The capital construction material carrying trolley comprises a crawler rack and a connecting rod, large driven wheels which are symmetrically distributed are movably installed on the inner side surface of the crawler rack, a small driven wheel is installed at the position, above the large driven wheels, of one end of the crawler rack, and a small wheel shaft is movably hinged to one end of the connecting rod; and a small pull rod is mounted at the other end of the connecting rod. A series of structures are arranged, when goods are carried on a flat road, small wheels are lower than the lower surface of a crawler belt, the carrying cart is in a roller mode, and when the road condition is poor or the carrying cart goes up and down stairs, a lifting gear motor drives a lifting transmission shaft to rotate, then a small pull rod and a connecting rod are driven to move, and then small wheel shafts are driven to rotate; meanwhile, the transition shaft and the fisheye push rod can be driven to move through pulling of the long pull rod, the large wheel is pushed to rotationally ascend around the crawler rack, the large wheel slowly ascends to be higher than the crawler, and at the moment, the carrier loader is switched into a crawler mode.
本发明公开了一种适应性强的基建物资运载小车,包括履带机架和连杆,所述履带机架内侧表面活动安装有呈对称分布的大从动轮,所述大从动轮上方的履带机架一端安装有小从动轮,所述连杆的一端活动铰接有小轮轴,所述连杆的另一端安装有小拉杆。本发明通过设置有一系列的结构,通过当在平路运载货物时,此时小轮低于履带的下表面,运载车为滚轮模式,当路况不好或者上下楼梯时,此时升降减速电机带动升降传动轴转动,进而带动小拉杆、连杆运动,再带动小轮轴转动,此时小轮慢慢上升至高于履带,同时通过长拉杆的拉动会带动过渡轴和鱼眼推杆运动,推动大轮绕履带履带机架旋转上升,大轮慢慢上升至高于履带,此时运载车切换为履带模式。
