The invention discloses a cart with a braking function. The cart comprises a cart hopper base, a cart hopper, handles, a wheel assisting mechanism and a downhill speed reducing mechanism, wherein thecart hopper base is of an L-shaped structure, the cart hopper is longitudinally connected to the part, which is parallel to the ground, of the cart hopper base in a sliding mode by virtue of a plurality of damping springs, the two handles are fixed to the part, which is perpendicular to the ground, of the cart hopper base, a shaft seat is perpendicularly fixed to the bottom end of the cart hopperbase, wheel shafts which are parallel to the ground are rotatably connected to the shaft seat, two wheels are fixed to each wheel shaft by virtue of one-way bearings, and the downhill speed reducing mechanism comprises speed reducing discs which are fixed to the side walls of the one-way bearings, speed reducing clamping teeth which are located on the inner rings of the speed reducing discs, telescopic sleeves which are annularly arranged on the surfaces of the wheel shafts, telescopic clamping rods which are connected to the interiors of the telescopic sleeves in the sliding mode and a hydraulic mechanism which is used for driving the telescopic clamping rods. According to the cart, operating personnel can conveniently control the speed of the cart in a downhill process or brake the cartin time in emergency through the downhill speed reducing mechanism, and potential safety hazards caused by high speed of the cart to the operating personnel are prevented.

    本发明公开了一种具有刹车功能的推车,包括车斗底座、车斗、把手、车轮助力机构和下坡减速机构,车斗底座为“L”型结构,车斗底座与地面平行的部位通过多个减震弹簧在纵向上滑动连接有车斗,车斗底座与地面垂直的部位固定有两个把手,车斗底座底端垂直固定有轴座,轴座转动连接有与地面平行的车轮轴,车轮轴均通过单向轴承固定有两个车轮,下坡减速机构包括固定在单向轴承侧壁上的减速盘、位于减速盘内圈上的减速卡齿、环设在车轮轴表面上的伸缩套筒,滑动连接于伸缩套筒内的伸缩卡杆和用于驱动伸缩卡杆的液压机构,本发明通过下坡减速机构便于工作人员控制车体在下坡的过程中的车速或紧急时刻进行及时刹车,防止车体过快而给工作人员带来安全隐患。
