SAFETY SYSTEM FOR A CABLE CAR

Description

background

[0001] The present invention relates to a safety system for a cable car comprising at least one rope catching device and a deflector. State of the art

[0002] EP 2 792 566 B1 discloses a cable arrester for monocable railways, which serves as a safety device to prevent accidents in the event of cable derailments. The cable arrester serves to hold a supporting cable, which is lifted from the cable support rollers by the pendulum movements of the gondolas or chairs attached to the supporting cable. The cable arrester according to EP 2 792 566 B1 comprises a first cable arrester tray and a second cable arrester tray, so that a cable that bounces off the first cable arrester tray due to excessive force can be captured in the second cable arrester tray and held in the three-point support of the second cable arrester tray.

[0003] It has been shown that even suspension cables derailed at high wind speeds are captured in one of the cable arrester shells by this previously known cable arrester. However, high wind speeds, for example caused by storms, lead to pendulum movements of the gondolas or chairs, resulting in a deflection of more than 20 degrees relative to their normal position, and circular oscillations, which can exert such high forces on the suspension cable that it is damaged upon impact with the cable arrester.

[0004] One possible solution to this problem, according to patent US 3,274,924, is to install an electrical switch on the cable tray. This switch interrupts the contact for the cable drive if a cable derails and thus comes to rest on the cable tray. A similar solution is shown in document AT 373 832 B. The cable car operation is thus abruptly interrupted by the electrical switch in an emergency stop. Therefore, considerable forces act on the cable when the cable derails and also during an emergency stop, so the possibility of damage to the cable cannot be ruled out.

[0005] To prevent damage to the rope, CN 203381624U proposes a support surface for the rope in a rope catch tray, which is mounted in a support element by means of a spring element. If the rope derails and hits the support surface, the spring element is compressed and the impact is cushioned in the vertical direction. However, during a derailment, the rope is sometimes subjected to considerable transverse forces, for which this rope catch tray is not designed. Furthermore, the cushioning is insufficient if the spring element is not dimensioned for the considerable impact forces that occur, meaning that the spring element cannot adequately absorb such an impact. If, on the other hand, the spring element is dimensioned to adequately cushion the impact force, the spring element resets when the impact force is removed, thus creating the risk that the rope will jump out of the rope catch tray again.As a result, there is still a risk of the rope completely derailing. Object of the invention

[0006] The object of the invention is to provide a safety system for a cable car comprising at least one rope catching device and a deflector, by means of which damage to the supporting cable can be avoided. Description of the invention

In particular, one of the first or second profile elements contains aluminum or a high-strength steel.

[0019] According to one embodiment, the fastening element comprises at least two clamping screws in order to connect the band element to a counter element located on the opposite side of the support arm.

[0020] A non-claimed rope catching device for a cable car contains a rope catching tray having a support surface for a rope, wherein the support surface contains a damping element. The rope catching device is part of a safety system for the cable car. An existing cable car can be retrofitted with a rope catching device. It is also possible to equip existing rope catching devices with a damping element according to one of the embodiments. The rope catching device can also be used for a ski lift. The rope catching device can, in particular, contain a metal; for example, at least the rope catching tray can comprise a cast element.

[0021] According to one embodiment, the damping element comprises a coating on the support surface, which can at least partially absorb the impact force acting upon the rope impacting the rope catch tray. In particular, the damping element can contain a polymer, wood-based materials or wood, or an elastomer, for example rubber. Wood-based materials can be understood to mean, for example, chipboard, wood fiber materials, for example MDF boards. For example, the coating can contain a polymer, in particular a weather-resistant polymer. The polymer can in particular comprise a thermoplastic polymer. The coating can be formed as a single layer. The layer can comprise several sublayers. Each of the sublayers can contain a different material or contain a material whose properties differ in each sublayer.For example, at least two sub-layers can be provided which have different hardnesses.

[0022] The layer is in particular applied to the surface of the rope catch tray. In particular, the layer can at least partially absorb an impact from a rope that impacts the layer. The layer can have a layer thickness in the range from 0.5 mm up to and including 4 mm. For example, the damping element can contain polyurethane. In particular, the coating can contain polyurethane.

[0023] In particular, the polyurethane may exhibit a rebound of approximately 45%. The rebound is determined in particular according to ASTM D-2632. In particular, the polyurethane may exhibit a compression set of 27% according to ASTM D-395 after 22 hours at a temperature of 70 degrees Celsius and 25% compression set.

[0024] The safety system can also be used for a ski lift.

[0025] A non-claimed deflector for a support arm of a cable car conveyance for moving the support arm past a cable arrester comprises a fastening element for attachment to the support arm and a deflection element. The deflection element is designed as a band element which projects beyond the support arm in the direction of travel and against the direction of travel. The band element can in particular be designed as a profile element. According to one exemplary embodiment, the band element contains a profile element which has a closed profile cross-section. According to one exemplary embodiment, the band element comprises a plurality of profile elements lying on top of one another. In particular, the band element comprises a first profile element which has a greater length than a second profile element. In particular, the second profile element is arranged between the first band element and the support arm.According to this exemplary embodiment, the second profile element is designed to rest on the support arm. According to one exemplary embodiment, the second profile element contains aluminum. The second profile element according to this exemplary embodiment therefore not only contributes to increasing the dimensional stability of the band element, but also serves as an indicator element. If the deflector impacts a cable arrester due to a pendulum movement of the support arm, the band element can be deformed. The first profile element, which usually contains a ferrous material, in particular steel, is deformed when the support arm impacts the cable arrester. The deformation is reversible because it is a deformation that lies within the elastic range of the first profile element. The deformation is transferred to the second profile element because it rests on the first profile element and is connected to it.However, the deformation leads to at least partial plastic deformation of the second profile element if it contains aluminum. This deformation of the second profile element is therefore at least partially irreversible and detectable when the module deflector is subjected to testing. This allows a defective module deflector to be replaced before excessive stress on the first profile element can occur, leading to potential breakage of the first and / or second profile element.

[0026] According to one embodiment, the belt element has an end region extending in the direction of travel of the support arm, which encloses an angle to the direction of travel that is greater than zero degrees and less than 60 degrees. Furthermore, the belt element can have an end region extending opposite to the direction of travel of the support arm, which encloses an angle to the direction of travel that is greater than 0 degrees and less than 60 degrees. In particular, the angle or each of the angles can be in the range up to and including 30 degrees.

[0027] According to one embodiment, the fastening element comprises two clamping screws that connect the band element to a counter element located on the opposite side of the support arm. Brief description of the drawings

Detailed description of the drawings

[0029] Fig. 1ashows a cable arrester 10 for a cable car, comprising a cable arrester tray 2, which has a support surface 3 for a cable 5, wherein the support surface 3 contains a damping element 4. The cable arrester 10 serves to arrest and hold the cable 5, which is used as a supporting cable, in the event of a cable derailment. The cable arrester 10 is a component of a safety system for the cable car. An existing cable car can be retrofitted with a cable arrester 10. It is also possible to equip an existing cable arrester 10 with a damping element 4 according to one of the embodiments. The cable arrester 10 according to Fig. 1ais attached to a rocker support beam, on which the cable support rollers (not shown in this figure) are also mounted on a cable support roller rocker. The cable catching device 10 is arranged laterally adjacent to the cable support rollers. The cable catching device 10 contains a support element 6, which is connected to the cable catching tray 2. The support element 6 contains a bore 7, which is designed to receive a bolt 8, which is part of a bolt connection. By means of the bolt connection, the cable catching device 10 can be pivotally connected to the rocker support beam.

[0030] The rope catch tray 2 has an inwardly directed bend 9, so that the rope catch tray 2 together with the support surface 3, the stop wall 11 and the corresponding bend 9 each form a three-point support for the rope 5.

[0031] Fig. 1b shows a detail of the Fig. 1a, which shows a section of the rope catch tray 2 of the rope catch device 10. According to the present exemplary embodiment, the damping element 4 comprises a coating on the support surface 3, which can at least partially absorb the impact force acting upon the impact of the rope 5 on the rope catch tray 2. In particular, the damping element 4 can contain a polymer, wood, or an elastomer. For example, a coating can be provided which contains a polymer, in particular a weather-resistant polymer. The coating can be formed as a single layer or comprise a plurality of layers. The layer is applied in particular to the support surface 3 of the rope catch tray 2. In particular, the layer can at least partially absorb an impact of a rope 5 which impacts the layer. The layer can have a layer thickness in the range from 0.5 mm up to and including 4 mm.The layer may in particular have a layer thickness in the range of 0.5 mm up to and including 2.5 mm.

[0032] For example, the damping element may contain polyurethane. In particular, the coating may contain polyurethane. In particular, the damping element may have a hardness of up to 90 Shore.

[0033] Fig. 2 shows a rope catching device 20 according to a second embodiment, which differs from the previously described rope catching device 10 in that a first rope catching bowl 2, as in Fig. 1a described, and a second rope catching tray 12, which in the installed state is arranged below the first rope catching tray 2. The rope catching device 20 according to Fig. 2is attached to a rocker support beam, on which the cable support rollers (not shown in this figure) are also mounted on a cable support roller rocker. The cable catching device 20 is arranged laterally adjacent to the cable support rollers. The cable catching device 20 contains a support element 16, which is connected to the first cable catching tray 2. The support element 16 contains a bore 7, which is designed to receive a bolt 8, which is part of a bolt connection. By means of the bolt connection, the cable catching device 20 can be pivotally connected to the rocker support beam.

[0034] The support element 16 also holds the second cable catcher tray 12. The second cable catcher tray 12 contains a second support surface 13, which contains a damping element 14. The damping element 14 is designed in particular according to the damping element 4, which is arranged on the first support surface 3. According to one embodiment, the second cable catcher tray 12 can be displaceably mounted in the support element 16. For this purpose, the support element 16 can have a support element arm 17 extending in a substantially horizontal direction, which in particular contains a guide rail. The support element arm 17 can contain a spring element connected to the second cable catcher tray 12, which in Fig. 2is invisible. The spring element exerts a compressive force on the second rope catch tray 12, so that the second rope catch tray 12 has the maximum possible distance from the first rope catch tray 2. This variant ensures that a derailing rope, which comes to rest outside the first rope catch tray 2 due to vibrations, can be safely absorbed by the second rope catch tray 12.

[0035] The second cable tray 12 can also contain an angled sliding element 18. The angled sliding element 18 serves to guide a support arm, connected to the cable, for a gondola or chair past the second cable tray 12. Before the support arm reaches the second cable tray 12 in the operating state, it touches the angled sliding element 18 on its outer side. The outer side does not run parallel to the direction of travel, but at an angle that can be in the range of 10 to 50 degrees. When the support arm moves along the outer side of the angled sliding element 18 in the direction of travel, a compressive force acts on the angled sliding element, which causes a compression of the spring element and thus a displacement of the angled sliding element 18 and the connected cable tray 12.The support arm can thus slide past the second rope catch tray 12 because the second rope catch tray 12 can perform an evasive movement since it is displaceable on the support element arm 17.

[0036] The rope catching device 20 thus also makes it possible to catch derailing ropes that, due to large vibrations, miss the first rope catching axis 2. Therefore, the rope catching device 20 can be used in particular for applications in which the rope is at a great distance from the rope support roller during the derailment, for example, due to the vibration behavior of the rope.

[0037] As already described in EP 2 792 566 B1, the first and second rope catching shells can each contain an inwardly directed first bend 9 and a second bend 19, so that the first and second rope catching shells, in cooperation with the corresponding first and second support surfaces 3, 13, the corresponding first and second stop walls 11, 21 and the corresponding first and second bend 9, 19, each form a three-point support for the rope 5.

[0038] Fig. 3shows a rope catching device 30 according to a third embodiment, which differs from the previous variants in particular in that the rope normally runs over the underside of the rope support roller and is accordingly received in a downwardly oriented rope catching tray 22 in the event of a derailment. The rope catching device 30 for a cable car thus contains the rope catching tray 22, which has a support surface 23 for a rope 5, wherein the support surface 23 contains a damping element 24. The rope catching device 30 serves to catch and hold the rope 5, which is used as a supporting rope, in the event of a rope derailment. The rope catching device 30 is part of a safety system for the cable car. An existing cable car can be retrofitted with a rope catching device 30.It is also possible to equip an existing cable arrester 30 with a damping element 24 according to one of the embodiments. The cable arrester 30 according to . Fig. 3 is attached to a rocker support beam, on which the cable support rollers (not shown in this figure) are also mounted on a cable support roller rocker. The cable catching device 30 is arranged laterally adjacent to the cable support rollers. The cable catching device 30 contains a support element 26, which is connected to the cable catching tray 22. The support element 26 contains a bore 27, which is designed to receive a bolt 28, which is part of a bolt connection. By means of the bolt connection, the cable catching device 30 can be pivotally connected to the rocker support beam.

[0039] The rope catch tray 22 has an inwardly directed bend 29, so that the rope catch tray 22 together with the support surface 23, the stop wall 31 and the corresponding bend 29 each form a three-point support for the rope 5.

[0040] Fig. 4 shows a view of a safety system 1 containing a rope safety device, in this example a rope safety device 20 according to Fig. 2, and a deflector 40 from above. A cable 5 rests on two cable support rollers 32, which are rotatably mounted in a cable support roller rocker 33. The cable catching device 20 is arranged laterally adjacent to the cable support rollers 32. The cable catching device 20 contains a support element 16, which is connected to the first cable catching tray 2 and the second cable catching tray 12. The support element 16 contains a non-visible bore, which is designed to receive a bolt 8, which is part of a bolt connection. By means of the bolt connection, the cable catching device 20 can be pivotally connected to the rocker support beam 34.

[0041] In Fig. 4A deflector 40 is shown, which is attached to a support arm 35 for a means of transport, for example, a gondola or a chair. According to this exemplary embodiment, the support arm 35 is designed as a hollow body with a square cross-sectional area; of course, the support arm could alternatively be designed as a solid body or with a rectangular or circular cross-sectional area.

[0042] The deflector serves to allow the support arm to move past the cable arrester 20, particularly in the event that the support arm and the means of transport are subject to vibration. A possible vibrational movement of the support arm is indicated by a wave-shaped, dashed line. The vibration has an amplitude corresponding to a deflection of the support arm by 20 degrees, which in Fig. 6 is shown.

[0043] The deflector 40 comprises a fastening element 41 for attachment to the support arm and a deflection element 42. The deflection element 42 is designed as a band element that projects beyond the support arm in the direction of travel and against the direction of travel. The band element has an end region 43 extending in the direction of travel of the support arm and enclosing an angle 44 to the direction of travel that is greater than 0 degrees. According to the present embodiment, the band element also comprises an end region 45 extending counter to the direction of travel of the support arm. The end region 45 encloses an angle 46 to the direction of travel that is greater than 0 degrees. The direction of travel is indicated by an arrow 47.

[0044] Fig. 5 shows a perspective view of a safety system 1 comprising a rope catching device 20 and a deflector 40. In Fig. 5The position of the deflector 40 is shown when the support arm 35 is not subject to vibrations. Only the section of the support arm 35 to which the deflector 40 is attached is shown in order not to overload the illustration. The connecting elements of the support arm with the cable 5 are shown in Fig. 6 The safety system 1 for a cable car according to Fig. 5contains at least one rope catching device 20 and the deflector 40. The rope catching device 20 contains a rope catching tray 2, 12 which has a support surface 3, 13 for a rope 5, wherein the support surface contains a damping element 4, 14. The deflector 40 for the support arm 35 of a means of transport of a cable car for moving the support arm past the rope catching device 20 comprises a fastening element 41 for fastening to the support arm and a deflection element 42. The deflection element is designed as a band element which projects beyond the support arm in the direction of travel and against the direction of travel, wherein the band element has at least one end region 43, 45 which encloses an angle 44, 46 to the direction of travel which is greater than 0 degrees. In particular, the angle 44, 46 is less than 60 degrees.

[0045] Fig. 6shows a view of a safety system 1 comprising a rope catching device 20 and a deflector 40 from the front, ie in the running direction of the rope 5. Fig. 6 schematically shows various scenarios that can occur during a vibration of the support arm 35. The support arm 35 is attached to the cable 5 by means of the fastening device 36, which is not described in detail here. Fig. 6The position of the deflector 40 is shown when the support arm and the gondola or chair attached to it are not subject to any vibrations. This position is designated as the zero position. Furthermore, the deflection positions for vibrations of 5 degrees, 10 degrees, 15 degrees, and 20 degrees are schematically shown. The position of the central region of the deflection element 42 with the length m is shown schematically for each of the deflection positions as a connecting line between the two circular paths indicated by dashed lines, which represent the position of the central region of the deflection element in the various deflection positions.

[0046] When the angle of deflection reaches 5 degrees, the support arm 35 touches the lower rope catch tray 12 of the rope catch device 20. The end area 43 (see Fig. 4) of the module deflector 40 comes into contact with the cable tray 12 and pushes the cable tray 12, which is displaceable in the horizontal support element arm 17, away, so that the support arm 35 can pass the cable catching device 30. If a cable catching device 10 according to Fig. 1a is provided, the second rope catch tray is omitted, so that the support arm 35 cannot come into contact with the upper rope catch tray 3 in the aforementioned angular range. However, the use of a modular deflector for a rope catch device 10 can still be useful, although deflections of more than 20 degrees must be taken into account. If a modular deflector 40 is provided, the support arm 35 can be deflected, preventing the rope from derailing due to contact between the support arm and the rope catch device.

[0047] It is also possible that, if necessary, several module deflectors are arranged one above the other on the support arm 35, so that it can also be ensured that the support arm can slide past the second rope catch tray 12 when the rope 5 is already in the first rope catch tray 2 of a rope catch device 20 and no longer on the rope support roller 32, as in Fig. 6 shown.

[0048] Fig. 7shows a detail of the deflector according to a first exemplary embodiment in a plan view. The deflector 40 for a support arm 35 of a cable car conveyance for moving the support arm 35 past a cable arresting device (not shown here) comprises a fastening element 41 for attachment to the support arm and a deflection element 42. The deflection element 42 is designed as a band element which projects beyond the support arm 35 in the direction of travel and against the direction of travel. The direction of travel is indicated by an arrow 47. The band element comprises a first end region 43 which encloses a first angle 44 to the direction of travel which is greater than 0 degrees, and a second end region 45 which encloses a second angle 46 to the direction of travel which is greater than 0 degrees.

[0049] The band element comprises a plurality of superimposed profile elements 48, 49. In particular, the band element comprises a first profile element 48, which has a greater length than a second profile element 49, wherein the second profile element 49 is designed to rest on the support arm 35. In particular, the second profile element 49 can contain aluminum or be made of aluminum.

[0050] According to the present embodiment, the fastening element 41 comprises two clamping screws 51, 52 for connecting the strap element to a counter-element 53 located on the opposite side of the support arm. The use of this fastening element 41 makes it possible to retrofit a support arm with a deflector 40 designed as a modular deflector. The deflector 40 can be attached to any location on the support arm 35, whereby a cable arresting device according to any of the preceding embodiments can be provided.

[0051] Fig. 8 shows a detail of the deflector according to Fig. 7 in a side view, referring to the description according to Fig. 7 can be referred to. In Fig. 8 It is shown that the clamping screws 51, 52 are accommodated in elongated holes. The deflector 40 is thus adaptable to the corresponding dimensions of the support arm 35.

[0052] Fig. 9shows a detail of the deflector 50 according to a second embodiment in a plan view. The same reference numerals as in the first embodiment have been used for identical or equivalent components. The deflector 50 for a support arm 35 of a means of transport of a cable car for moving the support arm 35 past a cable arresting device (not shown here) comprises a fastening element 41 for attachment to the support arm and a deflection element 42. The deflection element 42 is designed as a band element which projects beyond the support arm 35 in the direction of travel and against the direction of travel. The direction of travel is indicated by an arrow 47. The band element comprises a first end region 43 which encloses a first angle 44 to the direction of travel which is greater than 0 degrees, and a second end region 45 which encloses a second angle 46 to the direction of travel which is greater than 0 degrees.
