The invention discloses an anti-falling mechanism of a stacker lifting platform. The anti-falling mechanism solves the problem that the weight of a stacker is greatly increased in an existing mechanism. When the lifting platform falls suddenly, an annular steel wire rope (37) connected with the lifting platform rotates in an accelerated mode, a speed limiting brake (36) is triggered to brake, a right swing arm (9) is made to swing upwards around a right pin shaft (8), and a right movable wedge block (15) is driven to move upwards to be wedged in a gap between a right fixed wedge block (16) and the vertical face of the front side of a right stand column (3). A right front L-shaped adapter frame (17) is pulled forwards through a right movable wedge block and a right fixed wedge block (16) in sequence by counter-acting force generated after a right stand column (3) is wedged into a right movable wedge block (15), and the right front L-shaped adapter frame clamps a right rear clamping block (20) on the rear side vertical face of the right stand column (3) through a pair of parallel pull rods (18) and a right rear L-shaped adapter frame (19), so that the lifting table is prevented from falling.

    本发明公开了一种堆垛机升降台的防坠落机构,解决了现有机构存在的大幅增加堆垛机重量的问题;当升降台突然坠落时,与升降台连接的环形钢丝绳(37)加速旋转,触发限速制动器(36)制动,导致右摆臂(9)围绕着右销轴(8)向上摆动,带动右活动楔形块(15)向上移动,楔紧在右固定楔形块(16)与右立柱(3)的前侧立面之间的空隙中;右立柱(3)对右活动楔形块(15)楔入后所产生的反作用力,依次通过右活动楔形块和右固定楔形块(16)将右前L形转接架(17)向前拉拽,右前L形转接架通过一对平行拉杆(18)和右后L形转接架(19),将右后抱夹块(20)夹持在右立柱(3)的后侧立面上,阻止升降台的坠落。
