EP1369330B2 - 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.

By GB-A 1 535 502 is a track rail trackable gantry crane for the transport of track yokes known. The gantry crane has in the region of the rail chassis in the vehicle longitudinal direction extending frame parts, which ensure a corresponding frame strength after lowering the Jochhebeeinrichtung for a transfer travel.

By EP-A 0 438 701 Wagons are known for transporting cars. These are surrounded by a shell as weather protection, which is displaceable in the longitudinal direction of the wagons relative to a carriage frame.

The object of the present invention is now to provide a maintenance vehicle, which provides optimum weather and safety protection with a minimum of design effort.

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

With such a solution can be easily created a very long workspace with an unrestricted weather protection for a largely unhindered work on a track construction site. By the two trusses on the one hand an unnecessary mass accumulation for easy maneuverability is avoidable and on the other hand given to protect the workers an effective safety barrier to an adjacent adjacent track. Another advantage of the truss structure is also to be seen in the fact that in case of need a simple and effective ventilation of the working space by pulling the tarpaulin is possible without affecting the safety.

Further advantages and embodiments of the invention will become apparent from the dependent claims and the drawings.

In the following the invention will be 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 an enlarged plan view,
• 3 and 4 each a simplified cross section through the vehicle.

One in the Fig. 1 to 4 represented maintenance vehicle 1 is moved by two end arranged rail bogies 2 on a track 3. As a vehicle frame two parallel to each other and positioned in an axial longitudinal direction 4 spaced apart truss 5 are provided, which are supported on the rail chassis 2.

Both lattice girders 5 are connected to form a bottomless car body 6 with a plurality of roof beams 7, which are each arranged in a direction normal to a carriage longitudinal direction 8 extending plane. In conjunction with a tarpaulin 9, a working space 10 delimited both in the axial longitudinal direction or vehicle transverse direction 4 and in the vertical direction is created by the two truss girders 5 and the roof girders 7.

As in Fig. 2 can be seen, the two trusses mounted on the trolleys 2 truss 5 by drives 11 in the axial direction 4 are mutually displaceable. Thus, the working space 10 of a normal width (s. Fig. 3 ) in particular for processing turnout sections - optionally after one or both sides - to be increased (s. Fig. 4 ). For this purpose, it is necessary that two each in the axial longitudinal direction 4 mutually opposite roof rack 7 are each mounted on a truss girder 5 and in a roof section 12 a free end 13 with an adjoining, approximately horizontal support section 14.

As in Fig. 3 can be seen, the support portions 14 are arranged in the normal vehicle width overlapping such that in the widespread position ( Fig. 4 ) the free ends 13 come to lie one above the other. The tarpaulin 9 consists of two half-panels 15, each covering one half of the car body 6 from the free ends 13 to a lower beam end 16. For the purpose of ventilation of the working space 10, a lower end 17 of the tarpaulin 9 can be displaced in the direction of an upper support end 18 of the truss girder 5.

As by a ray of sight 19 (s. Fig. 1 ), a driver located in a cab 20 of a towing vehicle 21 can freely view through the working space 10 on the track section located in front of the vehicle 1, so that a mobility on both sides is ensured. For power supply of various working units 22, these are connected by connections 24 as needed with hydraulic, air pressure and electrical lines 23, which in turn can be connected to the towing vehicle 21.

Claims (2)

1. A maintenance vehicle (1), composed of two truss beams (5), extending parallel to one another and supported at their ends respectively on on-track undercarriages (2), which are each connected to a multitude of roof beams (7) for supporting a tarpaulin (9) and for forming a working space (10) delimited, in a longitudinal direction (4) defined by an axis of an on-track undercarriage (2), by the two truss beams (5) and, in vertical direction, by the roof beams (7), thus forming a floor-less vehicle body (6), characterized in that the two truss beams (5), for the purpose of enlarging the working space (10), are mounted for displacement with respect to one another in the axial longitudinal direction (4) by means of a drive (11).
2. A vehicle according to claim 1, characterized by hydraulic, pneumatic and electrical lines (23) with fittings (24) for supplying energy to working units (22).
