Abstract

The utility model relates to a combined wire branching device which is used while contacting a spanning wire with a strand of steel wire rope and is characterized in that the combined wire branching device comprises a plurality wire branching discs, a hollow shaft and locking nuts; the wire branching disc is provided with wire branching holes which are designed according to the amount of steel wire layer of the strand, the amount of the wire branching disc is equal to that of the steel wire layer within the strand, the wire branching discs are orderly arranged on the hollow shaft in descending order according to the amount of the steel wire layer and are respectively fixed by means of locking nuts and the difference between the amounts for the wire branching holes which are arranged on the adjacent branching discs is one. The wire branching holes which are arranged on the same layer within the wire branching holes of each wire branching disc are arranged on the same line. Compared with the prior art, the combined wire branching device provided by the utility model has the advantages that the wire branching device can be flexibly combined according to the structure of steel wire rope, the steel wires of each layer are separated, the misplacement problem for the contact between the wire and the steel wire of each layer of the strand of steel wire rope is solved, the operation is simple, the device cannot be damaged easily, the misplacement phenomenon while contacting the wire with the steel wires of different layers of the strand of steel wire rope is prevented, the quality of the product is improved, the tension for the steel wire of each layer within the strand of steel wire rope is coincident and the stress of the steel wire is uniform.

Description

A kind of combined type branch means

Technical field

A kind of combined type branch means that the utility model uses when relating to twisting linear contact lay wire rope rope strand.

Background technology

The linear contact lay wire rope rope strand is made up of some steel wires, the rope strand twisting generally will use noseplate that each root steel wire is sequential separately, twist with the fingers into the linear contact lay wire rope rope strand, steel wire generally from inside to outside concentric circles be arranged with 2～5 layers, the steel wire diameter difference of each layer, the disposable thigh that is twisted into of each layer steel wire, prior art is to use a noseplate at present, the several layers concentric holes is arranged on the noseplate, corresponding with each layer of the thigh steel wire number that needs twisting, have plenty of and between different steel wire floors, use steel traveler that each layer steel wire is spaced apart.Its weak point is: 1) because require the disposable thigh that is twisted into of each layer steel wire, the very easy generation of the steel wire between different layers misplaces and causes the steel wire rope rope strand defective like this, returns car and repairs.2) the employing steel traveler that has is spaced apart with each layer steel wire, though play a role, operation trouble comparatively, and steel traveler is easily broken and bring in the rope strand, so also be of little use now.

Summary of the invention

The purpose of this utility model provides a kind of combined type branch means, and is according to the steel cord structure flexible combination that each layer rope strand steel wire is spaced apart, solves the problem of each layer of linear contact lay wire rope rope strand steel wire dislocation.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of combined type branch means, comprise a plurality of noseplates, hollow shaft, locking nut, be distributed with separated time hole on the described noseplate according to the steel wire number of plies design of rope strand, there is which floor steel wire that several noseplates just are set in the rope strand, a plurality of noseplates are successively set on the hollow shaft from big to small by the steel wire number of plies and fix by locking nut respectively, and the separated time hole number of plies differs one deck on the adjacent noseplate.

Same layer separated time hole, separated time hole on described each noseplate is on same straight line.

Compared with prior art, the beneficial effects of the utility model are: can be according to the steel cord structure flexible combination, steel wire more than each layer is spaced apart, solve the problem of each layer of linear contact lay wire rope rope strand steel wire dislocation, simple to operate, not fragile, do not interlock between the different layers steel wire when having guaranteed that the linear contact lay wire rope rope strand is produced, improved product quality, guarantee that each layer steel wire tension unanimity in the steel wire rope rope strand, steel wire stress are even.

Description of drawings

Fig. 1 is the line contact rope strand example structure schematic diagram of the two-layer steel wire of the utility model coiling.

Among the figure: the little noseplate 5-of the big noseplate 3-of 1-hollow shaft 2-cover wire 4-twisting awl 6-Forming die 7-locking nut 8-steel wire of internal layer 9-locking nut 10-rope strand

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:

See Fig. 1, line contact rope strand embodiment with the two-layer steel wire of coiling illustrates a kind of combined type branch means, comprise big noseplate 2, little noseplate 4, hollow shaft 1, locking nut 7, locking nut 9, be distributed with two-layer separated time hole on the big noseplate 2, be distributed with one deck separated time hole on the little noseplate 4, the setting principle of noseplate is according to there being which floor steel wire that several noseplates just are set in the rope strand, the separated time hole number of plies differs one deck on the adjacent noseplate, and big noseplate 2 and little noseplate 4 are successively set on the hollow shaft 1 and are fixing by locking nut 7 and locking nut 9 respectively.Separated time hole on described big noseplate 2 and the little noseplate 4 is located on the same straight line with layer separated time hole.

In the use of the present utility model, hollow shaft 1 is connected with head, big noseplate 2 is near head, little noseplate 4 is arranged in order, and the cover wire 3 of rope strand passes the outer separated time hole of big noseplate 2 earlier, and cover wire directly enters twisting awl 5 then, steel wire of internal layer 8 is lowered to the internal layer separated time hole of big noseplate 2, pass the separated time hole on the little noseplate 4 more successively, also enter Forming die 6 then, converge at Forming die 6 places and be twisted into rope strand 10 by twisting awl 5.

To calculate each layer steel wire spiral angle during design, and the separated time orifice angle that guarantees big noseplate 2 can not scratching when making cover wire enter the twisting awl by next noseplate to little noseplate.Steel wire of internal layer 8 will be avoided with cover wire 3 dislocation taking place to twisting awl 5 again by little noseplate 4 and produce quality accident.

Claims

1. combined type branch means, it is characterized in that, comprise a plurality of noseplates, hollow shaft, locking nut, be distributed with separated time hole on the described noseplate according to the steel wire number of plies design of rope strand, there is which floor steel wire that several noseplates just are set in the rope strand, a plurality of noseplates are successively set on the hollow shaft from big to small by the steel wire number of plies and fix by locking nut respectively, and the separated time hole number of plies differs one deck on the adjacent noseplate.

2. a kind of combined type branch means according to claim 1 is characterized in that, same layer separated time hole, the separated time hole on described each noseplate is on same straight line.
