The driving mechanism in portion provides, and speed is at the uniform velocity adjustable.
The preheating system being made of during carriage walking components such as intermediate frequency power cabinet 2, transformer 6, load coils 8
System carries out continuous heating to load coil side channel shaped steel rail.
Fig. 2 shows load coil 8 is set on insulated mounting plate 13, wherein load coil 8 includes imitative slot
Silicon steel sheet 19 is arranged on the multi-loop copper tube 18 for the multi-loop copper tube 18 of type rail cambered surface.It is furnished with a large amount of silicon steel sheets on multi-loop copper tube 18
19 to reinforce induced magnetic field at cambered surface.19 place cambered surface of silicon steel sheet is to be used to heat the groove cambered surface of groove-shape rail, that is, slot
Shaped steel rail cover to be welded sets 20 (and in-site measurement rail most easily-worn positions), as shown in Fig. 3.
Cooling water nozzle 17 is arranged in 8 top of load coil, wherein cooling water nozzle 17 is multiple, the top of load coil 8
Two copper electrode plates 16 are arranged in portion, and insulation board is arranged between two copper electrode plates 16.
Equipped with a large amount of silicon steel sheets 19 to reinforce induced magnetic field at cambered surface on multi-loop copper tube 18.19 place cambered surface of silicon steel sheet is used
In the groove cambered surface of heating groove-shape rail, that is, groove-shape rail cover to be welded sets 20 (and in-site measurement rail is most easy to wear
Position), as shown in Fig. 3.
Induction coil guide clamping mechanism 7 includes walking steamboat 14, installation hinge 11, aluminium alloy frame 12, insulated mounting plate
13 and welding gun holding frame 9, wherein aluminium alloy frame 12 is arranged in 7 two sides of induction coil guide clamping mechanism, and insulated mounting plate 13 is arranged
In 7 middle part of induction coil guide clamping mechanism, 13 lower end of insulated mounting plate setting walking steamboat 14, wherein insulated mounting plate 13
Spring 21 is set between inside and aluminium alloy frame 12.
Walk steamboat 14 be it is multiple, walking 14 wheel face of steamboat be groove profile rail arc shape.
In Specific construction, small rail car is driven by driving motor, can be moved forward and backward along grooved track, forward speed
It can freely adjust between 0-8mm/s.Before carrying out preheating and soldering operation, need to see first by trolley along track travel a small distance
It examines and adjusts the clip position of welding gun and preheat coil and waited at a distance from supplement of an arc face with groove-shape rail.After adjustment, according to setting
Trolley forward or backward speed, set matched induction heating power output power (adjustable extent is in 0-80KW) and
Arc welding wire feed rate.After being all provided with, starting induction heating power and small rail car, induction coil will be begun to warm up
Groove-shape rail, after a bit of time (about 20s, specific time change according to the speed of travel that trolley is set) of complete machine walking,
Start arc welder and carries out soldering operation.The effect for first opening heating power supply is that rail heating needs the time, through after a period of time
Afterwards, subsequent position to be welded can reach expected preheating temperature, and the quality of soldering operation can just be guaranteed.Pass through above-mentioned step
Suddenly, so that it may realize continuously pre-heating and the soldering operation that long range is carried out to groove-shape rail.
During carriage walking, pre-heating system first heats groove-shape rail groove cambered surface, when trolley continues to move to, welding gun
Holding frame 9 and the electric torch being mounted thereon, which will be moved to, have been had at the groove-shape rail of certain temperature, is opened by soldering system
Beginning weld job.During trolley is advanced, along the axial direction of load coil side channel shaped steel rail, complete machine will continue
Progress first preheat, the operation process of rear soldering finally obtains a long weld seam along rail axial direction.
Before preheating and soldering operation, needs to treat and be polished before soldering groove-shape rail carries out except dust, crackle etc.；Making
After the completion of industry, polishing guarantees the shape of rail after needing to carry out soldering position.In addition, when equipment completes one section of groove-shape rail
After preheating is with soldering operation, when operation if you need to carry out another station track, it is only necessary to whole set equipment direction be rotated 180 degree, then instead
To walking dolly.
It as shown in Figures 4 and 5, is the stabilization for guaranteeing preheating with the position of soldering, the left and right shake up and down not with carriage walking,
Devise welding gun and induction coil guide clamping mechanism 7.Walking steamboat 14 is designed as groove profile rail arc shape, and pacifies in its side
There is spring 21 to provide certain side-thrust, guarantees that horizontal direction is fitted closely with rail when its walking.In addition by entire welding gun and
The self weight of induction coil guide clamping mechanism 7 guarantees that vertical direction is fitted closely with rail when walking steamboat 14 is walked.
Two walking steamboats 14, welding gun holding frame 9 and load coil 8 are fixed on insulated mounting plate 13, with track
There is certain freedom degree in 5 level of trolley and up and down direction.When there is slight shake in small rail car 5, steamboat 14 of walking
Welding gun holding frame 9 and load coil 8 will be driven to carry out self-control on the basis of the groove cambered surface of groove-shape rail, guaranteed
The stability of preheating and soldering position.
In entire operation process, induction coil and water cooled welding torch are fixed on track by matched guide clamping mechanism
The side of trolley, the two standoff distance are adjustable.But under same process conditions, the spacing of the two will immobilize.In addition,
Guide clamping mechanism relies on its directive wheel and spring during carriage walking, come guarantee in operation process welding gun and heating coil with
Groove-shape rail position to be welded it is relatively fixed.
The utility model has the advantage of pre- due to carrying out groove-shape rail rail head by the way of Medium frequency induction electric preheating
Heat, in the case where technological parameter is the same, the heating temperature to soldering position is highly stable, and multiplicity is high.For the resurfacing of rail
It repairs, the height of preheating temperature directly affects the success or failure of Repair Welding.It therefore, can greatly in such a way that electric induction preheats
Improve the quality of resurfacing of rail reparation.For groove-shape rail soldering, track defect type is mainly track small curve radius
The rail head side grinding at position, it is disposably long to soldering position.Therefore in orbit by carriage walking, the preheating of disposable long range
Groove-shape rail, operating efficiency are much higher than traditional preheating method.
By the design of welding gun and induction coil guide clamping mechanism, welding gun and sense in track carriage walking ensure that
Answer heating coil that can stablize preheating and the fixed cambered surface of soldering groove-shape rail.
Finally it should be noted that above embodiments are only to describe the technical solution of the utility model rather than to this technology
Method is limited, and the utility model can above extend to other modifications, variation, application and embodiment in application, and because
This thinks all such modification, variation, application, embodiments all within the scope of the spirit or teaching of the utility model.
