Power-assisted transferring trolley capable of climbing stairs

Abstract

The invention relates to a power-assisted transferring trolley capable of climbing stairs. The power-assisted transferring trolley capable of climbing stairs comprises a bearing device used for bearing goods, a stair climbing device capable of achieving stair climbing through track movement, a flat ground and stair converting device used for adjusting the working angle between the bearing device and the stair climbing device, a control device used for controlling the working states of the stair climbing devices and the flat ground and stair converting device, and a power source. The bearing device and the stair climbing device are connected through the flat ground and stair converting device. The flat ground and stair converting device comprises a telescopic push rod, a push rod cylinder and a push rod driving motor. The push rod driving motor provides power for the operation of the push rod cylinder. The operating state of the push rod cylinder determines the telescopic length of the push rod. The power-assisted transferring trolley capable of climbing stairs has a flat road traveling function and a stair climbing function, and the movement speed and direction of the trolley can be adjusted; and in addition, the power-assisted transferring trolley is simple in structure and convenient to operate, the labor intensity of operators is greatly relieved, and the working efficiency and safety are improved.

Description

technical field [0001] The invention relates to the field of power-assisted transporting trolleys, in particular to a stair-climbing power-assisted transporting trolley. Background technique [0002] In recent years, with the continuous acceleration of my country's urbanization process and the continuous increase of the proportion of cities and towns, the floors of housing in various places are getting higher and higher, and there are great difficulties in the handling of various items. And with the development of transportation service industries such as express delivery and moving, especially the delivery of more and more diversified items in the express delivery industry, many large goods need to be moved, and there are great limitations in manpower and freight elevators. At this time, a A convenient and flexible stair-climbing assisting device to complete the handling of large items. In some areas and complex terrain where mechanized equipment is not popular, a small an...
