Description

(1) The invention will be elucidated in more detail in the following.

(2) FIG. 1 shows in cross-section a line section 1 for the operation of electrically driven rail vehicles 19, with a track 2, which exhibits two parallel rails 3a, 3b, with a contact line 5, borne by an insulator 4, said contact line being arranged on one side of the track 2 in a spatial region 6 extending parallel to the rails 3a, 3b, wherein the contact line 5 is intended to supply current-collectors 20 of the electrically driven rail vehicles 19 with current and to support said current-collectors from underneath, and wherein the contact line 5 and the insulator 4 bearing the contact line 5 are intermittently interrupted or not interrupted.

(3) A support device 8, which is non-functional for the power supply of the rail vehicle, is arranged on the other side of the track in a second spatial region 7 extending parallel to the rails 2, said support device being intended to support current-collectors 20 of the electrically driven rail vehicles 19, see FIG. 7 and FIG. 8, from underneath without supplying them with current. The surfaces of the contact line 5 and of the support device 8 which are intended for supporting the current-collectors 20 are situated in a plane 9, the separations 10a, 10b of which, measured perpendicular to the plane 9, from the first rail 3a, adjacent to the contact line, and from the second rail 3b of the track 2 are equal.

(4) The support device 8 may have been constructed in a single part or in multiple parts and may consist, for instance, of solid material or of a hollow section. In particular, a support device 8 that is hollow inside may, performing additional functions, accommodate or bear devices 12 supplied with current. Electrical leads, data lines, data-processing devices, control devices, pressure sensors, optical sensors or other sensors, as well as electric lighting, enter into consideration in particular as electrical or electronic devices 12 suppled with current which are arranged on the support device 8. Sensors may provide, in particular, firstly, measured data relating to the line section 1, secondly, measured data relating to the rail vehicle 19 and the running behavior of the rail vehicle 19, and also, thirdly, measured data relating to hazardous situations. An example of the first case is the detection of damage to devices pertaining to the line section 1; an example of the second case is the detection of the position, speed and vibrational behavior of the rail vehicle 19; and an example of the third case is the detection of an obstacle on a railroad crossing.

(5) FIG. 2 and FIG. 3 show, from above, the line section 1 with a switch. The contact line 5 and the insulator 4 bearing the contact line 5, and also the support device 8, are intermittently interrupted. Movable support devices 11 replace these in the interruption. This guarantees that the supporting of the current-collectors 20 is uninterrupted in the case of both switch positions. The permanent supporting of the current-collectors 20 is indispensable at relatively high speeds. In the case of the switch position shown in FIG. 2, the branch line is traversed; in the case of the switch position shown in FIG. 3, the main track is traversed. The movable support devices 11 are preferably each supported so as to be capable of being moved horizontally about a pivot.

(6) FIG. 4 shows the line section 1 with at least one base plate 13. The line section 1 exhibits regularly recurring mounting points 14 arranged on the at least one base plate 13, which are intended for fastening the insulator 4 bearing the contact line 5, for fastening the rails 3a, 3b, and for fastening the support device 8. Regularly recurring mounting points 14 may also have been provided for the fastening of further parts, in particular for the protective covers 15 shown in FIG. 7. The parts fastened at mounting points 14 may have been fastened to the base plate 13 with the aid of fastening meansfor instance, screws or dowels. In equivalent manner, a mounting point 14 may also have been formed in such a way that the part to be fastened takes up a designated, fixed position on the base plate 13 without fastening meansfor instance, by sinking into a recess of the base plate 13 or by being supported on the base plate 13. In the case of multi-part base plates 13, it is crucial that the parts of the base plate 13 take up fixed positions, predetermined relative to one another, so that the aggregate thereof is equivalent to a single-part base plate 13.

(7) FIG. 5 shows the line section 1 with a road section 17 intersecting it. The surface of the road section 17 is located at the same height as the upper side of the rails 3a and 3b. The track section 1 exhibits two movable support devices 11 arranged parallel to the rails 3a and 3b, which can each be moved in the vertical direction by lifting devices 16. FIG. 5 shows the lifting devices 16 and also the movable support devices 11 in the operative position which enables the line section 1 to be traversed by a rail vehicle 19, see FIG. 7 and FIG. 8.

(8) FIG. 6 shows the line section 1 represented in FIG. 5, wherein lifting devices 16 and also the movable support devices 11 are in the inoperative position which enables the line section 1 to be crossed by a road vehicle.

(9) FIG. 7 shows the line section 1 in a circular tunnel 18.

(10) The base plate 13 here is in two parts, consisting of a first part 13a, forming a sidewalk, and a lower part 13b, bearing the track. The two parts 13a, 13b take up a defined, fixed position with respect to one another. As a result, it is ensured that dimensional tolerances between the protective cover 15a mounted on the first part 13a and the protective cover 15b mounted on the second part 13b are minimized. Depending upon the type of construction, the base plate 13 may have been subdivided further. For instance, the first part 13a shown in FIG. 7 may have been subdivided further into an upper part, forming the sidewalk, and a base part, bearing the sidewalk. Such a subdivision may be advantageous, particularly when a usable free space is to be formed between the sidewalk and the base part, or when different materials are to be combined. Deviating from the representation in FIG. 7, such a free space may provide room for the contact line 5 and for the insulator 4 bearing the contact line, so that the sections of the base plate 13 delimiting the free space also perform the function of a protective cover 15. A factor common to all possible configurations is thatin advantageous manner in terms of safety engineeringthe facilities utilized by people, in particular the sidewalk, the contact line 5 representing a danger to people, and the insulators 4 and protective covers 15 averting this danger are standardized parts with, at all times, the same positions and separations relative to one another.

(11) Optionally, the protective cover 15a mounted on the first part 13a of the base plate 13 additionally assumes the function of a step which can be stepped on, via which the sidewalk constituted by the first part 13a of the base plate 13 can be reached from the traveling way. The protective covers 15a, 15b have been designed in such a way that the contact line 5, constituted here by a third rail, cannot be reached directly, and accordingly the danger of contact by people is ruled out. The shape of the current-collector 20 of the rail vehicle 19 has been adapted to the shape of the cavity formed by the protective covers 15a, 15b. By virtue of the extended separation of the contact line 5 from the rails 3a and 3b and also from the rail vehicle 19, it is possible to use higher voltages and/or current intensities which simplify the operation of high-speed trains.
