Abstract

FIELD: transportation.

SUBSTANCE: invention relates to railway transport, in particular to high-speed flat wagons for transportation of freight containers. Carrier frame of high-speed wagon is made of longitudinal backbone that unites two end parts. Spinal beam consists of two Z-shaped profiles longitudinally welded to each other, reinforced in the central part from above by a horizontal sheet, and from sides – by vertical walls connected with each other and spinal beam. Inside the ridge beam, transverse partitions are located at the same distance from each other, and at the ends of the ridge beam stops of automatic coupling equipment is arranged transmitting to the frame traction and braking forces. Each end part of the frame is formed by shortened side beams from square tubes, arranged parallel to the ridge beam and connected to it by means of a frontal beam, intermediate pivot beams and two horizontal braces, diagonally located at an acute angle to the spinal beam. On the shortened side beams opposite to fittings stops, there are locking pivots additionally installed in vertical plane for fastening the container, and there are hinged locking devices in form of pivoting brackets arranged on the spinal beam on the end parts of the frame. Removable side closures of subframe equipment are installed on both sides of the spinal beam central part.

EFFECT: technical result of the invention is to improve safety of transportation by providing additional safety fixation of container to the frame of a high-speed wagon platform and its equipment with folding locking devices.

Description

The invention relates to railway transport, in particular to high-speed wagon-platforms for the transportation of large containers.

Known railway platform for transporting containers containing a chassis, a brake system and a supporting frame, which includes a spinal beam made of two I-beams of variable cross-section, side, pivot, frontal, transverse and intermediate beams, while between the frontal and pivot beams are installed braces, moreover, tipping brackets are mounted on the side beams, and fixed stops for installing containers on the frontal beams, the I-beams of the spinal beam are made with cuts along the axis of symmetry and rigidly with interconnected by means of inserts made of perforated sheets rigidly interconnected by a patent for utility model No. 50495, IPC V6ShZ / 20, publ. January 20, 2006).

The disadvantages of the known railway platform for transporting containers is the lack of additional safety fixation of the lower fittings of the container to the frame of the platform, the absence of safety locking devices to prevent entry into the container.

The technical result of the invention is to increase the safety of transportation, which is achieved by providing additional safety fixation of the container to the supporting frame of the high-speed platform car, equipping the high-speed car of the platform with folding locking devices to prevent penetration into the container, and reducing stresses arising in the supporting frame during the passage of curved sections of the track.

The specified technical result is achieved in that in a high-speed car-platform for transportation of large containers, including a supporting frame, chassis, brake system, coupler equipment, the supporting frame is made of a longitudinal spinal beam that combines two end parts, and the spinal beam consists of longitudinally welded between themselves two 2-shaped profiles, reinforced in the central part from above by a horizontal sheet, and from the sides - by vertical walls connected with each other and with the spinal beam, inside the ridge the crossbeam at the same distance from each other there are transverse partitions that increase the rigidity of the spinal beam, at the ends of the spinal beam there are stops of coupler equipment that transmit traction and braking forces to the frame, and each end part of the frame is formed by shortened side beams of square pipes parallel to each other spinal beam and connected to it by the frontal, intermediate, pivot beams and two horizontal brace beams located at an acute angle to the ridge on the shortened side beams opposite the stops of the fittings, additionally mounted rotary clamps for fixing the container are mounted in the vertical plane, and on the spinal beam in the end parts of the supporting frame there are hinged locking devices in the form of pivoting brackets, removable side closures are installed on both sides of the central part of the spinal beam subframe equipment.

The claimed technical solution is illustrated by the drawings:

FIG. 1 - high-speed platform car, side view;

figure 2 - frame high-speed wagon platform, top view;

A high-speed platform car for transportation of large containers (Fig. 1,2) includes a supporting frame 1, chassis 2, brake system 3, coupler equipment 4. The carrier frame 1 of the high-speed platform car is made of a longitudinal spinal beam 5, combining two end parts 6, and the spinal beam 5 consists of two 2-shaped profiles longitudinally welded together, reinforced in the central part from above by a horizontal sheet 7, and with vertical sides 8 connected to each other and to the spinal beam 5. Inside the spinal beam 5 at the same distance from each other are transverse partitions 9 (Fig. 3), which increase the rigidity of the spinal beam 5. At the ends of the spinal beam 5 there are stops of automatic coupler equipment (not shown) that transmit traction and braking forces to the supporting frame 1. Each end part 6 of the supporting frame 1 is formed (Fig. 2) by shortened side beams 10 of square tubes located parallel to the spinal beam 5 and connected to it by the frontal 11, intermediate 12, pivot 13 of the beams and two horizontal braces 14, located at an acute angle to the spinal beam 5. On the shortened side beams 10 opposite the stops of the fittings 15, latches 16 for vertically securing the container are additionally installed in the vertical plane, and on the spinal beam 5 in the end parts 6 of the carrier ama 1 mounted hinged locking device 17 as a rotary bracket. On both sides of the central part of the spinal beam 5, removable lateral closures 18 of the subframe equipment are installed.

High-speed platform car for the transportation of large containers works as follows.

The container is mounted on a supporting frame, which is supported by a running gear, which consists of two biaxial bogies with two-stage spring suspension. The container is kept from the overturning forces arising during operation by rotary locks additionally installed on the shortened side beams. Hinged locking devices in the form of pivoting brackets mounted on the end parts of the supporting frame are rotated and block access to the container under the influence of the weight of the lowered container. The supporting frame of the high-speed platform car is made of a longitudinal spinal beam uniting two end parts, and the spinal beam consists of two b- shaped profiles longitudinally welded together, which are reinforced in the central part from above by a horizontal sheet, and from the sides by vertical walls connected between themselves and with the spinal beam. To reduce stresses in the carrier frame of the high-speed platform car, each end part of the carrier frame is formed by shortened side beams of square tubes located parallel to the spinal beam and connected to it by the frontal, intermediate, pivot beams and two horizontal brace beams located at an acute angle to the spinal beam. To increase rigidity, transverse partitions are located inside the spinal beam at the same distance from each other. Traction and braking forces are transmitted through the stops of the coupler equipment at the ends of the spinal beam. Removable side closures installed on both sides in the central part of the spinal beam provide protection for the subframe.

The use of the inventive high-speed platform car for the transportation of standard containers of various sizes is intended.
