Description

Technical Field

[0001] The utility model relates to cable strand steel wire positioning, in particular to the production of prefabricated main cable strands for suspension bridges, and belongs to the technical field of bridge construction engineering and metal product processing. Background Art

[0002] The main cable of a suspension bridge is composed of multiple cable strands. The current common technology is to prefabricate the main cable strands in the factory. That is, several galvanized steel wires are prefabricated into regular hexagonal cable strand cross-sections in the factory. This mainly includes the production and arrangement of marking steel wires and standard steel wires, as well as the wire-laying and forming process. The strands are then prefabricated into quadrilateral cross-sections at positions corresponding to the main and loose cable saddles for easy saddle insertion. The ends of the strands are anchored with hot-cast anchors, then coiled and transported to the site for installation.

[0003] When laying out and bundling the main cable strands, the existing technology involves machining hexagonal holes in a plate to constrain the strand wires. This process often results in misalignment, tangling, wear, and bending of the high-strength galvanized steel wires, seriously impacting cable quality and production efficiency. Utility Model Content

[0004] The present invention aims to design a cable strand steel wire positioning device and a set of devices that can meet the cable strand steel wire positioning method, so as to solve technical problems such as steel wire misalignment, twisting, wear, and bending during cable strand production.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A cable strand wire positioning device, which is composed of a frame, a fixing part, and an axis; the axis is composed of a vertical axis and a horizontal axis; the vertical axis and the horizontal axis are respectively fixed by a bearing seat and a bearing on the inside of the frame and can be rotated by themselves; a wire threading hole is formed between the vertical axis and the horizontal axis; corresponding horizontal and vertical coordinate marks are set on the top edge and side edges of the frame corresponding to the wire threading holes.

[0007] The positioning device can be provided in 1 to 2 groups according to needs.

[0008] The utility model designs a set of devices that can meet the cable strand steel wire positioning method. Multiple groups are arranged at the cable strand clustering die. The device of the cable strand steel wire positioning method is marked with the horizontal and vertical coordinates corresponding to the corresponding wire threading holes. The horizontal axis and the vertical axis of the wire threading holes can rotate freely relative to each other, and only rolling friction is generated between them and the high-strength galvanized steel wire, which can well protect the coating and improve the corrosion resistance and service life of the galvanized steel wire.

[0009] Determine the number of the high-strength galvanized steel wire, and pass the high-strength galvanized steel wire with the corresponding number through the corresponding hole determined according to the horizontal and vertical coordinates marked on the cable strand steel wire positioning method device, so as to achieve the purpose of cable strand steel wire positioning distribution. The operation is simple and error-prone. BRIEF DESCRIPTION OF THE DRAWINGS

First, the pay-off drum 11 at the lower end is numbered 1 and 2, and the pay-off drum 11 at the upper end is numbered 3 and 4. Then, the pay-off drum 11 adjacent to the lower end is numbered 5 and 6, and the pay-off drum 11 adjacent to the upper end is numbered 7 and 8, and so on.

[0023] Step 2: calibrate the number of the high-strength galvanized steel wire 9 to be consistent with the number of the pay-off reel 11;

[0024] Step 3: By comparing the cable strand wire numbers with the coordinate comparison table of the positioning device frame, manually pull the high-strength galvanized steel wire 9 through the corresponding holes 2 determined by the horizontal and vertical coordinates marked on the frame 1 of the upper and lower end positioning devices 10 in the schematic diagram before the cable strand wire shaping step;
