The arm pin inserting and pulling mechanism of the suspension arm comprises a main base, an arm pin inserting and pulling assembly, a cylinder pin assembly and a self-locking mechanism, the arm pin inserting and pulling assembly, the cylinder pin assembly and the self-locking mechanism are mounted on the main base, and a first mounting hole, a second mounting hole and a third mounting hole are formed in the main base at intervals; the arm pin inserting and pulling assembly comprises an arm pin oil cylinder, an arm pin cylinder rod body and an arm pin, the cylinder pin assembly is inserted into the second mounting hole, the self-locking mechanism is arranged in the third mounting hole, and when the cylinder pin assembly moves, the other end of the self-locking mechanism can extend into the first mounting hole under the pushing of the cylinder pin assembly so as to stop the arm pin cylinder rod body from moving. The invention further provides a hydraulic control system. According to the direct type arm pin inserting and pulling mechanism and the hydraulic control system thereof, when inserting and pulling of the arm pin inserting and pulling assembly are achieved, control through an additional mechanism is not needed, the self-locking mechanism is driven to move under movement of the cylinder pin assembly so as to move upwards to directly block the arm pin cylinder rod body, retraction of the arm pin cylinder rod body is avoided, and the interlocking function is achieved.

    本发明公开了一种吊臂的臂销插拔机构,该吊臂的臂销插拔机构包括主座以及安装于主座的臂销插拔组件、缸销组件以及自锁机构,主座间隔地开设有第一安装孔、第二安装孔以及第三安装孔,臂销插拔组件包括臂销油缸、臂销缸杆体、以及臂销,缸销组件插入第二安装孔,自锁机构设于第三安装孔内,缸销组件运动时,自锁机构的另一端在缸销组件的推动下可伸入第一安装孔内以止挡臂销缸杆体运动。本发明还提供一种液压控制系统。本发明公开的直接式臂销插拔机构及其液压控制系统在臂销插拔组件实现插拔时,无需通过另外的机构进行控制,在缸销组件的运动下带动自锁机构运动从而向上运行直接挡在臂销缸杆体处,避免臂销缸杆体回缩,实现互锁的功能。
