Self-adaptive cable wind system of cable crane and using method thereof

Abstract

The invention discloses a self-adaptive cable wind system of a cable crane and a using method thereof, and relates to the technical field of tower cable wind. The self-adaptive cable wind system of the cable crane comprises a tower frame, cable wind equipment and driving equipment, wherein the cable wind equipment comprises a front cable wind mechanism and a rear cable wind mechanism, and the front cable wind mechanism and the rear cable wind mechanism are oppositely arranged on the two sides of the tower frame in the bridge direction; and meanwhile, the upper ends of the front cable wind mechanism and the rear cable wind mechanism are mounted on the tower, and the lower ends of the front cable wind mechanism and the rear cable wind mechanism are anchored; the driving equipment and the front cable wind mechanism are arranged on the same side, and the driving equipment comprises a front driving mechanism and a rear driving mechanism; the front driving mechanism is connected with the front cable wind mechanism and is used for driving the front cable wind mechanism to pull the tower frame forwards; and the rear driving mechanism comprises a hoisting cable and a lifting appliance, wherein the hoisting cable is connected with the free end of the rear cable wind mechanism, and the lifting appliance is connected with the hoisting cable. The self-adaptive cable wind system of the cablecrane has the advantages that the peak value of the unbalanced horizontal force of the tower top of the tower frame in the bridge direction can be reduced, the horizontal deviation displacement of the tower frame is reduced, the structure is simple, the stress is clear, and the cost is saved.

Description

technical field [0001] The present application relates to the field of tower cable wind technology, in particular to an adaptive cable wind system for a cable crane and a method for using the same. Background technique [0002] In the cable crane, the tower is the main load-bearing structure, the main cable is applied as the main external load on the saddle at the top of the tower, and the horizontal inclination angle of the main cable on the side span is much larger than that on the middle span. In addition to the vertical load, the external load on the tower also has unbalanced horizontal loads. In order to ensure that the strength of the tower and the horizontal deviation of the top of the tower meet the requirements, a rear cable connecting the tower and the cable wind anchor is generally installed. wind mechanism. [0003] Among them, the cable force of the main cable varies greatly under different working conditions of no-load and heavy-load, which also leads to a gre...
