Abstract
Description
Technical Field
[0001] The invention relates to the technical field of railway passenger car equipment, in particular to a high-low staggered single-layer wheel pair warehouse for railway passenger cars. Background Art
[0002] Currently, there are two structural forms of wheelset depots (also known as "wheel storage depots") for railway passenger cars: 1) In a top-down view, the wheelsets are staggered and non-overlapping, allowing a crane or truss robot to directly grab any wheelset in the depot. However, this has the main disadvantage of requiring a large area. 2) In a top-down view, there is overlap between the lower and higher wheelsets. Although this requires a small area, the higher wheelset must be removed before grabbing the lower wheelset. This has the main disadvantage of low operating efficiency.
[0003] In the top view of the present invention, the low-position wheelset and the high-position wheelset partially overlap, but when grabbing the low-position wheelset, there is no need to move the high-position wheelset. Summary of the Invention
[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a single-layer wheelset warehouse with height staggered for railway passenger cars to solve the problems mentioned in the above background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a building 1 of a railway passenger car depot or a railway passenger car factory includes a single-layer wheelset warehouse 1A and passenger car wheels 2. The single-layer wheelset warehouse 1A includes a low-level support 3, a high-level support 4, and a truss robot 5. The passenger car wheels 2 include a wheel rim 2A, an axle 2B, a low-level wheelset 23 on the low-level support 3, and a high-level wheelset 24 on the high-level support 4. The low-level wheelset 23 and the high-level wheelset 24 are staggered. In a top view, the wheel rims of the low-level wheelset 23 and the high-level wheelset 24 partially overlap. Assuming the diameter of the wheel rim 2A is D and the diameter of the axle 2B is d, the minimum clearance required by the truss robot 5 to remove the wheel rim 2A of the low-position wheelset 23 from the axles 2B of two adjacent high-position wheelsets 24 is 2t. Therefore, the center distance between two adjacent equal-height passenger car wheel sets 2 is greater than or equal to D+2t+d; the truss robot 5 can grasp the low-position wheelset 23 for outbound operation without moving the high-position wheelset 24.
[0006] As a further solution of the present invention: the truss robot 5 includes a trolley 5A, a trolley 5B, a gripper device 5C and a lifting device 5D. The length direction of the factory building 1 is longitudinal. The trolley 5A that moves longitudinally includes a trolley body 5A1 and a transverse track 5A2. The transverse track 5A2 is installed on the trolley body 5A1. The trolley 5B includes a trolley body 5B1 and a running device 5B2. The trolley body 5B1 runs on the transverse track 5A2 through the running device 5B2. The lifting device 5D is installed on the trolley body 5B1. The gripper device 5C includes a gripper seat 5C1 and a gripper 5C2. The gripper 5C2 for gripping the passenger car wheel set 2 is installed on the gripper seat 5C1. The gripper seat 5C1 is installed on the lifting device 5D.
[0007] As a further embodiment of the present invention, the lifting device 5D includes a flexible traction device 5D1 and a rigid guide device 6. The rigid guide device 6 includes a column device 6A and a slider 6B. The column device 6A includes a fixed column 6A1 and an intermediate column device 6A2. The clamping claw seat 5C1 is mounted on the slider 6B. The slider 6B can move vertically on the intermediate column device 6A2. The intermediate column device 6A2 can move vertically on the fixed column 6A1. The fixed column 6A1 is mounted on the trolley body 5B1. The trolley body 5B1 can run on the transverse track 5A2 via the running device 5B2. One end of the flexible traction device 5D1 is fixed on the clamping claw seat 5C1, and the other end is fixed on the fixed column 6A1 or the trolley body 5B1; the flexible traction device 5D1 can realize the vertical lifting of the clamping claw seat 5C1, and the rigid guide device 6 can prevent the clamping claw seat 5C1 from shaking during lifting.
[0008] As a further solution of the present invention: the intermediate column device 6A2 includes a starting column 6A2A, an intermediate column 6A2B and an end column 6A2C, the slider 6B can move vertically on the end column 6A2C, the end column 6A2C can move vertically on the intermediate column 6A2B, the intermediate column 6A2B can move vertically on the starting column 6A2A, and the starting column 6A2A can move vertically on the fixed column 6A1.
[0009] As a further solution of the present invention, the low-position support 3 includes a low-position V-shaped positioning block 3A, and the low-position wheelset 23 is placed on the low-position V-shaped positioning block 3A. Assuming that the length direction of the factory building 1 is the longitudinal direction and the length direction of the passenger car wheel set 2 is the transverse direction, the main operating steps for the truss robot 5 to grasp the low-position wheelset 23 located below the high-position wheelset 24 are as follows: 1) The truss robot 5 moves to a position where the center line of the gripper device 5C coincides with the center line of the low-position wheelset 23; 2) The lifting device 5D descends to the set position; 3) The gripper device 5C grabs the low-position wheelset 23; 4) The lifting device 5D rises, so that the bottom of the wheel rim 2A of the low-position wheelset 23 is higher than the low-position V-shaped positioning block 3A; 5) The clamping jaw device 5C moves laterally to the set distance; 6) The gripper device 5C carries the low-position wheelset 23 and passes between the axles 2B of two adjacent high-position wheelsets 24 . The truss robot 5 completes the operation of grasping and removing the low-position wheelset 23 .
[0010] To sum up, compared with the prior art, in the top view, the present invention has partial overlap between the low-position wheelset and the high-position wheelset, but when grabbing the low-position wheelset, there is no need to move the high-position wheelset. Its main advantages are: the railway passenger car wheel warehouse occupies a small area and the wheelset in and out of the warehouse are highly efficient. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0014] See also Figures 1-14 In an embodiment of the present invention, a building 1 of a railway passenger car section or a railway passenger car factory includes a single-layer wheelset warehouse 1A and passenger car wheels 2. The single-layer wheelset warehouse 1A includes a low-position support 3, a high-position support 4, and a truss robot 5. The passenger car wheels 2 include a wheel rim 2A, an axle 2B, a low-position wheelset 23 on the low-position support 3, and a high-position wheelset 24 on the high-position support 4. The low-position wheelset 23 and the high-position wheelset 24 are staggered. In a top view, the wheel rim of the low-position wheelset 23 partially overlaps with the wheel rim of the high-position wheelset 24. Assuming the diameter of the wheel rim 2A is D and the diameter of the axle 2B is d, the minimum clearance required by the truss robot 5 to remove the wheel rim 2A of the low-position wheelset 23 from the axles 2B of two adjacent high-position wheelsets 24 is 2t. Therefore, the center distance between two adjacent equal-height passenger car wheel sets 2 is greater than or equal to D+2t+d; the truss robot 5 can grasp the low-position wheelset 23 for outbound operation without moving the high-position wheelset 24.
[0015] The truss robot 5 includes a trolley 5A, a trolley 5B, a gripper device 5C and a lifting device 5D. The length direction of the factory building 1 is longitudinal.

[0019] It should be noted that the intermediate column device 6A2 can also be a single column, that is, there is neither an intermediate column 6A2B nor an end column 6A2C, and the slider 6B moves vertically directly on the initial column 6A2A.
[0020] The low-position support 3 includes a low-position V-shaped positioning block 3A, and the low-position wheelset 23 is placed on the low-position V-shaped positioning block 3A. Assuming that the length direction of the factory building 1 is the longitudinal direction and the length direction of the passenger car wheel set 2 is the transverse direction, the main operation steps for the truss robot 5 to grasp the low-position wheelset 23 located below the high-position wheelset 24 are as follows: 1) The truss robot 5 moves to a position where the center line of the gripper device 5C coincides with the center line of the low-position wheelset 23; 2) The lifting device 5D descends to the set position; 3) The gripper device 5C grabs the low-position wheelset 23; 4) The lifting device 5D rises, so that the bottom of the wheel rim 2A of the low-position wheelset 23 is higher than the low-position V-shaped positioning block 3A; 5) The clamping jaw device 5C moves laterally to the set distance; 6) The gripper device 5C carries the low-position wheelset 23 and passes between the axles 2B of two adjacent high-position wheelsets 24 . The truss robot 5 completes the operation of grasping and removing the low-position wheelset 23 .
[0021] It should be noted that the length direction of the passenger car wheel set 2 may also be longitudinal.
