The invention relates to a trolley capable of preventing slope sliding and tipping. The device comprises a chassis, a supporting frame and a hopper, front wheels and rear wheels are arranged at the bottom of the chassis, and a handle is arranged at the rear end of the chassis; the supporting frame is arranged on the upper surface of the chassis, rotatable arc tooth rings are arranged on the left side wall and the right side wall of the supporting frame, and teeth are distributed on the outer side faces of the arc tooth rings; gears are arranged on the two side faces of the hopper, the hopper is located in the supporting frame, the gears are meshed with the arc gear ring, the lower end of the arc gear ring is connected with the limiting rod through a first spring and a second spring and acts on the brake rod, and a brake pad on the brake rod can be matched with resistance devices on the front axle and the rear axle when the brake rod moves downwards. When the trolley goes uphill and downhill, the hopper rotates, the gear rolls along the arc gear ring, the gravity center of the hopper can be moved to the high position while materials are kept horizontal, tipping is prevented, meanwhile, the arc gear ring rotates to press the brake rod downwards, the brake pad and the resistance device are matched to prevent the trolley from slipping when the trolley goes uphill, and safety is high.

    本发明涉及一种防溜坡防倾翻的手推车。其包括底盘、支撑架和料斗,底盘的底部设置有前车轮和后车轮、后端设置有把手;支撑架设置于底盘上表面,支撑架的左右两侧壁设置有可转动的弧齿圈,弧齿圈的外侧面分布有齿牙;料斗的两侧面设置齿轮,料斗位于支撑架内且齿轮和弧齿圈啮合,弧齿圈下端通过第一弹簧和第二弹簧连接限位杆且作用于刹车杆,刹车杆上的刹车片在刹车杆下移时能够与前轮轴和后轮轴上的阻力装置配合。本发明在手推车上坡和下坡时,料斗转动,齿轮沿弧齿圈滚动,保持物料水平的同时能够将料斗重心向高处挪动,防止倾翻,同时弧齿圈转动下压刹车杆,在手推车上坡时刹车片与阻力装置配合阻止手推车溜坡,安全性高。
