ES2286403T5 - MAINTENANCE VEHICLE. - Google Patents

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.

Description

 The invention relates to a maintenance vehicle.

 From GB-A 1 535 502 a gantry crane, movable on the rails of a track, is known for the transport of track elements. The gantry crane has frame parts that run in the longitudinal direction of the vehicle in the area of the bogies, whose parts guarantee a corresponding frame resistance after a lowering of the lifting arrangement of track elements for a travel path.

 Through the EP-A 0 438 701 wagons are known for car transport. These are surrounded by a cover as protection against inclement weather, whose cover is movable in the longitudinal direction of the wagons in relation to a vehicle frame. 10

 The task of the present invention then consists in the creation of a maintenance vehicle that provides optimum protection against extreme weather conditions with a minimum of constructive effort.

 This task is solved according to the invention with a maintenance vehicle having the characteristics of claim 1. 15

 With such a solution, a very long working area can be created without problems with unlimited protection against inclement weather to work extensively without obstacles on a road under construction. By means of the two frame supports, on the one hand an unnecessary accumulation of mass can be avoided for a simple maneuvering capacity and on the other hand there is an effective safety barrier for the workers with respect to an adjacent contiguous track. Another advantage of the frame construction can also be seen in the fact that, if necessary, simple and efficient ventilation of the work space is possible by lifting the awning, without thereby impairing safety.

 Other advantages and conformations of the invention result from the dependent claims and the drawing.

 In the following, the invention is described in more detail with the aid of embodiments shown in the drawing. 25

 A maintenance vehicle 1 shown in Figures 1 to 4 can be moved on a track 3 through two bogies 2 arranged at the ends. As a vehicle frame, two frame supports 5 are provided parallel to each other and separated from each other in a longitudinal direction of axis 4, which are supported on the bogies 2.

 The two frame supports 5 are joined, forming a wagon box 6 without floor, to a multiplicity of 35 roof supports 7, which are respectively arranged in a plane that runs perpendicularly to a longitudinal direction of carriage 8. In conjunction with A canopy 9 is created by means of the two frame supports 5 and the roof supports 7 a working space 10 limited both in the longitudinal direction of the axle or in the transverse direction of the vehicle 4 and also in the vertical direction.

 As can be seen in Figure 2, the two frame supports 5 supported on the bogies 2 can be moved relative to each other in the longitudinal direction of axis 4 by means of drives 11. This allows the working space 10 to be increased from a normal width (see figure 3) in particular to work on track change segments - optionally to one or both sides - (see figure 4). For this, it is necessary that respectively two roof supports 7, arranged opposite each other in the longitudinal direction of axis 4, are fixed on a frame support 5 and form a free end 13 with a segment of 45 in a roof segment 12 approximately horizontal support 14 arranged below.

 As can be seen in Figure 3, the support segments 14 are arranged for the normal vehicle width overlapping in such a way that in the widened position (Figure 4) the free ends 13 become one above the other. The awning 9 consists of two awning halves 15, which respectively cover one half of the carriage box 6 from the free ends 13 to a lower support end 16. For ventilation purposes of the workspace 10 50 a lower end can be moved 17 of the awning 9 in the direction of an upper support end 18 of the frame support 5.

 As represented by a vision beam 19 (see Figure 1), a driver who is in a cabin 20 of a traction car 21 can see the road segment that is found unobstructed through the workspace 10 in front of the vehicle 1, so that a bilateral movement capacity is guaranteed. For the power supply of various work equipment 22, these can be connected by means of connections 24, if necessary, to hydraulic, compressed air and electrical conduits 23, which in turn can be connected to the traction vehicle 21.
