According to the lifting platform anti-falling mechanism and the method thereof, a new scheme that the relative positions of the traction piece and the anti-falling mechanism are flexibly designed is provided, so that the installation space can be effectively reduced, the traction force direction can be conveniently changed, and the brake triggering time is shortened. The lifting table anti-falling mechanism comprises a set of horizontally-arranged anti-falling guide column bases installed on the side arm of the cargo carrying table through bolts, the two vertical ends of a set of guide columns are installed between the anti-falling guide column bases in parallel, sliding blocks are arranged between the guide columns on the two sides in a sleeved mode respectively, compression springs are arranged between the anti-falling guide column base at the top end and the sliding blocks and on the guide columns in a sleeved mode, and the compression springs are connected with the anti-falling guide column bases through bolts. A chain tensioning seat and a cam shifting fork are mounted on the sliding block; a group of arc-shaped holes are formed in the cargo carrying table side arm, a group of cam shafts are installed on the cargo carrying table side arm, a traction piece is connected to the side portion of the cargo carrying table side arm, and a spring is arranged between the traction piece and the lifting plate and outside the sleeve in a sleeving mode; anti-falling angle steel is vertically installed on the cargo carrying table side arm, and a pair of brake cams are oppositely arranged between the anti-falling angle steel.
本发明所述升降台防坠机构及其方法,提出一种牵引件与防坠机构相对位置灵活设计的新方案,以期能够有效地减少安装空间、方便地改变牵引力方向、缩短制动触发时间。升降台防坠机构包括通过螺栓安装在载货台侧臂上的一组水平设置的防坠导柱座,一组导柱的垂向两端平行地安装于防坠导柱座之间,在两侧导柱之间分别套设有滑块,在顶端防坠导柱座与滑块之间、导柱上套设有压缩弹簧,在滑块上安装有链条拉紧座和凸轮拨叉;在载货台侧臂上设置有一组弧形孔、安装有一组凸轮轴,在载货台侧臂侧部连接有牵引件,在牵引件与提升板之间、在套管外部套设有弹簧;在载货台侧臂上垂向地安装一防坠角钢,在防坠角钢之间相对地设置有一对制动凸轮。
