Description

The proposed technical solution relates to the field of railway transport, in particular, to signals and road signs.

Currently, in accordance with the requirements of the “Instructions for signaling on the railways of the Russian Federation” dated 05.25.2000, TsRB-757, as amended and supplemented, Order of the Ministry of Railways of the Russian Federation of July 3, 2001 No. 16, and dated May 27, 2002 No. 24, paragraph 7.5. - “Tail” of a train when driving on single-track and on the right and wrong paths on double-track sections is indicated:

freight and cargo-passenger (day and night) - a red disk (hereinafter referred to as the "Disk") with a reflector (or retroreflector) at the buffer beam on the right side "(meaning the buffer beam of the tail of the train).

The shape of the “Disk” and its relative size are determined by Figure 7.3.a. this instruction.

Regulatory documents: GOST 8442-65 “Signs of track and signal railways” and Order No. 9-TsZ of July 3, 1991 of the Ministry of Railways of the Russian Federation “On the design of typical permanent disks for speed reduction, portable signals, signal and way signs”, information about the “Disk »Tail wagon and technical requirements for its design do not contain.

For fastening the "Disc", each freight car has a special bracket from two ends, welded to the buffer bars on the right side (Figure 1).

Because. that the normative and design documentation for the “Disc” of the tail carriage of a train is absent, it is found in

At present, the design is as follows: it is a metal disk of a circular shape with a diameter of 150 to 200 mm (maybe more), where on one side the rim is applied with white paint along the edge of the circle, and in the center of the disk with a diameter of 130-180 mm a red circle is reflective (retroreflective) paint, on the other side of the disk, a curved-shaped metal plate is welded parallel to its surface, allowing it to be inserted into a special opening (1) of a standard bracket (Figure 1), welded to the buffer beam of the car.

The disadvantage of this design is that the metal plate in the bracket holds the “Disc” only from lateral displacements and from vertical displacement downward, and from vertical displacement upward with strong rolling or shaking of wagons during movement of a freight train may not hold in all cases, therefore, the disk can jump out and get lost along the route, which in turn can lead to emergency situations on the railway in certain situations. Also, due to the fact that the “Disks” are often lost, to signal the tail carriage of the train at the stations, homemade disks are made of improvised material (cans, pieces of sheet metal painted with red paint of any geometric shape) and wire, which again cannot ensure 100% deduction of such a “home-made” “Disc” in the bracket of the car while the car is moving on the train.

The retroreflective composition of the self-adhesive film, as well as the red and white colors, allows you to see this device at a certain distance, both as a locomotive brigade after a running train or locomotive, and to control the integrity of the train in the presence of this disk on the tail carriage on duty at the railway crossing and on duty at the stations.

The absence of a “Disk” (of any geometric shape and size) indicates a special situation regarding the presence of all the cars in the train and makes it necessary to reconcile the actual number of cars by their numbers with the full-size sheet of the train.

On stretches of double-track sections, the duty to control the integrity of the train by the presence of a “Disc” on the tail car is assigned to the locomotive brigade of the oncoming train.

The proposed technical solutions make it possible to ensure the maximum possible visibility and readability of the signal device of the tail carriage as a signal responsible for the safety of train traffic, as well as to ensure the reliability of the fastening of this device to the existing standard fixture (bracket) on all types of cars of the freight fleet of the Russian Federation and CIS countries .

The signal device is made of sheet metal or plastic by stamping or casting, mainly in the form of a circle having a wide (from 5 to 20% of the circle radius) rim (2) along the outer contour and a convex surface (3) on the outer surface (Figure 2) in the shape of a circle of the rest of the central part.

A reflective (retroreflective) coating, for example, white, is applied to the outside of the device along the rim, and a reflective (retroreflective) coating, for example, red in the shape of a circle, is applied over the central convex part over the entire surface.

A surface of this shape with a convex central part allows for the highest possible visibility, including and at different viewing angles and the readability of the signal device when the train is moving or standing, compared to a flat surface. The inner surface of the signal device has a mounting part, which consists of:

- from the main metal or plastic plate - brackets (4) with a semicircular emphasis (5) and the elongated part - handles (6), the width of the main metal or plastic plate - brackets should correspond to the internal width of the opening of a typical car bracket intended for mounting the device;

- from a springy metal or plastic plate (7) with a semicircular stop (8) attached (welded or cast from the main) to the main plate from the inside of its lower part.

The proposed design of the mounting of the alarm device operates as follows:

- for the convenience of workers, when carrying the signal device to the tail carriage of the train, at an average distance of about 1 km, especially in winter, in thick warm gauntlets, an elongated part is provided - handle (6), which when fastening the device, being part of the main metal or plastic plate - staples (4) is inserted into a special opening (1) of a typical staple of a car (Figure 1). Further, when you press the top of the device down until it clicks, the stop (5) is pressed under the bottom of the inner side of the opening, as if clinging to it, due to the force arising from the compression of a springy metal or plastic plate (6) between the main metal (plastic ) by a plate - a bracket (4) and the opposite inner side of the opening (1).

The emphasis of the main metal plate-brackets (5) and the emphasis of the springy metal plate (8) in the profile are in the form of a semicircle to provide more free sliding on the inner surfaces of the standard bracket of the car (1) during insertion and removal.

The device is removed by pressing the lower part of the handle (6) of the main metal plate - the brackets on itself and upward, while the springy plate (7) is compressed, the stop (5) disengages from the standard bracket of the car (Figure 1) and enters aperture (1), then the device is removed by pulling upward towards the upper part.

Thus, the problem is solved of eliminating the possibility of displacement of the mounting of the signal device in the vertical direction upwards, and accordingly in all directions, which will ensure the reliability of its fastening to the standard bracket of the car while the train is moving,

simplicity and convenience in the actions of workers when carrying, attaching and removing the alarm device.

Alternatively, the mounting of the signaling device can be made with a springy metal plate (7) located on the outside of the main metal plate (Figure 3).

Alternatively, the mounting of the signaling device can be made on the principle of any end of the “clothespin” with a spring located along the surface of the signaling device (Figure 4) and across the surface of the device (Figure No. 5).

Alternatively, the outer side of the signaling device, in order to improve reflective (retroreflective) properties, can be made with reflectors made of plastic or glass, in particular by spraying.

Alternatively, the external side of the signal device with reflectors, in order to increase the efficiency of the signal at night, can be equipped with LEDs or other light sources operating from batteries, rechargeable batteries, solar panels or other energy sources with forced, autonomous or automatic switching on and off.

Alternatively, the design of the signaling device can be performed by the national team, i.e. from different materials, the features of which and their manufacturability allows to achieve a higher quality of the design of the disk, its long service life, including from composite or reinforced materials.

Alternatively, a signal device, being a sign of a certain signal, can be made in the form of any geometric shape (square, rectangle, triangle, circle, etc.), as well as in any type of cross section, depending on requirements

regulatory organizations that determine the design, its features and the operation of this signal.

Alternatively, the paint or self-adhesive film on the disk may be light-accumulating, photoluminescent, etc.

As an option for attaching a signal device to a car, a magnet, adhesive tape, etc. can be used.

Alternatively, glass or polymer balls, pyramids, etc. may be used in the reflective surface of the device.

In addition, in accordance with certain conditions of application and use of the signal device, the color of its surfaces and shape can be changed.

In figures 2,3,4.5 presents a preferred view (with options) of the proposed signal device, which does not limit the possibility of another equivalent execution of the device.
