Definitions
- the present invention relates to a car arrangement for a double-deck elevator and a double-deck elevator with such a car arrangement.
- a double-deck elevator is characterized by a car arrangement with a car frame and two cabins arranged one above the other. Using the two cabins arranged one above the other, two different floors lying one above the other can be approached at the same time.
- the floors have different heights, resulting in different vertical distances between elevator access points. So that floors of this type can be approached with a double-deck elevator without any problems, it must be possible to adapt the vertical distance between the two cars of a double-deck elevator to the corresponding floor heights and corresponding distances between the entrances. To adjust this vertical distance, at least one of the two cars can be displaced in the vertical direction relative to the other car and generally relative to the car frame. This vertical displacement takes place by means of a displacement device.
- the displacement device can have, for example, one or more screw spindle drives and/or scissor-like connecting members, via which the two cabins are connected to one another.
- a spindle drive has at least one spindle and a toothed rack in which the spindle engages.
- the spindle can be arranged on the car frame of the car arrangement or on the car to be moved. Accordingly, the toothed rack can be arranged on the car to be moved or on the car frame.
- a hydraulic displacement device can be provided for displacing the cabin. The distance between the cabins can be adjusted while driving by means of a controller to the floor distance between the two floors to be approached and the corresponding distance between the entrances.
- EP 3 514 096 A1 describes a double-deck elevator with two cars, in which a vertical distance between the cars can be adjusted by means of a pull chain and a number of deflection elements.
- the corresponding drive device increases the height of the corresponding car arrangement.
- US 2020/0239289 A1 describes a linear chain in which chain links of the linear chain engage in a form-fitting manner under pressure load in such a way that a force-absorbing section of the linear chain is stable under pressure load in a direction in which the chain links can be pivoted relative to one another if there is no pressure load.
- WO 2015/043766 A1 describes an elevator with two cars, each of which can be displaced independently of one another in an elevator shaft by means of a drive.
- the cabins can be temporarily coupled to one another by means of a mechanical coupling element, for example in the form of a support chain.
- the distance between the coupled cabins is adjusted by means of the drives assigned to the cabins.
- the size of the elevator shaft plays an important role.
- the displacement device In order not to have to increase the size of the elevator shaft, the displacement device should take up as little space as possible, particularly in the horizontal direction.
- both of the aforementioned displacement devices require a relatively large amount of space, specifically in the horizontal and in the vertical direction, with the space available in the horizontal direction in an elevator shaft in particular usually being very limited.
- the hydraulic displacement device produces an odor due to the oil used in it can tend, whereby the odor can possibly be perceived as unpleasant in the corresponding cabin.
- a first aspect of the invention relates to a car arrangement for a double-deck elevator.
- the car arrangement has a car frame, a first car, a second car, a linear chain and a drive device.
- the first cabin is coupled to the car frame.
- the second car is arranged on the car frame above or below the first car.
- the second car is coupled to the car frame so that it is vertically movable relative to the car frame and relative to the first car.
- the rigid chain is coupled to a first end of a force absorbing section of the rigid chain with the first cabin or the car frame.
- the linear chain is coupled to the second cabin with an opposite, second end of the force-receiving section.
- the rigid chain is arranged in such a way that the second cabin exerts a pressure load on the force absorbing section of the rigid chain due to gravitation.
- the drive device is coupled to the rigid chain and is designed to displace the second car in the vertical direction relative to the first car by means of the rigid chain.
- the second car which is arranged in the car frame so that it can move vertically above or below the first car, can be displaced in the vertical direction relative to the first car, so that the vertical distance between the cars can be adjusted, in particular as a function corresponding entrances to the cabins on different floors of a building.
- the vertical distance is adjusted in particular by changing the length of the force absorbing section, this length being effected by a movement of the rigid chain by means of the drive device.
- the car frame can generally be understood to mean a frame that can be moved between several levels or floors, for example in an elevator shaft, with at least one cabin, or in the present case a double-deck elevator with at least two cabins, for transporting people or loads.
- the car frame can in particular be a frame-like construction for supporting the cabins and is also called a sling frame, among other things.
- the car frame can be guided, for example, along at least one guide rail running in an elevator shaft. Such guide rails can be arranged on one side or on two opposite sides in the elevator shaft.
- a safety gear can be integrated into the car frame, which serves to brake the car frame in the event of overspeed.
- the car frame can comprise the two double-decker cabs for simultaneously approaching the two different floors.
- a displacement device can be arranged, by means of which at least one of the two cabins can be displaced in the vertical direction relative to the other cabin and generally relative to the car frame.
- the aforementioned drive device and the rigid chain form such a displacement device.
- the approach presented here proposes realizing the shifting of the second cabin by means of the rigid chain.
- the vertical distance between the cabins is determined by the length of the force absorbing section of the linear chain. This length can be adjusted by means of the drive unit, as a result of which the second cabin is displaced relative to the first cabin.
- a guide structure is additionally arranged inside the car frame, in which the two cars are arranged one above the other, in order to guide the car to be shifted during its movement.
- the weight of the second cabin rests on the rigid chain.
- the section of the rigid chain on which the weight is applied and which accordingly bears the weight of the second cabin is the force absorbing section.
- the linear chain must be longer than the force absorption section so that the length of the force absorption section can be changed.
- the section of the rigid chain on which the weight of the second cabin does not bear can be referred to as the remaining section of the rigid chain.
- the length of the remaining portion changes depending on the length of the force receiving portion. In particular, the length of the residual section increases as the length of the force absorbing section decreases, and vice versa.
- the linear chain has impact properties. Therefore the linear chain cannot tear.
- the linear chain and the drive device that drives it require only a relatively small amount of space, especially in the horizontal direction, compared to the spindle drive and the hydraulic displacement device.
- the drive device can generally be understood as a motor, by which the linear chain is moved in such a way that the length of the force absorbing section of the chain changes, so that the corresponding cabin, for example the second cabin, is raised relative to the car frame and the first cabin and /or can be lowered.
- the linear chain can be designed in such a way that chain links of the linear chain engage in one another in a form-fitting manner under a compressive load such that the force-absorbing section of the linear chain under the compressive load a direction in which the chain links of the linear chain can be pivoted against one another when there is no pressure load.
- the rigid chain can always be stable in a first lateral direction, which is perpendicular to a longitudinal direction of the rigid chain when the rigid chain is unrolled, and can be stable in a second lateral direction, which is perpendicular to the longitudinal direction of the rigid chain when the rigid chain is unloaded and/or unrolled is perpendicular to the first lateral direction, be unstable at the transition of the chain links, in particular pivotable, in particular bendable.
- the chain links of the linear chain can engage in a form-fitting manner under the pressure load in such a way that the linear chain is stable in the second lateral direction. The linear chain can thus withstand high pressure loads.
- the drive device can be designed and coupled to the linear chain in such a way that when the second cabin is displaced in the direction of gravity, the linear chain drives the drive device as a generator.
- the potential energy stored in the raised second cabin can be converted into electrical energy by means of the linear chain and the drive device in generator mode.
- the weight of the second cabin acts on the rigid chain, which drives the drive device, which in turn acts as a generator and generates the electrical energy.
- the electrical energy can be stored and can be reused, for example, the next time the second car is moved to supply the drive device with energy.
- the drive device can have the motor and an output, which is arranged on a shaft of the motor and is in engagement with the linear chain.
- the output can be formed, for example, by a gear whose teeth engage in the chain links of the rigid chain.
- the drive device can also have a housing and/or a guide for the remaining section and optionally a part of the force-absorbing section of the linear chain.
- the motor and/or the remainder section can optionally be arranged in or on the housing.
- the drive device if the linear chain is coupled to the first cabin, the drive device can be arranged on the first cabin or on the second cabin. Alternatively, if the linear chain is coupled to the car frame, the drive device can be arranged on the car frame or on the second car. The drive device can thus engage in the linear chain at the first end of the force-absorbing section or at the second end of the force-absorbing section.
- the rigid chain can be arranged in such a way that the remaining section of the rigid chain that is not the force absorbing section is arranged between the cabins. This is particularly advantageous when the linear chain is coupled to the first cabin. For example, if the rigid chain is coupled to the first cabin, the remaining section can be guided along the cabin on which the drive device is arranged.
- the rigid chain can be arranged in such a way that the remaining section of the rigid chain extends at least partially in the horizontal direction. This can contribute to the fact that the vertical space requirement of the displacement device is particularly small.
- the first car can have a first force absorption area
- the car frame can have the first force absorption area
- the second cabin can have a second force absorption area.
- the linear chain can be coupled to the first force absorption area with the first end of the force absorption section and to the second force absorption area with the second end of the force absorption section.
- the force receiving section can extend from the first force receiving area to the second force receiving area.
- a vertical distance between the two cabins depends on a length of the force absorbing section.
- the drive device can be designed to move the linear chain in order to displace the second cabin in the vertical direction in such a way that the length of the force absorption section changes.
- the second force absorption area is the area where the weight of the second cabin is transferred to the force absorption section of the linear chain.
- the first load bearing area is the area where the corresponding compressive load is transmitted from the load bearing portion to the first car or car frame.
- the drive device can be arranged at the first end or at the second end of the force-receiving section. At the end of the force-receiving section, on which the drive device is arranged, the drive device, for example its output, can form the corresponding force-receiving area.
- a rotatable deflection device for example a toothed wheel, which meshes with the linear chain, can be arranged at the first end or at the second end of the force-receiving section. In this case, the deflection device can form the corresponding force absorption area.
- the first car can be coupled to the car frame in such a way that it is arranged such that it can be moved in the vertical direction relative to the car frame.
- the car arrangement can have a further linear chain, which is coupled to the first car and the car frame.
- the elevator car arrangement can have a further drive device which is coupled to the further linear chain.
- the additional drive device can be designed to displace the first car in the vertical direction relative to the car frame by means of the additional linear chain.
- both cars can be shifted in the vertical direction relative to the car frame, with the further linear chain being able to be arranged for shifting the first car.
- the further rigid chain for moving the first car can be referred to as the first rigid chain and the rigid chain for moving the second car can be referred to as the second rigid chain.
- the relocation of the first car in addition to the relocation of the second car allows greater latitude and/or greater speed in understanding the vertical distance between the cars as a function of the different floor heights.
- the elevator car arrangement can have exactly one single linear chain for the vertical displacement of the second car.
- two or more push chains for example four push chains each, can be arranged.
- the drive devices for adjusting the corresponding rigid chains must be synchronized with one another in order to prevent the corresponding cabin from tilting and/or jamming.
- arranging only a single linear chain for moving the second cabin makes it possible to dispense with this synchronization. This contributes to the fact that the elevator car arrangement can be produced in a particularly simple and cost-effective manner if there is only one linear chain.
- the rigid chains can act on two diametrically opposite corner sections of the corresponding cabin.
- a second force absorption area can be arranged on the diametrically opposite corner sections of the second cabin.
- Two diametrically opposite corner sections can be understood to mean two corner sections of the corresponding cabin, each lying on a diagonal of an underside of the corresponding cabin.
- the lifting force can be understood to mean a force for raising and/or lowering the corresponding cabin.
- the rigid chain can be attached to the second cabin in alignment with the center of gravity of the second cabin.
- the linear chain can attack the second cabin directly below the center of gravity of the latter. This is particularly advantageous if only a single linear chain is arranged for moving the second car. In particular, this can contribute to avoiding the tilting and/or canting of the second cabin.
- a second aspect of the invention relates to the double-deck elevator.
- the double-deck elevator has the car arrangement explained above and a control unit which is configured to control the drive device of the car arrangement depending on the floor distance between a first floor and a second floor in such a way that in a stopping position of the car arrangement the first car is above the first floor is accessible and the second cabin via that second floor is accessible.
- Information about the distances between the floors of the corresponding building and/or the corresponding entrances can be stored, for example, in a memory unit of the control device, for example in the form of a look-up table in which the floors and their distances are assigned corresponding actuating signals for the drive device.
