An automatic stair climbing device

Abstract

The invention discloses an automatic stair climbing device. The automatic stair climbing device comprises a chassis, a carrying frame and crawler wheel assemblies arranged on the two sides of the chassis, wherein each crawler wheel assembly comprises a mounting plate, a guide wheel, a middle wheel, a rear wheel and a crawler; the front end, middle part and rear end of each mounting plate are provided with a rotatable first wheel shaft, a second wheel shaft and a third wheel shaft respectively, each guide wheel is coaxially and fixedly connected with the corresponding first wheel shaft, each middle wheel is coaxially and fixedly connected with the corresponding second wheel shaft, and each rear wheel is coaxially and fixedly connected with the corresponding third wheel shaft. The automaticstair climbing device is characterized in that a first motor is fixedly arranged on each mounting plate, drive switching mechanisms are arranged between the first motors and the second wheel shafts and the third wheel shafts, the second wheel shafts are connected with the chassis, the front end of the carrying frame is hinged to the upper end face of the chassis, and the chassis is provided with acarrying frame angle adjusting mechanism. The automatic stair climbing device has the advantages that the device climbs stairs stably and flexibly, is relatively higher in speed and cannot roll over.

Description

technical field [0001] The invention relates to equipment for climbing stairs with loads, in particular to an automatic stair climbing device. Background technique [0002] In some factories or construction sites, when carrying some small and light objects, it is usually carried by manpower, but for relatively heavy objects, it is a bit difficult for one person to carry them, and it requires two or more people to carry them at the same time. It took a lot of manpower. In order to reduce manpower, there are currently some load-carrying stair climbing devices that can replace manpower handling on the market. They can be mainly divided into two types: planetary wheel type and crawler type. The planetary wheel type has a large volume and the center of gravity is unstable during work; The motion of type stair climbing device is also not flexible enough, and speed is slower, vibration is big when climbing stairs, and easily produces overturning.
