Abstract

FIELD: construction.

SUBSTANCE: invention relates to railway track construction and repair, particularly, to continuous welded track laying. According to the rail strings movement method during their welding and laying in the track, the parallel rail strings are drawn from the train, they are fixed in guiding trays with anti-edging devices on the module with further processing during butt welding. In the process of drawing pairs of rail strings, they are displaced in the transverse direction by means of movable guide trays with anti-edging devices and fixed, thereafter, the first module is used to weld rail strings of one rail line located in the middle of the working zone of this welding module. Then rail strings are transferred to second welding module with transverse displacement in opposite direction, where, after their fixation, the rail strings of the other rail thread located in the middle of the welding zone of the second welding module are welded. Further, welded rail strings of both rail lines are transferred to an anti-edging platform with a guide apparatus of the rail carrier for further laying on the track.

EFFECT: as a result, it becomes possible to simultaneously weld parallel rail lines on two welding modules with a cover.

Description

The invention relates to the field of construction and repair of railway tracks, in particular, to the technology of laying continuous welded rail tracks.

From the description of the utility model to the patent RU No. 33583 under class E01B 29/16, published on 27.10.2003, a working train for welding and laying rail strings is known. In this known device, rail strings are successively pulled out from a rail-car train, fixed in the guide trays of a covered wagon, and butt welded with subsequent technological processing on this wagon.

However, all technological operations are carried out only on one rail thread. To lay the second rail thread on the track, the working train needs to be maneuvered again in the rail laying area, which significantly increases the time of work. This makes repair work especially difficult, given the tight deadlines for train traffic restrictions on the track section.

From the description of the utility model to the patent RU No. 219291 under class B61D 17/00, published on 11.07.2023, a platform with a shelter for welding rail strings is known. When using this known device, rails are turned over during their welding and laying on the track, during which a pair of parallel rail strings are pulled out from the rail-carrying train at once, they are fixed in the guide trays with anti-edging devices of the module, followed by technological processing during butt welding on this module. This technical solution is adopted as a prototype.

The prototype envisaged the implementation of all technological operations on welding two parallel rail threads at once on one welding module with a shelter. However, further design studies showed great difficulties in implementing all technological operations on one welding module due to the limited transverse space of the welding module in the overall dimensions of the rolling stock. The use of existing technological equipment: a welding machine, equipment for cutting the end sections of rails, means for removing burrs and grinding welded joints turned out to be difficult.

The technical task of the invention is to ensure unimpeded operation of the above-mentioned technological equipment during the simultaneous processing of two parallel rail threads.

In order to achieve this technical result, when moving rails during their welding and laying on the track, in which pairs of parallel rail strings are pulled out of a rail-carrying train, they are fixed in guide trays with anti-edging devices on a module with subsequent technological processing during butt welding, unlike the prototype, in the process of pulling out pairs of rail strings, they are shifted in the transverse direction using movable guide trays with anti-edging devices and fixed, after which, on the first module, the rail strings of one rail thread are welded, located in the middle of the working area of this welding module, and then the rail strings are transferred to the second welding module with a transverse shift in the opposite direction, where, after they are fixed, the rail strings of another rail thread are welded, located in the middle of the welding area of the second welding module, and then the welded rail strings of both rail strings are transferred to the anti-edging platform with the guide apparatus of the rail car for subsequent laying on the way.

The use of two modules with technological equipment not only facilitates the work of service personnel, but also ensures the continuity of laying parallel track threads.

This technical solution is explained by drawings, where: Fig. 1 shows a diagram of the movement of rail strings using two welding modules; Fig. 2 shows a possible position of the welding machine operator using the proposed method; Fig. 3 demonstrates the difficult position of the operator in the rolling stock clearance when using a prototype object.

The proposed method is implemented as follows. After the technological train arrives at the continuous welded track laying area, pairs of parallel rail strings 2 and 3 are pulled out from the end platform 1 of the rail-carrying train. In the process of pulling out the pairs of rail strings, they are shifted in the transverse direction using movable guide trays with anti-edging devices and fixed, after which, on the first module 4 with a shelter, butt welding of rail strings 3 of one rail thread, located in the middle of the working area of this welding module 4, is performed with subsequent technological processing. Then, rail strings 2 and 3 are transferred to the second welding module 5 with a transverse shift in the opposite direction, where, after they are fixed, welding of rail strings 2 of another rail thread is performed in the middle of the welding area of the second welding module 5. Rail strings 2 and 3 connected by welding are transferred to the anti-edging platform 6 with a guide device of the rail-carrying vehicle for subsequent laying on the track.

The offset of the rail strings allows the operator of the welding machine 7 (see Fig. 2) to be freely positioned on different sides of the processed string inside the covered module 4 or 5. As shown in Fig. 3, the operator will not be able to position himself within the overall dimensions of the welding module when performing welding work using the prototype object.

The use of this method is possible when using the two-section rail welding complex RSM-2000, which will facilitate the work of the maintenance personnel and ensure the continuity of laying parallel track threads without additional maneuvering of the rail-carrying train.

Devices and fittings implementing this method can be manufactured at a machine-building plant using existing construction materials, components and technologies.
