Description
Technical Field
The present invention relates to a safe leveling height adjusting system for an elevator, and more particularly, to a safe leveling height adjusting system for an elevator for adjusting the height of a car that ascends and descends along a hoistway without a level difference from a landing-side floor prepared for each floor when the elevator is operated.
Background
In general, an elevator is a device in which a car carrying passengers or freight is raised and lowered along a hoistway, and the passengers or freight are transported to landings on respective floors of a building.
In such an elevator car, when the car is lifted and lowered along a hoistway and stopped to unload passengers to a landing on each floor of a building or to load passengers from the landing to the car, the height of the car, that is, the leveling height of the car is adjusted so that the floor surface of the car and the floor surface on the landing side are kept horizontal, and when the floor surface of the car and the floor surface on the landing side are not adjusted in height so that the floor surface of the car and the floor surface on the landing side do not reach the horizontal level and a step difference occurs, there is a problem that a safety accident such as a passenger being tripped by the step difference occurs when the passenger goes out from the car in the direction of the landing or goes into the car from the landing.
Therefore, in order to operate the elevator, a floor leveling height of the car is adjusted by providing a floor leveling height adjusting device so that the floor of the car that stops at a landing prepared on each floor of the building while ascending and descending along the hoistway is kept horizontal with the floor on the landing side.
As described above, in the device for adjusting the leveling height of the car, in order to maintain the level of the floor of the car, which is stopped with reference to the landings prepared on each floor while ascending and descending along the elevator shaft, and the floor on the landing side, generally, a level adjustment switch is provided at the upper end of the outside of the car, and a switch operating part is provided at a position corresponding to each floor of the building of a guide rail provided in the vertical longitudinal direction along the elevator shaft, so that when the car stops at the landing of the target floor while ascending and descending along the elevator shaft, if the level adjustment switch provided at the upper end of the outside of the car is driven by the operating part, a signal for ending the height adjustment of the car is transmitted to the control part, and the car is stopped, thereby adjusting the leveling height of the car to stop the car.
In the conventional general flat bed height adjusting apparatus for an elevator as described above, in order to adjust the flat bed height of the car by setting each floor of the building at a setting position of the switch operating part of the guide rail, and to perform the flat bed height operation of the car by the conventional flat bed height adjusting apparatus for an elevator as described above, one operator needs to operate the up-down switch for low speed operation provided at the upper part of the car to raise or lower the car at a low speed, and the other operator observes the alignment between the floor of the car and the floor on the landing side inside the car, and when it is determined that the flat bed height of the car is adjusted, the operator on the car is notified to turn off the on-up down-down switch for low speed operation, and to enable the height adjusting switch to be driven at the height-adjusted position, an operator on the lift car adjusts the setting position of the switch control part and sets the switch control part on the guide rail according to each layer.
In the conventional floor leveling height adjusting device for an elevator, since two operators find out the positions where the floor of the car and the floor of the landing side are kept horizontal one by one while moving each floor and install the switch operating part, the floor leveling height adjusting operation of the car requires a large amount of operators and operation time.
In order to solve the above-described problems, recently, the floor leveling height of the car is adjusted by providing a switch operating section at a floor, calculating the position from the floor of the landing to the position where the switch operating section is provided, and providing the switch operating section on the guide rail at a position spaced apart from the floor of the landing on each floor.
However, in the case where the switch operating section is installed as described above, since the operator needs to manually calculate the distance from the floor of the landing to the position where the switch operating section is installed on the floor whose leveling height has been adjusted, and apply the calculated distance to all floors of the building, an error occurs not only in measuring the distance from the floor of the landing to the switch operating section, but also in measuring the distance from the floor of the landing to the position where the switch operating section is to be installed in order to install the switch operating section.
In addition, a load may be applied to the switch operating part due to the operator stepping on the switch operating part during the maintenance operation of the elevator, which may cause the position of the switch operating part to be changed, and thus the problem of the uneven floor height of the car after the maintenance operation of the elevator frequently occurs.
In addition, in the conventional floor leveling height adjusting device for an elevator, since the switch operating part is fixed to the guide rail by a bolt, a nut, or the like, the switch operating part is deviated in installation angle or sags due to its own weight, and the floor leveling height of the car cannot be accurately adjusted, and the floor of the car on each floor and the floor on the landing side cannot be kept horizontal, so that there is a problem that a safety accident such as tripping of a passenger may occur due to a step difference between the floor of the car and the floor on the landing side when the passenger gets in and out.
In addition, in the case of an elevator, when a power failure occurs, the elevator frequently stops between floors, and in the case of an elevator provided with a conventional general flat floor height adjusting device for an elevator, when a power failure occurs, the flat floor height adjusting device stops operating, and even if a manager uses a backup power supply to lift the car to a near landing, the car door cannot be opened because the manager cannot accurately align the flat floor height of the car, and therefore, in the case of a general manager who does not have special elevator knowledge, the passenger cannot be rescued, and the passenger can be rescued only by requesting a professional rescuer such as 119 rescuer to move, and opening the car door by forcibly opening the landing door or the rescuer climbs to the upper part of the car to open an emergency exit at the upper part of the car.
More specifically, in an elevator, when the landing and the car are not aligned in the floor leveling height, since the landing door and the car door cannot be opened, even if the car is raised and lowered by the backup power supply, it is difficult to accurately align the floor leveling heights of the landing and the car, and thus it is difficult to open the car door.
Therefore, in the case of a general manager, when a power failure occurs, if the flat bed heights of the cars are not aligned, passengers cannot be saved at all, even if a professional rescue team member goes out, the landing doors need to be opened, the car doors need to be opened forcibly, or the rescue team member climbs to the upper part of the cars and opens the emergency exit on the upper part of the cars, so that the passengers can be saved.

Referring to fig. 1 to 3, a safety leveling height adjusting system 100 for an elevator according to an embodiment of the present invention may include a sensor driving module 110, a leveling height sensor module 120, and a control part 130.
The sensor driving module 110 may be provided to each of the prepared lower frames 210 of the floors of the building.
For example, the sensor driving module 110 may include a fixing frame 111 and a permanent magnet driving part 112.
The fixing frame 111 may fix the lower surface of each of the story station lower frames 210 prepared on each story of the building based on a plurality of fixing members 114.
For example, the fixing frame may include a fixing portion 111a and a body portion 111 b.
The fixing portion 111a may be fixed to a lower surface of each of the story station lower frames 210 prepared on each story of the building based on a plurality of fixing members 114.
Among them, the fixing member 114 may use a bolt and a nut.
The body part 111b may extend from the fixing part 111a and be bent toward a lower direction of the fixing part 111a to form an l-shaped.
When the car 300 stops at each landing 200, the permanent magnet driving part 112 faces the leveling height sensor module 120 with a predetermined interval, and is formed to extend toward the fixed frame 111, i.e., the upper and lower longitudinal directions of the body part 111b by a predetermined length and attached to the body part 111b to drive the leveling height sensor module 120 based on a magnetic force.
Further, the sensor driving module 110 may further include an angle fixing part 113.
The installation angle fixing portion 113 extends from the upper end of the fixing frame 111, i.e., a fixing portion 111a, and is bent to be supported by the side surface portion of the landing lower frame 210.
When the fixed frame 111 is fixed to the landing lower frame 210 by the fixing member 114, the installation angle fixing portion 113 is supported by the side surface portion of the landing lower frame 210, so that the angle of the fixed frame 111 is not deviated when the fixing portion 111a of the fixed frame 111 is fixed to the landing lower frame 210 by the fixing member 114 such as a bolt and a nut, and therefore, the fixed frame 111 can be installed to the landing lower frame 210 so that the permanent magnet driving portion 112 and the floor level sensor module 120 always face each other.
More specifically, if the fixing portion 111a of the fixing frame 111 is fixed to the lower surface of the landing lower frame 210 using the fixing member 114 such as the bolt and the nut without the installation angle fixing portion 113 for supporting the side surface portion of the landing lower frame 210, the fixing portion 111a of the fixing frame 111 is fixed to the lower surface of the landing lower frame 210 by rotating the fixing member 114 such as the bolt and the nut, and is interlocked with the fixing portion 111a of the fixing frame 111 or the fixing member 114 together with the fixing member 114, and is rotated and fixed in the rotating direction of the fixing member 114, and therefore the body portion 111b to which the permanent magnet driving portion 112 is attached and the floor height sensor module 120 cannot be installed facing each other in the front direction, and an operation error of the floor height sensor module 120 can be induced, and therefore, it is necessary to adjust the installation angle of the fixing frame 111 after the fixing frame 111 is installed, resulting in an increase in the installation time of the sensor driving module 110.
Therefore, according to the safety leveling height adjusting system 100 for an elevator according to an embodiment of the present invention, the installation angle fixing portion 113 is extended and bent at the upper end portion of the fixing portion 111a to be supported by the side surface portion of the landing lower frame 210, and even in the process of screwing the fixing member 114 such as the bolt and the nut and fixing the fixing portion 111a to the lower surface of the landing lower frame 210, since the installation angle fixing portion 113 is supported by the side surface portion of the landing lower frame 210, it is possible to prevent the fixing portion 111a from being rotated by the rotational force of the fixing member 114 such as the bolt and the nut which fixes the fixing portion 111a to the lower surface of the landing lower frame 210.
Therefore, according to the sensor driving module 110 of the safety leveling height adjusting system 100 for an elevator according to an embodiment of the present invention, as long as the fixing frame 111 is provided on the lower surface of the landing lower frame 210 by the fixing member 114, even if the installation angle of the fixing frame 111 is not corrected, the sensor driving module 110 is installed such that the permanent magnet driving part 112 and the leveling height sensor module 120 always face each other, and thus the sensor driving module 110 can be installed quickly and easily.
The floor leveling sensor module 120 is provided in the car lower frame 310, and if the car 300 ascends and descends along the hoistway 400 to reach each landing 200 prepared on each landing and faces the sensor driving module 110 provided in the landing lower frame 210 in a state of being spaced apart at a predetermined interval, the first floor leveling completion signal and the second floor leveling completion signal can be sequentially generated based on the magnetic driving of the permanent magnet driving part 112 of the sensor driving module 110.
For example, the flat bed height sensor module 120 may include a fixed frame 121 and first and second electromagnet switch sensors 12 and 123.
If the car 300 ascends and descends along the hoistway 400 and arrives at each landing 200 prepared on each landing, the fixing frame 121 may be fixedly provided to a lower surface of the car lower frame 310 by a plurality of fixing members 124 so as to face in a state of being spaced apart from the sensor driving module 110 by a predetermined interval.
For example, the fixing frame 121 may include a fixing portion 121a and a body portion 121 b.
The fixing portion 121a may be fixed to a lower surface of the car lower frame 310 based on a plurality of fixing members 124.
Among them, the fixing member 124 may use a bolt and a nut.
The body part 121b may extend from the fixing part 121a and be bent toward a lower direction of the fixing part 121a to form an l-shaped.
The first and second electromagnet switch sensors 122 and 123 are respectively disposed at upper and lower portions of the fixed frame 121, and if the car 300 ascends and descends along the hoistway 400 to reach each landing 200 prepared at each landing and faces the sensor driving module 110 disposed at the lower frame 210 of each landing in a state of being spaced apart at a predetermined interval, the first and second electromagnet switch sensors 122 and 123 may be sequentially driven from any one of them based on the sensor driving module 110 and sequentially transmit a first height adjustment end signal and a second height adjustment end signal to the control portion 130.
Further, the flat bed height sensor module 120 is similar to the sensor driving module 110, and may further include an angle fixing part 123.
The installation angle fixing part 123 may extend from an upper end of the fixing frame 121 and may be bent to be supported by a side surface of the car lower frame.
When the fixed frame 121 is fixed to the car lower frame 310 by the fixing member 124, the installation angle fixing portion 123 is supported by the side surface portion of the car lower frame 310 as described above, so that the angle of the fixed frame 121 is not deviated when the fixing portion 121a of the fixed frame 121 is fixed to the car lower frame 310 by the fixing member 124 such as a bolt and a nut, and therefore, the fixed frame 121 can be installed to the car lower frame 310 such that the first and second electromagnet switch sensors 122 and 123 always face the sensor driving module 110.
More specifically, if the fixing portion 112a of the fixing frame 121 is fixed to the lower surface of the car lower frame 310 using the fixing member 124 such as the bolt and the nut without the angle fixing portion 123 provided to be supported by the side surface portion of the car lower frame 310, the fixing member 124 such as the bolt and the nut is rotated to fix the fixing portion 121a of the fixing frame 121 to the lower surface of the car lower frame 310, and is interlocked with the fixing portion 121a of the fixing frame 121 or the fixing member 124 together with the fixing member 124, and is rotated and fixed in the rotating direction of the fixing member 124, so that the body portion 121b to which the first and second electromagnet switch sensors 122 and 123 are attached and the sensor driving module 110 cannot be provided to face each other, and an operation error of the first and second electromagnet switch sensors 122 and 123 may be induced, therefore, the setting angle of the fixing frame 121 needs to be adjusted after the fixing frame 121 is set, resulting in an increase in installation time of the flat bed height sensor module 120.
Therefore, according to the elevator leveling height adjusting system 100 of the embodiment of the present invention, the installation angle fixing part 123 is extended and bent at the upper end of the fixing part 121a to be supported by the side surface part of the car lower frame 310, and even if the fixing member 124 such as a bolt and a nut is rotated to fix the fixing part 121a to the lower surface of the car lower frame 310, the installation angle fixing part 123 is supported by the side surface part of the car lower frame 310, and thus it is possible to prevent the fixing part 121a from being rotated by the rotational force of the fixing member 124 such as a bolt and a nut which fixes the fixing part 121a to the lower surface of the car lower frame 310.
Therefore, according to the flat bed height sensor module 120 of the safety flat bed height adjusting system 100 for an elevator according to an embodiment of the present invention, as long as the sensor driving module 110 is installed on the lower surface of the car lower frame 310 together with the fixing frame 121 through the fixing member 124, even if the installation angle of the fixing frame 121 is not corrected, the flat bed height sensor module 120 is installed in such a manner that the first and second electromagnet switching sensors 122 and 123 always face the sensor driving module 110, and thus the flat bed height sensor module 120 can be installed quickly and easily.
In addition, the flat bed height sensor module 120 may further include a permanent magnet switch sensor 125.
The permanent magnet switch sensor 125 may be disposed on the fixed frame 121 so as to be located between the first and second electromagnet switch sensors 122 and 122123.
When a power failure occurs and the standby power is supplied only to the driving part of the elevator car 300 and the first and second electromagnet switch sensors 122 and 123 stop operating due to no power supply being supplied to the floor leveling sensor module 120, if the car 300 is raised and lowered based on the standby power and the floor leveling sensor module 120 faces the sensor driving module 110, the permanent magnet switch sensor 125 is driven by the magnetic force of the permanent magnet driving part 112 of the sensor driving module 110 as described above, generates an emergency floor leveling height adjustment completion signal, and transmits the emergency floor leveling height adjustment completion signal to the control part 130.
Further, the flat bed height sensor module 120 may further include an end of height adjustment warning means 126.
If the permanent magnet switch sensor 125 transmits an emergency leveling height adjustment completion signal to the control unit 130, the height adjustment completion warning means 126 is driven by the control unit 130 and notifies the manager that the leveling height adjustment of the car 300 is completed.
For example, the height adjustment end warning means 126 is preferably self-powered illumination having a built-in battery.
When the control unit 130 receives the first floor height adjustment completion signal and the second floor height adjustment completion signal, which are sequentially generated from the floor level sensor module 120, it is determined that the floor level adjustment of the car 300, in which the floor of the car 300 and the floor of the landing 200 where the car 300 is to be stopped are kept horizontal, has been completed, and the car 300 being lifted and lowered is stopped.
Referring again to fig. 1 to 3, the operation process and the effect of the application of the safety leveling height adjusting system for an elevator according to an embodiment of the present invention will be described.
Referring to fig. 1 to 3, according to the safety leveling height adjusting system 100 for an elevator according to an embodiment of the present invention, if a user selects to go to a target moving floor, a car 300 ascends or descends along a hoistway 400 and moves to a landing 200 side of the target floor.
If the car 300 moves up or down along the hoistway 400 to the landing 200 side of the target floor and the sensor driving module 110 provided on the landing lower frame 210 is faced with the floor leveling height sensor module 120 provided on the car lower frame 310, the sensor driving module 110 drives the floor leveling height sensor module 120 and sequentially generates a first floor height adjustment completion signal and a second floor height adjustment completion signal.
In more detail, if the car 300 ascends along the hoistway 400 and moves to the landing 200 side of the target floor, the leveling height sensor module 120 ascends together with the car 300 and faces the sensor driving module 110 provided at the landing lower frame 210 of the target floor. That is, if the floor leveling height sensor module 120 ascends together with the car 300 and moves to the landing 200 side of the target floor, the permanent magnet driving section 112 of the sensor driving module 110 faces the first electromagnet switch sensor 122 provided at the upper end of the fixed frame 121, the permanent magnet switch sensor 125 provided at the central portion of the fixed frame 121, and the second electromagnet switch sensor 123 provided at the lower end of the fixed frame 121 in this order.
Therefore, if the floor leveling height sensor module 120 ascends together with the car 300 and moves to the landing 200 side of the target floor, the first electromagnet switching sensor 122, which is first opposite to the permanent magnet driving part 112, is driven by the permanent magnet driving part 112 to generate a first floor height adjustment completion signal and transmit it to the control part 130, if the flat bed height sensor module 120 further ascends a certain distance together with the car 300, the permanent magnet switch sensor 125 is driven by the permanent magnet driving part 112, and generates an emergency flat bed height adjustment completion signal and transmits it to the control part 130, if the flat bed height sensor module 120 further ascends a certain distance together with the car 300, the second electromagnet switching sensor 123 faces the permanent magnet driving part 112 and is driven by the permanent magnet driving part 112 to generate a second floor height adjustment end signal and transmit it to the control part 130.
As described above, if the first and second electromagnet switch sensors 122 and 123 are driven based on the permanent magnet driving part 112 and transmit the first and second floor height adjustment completion signals to the control part 130, the control part 130 determines that the floor height adjustment of the car 300 has been completed to stop the ascending car 300 so that the floor of the car 300 is maintained horizontal with the floor of the landing 200 where the car 300 is to be stopped.
Further, if the car 300 moves down along the hoistway 400 and moves to the landing 200 side of the target floor, the floor leveling height sensor module 120 moves down together with the car 300 and faces the sensor driving module 110 provided on the landing lower frame 210 of the target floor. That is, when the floor leveling height sensor module 120 moves down together with the car 300 to the landing 200 side of the target floor, the second electromagnet switch sensor 123 provided at the lower end of the fixed frame 121, the permanent magnet switch sensor 125 provided at the center of the fixed frame 121, and the first electromagnet switch sensor 122 provided at the upper end of the fixed frame 121 face the permanent magnet driving section 112 of the sensor driving module 110 in this order.
Therefore, if the floor leveling height sensor module 120 ascends together with the car 300 and moves to the landing 200 side of the target floor, the second electromagnet switching sensor 123, which is first faced with the permanent magnet driving part 112, is driven by the permanent magnet driving part 112 to generate a first floor height adjustment completion signal and transmit it to the control part 130, if the flat bed height sensor module 120 further ascends a certain distance together with the car 300, the permanent magnet switch sensor 125 is driven by the permanent magnet driving part 112 to generate an emergency flat bed height adjustment end signal and transmit it to the control part 130, if the flat bed height sensor module 120 further ascends a certain distance together with the car, the first electromagnet switching sensor 122 faces the permanent magnet driving part 112 and is driven by the permanent magnet driving part 112 to generate a second floor height adjustment end signal and transmit it to the control part 130.
As described above, if the second electromagnet switch sensor 123 and the first electromagnet switch sensor 122 are driven based on the permanent magnet driving part 112 and transmit the first leveling completion signal and the second leveling completion signal to the control part 130, the control part 130 determines that the leveling of the car 300 has been completed to stop the ascending car 300 so that the floor of the car 300 is kept level with the floor of the landing 200 where the car is to be stopped.
Further, if a power failure occurs during the operation of the elevator and power cannot be supplied to the elevator, the car 300 stops, and if the car 300 stops due to the power failure as described above, passengers on the car 300 should be safely evacuated from the car 300 to the landing 200.
As described above, if the car 300 is stopped in a state where the floor of the landing 200 and the floor of the car 300 are kept horizontal and the floor height of the car 300 is aligned when a power failure occurs, the manager can open the landing 200 door and the car 300 door and easily evacuate passengers riding in the car 300, but if the car 300 is stopped between the landing 200 and the landing 200, in order to evacuate the passengers riding in the car 300, the passengers can be safely evacuated from the car 300 to the landing 200 side only when the car 300 is raised to the closer landing 200 side by supplying the backup power to the elevator and then the doors of the car 300 and the landing 200 are opened.
However, even if a backup power is supplied to the elevator and the backup power is shared to the driving part for lifting the car 300 so that the manager can manually lift the car 300 when a power failure occurs, since the power is not shared to the flat height adjustment system 100, even if the manager lifts the car 300 to the near landing 200 side, it is not possible to determine whether the flat height of the car 300 is accurately adjusted, and it is very difficult to accurately align the height of the car 300 manually, and thus there is a problem that passengers cannot be saved for a general manager who does not have expert knowledge.
That is, in the elevator, since it is designed that the doors of the car 300 can be opened only when the floor height of the car 300, which keeps the floor of the landing 200 horizontal to the floor of the car 300, is accurately aligned for the sake of safety as a whole, if the floor height of the car 300, which keeps the floor of the landing 200 horizontal to the floor of the car 300, is not accurately aligned, the landing 200 doors and the car 300 doors cannot be opened, and since the floor height adjustment system 100 stops operating at the time of power failure, if the car 300 stops at the middle of the landing 200 and the landing 200 at the time of power failure, even if the manager manually moves the car 300 to the landing side of the landing, the floor height of the car 300 cannot be adjusted so that the floor of the car 200 reached and the floor of the car 300 are kept horizontal near the floor of the landing 200, and the doors of the car 300 cannot be opened, and thus, for a general manager who does not have expert knowledge, passengers cannot be rescued.
In this case, the passengers can be rescued only by requesting a professional rescue team such as 119 rescue team member to move, opening the landing 200 door and then forcibly opening the car 300 door or the rescue team member climbs to the upper part of the car 300 and opens an emergency exit (not shown) at the upper part of the car 300, and if the passengers are rescued in this way, the rescue team member and the passengers are exposed to the elevator shaft 400 where safety accidents frequently occur, so that the work of rescuing the passengers becomes very difficult and time-consuming, and there is always a danger associated with the safety accidents.
However, in the case of an elevator provided with the safety leveling height adjusting system 100 for an elevator according to an embodiment of the present invention, even if a power failure occurs and the car 300 is brought to an emergency stop between the landing 200 and the system 100 for adjusting the leveling height is stopped, if the administrator manually moves the car 300 to the near landing 200 side and causes the leveling height sensor module 120 provided in the car 300 to face the sensor driving module 110 provided in the landing lower frame 210, the permanent magnet switch sensor 125 of the leveling height sensor module 120 is driven based on the permanent magnet driving section 112 of the sensor driving module 110, generates an emergency leveling height adjustment end signal, and transmits the emergency leveling height adjustment end signal to the control section 130, and the control section 130 immediately drives the height adjustment end alarm means 126 upon receiving the emergency leveling height adjustment end signal, and informs the manager that the leveling height adjustment of the car 300 has ended, thereby enabling the manager to know the fact that the leveling height adjustment of the car 300 has ended.
Therefore, in the elevator provided with the safe leveling height adjusting system 100 for an elevator according to an embodiment of the present invention, even if a general manager who does not have expert knowledge stops the car 300 between the landing 200 and the landing 200 in an emergency when a power failure occurs, the car 300 can be moved to the near landing 200 manually with great ease, and the landing 200 door and the car 300 door are opened after the leveling height of the car 300 is adjusted, so that passengers in the car 300 can be rescued quickly and safely.
As described above, according to the safe leveling height adjusting system 100 for an elevator according to an embodiment of the present invention, the sensor driving module 110 is provided in the lower frame 210 of each landing prepared on each floor of the building, the leveling height sensor module 120 is provided in the lower frame 310 of the car, and if the car 300 is moved to the landing 200 of the target floor and the lower frame 210 and the lower frame 310 of the car are kept horizontal, the leveling height sensor module 120 is automatically driven based on the sensor driving module 110 to generate the leveling height adjustment completion signal, and the car 300 being lifted is stopped based on the control unit 130.
Therefore, in the case of the elevator provided with the safe leveling height adjusting system 100 for an elevator according to an embodiment of the present invention, as long as the car 300 is operated after performing the work of disposing the leveling height sensor module 120 to the car lower frame 310 and the work of disposing the sensor driving module 110 to the landing lower frame 210 prepared on each floor of the building, the car 300 is automatically aligned with the leveling height of each landing 200 prepared on each floor of the building and stopped, and after disposing the leveling height adjusting system 100, it is not necessary to additionally perform the work of adjusting the leveling height of the car 300 for each floor, which requires a large amount of work time and is complicated, so that the installation time and maintenance cost of the elevator can be greatly reduced.
In addition, according to the safe leveling height adjusting system 100 for an elevator according to an embodiment of the present invention, the upper end of the fixing frame 111 of the sensor driving module 110 is provided with the installation angle fixing part 113 for supporting the side surface part of the landing lower frame 210, and the upper end of the fixing frame 121 of the leveling height sensor module 120 is provided with the installation angle fixing part 123 for supporting the side surface part of the car lower frame 310, even if the sensor driving module 110 and the leveling height sensor module 120 are rotatably fixed to the landing lower frame 210 and the car lower frame 310 by the fixing members 114 and 124 such as bolts and nuts, respectively, since the installation angle fixing part 113 of the sensor driving module 110 and the installation angle fixing part 123 of the leveling height sensor module 120 are supported on the side surface part of the landing lower frame 210 and the side surface part of the car lower frame 310, respectively, the sensor driving module 110 and the floor height sensor module 120 are prevented from being rotated by the rotational force of the fixing members 114, 124 such as the bolts and nuts.
Therefore, according to the sensor driving module 110 and the floor height sensor module 120 of the safety leveling height adjusting system 100 for an elevator according to an embodiment of the present invention, as long as the fixing frames 111 and 121 are respectively provided to the landing lower frame 210 and the car lower frame 310 by the fixing members 114 and 124, even if the installation angle of the fixing frames 111 and 121 is not corrected, the permanent magnet driving part 112 can be always faced with the first electromagnet switch sensor 122, the second electromagnet switch sensor 123, and the permanent magnet switch sensor 125 by accurately and quickly providing the sensor driving module 110 and the floor height sensor module 120 at accurate positions, and thus the installation work time can be greatly reduced.
Further, according to the safety leveling height adjusting system 100 for an elevator in accordance with an embodiment of the present invention, even if power cannot be shared due to power failure, the permanent magnet switching sensor 125 of the leveling height sensor module 120 is driven by the permanent magnet driving part 112 of the sensor driving module 110 to generate an emergency leveling height adjustment end signal and transmit the emergency leveling height adjustment end signal to the control part 130, and the control part 130 drives the height adjustment end warning means 126 to be driven and informs the manager that the leveling height adjustment of the car 300 has been ended.
Therefore, the elevator provided with the safe leveling height adjusting system 100 for an elevator according to an embodiment of the present invention has an advantage that even if a general manager who does not have expert knowledge stops the car 300 between the landings 200 and 200 in an emergency when a power failure occurs, the car 300 can be moved to the near landings 200 manually with great ease, and the landing 200 doors and the car 300 doors are all opened after adjusting the leveling height of the car 300, so that passengers in the car 300 can be quickly and safely moved to the landing sides and safely rescued.
