Description

Winding device for prestressed steel strand bundle

technical field

The invention relates to the field of prestressed steel strand processing, in particular to a winding device for a prestressed steel strand bundle.

Background technique

During the bundling process of the steel strands, in order to prevent the strands from being scattered, it is necessary to bind a plurality of steel strands with iron wires in the outer ring. The current winding equipment mainly includes that the bound object does not move, and the winding device rotates forward to wind it. This way of winding is too dense and the efficiency is low. There are also some windings that use frequency converters and manipulators to complete the winding. This method has a complex structure and is more expensive.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a winding device for prestressed steel strand bundles with simple structure, uniform winding and fast winding speed, which is wound around a plurality of steel strands and bundled in rotation. .

The technical solution to solve the above technical problems is: a winding device for prestressed steel strands, the winding device includes: a bracket, a winding disc is arranged in the inner hole of the bracket, and a plurality of winding discs are arranged at intervals The fixed wheel is hinged and supported, and the fixed wheel is hinged on the bracket; there is a central hole through the steel strand bundle on the winding reel; on the front side of the winding reel, there are: a wire wheel wrapped with a wire rope and a wire sleeve passing through the wire rope; A driven sprocket is fixed on the rear side of the winding reel, the chain is sleeved on the driven sprocket and the driving sprocket, and the driving sprocket is contained in the output end of the motor reducer.

The preferred solution is: the fixed wheel is hinged in the middle of the pin shaft of the fixed wheel, the two ends of the pin shaft of the fixed wheel are respectively fixed on the lower part of the lifting lug, and the upper part of the lifting lug is fixed on the bracket.

The preferred solution is: the wire wheel is hinged on the fixed shaft of the wire wheel, and the bottom of the fixed shaft of the wire wheel is fixed on the front side of the winding reel.

The wire sleeve is a sleeve with a central hole, and the outer diameter of the wire sleeve is welded and fixed on the front side of the coil.

The beneficial effects of the present invention are:

1. The invention cooperates with the uniform speed rotation of the steel wire rope driven by the rotation of the winding reel and the uniform speed advancement of the steel strand bundle to complete the winding action of the steel wire rope around the steel strand bundle. The winding is uniform and the applicability is strong.

2. The present invention has simple structure, fast winding speed and low cost.

detailed description

The embodiments of the present invention are further described in detail below.

As shown in the figure, the present invention provides a winding device for prestressed steel strands, the winding device includes: a bracket 1, a winding disc 4 is arranged in the inner hole of the bracket 1, and the winding discs 4 are arranged at intervals A plurality of fixed wheels 3 are hingedly supported, and the fixed wheels 3 are hinged on the support 1;

A central hole 4a penetrating through the steel strand bundle 5 is arranged on the reel 4 .

On the front side of the winding reel 4 are provided with: a wire wheel 8 wrapped with a wire rope 12 and a wire sheath 6 passing through the wire rope 12 .

A driven sprocket 11 is fixed on the rear side of the winding reel 4, and the chain 9 is sleeved on the driven sprocket 11 and the driving sprocket 13, and the driving sprocket 13 is contained in the output end of the motor reducer 10.

Described fixed wheel 3 is hinged in the middle part of fixed wheel pin shaft 2, and the two ends of fixed wheel pin shaft 2 are respectively fixed on the lower part of lifting lug 14, and the top of lifting lug 14 is fixed on the support 1.

The wire wheel 8 is hinged on the wire wheel fixed shaft 7, and the bottom of the wire wheel fixed shaft 7 is fixed on the front side of the winding reel 4.

The wire sleeve 6 is a sleeve pipe with a central hole, and the outer diameter of the wire sleeve 6 is welded and fixed on the front side of the coil 4 .

More specifically, the outer circle of the reel 4 is hingedly supported by four uniformly distributed fixed wheels 3 , and the reel 4 rotates freely along its axis; the four fixed wheels 3 are hingedly supported by the lifting lugs 14 fixed on the bracket .

Steel strand 5 is conveyed by continuous conveying equipment (not shown), and moves at a constant speed through central hole 4a of winding reel 4,
