Description
- The invention relates to transport by ground cable.
- Ground cable installations, such as funicular railways, are currently used for transporting people in urban environments, or for journeys over short distances.
- French Patent application FR2943025 can be cited which discloses an installation of transport, comprising two hauling cables to which a carrier is successively coupled in reversible manner, by two mechanisms, to haul it to-and-fro along a single running track connecting two end stations. Running of the hauling cables is performed by two drive units. But this installation is complex as it is necessary to maintain operation of two drive units and to perform maintenance of two hauling cables.
- Furthermore, French Patent application FR2942194 discloses an installation of transport, comprising a hauling cable to which a carrier is successively coupled in reversible manner, by two coupling mechanisms, to haul it in to-and-fro manner along a single running track connecting two end stations. The installation further comprises intermediate stations arranged along the running track between the end stations for loading and unloading people. But this installation is also complex as the carrier has to be uncoupled in each intermediate station and end station, which results in fatigue of the coupling mechanisms and an increase of the frequency of maintenance operations.
- French Patent application FR2133102 can also be cited which discloses an installation of transport, comprising a ground cable to haul several carriers along two guide tracks arranged symmetrically with respect to a vertical plane, and several carriers equipped with guide means situated on a single lateral side of the carriers so as to cooperate only with one of the guide tracks. The carriers are further provided with detachable grips to attach the carriers to the cable in removable manner so as to slow the carriers down in the stations to facilitate loading and unloading of people, and so as to be able to return the carriers to attach them to the return strand of the cable. But this installation is complex as it requires the use of deceleration, acceleration and bypass circuits in each of the stations to move the carriers which are detached from the cable.
- European Patent application EP0347324 can be cited which discloses an installation of transport, comprising a ground cable to haul in to-and-fro manner two carriers along a track provided with an asymmetric sidestep to enable the carriers to pass one another in the opposite direction and halfway from the end stations of the installation. The carriers can be equipped with detachable grips to attach the carriers to the cable in removable manner to modify the position of a carrier when the length of the cable is modified or when the position of a station is modified. But this installation is not suitable when an intermediate station is to be placed on the track, without having to compulsorily place it halfway from the end stations.
- One object of the invention consists in palliating these shortcomings, and more particularly in providing an installation and a method of transport by ground cable that is simple and that enables people to be loaded and unloaded in three stations situated at distinct positions from one another.
- According to one feature of the invention, a method of transport by ground cable of two carriers is proposed, each carrier being provided with an attachment means configured to attach the carrier in removable manner to the ground cable, comprising a hauling step by the ground cable of the two carriers in the direction of two end stations respectively situated at the ends of the ground cable.
- The method comprises a crossing step of the carriers between a first end station and an intermediate station situated between the two end stations, a reversal step of the direction of rotation of the ground cable when a carrier reaches the second end station, and a stopping step of a carrier in the intermediate station.
- A simplified method is thus provided for transporting people in three distinct stations by means of only two carriers. Advantageously, such a method enables the intermediate station to be placed at any distance from the end stations, thereby providing freedom as regards implementation of the method of transport. Such a method further enables maintenance operations to be limited, in particular due to the use of a single ground cable.
- The method can comprise a detachment step of each carrier when the carriers reach the first end station.
- In this case, means can be positioned to only detach the carriers in one of the end stations, which simplifies the method of transport. The number of detachments of a carrier from the ground cable is thus limited, which enables the maintenance operations on the attachment means of the carriers to be reduced.
- During a stopping step of a carrier, the carrier can be secured to the ground cable.
- It is therefore not necessary to detach the carriers from the ground cable when they are situated in the intermediate station, which limits maintenance operations on the attachment means even further.
- According to another feature of the invention, an installation of transport by ground cable is proposed comprising two carriers, each provided with an attachment means configured to attach the carrier in removable manner to the ground cable, and two end stations respectively situated at the ends of the ground cable.
- The installation comprises an intermediate station situated between the two end stations, a sidestep situated between a first end station and the intermediate station and configured to enable the carriers to cross paths, and reversible drive means of the ground cable configured to reverse a direction of rotation of the ground cable when a carrier reaches the second end station.
- The installation can comprise a single detachment device of the carriers from the ground cable situated inside the first end station.
- A carrier can be situated in the intermediate station and attached to the ground cable.
- Other advantages and features will become more clearly apparent from the following description of particular embodiments and implementation modes of the invention given for non-restrictive example purposes only and represented in the appended drawings, in which:
-
FIGS. 1 to 6 schematically illustrate the main steps of an implementation mode of the invention; and -
FIG. 7 schematically illustrates a cross-sectional view of an embodiment of a transport installation according to the invention. - In
FIGS. 1 to 6 , an embodiment of atransport installation 1 byground cable 2 has been represented. What is meant byground cable 2 is a hauling cable situated at ground level, unlike an overhead cable used for aerial cable carriers, such as gondola lifts or chair lifts. Atransport installation 1 byground cable 2 is also called a funicular railway. The installation comprises two carriers S, T, twoend stations ground cable 2, hereafter referred to ascable 2. In other words, theend stations cable 2. Each carrier S, T comprises an attachment means 6 configured to attach the carrier S, T in removable manner to thecable 2. The attachment means 6 can be a grip, called detachable grip, having a closed position in which the grip tights thecable 2 so as to be able to haul the carrier S, T, and an open position in which the carrier S, T can be detached from thecable 2. Theend stations wheel first end station 4 comprises adrive wheel 7 coupled to a motor and configured to drive thecable 2. Thesecond end station 3 for its part comprises areturn wheel 8 enabling thecable 2 to be tensioned. Thecable 2 is thus stretched taut between thedrive wheel 7 and thereturn wheel 8, and delineates arunning track end stations ground cable 2 is continuous and describes a closed loop. When thedrive wheel 7 is made to rotate in a first counterclockwise direction of rotation X, it drives thecable 2 in the first counterclockwise direction X (illustrated inFIGS. 1 to 3 ). In other words, afirst strand 2 a of thecable 2 is driven in translation in the direction of thesecond end station 3 and, inversely, asecond strand 2 b of thecable 2 is driven in translation in the direction of thefirst end station 4. The drive means 5, such as a motor, are further configured to reverse the direction of rotation of thecable 2 to drive it in a second clockwise direction of rotation Y (illustrated inFIGS. 4 to 6 ), making thedrive wheel 7 rotate in a second direction of rotation Y opposite to the first direction of rotation X. - The
installation 1 further comprises anintermediate station 10 situated between the twoend stations intermediate station 10 enables unloading and loading of people in the carriers S, T. In general manner, theintermediate station 10 comprises platforms to receive the people leaving the carriers S, T, and to allow people to wait for a carrier S, T which they want to board. Theintermediate station 10 is situated at a first distance from thefirst end station 4 and at a second distance from thesecond end station 3. For example, the first distance can be greater than the second distance. Theintermediate station 10 can be situated halfway 15 from theend stations intermediate station 10 is preferably situated at one third of the length of therunning track running track first section 17 connecting thefirst end station 4 to theintermediate station 10 and asecond section 18 connecting thesecond end station 3 to theintermediate station 10. - The
installation 1 preferably comprises asidestep 11 configured to enable the carriers S, T to cross paths. Thesidestep 11 can be situated in theintermediate station 10 or be situated between theintermediate station 10 and one of theend stations sidestep 11 can be situated at thelevel 14 of thefirst section 17 of the running track. Preferably, thesidestep 11 is situated halfway 14 from theintermediate station 10 and from thefirst end station 4. According to one embodiment, thesidestep 11 comprises twobranches strands cable 2 respectively run. Thus, when the carriers S, T are hauled by thecable 2, they run in the opposite direction on thefirst section 17, and when thedrive wheel 7 is made to move in rotation in the first direction of rotation X, a first carrier S runs along thefirst branch 12 and the second carrier T runs along thesecond branch 13 and can cross paths with the first carrier S. - The
installation 1 can further comprise adetachment device 16 of the carriers S, T from thecable 2. Such adetachment device 16 can be controlled by control means 16 a configured to command detachment of a carrier S, T. - An embodiment of the
installation 1 has further been represented inFIG. 7 in which a carrier T comprises acar 30 mounted on achassis 31, and running means 32, 33 configured to enable translational movement of the carrier T along the runningtrack support structure support structure rails track shafts chassis 31 so that the carrier T can run on therails branches branches sidestep 11. The carriers S, T can be identical to simplify the installation oftransport 1, i.e. the attachment means 6 can be situated in the same position on the two carriers S, T. - The installation of
transport 1 provides the possibility of transporting people in threedifferent stations installation 1 is furthermore as simple as possible and comprises asingle cable 2, two carriers S, T and threestations installation 1 enables maintenance operations to be limited. - In
FIGS. 1 to 6 , the main steps of a method of transport bycable 2 of two carriers S, T have also been represented. The method can be implemented by the installation oftransport 1 described in the foregoing.FIG. 1 illustrates an initial step of the method. In this initial step, a first carrier S is situated in theintermediate station 10 and the second carrier T is situated in thefirst end station 4. The two carriers S, T are attached to thecable 2, and in this case the attachment means 6 are represented by black circles. Then the method comprises a hauling step during which thecable 2 hauls the two carriers S, T in thedirection respective end stations opposite directions first station 4 and the second carrier T towards theintermediate station 10. In this case thedrive wheel 7 rotates in the first counterclockwise direction X. The two carriers S, T cross paths at thelevel 14 of thefirst section 17, and they respectively reach thefirst end station 4 and theintermediate station 10, as illustrated inFIG. 2 . The method further comprises a stopping step in which the second carrier T is stopped in theintermediate station 10. The stopping step enables people to alight and embark. Preferably, during the stopping step, running of thecable 2 is stopped when a carrier S, T reaches anew station cable 2, and it is not necessary to detach the carrier T from thecable 2. The opening and closing actions to be performed on the attachment means 6 are thus reduced to limit their wear. - Then, as illustrated in
FIG. 3 , the first carrier S is detached from thecable 2 so as to enable the second carrier T to be hauled towards thesecond end station 3. The attachment means 6 of a carrier S, T have been represented by a white circle when the carrier S, T is detached from thecable 2. The second carrier T is therefore hauled in thedirection 22 and reaches thesecond station 3 where it remains attached to thecable 2. - Then, as illustrated in
FIG. 4 , a reversal step is performed during which the direction of rotation of thecable 2 is reversed. In other words, the direction of rotation of the cable is reversed when a carrier S, T reaches thesecond end station 3. In this case, thedrive wheel 7 rotates in the second clockwise direction of rotation Y and the second carrier T is hauled in translation in the direction of theintermediate station 10, which it reaches. When the second carrier T reaches theintermediate station 10, the carrier T is stopped and remains attached to thecable 2. Then the first carrier S is again attached to thecable 2, and driving of thecable 2 is resumed in the second direction of rotation Y. The first carrier S is then hauled in thedirection 25 of theintermediate station 10 and the second carrier T is hauled in thedirection 24 of thefirst end station 4. - As illustrated in
FIG. 5 , the carriers S, T respectively reach theintermediate station 10 and thefirst end station 4. Furthermore, the second carrier S is stopped in theintermediate station 10. - Then, as illustrated in
FIG. 6 , the second carrier T is detached from thecable 2, detachment being performed in thefirst station 4, in particular by means of thedetachment device 16. Preferably, thedetachment device 16 is located only in thefirst end station 4. In other words, the detachment step is performed for both of the carriers S, T, when the carriers S, T reach thefirst end station 4. Such a method of transport enables a carrier S, T to be detached once only during a to-and-fro path of the carrier S, T. What is meant by a to-and-fro path of the carrier S or T is the path that the carrier S or T covers when leaving a firstinitial station installation 1, and returning to the firstinitial station cable 2 is then resumed in the second direction of rotation Y to haul the first carrier S, in thedirection 26, to thesecond end station 3, which it reaches. - Furthermore, as soon as the first carrier S reaches the
second end station 3, the direction of rotation of thedrive wheel 7, and therefore of thecable 2, is reversed. This reversal enables the first carrier S to be driven back to theintermediate station 10, and theinstallation 1 is back in its initial configuration illustrated inFIG. 1 . - The invention which has been described in the foregoing is particularly suitable to reduce maintenance operations of an installation of transport by ground cable. The invention enables transport of people to three distinct stations to be performed using means that are simple to achieve and to implement.
