Description

Technical Field

[0001] The present invention relates to the technical field of railway vehicle maintenance and production, and specifically to a conveying system composed of a truss robot and a longitudinal track. Background Art

[0002] Currently, in the axle workshops of each vehicle depot across the country, although there are 2-3 parallel, independent and basically identical maintenance operation lines arranged longitudinally in the workshop, and each operation line is composed of a longitudinal ground track and various maintenance equipment, there is no wheel set buffer area that can be shared by all maintenance equipment in their overall layout. For each maintenance equipment on each longitudinal track, they are arranged in series, and there is a relatively long longitudinal ground track between each maintenance equipment on the same operation line to buffer the wheel sets at a certain work station. However, the ground track on this kind of operation line cannot be shared by each maintenance equipment.

[0003] When a certain maintenance equipment fails, the corresponding wheel set buffer section far fails to meet the buffer demand for wheel sets in production scheduling. At the same time, the wheel set buffer sections on other operation lines may be idle. In addition, because the area occupied by the ground turntable is relatively large, there are very few transverse tracks installed in the axle workshops of each vehicle depot across the country, which makes it very difficult to transfer wheel sets between each longitudinal track. Once a certain equipment on a longitudinal track fails, all the equipment on this longitudinal track may stop production.

[0004] Although theoretically, the problem of parallel maintenance of wheel sets between each longitudinal track can be solved by increasing turntables and transverse tracks, it is difficult to implement in practice due to the limitation of the workshop area.

[0005] Another drawback of the prior art is that the transportation of wheel sets between each maintenance work station is mainly achieved by manually pushing the wheel sets to roll on the ground track, resulting in very low operation efficiency of maintaining wheel sets and utilization rate of maintenance equipment, and very high labor intensity of workers. Summary of the Invention

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a conveying system composed of a truss robot and a longitudinal track to solve the problems mentioned in the above background art.

[0007] To achieve the above object, the present invention provides the following technical solutions: In the workshop building 1 of the wheel and axle workshop in a railway vehicle depot or vehicle factory, there are wheel sets 1A, two or three longitudinal tracks 1X arranged side by side longitudinally, several maintenance equipment 2, a wheel set buffer area 3, and a truss robot 4. Each longitudinal track 1X is provided with various maintenance equipment 2 arranged in the order of the process flow. Between two adjacent maintenance equipment 2 on the same longitudinal track 1X, there is a transition track 5; the truss robot 4 is used to convey the wheel set 1A between the wheel set buffer area 3 and the transition track 5.

[0008] As a further solution of the present invention: The longitudinal track 1X includes a track conveying device 6, and the track conveying device 6 is used to realize the running and stopping of the wheel set 1A on the longitudinal track 1X.

[0009] As a further solution of the present invention: The track conveying device 6 includes a wheel pusher 6A, a stopper 6B, and a backstop 6C. The wheel pusher 6A is used to make the wheel set 1A run on the longitudinal track 1X, the stopper 6B is used to prevent the wheel set 1A from moving forward on the longitudinal track 1X, and the backstop 6C is used to prevent the wheel set 1A from moving backward on the longitudinal track 1X.

[0010] As a further solution of the present invention: The truss robot 4 includes a trolley 4A, a carriage 4B, a lifting device 4C, and a gripper 4D. The trolley 4A includes a transverse track 4AY; the gripper 4D for grasping the wheel set 1A is installed on the lifting device 4C, and the lifting device 4C is installed on the carriage 4B; the carriage 4B runs on the transverse track 4AY, and the trolley 4A runs longitudinally in the workshop building 1.

[0011] As a further solution of the present invention: The workshop building 1 includes a steel platform 7. The steel platform 7 includes an opening 7A and a safety cover 7B, and the safety cover 7B can cover the opening 7A located above the transition track 5.

[0012] As a further solution of the present invention: The wheel set buffer area 3 includes a steel platform buffer area 3A located above the steel platform 7.

[0013] In summary, compared with the prior art, the main features of the present invention are as follows: 1) A wheel set buffer area that can be shared by each maintenance equipment is provided, and the wheel set buffer area can be arranged near the steel platform, so the floor area is greatly reduced; 2) Since the truss robot does not need to rotate the wheel set by 90 degrees when grasping the wheel set, and even if the wheel set needs to be rotated by 90 degrees, it can be rotated in the air after leaving the ground, so its floor area is very small; 3) Since the transverse tracks are in parallel, when only one maintenance equipment is arranged on each of the 2-3 transverse tracks under the same process, through the front plate chain conveyor and the rear plate chain conveyor, the parallel arrangement of 2-3 maintenance equipments with the same configuration under the same process can be realized; when multiple maintenance equipments are arranged on the same transverse track, a transition track is arranged between adjacent maintenance equipments, and the truss robot takes and places the wheel set on the transition track to realize the parallel arrangement of all maintenance equipments, that is, a truly fully flexible production line is formed. Therefore, the main advantages of the present invention are: low labor intensity of workers, high automation degree, small floor area, and high operation efficiency.
