Description

Horizontal winding and horizontal unwinding of parallel wires {METHOD FOR HORIZONTALLY WINDING AND UNWINDING A PARALLEL WIRE STRAND}

The present invention applies to a method of transporting and installing slim or thin materials of various lengths for special purposes used for storage, re-release and re-storage, and in particular, to a method of horizontal winding or unwinding a kind of parallel wire.

The main cable wire is the major supporting weight of the suspension bridge, and the unit wire is typically a bundle of 5mm series high strength galvanized wire. Existing unit wire sizes are generally 61, 91 and 127, and the main cable unit wire size, which is currently the extra large length, reaches Φ 5mm × 5,000m × 169 and the single unit wire reaches 120 tons. It is a regular hexagon of the cut surface of unit wire. Partial special wire can be square or other shape. Unit wire is packed with compound belt at 1.5M ~ 2m distance. Traditionally, the winding method of the main cable unit wires at home and abroad applies all the technology of winding the horizontal wiring with a large diameter steel sheet, which is called a disk method. The special feature of the disk method is that large diameter steel disks are required for wire production, transportation and wire laying. In the process of transporting the disk wire to the bridge site, due to the weight of the wire itself, the wire becomes elliptical, as shown in FIG. As the wire 10 stretches in an elliptical shape, the winding of the wire 10 is loosened, friction occurs between the wires when the steel disk is rotated, and the wire is continuously rotated along the steel plate, so that the loose portion exhibits a "hula hoop" effect. Pulling the wire becomes very difficult because the array of wound wires is scattered. When releasing the wires, the loosening force tightens and loosens the loosely wound wires, which increases the friction between the steel wires and damages or ruptures the packing belt, causing the wires to scatter. The recovery method must be artificially adjusted or banded to the wire in the field, and the part that has already formed the "hula hoop" is very inconvenient to assemble the cable because it has to be stopped and pulled out of the facility and more severely during the construction period. It affects. In the process of loosening, the "hula hoop" phenomenon becomes more severe and loosening in the process of loosening, the wire is in contact with the ground, the construction can not proceed normally. Especially for very long wire lengths, the "hula hoop" phenomenon is more severe, and the longer the wire, the more difficult the recovery action and ultimately cannot proceed. Based on experience, when using the disk method under the condition that the wire shape is in good condition, the general wire length is more than 1500m, and when the wire is unwound, it is easy to "hula hoop" phenomenon, which severely affects the construction progress and the quality of the wire. do.

In order to overcome the deficiencies of the existing technology, the present invention provides a method of unwinding and winding a kind of parallel steel wire in order to provide a method of unwinding and winding a wire having a high work efficiency, a high quality of unwinding and winding, and a low labor intensity.
