The invention relates to the field of telescopic arms, and discloses a telescopic arm, a pin inserting and pulling mechanism of the telescopic arm, an operation method of the pin inserting and pulling mechanism and engineering machine.The pin inserting and pulling mechanism comprises a body part, a telescopic oil cylinder, a connecting piece, a bent arm, a cylinder pin and a mechanical lock, and the telescopic oil cylinder can drive the connecting piece and the mechanical lock to move between a low position and a high position in the second direction; in the low position, the connecting piece drives the arm pin to move to the first unlocking position in the third direction through the bent arm, the mechanical lock limits the cylinder pin to move from the second locking position to the second unlocking position in the third direction, and in the high position, the connecting piece drives the arm pin to move to the first locking position in the third direction through the bent arm. The mechanical lock allows the cylinder pin to move in a third direction from the second locked position to the second unlocked position. According to the technical scheme, the telescopic oil cylinder, the bent arm and the mechanical lock are matched with one another, locking and unlocking of the arm pin and the cylinder pin can be achieved, the structure is simplified, the operation efficiency is improved, and the service life is prolonged.
本发明涉及伸缩臂领域,公开了一种伸缩臂及其插拔销机构和操作方法以及工程机械,插拔销机构包括本体部、伸缩油缸、连接件、弯曲臂、缸销和机械锁,伸缩油缸能够驱动连接件和机械锁沿第二方向在较低位置和较高位置之间移动,在较低位置,连接件通过弯曲臂带动臂销沿第三方向移动到第一解锁位置,机械锁限制缸销沿第三方向从第二锁定位置向第二解锁位置移动,在较高位置,连接件通过弯曲臂带动臂销沿第三方向移动到第一锁定位置,机械锁允许缸销沿第三方向从第二锁定位置向第二解锁位置移动。通过上述技术方案,伸缩油缸、弯曲臂和机械锁相互配合,可以实现对臂销和缸销的锁定和解锁,简化了结构,提高了操作效率,且延长了使用寿命。
