RU2767081C1 - Flat car for the transportation of containerized freight - Google Patents

Abstract

FIELD: railway transport.

SUBSTANCE: invention relates to the field of railway transport, in particular to freight cars intended for the transportation of containerized freight. A containerized freight flat car contains two automatic coupling devices (1) and braking equipment (2), running gear (3), on which the supporting frame (4) with stationary (5) and folding (6) fitting stops rests. The end beam of the frame is made of vertical and horizontal sheets, the side beams have upper and lower horizontal belts connected by a diaphragm. The upper horizontal belt of each of the side beams is made protruding along the length beyond the end beams, has chamfers on the end parts and is rigidly connected to the vertical sheets of the end beams by means of brackets formed by an edge in the form of a right triangle covered from the end with an overlay, on which the extreme pairs of stationary fitting stops rest.

EFFECT: expansion of the range of solutions for container rail shipments.

Description

The invention relates to the field of railway transport, in particular to freight cars intended for the carriage of container-type goods.

A railway car frame is known - a platform for the transportation of large-capacity containers, which includes a carrier beam, side, pivot, transverse and frontal beams, as well as folding and stationary fitting stops (patent RU No. platform", B61F 1/00, B61D 3/20, B60P 7/13).

The disadvantages of the prototype include the presence of a weld at the junction of the base plate and the upper horizontal chord of the side beam, which is a stress concentrator, which reduces the reliability of the structure as a whole, and the need to use special bench equipment to install the base plate flush with the plane of the upper horizontal chord of the side beam, which significantly increases the cost of assembling the car frame.

The objective of the invention is to create a wagon - a platform of equal strength design with reduced metal consumption, as well as a safer and simplified procedure for maintenance and repair.

The technical result of the claimed invention is to provide the possibility of transporting a wide range of container-type cargo, reducing the metal consumption, increasing the carrying capacity, manufacturability and safety of the structure.

This technical result is achieved by the fact that the wagon-platform for the carriage of goods of a container type, containing automatic coupling and braking equipment, based on the chassis of the carrier frame with stationary and folding fitting stops, the end beam of which is made of vertical and horizontal sheets, the side beams have an upper and the lower horizontal chords connected by a diaphragm, according to the invention, the upper horizontal chord of each of the side beams is made protruding along the length of the platform car beyond the end beams, has chamfers on the end parts and is rigidly connected to the vertical sheets of the end beams using brackets formed by a rib in the form a right-angled triangle, sewn at the end with an overlay, on which the extreme pairs of stationary fitting stops rest.

The protrusion of the upper horizontal chords of the side beams beyond the end beams during the manufacture of the wagon-platform eliminates the presence of additional welds in the area of the installation plane of the extreme fitting stops, which increases the manufacturability of the design and ensures the same margin of safety along the entire length of the chords. The presence of one bracket, formed by a rib in the form of a right-angled triangle, sewn at the end with an overlay, simplifies the procedure for maintenance and repair of the platform car. The absence of sharp edges due to the presence of chamfers in the end part of the upper horizontal belts of the side beams and the lining on the bracket rib increases the safety of the product design.

The invention is illustrated by drawings, which do not cover and, moreover, do not limit the entire scope of claims of this technical solution, but are only illustrative materials of a particular case of execution:

in fig. 1 - wagon platform for container-type cargo;

in fig. 2 - wagon platform for container-type cargo, view A;

A wagon is claimed - a platform for the carriage of container-type goods, containing two automatic couplers 1 (Fig. 1) and brake equipment 2 (Fig. 1), chassis 3 (Fig. 1), on which the supporting frame 4 (Fig. 1) rests with stationary 5 (Fig. 1, Fig. 2) and folding 6 (Fig. 1) fitting stops. The end beam 7 (Fig. 2) of the frame consists of vertical 8 (Fig. 2) and horizontal 9 (Fig. 2) sheets, side beams 10 (Fig. 2) have an upper 11 (Fig. 2) and a lower 12 (Fig. 2) horizontal belts connected by a diaphragm 13 (Fig. 2). The upper horizontal belt 11 (Fig. 2) of each of the side beams 10 (Fig. 2) is made protruding along the length beyond the end beams 7 (Fig. 2), has chamfers 14 on the end parts (Fig. 2) and is rigidly connected to the vertical sheets of end beams 8 (Fig. 2) using brackets 15 (Fig. 2) formed by a rib in the form of a right-angled triangle, sewn at the end with an overlay 16 (Fig. 2), on which the extreme pairs of stationary fitting stops 5 (Fig. 1) are supported , Fig. 2).

The set of essential features of the invention makes it possible to create a platform car for transporting a wide range of container-type cargo, including large-capacity containers, tank containers, SWAP containers, containers with autonomous diesel generator sets and other specialized containers and other cargo having fittings that do not require protection from direct exposure to atmospheric precipitation without increasing the overall dimensions of the frame, with a more robust design, as well as with a more convenient and safer maintenance and repair procedure.
