The bidirectional telescopic device comprises a fixing plate fixedly installed on a crown block body, a first sliding assembly, a second sliding assembly and a third sliding assembly are sequentially installed at the bottom of the fixing plate from top to bottom in a sliding mode, and a driving assembly for driving the first sliding assembly to linearly slide is fixedly installed on the first sliding assembly; a rotating assembly for adjusting the grabbing angle is installed at the bottom of the third sliding assembly. By the adoption of the technical scheme, the extension distance of the crown block gripper is increased, the gripping angle can be adjusted, the coverage range of gripped materials is greatly enlarged, the occupied space is small when the crown block gripper retracts after gripping is completed, the overall structure is simple, and stability is good.
本发明涉及一种双向伸缩装置,包括固定安装在天车主体上的固定板,固定板底部由上至下依次滑动安装有第一滑动组件、第二滑动组件及第三滑动组件,第一滑动组件上固定安装有驱动第一滑动组件线性滑动的驱动组件,第三滑动组件的底部安装有调整抓取角度的旋转组件。采用本发明技术方案,使得天车抓手伸出距离变长,并且能够调节抓取角度,大幅提高了抓取物料的覆盖范围,抓取完毕缩回时占用空间小,整体结构简单,稳定性好。
