At present, excavator is widely used in departments such as mine, water conservancy as a kind of large-scale Work machine, and the guy wire device is a vitals of excavator, and its performance and quality are directly connected to the work safety and the manufacturing efficiency of excavator.Excavator is in the past continued to use old-fashioned guy wire structure (wrap style) always, promptly adopts steel cable to pass through 3 pulleys and back and forth twines the movable guy wire structure of forming 4 balances.Because the excavator guy wire is an easily worn part, need often to change, easy in order to install, to change, Taiyuan Heavy Machinery Plant has improved the coupling arrangement of guy wire and shear leg, (see too heavy factory manufacturer's standard: TZB7364-94), it is made of with the noose that the alloy pouring connects wire rope and two ends with fixed guy wire structure to have designed excavator.Owing to adopt 4 fixed guy wires to replace the wrap style guy wire, can independent installing/dismounting, it is simple and convenient therefore to construct, and liked by the user.This fixed guy wire is widely adopted though have above advantage, the shortcoming that working life is short, and the user is still puzzling.How to improve the working life of fixed guy wire, become related domain technical problem anxious to be solved.
In order to improve the working life of fixed guy wire, CN2336008Y also discloses a kind of " Cable stretching for electric shovel device ", and its device is just selected its wire rope for use intensity higher ' locked coil wire rope ' basically with above-mentioned structure.Because under the situation of same diameter, the minimum breaking force summation of locked coil wire rope is more much bigger than the minimum breaking force summation of ordinary steel rope, obviously can prolong the working life of guy wire, still this design is as the effect of low load with strong power, and neither science is very uneconomical again.Because than expensive many of ordinary steel rope price, therefore strengthened product cost with the locked coil wire rope of diameter.
The casting of metals consolidation method of wire rope and socket, traditional process step comprises: tie up fag end, blanking → fag end broken lot → cleaning brush → brush location → socket preheating → pouring alloy → cooling, cleaning.Because wherein: adopt acid, basic solvent degreasing, light as cleaning brush is first; Pouring alloy aspect often adopts the higher zinc base alloy of fusing point, and this technology can influence the performance of steel wire, is the major reason that causes the easy fracture of wire of wire rope and socket tail end connection place.Therefore, traditional wire rope and the metal of socket pouring consolidation method also is one of the reason in the fixed guy wire of influence working life.
Summary of the invention:
The objective of the invention is to overcome the shortcoming of background technique, a kind of excavator guy wire is provided, not only install, change easy, and have long service life, advantage that product cost is low.
Another object of the present invention provides the manufacture method of a kind of excavator with guy wire, overcomes the shortcoming of tratitional technology, the working life of guaranteeing ' guy wire '.
Above-mentioned purpose of the present invention is achieved in that a kind of excavator guy wire, is made of with the socket that the metal pouring connects wire rope and two ends, it is characterized in that the connection place of described wire rope and socket tail end is provided with anti-tired pipe box.
Described anti-tired pipe box is with plasticity good metal material, preferably selects the low carbon steel seamless steel pipe for use.
A kind of excavator manufacture method of guy wire, its process step is:
(1) fag end of tie wire rope and length blanking on request;
(2) the fag end broken lot is the inverted cone brush;
(3) with ultrasonic cleaning brush steel wire;
(4) on wire rope, be positioned at the anti-tired pipe box of root compacting of brush;
(5) brush is placed socket inner chamber and location;
(6) socket preheating;
(7) socket inner chamber pouring alloy;
(8) cooling, cleaning.
Described on wire rope, tired pipe box is prevented in the root compacting that is positioned at brush, is to prevent that earlier tired pipe box is contained on the wire rope, and is positioned at the root position that connects with socket, uses the specialized mould gentle pressure to steel pipe and the void-free degree of wire rope then.
Described pouring alloy is a lead-base bearing alloy.
The pouring temperature of described pouring alloy is 330-380 ℃.
Described noose preheating temperature is 250-300 ℃.
The present invention compared with prior art has the following advantages and good effect.
Analyze the reason of the excavator of prior art with guy wire weak point in working life, mainly be because excavator often is in complicated applying working condition, it upgrades weighing arm ' guy wire ', bearing huge reciprocal impulsive load, the connection place of wire rope and socket tail end particularly, be concentrated, the most dangerous position of fatigue stress, in actual the use, guy wire destroys, the place of disconnected thigh almost all occurs in this position that wire rope connects with the socket tail end.Therefore, improving the fixed guy wire key in working life, is the fatigue resistance that how to increase wire rope and socket tail end connection place, rather than substitutes low intensive wire rope with the wire rope of high strength grade simply.Because the present invention has caught this principal contradiction, is provided with a kind of anti-tired pipe box in the connection place of wire rope and socket tail end, and provide the manufacturing process that realizes being provided with anti-tired pipe box.Therefore, the present invention not only makes ' guy wire ' to prolong working life, and available ordinary steel rope can satisfy usage requirement, has reduced the cost of ' guy wire '.
The process step of the casting of metals consolidation method of traditional wire rope and socket comprises: tie up fag end, blanking → fag end broken lot → cleaning brush → brush location → socket preheating → pouring alloy → cooling, cleaning.Wherein cleaning brush adopts the degreasing of basic solvent elder generation as first, and is with the preserved material light that contains hydrochloric acid, zinc-plated more then.This technology is not only complicated, and steel wire is subjected to the corrosion of acid, aqueous slkali, can reduce tensile strength, and this also is the major reason that causes the easy fracture of wire of wire rope and socket tail end connection place.The present invention has eliminated this technology, adopts custom-designed ultrasonic cleaning equipment and technology to clean, and has both simplified operation, has guaranteed cleaning quality, does not have acid and alkali corrosion again, thereby has improved the fatigue resistance of wire rope and socket tail end connection place.Owing to simplified technology, also reduced the cost of product.In addition, traditional consolidation technique is often adopting zinc base alloy aspect the pouring alloy, because the fusing point of zinc is higher, higher pouring temperature (460 ℃) can influence the performance of binding site steel wire, and this also is that the final fracture position of excavator guy wire often occurs in one of reason of socket root.Pouring alloy of the present invention adopts lead-base bearing alloy, and the pouring temperature is lower, and the noose preheating temperature is controlled at 250-300 ℃ of scope.Low than the tratitional technology temperature, can prevent the wire rope too high reduction intensity of being heated, thus the working life of having improved ' guy wire '.
