Description

Conversion device from tip rail to basic rail

The invention relates to a conversion device from a point rail to a basic rail fixed on a rail backing plate (such as a ribbed plate), which includes a turnout sliding bed plate mounted on a rail backing plate on a self-supporting (such as a sleeper) or a fixed track and At least one roller element from the fixture which is the support of the tongue rail.

A corresponding device is cited from EP-A-0 964 100. In order to be able to mount the roller arrangement comprising a roller element and a fastening device universally, it is provided that the roller elements are adjustable not only in the height direction but also in the distance from the base rail.

Disclosed by EP-B-0 904 457 is a switching device for a switch rail, which presses on the roller plane of the turnout sliding bed plate determined by the roller pair, wherein the front roller of the roller pair is adjusted lower than the rear roller, and at least one The rollers are arranged on eccentrics configured as eccentric roller axes, so that adjustment of the roller elements in their height is possible. Equally, the roller pair itself is also made adjustable relative to the basic rail. For this purpose, the roller sets protrude from corresponding fastening devices.

Known roller arrangements are connected to the ribbed plate in such a way that they move together. In this way, especially when the lifting shaft is guided into the base rail and thus into the ribbed plate, a collision with the tongue rail occurs.

The technical problem underlying the invention is to design a device of the type mentioned at the outset in such a way that the roller elements are unambiguously assigned to the base rail, but at the same time it must be ensured that no uncontrollable impact-causing forces can be applied to the switch rail.

According to the invention, the problem is solved essentially by the fact that the fastening device is detachably connected to a pad in the rail backing, which in turn is connected to the rail backing via an elastic intermediate layer.

According to the invention, the fastening means comes from a pad which is elastically connected to the rail backing plate (e.g. a ribbed plate) so as to be loose to a certain extent, which allows it to Not transmitted to the pad and thus not to the fixing of the at least one roller element. At the same time, no special fastening measures are required for the liner, since it is fastened together with the rail backing plate.

It is especially provided that the roller elements pass through the switch slide deck, resulting in a compact unit. And according to EP-B-0 904 457, the fastening device of roller element is arranged next to the turnout sliding bed plate, therefore additional fastening measures are required. In addition, the ribbed plate must also be made wider than usual.

In a further embodiment of the invention it is provided that the pad is so prestressed in the direction of the support that the pad is mounted on the support independently of the vertical position of the rail backing plate, which can be achieved with fastening elements (such as bolts) This is done through the pads so that the pads are attached to supports (such as sleepers) or fixed rails. At the same time, this method also secures the rail backing plate (eg ribbed plate) since the liner is connected to the rail backing plate via the elastic intermediate layer. The connection between the liner and the rail backing plate takes place in particular by vulcanization.

Alternatively, it is also possible to fasten the liner to the support by means of rail backing plates in such a way that the liner is continuously pressed against the support without the liner itself being penetrated by fastening elements such as bolts. For this purpose, the lining can be fluidized into the rail backing plate such that in the non-installed state the underside of the liner protrudes beyond the underside of the rail backing plate. If the rail backing plate/liner unit is fixed on the support (such as a sleeper) or the fixed track, then the liner is introduced by a force in the direction of support, and if the rail backing plate is applied to the lifting shaft, the rail The backing plate is adjusted vertically so that the pad is pressed flat against the support.

In addition, the liner is provided with an elongated groove extending in the longitudinal direction of the rail backing plate, in the inner section of which at least one roller element extends rotatably. It is also provided in particular that the length of the groove is such that at least two roller elements adjacent to each other are arranged in the longitudinal direction of the rail backing plate. In this case, the axes of the roller elements are generally parallel or approximately parallel to the longitudinal axis of the base or tongue rail.

Along the groove, but also along its longitudinal edge, fixed brackets are provided, so that the fixing device can be adjusted along the longitudinal direction of the rail backing plate, so as to ensure that the distance from the basic rail can be adjusted to the desired range, so as to ensure that the switch rail is obtained. best support.

In order to achieve a compact arrangement, it is also proposed that the switch slide bed is provided with a recess which at least partially surrounds the liner. For this purpose, the switch slideway has in particular a U-shaped geometry, wherein the side legs of the switch slideway run along the longitudinal edges of the pads and in particular outside them, while their transverse sides run directly along the base rail.

Further details, advantages and characteristics of the invention are to be obtained not only from the claims and their described features (in themselves and/or in combination), but also from the following description of the illustrated preferred embodiments Know.

The accompanying drawings show:

The outline drawing of the first implementation form of Fig. 1 tip rail to basic rail conversion device;

Figure 2 is according to Figure 1, but there is no device for the switch sliding bed and roller device;

The vertical sectional view of device shown in Fig. 3 Fig. 1;

The outline drawing of the second implementation form of Fig. 4 switch rail to basic rail conversion device;

Shown in Fig. 5 Fig. 4, but do not have the device of switch slide bed plate and roller device.

The first embodiment of the device for adjusting the switch rail 11 to the base rail 10 shown in FIGS. , the turnout sliding bed plate is detachably installed on the rib plate 12 through the rod spring elements 16,18. This is known from the structures explicitly published as in WO-A-94/05858. Here, the switch slide bed 14 is simultaneously used to fix the basic rail 10 and is supported on the section 20 of the foot 22 of the basic rail 10 here. The section 24 of the foot 22 of the base rail 10 which is remote from the switch slide bed is usually fixed via a clamping spring 28 , for example by clamping bolts 26 . Reference is made in this regard to sufficient known structures or selected structures.

The switch slide plate 14 has a U-shaped geometry, wherein its transverse limb 30 runs directly along the base rail 10 and bears on the bottom surface on the section 20 of the rail foot 22 . In the longitudinal direction of the ribbed plate 12 of the switch slide plate 14 , ie in the form of lateral feet 32 , 34 extending transversely to the rails 10 , 11 , a pad 36 of the ribbed plate 12 is surrounded by an elastic intermediate layer 38 Connected to the rib plate 12. In particular, the connection of the liner 36 to the rib plate 12 is vulcanized.

The liner 36 has a longitudinal groove 42 whose width is selected such that rollers 44 , 46 extending from a fastening device 48 connected to the liner 36 can extend therein. To this end, the liner has along the sides of the slot 42 receiving locations (eg holes) 50, 52 in which the fastening means 48 can be fastened with bolts 54, 56. At that time, the bolts 54, 56 pass through the elongated holes 58, 60 existing on the fixing device 48, so that the fixing device 48 and thus the roller elements 44, 46 can be steplessly adjusted relative to the basic rail 10, because the elongated holes 58, 60 The distance from the notches or holes 50 , 52 in the pad 36 is designed such that its distance relative to the base rail 10 can be varied steplessly.

Since the liner 36 is connected to the rib plate 12 through the elastic intermediate layer 38, it is loosened to a certain extent, thereby ensuring that the liner 36 is continuously supported on the support (such as a sleeper) or a fixed track, so that the roller element 44 The fixing means 48 of , 46 occupy a definite position and therefore do not or substantially do not move together with the ribbed plate 12 .

In the region of the transverse edges of the ribbed plate 12, bolts 40, 62 pass through to connect it to the support device.

The bolts 40 , 62 then pass through the inserts 64 , 66 made of plastic that are provided in the elongated holes, so that depending on the geometry and orientation of the recesses of the bolts 40 , 62 for each insert 64 , 66 , it is possible to The ribbed plate 12 is adjusted in the direction of its longitudinal axis. Reference can also be made in this regard to the many known structures, for example in DE-A-4406105.

FIGS. 4 and 5 show another embodiment of the sliding switch from the switch rail to the base rail, wherein the same elements have been given the same reference numerals as in FIGS. 1 and 3 .

The difference between the embodiment shown in Figures 4 and 5 and the embodiment shown in Figures 1 to 3 is that the bolts 40 fixing the rib plate 12 are not spaced apart from the gasket 36, but are accommodated and fixed together with the gasket 64. The interior of the gasket 36 of the device 48 passes through, whereby the gasket 36 can be prestressed by means of the bolts 40, which makes the gasket 36 continuously flat on the floor, independent of whether the ribbed plate 12 is subjected to floor forces (For example, due to the use of lifting shafts) effect. The ribbed plate 12 is likewise fastened together by means of the bolts 40 since the liner 36 is connected to the ribbed plate 12 via the intermediate layer 38 .
