Description

{THREE WAY ELEVATOR CIRCULATING SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator or other lifting apparatus, and more particularly, to an elevator system capable of conveying a passenger or a cargo while circulating a car of an elevator without a wire or a rope.

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, the rope could eventually be much heavier than the elevator's room.

In fact, the rope weighs only 20 tons (t) of the ultra-high-speed elevators installed in the Burj Dubai building. In addition, the weight of the balance or chain is added up to the weight of the chain, so it requires a surprisingly large power to accelerate the elevator at 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 and vertically without physical contact, but fails to securely control it. Safety and economic efficiency are very few to overcome.

The elevator industry in the world is struggling with the exponential increase in speed with high rope weights and huge hoisting machines in skyscrapers, which is why we are in a dilemma, Together, they are looking forward to the emergence of the drive system.

Also, although a ropless elevator using a worm gear-type driving body is disclosed in U.S. Patent Application Publication No. 2002-0125075 and Korean Patent Registration No. 10-1035068, only the contents which can be moved only up and down are disclosed, It leaves room for.

The present invention provides a three way elevator circulating system capable of efficiently circulating an elevator using a ropless elevator.

The present invention provides an elevator circulation system capable of increasing the efficiency of transportation of an elevator and reducing the area occupied by the elevator, thereby increasing the sales profit of the building and increasing the value of the building.

The present invention provides an elevator system using a worm elevator capable of safely supporting a passenger compartment using physical contact and capable of increasing elevator efficiency without friction, and capable of easily circulating the worm elevator.

It is an object of the present invention to provide an environmentally friendly elevator system which is highly feasible and can expect energy recovery effect.

According to an exemplary embodiment of the present invention, in a structure including first, second, and third lift spaces, a three-way elevator system for improving elevator operation efficiency using first to third lift zones, A plurality of ropeless elevators moving along the first to third lift spaces, a switch space for moving the ropeless elevator between the first to third lift zones, and a central control unit for controlling the movement of the ropeless elevator, The control unit may control the moving directions of the plurality of loomless elevators circulating through the first to third elevated spaces according to the passenger transportation plan.

Here, the passenger transportation plan may mean a program previously programmed to efficiently transfer passengers, and may be variously changed depending on the day of the week, departure / arrival times, the number of residents by floor, the average number of visitors per floor, and the like. According to the passenger transportation plan, the system of the present invention can control the circulation direction using the ascending / descending space, the number of operations of the ropless elevator, the operation interval, and the traveling speed.

Further, the switch space may be provided with a switch frame for transferring the ropless elevator between the first and third lifting spaces by the central control unit.

In the case of a rope-type elevator, due to the structural limitation provided by the rope, the elevator has to move up and down, and only one elevator can move in one elevating space. There are, of course, technologies that move two or three cars in a single lift, but they are complicated and subject to a number of technical constraints.

On the other hand, in the case of the ropless elevator, it is possible to implement a system in which two or more elevators are arranged in one accommodation space without using ropes.

In addition, a spare space may be provided beside the switch spaces of the first to third lift spaces to allow the switch frame to stand in the spare space. Depending on the density of the elevator in the first to third lift spaces, The elevator waiting in the spare space may be put into one of the first to third elevating spaces or the elevator may be recovered in any one of the first to third elevating spaces.

The density may vary depending on the number of passengers or the number or spacing of elevators depending on the passenger's main direction of travel, and may also be influenced by the speed of the elevator for adjusting the spacing.

A switch space is formed at both upper and lower ends of the first to third lifting and lowering spaces and a part of the ropless elevator is stored in a spare space beside the first and third lifting and lowering spaces. You can switch and use.

In addition, depending on the number of waiting passengers, the waiting elevator waiting in the spare space can be put into any one of the first, second, and third ascending / descending spaces in accordance with the command of the central control unit. In order to measure the number of waiting passengers A count sensor may be further provided on each floor of the building.

The elevator can be partially circulated or partially reversed in the first to third elevated spaces by loopless elevators circulating through the switch frame through the first to third elevated spaces.

Further, the switch frame provided at the upper end of the first to third lifting and lowering spaces may be opened at the bottom, and the ropless elevator that has entered from the bottom may be transferred to another elevating space, and may be provided at the lower end of the first to third elevating and lowering spaces The upper part of the switch frame is opened and the ropless elevator that has entered from above can be transferred to another elevating space.

When the plurality of ropeless elevators are circulated, the waiting elevator in the spare space can be put into the elevating space, and the traveling elevator that has entered the spare space can be smoothly switched to the waiting elevator.

In addition, the switch frame can be rotated in a moving member that transports the switch frame while being straight, horizontally, or the like, and the position of the door can be changed by rotating the ropeless elevator through the rotation.

If a switch space is defined at both ends of the upper and lower ends of the ascending / descending space and a switch frame is provided in the switch space, the ropeless elevator can be moved to another ascending / descending space in the switch space using the switch frame.

In the three-way elevator circulation system according to the present invention, the elevator can be switched between the three elevating spaces, and the elevator can be controlled to circulate up and down in each of the passages.

For example, when the first, second, and third elevation spaces are arranged in a row in this order, in the first elevation space on the left side and the third elevation space on the right side, the ropeless elevators moving only UP And the ropeless elevators gathered in the first elevating space and the third elevating and lowering space are successively moved downward sequentially through the switch frame in the central second elevating and lowering space, The lease elevators can circulate clockwise to each other and the ropeless elevators in the second elevating space and the third elevating space can provide a three-way structure that circulates counterclockwise to each other.

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

In the first elevating space on the left side and the third elevating space on the right side, ropless elevators moving only downward are continuously provided. In the second elevating space in the center, ropes gathered in the first elevating space and the third elevating space The lift elevators are successively moved upward in sequence through the switch frame so that the ropeless elevators in the first lift space and the second lift space circulate counterclockwise to each other and the ropes of the ropes in the second lift space and the third lift space The lease elevators can provide a three-way structure that circulates clockwise to each other.

In this case, since the passengers are carried in the passages of the first (left) and the third (right) elevation spaces, a DOWN mode circulation system is provided, and this is particularly effective when applied to lunch time.

This shows the effect of having four idle spaces when using a built-in elevator that circulates in one direction. As a result, the need for four passageways is reduced to three passageways by applying a three-way elevator circulation system. This is an efficient circulation system of the elevator, which improves the transportation efficiency and reduces the area occupied by the elevator in the building.

When the passenger is in a time zone with few passengers, the elevator can be operated partly by separating the elevator from the elevator. The elevator can be partially moved up and down like a conventional elevator without circulating the elevator.

Of course, if the passenger increases or the usage increases, the ropless elevators may cause the passage of the elevated space to circulate, and some of the ropless elevators may move partially in the opposite direction to transfer the nearest passenger first.

The three-way elevator circulation system in which the ropley elevator circulates through three elevating spaces can significantly reduce the elevator waiting time and can solve the problem of rope tangling by not using the rope. In addition, a switch space or a spare space can be provided to control the dispensing interval or quantity of the circulating elevator.

Further, when any one of the ropless elevators operating in the first to third elevated spaces occurs, the other roples elevator can be operated to the upper and lower portions of the ropless elevator in which the failure occurs.

Further, when the ropless elevator in which the failure occurs in any one of the first to third lift spaces is located, the ropeless elevator can be operated in another elevated space where the ropless elevator in which the failure occurs is not disposed.

Also, the first to third lift spaces may have a pass section in which the ropless elevators pass through the respective layers as they are.

In addition, two guide rails are provided in the first to third lift spaces, and two guide rails of the switch frame are provided so as to coincide with the guide rails of the first to third lift spaces. The third lifting space and the guide rail of the switch frame may be provided with a detachably detachable switch structure.

Further, the first to third lift spaces include a main guide for feeding the ropless elevator, and the switch frame further includes an extension guide detachably connected to the main guide for conveying the ropless elevator, The elevator can be transported together with the switch frame while remaining in engagement with the extension guide. For reference, the support of the extension guide can be coupled with the switch frame and moved together.

The ropless elevator can be provided with various types of elevators. For example, it may be manufactured by a method using a linear motor or a method using a worm drive unit described later. In the case of a system using a worm driving unit, the ropless elevator may include a worm driving unit that moves together with the passenger compartment and the passenger compartment moving along the up / down space, and the rotating shaft is parallel to the moving path of the passenger compartment.

The worm driving unit includes a wormgear body in the form of a worm gear, and the worm gear body is capable of providing a force for lifting and lowering while being meshed with the supporting teeth of worm supporting parts disposed at regular intervals . Assuming that the worm driving part itself can sufficiently provide the force necessary for lifting and lowering, and assuming that the supporting values of the worm supporting parts are arranged at intervals of about 40 cm, the worm gear body is rotated at a speed of about 1000 rpm at a speed of about 400 m / min The speed can be fully realized. 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 worm surface move slidably on the support teeth in both the roller and the magnetic levitation, it is possible to move the room part without noise or vibration, and also to prevent the abrasion between parts, thereby increasing the service life of the parts.

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

The worm driving unit may include a worm gear body for providing a tooth surface of the worm gear and a driving unit for rotating the worm gear body inside the worm gear body. The driving unit may include a stator mounted on a rotary shaft fixed to the cabin, And the worm gear body can rotate around the rotation axis by the interaction of the stator and the rotor.

The central control unit collects at least one of the position, the spacing, and the speed of the ropiness elevator and the switch frame through the sensor, checks the number of passengers in each floor and then determines at least one of the transport capacity, The operation efficiency of the ropless elevator can be improved by controlling the ropless elevator and the switch frame through any one of the calculation processes.

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

The apparatus may further include a horizontal support and horizontally supported rollers coupled to the outer walls of the first to third lift spaces, and the switch frame may be coupled to the rollers to move along the horizontal supports .

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

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

In addition, the switch frame can move to the levitated system.

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. In addition, the room part is for supporting and protecting the person, the cargo, and the like, and may be provided in a state in which the space in the room part is temporarily closed or partially opened, and a structure or a rail for conveying the room part smoothly Can be provided.

The three-way elevator circulation system of the present invention is effective when it is applied to the working time because it raises passengers in two passages by the UP mode circulation system among the three passages, and conversely, two of three It is effective when it is applied at lunch time because passengers are carried in passageway.

In addition, it is possible to increase the passenger transportation efficiency to be equal to or higher than that of a conventional elevator system requiring a conventional passageway while reducing one passageway, and to improve the space utilization of limited buildings, have.

In addition, the lift device without rope or wire can improve the inefficiency according to the massive weight of the rope, and a higher energy saving effect can be expected for a skyscraper or a super-high-speed elevator.

In addition, even when a worst situation occurs in which the power is cut off or the braking device becomes inoperable, it is possible to prevent an accident that the passenger compartment falls helplessly. Due to the characteristics of the worm gear, even if it is descending, if the motor stops, the downward smoothly decelerates smoothly, and it can physically stop. Even if it moves, it keeps descending speed at low speed, 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.

Further, when the worm gear type driving unit is used, it is possible to move the room part with a very small energy at the time of descending, and energy can be reused and stored by using induction power generation or hybrid system of automobile. Particularly, as described above, when an external power supply is shut down due to an accident, power can be generated from the rotation of the worm driving part due to the fall, and at least the control in the emergency situation, the minimum communication, Magnetic force relief and the like. Particularly, when magnetic levitation is used for low resistance contact, the best effect can be obtained with a simple structure.

When a rope elevator is applied to a high-rise building, the rope length and the number of ropes increase, and the higher the speed, the more complicated and expensive the advanced technologies must be applied. However, the present invention using the worm- And the installation cost and the burden do not increase so much even if the installation progresses to a higher level. In addition, it is very easy to control low speed, high speed, acceleration, deceleration, etc. by adjusting the rotational speed of the worm drive.

Further, according to the three-way elevator circulation system of the present invention, since the machine room of the uppermost layer is not required, utilization of the building can be increased, and design free from limitation of the height of the building is possible. In addition, in the worm driving part, the driving motor can be applied to the outside and inside of the worm gear body. When the driving motor is used as the gearless motor and the housing is formed as the worm gear body, And the output and efficiency of the warm drive unit can be increased while greatly reducing the volume.

According to the three-way elevator circulation system of the present invention, there is no need to arrange the rope in the elevator passage, and a plurality of rooms can be continuously operated at a constant interval like a train running on a rail, Therefore, the weight of the hoistway is greatly reduced, there is no restriction due to the rope, there is no restriction on the stroke, and the inconvenience of periodically replacing the rope can be eliminated.

In addition, since the worm driving portion and the room portion move independently along the arrangement of the worm supporting portions, it is also possible to move the compartment not necessarily in a vertical direction but in an inclined direction, or in a curved path instead of a straight line, In addition, horizontal movement can be realized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments. For reference, the same numbers in this description refer to substantially the same elements and can be described with reference to the contents described in the other drawings under these rules, and the contents which are judged to be obvious to the person skilled in the art or repeated can be omitted.

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

One or more of the three-way elevator circulation systems may be provided in a single building and may be used in combination with a conventional linear reciprocating elevator system that is not a circulating type.

The circulating elevator system can also be classified according to the high-speed or low-speed circulation. In the case of a high-speed circulating type or high-speed moving type elevator, the elevator system can be configured to pass a certain number of layers or a specific layer without passing through all the layers. In the case of the circulation type, since several ropless elevators can move together in one elevating space and users move only in one direction, the waiting time can be minimized so that the desired floor moving can be performed quickly.

The three-way elevator circulation system is operated in three elevating spaces, and switch spaces 40 are arranged at the upper and lower ends of the elevating spaces.

1 (a) shows a general reciprocating mode in which the ropiness elevator 1 travels up and down in the first to third lift spaces 10, 20 and 30, and FIG. 1 (b) 1 (c) shows a case in which the ropeless elevator travels upward in the elevation space in the center and downward in the elevation space in the left and right directions. For reference, the three ascending / descending spaces of the present embodiment are arranged in a row, but the three ascending / descending paths may be arranged in a triangular shape when viewed from above, or may be arranged in various shapes in consideration of space efficiency of the structure.

2, when the passenger increases, the ropless elevator moves upward only in both the first and third lift-up spaces except for the second lift-up space in the center, and the ropless lift moves only in the lower portion in the center lift- And the loopless elevator can be transferred to the different elevating spaces by the switch frames in the switch spaces provided at the upper and lower portions of the respective elevating and lowering spaces.

That is, in the first and second elevated spaces, the elevators circulate clockwise, and the elevators circulate counterclockwise in the second and third stand-by spaces. This is effective when the passenger is carried in two passageways of the first and third passageways among the three passageways, so that it is effective when the passageway is applied at the time of work.

Specifically, FIG. 2 (a) shows a typical reciprocating mode in which the ropless elevator reciprocates up and down in three passages, but there are not many passengers, so the ropless lifts 1, 3, 6 and 9 stand by in the switch space. When the number of passengers increases again, all the elevators are operated as shown in Figs. 2 (b) and 2 (c), in which the ropeless elevator is moved up and down by the switch frame in the switch spaces provided in the upper and lower portions of the respective lift spaces, As shown in FIG.

3 is a view for explaining a circulation mode suitable for a case where passengers moving downward from each floor of a building are increased. In this case, the passengers are loaded in two passages of the first and third lift- Therefore, it is effective when applied at lunch time.

Specifically, FIG. 3 (a) shows a typical reciprocating mode in which the ropless elevator reciprocates vertically in three passages, but there are not many passengers, so that the ropless elevators 1, 3, 6 and 9 stand by in the switch space. When the number of passengers increases, all the elevators are operated as shown in Figs. 3 (b) and 3 (c), and in the switch space provided in the upper and lower portions of the respective lift spaces, the rople- Elevators moving only downward in the first and third elevating spaces are continuously provided while elevators assembled in the first elevating and lowering elevating spaces are sequentially moved upwardly through the switch frame in the second elevating and lowering space The elevators of the first and second elevating spaces circulate counterclockwise to each other and the elevators of the second and third elevating spaces circulate clockwise to each other.

Here you can find the important value of the three-way elevator circulation system. The three-way elevator circulation system selectively uses three passageways according to the direction of transportation of the passengers. In the case of a built-in type elevator that circulates in one direction, the four-way elevator circulation system uses the three- Reduce to dogs.

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

Referring to FIG. 4, when one of the ropless elevators moving along the first to third elevated spaces fails, only the failed elevator is stopped, and the other elevators are partially reciprocated at the upper and lower portions of the failed elevator. Therefore, the two remaining elevating spaces other than the failed elevating space passage can still be reciprocally operated.

4 (a) shows a case where the elevator is stopped in the middle of the center passage, that is, the middle of the second elevating and lowering space, the other elevators positioned at the upper and lower portions of the still elevator can still be operated, It is still possible to circulate through left and right passages excepted.

Fig. 4 (b) shows a case where the elevator stops in the left passageway, that is, the first passageway, and the elevator can still be circulated in the center passageway and the right passageway.

4 (c) shows a case where the elevator stops in the right passage, that is, the third elevating and lowering space, and the elevator can still be circulated in the left and middle passages.

Referring to FIG. 5, a spare space is further provided beside the switch spaces of the first to third lift zones. Again, the switch frame, like the switch space, can carry the elevator while moving the switch frame, especially when the central passage elevator fails, to allow the switch frame to stay in the switch frame spare space for nonstop movement between the right and left passages . The number of spare spaces can be changed according to the intention of the designer in consideration of the passengers who use the building.

Spare space is a space where the switch frame can stay, and can be usefully used for efficient operation according to need such as dispatch control of an elevator room or an emergency situation.

FIG. 6 shows that the ropless elevators moving along the first to third lift spaces have a section that is set so as not to stop at all the floors, and has a straight section to smoothly communicate through the sections.

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 elevation spaces, eight elevators are circulated from the underground 7th floor (B7) to the 30th floor (30F), and the right side B The set runs from the B7 to the 30th floor (30F) on each floor without stopping, and the elevator can circulate through each passage on the 30th floor. And, 30 layers can be used to change to different sets.

The central control unit of FIG. 7 controls the ropless elevators moving along the first to third elevated spaces to be smoothly operated. The central control unit controls the positions, intervals, and speeds of the elevators and the switch frames, After checking the number of passengers in each floor and calculating the transportation capacity, speed, direction, etc. of the elevator, an optimal command for controlling the rople elevator and the switch frame is given to the ropley elevator Thereby improving operational efficiency.

8 shows that the lower portion of the switch frame provided at the upper ends of the first to third lift spaces is opened and the lower portion of the ropeless elevator is transferred to another lift space. For reference, the reference numerals for the explanation of Figs. 8 to 11 are shown in Fig. 8, and the other drawings are omitted.

The simulation in which the switch frame of Figs. 9 to 11 circulates at the upper part of the lift space is a simulation that assumes a case where a person who wants to move from the first floor to the upper floor arrives at the work time, Upward mode corresponds to the UP mode, and the upper two left and right switch frames 50 sequentially transport the ropless elevators to the central passage.

Specifically, referring to FIG. 9, 1> 2> 3> 4, the elevator is transferred to the switch space 40 provided in the uppermost right third lift-up space 30, And is moved to the second elevating and lowering space 20 at the center.

Referring to FIG. 10, the elevator conveyed together with the switch frame to the second elevated space in the center is conveyed downward through the second elevated space. In the leftmost first elevating and lowering space 10, another elevator is transferred and moved to the center second elevating and lowering space by the switch frame disposed in the switch space above the first elevating and lowering space.

11, the elevator conveyed together with the switch frame into the switch space above the second elevating space in the first elevating space moves downward through the central passage.

That is, in the left and right elevating and lowering spaces, the elevators move upward and move downward through the central elevating and lowering space.

12, the upper part of the switch frame provided at the lower ends of the first to third lift spaces is opened, and the ropless elevator that has entered the upper part is transferred to another lift space.

Figs. 13 and 14 show a simulation in which the switch frame is circulated in the lower part of the up / down space in the UP mode, and the passenger is lifted up in the two left and right passages, and the two lower left and right switch frames, And the ropless elevators are sequentially transferred to the elevating space passage.

19, in FIG. 19, a spare space 60 is further provided next to the switch space 40 in the first to third elevated 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, and it is necessary for the efficient operation according to the necessity of the dispatch control or the emergency situation by the circulation system.

According to the density of the operating elevator in the first to third elevating spaces, an atmospheric elevator waiting in the spare space is inputted into the first to third elevating spaces by the command of the central control unit, or the elevating operation is performed in the first to third elevating and lowering spaces It can be recovered to a spare space.

8, the first to third lifting spaces include a main guide 70 for transporting the ropless elevator, and the switch frame includes an extension (not shown) detachably connected to the main guide for transporting the loomless elevator, And a guide (80). Further, the ropeless elevator is conveyed together with the switch frame while maintaining a state of being engaged with the extension guide.

15 and 16 are structural diagrams of a worm magnetic levitation elevator which is a ropless elevator. 15 and 16, the ropeless elevator includes a room part 2 moving along the first to third lifting spaces and a worm driving part 90 moving together with the room part and having a rotation axis parallel to the moving path of the room part, And the main guide and the extension guide may be arranged so that the interval between the teeth 92 of the worm gear body 90 of the worm drive unit 90 is changed by a period And a worm support portion 70 including a plurality of support teeth 72 formed to correspond to the teeth of the worm drive portion. The worm drive portion and the worm support portion maintain low resistance contact. Further, the worm driving portion and the worm supporting portion can maintain low resistance contact by using rolling contact or magnetic levitation. The guide rail holder 4 fixed to the passenger compartment 2 is coupled to the guide rail 52 so that the passenger compartment can be guided by the guide rail.

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

The worm driving unit includes a worm gear body for providing a tooth surface of the worm gear and a driving unit for rotating the worm gear body inside the worm gear body. The driving unit includes a rotating shaft 97, and a rotor 99 mounted on the inner surface of the worm gear body corresponding to the stator. The worm gear body can rotate around the rotation axis by the interaction of the stator and the rotor.

The ropless elevator includes a cabin, a lift frame, a worm drive, and a worm support, and the cabin of the ropley elevator can move along the lift space in the building by the interaction between the worm drive and the worm support. The ropiness elevator may further include an independent control unit, an air conditioner, a wireless communication module, and the like, so that the ropiness elevator can be smoothly driven and controlled. The worm driving unit includes a worm gear body having a worm gear shape, and teeth are formed on an outer surface of the worm gear body. The worm gear body includes a rotary shaft arranged in parallel with the traveling direction in the ropless elevator, and is rotatably mounted around the rotary shaft. In the present embodiment, permanent magnets or electromagnets 91 and 93 of the same polarity may be provided on the teeth of the worm gear body and the worm support teeth.

The worm drive unit rotates the worm gear body in the lifting device, and the tooth surface of the worm gear body can receive a force that can be lifted without being in close contact with each other due to the repulsive force with the worm support part. And can be raised or lowered slidably together with the room part in a state of being levitated on the worm support part in accordance with the rotation of the worm gear body.

Since the room part can be lifted and lowered by using the worm drive part, the conventional rope or wire is not used, and it is not necessary to install a traction machine or a machine room on the uppermost layer. That is, the worm driving unit installed at the upper portion or the lower portion is used in each of the rooms, and the rotation of the worm driving unit can be switched to the up and down movement of the ward unit independently of the rope.

By omitting the rope, it is possible to eliminate the burden on the weight of the huge rope when applied to a skyscraper. In addition, the structural rope can be smoothly moved and the burden on the balance weight can be eliminated.

Since the rotor rotates by magnetic levitation instead of friction, the rotation can be converted to the position energy without energy loss. On the other hand, when the rotor is lowered, the desired speed and control can be achieved with only a minimum amount of energy. 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.

The support value of the worm support portion can be shifted by one pitch corresponding to one rotation of the worm gear body. Therefore, when it is assumed that the pitch of the worm supporting part is about 25 to 50 cm, the worm driving part can sufficiently provide a speed of about 500 to 1000 m / min by only rotating at about 2000 rpm. That is, an ultra-high-speed elevator can be easily implemented.

It is possible to easily implement a twin system in which two or more rooms can be moved in one lifting space. Since no rope is used, two or more rooms can be freely arranged in the same space. It is possible to easily control the ropless elevator by using the wireless communication module mounted in the mutual room part. Especially, since there is no obstacle in the elevating space, the wireless communication module can be used more easily.

The ropless elevator according to the present embodiment can prevent accidents in which the passenger compartment falls helplessly even when the worst 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 can stably move within the elevating and lowering space by the elevating frame, and the guide rail holder of the elevating frame safely surrounds the guide rails. The rollers of the guide rail holders maintain a low-resistance friction state with the guide rails so that they can be guided to move without shaking in the lift space. Of course, in addition to the roller, the magnetic guide using magnetic force can control the shaking with the lifting frame.

The worm gear body may be provided in a hollow shape, and both ends of the worm gear body may be rotatably mounted on the rotary shaft using a bearing (95). 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, and the like.

The tooth surface of the worm gear body is supported by rollers exposed on the upper surface of the support structure, and can be raised or lowered with the room part by sliding on the roller of the worm support part according to the rotation of the worm gear body.

The worm support includes magnets or electromagnets disposed at regular intervals, and the rollers may be provided at or near the contact surface of the worm support. The roller can prevent direct contact with the tooth surfaces of the worm supporting part and the worm gear body, and can prevent the magnet structure from being damaged at mutual contact surfaces even if 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 with a hollow shape. A coil stator and a coil rotor are provided as a combination of coil-coils from the top to the inside of the worm gear body, and a coil stator and a magnet rotor can be provided as a combination of coil-magnets below. Of course, the coil rotor can also be provided in the form of an iron core rather than a coil.

The rotational torque and the rotational speed can be appropriately adjusted by using two or more pairs of stator and rotor, and generation of inductive power according to the rotation of the worm gear body can also be expected. 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.

When the switch frame is moved, the support teeth of the extension guide can be moved together with the support frame 82 of the extension guide 80 by being engaged with the switch frame 50. This can reduce the risk of the loose- It is an important part in terms of blocking.

In addition, the structure in which the switch frame is hooked to the horizontal support member 110 coupled with the outer wall of the lifting and lowering space so that the switch frame is safe for gravity, enhances safety.

In the structure in which the switch frame is hung on the horizontal support, two horizontal support rods are provided and the wheel (including the rollers) can be rolled on the horizontal support rods, and the switch frame is hooked on the wheel axle.

It is possible to drive the wheel by driving it on the wheel shaft through a lever, a wire, a belt, a chain or the like using a motor or a hydraulic pressure as a driving force for driving the wheel, and may move to the magnetic levitation system instead of the wheel.

FIG. 20 illustrates that a switch frame can be applied to a two-way elevator circulation system in a three-way elevator circulation system, wherein the elevator can be circulated by a switch frame at two elevation spaces.

In addition, as shown in FIG. 21, driving the wheel axle with the robot arm 120 plays a role of securing the safety of the switch frame and controlling it quickly and smoothly.
