1B includes a frame 3A, a rotating device 4, and a swing arm 5. The rotating device 4 is installed on the frame 3A. The rotating device 4 enables the rotating arm 5 to rotate from the lowest position to the highest position or from the highest position to the low-high position. The rotating arm 5 includes a groove 5A. When the rotating arm 5 is in the lowest position, it does not affect the entry and exit of the wheelset 2 on the low-position rail 1A into the rotating arm lift 3. During the rotation of the rotating arm 5, the axle 2A rests in the groove 5A of the rotating arm 5. The rotating arm lift 3 enables the wheelset 2 to be lifted from the low-position rail 1A to the high-position rail 1B, or lowered from the high-position rail 1B to the low-position rail 1A.
[0005] As a further aspect of the present invention: the end of the high-position track 1B includes a fixed roller 6, the center line of the two fixed rollers 6 coincides with the center line of the rotating device 4, and the outer circle of the fixed roller 6 is tangent to the high-position track 1B, that is, during the lifting or lowering process of the wheelset 2, the outer circle 2B of the wheel rotates along the outer circle of the fixed roller 6.
[0006] As a further aspect of the present invention: the groove 5A includes an arc segment 5A1, the center line of the arc segment 5A1 coincides with the center line of the rotating device 4; when the wheelset 2 is in the highest position, the outer circle of the axle 2A contacts the arc segment 5A1.
[0007] As a further aspect of the present invention: the swing arm lift 3 includes a lift 31 that lifts the wheelset 2 from the low-position rail 1A to the high-position rail 1B. The high-position rail 1B in the lift 31 is inclined with the outer side higher than the inner side. When the groove 5A rotates to the highest position, the outer circle 2B of the wheel slides down the inclined high-position rail 1B and out of the lift 31 by the weight of the wheelset 2.
[0008] As a further aspect of the present invention: the swing arm lift 3 includes a lowering mechanism 32 that lowers the wheelset 2 from the high-level track 1B to the low-level track 1A. The high-level track 1B in the lowering mechanism 32 is inclined with the outer side lower and the inner side higher. When the groove 5A is at its highest position, the wheelset 2 moves down along the high-level track 1B by its own weight to the lowest point of the high-level track 1B and is blocked by the groove 5A. The groove 5A transports the wheelset 2 to the low-level track 1A through the rotating device 4.
[0009] In summary, compared with the prior art, the present invention achieves the lifting and translation of the wheelset only by rotating the arm. Its main advantages are: simple structure and high operating efficiency. Attached Figure Description

[0012] The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0013] Please see Figures 1-5 In this embodiment of the invention, the workshop 1 of the railway vehicle depot or vehicle factory includes a low-level track 1A, a high-level track 1B, a wheelset 2, and a swing arm lift 3. The low-level track 1A and the high-level track 1B are located on the same straight line in the top view. The wheelset 2 includes an axle 2A located between two wheels and an outer circle 2B of the wheel. The swing arm lift 3 located between the low-level track 1A and the high-level track 1B includes a frame 3A, a rotating device 4, and a swing arm 5. The rotating device 4 is installed on the frame 3A. The rotating device 4 enables the rotating arm 5 to rotate from the lowest position to the highest position or from the highest position to the low-high position. The rotating arm 5 includes a groove 5A. When the rotating arm 5 is in the lowest position, it does not affect the entry and exit of the wheelset 2 on the low-position rail 1A into the rotating arm lift 3. During the rotation of the rotating arm 5, the axle 2A rests in the groove 5A of the rotating arm 5. The rotating arm lift 3 enables the wheelset 2 to be lifted from the low-position rail 1A to the high-position rail 1B, or lowered from the high-position rail 1B to the low-position rail 1A.
[0014] The end of the high-position track 1B includes fixed rollers 6. The center lines of the two fixed rollers 6 coincide with the center line of the rotating device 4, and the outer circle of the fixed rollers 6 is tangent to the high-position track 1B. That is, during the lifting or lowering process of the wheelset 2, the outer circle 2B of the wheel rotates along the outer circle of the fixed rollers 6.
[0015] The groove 5A includes an arc segment 5A1, the center line of which coincides with the center line of the rotating device 4; when the wheelset 2 is in the highest position, the outer circle of the axle 2A contacts the arc segment 5A1.
[0016] The swing arm lift 3 includes a lift 31 that lifts the wheel set 2 from the low rail 1A to the high rail 1B. The high rail 1B in the lift 31 is inclined with the outer side higher than the inner side. When the groove 5A rotates to the highest position, the outer circle 2B of the wheel slides down the inclined high rail 1B and out of the lift 31 by relying on the weight of the wheel set 2.
[0017] The swing arm lift 3 includes a lowering mechanism 32 that lowers the wheelset 2 from the high-level track 1B to the low-level track 1A. The high-level track 1B in the lowering mechanism 32 is inclined with the outer side lower and the inner side higher. When the groove 5A is at its highest position, the wheelset 2 moves down the high-level track 1B by its own weight to the lowest point of the high-level track 1B and is blocked by the groove 5A. The groove 5A transports the wheelset 2 to the low-level track 1A through the rotating device 4.
