Description

TECHNICAL FIELD [0001] The present invention relates to an elevator using a worm driving unit,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevating apparatus using a worm driving unit, and more particularly, to an elevating apparatus including an elevator or other lifting apparatus capable of transporting passengers or cargo 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.

The present invention provides a lift device that provides a ropeless lift device using a worm drive, and can improve stability and reliability.

Particularly, the present invention provides a lift device capable of preventing a shake when using a cabin and providing a comfortable ride feeling.

Further, the present invention provides a lift device capable of minimizing power consumption.

According to a preferred embodiment of the present invention, the lift device moves together with the cabin and the cabin moving along the elevator elevator passage, and the worm drive device moves the rotary shaft along the moving path of the cabin. A worm supporter provided in the elevating passage along the moving path of the passenger compartment and including a plurality of supporting teeth formed so as to correspond to the worms of the worm driving portion at regular intervals of the worm driving portion, and a worm supporting portion provided on the guide rails provided in the elevating passage And a magnetic levitation support portion for supporting the movement of the cabin portion.

The worm driving unit includes a body in the form of a worm gear, and the body of the worm driving unit is capable of providing a force for lifting and lowering while being meshed with the supporting teeth of worm supporting parts arranged at regular intervals. 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.

The worm support is configured to reduce friction between the support and the worm by using a magnetic levitation force. The worm support portion may be provided in various structures capable of providing a magnetic levitation force, and the present invention is not limited or limited by the structure of the worm support portion. For example, each support may be provided with a first magnet module that provides a repulsive force or attraction force upon power application, and a second magnet module may be provided along the worm axis to provide mutual magnetic levitation forces with the first magnet module have.

The magnetic levitation support may be provided in various structures capable of supporting the room by using the magnetic levitation force, and the structure of the levitated support may be variously changed according to the required conditions and design specifications.

The magnetic levitation support portion may include a guide rail mounted to the elevation passage and an electromagnet unit connected to the cabin portion and provided to form a mutual magnetic levitation force with the guide rail, The guide rails and the electromagnet units can be supported apart from each other by the magnetic levitation force.

For example, the electromagnet unit may include a first magnetic pole, a second magnetic pole having the same polarity as the first magnetic pole and disposed to face the first magnetic pole, and a second magnetic pole having the same polarity as the first magnetic pole and the second magnetic pole, And an end portion of the guide rail is disposed between the first magnetic pole and the second magnetic pole to face the third magnetic pole of the electromagnet unit So that mutual magnetic levitation force can be formed with the first to third magnetic poles. In addition, the first to third magnetic poles formed on the electromagnet unit and the ends of the corresponding guide rails may be configured to have the same polarity, but in some cases, the first to third magnetic poles of the electromagnet unit and the corresponding guide rails May have different polarities from each other.

In another example, the electromagnet unit may include a first magnetic pole, and a second magnetic pole having the same polarity as the first magnetic pole and disposed to face the first magnetic pole, and may be formed in a substantially " May be disposed between the first magnetic pole and the second magnetic pole to form mutual magnetic levitation force with the first magnetic pole and the second magnetic pole.

A plurality of standardized guide rails can be continuously arranged along the vertical direction, and the electromagnet units can be continuously supported by the continuously arranged guide rails. Further, the support teeth can be mounted on the guide rails to be mounted on the lift rails via the guide rails. It is also possible to selectively supply power to the plurality of guide rails disposed along the vertical direction corresponding to the movement of the electromagnet unit.

In addition, the lift device may include a brake portion for selectively stopping the movement of the electromagnet unit relative to the guide rail. The brake portion can be provided in various structures that can stop the movement of the electromagnet unit relative to the guide rails. In one example, the brake portion may include a brake pad that is provided in the electromagnet unit so as to be contactable with and spaced from the guide rail, and the brake pad may be pressed to the guide rail in a state in which the power is off. Further, the brake portion may include an elastic pressing portion for bringing the brake pad into close contact with the guide rail, and a separating portion that operates in reverse to the elastic pressing portion upon power application.

Further, at least one of the guide rail and the electromagnet unit may be provided with a guide roller for limiting the approach distance between the guide rail and the electromagnet unit. When the power supply to the guide rail and the electromagnet unit is interrupted, The unit may be supported spaced apart by a guide roller to maintain a suitable minimum distance.

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.

Further, according to the present invention, since the passenger compartment can be supported by the magnetic levitation force by the magnetic levitated support portion, vibration and shaking can be prevented when using the passenger compartment, and a more comfortable feeling of boarding can be provided.

In addition, since the plurality of guide rails continuously arranged along the vertical direction can selectively operate corresponding to the movement of the electromagnet unit, unnecessary power consumption can be prevented, and power consumption can be minimized.

In addition, according to the present invention, the movement of the electromagnet unit relative to the guide rail can be stopped by the braking portion in a state where power supply to the magnetic levitation support portion is cut off, thereby improving the stability and reliability.

1 and 2, the elevating apparatus 100 includes a room 110, a lifting frame 120, a worm driving unit 130, and a worm supporting unit 170, The worm driving unit 110 can move along the elevator elevation passage in the building by the interaction between the worm driving unit 130 and the worm supporting unit 170. [ The elevating device 100 may further include an independent control unit 180, an air conditioner 185, and a wireless communication module 190, so that the elevating device 100 can be smoothly driven and controlled.

The worm driving unit 130 includes a worm gear body 140 having a worm gear shape and worm teeth 142 are formed on an outer surface of the worm gear body 140. The worm gear body 140 includes a rotating shaft arranged in parallel with the moving direction of the lifting device 100, and is rotatably mounted around the rotating shaft.

The worm supporting portion 170 is provided in the elevating passage corresponding to the worm 142 of the worm gear body 140. In this embodiment, the worm supporting portion 170 is formed in a rack shape corresponding to the worm gear body 140 And can function as a rack supporting part.

Since the room 110 can be lifted and lowered using the worm driving part 130, it is not necessary to use a conventional rope or wire, and there is no need to install a hoisting machine or a machine room on the uppermost layer. That is, the worm driving unit 130 installed at the upper portion or the lower portion of each room 110 can be used and the rotation of the worm driving unit 130 can be switched to the up-down movement of the room unit 110 without depending on the rope .

Therefore, the driving system of the lifting apparatus 100 is simplified, and the burden on the weight of the huge rope can be eliminated when the rope is applied to the skyscraper by omitting the rope. 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.

The worm supporting member 170 can be moved by a pitch corresponding to the support value of the worm supporting unit 170 in response to one rotation of the worm gear body 140. Therefore, when it is assumed that the pitch of the worm supporting part 170 is about 25 to 50 cm, the worm driving part 130 can sufficiently provide a speed of about 500 to 1000 m / min by rotating only about 2000 rpm. That is, as shown on the left side, the super-high-speed elevator can be easily implemented.

It is possible to easily realize a twin system in which two or more rooms 110 can move in one elevating passage. The rope is not used, so that two or more rooms 110 can be freely placed in the same space and the control of the elevating apparatus 100 can be performed using the wireless communication module 190 mounted on the mutual room 110 Can be easily performed. Particularly, since there is no obstacle in the elevating passage, the use of the wireless communication module 190 may be easier.

The elevating apparatus 100 according to the present embodiment can prevent an accident that the occupant 110 falls helplessly even when the worst situation occurs in which the power is cut off or the braking apparatus 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 rotational torque and the rotational speed can be appropriately adjusted by using two or more pairs of stators and rotors, and generation of induced electric power due to the rotation of the worm gear body 140 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.

In addition, the cogging phenomenon can be controlled by adjusting the gap between the magnet and the coil. In this case, when the power is cut off, the cogging phenomenon may be used to decelerate the rotation of the worm gear body 140.

An auxiliary roller (not shown) may be provided around the support teeth 172. The auxiliary rollers can maintain a suitable minimum distance between the facing electromagnet modules and prevent damage due to physical friction between the worm wheel and the supporting teeth when the worm driving part rotates together with the repulsive force .

For this purpose, a die casting method or the like can be used.

The first magnet module 210 may be electrically connected by a wiring unit (not shown), and the second magnet module 220 may be electrically connected by a wiring unit (not shown) The first magnet module 210 and the second magnet module 220 may generate a magnetic field in each of the first and second magnet modules 210 and 220 but do not interact with each other The magnetic field is unnecessarily generated, which may result in unnecessarily consuming power.

To this end, a magnetic field is selectively formed only at a portion of the tooth surface of the worm gear body 140 that is substantially supported by the worm support portion 170 (or a second magnet module capable of exerting a repulsive force or attraction with the first magnet module) .
