    I
    The invention relates to welding, in particular to flash butt welding by melting of rails laid in a groove.
    Famous mobile flash butt welding machine
    Rails, to be equipped with a platform with welding equipment and a hydraulic mechanism to remove burrs 1 ..
    The welding equipment in a known machine is located on a swivel bracket protruding above the front side of the machine, and is intended for welding the right and left thread of the track. The machine has its own movement drive. When moving the machine from one place to another, the bracket with the welding equipment is retracted onto the platform to protect it from damage and weathering.
     Since the machine is made in the construction of a normal rolling stock, it can move from one place of work to another, either with its own drive train or with the train. During machine operation (especially in double-track sections), special safety measures must be taken to protect the operating personnel in the field of gauge. Since the operator in the area of the ruts has to control and observe not only the movements of the feed and alignment of the welding unit itself, but also manually bring various auxiliary devices into working position (such as a mechanism for removing burrs at the welding site), it is always at the same time several people working outside the car on the railroad tracks, so that the danger from passing by driving is not completely ruled out, especially in the dark or due to bad weather and visible tees.
    The purpose of the invention is to increase labor productivity, improve operating conditions.
    This goal is achieved by the fact that a mobile flash butt welding machine for rails, a platform with welding equipment and a hydraulic mechanism for removing burrs, is provided with a support device for unloading rails from the weight of the machine.

    mounted in the front part of the platform, which in the middle part is provided with a frame bent upwards, and welding equipment and hydraulic. 5, a deburring mechanism is located in the space between the frame and the platform.
    The support device is made in the form of a support pivotally connected with
    10 by a power cylinder and designed to interact with a rail track. In this case, the support can be made in the form of a shoe designed to interact
    The t5 is with a rail track in its middle part, and the support can be made in the form of two forks designed to interact with the rail track on both sides of each of the rails.
    20 In addition, a hydraulic mechanism for deburring is mounted on the platform frame, and in the second version can be mounted on the pile. handy equipment.
    25 Figure 1 shows a movable flash butt welding machine for rails, side view; Fig. 2 shows another embodiment, a partial side view; figure 3 - view A
    Q in figure 2; Fig. 4 is a section B-B in Fig. 11 in Fig. 5 is one of the forms of welding equipment with a hydraulic mechanism for deburring.
    5 Mobile flash butt welding machine 1) can be moved by two running gears of chassis 2 and 3 along a track consisting of rails 4 and 5 and track sleepers 6. The front running gear of chassis 2 is designed as an un-driven single-axle drive part, and the rear running gear of the chassis 3 is made bi-axial and has its own running gear, shown in dashed lines.
    Made in the construction of a standard rolling stock, the machine 1 is equipped on both face sides with a puller and a buffer device 7, the machine 1 has a frame bent up in its middle part 8. 9, which is made in the form of a closed car body with cabins 10 of the driver. At the rear of the lower part of the machine 1 there is a drive motor 11 of the machine 1 and the power supply mechanisms 12 connected to it. The main percentage of the weight of the machine 3 1; falls on the rear suspension section 3. Since it is biaxial and the forward suspension section of chassis 2 opposite is single axis, then for all wheel skates 13 of the machine an approximately equal axle load is created. On platform 14, in front of the undercarriage of chassis 2 and above both rails 4 and 5, a hydraulic cylinder piston unit 15 is mounted so as to rotate around an axis 16 passing across the machine. The free end of the piston of the piston / cylinder unit 1.5 is designed as a draw hook 17. The latter serves to receive the fixed on the corresponding rail 4 or 5 of the steel cable 18. The welding machine 1 is equipped with a support device 19, which is located directly behind the chassis 2 of the chassis 2 and which is made in the form of a fixed platform 14 of a vertical cylinder-piston unit 20 with supports 21 fixed at the free end of the piston. The width of this support 21 is greater than the distance between two track ties 6 following each other to ensure reliable support of mashiv 1 on the upper side of the sleepers (Fig. 4). The support 21 is shown in solid in its upper position in which it is located during the movement of the machine, and in the working position in dashed lines). The support device 19 makes it possible to lift the machine 1 in the front suspension area of the chassis 2 so that the ramp 13 is lifted from both rails 4 and 5. The middle part 8 of the frame 9 is bent upwards to form the working space 22 of the machine, which is accessible from inside the vehicle through the doors. 23. A portion of platform 14 that bounds the working space 22 below forms a working platform 24, which can be raised and lowered by means of actuators 25. Working space 22, in addition to the flash butt welding equipment 26, contains a hydraulic mechanism for deburring 27, in place The swabs are an abrasive cut-off machine for rails 28 and, if necessary, other auxiliary mechanisms for carrying out skirt work. Equipment 64 for flash butt welding by reflow 26 is suspended by swinging on guide part 29, which is arranged so that column guide 30 can be moved along the horizontal axis of the machine from one to another side of the machine. Fundamentally, it is also possible to perform the guide column 30 itself with the possibility of moving in the longitudinal direction of the machine in order to simplify the centering of the welding equipment for flash butt welding with the melting of 26 in relation to the rail being welded 31. A mechanism for removing burrs 27 at the welding site through a pair of independent suspension arms formed by two hydraulic cylinder-piston blocks 32, soy; a; with a cross carriage 33, which can move along a horizontal, transverse guide 34 in the form of a dovetail from one side of the machine to . another one. The mechanism for removing the grata 27 is equipped with a single knife head; 25, which covers the head of the corresponding rail, which makes it possible to cut the bur 36 in a single pass. The support device 19 (Figures 2 and 3) consists of two forks 37, each of which is connected to a piston cylinder 38 connected to the platform 14 and can be rotated around a horizontal axis 39 passing transversely to the longitudinal direction of the machine. The forks 37 are installed with the possibility of interaction between the left and the right of the rail on the top side of the sleepers by means of the support nJmT 40. The longitudinal size of the support plates 40 is slightly larger than the average distance between the track ties 6 following each other. Support devices 19 made in the form of forks 37 are activated independently of each other. Thereby, it is possible to raise the welding machine 1 in the area of the front chassis of the chassis 2 on one side only, if, for example, only welding should be done on one of the two rails. . Referring to Fig. 5, the flash butt welding equipment 26 is provided with a hydraulic shear mechanism 41, with the result that the entire structure of the welding shop 1 is even more simplified. The 3TorO knife head 2 located in the intermediate space between the two pairs of contactinx pads 43, shear mechanism 41 consists of two rails placed mirror-symmetrically to the vertical plane and having the ability to rotate around the longitudinal axis 44 of the cutting dies 45, the blades of which have mating profile to the profile of the welded rail thread. The upper ends of the cutting dies 45 are pivotally connected to each other by a drive 46. Cf. the burr is performed immediately after the end of welding. The operation of the machine is carried out as follows. The machine is driven by its drive in the direction of arrow B close to the rail joint to be welded 31 and stops before the front chassis of the chassis 2 has not yet reached the junction point. Now it is suspended from the steel cable 18 in the coupling hook 17 and its other end by means of a corresponding clamp the fixture is fastened on the front part of the corresponding rail thread. The cylinder piston unit 15 is now loaded with pressure, as a result of which the part of the rail thread lying in front, which was previously released by de-mounting the rail fasteners, is pulled up to the intended distance of approximately 1 cm to the end of the welded rail string. Machine 1 then moves further in the direction of arrow B until rail joint 31 is in the area in front of the flush welding equipment 26. Thereafter, support 21 of support device 19 is pushed and the machine is raised so that the front undercarriage of chassis 2 leaves the link with both rails 4 and 5. Then, the flash butt welding equipment 26 is lowered onto the underlying rail 4 (respectively, 5 according to the line drawing in Fig. 4). The rail joint to be welded will lie with each other between the pairs of contact pads 43 between them. The ends of the rail to be welded are clamped figuratively by the contact pads 43 and aligned exactly relative to each other. Then, a welding voltage is applied to both pairs of the contact pads 43 and the p-junction joint 31 is welded in a known manner. The burr 36 formed during the welding process protrudes along the perimeter of the rail joint 31, and the rail thread is shortened therewith. After the end of the welding process, the flash butt welding equipment 26 is removed from the hook with the rail and quickly rises, after which the machine 1 moves further in the direction of operation (arrows). In such a way that the hot melt joint 36 occurs in the area of operation of the deburring mechanism 27, which is cut by the knife head 35. To weld the joint on the opposite rail thread, the flash butt welding equipment 26 immediately after the lift moves along the guide column 30 on the other side of the car. A welding process is then carried out on a different rail line. After finishing the welding work, the support device 19 is removed, after which the machine 1 moves further to the next welding point. 5, deburring is performed as follows. The cutting dies 45 on both sides are pressed against the rail. The clamping force of the carrier of a knife head 42 of a pair of contact pads 43 is removed (to the right in FIG. 5). Another pair of contact pads 43 (on the left in Fig. 5) remains further in connection with the rail. After that, the hydraulic drive for longitudinal movement of the equipment 26 moves the carrier cutter head 42 of the pair of contact pads 43 to another rail-mounted pair of contact pads 43. At the same time, the cutting dies 45 engage with the burr 36 and cut it off along the entire perimeter of the rail profile one pass. The proposed welding machine is distinguished by its quick availability for work, high productivity and ease of control placed between both front roads and parts of chassis 2 and 3 welding and auxiliary 711011768
    powerful mechanisms. As a result of leaving the machine, so that the availability of the working room is no danger to the maintenance of the inside of the machine, all welding and personnel from the side of the side works can be done quietly past the trains.
