Lining of combined crankcase with a high flange of low metal intensity for wooden sleepers

The utility model relates to the upper structure.

railway track, in particular to rail fastenings on wooden sleepers.

Known lining crutch bonding with a high flange of low metal, having two vertical, restricting the bed under the rail flanges in the form of a truncated cone in cross section. . The ribs are made with horizontal grooves in which holes for crutches are located, which fasten the sole of the rail to the lining, also in the shelves of the lining there are holes for crutches fastening the lining to the sleepers. The lining is made of reduced metal consumption by reducing the overall thickness of the lining, while the ratio of the height of the lining at the location of the shelves and the height of the rails to the length of the lining is made in

ranging from 0.02 to 0.06, and the ratio of the width of the upper and lower parts of the flanges in the range from 0.4 to 0.5. (decision on the grant of a patent for a utility model, application No. 2003113698 dated 05/13/03, “Lining for crutch bonding with a high flange of reduced metal consumption).

The known crutch lining, which is adopted as a prototype of the claimed utility model, has a number of disadvantages, one of which is expandability of sleepers when driving the crutch at the attachment of the lining to the sleepers, which in turn entails a violation of traffic safety during operation, railways, as there is pulling out crutches from the thawed part of the sleepers.

The problem to which the claimed utility model is directed is to increase the reliability of fastening the rail to the lining and sleepers while ensuring the safety of the rolling stock.

This technical result is achieved through the use of a lining of a combined mount with a high flange and low metal consumption for wooden sleepers. The design of such a lining provides for fixing the lining to a wooden sleeper by means of screws, the use of which

excludes splitting of sleepers during fastening, for this purpose round holes are made in the shelves of the lining. The rail is secured to the lining with crutches. To ensure tight contact of the screw head with the lining, the lining shelves are made without a bias and a shoulder, the absence of which ensures a reduction in metal consumption.

The utility model is illustrated by drawings:

Figure 1 shows the lining of a crutch bond with a high flange of reduced metal consumption in the context;

Figure 2 shows the lining of the combined fastening with a high flange of reduced metal consumption for wooden sleepers in the context;

In Fig. 3 shows a General view of the lining of the combined mount with a high flange of low metal consumption for wooden sleepers.

The lining of the combined fastening with a high flange of reduced metal consumption for wooden sleepers consists of two vertical flanges 1 having a cross-sectional shape of a truncated cone. Each flange along its length is divided by horizontal grooves 2, in which holes 3 are located under the crutches, fastening the sole of the rail to the lining. In the shelves 4

the lining is made of four round holes 5 for screws that fasten the lining to a wooden sleeper. The contact plane 6 of the screw head to the lining shelf is parallel to the contact surface 7 of the lining to the sleeper.

Thus, the set of essential features of the claimed utility model provides: reduction of the lining metal consumption by 6.7%, increase of its operational properties, as well as the reliability of rail fastening to the lining and sleepers while ensuring the safety of the rolling stock.
