Description
Technical Field
The invention relates to a cable saddle of a cable crane, in particular to a cable saddle transverse sliding device, a cable saddle system and a transverse sliding method.
Background
In recent years, with the rapid development of large-span bridges, bridge construction methods have also been diversified. The methods have respective advantages and disadvantages, wherein the construction method of the cable crane has the advantages of large spanning capability, small influence on a navigation channel, strong adaptability (vertical hoisting and horizontal longitudinal transportation), turnover use and the like, and is one of the most competitive construction methods of the large-span bridge. The traditional cable crane system moves the cable crane together with the main cable through the tower, the cable crane usually arranges a slideway and a sliding plate at the bottom of the tower, and the cable crane loosens the cable rope at the periphery of the tower when moving, and releases or loosens the connection of the main cable and the ground anchor. The whole tower is dragged to move by using a winch, and the tower can be positioned only by adjusting and moving for many times. The cable crane has complex movement and more movement times, and cannot move back and forth or move with load. In other related researches, a rigid sliding block is arranged at the top end of a tower on one shore of a crane system, and a main cable is embedded in a cable groove of a cable saddle at the top end of the sliding block. The main cable moves by dragging the sliding blocks by the windlasses at the two ends of the tower top. The main cable is directly connected with the rear anchor cable of the anchoring system, so that the main cable, the slider cable rope and the welded part for fixing the slider need to be loosened when the slider moves. After the movable steel wire rope is moved to a proper position, the sliding block is fixed and the main cable is adjusted, so that the construction is not flexible, and the mounting and dismounting workload is large.
The cable hoisting system is mainly used for hoisting sections such as arch rib sections and bridge deck beams, the hoisting positions are inconsistent when the arch rib sections and the bridge deck beam sections are hoisted, and the cable crane can cover the whole bridge range through the transverse movement of the tower top cable saddle. When the arch rib is hoisted, the two groups of main cableways are combined to form a set of large main cableway; when the bridge deck beam segment is hoisted, the two groups of main cable ways are separated, and the four hoisting points work cooperatively to lift and hoist together. The two sets of main ropeways have the functions of cooperative hoisting and independent hoisting.
The traditional cable saddle traversing system mainly adopts a tower and a cable to move a cable crane together, the cable crane is usually provided with a slideway and a sliding plate at the bottom of the tower, and cable ropes at the periphery of the tower are loosened during moving to release or loosen the connection between a main cable and a ground anchor. The whole tower is dragged to move by using a winch, and the tower can be positioned generally by adjusting and moving for many times.
