Abstract

FIELD: maintenance and construction.

SUBSTANCE: invention relates to the field of maintenance and construction of the upper structure of the railway track, in particular to portal rail layers. The rail paver contains portals with supports and rail grips. Two portals are supported on supports by means of hinges. The hinges allow the legs to rotate 90° for transport. The height of the supports ensures work with rails laid on railway platforms. Each support has four pneumatic wheels. The wheels are hinged to the supports. The hinges ensure the passage of the railway curve. Four rail grips move along the portals on carriages by means of a worm gear. Raising and lowering the rails is carried out by hand winches. The winches are located on the outer sides of the portal supports.

EFFECT: number of workers involved in the layout of the rails is reduced.

Description

The invention relates to railway transport, and in particular to devices for changing railroad rails.

At present, in the construction and restoration of short-range railway tracks, the separate laying method is used, in which the elements of the track grid (rails, sleepers, fasteners) are transported to the laying site, and the track grid is assembled directly at the laying site. Transportation of rails to the place of their laying is carried out on railway platforms or track carts.

Rails are loaded and unloaded onto railway platforms using a crane, while loading onto track bogies is carried out manually. After unloading the rails at the work sites, it is required to lay them on the sleepers by a team of up to 36 people using rail tongs.

The disadvantage of this method of laying rails is the high complexity of this process.

Known hoisting device for loading/unloading railway rails, containing at least one crane-beam, equipped with a lifting hook mounted on it one rail capture [1].

The disadvantage of this device is that the rails can be unloaded only from this device to the second restored track or the side of the single track, which in turn requires the involvement of a large number of people.

A known crane for loading and unloading rails, containing a traveling trolley, fixed with a beam, a two-tube rack with a strut and a block at the end, a single-tube boom with a block at the end, a two-strand chain hoist for lifting the rail with a rail grip and a manual winch [2].

The disadvantage of this crane is that it can only unload rails from track trucks to the second restored track or the side of a single track, which in turn requires the involvement of a large number of people.

The closest analogue is a device for changing rail lashes, containing a trolley, a portal mounted on it, hydraulic power cylinders for lifting and transverse movement, as well as rail grips [3].

The disadvantage of this device is that it is preliminarily installed with the help of a railcar in the required place of repair, while the rails are laid in between the tracks. This does not allow rails to be unloaded by this device from platforms and track trucks.

The objective of the invention is to increase productivity when laying rails during the construction and restoration of a railway track through the use of carriages with rail grippers that provide rail laying using manual winches without the use of additional electrical and hydraulic means, while reducing the number of personnel involved, and also increasing the safety of execution the specified works.

The problem is solved by the fact that during the construction and restoration of the railway track it is required to unload the rails from the railway platforms or track bogies onto the laid wooden or reinforced concrete sleepers. In this case, the rails are laid to the required track gauge.

The technical result of this invention is to reduce the number of personnel involved and the time to perform work on the layout of the rails during the construction and restoration of the railway track by moving the rails from the platforms or track bogies to the laid railway sleepers.

This technical result is achieved by the fact that the portal tracker contains two portals supported on supports by means of hinges. The hinges make it possible to rotate the supports relative to the portals up to 90° and ensure its transportation. Rail clamps provide lifting and lowering of rails from platforms or traveling carts. Pneumatic wheels ensure the movement of the portal rail-laying machine along the axis of the railway track, and the distance between the portals allows the passage of railway platforms between them. At the same time, work can be carried out on single-track and double-track railway tracks without the use of additional lifting equipment, and the team for performing work can be from 4 to 8 people without the use of additional electrical and hydraulic means.

The essence of the invention is illustrated by drawings, where in Fig. 1 shows a portal rail-layer across the axis of the laid railway track; in fig. 2 shows a portal rail-laying machine along the axis of the laid railway track; in fig. 3 shows the hinged connection of the portal with the support; in fig. 4 is an isometric view.

The portal rail-laying machine includes portals 1 supported by means of hinges 2 having fixation on supports 3 of portals 1. Four pneumatic wheels 4 are installed on each support 3, ensuring the movement of the portal rail-laying machine along the subgrade or ballast layer. Pneumatic wheels 4 have an angle of rotation, which is provided by the swivel (not shown) with the support 3, to pass the curve of the railway track. The portals 1 are interconnected by a beam 5 up to 11.5 m long, and the portals 1 can move relative to the beam 5 in the direction towards each other, to ensure the operation of the portal rail layer with rails (not shown in the drawing) with a length of 12.5 and 25 m. On the portals 1 there are two carriages 6, which are equipped with rail grips 7. The movement of the carriages 6 along the portals 1 is carried out using a worm gear 8, while the distance between the two extreme positions of the carriages 6 ensures the capture of the rail (not shown in the drawing) from the edge of the railway platform. Raising and lowering the rail clamps 7 is carried out with the help of manual winches 9. To ensure the movement of the portal rail layer on the subgrade or ballast layer on the supports 3 there are handles 10, with which it is moved manually.

During the construction or restoration of railway tracks, rails laid on railway platforms or track bogies are delivered to the place of work. The sleepers are pre-laid on the subgrade or ballast layer according to the diagram. Portal tracklayer in assembled form and with the required length between the portals 1 is installed above the sleepers along the axis of the track being laid. After stopping the platforms or track trucks, the portal rail layer is manually moved so that the platform or track truck is between the supports 3, and the rail grips 7 are above the rails (not shown in the drawing), if necessary, the carriages 6 are shifted / extended to which the rail grips 7 are attached using a worm gear 8. Rail grips 7 are lowered onto the rail (not shown in the drawing) using a winch 9 and capture it. Then two rails (not shown in the drawing) are lifted using rail clamps 7 (2 rail clamps per rail). Lifting is carried out by manual winches 9 to the required height. The portal rail-layer is moved to the required distance along the track axis, while handles 10 are used for convenience. The rails are lowered (not shown in the drawing) using manual winches 9 until the rail rests on the laid sleepers (not shown in the drawing). The sleepers and rails are fastened and the operations are repeated.

In order to move the gantry rail-layer after construction or restoration of the railway track to a new place of work or to a place of storage, it is disassembled. The beam 5 is removed and placed separately, and the supports 3 are folded with the help of hinges 2 relative to the portals 1 up to 90°. In this form, the portal rail layer is loaded onto a platform or into a car trailer and transported.
