The invention discloses a hoisting machine for highway bridge construction. The hoisting machine comprises a base, a guide seat, a lifting oil cylinder, a lifting seat, a motor I, a parallel hoisting mechanism, a grabbing mechanism and the like, a second motor in the grabbing mechanism is started, the second motor can drive a vertical screw to rotate, rotation of the vertical screw enables a telescopic base to move downwards as a whole, and therefore a fourth motor can drive two clamping blocks to move towards the inner side to clamp a heavy object, and great convenience is brought to heavy object transferring; according to the parallel hoisting mechanism, through the two sets of linked parallel four-bar mechanisms, it can be guaranteed that a heavy object is in a horizontal state all the time in the transferring process, and therefore it is guaranteed that the heavy object does not shake in the transferring process, and the heavy object installation efficiency is improved; a third motor arranged in the grabbing mechanism can drive a guide groove seat to rotate integrally through a driving gear, a driven gear and a rotating seat, so that the heavy object can be rotated to a required angle, and great convenience is brought to heavy object installation.

    本发明公开了一种公路桥梁施工用吊装机,包括底座、导向座、升降油缸、升降座、电机一、平行吊装机构和抓取机构等;本发明中启动抓取机构中的电机二,而电机二则能够带动竖向螺杆旋转,而竖向螺杆的旋转则使伸缩座整体下移,从而能够通过电机四驱使两个夹持块向内侧移动夹住重物,也就给重物转运带来了很大的便利性;本发明平行吊装机构中通过两组联动的平行四连杆机构,能够确保重物转运中始终处于水平的状态,从而确保了重物转运时不会产生晃动的现象,也就提高了重物安装的效率;本发明抓取机构中设置的电机三,能够通过主动齿轮、从动齿轮和旋转座带动导槽座整体旋转,从而能够将重物旋转成需要的角度,也就给重物安装带来了很大的便利性。
