Load-carrying stair-climbing conveyor

Abstract

The invention discloses a load-carrying stair-climbing conveyor. The load-carrying stair-climbing conveyor comprises a rack, walking wheels and a stair climbing actuator arranged on the rack. The stair climbing actuator comprises a driving device and an oscillating rod. The oscillating rod is driven by the driving device to rotate and drives the rack and the walking wheels to move upwards with a ground touch point formed when the oscillating rod rotates to be in contact with a stair step surface as a supporting point. The conveyor is suitable for moving on the flat ground and climbing stairs. Due to the fact that the driving device drives the oscillating rod to rotate and keeps working when the oscillating rod rotates to be in contact with the stair step surface, the oscillating rod can oscillate around the touch point, namely the supporting point, and then the rack is driven to move upwards. In other words, when the oscillating rod moves till the walking wheels touch the ground, the whole conveyor goes up one step, and the process of going upstairs is realized. The overall structure is simple and compact, the stair climbing-up process is easy to realize, the structural stability is high, movement is flexible, switchover between a flat ground traveling mode and a stair climbing mode is easy to realize, and manufacturing cost is low; meanwhile, the stability and safety are high in the overall running process, so that stair-climbing carrying efficiency is greatly improved, and labor cost is reduced.

Description

technical field [0001] The invention relates to the field of ladder climbing devices, in particular to a load-climbing stair-climbing conveyor. Background technique [0002] In people's daily life and production activities, they often encounter the problem of transporting heavy objects to high places through stairs. The traditional method is manual handling, but this is inefficient, dangerous, and time-consuming. . [0003] In order to change this situation, many studies have designed stair climbing machines that can climb stairs. According to the type of work, there are mainly two types: continuous type and intermittent type. Among them, the continuous type of stair climbing machine is widely used. There is only one set of supporting devices in the process of climbing stairs, relying on the continuous movement of the supporting devices to realize the function of the car body or wheelchair going up and down stairs. The continuous stair climbing machine can be divided into ...

Problems solved by technology

The stair-climbing process of this mechanism is similar to the process of people going up and down the stairs, and some people call it a walking stair climbing car, but due to the movement of the legs, they cannot move smoothly on a flat surface. The walking stair climbing car is currently under domestic research. Less, most of the products on the market are foreign products, expensive
