The invention relates to a crawler-type stair-climbing carrying trolley which comprises a crawler chassis, a mounting table is arranged above the crawler chassis, a middle jacking mechanism is arranged below the mounting table, the middle jacking mechanism comprises a roller assembly, and the roller assembly of the middle jacking mechanism can move in the direction perpendicular to a crawler belton the side, adjacent to the ground, of the crawler chassis. When the roller assembly is pushed downwards and makes contact with the ground, the reacting force makes the front end of the whole trolleyjacked up and the rear end of the crawler belt touch the ground, an inclined state that the front end of the whole trolley tilts up is formed, the crawler belt drives the whole trolley to move forwards, and the front part of the crawler belt crosses the stair steps and the roller assembly is driven to retract upwards, the front part of the crawler belt descends to be lapped on the edge of a second step, and the stepping and occupying process of the crawler conveying device is finished. According to the stair-climbing carrying troller, starting and occupying are completed with the help of themiddle jacking mechanism, and the danger that the whole gravity center of the stair climbing device is high and a vehicle turns over due to the fact that the gravity center is too high during stair climbing due to the fact that the height between the center of a driving wheel or the center of an inducer and the ground is increased is avoided.
本发明涉及一种履带式爬楼梯运载小车,包括履带底盘,履带底盘的上方设有安装台,安装台的下方设有中顶机构,中顶机构包括滚轮组件,中顶机构的滚轮组件可沿垂直于履带底盘相邻地面一侧履带的方向移动,滚轮组件被向下推出时,直至接地后,反作用力将整车前端顶起,而履带的后端着地,形成整车前端翘起的倾斜状态,履带驱动整车前行,履带前部越过楼梯踏步,滚轮组件被驱动往上回缩时,履带前部下降搭在第二步踏步边缘上,完成了履带运载装置上坡爬楼梯的起步进占过程,本发明借助中顶机构完成起步进占,避免通过增加驱动轮或诱导轮中心距地高度的方式带来的爬楼装置整体重心较高,在爬楼时因重心过高而翻车的危险。
