(54) DEVICE FOR LIFTING RAILWAY TO BALLAST

The invention relates to devices for the construction and repair of a railway track and is intended for use in the working bodies of track machines for lifting a rail and felting grid onto ballast. It is known a device for lifting a railroad track onto a ballast containing an articulated truss on one part of which rail clamps are fixed, in front and behind of which four stationary racks are fixed on the truss to hold the strings inside them to level the ballast under the raised track grid. It does not allow the fixation of the position of the relief of the falling grating when it is raised to a predetermined height. It is also known a railway lifting device; 1cn of a track on a ballast comprising a truss supported on running trolleys, lifting power cylinders mounted on a truss, bearing grippers for rails, ballast frames located on both sides of the longitudinal axis of the device, strings mounted on a truss, and knives mounted on both sides of the longitudinal axis of the device can be rotated by drives in the horizontal plane. Such a device does not provide accurate xsation of the under-rail rail grid at a given height and tracking the installation of knives at a certain distance from the ends of the sleepers depending on the type of ballast, which reduces its effectiveness. The goal of the acquisition is to increase the efficiency of the device. To achieve this goal, the device is equipped with sensors mounted on the blades of their position and additional blades rigidly mounted on the ballast frames in the horizontal plane at an angle to the longitudinal axis of the device, and these blades are mounted on the blaster frames. In addition, the drives turning the knives are made in the form of power cylinders. On r, 1 shows a device for lifting the railway track on the ballast, a general view; figure 2 - section aa in Fig .; on fig.Z - section bb in figure 2. The device contains a farm 1 supported on chassis - trolleys 2, lifting hydraulic cylinders 3 mounted on farm 1 and connected to rail grippers 4, ballaster frames 5. Knives 6 and additional knives 7 are mounted on bluster frames 5. Additional knives 7 are rigidly fixed on the ballaster frames 5 and are located in a horizontal plane at an angle to the longitudinal axis of the device. Knives 6 secured # | on the ballaster frames 5 with the help of hinges 8 with the possibility of rotation by force -cylinders 9 in the horizontal plane. The position sensors of the knives 6 consist of rods 10 with elements 1I fixed on them and two-position switches 12 with contact plates 13 and 14. The rods 10 are fixed at one end to the frames of rail grips A and the two-position switches 12 are mounted on knives 6. Strunk 15 are designed for leveling and plating ballast and fixed on knives 6. Working process for lifting the rail and tie rail and putting it on the ballast,. With the {{change} of this device for lifting a railway track, the following procedure is carried out. With the help of hydraulic cylinders 3, the rail clamps 4 are lowered from the transport position down to the contact with the heads of the rail threads and capture them. Simultaneously with these ballast frames 5, by means of the Mechanism of their Drive (not shown), they are transferred from the transport position to. work The strings 15, which are locked between the knives 6, are pulled under the rail-grating lattice. At the same time, the required gap O between the ends of the sleepers and the edges of the knives 6 is established with the help of cylinders 9. The gap Q is set depending on the type and condition of the ball . After this hydraulic cylinder w 3, the rail claws 4, and with them the rail and sleeper rail, are hung out to a predetermined height. Then, with the help of a hitch (not shown), the entire device moves along the railway track, during which a continuous process of raising the rail-sleeper grid takes place. At the same time, the strings 15 plan the ballast under the raised rail grill, and the knives 6 and 7 take the excess ballast from the shoulders of the ballast section and direct it to possible gaps formed between the ballast surface planned by the strings 15 and the bottom surfaces of the sleepers, as well as into the sleeper boxes. The movement of the ballast under the influence of knives 6 and 7 from the shoulders of the ballast prism in the direction perpendicular to the axis of the path is indicated by arrows B. It is ensured by the fact that the distance between the working surfaces of the blades 6 and 7 measured in the direction perpendicular to the axis of the path tapers in the direction of movement of the device. As a result, the fixed position of the rail and tie grid is fixed in height when lifting it, which in this case does not depend on the condition of the ballast surface planned by the strings 15, but is determined only by the height of lifting of this grid. The device due to the redistribution of ballast from the shoulders of the ballast section along the path, fixes the hung rail grating at a given elevation in the longitudinal profile and in the level. When setting the clearance, the gap between the trestle and the sleepers and the edges of the knives 6 is kept straight with the sleepers using the joint operation of the sensors of the position of the knives 6 and the power cylinders 9. When the size of the gap SI is changed, the element 11 fixed on the rod 10 is in contact with one of the contact plates 13 or 14 of the two-position mouse. The clutch 12, as a result of which a control signal is generated to the hydraulic drive spool (not shown) and under the influence of which the power cylinder 9 moves the knife 6 until the size a is restored. Thus, a device for lifting a railroad track on both straight and curved sections of the track ensures fixation of a predetermined position of the rail-sleeper grid when it is lifted both in the longitudinal profile and in level. This makes it possible to significantly improve the quality of the track position in the longitudinal profile and level when lifting the rail-sleeper grille to the ballast, as well as to increase labor productivity when performing subsequent alignment of the track, which increases its efficiency. The application of the proposed device allows to reduce labor costs for ballasting works at 25 h / d per I km of track. 1.
