Abstract

Vehicle for carrying out construction work in the track area of rail traffic, the maintenance vehicle having an internal work space which has a load-bearing frame and side walls, a lifting device / load suspension device being arranged in the ceiling area, characterized in that in the area of the side walls (1) or Frame (2) or other parts firmly connected to the vehicle, at least one device (3) is arranged, which establishes a connection between these parts and the hoist (4) / load suspension device (6) and a load (5) attached to it.

Description

The invention relates to a vehicle for carrying out construction work in the railway track area, wherein a device for moving loads is arranged in this maintenance vehicle with an internal working space.

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 posters are used for this purpose, which use bugle to issue timely danger reports. 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 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.

A vehicle is known for the maintenance of a track, with two spaced apart in a vehicle longitudinal direction rail bogies and with two by drives in a normal to the vehicle longitudinal direction transverse direction distanced side walls for limiting a direction open to the track, for a Performing maintenance work space provided, wherein each side wall of a - with respect to a vertical - upper wall portion and a lower wall portion is composed, wherein the lower wall portion by a drive relative to the upper wall portion is adjustable in height ( DE 20 2009 014 493 U1 ).

Furthermore, a vehicle for carrying out construction work in the railway track area, wherein the vehicle has a hollow box-shaped, rigid frame and two working platforms, which rest on two rail bogies and enclose a free in the direction of the track area working space, the vehicle between the rail bogies 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 fixed to the vehicle frame with a continuous joint or a series of joints and is connected via a second continuous joint or joint row with the lower side wall portion ( DE 20 2010 004 856 U1 ). The side walls and / or the upper fixed frame have at least one receiving device for rails on the longitudinal sides.

All maintenance vehicles have in common that load-carrying devices, if any, are arranged only in the roof rack area, so that heavy components, in particular rails, can only be positioned very limitedly and with little precision. In the event of an excessive camber, precise positioning of the loads in the track or in the side wall bracket is not possible at all.

The object of the invention is to be able to position heavy loads in the area of the working space of the maintenance vehicle exactly at any desired location even when the track is too high.

This is inventively achieved in that
in the region of the side walls or the frame or other parts fixedly connected to the vehicle, at least one device is arranged which establishes a connection between these parts and the hoist / load-carrying means and a load attached thereto.

The device designed to be adjustable in length, wherein the longitudinal adjustment is continuously or step-shaped.

The Längsverstellbarkeit is to be realized by means of a cylindrical drive, in particular a hydraulic cylinder or a pneumatic cylinder or a mechanical adjusting device, in particular a threaded rod or a ratchet or a rope or chain hoist with pulley.

The device is attached by means of a hinge on the side wall and designed to be vertically and / or horizontally pivotable.

The device may be detachably or fixedly arranged on the side wall. The side wall relative to the vehicle axle is designed to be movable.

In this case, the attachment point of the device on the side wall to the vehicle frame and / or to the track is designed to be horizontally and / or vertically displaceable or pivotable. The device has a load holding point, which is equipped with a brake and / or a drive. This makes it possible to lower the load without having to use the hoist of the vehicle.

At the same time the device has the function of the rail support and is able to take over the load of the object (eg the rail) in the extended state. This can z. B. several rails are positioned one above the other on the side wall.

Advantages of the invention:

• - Even in curved areas with elevations an exact positioning of the load (rails) on the superstructure or on the side wall is possible with a tilt of the vehicle.
• - The positioning of the load (rails) is possible in curves in the lateral edge areas of the interior.
• - The load is controlled in every situation, which reduces the risk of accidents.
• - Several devices can be arranged on each side of the vehicle.
• - Due to the release or free pivoting of the device on the vehicle sides working with it is very variable possible.
• - A detachable or longitudinally movable device allows objects of different lengths to be optimally moved and positioned.
• - A vertically pivoting device makes it possible to properly adjust their length in the unloaded condition and then to achieve the exact positioning solely by lowering the load by means of the hoist mounted on the ceiling, without having to change the length of the device in the loaded state again.
• - For movable, hinged or sliding side walls also a further freedom of movement is possible, the exact positioning the load by extending or retracting the side wall again improved.
• - Arranging a brake or a drive at the load-holding point allows a precise lowering of the load without having to move the hoist.
• - The ergonomics of the work to be done and safety of the employees is improved by such a device.
• - Damage to the car or the moving objects is avoided.
