The present specification relates to a transfer device using a magnetic brake using a magnetic induction phenomenon generated between a permanent magnet and a conductor. When a plurality of permanent magnets are arranged and moved at regular intervals from the conductor, a cosine-shaped magnetic field is formed between the permanent magnets as shown in FIG. 6, so that an induced current is generated in the conductor, which causes the movement of the permanent magnet. Generate traction in the direction of obstruction. Therefore, the transfer device free fall in the direction of gravity is guided by the magnetic brake to smoothly descend at a constant speed to help passengers move quickly and safely. The traction force generated in the transfer device depends on the strength of the permanent magnet, the type of conductor and the distance between the permanent magnet and the conductor, the number and arrangement of the permanent magnet, the type, spacing and arrangement of the conductor, and the permanent magnet and the conductor. By varying the distance between, the lowering motion of the conveying device can be varied.

As shown in FIG. 13, the speed and acceleration of the conveying device converge differently depending on the weight of the conveying device. As shown in FIG. 5, in order to adjust the lowering condition of the conveying device according to the number of occupants. The adjustment lever 110 is used to adjust the distance between the conveying device and the conductor. At this time, as the lowering speed of the transfer device exceeds the limit speed, as shown in FIG. 14, since the traction force is rapidly reduced, it is difficult to expect a smooth lowering effect, so the device needs to be designed to satisfy the appropriate driving conditions. There is.

The conveying device arranges a plurality of permanent magnets on the body so that the north pole and the south pole intersect, and attaches and drives conductors such as copper or aluminum to the wall of the building and vice versa. There is a method of arranging a plurality of permanent magnets on the wall of the building so that the N pole and the S pole cross each other, and the principle of operation of the two methods is the same. The latter method is as shown in Fig. 15, and the description will be given focusing on the former method.

In the state in which a plurality of permanent magnets are arranged in the body of the transfer device so that the N pole and the S pole cross, the falling conditions of the transfer device can be changed by changing the type, thickness and arrangement of the conductor rails to adjust the traction force. For example, the middle part of the conductor rail can be used to increase the speed of descending the conveying device using aluminum conductors, and the copper conductors, which are relatively more conductive than aluminum, can be used to increase the traction force, resulting in a large deceleration effect. have. In addition, the conductors may be discontinuously arranged or the thickness of the conductors may be changed for each section to change the falling conditions. During the descent drive, the occupant may use the adjustment lever to adjust the gap between the permanent magnet and the conductor rail, thereby actively changing the traction force to change the descent motion.

Escape devices used in the event of a disaster such as a fire to date, as shown in Figures 1a, 1b, 1c using the tack of the fluid viscosity or friction mechanism to reduce the descending speed of the rope and elevator for escape, or Figure 2 As shown in the figure, there are emergency electric elevators that evacuate lives on the roof using capacitors or other electric power as main power. However, when the unloading machine is used by an unskilled person, it can feel the fear of falling, and the existing non-powered elevator decelerates using friction force, which may cause the rope to break or the friction mechanism to be broken. May lower the reliability. And only one person can use it at a time, and if you escape from the high-rise there is a risk of falling by mistake of the escape. The emergency electric elevator requires a separate main electric power, even if a storage battery is used, its capacity is limited, and since the main power is electric power, it is limited in the number of operations and may not be supplied with electricity in case of fire. In addition, due to the complicated structure of the electric device and the mechanical mechanism, there is a risk of failure in an emergency.

The transfer device using the magnetic brake proposed in the present invention does not use electric power as the main power, has the advantages of easy operation, trouble-free operation, and physically safe and psychological stability for the passengers by inducing a smooth downward movement.

To provide a transfer device that does not.

Another object of the present invention is to provide a structure in which the braking force is obtained in a non-contact manner, thereby increasing the reliability of mechanical failure or damage.

Still another object of the present invention is to provide a structure that prevents a sudden drop by inducing a smooth downward movement by using the traction force generated between the permanent magnet and the conductor.

Another object of the present invention is to place a counterweight or another conveying device having a weight similar to that of the conveying device on the opposite side by using a pulley so that the lowered conveying device smoothly rises back to the roof of the building. It is to provide a structure that enables the operation.

Another object of the present invention is to take advantage of the phenomenon that when the distance between the conductor and the permanent magnet is large, the traction is reduced, and when one side of the rope is the transfer device and the other is the counterweight, the distance between the permanent magnet and the conductor is reduced. It is to provide a structure that allows for a smooth up or down movement by adjusting.

Still another object of the present invention, by attaching a plurality of iron core solenoid to the transfer device, can be momentarily driven when stopped in an unexpected situation in the middle of driving to escape the fixed state, when the running speed is too fast from the outside or inside It is to provide a structure that can adjust the speed of the conveying device.

Still another object of the present invention is to provide a structure in which a conveying device smoothly lands on the ground by providing a shock absorber or a spring-hydraulic shock absorber using a permanent magnet on the ground.

In order to achieve the above object, the conveying apparatus of the present invention has a constant distance between the elevator and the permanent magnet of the elevator and the elevator having a plurality of permanent magnets arranged at regular intervals while crossing the N pole and the S pole. On the contrary, the elevator having the conductor attached to the wall, or vice versa, has a constant distance from the elevator and the conductor of the elevator, and a plurality of permanent magnets intersect the N pole and the S pole on the wall of the building to have a constant distance. At the same time, it is provided with a lever that can adjust the distance between the conductor and the permanent magnet or to be fixed to the ground when reaching the ground, and at the same time having a guide for smoothly descending the elevator, A plurality of iron core solenoids for driving the elevator internally are attached to the elevator and at the same time, Including that by mounting the transfer device has a structure to have a smooth braking to reach the ground is characterized in that is made.

The lock arm 105 may be mounted to the lock arm clamp 109 and move like a slide, and the lock arm 105 is attached to the lock arm 105 to smoothly move along the guide slide 500. The adjustment lever 110 is attached to the lock arm 105 to allow the occupant to adjust, and is connected between the adjustment lever 110 and the transfer device body 101 by the lock spring 107. The upper portion of the transfer device body 101 is equipped with a towing rope 600 to connect with the counterweight 400 or other transfer device via the pulley 300. As shown in Figs. 3, 4, and 9, the wall of the building is attached with an iron plate 203 facing the permanent magnet and an iron plate 204 facing the iron core solenoid, and a conductor rail facing the permanent magnet on the iron plate. Attached to the conductor rail 202 facing the core 201 and the iron core solenoid, the permanent magnet 102 and the iron core solenoid is configured to have a constant distance between the conductor rail (201, 202). As illustrated in FIGS. 3 and 4, a shock absorber 700 is installed on the ground for safe landing of the transfer device 100. The spring-hydraulic shock absorber of the ground shock absorber 700 has a structure as shown in FIG. 12A, and the hydraulic damper 702 and the shock absorbing spring 703 are attached to the bottom of the collision plate 701 to prevent the spring-hydraulic shock absorber.

A plurality of poles such as a permanent magnet 706 attached to the bottom of the collision plate 705 to face each other is attached to the case 707 to serve as a spring and at the same time act as an attenuator. The permanent magnet impingement plate 705 and the permanent magnet buffer embedding case 707 are made of steel to shield the magnetic force of the permanent magnet 706 in the shock absorber.

Then, the operation of the transfer device using the magnetic brake according to an embodiment of the present invention having the above configuration will be described in more detail with reference to FIGS. 3 to 4 and 5.

When a disaster such as a fire occurs, passengers evacuated to the roof board the passenger device 100 of the transfer device and pull the lever 110 of the locking device as shown in FIGS. As shown in FIGS. 4 and 5, the roller 106 of the locking device 110 is lowered along the guide slide 500. At this time, the vehicle 100 is decelerated by a force proportional to the speed by the magnetic field formed by the induced current generated in the conductor rail 201 by the permanent magnet 102 to maintain an appropriate speed. In this case, as shown in FIG. 6, the braking force is maximized by making the change of the magnetic field form a cosine wave according to the alternating arrangement of the permanent magnets 102, and as shown in FIG. 7, the permanent magnets 102 are conductor rails. 201 is made of a magnetic closing circuit by the iron plate 203 on the back and the body 101 of the vehicle 100 to minimize the leakage magnetic force. As shown in FIG. 11B, the roller 106 is automatically fixed by the spring 107 along the guide slide 500 as shown in FIG. 11B. As shown in FIG. 4, when the other side of the transfer apparatus 100 is another transfer apparatus 100, when one transfer apparatus 100 descends, the other side is pulled by the pulley 300 and the rope 600. Since the transfer device 100 of the ascend automatically, the next person can escape the roof in the same process. The difference between the locking device in the case where the opposite side of the conveying device 100 is the counterweight 400 and in the case of another conveying device 100 is that in the former case, as shown in FIG. In the rooftop and the ground part, and in the latter case, as shown in Fig. 4, the fixing grooves on the wall are only on the rooftop. If space limitations or other conditions are not available, one of the transfer devices 100 may be replaced by the counterweight 400, and in this case, all the operating principles are the same. However, when one side is the counterweight 400, since the one with the faster moving speed is advantageous when returning to the roof, the adjustment lever 110 is used to increase the distance between the permanent magnet 102 and the conductor rail 201. Enable rapid uplift movement of the device 100.

As shown in Figs. 12A and 12B, a shock absorber 700 is installed on the ground to achieve a smooth stop when the transfer device 100 reaches the ground. The shock absorber 700 may use a spring-hydraulic shock absorber as shown in FIG. 12A and a shock absorber using a repulsive force of a magnet as shown in FIG. 12B, depending on the type. A shock absorber using a spring-hydraulic shock absorber utilizes a hydraulic damper 702 and a shock absorbing spring 703 to induce a smooth stop of the conveying device. The shock absorber using the repulsive force of the magnet attaches a plurality of permanent magnets 706 in the permanent magnet buffer embedding case 707 such that the same poles face each other, thereby generating a shock absorbing effect by using the repulsive force.

As described in detail above, the transfer device using the magnetic brake proposed in the present invention overcomes the limitations of the conventional emergency escape device, which is completely dependent on mechanical friction or electric power, when applied as an emergency escape device, and thus has a large number of conductors. It is a system to transport passengers safely by generating traction from the magnetic induction phenomenon between permanent magnets and to carry passengers safely. It does not use electric power as the main power because it moves down and up using gravity. In addition, it is easy to operate, and the structure is simplified to minimize mechanical defects, so it is possible to exhibit an effective performance as a transportation and emergency escape device such as hardly any troubles or safety accidents during operation.
