Abstract

The lane guide section uses a number of guide kerbs (13) defining the different lanes, each provided by several abutting kerb elements (31), which can be adjusted via an integrated electrically-operated drive (33) and vertical rollers (34,35). A tensioning and locking device (32) is provided at one end of the guide kerb, with a tensioning element which extends longitudinally between two fixing points (4,14), embedded in the road surface at relatively spaced positions across the traffic lanes. <IMAGE>

Description

The invention relates to a guide threshold line according to the features in the preamble of claim 1.

Such a threshold line is part of the prior art through US Pat. No. 4,632,598. This guide sleeper string can only be moved in the transverse direction with the help of rollers driven by an electric motor. In this way it is possible to assign the same number of lanes to two directions of travel in the case of multi-lane traffic routes or, depending on the traffic volume, to assign a different number of traffic lanes. This is an advantage, for example, in the morning or evening rush hour traffic on major and minor roads in major cities.

Furthermore, it is known in the scope of US-PS 44 74 503, an articulated guide rail with the help of a special To move the laying wagon across to itself in order to be able to do justice to the traffic volume by changing the number of lanes.

Now there are traffic management problems, especially before and after tunnels or in the area of toll gates on multi-lane traffic routes (motorways), where it is not important to provide more lanes to keep rolling traffic as smooth as possible, but where several lanes in one a smaller number should be merged or at least one lane should be expanded into several lanes in a fan shape. This is e.g. necessary when tunnel tubes are blocked, when the ticket booths are not occupied at toll booths or when certain routes are blocked. In these cases, it was previously common for the guide sleeper strands to be shifted manually from their longitudinal direction in such a way that the traffic that, for example, rolled into two lanes was only directed into a tunnel tube instead of two tunnel tubes or was transferred from two tunnel tubes into a lane. A similar procedure was followed for the blocking of routes, where a route limitation is then opened at certain points and the traffic is directed from one side of the route limitation to the other side.

The expenditure of time and personnel associated with the implementation of control threshold lines or the additional installation is high. In addition, hazards to the people carrying out the implementation are not excluded, since the work must be carried out at least in the vicinity of traffic that continues to move.

Based on the prior art, the invention is based on the object of creating a guide threshold line, which, without endangering mechanics, allows traffic flows to be laterally diverted from specified lanes in certain traffic areas without the need for manual work.

This object is achieved according to the invention in the features listed in the characterizing part of claim 1.

The guide threshold strand according to the invention is basically clamped between two fixed points in its longitudinal direction. For this purpose, a tensioning and locking unit is incorporated into the guide threshold line at at least one end of the guide line. This tensioning and locking unit is designed so that it takes over the tensioning of the guide sill strand between the two fixed points on the one hand, but on the other hand also ensures the bottom-side locking of the guide sill strand at a fixed point that is let into the ground and can be run over by rolling traffic. If, therefore, the guiding sleeper strand is to be pivoted at an angle due to the local conditions, it is sufficient if a tensioning and locking device is arranged at one end and a stationary axis of rotation is located at the other end of the guiding sleeper strand. For the pivoting of the guide sill strand, the longitudinal tension between the fixed points is then released with the help of the tensioning and locking unit, the locking of the guide sill strand at the base-side fixed point is released and the guide sill strand is pivoted so that it rolls by motor around the axis of rotation until the intended next floor-side, by which Rolling traffic overrun fixed point is reached. Here, the guide threshold line is then locked again on the floor and braced in the longitudinal direction.

The formation of the guide sleeper line with a fixed axis of rotation at one end and with a tensioning and locking unit at the other end can, for example, be installed advantageously where the traffic has to be deflected laterally from one lane to another lane. This can be the case before or after tunnel tubes, before or after tollbooths or on multi-lane roads where the traffic must be transferred from one side to the other of an otherwise permanently installed roadway boundary. In this individual case, two guide threshold strands can form the wings of a gate that is opened in the closed guideway boundary. The one guiding threshold line is then pivoted in one direction and the other guiding threshold line in the other direction and re-fixed there.

However, the invention also opens up the possibility of providing tensioning and locking units at both ends of a guide threshold line, so that the fixed points on both ends of the guide line must then be able to be driven over by the rolling traffic if the guide line moves parallel to itself into another position of use becomes.

Of course, it is also possible within the scope of the invention to provide two or more displaceable guide threshold strands of limited length in the longitudinal direction one behind the other.

How many rollers a guide threshold line has and how many of the rollers are driven by an electric motor depends on the place of use and the respective local conditions.

The fixed points are designed in such a way that they not only ensure proper tensioning of a guide threshold strand Ensure the longitudinal direction and its local locking, but also ensure their function in cooperation with the tensioning and locking units in all seasons under all weather conditions.

The locking element assigned according to claim 2 to a tensioning and locking unit forms, in cooperation with a fixed point that can be run over by rolling traffic, to a certain extent an abutment which, together with the fixed point at the other end, ensures the tensioning of the guide threshold strand in the longitudinal direction and its local locking.

According to an advantageous development of the invention, according to claim 3, the locking element is provided on a guide body which is inevitably movable in the longitudinal direction of the guide threshold strand and which at the same time carries a lifting device for the locking element. The guide body can, for example, be positively guided along a base plate which is fixedly connected to the guide threshold line, with the aid of a threaded spindle which can be rotated by an electric motor. Pneumatically or hydraulically actuated cylinders are also conceivable, which shift the guide body in the longitudinal direction of the guide threshold line. The lifting device carried by the guide body can be of an electric motor, pneumatic or hydraulic design. It is able to couple and disengage the locking element with a fixed point.

Furthermore, according to the features of claim 4, it is advantageous that the fixed points that can be run over by the rolling traffic can only be influenced by a locking element. For this purpose, each fixed point has a cover plate as part of a clamping housing firmly anchored in the floor. This cover plate is so spring-loaded in the closing direction of the clamping housing that rolling traffic can easily pass the fixed point and stand on it. If a guide threshold line is to be locked on the floor, the locking element is moved vertically downwards using the lifting device. Here, the cover plate is displaced by the locking element against the restoring force. Then a longitudinal displacement of the guide body of the tensioning and locking unit takes place, with the result that the guide threshold strand is then tensioned between this fixed point and the fixed point at the other end (fixed axis of rotation or fixed point that can be rolled over by traffic).

So that the locking and unlocking positions are also correctly defined when moving a guide threshold line and reaching a new fixed point that can be run over by traffic, a sensor interacting with the cover plates is assigned to the locking element. The tensioning and locking unit is only activated when the correct locking position has been determined via this sensor.

In a preferred embodiment of the invention, the features of claim 6 allow the remote controllability of all movable devices. Remote control can be carried out from a central control center. Furthermore, the devices can also be connected to a computer. Via the program entered into the computer, it is then possible to shift the respective guide threshold line in the desired manner by pressing a button.

In view of the fact that the guide threshold line according to the invention is of such a limited length, for example 50 m to 100 m long, and a secure bracing between the end fixed points must always be guaranteed, a correspondingly stable design of the guide threshold strand according to the features of claim 7 proves to be particularly advantageous.

1 in FIG. 1 denotes a travel path boundary that separates two travel paths FW1, FW2 from one another. In the course of this guideway boundary 1, two guide threshold strands 2, 3 are incorporated, which can be pivoted about fixed vertical axes of rotation 4 in the transverse direction of the guideway boundary 1. In the extended operating position (closed lines) between the axes of rotation 4 and fixed points 5 which can be run over by the rolling traffic, the guide threshold strands 2, 3 are braced in the longitudinal direction and locked in position.

In the exemplary embodiment, the guide sleeper strands 2, 3 are pivoted about the axes of rotation 4 according to the arrows PF and locked at the fixed points 6 (dash-dotted lines) that the traffic from the lane FS1 of the guideway FW1 over the then open area between the two guide sleeper strands 2, 3 can be transferred to the lane FS2 of the route FW2.

Of course, the guide sleeper lines 2, 3 can also be pivoted in the other direction according to the arrows PF1 (dash-dot-dot line routing), so that the traffic from the lane FS1 of the route FW1 to the parallel lane FS3 and the traffic from the lane FS2 of the route FW2 can be transferred to the parallel lane FS4. In this case, the guide threshold strands 2, 3 are locked in the fixed points 7.

In addition, the guide threshold strands 2, 3 can be pivoted over the entire width of the travel paths FW1 and FW2 (dash-dot-dot-dot lines). You will then be locked in the fixed points 8. In this way, if necessary, both lanes FS1 and FS3 can be steered onto the parallel route FW2.

FIG. 2 shows a top view of a traffic area in front of four tunnel tubes 9, 10, 11, 12. The two routes FW1 and FW2, each with two lanes FS1, FS3 and FS2, FS4, are separated from one another by a route boundary 1. In the course of this guideway boundary 1, a guide sleeper line 13 is incorporated, which extends between a fixed axis of rotation 4 and a fixed point 14 that can be driven over by rolling traffic. Between the axis of rotation 4 and the fixed point 14, the guide threshold strand 13 is clamped in the longitudinal direction. Furthermore, the guide threshold strand 13 is locked in position at the fixed point 14.

Depending on the local conditions, for example when one of the tunnel tubes 9-12 is blocked, it may be necessary to control the traffic flow accordingly. In this case, the guide threshold line 13 is consequently shifted according to the arrows PF2-PF5 into one of the four avoidance positions around the axis of rotation 4 (dash-dotted lines) and anchored here via the fixed points 15-18 provided there.

It is also conceivable in the embodiment of FIG. 2 that, in the normal position, two guide threshold strands 13, 19 are arranged directly next to one another in the longitudinal direction behind the travel path limitation 1. The guiding threshold line 13 can then in the guideway FW1 leading into the tunnel tubes 9, 10 and the other guiding threshold line 19 in the guideway FW2 leading out of the tunnel tubes 11, 12.

FIG. 3 shows a top view of a guideway boundary 1 between two guideways FW1, FW2 and a guide threshold line 20 integrated into this guideway boundary 1, which can be shifted parallel to itself according to arrows PF6. The guide threshold line 20 is firmly clamped between two fixed points 21, 22 that can be driven over by rolling traffic and is locked at the fixed points 21, 22. Even in the transversely shifted operating position (dash-dotted lines), the guide threshold line 20 is clamped between two fixed points 23, 24 that can be run over by rolling traffic and is locked in position in these fixed points 23, 24.

According to the arrows PF7, PF8 and PF9, the guide threshold line 20 can of course also be shifted to the edge of the route FW1, between the two lanes FS2 and FS4 of the route FW2 or to the edge of the route FW2. In these operating positions, the guide threshold line 20 is then locked in the fixed points 25, 26 or 27, 28 or 29, 30.

The guide threshold line 2, 3, 13, 19, 20 used in the traffic areas according to FIGS. 1 to 3 is shown in more detail in FIGS. 4 and 5. It is composed of several guide thresholds 31, which are explained in more detail with reference to FIG. Take the guide threshold line 13 of FIG. 2 as an example.

At one end, the guide sill strand 13 can be pivoted about a vertical axis of rotation 4, while at the other end the guide sill strand 13 is provided with a tensioning and locking unit 32, which enables the guide sill strand 13 between the axis of rotation 4 and a fixed point 14-18 embedded in the floor and to lock the position.

Furthermore, 13 electromotive drives 33 are integrated in the longitudinal direction of the guide sleeper train, which drive vertically displaceable rollers 34. FIG. 5 also shows that a plurality of non-driven rollers 35 are provided in the longitudinal direction of the guide sleeper line 13, but can be displaced vertically by lifting devices 36. The lifting devices 36 can be formed by pneumatically actuated cylinders.

In the use position, the guide sleeper strand 13 lies directly on the floor 37, while the rollers 34, 35 are extended downward for displacement, and the frictional contact of the guide sleeper strand 13 with the floor 37 is thereby eliminated.

FIGS. 6 to 9 show an electric motor drive 33. Each drive 33 comprises two electric motors 38, which drive on rollers 34 via gears 39. In addition, pneumatically actuated lifting cylinders 40 are arranged between the electric motors 38, which extend the rollers 34 downward out of the guide sleeper strand 13 and can thereby lift it off the floor 37, so that it only rests on the rollers 34 and 35.

The tensioning and locking unit 32 which serves to tension a guide threshold strand 2, 3, 13, 19, 20 in the longitudinal direction and its respective local locking in the fixed points 5-8, 14-18 and 21-30 is shown in FIGS. 6, 10 and 11 remove. It is again explained using the guide threshold line 13 and the fixed point 14.

The tensioning and locking unit 32 initially comprises a guide body 41 which can be displaced in a positively guided manner in a groove 42 of a base plate 43 fastened in the guide sleeper line 13. The guide body 41 laterally carries a nut 44 which is penetrated by a threaded spindle 45. The spindle ends are rotatably supported in two bearing blocks 46 which are fastened on the base plate 43. The threaded spindle 45 is driven by an electric motor 47 via a gear 48 and a coupling 49. Depending on the direction of rotation of the threaded spindle 45, the guide body 41 is consequently displaced in one or the other direction in the groove 42 of the base plate 43.

A spherical locking element 50 can be displaced vertically in the guide body 41. The displacement takes place with the aid of a pneumatically actuated cylinder 51 which is fastened on the guide body 41. It can also be seen that a sensor 52 is arranged on the locking element 50.

In the position illustrated in FIGS. 4 to 6 and 11, the guide threshold strand 13 has just been displaced and the sensor 52 of the locking element 50 is oriented over the fixed point 14 for the purpose of determining the exact position. For this purpose, a cover plate 55 which is vertically displaceable against an elastic restoring force 54 is provided on the fixed point 14 which has a clamping housing 53 embedded in the floor 37.

If the sensor 52, in cooperation with the cover plate 55, has determined the exact position of the fixed point 14, the locking element 50 is moved downward by acting on the pneumatic cylinder 51, whereby the cover plate 55 is moved downward against the restoring force of the spring 54. The locking element 50 is at a height at which it is completely immersed in the clamping housing 53 (Figure 11, left half), the lifting movement is ended. For this purpose, the tensioning unit 32 is now activated, which shifts the locking element 50 transversely in the tensioning housing 53 until it is supported on the tensioning housing 53 in such a way that the guide sleeper strand 13 is tensioned in the longitudinal direction. The degree of tension is monitored by a force sensor 56 (FIG. 10), which is assigned to the gear 48.

If the position of the guide sill strand 13 according to FIG. 4 is to be removed, the guide sill strand 13 is first relaxed in the longitudinal direction until the locking element 50 lies exactly below the opening 57 which receives the cover plate 55. The pneumatic cylinder 51 is now acted upon and the locking element 50 is moved upward out of the clamping housing 53. The cover plate 55 follows the locking element 50 into a position (right half of FIG. 11) in which the cover plate 55 can again be passed over by the rolling traffic without problems.

Now the guide sleeper line 13 can be shifted about the axis of rotation 4 by first extending the rollers 34, 35 and then activating the electric motors 38. The guide threshold strand 13 now rolls into the intended pivot position and is locked there in the manner described above in one of the fixed points 15-18.

All movements are remotely controlled and / or programmed in a computer, so that no manual effort for the displacement, tensioning and locking of a guide threshold strand 13 is required.

The guide threshold line 13 according to FIGS. 4 and 5 has, in accordance with FIG. cross-sectionally trapezoidal, internally stiffened guide sleepers 31 with lateral drive-on legs 58 and coupling tabs 59 at the end. The guide sleepers 31 are stiffened by runners 60 which are U-shaped in cross section and open at the top (FIGS. 6 and 8). The runners 60 extend from areas below the slightly inclined drive-on leg 58 to approximately half the height of the guide thresholds 31. The end faces of the vertical runner legs are on the inner contour of the drive-on leg 58 and the flat side surfaces 62 that end on the drive-on leg 58 with a curved transition section 61 the guide thresholds 31 are positively adapted. They are also welded to the drive-on legs 58, the transition sections 61 and the side surfaces 62.

Above the guide sleepers 31 there are provided guide rails 63 which are open at the bottom and have a trapezoidal cross section, which are put over the guide sleepers 31 and are detachably coupled to them by screw connections 64. The angle of inclination of the flat side surfaces 62 of the guide sleepers 31 and 66 of the guide rails 63 with respect to the vertical is approximately 10 °. The guide bars 63 also have coupling tabs 65 for mutual connection.
