The invention discloses a hydraulic traction pay-off system of a cable crane. The hydraulic traction pay-off system comprises two cable bent towers, a plurality of bearing cables, a plurality of bearing cable guide pulleys, two bearing cable anchoring points, a crane carriage, a plurality of traveling wheels, two winches, two traction steel wire ropes and two traction steel wire rope guide pulleys. The cable bent towers stand on the ground; the plurality of bearing cable guide pulleys and one traction steel wire rope guide pulley are arranged at the top of each cable bent tower; the two ends of each bearing cable are anchored to the bearing cable anchoring points respectively and pass through the bearing cable guide pulleys on the tops of the two cable bent towers; one end of the traction steel wire rope is fixed on the winch roller, and the other end is fixed on the crane carriage and passes through the traction steel wire rope guide pulley at the top of one cable bent tower; the plurality of walking wheels are arranged on the crane carriage, annular grooves are formed in the walking wheels, and the grooves are clamped on the bearing cable; when the traction system is used for traction, the crane carriage can walk back and forth along the bearing cable through the walking wheels; the whole cable crane traction system is symmetrically arranged; and a single winch is driven by a hydraulic motor. The winch at the pay-off end performs constant-tension automatic pay-off, traction and pay-off actions can be automatically and synchronously performed, and manual pay-off operation is not needed, so that the working efficiency is greatly improved.

    一种缆索吊机的液压牵引放线系统,缆索吊机牵引系统包括两个索塔、若干根承重索、若干个承重索导向滑轮、两个承重索锚固点、一个起重跑车、若干个行走轮、两个卷扬机、两根牵引钢丝绳、两个牵引钢丝绳导向滑轮,索塔立于地面,每个索塔顶部设置若干个承重索导向滑轮和一个牵引钢丝绳导向滑轮;承重索的两端分别锚固于承重索锚固点,并通过两个索塔顶部的承重索导向滑轮;牵引钢丝绳一端固定在卷扬机滚筒上,另一端固定在起重跑车上,并通过一个索塔顶部的牵引钢丝绳导向滑轮;起重跑车上设有若干个行走轮,行走轮上设有环形凹槽,将凹槽卡于承重索之上,当牵引系统牵引时,起重跑车即可通过行走轮沿着承重索前后行走;缆索吊机牵引系统整体为对称布置;单个卷扬机由一个液压马达驱动。使得放线端卷扬机进行恒张力自动放线,牵引与放线动作能够自动同步进行,无需人工操作放线,大幅提升工作效率。
