The invention relates to the technical field of building construction, and discloses a trolley for a construction site. A hydraulic transmission hole communicating with the interior of a corrugated pipe is formed in a handle, a transmission wheel is movably installed in a transmission cavity, a ratchet wheel is arranged on the outer ring of one side of a rotating shaft, and the end, stretching into the top of the ratchet wheel, of a second hydraulic hole channel is movably sleeved with a clamping block; a hydraulic annular groove with the back face communicating with the hydraulic cavity is formed in the middle circle in the transmission wheel, a tooth key is movably sleeved with a notch, a transmission shaft is movably installed in the bottom wall of the frame, a conductive rod matched with the magnetic block is fixedly installed in a rotating shaft, and a resistance groove is formed in the bottom of a connecting sleeve and sleeved with a light ball rod. The hydraulic ring cavity is internally and movably sleeved with the top ring, hydraulic pressure change in the vehicle body is controlled through the handle, the electromagnetically matched top ring is arranged in the wheel, it can be effectively guaranteed that the vehicle body can be more convenient to use, and the protection effect is achieved when the vehicle body slips out of the hand.

    本发明涉及建筑施工技术领域,且公开了一种建筑工地用手推车,把手的内部开设有与波纹管内部连通的液压传递孔,传动腔内部活动安装有传动轮,转轴一侧的外圈设置有棘轮,第二液压孔道伸入到棘轮顶部处的端部活动套接有卡块,传动轮内部中圈开设有背面与液压腔连通的液压环槽且槽口内部活动套接有齿键,车架底壁的内部活动安装有传动轴,转轴的内部固定安装有配合磁块的导电杆,连接套的底部开设有电阻槽且套接有轻球杆,液压环腔内部活动套接有顶环,通过把手控制车体内部液压变化,并且在车轮内部设置电磁配合顶环,可以有效地保证了车体在使用时可以更加的方便,且在脱手时起到保护作用。
