Abstract

The utility model relates to the field of railway transport, in particular, to signals and signs, attached to typical rail brackets as a signal device of a tail car, as a signal responsible for the safety of trains. The technical result of the utility model is the universal possibility of simple and reliable signal mounting devices with wire to the details of any car, if there is no standard bracket on the car for regular mounting of the signaling device. This allows, in turn, to put cars without a standard bracket at the tail of the train and not to look for special signaling devices for them, which reduces shunting work when the train is formed (including electric trains inoperative when the cars are delivered directly from the factory). In addition, it is possible to carry more signaling devices in one hand than in the prototype and a more convenient carrying process. It also provides the ability to store multiple signaling devices of the same type on a wall pin or nail, without the need for storage to use sections on shelves or in a cabinet ( there is no need to occupy space during storage of devices). The above technical result is achieved by the fact that a universal signaling device for cargo tail is stated a, which is a surface, on the front of which a reflective coating of at least two colors is applied, the internal surface of the device has a fastening part, which consists of a main plate - a bracket with an emphasis and an elongated part - a handle, and from an internal plate the sides of its lower part of the spring plate with an emphasis, characterized in that a through hole with a diameter of at least 1 mm is made in the handle.

Description

The utility model relates to the field of railway transport, in particular, to signals and road signs, which are attached to railroad car brackets as a signal device for a tail car, as a signal responsible for the safety of train traffic.

Currently, in accordance with the requirements of paragraph 88 of the “Instructions for Signaling on Railways of the Russian Federation”, Appendix No. 7 to the Rules for the Technical Operation of Railways, introduced by Order of the Ministry of Transport of Russia No. 162 of 04.06.2012. - “The“ tail ”of a train when moving on single-track and on the right and wrong railway track on double-track sections is designated:“ cargo and cargo-passenger (day and night) - with a red disc (hereinafter “Disc”) with a reflector (or retro-reflector) buffer bar on the right side ”(meaning the buffer bar of the train tail car). Also, in accordance with the same paragraph 88, the red disc indicates the head of the train when moving cars forward. The “Disc” form, its relative size and placement on the wagon are determined by figures 192 and 195 of this instruction. Normative documents: GOST 8442-65 "Signs for travel and signal railways" and Order No. 9-CH from July 3, 1991, of the Ministry of Railways of the Russian Federation "On the design of typical permanent speed reduction disks, portable signals, signal and road signs", information about "Disk "Tail wagon and technical requirements for its design does not contain. For mounting the “Disc”, each freight car with two ends of the structure has a special standard bracket welded to the buffer bars on the right side. When marking the head of a train when moving cars forward in accordance with the requirements of paragraph 88 of Figure 195 of the above Instruction, the red disk should be placed on the right in the direction of travel, i.e. on the left side of the buffer bar, where there is no special standard mounting bracket. Also, this type of bracket is missing for postal baggage and passenger cars. When these cars are turned on in freight, modular and transfer trains there is no possibility of secure attachment of the signaling device at the end of the car (due to the absence of a cramp).

In practice, the design of such a sign “Disk” has long been used. It is a metal disk of a round shape, where on the one hand a white reflective (retroreflective) rim is applied around the circumference, and a reflective (retroreflective) red color is applied in the center of the disk On the other side of the disk, a metal plate of a curved shape is welded parallel to its surface, allowing it to be inserted into a special opening of a typical bracket welded to the buffer bar of the car.

But with such a design, the metal plate in the bracket keeps the “Disc” only from lateral displacements and from vertical displacement downwards, and from vertical displacement upwards during strong rolling or shaking of cars while the freight train is moving, it may not hold in all cases, therefore the disc may pop out get lost on the way, which in turn can in certain situations lead to an emergency on the railway. Due to the fact that the “Disks” are often lost, the station workers are forced to attach self-made disks made of improvised material to signal the train's tail car, which also cannot ensure reliable retention of such “homemade” “Disk” in a typical tail carriage during movement in the train.

The retroreflective properties of the self-adhesive film used on the disk, or the paints of red and white colors make it possible to see this device at a certain distance in the daytime and at night, as the locomotive brigade follows a train or locomotive and controls the integrity of the train if this disc is on the tail car on duty railway crossing and on duty stations.

Known signaling devices: (RU 76882, B61K 13/00, published on 10.10.2008; RU 143623 U, published on 07/27/2014.)

The technical solution of patent RU 143623 U describes a signal device for a railway car, which is a metal or plastic surface in the form of a circle, on the front of which a layer of reflective or retroreflective coating is placed with graphic symbols placed on it or in it, at least two colors, on the back of the circle is placed a vertically oriented plate, located at a distance from the back of the circle, and one end of which is attached to the upper hour This circle and the other end is located below the lower edge of the circle. At the same time, a concavity is made on the plate opposite the back side of the circle to accommodate a typical railroad carriage bracket, and a springy plate attached to the plate in the space between the back side of the circle and the plate itself, and the other end of which is installed with emphasis in the back side of the circle, characterized in that the metal or plastic surface in the form of a circle is made flat, concavity to accommodate a typical rail brace The fixed car is located opposite the central part of the rear surface of the circle, and the spring plate is attached to the plate by two fasteners located at a distance from each other in height and in the horizontal direction, which are located on the plate below the concavity and above the lower edge of the circle, and on the back section the surface of the circle is made with a flat and straight end, bent to the side of the plate for the formation of an emphasis in a circle in the inflection zone.

Also described is a signal device for a railroad car, which is a metal surface in the form of a circle, on the front of which there is a reflective or retroreflective coating layer with graphic symbols placed on it or in it composed of at least two colors, placed vertically on the back side of the circle oriented plate, located at a distance from the back side of the circle, and one end of which is attached to the upper part of the circle, and the other end is located below the lower edge and a circle, while on the plate opposite the back side of the circle there is a concavity to accommodate a typical railroad carriage, and a springy plate attached to the plate with one end placed in the space between the back side of the circle and the plate itself, and the other end of which is installed with an emphasis to the back circle, characterized in that the metal surface in the form of a circle is made flat, the concavity to accommodate a typical railroad carriage is located opposite the central part of the rear top spines of a circle, and a springy plate is attached to the plate by two rivets spaced apart from each other in height and in the horizontal direction, which are located on the plate below the concavity and above the lower edge of the circle, and in the section of the abutment into the back surface of the circle are made with a flat and straight end , bent to the side of the plate for the formation of an abutment in a circle in the inflection zone, and the said coating on the circle is a layer of ground silicate enamel on which a layer of surface silicate enamel is laid, bearing a graph tahmic symbolism caused by melted ceramic dyes by silk screen printing.

In another technical solution RU 76882 U, B61K 13/00, publ. 10.10.2008., Adopted for the prototype, a signaling device is described, which is a metal or plastic surface with a narrow rim along the outer contour and a convex part of the rest of the central part, the outer side of the surface along the rim contains a reflective (retroreflective) coating of the desired color, and the central convex part over the entire surface - a reflective (retroreflective) coating of another desired color; the inner surface of the device has a fastening part, which consists of the main Allic or plastic plate - brackets with a semicircular stop and an elongated part - handles, the width of the main metal or plastic plate - the bracket should correspond to the internal width of the opening of a typical car bracket designed for mounting the device and from the lower part attached to the main plate from the inner side metal or plastic plate with a semicircular stop (RU 76882, B61K 13/00, publ. 10.10.2008).

The technical problem of the prototype and other analogue is the inconvenience of carrying the signal device disks in the process of hanging onto the tail or head cars of trains. It is inconvenient to hold the device by the hand with the hand, since the thin edges of the handle cut into the palm of the hand. And when wearing devices, it is also inconvenient to carry the glove, because you need to carry the disc upwards so that the handle does not slip out of the glove under the weight of the disc, especially in the frosty season. As a result, it is inconvenient to carry even 2 devices, and to carry a larger amount you need to use a bag.

In addition, there is the difficulty of reliably attaching signaling devices in the appropriate place of the buffer bar of the car, in cases of damage or lack of a standard cramp on the freight car for regular disc mounting. Also, the typical mounting bracket is missing for postal baggage and passenger cars. When these cars are turned on in freight, modular and transfer trains, there is no possibility of regular attachment of a signal device at the end of the car (due to the absence of a cramp). Therefore, this device cannot be reliably fixed on the cars without a bracket, which does not allow to put the specified cars into the tail of the train or it is required to look for special signaling devices for them. These problems increase shunting during train formation.

Also difficult to store signaling devices. Storage requires a capacity or section on a shelf or in a closet.

The task of the utility model is to eliminate the technical problems of the known solutions.

The technical result of the utility model is the ability to carry a larger number of signaling devices in one hand than in the prototype and a more convenient carrying process. In addition, it is possible to simply and securely attach the signaling device with a wire to the details of any carriage, in the absence of a typical cradle on the carriage for regular attachment of the signaling device. This allows, in turn, to put cars without shackles in the train host and not to look for special signaling devices for them, which reduces shunting work during train formation. It also provides the ability to store a variety of similar signaling devices on a wall pin or nail, without the need for storage to use sections on shelves or in a cabinet (that is, it is required to occupy smaller floor space when storing devices).

This technical result is achieved by the fact that the declared universal signaling device for the tail of a freight train, which is a surface, on the front of which a reflective coating is applied in at least two colors, the inner surface of the device has a fixing part, which consists of a main plate - bracket with an emphasis and the elongated part - the handle, and from the spring plate attached to the main plate on the inner side of its lower part with an emphasis, characterized in that the handle has a squash Hot hole with a diameter of at least 1 mm.

The utility model is illustrated in the drawing (Fig. 1).

In the drawing: 1 - a through hole, 2 - a rim of a reflecting surface, 3 - a central portion of a reflecting surface, 4 - a main plate-clip, 5 - an emphasis of the main plate bracket, 6 - a handle, 7 - a spring plate, 8 - an emphasis of a spring plate .

Implementation of the utility model

The signaling device (see drawing in Fig. 1) can be made from sheet metal or plastic by stamping or casting. The 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 the requirements. A reflective (retroreflective) coating, such as white, is applied to the outside of the device, and a reflective (retroreflective) coating, such as red, is applied to the central part over the entire surface. The reflective surface allows for the highest possible visibility, incl. and from different angles of view and readability of the signal device when the train or its station is moving.

The internal surface of the alarm device has a mounting part, which consists of:

- from the main plate (can be made, for example, metal or plastic) - bracket 4 with the stop 5 and the elongated part - handle 6, the width of the main plate preferably should correspond to the internal width of the opening of the typical bracket of the car intended for fastening the device;

- from spring plate 7 (can be made, for example, metal or plastic) with a stop 8 attached (welded or cast from the main) to the main plate from the inner side of its lower part.

New is the fact that in the handle 6 is made a through hole 1 with a diameter of at least 1 mm, sufficient for pushing through this hole, such as metal wire or coupling clamp. An opening of less than 1 mm will allow only a thin wire to be missed, the fastening of which of the signal device will be unreliable due to the fact that when the car shakes in motion, the handle twitches and the edges of handle 6 can cut the wire with a thickness of less than 1 mm or cause it to break in the trough zone through hole 6.

If there are 6 holes on the handle, the signaling device can be mounted through this hole with a clamp or tie:

- to the buffer bar on the right side of the tail freight car of the train, when the type bracket is mechanically damaged during loading and unloading of the wagon;

- to the buffer bar on the left side of the head freight car when the train is moving forward in cars, when the typical bracket is absent as not provided for by the car structure;

- to the buffer devices of the postal-baggage or passenger car, electric trains, when, during technological transportation, they are out of service at the tail of a freight train. This design of the signaling device allows you to put these cars in the tail of the train and not to look for special signaling devices for them.

Thereby, shunting work during the formation of the train is reduced (when the cars are delivered directly from the factory).

The proposed mounting structure of the signal device operates as follows:

- for the convenience of workers when carrying a signal device to the tail or head car of a train, an average distance of about 1 km, especially in winter, in thick warm mittens, is provided with an elongated part - handle 6, which, when fastening the device, being part of the main plate - bracket 4 is inserted into a special aperture of a typical rail carriage. Further, when pressing the upper part of the device down until it clicks, the stop 5 is pressed under the lower part of the inner side of the opening, as if clinging to it, due to the force that occurs when compressing the spring plate 6 between the main plate - bracket 4 and the opposite inner side of the opening.

The stop 5 of the main plate - the brackets 4 and the stop 8 of the spring plate 7 in profile can have the shape of a semicircle to allow more free sliding along the internal surfaces of the typical car bracket when inserted and notched. The device is removed by pressing the lower part of the handle 6 of the main metal plate - the bracket itself and upwards, while the spring plate 7 is compressed, the stop 5 goes out of engagement with the standard carriage bracket and enters the opening, then the device is removed by pulling out the upper part along upward direction.

Thus, the problem of eliminating the possibility of mounting the signal device in the vertical direction upwards and, accordingly, in all directions is solved, which will ensure the reliability of its attachment to the standard carriage bracket while the train is moving, if there is a standard bracket on the given carriage for the standard disk mounting.

In the event that there is no typical bracket on the car for mounting the disc on the car, the possibility of simple and reliable mounting of the signaling device is carried out by a wire through the through hole 1 to the car details.

The same through hole 1 provides the possibility of carrying more signaling devices in one hand than in the prototype and a more convenient carrying process, since the diameter of hole 1 is sufficient to push the wire through it and create a bundle with many signaling devices of the same type. As a result, only one hand can carry a whole bunch of signaling devices in several units at once. In addition, the specified through hole 1 provides the ability to store at once a variety of signaling devices of the same type, both individually worn on a wall pin or nail, and in the form of the above bundle intended for carrying, without the need to use a section for storage on shelves or in a cabinet. This allows for the storage of such devices to occupy less usable floor space.
