Wheel and track combined stair climbing cargo transporter

Abstract

The invention discloses a wheel and track combined stair climbing cargo transporter. The wheel and track combined stair climbing cargo transporter comprises a first frame and a second frame which arearranged vertically as well as a first driver and a hinging assembly which are arranged between the first frame and the second frame in the driving direction of the cargo transporter, wherein two endsof the first driver are hinged with the first frame and the second frame respectively; a first wheel assembly enabling the cargo transporter to drive on the ground is arranged below the first frame;a track assembly is arranged on the second frame, a second wheel assembly connected through a position adjusting assembly is arranged below the second frame, and the first wheel assembly and the second wheel assembly are arranged forwards and backwards in the driving direction of the cargo transporter. The cargo transporter has the advantages as follows: a flat ground driving mode driven by a wheel train or a stair climbing mode realized by a track mechanism can be selected according to actual demands when cargos are transported upstairs and downstairs, meanwhile, two functions of high-speed driving on the flat ground and stable stair climbing are realized, and the problems that existing cargo transporters cannot climb stairs and have poor maneuverability are solved.

Description

technical field [0001] The invention relates to the technical field of power-assisted machinery and mechanical auxiliary devices, and in particular to a wheel-track compound type capable of climbing stairs. Background technique [0002] In our country, there are still quite a few people living in old communities without elevators. For the elderly or those with leg problems living in them, not only have certain difficulties in going up and down the stairs every day, if If you have purchased a product with a certain weight or volume, it will be more inconvenient to carry it upstairs.

Problems solved by technology

[0002] In our country, there are still quite a few people living in old communities without elevators. For the elderly or those with leg problems living in them, not only have certain difficulties in going up and down the stairs every day, if If you purchased a product with a certain weight or volume, it would be more inconvenient to carry it upstairs

At the same time, for the transporters of bulk goods and home appliances, when transporting goods for consumers in old residential areas, since there is no elevator, they often use the method of carrying or lifting, which is not only time-consuming and laborious, but also easily causes damage to the goods, causing unnecessary disputes

In order to deal with this phenomenon, old communities around the world have carried out evaluations of elevator renovation projects. However, the types of houses in old communities often have limited public space, and it is difficult to actually implement them. Rare objective conditions allow the transformation of communities, which are often difficult to adjust due to public opinion. Or the cost is too high and let it go

[0003] At present, when cargo transporters and elderly people with handicapped legs and feet are transporting items up and down the stairs, they mainly use three-planetary wheeled manpower trolleys or cargo trolleys to carry items up and down the stairs. To a certain extent, it is convenient to carry items on flat ground, but when encountering stairs or steps, not only is it not convenient for users to carry goods, but it becomes a burden for users
