Description

The present invention relates to a two-guide rail crossing device that forms part of a mobile electric energy conduction device with a floor for a vehicle.

This can be a problem with the two induction rails of a road or warehouse vehicle with power via the floor, but can also be a problem with the two induction rails of the induction device of the floor energizer of any vehicle's kinetic energy. . The target electric vehicle is, for example, a land vehicle on a road, but may be a rail vehicle. The invention applies in particular to urban shared transport vehicle traffic roads that are automatically guided by electric propulsion, and these vehicles can be of the rail or tire type. However, the present invention is not limited to this preferred application.

This type of electric vehicle runs in particular on a track that is arranged to satisfy all the vehicle needs for induction and power supply. The track thus includes at least one guide rail as well as one or more straight conductor tracks used for powering the vehicle floor, which guide rail may have at least one of these conductor tracks.

Obviously for safety reasons, access to the conductor track is interrupted by a linear protective material protruding from the top. These protective materials are arranged on the surface, for example, and at the same time when the power feeding device is embedded in the floor, the level and the surface of the floor are matched.

An energization device cooperating with the flooring device is installed in the vehicle. This device has at least one current-carrying component provided with one or more current-carrying flanges that are in sliding contact with a straight conductor path with a protective material floor that moves under these surface straight-line protection members during operation. included.

The energization component is inserted at the first energization position on the main line and reappears only at the end of the main line. In general, it can only be taken out during energization in exceptional circumstances where human safety is threatened.

The object of the present invention is to intersect two traffic tracks with a floor-mounted electrical energy energization device and a guidance device, that is, the two guidance rails can have at least one electrical energy conductor track.

Some problems are raised when these two travel tracks must cross. The two guide rails must be interrupted at the crossing plane while continuing the guidance of the vehicle or the current-carrying device, just like a straight conductor track. In addition, the intersection must be able to pass without interference of the components energized by electrical energy.

In order to solve these technical problems, the present invention includes two guide rails each including one guide rail on which a vehicle induction device or an induction device of a floor-mounted electric energy conduction device runs by power feeding via the floor. It is possible to produce the intersection of the running tracks.

Each of these guide rails is locally interrupted in a region that coincides with these intersections occupied by core parts remote from the ends of the rail, thereby ensuring central support when the guide device is in transit.

According to the invention, the guide rails interrupted on both sides of the core part are free to pass through the lower part of the floor-mounted electric energy carrying device over a certain length, respectively from or before their interrupted ends. Therefore, the space vacated toward the floor presents an upper part in a cantilever state in which the length of this part is divided.

At least one of the guide rails may exhibit at least one conductor track on at least one side of the flank, the conductor track being subsequently interrupted by the length of the portion of the cantilever from the core part at the adjacent portion of the corresponding flank Is done.

Furthermore, at least one of the guide rails can present at least one adjacent supply conductor, one of its faces constituting a transverse conductor track, so that the conductor track is a certain length before and from the core part. Suddenly interrupted.

The intersection according to the invention will now be described in detail with reference to FIGS. 1 to 6 corresponding to a preferred embodiment of the invention. The same elements shown in the various figures are given the same reference numerals.

FIGS. 1 to 4 show, for illustrative purposes, two traffic tracks 1 for vehicles powered via the floor, not necessarily, for example road vehicles, preferably automatically guided vehicles. It is.

Two traffic tracks 1 are installed according to the invention and in particular intersect in the region of intersection 2 illustrated in the enlarged view of FIG. These tracks 1 include a guide rail 3 that is used for guidance of the vehicle itself or guidance of its energized brace.

A preferred but non-limiting variant of this guide rail 3 that is compatible with the intersection 2 according to the invention is shown in FIG. 5 alone and in cross section.

The rail 3 is advantageous in that it is electrically insulating and mechanically strong and can be manufactured preferably by extrusion.

Through various actual methods, it is possible to obtain parts that utilize fiber reinforcement with the maximum strength in the extrusion direction.

However, if the part where the appearance appears is zero potential or there is no danger to people, the case of a metal rail may be envisaged.

For the embodiment shown, the rail 3 shows a body 4 whose overall cross-sectional shape is of the approximately triangular type. In order to save material while ensuring a sufficient strength against lateral stresses, the body 4 of the rail takes on the structure of a grooved box, which is thus separated, for example, by the inner wall 7. At the same time, it is preferred to include caskets 5 and 6 with two generally trapezoidal cross-sections on which the inner conduit means 8 of cylindrical cross-section rides.

The main body 4 of the rail is followed by the head of a solid section rail 9, which can also be called a mushroom shape, towards the top. In the example shown, this head has two lower belly bellows 10 that extend upward and incline, and at the same time incline and incline at the same time. The cross section of the trapezoid whole shape with the traveling path 11 is exhibited.

In this way, this is a guide rail for a vehicle or a power brace guidance device that may include two guide rollers inclined in a V-shape that will run on two corresponding ramps 11 of the rail head 9. Is available as

BEST MODE FOR CARRYING OUT THE INVENTION

Near the bottom, the body 4 of the rail 3 preferably ends with a widened base 13 through which the longitudinal support edges 14 on each side permitting its fixation. In addition to its guiding function, the rail 3 can be used, for example, as a support material for one or a plurality of conductor paths 15 for feeding or zero-volt return. For example, the number of these conductor tracks made of steel is preferably two and at the same time arranged on each side 16 of the guide rail 3. As shown in FIG. 5, these conductor tracks 15 are preferably symmetrical and substantially vertical at the same time.

During operation, two current-carrying components 17, an example of which is shown in FIG. 6, move on both sides of the guide rail 3, and these current-carrying flanges 18 press against each other and slide along the conductor track 15.

An embodiment of a traffic trajectory 1 capable of crossing according to the present invention is shown in the cross section of FIG.

In this embodiment, among other things, the supply of the on-board electrical circuit from the floor, i.e. the current supply device 19 arranged on the floor, and the two complementary devices cooperating to enable the energization device 20 to move with it. The vehicle power supply device to be formed is illustrated.

The current supply device 19 is housed in a groove portion 21 having a substantially rectangular cross section with an upper surface opened in the excavation groove. This preferably consists mainly of a central rail 3 and at least one and preferably two linear conductors 22 each connected to a supply voltage. These conductors 22 are parallel and adjacent to the guide rail 3 at the same time. One of these surfaces is used as a conductor path for a slip element or a voltage collecting flange. For this reason, this is called the transverse conductor path 23. In the case of two conductors, there are two lateral conductor paths 23.

In this example, the return of zero potential is therefore made along the rail 3 on which the two conductor paths 15 of preferably symmetric zero volt return are mounted. The rail 3 is also used as a guide rail for a vehicle guide device or a power supply device.

The rail 3 is fixed to the bottom of the groove portion 21 on the sleepers 24 arranged at equal intervals. The horizontal ends of these sleepers 24 are fixed by a clamp that divides the boundary of the current supply device 19 in the horizontal direction at the lower end of the lateral cross section 25. The straight conductors 22 forming the transverse conductor paths 23 are supported by and suspended by a series of suspension hardware 26 fixed at intervals on the transverse cross section 25. A protective cross section 27 is secured to the upper end surface of each flank cross section 25 so that any access to the straight conductor 22 under unacceptable voltage is prohibited.

The collection of electrical energy necessary for the function of the vehicle utilization circuit is performed by the energization device 20 mounted on the vehicle including the two energization moving components 17 that travel in the grooves 21 on both sides of the rail 3.

Each of these energized components 17 has an output flange 28 that is in sliding contact with the lateral path 23 of the corresponding power supply 22 at its center position, and a corresponding zero bolt supported by the rail 3 on its lateral side. A zero bolt flange 29 arranged to come into sliding contact with the conductor return path 15 is included and directed towards the rail 3.

Of course, these flanges are preferably mounted in a resiliently restored state with their corresponding conductors to ensure satisfactory electrical contact in all situations.

The two energization components 17 are mechanically coupled at the same time supported by a support overhead device 30 which additionally secures an electrical connection between these energization components 17 and the vehicle user circuit. The support overhead wire device 30 is preferably mounted on a guide armrest of the vehicle from the viewpoint of dynamic stability.

According to the present invention, the intersection of two tracks is produced in a good manner.

In the plane of the intersection 2, the rail 3 is preferably fixed to a substantially flat bottom plate 31 via a clamping part 32, for example called a crammage. In the example shown, the guide rail 3 is preferably approximately in the center of each running track 1.

The two guide rails 3 are interrupted locally in a region 33 corresponding to these intersections. Similarly, in some cases, the necessary linear feeder 22 is also interrupted at the intersection region 33.

In the middle of this region 33, ie in the geometry of the intersection, away from the end 35 of the guide rail 3 to be interrupted and at the same time away from the end 36 of the interrupted conductor 22 as required. The core part 34 is attached.

This core part 34 is preferably a support-mediating part formed, for example, from a diamond-shaped cross-section 37, which is extended at the top by a wider and generally diamond-shaped head 38.

The head part 38 of the core part 34 presents a guide roller travel path 39 corresponding to the extension part of one travel path 11 of the guide rails 3 on both sides of the core part 34 and corresponding to the extension. The

Thus, with respect to the embodiment shown, the head 38 of the core part 34 is extended as a head 9 of the guide rail 3 by an oppositely inclined runway 39, which is gathered upward and at the same time by the board surface 41. A lower flank 40 is included that extends at the same time as the slant is joined at the upper portion.

Due to the presence of the core component 34, it is possible to ensure the continuity of guidance by the guidance roller. In order for this purpose to be achieved, the section rails 3 before and after the intersection 2 must be continued as close as possible to this core part 34.

The main body 37 of the core component 34 must be installed sufficiently tightly on the base so as not to interfere with the passage of the current-carrying flange 18.

The core part 34 includes in its lower part, for example, a substantially flat and horizontal and preferably rhombus shaped pedestal 42 which is fixed to the bottom plate 31 via this. This pedestal 42 must be large enough to ensure good stability of the core component 34.

In order for the current carrying device to be able to pass without the risk of obstruction, breakage or contact, sufficient free space must be left in the intersection area of the lower part of the device.

In this respect as well as indispensable features of the invention, the guide rail 3 has its lower part hollowed out or discarded over these full length parts 43 located in the vicinity of the intersection area 33 from or before the intersection area. It is what was done.

Sufficient free space for the passage of the energized components 17 is thus left in the intersection region 33 which is very close to each other while the travel path 11 necessary for guidance is maintained for a long time by the guide rail 3.

The remaining upper part 44 of the rail 3 in the cantilever state must therefore be supported by stress only with the guide arm. The upper part of the rail 3 in the cantilever 44 state can be stiffened by the lower conductor core so that the risk of breakage is avoided. This is for example a problem with the stiffening rod 45, which can be placed in a longitudinal cavity which is preferably made of steel and for example a hollow tube is installed in the upper part of the rail.

Conveniently, in the variant shown, the stiffening bar 45 can be accommodated in the inner conduit means 8 of the guide rail 3 in the region of the upper part of this cantilever 44 state.

The stiffening rod 45 is inserted, for example, into the receiving groove when the rail is installed or manufactured. Further, in the case of a guide rail made of a plastic material, it can be considered that the rail is matched with the shaft rod 44. The length of the portion 43 to be hollowed out or discarded is preferably shorter than half the length of the vehicle track that supports the guide arm.

When this length is exhibited, the conductor track 15 is interrupted over the entire length 43 of the guide rail 3 where the adjacent portion of the corresponding side 16 is hollowed out or discarded. In order for the mechanical pulling force to be transmitted gradually as soon as the energizing flange 18 is gradually released, the conductor track 15 of the guide rail 3 is a region 43 that is hollowed out or discarded in the upper part of the cantilever. At the beginning and at the end, an interruption is initiated through a transition zone 46 where the engagement / release is carried out, preferably in the form of a ramp 47, for the energizing flange 18 rubbing on the ramp upstream and downstream of the intersection 33. Is preferred.

This ramp 47 may take the form of, for example, one or two continuously-graded slopes, a rounded shape or any other suitable gradual change.

The same applies to the lateral conductor path 23 of the conductor 22 which is interrupted, for example, at the beginning of the region in the cantilever 43 state or in a region fitted slightly forward in the region.

At least one of these transverse conductor tracks 23 is in the state of a mesh / release ramp 49 that allows a corresponding progressive engagement or disengagement and smooth energization flange 28 moving over its interrupted end face. A transition zone 48 is presented. This transition zone 48 can be produced in the form of a ramp with one or two consecutive slopes as described above.

The temporary disengagement of the contact slip of the current-carrying flange 18 on the interrupted one or more conductor tracks 15 and / or 23 is for example arranged at the opposite end of another electrical current-carrying device, for example a train or vehicle. It can be temporarily relayed by another vehicle energizer. Further, it may be compensated by a shift in power supply of the vehicle by the mounted battery device. It can also be considered that this temporary power disconnection is not compensated for the vehicle that continues over the take-out section for crossing a short intersection.

Furthermore, as shown in FIG. 2, the surface of the upper portion of the guide rail 3 is matched with the surface of the upper portion of the guide rail 3 by the support member 50 that is fixed to the bottom plate 31 by, for example, mechanical welding. It is possible to fix the protective plate 51 which is preferably located almost on the floor surface.

Although these protective plates 51 prohibit access to the conductor path 15 and other dangerous elements under high pressure, the free running path 11 of the head 9 of the guide rail 3 remains. These protective plates 51 can withstand the vehicle weight acting on the wheels traversing them.

As will be apparent, the invention is not limited to the preferred embodiments described above and shown in the various drawings, and many modifications may be made by an expert without departing from the scope and scope of the invention. Other variations can be created at the same time that examples are provided.
