The invention belongs to the technical field of material carrying devices, and particularly relates to a hydraulic external locking type locking pull arm device which comprises an outer fixing frame, a first connecting rod, a second connecting rod, a first locking rod and a second locking rod. The second connecting rod is arranged on the rear side of the first connecting rod, and the second connecting rod is fixedly connected with the outer fixing frame; the second connecting shaft penetrates through and is rotationally connected with the outer fixing frame; the connecting arm penetrates through and is rotationally connected with the second connecting shaft; and the front side of the bottom of the connecting arm penetrates through and is rotationally connected with a third connecting shaft. According to the hydraulic external locking type locking pull arm device, through mutual cooperation of a third limiting hook, a limiting spring, an arc-shaped open hole, a swing column, a limiting plate, a third connecting shaft and an arc-shaped locking plate, two different operation modes can be achieved on the premise that the driving mode is not changed, the requirements for unloading and container carrying are met at the same time, and the practicability is high. The device is convenient to operate, and the application range of the device is widened.

    本发明属于物料搬运装置技术领域,具体的说是一种液压外锁式锁定拉臂装置,包括外固定架:固定连接在外固定架上的第一连接杆;设置在第一连接杆后侧的第二连接杆,且第二连接杆与外固定架固定连接;贯穿并与外固定架转动连接的第二连接轴;贯穿并与第二连接轴转动连接的连接臂;所述连接臂底部前侧贯穿并转动连接有第三连接轴。本发明所述的一种液压外锁式锁定拉臂装置,通过第三限位挂钩、限位弹簧、弧形开孔、摆动柱、限位板、第三连接轴和弧形锁定板之间的相互配合,可以在不改变驱动方式的前提下,实现两种不同的运转方式,同时满足了卸料和货箱搬运的情况,装置操作便捷,提高了装置的适用范围。
