Abstract

A process and device are disclosed for exchanging wheelsets of railway vehicles by means of a travelling unit, the railway vehicle being brought onto a supported track section. The invention addresses the problem of developing a structurally simple and economical wheelset-exchanging device which can be moved without its own drive and be used with all standardised track bridges and wheelsets in a polyvalent manner. The device should also be low-maintenance, operationally reliable and very stable. According to the invention, this problem is solved in that the supported track section (3) between two tracks comprises a working pit (2) in which a mobile wheelset exchanger (1) fits precisely in the area of an extendable standardised track bridge (4) by means of a mobile hoisting vehicle, preferably a fork lift truck. The mobile wheelset exchanger comprises one or more, preferably hydraulic, telescopic cylinders, the supported tracks comprise detachable standardised track bridges, and the standardised track bridges comprise a locking/unlocking structure (S) and an earthing device.

Description

The The invention relates to a method and a device for changing wheelsets on rail vehicles by means of a movable device, wherein the Rail vehicle brought to a raised track section becomes.

It is known, wheelsets or bogies of rail vehicles by means of a gripping under the flanges Lift lifting table.

From the DE 42 04 347 C1 is a lifting and lowering device for the assembly change on rail vehicles on elevated tracks known, the track bridge can be lowered to the level of the working plane. By means of a floor-mounted receiving device, the wheelset can then be moved out laterally.

Also known is a combined lift-lowering device for the assembly change on rail vehicles ( DE 198 38 483 C1 ), in which a lift table can be lowered flush down to the hall floor. The two track bridges are firmly connected to each other via a base frame.

In addition, a device is known which makes it possible to raise or lower a rail vehicle via mobile lifting blocks as a whole ( DE 101 56 010 A1 ). The jacks have independently adjustable in height brackets with hoist bearing surfaces or claws on. The brackets are designed to be displaceable transversely to the vehicle.

Also, air cushion operated wheelset change devices are well known ( DE 38 22 832 A1 ).

In addition, a Radsatzwechsler is known which has its own main and auxiliary wheels for independent retraction under a normal track bridge and is moved sideways over a working bridge located under the track bridge ( DE 41 27 028 C1 ). The wheel set changer is supported by two cross members on the boundary of the working pit. The non-elevated track bridges are recorded by two recordings of Radsatzwechslers after unlocking and stored laterally on Nebenhubwerke. The locking and unlocking of the track bridge will not be described in detail. Also, the device has no special grounding device. The wheel set changer is positioned exclusively via the main and auxiliary wheels and lifted via hoists.

all known lifting devices have in common that they are designed consuming and awkward to handle and are expensive to buy. In addition, elaborate and expensive devices for track bridge removal needed which in turn are very prone to failure. Furthermore, in the case of air cushion drive, a more expensive and expensive hall floor is required. An exact adjustment of the wheel set to be removed and installed is easily possible with any device. The well-known wheelset changer just under the vehicle to position, is very expensive and time-consuming.

Of the Invention is based on the object, a method and an apparatus for wheel replacement on rail vehicles by means of a movable Device, wherein the rail vehicle on an elevated Track section is brought, or arranged to indicate. It is a structurally simple and cheap Radsatzwechselvorrichtung to develop, without own drive, with a mobile lifting vehicle (Forklift) movable and at all single-track railway bridges and wheelsets can be used multivalent. The device should also be low maintenance, safe and very stable.
