Definitions

• the invention relates to a fastening arrangement with a device carrier on a steel-framed rail vehicle.
• Fasteners are known from the prior art that prevent a container from completely falling into the underground area, for example from the CN 216 805 418 U , the CN 207 045 333 U , or also the CN 203 601 276 U .
• the invention is therefore based on the objective of providing a fastening arrangement for a device carrier on a steel-framed rail vehicle, which allows the detachable fastening of the device carrier directly to a car body of a rail vehicle and offers a particularly high level of safety against the device carrier falling off in the event of a failure of the detachable fastening.
• a fastening arrangement comprising a device carrier and at least one longitudinal beam of a rail vehicle
• the longitudinal beam comprises a plurality of vertical bores arranged linearly and equidistantly on a horizontal projection of the longitudinal beam
• the device carrier is directly attached to at least one of the bores with releasable fastening means
• a bracket is releasably attached to two further bores, wherein the bracket encompasses a section of the device carrier so that in the event of a failure of the releasable fastening means the device carrier is held by the bracket, and wherein the bracket has a projection which prevents the releasable fastening means of the device carrier from falling off.
• This offers the advantage of being able to attach a device carrier to a rail vehicle in such a way that, on the one hand, the device carrier is prevented from falling off if the mounting hardware becomes loose, and on the other hand, the mounting hardware itself is also prevented from falling off. Furthermore, the invention offers the advantage of being able to position a device carrier according to the spacing of the holes and also to subsequently change the mounting location, since the rail vehicle does not need to provide any additional features, such as weld-on tabs, etc., apart from the holes.
• a rail vehicle which has at least one longitudinal beam with a plurality of, on a
• the horizontal section of the longitudinal beam comprises linearly and equidistantly arranged vertical bores.
• a device carrier is attached to these bores by means of detachable fasteners, such as screws.
• a bracket is also detachably attached to these vertical bores, with the bracket's attachment point located next to the bores used for mounting the device carrier.
• This bracket is designed to encompass a section of the device carrier, ensuring that if the device carrier's attachment fails, the carrier remains supported by the bracket.
• the bracket features a projection extending along the longitudinal axis of the device carrier's fasteners. This prevents the device carrier from falling off if one of its fasteners becomes loose, as the projection on the bracket blocks that fastener.
• the invention provides for equipping the rail vehicle with at least one longitudinal beam, which includes vertically arranged holes in a line along a horizontal section of the longitudinal beam, spaced equidistantly.
• This can be easily implemented in steel-framed vehicles where such longitudinal beams are manufactured as sheet metal bending components. Before the bending process, in addition to producing the necessary sheet metal cutout, the holes can also be drilled – a process that can be readily automated.
• Longitudinal beams commonly used in steel rail vehicles typically have a Z-, G-, or S-shaped cross-section, making it easy to create a horizontal section into which the vertical holes can be drilled.
• Vehicles constructed of lightweight metals can also utilize the present invention, particularly since the required shape can be easily integrated into a lightweight metal profile.
• other mounting methods for equipment carriers are also available for such vehicles, for example, via sliding nuts guided in C-rails.
• Typical equipment carriers are cuboid in shape. It is advantageous to equip the equipment carrier with rod-shaped extensions and to attach it to the longitudinal beam using these extensions. In this way, a bracket can grip each of these rod-shaped extensions and hold the equipment carrier in place if its fastenings are released.
• equipment carriers can be equipped with four rod-shaped projections, each secured with a bracket.
• more than one bore can be used for the detachable fastening of the equipment carrier; for example, two adjacent bores can each be used to create a screw connection. In this way, a secure connection to the longitudinal beam can be ensured, particularly with heavy equipment carriers.
• the bracket is preferably designed with a substantially U-shaped cross-section, such that one of the legs of the U-shaped cross-section can be detachably fastened to the longitudinal beam, and that the other leg of the U-shaped cross-section forms a shape which prevents the detachable fastening means of the device carrier from falling off.
• the function of the bracket can be realized by a simple sheet metal bending part, on which holes for screw fastening are typically made.
• the present invention is particularly advantageous for use with equipment carriers that are to be arranged below the underframe of a rail vehicle, i.e., so-called underfloor containers.
• equipment carriers that are to be arranged below the underframe of a rail vehicle, i.e., so-called underfloor containers.
• a multitude of devices such as batteries, power converters, water tanks, compressors, etc., are arranged below the underframe, and their falling off during operation must be prevented under all circumstances, as this could even lead to derailment of the rail vehicle.
• Equipment carriers can also be attached to the roof of a rail vehicle using the arrangement presented here. However, the typical design of longitudinal beams in the roof area complicates practical implementation.
• a key advantage of the present invention lies in the ease with which the mounting position of a device carrier can be subsequently changed. This requires only the removal of the device carrier's fastening elements and the associated brackets. In contrast, typical fastenings known from the prior art require modification of fixed mounting points, which usually necessitates extensive cutting, welding, and painting work.
• the position of the fasteners, especially the holes on the device carriers may deviate slightly from the intended position, so that mounting on the This is made more difficult by the longitudinal beams.
• the fastening arrangement according to the invention is advantageously applicable not only to equipment carriers but also to other components typically arranged on the underframe of a rail vehicle, such as the equipment skirts used to improve aerodynamics.
• FIG. 1 shows an exemplary and schematic mounting arrangement for a device carrier. It depicts a section perpendicular to the longitudinal axis of a longitudinal beam 2 of a rail vehicle in the area of the mounting position of a device carrier 1.
• the shown section of a rail vehicle includes an external longitudinal beam 2 with part of the vehicle floor and part of a device carrier 1, which incorporates a mounting rod.
• the equipment carrier 1 is typically attached to the longitudinal beams 2 of a rail vehicle by at least four attachment points.
• the longitudinal beam 2 shown is made of sheet steel and has a substantially S-shaped cross-section.
• a portion of the longitudinal beam 2 is designed as a horizontal projection 3 in which a plurality of vertical bores are arranged linearly and equidistantly parallel to the longitudinal axis of the longitudinal beam 2.
• the equipment carrier 1 is directly attached to two adjacent bores by means of detachable fasteners 4.
• the fasteners 4 are designed as screw connections, with an expansion sleeve 8 provided for each screw connection, allowing the use of longer screws at this critical, highly stressed connection point.
• a bracket 5 is detachably attached to the longitudinal beam 2 at adjacent bores, i.e., following and leading from the fasteners 4. This is achieved by means of fasteners 6, which are also designed as screw connections.
• the bracket 5 encompasses a section of the device carrier 1, so that if the detachable fasteners 4 of the device carrier 1 fail, the bracket 5 holds the carrier in place.
• the bracket 5 thus provides a fall-prevention device for the device carrier 1.
• the bracket 5 has a projection 7 that extends transversely to the longitudinal axis of the fasteners 4 of the device carrier 1. This prevents the fasteners 4, which are designed as screw connections, from falling off if they loosen.
• the bracket 5 therefore also provides fall-prevention for the fasteners 4.
• the device carrier 1 is first attached to the longitudinal beam 2, and then the bracket 5 is moved into its mounting position and connected to the longitudinal beam 2 by the fasteners 6. This ensures that the device carrier 1 is secured before the Mounting the bracket 5 provides optimal access to the fastening means 4 of the device carrier 1, so that conventional tools, especially conventional torque wrenches, can be used.
• Fig. 2 This shows an exemplary and schematic mounting arrangement for a device carrier in an outward-facing view. It is the mounting arrangement from Fig. 1 depicted, with the direction of view opposite to that from Fig. 1 The view is directed outwards. In particular, the gripping of the bracket 5 around a section of the device carrier 1 is evident. This section of the device carrier 1 is designed as a rod-shaped projection with a flattened area at the contact point with the longitudinal beam 2. Furthermore, a fastening element 6 of the bracket 5 and the projection 7 of the bracket 5 are visible in this view.
