Definitions

the invention relates to an alternating load roller battery for guiding conveyor ropes in cable cars, in particular in single cable orbits, with a frame which can optionally be rotated about a pivot, on each of which at least one rocker arm which can be pivoted against spring force and carries at least one roller is arranged below and above the conveyor cable .
the support roller rockers or rockers are adjustable relative to the pressure roller rockers or rockers, but are firmly clamped during operation. An overload of these fixed tensioned roller batteries is possible.
both the support rollers and the pressure rollers or the rockers to which these rollers are attached are pivotally mounted against a spring force, the spring elements each bracing a support rocker with a pressure rocker with spring force.
the pressure rollers and the idler rollers are always tensioned with the same spring force at each hoisting rope load, which must be assumed to be relatively high in order to maintain the required minimum roller load with each hoisting rope load. So that press the pressure rollers even with a perfect load with a no longer necessary, very high counterforce on the conveyor cable, so that when driving the driving equipment or clamp a correspondingly high roller impact occurs and the wear on the conveyor cable and the rollers is unnecessarily increased.
roller batteries In addition to these alternating load roller batteries, which can absorb both positive and negative rope loads, roller batteries have been used, the approx derte lower support rollers and spring-loaded overhead pressure rollers.
the spring-loaded pressure rollers serve as safety rollers, which, in the event of load changes that always take place in the positive rope load range, ensure that the minimum roller load is given on the support rollers.
roller batteries are not suitable in practice as alternating load roller batteries, and are also not used as such, since the high contact pressure of the pressure rollers (high spring preload) required to absorb negative cable loads results in an uncomfortably high roller impact, which also occurs with sufficient contact pressure of the conveyor rope on the idlers does not decrease.
the object of the invention is to eliminate these disadvantages and to provide an alternating load roller battery, in which an overloading or underloading of the rollers by the conveyor cable is avoided under load balancing.
the carrying rollers of the alternating load roller battery according to the invention When the carrying rollers of the alternating load roller battery according to the invention are loaded by the conveyor cable, they move downward against the force of one or more spring elements.
the pressure rollers pressing from above onto the conveyor cable go down with the loaded conveyor cable, one or more spring elements of the pressure rollers relaxing from the spring element of the support rollers relaxing. If the load capacity is an and there is a minimum roller load on the support rollers that is prescribed or necessary for the cable car, the pressure rollers will only press on them with much reduced force Conveyor rope, which reduces the roller impact and reduces wear on the rope and rollers. According to the regulations currently in force in Austria, the pressure rollers must still be in contact with the conveyor cable even if the idlers are sufficiently loaded.
the weight of the pressure rollers and their suspension is sufficient, for example.
a force exerted by the spring elements assigned to the pressure rollers can also act.
the lower idler rollers only push the conveyor cable to a much reduced extent due to the geometric position.
the carrying rollers exert more and more pressure on the conveyor cable due to the changed geometric position and thus ensure the required load on the pressure rollers.
a preferred embodiment of the alternating load roller battery according to the invention with good rope guiding properties consists in the fact that two support roller rockers, preferably symmetrical to a normal plane perpendicular to the conveyor rope, and two pressure roller rockers, preferably symmetrical to this normal plane, are provided on the rockers known rocker-bearing rockers are pivotally mounted.
the position of the pivot axes of the support roller rockers and / or the pressure roller rockers relative to the frame of the roller battery can be adjusted perpendicularly to the conveyor cable.
a structurally simple solution consists in that for a pair of idler rocker arms or a pair of pressure roller rockers a spring element which acts only on the idler roller rockers or pressure roller rockers itself and is preferably designed as a compression spring is provided. This means, for example, that only one pressure element is required for two idlers and two pressure rollers.
spring elements arranged in this way which do not act on the frame, there is a simpler adjustment of the spring preload of all spring elements, only the position of the pivot axis of the rockers on one side of the conveyor cable, for example on the pressure roller side, having to be adjustable.
a preferred feature of the invention provides that the spring travel of the spring element (s) of the idler arm (s) is limited by stops which can be set, if necessary.
the spring elements are then, for example, prestressed to such an extent that compression (in the case of compression spring elements) of the spring element on one side of the conveyor cable up to the stop still produces the prescribed minimum contact pressure on the other side of the conveyor cable.
a preferred embodiment of the roller battery according to the invention which is particularly resistant to mechanical damage and weather influences, consists in that at least one spring element has a compression spring element arranged in telescopically displaceable cans, it being particularly favorable for long operation and for centering the spring element if a sliding insert made of well sliding, resistant material, for example polytetrafluoroethylene, is arranged between the mutually moving walls of the cans.
compression spring elements are bodies made of soft elastic foam, which deform elastically even under high loads.
the cans surrounding such a compression spring element also protect it from UV rays contained in sunlight, particularly in glacier regions.
FIG. 1 schematically shows a side view of an alternating load roller battery according to the invention without being loaded by the conveyor cable
FIGS. 2, 3 and 4 each schematically show a further exemplary embodiment in three different load states
FIG. 5 shows an exemplary embodiment of a compression spring element in a sectional view.
the frame 1 is the change load roller battery mounted on a adjustable on a support or a station building roller battery suspension (not shown) rotatable about a pivot 2.
the frame has 3 swivel axis holders 1 a and 1 b below and above the conveyor cable, of which the upper 1 b is adjustable in a direction perpendicular to the conveyor cable 3.
the upper swivel axis holder 1b carries two swivel castor arms 5 which can be swiveled about swivel axes 4 and to which two swivel castors 7 which are in contact with the conveyor cable 3 are fastened via rotatably mounted rockers 6.
the supporting roller side is constructed analogously.
the spring element 13, which is independent of the spring element 8, causes the two support roller rockers 10 mounted in pivot axes 9 and the rockers 11 to exert an upward force on the four support rollers 12.
the independent spring elements 8, 13 each consist of two cans 8a, 8b or 13a, 13b, which can be telescopically displaced relative to one another, in each of which a compression spring element 14 or 15 made of flexible foam is arranged, which, in addition to good elastic properties, also has good damping properties.
a layer, not shown, of resistant, well-sliding material is arranged between the can walls which are moved against one another.
the compression spring element 14 shown in FIG. 5 consists of a rotationally symmetrical foam body 14a, which surrounds a cavity 14b. Approximately in the middle, it has an annular groove 14c. To fasten the compression spring element 14 in one of the cans 13a or 13b, a sheet 14d embedded in the foam and a nut 14e lying thereon are provided.
An additional load on the pressure rollers 7 can also be exerted by the spring element 8 in the position shown in FIG. 2.
the pressure exerted by the pressure rollers 7 on the conveyor cable 3 is due to the changed geometric position of the rollers in this load case (sufficient load load) much lower than in the load case (Fig. 2), where the support rollers 12 are not sufficiently loaded and the pressure rollers 7 have to ensure an adequate load.
the pressure rollers 7 move upward from the position shown in FIG. 2 (FIG. 4). As a result of this upward displacement, the spring element 13 relaxes and the support rollers 12 exert a substantially lower to no pressure on the conveyor cable 3. This is not necessary if the pressure rollers 7 are sufficiently loaded. However, if the load on the pressure rollers 7 is reduced by the conveyor cable 3, the pressure of the support rollers 12 increases upwards and an adequate load on the pressure rollers 7 is ensured.
the spring elements can also act between the rocker and the frame.
the number of roles is not limited to eight.
compression springs such as helical springs
tension springs are also suitable as spring elements.
additional damping elements can be provided.
the alternating load roller battery according to the invention can advantageously be used in single cable orbits, such as drag lifts or chair lifts, wherever the rope load forces act more or less downwards or upwards when the hoisting rope changes.
