Description
Technical Field
The invention belongs to the technical field of suspension bridge main cable winding, and particularly relates to a pre-clamping mechanism and a pre-clamping method for a follow-up steel wire rope of a winding machine.
Background
With the rapid development of society, the main span of the suspension bridge is longer and longer, and the diameter of a corresponding main cable is also larger. In the construction process of the suspension bridge, one of the most important links of the suspension bridge during the construction of the main cable, whether the linear control of the main cable meets the requirement or not, and the structural stress of the whole suspension bridge after system conversion is determined; the main push-towing rope is composed of a plurality of steel wires, and after the main push-towing rope is erected, the main push-towing rope needs to be wound, so that the porosity and the circularity of the main push-towing rope are guaranteed.
Because main push-towing rope diameter grow, steel wire quantity increases violently, and when the main push-towing rope twined the silk, the main push-towing rope appears bulging very easily, the porosity is too big, perhaps the main push-towing rope shape is polygon or oval, makes the adjacent steel wire in close contact with who twines the silk to reach the main push-towing rope guard action. In the prior art, a steel wire rope and a chain block are generally adopted to manually pre-tighten a main cable of a suspension bridge, and the porosity target of the pre-tightened cable is generally 18% -20%. In order to reduce the gap between the steel wires and accelerate the shaping of the steel wires in the pre-tightening process, a wooden hammer or a rubber hammer needs to be manually held to beat the steel wires on the surface discontinuously. The method has the defects of high personnel operation intensity, high labor force demand, low operation efficiency and the like. And the larger the diameter of the main cable is, the more difficult the manual pre-tightening operation is to achieve the required void ratio target. China CN 109338888A is a suspension bridge main cable pre-tightening device and a use method thereof, wherein a walking traveling crane is controlled by a limiting block to move, and a pre-tightening cable device is tightened by the rotation of a circular handle, so that the pre-tightening cable operation of a main cable is realized. However, the structure needs to be disassembled during the installation of the main cable of the device, and the pre-tightening device is of a frame structure, so that the porosity and the circularity of the main cable cannot be ensured, and the main cable cannot be pre-tightened in all directions.
