The invention discloses a working method of an anti-falling mechanism of a stacker lifting platform. The problem that the weight of a stacker is greatly increased in an existing mechanism is solved. 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的工作方法,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。
