    • 专利摘要:
    A welding apparatus including, generally, a vertical clamping assembly having an upper and a lower clamping assembly for each of two rail sections to be welded together. These vertical clamping assemblies clamp and vertically align the running surfaces of the two rail sections, by establishing the running surfaces at a pre-determined stop level. The welding apparatus also includes a horizontal centering and aligning apparatus which has a first pair of clamping arms which engage the rail base and pre-center the rail sections with respect to one another and to the welding apparatus. The apparatus also includes a pair of spaced apart clamping arms associated with each of the rail sections which are operable to both laterally clamp the rail heads of the respective rail sections and to horizontally or laterally align the rail sections with respect to one another. Once aligned, the ends of the rail sections are welded together.

    contact electrodes connected to a current source.
    Clamping pads 9 and 11, which are airborne on top of the rail head, are fixed to the pushers 13 and 14, connected via control levers 15 and 16, through the angle levers 17 and 18c by hydraulic actuators 19 and 20 to move them up and down.
    The clamping pads 10 and 12 of the vertical presses 7 and 8, acting on the rail base, are also attached to the pushers 21 and 22 connected via the parallelogram control lever 23, through the angle levers 24 and 25 with the hydraulic actuators 26 and 27 to move them up and way down.
    In order to accurately set the height of the position of the grip of the two contact electrodes, the hydraulic actuator 20 through an additional adjustment press 28 is hinged to the frame 3. The additional adjustment press 28 may be a threaded press or, as shown, a hydraulic pressure. Thereby, the exact end position of the clamping jig And and the electrode can always be set according to the end position of the clamping jig 9 with the electrode.
    Between clips 1 and 2 there is a mechanism for centering the rails of horses 29. It contains two pairs of rotary levers 30, 31 and 32 and 33, which interact from above with the rail head, two of which 32 and 33 are flat between the clamping pads 9 and 11, as well as the new levers 34 and 35, interacting with the base of the rails. The pivot arms 32, 33 and 34, 35 are made similarly.
    Each of the pivot arms 30, 31 and 32, 33 has a rotatable nlit 36 fixedly mounted on the hub 37 by means of a clamping element 38, at the same time the hub 37 is newly mounted on the shaft 39, which is common to all the rotary levers 30-33. A rotary plate 40 is fixed on the rotatable plate 36, the shafts of which are connected to a double-arm lever 41, rotating around a finger or naphf 42, fixed in a new gate 36. At the same radial distances, but at diametrically opposite places in the levers 35, two holes 43 are made and I.
    On the rotatable plate 36, one L-shaped 45 is mounted with the possibility of movement, and the other right 46 is clamping. For this purpose, in each clamping block 45 and 46 there are made longitudinal holes 47 and 48, into which the guiding puffs 49 and 50 enter, rigidly fixed in the rotary plate 36. Both mechanical pads 45 and 46 have rods directed to the lever 41. In Each of these two rods has two holes 47 and 48,
    one of which is provided for aligning with a hole made in the turntable or 36, while another hole is coaxial with one of the holes 43 and 44 in the lever 41.
    Clamping pads 45 and 46 (see Figs. 4-6) can be connected by means of plug-in bolts 51 and 52 either with a swivel plate 36 or with a lever 41. If the clamping plate
    block 45 is connected with a rotary itai 36, then when the hydraulic actuator 40 is turned on, the clamping block 45 is rotated to the operating block 45. But if the iridescent pads are connected with the lever 41
    (see Fig. 5), when the actuator 40 is turned on towards each other, the conversely, opposite to each other. However, if the block 46 is connected to the swivel plate 36, then when the actuator 40 is loaded with hydraulic medium, only the block 45 moves to this block 46 (see Fig. 6).
    The pads 45 and 46 are fitted with stop elements 53 and 54 interlocking with the side and surface of the rail head, resulting in two welded spacing, with a rail (which, as already described, already aligned but the height of the clamping pads 9 and 11 relative to each other )
    can be installed laterally with alignment relative to each other by pressure pads 45 n 46 or along the side surface to the left (see Fig. 4), or along the side surface on the right (see Fig. 6), or along the rail symmetry symmetry (see Fig. five).
    Each pair of pivoting levers 34, 35 and 32 and 33 of a siabzhen crank ryagag 55, rigidly fastened to the sleeve 37 and
    associated with a 56 double-action drive.
    The shaft 39 serves to tension the clamps provided for the rotary levers 30-33 and formed by the clamping pads 45 and 46 to be permanently aligned with each other. The sleeve 37 is provided; 1l of that ((if the swiveling levers 32, 30 and 33, 31 intersecting each other) are rotated in the same direction at a time, the drive 56 and the lever 55 of each individual IAR exclude the load of the sleeve 36 and thereby the angles deflecting the levers 30-33.
    In order to ensure the entry of the blocks 45, 46 with their stop elements 53 and 54, always at the same height in engagement with the side and surface of the rail heads, a rotatable 36 rotatable
    levers 32, 33, is provided with a Uior element 57, which may abut against the surface of the rail head.
    Each of the actuating levers 34, 35 contains a pivot plate 58, rigidly
    rotated sleeve 59 without rotation
    by means of the clamping element 60. The sleeve 59 is rotatably mounted on the shaft 61, which is common for the rotary levers 34, 35, and parallel to the shaft 39. On the rotary plate 58, the supporting element 62 is mounted with a rotary recess 63 fitted to its base along its syringe rail. Depending on the type of alignment of the rail profiles being welded together, the supporting element 62. can be adjusted in the pivot plate 58. For this purpose, the supporting element 62 has sloping side surfaces through which it also by means of bevelled wedge elements 64 and 65 attached to the rotary plate 58, rigidly fixed on it. By moving the wedge elements 64 and 65, the distance between the supporting element 62 and the shaft 61 is adjusted, but to a value.
    Directly beside each pivot arm 34 and 35 on the sleeve 59 is fixed a crank shaft 66, associated with a double acting hydraulic actuator 67, which is provided to deflect the pivot levers 34 and 35 in one direction or another.
    The device works as follows. Rail sections are inserted into the device. Then the horizontal presses 5 and 6 are compressed, due to which the rails are fixed and retained on their wall. After that, the thrust presses 19 and 20 are turned on so that for each of the rail profiles in the area of the welded joint there is a height stop for the rail head. Then include presses 26 and 27, which, for their part, press the rail irons to the mentioned height stop. Then the rotary levers 30-33 and the levers 34 and 35 are deflected to the ground position by means of the drives 56 and 67. As soon as the thrust element 57 in the levers 32 and 33 is adjacent to the rail surface, the new levers 30-33 come to the noko position. Only now, the pressure pads 45 and 46 of all the pivot levers 30-33 are actuated using the appropriate presses 40, with the result that lateral coaxial errors, i.e., the length from the pivot arm 30 to rotary lever 31. Now you can weld by turning on current sources n hydraulic actuators 4
    sediments n presses. In the process of this welding during the subsequent period of time, the cooled rail joints are kept in mutual alignment on one side by the stop blocks 9, 11,
    and on the other - transverse clamping pads 45 and 46.
    A forward ioe device and it is possible to obtain quality welded compounds pc; ibcoB without transverse displacements and skews.
