Problems solved by technology

[0003] For the mobile cable saddle that needs to move back and forth and has a large lateral movement distance, the existing jack jacking or winch traction cable saddle construction technology is used. The lateral movement speed of the cable saddle is slow and the workload is large. , The height of the tower of the cable crane has a great influence

Embodiment Construction

[0035] A large-tonnage cable crane saddle traverse system, such as Figure 1~5 As shown, it includes the first cable saddle 1, the second cable saddle 2, the first group of hoisting machines 3, the second group of hoisting machines 4, the third group of hoisting machines 5, the traversing axle assembly 6, the steel wire rope 7, the reaction seat 8, the steering Axle 9, slip limit block 10, T-shaped slideway beam 11, bearing pin 12.

[0036] The T-shaped slideway beam 11 is arranged on the beam at the top of the tower, the slip limit block 10 and the distribution beam of the cable saddle base are connected together by high-strength bolts, the slip limit block 10 and the T-shaped slideway beam 11 are pinned by the pin shaft 12 Bolt positioning connection.

[0037] Stainless steel plates are welded on the T-shaped slideway beam 11 and the bottom surface of the distribution beam of the cable saddle base, and grease is applied on the T-shaped slideway beam 11 to reduce the frictio...

Abstract

The invention discloses a cable saddle transverse moving system of a large-tonnage cable crane and a cable saddle transverse moving method. In order to overcome influences of the heights of terrain and a tower and achieve transverse moving of a cable crane saddle, the cable saddle transverse moving system comprises one cable saddle or two cable saddles on a T-type sliding rail beam, a third set of winches is arranged on the front side or the rear side of the cable saddle, and at least one set of winch arranged on the left side and the right side of the cable saddle. The left side and the right side of the T-type sliding rail beam are respectively provided with a counter-force base, and the left side and the right side of the cable saddle and the counter-force bases are respectively provided with a transverse moving wheel shaft assembly. Steering wheel shafts are arranged between the transverse moving wheel shaft assemblies and the winches. The T-type sliding rail beam and base distribution beams of the cable saddle are in pin joint. Winch ropes pull the cable saddle to move in a reciprocating mode in the direction of a cross bridge on the top of the tower. According to the system, the length of a winch steel wire rope is reduced, influences of the terrain are overcome, and the requirement of construction situation that upstream and downstream single-width cable cranes bear load and upstream and downstream double-width cable cranes bear load together is met.

Description

technical field [0001] The invention relates to the field of bridge construction engineering, in particular to a cable saddle traversing system and a cable saddle traversing method for a large-tonnage cable crane. Background technique [0002] At present, bridges hoisted by cables have larger spans and more novel structures. In order to realize bridge construction with different axes, mobile cable saddles are usually used to adjust the position of the load-bearing cables of the cable crane on the width of the bridge. [0003] For the mobile cable saddle that needs to move back and forth and has a large lateral movement distance, the existing jack jacking or winch traction cable saddle construction technology is used. The lateral movement speed of the cable saddle is slow and the workload is large. , The height of the tower of the cable crane has a great influence. Contents of the invention [0004] In order to overcome the influence of terrain and tower height and realize...
