Description

The utility model relates to railway rolling stock, namely to the design of the cantilever body parts of hopper cars.

The prior art known as a prototype cantilever part of the body of the hopper car (described in the patent for utility model of the Russian Federation No. 149541, publ. 10.01.2015, B61D 7/00), containing a discharge hopper for unloading the transported cargo. The unloading hopper is equipped with one unloading hatch with a lid and an individual unloading mechanism, made with the possibility of opening and closing the lid of the unloading hatch.

Such a technical solution - the introduction of additional unloading bins into the cantilever part eliminates the formation of places inside the body that do not empty during gravity unloading and require additional unloading operations. Thus, the internal volume of the body for transporting cargo increases.

The disadvantage of the prototype is that the wall of the hopper with the discharge hatch is located close to the profile of the spinal beam, as shown in FIG. 3 of the RF patent No. 149541. Since there are stops in the cantilever body part inside the spine beam, an absorbing apparatus and other elements of the coupler that require periodic inspection, repair and maintenance, this arrangement of the hopper covers does not provide sufficient space for access to the elements of the coupler, for example , if necessary, repair weakened rivet joints stops.

The technical problem inherent in the prototype is the low maintainability and high complexity during inspection, maintenance and repair of the elements of the coupler of a hopper car.

The technical result is to increase the manufacturability of the use and maintenance of the console part of the body of the hopper car, by reducing the complexity of the inspection, maintenance and repair of the elements of the coupler of the hopper car.

The claimed technical result is achieved by the cantilever part of the body of the hopper car, comprising a spinal beam including vertical walls, at least two discharge hoppers located symmetrically relative to the spinal beam, each discharge hopper is equipped with at least one discharge hatch with a lid, with the lid the discharge hatch is located vertically and is located at a distance of 300 to 800 mm from the nearest vertical wall of the spinal beam.

Unlike the prototype, the unloading hatch cover is located vertically and is located at a distance of 300 to 800 mm from the vertical wall of the spinal beam closest to it. Thus, for access to inspection, maintenance and repair of elements of the coupler there is a space between the covers of the discharge hatches of the opposite discharge bins, which reduces the complexity of the work and increases the manufacturability of use and maintenance.

The declared sizes are justified by the results of calculations. If the cover of the unloading hatch is less than 300 mm from the nearest vertical wall of the spinal beam, there is no access to repair the weakened riveted joints of the stops of the automatic coupler.

If the cover of the unloading hatch is located at a distance of more than 800 mm from the vertical wall of the spinal beam nearest to it, the size of the neck of the hatch is significantly reduced, which affects the bulk of the load during unloading.

The vertical location of the cover of the unloading hatch is justified by the calculation of the clamping force of the unloading mechanism. When the cover of the unloading hatch is inclined, the clamping force acting on the cover from the lever system of the unloading mechanism is less than the shear force acting on the cover from the specified mechanism. Accordingly, during the operation of the unloading mechanism, instead of pressing the lid, it will shift along the neck, which will negatively affect the tightness of the hopper and the stresses in the hinge assembly of the lid to the hopper. With a vertical arrangement of the cover, the clamping force is greater than the shear force, which ensures reliable pressing of the hatch and sealing of the hopper.

The inventive utility model differs from the prototype in that the cover of the discharge hatch is located vertically and is located at a distance of 300 to 800 mm from the closest vertical wall of the spinal beam.

This difference from the prototype gives reason to argue that the proposed technical solution meets the patentability criterion of a utility model - "novelty."

The proposed utility model is illustrated by graphic material:

in FIG. 1 shows a side view of the cantilever body part of the hopper car;

in FIG. 2 shows a cross section AA of the cantilever body part of a hopper car.

The cantilever body portion of the hopper car shown in FIG. 1, contains a spinal beam 1 with elements of an automatic coupler placed therein and discharge bins 2.

Each hopper 2 comprises a discharge hatch with a lid 3 shown in FIG. 2. The cover 3 of the unloading hatch of the hopper 2 is located vertically and is located at a distance of 300 to 800 mm from the nearest vertical wall of the spinal beam 1 (size "a" shown in Fig. 2). Bulkability of the cargo is ensured by the inclined arrangement of the walls 4 of the bins 2.

Thus, for access to the inspection, maintenance and repair of elements of the coupler located inside the spine beam, there is a space between the covers of the discharge hatches of the opposite bunkers, while due to the presence of free space between the cover and the spine beam, access to the rivets of the stops of the couplers is ensured, for due to which, the technological effectiveness of the use and maintenance of the console part of the hopper car body is ensured.
