Ground-based power supply and associated reinforcing method

1. A ground-based system for powering a vehicle, wherein the system comprises:

a track, which defines a trajectory of the system, wherein the track is designed to be in contact with a pickup shoe of the vehicle during movement of the vehicle along the trajectory, wherein the track comprises:

at least one track segment terminating at a segment end in a forward direction of the trajectory, and

at least one hood, which is arranged as an extension of the track segment along the trajectory in the forward direction beyond the segment end;

at least one stringer, which supports the track segment and which extends along the trajectory ending with a cut end in the forward direction;

wherein the system further comprises at least one reinforcing piece which is applied to the cut end in order to extend the stringer in the forward direction, wherein the reinforcing piece is essentially made of plastic and supports the hood,

wherein the system comprises a support on which the stringer and the reinforcing piece rest,

wherein the reinforcing piece comprises a base, through which the reinforcing piece rests on the support, wherein the base comprises at least one sealing notch that extends parallel to the trajectory and opens radially with respect to the trajectory, and

wherein a sealing material is introduced into the sealing notch to ensure the fixing of the reinforcing piece to the support.

2. The system according to claim 1 , wherein the plastic material of the reinforcing piece is polyamide 6.

3. The system according to claim 1 , wherein:

the stringer comprises a stringer groove, which extends along the trajectory, to the cut end in the forward direction, while the track segment is housed in the stringer groove; and

the reinforcing piece comprises a reinforcing groove, which extends the stringer groove in the forward direction, while the hood is arranged at least partially in the reinforcing groove and is supported by the reinforcing piece.

4. The system according to claim 3 , wherein:

the stringer comprises two stringer edges bordering the stringer groove; and

the reinforcing piece comprises two reinforcing edges bordering the reinforcing groove by extending the grooves in the forward direction, wherein the hood is arranged at least partially in the reinforcing groove without covering the reinforcing edges.

5. The system according to claim 4 , wherein:

the stringer comprises two antenna holes, which respectively extend in the stringer along the stringer edges, and open at the cut end;

the reinforcing piece comprises two reinforcing wings, which protrude opposite one another, wherein each of the two reinforcing wings support one of the reinforcing edges, wherein the reinforcing piece comprises two antenna ducts, wherein each of the two antenna ducts passes through one of the two reinforcing wings, wherein the reinforcing piece is so arranged that each of the two antenna ducts respectively extends one of the two antenna holes in the forward direction; and

the system comprises at least one antenna cable, which passes through one of the two antenna holes and the two antenna ducts.

6. The system according to claim 1 , wherein:

the hood is fixed on the reinforcing piece using at least one mechanical fixing device, wherein the mechanical device comprises a primary element, and a secondary element to which the primary element is attached;

the reinforcing piece comprises an access hole, which opens in the forward direction on an access face of the reinforcing piece; and

the primary element of the mechanical device passes through the hood and the reinforcing piece in order to extend into the access hole, in which is housed the secondary element.

7. The system according to claim 1 , wherein:

the stringer comprises at least one wiring hole, which extends along the trajectory and which opens at the cut end;

the reinforcing piece comprises at least one wiring duct, wherein the reinforcing piece is arranged in such a way that the wiring duct extends the wiring duct in the forward direction; and

the system comprises at least one power cable of the track, which passes through the wiring hole and the wiring duct.

8. A method for reinforcing a ground-based system for powering a vehicle, wherein the system comprises:

a track, which defines a trajectory of the system, wherein the track is designed to be in contact with a pickup shoe of the vehicle during movement of the vehicle along the trajectory, wherein the track comprises:

at least one track segment terminating at a segment end in a forward direction of the trajectory, and

at least one hood, which is arranged as an extension of the track segment along the trajectory in the forward direction beyond the segment end;

at least one stringer which supports the track segment and which extends along the trajectory terminating in a stringer end in the forward direction, wherein the stringer comprises a portion to be replaced, extending from the stringer end in a direction opposite to the forward direction, wherein the hood is supported by the portion to be replaced;

wherein the method comprises:

separating the portion to be replaced from the stringer, so that the stringer terminates with a cut end in the forward direction;

adding at least one reinforcing piece of the cut end, by applying the reinforcing piece against, or opposite, the cut end in order to extend the stringer in the forward direction, wherein the reinforcing piece is made essentially of plastic material; and

mounting the hood on the reinforcing piece, so that the hood is supported by the reinforcing piece,

wherein the system comprises a support on which the stringer and the reinforcing piece rest,

wherein the reinforcing piece comprises a base, through which the reinforcing piece rests on the support, wherein the base comprises at least one sealing notch that extends parallel to the trajectory and opens radially with respect to the trajectory,

the method comprising introducing a sealing material into the sealing notch to ensure the fixing of the reinforcing piece to the support.

9. The method according to claim 8 , wherein:

the stringer has at least one empty hole, which extends along the trajectory and which opens at the cut end; and

the method comprises a step of introducing at least one reinforcing bar of plastic material into the empty hole in an adjusted manner in order to support the empty hole.

10. The method according to claim 9 , wherein the plastic material of the reinforcing bar is the same plastic as the of the reinforcing piece.

11. The system according to claim 1 , wherein the stringer is made of composite material of pultruded fiberglass.
