[0001]
BACKGROUND OF THE INVENTION
The present invention, pivotally a first Tightening jaws are rigidly secured to the other end of Tightening body with a line roller run on one end, to said first Tightening jaws or Bei example was Installing tighten device and a second tightening jaws attached to Rannahli is formed in a first end of the second tightening jaws clamping lever, the other of said clamping lever At the end, the braking control rollers constituting the that control elements to effect provided we are in our rails and cross, said clamping lever by the control roller, anti the effect of bets Shonbane attached to said tightening body and it has a pivotable relative body, in the case of its, the clamping lever is held in one position beyond the two dead centers by the torsion spring, the cabin or in the conveying or traction cable of the cableway system Device for connecting conveying means such as a chair About.
[0002]
[Prior art]
A coupling device of this type is known from the European patent EP621163B1. In the case of this known device, two clamping levers with arms are provided, a control roller is attached to one end of the lever, and a second clamping jaw is arranged at the other end. There is also provided a spring energy accumulator that interacts with the clamping lever via a toggle lever joint. The clamping lever is pivoted by the control roller, and the line connecting the pivoting lever pivot and the pin connecting the toggle lever joint on the clamping lever is related to one of the two levers of the toggle lever joint and the dead center of the clamping lever Define the position. In a first position different from the dead center position, the clamping lever is pivoted and held in this position by the spring energy store in the open position of the second clamping jaw and in a second position of the clamping lever different from the dead center position. The clamping lever is pivoted and held in this position by the spring energy accumulator in the closed position of the second clamping jaw. Control roller induced pivoting of the clamping lever from one of these two positions is caused in the first part of the pivoting movement against the action of the spring energy store.
[0003]
This known coupling device is very inconvenient because the clamping lever and thus the pivotable clamping jaws arranged on it are always arranged in a defined position. As soon as the conveying means is connected to the conveying or towing cable, the control roller travels on the control rail, so that the clamping lever moves from the open position of the second clamping jaw to the closed position of the second clamping jaw. Is pivoted and as a result is held in this position by the splash energy store. As soon as the conveying means is decoupled from the conveying or towing cable, the control roller pivots the clamping lever past the dead center position against the action of the spring energy accumulator, resulting in the second clamping jaw. The part changes to an open position where the jaws are likewise held by a spring energy store.
[0004]
This requires only a control rail to pivot the clamping lever from the first position to the second position and again from this second position to the first position, so a very simple design of the cableway device To achieve. Furthermore, this reduces the number of pivoting lever pivoting movements by half in relation to the prior art.
[0005]
However, this known coupling device is subject to operating conditions in which the cableway device may exert a rotational movement with respect to the conveying or towing cable about an axis that is approximately vertically aligned with the conveying means relative to the cable. If you get the condition is not satisfied. You are noted here for the fact that the length of the pivotable clamping jaws extending along the transport or traction cable is approximately 5 times the diameter of the cable. As a result, in the case of such a rotational movement of the conveying means with respect to the conveying or towing cable, such a large torque will cause the two clamping jaws to die from the closed position of the clamping jaw where the clamping lever can pivot. Pivotable clamping jaws and fixings that are moved away from each other against the action of the spring energy storage to the extent that they can be pivoted to the open position of the pivotable clamping jaws via the point position It can occur between the ends of the clamping jaws as seen in the longitudinal direction of the cable, away from each other. The clamping lever is then held in this position by the spring energy store, so that the conveying means is consequently disconnected from the conveying or traction cable without control by the control roller.
[0006]
[Problems to be Solved by the Invention]
On the other hand, such a condition may occur in the case of very strong winds when the cableway device is operating, which is dangerous for the passengers because the transport means can be disconnected from the cable. On the other hand, such operating conditions may also occur in the case of very strong winds when the cableway device is not in operation, in which case the conveying means can likewise be disconnected from the cable. Although not accompanied by passengers at risk in this case, the interruption of the function results in the associated transport means having to be reconnected to the cable at the correct distance from the transport means as soon as the cableway device is turned on again. It is generated because it must not. Such rotational movement of the conveying means, in which the clamping devices can be pivoted to their open position, also causes significant lateral oscillation of the conveying means when the conveying means collides with the support or with other conveying means. May occur in the case of
[0007]
It is therefore an object of the present invention to provide such a coupling device so that unintentional pivoting of the pivotable clamping jaw to its open position can be reliably avoided even in the case of very unfavorable operating conditions. Is to improve.
[0008]
[Means for Solving the Problems]
According to the present invention, at least one of the two clamping jaws has at least one stop surface disposed opposite to the clamping surface of the jaw with the cable interposed therebetween, on both sides of the other jaw. the cable along with Bei Eteori, element, the said clamping body, when rotated about an axis intersecting the cable, wherein a stop surface are made possible receiving the cable, further, the a stop surface, the pivotable second fastening jaws clamping surfaces of the achieved by Rukoto are disposed on the opposite side across the cable.
[0009]
Kururudoka ability clamping jaws, the configuration includes a a stop surface disposed opposite the Tightening face across the cable, on opposite sides of the fixed clamping jaw, the longitudinal direction of the clamping jaws as seen in the previous Kikururudo available-clamping jaws, said to form a a stop surface for the cable in each case has at least one extension.
[0010]
According to an alternative embodiment, the tightly clamped clamping jaws are provided with a stopper surface which is arranged relative to the clamping surface in relation to the cable. In this case, on both sides of the front Kikururudo available-clamping jaws, the clamping as seen in the longitudinal direction of the jaws, the rigidly fixed clamping jaw, forms a a stop surface in each case At least one extension.
[0011]
One of the clamping jaws is preferably provided with at least one substantially semicircular recess directed towards the reception of the cable, the diameter of which is somewhat larger than the diameter of the cable and extends over 180 °, A surface and the at least one stop surface are formed by the inner surface of the recess. In this case, the recess can extend over an angle of approximately 200 °, and the inner width of the recess can be approximately 20% larger than the diameter of the cable.
[0012]
According to another preferred embodiment, the sum of the one stop surface of the clamping jaw and the clamping surface of the other clamping jaw is equal to the length of the clamping surface of the one clamping jaw.
[0013]
The coupling device according to the invention will be described in more detail below with reference to two exemplary embodiments shown in the drawings.
[0014]
The connecting device shown in FIGS. 1 to 4 includes a clamping body 1 to which a rod 11 for supporting conveying means such as a cabin or a chair is fixed. Further, Attached to the clamping body 1 is a running rollers 12 and 13 thereby clamping body 1 is guided along the rails 12a and 13a of the stop stations of the cableway system. Clamping body 1 is provided with a clamping device having a rigidly fixed clamping jaw 15 and pivot available-clamping jaws 25.
[0015]
The clamping device 2 is also fixed to the clamping body 1 in the same way and includes a spring energy accumulator in the form of a torsion spring 3 to which the first lever 21 is fixed, the second lever 22 being free of the first lever. It is continuous contact via a bearing 21a on the end. The other end of the second lever 22 is mounted in the bearing 22a of the clamping lever 23, which is attached to the clamping device 2 in the bearing 23a with respect to its first part. The two levers 21 and 22 form a toggle lever joint that acts between the torsion spring 3 and the clamping lever 23.
[0016]
In the left side of the drawing, the clamping jaws 25 pivotable second fastening the pivoting of Tightening lever 23 caused by the ends are guided to the control roller 24 is positioned to the right of the drawing lever 23 Is formed . The other end of the clamping lever 23 is provided with a to that control roller 24 travels on the control rail 24a in the stop stations of the cableway system, and as a result the clamping lever 23, clamping jaws 25 are twisted release of the torsion spring 3 is pivotally moving toward the open position is maintained to the original no-load state is.
[0017]
In Figure 1, the jaws 25 tighten pivotable is placed in its closed position, shows a state of being connected to the cable 5 with the body 1 tightening clamping device 2 by the. In this case, the toggle bearing 2 1a is a connecting point of the first lever 21 and second lever 22 constituting the lever joint hand, the clamping lever 23 on the body 1 and tightening preparative Shonbane 3 bearings 23a and clamping placed between bearings 22 a which connects the second lever 2 2 on the lever 23. Since the first lever 21 forming a toggle lever joint hand it is pivoted in the direction of arrow D by the torsion spring 3, which is a bearing 23a clamping lever 23 is forced in the direction of arrow E becomes a pivot point. As a result, the pivotable clamping jaw 25 is changed to the closed position and held in this position. The closing force required for this is applied by the torsion spring 3.
[0018]
As soon as the coupling device enters the stop station of the cableway device, the running rollers 12 and 13 roll along the rails 12a and 13a, and the control roller 24 runs on the control rail 24a, so that the clamping lever 23 is It is pivoted against the action of the torsion spring 3 against the direction of arrow E toward the open position of the pivotable clamping jaw 25. This pivoting of the clamping lever 23 changes the clamping lever beyond the dead center position to the open position of the clamping jaw 25 held by the torsion spring 3. In this case, the control roller 24 travels along the control rail 24b.
[0019]
Figure 2 further shows one of the acceleration and deceleration gear 6 interacts with the friction plate 9 provided in the main body 1 fastening and arranged in the stop station. As a result, in the stop stations, resulting in a decrease of the speed of the transport means to be uncoupled from the cable 5, as a result passengers ride down or vegetables kana filled or it therein from the conveying means, and / or transport means Is increased to such a range that the conveying means can be connected to the cable 5 again.
[0020]
Can be seen from Figure 3 is that the clamping lever 23 and pivoted available-clamping jaws 25 is formed of a forked design, FIG. 3 is measured in the direction of conveying or traction cable 5 as such, the length of Kururudoka ability clamping jaws 25 is a case which is at least approximately five times the diameter of the cable 5.
[0021]
As can be seen from FIG. 4, Kururudoka ability clamping jaws 25, one side, when the clamping body 1 are aligned in a straight line parallel to the cable 5, the cable 5 over its entire length And a clamping surface 26 for supporting. Further, laterally outwardly of the fixed clamping jaw 15, Kururudoka ability clamping jaws 25, two a stop surface 28 on the side which is located opposite the clamping surface 26 across the cable 5 is formed 2 Two extension portions 27 are provided. Therefore, Kururudoka ability clamping jaws 25 is provided with a recess two substantially semicircular its diameter extends over an angle of somewhat larger and approximately 200 ° than the diameter of the cable 5. The inner width of the recess is approximately 20% larger than the diameter of the cable 5.
[0022]
The effect of Kururudoka ability clamping jaws 25 with reference to FIGS. 5 and 6 will be described below. For example, as a result that was fueled by strong winds, the conveying hand stage is connected to the transfer or traction cable 5, about an axis intersecting the cable 5, that is, the cable 5 in the direction of arrow G in FIG. 6 if it is rotated against, as shown in FIG. 5, which assume a position having an angle to the cable 5 the clamping surface 16 of the clamping jaws 15 the body 1 fastening. As a result, a part of the cable 5 is supported on one end of the region 16a of the clamping surface 16 , while the other part of the cable 5 is in the region 26a of the clamping surface 26 of the pivotable clamping jaw 25 . at the other end at a distance in the axial direction from the one end described above, Hatarakashi force F1 facing the closing force of the spring energy storing member 3, so that the to pivot available-clamping jaws 25 is contrary to the direction of the arrow E (see FIG. 4), is pivoted toward its open position. In this case, if the top dead center position of the tightening lever 23 is exceeded, Kururudoka ability clamping jaws 25, its position is held by a spring energy storing member 3, it biased to its open position.
[0023]
To prevent pivoting to this open position, Kururudoka ability clamping jaws 25 clamping surfaces 26 and scan Totsupa surface 2 8 on both sides of the opposing position of the other clamping jaw 15 across the cable 5 two extension portions 27 are provided that are shaped forming a. When and the cable 5 tightening only jaw 15 is aligned parallel to each other, wherein a stop surface 28 is placed at a certain distance from the cable 5. However, tightening the body 1 is rotated around the axis intersecting the extending direction of the cable 5, so that the pivot available-clamping jaws 25 are pivoted to the bearing 23a as a fulcrum, the scan Totsupa surface 28 of the clamping jaws 25 comes to supporting lifting the side of the cable 5. As a result, while the cable 5 the jaws 25 tighten a Kururudoka ability, through the region 26a of the clamping surface 26, a force acting in the direction of the open position of the jaws 25 tighten a Kururudoka ability F1 Work. On the other hand, the cable 5, the Kururudoka ability clamping jaws 25, via the opposite a stop surface 28 at an angle equal consist magnitude and tightening Hatarakashi a force F2 acting in the opposite direction the jaws 25 to prevent the is the Ranaru pivot.
[0024]
This is also in the case of not appropriate operating conditions of the cableway system, Kururudoka ability clamping jaws 25 is exerted on the pivoted available-clamping jaws 25 by the cable 5 and in the opposite direction it means that makes it impossible to exceed the dead point position of the force clamping lever 23 which acts, always held in the closed position of the pivotable clamping jaw 25 Waso becomes Rukoto.
[0025]
FIGS. 7 to 21 show possible positions that the clamping device can take with respect to the transport and traction cable 5 in its closed position.
[0026]
7, 8 and 9 show the two clamping jaws 15 and 25 of the clamping device being aligned parallel to the cable 5. In this case, the Tightening face 2 6, are supported entirely tight contact other a Tightening face 16 Togake Buru 5 from both sides. Conversely, a stop surface 28 of extension 27 of Kururudoka ability clamping jaws 25 is placed a slight distance from the cable 5.
[0027]
10, 11, 12 and 13 show a first rotational position of the two Tightening jaws 15 and 25 with respect to the cable 5. In this case, the cable 5 is supported against the clamping surface 26 of the jaw 25 pivoted available-tightening Te other end odor and clamping jaws in the region 26a, the cable 5 the jaws 15 clamped in the region 16a An adjacent stopper surface 28 that supports the clamping surface 16 and is very close to the cable 5.
[0028]
14, 15, 16 and 17 show the position taken for the cable 5 when the clamping body is further rotated. In this case, the cable 5 becomes supported against one of the two stop surfaces 28, which prevents the clamping lever 23 from pivoting further.
[0029]
18, 19, 20 and 21 further show that this rotation is transmitted to the conveying or traction cable 5 when the clamping body 1 is further rotated.
[0030]
22, 23, 24 and 25 show alternative embodiments of the coupling device according to the invention. In this case, fastening is firmly fixed to the body and Tightening jaws 15a designed fork shape, the inner surface of its the feeding transportable two extension portions 17 which acts as a stop surface 18 of the cable 5 or the support sandwiching the cable 5 is provided in opposition side. Conversely, the second clamping jaws 25a of Kururudoka ability is arranged so as to be sandwiched along the rigidly fixed clamping cable extension 17 of the jaw 15a. In this case, rigidly fixed clamping jaw 15a is designed in the same manner as described with respect Kururudoka ability clamping jaws with reference to FIG.
[0031]
As can be seen from FIG. 22, the cable 5 is arranged at a distance from the stopper surface 18 of the clamping jaw 15a which is firmly fixed, unless the conveying means and thus the clamping body is rotated relative to the cable 5. The However, as soon as the tightening body is rotated relative to the cable 5 about an axis intersecting with respect to the cable 5, Kururudoka ability clamping jaws 25a, to the one cable 5 of a stop surface 18 It is pivoted in the direction of its open position until it comes to support, so that the clamping jaw 25a cannot be pivoted further. This likewise prevents the pivoting of the clamping jaw 25a to its open position reliably.
[0032]
Therefore, it is only triggered by a control roller which operation of the clamping lever pivots from the closed position of Kururudoka ability clamping jaws rolls along the control rail, effect required reliability of the resulting connecting device A coupling device is provided which ensures that the performance is guaranteed at any given operating condition.
[0033]
Instead of the torsion springs, it is also possible and applicable child some other spring structure Zotai as the spring energy storage member.
[0034]
