Description
Technical Field
The utility model relates to an electric traction type multifunctional stair-climbing wheelchair, which belongs to the improvement of a wheelchair structure.
Background
At present, conventional stair climbing wheelchairs are all crawler-type wheelchairs, are high in gravity center and unstable, need auxiliary personnel for protection or operation, otherwise are easy to fall down to cause accidents, and are low in fault tolerance rate.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an electronic multi-functional stair wheelchair of climbing of towed, do not need conventional auxiliary personnel, just can conveniently climb stair, use safe and reliable more.
The utility model aims at realizing the electric traction type multifunctional stair climbing wheelchair, which comprises a wheelchair body, wherein a crawler traveling device and a lifting mechanism of the crawler traveling device are arranged under the wheelchair body, traveling wheels are respectively arranged on two sides of the wheelchair, an electric capstan is arranged under the bottom surface of the front part of the wheelchair, a traction rope is wound on the electric capstan, the free end of the traction rope is connected with a fixed ring fixedly arranged on the wall of the inclined opposite surface of a building stair opening, the lifting mechanism is an electro-hydraulic push rod type lifting mechanism or a telescopic rod type manual lifting mechanism, the lifting mechanism is arranged under the rear part of the wheelchair body, and two ends of a driven rotating shaft at the rear part of the crawler traveling device are respectively arranged at two ends of the lower part of the lifting mechanism through bearings; the two side walls of the wheelchair are respectively and vertically provided with a guiding and positioning cylinder, the wheel shaft between the two walking wheels is respectively and vertically and fixedly provided with a guiding shaft, the guiding shaft is sleeved in the guiding and positioning cylinder in a sliding fit manner, and the depth of the guiding shaft entering the guiding and positioning cylinder is limited by a pin shaft which is horizontally inserted between the guiding shaft and the guiding and positioning cylinder.
The device is based on an electric wheelchair, the walking wheels are lowered down when walking on flat ground or at a low gradient, the crawler walking device is lifted up, and the wheelchair is driven to move by the rotation of the walking wheels, so that the device is light and fast; when going upstairs and downstairs, the wheelchair is driven by the simultaneous movement of the crawler traveling device and the traction rope, the walking wheels are lifted, the telescopic traction rope can play a role of a safety protection rope, conventional auxiliary personnel are not needed, and the wheelchair is safer and more reliable.
This kind of multi-functional building wheelchair that climbs of electronic towed adopts and increases gauge electric caterpillar, and the chassis is stable to installation electric capstan, hang directional haulage rope and pull the wheelchair upstairs after solid fixed ring, utilize track and haulage rope simultaneous action when going downstairs, dual protection, consequently fault-tolerant rate when going upstairs is high, the accident hardly appears. The utility model is used for unable walking crowd is particularly suitable for alone, and nobody accompanies, the personnel of stair, outdoor leisure about need. Before use, a fixing ring is required to be arranged on the wall opposite to the stair opening and used for fixing the traction rope hook. The fixing ring is arranged at a proper position in a building with stairs, and the multifunctional stair climbing wheelchair brings great convenience to people who cannot walk after popularization.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic view of the usage state of the present invention;
fig. 2 is a rear view of the present invention.
Detailed Description
An electric traction type multifunctional stair climbing wheelchair comprises a wheelchair body, as shown in figures 1 and 2, a crawler traveling device 5 and a lifting mechanism 15 of the crawler traveling device are mounted below the wheelchair body 3, traveling wheels 14 are respectively arranged on two sides of the wheelchair, an electric winch 6 is arranged below the bottom surface of the front portion of the wheelchair, a traction rope 2 is wound on the electric winch 6, and the free end of the traction rope 2 is connected with a fixing ring 1 fixedly arranged on an oblique opposite wall of a building stair opening.
