The invention discloses a transport trolley applied to a muddy road of a construction site. A vehicle body is included. Four lifting mechanisms are symmetrically distributed below the vehicle body; each lifting mechanism comprises a wheel supporting block fixedly arranged on a lower end surface of the vehicle body; a wheel frame is arranged below the wheel supporting block; a rotating cavity withan upward opening is arranged in an upper end of the wheel frame; and a rotating sliding block is rotatably arranged in the rotating cavity. In the invention, wheel sinking can be automatically detected when the trolley passes through a muddy road; then the auxiliary lifting mechanism is controlled to be unfolded to increase a contact area between the wheels and the ground; a lifting force is increased through the method of increasing the contact area; in addition, the lifting mechanism can automatically determine an unfolding size according to a sinking degree of the wheels, and action efficiency is improved; and meanwhile, the auxiliary pushing mechanism can apply a forward assisting force to the trolley to help the trolley move on a muddy and wet slide way.

    本发明公开了一种应用于建筑工地泥泞道路的运输小车,包括车体,所述车体下方对称分布有四个抬升机构,所述抬升机构包括固定设置在所述车体下端面上的车轮支持块,所述车轮支持块下方设置有车轮架,所述车轮架上端设有开口朝上的转动腔,所述转动腔内转动设有转动滑块,本发明可在推车通过泥泞道路时自动检测到车轮下陷,随后通过控制辅助抬升机构展开来增大车轮与地面的接触面积,通过增大接触面积的方法来增大抬升力,此外抬升机构可自动根据车轮的下陷程度来确定展开大小,提高行动效率,同时,辅助推动机构可对小车施加一个向前的助力,帮助小车在泥泞湿滑道路上行动。
