Crawler-type loading chassis, horizontal stair climbing machine and self-adaptive climbing method

Abstract

The invention discloses a crawler-type loading chassis, a horizontal stair climbing machine and a self-adaptive climbing method; the crawler-type loading chassis comprises an objective table, the two sides of the objective table are hinged to a front crawler belt assembly and a rear crawler belt assembly through a front rotating rod and a rear rotating rod respectively, the front crawler belt assembly comprises a front crawler belt section and a rear crawler belt section, and a first included angle is formed between the rear crawler belt section and the front crawler belt section; a rotating shaft is arranged at the rear end of the front track assembly or close to the rear end, and meanwhile, the rotating shaft is arranged at the front end of the rear track assembly or close to the front section; the front crawler belt assembly and / or the rear crawler belt assembly are / is hinged to the objective table through a telescopic mechanism. And a locking mechanism is used for locking the telescopic mechanism. The stair climbing machine can bear large load capacity, the objective table is always parallel to the ground in the stair climbing process, the gravity center of the objective table is pressed at the upper end of the objective table in the stair climbing process, and controllability, safety and working efficiency are higher.

Description

technical field [0001] The invention relates to the technical field of stair climbing machines, in particular to a crawler-type load-carrying chassis, a horizontal stair climbing machine and an adaptive climbing method. Background technique [0002] With the development of buildings, more and more high-rise buildings are gradually rising, and some large items or goods cannot be transported by elevators. At the same time, some old communities do not have elevators, so they can only be transported through the stairs by the load climbing machine. for transport. [0003] At present, there are three main structures of the load stair climbers on the market, one is the dial rocker type, the other is the three-star wheel type, and the third is the rear-mounted crawler chassis type. The common disadvantage of the stair climbing machines of these three structures is that the center of gravity of the entire stair climbing machine is pressed on the lower end of the chassis during the p...

AI Technical Summary

Problems solved by technology

The common disadvantage of the stair climbing machines of these three structures is that the center of gravity of the entire stair climbing machine is pressed on the lower end of the chassis during the process of going up and down the stairs. The operator needs to press the operating handrail hard, otherwise the whole car body will tilt forward. , causing the danger of overturning, resulting in not being able to have too much load, and the handling, safety and work efficiency are also very low; and the existing stair climbing machine is in the process of climbing the stairs. Under the action of the chassis, the middle position of the chassis is in contact with the uppermost step of the stairs, causing the chassis to rotate, and the front section of the chassis is directly in contact with the ground without cushioning, which is easy to cause damage to the goods, and the front section of the chassis rotates too fast, which affects the service life of the chassis. , low safety factor
