Electric power assisted carrying device for stair

Abstract

The invention relates to an electric power assisted carrying device for a stair. The electric power assisted carrying device comprises a rack, wherein the two ends of the lower end surface of the rackare rotatably connected with axles; the two ends of each axle are coaxially rotatably provided with triangular wheel assemblies; a drive device for driving the axles to rotate is mounted on the rack;the front end of the rack is fixed with a holding handle; a controller for controlling rotation speed of the drive device is mounted on the holding handle; the two sides and the rear end of the rackare rotatably hinged with side baffle plates and a rear baffle plate separately; and a traction device for controlling rotation angles of the side baffle plates and a rotation angle of the rear baffleplate is mounted on the rack. In this way, the traction device, the side baffle plates and the rear baffle plate are matched, so that a user conveniently loads and unloads goods from multiple directions of the rack; when the side baffle plates and the rear baffle plate abut against ground, goods can be loaded and unloaded from an inclined surface formed by the side baffle plates and the rear baffle plate, so that a function of conveniently loading and unloading heavy things is realized; and the drive device drives the triangular wheel assemblies to rotate, so that the function of reducing manual labor while heavy things are carried on the stair is realized.

Description

technical field [0001] The invention relates to the technical field of conveying devices, in particular to an electric auxiliary conveying device for stairs. Background technique [0002] At present, in many occasions, it is necessary to carry heavy objects for translation or up and down the stairs. In buildings without elevators, it is still carried by manpower. Larger items or items with irregular structures are difficult to carry up the stairs manually. [0003] Some existing trolleys are equipped with triangular wheels, which can realize the movement of loaded goods up and down the stairs. However, this type of trolley still needs manpower to push and pull when carrying goods. force. On the one hand, the human labor is still relatively large, and it is prone to danger. On the other hand, the goods are easy to slide off the trolley under the action of their own gravity, resulting in loss of personnel and property, and there is room for improvement.
