The invention relates to railway transport, and in particular to methods of mechanization of track works associated with storage rail lashes on intermediate sites, warehouses, including unloading from railway rolling stock and loading him rail lashes.

Currently, the railway network is being widely implemented seamless way, requiring significantly increased transportation and warehousing rail lashes as inside the track and with its outer side intermediate areas-warehouses.

The known method of loading, unloading rail lashes with railway rolling stock inside of a rut. Transportation rail lashes to the place of laying perform at a special composition, which can be shipped 12 lashes, the longest of which is 800 m Spetsstal has an electric windlass with rope and sheave pulleys to pull the submersible rail lashes to the device to secure the ends. At the tail end of spetssostav installed equipment for loading and unloading of the pipe. The last platform is equipped with protivooskolochnye devices and has two inclined tray, the lower ends of which are lowered to the path and located at a height of 0.26 m above the surface of the rail. The free ends paged pair of whips ropes to recognize Aut to rail the thread path, and the other ends of the same pair at the same time released from the fastening head on the platform. Smooth moving part is unloading lashes to the middle of the gauge. When loading the ends of the pair of lashes is charged with the traverse crane in protivobuksovochnoy device. Then the crane with trolley devices coming on the scourge and their ends are fixed on a movable carrier, with which the scourge delay on the part, finally the ends of the lashes delay on the part of the winch. Shipped scourge is fixed in the locking device (Seamless path / Vgilbert, Npointed, Nbere and other edited Vgilbert, Alamagan. - M.: Transport, 2000, s-269).

The disadvantages of this method are the presence of shock loads when the fall ends of the rail lashes on sleepers during unloading, the unloading only inside track and a limited amount of stock whips. The nature and sequence of actions when the curvature of the pipe in which the ends of the lashes forcibly bend at the same time not only horizontally, but also vertically, and forcibly led into the working bodies of the guide devices do not provide the minimum level of force working bodies on the whip, causing, first, used heavy manual labor, secondly, exceeded the allowable stress in the whips and metrocentro the operations of the working bodies, thirdly, it is not safe, and the fourth, while there are cases tilting lashes and emergency breakdowns.

There is a method of storing whips outside gauge with additional frame, providing a lifting rail lashes, removal and laying lifted lashes beyond the ruts in the immediate vicinity (U.S. Pat. 2171870 RF, MPK7 EV 29/05, Appl. 26.05.99). The disadvantages of this method are the small storage capacity of rail lashes outside of the track and directly from the gauge proximity, due to the purpose and operation of actuators and limit their overall capabilities.

There is a method of loading and unloading rail lashes with railway rolling stock and warehousing lashes over limit gauge (brochure Slovakia "Composition for manipulating long rail whips CDK-2 (CDK-2)"), adopted for the prototype. Railways of Slovakia and the Czech Republic use the special composition of the transporting rail lashes to the place of installation. The loading on the structure, unloading and warehousing rail lashes to a distance of 2 meters from the axis of the gauge provides the manipulator with hydraulic drive, with the ability to rotate 360°and two arrows with independent hydraulic control. The known method has a number of nedostatki is:

1. Small storage capacity outside the track, not providing the need for rail production in the winter, when not produced work on laying the rails. This is due to the appointment, the principle guiding devices and limit their overall capabilities, and improving the latter is impossible without change first. For example, to increase the size of storage is not enough simply increasing flight of arrows hydraulic cranes, as, apart from the deviations of the scourge in the direction of greater than before, the amount necessary to straighten, and also on the large size, as in places of removal and paving or on platforms spetssostav, either on-site warehouse, and to keep it from shifting and tilting, and it is impossible to perform a single capture of the manipulator without the use of additional power stops and auxiliary unsafe manual labor.

2. Education forms a flat S-shaped curve, the projection of which in the plan should take the whip when unloading or loading, the number of influencing the guide stops shall be not less than four, which is explained in the following. Any flat S-shaped curve is obtained from a straight line by bending its ends in opposite directions two movable stops affecting to the hospitals, with the support of the median area of the segment located on two different sides of the fixed stop, which amount is four. Thus, for normal stacking all pairs of lashes to the desired location on the warehouse ground or Elisaveta you must have at least four pairs of guide stops (rail clamps), whereas their counterparts less than partially, but not sufficiently compensated by the control points in stock and Elisaveta. Not enough because with this installation method requires the use of manual labor, as well as frequent tilting lashes, deviations from linearity styling, slipping whips to the side, etc.

3. The nature and sequence of the curvature of the pipe in which the ends of the lashes forcibly bend at the same time not only horizontally, but also vertically and forcibly led into the working bodies of the guide devices do not provide the minimum level of force working bodies on the whip, causing, first, used heavy manual labor, secondly, exceeded the allowable stress in the whips and metal working bodies, thirdly, it is not safe, and the fourth, while there are cases tilting lashes and emergency breakdowns.

A method for storing rail lashes on the equipped area is under the inside and the outside of the track path, including unloading resovskogo composition or loading it whips by equipping rolling stock complexes devices, allowing you to store the required volume of rail lashes at the intermediate areas - warehouses.

The technical result of the proposed method is to increase the amount of storage rail lashes on the outside of the track at a distance from the gauge allowable envelope approximation buildings to train staff; improving the efficiency of the method by reducing the load of effort into whips and guides the working bodies, as well as reduce manual labor by expanding the possibility of using technical means.

The technical result is achieved by the fact that in the process of warehousing rail lashes produced in equipped areas inside and outside the track way, including unloading with resovskogo composition or loading at him rail lashes using additional relsovoznymi composition traction and guide equipment with rail clamps, consisting in the fact that the ends of the pair of rail lashes connected by flexible connections with fixed stops on the warehouse ground and tighten the scourge with composition or pull them on it when moving the part in the appropriate direction, while the scourge semakau is in the rail clamps guide equipment and Flex captured the ends of the whips in the form spatial curves, according to the invention outside the track path rail scourge warehoused in the form of pyramidal stacked in multiple layers with stacking with the estimated interval under the lower tier of the linings slip, and between the tiers gaskets bearings with flanges along the edges of each tier, and affect every lash and keep it from tilting, at least four rail clamps located at the end of the composition and trailed him an inclined ramp, with first ends of a pair of whips off or tighten it until the moment of their support at the same time on the Playground and composition, providing samoiscelenie ends vertically, then rail grips, located in the extreme positions, down to the curved ends of the lashes, close on them and bend them in the plan in the form of S-shaped curves, the ends of which correspond to the locations and directions in stock and on the composition, after which the gripper is fixed relative to the ramp and resovskogo composition and forth, moving composition, continue unloading or loading a pair of lashes to complete.

The direction of flexible connections, in accordance with the location of the whips in stock, change and fix by means of horizontal beams with adjustable guide stops, which is placed across the path and passing through it in the appropriate upravlyaushih points of a pair of flexible connections, which are secured to stationary supports on-site warehouse.

The completion of the loading of the whips on the composition until it locks in locks provide with inventory rails located at the end of the stock and secured at the ends to fixed supports on-site warehouse, with the other ends of which sostakovic lashes at the end of loading, push them to the castles and fix them, then rassadina joints and tighten inventory rails with composition, returning them to their original position.

1 shows a diagram of the mounting ends of the rail lashes flexible connections for stationary stops on the warehouse ground when unloading or loading.

Figure 2 shows the scheme of the storage rail lashes inside the track path and outside the track in the form of pyramidal stacked in several layers.

Figure 3 shows the fixing of flexible connections with horizontal beams and the inventory position of the rails at the completion of loading of whips.

The method consists in that the ends of the pair of rail lashes 1 connect by flexible connections 2 with fixed stops 3 site 4 warehouse and tighten the scourge 1 resovskogo composition 5 or pull them on it when moving structure 5 in the appropriate direction. The tightening of the pipe 1 to part 5 is carried out by lifting the ends of a pair of tie-1 using standard lifting equipment, such as konsolen the x valves 6, and part 5. Gets under the raised ends of the pipe 1 for fixing them in the rail clamps guide 7 equipment 8. After closure of the ends of a pair of tie-1 in the rail grippers 7 of them bent in the form of spatial S-shaped curves.

On the outside of the track rail way scourge warehoused in the form of pyramidal stacked in multiple layers with stacking with the estimated interval under the lower tier of the linings of the slide 9, and between the tiers - pads roller 10 with the flanges 11 along the edges of each tier. Rail scourge 1 of each tier have the opportunity under the action of thermal stresses to move along the warehouse, and the flange 11 to prevent the fall of the pipe 1 with layers and side thermal emission of the pipe 1.

When unloading or loading a pair of whips 1 on each act and at the same time keep it from tilting, at least four rail grippers 7 arranged in a row along the part 5 at its end and trailed him an inclined ramp 12. At the beginning of the unloading or loading the ends of the pair of lashes 1 draw with composition 5 or tighten it until the moment of their support at the same time to the site 4 and part 5 without exposure to rail grippers 7, located in the initial position away from the whips 1, providing samoiscelenie ends of the pipe 1 in the vertical direction. After that rail clamps 7 dive torches etc is drawn to the curved ends of the pipe 1, close on them and bend in the plan in the form of spatial S-shaped curves, the ends of which correspond to the locations and directions of the on-site 4 warehouse and relavation part 5. Then the gripper 7 is fixed relative to the ramp 12 and resovskogo composition 5, and further, the moving part 5, continue unloading or loading a pair of whips 1 to completion.

To prevent shock ends of rail lashes 1 on the surface 4 under lowered the rail ends of the pipe 1 is installed, for example, jacks (not shown).

The direction of flexible connections 2, in accordance with the location of the pipe 1 at site 4 warehouse, change and fix by means of horizontal beams 13 with adjustable guide lugs 14, which is placed across the path and passing through it in the respective guide points a pair of flexible links 2, which is fixed for a fixed stops 3 site 4 warehouses. You can mount a pair of flexible connections 2 for the elements of the path.

The completion of the loading of the pipe 1 to 5, up to fix them in the locks on 15 part 5, provide with inventory rails 16 located at the end of platform 4 warehouse and fixed at the ends on the fixed stops 3 to site 4. The other ends of the inventory rails 16 sostakovic with all zagrozenia rail lashes 1 SPE is territorial plates 17, can easily pass through rail clamps guide 7 equipment 8. Whip 1 at the end of the loading push through inventory rails 16 when the moving part 5 to castles on 15 part 5 and fix them, then rassadina pads 17 and tighten inventory rails 16 of part 5, returning them to their original position. The need for retention of the pipe 1 at the time of completion of loading in the rail grippers 7 is dictated by the requirement of maintaining longitudinal stability of the ends of the pipe 1, including an inventory of rails 16, when pushing with great force.
