Intelligent wire releasing device for steel cable stranding

Abstract

The invention discloses an intelligent wire releasing device for steel cable stranding. The device comprises a plurality of wire releasing discs and cable management racks, wherein each wire releasingdisc comprises a base, a rotating frame, a gear motor controlled by a frequency converter, a driving gear and a speed reducing driven gear, a central shaft is arranged on the base, a hollow column isarranged at the center of the rotating frame, the hollow column is in sliding fit with the central shaft through a bearing, the speed reducing driven gear is arranged at the lower part of the rotating frame, and the driving gear engaged with the speed reducing driven gear is arranged on an output shaft of the gear motor; the cable management racks comprise a first cable management rack and a second cable management rack, wherein a floating roller measuring device is arranged between the first cable management rack and the second cable management rack; the floating roller measuring device comprises a mounting rack, floating rollers, displacement sensors and linear sliding rails, wherein a plurality of mounting columns are arranged on the mounting rack; one linear sliding rail is arranged on each mounting column; a sliding block is in sliding fit with the linear sliding rail; each floating roller is arranged on the corresponding sliding block; a balancing weight and a floating distancedetection board are arranged on each sliding block; one displacement sensor is arranged on each mounting column; and the frequency converters, the displacement sensors and a controller are electrically connected.

Description

technical field [0001] The invention relates to the field of bridge construction manufacturing, in particular to an intelligent wire feeding device for stranding steel cables. Background technique [0002] Steel wire cables are an important part of bridges such as cable-stayed bridges and suspension bridges and some building structures. They are load-bearing components and have a direct and important impact on the structural safety and service life of bridges and buildings. With the current development of bridges and buildings, the specifications of cables are also getting larger and larger, and there are large-scale, super-length, high-strength stay cables and suspension cables. Now cables have been widely used in bridges and buildings, and often a project requires dozens or even thousands of unit strands, and each unit strand is composed of hundreds of steel wires. In order to ensure the construction period, such a large number of production tasks must be completed in a v...

Problems solved by technology

In order to ensure the construction period, such a large number of production tasks must be completed in a very short period of time, and the equipment in the production workshop must be increased. The more discs, the harder it is to control

At present, in the production process of steel wire and cable, the wire reel has no power and relies solely on the power of the traction equipment. The control of the wire reel is mainly controlled manually, and manual intervention is required from time to time.

In such a production mode, the production efficiency is limited, the pulling speed of the steel wire cannot be synchronized with the wire feeding speed of the wire reel, and the wire feeding speed of each wire reel will also have a large difference, and the tension of the steel wire cannot be controlled. It will have a certain impact on the quality of the finished cable, and it is also prone to jamming and wire skipping. However, the steel wire itself is elastic, and some wire reels are stuck and skipping wires, which can easily cause the steel wire to entangle with other equipment and even cause accidents to employees. Injury, the safety of employees cannot be guaranteed
