The invention belongs to the field of hoisting equipment, and particularly discloses a lifting point variable trolley based on a low clearance structure. The trolley comprises a trolley frame, a trolley running mechanism, a hoisting mechanism, a rigid frame, a rigid frame running mechanism, a pulley beam and a pulley mechanism. The trolley running mechanism is mounted on the trolley frame. The hoisting mechanism is fixedly supported above the rigid frame, the pulley beam is fixedly connected below the rigid frame, the pulley mechanism is fixedly connected to the pulley beam, the rigid frame running mechanism is respectively matched with the rigid frame and the trolley frame, and the rigid frame is in sliding connection with the trolley frame through the rigid frame running mechanism. According to the trolley, on the premise that the height of the trolley is not changed, low-clearance two-way operation can be achieved, the positions of lifting points and the distance between the liftingpoints are changed, transformation of an old crane is facilitated, and the production efficiency is improved.

    本发明属于起重设备领域,具体公开一种基于低净空结构的吊点可变小车,该吊点可变小车包括小车架、小车运行机构、起升机构、刚性框架、刚性框架运行机构、滑轮梁和滑轮机构;所述小车运行机构安装于小车架上;所述起升机构固定支撑于刚性框架的上方,滑轮梁固定连接于刚性框架的下方,滑轮机构固定连接于滑轮梁上,刚性框架运行机构分别与刚性框架和小车架配合,刚性框架与小车架通过刚性框架运行机构滑动连接。本发明的吊点可变小车能够在不改变小车高度的前提下,实现低净空双向运行,改变吊点位置及吊点间距、有利于旧起重机的改造,提高生产效率。
