Abstract

The cableway has at least one traction cable (5) between or below the carrier cables (3, 4) to engage with the cable clips of the car running gear, and at least one station at which the clips are released and the traction cable is diverted, while the carrier cables are taken on by rigid carrier rails (8-11). The traction cable passes below the carrier cables or rails.

Description

The present invention relates to a cable car with at least two spaced support cables per road side for cars with multi-track drives, at least one between the suspension ropes and / or below the same running Traction rope for the attack of cable clamps of the car, and at least a station in which a temporary solution of Rope clamps and a deflection of the pull rope is carried out, where appropriate the ropes in the station by rigid mounting rails are continued. The invention further relates to a Drive for a cable car specifically for such a Cable car is suitable, with a frame that is at least two spaced apart sides with rollers for unrolling equipped on the suspension ropes.

A cable car and a drive of the aforementioned Species are known from AT 104 465. In the known construction the hauling rope clamp is carried by the hanger of the wagon, which is rotatably hinged to the drive. This results each time the clamp is loosened and clamped on the pull rope, such as it occurs when braking and accelerating in the station, a Force transmission in the hanger. The introduction of force causes Vibration and pendulum movements of the pull rope, which can only be overcome by slowing down and accelerating is carried out slowly accordingly. This requires again correspondingly long braking and acceleration distances and additional guide rollers for the pull rope. Finally results itself by the force introduction into the hanger with the brakes and Accelerate a deflection of the hanger from the vertical, which leads to a height offset of the Klemmmaules, so that the risk of a failure of the traction cable when closing the Klemmmaules exists, which again only by additional guide rollers and an associated station extension could be reduced.

From DE 31 09 944 on the other hand, a material ropeway known with bulk containers, in which the bulk containers on both sides carry a drive, each on two suspension ropes with associated pull rope running. The tension cable clamp Although here is attached to the drive itself, but is in the known construction, the pull rope in the stations taken down and removed from the drive. This requires multiple deflections of the tension cables, which in turn the Station length increases, as explained in more detail below becomes.

Finally, cable cars with two suspension ropes and one Traction rope per lane side (so-called three-way lifts or 3S lanes) from EP 0 283 888. In the construction EP 0 283 888 seize the cable clamps of the drives Pull rope from the bottom, so that it in the stations for circulation must be deflected upward relative to the ropes.

For a more detailed explanation, reference is made to FIG. 1, which is a schematic perspective view of the cable guide in a head station of a three-lane track according to EP 0 283 888 shows. On each lane side 1, 2 are two support cables 3, 4 or 3 ', 4' are provided, which are parallel and in mutual horizontal distance run. Center and below the suspension cables runs the rotating traction cable 5. The suspension cables are in the Head station at 6, 7 after a short deflection down (Deflecting wheels not shown) guyed and formed by them Roadway for the cable car is by rigid mounting rails 8,9 or auxiliary mounting rails 10, 11 extended and recycled. The traction cable 5 runs in the station about a horizontal Deflection pulley 12, which also serve for the drive can. For this purpose, the traction cable after loosening the cable clamps in a Wagenauskuppelzone 13 above the road level and raised the height of the drives (14), namely because the drives of the known constructions the pull rope. 5 embrace from below.

This construction also has several disadvantages: on the one hand the height of the station is considerable. On the other hand are for the deflection of the pull rope up additional deflection rollers 15, 16 required, which the energy needs of Zugseilantriebes increased, a greater wear of the traction cable has the consequence and thus the life span and ultimately safety of the plant reduced. Finally, the numerous diversions require the Zugseiles a greater station length. Also, from DE-PS 858 706 such a cable car is known, in addition, the cable clamps are carried by the car drives.

Apart from that, there are also disadvantages on the part of Drive: Since the drive "pulls" the pull rope, as it were, the traction cable is out of its support rollers during a column crossing excavated. The extent of excavation is at least the overall height of the terminal construction of the drive in this area, e.g. 10 to 15 cm, which is the risk of a faulty Sliding back of the pull rope in his support rollers after The support crossing carries in itself.

The object of the invention is to provide a cable car and a corresponding drive therefor, with which the mentioned disadvantages can be overcome. This object is achieved in a first aspect of the invention with a cable car of the kind mentioned in the introduction, which is distinguished by the combination of the features,
that the traction cable in the station in a conventional manner revolves around a horizontal deflection plate whose diameter is smaller than the mutual distance of the carriageway sides, and
that the traction cable is guided in the course of its deflection on the facing support cables or rails below the same substantially horizontally.

With the help of this combination of measures will be the first time a significant reduction in the length and height of the station achieved: The direct mounting of the traction cable clamps to the Drives in conjunction with their bottom side arrangement and the lateral removal of the traction cable allows a considerable Reduction in the number of pull cable deflection pulleys required while maintaining the tensile rope stability. It results Immediately an extremely short station length. Specific Measures for lifting the pull rope above or below the plane the ropes omitted. Due to the lower number of Zugseilumlenkungspunkten also results in a lower energy consumption, a lower wear, a longer life and thus a greater security of the plant.

It is particularly favorable if the pull rope before and after its circulation around the deflection pulley each with deflection rollers vertical axis of rotation is guided, the pull rope from the Distract driving direction to make it on its way to and from the deflector under the facing ropes or rails pass by. This gives a minimum number of Deflections for the pull rope.

According to a preferred variant of the invention can be provided be that the suspension ropes or rails in the station in the area of loosening and / or reattaching the cable clamps learn an offset, which is maximum in the order the Zugseildurchmessers lies. As a result, the pull rope after opening the rope clamp relative to the open terminal jaw be slightly shifted so that an unimpeded deduction or exit of the traction cable made from the open terminal jaw can be, i. without rubbing on the jaws of the terminal muzzle, both at the side opening jaw (see, for example, Figs. 8, 9 later) and below opening jaw (see, for example, Fig. 10 later).

In a second aspect of the invention, the stated objects are achieved with a drive of the type mentioned in the introduction, which according to the invention is distinguished by the specific embodiment with the combination of features,
that the clamping jaw of the cable clamp is located on the underside of the frame, and
that the jaw mouth is below the rolling plane of the rollers and opens to the side.

This combination of features makes it possible for the first time direct the pull rope in the station directly and quietly laterally, without obstruction by the suspension ropes or rails, with all the advantages of a short station length. In addition, if the drive is a prop on the The track passes over, the traction cable only to a small extent from the Lifting rope guide rollers of the support dug: Since the clamp jaw lying on the bottom of the frame, lies the extent of the digging essentially only in the thickness of the jaws of the clamp mouth.

It is particularly favorable if the terminal jaw at the end of a is arranged substantially C-shaped arm, which from the bottom of the frame hinrakagt. With such a Clamp arm can drive under any pull rope hold down rollers become.

Furthermore, it is advantageous if the actuating device for the rope clamp at the top of the frame within the gauge of the drive is arranged. This reduces the required Clearance for the drive on the track and in the Station.

The rope clamp can be rigidly connected to the frame, which simplifies the construction. Alternatively, the rope clamp can be elastic be stored in the frame to make slight relative movements to be able to record while driving.

In any case, it is particularly favorable when the cable clamps is used as a removable unit in the frame. Thereby can drive with different types of cable clamps be equipped and vice versa. Other advantages are a simplified inspection and maintenance.

In a further variant of the invention, the frame bears Auxiliary rollers acting downward, the jaw of the Cable clamp also below the rolling plane of the auxiliary rollers lies. The auxiliary rollers are used to retract narrow curve radii in the station on corresponding auxiliary mounting rails while the rollers are disengaged, as known per se.

According to the invention, the terminal jaw is also below the Rolling plane of these auxiliary rolls arranged to an unhindered allow lateral removal of the traction cable.

It is preferably provided that from the top of the frame at least one guide pin, a guide roller od. Like. protrudes, which or which to rest on a support guide the station is determined. This allows any lateral forces in the ward, such as during exercise the rope clamp occur, are derived through the support guide.

A further advantageous embodiment of the invention is characterized in that the rollers in per se known Way at least in pairs in swivel cradles are mounted, and that at least two opposing one another Roller weighing connected to each other via an intermediate carrier which are pivotable about a direction parallel axis, preferably damped-springy, is mounted on the frame. Thereby can the drive get twisted while driving, so that inclinations of the drive in not exactly parallel Suspension cables are avoided. Also a rotation at least a single cradle by an additional horizontal Axle parallel to the road, also preloaded and damped is possible.

The invention will be described below with reference to the drawings illustrated embodiments explained in more detail. In the Drawings Fig. 1 shows a schematic perspective view the cable guide in a head station of a cable car after the Prior art, Fig. 2 is a schematic perspective view the cable guide in a head station of a cable car according to the Invention; Figs. 3, 4 and 5, the drive according to the invention in a side view, top view and front view, respectively, wherein Fig. 5 in addition some elements of the station shown in part Fig. 6 is a detail of the rolling of a roller on a mounting rail, Fig. 7 shows a variant of the storage of Casters on the drive in an end view, and Fig. 8 to 10 three different embodiments of rope clamps, the can be used in the drive of the invention.

The rope guide assembly according to the prior art according to Fig. 1 has already been discussed. In Fig. 2 are for those elements the cable guide assembly according to the invention, which those of Fig. 1 correspond to the same reference numerals; For the discussion of which is referred to FIG. 1.

The roadway and cable guide arrangement of FIG. 2 differs from that of Fig. 1 essentially by the Art the removal or uncoupling of the traction cable 5 in the station. In a Wagenentkuppelzone 21, in which the cable clamps of Cart drives are released from the traction cable 5, the pull rope is the fifth deflected substantially horizontally inwards.

The traction cable 5 occurs under the facing supporting cables 4, 4 'or this in the station extending support rails 9, 9 'over. The same is true for a car launch zone 21 'to, which is essentially mirror image of Wagenauskuppelzone 21 is designed so that in the further only on the right half of Fig. 2 is taken. To this end is on each lane side 1, 2 only a single sentence deflection rollers 22, 22 'with a substantially vertical axis of rotation required to pull the cable 5 horizontally to the deflection pulley 12 to distract.

The deflection plate 12 can be within and at the same height or preferably below that of the support rails 8, 9, 8 ', 9 'or the auxiliary support rails 10, 11, 10' extending the same, 11 'formed Umlenkbogens are arranged.

Basically, the pull rope from the Wagenauskuppelzone 21 down, diagonally down or even diagonally upwards be discharged when deflection rollers 22 with appropriately inclined Rotary axes are used and the deflection plate 12 accordingly is arranged, if necessary with the aid of auxiliary deflection rollers (not shown). The illustrated variant with lateral, in particular horizontal Zugseilentnahme leads to a particularly simple cable guide course for the Traction cable 5.

Figs. 3 to 5 show a specially for the road and Cable guide assembly of Fig. 2 suitable drive 31. Das Drive 31 is intended to be a cab (not shown) known manner on a (only partially shown) hanger Depend on 32 known type to form a cable car. The drive 31 comprises a frame 33, on which the hanger 32nd via a curved hanger arm 34 at a central hinge pin 35 acts from above as known in the art.

The frame 33 is on two spaced apart sides equipped with rollers 36 whose axes of rotation normal to Driving or longitudinal direction of the support cables 3, 4 are and on unroll the suspension cables 3, 4. In total, eight rollers 36 provided in pairs in roller rockers or weighing 37 are stored, which in turn each to a normal to Driving direction extending pivot axis 38 rotatably on the frame 33rd are stored. It is understood that other numbers of Rollers 36 can be provided, e.g. 4, 6, 12, 16 etc.

The frame 33 has (in the illustrated case of two cable clamps) two vertical openings 39 on, in each case a rope clamp 41 as a modular unit, i. removable and interchangeable, is used. Each rope clamp 41 is using anchored by bolts 43 in frame 33.

The structure of a cable clamp 41 is shown in Figs. 4 and 5 and in particular shown in Fig. 8. The rope clamp 41 has an approximately C-shaped arm 44 which in the assembled position of Rope clamp from the bottom 45 of the frame 33 projects downwards. The arm 44 supports a fixed jaw 45 and a movable jaw 46, which together form a clamping jaw 47, which is open at the side, i. attacks to the side.

For actuating the movable jaw 46, i. to open and closing the clamp mouth 47, is a clamp lever 48 provided by a mechanism (not shown) inside the arm 44, the jaw 46 drives. In Fig. 8 is the movable jaw 46 and the clamp lever 48 both in the closed position (solid lines) as well as the opened operating position (dotted lines) shown.

The clamp lever 48 is at its end with a roller 49th provided, which at the entrance and exit of the drive 31 in the Wageneinkuppelzone 21 or Wagenauskuppelzone 21 'on a corresponding control rail 50 (Fig. 5) runs and the clamp lever 48 actuated.

Figs. 9 and 10 show two alternative embodiments of cable clamps 41 ', 41 ". The cable clamp 41' of Fig. 9 has two movable jaws 46, 46 ', which open symmetrically and close to form the clamp mouth 47. The rope clamp 41 "of Fig. 10 is with just such jaws 46, 46 ' equipped, but their jaw 47 'opens downwards. It is understood that the terminal jaw 47 in any arbitrary other direction can open, if a corresponding lane offset is made, as will be explained later. For example, the terminal jaw 47 could also go upwards open, diagonally upwards or diagonally downwards.

Returning to Fig. 5, the frame 33 is at its top equipped with raised flanks 51, in which externally acting guide rollers 52 are mounted. The leadership roles 52 roll in the station on the terminal lever 48 facing away Side of the control rail 50 from. The flanks 51 and Guide rollers 52 thus act on the clamp lever 48 exerted Tilting moment and prevent a tilting movement of the Drive 31 when operating the cable clamps 41st

At the upper end of the flanks 51 friction plates 53 are mounted, which serve for the attack of friction wheels of the station, the the drive after loosening the cable clamp 41 through the station drive as known in the art.

In narrow curve radii in the station become the rollers 36 separated from the support rails 8, 9 and 8 ', 9' and the drive 31 runs on small auxiliary rollers 54 which are inside or are arranged outside the track of the rollers 36, on the auxiliary support rails 10, 11, 10 ', 11' from.

Fig. 5 shows the drive 31 while driving on the Support rails 8, 9 before reaching the auxiliary support rails 10, 11, but after the release and removal of the traction cable 5. The Traction cable 5 was horizontal inward in the direction of the arrow 55 removed from the clamp mouth 47. To prevent that Pulling cable 5 thereby at the edges of the clamping jaws 45, 46 and 46 ' strips, in this area the mounting rails 8, 9 a undergo slight misalignment, which is such a relative movement the drive 31 relative to the pull cable 5 causes the traction cable 5 is centered in the open clamping mouth 47. Of the In any case, the offset will be smaller than the diameter of the Traction cables 5 be, usually slightly larger than the height h of Edges of the jaws 45, 46, 46 'in their opened state, e.g. about 1/4 or 1/3 of the diameter of the pull rope. 5

If a rope clamp 41 is used, its clamp jaw 47 up or down opens, as the cable clamp 41 "of Fig. 10, a correspondingly larger roadway offset of Support rails 9, 10 are used to the traction cable 5 to the Jaws 45, 46, 46 'around so far from the clamp mouth 47 to free it to be in any direction, e.g. in the direction of the arrow 55 shown in FIG. 2, can be dissipated.

Fig. 5 also shows that the C-shaped design of the arm 44 of the cable clamp 41 serves to the passage of a pull rope Niederhalterolle 56 as they typically do is provided in the entrance area of a valley station. In Fig. 5 Finally, a roller 57 is indicated for the traction cable 5, from which the traction cable 5 at the drive crossing to a Extent d is excavated, which essentially by the Thickness of the jaw 45 is determined.

6 shows the embodiment of a mounting rail 8 (or 9) in detail. The groove bottom 58 of the track groove of a roller 36 can deepen due to wear over time, causing too misalignment of the drive in the station. To stop it, the surface profile of the Support rail 8 on both sides of a central region 8 ', the initially serves as a tread for the groove bottom 58, with Auxiliary running surfaces 8 "provided, the progressing depression the groove bottom 58 on the between the groove bottom 58th and the side walls 59 of the roller 36 remaining areas 60 come to the plant. These areas 60 of the roller 36 are subject to only a slight wear, so that the alignment of the drive 31 on the support rails 8, 9 then - after Wear of the groove bottom 58 - guaranteed for a long time remains.

Fig. 7 shows an alternative embodiment for storage the rollers 36 on the frame 33. Two opposing Roller weighing 37 are here on a separate intermediate carrier 61 stored, again about pivot axes 38th The intermediate carrier 61 is in turn about a direction of travel parallel Axis 62 pivotally mounted on the frame 33. Of the Subcarrier 62 can via springs 63 in a horizontal rest position preloaded and damped via dampers (not shown) be. It is sufficient, only on one side of the frame 33 an intermediate carrier 61 to provide such the possibility of distortion of the chassis formed by the rollers 36 create.

Alternatively or additionally, at least one of the rollers may be weighed 37 pivotable about a direction parallel axis on the intermediate carrier 61 (or on the frame 33, if no intermediate carrier 61 is used) may be stored.

The cable clamps 41 can be rigidly connected to the frame 33 be, as indicated by the bolt 43. Alternatively you can they are elastic, e.g. springy, preferably damp-springy, in the frame 33, e.g. with the help of elastic rubber bushes, in which the bolts 43 are stored to absorb vibrations or to dampen.

A transverse oscillation of the hanger 32 about the hinge pin 35th can via a corresponding spring element, preferably damping spring element, counteracted, e.g. a torsion spring or a torsion damping element, as indicated at 64 is.

The rollers 36 may eventually weigh in the rollers 37 be slidably mounted in the direction of their axes of rotation, so that the drive 31 larger radii of curvature of the support cables 3, 4th or support rails 8, 9 may follow as known in the art.

It is also possible in principle, more than a pull rope per lane side, e.g. two pull ropes per lane side (so-called 4S lane), e.g. horizontally from each other are spaced. In this case, all tension cables in the course their deflections in the station simultaneously or sequentially on the suspension ropes or rails below the same past. The drive is in this case with a equipped with corresponding higher number of cable clamps, which the traction cables with corresponding mutual offset take, i. the terminal jaws are horizontal accordingly staggered.

Also it is possible to have more than two suspension ropes per lane side to be provided, e.g. three or four. It is understood that in In this case, the drives accordingly multi-lane are, i. equipped with rollers, which in several spaced apart, each aligned in the direction of travel Rows lie.

The invention is of course not on the illustrated Embodiments limited, but includes all variants and modifications included in the framework of the Claims fall.
