The invention relates to means for mechanizing track work and can be used when it is necessary to create tensile or reducing compressive stresses when laying rail lashes.

A device is known for longitudinal displacements and changing the length of a rail lash, comprising two grips for rails, including elements for interacting with necks and rolling surfaces of rails, draw bars connecting about dp rails and placed on both of the rail lashes, and at least one hydraulic cylinder.

A disadvantage of this device is the need to use at least two hydraulic cylinders with a two-sided working stroke and the relative inconvenience of connecting the rails (setting the bolts through the slotted holes).

The purpose of the inventions is to increase the efficiency of the device by reducing the time to install the device.

The inserted target is achieved by the fact that a device for longitudinal movement and changing the length of a rail scourge containing two grippers for rails, including elements for interacting with necks and rolling surfaces of rails, connectors connecting grips for rails and placed on both sides from rail lashes, and at least one hydraulic cylinder, is provided with a support for the hydraulic cylinder; elements for interacting with rail necks are mounted on elements for interacting with rolling surfaces of the rails using parallel One of the longitudinal planes of symmetry of the device and pivotally attached to the arms of the indicated elements, with parallel elements connected to the rolling surfaces of the rails, are connected by means of an axis with the tools at the ends passing through the longitudinal grooves which are made along parallel pipes and installed with the possibility of interaction with the lateral sides of these elements, and the parts of parallel pipes that interact with them are wedge-shaped, and the hydraulic cylinder p placed along the longitudinal plane of symmetry of the device between the said support and the element for interacting with the rolling surface of the rail of one gripper for the rail, one ends of the rod are connected to the support, and their other ends with the element

to interact with the rolling surface of the second rail grip rail.

Figure 1 shows the device, top view; figure 2 is a view of And figure 1; on fig.z section bb in figure 1 (ti gi not shown); FIG. 4 is a section along the line BB in FIG. 2 (not shown).

The device for the longitudinal movement and change of the length of the rail is mounted on the anchor rail 1 and the extended (movable) rail 2 and contains rods 3, one ends of which are connected to the support 4 and placed on both sides of the rails 1 and 2, the Device also co5 holds two grips for rails consisting of elements 5 for interacting with rolling surfaces of rails and elements b for interacting with rail necks, and hydrocylicd 7, Tg and 3 connect grippers for

0 rails, one of which is mounted on the rail 1, and the other on the rail 2. The hydraulic cylinder 7 is located along the longitudinal plane of symmetry of the device between the support 4 and the element 5 of one of the grips

5 dp rail. Elements 6 are connected to elements 5 by means of parallel t g 8 with longitudinal grooves a, through which the axes 9 pass with stops 10 at the ends. T g 8 are located on both sides of the longitudinal

0, the planes of symmetry of the device and are hinged on the elements 6 for interacting with the rail necks by means of axles 11. On the legs 8 there are handles 12 for lifting the device. Cables 8 are installed with the possibility of interaction with the lateral sides of the elements 5, and the parts interacting with them of the rings 8 are made wedge-shaped.

The device works as follows.

0 On each rail - anchor 1 and extendable 2 - are installed by raising for 8 of the movable elements of the 5 grippers, while lowering the 8 of 8 due to their wedge-shaped form

5, the engagement of the fixed elements 6 of the gripper with the rail 1 and 2. T & gz 3 with the support 4 can be made in one piece with the element 5 of one of the grips, then the pull 3 and the support 4 simultaneously with the movable element 5 is installed along the rail axis, close to

The support 4, from its inner side, is then mounted to the hydraulic cylinder 7, in contact with its end part with the movable gripping element 5.

When the hydraulic cylinder 7 is turned on, its force is transmitted to the moving elements 5 of the claws, in one case through the support 4 and tgu 3, in the other case through the second end of the hydraulic cylinder 7. Moving along the rail, the moving elements 5 of the clamps create a bias of the elements 5 and 6 at the expense of their swivel with tgami 8, thereby ensuring the clamping of the rail head.

Upon further movement of the rod of the hydraulic cylinder 7, its force is transmitted to the rails 1 and 2, ensuring their movement (lengthening) to a predetermined limit, when it is possible to fasten them in the traditional way.

When the hydraulic cylinder 7 is disconnected from the power supply system, the longitudinal forces disappear, hence the imbalance of the g and b elements disappears and their grip to the rail decreases sharply. When lifting t g 8, the rails are released from the fixed elements of the b grippers.
