Description

The invention relates to a device for the construction and repair of a railway track and is intended for use in the working bodies of machines for raising a rail-sleeper grid onto ballast and placing it on predetermined marks. A device is known for lifting a railroad track onto a ballast comprising a truss unlocking on undercarriages, lifting power cylinders mounted on the truss, carrying rail clamps, ballast frames located on both sides of the longitudinal axis of the device, strings attached to the ballast frames, and ballast knives, consisting of two parts, one of which is fixed on the corresponding ballast frame, and the other part is hinged with the possibility of turning in the horizontal plane, and located in the horizon plane at an angle to the longitudinal axis of the device 1}. This device provides an accurate fixation of the raised rail grill at a given height and tracking the installation of knives at a certain distance from the end of the sleepers depending on the type of ballast, but it creates a large resistance force when it re-moves the rail gauge, the ballast from the shoulders the ballast sent under the bottom surfaces of the sleepers goes under them to a limited depth, which is accompanied by a decrease in the carrying capacity of the rail-sleeper run, and the supplied ballast under the bottom surfaces of the sleepers flows out from under them in the area of the ends of the sleepers that non-provides stabilization of the position of the track. The purpose of the invention is to expand the functionality of the device by stabilizing the position of the track. . This goal is achieved by the device for lifting the railway track to the ballast containing a truss supported by running trolleys, lifting power cylinders mounted on the truss, bearing rail clamps, ballast frames located on both sides of the longitudinal axis of the device, strings, mounted on ballast frames, and ballast knives, consisting of two parts, one of which is rigidly fixed to the corresponding ball.t frame and the other pivotally rotatable in a horizontal plane; and located in the horizontal plane at an angle to the longitudinal axis of the device, provided with adjustable elastic elements installed between the ballast frames and hinged parts of the ballaster knives, and mounted on the latter feedcases and devices located parallel to the longitudinal axis of the device, as well as vibrators directed to this axis of action, fixed on the pads. FIG. 1 shows a device for lifting a railroad track to a ballast, general view; in fig. 2, section A-A in FIG. one; in fig. 3 shows a section B-B in FIG. 2, The device comprises a frame 1 resting on the undercarriage 2 on farm 1. Lifting power cylinders 3 are mounted, connected to rail grips 4, and ball aster frames 5 on which ballast blades b are mounted in the horizontal plane at an angle to the longitudinal axis of the device. The ballast knives 6 consist of a fixed front 7 and a rear movable 8 parts. The fixed parts of the 7 ballast blades 6 are rigid; mounted on the ballast frames 5. The movable parts of the 8 knives b are connected to the fixed parts of the 7 knives using hinges 9 with a vertical axis. The movable part 8 of the ballast blades 6 is made with feed wedges 1.0 and pads 11, the latter being located in a horizontal plane parallel to the device's axis. The platforms II are equipped with vibrato 12 directed to the path. Elastic elements 13 are installed between the movable parts of the knives 6 and 6 and 5 frames. The elastic elements 13 are installed, the tension force of which is adjusted by screws 14. The strings 15, designed to level the ballasts, are fixed to the tailings 6. Knives 6 The workers have elevations of 16. The working process for lifting the plastic grill and setting it on the ballast with the EFFECTS of the proposed device is performed as follows. By means of the lifting cylinders 3, the claws 4 are lowered from the transport position BEFORE contact with the rail head and the yarn. At the same time, the ballast rsill 5s are transformed from a gear to a position using a drive mechanism x (not shown). Under the rail grille, the mouths are strung by the strings 15 and secured in the blades b. Then, the feed lines 10 plant vehicle under the rail-grating grid, and screws 14 establish the necessary tension force of the spring elements 13, depending on the type of ballast used, with a clearance of defined clearance between the ends of the sleepers and platforms 11. Thereafter, lifting cylinders 3 with grippers 4, a rail grating is hung out at a predetermined height and vibrators 12 are inserted into the pitch. Then, the device moves along the railway line, during which continuous f | The process of lifting the rail grid. Simultaneously, the chord 15 is spread ballast underneath the raised rail grid and 6allasterCh s knives used psschgioschie wedges 10 and withdraw excess ballast from the shoulders of the ballast, and it is fed into possible gaps formed between raeravneknoy otrunkami 15, .ballasta surfaces and lower surfaces of the sleepers , @t is also a spalchiki. The direction of movement of the ballast under the influence of the knives 6 and the feed wedges 10 from the shoulders of the ballast prism in the direction perpendicular to the axis of the path is shown in FIG. 2 arrows & It is balanced by the fact that the distance between the working surfaces of the blades b and the feeding wedges 10, measured in the direction perpendicular to the axis of the track, narrows in the direction from the fixed parts 7 to the movable parts 8.

The wedges 10 and vibrators 12, carrying out directional vibration impact on the side, the paths, enhance the process of supplying ballast from the ballast arms to the raised rail on the grate and ensure its flow for the rail areas, which increases the load bearing capacity of the rail that is lifted to the desired direction. lattice. The weighted design of this clearly fixes the given height, position of the rail-railed grating when it is raised. TSacotttoe the position of the rail-sleepers slice in: the case under consideration, and it depends. from the level of the ballast surface by the strains 15, and is determined only by the height of its lifting.

The presence of vibro-impact on the moved ballast contributes to a significant decrease in the drag force when moving the device along the solid-state track.

The impact of the plc dad 11 on the sub-bottom of the lower surfaces of the sleepers ballast is accompanied by its additional UL at its ends, which helps to stop the flow of ballast in the zone where the fmaji ends are located.

When excess ballast is pushed into the pathway, it is squeezed into the sleeper. drawers from the established gap, between the pads and the ends, ital, and i, with insufficient ballast dosing, the ballast knives are lowered by an amount greater than the lifting height, resulting in a sufficient amount of ballast under the sleepers and thereby its effect

o the installed clearance will be stable, regardless of the amount of ballast eadosed into the path.

The proposed device due to redistribution, ballast from the shoulders

5 ballasts of the prism along the way fix / hang the hung rail-sleeper rail: the grid at a given point in the longitudinal profile and level, at the same time ensuring the supply of ballast

0 under-rail zones of the raised rail and tie grid, reduces the resistance force when moving the device-:. along rail tracks and also prevents ballast leakage

5 in the area of the ends of the sleepers.

. The clearance between the ends of the sleepers and the pads 11, set in the adjustment, both on straight and curved sections of the track, is maintained due to the impact of:

0 of the elastic elements 13 to the movable parts of 8 ballast knives b.

In order to transfer the device from the working position to the transport string, 15 are released from the connection.

5 with ballaster blades b, with the help of screws 14, the load is removed from the elastic elements 13, the feeding wedges 10 are removed from under the sleepers and the ballaster frames 5 are transferred to the transport position, at the same time the clamps 4 are disconnected from the rail head and lifting cylinders 3 are also transferred to transport position.

five

Thus, the proposed device ensures the fixation of a predetermined position of the rail-sleeper grid when it is lifted both in the longitudinal profile and at the same level, simultaneously;

0 ensuring the supply of ballast to the under-rail zones of the rail rail and grating, which increases its carrying capacity, reduces the resistance force when moving the device along the rail track, and

5 also prevents the ballast filed under the sleepers from flowing out in the area of its location at the ends of the sleepers. All this taken together significantly increases the affect of the operation of the device.
