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.

Embodiment 1

[0041] This embodiment provides a traction device, including a bracket I1 and a bracket II2, the bracket I1 includes two long square steels and a short square steel, the two rectangular steels are arranged parallel to each other and connected by short square steels, It is similar to an I-shaped structure; the bracket II2 includes two long square steels and one short square steel, and the two long square steels are arranged in parallel to each other and connected by short square steels, forming a similar I-shaped structure. The distance between the two rectangular steels of the support II2 is smaller than the distance between the two rectangular steels of the support I1, the support I1 passes through the support II, the two rectangular steels of the support I1 and the two long steel bars of the support II2 The square steel is fixedly connected to each other, and the overall structure is X-shaped. Both ends of the long axis direction of the bracket I1 are provided with two activ...

Embodiment 2

[0043] Further improvement on the basis of Example 1, if the two rectangular steels of bracket I1 are marked as A1 and A2 respectively, and the two rectangular steels of bracket II2 are marked as B1 and B2 respectively, one rectangular steel of bracket I1 The steel A1 is hingedly connected to one rectangular steel B1 of the bracket II2, the other rectangular steel A2 of the bracket I1 is hingedly connected to the other rectangular steel B2 of the bracket II2, and the connecting line of the two hinged connection points is used as the axis, The X-shaped structure takes the axis as the axis to open and close and rotate. The overall structure is X-shaped, similar to the structure of scissors

[0044] The two frames of the bracket I1 and the bracket II2 are connected by a tension spring, specifically, the axial ends of the rectangular steel A1 and the axial ends of the rectangular steel B1 are connected by a tension spring, and the rectangular steel A2 is connected by a tension spr...

Embodiment 3

[0046] Further improvement on the basis of Embodiment 2, guide wheels 6 are provided at both axial ends of the bracket I1 and the bracket II2, and the guide wheels 6 are used for walking on the upper and lower end surfaces of the guide rail 5 . Sprocket 7 is arranged on the shaft section of the active friction wheel 3 at both ends of the long axis direction of the frame I1, which is connected with the sprockets at both ends of the frame I1 by the same chain, and the motor drives the sprocket to rotate, thereby driving the frame. All the driving friction wheels 3 at both ends of the long axis direction of I1 rotate synchronously.

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...
