Description

Technical Field

[0001] This utility model relates to the field of railway vehicle maintenance and production technology, specifically a process layout of equipment and a gantry robot for railway wheel and axle workshops. Background Technology

[0002] Currently, in the wheel and axle workshops of various railway depots and rolling stock plants across the country, the process layout of wheelset production lines is basically composed of 2-3 relatively independent work lines, i.e., arranged in series. Some work areas of wheelsets (such as wheel turning, unloading, and pressing) are relatively scattered, commonly known as a "street stall" layout. Moreover, the steel rails on the workshop floor serve as both the carrier for transporting wheelsets and the route for wheelset operations. This results in a series of problems in wheel and axle workshops, including large operating area, high investment in equipment and track construction, high labor intensity for workers, and low production efficiency. The specific situation is as follows:

[0003] 1) Redundant equipment configuration, because the equipment configuration is the same on every production line. For example, although a certain process only requires one machine to meet production needs, one of the same machines is still configured on each production line.

[0004] 2) The ground track is extensive and the wheelset transport route is long. The transport of wheelsets between various production stations mainly relies on manual labor. Therefore, the transport efficiency of wheelsets and the utilization rate of tooling equipment are very low, and the labor intensity of workers is very high.

[0005] 3) Because some production areas and equipment are scattered, and there are many production lines and long operation routes, the maintenance and production of wheelsets requires a very large area.

[0006] 4) Since there are usually only two overhead cranes in the factory, these two cranes are often contested by various work areas, which often causes work to wait.

[0007] 5) Since the tooling equipment on each independent wheelset production line is arranged in series, if any one piece of equipment fails, it will affect the production of the entire production line.

[0008] 6) Because wheelsets need to roll along the work line on the ground rails, they cannot be stored separately or crosswise on the ground rails, let alone densely, resulting in very few wheelsets stored in the production area of ​​the wheel and axle workshop.

[0009] 7) The ground rails are divided into several isolated "segments" by the wheelset production equipment. Although wheelsets can be stored on these "segments", each "segment" can only store the wheelsets required by the preceding equipment station and cannot store the wheelsets required by other equipment stations. Utility Model Content

[0010] In view of the problems existing in the prior art, the purpose of this utility model is to provide an equipment process layout and gantry robot for railway wheel and axle workshop, so as to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, this utility model provides the following technical solution: In a railway vehicle depot or vehicle factory, the wheel and axle workshop building 1 includes wheelsets 1A, columns 1B, overhead tracks 1X, wheelset inspection area 1C, wheelset conveying system 1D, and pre-inspection work area 2.

[0016] As a further embodiment of this utility model: the equipment process layout and gantry robot for railway wheel and axle workshop is characterized in that the two-station workstation 6B includes a lifting and adjusting device 67, which lifts the wheelset 1A and adjusts its height so that the wheelset 1A is clamped on the two-station equipment 6.

[0017] It should be noted that the three-station workstation 7B can also be equipped with a lifting and adjusting device 67. The lifting and adjusting device 67 can lift the wheelset 1A and adjust its height so that the wheelset 1A can be clamped on the three-station equipment 7.

[0018] As a further embodiment of this utility model: the wheelset conveying system 1D includes a plate chain conveyor 8, and the running direction of the plate chain conveyor 8 is the length direction of the wheelset 1A.

[0019] As a further embodiment of this utility model: the factory building 1 includes a parallel factory building 12 that is adjacent to the wheelset inspection area 1C and the pre-inspection work area 2, although they are not in the same span. The plate chain conveyor 8 in the parallel factory building 12 includes a transversely arranged transverse conveyor 9. The wheelset inspection area 1C in the parallel factory building 12 includes a parallel inspection entrance 1C2.

[0020] The transport of wheelset 1A from the pre-inspection work area 2 to the parallel inspection entrance 1C2 is achieved by the transverse conveyor 9, which includes a plate chain entrance 9B and a wheel puller 9C. The transport of wheelset 1A from the pre-inspection work area 2 to the plate chain entrance 9B is also achieved by the gantry robot 5. The transport of wheelset 1A from the plate chain conveyor 8 to the parallel inspection entrance 1C2 is achieved by the wheel puller 9C.

[0021] As a further embodiment of this utility model: the plate chain conveyor 8 includes a high-level plate chain conveyor 8A located at the inlet 2A and a low-level plate chain conveyor 8B located at the outlet 2B. The high-level plate chain conveyor 8A and the low-level plate chain conveyor 8B are respectively located at the placement position 7A and the picking position 7C of the three-station equipment 7.

[0022] As a further embodiment of this utility model: the wheelset 1A includes a truck wheelset, the wheelset storage area 4 includes a pedestrian platform 4B, the pedestrian platform 4B includes several large treads 4B1, small treads 4B2 and axle grooves 4B3, the large treads 4B1 are located between the axles of adjacent wheelsets 1A, and the small treads 4B2 are located between the axle ends of two adjacent wheelsets 1A; the axle grooves 4B3 located in the storage position 4A are used to place the wheelset 1A.

[0023] Compared with the prior art, the main features and advantages of this utility model are as follows:

[0024] 1) The ground tracks for wheelset travel are eliminated, and the production equipment is arranged in parallel, which is a flexible production mode.

[0025] 2) Wheelset transportation between different devices, between wheelset storage locations, and between devices and wheelset storage locations is mainly achieved by using gantry robots.

[0026] 3) The layout between the wheels and axles can have pedestrian walkways and equipment areas on both sides, with the wheelset storage area in the middle. An integrated, embedded platform can be installed in the wheelset storage area, with the length direction of the stored wheelsets parallel to the length direction between the wheels and axles, and they can be staggered or crossed; this platform serves the dual function of wheelset storage and emergency personnel passage.

[0027] 4) When the gantry robot malfunctions, the operator can stand on the platform in the storage area and use the workshop crane for emergency handling.

[0028] 5) Since the wheelsets are transported in the air, they can be stored densely in the ground storage area, which can greatly increase the storage capacity of the wheelsets, not only meeting production needs but also facilitating the management and dispatch of the wheelsets.

[0029] 6) Since the wheelset production equipment is arranged in parallel, the wheelset storage area has actually become a unified large-capacity wheel storage warehouse shared by all wheelset workstations. In extreme cases, it can even become a wheel storage warehouse exclusively for a certain tooling equipment. For example, when all the wheelset bearing break-in testing equipment fails, the entire storage area can store only one type of wheelset to be broken in and tested, so as not to affect the operation of the previous process.

[0030] In summary, the main advantages of this utility model are: the production equipment and operation lines in the railway wheel and axle workshop are reasonably arranged, occupy a small area, have a high degree of automation, and have high production efficiency. In particular, the transportation efficiency of wheelsets and the utilization rate of production equipment are significantly improved, and a basic platform is built for the future intelligent wheel and axle workshop.
