An auxiliary system for wheelchairs crossing overpasses

Abstract

The invention discloses a wheelchair assistance system for crossing overpasses. The wheelchair assistance system comprises a support I and a support II. The support I and the support II are both rectangular frames. A frame in the long axis direction of the support I and a frame in the long axis direction of the support II are correspondingly connected to each other, forming an X-shaped structure as a whole. At least one driving friction wheel is provided at both ends of the longitudinal direction of the support I, and at least one driven friction wheel is provided at both ends of the longitudinal direction of the support II; the X-shaped structure is used to be clamped on the guide rail. The driving friction wheel at one end of the support I and the drive friction wheel at one end of the support II are distributed and can move on the front of plate of a guide rail. The driving friction wheel at the other end of the support I and the drive friction wheel at the other end of the supportII are distributed and can move on the back of plate of a guide rail. The assistance system effectively reduces the cost of installation and maintenance. The traction device can be directly installedon overpass guardrails, and the station space is small and does not hinder the normal passage of pedestrians.

Description

technical field [0001] The invention relates to the technical field of lifting traction devices, in particular to an auxiliary system for wheelchairs crossing overpasses. Background technique [0002] Pedestrian bridges are convenient for people to cross the street and reduce urban road congestion, but it is inconvenient for disabled people traveling in wheelchairs to cross the street. At present, the pedestrian bridges in most cities are not equipped with auxiliary devices for wheelchairs to get on and off the bridges. Disabled people in wheelchairs often have to go to a large intersection with a zebra crossing far away to cross the street. There are many places that need to be improved. [0003] Some pedestrian bridges in many cities are equipped with pedestrian lifting devices, which are mainly divided into the following two categories: [0004] 1) Pedestrian bridges with escalators: This kind of pedestrian bridges are equipped with electric escalators at both ends of th...

AI Technical Summary

Problems solved by technology

However, there are problems such as large space occupation, high energy consumption and high maintenance cost.

If you want to install a vertical lifting device similar to an elevator, you need to occupy part of the sidewalk space, especially some pedestrian bridges are erected in the old city, and the sidewalks are very narrow, so it is impossible to install this vertical lifting device; The elevator needs at least one 10kw traction motor, and it is installed on the pedestrian bridge with a large flow of people. It works at almost full load for 10 hours a day and consumes at least 100 kwh of electricity every day.
