Description

Technical Field

[0001] The invention relates to the technical field of railway vehicle maintenance and production, in particular to an equipment process layout and a truss robot used in a railway axle workshop. Background Art

[0002] At present, in the wheel axle workshops of various railway depots and vehicle factories across the country, the process layout of the wheelset production line is basically composed of 2-3 relatively independent operation lines, that is, arranged in series operation, and some operation areas of the wheelset (such as wheel turning, unloading and pressing, etc.) are relatively scattered, commonly known as the "ground stall" layout; moreover, the ground rails in the workshop are both the carrier for wheelset transportation and the route for wheelset operation, which results in a series of problems such as large operation area of ​​the wheel axle workshop, large investment in equipment and track construction, high labor intensity of workers, and low production efficiency. The specific situation is as follows: 1) Equipment duplication, because the equipment configuration is the same on each production line. For example, although a process only needs one piece of equipment to meet production needs, it is still necessary to configure one piece of the same equipment on each production line.

[0003] 2) The amount of ground track laid is large and the wheelset transportation route is long; the transportation of wheelsets between production stations mainly relies on manpower, so the transportation efficiency of wheelsets and the utilization rate of tooling equipment are very low, and the labor intensity of workers is very high.

[0004] 3) Since some production operation areas and equipment are relatively scattered, there are many production operation lines and the operation lines are long, the maintenance production of wheelsets occupies a very large area.

[0005] 4) Since there are usually only two cranes in a factory, each work area has to compete for their use, which often causes waiting for work.

[0006] 5) Since the tooling equipment on each independent wheelset production line is arranged in series, as long as one device fails, it will affect the production of the entire production line.

[0007] 6) Since the wheelsets have to roll along the operating line on the ground rails, they cannot be staggered or cross-stored on the ground rails, let alone stored densely, resulting in very few wheelsets stored in the production area of ​​the axle workshop.

[0008] 7) The ground rails are divided into several isolated "line segments" by the wheelset production equipment. Although wheelsets can be stored on the "line segments", each "line segment" can only store the wheelsets required by the previous equipment station of the "line segment", and cannot store the wheelsets required by other equipment stations. Summary of the invention

[0009] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an equipment process layout and a truss robot for a railway wheel and axle workshop to solve the problems mentioned in the above background technology.

The three-station inclined rail 7D1 is higher at the starting end located at the workpiece placing position 7A than at the tail end located at the workpiece taking position 7C. The rear stopper 7D2 is located at the workpiece placing position 7A, and the front stopper 7D3 is located at the three-station working position 7B.

[0015] As a further solution of the present invention: the two-station working position 6B or the three-station working position 7B includes a lifting and adjusting device 67. The wheel set 1A is lifted by the lifting and adjusting device 67, and its height is adjusted so that the wheel set 1A is clamped on the two-station device 6 or the three-station device 7.

[0016] As a further solution of the present invention: the wheel set 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 wheel set 1A.

[0017] As a further solution of the present invention: the workshop 1 includes a wheel set inspection area 1C and a parallel workshop 12 adjacent to the pre-inspection operation area 2 but not in the same bay. The plate chain conveyor 8 in the parallel workshop 12 includes a horizontally arranged horizontal conveyor 9, and the wheel set inspection area 1C in the parallel workshop 12 includes a parallel inspection entrance 1C2; The conveyance of the wheel set 1A from the pre-inspection operation area 2 to the parallel inspection entrance 1C2 is realized by the horizontal conveyor 9.

[0020] Compared with the prior art, the main features and advantages of the present invention are as follows: 1) Cancel the ground track for the running of the wheelset, and arrange the production equipment in parallel, which belongs to the flexible production mode.

[0021] 2) The conveyance of the wheelset between various equipment, between the wheelset storage positions, and between the equipment and the wheelset storage positions is mainly achieved by using a truss robot.

[0022] 3) The layout between the wheelset and the axle can have pedestrian passages and equipment areas on both sides, and a wheelset storage area in the middle. An integrated and embedded platform can be set in the wheelset storage area. The length direction of the wheelset storage is parallel to the length direction of the space between the wheelset and the axle, and can be staggered and cross-arranged; this platform has the dual functions of wheelset storage and personnel emergency passage.

[0023] 4) When the truss robot fails, the operating personnel can stand on the platform in the storage area and carry out emergency treatment with the help of the workshop overhead crane.

[0024] 5) Since the wheelset is conveyed in the air, the wheelsets can be densely stored in the ground storage area, which can greatly increase the storage capacity of the wheelsets, not only meeting the production needs but also facilitating the call management of the wheelsets.

[0025] 6) Since the production equipment of the wheelset is arranged in parallel, the wheelset storage area has actually become a unified large-capacity wheelset storage shared by various wheelset working stations' equipment. Even in extreme cases, it can become a wheelset storage exclusive to a certain tooling equipment. For example, when all the bearing running-in test equipment of the wheelset fails, the entire storage area can only store one type of wheelset to be run-in tested, so as not to affect the operation of the previous process.

[0026] In summary, the main advantages of the present invention are: the process layout of the production equipment and operation lines in the railway wheelset workshop is reasonable, with a small floor area, high automation, high production efficiency, especially the transportation efficiency of the wheelset and the utilization rate of the production equipment are significantly improved, and a basic platform is built for the future digital and intelligent wheelset workshop.
