Description

The invention relates to a railway vehicle for maintaining the track superstructure of rails with a device for pulling, holding or pressing in the context of rail repairs and repair work in which rails are interconnected. In this case, preferably a vehicle is used, which has an open to the track and protected working space.

Known is a vehicle for carrying out construction work in the railway track area, this being a housing for work in the track and a hollow box-shaped, rigid frame and two working platforms, which rest on two Schienenfahrwerke and enclose a free in the direction of the track area working space and the vehicle between the rail bogies in the transverse direction to the vehicle axle at least one recovery to the vehicle center ( DE 10 2009 033 516 A1 ).

Furthermore, such a vehicle from the DE 10 2010 014 596 A1 known, wherein the vehicle between the rail chassis in the transverse direction to the vehicle axle has at least one hinged side wall, each consisting of two longitudinally superposed side wall parts, wherein the upper side wall part attached to a joint or a series of joints on the vehicle frame and a second continuous joint / joint row with the lower side wall part is connected.

The DE 20 2011 004 799 U1 describes a maintenance vehicle having a vehicle frame extending in a vehicle longitudinal direction, each having at one end of a frame movable track rails track, wherein in an area between the two distanced rail bogies an open towards the track working space is provided and at each frame end a arranged for frictional connection of the vehicle frame with the rails clamping device is arranged, wherein at least one of the two clamping devices is formed by means of a drive in the vehicle longitudinal direction relative to the vehicle frame adjustable.

The clamping devices are firmly connected to the vehicle frame or the rail chassis. For transport, the lower part of the clamping device is slightly height adjustable

Furthermore, a device for producing an electrical connection of rails fastened to a rail-mounted carriage is known, the device (s) being arranged at one or both ends of the carriage ( DE 206 906 ). The devices are adjustable and slidable in carriage transverse direction and are composed of two hanging arms, which lie with their lower ends against the inner and outer sides of the rails. They are fixed to the chassis of the car and connected to this inseparable. In the transport position, the lower parts of the clamping arms can be raised slightly above the rail head.

Pure rail clamping devices are from the DE 219 944 , of the DE 31 20 149 A1 and the EP 1 057 933 B1 known. These are transportable and can be used independently of vehicles.

In all vehicles with a clamping / pulling device it is firmly connected to the vehicle and not adjustable in the vehicle transverse direction. The holding and pulling of the rails is thus not possible in all geometric positions of the track. In a rigid and immovable clamping / pulling device it must be accommodated in the area of the pivot in order to use this in all geometric positions of a track can.

The invention has for its object to construct a maintenance vehicle so that it is suitable for the use of a special clamping device for rail pulling, holding or pressing, which can also be used variably in track curves.

This is inventively achieved in that the vehicle has at its frame, preferably in the region of the rail undercarriages, at least two receiving devices that are suitable for fixed or detachable attachment or attachment of a clamping device, wherein the receiving devices are structurally designed so that the respective clamping device transverse relative to the vehicle longitudinal axis is adjustable.

The recording devices are usually arranged on the frame between and / or after the rail bogies.

The receiving devices have a hook and / or a pin and / or an eyelet and / or a cylinder and / or a guide to which the rail clamp can be attached.

The execution of the recording devices allows the adjustment or the displacement of the rail clamps transverse to the vehicle longitudinal axis. The displacement can be done freely, purely mechanically and / or by means of a drive, lifting cylinder or the like.

The recording devices have fuses against slipping or unintentional displacement of the rail clamps, wherein the fuses can be made stepless or stepwise adjustable.

The receiving devices are designed such that the rail clamps attached thereto can be longitudinally displaced or displaced relative to the vehicle longitudinal axis, the longitudinal displacement or displacement being effected by means of a drive (eg a hydraulic cylinder) or a threaded rod or a clamp arranged on or in a guide is executed.

The receiving device can advantageously be executed horizontally and / or vertically one or zweigelenkig and / or hinged and / or rotatable.

The receiving devices may comprise a lifting cylinder.

The recording devices can be designed to be removable.

Advantages of the invention

• - The vehicle can be used with the recording devices according to the invention and the rail clamps for pulling, holding or pressing rails.
• - The rails can be kept exactly in their position.
• - When splitting the rails in the track clamped at 26 ° C, they can no longer retract after being clamped in the clamp at cold temperatures.
• - The rails can be pulled to their original position or beyond.
• - By a lateral and relative to the vehicle axle adjustable embodiment of the recording devices and / or the rail terminals pulling, pressing or holding the rail at each track geometry (eg., In sheets and elevations) can be performed.
• - The recording devices and / or the rail clamps are removable, hinged and / or articulated, resulting in a wide and variable use under almost any condition.
• - The recording devices or the rail terminals and their drive can be moved completely independent of the vehicle.
• - If the receptacles are not needed for certain operations, they can be removed with little effort.
• - Replacing a defective recording device is quick and easy.
• - The recording devices can each be between the rail bogies (bogies), ie lying inside and / or after the rail chassis, so lying outside, resulting in a diverse operational capability of the vehicle both when pulling, as well as holding, as well as when clamping the rails leads.
• - Due to the arrangement of the recording devices in front of and / or behind the rail chassis of the vehicle, pressing, pulling and holding work on rails in maintenance and -setzungsarbeiten in different lengths are variable feasible.
• - The terminals used can be easily removed or replaced if necessary, which facilitates use in various superstructure or rail shapes or in special cases.
• - To attach the devices, no major structural adjustments to the vehicle are necessary.

3 - The vehicle frame with internal recording devices

4 - A tilting receptacle with removable clamping device

5 - The transversely displaceable on a pin recording device with rotatable clamping device

6 - The recording device on a socket pin with a clamping device in the side view.

7 - The recording device on a socket pin with a clamping device in plan view

8th - The vehicle with simultaneously movable and pivotable receiving device and clamping device in the curved track section.

The vehicle has a frame 1 on preferably two rail bogies ( bogies) 11 is supported on the rails 12 are guided.

The two rail bogies (bogies) 11 are each arranged at the vehicle ends.
