Description

 The track machine is designed to carry out track work on raising the track grate and straightening it, distilling the sleepers according to marks and unscrewing butt gaps during the construction of new railway lines, second tracks and repairing the railway track of 1520 and 1435 mm gauge, with a rail-sleeper grid on wooden and reinforced concrete sleepers, rails P43, P50, P65 and all types of ballast.

 Also, a track machine can cut ballast from sleepers and replace sleepers in the repair of a railway track.

 The effective use of the track machine is largely determined by its small weight, high transport speed and quick-detachable working bodies, which allows it to be delivered to the object both by self-propelled railway, and by road, rail, water and other modes of transport.

 Known track machine containing a self-propelled chassis, on the frame of which by means of devices for hanging the working bodies mounted appropriate working bodies (ed. Certificate. USSR N 658203, class E 01 B 33/00, 1979).

 Known track machine containing a self-propelled chassis, on the back of the frame of which there is a device for hanging a working body on which is installed the corresponding interchangeable working body (ed. Certificate of the USSR N 1073351, class E 01 B, 33/18, 1984).

 The technical result of the invention is the expansion of the technological capabilities of the track machine, as well as the quick, without the use of lifting means, replacement of working bodies, depending on the type of track work performed. In addition, the machine can provide power to both electrical equipment and hydraulic drives of the machine and hydraulic drives of the working bodies, as well as power to the electrified tool, for example, electric tamper.

 To achieve this technical result, a track machine containing a self-propelled chassis, on the rear of the frame of which there is a device for hanging the working body on which the corresponding replaceable working body is mounted, is equipped with a second device for hanging the working body located on the front of the frame of the self-propelled chassis each device for hitching the working body consists of a frame rigidly attached to the frame of the self-propelled chassis with vertical guides and a lifting frame with brackets for installation and a corresponding interchangeable working body mounted on the frame of the said device with the possibility of movement by the drive along vertical guides.

 In addition, each lifting frame is mounted on the frame of the corresponding device for hitching the working body with the possibility of fixation in the transport position, while the machine is made with two drive wheel pairs spaced along the frame of the self-propelled chassis, the drive of one wheel pair being located on the left side of the machine, and the drive the second wheel pair is located on the right side of the machine.

 Track machine (Fig. 1-3) is universal, has a railway track with a hydraulic drive of all mechanisms. The machine consists of a self-propelled chassis 1 and mounted working bodies: a lifting-leveling mechanism 2 and a device 3 for installing sleepers on marks and dispersing butt gaps.

 Interchangeable equipment can also be installed on chassis 1: a device for replacing sleepers, a device for cutting ballast from sleepers (not shown in the drawings).

 The machine also includes a device for moving the car off the railway track. The machine is made with eyelets for slinging and can be removed from the track with a lifting mechanism.

 Self-propelled chassis 1 (Fig. 1) consists of a frame 4, supported by two wheelsets 5 and 6, spaced in the longitudinal direction of the frame 4, cab 7, power unit 8, front device 9 for hanging the working bodies, rear device 10 for hanging the working bodies, brakes 11, rollers 12 and 13.

 The cabin 7 is mounted in front of the frame 4. The engine and generator of the power unit 8 are installed in the middle of the frame 4.

 The front 9 and rear 10 devices for hitching the working bodies are rigidly mounted respectively on the front and rear parts of the frame 4. The brakes 11 are mounted on the axes of the brackets of the rear wheelset 6. The brackets of the rollers 12 and 13 are rigidly attached to the frame 4, symmetrically to the center of gravity of the machine and are used to exit of the car from the road to the side of the road by a special device (not shown) from the machine set for passing trains when working in the "window".

 Frame 4 is a one-piece rigid structure.

 Wheel sets are designed to move the machine along the railway track. Front 5 and rear 6 wheel drive pairs. The front wheelset 5 has a drive located on the left side of the machine, and the rear wheelset 6 is on the right. The diagonal arrangement of the wheel drives ensures a stable position of the machine on the railway during acceleration and braking of the machine.

 The front device 9 for hitching the working bodies (Figs. 4 and 5) is intended for mounting removable working bodies (lifting-leveling mechanism 2 or a device for replacing sleepers) and transferring them from the working position to the transport one or vice versa.

 The front device 9 includes a frame 14 with vertical guides 18, rigidly fixed to the chassis frame 4 1, a lifting frame 15 with brackets 16 and 17, mounted for vertical movement along the guides 18 by means of sliding bushings 19 and 20 located on each of the sides of the frame 15, the hydraulic cylinder 21 for lifting the frame 15 to the transport position, which is pivotally mounted through the eyelets with the rod on the frame 15, and the housing on the lower cross member of the frame 14, the latch 22, by means of which the frame 15 in the transport position is fixed relative to respect to the frame 14. Brackets 16 and 17 are supported axes 23 and 24 of brackets 25 lift-straightening mechanism 2 for fixing it to them.

 The device for replacing sleepers is mounted on the front device 9 in the same way as the lifting-leveling mechanism 2, i.e. by means of axles and brackets similar to axes 23 and 24 and brackets 25.

 The rear device 10 for hitching the working bodies (Fig. 6 and 7) is designed for mounting removable working bodies (device 3 for installing sleepers on the marks and dispersing butt gaps or devices for cutting ballast from sleepers) and transferring them from the working position to the transport and vice versa.

 The rear device 10 includes a frame 26 with vertical guides 28, rigidly mounted on the frame 4 of the chassis 1, for example by means of bolted connections, a lifting frame 27 mounted for vertical movement along the guides 28, by means of sliding bushings 29 and 30 located on each of the sides the frame 27, the hydraulic cylinder 31, which through the eyes of the rod is fixed on the frame 27, and the body on the upper cross member of the frame 26, a latch 32, by which the frame 27 in the transport position is fixed relative to the frame 26. On the frame 27 on the axis of symmetry of the machine in the longitudinal plane there is an arm 33 pivotally connected to the eye 34 of the rod of the hydraulic cylinder 35 of the device 3. On the frame 27 are brackets 36 that are connected to the brackets 37 and 38 of the device 3 for mounting it in the transport (vertical) position. The brackets 36 are located on both sides of the bracket 33. The brackets 33 and 36 are designed to install a corresponding interchangeable working body, which is connected to the brackets using fingers or other fastening elements.

 A device for cutting ballast from sleepers is mounted on the rear device 10 in the same way as the device 3, i.e. through the eye of the rod of the hydraulic cylinder and the brackets for mounting the device in the transport position, similar to the eye of the rod 34 of the hydraulic cylinder 35 and the brackets 37 and 38.

 The brackets 16 and 17 of the front device 9 are connected to the brackets 25 of the lifting-leveling mechanism 2 both in the transport and in the working positions of the machine. The brackets 36 and 33 of the rear device 10 are connected to the brackets 37 and 38 and the eye 34 of the device 3 in the transport position of the machine. In the operating position of the machine, the brackets 36 are disconnected from the brackets 37 and 38, and the bracket 33 remains pivotally connected to the eye 34 of the cylinder rod 35. The brackets 36 are made similar to the brackets 16 and 17, and the bracket 33 is made elongated in the form of a console.

 The machine operates as follows.

 After transporting the machine to the place of work for lifting and straightening operations, the device 3 mounted on the rear device 1O for hitching the working bodies is in the transport position and is locked by the latch 32.

 When performing work on lifting the rail-sleeper grid and its straightening with lifting, the lifting-leveling mechanism 2 is transferred from the transport position to the working one. For this, the latch 22 of the front device 9 is manually removed from the eyes of the frame 14, the hydraulic cylinder 21 of the frame 15, connected by means of brackets 16 and 17 with the axes 23 and 24 of the bracket 25 of the lifting-leveling mechanism 2, moves down the rails 18 until it is mounted on the track rails 39. When you turn on the hydraulic cylinders 40, the grippers 41 are lowered and closed under the heads of the rails. When you turn on the hydraulic cylinders 42 lift supports 43 are supported on the ballast and the lifting rail-sleeper. When turning on the straightening hydraulic cylinders (not shown), the rail-sleeper lattice is laterally displaced by moving the central beam 44 with the grippers 41 to the left or right of the track axis. When moving the rail-sleeper lattice to the right, the left straightening cylinder is included to extend the rod, and the right one to retract the rod.

 When straightening the track without lifting, the sliding beams 45 and 46 are fixed to each other and the anchors 47 are installed instead of the supports 43. The anchors 47 during straightening of the track are buried in the ballast and fix the machine relative to the ballast. In FIG. 1 and 2 show the installation of anchors 47 in the transport position.

 To perform work on the installation of sleepers in the way along the marks, alignment of skewed sleepers, acceleration (adjustment) of rail butt clearances, the lifting-leveling mechanism 2 is transferred to the transport position. In this case, the retractable beams 45 and 46 are moved inside the central beam 44, the supports 43 or anchors 47 are lifted by the lifting hydraulic cylinder 42 to the upper position, the grippers 41 are raised by the hydraulic cylinders 40 to the upper position, the hydraulic cylinder 21 is the frame 15 connected by means of brackets 16 and 17 with the axes 23 and 24 of the bracket 25 of the lifting-leveling mechanism 2, is moved to its highest position along the guides 18 and is fixed relative to the frame 14 by inserting the latch 22 into its eyes.

 Device 3 is transferred from the transport position to the working one. To do this, the latch 32 of the rear device 10 is manually removed from the eyes of the frame 26, the hydraulic cylinder 31 of the frame 27 connected to the device 3 by means of brackets 36 and 33 is moved to its lowest position along the guides 28, by extending the stem of the hydraulic cylinder 35, pivotally connected by an eye 34 to the bracket 33 , the device 3 is lowered from a vertical position to horizontal until the rollers 48 and 49 are installed on the rails, while the brackets 37 and 38 of the device 3 are disengaged from the brackets 36.

 The operation of the device 3 during the distillation of sleepers is as follows.

 By moving the device 3 along the path by extending or retracting the rod of the hydraulic cylinder 35, the gripping fork 50 needs to be oriented relative to the driven sleepers.

 By turning on the hydraulic cylinders of the brackets (not shown) to extend the rods, the rail heads are clamped. When the hydraulic cylinder 51 is turned on, the gripping fork 50 rotates and grips the railroad tie. When you turn on the hydraulic cylinder of the mechanism for moving the sleepers, the gripping fork 50 moves the sleeper in the necessary direction to the mark, after which the gripping fork 50 returns to its original position.

 The operation of the device 3 during the acceleration of butt gaps is as follows.

 When you turn on the hydraulic cylinders of the brackets to extend the rods through the lever mechanisms, the wedges move in the grooves of the brackets and clamp the rail head.

 When the hydraulic cylinders are turned on to extend the rods, the bracket with the wedges clamped by the rail moves along the rods, accelerating the butt gap.

 The track machine, through the front and rear devices for hitching the working bodies, allows quickly and without the use of lifting means to replace the working bodies depending on the type of traveling work, which expands its technological capabilities. Devices for hitching working bodies have a simple design, easy to operate. The fixation of the working bodies in the transport position on the front and rear devices for their hitching ensures reliable and safe delivery of the machine to the object both by self-propelled along the railway track, and by automobile, railway, water and other modes of transport.

 The track machine is autonomous and does not require additional external power sources for electrical equipment and hydraulic drives of the machine and working bodies. In addition, the machine provides power to an electrified tool, for example, electric tamper.

 The implementation of wheelsets with a diagonal arrangement of wheel drives ensures a stable position of the machine on the railway during acceleration and braking.

 The machine has a small mass and for skipping trains when working through the “window” it can be pulled to the side of the road using a special tool or it can be removed from the track by lifting equipment.
