Description

Horizontal converging and horizontal beam-splitting method for parallel steel wire strands

The present invention relates to the field of methods for transporting or installing thin or filamentary materials for storage and re-discharging, re-storage for special purposes, providing various lengths of material, in particular a horizontal bundle of parallel strand strands And horizontal beaming methods. Background technique

The main cable unit cable strand is the main load-bearing member of the suspension bridge. The unit strands are generally bundled from 5mm series high-strength galvanized steel wire. In the past, the unit strands were generally 61 filaments, 91 filaments and 127 filaments. The specifications of the main cable unit are up to (D5mm X 5000m X 169 wire, the weight of the single unit cable strand is 120 tons, the cross section of the unit cable strand is generally a regular hexagon, and some special strands can also be rectangular or other shapes, unit The cable strands are wrapped with a composite tape every 1.5m~2m. Traditionally, the technology of winding large-diameter steel plates to wind the horizontal wire is used in the winding process of the main cable unit at home and abroad. One of the characteristics of the plate-making process is that the production, transportation and release of the strands are inseparable from the large-diameter steel plates. In the process of transporting the stocks to the bridge site, the stocks are due to their own weight. An oval pendant will be produced, as shown in Fig. 1, because the cable strand 10 produces an oval pendant, so that the cable strand 10 is loosely wound, and friction occurs between the strands when the steel disc rotates; the strands continuously follow the steel disc Rotate In the process, this kind of pendant will produce a so-called "hula hoop" effect, which will disturb the order in which the bundled strands should be arranged, so that the bundles are difficult to pull out during the unwinding; The loose strands are suddenly loose and loose, and the friction between the strands is more intensified, causing the belt to be scratched until it breaks, causing the strands to be loose. The remedy is to artificially shape and dress the strands on site. The hula hoop that has already been formed should be shut down and then put out, which not only brings great inconvenience to the assembly and molding of the main cable, but also affects the construction period. The "hula hoop" phenomenon that occurs during the lasso process will As the leasing process progresses, the amount of slack will gradually increase, and the strands will collide with the ground until the construction of the cable is not working properly. Especially when the length of the strand is longer, " The hula hoop phenomenon is more serious, and the longer the length of the strand is, the more difficult the remedial measures will be, or even impossible. According to experience, under the premise that the shape of the strand is kept good, the disc forming process is used. The length is more than 1500m, and the phenomenon of "hula hoop" is easy to occur when the rope is released. In serious cases, the construction progress and the quality of the stock are directly affected.

In order to overcome the defects of the prior art, a beam discharging method with high working efficiency, high retracting quality and low labor intensity is provided, and the invention discloses a horizontal beam converging method and a horizontal beam releasing method for parallel steel wire strands. .
