Description

Equipment rack threshold

The invention relates to a device carrier threshold, in particular for Heißläuferund hard braking location of the track passing through rail vehicle comprising a track-side open trough or hollow sleeper with a U-geometry with side walls, from the longitudinal edges of support points for rail sections of the track, a cover and a preferably emanating from the cover for receiving at least one sensor arranged on the rail side.

A corresponding railroad equipment carrier sleeper is marketed by Tenconi S.A., Switzerland. Trained as trough sleeper track carrier threshold is intended for gravel and is closed all around. In order to drain liquid accumulating in the trough threshold, openings are present in the bottom wall. The bases extend over the entire width of the trough sleepers. As a result, the sensors for hot runner or hard brake location at a considerable distance from the rail and thus to the areas of the rail vehicle are arranged, which are to be checked.

Trough sleepers for other applications are z. B. from DE-A-43 15 200 or from DE-A-42 29 014 known. The corresponding trough sleepers are intended for receiving point closures. In this case, go according to DE-A-43 15 200 from the trough threshold resolved rail outlets. The rail-bound high-speed traffic is led on an increased scale on tracks, which emanate from a so-called slab track, so a ballastless construction. If a hot runner or hard brake location is to be performed on a slab track as Oberbauart, corresponding recesses are formed in the concrete, in which the sleepers of the track are integrated, which are suitable for receiving location systems, ie sensors. As a result, it requires special Ausschalungen in the production of slab track, whereby an additional time and associated costs arise.

The present invention is based on the object, a device carrier threshold of the type mentioned in such a way that a universal use, especially such is possible in a slab track, while also being achieved that the sensors required for positioning are optimally placed to to minimize the distance between sensor and locating range.

To solve the problem, the invention essentially provides that emanate from the side walls of the trough anchorages for pouring the trough threshold in a slab track that the bases are elastic, each base in two spaced from each one of the longitudinal wheels of the side walls outgoing Base part is divided, that the holder for the at least one sensor and / or the at least one sensor is extendable to between the support point parts, in particular extends directly to the rail portion, and that the trough threshold has a length, the width of the track supporting festivals Lane adjusted, in particular equal to the width.

Notwithstanding the prior art, a trough threshold is provided, which is designed to accommodate at least one sensor in particular intended for the hot rotor and hard brake location, with a pouring into a slab track is possible. For this purpose go from the side walls anchors, which are designed in particular as weldable to the side wall bolt. At the same time, it is ensured that the at least one sensor is located directly in the area the rail section can be positioned, so that the distance to the wheel to be checked or to the verifying axis of the railway vehicle passing through the track is optimized. This is made possible by the fact that the track section is supported on a dissolved rail support point, ie on a divided into two support point parts support point. The respective support point part extends in the region of one of the side walls of the trough threshold, so that the central region below the rail section freely accessible and thus in this area a sensor or a holder for this can be arranged.

Due to the teaching of the invention, there is the possibility that a sensor which is intended in particular for locating a hot run an axis, can be positioned immediately adjacent to the rail section between the Stützpunkteilen, so that the detection direction of the sensor vertically or nearly vertically, ie approximately parallel to the respective wheel to be measured runs. The distance to the rail section is thus smaller than the extension of the support point transversely to the track, viewed from outer edge to outer edge. In other words, a sensor can be positioned immediately adjacent to the rail foot, since the support does not cover the region of the trough threshold between the flange edges.

In particular, the sensor is an infrared sensor which is used for passive measurement of the axis heads, that is to say the ends of the axes. In this case, the sensor runs on the outside in the immediate area next to the rail foot.

Regardless of this, sensors can also be arranged on the inside, ie between the rail sections, which can be positioned in the desired position between the rail sections along the cover of the trough sleeper serving as a support to measure desired areas of the wheel or the axis of a rail vehicle passing through the rail to be able to. Thus, a Radreifenüberprüfung or temperature measurement of the wheel can be done directly in the region of the axis. Due to the length of the trough threshold, there is the advantage that liquid can flow out of the trough threshold to a sufficient extent. For this purpose, provision is made in particular for a cover which closes the respective end face of the trough threshold to be at a distance from the bottom wall of the trough sleeper and thus forms a gap from which liquid can flow. Furthermore, it is provided that the surface of the trough threshold is arranged parallel to the track, but the bottom wall inclined to the horizontal extending inclined in the slab track, whereby a gradient is generated, which facilitates the outflow of liquid. In side view results in a trapezoidal geometry.

In a further development of the invention, it is provided that the respective longitudinal edge of the trough threshold, at least in sections, has a flange running parallel or approximately parallel to the bottom wall, from which the support point part extends. Each support point part is designed as an elastic support, d. H. that an elastic rail support is provided, via which the forces acting on the track section forces are transmitted.

In order to ensure sufficient stability, it is further provided that the flange region supporting the rail is supported via at least one flat iron emanating from the side wall of the trough sleeper, which is slotted on the bottom side. This slotted area, which is designed as a claw, serves as additional anchorage in the concrete slab.

The trough threshold according to the invention in particular has a length L with 2400 mm <L <3200 mm, preferably of about 2600 mm, and / or a height H with 200 mm <H <250 mm, preferably H in about 220 mm, and / or a Inner width Bj with 330 mm <Bj <520 mm, preferably Bj in about 460 mm, and / or an outer width B _a with 360 mm <B ₃ <550 mm, preferably B _a in about 490 mm.

The trough threshold is designed as a hollow box made of sheet steel and welded, wherein the top has a cover with recesses for the holder or recording attachment of sensors. The front sides of the hollow box are closed, However, they have openings for cable entries and, as mentioned, outlets for drainage.

Further details, advantages and features of the invention will become apparent not only from the claims, the features to be taken from them-alone and / or in combination-but also from the following description of preferred embodiments to be taken from the drawings.

Show it:

Fig. 1 is a perspective view of a trough threshold and

Fig. 2 is a trough threshold in side view with sensors.

In Fig. 1, a trough threshold 10 is shown purely in principle and in perspective, which is designed as a device carrier threshold. The trough threshold has a hollow box shape with a U forming base body 12, which consists of sheet steel, wherein the side walls 14, 16 and bottom wall 18 may be welded together. The end faces of the base body 12 are closed by sheet-shaped covers 20, 22 which have cable openings 24, 26 in the region of their upper edge. Furthermore, the end plates 20, 22 are spaced from the bottom wall 18, so that a gap 28 is formed, which serves as a drain.

The corresponding trough threshold 10 is intended for pouring into a slab track. For anchoring go from the side walls 14, 16 weldable bolts 30, 32, 34. Optionally, from the bottom wall U-shaped steel bracket 36, 38 go out, which allow additional anchoring in the slab track.

From the upper longitudinal edges of the side walls 14, 16 extend parallel or approximately parallel to the bottom wall 18 extending flange-like portions 40, 42, which are additionally supported by flat iron 44, 46, 48, 50, which in turn connected to the side walls 14, 16 as are welded. The flat iron 44, 46, 48, 50 protrude while perpendicular to the plane defined by the side walls 14, 16 plane. The bottom wall side, the flat iron 44, 46, 48, 50 are fanned out and form claws 49, 51, which serve to anchor the trough threshold 10 in the slab track.

From the lateral flange-like portions 40, 42 base points go out 52, 54, 56, 58, which in turn elastically support rail sections 60, 62, which are sections of a track. The support point parts 52, 56 and 54, 58, respectively, constitute an elastic support, as it is in the track, but is divided and pulled apart, so that one can speak of a dissolved rail support.

Each support point part 52, 54, 56, 58 consists of a fin plate part 66, 68, 70, 72, which is supported on an elastic intermediate plate 74, 76, 78, 80, which in turn extends directly or indirectly from the flange-like portion 40, 42 , In the usual way, the ribbed plate parts 66, 68, 70, 72 secured to the flange-like portion 40, 42 via unspecified screws. The rail sections 60, 62 are held down by clamping clamps emanating from the ribbed plate parts 66, 68, 70, 72. Thus, the support point portions 52, 56 and 54, 58 are each, as it were, quasi an elastic rib plate assembly for securing the rail portions 60, 62.

The trough threshold 10, ie the base body 12 is covered by a cover 82 having openings, some of which are exemplified by the reference numerals 84 and 86. The cover 82 with the openings 84, 86 serves for the attachment of measuring devices 88, 90, which are shown purely in principle in Fig. 1. In this case, it can be seen that the measuring device 88 can be positioned directly next to the rail section 60, ie its foot, so that an optimal alignment of the sensor (s) of the measuring device 88 can take place for a rail vehicle or its axles and wheels passing through the track. The sensors are located immediately adjacent to the rail section 60, 62 between the support point portions 52, 54, 56, 58, which do not constitute a hindrance. By means of corresponding measuring devices 88, 90 or sensors, in particular the temperatures of regions such as axle or wheel region of a rail vehicle passing through the track measured, so in particular to make a hot rotor and hard brake location.

Since the rail sections 60, 62 are supported on the support point parts 52, 54, 56, 58 only in the edge region of the trough sleeper 10, the intermediate space is thus freely accessible, so that at least one sensor or one directly in the region of the respective rail sections 60, 62 Measuring device can be arranged. This in turn leads to the advantage that the measuring device can be positioned very close to the areas of the vehicle passing through the track in order to be able to carry out the required measurements.

The trough threshold 10 preferably has a length of about 2600 mm and a height of preferably about 220 mm. The inner clearance of the side walls 12, 14 is preferably about 460 mm, whereas the distance between the outer surfaces of the side walls 14, 16 should preferably be about 490 mm. By this dimensioning a device support threshold is provided, which is adapted to the thresholds of the track, so that the track conditions are not adversely affected by the trough threshold 10.

In Fig. 2, the trough threshold 10 is shown in principle in side view, so that correspondingly the same reference numerals are used for the same elements.

On the track sections 60, 20 is a chassis of a rail vehicle comprising an axle 92 with wheels 94, 96. Furthermore, 10 sensors 98, 100, 102, 104 are shown on the trough threshold to the axis 92 or areas of the axis 92 and the wheels 94, 96 can measure. The sensors 98, 100, 102, 104 are, in particular, infrared sensors with which passively the temperatures of desired regions of the rail vehicle, i. H. whose chassis are measured.

In the exemplary embodiment, the respective axle head 108 of the axle 92 is measured with the sensors 98, 104. For this purpose, the sensor 98, 104 is positioned such that the detection angle of the sensor 98, 104 is oriented vertically or almost vertically, ie vertical projection of the axis head 106, 108, the measuring field of the sensor 98, 104 intersects. The immediate positioning of the sensor 98, 104 in the region of the rail section 60, 62 or its foot is possible in that the support point is dissolved, that is, divided into the support point parts 52, 54, 56, 58 extending in the side wall regions of the trough threshold 10.

Between the rail sections 60, 62, the inner regions of the wheels 94, 96 or the axis 92 measuring sensors 100, 102 can be arranged on the trough threshold 10, which emanate from brackets or the cover 82 of the trough threshold 10. If the detection angle of the sensors 100, 102 is not variable, the area to be measured can be detected by adjusting the sensors 100, 102 to the rail sections 60, 62 to the appropriate extent. With regard to the sensors 100, 102, it is also possible to position them directly in the region of the rail sections 60, 62, provided that the detection angles are designed accordingly.

The length of the trough threshold 10 corresponds in particular to the width of a slab track so that liquid can flow unhindered over the slit 28 from the trough sleeper 10. In addition, it is possible to align the bottom wall 18 inclined to the horizontal in order to produce a slope to the gap 28 out. By contrast, the flange-like sections 40, 42 can run horizontally.

However, the invention is not abandoned when the trough threshold 10 is longer or shorter than the width of a slab track. Regardless of this, the gap 28 having end wall 20 should project either laterally in front of the slab track or pass flush or approximately flush in a longitudinal side of the slab track.
