With simple structure, low cost, easy implementation and wide application range, the steel wire rope fastening piece is suitable for being widely applied on occasions of decreasing force environments, field works and the like.

Description

The wire rope fastening piece

Technical field

The utility model belongs to the clamp structure field, is specifically related to a kind of wire rope fastening piece.

Background technique

Wire rope is widely used in multiple industries such as machinery, shipbuilding, mining, metallurgy and forestry, such as vertical shaft hoisting, cableway load-bearing, goods loading etc. as a kind of intensity height, good springiness, from heavy and light and flexible good important component.In the prior art, wire rope be used for the lifting, when tying up or drawing, majority is that wire rope is made lasso trick, again lasso trick is drawn or draws extension, when making the wire rope lasso trick, the general bushing type wire rope compacting joint that has single hole or diplopore that adopts pushes connection to the wire rope termination.When adopting the single hole joint, earlier that wire rope is terminal by strand separately, the bifurcation is pitched during into the wire rope rope is done, with sleeve pipe interface is tightened again; When adopting diplopore joint, a hole the earlier end of wire rope being passed joint is bent into ring-type, again this end is passed the another one hole again butt joint carry out cold hobbing and make it plastic deformation to reach fastening effect; Adopt this two kinds of locking methods, not only can only fastening single-strand rope, and also complicated operation, to set up for those inconvenience in the environment or field operation environment of the environment of heavy weight steel wire rope, the power of successively decreasing, the application area of this type of fastening piece also receives limitation greatly.

The model utility content

In view of this, the purpose of this utility model provides a kind of processing ease, with low cost, simple in structure, and load-bearing is good can be used for that the environment of heavy weight steel wire rope is set up in inconvenience, the wire rope fastening piece of the occasions such as force environment or field work of successively decreasing.

Wire rope fastening piece of the present utility model comprises fastener and the fastener hole that runs through along the fastener axis, and described fastener hole is three.

Further, described three fastener holes are equilateral triangle to be arranged, wherein two fastener hole radial communication;

Further, described fastener hole internal surface is along anti-skidding line circumferentially is set;

Further, described fastener cross section is the triangle that seamlessly transits, described three fastener holes and the corresponding setting in leg-of-mutton three angles;

Further, the material of described fastener is a carbon steel.

The beneficial effects of the utility model are:

This wire rope fastening piece comprises fastener and the fastener hole that runs through along the fastener axis, and described fastener hole is three, can carry out fastening to three strand steel wire ropes; In the application, the one, can't set up in the environment of heavy weight steel wire rope at those, can set up three light-duty wire rope, use this wire rope fastening piece to lock, make three wire rope evenly stressed, being equivalent to a heavy weight steel wire rope uses, reduce user cost, the 2nd, be subjected in the force environment successively decreasing, use this wire rope fastening piece can allow the position of stressed maximum use three wire rope, use two wire rope in stressed medium place, steel cable is used in place in stressed minimum, reduces the wire rope expense, and the 3rd, during operation in the open air, only need carry a kind of wire rope adds this wire rope fastening piece again and can satisfy the different bearer requirement, the convenient use.

When using, wire rope fastening piece of the present utility model only needs fastening piece extrusion-deformation to be got final product with the steel wire penetrating fastener hole and with instrument, and simple to operate; Three fastener holes on the fastener are equilateral triangle to be arranged, two fastener hole radial communication wherein, the triangle that the fastener cross section is designed to seamlessly transit, three fastener holes and the corresponding setting in leg-of-mutton three angles; During extruding, three sides of fastener are evenly stressed, and three fastener holes shrink along the fastener axial direction, and the position that fastener hole is communicated with is tightened up and fitted with the wire rope intimate, and its change in shape is well-balanced, and squeezing effect is better; The fastener hole inwall is along circumferentially being provided with anti-skidding line, wire rope being carried out can increase surface friction drag when fastening, prevents that wire rope from skidding off from fastener hole, strengthened fastening effect.

Wire rope fastener constructions of the present utility model is simple, processing ease, with low cost, load-bearing is effective, is suitable for very that the environment of heavy weight steel wire rope is set up in inconvenience, the wire rope of successively decrease force environment or field work occasion is fastening.

Description of drawings

In order to make the purpose of this utility model, technological scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing 1 is the utility model topology view;

Accompanying drawing 2 is that A-A of the present utility model is to sectional view.

Embodiment

Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.

Fig. 1 is a topology view of the present utility model, and Fig. 2 is that A-A of the present utility model is to sectional view.As shown in the figure: the fastener 1 that have fastener hole 2, fastener hole 3 and fastener hole 4 of wire rope fastening piece of the present utility model for adopting carbon steel to make, during use, three strand steel wire ropes to be tightened are passed fastener hole 1, fastener hole 2 and fastener hole 3 respectively, with instrument fastener 1 is clamped from outer surface along axis again and get final product.

Fastener hole 2, fastener hole 3 and fastener hole 4 connect and are equilateral triangle along the axis of fastener 1 and arrange, fastener hole 3 and fastener hole 4 radial communication, during extruding, three sides of fastener 1 are evenly stressed, three fastener holes shrink along the axial direction of fastener 1, the position that fastener hole 3 and fastener hole 4 are communicated with is tightened up and is fitted with the wire rope intimate, and its change in shape is well-balanced, and squeezing effect is better; The inwall of three fastener holes can increase surface friction drag along circumferentially anti-skidding line being set, and prevents that wire rope from skidding off from fastener hole, has strengthened fastening effect; Fastener 1 cross section is the triangle that seamlessly transits, fastener hole 2, fastener hole 3 and fastener hole 4 and the corresponding setting in leg-of-mutton three angles, and fastener is extruded in the process, and the stress that produces on its cross section is less, easier extrusion-deformation.

Wire rope fastening piece in the present embodiment can be used for the environment that those can't set up the heavy weight steel wire rope.During use, set up three light-duty wire rope, use fastener 1 locking, make three wire rope evenly stressed, be equivalent to a heavy weight steel wire rope and use, reduce user cost.

Wire rope fastening piece in the present embodiment also can be used for successively decreasing and is subjected to force environment.During use, this wire rope fastening piece can allow the position of stressed maximum use three wire rope, uses two wire rope in stressed medium place, uses steel cable in the place of stressed minimum, reduces the wire rope expense.

Wire rope fastening piece in the present embodiment also can be used for field work.Only need carry a kind of wire rope during user's field work and add this wire rope fastening piece again and can satisfy the different bearer requirement, the convenient use.
