Description

[0001] This invention relates to a handrail device for rail vehicles, particularly for rail vehicles with end driver's cabs. The invention also includes a rail vehicle having such a handrail device and a method for operating such a handrail device. Particularly, the invention includes a dual-position handrail-pedal combination.

[0002] The available space at the corners of the front area (or, as used, "multiple front areas") of a rail vehicle with an end driver's cab is limited by the contours of various accessories, such as operating mechanisms for couplings or collision elements, or the front protrusions, to the extent that the layout of the pedals and handrails, which are common for shunting purposes in accordance with general standards (e.g., EN16116-1 or EN16116-2), and the resulting need for space to be reserved for handrails and shunting operator's pedals, cannot be achieved or can only be achieved with difficulty due to a lack of space.

[0003] This is particularly relevant to handrails and treads used for shunting purposes in the case of rail vehicles with end driver's cabs, which are associated with the entrance to the upper tread plane and are used for maintenance purposes, such as for cleaning the windshield.

[0004] This problem has not yet arisen, particularly in rail vehicles with end driver cabs used for shunting purposes, because rail vehicles with middle driver cabs have so far been used only for shunting purposes (with shunting operator's ramps conforming to EN16116-1).

[0005] Partially foldable handrails are used on certain types of freight cars (such as flatbeds). These handrails do not restrict the space for transporting goods when folded and ensure the possibility of grabbing by shunting personnel when unfolded. However, this principle cannot be used for rail vehicles with end driver's cabs.

[0006] The technical problem to be solved by the present invention is to provide a railing device and a method for operating such a railing device, which avoids the above-mentioned disadvantages and, in particular, ensures safe stopping.

[0007] This technical problem is solved by the railing device according to claim 1, the rail vehicle according to claim 6, and the method according to claim 15.

[0008] The guardrail device for rail vehicles, particularly end-cab locomotives, according to the invention comprises a guardrail element and a retaining element, the guardrail element being rotatably arranged (supported) in the retaining element about a rotation axis. Here, the retaining element is designed such that, whether externally mounted or as specified, it can be mounted in the front region of the rail vehicle, the rotation axis is vertically oriented.

[0009] Depending on its designated location on the rail vehicle, a handrail device can also be referred to as a "handrail device" or a "footrest device." For example, a lower handrail device can also be used as a footrest, and a higher handrail device can be used as a handrail. However, a handrail device can also be used as both a handrail and a footrest, for example, when a handrail device is used as a ladder rung.

[0010] The rail vehicle according to the invention includes a guardrail device according to the invention, wherein the retaining element is arranged in the outer region, particularly in the front region or in the region of the buffer, such that the axis of rotation is vertically oriented.

[0011] Therefore, the guardrail assembly is rotatably mounted on the rail vehicle and can thus be pivoted to different positions. Preferred positions are those for shunting purposes (“shunting position”) and those for maintenance purposes (“maintenance position”).

[0012] The guardrail device should be positioned in the shunting position such that it provides a handle for gripping during shunting operations, especially when using remote operation. It may also be advantageous if a shunting operator's board is present in the front area, with its boundary correspondingly defined on one side by the guardrail element of the guardrail device. Furthermore, for safety reasons, in the shunting position, the guardrail device should block access to the upper boarding plane. Such access is not necessary for shunting operations. In the shunting position, the guardrail device should be oriented such that it provides forward, buffer-facing protection and the additional possibility of occupying a safe shunting position. For this purpose, the guardrail device need not be located before the shunting operator's board (on the side facing away from the railcar), but rather must better define the boundary on the side facing the buffer (beside the shunting operator's board), as this effectively blocks access to the upper boarding plane positioned above the buffer.

[0013] Furthermore, the standard should ensure that there is sufficient free space above the shunting operator's pedal, i.e., that this space is not obstructed by pedal steps leading to the upper pedal plane. Implementation methods for achieving this are described below.

[0014] For maintenance purposes, the guardrail device should be able to be rotated from the shunting position to (and, if necessary, fixed in) the maintenance position, thereby opening access to the upper step. Simultaneously, for labor protection reasons, the guardrail device should provide handholds for climbing up and down, and forward, buffer-facing fall protection. For this purpose, it is preferable to rotate the guardrail element so that it is positioned in front of the upper step (on the side facing away from the railcar). It may also be desirable that the guardrail device, in the maintenance position, also provide additional step space in the free space of the shunting operator's step for safe and labor-protective access to the upper step. Such an implementation is described below.

[0015] A method for operating a guardrail device according to the invention on a rail vehicle according to the invention comprises the following steps. Here, the guardrail element (or said guardrail element) of the guardrail device can be secured by a locking element. These steps are:

[0016] - Loosen the fasteners on the railing components, especially by releasing the railing components from the other locking elements.

[0017] - Rotate the guardrail element around a vertical axis of rotation within the retaining element to another position, particularly from the maintenance position to the shunting position or vice versa.

[0018] - Secure the railing components with locking elements.

[0019] Therefore, the railing element, which can be a handrail or footrest, can be rotated to at least two positions in which it can be locked. These two lockable positions should be the shunting position and the maintenance position.

[0020] Other particularly advantageous designs and extensions of the invention are given by the dependent claims and the following description, wherein the claims in one class of claims may also be extended in a similar manner to the claims and descriptions in different classes of claims, and in particular, individual features in different embodiments or variations may be combined to form new embodiments or variations.

[0021] According to a preferred embodiment of the railing device, the railing elements comprise bars arranged parallel to and / or orthogonal to the axis of rotation. These bars should have a diameter greater than 2 cm but less than 10 cm so that they can be easily gripped or used as comfortable footrests. Preferably, at least a portion of the parallel bars are designed as handrails, and / or at least a portion of the orthogonal bars are designed as footrests. It should be noted that the orientation of the bars relative to a vertical axis of rotation (parallel or orthogonal) does not change when rotating about that axis, and the bars can still be used as handrails, footrests, or simply as a barrier. The bars are preferably hollow.

[0022] A preferred embodiment of the railing device includes at least two railing elements on opposite sides (or opposing sides) of a retaining element. Preferably, one railing element (relative to the axis of rotation) is above the retaining element, and the other railing element is below the retaining element. These railing elements are preferably rigidly connected to each other and are capable of rotating together about the axis of rotation. Alternatively, these railing elements may be unconnected and capable of rotating independently about the axis of rotation.

[0023] Preferably, these guardrail elements are twisted 90° relative to each other about the axis of rotation, or are capable of twisting 90°, that is, they are orthogonal to each other or can be oriented orthogonally to each other. Therefore, in the case of a connection, for example, it is feasible for the first (upper) guardrail element to laterally (towards the buffer) secure the shunting operator's platform and serve as a handrail, and the second (lower) guardrail element to forwardly secure the shunting operator's platform. The term "laterally" means that the plane of the guardrail element is vertical and parallel to the longitudinal axis of the rail vehicle, and the term "forwardly" means that the plane of the guardrail element is vertical and orthogonal to the longitudinal axis of the rail vehicle.

[0024] According to a preferred embodiment of the guardrail device, at least one guardrail element is lockable or fixable. For this purpose, the at least one guardrail element preferably has a locking element in the region of the axis of rotation or away from the axis of rotation. Thus, the guardrail element can be fixed in a preferred position, such as the shunting position and / or maintenance position mentioned above, thereby preventing unintentional rotational movement. This is for safe stopping or to ensure the provision of security. The locking element does not necessarily have to be part of the guardrail device. It is sufficient that the guardrail device is shaped at a predetermined location to be able to be fitted into or held by the locking element. For example, in a very simple case, the guardrail element may have a vertical tube end at the bottom, which can be fitted into a hole in a plate on the rail vehicle.

[0025] According to a preferred embodiment, the railing assembly is a steel pipe structure or a plastic pipe structure. Here, the pipe can be hollow or compact (i.e., a rod made of solid material). However, hollow elements are preferred because they have a lower weight while maintaining sufficient strength.

[0026] A preferred embodiment of the rail vehicle includes an end cab, wherein guardrail devices are installed in the area adjacent to and / or preceding the end cab, preferably in the area of ​​the rail vehicle's buffers. These buffers are preferably installed such that a shunting platform conforming to applicable standards, such as EN16116-1, can be installed between the end cab and the buffer platform. A preferred end cab locomotive for shunting operations includes a buffer system, an end cab, and a shunting platform located preceding the end cab and on the side of a first buffer system. Here, the shunting platform is arranged such that, with the buffer fully resiliently pressed in, the buffer plane is located in front of the shunting platform. Therefore, the space above the shunting platform, i.e., the space defined by the vertical projection of the shunting platform, is outside the free space of the first buffer system. The guardrail devices are preferably arranged on the rail vehicle such that, with the buffer fully resiliently pressed in, the buffer plane is located in front of the guardrail devices. Therefore, the guardrail devices are preferably located outside the free space of the rail vehicle's buffers.

[0027] According to a preferred embodiment of the rail vehicle, the guardrail element (or a single guardrail element) comprises bars parallel to and / or orthogonal to the axis of rotation (as described above). Preferably, at least a portion of the bars arranged parallel to the axis of rotation are positioned above the rail vehicle's buffer and designed as handrails. Also preferably, at least a portion of the bars arranged orthogonally to the axis of rotation are positioned below the rail vehicle's buffer and designed as footrests. When a person is standing on the shunting operator's platform, this area below the buffer is within the person's leg area; therefore, the footrest is advantageous when the person wants to climb to the upper plane. The guardrail above the buffer is within the person's arm area; therefore, a handrail is advantageous there.

[0028] A preferred embodiment of the rail vehicle includes a plurality of locking elements designed and arranged to releasably secure the railing elements of the railing assembly in predetermined positions. These locking elements do not necessarily have to be located on the railing assembly, but can be particularly arranged on the pedals. In a simpler case, the locking elements may be holes in the pedals into which the tubular ends of the railing elements can be inserted. Preferably, a portion of these locking elements is arranged to secure sections or portions of the railing elements away from the axis of rotation. This increases the leverage effect of the locking elements.

[0029] A preferred embodiment of the rail vehicle is designed with multiple locking elements such that the railing element can be secured in two different positions. These two positions preferably correspond to a rotation angle of at least 70° about the axis of rotation, and particularly preferably to a rotation angle of at least 80° about the axis of rotation. The two preferred positions are particularly torsional about 90° relative to each other about the axis of rotation.

[0030] A preferred embodiment of the rail vehicle also includes a footboard (e.g., for maintenance or shunting purposes), which is particularly located in the area of ​​the rail vehicle's buffer. The term "footboard" generally refers to a platform. If the footboard has railings or handrails, it may also be referred to as a "platform".

[0031] For example, the shunting operator's pedal may be arranged slightly laterally offset below the buffer, or the maintenance pedal may be arranged above or above the buffer or the impact element on the buffer. The pedal should be bounded (and thus particularly form a platform) by a guardrail element of the guardrail assembly on at least one side. The rail vehicle here includes preferably at least two pedals, such as the shunting operator's pedal and the maintenance pedal mentioned above, located in the area of ​​the buffer, which are jointly bounded on at least one side by at least one guardrail element of the guardrail assembly. The invention is particularly advantageous in such a layout because the rotatability of the guardrail assembly can provide alternating access or safety features. Preferably, the boundaries are defined by the guardrail element such that, in one position of the guardrail assembly, the guardrail element forms a barrier between the two pedals and is particularly situated in a vertically oriented plane, which, in the case of obstruction, is preferably oriented parallel to the longitudinal axis of the rail vehicle.

[0032] A preferred embodiment of a rail vehicle includes an upper pedal (maintenance pedal) above the buffer (e.g., above or above the buffer or the impact element of the buffer) and a lower pedal below the buffer (and slightly laterally offset), both pedals being defined on at least one side by at least one first (upper) guardrail element of a guardrail assembly. This first guardrail element extends beyond the upper pedal, preferably at least 70 cm, particularly at least 90 cm, or even one meter, so that it can be used as a guardrail and / or handle for both pedals.

[0033] Preferably, the first guardrail element is rotatable about a rotation axis to a first position (maintenance position), in which the first guardrail element allows access from the lower step to the upper step (or forms an entrance from the lower step to the upper step) and preferably additionally defines the boundary of the upper step as a guardrail on the side of the upper step facing away from the railcar. Furthermore, preferably, the first guardrail element is rotatable about a rotation axis to a second position (shunting position), in which the first guardrail element blocks the entrance from the lower step to the upper step and preferably additionally serves as a handrail for a person standing on the lower step.

[0034] A preferred embodiment of the rail vehicle includes a second (lower) guardrail element arranged in the height region between the two aforementioned treads and capable of serving as a guardrail and as a step or ladder. Preferably, this second guardrail element can be rotated about a rotation axis to a first position (maintenance position), in which it serves as a step / ladder from the lower tread to the upper tread and preferably additionally defines the boundary of the lower tread towards the rail vehicle's buffer. The second guardrail element can also be rotated about the rotation axis to a second position (shunting position), in which it defines the boundary of the lower tread on the side of the lower tread facing away from the rail vehicle. The second (lower) guardrail element mentioned herein is particularly advantageous in combination with the aforementioned first (upper) guardrail element. Especially when the two guardrail elements are each in a plane, they are twisted 90° relative to each other about the rotation axis. When the first (upper) guardrail element is oriented parallel to the longitudinal axis of the rail vehicle, the second (lower) guardrail element is preferably orthogonal to that longitudinal axis, and vice versa.

[0035] A preferred embodiment of the rail vehicle also includes a retaining interface for mounting the guardrail device on the rail vehicle's buffer. This retaining interface includes a retaining body with a component fixing area and a mounting area distinct from the component fixing area. The component fixing area is equipped with fixing elements and / or holes for mounting the component, and the mounting area is shaped to allow it to be secured to at least two fixing points on the buffer flange (sometimes referred to as the "buffer base plate") of the buffer using buffer bolts (typically commercially available bolts). This method optimally utilizes available space and thus meets shunting specifications.

[0036] One advantage of this invention is that it ensures the safe presence of personnel in the front area of ​​a railcar with an end driver's cab during shunting, particularly in conjunction with the simultaneous blocking of access to the upper tread plate for labor protection reasons during shunting operations. Another advantage, due to the movable nature of the barrier device, is that it ensures access to (climbing up and down) the upper tread plate during maintenance, particularly in conjunction with simultaneous forward fall protection in the buffer area. This allows standard locomotives to be converted from mainline locomotives (not specifically for shunting purposes) to those also suitable for shunting.

[0037] The invention will now be described in more detail again with reference to the accompanying drawings and embodiments. Here, the same parts in the different drawings are given the same reference numerals. The drawings are conventionally not drawn to scale. In the drawings:

[0038] Figure 1 shows a rail vehicle according to the prior art.

[0039] Figure 2 The image shows a rail vehicle with a preferred guardrail arrangement in a shunting position.

[0040] Figure 3 A rail vehicle with a preferred guardrail device in a maintenance position is shown.

[0041] Figure 4 Show Figure 2 The magnified part

[0042] Figure 5 A rail vehicle with a preferred railing device is shown relative to a person.

[0043] Figure 1 shows a front view of a rail vehicle 20 with an end driver's cab 25 and its buffer area according to the prior art, and a perspective view of the buffer area is also shown again for better overview. This is a typical design of the front end area of ​​a rail vehicle 1 with an end driver's cab 25. The buffer 21 and the front baffle 22 are clearly visible. For maintenance purposes, an upper step plane 23 is arranged on the buffer, which is accessible via foot pedals 24 on the side of the rail vehicle 20. Due to limited available space, there is no space here for a shunting operator's pedal conforming to EN16116, but only space for foot pedals and a step plane (neither of which conforms to EN16116).

[0044] Figure 2A rail vehicle 20 with a preferred guardrail device 1 in a shunting position is shown. A portion of the perspective detail of FIG1 can be seen here from a slightly different perspective. The preferred guardrail device 1 according to the invention is shown here, having a (first) upper guardrail element 2a and a (second) lower guardrail element 2b, which are rotatably supported opposite each other in a retaining element 3 (one above and one below the retaining element 3), so that the two guardrail elements can rotate about a vertical axis of rotation D (dashed line). In this example, to better understand the orientation of the guardrail elements 2a, 2b described below, it can be envisioned that the upper guardrail element 2a is fixedly connected to the lower guardrail element 2b by continuous rods, so that when the upper guardrail element 2a rotates, the lower guardrail element 2b rotates accordingly.

[0045] The rail vehicle 20 has a maintenance pedal 5 as an upper pedal and a shunting operator's pedal 6 mounted on a holding device 7 as a lower pedal in the front area. From the maintenance pedal 5, a person can, for example, reach the window of the driver's cab 25 at the end of the rail vehicle (20) to clean the window. During shunting operations, a person can stand on the shunting operator's pedal 6. This shunting operator's pedal conforms to the requirements of EN16116-2.

[0046] In this example, the maintenance pedal 5 is directly mounted on the buffer 21 via the retaining interface 8. Here, the retaining interface 8 is located between the buffer flange of the buffer 21 and the impact element (not shown in detail) and is secured there with buffer bolts.

[0047] The railing elements 2a and 2b of the railing device 1 are made of rods (or tubes), which are preferably hollow and preferably of steel tubular structure. In the case of the upper railing element 2a, these rods extend mostly parallel to the axis of rotation D, so they can be used well as handrails. In the case of the lower railing element 2b, these rods are mostly orthogonal to the axis of rotation D, so they can be used well as footrests.

[0048] The guardrail assembly 1 is positioned such that guardrail elements 2a and 2b define the boundaries of the two pedals 5 and 6 on at least one side of the two pedals. The guardrail assembly 1 can be rotated to a shunting position and a maintenance position and is fixed therein (see [reference]). Figure 4 ).

[0049] Figure 2 The guardrail assembly 1 is shown in the shunting position. In this position, the entrance from the shunting operator's platform 6 to the maintenance platform 5 is blocked by an upper guardrail element 2a, which also serves as a handrail for a person standing on the shunting operator's platform 6. A lower guardrail element 2b, positioned at a height between platforms 5 and 6, serves as a guardrail and defines the boundary of the shunting operator's platform 6 on the side of the platform facing away from the railcar 20.

[0050] Figure 3 and Figure 2 Correspondingly, the difference is that, in Figure 3 The middle guardrail device 1 rotates to the maintenance position. In the maintenance position, it is permissible to move from the shunting operator's platform 6 to the maintenance platform 5 because the upper guardrail element has now pivoted forward and defines the front boundary of the maintenance platform 5 (to prevent falling). Therefore, the passage between the shunting operator's platform 6 and the maintenance platform 5 is free, and the lower guardrail element 2b can be used as a step from the shunting operator's platform 6 to the maintenance platform 5 and additionally as a buffer 21 of the guardrail towards the railcar 20, defining the boundary of the shunting operator's platform 6.

[0051] Figure 4 Show Figure 2 A magnified local area. Here, in conjunction with... Figure 2 The locking element 4 is shown separately, by which the upper railing element 2a can be secured. The movable handrail formed by the upper railing element 2a can be locked in two positions: a shunting position and a maintenance position, thereby preventing unintentional rotational movement. When the lower railing element 2b is connected to the upper railing element 2a as described above via a rod, the lower railing element is automatically secured together with the upper railing element 2a by locking it. In a very simple embodiment, the locking element 4 can simply be a hole in the maintenance pedal 5. In this case, the railing assembly can be easily lifted, rotated, and the vertical rod of the upper railing element 2a can be inserted into the nearest hole for fixation.

[0052] In this example, there are two locking elements 4 so that the railing device 1 can be fixed according to... Figure 2 and Figure 3 Two different positions, with a 90° rotation angle between them.

[0053] Figure 5 The rail vehicle 20, shown relative to a person, has a preferred guardrail device 1 in shunting position A and maintenance position B, as in... Figure 2 and Figure 3 As shown in the diagram.

[0054] Finally, it should be reiterated that the embodiments and methods described in detail above are merely examples, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention. Furthermore, the use of the indefinite article "a" or "an" does not preclude the existence of multiple related features. Similarly, terms such as "unit" do not preclude the existence of related components composed of multiple sub-components that work together, which may, if necessary, be spatially distributed.
