The invention discloses a lifting vehicle body, wheels and a crawler belt combined type stair climbing vehicle, which belongs to one of stair climbing vehicles. Due to the fact that an existing stairclimbing vehicle is small in load capacity, large in physical output of operators, not high in safety and the like. According to the technical scheme, a chassis is composed of a full-load, high-trafficability and low-abrasion crawler-type traveling device and used for traveling on stairs; a lifting system is arranged at the proper position of the vehicle body and used for lifting the vehicle bodyto achieve switching of wheels and crawler belts and assist the crawler belts to climb stairs. Trundles are mounted at the bottom end of the lifting system and used for driving on a road surface or astair platform; a goods shelf can move horizontally, the gravity center of goods is moved forwards, and the safety of the vehicle running on stairs is improved; double independent retractable safety tails are arranged at the tail of the vehicle body, so that the safety of the vehicle is further improved, and the vehicle is prevented from overturning. According to the invention, safe transportationof large-load-capacity and large-volume goods on stairs can be realized.
升降车体,车轮、履带复合式爬楼车,属于爬楼车的一种。由于现有爬楼车存在载重量小、操作人员体力消耗大、安全性不高等这些问题。本发明的技术解决方案是:由全负载式、高通过性、低磨损履带式行走装置组成的底盘,用来在楼梯上行驶;在车体的适当位置设置升降系统,用来升降车体实现车轮、履带的切换和辅助履带攀爬楼梯;在升降系统的底端安装脚轮,用来在路面或者楼梯平台上行驶;货架可水平移动,将货物的重心前移,提高车辆在楼梯上行驶的安全性;车体尾部设置有双独立可收放式安全尾,进一步提高车辆的安全性,防止车辆翻覆。本发明可以实现大载重量、大体积货物在楼梯上的安全运输。
