Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for transporting goods or people by means of an aerial ropeway.

[Conventional technology]

BACKGROUND OF THE INVENTION Devices for transporting goods and persons by means of aerial ropeways are already known, of the type comprising one or more supporting traction aerial ropes. The aerial rope extends between two end stations for loading or boarding and for unloading or disembarking, optionally with one or more intermediate stages, and between said two stations. It is supported and guided by a plurality of support rollers and compression rollers supported by one or more, generally several, pylons distributed over the entire length. One or more vehicles, more particularly cabins, are removably attached to said aerial rope.

The device may be of the pulsating or reciprocating type or of other types.

[Problem that the invention seeks to solve]

A plurality of rollers are often combined in pairs. In other words, a plurality of rollers are placed on both ends of the first stage balancer 4-, and the first stage balancer i4- is supported by both ends of the second stage i4 lanper at its center position and is rotatable. Similarly, the balance t+- of the second stage is supported at both ends of the third stage nozzle lance at its center position and is rotatable. The number of stages of the balance bar is determined by the number of rollers used, and the final /J silamper forms a beam supported on the tower bracket at its central location. This type of structure has the advantage of being a standardized structure, with multiple rollers following the progress of the rope, resulting in an even distribution of load on the multiple rollers when the rope is under load. have This structure has a unit weight of between approximately 300 kliF and 1.5 tons for the plurality of cabins, and approximately 1.5 tons for two adjacent cabins.
Particularly suitable for distributed (i.e. dispersed) loads such as those separated from each other by a distance of approximately 45 m (a value corresponding to an average distributed load of the order of 30 m/m). ing.

However, this mechanism has significant drawbacks if the device encounters concentrated or undistributed loads. In this case, on the one hand, the load is relatively large, more specifically of the order of 1.5 to 2.5 tons per meter length, and on the other hand, the load is limited to a limited length, more specifically of the order of 3 to 2.5 tons per meter length. concentrated over a length on the order of 6 m.

This occurs when large cabins are placed very close to each other. Under these circumstances, the concentrated load on the rope causes the rope to move rapidly and with large amplitude when a vehicle passes on the other side of the tower. This imparts a rocking motion to the vehicle, and if the width of the vehicle is a passenger cabin, said rocking motion is a very troublesome problem, resulting in an uncomfortable ride for the passengers. It turns out. This drawback becomes greater as the linear velocity of the rope increases.

The present invention aims to provide a solution to these drawbacks.

[Means for solving problems]

For the above purpose, the present invention provides that the tower is supported by at least one bracket and that the tower is supported by a plurality of rollers, either as individual rollers or as a group, of adjacent rollers or adjacent groups of rollers. The structure includes a fixed beam on which a plurality of rollers are supported so that the rollers are supported independently, and the plurality of rollers support the rope in order to prevent sudden and large amplitude movement of the rope when the plurality of car ends pass on the other side of the steel tower. A device of the type described above is provided which restricts the progression of the rope, having the function of at least partially restraining the progression.

On the other hand, the construction of devices of this type according to the invention cannot be completely standardized, as is often desired by designers and engineers, but must be calculated and applied in each particular case. No. Similarly, the load need not be evenly distributed over the rollers, contrary to the common assumption of designers and engineers.

〔Example〕

The present invention will be described in detail below with reference to the accompanying drawings showing one embodiment of the conveyance capacity of the present invention.

FIG. 1 shows a device for transporting goods or persons by means of an aerial ropeway of the type comprising one or more supporting tensions 9 and intermediate ropes 1, said aerial ropes 1 possibly having one or more intermediate stations. (not shown) extending between two end stations for loading or boarding and for unloading or disembarking, and generally one or more end stations distributed between said two stations. is supported and guided by a plurality of support rollers and compression rollers 3 supported by several steel towers 4. One or more vehicle widths, more specifically cabins, are removably attached to the aerial rope 1.

The device is made of the pulsating or reciprocating type, or of the type that will be referred to below with respect to its "concentrated load" nature. The device comprises one or more bearing tension ropes or several similar rows f, each of which is a bearing tension rope. Although the rope will not be described in detail herein, it can be used in a variety of modifications.

As mentioned above, the device according to the invention is of the blood-loading type. That is, for the distribution of the vehicles 5 along the rope 1 and the capacity of the vehicles @ 5, the loads they exert on the rope 1 are on the one hand quite large;
More specifically, it is on the order of 11+1.5 to 2.5 tons per meter length, and on the other hand, the load is concentrated over a limited length, more specifically on a length of the order of 3 to 6 meters. . Concentrated loads in the device are caused by a plurality of cabins 3, for example three cabins arranged close to each other and possibly connected to each other.

The values given above should not be considered as constrained or limited values. However, with the device according to the present invention, the average value of the distributed load is 30 k per 1 m length of rope.
F order, and the average distance between vehicles is 15 to 4
A comparison can be made with previously known devices with distributed loads such as 5 m.

Preferentially, the charges according to the invention are also of the high-speed running type, the running linear velocity of the rope I being between 7 and 8 m per second, more particularly 7.5 m/sec or of the order thereof. .

According to the invention and as shown in FIGS. 2 and 3, at least one fixed beam 6 is supported on the tower 4 via at least one bracket 7, the fixed beam A plurality of rollers 3 (support rollers or compression rollers) are placed on top.

The plurality of rollers 3 may be arranged singly or in groups, such as in a pair as in the illustrated example. The rollers 3 are completely independent of adjacent rollers or roller groups. (This is true of known devices in which a plurality of rollers are kinematically combined with each other by rotatable first and second stage balancers, etc., from one end of a set of rollers to the other. ) This structure has the function of at least partially restraining or restricting the progression of the rope. (This is contrary to the case of the prior art in which it is the advancement of the rope that determines the position of the plurality of rollers.) Therefore, when the plurality of vehicles 5 pass on the other side of the steel tower 4, the rope This makes it possible to prevent sudden and large amplitude fluctuations tS of 1.

Thus, according to the invention, a plurality of vehicles @ 5 constituting a concentrated load are influenced by the rocking motion when passing behind the tower 4 at the real time when the vehicles 5 create a concentrated load on the rope 1. be prevented from doing so.

A plurality of rollers 3 are placed on the fixed beam 6 Vc along a curve indicated by C. This reference curve C is an intermediate curve between a plurality of curves corresponding to a plurality of different possible load values. Song+file may correspond, for example, to the condition in which the rope 1 receives a maximum charge. This curve C may correspond to either a specific or hypothetical load value between various possible load values, depending on the configuration of the device.

This curve C is determined by calculations for each particular situation. In some cases, this curved bowl will be concave, curved upward or downward, or it may approximate a parabola or catenary. In other cases,
The curve may have a complex shape.

Preferably and also for strength reasons, the curve C runs in the central part of the fixed beam 6. To this end, the fixed beam will have a more or less complex shape depending on the individual case.

More particularly, the fixed beam 6 may generally have the shape of a cylindrical segment, which makes it possible to use the segment with different reference curves. This feature, which makes possible a certain standard, is illustrated in FIG. 4, in which the same fixed beam 6 is connected to several, in this case three, reference pieces JC1*C2* Indicates that C5 can be placed. The plurality of rollers 3 are distributed uniformly or non-uniformly along the reference curve C, as desired.

According to a possible variant, not shown, the axes 3 a of the rollers 3 are fixedly mounted on the fixed beam 6 . In this case, the rows 23 have only one envelope curve that contacts the rollers 3.

According to another possible variant as shown in FIG.
The shafts 3& of the plurality of rows 23 are movably mounted on the fixed beam 6. Some of these rows 23 or rollers 3 will have multiple envelope curves. For this purpose, a plurality of rollers 3 are arranged on a plurality of axes 3a
It is preferably supported by a balance bar 8 which is rotatable on a fixed beam 6 about an axis 8a parallel to . In one possible embodiment, the balance bar 8 carries two rollers 3 arranged at each end 8b of its par;
The pivot 8a of the balance bar 8 is located at the center 8 of the balance bar 8.
It is located at c. This device is capable of handling a rope 1 and a plurality of rollers 3 under various possible loading conditions of the rope 1.
This allows for certain standard arrangements that ensure minimal contact between the two.

It is clear that the balancing gear 8 may accommodate different numbers of rollers. Alternatively, the fixed beam 6 may accommodate a suitable number of rollers, from several, for example eight, to several tens, for example up to thirty. The length of the fixed beam 6 is thus varied depending on the number of rollers.

When using several parallel ropes l, several fixed beams connected by spacer members are provided, or one fixed beam having a V-shaped (or inverted V-shaped) cross-section is provided. .

If necessary, the device may comprise means for forming an abutment surface for limiting the rotation of the balance bars 8 or conventional return means for biasing the balance bars 8 towards their original position. good.

FIG. 5, shown as a hypothetical case solely for the sake of the drawing, shows the set of rollers 3 of FIG. 2 in a different form. In other words, all of the plurality of rows 23 in FIG. 2 are loaded, whereas in FIG. 5, some rollers are not loaded. Some or all of the balance gears 8 are pivoted about their axis 8a so as to form a new envelope curve in response to the progression of the low f1.

In this situation, some rollers 3 are in contact with the rows 761 with different values of pressure, while other rows 23 are separated from the rope and are therefore inactive.

This arrangement is acceptable for cases where there is no sudden and large amplification movement of low fl.
