    The invention relates to welding, in particular to methods and equipment for resistance butt welding, and can be used to make a jointless rail track. The aim of the invention is to simplify the equipment for welding a rail scourge of rail sections of length 400 m or more. FIG. Figure 1 shows schematically a welding train with which the proposed method is carried out; Fig. 2 shows a movable welding plate form, top view; in fig. 3 - welding device, side view; in fig. 4 is the same, top view; FIG. 5 shows a section A-A in FIG. four; in fig. 6 fixed uzep welding device; in fig. 7 is a section BB in FIG. 5 (construction of clamping devices; Fig. 8 shows the shape of the clamping elements in the case of welding of a continuous pipeline.) A method for welding a rail band from previously prepared rail sections is as follows. A rail section 1, the length of which can reach 400 m and more, is served from the plazform 2 through the welding device 3 installed on the welding platform 4 and the traction device 5 installed on the platform 6 in such a way that its opposite end is at the welding position. reaches 400 m and more, then the other end of the protrusion. from the traction device 5 and lowers onto the sleepers, forming a loop-length of 15-30 m. Then the next rail section 1 is fed from the platforms 2 to the welding device 3, setting its end on the welding axis. The welded ends are fixed in clamping devices, melted by reciprocating the movement of the welded end of the rail section lowered onto the sleepers, which makes it possible to make a flexible loop with a length of 15-30 m and set it off. Upon completion of welding, the pull unit pulls the welded rail lash out of the welding unit until the end is only that the welded rail section is at the welding position. The next rail section is drawn out from platform 2 and welding is performed in this way. As a traction device 5, it is possible to use a device of known construction used for working with rails. The Composition of the traction device 5 includes one or several pairs of opposite rollers 7 for tight clamping and moving the continuous rail and a number of platforms for laying the obtained continuous rail 8 on the railway bed 9. Similarly, known devices can be used as a winch device 10. Typically, the winch device 10 comprises a cable, at the end of which there is a means for quick connection with the rail .; The device can be manually or automatically grinded to wind the cable and draw the continuous rail 1 from the platforms 2 and feed it to the movable welding platform 4. The platform 11 carries two rollers 12 and 13 that engage with a continuous rail 1 for lifting and pressing. of the latter as fed to the movable welding platform 4. Platform 11 connects a series of platforms 2 (only one of them is shown) that transport a number of continuous rails. The length of continuous rails can reach quarters: miles or more her. The welding device 3 is mounted on the movable welding unit 4 with the possibility of longitudinal movement relative to it, which allows welding of two rail lashes using one welding device (Fig. 2). The welding device 3 has a unit 14 which is fixed in the longitudinal direction the longitudinal direction of the node 15, both of which are based on the frame 16. The mobile node 15 is installed with the possibility of vertical movement relative to the frame 16. With the help of the nodes 17 and 18, and the fixed node 14 is installed with possibility of lateral movement relative to the frame 16 via nodes 19 and 20 (Figure 4). The stationary assembly 14 includes two side walls 21 and 22 separated by some distance, between which four vertical walls 23-26, which are box-shaped frame distant from frame 16 and placed inside The non-box-shaped frame is held inside the frame 16 and can be displaced in the transverse direction relative to the latter by means of movable block assemblies 27 and 28 attached to the vertical walls 23 and 26, respectively, and T-shaped horizontal beams 29 and 30 which are rigidly fixed to the vertical walls 31 and 32, respectively. Vertical walls 31 and 32 are positioned between and attached to side walls 33 and 34 of frame 16 (Fig. 6). The insulating part 35 of movable block assemblies 27 and 28 is designed to electrically isolate the fixed part 14 from frame 16, 3554 Located in the center between the side walls 21 and 22, the massive steel element 36 is rigidly attached to the upper edges of the vertical walls 23-26 and joins between them. On the upper surface of the element 36 are steel gaskets 37 and 38 and an electrode 39 of hard wear-resistant copper, they are located at a distance along its length. B. Composition of the fixed assembly 14 includes two clamping devices 40. and 41 for clamping the rail and adjusting devices 19 and 20 for precisely placing horizontally the fixed assembly 14 for leveling the rail end clamped in it with the end of the rail with which it must be welded. The rolling unit 15 also includes a box-shaped frame formed by two side walls 42 and 43 separated by some distance (Fig. 4), four vertical walls 44-47 fixed between them at a distance, centered between the side walls 42 and 43 is placed a massive steel element 48 which is rigidly fixed and extends over the upper edges of the vertical walls 44-47. Element 48 has steel gaskets 49 and 50 and an electrode 51 made of hard wear-resistant copper; they are mounted on its upper surface along the length at a certain distance from each other. The box-shaped frame of the movable assembly 15 may longitudinally and vertically move within the frame 16, at its right end, with the aid of a shaft 52, which is part of assembly 18, and at its left end, with a vertical wall 53, which is part of assembly 17, On a vertical the wall 54 has a horizontal shelf 55 which is rigidly fastened to it and to the side walls 33 and 34 of the frame 16. The shelf 55 has a guide groove 56 in which the guide block 57 is fastened to the element 48, fastened to the element 48, the box-shaped frame of the mobile unit 15 is moved longitudinally relative to the frame 16, and during its longitudinal displacement the guide block 57 slides forward and backward along the guide groove 56 in the flange 55, whereby the guide block 57
    supports alignment box-shaped frame relative to the frame 16.
    The longitudinal movement of the box-shaped frame of the movable unit 15 is accomplished by G using the tool 18.
    A vertical wall 53 supporting the left end of the box-shaped frame of the movable unit 15 is secured and held at its lower end by means of a lever rod 58 attached to the eccentric shaft 59. The upper end of the vertical wall 53 is attached to the element 4S. When the lever arm 58 is moved, the vertical wall 53 rises or lowers, adjusting vertically the position of the rels. In addition, the vertical wall l 53 is deformable in the sense that it can be bent when transversely moving the movable assembly 15 relative to the frame 16 during the welding operation. B the composition of the movable node 15 includes two clamping nodes 60 and 61.
    At each of the opposite ends of the main frame 16, there are hoppers 62 and 63 for guiding the rails to the welding device. Shelves 64 and 65 are located at the entrance to the rail funnels 62 and 63, designed to bend rail ends upward and to protect roller assemblies 66 and 67. The latter contain rollers 68 and 69 on which the rails rest and steel gaskets 70 and 71, which interact with respective rollers 68 and 69 to protect them from damage when the ends of the rails are fed into the welding device. The roller assemblies 66 and 67 are rotatably and rotatably mounted and have hydraulic cylinders 72 and 73 for raising and lowering the rollers 68 and 69 and, consequently, the rails that rest on them.
    The composition of the fixed 14 and rolling 1J. nodes include two clamping devices 40, 41 and 60, 61, respectively. The design of the clamping devices is similar (Fig.7
    The clamping device 40 (Fig. 7 contains a hydraulic cylinder 74, located vertically and attached to a massive steel element 36, while it is placed between the vertical walls 23 and
    24 box-shaped frame neg: sdB;: 1K:; o1o of node 14 and is protected by them (FIG. 5); A horizontal lever 76 attached to each of the opposite ends of the levers 77 and 78 is attached to the piston 75 of the hydraulic cylinder 74. The hinges 77 and 78 are hinged. The ends of the levers 79 and 80, which are hinged on shafts 81 and 82, respectively, are fastened "In each of the levers 79 and 80, there is a lever ha 81 and 82, which is hingedly fastened to its upper end by means of the axis of the hinge 83, The ends of the lever tg 81 and 82 carry clamping elements 84 and 85 co. respectively, which captures the neck and the base of the rail.
     With this design, when the piston 75 of the hydraulic cylinder 74 is pushed, the lever system, which includes the levers 76 - 80, rotates and the upper ends of the levers 79 and 80 are closed so that the levers 81 and 82 and the locking elements 84 and 85 on them the ends are engaged with the rail neck and squeezed it. A horizontal clamping force on the order of 500 kN acts on the neck,
    The vertical clamping force is transmitted to the base of the rail also by means of lever bars 81 and 82 through spring units 86 and 87, which include the ENTRIER 88, one end of which is pivotally connected to the corresponding lever 79 or 80 via the hinge axis 89. Ban 88 passes through the sleeve 90 which is part of the lever rod 82 and holds the spindle 9.1 through which the shaft 88 protrudes, in addition, there is a thread on it. A spring 92 is fixed around the shaft 88 inside the sleeve 90, which engages with the lower surface of the spindle 91 and transmits the clamping force of the lever arm 82, and the clamping force of approximately 200 kN can be adjusted using the spindle 91, Around the spring nodes 86 and 87 are provided fencing 93,
    For lateral movement, the box-shaped frame of the fixed assembly 14 is supported with respect to the frame 16 by means of horizontal guide rails 29 and 30 and movable block assemblies 27 and 28. The threaded end of shaft 54 (FIG. 6) is connected via a threaded coupling 95 with movable block node 27 and held inside universal joint 96, mounted inside inside assembly 97 attached to wall 34. A ratchet 98 is coupled to shaft 94, through which the transverse movement of the box-shaped frame of the non-movable assembly 14 is adjusted the ends of the rails. A slight angular correction can be made using a slight bend provided on the horizontal guide rails 29 and 30. A similar horizontal adjustment device interacts with the movable block assembly 28. The vertical alignment of the rail ends is provided by the movable node 15. The end of the box-shaped frame of the movable node 15 near the welding axle is supported by a vertical wall 53, the lower end of which is attached to the lever bar 58. The latter is hinged to the eccentric shaft 59 and its cone with a piston of a hydraulic cylinder 99, under the action of which the lever pull ha 58 rotates the eccentric shaft 59 to raise and lower the vertical wall 53, and therefore the box-shaped frame of the movable assembly .15 for vertical alignment of the end clamped in it. rail with the end of the rail clamped in the fixed assembly 14. The mobile assembly 15 is also supported by the shaft 52, which, in turn, is supported by two separated lever arms, 100, which are rotatably supported by the eccentric shaft 101, controlled by the hydraulic cylinder 103. The action of the hydraulic cylinder 103 causes the lever rod 1.02 to rotate, and therefore the eccentric shaft 101, to raise or lower the lever rod g 100 and the shaft 52 supporting the movable unit 15. Due to this The vertical position of the rail clamped in the movable assembly 15 is established. During butt welding, one of the ends is reciprocated using two spaced hydraulic cylinders 104 pivotally fastened at one end to the frame 16. The pistons 105 of the hydraulic cylinders 104 are connected to the corresponding lever rods 100. During operation, the hydraulic cylinders 104 rotate the lever rods 100 around the shaft 106, causing the shaft 52 and the moving unit 15 to move forward and backward with respect to the frame 16, butt fusion welding. Through the channels (not shown) to the welding transformer 107, a primary current is supplied through the cables (not shown). From the transformer 107, the welding current (secondary side) goes through the bus bars 108 and jumpers 109 to the electrode 39 (the current to the electrode 51 is similarly supplied). From electrodes 39 and 51, current flows into the base of the rails. Depending on the need for current, additional transformers or transformer-discharge groups can be provided. The device works as follows. The end of the rail 1 is fed to the rail funnel 62, and a continuous rail runs along the roller 68, to prevent movement of the rail along the steel gaskets 37 and 38 and the electrode 39. When the end of the rail 1 is placed at the welding position of the welding device 3, the hydraulic cylinder 72 lowers the roller 68 so that the rail 1 sits on the steel gaskets 37 and 38 and the electrode 39. Then the hydraulic clamping cylinders 74 of the clamping devices 40 and 41 are hydraulically controlled, and through the lever system, which includes the lever brackets 76 - 80, the clamping elements 84 and 85 in d t-engage and clamp the rail neck 1. The vertical clamping force is also transmitted to the rail base 1 by means of lever bars 81 and 82 due to the action of spring assemblies 86 and 87. Now the rail 1 is tightly clamped in the fixed assembly 14 of the welding device 3. Similar Thus, the welded end of the rail scourge is rigidly clamped in the movable assembly 15 of the welding device.
    The welded ends of the rails are aligned horizontally with the help of snapshots 98 knots 19 and 20. A slight angular correction can be made using small bends, horizontal guide rails 29 and 30, then the welded ends are aligned vertically with the hydraulic cylinder 99. The hydraulic cylinder piston 99 rotates the lever Tug 58 and eccentric shaft 59 fastened to it, raising or lowering a vertical wall 53 that supports one end of the movable unit 15. The other end of the movable unit 15, and with it the continuous rail 13, it is also possible to raise or lower for vertical alignment of the rails by controlling the hydraulic cylinder 103, the piston of the hydraulic cylinder 103 rotates the lever rods 100 and the shaft 52 supporting this end of the movable unit 15. At the completion of the vertical and horizontal alignment of the continuous rails, butt welding is performed reflow. Welding is provided by applying electric current to the electrodes 39 and 51 and communicating reciprocating movement of the welded end of the rail scourge by means of hydraulic cylinders 104, which control lever rods 100, which in turn move the shaft 52 forward or back, supporting the rotor assembly 15. These movements are adjusted in accordance with known parameters in order to achieve flash welding. Vertical wall 53. is deformable or flexible, so it is bent with moving the movable assembly 15 forward or backward with respect to the main frame 16 during the butt-weld welding operation.
    When the ends of the rails are connected, the jaws 40, 41, -60 and 61 open. The welded whip is lifted on rollers 68 and 69 by the action of hydraulic cylinders 72 and 73 to prevent damage to electrodes 39 and 51 when the welded whip is removed from welding device 3.
    The proposed welding device can also be used to form other continuous stretch articles, for example pipelines. In this case, it is only necessary to provide for a different form of clamps and frame elements, which should satisfy the shape of the products being welded. For example, the welding device (Fig. 8) is adapted for welding the pipeline 110, the electrode element 111 and the ends of the clamping devices 112 and 113 have a shape corresponding to the circumference of the pipeline so that the latter can be clamped and welded as described above. similar products.
