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 threshold line according to the features in the preamble of claim 1.

Such a threshold line counts through US-A-46 32 598 on the prior art. This threshold line can be powered by an electric motor Castors are only moved in the transverse direction. In this way it is possible for multi-lane Traffic routes both directions the same number of Lanes or depending on traffic assign a different number of traffic lanes. This is for example in the morning or evening Rush hour traffic on inland and arterial roads from Big cities an advantage.

It is also known within the scope of US-A-44 74 503 an articulated threshold line with the help of a special To move the laying carriage across to itself, order in this way by changing the number of Lanes also do justice to the respective traffic volume to be able to.

Now there are traffic management problems, in particular before and after tunnel tubes or in the area of tollbooths on multi-lane traffic routes (motorways) where it the provision of more lanes is not important, in order to keep rolling traffic as smooth as possible, but where multiple lanes on a smaller number merged or at least one lane fan-shaped to be extended to several lanes. This is e.g. when tunnel tubes are blocked, when not occupied of ticket booths at toll booths or at blocking certain routes. In these It was previously common for cases that the guiding threshold lines were manually shifted from their longitudinal direction, that, for example, rolling on two lanes Traffic only in one tunnel tube instead of in two tunnel tubes steered or by two tunnel tubes into a laxative Lane is transferred. It was similar when roadways are blocked, where then on certain Make a track boundary open and traffic from one side of the route boundary to the other side is directed.

The one with the implementation of the threshold lines or the additional installation related time and personnel Effort is high. There are also threats to the People who carry out the implementation are not excluded, since work continues at least near rolling traffic must be carried out.

The invention is based on the prior art Based on the task of creating a guiding threshold line, which allows it to be done at short notice without endangering fitters, Traffic flows from given lanes on certain Distract traffic areas laterally without this manual activities required.

According to the invention, this object is achieved in those listed in the characterizing part of claim 1 Characteristics.

The guide threshold line according to the invention is fundamental between two fixed points in its longitudinal direction tense. To do this, there is at least one end of the guide threshold line a clamping and locking unit in the Integrated threshold line. This clamping and locking unit is designed so that on the one hand the Bracing of the leading threshold line between the two Fixed points, but also the bottom side Locking the guide threshold line on one Fixed point guaranteed, which was embedded in the floor and can be run over by the rolling traffic. So should due to the local conditions of the leading threshold line be pivoted at an angle, it is sufficient if on one end of a tensioning and locking device and is at the other end of the guide threshold line there is a fixed axis of rotation. For panning the Leitschwerschstrangs is then using the tensioning and Locking unit the longitudinal tension between the fixed points canceled, the locking of the guide threshold line loosened at the fixed point on the floor and the guide threshold line rolling around the axis of rotation like this pivoted far until the intended next floor-side, fixed point that can be run over by rolling traffic is reached. This is where the leading threshold line is again locked on the floor and braced in the longitudinal direction.

The formation of the guide threshold line with a stationary Axis of rotation at one end and with a clamping and Locking unit at the other end, for example, there installed with advantage where the traffic from a Lane is laterally deflected to another lane got to. This can be before or after tunnel tubes, before or after toll stations or on multi-lane roads Case where traffic is targeted from one to the other other side of an otherwise permanently installed guideway limitation must be transferred. In this individual case can, so to speak, two leading threshold strands Form the wing of a gate in the closed guideway boundary is opened. The one threshold line is then in one and the other threshold line pivoted in the other direction and re-fixed there.

The invention also opens up the possibility of both Ends of a guide threshold strand tensioning and locking units to be provided so that the fixed points at both ends of the guardrail strand from the rolling Traffic must be passable when the guardrail line parallel to yourself in a different position is shifted.

It is of course also within the scope of the invention possible two or more relocatable guide threshold lines of limited length in the longitudinal direction one after the other to provide.

How many rollers a guide threshold line has, and how many of the castors are driven by an electric motor depends on the location and the respective local Circumstances.

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

That assigned according to claim 2 a clamping and locking unit Interlocking element forms in cooperation with a fixed point that can be run over by rolling traffic a kind of abutment that together with the Fixed point at the other end is the tensioning of the guide threshold line lengthways and its local locking ensures.

According to an advantageous development of the invention is the locking element according to claim 3 one inevitably in the longitudinal direction of the guide threshold line movable guide body provided, the at the same time a lifting device for the locking element wearing. The guide body can for example on a Base plate firmly connected to the guide threshold line be positively guided along, with the help of one of an electric motor rotatable threaded spindle. Are conceivable but also pneumatically or hydraulically actuated Cylinder, which the guide body in the longitudinal direction of the Relocate the threshold line. That of the guide body carried lifting device can be electromotive, be designed pneumatically or hydraulically. she is in able to lock the locking element with a fixed point couple and uncouple.

Furthermore, it is according to the features of claim 4 It is advantageous that those that can be run over by the rolling traffic Fixed points only through a locking element can be influenced. For this purpose everyone points Fixed point a cover plate as part of a fixed in Floor anchored clamping housing. This cover plate is spring-loaded in the closing direction of the clamping housing that the rolling traffic easily the fixed point can run over and stand on it. Should be a threshold line be locked on the floor, so it will Locking element using the lifting device vertically moved down. Here the cover plate by the locking element against the restoring force shifted. Then there is a longitudinal displacement of the Guide body of the clamping and locking unit with the Result that then the leading threshold strand 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) is.

So when relocating a guiding threshold strand and reaching it a new fixed point that can be run over by traffic the locking and unlocking positions are also correctly defined are, is the locking element according to claim 5 a cooperating with the cover plates Assigned sensor. Only when this sensor is in perfect condition Lock position has been determined activation of the tensioning and locking unit.

The features of claim 6 allow in a preferred embodiment the invention the remote controllability of all movable Facilities. The remote control can be operated by one from the central control center. Furthermore, the Facilities but also connected to a computer be. It is via the program entered into the computer then possible by pressing the appropriate button Guide threshold strand in the desired manner relocate.

In view of the fact that it is the inventive Guiding threshold strand around such a limited Length is, for example 50 m to 100 m long, and always a secure tension between the fixed points must be guaranteed a correspondingly stable design of the guide threshold line according to the features of claim 7 as special advantageous.

1 in FIG. 1 denotes a travel path limitation, separates the two routes FW1, FW2. in the The course of this travel boundary 1 is two Guiding threshold strands 2, 3 incorporated around the fixed vertical axes of rotation 4 in the transverse direction of the travel path limitation 1 are pivotable. The threshold lines 2, 3 are in the extended operating position (closed Lines) between the axes of rotation 4 and the rolling Traffic traversable fixed points 5 in the longitudinal direction tense and locked in place.

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

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

Furthermore, the threshold lines 2, 3 over the entire Width of the travel paths FW1 and FW2 can be pivoted (Dash-dot-dot-dot lines). Then you will locked in the fixed points 8. This way, at Requires both lanes FS1 and FS3 on the parallel Route FW2 can be steered.

In Figure 2 is a traffic area in plan view illustrated in front of four tunnel tubes 9, 10, 11, 12. The both routes FW1 and FW2, each with two lanes FS1, FS3 or FS2, FS4 are due to a travel path limitation 1 separated from each other. In the course of this route limitation 1 is a Leitschwellenstrang 13 incorporated, the between a fixed axis of rotation 4 and one of the rolling traffic passable fixed point 14 extends. Between the axis of rotation 4 and the fixed point 14 is the Guide threshold strand 13 braced in the longitudinal direction. Furthermore is the threshold line 13 at the fixed point 14 locked in position.

Depending on the local conditions, for example at Locking one of the 9-12 tunnels may be required to direct the flow of traffic accordingly. In consequently, the leading threshold strand 13 becomes corresponding arrows PF2-PF5 in one of the four alternate positions shifted about the axis of rotation 4 (dash-dotted lines Lines) and here via the fixed points provided there Anchored 15-18.

It is conceivable in the embodiment of FIG. 2 also that in the normal position two guide threshold strands 13, 19 immediately next to each other in the longitudinal direction behind the path limitation 1 are arranged. The leading threshold line 13 can then in the tunnel tubes 9, 10 leading guideway FW1 and the other guide threshold line 19 in the route leading from the tunnel tubes 11, 12 FW2 can be pivoted.

FIG. 3 shows a travel path limitation in plan view 1 between two routes FW1, FW2 and one in this guideway limitation 1 integrated threshold line 20, which is parallel to itself according to the arrows PF6 itself is relocatable. The leading threshold strand 20 is between two fixed points that can be run over by rolling traffic 21, 22 firmly clamped and at the fixed points 21, 22 locked. Even in the transversely shifted operating position (dash-dotted lines) is the leading threshold line 20 between two vehicles that can be run over by rolling traffic Fixed points 23, 24 braced and in these fixed points 23, 24 locked in position.

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

The one in the traffic areas according to FIGS. 1 to 3 leading threshold line 2, 3, 13, 19, 20 is shown in more detail in FIGS. 4 and 5. It is made up of several using FIG. 12 guide thresholds 31 explained in more detail below. The guide threshold line 13 from FIG. 2 is an example accepted.

At one end, the threshold line 13 is vertical Pivot axis 4 pivotable while at the other end the guide threshold strand 13 with a tensioning and locking unit 32 is provided, which makes it possible to the guide threshold line 13 between the axis of rotation 4 and an im Floor fixed point 14-18 braced and locked in place.

Furthermore, in the longitudinal direction of the guide threshold strand 13 electromotive drives 33 incorporated, the vertical drive displaceable rollers 34. The also shows 5 shows that in the longitudinal direction of the guide threshold strand 13 several non-driven rollers 35 are provided, which, however, can be displaced vertically by lifting devices 36 are. The lifting devices 36 can be pneumatically actable cylinders are formed.

The guiding threshold line 13 is in the operating position immediately on the floor 37, while to relocate the Rollers 34, 35 are extended downward and thereby the frictional contact of the threshold line 13 with the Floor 37 is lifted.

Figures 6 to 9 show an electric motor drive 33. Each drive 33 comprises two electric motors 38, which drive off on gears 39 on rollers 34. Furthermore are pneumatic between the electric motors 38 actuatable lifting cylinder 40 arranged which the rollers 34 extend downwards out of the guide threshold line 13 and thereby lift it off the floor 37, so that it only rests on the rollers 34 and 35.

The tensioning of a guide threshold strand 2, 3, 13, 19, 20 in the longitudinal direction and its respective local Locking in fixed points 5-8, 14-18 and 21-30 serving Tensioning and locking unit 32 is shown in FIGS. 6, 10 and 11. It is in turn based on the leading threshold line 13 and the fixed point 14 explained.

The tensioning and locking unit 32 initially includes one Guide body 41, which is in a groove 42 in the guide threshold strand 13 fastened base plate 43 positively guided is relocatable. The guide body 41 carries laterally a nut 44, which is 45 is enforced. The spindle ends are in two bearing blocks 46 rotatably mounted, which is fixed on the base plate 43 are. The threaded spindle 45 is driven by an electric motor 47 via a gear 48 and a clutch 49. Depending on the direction of rotation of the threaded spindle 45 consequently the guide body 41 in one way or another Direction in the groove 42 of the base plate 43 shifted.

A spherical locking element is in the guide body 41 50 vertically displaceable. The relocation takes place with the help of a pneumatically actuated cylinder 51, which is fixed on the guide body 41. Furthermore it can be seen that a sensor on the locking element 50 52 is arranged.

In the illustrated in Figures 4 to 6 and 11 Position, the guide threshold strand 13 has just been shifted and the sensor 52 of the locking element 50 orientates itself over the fixed point 14 for the purpose of precise position determination. For this purpose, there is a recess in the floor 37 Clamping housing 53 having fixed point 14 a against an elastic restoring force 54 vertically displaceable Cover plate 55 provided.

Has the sensor 52 in cooperation with the cover plate 55 the exact position of the fixed point 14 is determined by Actuation of the pneumatic cylinder 51 the locking element 50 moves down, causing the top plate 55 moved downward against the restoring force of the spring 54 becomes. The locking element 50 is in one Height at which it is completely immersed in the clamping housing 53 (Figure 11, left half), the stroke movement completed. For this purpose, the clamping unit 32 is now activated, which the locking element 50 transversely in the clamping housing 53 shifted until it on the clamping housing 53 so supports that the Leitschwellenstrang 13 in the longitudinal direction is tensioned. The degree of tension is determined by a Force sensor 56 monitors (FIG. 10) the transmission 48 assigned.

If the position of the guide threshold line 13 according to FIG. 4 are lifted, so there is first relaxation of the threshold line 13 in the longitudinal direction until that Locking element 50 exactly below the cover plate 55 receiving opening 57 is located. Now the Pneumatic cylinder 51 acted upon and the locking element 50 moved upward from the clamping housing 53. The Cover plate 55 follows the locking element 50 up to a position (right half of Figure 11) in which the Cover plate 55 again perfectly from the rolling traffic can be driven over.

Now the Leitschwellenstrang 13 can thereby Axis 4 are shifted that first the rollers 34, 35 extended and then the electric motors 38 activated will. The threshold line 13 now rolls into the provided pivot position and is there in the above described locked in one of the fixed points 15-18.

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

The threshold line 13 according to FIGS. 4 and 5 has according to FIG. 12, a plurality of detachably placed one after another, trapezoidal in cross-section, inside stiffened guide sleepers 31 with side loading legs 58 and end coupling tabs 59. The Guide thresholds 31 are of U-shaped cross-section, skids 60 open at the top are stiffened (FIGS. 6 and 8). The runners 60 extend from areas below the slightly inclined loading leg 58 to about half Height of the guide thresholds 31. The end faces of the vertical Skid legs are attached to the inner contour of the loading leg 58 as well as of the drive-on leg 58 with a curved Transitional section 61 final flat side surfaces 62 of the guide thresholds 31 are positively adapted. They are also with the ramps 58, the Transitional sections 61 and the side surfaces 62 welded.

Above the guide thresholds 31 are open, Trapezoidal hoods with cross-sections 63 provided that slipped over the guide thresholds 31 and detachable with these by screw connections 64 are coupled. The angle of inclination of the flat side surfaces 62 of the guide thresholds 31 and 66 of the guide rails 63 to the vertical is about 10 °. The main pillars too 63 have coupling tabs 65 for mutual Connection.
