Abstract
The present invention relates to a kind of method and apparatus of railway track bond wire welding, its concrete grammar is with behind explosive, dispersant, raising agent and the blast stabilizing agent mixing, is contained in the special nonmetal medicine box, and welding medicine dose is 15-30 grams.With adhesive sticker special bonding pad, medicine box are attached to the position that needs welding, insert detonator, ignite the back bonding pad securely with rail welding together.Its advantage is that construction technology is simple, the efficiency of construction height, and weld strength is good, not influenced by execution conditions, and used blasting explosive secure performance is good, and except that with the cap sensitive, general impact, flame etc. all can not make explosive charge and burning.
Description
The present invention relates to a kind of method and apparatus of railway track bond wire welding.
The method of attachment of railway track bond wire at present has plug pin method, ditch nail method, electric welding method and from several different methods such as fusing process of intermediates, but the problem that these methods exist is more: plug pin method and ditch nail method construction more complicated, phenomenon such as corrosion, dry joint happens occasionally, vibrations rail during train running, can cause disconnected glue, plug pin to come off, by the people destroy, loss accident is also more.The electric welding method can't be used in the place that there is not electricity away from the station, thereby is very limited.Though from molten method certain superiority is arranged, the medicinal powder moisture-sensitive is difficult to light after making moist, and special die life is short, and a mold can only use 300 times, and the welding distance is less than 2 kilometers, and cost is higher.Weld strength is not high simultaneously, vertically knocks solder joint with the iron hammer about half pound, and it is come off.In order to overcome above-mentioned weak point, the present invention utilizes the metallic explosive welding method to make two kinds of metallic interior surface produce jet, thereby makes two kinds of metals form metallurgical binding, selects for use explosion welding method to replace traditional method of attachment.
The purpose of this invention is to provide the rail wiring explosion welding technique that a kind of method is more easy, connection is more firm, service time is longer.
Purpose of the present invention realizes by following concrete measure:
Fig. 1 is the structural representation of medicine box
Fig. 2 is the structural representation of bonding pad
The used welding medicine dose of each solder joint is the 15-30 gram during rail bond welding, is made up of explosive, dispersant, raising agent and blast stabilizing agent, and its composition and percentage by weight are as follows:
Explosive: Nitrates explosive 80-100%
Dispersant: acid dyes, as pinkish red (tonyred) 0-5%
Raising agent: anion surfactant, as benzene sulfonamide acids 0-5%
Blast stabilizing agent: hexogen, too peace, HMX or TNT 0-20%
With reference to Fig. 1, the welding medicine that the rail bond explosive welding is used is contained in the special medicine box, medicine box (1) is made by nonmetallic materials, wall thickness 0.05-0.20 centimetre, the long 2.00-6.00 of box centimetre, wide 1.50-3.00 centimetre, high 1.50-4.00 centimetre, there is a semi-circular groove (2) in medicine box (1) bottom surface central authorities, and radius is 0.30-0.35 centimetre.One detonator hole (4) is arranged on the lid that other does (3), and diameter is 0.70-0.85 centimetre.
With reference to Fig. 2, long 2.00-6.00 centimetre of the bonding pad (5) that becomes with cold-rolling steel-plate punch, wide 1.50-3.00 centimetre, thick 0.50-3.00 centimetre, there is a semicircle tongue (6) at bonding pad (5) middle part, the radius of groove is 0.30-0.35 centimetre, bonding pad (5) one ends two jiaos (7) have a downwarp, with the plane included angle be 0-20 °.
In will packing medicine box (1) into by weight the welding medicine 15-30 gram that regulation mixes, the detonator hole (4) on the medicine box lid (3) touch with adhesive tape shuts.Lead is φ 6-7 millimeter fine aluminium or aluminium alloy wire, multiply, long 20-80 centimetre, bent intermediate.Detonator is No. 8 electric caps or on-electric detonator.
Further illustrate with regard to specific embodiment below:
Embodiment one:
20 grams of packing in the medicine box weld medicines, and its component is:
Nitrates explosive 16 grams
Pinkish red 1 gram
Benzene sulfonamide acids 1 gram
Embodiment two:
30 grams of packing in the medicine box weld medicines, and its component is:
Nitrates explosive 27 grams
Pinkish red 0.9 gram
Benzene sulfonamide acids 0.9 gram
TNT 1.2 grams
Execute-in-place method: the burning skin is deoiled, derusts, goes in the polishing of rail welding position, use pressure sensitive adhesive at the position of polishing together with bonding pad the medicine box that installs the welding medicine, in the detonator hole, ignite beyond the people retreats to 15 meters on the detonator insertion medicine box.After the ignition, bonding pad and rail are welded together, coat antirust paint after bonding pad is cleaned.
The present invention compared with prior art has the following advantages:
1, the present invention adopts batch production production with material therefor, thereby construction technology is simple, only needs that medicine box, bonding pad, lead are sticked on rail and gives the position, bonding part and ignite and can finish welding, has greatly alleviated workpeople's labour intensity.
2, efficiency of construction height, a solder joint can weld less than one minute.
3, weld strength height after the welding, could shovel solder joint get off with flat chisel. Long service life, because rail and bonding pad are metallurgical binding, but never drop-off.
4, no matter not affected by execution conditions, be blowing and raining, and the severe cold burning sun all can be constructed, and also can at any time construct in the place that does not have power supply away from the station.
5, the bond wire accident to occurring can in time be repaired such as loosening, plug pin comes off etc., and is fast and reliable.
6, because batch production production has the unified specification standard, therefore can guarantee welding quality.
7, can improve electric conductivity, economical with materials reduces cost.
8, used blasting explosive secure performance is good, can only use cap sensitive, and other general impact, friction, flame, even riflery all can not make explosive charge and burning.
