Abstract

The utility model discloses a kind of anti-rotation alternatelaywirerope, comprise right-laid and left-hand lay, described steel wire rope is made up of the identical right-laid of quantity and left-hand lay, the sth. made by twisting of each adjacent layer stock is on the contrary, namely described right-laid and left-hand lay are alternately arranged, the levels stock of any right-laid is left-hand lay, and the levels stock of any left-hand lay is right-laid.A kind of anti-rotation alternatelaywirerope described in the utility model has the advantage of non-spinning wire rope and Lang lay rope, variantly to be alternately arranged in rope to stock, add the contact surface of steel wire, mechanical property also than non-spinning wire rope and Lang lay rope good, by to Mechanics Performance Testing of the present utility model and adhesion test, select same materials, rupture pull force improves 12% than the non-spinning wire rope of same specification, improves 20% with the bonding strength of rubber than the non-spinning wire rope of same specification.

Description

A kind of anti-rotation alternatelaywirerope

Technical field

The utility model relates to steel wire rope technical field, more particularly, is about a kind of anti-rotation alternatelaywirerope.

Background technology

The breed structure of steel wire rope is a lot, traditional steel wire rope by the sth. made by twisting of left-hand lay and right-laid to being generally divided into ordinary lay and twist-on-twist two kinds.

Its rope of non-spinning wire rope, is twisted with the fingers to dividing sinistral coiling and a dextrad spiral to contrary (as shown in Figure 1) with the sth. made by twisting of stock.If rightlay rope is namely for be twisted into stock by steel wire rope by sinistral coiling, then make rope by stock to dextrad spiral turn.Because rope is contrary with reversing the trend of stock, cancel each other and there is no twist ties, loose trend, use more convenient, be mainly all kinds of lifting at present, elevation and subsidence mechanical adopts, but also have flexibility less, air spots is sliding, little with the contact area of pulley, to wear and tear shortcoming faster, cause using consume larger.

Its rope of Lang lay rope is twisted with the fingers to identical (as shown in Figure 2) with stock, and it is twisted with the fingers to being also divided into left and right sth. made by twisting, is twisted stock as right-laid is silk along wiring, and stock is twisted rope again and is dextrad spiral twisting and forms.The silk of this steel wire rope and the Contact of silk better, have good around property, that the life-span is long feature, but have twist ties, easily loose trend, can only be used for tensioned lines or pull rope, should not be used for lifting and winding rope.

Summary of the invention

Goal of the invention: for the deficiencies in the prior art, my company technique personnel, through repeatedly putting into practice improvement, devise a kind of anti-rotation alternatelaywirerope, the object that the twist stress reaching steel wire rope balances mutually, realize good anti-rotation effect.

Technical scheme: in order to realize foregoing invention object, the technical scheme that the utility model adopts is: a kind of anti-rotation alternatelaywirerope, comprise right-laid and left-hand lay, described steel wire rope is made up of the identical right-laid of quantity and left-hand lay, the sth. made by twisting of each adjacent layer stock is on the contrary, namely described right-laid and left-hand lay are alternately arranged, and the levels stock of any right-laid is left-hand lay, and the levels stock of any left-hand lay is right-laid.

Beneficial effect: compared with prior art, its beneficial effect is the utility model:

1, a kind of anti-rotation alternatelaywirerope described in the utility model has the advantage of non-spinning wire rope and Lang lay rope, variantly to be alternately arranged in rope to stock, add the contact surface of steel wire, mechanical property also than non-spinning wire rope and Lang lay rope good, by to Mechanics Performance Testing of the present utility model and adhesion test, select same materials, its performance change is as follows:

A, rupture pull force improve 12% than the non-spinning wire rope of same specification;

B, improve 20% with the bonding strength of rubber than the non-spinning wire rope of same specification.

2, the utility model can substitute original left-hand lay wire rope and right-hand lay wire rope half and half completely, the situation that combination collocation uses.

Accompanying drawing explanation

Fig. 1 is the structural representation of non-spinning wire rope.

Fig. 2 is the structural representation of Lang lay rope.

Fig. 3 is the structural representation of a kind of anti-rotation alternatelaywirerope of the utility model.

Detailed description of the invention

Below by a most preferred embodiment, the technical program is described in detail, but protection domain of the present utility model is not limited to described embodiment.

As shown in Figure 1, the rope of non-spinning wire rope to the sth. made by twisting of stock to contrary, twist with the fingers to point sinistral coiling and a dextrad spiral.If rightlay rope is namely for be twisted into stock by steel wire rope by sinistral coiling, then make rope by stock to dextrad spiral turn.

As shown in Figure 2, the rope of Lang lay rope to the sth. made by twisting of stock to identical, it is twisted with the fingers to being also divided into left and right sth. made by twisting, is twisted stock as right-laid is silk along wiring, and stock is twisted rope again and is dextrad spiral twisting and forms.

Embodiment:

As shown in Figure 3, a kind of anti-rotation alternatelaywirerope, comprise right-laid 1 and left-hand lay 2, described steel wire rope is made up of 3 bursts of right-laid 1 and 3 bursts of left-hand lays 2, and described right-laid 1 is alternately arranged with left-hand lay 2, i.e. the levels stock of any right-laid 1 is left-hand lay 2, the levels stock of any left-hand lay 2 is right-laid 1, the sth. made by twisting of each adjacent layer stock, on the contrary, makes the twist stress of stock mutually balance, reaches good anti-rotation effect.

The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.

Claims

1. an anti-rotation alternatelaywirerope, comprise right-laid (1) and left-hand lay (2), it is characterized in that: described steel wire rope is made up of the right-laid (1) of equal number and left-hand lay (2), described right-laid (1) and left-hand lay (2) are alternately arranged, namely the levels stock of any right-laid (1) is left-hand lay (2), and the levels stock of any left-hand lay (2) is right-laid (1).
