Because in recent years, along with railway to high-speed development, constantly pursue the stability of train driving, the reduction of rail seam crossing noise, the indexs such as reduction of track maintenance expense, thereby use a kind of to be length that 25 meters standard-sized track welds, to be lengthened to the long track of welding of 1.0 kilometers～1.5 kilometers degree.
Often use flash butt welding, pressure-gas weld, pressure shaping arc welding or exothermic welding in the welding procedure of track.Flash butt welding can be welded track expeditiously in unusual short time, can obtain the high welded joint of reliability simultaneously.
The flash butt welding of track is that big electric current is added on two clamped tracks of end, contact repeatedly with spark on one side and splash, heated contact surface sharply adds upward pressure when reaching proper temperature on one side, makes the method for track crimping by upset bull welding (flash butt welding).
On the other hand, track is to make under certain size acceptable tolerance, for example the height of track have+1.0mm～-acceptable tolerance of 0.5mm, for example track of heavy 60kg, the width of head has+0.8mm～-the size acceptable tolerance of 0.5mm, the therefore size and dimension of every track some deviation all.When the such track of welding, for the stability of train driving with prevent noise etc., must carry out correct centering to the upper surface of the both sides track head at junction surface and the side of interior trackside.
For this reason, former method is after the head upper surface contraposition of 2 tracks that will engage, and with the clamp jaw that is arranged on the clamping device on fixing head and the movable head belly both sides of each root track is clamped.When clamping the belly both sides of each root track, the pad of adjusting usefulness is inserted between track belly and the clamp jaw, make the side contraposition of the interior trackside of 2 track heads then, for example the Japanese patent gazette spy opens the such of clear 63-238984 number record, change the track belly about one of the Position of Hydraulic Cylinder of clamping head of side, after the side contraposition of trackside track is clamped in making.
Like this, shown in the front view of the flash butt welding device of Figure 10, when track is clamped, for the left and right sides track that will engage is positively clamped, on fixing head 12 and movable head 13, two stack clamping devices 2 are set respectively, respectively the belly of the track 1 about two positions clamp.Then, be added on the track 1 from the big electric current of electrode handle that is separately positioned on fixing head 12 and the movable head 13 on one side, the track 1 that is clamping is moved to fixing head 12 sides on one side on movable head 13, on the composition surface, contact repeatedly and splash with spark, the heating composition surface is crimped on track together.
As mentioned above, the side contraposition of trackside in the track head that will engage the time, or the pad of usefulness is adjusted in use, or change the position of hydraulic cylinder of the clamping head of a side, at this moment just must be repeatedly for adding the pad of adjusting usefulness, or the position of mobile hydraulic cylinder repeatedly, just difficult the correct centering of track that will engage, therefore the problem that spend the more activity duration is arranged.
Though method in the past is under the state that track is clamped, carry out the centering contraposition by steadily moving, absorb the tolerance of track whereby, make the structure of device become complicated in this case, the problem that whole device size is strengthened is arranged.
And, flash butt welding device in the past is in order to clamp the left and right sides track that will engage really, on fixing head and movable head, independently 2 stack clamping devices are set respectively, the mechanism that changes the Position of Hydraulic Cylinder of a side in order to carry out the track contraposition is set on each clamping device again, except clamping device, also be provided with electric current is added to electrode on the machine, therefore become complicated with regard to the structure that makes fixing head and movable head, make the size of fixing head and movable head become big, the minimum weight of welder body just reaches 20 tons.Though thereby can use in factory, be difficult to be transported to and lay the track scene and used.

Shown in the sectional drawing that Fig. 1 represents clamping device structure of the present invention, the clamping device 2 that clamps the belly of track 1 has the belly of clamping track 1 and the 1st clamping head 3 and the 2nd clamping head 4 that are oppositely arranged.The 1st clamping head 3 is provided with energising clamp jaw 5a and hydraulic cylinder 6a, and the 2nd clamping head 4 also is provided with energising clamp jaw 5b and hydraulic cylinder 6b.Energising clamp jaw 5a, 5b have the clamp jaw 7 that clamps track 1 and electric current are added to electrode block 8 on the track 1.Clamp jaw 7 is being provided with the guidance part 72 of concavity at the central part of the leading section 71 that has the triangle groove shown in the front view of the sectional drawing of Fig. 2 and Fig. 3, rearward end is fixed on respectively on the leading section of piston rod 61 of hydraulic cylinder 6a, 6b.Electrode block 8 is inserted in 72 li of the guidance parts of clamp jaw 7, and the end is by many groups dish spring, for example be installed on the clamp jaw 7 by 4 groups of dish springs 9 thereafter.The leading section of this electrode block 8 is more outstanding a little than the leading section 71 of clamp jaw 7.
The cylinder diameter of the hydraulic cylinder 6a of the 1st clamping head 3 is made bigger than the cylinder diameter of the hydraulic cylinder 6b of the 2nd clamping head 4, thereby the thrust of the hydraulic cylinder 6a of the 1st clamping head 3 is just than the thrust of the hydraulic cylinder 6b of the 2nd clamping head 4 approximately greatly for example about 20%.
On the hydraulic cylinder 6a of the 1st clamping head 3, be provided with journey variable parts 10.Journey variable parts 10 are arranged on the rear side of the piston 62 of hydraulic cylinder 6a, and threaded portion 65 that is arranged on piston rod 64 top ends that run through hydraulic cylinder end cap 63 and the nut 66 that is screwed on this threaded portion 65 are arranged.Shown in the front view of Fig. 4, the scale of cutting apart by equal angles is arranged on the surface of nut 66, the marking plate 67 that is installed on the hydraulic cylinder end cap 63 is arranged around nut 66.
Fig. 5 is to use the front view of the flash butt welding device 11 of the clamping device 2 with said structure.As shown in the figure, flash butt welding device 11 has fixing head 12 and the movable head 13 and the configuration portion 14 of the gate-type made.On fixing head 12 and movable head 13, clamping device 2 is being set respectively.Fixing head 12 and operating portion 14 are by along a plurality of guidance axis of the length direction setting of the track 1 that will engage, for example linked by 4 guidance axis 15.Movable head 13 can be bearing on the guidance axis 15 of 14 in fixing head 12 and configuration portion with being free to slide.And movable head 13 can move along guidance axis 15 by the hydraulic cylinder 16 that is installed on the operating portion 14.
Fixing head 12 and movable head 13 and operating portion 14 are formed by the extrasuper-duralmin of the very little Al-Zn alloy of magnetic density.
Like this, because being set respectively, clamp jaw 7 that a handlebar track 1 clamps and electric current be added to the integrally formed energising clamp jaw 5a of electrode block 8 on the track 1, the clamping device 2 of 5b on fixing head 12 and movable head 13, thereby can make simplifying the structure of fixing head 12 and movable head 13, can make fixing head 12 and movable head 13 miniaturizations.By fixing head 12 and the movable head 13 that forms this miniaturization with extrasuper-duralmin, just can alleviate the weight of fixing head 12 and movable head 13 significantly.
At the central part of the door shape of this fixing head 12 and movable head 13, shown in the sectional drawing of Fig. 1, make in advance the head upper surface position of determining track 1 benchmark leveller 17 above-below direction position consistency and fix.
Be provided with on the operating portion 14 have with figure on do not have the drive control part 22 of the members such as magnetic valve that the hydraulic package of expression is connected, by the side central part of operating portion 14 1 sides slippage detector 23 is installed at the lateral surface central authorities of fixing head 12 and movable head 13.Shown in the sectional side view of facing sectional drawing and Fig. 9 of Fig. 8, the movable part 26 that slippage detector 23 has rotary type potential difference meter 25, be connected with the gyroaxis of potential difference meter 25, the spring 30 by a plurality of recurrence usefulness of bearing 27 on movable piece 29 that is keeping with the gyroaxis vertical direction break-through of movable part 26 and by compression spring 28 and the gyroaxis that is installed in movable part 26.The mobile volume detector 24 of linear pattern potential difference meter also is installed between movable head 13 and operating portion 14 in addition.
The following describes the action when using flash butt welding device 11 to engage tracks 1 with said structure.
At first, two tracks 1 that end face is contacted gently are configured on the central part of the flash butt welding device 11 of making a type, and the junction surface is positioned on the central part of 13 on fixing head 12 and movable head.Then, two tracks 1 are risen, the head upper surface of track 1 are overlayed on the benchmark leveller 17 of fixing head 12 and movable head 13 with lowering or hoisting gear (among the figure do not have expression), make to engage about the head upper surface location of two tracks 1.Under this state, be separately positioned on the 1st clamping head 3 of the clamping device 2 on fixing head 12 and the movable head 13 and each hydraulic cylinder 6a, the 6b of the 2nd clamping head 4 activating the oil supply, piston 62 is advanced, clamp jaw 7 with the energising clamp jaw 5b of the clamp jaw 7 of the energising clamp jaw 5a of the 1st clamping head 3 and the 2nd clamping head 4 is clamped the belly side of track 1, thus track 1 is clamped.When clamping this track 1, because of clamping and clamp recess being arranged on leading section 71 on two positions and be divided into each tracks 1 that two-part jaw 7 handles in the left and right sides will engage, thereby energy clamp track 1 infalliblely.
When clamping track 1 like this, owing to the cylinder diameter of the hydraulic cylinder 6a of the 1st clamping head 3 is made bigger than the cylinder diameter of the hydraulic cylinder 6b of the 2nd clamping head 4, the thrust of the hydraulic cylinder 6a of the 1st clamping head 3 is bigger than the thrust of the hydraulic cylinder 6b of the 2nd clamping head 4, thereby making the hydraulic cylinder 6a of the 1st clamping head 3 advance to range, the front end face 71 of the clamp jaw of being installed on the hydraulic cylinder 6a with the 1st clamping head 37 determines to make the reference position of the location, belly side of track 1.
In addition, on the belly side that the energising clamp jaw 5b of the energising clamp jaw 5a of the 1st clamping head 3 and the 2nd clamping head 4 is overlayed at track 1 time, because the electrode block 8 that is installed on each clamp jaw 7 is more outstanding than the front end of clamp jaw 7 because of its front end, and be installed on the clamp jaw 7 by dish spring 9, thereby when the front end that makes electrode block 8 overlays on the belly side at track 1, can make electrode block 8 be docile and obedient the abdominal surface of track 1 and be adjacent to.Therefore, even there are the deviation that is caused by the size admissible error in the shape of the track 1 that will engage, size aspect, still can be crimped on the entire front end face of electrode block 8 reliably on the abdominal surface of track 1.Again owing to when overlaying electrode block 8 on the belly of track 1, be the outstanding that part of compact disc spring 9 of ratio clamp jaw 7 front ends of electrode block 8 front ends, thereby can with sufficient pressure electrode block 8 be crimped on the abdominal surface of track 1 by the elastic force of dish spring 9.Therefore, the contact resistance between electrode block 8 and the track 1 is reduced.
Like this, after 2 two tracks that will engage of clamping device, 1 clamping with fixing head 12 and movable head 13, whether the head side of the interior trackside of two tracks 1 of affirmation is consistent.There is when departing from the head side that shows the interior trackside of two tracks 1 in this affirmation result, hydraulic cylinder 6a, the 6b of the 1st clamping head 3 and the 2nd clamping head 4 are retreated, according to bias, make nut 66 clockwise directions of the journey variable parts 10 on the 1st clamping head 3 that is arranged on fixing head 12 or movable head 13 or revolution counterclockwise, change the stroke of the hydraulic cylinder 6a of the 1st clamping head 3.After this, hydraulic cylinder 6a, 6b are advanced, track 1 is clamped, whether the head side of trackside is consistent in confirming.
As mentioned above, make nut 66 revolutions of journey variable parts 10, make the stroke of the hydraulic cylinder 6a of the 1st clamping head 3 obtain fine setting, thereby make the head align laterally of interior trackside of track 1 and contraposition, thus can be simply, correctly the track 1 that will engage is carried out centering and contraposition.
After two track 1 centerings are clamped, predetermined electric current is flow to by electrode block 8 on the track 1 between fixing head 12 and the movable head 13 from welding transformer 18, with the hydraulic cylinder 16 that is installed on the operating portion 14 movable head 13 is advanced, two tracks 1 are engaged.Though electric current when welding transformer 18 flows to track 1, the conductor that connects the energising usefulness of welding transformer 18 and electrode block 8 is that the inside by fixing head 12 and movable head 13 is provided with, but owing to form fixing head 12 and movable head 13 with the minimum Al-Zn alloy of magnetic density, thereby can reduce when welding by the electric current of the conductor that flows through energising usefulness eddy-current loss in fixing head 12 and movable 13 li generations of head, fixing head 12 and movable head 13 miniaturizations can not only be made, and welding transformer 18 miniaturizations can be made.
When welding, while owing to use mobile volume detector 24 detections to move it by the amount of movement of the track 1 of movable head 13 clampings, thereby can correctly control the amount of movement of movable head 13.Again owing to when upset welding, detect upset bull welding pressure with slippage detector 23 and whether on the track 1 that clamps respectively with fixing head 12 and movable head 13, produce slippage and slippage, thereby can judge automatically that whether suitable welding is.
After the welding of track 1 finishes, make the hydraulic cylinder 21 of flash removal portion 19 advance to track 1 one sides, and make movable head 13 advance to fixing head 12 1 sides, the overlap on the weld part is removed, thereby finished weld job.Because when removing the overlap of weld part, the bite 20 of flash removal portion 19 is divided into head bite 20a and belly bite 20b and bottom bite 20c, and part is arranged is repetition, thereby with once moving the overlap just can remove weld part reliably.
Though the above embodiments are bigger than the cylinder diameter of the hydraulic cylinder 6b of the 2nd clamping head 4 to the cylinder diameter of the hydraulic cylinder 6a of the 1st clamping head 3 is made, the thrust of the hydraulic cylinder 6a of the 1st clamping head 3 describes than the big situation of thrust of the hydraulic cylinder 6b of the 2nd clamping head 4, but use the hydraulic cylinder of identical cylinder diameter at the 1st clamping head 3 and the 2nd clamping head 4, the pressure ratio of the actuating oil in the hydraulic cylinder that is fed to the 1st clamping head 3 is fed under the big situation of the pressure of the actuating oil in the hydraulic cylinder of the 2nd clamping head 4, still can similarly determines the reference position of the belly of track 1 with the foregoing description.
