The invention relates to the technical field of hoisting frames, in particular to a lifting hoisting frame for railway vehicle installation. The lifting hoisting frame comprises bases, supporting seats are welded on the outer walls of the tops of the bases, supporting columns are welded on the outer walls of the tops of the supporting seats, lifting columns are inserted into the top ends of the supporting columns, lifting motors are fixed on the inner walls of the bottoms of the supporting columns through bolts, the output ends of the lifting motors are rotationally connected with screw rods through couplers, and internal thread sleeves located inside the supporting columns are welded to the outer walls of the bottoms of the lifting columns. The lifting hoisting frame has the beneficial effects that the heights of the lifting columns can be adjusted through cooperation of the screw rods and the internal thread sleeves, the lifting columns can be suitable for different lifted objects, and compared with a pure hydraulic cylinder lifting mode, the lifting mode by which the screw rods and the internal thread sleeves are in threaded fit enables the lifting columns to be higher in lifting height and higher in stability; and when guide rods slides inside guide columns, the position deviation of the lifting columns during lifting can be prevented, so that the guide effect on the lifting columns is achieved.

    本发明涉及起吊架技术领域,具体是一种轨道车辆安装用升降起吊架,包括底座,底座顶部的外壁上焊接有支撑座,且支撑座顶部的外壁上焊接有支撑柱,支撑柱的顶端插接有升降柱,支撑柱底部的内壁上通过螺栓固定有升降电机,且升降电机的输出端通过联轴器转动连接有螺杆,升降柱底部的外壁上焊接有位于支撑柱内部的内螺纹套管。本发明的有益效果:螺杆与内螺纹套管配合能够对升降柱的高度进行调节,能够适用不同的吊起物,并且螺杆螺纹内螺纹套管升降的方式与纯液压缸升降的方式对比,能够使升降柱的上升高度更高,稳定性更强,导向杆在导向柱的内部滑动时,能够防止升降柱升降时位置偏移,从而对其具有导向的作用。
