Fig. 2 is flash welder schematic diagram.
Embodiment
Below in conjunction with the accompanying drawings with specific embodiment to a kind of fixed flash welding of track flat car provided by the utility model
Machine equipment is described in detail.
Fig. 1 and Fig. 2 show that the front end of the first one steel rail 2 is passed through equipped with symmetrical flash welder 3 with certain speed by right to left
Flat car 1, the regulation of horizontal direction is carried out to rail by entering track to track device 11, subsequently into the first rail locating rack 12, the
One rail locating rack 12 treats welding steel rail 2 and carries out Primary Location, and rail 2 is entered by the moving frame 31 and quiet frame 32 of flash welder 3
Second rail locating rack 14, rail 2 pass through the support of hydraulic station 13, and go out track to track device 15, right by going out track to track device 15
Middle regulation rail 2 simultaneously enters decelerator 16, treats that the rear end of the first one steel rail 2 enters the quiet frame 32 of flash welder 3, decelerator 16 passes through
The speed of rail 2 is reduced to zero by the start ratio wheel 18 of oil cylinder 17.The quiet lower end of frame rail clamping cylinder 33 connects transformer 34, in transformation
The lower end connection electrode 35 of device 34, by the clamping cylinder 33 installed in the quiet upper end of frame 32 and electrode 35 by the front end of the first one steel rail 2
Vertical orientations are fixed.Quiet one side of frame 32 is provided with the first quiet 36 and second quiet frame oil cylinder 37 of frame oil cylinder of horizontal direction, and first is quiet
The quiet front end of frame oil cylinder 37 of frame oil cylinder 36 and second is provided with the first quiet 38 and second quiet frame strut 39 of frame strut, the first quiet frame oil cylinder
36 can carry out the motion of horizontal direction with the quiet frame strut 38 of start first, and the second quiet frame oil cylinder 37 can also the support of the second quiet frame of start
Bar 39 carries out the motion of horizontal direction.First quiet 36 and second quiet frame oil cylinder 37 of frame oil cylinder is supportted by the first coupled quiet frame
38 and second quiet frame strut 39 of bar is fixed to the front end level orientation of the first one steel rail 2.
Second one steel rail front end after entering the regulation of the horizontal direction of track to track device 11 into the first rail from right to left by determining
Position frame 12, the first rail locating rack 12 carry out primary contraposition regulation to the second one steel rail front end, and the second one steel rail front end, which enters, to be dodged
The moving frame 31 of welding machine 3, in relaxed state.
Drive the rack 22 on welding machine gear 20 and slide rail 21 to engage by the hydraulic motor 19 of flash welder bottom, drive
Flash welder 3 carries out the primary of level orientation to flash welder 3 along slide rail 21 and adjusted, by entering the rail of track to track device 11 and first
Locating rack 12 carries out the sub-adjusting of level orientation to the second one steel rail.
The top and bottom of 3 moving frame of flash welder 31 are separately installed with the clamping cylinder 40 and 41 of vertical direction, clamping cylinder
40th, 41 are connected with upper/lower electrode 42,43 respectively, and clamping cylinder 40,41 realizes second by making the up and down motion of moving electrode 42,43
The centering of rail and the first one steel rail vertical orientations.The right and left of moving frame 31 is separately installed with oil cylinder 44 and strut 45, by dynamic
The oil cylinder 44 for the level orientation that frame is left and right symmetrically arranged and strut 45 thereon can realize the second one steel rail and the first one steel rail
The centering of level orientation.
After centering regulates, flash welder 3 is powered, and the moving frame 31 for clamping rail gradually moves axially adjacent to towards quiet frame 32,
And gradually make moving frame end rail and the mutually micro- pick-up current of quiet frame end rail by and form flash of light, by glistening and heating rail
End face heat penetration increase, moving frame 31 is close progressively to be accelerated, and rail burns aggravation, is burnt latter stage in rail flash, and moving frame 31 is leaned on
Closely speed increasing, two one steel rail end contacts and extruding form weld seam.After the displacement and pressure for reaching requirement, upset terminates.
Now in moving frame end and quiet frame end still in clamped condition, the start of upset oil cylinder 46 in moving frame 31 pushes away convex the rail of welding fabrication
Knife 47, which is axially moved, turns down the overlap at welding point position, completes whole rail flash welding overall process.
The flash welder that flat car opposite side is symmetrically installed can be done in the same fashion rail centering regulation simultaneously.Steel
After the completion of rail centering, side welding machine can be started rail is welded, other side is complete after the completion of the rail welding of side
Rail in pairs is welded.
Two fixed flash welders being symmetrically installed can share a set of electric power system, hydraulic pressure and cooling system, power supply, liquid
Pressure and cooling system.The rail of left and right station track can be sent into simultaneously for the flash welder being symmetrically installed and centering is adjusted, and one
Side is welded in advance, and opposite side can start welding at once after the completion of welding, saves the engineering construction time.
The utility model can realize the strand road of railway two while carry out changing paving operation, mechanization degree height, efficiency of construction
It hurry up, old rail can be put away while laying new rail, change after the completion of paving operation and deposit in curb without rail, will not be to both wired
Traffic safety causes a hidden trouble.Improve the security runed during railway maintenance.
Finally it should be noted that above example is only describing 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, change, application and embodiment in application, and because
This thinks all such modification, change, application, embodiments all in the range of spirit or teaching of the present utility model.
