Problems solved by technology
Among them, the crawler type has a large weight and is not flexible enough to operate, and the pressure on the edge of the stairs is relatively large when climbing stairs; the wheel group type has a wide range of motion and flexible movement, but the stability is not high when going up and down the stairs, and the center of gravity fluctuates greatly, which will make the user feel uncomfortable. Feeling uncomfortable; the walking style has high requirements on the control system, complex operation, small range of motion, and slow movement
Especially some automatic stair-climbing auxiliary devices currently on the market have complicated control and high cost, and are not suitable for ordinary freight companies to use

The invention discloses a stair climbing assisting device for freight transportation. The stair climbing assisting device comprises a freight back frame (1), wherein assisting moving frames (2) are symmetrically arranged on the left side and the right side of the freight back frame (1); each of the assisting moving frames (2) comprises two wheel discs (3) which are arranged from top to bottom; wheel disc fixing plates (4) are separately arranged in the positions corresponding to the wheel discs (3), on the side surface of the freight back frame (1);a crank shaft (5) is arranged in the center of the inner side surface of each of the wheel discs (3), and comprises an inverted U-shaped connecting rod (6) connected with the corresponding wheel disc (3); and one edge of the opening end of each of the inverted U-shaped connecting rods (6) is connected with the center of the corresponding wheel disc (3). The stair climbing assisting device for freight transportation provided by the invention adopts a walking type, and is simple in structure, easy to control, stable in stair climbing and lifting, and high in adaptability to terrains, and the pace of the stair climbing assisting device and the pace of people are synchronous, so that the labor strength of freight transportation staff for transporting freights upstairs can be greatly reduced.
Description
technical field [0001] The invention relates to an auxiliary device for climbing stairs for freight, which belongs to the technical field of auxiliary mechanical devices for freight. Background technique [0002] At present, the existing auxiliary devices for climbing stairs mainly include crawler type, wheel set type and walking type etc. Among them, the crawler type has a large weight and is not flexible enough to operate, and the pressure on the edge of the stairs is relatively large when climbing stairs; the wheel group type has a wide range of motion and flexible movement, but the stability is not high when going up and down the stairs, and the center of gravity fluctuates greatly, which will make the user feel uncomfortable. Feeling uncomfortable; the walking style has high requirements on the control system, complex operation, small range of motion, and slow movement. Especially some automatic stair-climbing auxiliary devices currently on the market have complicated ...
