Description

The invention relates to a vehicle for carrying out construction work in the railway track area, this being a housing for work in the track.

Work on the track requires heavy-duty tools, which at present often can not be ergonomically arranged, as well as increased safety efforts to protect workers from accidents caused by approaching trains. As a rule, safety posts are used for this purpose, which issue warning signals in good time by means of a bugle. The necessary expenses are considerable in the large number of construction and maintenance measures often to be performed. In addition, the employees are exposed to the weather foot defenseless, which can also adversely affect the quality of the performance performed.

For this reason was in the GB 1 535 502 as early as 1978 a machine for use in track construction protected, which has a hinged frame construction, inside which the employees can work protected.

In the FR 2 786 148 is designed as a framework trained frame construction of such a vehicle in more detail.

A maintenance vehicle with two truss girders running parallel to each other and each supported on rail trolleys, which are used to form a bottomless trolley and to support a roof tarp, describes the EP 1 369 330 B1 , The two trusses are mounted to increase the working space by a drive in the axial direction to each other displaced. Querverschiebbarkeit two longitudinally arranged truss girders of a maintenance vehicle requires a very high design overhead, since the truss girders must be movably mounted as supporting parts on the bogie and a number of drives at different points of the vehicle are necessary.

The transport of material (eg rails) and a higher conversion speed are also not possible for the reasons mentioned. Broadening in the area of platforms is possible only to a limited extent.

The EP 1 789 299 B1 refers to another maintenance vehicle with two longitudinal vehicle stops which are transversely displaceable / translatable by a drive to increase the working space at the construction site. The vehicle roof, the vehicle limitations and the shots for the implements are attached to and supported by a transversely centered vehicle frame. The vehicle frame has a portion which is bent upwards. The arrangement of a centrally positioned in the transverse direction of the vehicle and upwardly cranked vehicle frame is structurally a disadvantageous embodiment, since this requires a massive construction of the carrier and the weight of the vehicle can increase significantly. The advantageous central access of the employees from the platform to the work space is blocked by the centrally arranged frame. Neither tool nor material can be introduced laterally into the vehicle. - ie the vehicle can not be loaded from the side.

From the EP 1 880 913 A2 is another track maintenance vehicle is known, which also has an upwardly cranked frame construction, the side walls, however, are not transversely displaceable, but can be folded over a joint. The vehicle has two platforms above the chassis. The folding of the side walls via a joint, which is arranged in the upper region of the vehicle sides below the vehicle roof / vehicle frame. The side walls are thus unfolded as a whole. They are angled. Work equipment fastened to the hinged side wall, such as track processing means, changes its position by unfolding and can not always remain vertically arranged. This makes it very difficult for the operators to remove the heavy work equipment and the working material and bring it into working position.

The bent-up vehicle frame is designed here as a lightweight support structure. The girders are mounted only in the upper part of the vehicle so that this wagon can not be used for higher speeds and does not meet the criteria for setting in train.

The DE 20 2006 011 589 U1 describes the machine mounts of a maintenance vehicle closer, wherein the machine mount is fixed to the frame carrier and has a drive, so that it is displaceable in the vehicle longitudinal direction and transversely displaceable over a cross member. On the machine mount a track construction machine is releasably attached.

All maintenance vehicles have in common that they also have to be used in track curves. The existing route network has very many and sometimes very tight curves. Every moving track vehicle must be at each point of the Rail network - so even in curves - a set Lichtraummaß comply. As a result, the narrowest curve radii greatly affect the maximum allowable width depending on the length of a vehicle. For the reasons mentioned above, all existing maintenance vehicles have the disadvantage that their length is too short and thus their enclosed space is too small to be able to effectively use them on all sections of the track or they must widen at the workstation in order to ensure a sufficient working space , The frame stability is also limited in the long vehicles.

The invention has for its object to develop a track construction vehicle, which adheres to the required Lichtraummaß driving at all points of the route network, yet a greater length and simple construction as possible with maximum stability of the frame, the operating forces provided a sufficiently large workspace and an optimal position of the track processing means to be used is adhered to the track.

This is inventively achieved in that
the vehicle has a hollow box-shaped, rigid frame and two working platforms which rest on two rail bogies and enclose a working space that is free in the direction of the track area, wherein the vehicle has at least one hinged side wall between the rail bogies in the transverse direction to the vehicle axle, each of which is arranged longitudinally above one another Sidewall parts, wherein the upper side wall part is fixed to the vehicle frame with a continuous joint or a joint row and connected via a second continuous hinge / joint row with the lower side wall part.

In an alternative embodiment, the vehicle may have a recovery on both sides of the vehicle longitudinal axis, which is designed in the transverse direction in an angled (or oblique) shape. It may have a different shape at the top of the frame than at the bottom. Thus, even in curves with an overlong vehicle, the required clearance is maintained without complex technology and with very good frame stability.

The side walls and / or the upper fixed frame alternatively each have at least one receiving device for rails. These are to be used in the transport case as shelves for a supply of rails that do not need to be transported separately.

The hinged side panels are placed vertically in the transport position or pulled slightly (5-20 °) in the direction of the center of the vehicle so that they can not get caught in any obstacle while driving. In the working position, the upper side wall part is folded by up to 80 ° to the outside, wherein the lower side wall part occupies a largely vertical position. In order to facilitate the lateral loading even further, the Ausklappwinkel can be increased beyond.

Advantages of the invention:

• • the vehicle can be manufactured in the folded state of the split side walls in curves in a length that had led to problems for previous vehicles,
• • the frame can be constructed very stably thanks to its hollow box-shaped
• • the adjustability in train bandage can thus be achieved
• • higher speeds can be driven
• • payload with several tons of material (such as rails) is possible
• • a complicated technique for transversely shifting the side walls is not necessary
• • the split folding mechanism ensures that there is always a sufficiently large working space only in the actual working area,
• • the split section pulls the lower area of the side walls upwards so that even in the area of low obstacles (eg platforms, LS signals etc.) it can be secured in the track area right up to the obstacle,
• • the lateral introduction of tools and material is possible with the raised side wall raised,
• • the hinged wall has no vehicle static function and can therefore be designed slim, which has a positive effect on the size of the working space,
• • this improves the effectiveness of the vehicles,
• • The vehicle can be moved in both directions controlled
• It has, if necessary, its own drive, but it can also be moved behind a tractor,
• • Employees can enter and leave the working area via lockable entrances / exits / doors at the front ends without entering the danger area of the neighboring tracks,
• • working machines can be used detachably via the longitudinally and transversely displaceable lifting devices, which ensures that every point of the working space can be reached and processed,
• • Trays can be stockpiled and transported without additional equipment through the shelves located in the side walls and / or upper fixed frame.
• • the lower part of the side wall and the attached tools and rails are always in a vertical position, which facilitates their handling,
• • due to the vertical position, the working space remains relatively large even when the side wall is not unfolded,
• • The tools required can be arranged ergonomically and optimally aligned to the track, which protects the health of the employees,
• • the working space can be illuminated optimally,
• • the weather protection for the employees is given, which also improves the quality,
• • The tools used are weather-protected and can be stored professionally, which extends their service life and reduces the need for repair,
• • there is better environmental protection through lower emissions.

embodiment

Reference to an embodiment, the invention will be explained in more detail below.

Showing:

1 - The vehicle in the side view

2 - The vehicle in plan view with angled recesses and unilaterally unfolded side wall

3 - The vehicle in plan view without angled recesses and with one side unfolded side wall

4 - The vehicle in cross-section, left wall folded out laterally, right in vertical transport position

5 - The vehicle in cross-section with retracted side walls in transport position, in variant 1 (left side) remains the lower part of the side wall in a vertical position, in variant 2 (right side wall) remains the side wall straight, the lower part is tilted.

The vehicle has the hollow box-shaped, rigid frame 1 , the working platforms 2 ; 3 , the side walls 4 , the recoveries 6 and the rail bogies 7 ; 8th on ( 1 . 2 . 3 . 4 . 5 ). Under the on the frame 1 overlying roof 9 is the transversely and longitudinally displaceable lifting device 10 arranged.

The hollow box-shaped, rigid frame 1 can be designed as half-timbered or solid or combined construction. This frame shape allows the side of the longitudinal axis leading down frame parts a very stable and at the same time lightweight design.

The recoveries 6 can have a different shape in the upper area than in the lower area and can be combined. The vehicle can also be built without recoveries.

The frame 1 encloses a free working space 11 ,

The vehicle points in the area of working platforms 2 ; 3 a width up to 3.10 m. In the area of recoveries, the width can be reduced to about 2.50 to about 2.70 m. As a result, the vehicle may have a length of about 26 m.

4 shows the vehicle with one side unfolded side wall in working position. The unfolding of the upper and lower side wall part takes place 4 ; 5 by means of one or more lifting cylinder (s) 15 or other devices, so that the upper side wall part 4 is obliquely exposed and the lower side wall part 5 remains in vertical position. In this position, an optimal work is possible because the entrained rails and work equipment are in close proximity to the installation site and always in a vertical position. In addition, it is also possible to work without any problem in this position in platform / station areas as well as on other side obstacles (LS signals etc.). The lateral introduction of the equipment and the material is possible by pulling up the side wall.

In 5 the transport position of the vehicle is shown, in which case the two side wall parts 4 ; 5 can be easily pulled in towards the center of the vehicle. This offers the advantage that the lower side wall part, if necessary, can have a greater width and the vehicle still remains profile-free during transport. If a narrow side wall is sufficient, the vehicle can be implemented with vertical side wall. The variant with a narrow lower side wall part has the advantage that the lower edge of the side wall positioned higher in the unfolded position and thus better work in the field of obstacles or lateral load is even easier.
