Definitions

  • the present invention relates to an elevator, a method for maintaining the Elevator, a method for modernizing an elevator and a tensioning device for an elevator according to the definition of the independent claims.
  • US-4620615 discloses a traction sheave elevator in which to increase the Coefficient of friction between traction sheave and rope, the rope over a special Clamping device is pressed against the traction sheave.
  • the jig has a variety of roles that are held in a frame and what roles are made of polyurethane and the rope with a high coefficient of friction and in a wrap angle press against the traction sheave.
  • the object of the present invention is to provide an elevator which is simple and is inexpensive to purchase and maintain.
  • An existing elevator is also said to be can be modernized easily and quickly with components of this elevator.
  • the elevator in a building with storeys I, II, III, IV, V and a shaft 9 advantageously has the components suspension or propellant 1 , power transmission means 2, guides 10, drive 5 , car 7 , counterweight 8 , Support body 3, brakes 5 ', 40, 7', tensioning means 4, 4 ', 4 " on.
  • the disposition and size relationships of the components of the elevator according to FIG. 1 are exemplary and not binding for the design of the invention. It is therefore entirely possible not to place the drive in the shaft, but in a separate machine room, and it is also possible to use an elevator without a shaft floor or without a shaft head, so that the shaft does not protrude above the bottom plate of the lowest floor or the ceiling of the top floor.
  • the force transmission means rests with a drive surface 20 on the suspension or propellant.
  • the force transmission means rests with a drive surface 20 ' on the support body and / or on the tensioning means.
  • the drive optionally has at least one auxiliary pulley 6 .
  • the drive, the support body, the rotating body-like clamping means and the auxiliary pulley can advantageously be rotated in two opposite directions of rotation (see curved double arrows).
  • Suspension or propellant For the purposes of the present invention, any known and proven suspension or propellant can be used for elevators. A combined suspension or propellant is advantageously provided for supporting the operating weight and for moving the cabin and an optional counterweight. In principle, the functions of suspension and propellant can also be separated. Thus, with knowledge of the invention, it is possible to provide a carrying means for carrying the operating weight and, independently of this, to provide a propellant for moving the cabin, only the propellant being moved by the power transmission means. For example. The cabin and counterweight hang on a rope as a suspension element and are moved by a lower rope as a propellant.
  • the carrying and propellant is advantageously a rope, a double rope and / or a belt such as a flat belt, toothed belt, V-ribbed belt, etc.
  • the toothed belt can have teeth on one or both of its sides.
  • Diverse materials such as metal and / or natural material and / or plastic can be used. Steel, steel alloys, etc. may be mentioned as metal, leather, impregnated leather, rubber, etc. as natural material, aramid, nylon, polyurethane, carbon fiber, zylon, etc. may be mentioned as plastic
  • the load-bearing or propellant can have layers of steel, steel alloys, aramid, carbon fiber, zylon, etc. that absorb tensile forces.
  • the suspension or propellant preferably has closed ends which form a loop.
  • the suspension or propellant preferably has open ends and is connected to the cabin and the counterweight.
  • Friction coefficient are in direct contact with each other Components of power transmission means, suspension or propellant, tensioning means and Support body optimized friction values.
  • the contact surfaces of these components consist of metal such as steel, Steel alloys, aluminum, aluminum alloys, etc. and / or natural material such as Leather, leather impregnation, rubber, etc. and / or plastic such as polyurethane, Nylon, carbon fiber, etc.
  • the drive is advantageously a gearless linear drive.
  • the drive is advantageously of elongated cylindrical shape or a flat external rotor. With knowledge of the present invention, the person skilled in the art has many possibilities for varying drives.
  • wrap angle These high coefficients of friction have a high traction effect, which in turn only requires a relatively small wrap angle.
  • the drive and the carrying or driving means are translated to each other, ie a drive shaft rotates faster about its axis of rotation than the carrying or driving means moves with the support body.
  • This translation follows from the size ratio of the diameter of the support body to the diameter of the drive shaft.
  • the tensioning means is advantageously rope and / or belt-shaped and / or rotating body-like.
  • the type of rope and / or belt-shaped tensioning means preferably corresponds to the rope and / or belt-shaped force transmission means or suspension or propellant, so that reference is made to this description.
  • the rope and / or belt-shaped tensioning means has closed ends that form a loop.
  • the rotary body-like clamping means is preferably a disk or a roller or a drum or a wheel, etc. and rotates about an axis of rotation.
  • the force transmission means or the rope-shaped and / or belt-shaped tensioning means lie resting on a surface of this rotating body.
  • a tensioning device such as a fixed, ie stationary wall, plate, etc. can be used, in which the force transmission means or the rope and / or belt-shaped tensioning device slides over a surface.
  • Tensioning device is used to tension / relax the force transmission means and carrying or propellant and / or rope and / or belt-shaped tensioning means against the support body.
  • the tensioning device comprises at least two components of the elevator that tension or relax or relax the force transmission means and / or the suspension or propellant and / or the rope and / or belt-shaped tensioning means against the support body by relative movement.
  • the clamping device moves a first rotating body-like clamping means relative to another rotating body-like clamping means and / or a rotating body-like clamping means is moved relative to the drive and / or a rotating body-like clamping means is moved relative to the auxiliary pulley and / or the drive is moved relative to the support body.
  • the person skilled in the art can of course also use clamping devices with other known clamping mechanisms.
  • the diameter of the rotating body-like clamping means can also be increased / decreased without the need for a relative movement of the same.
  • such a variation in diameter of the rotating body-like clamping means takes place by spreading / folding a surface of the rotating body-like clamping means.
  • the person skilled in the art has many options available in this regard.
  • the considerations for rotary body-like clamping devices naturally also apply to clamping devices such as a fixed, ie stationary wall, plate, etc.
  • the support body can have any shape.
  • the support body is advantageously part of an outer circumference of a rotary body, such as a disk or a roller or a drum or a wheel or part of an outer circumference of a wall or a plate.
  • this rotary body is freely rotatable about an axis of rotation.
  • the diameter of this rotating body is advantageously circularly symmetrical.
  • the wall or plate is advantageously fixed, ie stationary.
  • the primary function of the support body is to provide the force transmission means and the suspension or propellant with a stable base for optimal transmission of the traction force.
  • the support body is thus designed to be stable enough to build up a counterforce to these traction forces.
  • Method for operating the elevator Components of the elevator, such as the drive and car, with functions such as the brake are advantageously integrated into the system.
  • system integration is understood to mean an optimization of individual components made from a system perspective, ie this optimization of the components is seen in the entire system of the elevator, coordinated with one another.
  • brake functions such as control brake, holding brake, deceleration brake and safety brake are allocated to individual, optimized components of the elevator.
  • the drive is advantageously made of lightweight materials such as steel, steel alloys, aluminum, aluminum alloys, carbon fiber, zylon, etc. With such a lightweight construction, only small masses are accelerated or braked when the drive is operating.
  • the drive therefore preferably has only one control brake 5 ' .
  • the speed of the cabin is kept approximately constant or the speed of the cabin follows a set curve.
  • the control brake absorbs potential energy and thus prevents its conversion into kinetic energy.
  • the support body of lightweight materials such as steel, steel alloys, aluminum, aluminum alloys, carbon fiber, Zylon, etc .
  • the support body is a spoked wheel with hub, spokes and rim.
  • a separate brake is preferably not provided for the support body.
  • the drive and / or the support body and / or the force transmission means and / or the support or propellant and / or the tensioning device are made of lightweight materials, as a result of which these components have relatively low masses and what makes it possible to use the tensioning device as a holding brake 40 .
  • the tensioning device fulfills a holding function if it protects stationary masses against unwanted movement due to their weight or other forces acting in the direction of movement. This is advantageously achieved by variably adjusting the clamping force in height.
  • the tension force with which force transmission means and suspension means or propellant act on the support body is preferably increased. This increased tensioning force is preferably reduced again at the time of leaving the floor.
  • At least one brake of the cabin is advantageously used as a deceleration brake 7 ' and / or a catch brake.
  • the cabin deceleration brake is preferably a rail brake which absorbs kinetic energy and thereby delays the speed of movement of the moving masses.
  • the person skilled in the art can of course use other brakes as a deceleration brake, for example he can use a drum brake, etc.
  • the drive, the force transmission means, the suspension or propellant, the tensioning means and the support body are advantageously arranged in a shaft of the elevator, preferably in the shaft head of the elevator. Due to the often limited space in the shaft and with the aim of making the best possible use of the space in the shaft, the arrangement of the components can be freely arranged within the scope of the disposition parameters.
  • the force transmission means is an inexpensive and easily replaceable wearing part, for example a belt made of plastic, while the suspension means or propellant and the support body are long-lasting capital goods that cannot be replaced or only very rarely.
  • the force transmission means can thus be replaced simply and quickly in a method for servicing the elevator.
  • a force transmission means to be replaced is relaxed against the support body from its tensioned operating position.
  • the power transmission to be replaced is removed.
  • a replacing power transmission means is positioned in place of the power transmission means to be replaced.
  • the replacing power transmission means is clamped against the support body.
  • a force transmission means to be replaced is either by relative movement of a clamping means with respect to the drive ( FIG.
  • the suspension or propellant is not removed from the support body when the force transmission means is changed ( FIGS. 2 to 4 ).
  • a rope and / or belt-like tensioning means to be replaced is either by relative movement of rotating body-like tensioning means to each other (FIG. 3) or by relative movement of rotating body-like tensioning means with respect to the drive and the auxiliary pulley ( FIG 4 ) excited / relaxed.
  • the power transmission means and / or the rope and / or belt-shaped tensioning means can be replaced together or separately.
  • the force transmission means and the tensioning device can be retrofitted in elevators, particularly in the case of modernizations.
  • existing elevators can be modernized quickly and easily with power transmission means and tensioning devices.
  • the traction sheave of an existing elevator is separated from its drive.
  • the traction sheave and / or the drive is preferably removed.
  • a support body is preferably installed instead of the traction sheave or the traction sheave is used as a support body.
  • a small-sized drive is preferably installed instead of the existing drive, or the existing drive is used further.
  • the power transmission means moving the carrying or propellant is mounted.
  • the force transmission means is preferably mounted on the carrying or propellant means via a tensioning device. Power transmission means as well as suspension or propellant are tensioned against the support body.
