Definitions
- Median crossing systems consist of two guide sleeper lines, each of which can be swiveled horizontally around a fixed point on a circular path.
- the guiding threshold lines in turn consist of several guiding thresholds.
- These guide thresholds each have a roller that is vertically displaceable. To pivot the guide sleeper strands, the rollers are moved vertically downward with each individual guide sleeper, so that the guide sleepers are mounted on the rollers and can be moved easily. The vertical displacement of the rollers is usually done pneumatically or hydraulically these days.
- Corresponding pumps or compressors must be made available for this. Since the median strip transfer systems are often built more than 100m long, these compressors and / or pumps are so large today that they have to be accommodated in pump houses along the streets.
- the task therefore is to provide a median crossing system make, which does not have the disadvantages of the prior art.
- the pressure generating units become vertical Moving the rollers and driving the means for releasable connection of the two threshold lines and the drives for the rollers within the Guiding thresholds housed.
- These thresholds have according to the ongoing Barriers off a New Jersey profile. It is surprising to those skilled in the art that succeeds in all the aggregates required for the respective drives and the control of the To accommodate median crossing system within the respective guiding thresholds.
- the rollers are preferably driven by a hydraulic or pneumatic cylinder vertically shifted.
- All hydraulic or pneumatic cylinders are preferred in one Leitschwellenstrang operated with a pressure generating unit, the Hydraulic and / or pneumatic cylinders are preferably connected in parallel, so that if one cylinder fails, the other cylinders cannot function properly is affected.
- the hydraulic or pneumatic cylinders are advantageously designed such that the guide thresholds vertically even if a hydraulic or pneumatic cylinder fails can be moved.
- This embodiment of the invention Median crossing system remains fully functional.
- the drive of the rollers is an electric motor with an electric magnetic brake.
- This embodiment has the advantage that the magnetic brake constantly dissipates heat, which also causes ice formation Condensate in the air lines of the pneumatics or an increase in the viscosity of the Oil in the hydraulic lines is reduced or avoided.
- FIG. 1 shows a median strip transfer system with two guide threshold lines.
- Figure 2 shows the connection between two guide thresholds.
- FIG. 3 shows a means for connecting two guide threshold lines.
- FIG. 4 shows a further means for connecting two guide threshold lines.
- FIG. 5 shows an arrangement of the units within a guide threshold.
- FIG. 1 shows a median strip transfer system 1 with two guide threshold lines 2, 3.
- the threshold lines 2, 3 consist of several thresholds 5, which are interconnected. These guide thresholds 5 are connected via a shortened guide threshold 7 to a fixed point 8, about which they can also be pivoted horizontally, as shown.
- Each threshold 5 has vertically displaceable rollers 6. When the rollers 6 are shifted downwards, the guide clamps 5 and thus the entire guide tie string can be moved horizontally on a circular path around the fixed point 8. After the guide sleeper strands have been moved, the rollers are moved vertically upwards and the guide sleeper rests on the ground with its frame or other supports. The rollers are moved vertically with a hydraulic cylinder.
- At least one guide threshold has a drive 9 with which the The threshold line can be moved vertically.
- This drive is preferably an electric motor that is equipped with an electromagnetic brake.
- each guide threshold is preferably equipped with a measuring wheel, with which the distance that the respective threshold has traveled can be measured can.
- the guiding thresholds are constructed as a frame construction, which with a Is coated.
- the guiding thresholds have a so-called New Jersey profile.
- a guardrail is about 5.8 meters long and has a weight of at least 1100 kg.
- the guiding thresholds are four Rubber buffers stored.
- the rubber buffers face wet asphalt at least a coefficient of friction of 0.75.
- Figure 2 shows the connection between two guide thresholds in several sections.
- two guide thresholds are connected with two means 4, 12 and braced together.
- the means 4, 12 are arranged at the level of the frame 17 and should be attached as far out as possible on the guide threshold.
- the means 4 is a screw
- the means 12 is a tube.
- the pipe is arranged horizontally and its longitudinal axis is at a right angle to the longitudinal axis of the guide sleeper. The pipe is pressed together by the screw and thus the screw and pipe are prestressed. In the present case, the preload is 100 kN.
- the tube is dimensioned in terms of its length, its diameter, its wall thickness and the material from which it is made in such a way that it can absorb 126.6 kJ of kinetic energy and is deformed in the process.
- the person skilled in the art understands that the tube can also be dimensioned such that it can absorb significantly more or substantially less kinetic energy. Since the pipe is deformed after a severe impact, it must be replaced afterwards.
- the guide sleepers In the upper area, the guide sleepers have a further screw connection 18, but which is not biased. Above that in the top of the guardrail are the Guide thresholds through two rectangular tubes 19, 20, which are inserted into each other are connected.
- the tubes 19, 20 are dimensioned so that the tube 20 in the tube 19 has horizontal play.
- the sheets 21, 22 have horizontal elongated holes.
- FIG. 3 the connection between two guide threshold lines 2, 3 is shown.
- the guide threshold strands are connected or braced at the end 10 by means 11, 16.
- the bolts 13, 16 are located completely within the guide sleeper strand 2 and the vertically displaceable latch 15 is raised such that its lower end 24 is located above the edge 25.
- the bolt 13 is pushed at least so far into the slotted sleeve 26 that the nose 14 of the bolt 13 is no longer below the bolt 15.
- the bolt 15 is lowered until it almost rests on the bolt 13, and then the bolt 13 is retracted until it rests with the nose 14 on the bolt 15 and the bolt is pretensioned with at least 200 kN.
- the bolt 13 and the bolt 15 are driven hydraulically.
- the bolt 16 is inserted into the sleeve 27. This However, the bolt is not tightened.
- FIG. 4 shows the same device for connecting and bracing the two guide threshold strands 2, 3, except that the bolts 16 and 13 have a common drive in this case.
- FIG. 5 shows the arrangement of the units within the guide threshold lines 2, 3.
- the lifting cylinders 29 and the locking cylinders 31, 32 are driven by the hydraulic pumps 30. All units are housed within the guiding thresholds and thus well protected against frost and destruction.
- the median crossing system is easy to install because the road does not have to be torn open to lay the pressure lines. There are no roadside buildings that pose a safety risk.

Abstract
Description
- jeweils aus mehreren durch mehrere Mittel miteinander verbundenen Leitschwellen bestehen, die jeweils vertikal verschiebbare Laufrollen aufweisen;
- jeweils an einem Ende jeweils mit einem Fixpunkt verbunden sind;
- jeweils unter dem Einfluß mindestens eines Antriebs um den jeweiligen Fixpunkt horizontal schwenkbar sind;
- an dem jeweils anderen Ende mit einem Mittel lösbar miteinander verbindbar sind.
Diese Anordnungen sind sehr teuer und haben den Nachteil, daß die Straße aufgerissen werden muß, um die Leitungen zwischen den Pumpen und/oder Kompressoren zu verlegen und daß das Mittelstreifenüberleitsystem durch die langen Leitungswege sehr frostanfällig ist. Darüber hinaus ist die Wartung dieses Mittelstreifenüberleitsystems kompliziert und aufwendig. Ein weiterer Nachteil ergibt sich dadurch, daß das Pumpenhaus ein Sicherheitsrisiko für den Verkehr darstellt. Schon mehrfach sind Kraftfahrzeuge mit den Pumpenhäusern kollidiert sind und haben dadurch die Pumpen und/oder die Kompressoren und die Steuerung des Mittelstreifenüberleitsystems zerstört.
