Description

TECHNICAL FIELD [0001] The present invention relates to a mechanical elevating vehicle, and a facility including the elevating vehicle,

The present invention relates to a mechanical lift vehicle and a mechanical lift facility including such a vehicle.

Generally, a mechanical lift facility allows a passenger, skier, or pedestrian to ascend or descend the slope. The mechanical lift facility generally comprises two end stations, a station located at the bottom of the slope and a station located at the top of the slope. These end stations are connected by public transport and carrying cables that can form a closed loop. It is known to drive the cable through the pulley and to support the cable using a pylon. A vehicle suspended from a cable allows the passenger to be transported from one end station to another end station.

When the cable forms a closed loop, each end station may include an area for loading and unloading passengers. Thus, the mechanical lift facility enables simultaneous transport of passengers climbing or descending slopes.

The mechanical lift vehicle may be detachable or non-detachable. If detachable, the vehicle may be disconnected from the cable that is suspended to be transported to the secondary itinerary when it arrives at the boarding or unloading area. In the secondary journey, the vehicle speed is reduced to facilitate passengers' boarding or getting off, providing more comfort and stability. If the vehicle is not detachable, the vehicle remains permanently on the suspended cable. In this case, the absence of the separation system imparts a simpler structure to the mechanical lift facility.

Many types of mechanical lifts are distinguished as follows: a drag lift (a ski being transported by a tackle while the user is in contact with the ground), a public transport vehicle using a cable car, in particular a gondola and a chairlift (The user is transported without touching the ground).

The chair lift also includes a guard rail that is traditionally movable between a high position and a low position where the guard rail opens the space for a passenger to board or get off and at a low position the guard rail drops So as to form an obstacle.

In order to ensure a high level of safety when the chair lift vehicle moves between the end stations, it is necessary to lock the guard rail in a low position when the vehicle is moving between the two end stations, and when the vehicle is in the end station for boarding or unloading of passengers Unlocking the guard rail is disclosed in the patent document WO 2012/080603. As described in patent document WO 2012/080603, the guardrail locking means may comprise an electromagnet cooperating with a magnetizable member, wherein the electromagnet is electrically connected to an electrical conductor mounted on the vehicle. The guard rail may be supplied or disconnected to or from the electromagnet through a conductor mounted on the vehicle in order to lock or unlock the guard rail, thereby exerting or not exerting a force on the magnetizable member.

This solution works in particular as a continuous supply as described in patent document FR 2 937 938, which comprises a fixed electrical conductor with a plurality of flexible conductive contact wires forming a conductive brush, and a movable conductor, And a movable conductor mounted on the vehicle for causing an electrical contact to be made when contacted.

However, such a continuous supply device is difficult to retrofit an old facility. In fact, it is impossible to add mechanical stress to the structural elements of the mechanical lift seat due to the initial dimensions of such a facility.

Patent document WO 2012/095606 overcomes this inconvenience by suggesting a conductive brush of a movable support structure to carry out continuous supply of the vehicle. Such a moveable structure includes a movable dangling arm adapted to the oscillating motion of the suspension to maintain electrical contact without mechanically stressing the suspension of the mechanical lift seat.

However, the weight of this movable structure sometimes requires the addition of support pylons. In some cases, the addition of such support pylons may be complicated and / or costly to implement.

The present invention is based on the finding that the present invention has the advantage that it has a relatively small mass to limit the complexity and cost of execution without imposing mechanical stress on the suspension of the vehicle and to provide reliable control of the predetermined technical function, The object of the present invention is to overcome such inconvenience by providing a vehicle and a mechanical lift facility.

To this end, it is an object of the present invention to provide a mechanical lift vehicle, which comprises a suspension and a controller, the suspension having a top portion, the suspension portion extending transversely from the top portion, Wherein the mechanical lift vehicle is adapted to be suspended from a public transport and carrying cable, the controller being adapted to control a predetermined technical function of the mechanical lift vehicle, the mechanical lift vehicle further comprising an offset arm, a buttress member, Wherein the offset arm extends from a side opposite to one side of the upper end extending from the suspension, in a transverse plane substantially perpendicular to the longitudinal axis of the mechanical lift vehicle, the offset arm being disposed at a height of the upper end of the suspension Supporting the proximal end and the controller Wherein said offset arm is adapted to bear said buttress member and said connecting means connects the proximal end of said offset arm to said suspension and said connecting means comprises a transverse section substantially perpendicular to the longitudinal axis of said mechanical lift vehicle, Wherein the offset arm is movable relative to the suspension between a pre-engagement position and a mating position, and wherein the offset arm supporting the buttress in the pre-mating position comprises a mechanical lift arrangement And the offset arm is adapted to slide along the guide ramp at a distance from the buttress member so that the controller can perform the predetermined technical function.

Therefore, the mechanical lift vehicle according to the present invention is capable of being independent of suspension vibrations caused by eccentric loads or strong side winds, without any mechanical stress of the suspension or other types of mechanical stresses, heavy weight vehicles or equipment, Presenting the possibility of forming a reliable control, the present invention can be used not only for modern equipment with detachable or non-detachable vehicles, but also for old equipment.

It should be noted that the arm is located at the height of the upper end of the suspension, i.e., where the vibration of the suspension is at its weakest, so that this vibration slightly changes the position of the offset arm relative to the guide ramp. This contributes to contact reliability for any slope of the suspension.

Furthermore, lateral offsetting of the controller through the offset arm by moving in a direction away from the vertical axis of the mechanical lift vehicle allows control of predetermined technical functions to be performed away from the suspension. Therefore, this is unlikely to come into contact with the guide lamp disposed on the offset arm path even when the suspension vibrates due to strong cross wind or eccentric load. The result is complete freedom of suspension movement, which can be guided or mechanically stressed during displacement of the mechanical lift vehicle.

Finally, the extension of the opposite side offset arm on the side where the suspension extends extends to prevent the aerial carrying and transport cables from forming possible obstacles to displacement of the offset arm, for better contact reliability.

According to one embodiment, the controller is formed of two electrical conductors that are substantially cylindrical and aligned along the arm, each electrical conductor adapted to cooperate with the heat of the electrically conductive brush of the mechanical lift facility, Are spaced apart from each other by a predetermined distance so that all of the two electrical conductors are prevented from coming into contact with the same heat of the electrically conductive brush.

This feature has the advantage of enabling reliable electrical contact between the mechanical lift facility and the mechanical lift vehicle.

Advantageously, the offset arm and the butt member are disposed relative to each other such that the offset arm is returned to the pre-engagement position relative to the butt member only by gravity effect.

That is, the mechanical lift vehicle does not have a retrieving means for returning the offset arm to the pre-engagement position in an active manner.

This feature has the advantage of limiting the number of parts. The result is a limited mass and a need for reduced maintenance.

According to one embodiment, the connecting means comprise a pivotal connection P1 having an axis substantially parallel to the longitudinal axis of the mechanical lift vehicle, such that the offset arm rotates about the suspension in a cross-section substantially perpendicular to the longitudinal axis of the mechanical lift vehicle .

The pivot connection has the advantage that it is a simple and reliable solution which enables displacement of the offset arm.

According to one possibility, the connecting means comprises a flexible longitudinal element, the distal end of the longitudinal element being fastened to the proximal end of the offset arm, the proximal end of the longitudinal element being stationary with respect to the suspension, The offset arm is displaceable in a transverse section substantially perpendicular to the longitudinal axis of the mechanical lift vehicle.

This feature has the advantage of eliminating the need for a mechanical connection as a joint between the offset arm and the suspension, and such connection requires little maintenance.

Advantageously, the connecting means comprises a connecting arm fixed to the suspension and an inclined portion extending to the distal end where the butting member is fixed, the connecting arm having the distal end connected to the proximal end of the offset arm, And an intermediate portion of the offset arm formed between the portions is supported by the butting member 16 in the pre-engagement position.

Using a connecting arm to directly connect the offset arm to the suspension has the advantage of applying this solution to older equipment and mechanical lift vehicles.

The present invention also relates to a mechanical lift facility comprising two end stations connected by air transport and carrying cables, a mechanical lift vehicle having the features described above, and a guide lamp, The offset arm is displaced by sliding the offset arm along the guide ram when the mechanical lift vehicle passes over the guide ramp so that the offset arm is displaced as a result of the predetermined arm The technical function is performed.

Advantageously, the guide ramp is disposed in or adjacent to the boarding area of one of the end stations or immediately adjacent to or in the getting-off area.

According to one possibility, the mechanical lift facility is an inseparable type of installation.

However, the mechanical lift facility may be of a separable type.

According to one possibility, the mechanical lift facility comprises a mechanical lift vehicle with the features described above, comprising two rows of conductive brushes substantially parallel to one another and substantially parallel to the transport and carrying cables, two of the conductive brushes All of the heat is placed above and / or below the guide ramp so that it comes into contact with one of the electrical conductors as the offset arm slides along the guide ramp.

Other features and advantages of the present invention will become apparent from the following description of an embodiment of the invention given as a non-limiting example with reference to the accompanying drawings.

1 is a side view of a mechanical lift vehicle according to an embodiment of the present invention.
2 is a front view of a mechanical lift vehicle according to an embodiment of the present invention.
3 and 4 are detailed front views of a mechanical lift vehicle according to an embodiment of the present invention.
5 is a schematic view of a mechanical lift arrangement including a mechanical lift vehicle in accordance with an embodiment of the present invention.

Figures 1 and 2 illustrate a mechanical lift vehicle 1, in particular a public transport vehicle, in this case a mechanical lift seat, according to an embodiment of the present invention. Such a mechanical lift seat may include a guard rail 2 movable between a high position and a low position wherein the guard rail 2 opens the space for the passenger to board or get off, (2) forms an obstacle so that the passenger does not fall. The high position and the low position are shown in FIG. 1 at the same time.

This description is made explicitly for Cartesian reference coordinates as shown in Figures 1 and 2 for the mechanical lift vehicle 1, with the X-axis being oriented in the longitudinal direction of the mechanical lift vehicle 1, the Y- Is oriented in the lateral direction of the vehicle 1, and the Z-axis is oriented in the vertical direction of the mechanical lift vehicle 1. [ Accordingly, the displacement, orientation, direction, and plane of the longitudinal, transverse, or vertical, front, rear, top, and bottom ends are defined for these reference coordinates.

As shown in Figures 1 and 2, the mechanical lift seat includes a suspension 4. Suspension 4 has an upper end 6, as can be seen in particular in FIGS. 3 and 4, extending from the upper end in a plane transversely, i.e. substantially perpendicular to the X-axis. The hanging section 8 is adapted to hang the mechanical lift sheet on the public transport and conveyance cable 10 as shown in Figs. 1, 3 and 4.

The upper end 6 of the suspension 4 corresponds to the upper end of the suspension 4 as opposed to the lower end or the lower end of the suspension 4 and is fixed to the mechanical lift vehicle frame as shown in Fig.

The mechanical lift seat also includes a coupling device connecting the controller 12, the offset arm 14, the buttress member 16, and the offset arm 14 to the suspension 4, .

The controller 12 is adapted to control a predetermined technical function. According to the embodiment shown in Figures 1-4, the controller 12 corresponds to an electrical sensor formed of two electrical conductors 18, which are substantially cylindrical and aligned along the offset arm 14, To cooperate with the heat of the electrically conductive brush 20 of the facility 100.

As shown in Figures 3 and 4, the electrical conductors 18 are spaced apart from each other by a predetermined distance so that both electrical conductors 18 are prevented from contacting the same heat of the electrically conductive brush 20.

The electrically conductive brush 20 may be formed of a plurality of flexible conductive wires and the free ends of the conductive wires may be adapted to abut one of the electrical conductors 18 to provide an electrical connection between the mechanical lift facility 100 and the mechanical lift seat. Thereby forming an electrical connection.

This electrical connection allows to control the performance of a predetermined technical function corresponding to the magnetic unlocking of the guard rail 12, for example as described in patent document WO 2012/080603. The electrical conductor 18 thus belongs to an electrical circuit which is intended to be supplied through the electrically conductive brush 20, for example to control the resetting of the locking and unlocking of the guard rail 2 of the mechanical lift seat.

The offset arm 14 extends in a cross-section substantially perpendicular to the longitudinal axis Y of the mechanical lift seat. The offset arm 14 further extends from the opposite side of one side of the top portion 6 from which the suspension portion 8 extends.

3 and 4, the offset arm 14 has a proximal end disposed at the height of the upper end 6 of the suspension 4 and a distal end supporting the controller 12. As shown in Fig.

It should be noted that the offset arm 14 can only be used for the offset of the controller 12 to allow displacement of the controller 12 upon contact with the guide ramp 104. [

The buttress member 16 is adapted to be received as a bearing of the offset arm 14. The offset arm 14 and the buttress member 16 can be disposed relative to each other such that the offset arm 14 is withdrawn to the pre-engagement position relative to the buttress member 16 only by the effect of gravity. The butting member 16 is disposed below the offset arm, for example, to support the offset arm 14.

The connecting device is capable of directly or indirectly connecting the proximal end of the offset arm 14 to the suspension 4 so that the displacement of the offset arm 14 in a transverse section substantially perpendicular to the longitudinal axis Y of the mechanical lift seat, .

Thus, the offset arm 14 is movable relative to the suspension 4 between the pre-engaged position (not shown) and the engaged position (shown in FIGS. 2 to 4) The offset arm 14 is adapted to come into contact with the guide ramp 104 of the mechanical lift facility 100 and the offset arm 14 at a distance from the buttress member 16 along the guide ramp 104 So that the controller 12 can perform predetermined technical functions. 2 to 4, in the mating position, the electrical conductor 18 abuts against the heat of the electrically conductive brush 20. Thus, an electrical connection is made between the mechanical lift facility 100 and the mechanical lift seat at the mating position.

In the connecting position, the offset arm 14 can be substantially horizontal, and in the pre-engagement position, the offset arm 14 has an angle of substantially less than 45 degrees with respect to horizontal, in particular less than 30 degrees, The inclination can be obtained with respect to the horizontal. This limits the movement of the offset arm 14 between the pre-engagement position and the engagement position for minimal mechanical stress. By having the horizontal offset arm 14 at the mating position, the electrical conductor 18 can be horizontally aligned as appropriate to ensure reliable electrical contact.

According to the example of Fig. 3, the connecting device has a pivotal connection P1 with an axis substantially parallel to the longitudinal axis X of the mechanical lift seat.

4, the connecting device comprises a flexible longitudinal element 22, the distal end of which is fastened to the proximal end of the offset arm 14 and the proximal end of the longitudinal element is connected to the suspension 4 . The flexible longitudinal element 22 corresponds to a leaf spring made of, for example, a metal or a composite material, so that the metal longitudinal element 22 is offset from the guide ramp 104 when it is at a predetermined distance from the guide ramp 104, And has the specificity of firmly supporting the arm 14.

As shown in Figs. 3 and 4, the connecting device may include a connecting arm 24. Fig. The connecting arm 24 is fixed with respect to the suspension 4. The connection arm has a distal end connected to the proximal end of the offset arm 14 and an inclined portion 26 extending to the proximal end. The butting member 16 is now fixed on the slope 26 so that the portion of the intermediate portion of the offset arm 14, that is, the portion between the proximal end and the distal end of the offset arm 14, Is supported by the member (16). The connecting arm 24 optionally fits into the shape of the suspension 4 and can be aligned along the suspension.

The distal end of the connecting arm 24 may be connected either directly by the pivot connection P1 or indirectly through the flexible element 22 to the proximal end of the offset arm 14. [ Where appropriate, the proximal end of the flexible element 22 is secured to the distal end of the connecting arm 24.

As shown in Figs. 3 and 4, the ramps 26 can extend substantially transversely, substantially opposite the direction in which the offset arms 14 extend.

The present invention also relates to a mechanical lift facility 100 comprising two end stations 102 connected by a public transport and carrying cable 10 shown in Figure 5, the aforementioned mechanical lift vehicle 1 And more particularly a mechanical lift seat and a guide ramp 104 which are substantially parallel to the air transport and carrying cable 10 on the offset arm 14 path of the mechanical lift vehicle 10 The offset arm 14 is displaced along the guide ramp 104 when the mechanical lift vehicle 1 passes the guide ramp 104 so that the offset arm 14 is displaced as a result of which the guard rail 12 A predetermined technical function, such as resetting the lock or unlocking of the battery, is performed.

The public transport and carrying cables 10 are supported by a pylon (not shown), for example, and are moved by a pulley 106 disposed at each end station 102.

The guide ramp 104 may be disposed in the boarding area 108 and / or the landing zone 110 of one of the end stations 102.

The guide ramp 104 may be disposed adjacent to a zone (not shown) adjacent to the exit zone 110 of one of the end stations 102, e.g., immediately adjacent to the exit zone of the exit zone 110, It is possible to unlock the guard rail 2 sufficiently early and to provide sufficient time to raise the guard rail once before leaving the vehicle 1 once the guard rail 2 is unlocked.

The guide ramp 104 includes a first ramp 112 disposed on the path of the offset arm 14 for guiding the offset arm 14 to the main portion 114 substantially parallel to the public transport and carrying cable 10 ).

1 to 5, the mechanical lift facility 100 includes two rows of conductive brushes 20 that are substantially parallel to one another and substantially parallel to the shipping and carrying cables 10, and two of the conductive brushes 20 All rows of columns may be placed on top of the guide ramp 104 to contact one of the electrical conductors 18 as the offset arm 14 slides along the guide ramp 104.

The two rows of the conductive brushes 20 are fixed on the guide lamp 104, for example.

Where appropriate, both rows of conductive brushes 20 are disposed above and / or below the main portion 114.

It should be noted that the mechanical lift facility 100 may correspond to a facility 100 of an inseparable type. That is, the mechanical lift facility 100 does not have a separation system of the mechanical lift vehicle 10.

Obviously, the invention is not limited to the embodiments described above, but such embodiments are given by way of example only. Modifications are possible, particularly in view of the configuration of the various components or by substitution of technical equivalents, without departing from the scope of protection of the present invention.

Therefore, the present invention is not limited to a mechanical lift seat but can be applied to, for example, a mechanical lift vehicle 1 of a gondola type.

Further, the predetermined technical function performed by displacement of the offset arm 14 at the mating position corresponds to a function other than locking or unlocking of the guard rail 2, such as opening one or several doors of a kevin, for example. can do.

Finally, the controller 12 may correspond to other types of control, such as cable control or hydraulic control, instead of onboard electrical sensors.
