Description

An intelligent corridor mobile device traction chassis

technical field

The utility model relates to a stair lifting system, in particular to a traction chassis of an intelligent corridor moving device.

Background technique

Many old communities need to install stair lifts because there are many elderly people or residents with disabilities. At present, the stair lifts at home and abroad can be roughly divided into three types: seat type stair lifts, standing platform type stair lifts and wheelchair platform type stair lifts. .

The chair-type stair lift is mainly a barrier-free facility that provides convenient up and down stairs services for people with disabilities. Seat stair lifts take up a lot of space in the stairs. If it is installed in the narrow stairs of the old residential area, not only other pedestrians cannot pass normally, but the knees of the seated person almost touch the wall. It is very inconvenient to go up and down the stairs, and the price is expensive. The capacity is small and the waiting time is long. For example, it takes 20 minutes to go up and down on the 7th floor.

The frame of the standing platform stair lift is made of stainless steel with a thickness of 14 cm. The frame components are installed close to the side of the corridor wall and fixed on the steps, like a thickened wall panel. Installing against the wall will directly use The frame extends to the door of the residents, which makes it inconvenient for the residents to walk together, and the stairs take up a lot of space, which has a certain impact on moving; and the driving device is fixed at one end of the elevator, and the pulley block and steel wire rope drive the load-carrying device and passengers to rise or fall along the running guide rail. It is easily damaged in long-term use, and it is not easy to repair when it is enclosed in the frame assembly. Moreover, because the elevator adopts a fully enclosed structure, the shell needs to be customized, so it cannot be mass-produced and applied to various communities, and each floor requires two sets of motors and control systems, which are expensive.

Wheelchair platform stairlifts are mainly used to provide convenient up and down stairs services for disabled persons (including other mobility-impaired persons) in wheelchairs. Wheelchair platform stair lifts are specially designed for the disabled, the working platform is large, the stairs take up more space, and the guide rails need to be customized, so they cannot be mass-produced and applied to various communities, and the price is expensive.

Based on the defects of the above three types of lifts, if you want to occupy less space in the stairs, you can install the motor not on the carrying trolley but on the corridor platform, and then connect the transmission device to drive the carrying trolley. The radial distance between the driving sprocket shafts is very large. When the distance between the stair handrails is small, the axial distance between the driving sprocket shafts is also small. The distance in the direction is relatively large, and the eccentricity is limited, which cannot meet the needs of the corridor elevator.
