Description

A load-carrying stair climbing device

technical field

The utility model relates to the technical field of stair climbing devices, in particular to a stair climbing device for carrying objects.

Background technique

At present, when express delivery, the goods are often placed at the gate of the community, and the consignee can pick it up by himself. If the consignee is an elderly person or the goods are heavy, the transportation from the gate of the community to the consignee's home becomes a problem. In addition, some old communities are mostly multi-storey buildings without elevators. It is more difficult to carry goods upstairs. When people carry heavy objects and climb stairs, they often feel powerless. In the process of climbing stairs with loads, it is "like walking on the ground". The principle of the existing load stair climbing device, such as the crawler stair climbing device, is similar to that of a tracked armored personnel carrier or a tank, and it adopts a more continuous walking mode than the star wheel mechanism, and the transmission efficiency is relatively high. However, its biggest disadvantage is that the resistance is large when walking on flat ground, the movement is not flexible, and it is easy to damage the stairs when climbing stairs.
