EP1889770A1 - Train for construction and maintenance of rails on tracks, comprising at least one vehicle - Google Patents

Abstract

The construction and maintenance train has a vehicle (11). A complete system is modular arranged. An individual vehicle is self-motorizing with assigned emergency generator and batteries. A platform (5) is free from fixed installed super structural parts. A driving motor assigned to the vehicle is designed as under floor system. The super structural parts are replaceable and exchangeable. The functional units are positioned in the under floor area, and under the platform.

Description

The invention relates to a construction and maintenance train for rail use, which consists of at least one vehicle.

Rail cars of various kinds have already been described several times.

So z. B. a rail car has been described in which the individual working and functional elements of the drive system, such. As the main drive with diesel engine, torque converter, transmission gear, etc., are mounted separately on the carriage housing and coupled with arranged in bogies driven devices. The couplings are here carried out easily detachable to replace the bogies to adapt to different speed requirements. In such rail vehicles, the arrangement of the drive units on the carriage housing requires expensive installation measures, which are carried out in the course of the overall production of the rail vehicle.

Functionally comparable solutions in the field of ground transport systems are also known. It is known z. For example, such a transport system, which consists of an underfloor rail system with a primary conductor for non-contact inductive energy transfer to an electrotransport vehicle and equipped with a guide channel for the mechanical guidance of the electrotransport vehicle. This transport vehicle has this - in order to meet the given task solution - in a rotary bearing in a horizontal direction steering unit with a projecting into the guide channel guide pin, a horizontally relative to the electrotransport vehicle pivotable pick-up unit with a secondary conductor for the inductive energy ,

Notes on the solution according to the invention, however, can not be found in this publication.

Also described was a self-propelled railroad car, the z. B. has a novel power transmission for speeding maneuvering, z. B. a torque transfer to at least one driven axis of the car, not in the axle shaft between the two wheels, but from the outer end face area, d. h., From the axle stub protruding over a respective axle wheel on the axle shaft. So z. Example, a transmission gear provided, which is arranged achsstummelseitig, about which the power transmission can be done on the front side on the projecting over a wheel axle stub axle. Again, no solution according to the invention can be found.

In another known solution principle has been described to put together a train with a large number of over an end face passable vehicle trolley. Here, the individual vehicles drive over the front of a last vehicle transport car of the assembled train in the train. The vehicles drive over the entire length of the train up to the locomotive at the Zugspitze. After reaching the destination of the train, all vehicles or transport loads must travel by train on the side of a specially prepared vehicle transport vehicle or drive backwards driving over the front of the last car after performing the maneuvering.

Again, no solution to the invention disturbing solutions can be found.

The invention is therefore an object of the invention to provide a construction and maintenance train for rail use, which allows an economical driving in the field of construction sites and on their access routes, these systems should be used for rail transport, the transport of equipment, crew and / or workshop container and in addition in case of failure (eg in the tunnel) the fastest possible work readiness is ensured. The system should always be kept operational with simple means, without significant maintenance stops in the repair and conversion area.

This object is achieved in that the overall system is modular, the individual vehicles have their own engine, each of which emergency generator, batteries, batteries, etc. are assigned. In addition, the platform is designed to be free of permanently installed superstructures and the drive motor associated with the individual vehicle with all ancillary and auxiliary equipment as underfloor system.

Essential for the solution according to the invention is the fact that the bodies are interchangeable or replaceable, so that - due to the modular vehicle body and the inventively provided take-back - depending on the application form and area a fast and easy adaptable to the respective purpose of operation equipment with implements, Transport elements, containers, etc. ensures.
A significant advantage of the solution according to the invention is that without significant or system-changing adaptation work, load bearing, transport of loads and implementation of maintenance are possible.

In a further variant of the invention some or all vehicles are equipped with a hydrostatic drive.

An essential advantage of the invention also lies in the fact that the required traction power is provided by the individual vehicles without additional railcar. Another variant of the invention describes that the underfloor engine systems are fastened by means of quick release positive-locking fasteners on the frame of the vehicle, with motor bogies are used and the drive axles can be driven individually.

Another advantage shows the variant in which the base frame is designed as a welded construction, has two side members and the two main cross member for bogie recording and other cross member are connected together.

It has proved to be functionally advantageous that the system has container receiving points in the area of the platform in the 5-foot grid.

An advantage of the solution according to the invention is that the final drive is tuned to the speed range up to 60 km / h, wherein in towing the axle is lubricated by a splash lubrication and runs along empty, with towing speeds of 100 km / h are possible. In one variant of the invention, a diesel engine with 210 kw output power at 2,300 rpm is used. The variability of the system according to the invention has the advantage that at least 45 container variants can be used in a modular manner.

These functional elements such as containers etc. can be set up and set down with an external and / or system-inherent lifting device.

For special applications, the system can be equipped with a cable drum reel unit. Alternatively or in parallel, the use of aerial work platforms is provided.

To improve the stability, the system has support units.

The equipment of the vehicles depending on the application with workshop or crew containers and cranes of different sizes is advantageously provided in various variants of the invention.

Another advantage is the variant according to the invention, in which the brake system is equipped with two active in the longitudinal direction floating on the bogie frame combination brake cylinders with active and spring storage part, the wheelsets are braked by the main cross member against the wheelset on one side by means of composite brake pads. The wheelsets are equipped with 2 internally ventilated shaft brake discs, on each side of which an elastic suspension unit suspended from the bogie frame acts.
