Abstract
The invention provides an anchor rope device of a large mining excavator and a manufacturing method for the anchor rope device, and relates to the large mining excavator. The technical problems that an existing anchor rope device is not reasonable in structure, the manufacturing difficulty is increased due to pressing of an anti-fatigue pipe sleeve, and the service life of an anchor rope is shortened due to lack of anchor rope pre-stretching are solved. A level-A galvanized steel wire rope meeting the ASTM-586 standard is adopted by the anchor rope device, a sealing bushing is arranged at the tail end of a socket cone, and an anti-loosening check block is arranged in an inner cavity of the socket cone. The manufacturing process for the anchor rope device comprises the steps of (1) bundling rope ends of the steel wire ropes and carrying out blanking according to required lengths, (2) loosening strands of the rope ends to form inverse-cone-shaped brush heads, (3) cleaning brush head steel wires, (4) placing the brush heads into the inner cavities of sockets and locating the brush heads, (5) preheating the sockets, (6) pouring metal into the inner cavities of the sockets, (7) carrying out cooling and cleaning, and (8) pre-stretching an anchor rope. The process steps are simplified, the manufacturing cost is lowered, and the service life of the anchor rope is prolonged.
Description
Technical field
The present invention relates to large-sized mining dredger, particularly large-sized mining dredger is used for lifting a kind of guy wire device of boom and manufacture method thereof.
Technical background
The guy wire device of large-sized mining dredger is used for lifting the vitals of boom, and its workmanship is directly connected to work safety and the production efficiency of excavator.
CN1542309A discloses a kind of pulling rope for digging machine, and water by wire rope and two ends metal the socket connected and form, the connection place of described wire rope and socket tail end arranges anti-tired pipe box.Meanwhile, disclose a kind of manufacture method of pulling rope for digging machine, its processing step is: the fag end also length blanking on request of binding steel wire rope; Fag end broken lot is back taper brush; With Ultrasonic Cleaning brush steel wire; On a steel cord, the anti-tired pipe box of root compacting of brush is positioned at; Brush be placed in socket inner chamber and locate; Socket preheating; Socket inner chamber pouring alloy; Cooling, cleaning.
The stretching rope for excavator of prior art, owing to adopting ordinary steel rope, in order to improve the application life of guy wire, is therefore provided with anti-tired pipe box in the connection place of wire rope and socket tail end.Like this, not only add manufacturing cost, and the operation of compacting pipe box extremely bothers; Because socket end construction is unreasonable, high temperature capping metal liquid easily flows into Gang Si Sheng Sew gap, reduces the Strong degree of steel wire, affects the application life of guy wire.
The stretching rope for excavator manufacture method of prior art, owing to being included in the anti-tired pipe box step of root compacting of wire rope brush, adds manufacture difficulty; Owing to lacking guy wire pre-stretching step, in use four guy wires because of unbalance stress, can cause the too early fracture of wire of wire rope, reduce the application life of guy wire.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, a kind of large-sized mining dredger guy wire device is provided, solve the irrational technical problem of existing guy wire apparatus structure.
Another object of the present invention is to provide a kind of large-sized mining dredger guy wire manufacture method, solves the anti-tired pipe box of existing compacting and adds manufacture difficulty, lack the technical problem that guy wire prestretched reduces guy wire application life.
The present invention is achieved through the following technical solutions:
A kind of large-sized mining dredger guy wire device, comprise: wire rope, water the socket connected with metal at wire rope two ends, the bearing pin be connected with socket, be arranged on the packing ring between socket and bearing pin, and the cottor pin of bearing pin, it is characterized in that: described wire rope adopts the A level galvanized steel wire rope of ASTM-586 standard, and steel cord structure is steel core 1 × 233; It is bushing that described socket cone tail end arranges sealing, and the cone cavity of described socket is provided with anti-loosening link stopper.
A kind of large-sized mining dredger guy wire manufacture method, its processing step is:
1. the fag end also length blanking on request of binding steel wire rope;
2. fag end broken lot is back taper brush;
3. brush steel wire is cleaned;
4. brush be placed in socket inner chamber and locate;
5. socket preheating;
6. socket inner chamber capping metal;
7. cool, clear up;
8. guy wire prestretched.
Further, the preheat temperature of step 5. described socket is 220-280 DEG C.
Further, step 6. described capping metal be pure zinc.
Further, the pouring temperature of described pure zinc is 320-360 DEG C.
Further, the described step load that 8. guy wire prestretched is born is 40% of wire rope rupture strength.
Further, 3. described step cleans brush steel wire, adopts Ultrasonic Cleaning or adopts high temperature and high pressure steam cleaning.
Compared with prior art, because guy wire device adopts the galvanized steel wire rope of strand structure, wire rope good rigidly, need not arrange anti-tired pipe box at wire rope and socket tail end, simplify processing step, reduced manufacturing cost in the present invention; Due to socket cone tail end, to be provided with sealing bushing, prevents high temperature metal liquid from flowing into Gang Si Sheng Sew gap, can not reduce the Strong degree of steel wire, improve the application life of guy wire; Because the cone cavity of socket is provided with link stopper, prevent wire rope from outwards loosening along tapered sleeve, improve the safety that guy wire uses; Because manufacture method adds guy wire pre-stretching step, ensure that in use four guy wire uniform force, the too early fracture of wire of wire rope can not be caused, improve the application life of guy wire; Because capping metal adopts pure zinc without lead-base bearing alloy, substantially increase with steel wire in conjunction with Strong degree; Due under the prerequisite ensureing metal fluidity, reduce the preheat temperature of socket, effectively can prevent steel wire overheated reduction Strong degree.
Adopt the large-sized mining dredger guy wire device that the present invention manufactures, after mine uses, the guy wire life-span significantly improves, and the stage of replacement is by originally bringing up to 3 years less than 2 years.
