RU2377356C2 - Method of tie replacement - Google Patents

Abstract

FIELD: railway transport.

SUBSTANCE: invention relates to repair of railway track. Proposed method comprises removing ballast from unfit tie end face, anticreepers, shims and cushions. Tie replacement device is mounted on rail with the help of clampers. Slings are pulled from drums, laid under rails on both sides of said unfit tie and jointed together on tie end face. Said slings are wound on aforesaid drum to pull unfit tie out. Then, tie replacement device is mounted on to inner side of the rail and clamped under new tie position. Slings are pulled out from the drums, laid under rails and mounted on both sides of new rail. Now, ties are jointed at their end faces, slings are wound on the drum and new tie is laid in its place. Tie replacement device is removed. Finally, shims and cushions are fitted in place, spikes are driven in and tie block is backfilled.

EFFECT: lower labor input, higher efficiency.

Description

The invention relates to methods for repairing a railway track.

There is a method of replacing old railroad sleepers (RF patent No. 2072197, ЕВВ 29/00, 1994), which consists in pulling old sleepers from the side of the track and laying them on the platform of a working train transporting old and new sleepers moving along trains, and put new sleepers in the way, characterized in that new sleepers in the area of one end section of the train are placed on the side of the train or before it is put into the way, and new sleepers are put in the way using a device independently moved behind the specified train.

The disadvantage of this method is the need for a working train, which will require the closure of traffic for the period of repair of the track.

In the patent of the Russian Federation No. 2072016, ЕВВ 29/06, a method for replacing railway sleepers and equipment for replacing railway sleepers is proposed.

The inventive equipment for replacing railway sleepers comprises a lifting device for rails, a device for installing new sleepers, including racks for supporting ballast, a ballast planner, which is a plow connected to the traction unit, placed under the rails and located between the lifting device and a device for installing new sleepers. The method of replacing sleepers consists in raising the rails with a lifting device, removing old sleepers, leveling the surface of the ballast with a plow connected to the traction unit, installing new sleepers and attaching the rails to them.

The disadvantage of this method and device is the need for a set of equipment on the railway platform and the closure of train traffic.

The closest analogue is the method described in the “Technological maps for work on the current track maintenance”, approved on October 20, 2003, as well as in the “Rules and technologies for performing basic work with the current track maintenance”, approved on June 30, 1997.

According to the specified regulatory documents, the method of a single change of sleepers includes the following operations:

- a fragment of two sleepers and the removal of ballast by shovels;

- removal of anti-theft;

- removal of crutches and linings;

- installation of the traveling jack in the sleeper box and raising the rail;

- ejection of sleepers using crowbar and sleepers;

- leveling the bed under the sleepers;

- pushing the sleepers with ticks and crowbar;

- the installation of gaskets and linings;

- cleaning of the traveling jack;

- driving crutches;

- filling the sleepers.

The disadvantage of this method is the high complexity of extracting unusable sleepers from the canvas and installing a new sleepers. Work is carried out manually using high physical costs.

The purpose of this invention is to ensure the replacement of unusable sleepers with the least physical cost, without using heavy track equipment, as well as without interrupting the movement of trains.

This technical result is achieved in that the method includes the following operations:

- fix the device for replacing the sleepers behind the rail with the help of clamps;

- pull the slings from the drums of the device and bring them under the rails along the unusable sleepers, connecting them at the end of the sleepers;

- wind the slings on the drums of the device using, for example, a ratchet mechanism;

- pulling the sleeper from the sleeper box;

- rearrange the device for replacing sleepers on another rail and fix it with the help of clamps;

- pull the slings from the drums, put them under the rails and lay along the new sleepers, connect them at the end of the sleepers;

- wind the slings on the drums using, for example, a ratchet mechanism;

- set the sleeper in place;

- remove the device to replace the sleepers.

The drawing shows a device for replacing railway sleepers, a General view, which shows the installation for removing unusable sleepers according to this invention.

The device for replacing sleepers comprises a housing 1, two drums 2, mounted on a shaft at a distance from each other the width of the sleepers, slings 6, wound on drums 2, a ratchet mechanism 3 with a handle, a shaft mounted on one side, clamps 5, rails 7, sleepers 8.

The device operates as follows.

The device for replacing sleepers is installed on the rail 7 from the outside over the unusable sleepers 8, is fixed with the help of clamps 5 by turning them 90 degrees. Draw the slings 6, start them under the rails 7 and place them along the unfit sleepers 8, connect them together at the end of the sleepers 8.

Then wind the slings 6 onto the drums 2 using, for example, a ratchet mechanism 3 and gradually pull the unusable sleepers 8 from the sleeper box.

Then install the new sleepers in the reverse order.

The device for replacing the sleepers is rearranged on the rail 7 from the inside at the place where the new sleepers 8 should lie down, fixed using the clips 5 by turning the clips. The slings 6 are pulled from the drums 2, pulled under the rail 7 and placed along the new sleepers 8, at the end of the sleepers 8 are connected to each other. Using a ratchet mechanism 3 wind the slings 6 onto the drums 2, move the railroad tie 8 and put it in place. Upon completion of the installation of the new sleepers 8, the device for replacing sleepers is removed.

The proposed method for replacing unusable sleepers was tested in October 2004 at Irkutsk, the passenger distance of the VSZhD route.

The use of this method of replacing sleepers provided:

- reduction of the complexity and time of changing one wooden sleepers by 52%,

- to mechanize a heavy manual operation - pulling out a worthless sleepers and putting a new sleepers in place, especially when replacing a reinforced concrete sleepers;

- the ability to skip trains with a device fixed to the rail for replacing sleepers;

- the possibility of a single change of reinforced concrete sleepers and beams, which are 4-6 times heavier in weight by wood;

- low weight and simplicity of the device.

Claims (1)

The method for replacing sleepers includes removing ballast from the end face of unusable sleepers, anti-thefts, crutches, linings and gaskets, after installing a new sleepers, laying gaskets and linings, driving crutches and filling the sleeper box, characterized in that the device for replacing sleepers is fixed to the rail using clamps, pull the slings out of the drums, start them under the rails along on both sides of the unfit sleepers, connect them at the end of the sleepers, wind the slings on the drums, pull out the unfit sleepers, then rearrange the device to replace the Al on the inner side of the rail, fix it with clamps over the place where the new sleepers will be laid, pull the lines from the drums, put them under the rail and install them on both sides along the new sleepers, connect each other at the end of the sleepers, wind the slings on the drums, install a new sleeper in place, remove the device to replace the sleepers.
