Abstract

Maintenance vehicle (1) comprises two parallel truss girders (5) supported at their ends on rail vehicles (2) to form a bottomless wagon (6). The wagon has a number of roof trusses (7) supporting a tarpaulin (9) to produce a working space (10) defined in an axial longitudinal direction by the two truss girders and in the vertical direction by the roof trusses. Preferred Features: The two truss girders are movably positioned relative to each other in the axial longitudinal direction by a drive (11) to increase the working space.

The invention relates to a maintenance vehicle.

The object of the present invention is to create a maintenance vehicle that provides optimal weather and safety protection with a minimum of design effort.

According to the invention, this task is achieved with a maintenance vehicle
which consists of the features according to claim 1.

With such a solution, a very long work area with unrestricted weather protection can be created without any problems for largely unhindered work on a track construction site. The two trusses prevent unnecessary mass accumulation for easy maneuverability and provide an effective safety barrier to an adjacent track to protect workers. Another advantage of the truss construction is that, if necessary, the work area can be easily and effectively ventilated by pulling up the tarpaulin without compromising safety.

Further advantages and developments of the invention emerge from the subclaims and the drawing.

In the following, the invention is described in more detail with reference to embodiments shown in the drawing.

Show it:

Fig. 1 a side view of a maintenance vehicle,

Fig. 2 is an enlarged plan view,

Fig. 3 and 4 each show a simplified cross-section through the vehicle.

A maintenance vehicle 1 shown in Fig. 1 to 4 can be moved on a track 3 by two rail bogies 2 arranged at the ends. Two lattice girders 5 positioned parallel to one another and spaced apart from one another in an axial longitudinal direction 4 are provided as the vehicle frame, which are supported on the rail bogies 2.

Both truss girders 5 are connected to a plurality of roof girders 7 to form a bottomless car body 6, each of which is arranged in a plane running perpendicular to a car longitudinal direction 8. In conjunction with a tarpaulin 9, the two truss girders 5 and the roof girders 7 create a working space 10 that is delimited both in the longitudinal axis or vehicle transverse direction 4 and in the vertical direction.

As can be seen in Fig. 2, the two lattice girders 5 mounted on the rail carriages 2 can be moved towards each other in the longitudinal direction 4 of the axis by drives 11. This allows the working space 10 to be enlarged from a normal width (see Fig. 3), in particular for processing switch sections - optionally to one or both sides (see Fig. 4). To do this, it is necessary that two roof girders 7, each opposite one another in the longitudinal direction 4 of the axis, are each fastened to a lattice girder 5 and form a free end 13 in a roof section 12 with an adjoining, approximately horizontal girder section 14.

As can be seen in Fig. 3, the support sections 14 are arranged in an overlapping manner in the normal vehicle width such that in the spread position (Fig. 4) the free ends 13 come to lie on top of each other. The tarpaulin 9 consists of two tarpaulin halves 15, each of which covers one half of the car body 6 from the free ends 13 to a lower support end 16. For the purpose of ventilation of the work space 10, a lower end 17 of the tarpaulin

9 in the direction of an upper beam end 18 of the truss girder 5.

As shown by a line of sight 19 (see Fig. 1), a driver in a cabin 20 of a towing vehicle 21 can see unhindered through the work area 10 to the track section in front of the vehicle 1, so that mobility in both directions is guaranteed. To supply energy to various work units 22, these can be connected as required by connections 24 to hydraulic, air pressure and electrical lines 23, which in turn can be connected to the towing vehicle 21.

Claims (6)

1. Maintenance vehicle ( 1 ) consisting of two lattice girders ( 5) running parallel to one another, each end of which is supported on rail bogies (2 ) , which are each connected to a plurality of roof girders ( 7 ) to support a tarpaulin ( 9 ) and to form a work space ( 10 ) delimited in an axial longitudinal direction ( 4 ) by the two lattice girders ( 5 ) or in the vertical direction by the roof girders ( 7 ) to form a floorless car body ( 6 ). 2. Vehicle according to claim 1, characterized in that the two trusses ( 5 ) are mounted so as to be displaceable relative to one another in the longitudinal direction of the axle ( 4 ) by a drive ( 11 ) in order to enlarge the working space ( 10 ). 3.
