Abstract

Device for laying railway track. When deploying a long rail in the course of tracklaying, it is desirable that the position of the rail relative to the sleeper be controlled and corrected as required. This is achieved if the roller (1) is free to move relative to the base (7), that is, in practice, relative to either the rail and/or the roadbed. This is achieved by mounting the roller (1) in a cradle (2) which is free to pivot in a base (7), the degree of movement of the roller/cradle relative to the base being limited by twin stops (4). The invention is provided with a carrying handle (6) to facilitate its practical use.

Description

Anordning vid anläggning av järnvägsspär enligt patentkrav 1, _ kännetecknad av, att foten (7) utförs av legerat stål, olegerat stål, aluminium, trä, armerad betong eller plast.Device for the construction of railway barriers according to Claim 1, characterized in that the foot (7) is made of alloy steel, non-alloy steel, aluminum, wood, reinforced concrete or plastic.

Metod vid anläggning eller demontering av järnvägsspår enligt patentlnav 1, kännetecknad av, att ett ospeciñcerat antal anordningar i förväg, eller i direkt anslutning till rälsens framdragning, placeras jämnt fördelade utefter den sträcka som ny eller begagnad räls skall dras fram över.Method for the construction or dismantling of railway tracks according to patent nav 1, characterized in that an unspecified number of devices in advance, or in direct connection with the hauling of the rails, are placed evenly distributed along the distance over which new or used rails are to be hauled.

Claims

1. l ll 16 21 26 507 959 Patent claims

A mobile self-correcting device which, together with an unspecified number of similar devices, is placed evenly in advance along the distance over which new or used rails are to be towed, and where a roller in each device, in addition to the ability to facilitate rail movement by unbraked rolling, also has its centerline freely movable in relation to both the longitudinal direction of the rail pulled over the roller on which the ground device stands, which enables different kinds of curvatures of both the rails and the work area for handling rails to be compensated, because if the rails tend to to lateral movements and thereby moves out towards any stirrup arm, the rails will for a short time abut and pull the stirrup arm with them in the direction of travel of the rail, whereby the center line of the roller in relation to the longitudinal direction of the rail changes and the rail returns to the roller and thus the device. until a new correction is required, something that is unpredictable, me which, due to the free movement of the roller in relation to both rails and underlying ground, always takes place automatically as long as rails are pulled over the device which is characterized in that the winding consists of a roller (1) mounted in a shaft pin (5). ) provided bracket (2), where the shaft pin is movably placed in a foot (7) provided with carrying handles (6) which is provided with double stop lugs (4) which limit the ability of the bracket and thus the roller to turn relative to the rails and the foot, and where the arms of the bracket are either fixed (8), in order to prevent rails from slipping off the roller, and to give the rails the opportunity to pull the bracket with them in the direction of travel of the rail and thereby change the center line of the roller in relation to the longitudinal direction of the rail. the stirrup arms are made with a semicircular cross-section and with the round part facing the roller, or foldable (3 and 3A) to facilitate removal of rails from the roller.
