Description

 The invention relates to railway transport, and in particular to methods of mechanization of track work associated with the unloading of rail lashes from railway rolling stock, mainly on the stage.

 A known method of unloading long products from rolling stock, which consists in the fact that in the unloading area of long products, laying gaskets, fasteners and safety shoes, the initial ends of long products are attached to the ends of the unloading cables, and the other ends of the products are disconnected from the transport fastening, by moving the railway rolling of the composition take it out from under lengthy products, then the latter is attached to the gaskets, unloading cables are fastened and they are transferred to places of new benefit narrow set security shoes (Fadeev SI Slavikovsky NA Maintenance and repair of continuous rail track. M. Transport, 1974, pp. 66-71).

 The disadvantage of this method of unloading rail lashes is the need to use specialized platforms with inclined trays, the presence of shock loads when the ends of the rail lashes fall on the base, as well as the presence of laborious manual work when connecting the unloading cable to the sole of the track rail (anchoring the rail lash).

 The technical result of the invention is to increase the efficiency of the method by eliminating shock loads upon contact of the unloaded lengthy products with the base, reducing the complexity of work during the anchoring of products, and also expanding the technical means used during unloading, including the standard equipment of repair facilities for track facilities intended for laying and disassembling the links of the path.

 The specified technical result is achieved by the fact that in the method of unloading long products from rolling stock, which consists in the fact that along the unloading area and safety shoes, the initial ends of long products are attached to the ends of unloading cables, and the other ends of the products are disconnected from the transport fastening, by moving the movable the railway train takes it out from under lengthy products, then the latter are attached to the gaskets, unloading cables are unfastened and they are transferred to new places unloading, security shoes are installed, a jib crane with a load placed on it is installed and braked at the beginning of the rolling stock, the free ends of the unloading cables are attached to the load, and before the indicated withdrawal of the rolling stock from under lengthy products, the initial ends of the latter are lifted by a crane and held until the unloading cables are weakened, unloading cables are removed, the initial ends of long products are lowered to the base and attached to gaskets, brakes cantilever crane and move to the side of the other ends of long products, after the length of the unloaded sections of long products is equal to the length of the extension of the console of the crane, unloaded ends of the products are lifted by the crane and hold them in this position until the rolling stock is completely withdrawn from under the long products, then gently lower the products on the base and attach to the gaskets.

 In FIG. 1 shows the position of the crane, rolling stock and lengthy products after lifting the initial sections of lengthy products, setting up a connecting connection between them and the load attached to the crane, as well as braking the crane; in FIG. 2-4 the same after the withdrawal of rolling stock from under lengthy products by an equal amount; in FIG. 5 the same after lowering the initial sections of long products on the base, support; in FIG. 6 the same during the movement of the crane to the giving end of a lengthy product on a rolling stock; in FIG. 7 the same after lifting the giving ends of long products; in FIG. 8 the same after pulling out the rolling stock from under the giving ends of long products and before lowering them onto the base.

 To implement the method, the following technical means were used: a two-console stacking crane (type UK-25) 1 with cargo trolleys 2, rail grips 3 and a load 5 mounted on the crane using anchor 4, as well as an economic train (rolling stock) consisting of a locomotive 6 and railway platforms 7, equipped as well as the crane with roller supports 8 for loading and transporting long products 9 and roller supports for loading and transporting packages of track links (not shown, as they are in the same transverse row with orami 8), unloading cables 10 and security shoes 11.

 The method of unloading long products from rolling stock (for example, rail lashes from rails of type R-25) is as follows.

 Before starting work, the long items to be unloaded (rail lashes) 9 are located on a rolling stock and are freed from transport fastening. At the end of the rolling stock, there is a crane 1, disconnected from the platforms 7 of the economic train. On the crane 1 is the load 5, with the help of an anchor 4 rigidly connected to it. The crane 1 is inhibited using the brake system and additionally with the help of security shoes 11.

 Before starting work along the product unloading area, wooden gaskets, fasteners and security shoes are laid out in the necessary manner. After performing these preparatory operations, lengthy products 9 have the possibility of longitudinal displacement relative to the platforms 7 and are fully ready for unloading. As a load 5 are used links of the railway track.

The sequence of operations during the implementation of the method (unloading will be performed on one pair of rail lashes on the sleepers in the middle of the gauge) as follows:
connect the unloading cables 10 to the ends of the cargo 5 and lengthy products 9 to be unloaded (Fig. 1);
sling with rail grippers 3 the initial ends of the products 9 and lift them (Fig. 1);
hold the initial ends of long products 9 in a raised position (Fig. 1);
by moving the locomotive 6 forward, the platforms 7 are pulled out from under the raised ends of the lengthy articles 9 (Fig. 2);
continue to pull the platforms 7 from under the products 9 until the tension of the unloading cable 10 is relaxed (Figs. 3 and 4);
remove the unloading cable 10 and lower the initial ends of the products 9 to the base (Fig. 5);
release the crane 1 and move it towards the giving ends of lengthy products 9 (Fig. 6);
stop the stretching of the platforms 7 at a time when there remains a portion of unloaded products 9, equal in length to the extension of the console of the crane 1 (Fig. 7);
stop the crane 1 when the console, the crane 1 is above the remaining unloaded section of the lengthy product 9 remaining on the platforms 7;
sling with rail grippers 3 the unloaded section of the product 9 and lift it above the platform 7;
with the movement of the locomotive 6, the platforms 7 are pulled out from under the raised giving ends of the articles 9;
lower the giving ends of lengthy products 9 to the base;
attach the unloaded products 9 to the gaskets and install security shoes.

 Repeat the operation when unloading the next pair of rail lashes.

 The attachment of one of the ends of the unloading cable 10 to the load 5, located on the crane 1, which is inhibited by the security shoes 11, provides longitudinal immobility of the initial ends of long products 9 from the action of longitudinal friction forces when pulling platforms 7 from under these products. in the event that the forces of resistance to longitudinal displacement are greater than the forces causing displacement. The connection through the unloading cable 10 of a lengthy product 9 includes a braked crane 1 in the forces of resistance to the displacement of the product 9, which eliminates the need to hook it onto the sole of the track rail and the associated laborious work to remove the ballast (especially frozen) necessary for such gearing.

 Maintaining the initial ends of long products 9 at the loading level, achieved by raising them slightly with a crane 1, before being pulled out from under the platforms 7, is necessary in order to shocklessly lower them onto the base. But such a lowering of the initial ends of long products 9 is possible only after disconnecting them with the unloading cable 10, which, in turn, is possible in the absence of longitudinal forces in it, that is, when the resistance forces already unloaded to the base of the section of the long product 9 are greater than the resistance forces the site of the product located on the platforms 7. A sign of such a power imbalance is the weakening of the unloading cable 10 connecting the long product 9 and the load 5.

 Thus, the connection through the unloading cable 10 of the initial ends of long products 9 and the anchor 4, located on a fixed crane 1, and maintaining these cranes at the level of their loading ensures their longitudinal immobility above the unloading place on the base until they can be shocklessly lowered on the base.

 In order to shocklessly lower the giving ends of the lengthy products 9 to the base, they are also supported at the loading level by slinging them and raising them slightly with a crane 1, and these operations are performed after the goods being unloaded 9 do not interfere with the slinging of the section of the lengthy product remaining on the platforms 7. 9. In practice, these operations are possible when the unloaded section of the product 9, which is located on the last platform 7, remains and the console of the crane 1 can be placed with the lifting ends of the product i am 9.

 The method of unloading long products from rolling stock can be used when unloading old-year rail lashes loaded on a stage onto platforms equipped with roller conveyors and used for stacking, disassembling and transporting links of the railway track, while impacts of the ends of unloaded products in contact with the base and labor costs are reduced during their anchoring.
