Description

The proposed utility model relates to the field of railway transport, namely to devices for placing and securing cargo containers during their transportation on a platform car and can be used in the design of platform car frames.

From the prior art, from the Russian Federation patent for utility model No. 209316 "Device for fastening containers on a vehicle", a device for fastening a container on a vehicle is known, comprising a folding base with a fitting head, pivotally mounted on the vehicle frame using an axis, the folding base is provided with a lock, wherein the lock is made in the form of a latch with a hook, spring-loaded mounted on an axis, mounted with its ends on supporting brackets fixed to the vehicle frame, the latch hook interacts with the folding base when holding the folding base in the working position. This technical solution is adopted as a prototype.

The proposed utility model solves the technical problem of the presence of deformation in the places where the folding base connects to the axle. In addition, the technical problem of the low reliability of the design of the device for securing the container on the platform car, which occurs due to the presence of the above deformation, is solved.

The technical result achieved by the utility model consists in reducing the deformation that occurs at the junction of the folding base with the technological axis, and in increasing the reliability of the design of the device for securing the container on the platform car.

The technical result is achieved due to the fact that the device for securing a container on a platform car contains a limiter and a folding base with a projection installed using a process axis on the frame of the platform car, the process axis is placed in an L-shaped groove made in the end wall of the folding base, the most distant from the longitudinal axis of the frame of the platform car, while the process axis is inseparably connected to two sections of the groove.

In this case, the technological axis can be connected to two sections of the groove made in the end wall of the folding base, the most distant from the longitudinal axis of the platform car frame, by welding.

In this case, a recess can be made in the folding base, forming two protrusions.

Fig. 1, Fig. 3 and Fig. 4 show, respectively, a fully and partially folding fitting stop of a platform car.

Fig. 2 shows a general view of the frame of a platform car.

The claimed device 2 for securing a container on a platform car 1 comprises a folding base 3 with a projection 4 and a limiter 5. The folding base 3 is installed using a process axis 7 on a frame 8 of the platform car 1. The process axis 7 is placed in a groove 10 of an L-shape made in the end wall 6 of the folding base 3, which is the most distant from the longitudinal axis of the frame 8 of the platform car 1 (this axis is the longitudinal axis of symmetry of the frame 8 and is shown in Fig. 2). In this case, the process axis 7 is inseparably connected to two sections 11 and 12 of the groove 10.

The geometric shape of the device 2 for securing the container ensures the prevention of the possibility of unwanted vertical movement of the empty container, preventing the container from turning and tipping over under strong transverse wind loads.

The loads that act from the containers on the platform car 1 during its movement or maneuvers are supported mainly by the stops 13 (longitudinal loads), rigidly fixed (welded) to the side beam of the frame 8 of the platform car 1.

One of the most technologically advanced designs of device 2 for fastening the container of a platform wagon 1 is the connection of the technological axis 7 with two sections 11 and 12 of the groove 10 using welding.

One of the most technologically advanced designs of device 2 for securing container of platform wagon 1 is the implementation of a recess 9 in folding base 3, which forms two protrusions in folding base 3, as shown in Figure 1.

In the prototype, in the design of the device for fastening containers on a vehicle, the folding base is pivotally connected to the axle, for example, by means of two ears according to Figure 2. When using the device for fastening containers on a vehicle, deformations will occur at the junction of the axle with the folding base due to constant friction of the outer surface of the axle against the inner surface of the hinge (ear). Thus: placing the process axle in an L-shaped groove, which is made in the end wall of the folding base, the most distant from the longitudinal axis of the platform car frame, and performing a permanent connection of the process axle with two sections of the above-mentioned groove, - allows for reliable fixation of the process axle in the folding base. As a result, in the patented utility model, deformation is reduced and the reliability of the device for fastening a container on a platform car is increased.

Based on the above, it can be concluded that the set of essential features of the claimed utility model has a causal relationship with the achieved technical result, which made it possible to solve the technical problem.

A pilot batch of a device for securing a container on a platform wagon, proposed for patenting, was manufactured, which underwent pilot work and confirmed its advantages.

Example of implementation.

The device for securing a container on a flat car comprises a folding base with a projection, contains a limiter and is installed using a process axis on the frame of the flat car. The process axis is located in an L-shaped groove made in the end wall of the folding base, the most distant from the longitudinal axis of the frame of the flat car. The process axis is inseparably connected to two sections of the groove using welding.
