Description

    ..

The invention relates to railway transport and can be used for the carriage of goods in transport packages on a railway platform.

A device for securing goods on a transport platform is known, which comprises fixed adjustable supports that are mounted on the platform by means of locking pins installed in the sockets and have horizontal platforms for the cargo with rigid, mutually perpendicular vertical restraints 1.

The disadvantage of this device is that the transportation of cargo packages without rigid containers on such devices is impossible, because the adjustable stops are designed only for the perception of horizontal cutting forces, resulting in a fixed load, which can lead to the destruction of dupacko. bath in a rigid container of a cargo and a vytorachivaniye of an emphasis from nests. .

The purpose of the invention is to improve the operational reliability of the device when transporting packages of sheet metal and ensuring the safety of the latter by quenching the validity of the device. on the elements of inertial loads

This goal is achieved by “supporting protrusions on the platforms of the said stops, for the load, the fixing pins are placed on the back-supports, and the slots for them are made in the platform, and the distance from the support protrusion of each stop to the limiting rack, perpendicular real longitudinal (the platform axis is determined by the formula

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same plan; in fig. 3 - the same, side view; in fig. 4-average rack, accoJ ometer; FIG. 5 - side stand, axonometric; in fig. 6 is a section A-A in FIG. 2. On the transport platform 1, the frame 2 is freely mounted with the latches 3 which are integral with it on its lower plane. In the upper plane of the frame (platform) along the longitudinal axis, slots 4 are made, extending along the entire length. On the upper plane of the frame are persustavnye stops :, end 5, side 6 (Fig. 5) and middle 7 (Fig. 4). Each of the lugs consists of a limiting rack 8, a horizontal platform 9 and a restrictive rack 10. On the lower plane of the platform 9, there are placed fixing pins 11, which enter the sockets 4 of the frame 2 and are in contact with 1 wide working ends 12. On the upper plane of the platform 9 there are fixed supporting the protrusions 13 on which the cargo packages are stacked 14. When the rolling stock collides or brakes, the horizontal forces of inertia of the cargo are transmitted along the entire plane of contact to the limiting post 8, and their resultant, coincident in height e with the center of gravity of the package, tends to turn the rack in the direction of these forces. At the same time, in the opposite direction, through the support lug 13, the force of the weight of the load is applied to each rack. The inertia forces of the load are transmitted through the limiting post 8, the platform 9, the working end 12 of the pin AND entering the socket to 4 on the frame 2, and the frame 2 through its fixture 3 transmits the force to the platform 1. The frame of the device works only on the compression force which makes it possible not to bind it rigidly with the platform frame, which results in lightening its weight and making it possible to carry it out to increase the cargo capacity across the width of the rolling stock. The distance I from the supporting protrusion of each adjustable stop to the limiting post 8 is determined by the formula I aH, where a is the specific force of the longitudinal inertial force; H - the height of the center of the body of cargo to the upper plane of the transport platform. This ratio is constant when calculating cargo securing for open rolling stock of railway transport. This ratio is true for any type and weight of the cargo being transported and depends only on its overall dimensions. The proposed device secures goods, such as asbestos-cement, metal, wood-fiber, synthetic and other sheets, without any means of fastening in the transport package and reliably secures the entire set of packages on the railway platform without using any fastening materials and ensures their safety during transportation. The specified device is suitable for the transport of containers and cargo in rigid containers. The invention of the Device for securing goods on a transport platform, containing fixed on the platform by means of fixing pins installed in the nest, adjustable stops, having horizontal platforms before the cargo with rigidly perpendicular vertical mutually permissible limiting posts, e with the fact that, in order to increase the operational reliability of the device during the transport of packages of sheet material and to ensure the safety of the latter, elements of the inertial load device, support protrusions for the load are fixed on the platforms of the said stops; , is determined by the formula G aH, where a is the specific value of the longitudinal inertial force; H is the height from the center of the body of cargo to the upper plane of the transport platform.
