Definitions
- the invention relates to a method for welding two rails of a track according to the features cited in the preamble of claim 1.
- the object of the present invention is now to provide a method of the generic type, with which a welding of the rails is also possible above the neutral temperature.
- FIG. 1 and 2 each show a view of a welding unit
- Fig. 3 to 7 are schematic representations of the welding process.
- a welding unit 1 shown in FIGS. 1 and 2 consists essentially of two mutually spaced-apart aggregate halves 2, which are displaceably connected to one another in the longitudinal direction by compression cylinders 3 arranged in a common horizontal plane and running parallel to each other.
- Each of the two aggregate halves 2 consists of two - about a running in the rail longitudinal axis - tong-like pivoted to each other unit levers 4 with effective as an electrode jaws 5 of two jaw pairs 6. These are each for contact with a front rail end 7 of a first rail 8 and a rear rail end 7 a second rail 10 is provided.
- the two in the transverse direction of the track opposite each other aggregate levers 4,5 are connected in their upper end by a clamping cylinder 12 for pressing the jaws 5 to the rails 8,10 together.
- the welding unit 1 is suspended from a telescopic crane attached to a welding machine 20.
- the power is supplied by a generator arranged in the welding machine 20 and a hydraulic pump.
- a control device 13 is provided for carrying out the welding process and recording various welding parameters.
- the desired pressure force is calculated after entering the neutral temperature, the current rail temperature and the rail type in the control device 13 by a microprocessor.
- a rail anchor 16 are formed (s. 3 and 4).
- a hydraulic rail pressure device 19 is frictionally engaged with the adjacent rail ends 7 of second and third rail 10,14 contacted, while on the abutting the rail ends 7 of the first and second rail 8,10 the welding unit 1 is placed and non-positively connected by the jaws 5 with the two rail ends 7.
- the welding process is initiated so that the two detected by the jaws 5 rail ends 7 are moved under the action of the compression cylinder 3 from each other until adjacent end faces 9 of the two rail ends 7 form a welding gap w s of 3 millimeters.
- a force measurement takes place permanently via the pressure in the compression cylinders 3 and, via the distance of the two jaw pairs 6 from each other, also a displacement measurement.
- the actual welding is started while the current is being supplied, and the mutual movement of the two pairs of clamping jaws 6 is reversed in a mutual movement (see Fig. 7) and thus the burning-off phase is initiated with the final upsetting impact.
- This Zuschiolo is carried out according to the program while maintaining a slight distancing of the rail ends 7 to each other and finally terminated at a compression force of 30 N / mm 2 with the compression stroke. In this phase, a shortening of each rail end 7 occurs by about 17.5 mm. This naturally leads to a drop in the actual rail voltage below the desired compressive stress.
- the attainment of the desired compressive stress is registered via the upset cylinders 3 and can automatically be calculated with the involvement of the hydraulic cylinder 21 of the rail-holding device 19. be valid. But it is also possible to control the loading of the hydraulic cylinder 21 by hand, wherein the compressive stress occurring in the region of the welding unit 1 is checked on a display.
- This method ensures that after completion of the rail welding in the rails 8, 10 which are welded together, the desired compressive stress correlating with the current rail temperature prevails.
- hydraulic cylinders 21 of the rail-holding device 19 are depressurized.
- the welding unit 1 can already be solved immediately after removal of a Sch Strukturwulstes of the rails 8,10 and lifted.
