The present application claims priority from korean patent application No. 10-2019-0144559, filed on 12/11/2019, the specification of which and the drawings of which disclose all matters contained therein.
Technical Field
The present invention relates to an intelligent high-place installation apparatus lifting device and a control method thereof, and more particularly, to an intelligent high-place installation apparatus lifting device having a structure for lifting a high-place installation apparatus installed at a high place by winding or unwinding a wire rope on a drum, and a control method thereof.
Background
Generally, ceiling lights of hotel halls and factories, and street lights of gymnasiums and roads are installed with so-called high illumination lamps. The high-altitude illumination lamp is mainly provided with a sodium bulb and a mercury bulb, and the service life of the high-altitude illumination lamp is limited to about 5000-6000 hours, so the high-altitude illumination lamp needs to be replaced regularly. In addition, high-place illumination lamps installed in service companies such as hotel lobbies, auditoriums, etc. need to be periodically cleaned and bulb-replaced for aesthetic appearance and exhibition effects.
Taking a street lamp as an example, the height of the high-place illuminating lamp is 7-10 m, and the high-place illuminating lamp is positioned at a high place, so that a crane or an aerial ladder truck with a hanging basket for high-place operation is used for cleaning and replacing bulbs of the high-place illuminating lamp. In addition, in places such as the low auditorium of height and hotel lobby, carry out the cleanness and the change of bulb through placing the ladder, there is accident risk such as falling under this kind of condition. In addition, at least more than 3 persons are needed for work, and large-scale working facilities such as cranes, aerial ladder vehicles and the like are adjusted to high-altitude illuminating lamp working places, so that the working time is delayed, and the working space is occupied. Therefore, when the high illumination lamp is repaired and replaced, the factory production line and the gymnasium need to be stopped for a long time, and the work must be completed quickly, which is difficult. In particular, the crane occupies a lane when maintaining the street lamp, thereby causing traffic jam and other problems.
As an alternative, efforts have been made to develop a method and an apparatus for operating a high-altitude illumination lamp, which can lower the high-altitude illumination lamp to the ground where a maintenance worker is located for maintenance and then raise the high-altitude illumination lamp to be fixed to the ceiling, without raising the high-altitude illumination lamp to the location where the high-altitude illumination lamp is located.
As devices capable of lowering a high-altitude illumination lamp installed on a ceiling to the ground as described above: the manual lifting device of the high illumination lamp is characterized in that a steel wire rope is fixed on the illumination lamp, the steel wire rope passes through a ceiling and is wound on a pulley fixed on the ground, a user lifts the high illumination lamp by operating a handle connected with the pulley, and the automatic lifting device of the high illumination lamp replaces the handle by a driving motor.
In general, an automatic lifting device for a high illumination lamp includes a socket part (body) fixed at a predetermined height on a ceiling side, a lamp (lifting body) inserted into a contact of the adjustment part and connected to the lamp, the lamp having a bulb mounted on a lower side thereof, a wire rope having one end fixed to an upper side of the lamp and the other end wound around a reel provided at a predetermined position of the socket part, and a driving motor for automatically unwinding or winding the wire rope on the reel according to a user's selection to lift the lamp.
For example, korean patent laid-open No. 10-1056847 discloses a technology related to the construction of an automatic lifting device for a high-altitude illumination lamp in which a wire rope is unwound and wound. The high illumination lift apparatus of korean granted patent No. 10-1056847 is disclosed to include: the reel is in a structure of standing state in the body by a drive switch which is pressed by the sensing plate to stop the operation of a drive device for driving the reel to rotate when the sensing plate is pushed out to a set position along with the increase of the number of the layers of the steel wire rope wound on the reel.
However, according to the prior art, when a power abnormality such as a Short circuit (Short) occurs in a specific high illumination lamp among a plurality of high illumination lamps installed in a facility and a breaker is opened, even if the breaker is closed and the power is recovered, the breaker is still opened because the high illumination lamp is in a Short circuit state. Therefore, there is a problem that all of the plurality of high-altitude illumination lamps, which are powered on/off by the circuit breaker, cannot operate.

The center of the lower contact portion 202 may be provided with a through-hole 205 for the passage of the wire rope 1.
It is preferable that a plurality of microcomputers 300 are provided in one-to-one correspondence with a plurality of high-place installation apparatuses 10. Preferably, the microcomputer 300 may be built in the body 100.
Immediately after the breaker 301 is turned Off (Off), the control unit 300a in the microcomputer 300 confirms whether the high-altitude installation apparatus 10 has power abnormality and stores the power abnormality information in the memory 300 b. Then, when the breaker 301 is turned back to the On (On) state, the control unit 300a of the microcomputer 300 checks the power abnormality information of the high-place mounted apparatus 10 stored in the memory 300b, turns the relay 304 to the Off (Off) state to cut Off the power supply to the high-place mounted apparatus 10 in which the power abnormality information is stored, and at the same time, turns the relay 304 to the On (On) state to supply the power to the high-place mounted apparatus 10 in which the power abnormality information is not stored. That is, among the plurality of high-altitude mounted apparatuses 10, the high-altitude mounted apparatus 10 in which the power abnormality such as the overcurrent occurs due to the overvoltage, the short circuit, or the like is turned Off (Off) by the relay 304 by the microcomputer 300, and the power is turned Off, and the high-altitude mounted apparatus 10 in which the power abnormality does not occur is supplied with the power because the relay 304 is turned On (On) by the microcomputer 300.
As power is supplied to the high-place attachment apparatus 10, the high-place attachment apparatus 10 becomes in a standby state. In the case where the high-place mounted apparatus 10 corresponds to an illumination lamp in the standby state, the illumination lamp is turned on when the administrator performs a switching operation of turning on the high-place mounted apparatus 10 by using a remote controller (see 11 of fig. 7) or the like.
An accumulator 303 capable of supplying an emergency power to the microcomputer 300 for a predetermined time period, for example, about 1 to 2 seconds, immediately after the breaker 301 is turned off is connected to the microcomputer 300. Therefore, the microcomputer 300 can perform a work of confirming whether the high-altitude installation apparatus 10 is abnormal in power immediately after the breaker 301 is opened and storing the state information to the memory 300 b.
The circuit breaker 301 is a device that opens and closes an electric power system, and automatically opens when a Short circuit (Short) occurs to cut off power supplied to a plurality of high-mounted devices 10 connected thereto. The circuit breaker 301 may be configured to collectively turn on and off the power supply to a plurality of high-altitude installation apparatuses 10 provided in a predetermined facility object, or may be configured by grouping a predetermined number (for example, about 10) of high-altitude installation apparatuses 10 and arranging them in groups.
Fig. 3 to 5 show a process of performing a control method of an intelligent high-mount apparatus lifting device of a preferred embodiment of the present invention.
First, referring to fig. 3, the microcomputer 300 starts activation when the breaker 301 turns On (On) the input power, and the relay 304 turning On (On) the power operates according to the driving control of the microcomputer 300, thereby supplying the power to the high mount apparatus 10 corresponding to the microcomputer 300 (steps S100 to S102).
Thereafter, the breaker 301 is automatically opened in the case where a short circuit occurs in a specific apparatus, i.e., the high-place installation apparatus 10, for a predetermined reason (steps S103 and S104).
Immediately after the breaker 301 is turned Off, the microcomputer 300 senses and recognizes an Off state of the power supply and an overcurrent caused by a short circuit by the emergency power operation of the capacitor 303, and stores the state information in the memory 300b (steps S105 and S106). The power abnormality sensing unit 302 is a current sensor. Microcomputer 300 obtains the overcurrent sensing signal input from power abnormality sensing section 302 and recognizes a power abnormality caused by the occurrence of a short circuit in high-mounted apparatus 10 corresponding thereto.
When the circuit breaker 301 is turned on again after the circuit breaker 301 is opened to re-input the power (step S107), the microcomputer 300 starts, checks the state information about whether or not the short circuit is stored in the memory 300b, and performs the driving control of the relay 304 connected to the high-altitude installation apparatus 10 (steps S108 and S109). For example, when the memory 300b stores information indicating that the high-mounted apparatus 10 is in a state in which an electrical power abnormality (overcurrent) occurs due to a short circuit, the microcomputer 300 cuts off the operation of the relay 304 to cut off the supply of power to the high-mounted apparatus 10. Therefore, the breaker 301 is not turned off again by the high-altitude mounted equipment 10 in which the short circuit occurs, and the high-altitude mounted equipment 10 in which the short circuit does not occur is normally supplied with power, and waits for a power-On (On) signal for a lowering operation and equipment start-up (step S110).
In addition, fig. 4 shows a process of confirming that the power abnormality occurs due to the overvoltage at a high place where the apparatus 10 is installed. The power abnormality sensing unit 302 is a voltage sensor. In this case, the microcomputer 300 recognizes that the breaker 301 is abnormally operated when the manager re-closes the breaker 301 after the initial opening of the breaker 301 to turn the breaker 301 to the On (On) state and the breaker 301 is instantaneously switched to the off state again due to the power abnormality. Therefore, the microcomputer 300 confirms whether the high-mounted equipment corresponding thereto is over-voltage or not immediately after the breaker 301 is opened and stores the power abnormal state information in the memory 300b to recognize the power abnormal state. In this case, it is possible to confirm which high-altitude installation apparatus 10 has the power abnormality by sequentially activating the plurality of high-altitude installation apparatuses 10 whose power sources are turned on and off by the same breaker 301 one by one.
Specifically, in the standby state of the input power supply lowering operation and the On (On) signal for starting the device (step S110), a process of selecting one of the plurality of lifting devices to start the device is sequentially executed (step S111).
When the administrator operates the remote controller 11 or the like and senses a signal for lowering the elevating body 200, the microcomputer 300 performs a driving control for activating the relay 304 connected to the high-place mounting apparatus 10 (steps S112 and S113).
When the power abnormality occurs due to the overvoltage in the high-place installation equipment 10, the breaker 301 is opened (steps S114 and S115). After confirming the power abnormality, the microcomputer 300 lowers the ascending/descending body 200 and the high-place installation tool 10 to the ground for confirming the tool (step S116).
Fig. 5 specifically illustrates the process of servicing a short-circuited aerial installation apparatus 10. The microcomputer 300 starts the driving motor 113 disposed in the main body 100 to rotate the drum 101 to lower the ascending/descending body 200 and the high-place installation apparatus 10 to the ground as the administrator operates the remote controller 11 or the like to sense a signal to lower the ascending/descending body 200 (steps S120 and S121). Specifically, the microcomputer 300 releases the engagement of the stopper 106 with the vertically movable body 200, and then rotates the drum 101 in the reverse direction to lower the vertically movable body 200 toward the ground by unwinding the wire rope 1 into the hollow of the drum 101. To release the hooked state of the stopper 106, the drum 101 may be driven to rotate slightly in the forward direction to lift the vertically movable body 200 slightly. Through this process, the stopper 106 is released from the side surface of the lifting body 200 to return to the home position, and thus the lifting body 200 can be switched to a freely-lowerable state.
After the high-place attachment apparatus 10 is repaired, the elevating body 200 is raised again and coupled to the main body 100, and then the high-place attachment apparatus 10 corresponding to, for example, an illumination lamp is turned on (steps S122 and S123). The winding operation of the wire rope 1 is performed by the drum 101 disposed in the main body 100 and rotated in the forward direction by the drive motor 113. Here, the wire rope 1 is pulled up while passing through the hollow of the drum 101, and then is wound around the drum 101 with the direction thereof changed by the guide roller 103.
When the lifting body 200 is lifted up to a predetermined position by the winding of the wire rope 1, the arrival state is sensed by a predetermined limit switch (not shown), the rotation of the drum 101 is stopped in response to the sensing signal, and the hanging base 201 provided at the upper end of the outer peripheral surface of the lifting body 200 is caught by the stopper 106 protruding from the inner wall of the housing member 105 of the coupling portion 104, so that the lifting body 200 is fixed to the main body 100.
The lifter 200 is inserted into and fixed to the housing member 105, and the upper contact portion 109 and the lower contact portion 202 are brought into contact with each other to be energized.
The configuration and control method of the intelligent high-place mounted equipment lifting device described above are preferably applied to a case where the high-place mounted equipment 10 is an illumination lamp installed on a ceiling inside a facility, as shown in fig. 6 and 7. Alternatively, as shown in fig. 8 and 9, the present invention may be applied to a case where the high-place installation equipment 10 is a ventilation fan installed in a ceiling inside the facility.
As described above, the microcomputer 300 of the intelligent high-altitude installation apparatus lifting device of the present invention recognizes the specific high-altitude installation apparatus 10 in the abnormal state of power and performs the power supply cutoff control, and thus can solve the problem that the entire circuit is repeatedly opened when the breaker 301 is closed again.
The present invention has been described above by way of the embodiments defined in the drawings, but the present invention is not limited thereto, and it will be apparent to those skilled in the art to which the present invention pertains that various modifications and variations can be made within the technical spirit of the present invention and the scope of the appended claims.
