The invention discloses an automatic cable passing clamp walking system of a cable crane. The cable crane comprises a main beam, two walking end beams and a traction walking system. The two ends of the main beam are hinged to the walking end beams. The two walking end beams fall on two main cables of the suspension bridge, and a plurality of cable clamps are arranged on the main cables; and a plurality of walking wheels are arranged in one walking end beam, and jacking and retracting of the walking wheels are achieved through stretching and retracting of a lifting oil cylinder. Each traction walking system comprises a traction winch, a traction anchoring point, a fixed pulley block, a movable pulley block and a plurality of proximity switches, wherein the proximity switches are arranged at the bottoms of the end beams, and the front side and the back side of each walking wheel is provided with one proximity switch. The position relation between the walking wheel and the cable clamp can be automatically detected, automatic cable clamp passing walking of the cable crane is achieved, and the problem that cable clamp passing operation of an existing cable crane is tedious is solved.
一种缆载起重机的自动过索夹行走系统,缆载起重机包括一个主梁、两个行走端梁、一套牵引行走系统;主梁的两端与行走端梁铰接;两行走端梁落于悬索桥两根主缆上,主缆上设有多个索夹;一个行走端梁内部设有若干个行走轮,行走轮通过升降油缸的伸缩实现顶升与缩回;单套牵引行走系统包括一个牵引卷扬机、一个牵引锚固点、一个定滑轮组、一个动滑轮组、以及若干个接近开关组成;接近开关设于端梁底部,每个行走轮的前、后方各设一个接近开关。可自动检测行走轮与索夹之间的位置关系,实现缆载起重机的自动过索夹行走,解决以往缆载起重机过索夹操作繁琐的问题。
