Description

The utility model relates to the production of reinforced concrete sleepers, turnout beams and other track superstructure structures.

In accordance with GOST R 54747-2011 “Reinforced concrete sleepers for 1520 mm gauge railways. General technical conditions” and OST 32.134-99 “Reinforced concrete prestressed beams for turnouts. General technical conditions” marking (QC stamp and batch number) is applied to each finished product with indelible paint.

The disadvantage of the existing method of applying markings with paint is that after a short time (in some cases after a year) under the influence of atmospheric factors and an aggressive environment (ingress of oil, salts), the paint is erased and product identification is impossible (there is no batch number and OTK stamp). Applying the batch number and the QCD stamp (shift-change data) by stamping in concrete is labor-intensive, because requires every shift re-equipment of mold equipment.

In accordance with GOST 33320-2015, the marking of the sleepers is carried out by stamping in concrete, as well as indelible paint, while additional marking methods are allowed that ensure the identification of the sleeper during the entire service life of the sleepers.

A known method of applying identification data to a reinforced concrete sleeper or turnout beam, characterized in that the markings are applied to a polymer embedded part by hot stamping, which is monolithic in the molding process into a reinforced concrete sleeper or turnout beam at the same level with the upper surface of the product (according to the patent RU2614427, class E01B 31/20, E01B 3/28, published 03/28/17).

The text of the patent states that the cross-sectional detail may have the shape of a cone. According to figure 1, identification data is applied to the flat base of the cone, therefore, the top of the cone is located in the body of the sleeper. Such a shape and location of the embedded part does not ensure its secure fastening and may lead to falling out, which is a disadvantage of the known solution.

In addition, according to the text of the patent, a cylindrical protrusion is made on the embedded part for fastening in a form for pouring a sleeper. The protrusion of this configuration requires the exact execution of the reciprocal hole in the form to securely fasten the embedded part. This is also a disadvantage of the prototype.

In addition, as indicated in the patent, the part may have side walls of a concave or convex shape in cross section. This ensures its secure fastening in the body of the sleeper, but reduces the manufacturability of the part, which is another drawback of the prototype.

The closest technical solution is the solution of the under-rail base, where an embedded part for applying identification data to reinforced concrete sleepers and railroad switches, consisting of a body, the outer surface of which is subject to marking, and on which a bushing is located. The body has the shape of a truncated cone, the surface opposite to the base of the truncated cone is marked, and the sleeve located on it tapers in the direction from the body and, at the same time, has a triangular shape in cross section. According to the embodiment, a radio tag is installed in the recess on the body of the embedded part (according to the patent RU182274, class E01B 31/20, published on 09.08.18).

The disadvantage of the prototype is that the radio tag installed in the recess on the body is located along the edges of the sleeper, from any one edge. Thus, sleepers with marks can be located on the tracks with different ends of the sleepers in different directions. This leads to the fact that the readers, if they are on a transport rail vehicle, must be located on different sides of such a means, and if the reading is carried out manually, then it will alternately be brought to one side of the rail track, then to the other.

The technical result, which the proposed utility model is aimed at, is to provide convenient reading of the indications of the radio tag installed inside the embedded part.

The specified technical result is achieved by the fact that the under-rail base in the form of a beam contains an embedded part with a radio tag (RFID tag) for recording the identification data of reinforced concrete sleepers and turnout beams, while the embedded part consists of a body with a cover and is located in the area of the middle part (central zone ) beam, where the middle part is understood as one third of the total length of the beam, located between the two extreme parts, also constituting one third each. This can also be explained as follows: the embedded part is located in the middle part of the base, that is, within one third of the total length of the beam, located in the middle between its two extreme parts.

The under-rail base can be a sleeper or turnout bar.

In the general case, the middle part of the under-rail base is understood as that part of it that is located at the interval from one edge of the base one third long to the other such edge. Nevertheless, it is optimal to place the radio tag (and, accordingly, the embedded part) in the middle of the sleeper or with a slight offset to the side within 10% of the total length of the sleeper. Within the specified gap, the embedded part can be displaced to any side of the sleeper and even adjoin such a side, be located on such a side.

If the under-rail base is a sleeper with under-rail platforms, then the embedded part with a label must be located between such platforms.

The under-rail base can be made of concrete (reinforced concrete) or polymer.

In the standard version, the upper part of the body of the embedded part must be flush with the upper surface of the base, however, the part can also be deepened (recessed) into the body of the base.

The proposed utility model is illustrated by the following drawings, which show a particular case of the utility model:

Fig. 1 - embedded part;

Fig. 2 - embedded part, longitudinal section;

Fig. 3 - reinforced concrete sleeper with an embedded part;

Fig. 4 - the location of the embedded part when pouring the sleeper.

A three-dimensional model of the device is also attached to the application.

Embedded part (Fig. 1) consists of a body 1 having the shape of a truncated cone. A recess 2 is made on the side of the base of the truncated cone. On the opposite side of the body 1, bushings 3 are made. A groove 4 is made along the perimeter of the recess 2, into which the cover 5 is inserted, forming an integral connection. Before connecting the body 1 and the cover 5, a radio tag 6 is installed in the recess 2.

The location of the embedded part on the under-rail base, for example, on a reinforced concrete sleeper 7, is shown in Fig. 3. The embedded part is located in the middle part 10 of the sleeper 7 (for example, between two under-rail bases 9) to ensure better reading by antennas mounted on train cars. The body 1 is located approximately at the same level with the surface of the sleeper 7. When pouring the sleeper 7, the embedded part is installed on the form 8 (Fig. 4). Bushings 3 are inserted into the holes on the form 8, after which the filling takes place.

Thus, the solutions used in the utility model provide optimal placement of an embedded part with a radio tag (RFID tag), which makes it possible to conveniently read the indications of a radio tag installed inside the embedded part, and thereby ensure the achievement of a technical result.
