Technical Field

[0001] The utility model relates to the technical field of the production of parts of rail vehicles, and particularly relates to a production line for a ramp for rail transit vehicles. Background Art

[0002] The barrier-free ramp is a tool for assisting passengers using wheelchairs and baby carriages to get on and off the train. When in use, the staff unfolds the ramp and sets it up between the platform and the carriage, then the height difference and gap between the platform and the carriage can be leveled, so that the wheelchair and the baby carriage can be smoothly pushed on and off, and it is safer and more reassuring for passengers to enter and exit the carriage.

[0003] The barrier-free ramp is usually a flat structure made of aluminum alloy profiles, with a retractable or foldable mechanism and relevant warning signs installed. At present, during the production and assembly process of the ramp, it is mostly in fixed workstations, and at least one operator is equipped in each workstation. Each workstation independently completes the assembly of a complete product. The disadvantages of this production method are as follows:

[0004] First, the production site occupies a large area and requires a large number of operators. Since the product parts are scattered, the efficient and orderly flow of the product is slow, and the production and management costs are relatively high.

[0005] Second, manual assembly is limited by the proficiency of the operators. The assembly efficiency of each workstation is different, and the product quality control is also different. Therefore, the consistency of the product is poor.

[0006] Third, there is a problem of missing items in manual assembly. There are often problems of missing parts in the product, which requires rework and repair, and the product quality and production efficiency cannot be guaranteed.

[0007] In summary, the existing manual assembly method of the ramp needs to be improved. Content of the Utility Model
