Lifting drive device for manned stair climbing device

Abstract

The invention relates to a lifting driving device of a man-riding stair climbing device. The device comprises the lifting driving device is independently installed below the back side of each stair and arranged between the adjacent lower-layer steps and the upper-layer steps, the lifting conveying device is arranged below the lifting driving device and used for carrying out displacement between the adjacent lower-layer step and the upper-layer step, the lifting driving device comprises an auxiliary connecting spline shaft, wherein the upper end of the auxiliary connecting spline shaft is coaxially connected with an output gear shaft of the main driving motor, an auxiliary lifting push rod arranged at the lower end of the side auxiliary supporting arm, the auxiliary lifting support arm is horizontally arranged on a nut seat of the auxiliary lifting push rod, the auxiliary lifting support arm is connected with the auxiliary lifting support arm, the auxiliary connection transition splinesleeve is connected with the auxiliary lifting support arm, an inner spline hole which is arranged in the auxiliary connection transition spline sleeve and is sleeved on the auxiliary connection spline shaft and is used for being connected with an auxiliary power source. The device is reasonable in design, compact in structure and convenient to use.

Description

technical field [0001] The invention relates to a lifting drive device of a manned stair climbing device. Background technique [0002] At present, there are many kinds of wheelchairs for the disabled on the market. Most of the wheelchairs are based on ordinary wheelchairs. In order to better meet the needs of the disabled to take care of themselves, a variety of functions have been added, such as the function of defecation and defecation, Electric drive function, wheelchair lifting function, etc. These improvements have greatly met the needs of the disabled in many aspects of life besides walking. However, when some patients sit in a wheelchair for a long time, the hips and spine will suffer from the same sitting posture for a long time. People with excessive body pressure and cardiopulmonary dysfunction will increase intra-abdominal pressure due to long-term non-standing, causing abdominal distension, abdominal pain, nausea and vomiting. In view of the above phenomenon, i...

Problems solved by technology

Governments at all levels are also trying to find a way to solve this problem, especially Guangzhou, Shanghai, Beijing and other places are piloting the scheme of installing box elevators in old multi-storey houses, but during the pilot process, it is found that the old multi-storey Adding box-body elevators to residential buildings has complex approval procedures, unapproved land area occupied by the shaft, high renovation costs, long construction period, and differences in opinions arising from unequal benefits for low-rise and high-rise residents. There are a certain degree of conflicts in the building codes and other series of problems, which make the pilot schemes continue to be stranded
