Power stair climbing vehicle

Abstract

The invention provides a power stair climbing vehicle, and aims to solve the problems that the loading stair climbing vehicle is low in adaptability to stairs with different gaps and heights and high in possibility of slipping and falling in the stair climbing process, and is incapable of reliably, effectively and automatically climbing stairs. The power stair climbing vehicle comprises a power device, a stair climbing mechanism, a vehicle frame and a loading platform; the stair climbing mechanism is characterized in that two ends of a transmission main shaft are rotatably connected with three-support-arm star-shaped brackets; a central gear fixedly connected with the transmission main shaft is rotatably arranged at the center of each star-shaped bracket; three support arms of the star-shaped brackets are rotatably connected with inner planetary gears which are meshed with the central gears; the inner planetary gears are meshed with outer planetary gears; climbing wheels capable of synchronously rotating along with the outer planetary gears are arranged at the end parts of the three support arms of the star-shaped brackets. According to the power stair climbing vehicle, the climbing wheels can drive forwards, so that the star-shaped brackets are driven to stably and automatically climb stairs; the power stair climbing vehicle is low in possibility of slipping and falling, is capable of continuously driving forwards or upwards along the stair surfaces when the stairs are large in span, and is safe and reliable; the manpower is saved.

Description

technical field [0001] The invention relates to a load carrying device, in particular to a powered stair climbing vehicle suitable for carrying heavy objects on stairs. Background technique [0002] People need to use two-wheeled or three-wheeled trolleys to carry building materials in a small area during the construction and decoration of houses, parks, etc., but it will cause inconvenience when they encounter steps on the road, and they need to apply upward push or pull to overcome The gravity of the load moves upwards, especially in the case of transporting heavy objects upwards through stairs, the trolley cannot play a role, and it is completely carried by manpower. At present, in order to enable the trolley to climb stairs, the rollers of the trolley are designed as three-arm star-shaped rotating brackets, and the three ends of the bracket are respectively provided with rollers. The bracket uses the rollers as the supporting point to turn over and change the fulcrum to...
