The invention discloses a chain breaking protective mechanism for a stacker. The chain breaking protective mechanism comprises a bottom plate, wherein a stand column is mounted on the top of the bottom plate; a top plate is mounted on the top of the stand column; a motor is mounted on the outer surface of the stand column; the output end of the motor is equipped with a cylinder; a fixed pulley ismounted on the bottom of the top plate; a steel wire rope is mounted on the outer surface of the cylinder and the outer surface of the fixed pulley in a transmission mode; a slide block is mounted onthe outer surface of the stand column in a sliding mode; and a fixing device is mounted on the outer surface of the slide block. A limiting block arranged in the protective device can sleeve the outersurface of a steel wire rope to limit a transmission rod, and a spring can be expanded under a steel wire rope breaking condition to rotate the transmission rod, so that a limiting block pressing control device starts an external control device through a control device; a gas cylinder and a fixing block are arranged inside the fixing device, so that a clamping block can be driven to clamp and fixthe stand column, and thus, the steel wire rope of the stacker can be prevented from accident damages under a breaking condition.

    本发明公开了一种堆垛机断链保护机,包括底板,所述底板的顶部安装有立柱,所述立柱的顶部安装有顶板,所述立柱的外表面安装有电机,所述电机的输出端安装有圆筒,顶板的底部安装有定滑轮,圆筒和定滑轮的外表面传动安装有钢丝绳,所述立柱的外表面滑动安装有滑块,所述滑块的外表面安装有固定装置。本发明,防护装置内部设置有限位块套设在钢丝绳外表面能够限制传动杆,弹簧在遇到钢丝绳断绳的情况下能够展开使传动杆转动,使限位块按压控制装置通过控制装置启动外部控制装置,固定装置内部设置有气压缸和固定块,能够带动夹持块对立柱进行夹持固定,能够有效防止堆垛机钢丝绳在断落情况下出现事故损伤。
