FR2606723A1 - Adaptation to the railway site of a roadworks slip form machine, including reference guidance by the rail - Google Patents

Abstract

Modification of an existing roadworks slip form machine to allow it to be used on a railway site. The invention consists in: - adding 2 plate-layer's trolleys and a hydraulic control system allowing running on a railway track; - using the rail as a reference basis, both from the layout and levelling point of view, which makes it possible to be sure that the gauge dimensions imposed are respected.

Description

 The invention relates to a POWER CURBERS CK 6700 machine manufactured in the United States and designed for the execution of curbs, ditches and gutters using slippery formwork on road sites and modified to be able to travel on railways - whatever 'spacing and in order to be able to execute station platform or other edges, gutters, ditches with the rail as a reference base both in terms of layout and leveling, the sliding formwork system being preserved.

Scope
All constant concrete profiles between 0.20 and 3.00 m wide, - curbs, gutters, paving, safety barriers, cycle paths,
concrete ditches.

Operating principle: continuous use of ready-to-use concrete by a self-propelled machine adjusted in altitude as in direction on a theoretical materialized line.

- the concrete received in a hopper is liquefied by vilJrantes needles then formed in a mold with the desired profile. The mold is integral with the chassis of the machine, a principle guaranteeing the obtaining of an optimum density and resistance of the concrete. The interchangeable mold can be mounted indifferently, laterally or between the tracks.

- the machine follows the requested theoretical direction, it absorbs the variations of the ground by repositioning itself via its hydraulic cylinders - all the profiles can be implemented by this method as long as they are respected
- a relationship between the height and the volume of the profile, --- a fruit opposing the natural collapse of the concrete.

 This machine designed for the execution of road works cannot be used on the railway site because of a) the absence of a bogie allowing rolling on a railway track, b) a guidance system relating to the rail which due to the importance of gauge issues in the rail industry constitutes the benchmark par excellence.

 To allow the use of the machine in ferro vinaire environment, we therefore proceeded to the following modifications: ~ addition of 2 lorrys, to allow circulation on the railway, whatever the spacing. These lorrys are hydraulically controlled and can be raised to allow circulation on the construction tracks.

These lorrys have been modified as follows (Li) - addition of a gusset at the right of each rolling element pierced in the middle and provided with a pin supporting the angle iron and allowing its articulation, (2) - an iron articulated 80 m / mx 80 m / m square ensuring the chassis connection (lorry both in rolling position on the rail and in lifting position for "road" traffic), - a jack) hydraulically controlled allowing either lifting or lowering the lorry.

- modification of the electronic probes to allow guidance in layout and altitude only from the rail which serves as a reference.

As the platforms, borders and gutters are always located in relation to the rail, the dimensions of the template to be observed are therefore necessarily observed.

The machine thus modified according to the present invention has the following advantages
- production of one linear meter of border per minute, i.e. a m8-r - on average per day, while the traditional installation of prefabricated borders is of the order of 30 linear meters per day, i.e. a yield multiplied by 10.

- abolition of work trains and handling equipment necessary for the supply and installation of prefabricated curbs
- removal of breakage.

Concrete feeder
Because the machine runs on the railway during its operating time, we have imagined a rotary mixer (Truck MIXER) ensuring the supply relay between the channels arriving from the concrete plant. It is a classic mixer but equipped with a 180 degree rotation system.

Application domain
This adaptation is likely to interest all companies working for rail networks - private and national - which are required to carry out passenger platform edges in stations, gutters, ditches with the route and the reference as a reference. altitude of the nearest rail.
