According to the cylinder arm pin driving mechanism, a first cylinder head body is arranged at the end, close to the tail of an arm frame, of a telescopic oil cylinder barrel, and a second cylinder head body is arranged at the end, away from the tail of the arm frame, of the telescopic oil cylinder barrel; a first cylinder head body dovetail groove and a first cylinder head body cylinder pin are arranged in the first cylinder head body; a second cylinder head body dovetail groove and a second cylinder head body cylinder pin are arranged in the second cylinder head body; the driving oil cylinder is a double-acting double-piston-rod oil cylinder, a first piston rod stretches out to drive a first cylinder head body cylinder pin and a second cylinder head body cylinder pin to move synchronously, and when the first piston rod retracts, the first cylinder head body cylinder pin and the second cylinder head body cylinder pin are reset through a reset spring. The second piston rod stretches out to drive the first cylinder head body dovetail groove and the second cylinder head body dovetail groove to move synchronously, and when the second piston rod retracts, the first cylinder head body dovetail groove and the second cylinder head body dovetail groove are reset through the reset spring.
本发明公开了一种缸臂销驱动机构,包括:所述伸缩油缸缸筒靠近臂架尾部的一端设有第一缸头体,所述伸缩油缸缸筒远离臂架尾部的一端设有第二缸头体;所述第一缸头体内设有第一缸头体燕尾槽和第一缸头体缸销;所述第二缸头体内设有第二缸头体燕尾槽和第二缸头体缸销;所述驱动油缸为双作用双活塞杆油缸,所述活塞杆一伸出带动第一缸头体缸销和第二缸头体缸销同步运动,当所述活塞杆一缩回时,所述第一缸头体缸销和第二缸头体缸销通过复位弹簧复位;所述活塞杆二伸出带动第一缸头体燕尾槽和第二缸头体燕尾槽同步运动,当所述活塞杆二缩回时,所述第一缸头体燕尾槽和第二缸头体燕尾槽通过复位弹簧复位。
