Description

Hoist cable is compiled the processing structure of spigot portion

Technical field

The hoist cable that the present invention relates on a kind of suspension hook that hangs over crane or lift etc., uses when hanging heavy articles relates in particular to the hoist cable that forms the part that hangs over the ring-type of using on the suspension hook and compiles the processing structure of spigot portion.

Background technology

In general, this kind hook hoist cable is to form the collar to use at the two ends of cable wire, as its formation method:

(1) makes the two ends of cable wire become parallel state of unfolding, this position is fixed (locking processing) with crimping with the sleeve crimping.

(2) will be known as and twist the strand connect the collar (twisting into the processing of sweet potato shape) and wire harness to compile slotting method be general method.

But the shortcoming of the locking processing method of above-mentioned (1) is, be not easy bending because of the sleeve of institute's crimping is very hard, so for the very weak and easy damage of impressed pressure, or problems such as the durability that produces because of internal corrosion is not good take place in the service condition that causes of reason using method or environment (by the seawater etch etc.) easily.In addition, because crimping is thicker than rope diameter with sleeve diameter, so can block with other article or when putting into the taking-up hoist cable and slinging, operate and want spended time.

Above-mentioned (2) stubborn connects collar processing, be will the strand of multiply twist close formation cable wire by the end bending, and method from its end being compiled the strand that exposes the part of the stubborn sth. made by twisting that is inserted in cable wire or wire harness, cutting off with cutting tools such as pliers or cutting nippers.

But, to do like this, the end of being cut off still can be exposed, if health is run into sharp-pointed leading section when lifting operation, even the band gloves still have injured danger.

In order to address the above problem, have in the volume of exposing the end of cutting off and insert on the part, the method for fixing, or winding steel wire (protective wire) with the pyrocondensation sleeve is shunk, the volume that expose the end that the quilt of parcel is cut off is inserted the method for part.

" patent documentation 1 " spy opens flat 5-132881 communique

" non-patent literature 1 " civic organization Japan mechanics can be issued, and mechanical engineering brief guide changes fixed the 5th edition the 16th and compiles.

But the volume of exposing in the end that above-mentioned quilt is cut off is inserted on the part, makes the structure of pyrocondensation sleeve shrink wrapped, owing to the thin thickness of pyrocondensation sleeve, wear no resistance, destroyed so will soon wear and tear or damage, the problem of influential its durability.

In addition, the method for the slotting part of volume that expose the end that the quilt of winding steel wire and parcel is cut off if cut off in a part of compiling the steel wire of inserting the part winding, then can produce the problem of durability because of scattering.

By motion, its purpose is to provide a kind of hoist cable to compile the processing structure of spigot portion in view of stating problem points in the present invention, and the volume of exposing in the end of cutting off is inserted on the part and wrapped up protective wire, and can increase substantially the durability of this protective wire.

Summary of the invention

For addressing the above problem; hoist cable of the present invention is compiled the processing structure of spigot portion; it is characterized in that: close and form the crooked and stubbornly close part, form stubborn connecing on the hoist cable of the collar partly cutting off of cable wire will twisting from the outstanding strand of cable wire with what cable wire was enrolled in its end by the end by many strands; the protective wire of on the external peripheral zone that enrolls part that is exposed by the end face of the hoist cable cut off, reeling, and this protective wire is fixed with synthetic resin.

In addition, compile in the processing structure of spigot portion at hoist cable of the present invention, it is characterized in that: synthetic resin is to be used to represent synthetic resin kind, that be colored; With single line coiling hinge lines.

(invention effect)

In the present invention; covering protection line on the external peripheral zone that enrolls part that will expose at the end face of the strand of being cut off; and fix this protective wire with synthetic resin; therefore; even the part of protective wire disconnects; protective wire also can keep the state by the synthetic resin secure fixation, thus, the phenomenon of scattering as the structure of the steel wire of just being reeled can not occur.Thereby, can improve the durability of hoist cable greatly.

In addition; the synthetic resin that the protective wire of reeling on the external peripheral zone that enrolls part that will expose at the end face of the strand of being cut off is fixed; compare highly low with the structure of fixing with the sleeve crimping; so; this synthetic resin part is compared extremely thin with the structure that the crimping of using is in the past fixed with sleeve; can be as not in the past, block or snarl with other article, have and therefore can reduce hoist cable significantly and put into and take out or the advantage of the operating time when hanging heavy articles.

And according to the flexibility of the synthetic resin part of fixing protective wire, the cable wire of this part also has flexibility, can be further easily and carry out hoist cable simply and put into and take out or the operation when hanging heavy articles.

The specific embodiment

Below, illustrate that with reference to the accompanying drawings hoist cable of the present invention compiles the preferred embodiment of the processing structure of spigot portion.

Fig. 1 is the stereogram of hoist cable, symbol 1 expression hoist cable integral body among the figure.

This hoist cable 1 forms the

stubborn collar

3,3 parts that connect on the suspension hook that hangs over crane or lift etc. in the two end portions of cable wire 2.

Above-mentioned cable wire 2, the detailed diagram of having omitted, this cable wire is to be twisted with the fingers into strand 21, twisted with the fingers mutually by many strands 21 and form the cable wire of well-known structure by steel wire strand.

The above-mentioned

stubborn collar

3,3 that connects is compiled the external peripheral zone that enrolls the protective wire 5 of rollback in insertion cable wire 2, simultaneously in this periphery of being compiled slotting part portion 4 for the fore-end 2a of crooked cable wire 2 and with its end, and coating is the synthetic resin R of usefulness fixedly.

Details are as follows to twist the production order that connects the

collar

3,3.

At first, shown in Fig. 2 (a), the front part 2a of cable wire 2 is bent to the U word shape, and the strand 21 of its end is twisted with the fingers part with specific length closing of cable wire 2 enroll simultaneously.

To cut off with instrument with pliers or cutting nippers etc. and cut off from the front part of the outstanding many strands 21 in the outside of the cable wire 2 that enrolls like this, with example is same in the past.

So this position forms large diameter sloping shape (with reference to figure 2 (b)) in ring-type one side.

Secondly, shown in Fig. 3 (a), in the part of the above-mentioned sloping shape of cable wire 2, on one side begin to another side, use the protective wire 5 that constitutes by hinge lines 51 to twine thick and fast from it.

At this, preferably hinge lines 51 is all inserted to be incorporated into the states in the cable wire 2 from each end that begins to reel top and reel terminal and become one.

Then, shown in Fig. 3 (b), apply synthetic resin R at protective wire 5 places.

This synthetic resin R, comprise the resin that is combined to rubber and allyl resin and additive and mixed solvent as styrene though can use, but so long as under liquid state good, the material (can follow cable wire 2 crooked or flexible degree) that after sclerosis, has certain flexibility of infiltration property, just do not have what qualification.

In addition, though the thickness of synthetic resin R is about 1mm, be preferably in the scope of 0.5mm to 1.5mm.

That is, when the thickness of synthetic resin R is lower than 0.5mm, its hiding power a little less than, as surpassing 1.5mm, then may damage its pliability, can hardening and waste resin.

And, as the synthetic resin R that will on protection silk 5, apply, for example during painted the use, can be easy to distinguish needed hoist cable 1, can increase work efficiency at building-site with the grade of expression hoist cable 1 etc.

Moreover; about on protective wire 5, applying the protective wire 5 of synthetic resin R and the infiltration of cable wire 2; it is the strand 21 that forms cable wire 2 with steel wire; do antirust processing with wet goods then; have material oil loving, for example organic solvent so long as comprise for such oil, infiltration property and tack will improve.

In addition, in the above-mentioned enforcement,, make end portion treatment after the both ends of the hinge lines 51 of protective wire 5 can certainly being twisted binding mutually though, be not limited thereto for the both ends of the hinge lines 51 of protective wire 5 are enrolled cable wire 2 and carried out end portion treatment.
