Description

The utility model relates to freight gondola cars with hatches in the floor of the body, and concerns the designs of hatch covers.

A gondola hatch cover is known, containing a flooring with a width H, fixed on a frame of rigidly interconnected front and side beams of a U-shaped section, side and central loops with shanks rigidly connected to the flooring, side loops are placed with their shanks between the vertical shelves of the side beams, cm RU 63785, B65D 90/10, publ. 06/10/2007 (prototype).

The technical problem of this gondola car hatch cover is its low reliability, in particular, the weak connection between the hinge shanks and the cover deck, leading to the detachment of the hinges from the deck.

The technical result of the proposed utility model is to increase the reliability of the gondola hatch cover.

The claimed technical result is achieved by a gondola car hatch cover containing a flooring of width H, fixed on a frame of rigidly interconnected front and side U-shaped beams with shelves, rigidly connected to the flooring of the central and side loops with shanks of length h, the side loops are placed with their shanks between the vertical flanges of the side beams, the ratio of the length h of the shanks of the side loops to the width H of the flooring is made from 0.3, the flooring between the side beams along its rear edge is reinforced with an overlay, to which the shank of the central hinge is rigidly connected;

the ratio of the length h of the shanks of the side loops to the width H of the flooring is not more than 0.7;

the flooring is reinforced with a central beam, rigidly connected at one end to the front beam, the second end is rigidly fixed to the overlay, while the central loop is placed with its shank between the shelves of the central beam;

the ratio of the length h of the shank of the central loop to the width H of the flooring is made from 0.3;

the ratio of the length h of the shank of the central hinge to the width H of the flooring is not more than 0.7.

the ratio of the length h of the shank of the central loop to the width H of the flooring is made from 0.3 to 0.7;

the upper flange of the side beams in the area where the side loop shanks are located can be made with a through groove.

The claimed utility model differs from the prototype in that the ratio of the length h of the shanks of the side loops to the width H of the flooring is made from 0.3, the flooring between the side beams along its rear edge is reinforced with an overlay with which the shank of the central hinge is rigidly connected;

the ratio of the length h of the shanks of the side loops to the width H of the flooring is not more than 0.7;

the flooring is reinforced with a central beam, rigidly connected at one end to the front beam, the second end is rigidly fixed to the overlay, while the central loop is placed with its shank between the shelves of the central beam;

the ratio of the length h of the shank of the central loop to the width H of the flooring is made from 0.3;

the ratio of the length h of the shank of the central loop to the width H of the flooring is not more than 0.7;

the upper shelf of the side beams in the area of the side loop shanks is made with a through groove.

Such differences from the prototype give reason to assert that the proposed technical solution meets the criterion of patentability of a utility model - novelty.

The hatch cover of the gondola car contains a flooring 1 with a width H (Fig. 1, 2), fixed on the frame 2 of the interconnected front beam 2.1 of a U-shaped section with vertical and upper shelves and side beams 2.2 also of a U-shaped section. The front beam 2.1 and the side beams 2.2 are rigidly connected to the flooring 1. For movable suspension on the gondola car body, the hatch cover is equipped with side hinges 3 and a central hinge 4. The side hinges 3 are made with shanks 3.1 of length h, placed in the internal cavity between the vertical shelves of the side beams 2.2 . The ratio of the length h of the shanks 3.1 (Fig. 3) of the side hinges 3 to the width H of the flooring 1 of the hatch cover is made from 0.3. The ratio of the length h of the shanks 3.1 of the side loops 3 to the width H of the flooring 1 of the hatch cover can be made no more than 0.7. The flooring 1 between the side beams 2.2 along its rear edge is reinforced with an overlay 5 (Fig. 4), with which the shank 4.1 of the central loop 4 is rigidly connected.

The flooring 1 of the hatch cover can be reinforced with a central beam 2.3, also of a U-shaped section, connected at one end to the middle section of the front beam 2.1, the second end is fixed on the plate 5, while the shank 4.1 of the central loop 4 is placed in the internal cavity between the vertical shelves of the central beams 2.3. In this case, the shank 4.1 of the central hinge 4 can also be made with a length h, which is 0.3 of the width H of the decking 1 of the hatch cover, and also the specified shank 4.1 can be made no more than 0.7 of the specified width H (Fig. 5).

The execution of the shanks 3.1 of the side loops 3 and the shank 4.1 of the central loop 4 of length h, maintained in given ratios from 0.3 and not more than 0.7 of the width H of the decking 1 of the hatch cover, creates additional stiffening elements for the decking of the hatch cover 1, increasing its strength and rigidity. The length h of the shanks 3.1, 4.1, made within the indicated range limits, ensures their stronger fixation on the flooring 1, obtained due to the increased length of the welds.

Making the length h of the shanks 3.1, 4.1 less than 0.3H does not provide the necessary strengthening of the connection between the specified shanks and decking 1. When making the length h more than 0.7H, the weight of the cover increases. The increased weight of the cover causes an increased load on the hinges attached to the body and carrying the cover, which can lead to their deformation or breakage, which in general will reduce the reliability of the hatch cover. The flooring 1 in the area of the hinges 3, 4 is reinforced with an overlay 5, with which the shank 4.1 of the central hinge 4 is rigidly connected. To further increase the reliability of the cover, the flooring 1 can be reinforced with a central beam 2.3, which acts as a stiffener in the central part of the flooring 1.

The upper shelf of the side beams 2.2 in the area of the shanks 3.1 of the side loops 3 can be made with a through groove 2.2.1 (Fig. 6, 7). The presence of such a through groove 2.2.1 makes it possible to simplify the installation of the shanks 3.1 of the side hinges 3, to carry out visual control over the technical condition of the connection of the shanks 3.1 with the flooring 1 directly during the operation of the gondola car.

These elements provide a technical result - an increase in the reliability of the gondola hatch cover.
