Description

Technical Field

[0001] This utility model relates to the field of railway vehicle maintenance and production technology, specifically a conveying system consisting of a gantry robot and longitudinal tracks. Background Technology

[0002] Currently, in the wheel and axle workshops of railway depots across the country, although each workshop has 2-3 parallel, independent, and basically identical maintenance lines arranged longitudinally along the workshop building, each line consists of longitudinal ground tracks and various maintenance equipment, none of them have a wheelset buffer area that can be shared by all maintenance equipment in their overall layout. For the maintenance equipment on each longitudinal track, they are arranged in series, and there are relatively long longitudinal ground tracks between each piece of equipment on the same work line to buffer wheelsets at a certain workstation; however, these ground tracks on the work line cannot be shared by all maintenance equipment.

[0003] When a piece of maintenance equipment malfunctions, its corresponding wheelset buffer section is far from meeting the production scheduling's demand for wheelsets. Similarly, wheelset buffer sections on other work lines may be idle. Furthermore, due to the large area occupied by the ground turntable, there are very few transverse tracks in the wheel and axle workshops of all railway depots. This makes the transfer of wheelsets between longitudinal tracks extremely difficult. If a piece of equipment on a longitudinal track malfunctions, all equipment on that longitudinal track may have to stop production.

[0004] Although, in theory, the problem of parallel maintenance of wheelsets between longitudinal tracks can be solved by adding turntables and transverse tracks, it is difficult to implement in practice due to the limitation of workshop area.

[0005] Another drawback of the existing technology is that the transportation of wheelsets between various maintenance stations is mainly achieved by manually pushing the wheelsets to roll on the ground track, resulting in very low efficiency in wheelset maintenance and utilization of maintenance equipment, and very high labor intensity for workers. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a conveying system composed of a gantry robot and a longitudinal track to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A workshop 1 in the wheel and axle workshop of a railway vehicle depot or vehicle factory includes a wheelset 1A, two or three longitudinally arranged tracks 1X, several maintenance equipment 2, a wheelset buffer area 3, and a gantry robot 4. Various maintenance equipment 2 are arranged in the order of the work process on each longitudinal track 1X. A transition track 5 is provided between two adjacent maintenance equipment 2 on the same longitudinal track 1X. The gantry robot 4 is used to transport the wheelset 1A between the wheelset buffer area 3 and the transition track 5.

[0008] As a further embodiment of this utility model: the longitudinal track 1X includes a track conveying device 6, which enables the wheelset 1A to run and stop on the longitudinal track 1X.

[0009] As a further embodiment of this utility model: the track conveying device 6 includes a dialer 6A, a stopper 6B and a backstop 6C. The dialer 6A enables the wheelset 1A to run on the longitudinal track 1X, the stopper 6B prevents the wheelset 1A from moving forward on the longitudinal track 1X, and the backstop 6C prevents the wheelset 1A from moving backward on the longitudinal track 1X.

[0010] As a further embodiment of this utility model: the gantry robot 4 includes a large trolley 4A, a small trolley 4B, a lifting device 4C, and a gripper 4D. The large trolley 4A includes a transverse track 4AY; the gripper 4D of the gripping wheel pair 1A is installed on the lifting device 4C, and the lifting device 4C is installed on the small trolley 4B; the small trolley 4B runs on the transverse track 4AY, and the large trolley 4A runs longitudinally within the factory building 1.

[0011] As a further embodiment of this utility model: the factory building 1 includes a steel platform 7, the steel platform 7 includes an opening 7A and a safety cover 7B, the safety cover 7B can cover the opening 7A located above the transition track 5.

[0012] As a further embodiment of this utility model: the wheelset buffer area 3 includes a steel platform buffer area 3A located above the steel platform 7.

[0013] In summary, compared with existing technologies, the main features of this utility model are: 1) It provides a wheelset buffer area that can be shared by all maintenance equipment, and the wheelset buffer area can be arranged nearby on the steel platform, thus greatly reducing the floor space; 2) Since the gantry robot does not need to rotate 90 degrees to grasp the wheelset, and even if the wheelset needs to rotate 90 degrees, it can rotate in the air after leaving the ground, so its floor space is very small; 3) Since the transverse tracks are connected in parallel, when only one maintenance equipment is arranged on each of the 2-3 transverse tracks in the same process, the front and rear plate chain conveyors can be used to achieve the parallel arrangement of 2-3 maintenance equipment with the same configuration in the same process; when multiple maintenance equipment are arranged on the same transverse track, a transition track is arranged between adjacent maintenance equipment, and the gantry robot picks up and places wheelsets on the transition track, so that all maintenance equipment is arranged in parallel, thus forming a truly fully flexible production line. Therefore, the main advantages of this utility model are: low labor intensity for workers, high degree of automation, small floor space, and high operating efficiency. Attached Figure Description
