The invention provides a crane telescopic boom bolt device driven by a hydraulic cylinder and a working method thereof, the device comprises a telescopic hydraulic cylinder, a sliding mechanism and a bolt mechanism, a crane telescopic boom comprises a basic boom and a plurality of sections of telescopic booms, and the root of each section of telescopic boom is provided with a boom pin; the telescopic hydraulic cylinder comprises a piston rod and a cylinder barrel, the piston rod is connected with the root of the basic arm, the sliding mechanism is installed on the cylinder barrel, and the bolt mechanism is connected to the sliding mechanism; reciprocating movement of the cylinder barrel relative to the piston rod is achieved through the telescopic hydraulic cylinder, the sliding mechanism is driven to act through movement of the cylinder barrel, the sliding mechanism is used for driving the plug pin mechanism to slide to each section of telescopic arm along the cylinder barrel, and the plug pin mechanism is used for achieving locking connection of the cylinder barrel and the telescopic arm. And the telescopic arm is driven by the cylinder barrel to extend or retract. The invention has the characteristics of increasing the effective displacement of the cylinder pin and the pin plugging and unplugging device, reducing the stroke of the telescopic hydraulic cylinder, reducing the total weight of the boom system, reducing the manufacturing cost and having wide application range.

    本发明提供一种液压缸驱动的起重机伸缩臂插销装置及其工作方法,装置包括伸缩液压缸、滑动机构和插销机构,起重机伸缩臂包括基本臂和多节伸缩臂,每节伸缩臂根部设有臂销;伸缩液压缸包括活塞杆和缸筒,活塞杆与基本臂的根部连接,滑动机构安装在缸筒上,插销机构连接在滑动机构上;通过伸缩液压缸实现缸筒相对活塞杆进行往复移动,通过缸筒的移动带动滑动机构动作,滑动机构用于驱动插销机构沿缸筒滑动至每节伸缩臂处,插销机构用于实现缸筒和伸缩臂进行锁定连接,锁定连接后,通过缸筒带动伸缩臂进行伸出或缩回。本发明具有增加缸销与插拔销装置的有效位移,减小伸缩液压缸的行程,减小臂架系统的总体重量,降低制造成本,应用范围广的特点。
