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 apart suspension cables per side of the carriageway for cars with multi-track drives, at least one running between the suspension cables and / or below them Traction rope for the attack of rope clamps of the wagons, and at least a station in which a temporary solution to the Rope clamps and a deflection of the pull rope takes place, where appropriate the suspension cables in the station by rigid mounting rails are continued. The invention further relates to a Drive for a cable car, specifically for one Cable car is suitable, with a frame that is at least on two spaced sides with castors for rolling on the suspension cables.

A cable car and a drive of the introduction Kind are known from AT 104 465. With the known construction the traction rope clamp is carried by the car's hanger, which is pivoted to the drive. This gives each time the clamp is loosened and clamped, such as it occurs in the station when braking and accelerating, one Force transmission into the hanger. The introduction of force causes Vibrations and pendulum movements of the pull rope, which can only be remedied by braking and accelerating is carried out accordingly slowly. Again, this requires correspondingly long braking and acceleration distances and additional guide rollers for the pull rope. Finally results by applying force to the hanger when braking and Accelerate a deflection of the hanger from the vertical, which leads to a height offset of the terminal mouth, so that the danger of missing the pull rope when closing the Terminal jaws exist, which again only by additional guide roles and an associated station extension could be reduced.

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

After all, cable cars are with two suspension ropes and one Traction rope per lane side (so-called tricable ropeways or 3S lanes) are known from EP 0 283 888. During construction in EP 0 283 888 the cable clamps of the drives do this Pull rope from below, so that it is in the stations for circulation must be deflected upwards relative to the suspension cables.

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 tricable ropeway according to EP 0 283 888 shows. On each side of the road 1, 2 there are two suspension cables 3, 4 or 3 ', 4' provided in parallel and at a mutual horizontal distance run. In the middle and below the suspension cables runs the revolving pull rope 5. The suspension ropes are in the Head station at 6, 7 after a short deflection downwards (Deflection wheels not shown) braced and the one they formed The carriageway for the cable car is made by rigid support rails 8.9 or auxiliary support rails 10, 11 extended and recycled. The pull rope 5 runs in the station around a horizontal Deflection plate 12, which also serve for the drive can. For this purpose the pull rope is released after loosening the rope clamps in a car disengagement zone 13 upwards over the road level and the height of the drives raised (14), namely because the drives of the known constructions the pull rope 5 reach 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 what the energy requirement of the traction cable drive increased, leads to greater wear of the pull rope and thus the lifespan and ultimately the safety of the system reduced. Finally, the numerous redirections require of the pull rope a longer station length.

Apart from that, there are also disadvantages on the part of the Drive: Since the drive "goes underneath" the pull rope, so to speak, the pull rope becomes from its support rollers when the supports are crossed excavated. The extent of the excavation is at least the total height of the terminal construction of the drive in this area, e.g. 10 to 15 cm, which increases the risk of faulty The traction rope slides back into its support rollers the column crossing contains.

The aim of the invention is to create a cable car and a corresponding drive for it, with which the disadvantages mentioned can be overcome. This goal is achieved in a first aspect of the invention with a cable car of the type mentioned in the introduction, which is characterized by the combination of the features,
that the cable clamps are carried by the carriage drives,
that the traction rope rotates in the station in a manner known per se around a horizontal deflection disc, the diameter of which is smaller than the mutual distance between the sides of the road, and
that the traction cable in the course of its deflection on the mutually facing support ropes or rails is guided below it substantially horizontally.

With the help of this combination of measures is the first time a substantial reduction in the overall length and height of the station achieved: The direct mounting of the pull rope clamps on the Drives in connection with their underside arrangement and the lateral removal of the pull rope allows a considerable Reduction in the number of required pull rope pulleys while maintaining the rope stability. It follows an extremely short station length. Specific Measures to lift the pull rope above or below the level the suspension ropes are omitted. Due to the lower number of pull rope diversion points there is also less energy consumption, less wear, longer life and thus greater security of the system.

It is particularly favorable if the pull rope before and after its rotation around the deflection pulley with deflection rollers vertical axis of rotation is guided, which pull the rope from the Deflect the direction of travel to keep it on its way to and from the baffle under the facing ropes or - seemed to lead past. This results in a minimal number of Deflections for the pull rope.

According to a preferred variant of the invention can be provided be that the suspension cables or rails in the station in the area of loosening and / or re-engaging the rope clamps experience an offset which is at most in the order of magnitude of the rope diameter. This allows the traction rope to the opening of the rope clamp relative to the open jaw be moved slightly so that an unimpeded deduction or the pull rope emerges from the open terminal mouth can be, i.e. without touching the jaws of the terminal jaw, both with the terminal jaw opening laterally (see later e.g. Fig. 8, 9) as well as with down opening jaw (see later e.g. Fig. 10).

In a second aspect of the invention, the stated objectives are achieved with a drive of the type mentioned in the introduction, which is distinguished according to the invention by the special embodiment with the combination of the features,
that the frame between the rollers carries at least one actuatable cable clamp for releasably gripping the pulling cable by means of a clamping jaw,
that the clamp mouth of the cable clamp is on the underside of the frame, and
that the clamp jaw lies below the rolling level of the rollers and opens to the side.

With this combination of features it is possible for the first time to lead the pull rope directly and quietly to the side in the station, without hindrance due to the suspension cables or rails, with all the advantages of a short station length. In addition, if the drive is a prop on the The route traverses, the pull rope only to a small extent by the Lifting rope guide rollers of the support lifted: Since the clamp jaw lies on the underside of the frame, the extent of the excavation essentially only in the range of the thickness of the jaws of the terminal mouth.

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

It is also advantageous if the actuating device for the rope clamp on the top of the frame within the track gauge 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 slight relative movements to be able to record while driving.

In any case, it is particularly convenient if the rope clamps is used as a removable unit in the frame. Thereby can drives with different types of rope clips be equipped and vice versa. Additional advantages are a simplified control and maintenance.

In a further variant of the invention, the frame bears Auxiliary rollers that act downwards, the jaws of the Rope clamp also below the unwinding level of the auxiliary rollers lies. The auxiliary rollers are used to negotiate tight curve radii in the station on corresponding auxiliary mounting rails while the rollers are disengaged, as is known in the art.

According to the terminal mouth is also below the Unwind level of these auxiliary rollers arranged to an unimpeded allow lateral removal of the pull rope.

It is preferably provided that from the top of the frame at least one guide pin, a guide roller or the like. towers up which one or all to bear on a support guide the station is determined. This can cause any transverse forces in the station, such as during operation the rope clamp occur, are derived via the support guide.

Another advantageous embodiment of the invention is characterized in that the rollers in known per se At least in pairs in swiveling roller cradles are mounted, and that at least two opposite one another Roller cradles connected to each other via an intermediate support which are pivotable about an axis parallel to the direction of travel, preferably cushioned-resilient, is mounted on the frame. Thereby the drive can twist while driving, so that inclinations of the drive with not exactly parallel Ropes are avoided. Even a rotary movement at least a single roller cradle with an additional horizontal one Axle parallel to the road, also preloaded and damped is possible.

The invention is illustrated below in the drawings illustrated embodiments explained in more detail. In the 1 shows a schematic perspective view the cable routing in a head station of a cable car after the PRIOR ART, Fig. 2 is a schematic perspective view the cable routing in a head station of a cable car according to the Invention; 3, 4 and 5 the drive according to the invention in a side view, top view or end view, wherein in Fig. 5 also partially shows some elements of the station 6 is a detail of the rolling of a roller on a mounting rail, Fig. 7 shows a variant of the storage of Rollers on the drive in a front view, and Fig. 8 to 10 three different embodiments of rope clips that can be used in the drive of the invention.

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

The roadway and cable guide arrangement of Fig. 2 differs differs from that of FIG. 1 essentially by the type the removal or uncoupling of the pull rope 5 in the station. In a wagon uncoupling zone 21, in which the cable clamps of the Carriage drives are detached from the pull rope 5, the pull rope 5 deflected substantially horizontally inwards.

The pull rope 5 occurs under the mutually facing support ropes 4, 4 'or the mounting rails extending them in the station 9, 9 'over. The same applies to a car engagement zone 21 ', which is essentially a mirror image of the car disengaging zone 21 is designed so that in the following only on right half of Fig. 2 is referred. To this end is only one sentence on each side 1, 2 of the road of deflection rollers 22, 22 'with a substantially vertical axis of rotation required to pull the rope 5 horizontally to the deflection pulley 12 to distract.

The deflection plate 12 can be inside 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' which extend them, 11 'formed bend can be arranged.

Basically, the pull rope can be removed from the car disengaging zone 21 downwards, downwards or even upwards be removed when deflecting rollers 22 with correspondingly inclined Axes of rotation are used and the deflection plate 12 accordingly is ordered, if necessary with the help of auxiliary deflection rollers (not shown). The variant shown with lateral, especially horizontal pull rope removal leads to a particularly simple course of the rope guide for the Pull rope 5.

3 to 5 show a specially for the road and 2 suitable drive 31. The Drive 31 is intended to be a cabin (not shown) known type over a (only partially shown) hanger 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 on a central hinge pin 35 attacks from above, as is known in the art.

The frame 33 is on two spaced sides equipped with rollers 36 whose axes of rotation are normal to Travel or longitudinal direction of the suspension cables 3, 4 and on unroll the suspension cables 3, 4. There are a total of eight casters 36 provided, each in pairs in roller rockers or cradles 37 are stored, which in turn each by a normal to Pivot axis 38 extending in the direction of travel can be rotated on frame 33 are stored. It is understood that other numbers of Casters 36 can be provided, e.g. 4, 6, 12, 16 etc.

The frame 33 has (in the case shown two rope clamps) two vertical openings 39 in each a rope clamp 41 as a modular unit, i.e. removable and interchangeable, is used. Each rope clamp 41 is with the help anchored by bolt 43 in the frame 33.

The construction of a cable clamp 41 is in FIGS. 4 and 5 and shown in particular in FIG. The cable clamp 41 has an approximately C-shaped arm 44 which in the mounting position of the Cable clamp protrudes downward from the underside 45 of the frame 33. The arm 44 supports a fixed jaw 45 and one movable jaw 46, which together form a jaw 47, which is open on the side, i.e. reaches to the side.

To actuate the movable jaw 46, i.e. to open and closing the clamp jaw 47 is a clamp lever 48 provided, via a (not shown) mechanism inside the arm 44 drives the jaw 46. In Fig. 8 are the movable jaw 46 and the clamp lever 48 both in the closed rest position (solid lines) as well as the open operating position (dotted lines) shown.

The clamp lever 48 has a roller 49 at its end provided, which when entering and exiting the drive 31 in the car coupling zone 21 or car coupling zone 21 'on one corresponding control rail 50 (Fig. 5) and the clamp lever 48 operated.

9 and 10 show two alternative embodiments of rope clips 41 ', 41 ". The rope clip 41' of FIG two movable jaws 46, 46 'that open symmetrically and close to form the jaw 47. The rope clamp 41 "of FIG. 10 has the same jaws 46, 46 ' equipped, their terminal mouth 47 'opens downwards. It it goes without saying that the terminal jaw 47 also in any can open in another direction, provided there is a corresponding lane offset is made, as will be explained later. For example, the terminal jaw 47 could also go upward open, diagonally upwards or diagonally downwards.

Returning to Fig. 5, the frame 33 is on its top equipped with raised flanks 51, in which after 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 Counterturning moment and prevent a tilting movement of the Drive 31 when the cable clamps 41 are actuated.

At the upper end of the flanks 51, friction plates 53 are mounted, which are used to attack the station’s friction wheels the drive after the cable clamp 41 has been released by the station drive as known in the art.

The rollers are in tight curve radii in the station 36 separated from the mounting 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 width of the rollers 36 the auxiliary mounting rails 10, 11, 10 ', 11'.

Fig. 5 shows the drive 31 while driving on the Mounting rails 8, 9 before reaching the auxiliary mounting rails 10, 11, but after loosening and removing the pull rope 5. Das Pull rope 5 was horizontally inward in the direction of the arrow 55 discharged from the terminal jaw 47. To prevent that Pull rope 5 at the edges of the clamping jaws 45, 46 or 46 ' grazes, in this area the mounting rails 8, 9 a undergo slight offset, which such a relative movement of the drive 31 opposite the pull rope 5 causes the pull rope 5 is centered in the open jaw 47. The In any case, the offset becomes smaller than the diameter of the Pull rope 5 be, usually slightly larger than the height h of Edges of the clamping jaws 45, 46, 46 'in their open 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 mouth 47 opens up or down, like the cable clamp 41 "from Fig. 10, a correspondingly larger road offset Support rails 9, 10 are used to pull the rope 5 around the Clamping jaws 45, 46, 46 'around as far out of the clamping jaw 47 free that it is in any direction, e.g. in the direction of the arrow 55 according to FIG. 2, can be discharged.

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

6 shows the design of a mounting rail 8 (or 9) in detail. The groove base 58 of the track groove of a roller 36 can deepen due to wear over time, leading to misalignment of the drive in the station. In order to stop this, 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 base 58 with Auxiliary treads 8 "provided that as the deepening progressed of the groove base 58 on that between the groove base 58 and the side rims 59 of the roller 36 remaining areas 60 come to the plant. These areas 60 of the roller 36 are subject to little wear and tear so that the alignment of the drive 31 on the mounting rails 8, 9 then - after Wear of the groove base 58 - guaranteed for a long time remains.

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

Alternatively or additionally, at least one of the rollers can be weighed 37 can be pivoted about an axis parallel to the direction of travel on the intermediate support 61 (or on the frame 33 if no intermediate support 61 is used).

The cable clamps 41 can be rigidly connected to the frame 33 be, as indicated by the bolts 43. Alternatively, you can they are elastic, e.g. springy, preferably cushioned-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 swinging of the hanger 32 around the hinge pin 35 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 can finally be weighed in the rollers 37 slidably mounted in the direction of their axes of rotation, so that the drive 31 larger radii of curvature of the supporting cables 3, 4th or support rails 8, 9 can follow, as known in the art.

In principle, it is also possible to have more than one pull rope to be provided per side of the road, e.g. two pull ropes per side of the road (so-called 4S-Bahn), which e.g. horizontally from each other are spaced. In this case, all traction ropes are in the course their diversions in the station simultaneously or successively on the supporting cables or rails below the same past. In this case, the drive comes with a correspondingly higher number of rope clamps, which the pull ropes with corresponding mutual offset seize, i.e. the jaws are accordingly horizontal staggered.

It is also possible to have more than two suspension cables per side of the road to be provided, e.g. three or four. It is understood that in in this case, the drives are designed to be multi-track become, i.e. are equipped with casters, which in several spaced from each other, each aligned in the direction of travel Rows lie.

The invention is of course not limited to that shown Embodiments limited, but includes all variants and modifications included in the scope of the Claims fall.
