Description

FIELD OF TECHNOLOGY

This utility model relates to the construction of bodies for freight railway gondola cars with unloading hatches.

BACKGROUND

There are various technical solutions in this area. Known RU patent for utility model No. 76617 (IPC: B61F1 / 08, B61D17 / 10; published September 27, 2008). The frame of a universal gondola car with hatches in the floor of the body includes a spine beam, pivot and transverse melee beams and a longitudinal I-beam mounted on the spine beam, bearing rows of paired holder hinges fixed to the wall for hinging with the body manhole covers.

Known RU patent for utility model 157920 (IPC B61D3 / 00, B61F1 / 02, published December 20, 2015) "Gondola with unloading hatches", which is the closest in combination of essential features to the proposed utility model and is selected as a prototype. The gondola car described in this patent contains a body, which includes a frame, a floor with unloading hatches with covers, side walls and end walls placed on the frame, which consists of a spinal beam, intermediate beams, pivot beams and end beams. The spinal beam is made of reduced height and consists of two vertical walls, united by one horizontal shelf in a single structure. Hinges for the covers of unloading hatches are fixed on each vertical wall of the spinal beam.

One of the main disadvantages of the known gondola car bodies is the low efficiency of unloading through unloading hatches located above the carts in the cantilever parts of the body due to the fact that the elements of the carts limit the angle at which the covers of the unloading hatches open.

Thus, the problem of the known technical solutions is the low efficiency of unloading through the unloading hatches located in the cantilever parts of the body, and the inconvenience of their maintenance. The creation of the proposed technical solution is aimed at solving this technical problem, namely, to create an improved design of the gondola car body, which increases the efficiency of unloading gondola cars and ease of maintenance.

DISCLOSURE OF THE ESSENCE OF A USEFUL MODEL

This technical problem is solved due to the fact that in the proposed body of a freight railway gondola with unloading hatches, comprising a frame including a spine beam and longitudinal beams, and unloading hatches with covers located in the cantilever body parts. The covers of the discharge hatches are fastened to the longitudinal beams of the frame by means of fasteners, and the distance (D) between the axes of the fixing means of the covers of two adjacent discharge hatches in the transverse direction is in the range from 450 mm to 2000 mm, and the width (E) of the covers of the discharge hatches in the transverse direction direction is between 400 mm and 1200 mm.

The technical result of the claimed utility model is to increase the efficiency of operation of the body of a freight railway gondola with unloading hatches, expressed in increasing the efficiency of its unloading and in improving the service conditions of such a gondola.

The proposed fastening of the covers of unloading hatches located in the cantilever parts of the body to the longitudinal beams of the frame provides an increase in the efficiency of unloading the body of the gondola due to more precise release of the cargo, as well as an increase in the opening angle of the unloading hatches, and facilitates the repair in case of breakage of any part of the unloading hatch due to the close location of the discharge hatches to the side walls of the gondola car.

The indicated ranges of values, namely, that the distance between the axes of the fastening means by which the covers of said discharge hatches are attached to the longitudinal beams of the frame is in the range from 450 mm to 2000 mm, and the width of the covers of said discharge hatches in the transverse direction is in the range from 400 mm to 1200 mm, provide optimal dimensions of the unloading hatches, which allow to maximize the efficiency of unloading the body of a freight railway gondola with unloading hatches and ease of maintenance.

Fixing means can be made in the form of loops, eyes and rollers.

IMPLEMENTATION OF A USEFUL MODEL

In FIG. 1-6 shows the body of a gondola car, which contains a body 1, a frame 3 containing longitudinal 5 and spinal 6 beams, trolleys 2, covers 4 of discharge hatches. The covers 4 are located in the cantilever parts of the body 1, above the trolleys 2, and are attached to the longitudinal 5 beams of the frame 3, located closer to the side walls of the body 1 in the transverse direction. The covers of 4 unloading hatches are attached to the longitudinal 5 beams of the frame 3 using fastening means in the form of loops 7. The distance D between the axes of the loops is in the range from 450 mm to 2000 mm (recommended distance is 1280 mm), and the width E of the cover 4 of each unloading door lies ranging from 400 mm to 1200 mm.

Depending on the design of the body of the gondola car, covers 4 of hatches, trolleys 2 and brake equipment, the width E can vary from 400 mm to 1200 mm With a width E equal to 1200 mm, the hinges will be located practically on the spinal beam 6, in this case, the distance D will be 450 mm, while the area of the hatch cover 4 will be maximum, but the opening angle of the cover 4 is small. If you want to provide a larger opening angle of the cover 4, you should reduce the width E, up to 400 mm. A smaller width E is not advisable, since this will provide a small opening for pouring cargo, and with a width E of 400 mm, the distance D will be 2000 mm.

Thus, the proposed gondola car body has improved operational characteristics in comparison with the known structures, namely, it provides ease of maintenance and more efficient unloading of a freight railway gondola with unloading hatches due to a more precise release of cargo, as well as an increase in the opening angle of the hatch. The proposed fastening of the covers of unloading hatches in the cantilever body parts of the gondola car, above the bogies, to the longitudinal beams of the frame, as well as ensuring the distance between the axes of the hinges of the covers of these unloading hatches in the range from 450 mm to 2000 mm and the width of the covers of these unloading hatches in the transverse direction ranging from 400 mm to 1200 mm helps to simplify repairs in the event of a breakdown of any part of the unloading hatch due to the proximity to the side walls of the gondola.

This utility model is not limited to the specific options disclosed in the description for illustrative purposes, and covers all possible modifications and alternatives that fall within the scope of this utility model defined by the utility model formula.
