Steering cable saddle for large-tonnage cable crane

Abstract

The invention discloses a steering cable saddle for a large-tonnage cable crane. The steering cable saddle aims at solving the problems that existing movable type cable saddle towers are equipped with a plurality of front and back wind cables along bridge directions and high in cost, and service lives of bearing cable axle assemblies, hoisting cable axle assemblies, traction cable axle assemblies, bearing cables, hoisting cables and traction cables are short. The steering cable saddle comprises cable saddle base distribution beams and a cable saddle base connecting cross beam, wherein each cable saddle base distribution beam is provided with a bearing cable axle assembly, a bearing cable steering device, a hoisting cable steering device, a traction cable axle assembly, a traction cable steering device and a sliding axle assembly; the cable saddle base connecting cross beam is provided with a hoisting cable axle assembly; and the cable saddle base distribution beams are positioned on left and right sides of the cable saddle base connecting cross beam. By means of the steering cable saddle for the large-tonnage cable crane, service lives of the bearing cable axle assemblies, the hoisting cable axle assembly, the traction cable axle assemblies, bearing cables, hoisting cables and traction cables are prolonged.

Description

technical field [0001] The invention relates to the field of bridge construction engineering, in particular to a steering saddle for a large-tonnage cable crane. Background technique [0002] At present, bridges hoisted by cables have larger spans and more novel structures; fixed cable saddles are used, and the position of the load-bearing cables on the width of the bridge cannot be adjusted during construction. [0003] In the existing mobile cable saddle, hoisting ropes and pulleys are generally arranged on both sides of the tower top. The pulley is turned sideways, and then the winch is advanced along the vertical direction of the tower. This structural system arrangement leads to an increase in the unbalanced horizontal force of the hoisting cables and traction cables on the tower along the bridge direction, and the tower is arranged along the bridge. The number increases and the cost increases; and after the cable saddle moves laterally, the load-bearing cable and the...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the unbalanced horizontal force of the tower along the bridge due to the steering of the hoisting cable and the traction cable in the existing mobile cable saddle, the tower will be arranged along the bridge forward and backward, and the cost is high. The cable and traction cable are not stressed in the same axial plane as the axle assembly after the saddle moves laterally, so that the load-bearing cable axle assembly, hoisting cable axle assembly, traction cable axle assembly and load-bearing cable, hoisting cable, and traction cable are used. Due to the short life span, the present invention aims to provide a steering cable saddle for a large-tonnage cable crane. The axle assembly and the traction cable axle assembly are integrated, and the cable saddle is moved in the direction of the bridge on the top of the tower through the traction of the hoist to move the axle assembly to meet the requirements of different positions of the load-bearing rope of the cable crane; The device and the hoisting cable steering device adjust the stress on the same plane of the hoisting cable and the hoisting cable axle assembly, the hoisting cable and the hoisting cable axle assembly, and the hoisting cable and the hoisting cable axle assembly after the saddle is moved laterally. It can prolong the service life of load-bearing cable axle assembly, hoisting cable axle assembly, traction cable axle assembly and load-bearing cable, traction cable and hoisting cable
