The anti-falling device comprises stand columns, and the stand columns are provided with fixing teeth. The cargo carrying table comprises a side body part and a bearing part; the bearing part is provided with a mounting bottom plate; the lifting pull rod is connected with the steel wire rope and the push rod; one end of the U-shaped connecting rod is provided with a chute; a sliding pin is arranged at the lower end of the push rod and arranged in the sliding groove. The connecting shaft is connected to the U-shaped connecting rod. The two ends of the rocker are hinged to the connecting shaft and the movable tooth fixing block respectively. The lifting pull rod is sleeved with a safety spring, and the safety spring is compressed between a connector on the lower portion of the lifting pull rod and the top inner wall of the side body portion. The locking assembly is provided with a locking space; when the steel wire rope is broken, the safety spring is changed into an extending state from a compressed state, the push rod is pushed to descend, the push rod drives the U-shaped connecting rod to rotate downwards, the U-shaped connecting rod drives the connecting shaft and the rocker, then the movable teeth are pushed to be meshed with the fixed teeth, the U-shaped connecting rod enters the locking space downwards and is locked in the locking space, and falling prevention of the cargo carrying table is reliably achieved.
本发明涉及双立柱堆垛机防坠落装置,包括立柱,立柱安装有固定牙;载货台包括侧体部和承载部;承载部具有安装底板;升降拉杆的两端具有连接头,升降拉杆连接钢丝绳与推杆;U型连杆一端具有滑槽;推杆的下端具有滑动销,滑动销设置于滑槽中;连接轴连接至U型连杆,摇杆的两端分别与连接轴以及活动牙固定块铰接;升降拉杆套有安全弹簧,安全弹簧压缩在升降拉杆下部的连接头与侧体部的顶内壁之间;锁紧组件具有锁定空间;当钢丝绳断裂时,安全弹簧从压缩状态变为伸展状态,推动推杆下降,推杆带动U型连杆向下转动,U型连杆带动连接轴、摇杆,进而推动活动牙与固定牙啮合,U型连杆向下进入锁定空间,被锁定在锁定空间中,可靠实现载货台防坠落。
