Hydraulic traction pay-off system of cable crane

Abstract

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.

Description

technical field [0001] The invention relates to a hydraulic traction pay-off system of a cable crane. Background technique [0002] In the past, cable cranes generally used electric winches for traction and pay-off. The working method was as follows: the winch at the pay-off end relied on visual observation and manual operation to pay out a certain distance in advance, and then used the winch at the draw end to pull a certain distance, and repeated the above steps. , to achieve long-distance traction for walking. When using this method, on the one hand, the operation is cumbersome, relying on the operator's naked eye observation and manual operation; on the other hand, the setting-out and pulling cannot be carried out at the same time, which affects the work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic traction and pay-off system for a cable crane, so that the hoist at the pay-off end can perform automatic p...
