The invention discloses a labor-saving building cart. The labor-saving building cart comprises a cart hopper base, a cart hopper, handles, a wheel assisting mechanism and a downhill speed reducing mechanism, wherein the cart 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 byvirtue 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 endof the car hopper base, wheel shafts which are parallel to the ground are rotatably connected to the shaft seat, and two wheels are fixed to each wheel shaft by virtue of one-way bearings; and the assisting mechanism comprises assisting gears which are fixed to the two one-way bearings and two rack plates which are fixed to the bottom end of a guide sliding block, perpendicularly penetrate through the cart hopper base, extend to the position below the cart hopper base and are matched with the two power assisting gears. According to the labor-saving building cart, when the cart is pushed to advance on the construction site with pavement irregularity, the cart can vibrate, and the vibration force generated by vibration is converted into power of the wheel power assisting mechanism so as toassist the cart to continuously advance, so that the labor-saving effect is achieved.
本发明公开了一种省力型建筑推车,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;助力机构包括固定在两个单向轴承上的助力齿轮和固定在导向滑块底端上并垂直穿过车斗底座延伸至车斗底座下方与两个助力齿轮相适配的两个齿条板,本发明在路面不平的施工场地上推动推车前进时,车体会产生震动,并利用震动产生的“震动力”转化成车轮助力机构的动力来辅助车体继续前进,起到省力的效果。
