The invention discloses an adjustable crane trolley limiting device with a buffering structure. The adjustable crane trolley limiting device comprises a supporting pillar, a movable track and a suspension mechanism, wherein the movable track is horizontally fixed to the top end of the supporting pillar, the longitudinal section of the movable track is of an I-shaped structure, the tail end and thehead end of the movable track are provided with two opposite limiting assemblies respectively, the limiting assemblies correspond to movable trolleys, a supporting strip and an auxiliary limiting strip are fixed to the outer side face of each movable trolley separately, and a stabilizing assembly is fixed to the surface of the bottom of each supporting strip. According to the adjustable crane trolley limiting device, the limiting assemblies with the buffering characteristics are installed at the head end and the tail end of the movable track respectively, can limit movement of the trolleys, and gradually decelerate the trolleys until the trolleys stop so as to guarantee higher safety in use of the trolleys. Through the arrangement of adjusting assemblies, the positions of the limiting assemblies can be properly adjusted, so that the extreme position of the trolleys is controlled. Through the arrangement of the stabilizing assemblies, the trolleys are enabled to move more safely and stably.

    本发明公开了一种可调式的带有缓冲结构的起重机小车限位装置,包括支撑柱、活动轨道和悬吊机构,活动轨道水平固定于支撑柱的顶端,活动轨道的纵向切面为“工”字型结构;活动轨道的尾端与首端分别安装有两个相对设置的限位组件,限位组件与活动小车相对应;活动小车的外侧面分别固定有托条和辅助限位条,托条的底部表面固定有稳定组件;本发明在活动轨道的首端与尾端分别安装了具有缓冲特性的限位组件,限位组件能够限制小车的活动,并使小车的速度逐渐降低直至停车,使用更加安全;本发明通过调节组件的设置,能够适当调节限位组件的位置,即控制小车的极限位置;本发明稳定组件的设置,能够使得小车的活动更加安全稳定。
