Abstract

A stairs-climbing trolley comprises a compartment, a bottom plate and wheels disposed under the bottom plate. A carrier is fixed to the lower end of the compartment. Two sides of the tail end of the carrier are provided with a pair of lugs. The tail end of the bottom plate is movably connected with the lugs of the carrier through a rotating shaft. The middle of the bottom end of the carrier is connected with the bottom plate through a telescopic bar. Each wheel structure comprises a central spindle and wheel sets, each which is composed of three planetary wheels and two of which are arranged on two sides of the central spindle; the three planetary wheels are evenly distributed at 120-degree angles around the central spindle. The stairs-climbing trolley can travel on the horizontal roads and can also climb a slope or stairs; during climbing the stairs, the trolley can keep articles in the compartment stably and rarely turned over; the stairs-climbing trolley is simple in structure and low in manufacturing costs and can help people climb upstairs and downstairs with less labor consumed and conveniences brought.

Description

technical field [0001] The invention relates to a transport machine, in particular to a trolley capable of climbing stairs. Background technique [0002] With the rapid development of social economy, more and more people live in buildings. However, ordinary residential buildings do not have elevators, so it will be very laborious for residents to carry large goods such as bottled mineral water and gas tanks upstairs. In addition, due to the slope of the corridor, it is easy to cause some goods to overturn during the hauling process. Therefore, moving items up and down the stairs has become a significant problem, and a means of transportation is needed to solve this difficulty. Contents of the invention [0003] The object of the present invention is to provide a trolley capable of climbing stairs. The trolley can not only walk on a horizontal road but also climb slopes or stairs, and can keep the stability of the articles in the compartment difficult to overturn when clim...
