Description
Technical Field
The utility model relates to a bridge is fixed crimping device of super high strength steel wire for cable. Belongs to the technical field of suspension bridge engineering equipment.
Background
At present, the main cable erection method of the suspension bridge mainly comprises two methods: an air spinning process (AS process) and a prefabricated parallel wire strand process (PPWS process). The AS method is a method of knitting a plurality of steel wires into a steel wire strand on a catwalk by taking the steel wires AS a traction unit, and then binding a plurality of strands to form a main cable; the PPWS law uses a strand as a pulling unit, and then ties the strand into a main cable. The main cable strand of the large-span suspension bridge is heavy, the requirement on traction equipment is high, and particularly when the large-span suspension bridge is built in a mountain area where traffic is not available, the PPWS method has larger transportation difficulty than the AS method, so that the AS method is preferred for the construction of the large-span suspension bridge in the mountain area.
For the AS method, because of the endless wire strand, the wires need to be connected to each other by a steel sleeve, and the connection device AS a part of the main cable will participate in long-term load bearing. The main cable wires are supplied in reels, the weight of which does not exceed 2 tonnes at most. From the construction needs, the steel wires have to be lengthened. The conventional wire lengthening structure (wire connector) is of a screw connection type, in which a screw thread is formed by spirally pressing the end of a wire with a left hand and a right hand, and the end is obliquely cut. The two steel wire coils to be lengthened are clamped by pliers and are penetrated into two ends of a sleeve with screw threads. The sleeve is rotated so that the two wire ends to be lengthened are drawn together. At this point, the length of the thread exposed outside the casing is taken into account, and the two chamfered ends are ensured to be abutted, so that when the steel wires are pulled, the chamfered ends of the two steel wires are clamped with each other and cannot be slightly withdrawn due to rotation. The corresponding construction process is that after the ends of the steel wires are inserted into the sleeves, the sleeves are extruded by a hard die (extruded twice according to different directions) until the inner walls of the sleeves are embedded with the surface of the steel wires in a concave-convex mode. The work needs to be finished on site operation on a construction site, the efficiency is low, and the operation quality cannot be effectively guaranteed.
