Description

ANTI-RESISTANT DEVICE

The utility model relates to railway transport, and in particular to devices that prevent tipping of rail lanes when loading them onto rolling stock, in particular to platforms equipped with universal removable equipment for loading and transporting railway links.

The closest in technical essence and the achieved result is an anti-theft device according to the copyright certificate of the USSR Г ° 1608281, M.Yul: Е01В29 / 02, published in the JM bulletin for 1990.

The known device comprises a system of guide rollers with flanges, the axes of which are transverse to the longitudinal axis of the rail, with the lower supporting roller located under the rail sole and touching the rail sole with its upper part, and the upper roller located under the rail head and touching it with its lower part. The axis of the upper roller rests on racks rigidly attached to the base and located perpendicular to it.

The rail lash, passing between two rollers with flanges, with a fixed distance between them and touching them, keeps the perpendicularity of the lash cross section to the base unchanged, i.e. non-tipping (tipping) conditions in the transverse plane are provided.

The disadvantages of the known device are the relative complexity of manufacturing caused by the mandatory presence of racks and the location of the axis on them with the upper roller mounted on it.

In addition, the upper roll guard located above the head of the rail lash is an obstacle to loading

on rolling stock of the following transportation facilities located in height at the level of the upper roller. Otherwise, the known device does not allow to place except rail lashes, for example, packages of rail links of the railway track.

The purpose of creating a utility model is to simplify the device and expand the operational capabilities of the rail train equipped with the proposed non-turn-off device by providing the possibility of additional loading onto it of packages of rail links of the railway track.

This goal is achieved by the fact that in the anti-edge device containing holding rollers, rigidly connected to the base attached to the frame of the rolling stock, and oriented in space for interaction with the immersed rails and lashes, introduced single-rib holding rollers mounted with metal bars directly on the base, made in the form of a metal sheet rigidly fastened to the rolling stock frame, while the metal bars with holding single-rib ro ikami installed sishyaetrichno vertical plane passing through the middle of the supporting rollers whose centers are located on the longitudinal axis of the metal bars, and the distance between their central osyagli determined by the formula:

 where:

 -width of the neck of the submersible rail; - diameter of the flange of the holding roller; 2. A-drying1a minimum gaps between the flanges holding

rollers and the neck of the immersed rails.

distinctive features in the claimed technical solution. Consequently, the claimed anti-edging device meets the criterion of a novelty utility model.

The criterion of a utility model for industrial applicability is confirmed by the fact that the proposed device can be effectively and widely used for transportation of rail lashes when it is equipped with platforms for transporting packages of links of a railway track.

The anti-edging device for ensuring the lateral stability of rail lashes I from tipping over (tipping) when loading onto rolling stock 2 and located on roller bearings 3 (Fig. 3) consists of a base (metal sheet) 4 mounted on a rolling rail frame

composition 2 and rigidly attached to it (mount not shown); metal bars 5 (figure 4), each of which consists of three parts: 2 end, rigidly attached to the base 4, located along the axis of the immersed rail lashes T and located at an equal distance from the longitudinal axis of the immersed rails.

as well as the middle removable beam b, freely placed between the end parts of the beam and rigidly fixed between these parts with the help of pivots 7 inserted into the holes 8; retaining single-flange rollers 9 (flanges 10) (Fig. 2) located at the level of the sole of the rail whip when moving it along the roller supports 3 in a plane that passes through its longitudinal axis. Each holding single-flange roller is mounted on the vertical axis II (Fig. 2, 4), one end of which is secured with an increase in rotation by means of a nut 12 and a washer 13 directly in the base 4, and the other end is also rotatably in the center of the middle part of the beam b. Moreover, it interacts with the rail lash T of the flange 10 holding the first roller 9 has a profile of the upper surface of the bottom of the rail I. (Fig.2) Metal bars 5 with holding single-sided rollers 9 are mounted symmetrically to the vertical plane passing through the middle of the support rollers 3, the centers of which are located on the longitudinal axis of the metal bars 5. The distance between the central axes holding single-flange rollers (figure 2) is determined by the formula:

 .Where:

B is the width of the neck of the immersed rail T; X) the diameter of the flange 10 of the holding roller 9; D is the sum of the minimum clearances between the flanges 10 retaining

rollers 9 and the neck of the immersed rails I. The device operates as follows.

Rail lash I, immersed on rolling stock 2 and moved by external forces along the roller bearings 3,

there is a cross section where the holding rollers 9 with flanges 10 are located, after which a minimal gap is formed between the upper surface of the sole of the rail I and the working surface of the holding roller 9 (Fig. E).

With a minimum rotation of the cross section of the rail lash I under the action of tipping forces, the upper surface of the sole of the rail I (Fig. 3) interacts with the working surface (flange 10) of the holding roller 9, transferring the action of the tipping moment to the flange 10 of the holding roller 9 and then through the axis II of the holding roller 9, the parts of the timber 6 and 5, the base 4, on the frame of the rolling stock 2.

Thus, the overturning moment acting in the transverse plane under the action of external forces in the rail lash I when it is loaded is ultimately perceived by the rolling stock frame.

Since the reactive holding moment of the rolling stock is obviously (due to its size) greater than the overturning moment occurring in the rail lash, its lateral adaptability is ensured by the proposed device, which confirms the operability of the structure.

The transverse stability of the rail lash when loading is ensured by its interaction with the rollers located in the area of its sole, freeing the zone of the rail above its head for loading on the same rolling stock of the inverted track link, i.e. package links.

In addition, the placement of rollers holding down against rollover eliminates the need for struts (as in the prototype) to place the axle with the roller mounted on it, as interacting

with a rail head, ITO simplifies the design of the edge guard device and makes it cheaper.

The provided possibility of removing the middle part of the timber (by removing the pivots) allows loading rail lashes of not only the jointless, but also the link path without removing the butt plates. Director General JJ / S.B. ARKHANGELSKY
