Chain dynamic anti-falling matched rigid dynamic anti-falling device
The invention discloses a device with dynamic chain falling prevention matched with rigid dynamic falling prevention. The device comprises two rear stand columns, a front cross beam, two longitudinal beams, two mounting plates, two bearing seats, a traction driving shaft and a vehicle carrying plate. The two chain dynamic anti-falling units are used for preventing falling at the front end, and the rigid dynamic anti-falling unit is used for preventing falling at the rear end; the left longitudinal beam, the front cross beam, the right longitudinal beam, the traction driving shaft, the left bearing seat and the right bearing seat form an upper-layer rigid frame, so that a rear cross beam is saved; the chain dynamic anti-falling unit comprises a chain wheel, a chain wheel shaft, a traction rope wheel, a traction steel rope, a falling block, a chain and an anti-falling part, the simple mode that the chain directly penetrates through the rear stand column and the chain is matched with the steel rope for traction is adopted, performance is more stable, and manufacturing cost is saved; the rigid dynamic anti-falling unit comprises a left connecting piece, a right connecting piece, a rear connecting piece, a left rigid anti-falling part and a right rigid anti-falling part, and further comprises limiting rollers, the dynamic anti-falling function is achieved, and the lifting operation stability of the car carrying plate is improved.
本申请一种链条动态防坠配合刚性动态防坠的装置，包括两根后立柱、一根前横梁、两根纵梁、两块安装板、两个轴承座、一根曳引驱动轴、一块载车板；还包括前端防坠的两个链条动态防坠单元、后端防坠的一个刚性动态防坠单元；左纵梁、前横梁、右纵梁、曳引驱动轴、左轴承座、右轴承座构成一个上层刚性框架，节省了后横梁；链条动态防坠单元包括链轮、链轮轴、牵引绳轮、牵引钢索、坠块、链条、防坠部件，采用链条直接穿越后立柱以及链条配合钢索牵引的简约方式，性能更稳定，且节省制作成本；刚性动态防坠单元包括左连接件、右连接件、后连接件、左刚性防坠部件、右刚性防坠部件，还包括限位滚轮，具备动态防坠功能且增加载车板升降运行稳定性。
