Urban public transport automation obstacle-free platform

Abstract

An automatic barrier free platform for the public traffic of the city belongs to the mechanical automation manufacture field. The platform comprises an inverting guide rail system, a scissors elevating system, a manned carriage system, a PLC automatic control system, wherein a base (12) of the scissors elevating system is combined with installation conditions, the worm gear shaft (2) of the inverting guide rail system is passed through the lateral hole of a U-shaped footstock (7) of the scissors elevating system, and the manned carriage system is directly placed on the U-shaped footstock (7).When the scissors elevating system is expanded, a carriage (17) is moved in back and forth in a passage which is formed by the footstock (7) and an inverting guide rail (1), and the carriage (17) is covered with the inverting guide rail, and is covered in the scissor elevating system when the scissor elevating system is folded. The invention has electromechanical combination, high automation and simple and convenient operation. The humanity design realizes the various movement ways, realizes the accurate abutting joint between the barrier free platform and buses, which can be directly appliedin the Olympic Games of 2008.

Description

technical field [0001] The utility model relates to an automated barrier-free platform for urban public transport, which belongs to the field of mechanical automation manufacturing. Background technique [0002] At present, domestic and foreign solutions for the disabled to get on and off the bus are concentrated on the research and design of two categories: "barrier-free bus" and "vehicle system", but these two categories of solutions have their limitations: [0003] 1. Barrier-free buses have the following problems: [0004] A. Barrier-free buses with low chassis have poor passability [0005] It is reported that the chassis S height of the first barrier-free bus in Beijing (Beijing Station to Xizhimen) is 170mm. However, such a low chassis poses a big problem in the passability of the bus. In the actual operation process, it is easy to encounter stones or small slopes, and the phenomenon of dragging the bottom is inevitable. [0006] B. Barrier-free buses are expensive...

AI Technical Summary

Problems solved by technology

Due to the need to change the entire chassis system and add a controllable suspension system with a complex structure, the technology is difficult and the cost is very expensive, and the price of the bus is several million

[0014] B. The layout of the on-board system is restricted by the space of the car itself, the space layout is difficult, and it is easy to conflict with the space layout of the chassis and the daily use mechanism

At the same time, the layout of the entire car body needs to be changed, and the cost is greatly increased

[0015] C. The electronic control system is complex
