Description

The present invention relates to an elevator transportation device for persons and/or objects. Furthermore, the invention relates to a method for transporting people and/or objects with an elevator transport device according to the invention and the use of the elevator transport device according to the invention for transporting people and/or objects. Furthermore, the invention relates to a kit of parts comprising an elevator transportation device according to the invention and a building, in particular a high-rise building.

Elevator conveying devices for persons and/or objects are sufficiently known from the prior art. Conventional systems include cable elevators, traction sheave elevators, hydraulic elevators, rack and pinion elevators, electromagnetic elevators or vacuum elevators. What all these systems have in common is that they are dependent on the supply of large amounts of external energy.

One approach to reducing the high energy consumption of known systems is to utilize the buoyancy principle of floating bodies in or on a liquid, in particular water.

The EP 3 279 128 A1 discloses a device for transporting people and/or goods, comprising at least two shafts which are connected to one another according to the principle of communicating tubes and in which a liquid is arranged. At least one of the shafts is designed as a lift shaft, with a lift pulpit being arranged floating on the liquid in the lift shaft and the lift pulpit having a basket with a floor and weight elements arranged under the floor. However, this system has the disadvantage that liquid must be actively pumped from one of the two tubes into the other in order to convey the elevator car.

The DE 2020 15 006 773 U1 also discloses a passenger/lift and/or goods/lift elevator comprising a floating buoyancy unit directly and/or indirectly connected thereto. The buoyancy units are used to enable ascents and descents in buildings from approx. 100 m and up to approx. 800 m and higher with their encapsulated buoyancy energy. This should be done with absolute independence of the supply of permanently flowing mains power, through the law of gravitation for descents, for ascents through/with floating buoyancy units, on the basis and calculation of the own weight, with the help and in the nano range computer-aided calculated, currently existing or constantly changing recorded, or constantly changing delivered total weight of persons and/or goods. The disclosed elevator system is based on the buoyancy principle. However, this system also leaves something to be desired, especially with regard to the braking system used and the recovery of energy, which can contribute to further improving the energy balance of elevator systems based on the lift system.

In order to overcome the disadvantages of the elevator systems known from the prior art, the invention was based on the object of providing an elevator system that enables operation that is as resource-saving as possible and at the same time is further improved, in particular with regard to the driving behavior of the buoyancy units.

Accordingly, an elevator transport device for persons and/or objects was found, comprising at least one liquid-flooded or liquid-floodable tube, comprising a tube wall with an inner tube wall and an outer tube wall, at least one floating unit arranged in the tube, in particular concentrically, in particular several concentrically arranged Floating units, with an inside and outside, at least one transport cabin arranged or arrangeable, in particular arranged outside of the tube, in particular several transport cabins, with at least one cabin door and a cabin wall with a cabin inside and cabin outside and optionally at least one transport channel, in particular elevator or Elevator shaft, wherein the at least one transport cabin and the at least one floating unit can be or are connected to one another via one or more connecting units, the at least one transport cabin being controllable, in particular height-adjustable, via the at least one floating unit of the at least one tube that is flooded with liquid or can be flooded with liquid , wherein the swimming unit has at least one pump system and at least one supply unit, comprising at least one compressor, wherein the at least one floating unit comprises at least one buoyancy body, in particular in the form of at least one air chamber, in particular compressed air chamber, and/or, in particular and, at least one driven body, in particular in the form of at least one ballast tank, the at least one Swimming unit has at least one, in particular central, penetration channel, comprising a channel inside and channel outside, which extends through the at least one swimming unit, in particular through the at least one buoyancy body and the at least one driven body, and optionally the at least one supply unit. With the elevator transportation device according to the invention, it has surprisingly been shown that the floating units, which have at least one penetration channel, have an optimal liquid flow function and thus allow smooth and trouble-free sliding stability of the floating unit, which leads to improved driving characteristics of the elevator transportation system.

Preferred are those embodiments in which the at least one penetration channel extends through the at least one swimming unit, in particular through the at least one buoyancy body and the at least one driven body, as well as the at least one supply unit.

In an alternative embodiment of the elevator transportation device according to the invention, in which the at least one floating unit has only one penetration channel, this is preferably attached concentrically.

The tube may suitably have a round cross-section or a polygonal cross-section. In this case, the tube and/or the at least one swimming unit can be set up and designed in such a way that several swimming units and transport cabins connected to these swimming units move simultaneously on a horizontal plane of the tube with one another in one direction and/or past one another in opposite directions.

In an alternative embodiment, the elevator transport device has a transport channel, in particular an elevator or lift shaft, which completely or partially encloses the transport cabin and is separate from the liquid-flooded or liquid-floodable tube. It is also conceivable that the liquid-flooded tube or tube that can be flooded with liquid is designed in such a way that only part, for example half, of a tube, for example round, is or can be flooded with liquid and the portion of the tube separated by a partition represents the conveyance channel.

Such elevator transportation devices according to the invention have proven to be advantageous in which the penetration channel is designed and set up for the liquid surrounding the at least one floating unit to flow through, the at least one penetration channel also having two openings, each with an opening edge and an inner diameter, in particular one inner diameter which is smaller than the diameter of the opening in the area of the opening edge. Even better flow properties of the swimming unit can be achieved through the penetration channel that tapers in the area of its openings.

In a further embodiment of the elevator transportation device according to the invention, it can be provided that the tube has at least one receptacle on its inner tube wall, in particular in the form of at least one guide rail, and that the at least one floating unit has at least one force converter on its outside, in particular in the form of at least one wheel or a roller, wherein the at least one receptacle, in particular in the form of the at least one guide rail, is designed and set up to accommodate the at least one force transducer, in particular in the form of at least one wheel or one roller, in a height-adjustable manner and/or that the tube on the inner tube wall of which has at least one force converter, in particular in the form of at least one wheel or a roller, and that the at least one swimming unit has at least one receptacle on its outside, in particular in the form of at least one guide rail, the at least one receptacle, in particular in the form of at least one guide rail, is designed and set up to accommodate the at least one force transducer, in particular in the form of at least one wheel or a roller, in a height-adjustable manner.

In a further embodiment of the elevator transportation device for persons and/or objects, the at least one receptacle and the at least force converter represent or comprise an electromagnetic energy conversion system. The electromagnetic energy conversion system can be designed and set up in particular to generate electrical energy through the movement of the force converter in the receptacle during ascents and/or descents, in particular and the at least one swimming unit, with the energy production system being designed and set up to generate electrical energy to provide electrical energy to the elevator transportation device for persons and/or objects.

In a preferred embodiment of the elevator transportation device according to the invention, the liquid in the liquid-flooded or liquid-floodable tube is water, preferably water with a temperature of >0°C, in particular with a temperature of 4°C. Under standard conditions, water has its greatest density at approx. 4°C, which has a positive effect on the flow properties of at least one swimming unit.

Such embodiments are preferred in which the liquid in the tube comprises water and additives, in particular rheology-modifying additives. The temperature of the liquid comprising water and additives can expediently be selected in such a way that its density in the liquid state leads to improved driving properties of the at least one swimming unit.

In a further embodiment of the elevator transport device according to the invention for people and/or objects, the at least one liquid-flooded or liquid-floodable tube between the inner tube wall and the outer tube wall comprises a temperature control system designed and set up to keep the temperature of the liquid in the tube constant.

The temperature control system expediently comprises at least one temperature sensor and one or more temperature control units, e.g. heating and/or cooling units. In one embodiment, the at least one temperature sensor can be an integral part of the tube wall.

In a further embodiment of the elevator transportation device according to the invention, the at least one temperature sensor can be an external part of the tube wall, in particular in the form of at least one surface temperature sensor on the inner tube wall and/or part of the at least one floating unit.

The at least one temperature sensor is expediently designed and set up to detect anomalies in the water temperature and to transmit them to a data processing device, which in turn ensures that the standard temperature of the liquid in the tube is maintained by controlling the temperature control system of the tube.

In a further preferred embodiment of the elevator transportation device according to the invention, the supply unit comprises batteries and/or accumulators and/or, in particular and, a data processing device, with preferably the The position of the at least one supply unit within the at least one swimming unit can be changed linearly in the direction from the first opening end to the second opening end and/or, in particular or, from the second opening end to the first opening end. A supply unit designed in this way has several advantages. Electrical energy can be stored in the batteries or accumulators, so that the elevator transportation device is not necessarily dependent on a permanent external power supply. The movability of the supply unit further increases the flexibility in weight distribution within the swimming unit and makes it possible to adjust the volume or the weight of the buoyant or driven body at any time.

In a further preferred embodiment of the elevator transportation device according to the invention, the at least one driven body, in particular the at least one ballast tank, has at least one pump system designed and set up to suck liquid through valves, in particular inlet and outlet valves, in the wall of the floating unit, in particular when descending and/or a low transport load, or to be expressed, in particular in the case of the ascent and/or a high transport load.

Valves within the meaning of the invention can in particular also be high-pressure valves.

When descending from high building floors and consequently a low external pressure on the swimming unit, the at least one pump system allows the internal compressed air pressure to be released from the ballast tank chambers, in order to allow ballast liquid volumes to flow into the ballast tanks again via the valves, in particular the inlet and outlet valves to permit. The pump or compressor system also enables liquid volumes from the ballast tanks, via valves, in particular during driveways, based on the constantly available compressed air pressure capacity of the compressors, for example from approx. 100 to approx. 1000 bar, or depending on the height of the building also significantly higher pressures Inlet and outlet valves to squeeze into the surrounding liquid of the tube.

In a particularly preferred embodiment of the elevator transportation device according to the invention, the at least one connection unit comprises at least one oppositely polarized magnet on the floating unit and the transportation car. Alternatively or additionally, the connection unit between the at least one transport cabin and the at least one swimming unit can have at least one ball bearing-gear wheel-rotary axis unit, designed and set up to create a non-positive connection with the gear wheels located at the ends of the axis of rotation with the respective at least one guide rail attached to the outer sides of the at least one transport cabin and the at least one swimming unit opposite the tube wall. In a specific embodiment, it can be provided that the transportation cabin has at least one first guide rail on the outside of the cabin opposite the tube wall, designed and set up for interaction with gears, and that the swimming unit has at least one second guide rail on the outside of the floating unit opposite the tube wall and arranged to interact with gears. The connection unit between the at least one transport cabin and the at least one swimming unit has to include at least one ball bearing-gear wheel-rotary axis unit, designed and set up to create a non-positive connection via gear wheels located at the ends of the axis of rotation, optionally with the interposition of a gear system made up of several Gears to enter into the first and second guide rail.

The connecting units have surprisingly succeeded in ensuring a secure and reliable connection between the transportation cabin and the swimming unit. Despite the presence of an axis of rotation, which is guided through the tube wall, it is ensured that no liquid can escape from the liquid-carrying tube to the outside. At the same time, guide ropes can be dispensed with with such a connection unit connecting the swimming unit and the transport cabin. The ball bearing, gear and pivot units are designed and arranged such that movement of the flotation unit initiates unidirectional movement of the carriage cabin. If the swimming unit moves up, for example, the transport cabin also moves up. For this purpose, the ball bearing-gear wheel-axis of rotation unit optionally has a system of several gear wheels which mesh with one another in such a way that the swimming unit and the transport cabin can move in the same direction, as described above.

In a further embodiment of the elevator transportation device according to the invention, the at least one connection unit, which comprises the at least one ball bearing-gear wheel-axis of rotation unit, comprises seals, in particular seals seamlessly integrated into the tube wall. Such seals should essentially, in particular completely, prevent the liquid in the tube from escaping.

The tightness at the seams of the column wall, in particular at the connecting units, is thereby affected by the liquid pressure acting inside the tube on the inner Seals guaranteed. It can be provided here that the at least one connection unit comprises a housing, with the housing representing the boundary between the connection unit and the tube wall, with the housing tapering in the direction of the outer tube wall.

In a particularly energy-efficient embodiment of the elevator transportation device according to the invention, at least one energy generation unit is located along the at least one penetration channel of the at least one swimming unit, in particular in the form of at least one water wheel, at least one water shovel or at least one water paddle, the at least one energy generation unit being and/or, in particular and, driving down the swimming unit in the liquid flow generated at least one penetration channel can be driven. Surprisingly, it has been shown that the penetration channel not only improves the flow properties of the at least one swimming unit, but can also be used to place at least one energy generation unit in the at least one penetration channel. When the at least one swimming unit ascends and descends, this can reliably convert kinetic energy into electrical energy and make it available to the elevator transport device. This significantly increases the energy efficiency of the system.

In a further embodiment of the elevator transportation device according to the invention, there is at least one energy generation unit on the outside of the at least one floating unit, in particular in the form of at least one water wheel, at least one water shovel or at least one water paddle, the at least one energy generation unit being generated by the up and down movement of the at least one swimming unit generated liquid flow can be driven.

In a particularly preferred embodiment of the elevator transportation device according to the invention, the at least one tube, in particular a tube flooded with liquid, comprises at least one first electromagnetic energy converter on its tube wall inside and/or outside of the tube, in particular also comprising at least one braking and recuperation system, the at least one first electromagnetic Energy converter is designed and set up to convert the kinetic energy of the at least one swimming unit into electrical energy, and in particular to store it in the batteries located in the at least one supply unit and/or, in particular, to brake the elevator transport device. Alternatively as well as in particular In addition, the at least one transport cabin can have at least one second electromagnetic energy converter on its outside adjacent to the tube wall, in particular also comprising at least one braking and recuperation system, wherein the at least one second electromagnetic energy converter is designed and set up to convert the kinetic energy of the transport cabin into electrical energy , as well as in particular in the accumulators located in the at least one supply unit, and/or, in particular and, to brake the elevator transport device. Surprisingly, it has been shown that braking and recuperation systems can be used particularly advantageously for the elevator transportation devices according to the invention, which are based on the buoyancy principle. Thus, an optimum transport speed is constantly achieved by permanent electromagnetic braking of the elevator transport device. At the same time, electrical energy can be recovered from the electromagnetic fields moving past each other on ascents and descents by converting kinetic energy into electrical energy. This electrical energy can then either be consumed directly by the elevator transportation device or stored in the accumulators of the at least one floating unit. It is thus possible to operate the elevator transportation device according to the invention in a substantially self-sufficient manner without having to rely on the constant supply of external electrical energy. It is of course possible, if required, especially when the vehicle is idle, to feed additional electrical energy from the mains into the batteries of the at least one supply unit.

In a further embodiment of the elevator transportation device according to the invention, the at least one floating unit has at least one compressed air pipe on the inside of the channel surrounding the at least one penetration channel, comprising valves, in particular inlet and outlet valves, with the at least one compressed air pipe being located between the two, in particular parallel to the inside of the channel openings, wherein the at least one compressed air pipe is designed and set up to press air, in particular hot and/or cold air, via the at least one compressor of the at least one supply unit into the at least one buoyancy body, in particular the at least one compressed air chamber, of the at least one swimming unit and/or letting the air out of the at least one buoyancy body, in particular the at least one compressed air chamber. The outer compressed air tubes ensure the internal back pressure equalization of the swimming unit in a surprisingly efficient manner in order to counteract the swaying External pressures acting on the outer shell of the at least one swimming unit, which can change depending on the height of the water column acting on the swimming unit.

The control of the buoyancy and downforce of the at least one floating unit can be improved in a further embodiment of the elevator transportation device according to the invention in that the at least one buoyancy body, in particular in the form of at least one compressed air chamber, has a temperature control system on its inside that is designed and set up to temper the compressed air in the at least one buoyancy body, in particular in the at least one compressed air chamber, in particular to heat or cool it. The connection of a temperature control system leads to a heating of the air volumes in the buoyancy body and thus to a change in the density of the air. The temperature control can be continuously throttled, which leads to a continuous reduction of the buoyancy energy. Ultimately, the temperature control system can thus surprisingly help in principle to ensure constant ascent and descent speeds.

In a further embodiment of the elevator transportation device according to the invention, the at least one, in particular liquid-flooded, tube comprises at least one lock, in particular a large number of locks, the at least one lock being designed and set up to block the vertical mobility of the at least one swimming unit, the at least one lock preferably can be controlled by a central control device of the elevator transportation device. Such locks have the advantage that partial areas of the liquid-carrying tubes can be separated at any time. This increases the safety of the overall system, especially at great heights.

In a particularly safe embodiment of the elevator hoisting device according to the invention, the at least one hoisting car, in particular all hoisting cars, comprises at least one electric motor, designed and set up to move the hoisting car upwards and/or downwards, in particular upwards, in particular if the at least one floating unit connected to it fails drive, wherein the electric motor, in particular the electric motors, is/are preferably controllable by the central control device of the elevator transportation device. The provision of an electric motor has the advantage that, in the event of a failure of the buoyancy function of the elevator transportation device, mobility of the elevator transportation device can still be ensured. Thus, even in an emergency, passengers can be transported to the next exit. In this way, in an emergency, a possible rapid rescue of the transport cabin occupants are made possible. It can also be provided that the at least one electric motor can also be controlled directly from the transport cabin in an emergency situation.

In a further particularly safe embodiment of the elevator transport device according to the invention, the at least one transport car, in particular all transport cars, comprises an emergency braking system designed and set up to stop the transport car, in particular in the event of failure of the at least one swimming unit connected to it, in particular when descending, the emergency braking system in particular the braking systems, can be controlled by the central control device of the elevator transportation device. Such a braking system can prevent the elevator carriage from falling in an emergency. Provision can also be made for the emergency braking system to be controllable directly from the carriage cabin in an emergency situation.

The central control device is generally a data processing device, which is housed in a monitoring center, for example, from which one and/or more, in particular more, elevator transportation devices can be monitored and controlled. In dangerous situations in particular, the central control device can control the elevator transportation device to avert danger. Provision can also be made for the at least one lock, the at least one electric motor and/or the at least one emergency braking system to be controlled directly from the carriage cabin.

In a further embodiment of the elevator transport device according to the invention for persons and/or objects, the at least one floating unit comprises at least one collision protection, in particular a collision protection based on sound wave measurement, in particular in the area of the openings of the penetration channel. The collision protection can reliably prevent a collision of the at least one swimming unit when the at least one swimming unit ascends and/or descends, in particular when several swimming units, each connected to a transport cabin, are moving in a tube. In this case, several swimming units, each of which is connected to a transport cabin, can move parallel to one another, for example in oncoming traffic, if the tube is designed to be large enough.

In a particularly preferred embodiment of the elevator hoisting device according to the invention, the at least one hoisting car, in particular all hoisting cars, also comprises at least one load sensor designed and set up to determine the total weight of the people and/or objects, in particular and in the hoisting car. The at least one load sensor is preferably connected to the data processing device of the swimming unit, the data processing unit being designed and set up to activate or deactivate the at least one pump system if the overall weight is too high. The transport speed can be optimally controlled by accurately detecting the total weight of the at least one transport cabin. This has the advantage that trouble-free travel is ensured regardless of the total weight of the at least one transport cabin.

In a further particularly preferred embodiment of the elevator transportation device according to the invention, the data processing device is designed and set up to keep the transportation speed constant by controlling the total weight of the at least one swimming unit and the at least one transportation cabin connected thereto. In this case, the total weight of the at least one swimming unit and the at least one transport cabin connected thereto can be controlled dynamically in a computer-based manner. Controlling the total weight of the swimming unit provides for a dynamically adapting speed of the swimming unit and thus ensures that the elevator carriage can react to changing system parameters such as weight, buoyancy, external pressure or temperature at any time. This makes a pleasant and trouble-free transport possible.

With the elevator research devices according to the invention, the energy consumption can also be reduced significantly compared to conventional claim systems. Furthermore, it has surprisingly turned out that by additionally using at least one braking and recuperation system, electrical energy can also be recovered during transportation, so that the energy consumption of the elevator transportation device in the form of external electrical energy can essentially be ruled out. Systems in which several different energy recovery systems are used have proven to be particularly advantageous, so that the generation of electrical energy during transport can be increased even further. This leads to particularly energy-efficient elevator transportation devices.
