Description

Built-in Elevator Circulation System {ELEVATOR CIRCULATING SYSTEM HAVING STACKED ELEVATOR AT END OF CIRCULATING TRACK}

The present invention relates to an elevator or other lifting device, and more particularly, to an elevator system capable of transporting passengers or cargo while circulating a car of an elevator without wires or ropes.

An elevator is a device that carries a person or cargo vertically and vertically in response to gravity, and is used not only in high-rise buildings but also in low-rise buildings. In general, the elevator has a rope-type elevator and a hydraulic type elevator depending on the driving method, and a screwless type, a rack-and-pinion type, etc., and a ropeless elevator using a linear motor instead of a traction type have appeared.

The rope-type elevator has a machine room for driving the elevator on the uppermost floor, and a traction machine of the machine room connects the car and the balance weight by ropes to move the cabin up and down. These machine rooms can be disadvantageous to buildings for several reasons, such as height restrictions.

Recently, a high-speed elevator has been developed along with the construction boom of skyscrapers, and a high-speed elevator that moves at a speed of more than about 60 km / h (1000 m / min) is being developed. There is also a double deck elevator with two elevators connected up and down to improve the transportation capacity, and there is also a twin elevator in which two elevators operate independently in one elevator passage.

Skyscraper buildings are demanding elevators that move more quickly to facilitate the transport of vertical lines. To increase the speed of the elevator, a tension proportional to the square of the speed is applied to the wire, and a high-speed elevator should be capable of supporting a large tension. Therefore, the cross-sectional area of the rope becomes larger and the weight of the rope increases. In addition, since rope lengths have to be lengthened by the long distance traveled by skyscrapers, in addition to the speed, the rope must be thicker due to the increased weight of the rope itself. In a skyscraper, it may eventually be heavier than the elevator's room.

For reference, an elevator is a low-speed elevator that moves at less than 45 m / min, a normal elevator that moves at 60 to 105 m / min, a high-speed elevator that moves at about 120 to 300 m / min, Speed elevator.

In fact, the rope weighs only 20 tons (t) of the ultra-high-speed elevators installed in the Burj Dubai building. In addition, since the weight of the balance weight is added up, the elevator is required to accelerate at a high speed. As the ropes eventually need to accelerate the heavily loaded elevator, the motor of the traction machine must also be provided with a significantly greater capacity than a conventional motor.

In addition, if the rope is longer than a few hundred meters, the length of the rope changes depending on the degree of wear of the rope or the temperature change. Therefore, the characteristics of the wire rope become more complicated and the control method becomes complicated.

The conventional screw type elevator employs a structure in which a long strut with a thread is formed and a sleeve corresponding to a nut is installed in a room. In the screw type elevator, since the room is raised and lowered by the rotation of the pillars, it is used when it is used for a small-sized simple elevator or when fluid movement is difficult.

It is expected that a ropeless elevator will be used instead of a conventional rope elevator in a skyscraper having 100 stories or more, and US Patent No. 5234079 discloses an elevator using a linear motor. However, since these linear elevators move in a floating state without a rope, it is necessary to secure the safety device as triple quadruple, and it is possible to move horizontally because there is no physical contact. However, in order to commercialize it, Very few elements are difficult to overcome.

In addition, a ropeless elevator using a worm gear-shaped driving body is also disclosed in U.S. Patent Publication No. 2002-0125075 and Korean Patent No. 10-1035068, but only the contents that can be moved only up and down are disclosed and further improved. Leave room for

The present invention provides an elevator system that can efficiently circulate the elevator using a ropeless elevator.

The present invention provides an elevator system having a structure that can safely support the cabin using physical contact, and uses a worm elevator that can increase the elevator efficiency without friction, and can easily circulate them.

The present invention provides an eco-friendly elevator system that can be practically high and can expect an energy regeneration effect.

According to an exemplary embodiment of the present invention, in a building including a first lifting space and a second lifting space, elevator system for improving the elevator operating efficiency by switching the elevator between the first lifting space and the second lifting space The elevator system may include a plurality of ropeless elevators moving along first and second lifting spaces and switch spaces formed at at least one end of both ends of the first and second lifting spaces, respectively, Among the elevators, the remaining waiting elevators except for a working elevator operating in the first and second lifting spaces are stored in a stopped state at a position adjacent to the switch space.

In the case of rope type elevators, due to the structural limitations provided by the ropes, the elevator is forced to move up and down, and only one elevator can move in one hoisting space. Of course, there are technologies that move two elevators in one hoisting space, but it is complicated and requires many technical restrictions to move more than three. However, ropeless elevators can implement an elevator system in which two or more elevators are arranged in one accommodation space because there is no rope, wire, or belt.

In addition, by forming a switch space at the upper end, the lower end, or both ends of the first and second lifting spaces, and allowing the waiting elevators among the plurality of ropeless elevators to be kept in a stopped state in the switch space, Only a part of the car is used, and when the number of passengers increases, the waiting elevator can be switched to the operating elevator.

If the switch space is defined at the top or bottom of the lifting space and the switch frame is installed in the switch space, the ropeless elevator can be moved from the switch space to the other lifting space using the switch frame. Although referred to herein as first and second lifting spaces for convenience, these lifting spaces may be extended to two or three or more, and these relationships may remain the same.

By being able to switch the elevator between the lifting spaces, the elevator can be controlled to circulate in one direction. For example, the first lifting space may provide one or two or more elevators that move only upwards, and the second lifting space may provide one or two or more elevators that move only downwards. In addition, in the case of partially operating the operating elevator and the standby elevator, the operating elevator does not circulate and can move passengers while moving up and down like a conventional elevator.

When passengers increase or usage increases, ropeless elevators can be circulated in only one direction. Of course, even in this case, some of the ropeless elevators may be partially moved in the opposite direction to transfer the close passengers first. When the elevator circulates only in one direction, the waiting time for the elevator can be significantly reduced, and the problem of rope entanglement can be solved by not using the rope.

In addition, the switch frame can transfer the ropeless elevator by linear reciprocating or rotating circulation in the switch space. In addition, when the transfer is carried out by circulating a plurality of ropeless elevators, the ropeless elevator is first used in the lifting space by using a waiting elevator. It is possible to smoothly switch the operating elevator that enters the switch space into the standby elevator after the injection.

The switch frame can be rotated in the moving member while performing linear reciprocation, rotational circulation, or the like, and through this rotation, the door direction can be switched to the desired direction.

Ropeless elevators can be provided with a variety of elevators. For example, it may be manufactured by a method using a linear motor, or may be manufactured by a method using a worm driving unit described later. In the case of using a worm driving unit, the ropeless elevator includes a worm driving unit moving along the lifting space, the cab moving together with the cabin, and a rotation axis parallel to the moving path of the cabin, and the lifting space and the switch frame. It may include a main guide and an extension guide corresponding to the worm driving unit.

The worm driving unit includes a wormgear body in the form of a wormgear, and the worm gear may be engaged with the support of the worm supporting parts arranged at equal intervals to provide a force for lifting. . Assuming that the worm drive unit itself can sufficiently provide the force necessary for lifting and lowering, and assuming that the support values of the worm support units are arranged at intervals of about 40 cm, the worm gear body is rotated at a rotation speed of about 900 rpm to about 360 m / min Can be realized sufficiently. Of course, the ultra-high speed of 600 ~ 1500m / min can be realized sufficiently.

Basically, the room part can be moved vertically by the interaction between the worm driving part and the worm supporting part, and the conventional rope is not used. Therefore, it is possible to overcome the inefficiency due to the weight of the rope even if it is used in a skyscraper, and energy can be efficiently used because it does not need to move the rope of tens of tons.

Various methods can be used for low resistance contact between the worm drive and the worm support. For example, rolling contact using a roller may be used, or a magnetic levitation may be formed using a permanent magnet, an electromagnet, or the like. Since the plurality of tooth surfaces slidably move on the worm supporting teeth in both the roller and the magnetic levitation, the room part can be moved without noise and vibration, and wear of the parts can be prevented, thereby increasing the service life of the parts.

In this specification, the term 'building' can be understood as a concept including a connecting structure connecting a building or a place, in addition to a general building, a tower, an apartment, etc. The elevating space is not limited to a closed space in a building, It may also include an open space.

Also, the car part is for supporting and protecting a person or a cargo, and may be provided in a state where the space in the room part is temporarily closed or partially opened, and a structure for conveying the room part without shaking Or rails may also be provided.

Since the lifting device of the present invention does not use a rope or a wire, it is possible to improve the inefficiency according to the massive weight of the rope, and a higher energy saving effect can be expected in a skyscraper or a superhighway elevator.

In particular, it is possible to transfer the ropeless elevator between the lifting space by using a switch frame, it is possible to provide a circulation structure of the elevator, it is possible to increase the transportation efficiency in the building.

By increasing the transport efficiency, the number of lifting spaces in the building can be reduced or optimally maintained, and the reduction of the lifting spaces allows the building's internal space to be more extensively reflected. That is, the lifting device of the present invention can reduce the number of lifting spaces by increasing the transport efficiency, and can effectively use its own area occupied by each lifting space, thereby ensuring a lot of living or living space in the same space. As a landlord, it can be said that the same amount of traffic can be maintained and a lot of land for sale can be secured, which is very economical.

In addition, the elevating device of the present invention can prevent the accidental fall of the cabin part even if the worst-case situation that the power is cut off or the braking device is disabled. Due to the characteristics of the worm gear, even if it is descending, when the motor stops, the descending speed is reduced smoothly and physically stopped.Even if the descending speed is maintained at a safe low speed even when moving, it is also excellent for occupant protection. Do. In this case, the burden on the stability of the braking device can be reduced, and a new need for braking can be applied.

In addition, when using the drive unit of the worm gear type, it is possible to move the cabin part with very little energy when falling, it is possible to reuse and accumulate energy using induction power generation. In particular, as described above, when the external power supply is accidentally cut off, power can be generated from the rotation of the worm drive due to the fall, and through the power produced by itself, the minimum control in the emergency situation, the minimum communication, the minimum It can be used for magnetic relief. In particular, when magnetic levitation is used for low resistance contact, the best effect can be obtained with a simple structure.

In the related art, as the building becomes higher, the length and the number of ropes increase, and as the rope lengths and speeds increase, complicated and expensive advanced technologies must be applied, and accordingly, many problems can be exponentially derived. However, the present invention using the worm drive unit can sufficiently cope with the high rise by the installation of the worm support, and the installation cost and burden does not increase even if the high rise continues. In addition, it is very easy to control the low speed, high speed, acceleration, deceleration by adjusting the rotational speed of the worm drive unit.

Since the elevator of the present invention does not need a machine room on the top floor, and does not need to provide a machine room on the top floor, the utilization of the top floor can be improved even in the architectural design, and the design can be freely performed even in the height limit of the building.

In addition, in the worm drive unit, the drive motor may be applied to the outside and inside of the worm gear body. When the drive motor is applied to the inside of the worm gear body, that is, when the housing of the drive motor is formed as the worm gear body, the weight and volume of the worm drive unit may be increased. While significantly reducing, the output and efficiency of the worm drive can be greatly increased.

When a ropeless lifting system is developed, several cabins on a single track can run continuously at regular intervals, like trains running on rails. There is no limit and it can eliminate the inconvenience of having to change the rope periodically.

In addition, since the worm drive unit and the cabin part move independently along the arrangement of the worm support, the cabin part may be moved in an inclined direction rather than in a vertical direction, or may be moved along a curved path rather than a straight line. If a shift structure is developed, driving may be realized not only in the vertical direction but also in the horizontal direction.

1 to 3, the elevator system 100 may assume a building including two or three or more lifting spaces. In the description of the present embodiment, the first lifting space 110 and the second lifting space 120 will be described as a reference, and the first lifting space 110 is responsible for raising the elevator during circulation, and the second lifting space 120 is It is assumed that the elevator is responsible for descending, but in addition, it is also possible to operate three lifting spaces or to form in various combinations.

One or more circulating elevator systems may be provided in one building, and may also be mixed with conventional linear reciprocating elevator systems that are not circulating.

The circulating elevator system may also be classified according to a high speed or a low speed circulation, and in the case of a high speed circulation or a high speed mobile elevator, it may be configured to pass through a certain number of floor units or a specific floor instead of all the floors.

In the case of the circulation type, several ropeless elevators 200 can move together in one lifting space, and because they move only in one direction, users can also quickly move between floors by minimizing waiting time.

Referring again to the drawings, the elevator system 100 is installed in the first lifting space 110, the second lifting space 120, the upper switch space 130 and the lower switch space 140, specifically ropeless The switch 200 includes the elevator 200 and the switch frames 300 in the switch spaces 130 and 140. In the present embodiment, the ropeless elevator 200 uses a worm drive, which may be desirable, and describes the advantages of using a worm drive. However, different driving methods, for example, a linear motor or a rack and pinion type rope, are described. A lease elevator can also be constructed.

In the case of circulation, the elevator 200 rises through the first lifting space 110, and the lifted elevator 200 is lifted up by the switch frame 300 of the switch space 130 or the other lifting space 120. You can move to the lifting space. However, as shown in FIG. 2, when there are not many movements of passengers, only about two of six ropeless elevators 200 may be operated, which may move passengers while moving up and down without circulating like a conventional elevator. Can be.

Referring to FIG. 2, two standby elevators (wt) are stored in the upper switch space 130 and the lower switch space 140, respectively, and the first elevator space 110 and the second elevator space 120, respectively. A running elevator wk can run.

Referring to FIG. 3, the numbers of ① to ⑥ may be specified in the elevator 200 for convenience. The ①, ②, ④ and ⑤ elevators are the standby elevators, and the ③ and ⑥ elevators are the operating elevators. Then, when the ③ elevator is located in the upper part of the building and it is difficult to descend to the lower part, the ④ elevator, which is a waiting elevator by the central control system, may be directly raised from the lower switch space 140. That is, according to the density of the driving elevator wk in the first or second lifting spaces 110 and 120, the standby elevator wt waiting in the switch spaces 130 and 140 may be changed into the first or second lifting space 110. , 120) or the operating elevator may be recovered to the first or second lifting spaces 110 and 120.

4 is a configuration diagram illustrating another operation example of the elevator system of FIG. 2.

Referring to Figure 4, the elevator doors of each floor may be equipped with a count sensor 150 for counting or measuring the number of passengers. The count sensor 150 may count the number of passengers one by one, or may roughly identify the number of passengers waiting for the approximate passengers by frequency. In addition, although the count sensor 150 may be formed adjacent to the elevator door, in some cases, the count sensor 150 may be installed at the entrance of the building or the entrance of each floor office.

As described above, when the number of passengers increases, a nearby waiting elevator (ex. ④) may be ready to operate if the location of the operating elevator (ex. ③) is too far from the floor on which the passenger is located or if the increase in passengers is significant. have. As the standby elevator switches to the operating elevator, the number of operating elevators in the first lifting space 110 may increase.

As shown in (c), when the passengers increase further, another waiting elevator (ex. ⑤) in the lower switch space 140 may move horizontally and move below the first lifting space 110, and further It may be used for driving in the first lifting space 110.

5 is a configuration diagram illustrating a circulation process in the elevator system of FIG. 2.

Referring to FIG. 5, the plurality of ropeless elevators 200 may be circulated as a whole while moving the first lifting space 110 and the second lifting space 120. The elevator 200 may move horizontally in the switch spaces 130 and 140. After the horizontal movement, the elevator 200 may move in one direction or partially backtrack along the lifting space.

③ When the elevator approaches the upper switch space 130, ① elevator, which is one of the waiting elevators waiting in the upper switch space 130, is introduced into the second lifting space 120, and ② the elevator is lifting the second lifting space 120. Can move up).

Through this process, ③ elevator and ① elevator are switched at the same time substantially, the elevator 200 as a whole can be configured to circulate in the counterclockwise direction.

Although not shown, the elevators 200 may be controlled by a central control system, the front and rear elevators may maintain a safe distance while maintaining a minimum distance, and the operation of the operating elevator and the waiting elevator is also a central control system. Can be controlled from

Figure 6 is an enlarged view for explaining the upper end of the elevator system according to an embodiment of the present invention.

Referring to FIG. 6, the switch frame 300 located in the upper switch space 130 allows the entrance of the elevator 200 to be opened by the lower portion thereof, and enables downward transmission of the elevator 200 after the position movement.

In addition, as shown, the elevator 200 descending along the second lifting space 120 may enter the other switch frame 300 in the lower switch space 140, after entering the switch frame ( After the position is changed by the reference numeral 300, it may be moved upward along the first lifting space 110 again.

In the present exemplary embodiment, the elevator 200 may be transferred from the top or the bottom of the first lifting space 110 and the second lifting space 120 while the switch frame 300 is horizontally moved or rotated. When the elevator 200 enters one of the switch frames 300, it moves to another lifting space, and after the movement, another switch frame 300 may be located in an empty place to allow another elevator 200 to enter. In addition, the elevator 200 moved at the same time can send the elevator 200 down in another lifting space.

When the switch frame 300 is located on a specific lifting space, the joint 320 may protrude from the bottom or the top of the switch frame 300 to be bound to the lifting space in the correct position. The elevator 200 may move smoothly by maintaining the state in which the main guide 470 and the extension guide 370 of the shape coincide.

FIG. 7 is a block diagram illustrating a ropeless elevator according to an embodiment of the present invention, FIG. 8 is a plan view illustrating a worm driving unit of the ropeless elevator of FIG. 7, and FIG. 9 is a worm driving unit of FIG. 7. It is a front view for demonstrating, FIG. 10 is a top view for demonstrating the elevator of FIG.

7 to 10, the ropeless elevator 400 includes a cabin unit 410, a lifting frame 420, a worm drive unit 430, and a worm support unit 470, and the ropeless elevator 400 may include The cabin 410 may move along the lifting space in the building by the interaction between the worm driving unit 430 and the worm supporting unit 470. The ropeless elevator 400 may further include an independent controller 480, an air conditioner 485, a wireless communication module 490, and the like, and may smoothly drive and control the ropeless elevator 400.

The worm drive unit 430 includes a worm gear body 440 having a wormgear shape, and teeth 442 are formed on an outer surface of the worm gear body 440. The worm gear body 440 includes a rotating shaft arranged side by side in the ropeless elevator 400 in a traveling direction, and is rotatably mounted about the rotating shaft. The worm support portion 470 is provided in the lifting space corresponding to the teeth 442 of the worm gear body 440. In the present embodiment, the teeth 442 and the worm support portion 470 of the worm gear body 440 have the same polarity. Permanent magnets or electromagnets may be provided.

The worm driving unit 430 rotates the worm gear body 440 in the elevating device, and the tooth surface of the worm gear body 440 may receive a force that can rise without being in close contact with each other by the repulsive force with the worm support 470. As the worm gear body 440 rotates, it may rise or fall as if it slides together with the cabin part 410 in the injured state on the worm support part 470.

Since the cabin part 410 can be elevated using the worm drive part 430, it does not use the conventional rope or wire, and it does not need to install a hoist or a machine room on the uppermost floor. That is, using the worm driving unit 430 installed on the upper or lower portion of each room portion 410, it is possible to switch the rotation of the worm driving unit 430 to the vertical movement of the room portion 410 without depending on the rope. .

Therefore, the drive system of the ropeless elevator 400 is simplified, and by eliminating the rope, it is possible to eliminate the burden on the weight of the huge rope when applied to the skyscraper. In addition, the structural rope can be smoothly moved and the burden on the balance weight can be eliminated.

The rotation can be converted to the position energy without substantial loss of energy. On the contrary, the desired speed and control can be achieved with a minimum energy when the motor is descended. In the case of the initial acceleration, the presently developed drive motor can provide sufficient maneuvering power, and the initial acceleration, the low speed maintenance, the high speed maintenance and the deceleration can be easily performed through the motor control.

In response to one rotation of the worm gear body 440, the pitch of the support tooth of the worm support part 470 may be moved. Therefore, assuming that the pitch of the worm support part 470 is about 25 to 50 cm, the worm driving part 430 can sufficiently provide a speed of about 500 to 1000 m / min with only about 2000 rpm of rotation. That is, it is possible to easily implement an ultra-high speed elevator.

It is possible to easily implement a twin system that can move two or more cabin units 410 in one lifting space. Since no rope is used, two or more cabin parts 410 may be freely arranged in the same space, and the ropeless elevator 400 may be installed by using a wireless communication module 490 mounted on the mutual cabin part 410. Control can be easily performed. In particular, since there are no obstacles in the lifting space, the use of the wireless communication module 490 may be easier.

The ropeless elevator 400 according to the present exemplary embodiment may prevent an accident in which the cabin part 410 falls down forcefully even when a worst-case situation occurs in which power is cut off or the braking device is disabled. In the characteristic of the worm gear, even if the motor gear is descending, the motor can be smoothly decelerated smoothly as well as physically stopped if the motor is stopped. Even if the motor continues to descend, the descending speed is maintained at a safe low speed, Can be safely protected.

The cabin 410 may be stably moved in the lifting space by the lifting frame 420, and the lifting frame 420 may be guided to move without shaking in the lifting space by using the roller 424 located at the corner. have. Of course, the magnetic guide using a magnetic force in addition to the roller may control the shaking of the lifting frame 420.

In this embodiment, the worm driving unit 430 is mounted on the support frame 426, the room portion 410 and the lifting frame 420 may move together by the worm driving unit 430. Of course, a rail having a T-shaped cross section parallel to the movement path of the compartment 410 may be formed as in the related art, and the compartment 410 may be moved along the T-shaped rail.

The lifting frame 420 protecting the cabin part 410 may be accommodated by moving together in the above-described switch frame 300, and the switch frame 300 also corresponds to the shape of the lifting frame 420 by rollers and rails. Can be provided.

The worm driving unit 430 may mount the drive motor and the transmission to the outside, but in the present embodiment, the worm gear body 440 may include a motor structure capable of generating a driving force therein. To this end, the worm gear body 440 may be provided in a hollow form, and both ends of the worm gear body 440 may be rotatably mounted using a bearing on a rotation shaft. In addition, it may include a stator 452 fixed to the rotating shaft for driving and a rotor 454 mounted on the inner surface of the worm gear body 440, the stator 452 and the rotor 454 of the magnet and coil Combinations, coils and coil combinations, and the like.

The tooth surface of the worm gear body 440 is supported by the roller 475 exposed as the upper surface of the support structure 472, and rides on the roller 475 of the worm support part 470 as the worm gear body 440 rotates. 410 may slide up or down as if sliding.

The worm support 470 may include magnets or electromagnets disposed at equal intervals, and rollers may be provided at or around the contact surface of the worm support 470. The roller may prevent direct contact with the tooth surface of the worm support part 470 and the worm gear body, and may prevent the magnet structure from being damaged at the mutual contact surface.

11 is a cross-sectional view for explaining the interior of the worm drive unit.

Referring to FIG. 11, the driving module 450 formed in the worm gear body 440 includes two pairs of stators and rotors. To this end, the worm gear body 440 may be provided in a hollow form. In the upper portion of the worm gear body 440, a coil stator 452 and a coil rotor 454 are provided as a coil-coil combination, and a coil stator 456 and a magnet rotor are provided as a coil-magnet combination. The former 458 may be provided. Of course, the coil rotor 454 may also be provided in the form of an iron core rather than a coil.

Two or more pairs of stators and rotors may be used to appropriately adjust the rotational torque and the rotational speed, and induction power generation may be expected due to the rotation of the worm gear body 440. For example, when the landing gear falls, the relative rotation of the stator and the rotor can generate power, and energy can be efficiently used while repeating the ascending and descending.

12 is a view for explaining a worm driving unit according to another embodiment of the present invention.

Referring to FIG. 12, when the electromagnet is used, power may be applied to the coil module 543 on all teeth of all the worm gear bodies 540. However, this results in excessive electric field generation and excessive power consumption. Can be imported.

Thus, as shown, the coil module 543 located vertically on the tooth surface of the worm is partially interlocked, and power can be selectively applied to the electromagnet coil module 543 located on the vertical tooth surface. At this time, the lower connection terminal 562 may be sequentially connected to or disconnected from the power source according to the rotation of the worm gear body.

The connection terminal 562 connected to the power supply may be one or a plurality, and the angle range to which the power is applied may also be changed to various conditions such as being disposed at an angle of 10 to 30 to 40 degrees.

Of course, the electromagnet coil may be mounted in the worm support in relation to the portion to which the power is applied, and power may be supplied corresponding to a specific position where the elevator is located, instead of supplying power to the supports in all the lifting spaces. For example, the power may be applied to the worm support part 575 from the upper and lower floors immediately above the point at which the elevator passes, and the power may be applied by changing the level up to two floors below.

FIG. 13 is a schematic view illustrating a recirculating elevator system according to still another embodiment of the present invention.
