Description

The utility model relates to railway transport, namely to universal (hatch) gondola cars operated on public tracks, and concerns the design of the holders of the hinges of the covers of the unloading hatches. The proposed utility model can be used in the production and repair of universal gondola cars.

In the CIS countries, holders of hinges for covers of unloading hatches have become widespread and are widely known from the field of technology [Industry standard "Hinge and hinge holder for a gondola hatch cover", OST 24.151.10-77, section "Hinge holder for a gondola hatch cover" OST 24.151.10.02-77 .], mounted on the upper frame beams ["Cars" edited by prof. L.A. Shadura, Moscow "Transport", 1980, pp. 315-316, fig. XI.21.] of a universal gondola car using riveted joints. Covers of unloading hatches form the floor of a universal gondola car. The holders are designed for hinged fastening of each hinge of the covers of the unloading hatches, which ensures the opening of these covers when unloading bulk cargo from the gondola car.

Known holder [Industry standard "Hinge and hinge holder for the gondola hatch cover", OST 24.151.10-77, section "Hinge holder for the gondola hatch cover" OST 24.151.10.02-77.], taken as a prototype, which is a one-piece stamped structure with a flat base and three holes in it for rivets, two bent semicircular ribs with holes for the axis of the hinged connection of the holder with the hinge of the discharge hatch cover. The well-known holder [Industry standard "Hinge and holder of the gondola hatch cover hinge", OST 24.151.10-77, section "Gondola car hatch cover hinge holder" OST 24.151.10.02-77] is rigidly attached to the I-beam of the upper beam of the frame ["Cars" edited by prof. L.A. Shadura, Moscow "Transport", 1980, pp. 315-316, fig. XI.21.] of a universal gondola car with the help of three rivets using the hot riveting method along two holes in the lower part of the flat base of the holder and one hole in the upper part, located on the axis of symmetry above the lower holes.

The disadvantage of the known toolholder is manifested in its design, namely, that the hole for the rivet of the upper part of the flat base of the holder is located in the zone of the highest power load than for rivets of the lower part of the flat base. In addition to the shear load, the upper rivet is subjected to an additional breaking force (the lower the top rivet is located, the greater the breaking force will be). This gradually leads to the weakening of the rivet connection in the upper, and then in the lower part of the flat base of the holder, and the partial loss of operability of the hinged fastening of the hatch cover hinge of the universal gondola car.

The technical result of the claimed utility model is an increase in the strength and reliability of fastening of the holders of the hinges of the covers of the unloading hatches of universal gondola cars of new designs, as well as the ability to replace the missing number of holders of a known design to use the holders of the claimed design when repairing universal gondola cars of common series (the principle of unification).

The technical result of the claimed utility model is achieved by the fact that the hinge holder of the hatch cover of the universal gondola car is a one-piece, stamped from a steel sheet structure with a flat base and two bent semicircular ribs with holes for the axis of the hinge connection of the holder with the hinge of the hatch cover, while in the flat base there are four holes of the same diameter D - from 17 to 18 mm for fastening with rivets, located in the upper and lower parts of the flat base, which has a height M, which is in the range from 130 to 140 mm, and a smooth contour of the upper part, two holes in the lower part of the base are located on both sides of the axis of symmetry S of the holder at a distance N and O to the center of each hole from 44.5 to 45.5 mm, while the distance P from the level of the centers of the holes in the lower part of the flat base to the bottom line of the contour of the flat base is from 18 to 22 mm, two holes in the upper part of the flat base are located on the axis of symmetry S d holders, the center of one of which is at a distance K - from 59.5 to 60.5 mm, and the center of the other hole at a distance L - from 89 to 92 mm above the level of the centers of the holes in the lower part of the flat base of the holder, the thickness T of which is from 11 up to 14 mm.

All holes of the flat base of the claimed utility model are equal in diameter to the holes of the flat base of the prototype. The arrangement of three holes in the flat base of the claimed utility model, characterized by the dimensions N, O (from 44.5 to 45.5 mm) and K (from 59.5 to 60.5 mm), corresponds to the same arrangement of holes in the flat base of the prototype holder . This will allow fixing the holders of the proposed model on the I-beams of the upper beams of universal gondola cars of common series.

Increasing the strength and reliability of fastening the holder (in comparison with the prototype) is facilitated by an enlarged base up to a height M - from 130 to 140 mm and the presence of a hole located on the axis of symmetry S at a distance L - from 89 to 92 mm from the level of the centers of the holes in the lower part of the flat base to the center of this hole.

Fastening of the proposed model holders is carried out by hot riveting on both sides of the I-beam wall, as well as the holders of the prototype.

The holder 1 (Fig. 1, 2 and 3) of the hatch cover hinge of the universal gondola car is a one-piece, stamped from a steel sheet structure with a flat base 2, two bent semicircular ribs 3 and 4 with holes 5 and 6 for the axis of the swivel holder 1 with a loop hatch covers, while in the flat base 2 there are holes 7, 8, 9 and 10 of the same diameter D - from 17 to 18 mm. While the flat base 2 has a height M, which is in the range from 130 to 140 mm, and a smooth contour of the upper part. In the lower part of the flat base 2 there are two holes 7 and 8, which are located on both sides of the axis of symmetry S of the holder 1 at a distance N and O to the center of each hole from 44.5 to 45.5 mm. The distance P from the level of the centers of the holes 7 and 8 of the lower part of the flat base 2 to the lower contour line of the flat base is from 18 to 22 mm. In the upper part of the flat base 2 there are also two holes 9 and 10, but they are located on the axis of symmetry S of the holder 1. The hole 9 is located in such a way that its center is at a distance K - from 59.5 to 60.5 mm above the level of the centers holes 7 and 8 of the lower part of the flat base. The center of the hole 10 is at a distance L - from 89 to 92 mm above the level of the centers of the holes 7 and 8 of the lower part of the flat base. The thickness T of the holder is from 11 to 14 mm.

The design of the holder 1 of the hatch cover hinge of the universal gondola car involves two options for attaching to the upper beam.

The first fastening option (Fig. 4, 5) is carried out by hot riveting of two holders 1 with three rivets 11, 12, 13 to the wall of the I-beam 14 of the upper beam. At the same time, the dimensional layout of the rivets 11, 12, 13 corresponds to the prototype, which ensures the unification of the claimed utility model in the conditions of repair of gondola cars of common series equipped with holders of a known design.

The second mounting option (Fig. 6, 7) is carried out by hot riveting of two holders 1 with three rivets 11.1, 12, 13 to the wall of the I-beam 14.1 of the upper beam. Since the dimensional layout of the rivets 11.1, 12, 13 differs from the prototype in that the top rivet 11.1, located on the axis of symmetry of the holder 1, is set at a level 1.5 times higher (than the top rivet of the prototype), then the tear-off force acting less, and, consequently, the strength and reliability of this rivet connection is higher.
