Description

The utility model relates to rail vehicles, in particular to railway cargo platforms for the transportation of large-capacity containers.

A well-known wagon-platform for transportation of large-capacity containers, containing a frame mounted on undercarriages with end beams, on which latches are installed to prevent opening of the end doors of large-capacity containers during their transportation on the frame, while the latches-stops are made in the form of movable along their longitudinal axis and spring-loaded guide pins installed in the guide housings (RU 208957, B61D 3/08, publ. 01/24/2022 (prototype)).

The technical problem inherent in this platform car is its low operational efficiency and low reliability, caused by the need for accurate orientation of large-capacity containers when lowering large-capacity containers onto the frame of the platform car between the clamps, which are vertical fingers, and the inoperability of the clamps in the event of a break or loss elastic properties of compression springs, providing elastic mobility of vertical fingers and operability of clamps.

The technical result of the claimed utility model is to increase the operational efficiency and reliability of the platform car for the transportation of large-capacity containers.

The specified technical result is provided by a platform car for the transportation of large-capacity containers, containing a frame installed on the undercarriage with end beams, on which clamps are installed to prevent opening of the end doors of large-capacity containers during their transportation on the frame, each of the clamps is made L-shaped with a drive and with thrust arms and pivotally mounted on an axis mounted on the end beam of the frame, the drive arm of the latch is designed to be placed under the bottom of a large-capacity container and interact with it, the thrust arm of the latch is designed to prevent the opening of the end door of a large-capacity container when it is installed on the frame, while the center of mass The L-shaped latch is located with an offset from the axis of its hinge in the direction from the end beam for the purpose of spontaneous rotation of the L-shaped latch when its drive arm is released from interaction with the bottom of the large-capacity container; the thrust arm of the L-shaped latch can be made with a lower end protruding below the hinge axis, which is used as a stop for the L-shaped latch in the non-working position; L-shaped stops can be equipped with stiffeners; the thrust arm of the L-shaped stops can be made with a guide bend to guide the bottom of the large-capacity container when it is installed on the frame.

The claimed utility model differs from the prototype in that each of the latches is L-shaped with drive and thrust arms and is pivotally mounted on an axis mounted on the end beam of the frame, the drive arm of the latch is designed to be placed under the bottom of a large-tonnage container and interact with it, thrust the latch arm is designed to prevent the opening of the end door of a large-tonnage container when it is installed on the frame, while the center of mass of the L-shaped latch is located with an offset from the axis of its hinge in the direction from the end beam in order to spontaneously rotate the L-shaped latch when its drive arm is released from interaction with the bottom of a large-capacity container; the thrust arm of the L-shaped latch is made with a lower end protruding below the hinge axis, which is used as a stop for the L-shaped latch in the non-working position; L-shaped stops are equipped with stiffeners; the thrust arm of the L-shaped stops is made with a guide bend to guide the bottom of the large-capacity container when it is installed on the frame.

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 platform car for the transportation of large-capacity containers 1 (Fig. 1, 2) contains a frame 3 installed on the undercarriage 2 with end beams 3.1. On the end beams 3.1, latches are installed to prevent the opening of the end doors 1.1 of large-capacity containers 1 during their transportation on the frame 3.

Each of the clamps is made in the form of an L-shaped clamp 4, mounted on the end beam 3.1 of the frame 3, pivotally mounted on the axis 4.3 (Fig. 3, 4). and interaction with it (Fig. 5, 6). The thrust arm 4.2 of the L-shaped latch 4 is intended for fixing the end door 1.1 of the large-tonnage container 1 when it is installed on the frame 3. The L-shaped latch 4 is designed in such a way that the center of their mass is located offset from the axis 4.3 of the hinge of the L-shaped latch 4 in direction from the end beam 3.1 for the purpose of spontaneous rotation of the L-shaped latch 4 into the open non-working position when its lower drive arm 4.1 is released from interaction with the bottom 1.2 of the large-capacity container 1. In the open non-working position of the L-shaped latch, its drive 4.1 and thrust 4.2 shoulders are located inclined relative to the horizontal.

The thrust arm 4.2 of the L-shaped latch can be made with the lower end 4.4 protruding below the axis 4.3 of the hinge of the L-shaped latch 4, used as a stop of the L-shaped latch 4 in the non-working position in the front plate of the end beam 3.1. To increase wear resistance and strength, L-shaped clamps 4 can be equipped with stiffeners 4.5.

The thrust arm 4.2 of the L-shaped clamps 4 can be made with a guide bend 4.6 to facilitate the direction of the bottom 1.2 of the large-tonnage container 1 when it is lowered onto the frame 3.

The utility model is used as follows.

In the non-working position of the L-shaped clamps 4, their drive 4.1 and thrust 4.2 shoulders are in an inclined position. Large-capacity containers 1 are lowered onto the frame 3 of the platform car. The bottom 1.2 of the large-capacity container 1, acting on the drive arm 4.1, rotates the L-shaped stop 4 on the hinge axis 4.3 and moves it to the closed operating position. In this case, the drive arm 4.1 is placed under the bottom 1.2 and interacts with it, the thrust arm 4.2 occupies a vertical position and prevents the opening of the end door 1.1 of the large-capacity container 1. When unloading the platform car, the large-capacity containers 1 are lifted from the frame 3, the L-shaped stops 4 under the action of their displaced center of mass are rotated on the axis 4.3 of the hinge in the opposite direction, occupying an open non-working position with their protruding lower end 4.4 resting against the front plate of the end beam 3.1 of the frame 3.

The implementation of L-shaped stops 4 pivotally mounted on the frame 3 and occupying an open non-working position on an empty platform car, when the upper edges of the thrust arm 4.2 form a horizontal loading area increased in their longitudinal dimensions, facilitates the orientation of large-capacity containers 1 when they are lowered onto the frame and provides while fixing the end doors 1.1 with a thrust shoulder 4.2 of the end doors 1.1 of large-capacity containers 1, it does not require the use of compression springs that reduce the reliability of the latches. This design of the end door latches 1.1 increases the operational efficiency and reliability of the use of the platform car.
