Technical Field

The invention belongs to special mechanical equipment for steel wire ropes, and particularly relates to steel wire rope line concentration equipment.

Background

In the process of producing the steel wire rope, a plurality of strands of small-diameter steel wires (called strands) need to be twisted together by a wire collecting device to form the large-diameter steel wire rope. The line concentration equipment is generally composed of a line concentration disk assembly and a plurality of line passing modules, wherein the line concentration disk assembly is installed on a rack. After the small-diameter strand wires pass through the wire collecting disc, the strand wires are layered and collected at the positions of the wire passing dies, and then the strand wires are twisted into the rope.

Chinese patent "steel wire rope double twister", publication No. CN203960646U, granted bulletin date 2014.11.26, discloses a steel wire rope double twister, which comprises an inner wire take-up assembly, an outer over-twisting assembly, a wire collecting nozzle assembly, a monofilament pay-off assembly and a core wire pay-off assembly, which are sequentially arranged; the wire collecting nozzle assembly comprises a wire collecting nozzle rack, a wire collecting plate is arranged on the wire collecting nozzle rack, and a plurality of wire collecting nozzles are arranged at the rear end of the wire collecting plate along the wire collecting direction; the wire collecting plate comprises a plurality of layers of annular disc bodies with gradually increasing diameters, and the plurality of layers of annular disc bodies are connected to form the wire collecting plate; a plurality of detachable take-up pulley seats are uniformly distributed on the annular disc body along the circumferential direction, and each take-up pulley seat is provided with a take-up pulley.

The above patents, as well as the prior art hub, generally have problems including:

1. in order to realize convergence of the strand wires towards the center, the two disc bodies are of conical ring structures and need to be positioned and assembled with each other, and the conical rings can only be realized by pressing the locking sleeve through screws. When the strand wires are gathered, traction force is needed, the fluctuation of the traction force can be transmitted to the mounting seat, the disc body of the conical ring and the whole wire collecting disc through the wire winding wheel set, a vibration effect is formed, the loosening of screws is caused, and finally the assembly failure between the disc bodies can be caused.

2. The bottom surface of the reel mounting seat is a plane and is mounted on the conical surfaces of the two conical ring disc bodies, and the problem of unstable mounting is easily caused due to the fact that the contact surfaces are too small.

3. Wear out from the bottom hole of reel mount pad behind the reel, easily because of the strand silk to crossing the improper friction that arouses between strand silk and the wire winding wheelset mount pad bottom hole when the line mould assembles, damage strand silk and wire winding wheelset mount pad.

4. The wire collecting disc is assembled and positioned with the frame only through a plurality of hole sites on the lower part of the wire collecting disc, cantilever installation is formed, and the wire collecting disc is easy to vibrate due to the fluctuation of traction force when a strand wire passes through the wire wheel, so that the stability of the wire collecting disc is greatly not facilitated.

Preferably, the wire passing hole is a waist-shaped hole, and the center line passes through the circle center of the central circular hole.

Preferably, two turns of wire passing holes are formed in the periphery of the central circular hole.

Further preferably, the number of the outer ring wire through holes is larger than or equal to that of the inner ring wire through holes.

It is further preferred that the centre lines of the two turns of the wire passing hole at the same angle are collinear.

Preferably, the frame is provided with two parallel guide rods, and the wire passing die is connected with the guide rods through a wire passing die mounting seat; the wire passing die mounting seat can slide along the guide rod and is fixed through the positioning piece.

The invention has the beneficial effects that: compared with a wire collecting device with a typical structure, the wire collecting disc is changed into a flat plate type, the strand wire passing hole is changed into an elongated waist-shaped hole, and the wire collecting disc and the rack are connected and reinforced by adopting the stabilizer bar.

The invention solves the problem of insufficient stability when the wire collecting disc cantilever is installed by additionally installing the stabilizer bar, eliminates the chain vibration reaction caused by the fluctuation of the traction force on the strand, is more convenient for the installation of the reel base on the wire collecting disc, changes the plane contact between the two, and is more stable and reliable. The flat plate type wire collecting disc adopts the waist-shaped hole, so that the stranded wires can be allowed to be collected at the wire passing die positions at all positions at a larger adjusting angle, and equipment faults and steel wire rope quality damage caused by direct hard contact and friction between the stranded wires and the reel base are avoided.
