Description

Three Way Elevator Circulation System

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 (Elevator) is a device for transporting people or cargo vertically and vertically in response to gravity, and is used throughout high-rise buildings as well as low-rise buildings. In general, the elevator has a rope type elevator and a hydraulic elevator according to the driving method, in addition, there is a screw type, rack and pinion type, and a ropeless elevator using a linear motor instead of a hoist.

The rope elevator has a machine room for driving the elevator on the top floor, and a traction machine of the machine room moves the cabin up and down by connecting a car and a balance weight with a rope. Such a machine room may be detrimental to the building for several reasons, such as height limitations. Recently, high-performance elevators have emerged along with the construction boom of high-rise buildings, and high-speed elevators moving at a high speed of about 60 km / h (1000 m / min) or more have been developed. There are also double-deck elevators that have two elevators connected up and down to improve their transport capacity, and there are twin elevators that operate two elevators independently in one elevator aisle.

Skyscrapers require faster moving elevators to facilitate vertical copper transportation. To speed up an elevator, tension is applied to the wires that is proportional to the square of the speed, and the higher the elevator, the greater the tension. Therefore, the cross section of the rope becomes larger and the weight of the rope increases. In addition, because the length of the rope must be as long as the long distance of the skyscraper, the rope must be thicker by increasing the weight of the rope itself. In skyscrapers, the rope may eventually be heavier than the elevator cabin.

In fact, among the high-speed elevators installed in the Buzz Dubai Building, the rope weighs only 20 tons (t). In addition, counterweights and chain weights are added, so accelerating the elevator at high speed requires an extraordinary amount of power. After all, the elevator, which is too heavy due to the rope, must be accelerated at a very high speed, and therefore the motor of the hoist must also be provided with a significantly larger capacity than a general motor.

In addition, when the rope is lengthened by several hundred meters or more, it becomes difficult to stop at the correct position because the length of the rope varies according to the degree of wear of the rope or the temperature change. Therefore, the characteristics of the wire rope become more difficult and the control method thereof becomes complicated.

Conventional screw-type elevators utilize a structure in which a long post that is threaded is erected and a sleeve corresponding to the nut is installed in the cabin. In a screw-type elevator, the cabin is moved up and down by rotating the prop, so that it is used in a small simple elevator or when the fluid is difficult to move.

Already, skyscrapers of more than 100 stories are expected to use ropeless elevators instead of conventional rope elevators. US Patent No. 5234079 discloses an elevator using a linear motor. However, since these linear elevators move in the air without a rope, the safety device must be firmly tripled and tripled, and there is no physical contact, which means that horizontal and vertical movement is possible, but failed to control safely. It is difficult to overcome because there are not many factors to solve such as safety and economics.

The world's elevator industry is experiencing an exponentially heavy burden of speeding up wire rope-type excessive rope weights and huge hoistings in skyscrapers, which is a dilemma and a new elevator to break through. Together we look forward to the emergence of the drive system.

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 a three way elevator circulating system capable of efficiently circulating an elevator using a ropeless elevator.

The present invention provides an elevator circulation system that can increase the sale profit and increase the value of the building by reducing the area ratio occupied by the elevator to increase the transport efficiency of the 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.

An object of the present invention is to provide an environment-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 first, second, and third hoisting spaces, a three-way elevator system using the first to third hoisting spaces to improve elevator operation efficiency may include: A plurality of ropeless elevators moving along the first to third lifting spaces, a switch space for the movement of the ropeless elevators between the first and third lifting spaces, and a central control unit for controlling the movement of the ropeless elevators; The controller may control a movement direction of the plurality of ropeless elevators circulating in the first to third lifting spaces according to the passenger transport plan.

Here, the passenger transport plan may mean a plan that is pre-programmed to efficiently transport passengers, and may be variously changed according to the day of the week, the time of departure / exit, the number of floor occupants, and the average number of floor visits. According to the passenger transport plan, the system of the present invention can adjust the circulation direction using the lifting space, the number of travel of the ropeless elevator, the travel interval, the travel speed, and the like.

In addition, a switch frame for transferring the ropeless elevator between the first to the third lifting space by the central control unit may be disposed in 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 or three units in one hoisting space, but they are complicated and have many technical limitations.

On the other hand, a ropeless elevator can implement a system in which two or more elevators are arranged in one accommodation space without using a rope.

In addition, a spare space is further provided next to the switch spaces of the first to third lifting spaces so that the switch frame can wait in the spare space, and according to the command of the central control unit according to the density of the elevator in the first to third lifting spaces. The elevator waiting in the spare space may be introduced into any one of the first to third lifting spaces, or the elevator may be recovered to any one of the first to third lifting spaces.

The density may vary depending on the number or distance of elevators according to the number of passengers or the main direction of travel of the passengers, and may also be affected by the speed of the elevator for adjusting the distance.

By forming switch spaces at the upper and lower ends of the first to third lifting spaces, and storing some ropeless elevators in the spare spaces next to them, only a part is used when it is busy, and when the passengers increase, the waiting elevator is moved to the operating elevator. Can be used by switching.

In addition, according to the number of waiting passengers, the waiting elevator waiting in the spare space can be put into any one of the first, second, third lifting space according to the command of the central control unit, and to measure the number of waiting passengers Additional count sensors may be provided on each floor of the building.

The ropeless elevators circulate through the first to third lifting spaces through the switch frame, but the elevators may be partially circulated or partially backed in the first to third lifting spaces.

In addition, the switch frame provided at the upper end of the first to the third lifting space is open at the bottom, it is possible to transfer the ropeless elevator entered from the lower to another lifting space, provided in the lower of the first to third lifting space The switch frame is opened at the top, it is possible to transfer the ropeless elevator entered from the top to another lifting space.

When circulating a plurality of ropeless elevators, the waiting elevator in the spare space can be put into the lifting space, and the operating elevator entering the spare space can be smoothly switched to the waiting elevator.

In addition, the switch frame can be rotated in the moving member for conveying it, while performing a straight line, horizontal, rotation, etc., it is possible to switch the door position by rotating the ropeless elevator through this rotation.

If the switch space is defined at both ends of the lifting space and the switch frame is installed in the switch space, the rope frame elevator can be moved from the switch space to another lifting space using the switch frame.

In the three-way elevator circulation system of the present invention, elevator switching between three lifting spaces is possible, and the elevator can be controlled to circulate up and down in each passage.

For example, when the first, second, and third hoisting spaces are arranged side by side, the ropeless elevators moving only up in the first hoisting space on the left and the third hoisting space on the right are continuously The second lifting space in the center continuously provides the ropeless elevators gathered in the first lifting space and the third lifting space to sequentially move downward only through the switch frame, thereby allowing ropes of the first lifting space and the second lifting space. The lease elevators circulate clockwise with each other, and the ropeless elevators of the second lifting space and the third lifting space may provide a three-way structure that circulates counterclockwise with each other.

In this case, since the passengers are lifted from the passages of the two lifting spaces of the first (left) and the third (right), an UP mode circulation system is provided, and particularly, it is effective when applied to work time.

In addition, the first lifting space on the left and the third lifting space on the right continuously provide ropeless elevators moving only DOWN, and the ropes gathered in the first lifting space and the third lifting space in the second lifting space in the center. By continuously providing the lease elevators only sequentially up through the switch frame, the ropeless elevators of the first hoisting space and the second hoisting space circulate counterclockwise with each other, and the ropes of the second hoisting space and the third hoisting space Lease elevators can provide a three-way structure that circulates clockwise with one another.

In this case, since the passengers are loaded in the passages of the two lifting spaces of the first (left) and the third (right), the DOWN mode circulation system is provided, and it is particularly effective when applied to lunchtime.

This has the effect of having four spaces in the case of using the built-in elevator circulating in the existing one direction. As a result, four aisles were reduced to three aisles by applying a three-way elevator circulation system. It is an efficient circulation system of elevators, which improves transportation efficiency and can reduce the area ratio of elevators in buildings.

In addition, when there are not many passengers, the operating elevator and the waiting elevator can be divided and partially operated, but the operating elevator does not circulate and moves only up and down like a conventional elevator and can transfer passengers.

Of course, when passengers increase or usage increases, ropeless elevators can be circulated through the aisle of the hoisting space, and some of the ropeless elevators may partially move in opposite directions to transfer the nearest passengers first.

The three-way elevator circulation system, in which a ropeless elevator circulates three hoisting spaces, can significantly reduce the waiting time for an elevator, and solve the problem of rope entanglement by not using the rope. In addition, a switch space or a spare space may be provided to adjust the distribution interval or the number of circulation elevators.

In addition, when a failure occurs in any one of the ropeless elevators that operate the first to third lifting spaces, the other ropeless elevators may operate to the upper and lower portions of the ropeless elevator where the failure occurs.

In addition, when the ropeless elevator having a failure is located in any one of the first to third lifting spaces, the ropeless elevator may operate in another lifting space where the failure of the ropeless elevator is not arranged.

In addition, the first to the third lifting space may have a non-pass elevator (PASS) section passing through each floor as it is.

In addition, two guide rails are disposed in each of the first to third lifting spaces, and two guide rails of the switch frame are also provided to coincide with the guide rails of the first to third lifting spaces. The third lifting space and the guide rail of the switch frame may be provided in a switch structure detachably detachable from each other.

In addition, the first to third lifting space includes a main guide for the transfer of the ropeless elevator, the switch frame further includes an extension guide that is detachably connected to the main guide for the transfer of the ropeless elevator, The elevator remains engaged with the extension guide and can be transported with the switch frame. For reference, the support teeth of the extension guides can be moved together with the switch frame.

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 the worm driving unit, the ropeless elevator may include a worm driving unit that moves along a lifting space, the cab driving unit moves along with the cabin, and the rotating shaft is parallel to the moving path of the cabin 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. . The worm drive unit alone can provide sufficient force for lifting, and assuming that the support values of the worm supports are arranged at intervals of about 40 cm, the worm gear body is about 400 m / min suitable for high speed elevators at a rotational speed of about 1000 rpm. Speed can be fully realized. Of course, the ultra high speed of 600 ~ 1500m / min can also be fully implemented. Basically, the cabin part can be vertically moved by the interaction between the worm drive unit and the worm support unit, and a rope as in the prior art is not used. Therefore, it can overcome the inefficiency according to the rope weight even when used in a high-rise building, and can use energy efficiently because it does not have to move tens of tons of rope.

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 magnetic levitation may be formed using a permanent magnet or an electromagnet or the like. Both rollers or magnetic levitation can move the worm surface as if it slides over the support teeth, which can move the cabin without noise or vibration, as well as increase wear life by preventing wear between parts.

The worm driving unit may include a worm gear body providing a tooth surface of the worm gear and a driving motor for rotating the worm gear body outside the worm gear body.

The worm driving unit may include a worm gear body providing a tooth surface of the worm gear and a driving unit for rotating the worm gear body in the worm gear body, and the driving unit corresponds to a stator and a stator mounted on a rotating shaft fixed to the cabin part. It includes a rotor mounted on the inner surface of the sieve, the worm gear body can rotate around the axis of rotation by the interaction of the stator and the rotor.

The central control unit collects at least one of the position, interval, and speed of the ropeless elevator and the switch frame through the sensor, checks the number of waiting passengers on each floor, and then checks at least one of the ropeless elevator's transport capacity, speed, and direction. The operation efficiency of the ropeless elevator can be improved by controlling the ropeless elevator and the switch frame through one of the calculation processes.

Two switch frames may be disposed at both ends of the first to third lifting spaces, respectively. Specifically, two switch frames may be disposed in the switch space above the first to third lifting spaces, and two switch frames may be disposed below the first to third lifting spaces.

The apparatus may further include a horizontal support coupled to the outer walls of the first to third lifting spaces and a roller moving horizontally on the horizontal support, and the switch frame may be coupled to the roller to move along the horizontal support. .

In addition, two horizontal supports are provided, and the switch frame is connected to an axis connecting the rollers moving on each horizontal support, and can move along the horizontal support safely to gravity.

Motor or hydraulic pressure may be used as the main force for driving the wheels, or the wheels may be driven by a robot arm.

The switch frame can also move to the magnetic levitation system.

In the present specification, a building may be understood as a concept including a connection structure connecting a building or a place, in addition to a general building, a tower, an apartment, and the like, and a lifting space is not limited to only a closed space in the building, but partially. It may also include open spaces. In addition, the cabin part is to support and protect people and cargo, and transport, and may be provided in a temporarily closed or partially open state in the cabin part, and also the structure or rail for transferring the cabin part without shaking Can be provided.

The three-way elevator circulation system of the present invention is effective when applied to work time because it lifts passengers in two passages by the UP mode circulation system of the three passages, on the contrary, two out of three by the DOWN mode circulation system Passengers are taken off the aisle, so it is effective when applied at lunchtime.

In addition, it is possible to reduce the passage of passengers and to improve the efficiency of passenger movement, while reducing the number of passages than the built-in elevator system requiring four passages, and contributing to increase the sales profit or building value by increasing the space utilization of limited buildings. have.

In addition, the lifting device that does not use ropes or wires can improve the inefficiency according to the huge weight of the ropes, and more skyscrapers or high-speed elevators can expect greater energy savings.

In addition, even in the worst case in which power is cut off or the braking device is disabled, accidents in which the cabin part falls down by force can be prevented. 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, in the case of using a worm gear-type driving unit, it is possible to move the cabin part with very little energy when descending, and to reuse and accumulate energy by using induction power generation or a hybrid system of an automobile. 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.

When a conventional rope elevator is applied to a high-rise building, the length and number of ropes increase, and as the speed increases, complicated and expensive advanced technologies should be applied. It is possible to cope with it sufficiently and installation cost and burden does not increase much even if it continues to rise. 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.

In addition, according to the three-way elevator circulation system of the present invention, there is no need for the machine room on the top floor, thereby increasing the utilization of the building, it is possible to design freely 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 the inside of the worm gear body. When the drive motor is applied to the inside of the worm gear body and the drive motor is a gearless motor, and the housing is formed as a worm gear body, the weight of the worm drive unit While significantly reducing the volume and volume, the output and efficiency of the worm drive can be increased.

In addition, according to the three-way elevator circulation system of the present invention, it is not necessary to arrange the rope in the elevating passage, so that several cabin units in one elevating passage can be continuously operated at regular intervals like trains running on the rail. Therefore, the weight of the hoistway is greatly reduced, and there is no restriction due to the rope, so there is no limitation of the stroke length, and the inconvenience of having to replace the rope periodically can be eliminated.

In addition, since the worm drive unit and the cabin part move independently along the arrangement of the worm support, the cabin part may move in an inclined direction rather than in a vertical direction, or may move along a curved path rather than a straight line. In addition, horizontal driving may be implemented.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments. For reference, in the present description, the same numbers refer to substantially the same elements, and may be described by referring to the contents described in the other drawings under these rules, and the contents determined to be obvious to those skilled in the art or repeated may be omitted.

1 is applied to a three-way elevator circulation system according to an embodiment of the present invention in a building, and shows various modes of operation thereof.

More than one three-way elevator circulation system may be provided within a building and may be used in combination with a conventional linear reciprocating elevator system that is not circular.

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 can be moved together in one hoisting space, and since they move only in one direction, users can quickly move between floors by minimizing waiting time.

The three-way elevator circulation system is operated in three lifting spaces, the switch space 40 is disposed in the upper and lower ends of each lifting space.

FIG. 1 (a) shows a general reciprocating mode in which the ropeless elevator 1 moves up and down in the first to

third lifting spaces

10, 20, and 30. In FIG. The case where the ropeless elevator operates upwards in the left and right lifting spaces downward, and the case where the ropeless elevator operates upwards in the central lifting space and downward in the left and right lifting spaces in FIG. 1C. For reference, the three lifting spaces of the present embodiment are arranged in a line, the three lifting passages may be arranged in various ways in consideration of the space efficiency of the building, such as arranged in a triangle or bent when viewed from the top.

In FIG. 2, when the number of passengers increases, the ropeless elevator moves only upward in both first and third lifting spaces except the second lifting space in the center, and the ropeless elevator moves only downward in the central lifting space. The circulation driving mode is illustrated, and in the switch spaces provided above and below each lifting space, the ropeless elevator may be transferred to different lifting spaces by the switch frame.

That is, the elevators circulate clockwise in the first and second lift spaces, and the elevators circulate counterclockwise in the second and third lift spaces. This is effective when applied to rush hours because passengers are lifted from two passages of the first and third lifting spaces among the three passages.

Specifically, Figure 2 (a) in the general reciprocating mode, the ropeless elevator is reciprocating up and down in three passages, because there are not a lot of passengers, 1, 3, 6, 9 ropeless elevators are waiting in the switch space. When the number of passengers increases again, as shown in FIGS. 2 (b) and 2 (c), all the elevators are operated, and the ropeless elevators have different lifting spaces by switch frames in the switch spaces provided above and below the respective lifting spaces. It can be circulated while feeding.

FIG. 3 is a view for explaining a circular driving mode suitable for an increase in number of passengers moving downward in each floor of a building, which is loaded with passengers in two passages of the first and third lifting spaces among the three passages. Therefore, it is effective when applied at lunch time.

Specifically, Figure 3 (a) in the general reciprocating mode, the ropeless elevator in the three passages up and down, but because there are not many passengers, 1, 3, 6, 9 ropeless elevators are waiting in the switch space. As passengers increase, as shown in Figs. 3 (b) and 3 (c), all elevators operate, but in the switch spaces provided above and below each hoisting space, the ropeless elevators move to different hoisting spaces by the switch frame. It is possible to circulate while transporting, continuously providing elevators moving only downwards in the first and third hoisting spaces, and moving elevators gathered in the first and third hoisting spaces only sequentially through the switch frame in the second hoisting space. Continuously provided, elevators of the first and second lifting spaces circulate counterclockwise with each other, and elevators of the second and third lifting spaces circulate clockwise with each other.

Here you can find the important value of the three-way elevator circulation system. The three-way elevator circulation system uses three passages selectively according to the direction of transportation of the passengers.In the case of the existing built-in elevators that circulate in one direction, four passages are required for the three-way elevator circulation system. Reduce to dog

4 and 5 show the operation of the three-way elevator circulation system in an emergency situation.

Referring to FIG. 4, when one of the ropeless elevators moving along the first to third lifting spaces fails, only the broken elevator is stopped, and other elevators partially reciprocate in the upper and lower parts of the broken elevator. Therefore, the two hoisting spaces, except the failed hoistway passages, can still operate with each other.

Specifically, FIG. 4 (a) shows a case in which the elevator is stopped in the middle passage, that is, in the middle of the second lifting space, and other elevators located above and below the stopped elevator may still operate, and the center passage may be It is still possible to cycle through the left and right passages.

4 (b) shows a case in which the elevator is stopped in the left passage, that is, the first lifting space, and the elevator may still circulate in the center and right passages.

4 (c) shows the case in which the elevator is stopped in the right passage, that is, the third lifting space, and the elevator can still circulate to the left and the central passages.

Referring to FIG. 5, a spare space is further provided next to the switch space of the first to third lifting spaces. Here, as in the switch space, the elevator can be transported while the switch frame moves, and in particular, when the central passage elevator fails, the switch frame can be held in the switch frame spare space to move non-stop between the right passage and the left passage. . The number of spare spaces can be changed according to the designer's intention in consideration of passengers using the building.

The spare space is a space in which the switch frame can be stayed, and can be usefully used for efficient operation according to necessity such as controlling the dispatch of an elevator cabin or emergency situation.

FIG. 6 shows that the ropeless elevators moving along the first to third hoisting spaces have a non-stop section so as to set a designated section so as not to stop on all floors and to quickly communicate with each other.

Specifically, two sets of three-way elevator circulation systems of the present invention are provided. In the A set on the left side having the first, second, and third hoisting spaces, eight elevators circulate from the seventh basement floor B7 to the thirtyth floor 30F, and B on the right side having the fourth, fifth, and sixth hoisting spaces. The set operates a pass section that operates directly on each floor from the seventh basement floor (B7) to the thirtieth floor (30F), and the elevator can circulate through each passage. And 30 floors can be used to transfer to different sets.

The central control unit of FIG. 7 controls the ropeless elevators moving along the first to third elevating spaces to operate smoothly, and the position, spacing, and speed of each elevator or switch frame in the central control unit are controlled through the sensors. After checking the number of waiting passengers on each floor, and calculating the transportation capacity, speed, direction, etc. of the elevator, and giving the optimum command to control the ropeless elevator and the switch frame, Improve operational efficiency.

FIG. 8 illustrates that the lower part of the switch frame provided at the upper end of the first to third lifting spaces is opened, and the ropeless elevator entering the lower portion is transferred to another lifting space. For reference, reference numerals for describing FIGS. 8 to 11 are shown in FIG. 8, and are omitted in other drawings.

The simulation that the switch frame of FIGS. 9 to 11 circulates in the upper part of the lifting space is a simulation in which a person who wants to move from the first floor to the upper floor flies during the rush hour, and carries passengers in two passages on the left and right sides. The lifting mode corresponds to the UP mode, and the upper and lower switch frames 50 of two upper and lower ropeless elevators are sequentially transferred to the central passage.

Specifically, referring to 1> 2> 3> 4 in FIG. 9, the elevator is transferred from the third lifting space 30 on the right side to the switch space 40 provided at an upper portion thereof, and is switched by the switch frame disposed in the switch space. It moves to the 2nd lifting space 20 of the center.

Referring to 5> 6> 7> 8 in FIG. 10, the elevator transported together with the switch frame to the center second lifting space is transferred downward through the second lifting space. In addition, another elevator is transported from the leftmost first elevating space 10 and moved to the center second elevating space by a switch frame disposed in the switch space above the first elevating space.

Referring to 9> 10> 11> 12 in FIG. 11, an elevator transported together with the switch frame from the first lifting space to the switch space above the second lifting space moves downward to the central passage.

That is, in the left and right lifting spaces, the elevators move upwards and move downward through the central lifting spaces.

Meanwhile, FIG. 12 illustrates a process in which an upper portion of the switch frame provided at the lower ends of the first to third lifting spaces is opened and the ropeless elevator entering the upper portion is transferred to another lifting space.

13 and 14 show a simulation in which the switch frame circulates in the lower part of the lifting space in the UP mode, and lifts passengers in two left and right aisles, and the two lower left and right switch frames in the center aisle Ropeless elevators are sequentially transferred to the hoistway passage.

Referring to FIG. 19 for a while, a spare space 60 is further provided next to the switch space 40 of the first to third lifting spaces so that the switch frame 50 can stand by in the spare space. Spare space is a space where the switch frame can stay, which is necessary for efficient operation as required by the circulation system or emergency situation by the circulation system.

According to the density of the operating elevators in the first to third lifting spaces, the standby elevator waiting in the spare space is input to the first to third lifting spaces by the command of the central control unit, or the operating elevators of the first to the third lifting spaces. It can be recovered to the spare space.

Referring to FIG. 8 for a moment, the first to third lifting spaces include a main guide 70 for conveying a ropeless elevator, and the switch frame is extended to be detachably connected to the main guide for conveying a ropeless elevator. It further comprises a guide (80). And, the ropeless elevator is to be transported with the switch frame while maintaining the state bound with the extension guide.

15 and 16 are structural diagrams of a worm maglev elevator which is a ropeless elevator. Referring to FIGS. 15 and 16, the ropeless elevator moves along with the cabin part 2 and the cabin part moving along the first to third lifting spaces, and a worm driving part 90 whose rotation axis is parallel to the moving path of the cabin part. It includes, the worm drive motor of the worm drive unit 90 can be powered by the battery 96, the main guide and the extension guide to the interval of the tooth 92 of the worm gear body of the worm drive unit 90 A worm support portion 70 includes a plurality of support teeth 72 formed to correspond to the teeth of the worm drive portion, and the worm drive portion and the worm support portion maintain low resistance contact. In addition, the worm drive unit and the worm support unit can maintain the low resistance contact by using the rolling contact or magnetic levitation. The guide rail holder 4 fixed to the compartment 2 is bound to the guide rail 52 so that the compartment may be guided by the guide rail.

The worm drive unit 90 may include a worm gear body providing a tooth surface of the worm gear and a driving motor for rotating the worm gear body.

Referring to the detailed view of the worm driving unit of FIG. 17, the worm driving unit includes a worm gear body providing a tooth surface of the worm gear and a driving unit for rotating the worm gear body inside the worm gear body, and the driving unit includes a rotating shaft fixed to the cabin ( And a rotor 99 mounted on the inner surface of the worm gear body corresponding to the stator, and the worm gear body can rotate around the rotation axis by the interaction of the stator and the rotor.

The ropeless elevator includes a cabin part, a lifting frame, a worm drive part and a worm support part, and the cabin part of the ropeless elevator can move along a lifting space in a building by interaction between the worm drive part and the worm support part. The ropeless elevator may further include an independent control unit, an air conditioner, a wireless communication module, and the like, and may smoothly drive and control the ropeless elevator. The worm driving unit includes a worm gear body having a wormgear shape, and teeth are formed on an outer surface of the worm gear body. The worm gear body includes a rotating shaft arranged side by side in the ropeless elevator and is rotatably mounted about the rotating shaft. The worm support portion is provided in the lifting space corresponding to the teeth of the worm gear body. In the present embodiment, the tooth and the worm support tooth of the worm gear body may be provided with permanent magnets or

electromagnets

91 and 93 of the same polarity.

The worm drive unit rotates the worm gear body in the elevating device, and the tooth surface of the worm gear body may receive a force that can rise without being in close contact with each other by the repulsive force with the worm support unit. As the worm gear body rotates, it can rise or descend as if it slides together with the cabin in a magnetically floating state on the worm support.

Since the compartment can be elevated using a worm drive, it does not use a conventional rope or wire, and there is no need to install a hoist or machine room on the top floor. That is, by using a worm driving unit installed in the upper or lower portion of each compartment, it is possible to switch the rotation of the worm drive to the vertical movement of the compartment without depending on the rope.

By eliminating the rope, the weight of the huge rope can be eliminated when applied to skyscrapers. In addition, the structure can also remove the burden on the smooth movement of the rope and counterweight hypothesis.

In terms of efficiency, it rotates by magnetic levitation rather than friction, so that rotation can be converted into potential energy without substantially losing energy. On the contrary, when descending, desired speed and control can be executed with minimum energy. In the case of initial acceleration, the presently developed drive motor can provide sufficient maneuverability, and the initial control, low speed maintenance, high speed maintenance and deceleration can be easily performed through motor control.

In response to one rotation of the worm gear body, the support value of the worm support portion may move by one pitch. Therefore, assuming that the pitch of the worm support is about 25-50 cm, the worm drive can provide a sufficient speed of about 500-1000 m / min with only about 2000 rpm of rotation. That is, it is possible to easily implement an ultra-high speed elevator.

It is easy to implement a twin system that can move two or more cabins in one hoisting space, and since two ropes are not used, two or more cabins can be freely arranged in the same space. The control of the ropeless elevator can be easily performed by using a wireless communication module mounted on the mutual cabin unit. In particular, since there are no obstacles in the lifting space, the use of the wireless communication module may be easier.

The ropeless elevator according to the present embodiment can prevent an accident that the cabin part falls down by force even when a worst-case situation occurs in which power is cut off or the braking device is disabled. Due to the characteristics of the worm gear, even if it is descending, if the motor stops, the lowering of the motor can be smoothly decelerated, as well as physically stopped.Even if the lowering continues, the descending speed is maintained at a safe low speed. Can be protected safely.

The cabin part can be stably moved in the lifting space by the lifting frame, and the guide rail holder of the lifting frame surrounds the guide rail safely. Since the roller of the guide rail holder maintains a low resistance friction state with the guide rail, the guide rail holder may be guided to move without shaking in the lifting space. Of course, in addition to the roller, the magnetic guide using magnetic force may control the shaking by the lifting frame.

The worm gear body may be provided in a hollow form, and both ends of the worm gear body may be rotatably mounted using the bearing 95 on the rotating shaft. In addition, it may include a stator fixed to the rotating shaft for driving and a rotor mounted on the inner surface of the worm gear body, the stator and the rotor may be provided through a combination of a magnet and a coil, a combination of a coil and a coil.

The tooth surface of the worm gear body is supported by the roller exposed to the upper surface of the support structure, and as the worm gear body rotates, it can rise or descend as if it slides together with the cabin part by the roller of the worm support unit.

The worm support includes magnets or electromagnets arranged at equal intervals, and a roller may be provided at or around the contact surface of the worm support. The roller may prevent direct contact with the tooth surface of the worm support and the worm gear body, and may prevent the magnet structure from being damaged at the mutual contact surface even when the power is cut off.

The drive motor formed inside the worm gear body may include two pairs of stators and rotors. For this purpose, the worm gear body may be provided in a hollow form. Inside the worm gear body, a coil stator and a coil rotor may be provided as a combination of coils and coils, and a coil stator and a magnet rotor may be provided as a combination of coils and magnets. Of course, the coil rotor may also be provided in the form of an iron core rather than a coil.

Two or more pairs of stators and rotors can be used to appropriately adjust the rotational torque and rotational speed, and induction power generation can be expected due to the rotation of the worm gear body. For example, when the elevating device is lowered, power generation may be caused in the relative rotation of the stator and the rotor, and the energy may be efficiently used while repeating the elevating.

FIG. 18 shows that two switch frames 50 are respectively provided in the upper and lower portions of the first to third lifting space elevator passages, and guide rails are provided for each passage of the first to

third lifting spaces

10, 20, and 30. Two (12, 22, 32) are provided, and the guide rails 52 of the switch frame are also two so that the guide rails of the passage and the guide rails of the switch frame can be parallel to each other so that they can be separated from each other. It shows that the structure of the switch state is connected and detachable. The two units can be economical and space-saving as they can simplify the structure while ensuring safety.

The support frame 82 of the extension guide 80 is coupled to the switch frame 50 to allow the support guide of the extension guide to move together when the switch frame moves, which is a structural source of the risk that the ropeless elevator falls down. It is an important part of the blockade.

In addition, a structure in which the switch frame is hung on the horizontal support 110 which is coupled to and supported by the outer wall of the lifting space so that the switch frame is secured against gravity also increases safety.

In the structure in which the switch frame is hung on the horizontal support, two horizontal supports are provided and allow the wheels (including the rollers) to roll on the horizontal support, and may be provided in a structure in which the switch frame is hung on the wheel shaft.

In addition, it is possible to use the motor or hydraulic pressure as a driving force for the wheels, or to use the motor and hydraulic pressure in parallel, and the main wheel for driving the wheels on the upper side of the horizontal support to prevent shaking during the horizontal movement and quick and precise and smooth control. In addition to the power, at least one or more auxiliary feeders using levers, wires, chains, belts, magnetic levitations, or the like may be further provided on at least one portion of the switch frame.

Using motors or hydraulics as the power to drive the wheels can be driven on the wheel shaft through levers, wires, belts, chains, etc., and can also be moved to the magnetic levitation system in place of the wheels.

20 illustrates that the switch frame can be applied to the two-way elevator circulation system in the three-way elevator circulation system, and the elevator can be circulated by the switch frame in two lifting spaces.

In addition, as shown in FIG. 21, driving the wheel shaft with the robot arm 120 serves to control the switch frame quickly, precisely and smoothly while ensuring safety of the switch frame.
