Cable brake arrangement

DESCRIPTION

[0001] The present invention relates to a cable arrangement (retention device) for the variable pre-adjustable absorption of kinetic energy in cable constructions, such as elevators, flexible or funicular barriers, according to the preamble of claim 1.

[0002] Such a device is described in DE 10 2005 053 704 A1.

[0003] This cable brake arrangement has two splice points. Between these junction points a cable brake element is provided with a brake plate provided with drills and with several pieces of cable that can be passed against resistance through the drills. The brake plate with the plurality of holes arranged one after the other in several rows is provided with the first splice point at one end. At the second junction point, not oriented towards the first, the pieces of cable are joined together. Each of the cable pieces has been individually passed through a row of the holes arranged one after the other, changing the direction of passage of the cable pieces in the successive holes. The cable pieces are made in the same way and when the cable brake is deployed, all strokes are effective together along the entire braking path.

[0004] Among others, this device has the following drawbacks:

During the braking process, the brake cables of this device are subjected to a very strong mechanical load to bending and shearing, which excludes that the device can be reused.

[0005] In addition, neither the intensity of the braking effect nor the release force can be adjusted freely and independently from each other, but are determined by the construction and dimensioning of the components depending on each other, which in turn leads to greater complexity in commercial use.

[0006] Also, the length of the brake deviation resulting in the braking process corresponds directly proportional to the length of the cable pieces that have been passed, so that the application of the brake, particularly in applications With a great contribution of energy, it leads to a high release force or a large deviation.

[0007] For the rest, in this device the tension prior to applying to the traction branch cannot be seen. An insufficient or excessive tension of the traction branch that is possible for this reason, negatively influences the effective action of the traction branch.

[0008] In addition, the release force of this device is larger than the subsequent continuous braking force, that is, the static friction that must be overcome to release the braking process leads to an unfavorable damping development, which in turn it has the consequence of increasing the costs by the dimensioning of the anchor points.

[0009] Another generic device is known from WO 2009/137951. This known device is made as a device for the damping of cable constructions, in particular for protective constructions against the impact of stones, debris and snow flows and absorbs the energy transmitted to a cable requested by traction, because an intermediate piece defomnable by Tensile forces, which is integrated in a cable applied to traction, have one or more longitudinal elements. Here, the at least one longitudinal element is connected, on the one hand, with one of its ends with a cable end and, on the other hand, is guided around a deflection element connected with the other cable end. Finally, means are provided whereby the formed deviation angle of the longitudinal element (s) is substantially maintained in case of a load of the intermediate piece.

[0010] Among others, this device has the following drawbacks:

The desired braking effect is achieved by plastic deformation of the longitudinal elements, which prevents the brake from being reused.

[0011] In addition, it is difficult to mount this device in series on traction branches, which affects the possibility of using it in the area of special applications.

[0012] Likewise, due to its length, this device requires a greater effort of assembly and manual transport in difficult or wooded terrain.

[0013] In addition, due to its volume and size, this device cannot be mounted in narrow mounting locations or cannot be mounted in an optimal position there.

[0014] Additionally, in this device the intensity of the braking effect and the release force cannot be adjusted freely and independently from one another, but are determined by the construction and dimensioning of the components depending on each other, which in turn leads to greater complexity in commercial use.

[0015] Likewise, the length of the brake deflection resulting in the braking process corresponds directly proportional to the length of the longitudinal elements that have been passed, so that the application of the device, in particular in the case of a great contribution of energy, leads to a high release force or a large deviation.

[0016] For the rest, in this device the previous tension to be applied to the traction branch cannot be seen. An insufficient or excessive tension of the traction branch that is possible for this reason, negatively influences the effective action of the traction branch.

[0017] The object of the present invention is to create a cable brake arrangement of the type indicated in the preamble of claim 1, which can be used in a versatile manner and can be reused in a short time.

[0018] This objective is achieved by the features of claim 1.

[0019] The dependent claims indicate preferable variants of the invention.

[0020] Advantageously, thanks to the invention, a device is created with which in particular

I. It is possible to be able to use the device again in a short time after use.

II. The mode of action is not based on a plastic deformation.

III. The release force can be adjusted variably.

IV. The release force can be adjusted independently of the braking force.

V. The braking force can be adjusted in a variable way.

SAW. The braking force (> release force) can be adjusted independently of the release force.

Vile. Variably adjustable construction and braking force make the “series” assembly of brake devices largely obsolete, without exception for exceptional cases.

VIII. The deviation is, if possible, less than the length of the longitudinal component (s) that have been passed through the device.

IX. The development of the damping shows release or start points as small as possible in the force / time diagram.

X. The type of compact construction favors its manual transport, also in difficult, narrow or wooded terrain.

XI The construction has an indicator, which indicates when the previous tension is reached

desired of the traction branch, without additional measuring devices or auxiliary devices, thus favoring both the effective mode of action of the traction branch and its economic assembly.

[0021] The invention can also be considered an energy absorption device, whose operation is not based on plastic deformation or overcoming static friction but on the transformation of kinetic energy into friction heat, by embracing according to Euyer-Eytelwein, and whose release or braking force can be adjusted independently of each other and variable in situ, in addition to being indicated with it when the desired pre-tension of the traction branch is reached.

[0022] The device according to the invention preferably comprises two main components that fit into each other, a boiar frame and the embrace component (s), which are connected respectively with one of two anchor points in at least one branch (cable) tensioned.

[0023] The brake device is activated by the increase in tensile forces, exceeding the kinetic energy that acts in the first place on the preset release force of the brake device, thereby tensing the clamped component with strong tension around the bollard. When the preset braking force is then reached, the hugging unit slides in a controlled manner around the boiardo frame boiardo. By the resulting friction, kinetic energy is converted into thermal energy.

[0024] The first, second and / or third clamping device of the cable brake arrangement according to the invention may comprise simple arrangements or multiple arrangements. Such arrangements have to be understood, for example, as clamps adapted to the shape of the embracing arrangement, which are tightened by means of threaded areas that can be passed at the ends through the frame by means of suitable screws, in order to be able to hold the hugging arrangement in the corresponding areas.

[0025] The hugging arrangement can be made in particular as a cable arrangement, so that in this case the clamping devices can be cable clips, in which one, two or several such clips can be provided by clamping device, according to the forces to be absorbed.

[0026] The free end zones of the hugging arrangement or the cable arrangement are preferably provided with stop pieces, so that these free end zones can be prevented from being removed from the frame when forces are applied to the cables, in which the cable brake arrangement is arranged.

[0027] In one of the free end zones an indicator zone of another color may be visible, which changes its position upon reaching the traction branch the desired pre-tension.

[0028] As already explained at the beginning, the cable brake arrangement according to the invention can be provided in devices comprising cable constructions. Devices of this type can be elevators, flexible barriers, funicular or also retention fences, as in particular protective constructions against the impact of stones. An example for a protective construction against the impact of stones is described in EP 2 489 785 Al, whose disclosed content is converted by remission into the content disclosed by the present application. A protective construction against the impact of stones of this type generally comprises a plurality of supports arranged, for example, on a hillside, which are anchored in the subsoil and which tend for example by means of upper, central and / or lower cables, which they are guided in the supports, a net, with which objects can be retained, such as stones or trees. The cables used to lay the network can be provided with one or several cable brake arrangements according to the invention, which can be arranged for example in the area of the network or in the area of rock anchors, which can be fixed in the subsoil to tension the cables.

[0029] Other details, features and advantages of the present invention result from the description set forth below of some embodiments using the drawing. They show:

FIGURE 3 a top plan view of the cable brake arrangement according to FIGURE 2 and

FIGURE 4 a sectional view of the cable brake arrangement according to FIGURE 3 along the line A-A in FIGURE 3.

[0030] The structure of the cable brake arrangement 1 according to the invention results from a joint view of FIGURES 1 to 4. FIGURE 1 shows an embodiment of the cable brake arrangement 1, which has a first, second and third clamping device 13, 15 or 18, which in this embodiment is made as a simple clamping device.

[0031] In contrast, FIGURES 2 to 4 show an embodiment in which said fasteners 14, 15, and 18, which will be described in detail below, are made as double arrangements. As explained at the beginning, in principle it would also be possible to provide several fasteners per fastening device, there being no differences between the embodiment according to FIGURE 1 and those according to FIGURES 2 to 4 with respect to the base structure, so that the structure and operation of the cable brake arrangement according to the invention will now be described, taking into account all the graphic representations in FIGURES 1 to 4.

[0032] Accordingly, the cable brake arrangement 1 according to the invention has a frame 2, which has a first cable splice element 3 with a first end frame area 4. As the FIGURES show, this splicing element of Cable 3 is made as a known cable shackle, which in the case of the example is fixed by a hole in a connecting plate 2C of the frame 2. On the side of the frame 2 opposite the first end area of frame 4, a second end frame area 12 is provided, in which area a second cable splice element 10 is arranged, which is also made as a cable shackle. The two cable splice elements 3 and 10 serve to mount the cable brake arrangement 1 in one of the arrangements explained at the beginning, which has one or more cables, which must be braked or dampened during braking by means of the provision of cable brake 1 according to the invention.

[0033] The cable brake arrangement 1 also has a cylinder 5, also called a boot, which is fixed in the frame 2. In the embodiment shown in the FIGURES, this frame has two side plates 2A and 2B arranged for this purpose. one parallel to the other and spaced apart from each other, which are joined by a total of four connecting elements 2C to 2F that extend in the transverse direction. Here, the connecting element 2C is realized as the joining plate already explained above, which can be joined in its final zones by welding with the side plates 2A and 2B.

[0034] The other connecting elements that extend in the transverse direction are three 2D, 2E and 2F joint bolts, the 2D joint bolt being arranged in the final area 4 of the frame 2, for example, below the plate of union 2C.

[0035] The other two connecting bolts 2E and 2F are arranged in the opposite end zone 12, also one above the other and spaced apart from each other. The 2D to 2F joint bolts can also be welded together with the two side plates 2A and 2B. In principle, other joining devices are also imaginable, such as bolted joints.

[0036] The brake arrangement also has an embrace arrangement, which is designated in conjunction with the reference sign 6. In the case of the example, the embrace arrangement 6 is a cable arrangement, which has a first end zone 7 free and a second end zone 8 fixed on the frame 2, as well as an embrace zone 9 disposed between these end zones 7 and 8. The embrace zone 9 has in the embodiment 4 represented in the embraced FIGURES that pass around the bollard 5, which before resting a force either rests only loosely on the bollard, as can be seen in particular in FIGURES 1 and 2, or is arranged even at a certain distance from bollard 5, and this distance can be chosen, so that when applied

a cable force to the cable brake arrangement 1 does not have to overcome static friction between the clamps 9A to 9D and the bollard 5.

[0037] The arrangement in bollard 5, whose surface may preferably be provided with a coating that increases friction, and the cuddles 9A to 9D is a damping device, which reduces energy by friction and the heat generated in this way, as already It has been explained at the beginning.

[0038] The cable brake arrangement 1 also presents, as explained above, a first fastening device 13, which is arranged in the frame 2, adjacent to the second end frame area 12. This first clamping device 13 holds a first clamping zone 14 of the clamp arrangement 6 in the frame by means of an adjustable force, which represents a release nut, which prevents a transmission of force to the clamp arrangement until it is overcome by the forces of the construction cables in which the cable brake arrangement 1 is integrated.

[0039] As shown in FIGS. 1 and 2, the first fastening zone 14 of the clamp arrangement 6 is disposed adjacent to the second end frame area 12 and is further disposed between a joint zone 11 of the arrangement of embracing 6 and bollard 5, the junction zone 11 being folded preferably in a semicircular manner in the embodiment shown in FIGURES 1 and 2, which is especially preferable, and extending from an end zone 8 fixed on the arched frame to the holding area 14, as seen in the graphic representation of FIGURES 1 and 2.

[0040] The cable brake arrangement 1 further presents a second clamping device 15, which fixes a second clamping zone 16 of the free end zone 7 adjacent to the first end frame area 4 of the frame 2 by an adjustable force in the same, this adjustable force representing the braking force of the cable brake arrangement 1 according to the invention.

[0041] In addition, a third clamping device 18 is provided, which fixes the second end zone 8 of the clamp arrangement 6 by an adjustable force on the frame 4, this adjustable force representing the pre-tension of the traction branch, which allows that the indicator field 22 changes its position upon reaching the desired pre-tension of the traction branch.

[0042] As FIGS. 1 and 2 show, the first free end zone 7 and the second final zone 8 of the clamp arrangement 6 are provided respectively with a stop piece 19 or 17, which prevent the corresponding end zones from passing through the clamping device 15 or 18.

[0043] As can be seen in particular when FIGS. 1, 2 and 4 are seen together, the joining area 11 of the clamping arrangement 6 is guided by a guide element 20 preferably made in a circular manner, which has a guide groove. 21 preferably also circular, in which the joining area 11 fits, as can be seen above all in the representation of FIGURE 4.

[0044] The invention is, therefore, an energy absorption device based on the transformation of kinetic energy into friction heat, which, held between two anchor points, acts on at least one tensioned (cable) branch.

[0045] It preferably comprises two main functional elements: on the one hand, the bollard frame 2, which acts as a support for components and, on the other hand, the hugging unit 6, by which the kinetic energy that acts on the bollard 5 and is transformed by friction into thermal energy. Each of the two main functional elements is connected by respectively only one anchor point directly to the traction branch.

[0046] The bollard frame 2 may have one or more panels or sheets made of suitable materials, in which both the individual components of the clamping unit 6, that is, the bollard 5, the adjusting device 13 of the releasing force, the adjusting device 15 separated from the braking force, the pre-tension indicator 22, as well as the joining area 11, which can be realized as single or multiple suspension. With one end 2C, the bollard frame 2 is directly connected with the traction branch and with the clamping unit 6 it is only indirectly connected with the traction branch.

[0047] The clamping unit 6 may have one or more cables or other suitable flexible components, which may be made as tape, wire or strands, and which are passed through the bollard frame 2.

[0048] The embracing unit 6 can be connected to one end directly (ie 1: 1) or by multiple suspension (ie 2: 1 or more) with the traction branch. From there, the hugging unit passes through the clamping device 13, whereby the release force of the retention device can be preset in a variable manner. After passing through the clamping device 13, the hugging unit 6 passes once or several times around the bollard 5, where the kinetic energy that acts is transformed by friction into thermal energy. Following the bollard's embrace, the embrace element enters the other clamping device 15, with the aid of which the absorption energy of! Can be preset without stepping! retention device / cable brake arrangement. The embracing element now ends in an exit section 7 which can be freely chosen, at which end the stop 19 is fixed, to prevent an exit of the embracing element from the bollard frame 2.

[0049] In addition to the object of the invention described above in writing, reference to the graphic representation of the invention in FIGURES 1 to 4 is explicitly made to complete the content disclosed in the present application.

[0050] Here, it should be noted that in addition to the embodiment of the frame 2 shown in FIGURES 1 to 4 as a three-dimensional shape of the side plates 2A and 2B with the joining elements 2C to 2F, the frame 2 can also be made as a flat plate, which has a preferably central recess, in which bollard 5 can be arranged and also fixed at the ends. All the components described above can also be fixed in such a flat plate frame.
