RU2340719C2 - Track laying system - Google Patents

Abstract

FIELD: construction industry; railways.

SUBSTANCE: track laying system consists of railway platform, drive including pump control unit connected with hydraulic stations by means of pipeline, control unit, and mounting beam. On its curb ring track laying system has a column with a hinge and travelling mechanism, and is connected with beam. Beam is connected through additional turntable with hydraulic telescopic crane arm, on the end surface whereof mounting turntable is located which is connected with crane arm by means of hinge and travelling mechanism.

EFFECT: providing the possibility to install and remove track structure due to ability to carry out works from one and the same station in parallel sections at the distance equal to sum of arm telescoping lengths and beam length.

Description

The invention relates to the field of engineering and is intended for laying and dismantling the upper structure of the railway track.

As the closest analogue, a crane for traveling work is proposed, presented in SU 307671 A1, 01/01/1971, IPC ЕВВ 29/26.

The crane for traveling work is designed to perform repair and restoration operations and among the shortcomings has a limited radius of work and low load capacity.

The purpose of the invention is to eliminate the noted disadvantages and to provide the possibility of mounting and dismantling the upper structure of the railway. the way.

This goal is achieved by using a combination of well-studied truck crane equipment in combination with turntables.

The tracklayer comprises a railway platform 2, a drive 1, comprising a pump and control unit connected by a pipeline to hydraulic units, a control unit, a mounting beam 13, characterized in that it comprises a rack 5 with a hinge and a movement mechanism 7 connected to the beam on the slewing ring 3 6, which through an auxiliary turntable 8 is connected to the boom of a hydraulic telescopic crane 9, at the end of which there is a mounting turntable 11 connected to the boom by a hinge 10 and a movement mechanism 12.

The invention is illustrated by drawings. In Fig. 1 is a side view of the installation, in Fig. 2 is a side view with a grip of the sleeper grill 14 with an arrow of a crane 9 with a turn of the boom with a support rotary circle 3 and an auxiliary turntable 8 by 180 °, in Fig. 3 is a side view with a turn of the installation supporting rotary circle 3 by 180 °, figure 4 is a side view with the movement mechanisms 7 and 12 lowered by the boom of the crane 9 with a load.

The essence of the work of the track stacker does not differ from the actions of a hydraulic truck crane. Horizontal movements are carried out by supporting 3, auxiliary 8 and mounting 11 turntables.

The technology of laying and dismantling the sleeper grids from the existing one is different in that the proposed track stacker is able to work from one parking lot, in parallel sections, remote at a distance equal to the telescoping length of the crane jib + beam length 6, which will find application in the construction and reconstruction of multi-way interchanges of railway stations . In addition, the mounting turntable is compatible with a wide range of mounted construction equipment used in the construction of the railway right of way.
