Technical Field

Background

In general, street lamps on ceilings of hotel lobbies and factories and on gyms and roads are equipped with so-called overhead lighting lamps. The high-place illuminating lamp is mainly provided with a sodium bulb and a mercury bulb, and the service life of the high-place illuminating lamp is limited to about 5000-6000 hours, so that the high-place illuminating lamp needs to be replaced periodically. In addition, for aesthetic and display effects, the lamps installed at the high places of service companies such as hotel lobbies and auditoriums need to be cleaned and replaced at regular intervals.

In the case of street lamps, the height of the overhead lighting lamp is 7-10 m, and since the street lamps are located at a high position, the street lamps are operated by using a crane or an aerial ladder truck equipped with a hanging basket for cleaning and replacing bulbs of the overhead lighting lamp. In addition, in places such as auditoriums and hotel lobbies with lower heights, the lamp bulbs are cleaned and replaced by placing ladders, and under the conditions, the risks of accidents such as falling exist. In addition, the work must be carried out by at least more than 3 persons, and large working facilities such as a crane, a stair car and the like are adjusted to a high-place illuminating lamp workplace, so that the working time is delayed, and the working space is occupied. Therefore, when the high-altitude illumination lamp is maintained and replaced, the factory production line and the gym are required to be stopped for a long time, so that the work is required to be completed rapidly, and the difficulty is caused. In particular, the crane occupies a lane when the street lamp is maintained, so that problems such as traffic jam and the like can be caused.

As an alternative, there has been an effort to develop a high-place lamp operating method and operating apparatus that can lower the high-place lamp to the ground where a serviceman is to repair it without lifting up to the place where the high-place lamp is located, and then lift it up to fix it on the ceiling.

As means for lowering the overhead lighting lamp mounted on the ceiling to the ground as described above, there are: the manual lifting device is characterized in that a steel wire rope is fixed on the illuminating lamp, the steel wire rope passes through a ceiling and is wound on a pulley fixed on the ground, a user lifts the overhead illuminating lamp of the overhead illuminating lamp by operating a handle connected with the pulley, and the automatic lifting device uses a driving motor to replace the handle.

Generally, an automatic lifting device for a high-altitude illumination lamp includes a socket part (body) fixed at a predetermined height on a ceiling side, a lamp (lifting body) inserted into a contact connection of the adjusting part and having a bulb mounted at a lower side thereof, a wire rope having one end fixed at an upper side of the lamp and the other end wound on a drum provided at a certain position of the socket part, and a driving motor for automatically unwinding or winding the wire rope on the drum according to a user's selection to lift the lamp.

For example, korean patent No. 10-1056847 discloses a technology related to the construction of unwinding and winding a wire rope in an automatic lifting device for a head lamp. The high-altitude illumination lifting device of korean patent No. 10-1056847 discloses a high-altitude illumination lifting device comprising: and a driving switch which is pressed by the sensing plate to stop the driving device for driving the winding drum to rotate when the sensing plate is pushed out to a set position along with the increase of the number of the steel wire rope layers wound on the winding drum, wherein the winding drum is in an upright state in the body.

However, according to the related art, in case that a circuit breaker is opened due to an abnormal power such as a Short circuit (Short) occurring in a specific high-altitude lamp among a plurality of high-altitude lamps installed in a facility, even if the circuit breaker is powered on again, the problem that the circuit breaker is still opened because the high-altitude lamp is in a Short-circuited state is caused. Therefore, there is a problem in that all of the plurality of overhead lighting lamps turned on/off by the circuit breaker are not operated.

Referring to fig. 1 and 2, the intelligent high-altitude installation equipment lifting device includes: the power supply device comprises a body 100 provided at a high position of a predetermined height and having a drum 101 provided therein, a coupling part 104 provided at a lower part of the body 100, a lifting body 200 suspended from a wire rope 1 wound around the drum 101 and having a device coupling part 204 provided at a lower end thereof, the lifting body 200 being lifted up to be coupled to the body 100 via the coupling part 104, an upper contact part 109 and a lower contact part 202 contacting each other, a circuit breaker 301 having an opening/closing function for operating the high-altitude mounting device 10 and for lifting/lowering driving power, and a microcomputer 300 for controlling On/Off (Off) of a power supply supplied to the high-altitude mounting device 10 based On power abnormality information stored in a memory 300b.

The body 100 is provided at a high position of a predetermined height at an upper end of a supporting object such as a building ceiling, a street lamp, or the like. For mounting the body 100, the upper end of the body 100 is provided with a mounting member 111 constituted by, for example, an annular bolt. Alternatively, the body 100 may be connected to a predetermined support bracket (not shown) that can be coupled to a predetermined H-beam provided at a ceiling of a building or the like.

The main body 100 has therein a spool 101 around which the wire rope 1 can be wound and a drive motor 113 for supplying a rotational force in the forward and reverse directions to the spool 101. It is preferable that the driving motor 113 employs a Geared motor (Geared motor).

The spool 101 is a cylindrical wire barrel capable of winding and unwinding the wire rope 1. The spool 101 is preferably rotatably provided in the body 100 in a state of being laid down with a substantially vertical opening with respect to the ground. As an alternative, the spool 101 may also be disposed upright within the body.

In order to function as a medium for coupling between the body 100 and the elevating body 200, the lower portion of the body 100 has a coupling portion 104 formed with a hollow receiving member 105.

The coupling part 104 is located at the lower portion of the body 100 and serves as a medium that enables the elevating body 200 to be coupled to an accurate position of the body 100 when it is elevated to a predetermined place by the winding of the wire rope 1. Specifically, the coupling portion 104 includes a predetermined-shaped housing member 105 for guiding the elevating body 200 to be arranged at the lower portion of the center of the main body 100, and a stopper 106 for fixing the coupled state of the elevating body 200 to the main body 100.

The housing member 105 is configured in a cylinder shape having an open lower portion and having an internal space in which at least an upper portion of the elevating body 200 can be moved in and out. The receiving member 105 may be integrally formed with the body 100, and alternatively, may be configured as a separate component from the body 100 and detachably coupled to the lower portion of the body 100.

The housing member 105 is located in the hollow of the spool 101 disposed in the body 100. That is, the spool 101 is arranged in a shape substantially surrounding the housing member 105. According to this structure, the hollow of the spool 101 can be used as a space for coupling between the body 100 and the elevating body 200.

The anti-friction roller 107, which is in contact with the inner peripheral surface of the spool 101, is rotatably provided in a space between the housing member 105 and the spool 101, and serves to guide the rotation of the spool 101 in a horizontal state.

In order to improve the coupling accuracy between the body 100 and the elevating body 200, a guide groove 108, which is located on the outer periphery of the housing member 105 and substantially surrounds in a circular shape, is formed on the lower surface of the body 100. The guide groove 108 is engaged with a guide projection 203 provided on the lifter 200 when the lifter 200 is engaged with the housing member 105, and serves to guide the lifter 200 to be engaged with the main body 100 at the normal position.

The stopper 106 is provided to protrude from an inner wall surface of the housing member 105 to fix a position of the elevating body 200 inserted into the housing member 105. A plurality of stoppers 106 are provided at equal intervals in the circumferential direction with reference to the center of the housing member 105.

The stopper 106 is provided as a body having a wedge shape inclined downward, and is always maintained in a horizontal state when no external force is applied. The stopper 106 is provided so as to be rotatable about an axis coupled to a part of the main body, and is pushed away and turned upward when the lifting body 200 is lifted. The stopper 106 incorporates a predetermined spring (not shown) that elastically deflects (bias) so as to be able to return to a horizontal state. The stopper 106 may also be selectively projected from the inner wall surface of the housing member 105 by a driving mechanism such as a solenoid in the present invention.

The lifting body 200 is configured to be suspended from the wire rope 1 and lifted and lowered simultaneously with winding up and winding down of the wire rope 1. The lower end of the lifting body 200 is provided with a device coupling portion 204 constituted by, for example, an annular bolt. The device coupling portion 204 may be any structure or component that can support the high-mounted device 10. For example, the device coupling portion 204 may be configured as a screw structure capable of being screw-coupled with the high-mounted device 10. The equipment joining portion 204 may be formed of another component or may be integrated with a local portion of the lifting body 200.

The device coupling portion 204 is coupled with a high-mounted device 10 such as an illumination lamp, a ventilator, a closed circuit television Camera (CCTV Camera), or the like. The high-mounted device 10 is not limited to an illumination lamp, a ventilator, a CCTV camera, etc., but may employ other various high-mounted electronic/electric devices.

A hooking base 201 corresponding to the stopper 106 is formed at the upper end of the outer peripheral surface of the elevating body 200. When the lifting body 200 is lifted, the hooking base 201 lifts the rotation stopper 106, and the groove portion and the stopper 106 are combined to fix the position of the lifting body 200.

The wire rope 1 unwound from the drum 101 passes through the hollow of the drum 101 and extends to the lower portion to be connected to the elevating body 200. For this purpose, a plurality of guide rollers 103 for guiding the wire rope 1 unwound from the drum 101 into the hollow interior of the drum 101 are disposed at the side and upper portions of the drum 101. The guide roller 103 located at the upper portion of the roll 101 among the plurality of guide rollers 103 is mounted to a guide frame 102 disposed inside the body 100 so as to cross the upper portion of the roll 101.

The arrangement structure of the wire ropes 1 is a single wire type, that is, when the wire ropes 1 passing through the drum 101 are hollow, at least one guide roller 103 among the plurality of guide rollers 103 is disposed at a position capable of guiding the wire ropes 1 toward the midpoint of the drum 101.

In addition, the arrangement structure of the wire ropes 1 is a double wire type, that is, when there are two hollow wire ropes 1 passing through the drum 101, the wire ropes 1 pass through both sides of the drum 101 at a distance equal to or greater than a predetermined distance from the center.

The upper contact portion 109 and the lower contact portion 202 are provided at the lower portion of the body 100 and the upper portion of the lifter 200, respectively, and the body 100 and the lifter 200 are combined to be in contact with each other to be energized. Specifically, the upper contact portion 109 is fixed to an upper portion of the housing member 105 of the coupling portion 104 disposed in the inner region of the spool 101. The center of the upper contact portion 109 may have a through hole 110 for the wire rope 1 to pass through.

The lower contact portion 202 is fixed to the upper end of the lifter 200, and the housing member 105 inserted into the coupling portion 104 contacts the upper contact portion 109 when the body 100 is coupled to the lifter 200. That is, the upper contact portion 109 and the lower contact portion 202 substantially contact each other in the hollow inner region of the spool 101. The center of the lower contact portion 202 may be provided with a through hole 205 for the wire rope 1 to pass through.

It is preferable that a plurality of microcomputers 300 are provided in one-to-one correspondence with a plurality of high-mounted apparatuses 10. Preferably, the microcomputer 300 may be built in the body 100.

The control section 300a in the microcomputer 300 immediately confirms whether or not the high mounted device 10 is power abnormal after the circuit breaker 301 is opened (Off) and stores the power abnormality information to the memory 300b. When the circuit breaker 301 is turned back On (On), the control unit 300a of the microcomputer 300 confirms the power abnormality information of the high-mounted device 10 stored in the memory 300b, turns Off the relay 304 for the high-mounted device 10 storing the power abnormality information to turn Off the power supply, and turns On the relay 304 for the high-mounted device 10 not storing the power abnormality information to supply the power. That is, the relay 304 is turned Off (Off) by the microcomputer 300, and thus the power supply is turned Off, and the high mounted device 10 in which no power abnormality occurs is turned On (On) by the microcomputer 300, and thus the power supply is supplied, from among the plurality of high mounted devices 10, by the high mounted device 10 in which the power abnormality occurs due to the overvoltage, the short circuit, or the like.

As power is supplied to the high mounted device 10, the high mounted device 10 becomes a standby state. In the standby state, when the high mounted device 10 corresponds to an illumination lamp, the administrator performs a switching operation of turning on the high mounted device 10 by using a remote controller (see 11 of fig. 7) or the like, and turns on the illumination lamp.

The microcomputer 300 is connected to a capacitor 303 which can supply emergency power to the microcomputer 300 for a predetermined period of time, for example, about 1 to 2 seconds, immediately after the breaker 301 is opened. Therefore, the microcomputer 300 can perform a work of confirming whether the high mounted device 10 is abnormal in power immediately after the circuit breaker 301 is opened and storing the state information to the memory 300b.

The microcomputer 300 obtains a sensing signal input from the power abnormality sensing portion 302 to identify whether the high mounted device 10 or a circuit connected to the high mounted device 10 is short-circuited. Among them, it is preferable that the power abnormality sensing portion 302 employ a voltage sensor or a current sensor.

The circuit breaker 301 is a device for switching on and off a power system, and is automatically opened to cut off power supplied to a plurality of high-mounted devices 10 connected thereto when a Short circuit (Short) occurs. The circuit breaker 301 may be configured to switch on and off the power supply of a plurality of high-mounted devices 10 provided in a predetermined facility object at a time, or may be configured by grouping the high-mounted devices 10 by a predetermined number (for example, about 10).

Fig. 3 to 5 illustrate a process of performing a control method of the intelligent high-altitude installation apparatus lifting device according to the preferred embodiment of the present invention.

First, referring to fig. 3, when a power is input to a circuit breaker 301 On, a microcomputer 300 starts to activate, and a relay 304 for turning On (On) the power is operated according to a driving control of the microcomputer 300, thereby supplying power to the high mounted device 10 corresponding to the microcomputer 300 (steps S100 to S102).

Thereafter, the circuit breaker 301 is automatically opened in the case where a short circuit occurs in a specific device, i.e., the high mounted device 10, for a predetermined reason (steps S103 and S104).

Immediately after the breaker 301 is opened, the microcomputer 300 operates with the emergency power supply of the accumulator 303, senses and recognizes a power-Off (Off) state and an overcurrent due to a short circuit, and stores the state information thereof in the memory 300b (steps S105 and S106). The power abnormality sensing unit 302 is constituted by a current sensor. The microcomputer 300 obtains the overcurrent sensing signal input from the power abnormality sensing section 302 and recognizes that the short circuit has occurred in the high-mounted device 10 corresponding thereto.

When the circuit breaker 301 is turned off and then the circuit breaker 301 is turned on again to re-input the power (step S107), the microcomputer 300 is started up, confirms the state information about whether or not the short circuit is stored in the memory 300b, and performs driving control of the relay 304 connected to the high mounted device 10 (steps S108 and S109). For example, when the memory 300b stores information indicating that the high-mounted device 10 is in a state in which an abnormal power (overcurrent) occurs due to a short circuit, the microcomputer 300 cuts off the operation of the relay 304 to cut off the power supply to the high-mounted device 10. Therefore, the circuit breaker 301 does not re-turn off by the high mounted device 10 in which the short circuit has occurred, and the high mounted device 10 in which the short circuit has not occurred is normally supplied with power, and waits for a lowering operation and a power On (On) signal for device startup (step S110).

In addition, fig. 4 shows a process of confirming the high-mounted device 10 in which the power abnormality occurs due to the overvoltage. Wherein the power abnormality sensing portion 302 is constituted by a voltage sensor. In this case, the microcomputer 300 recognizes that the circuit breaker 301 is in an On (On) state by the manager re-closing the circuit breaker 301 after the circuit breaker 301 is initially opened, and when the circuit breaker 301 is instantaneously switched to an off state again due to an abnormal power, it is recognized as an abnormal operation. Accordingly, the microcomputer 300 confirms whether or not the high mounted device corresponding thereto is over-voltage immediately after the circuit breaker 301 is opened and stores the power abnormality state information in the memory 300b to identify the power abnormality state. In this case, by sequentially activating the plurality of high-mounted apparatuses 10 whose power supply is turned on and off by the same circuit breaker 301, it is possible to confirm which high-mounted apparatus 10 has the power abnormality.

Specifically, in a state where the power supply standby operation and the power On (On) signal standby for device startup are inputted (step S110), a process of selecting one of the plurality of lifting devices to start is sequentially executed (step S111).

When the microcomputer 300 senses a signal to lower the elevating body 200 as the manager operates the remote controller 11 or the like, it performs driving control to start the relay 304 connected to the high mounted device 10 (steps S112 and S113).

When an abnormality in power due to overvoltage occurs in the high-mounted device 10, the circuit breaker 301 is opened (steps S114 and S115). After confirming the power abnormality, the microcomputer 300 lowers the lifting body 200 and the high-mounted device 10 to the ground for confirmation of the device (step S116).

Fig. 5 shows in particular the process of repairing a short-circuited high mounted device 10. The microcomputer 300 starts the driving motor 113 disposed in the body 100 to rotate the drum 101 to lower the elevation body 200 and the high mounted apparatus 10 to the ground as the manager operates the remote controller 11 or the like to sense a signal to lower the elevation body 200 (steps S120 and S121). Specifically, the microcomputer 300 releases the state of the stopper 106 being attached to the elevating body 200, and then rotates the spool 101 in the opposite direction to unwind the wire rope 1 from the spool 101 and lower the elevating body 200 up and down. To release the hung state of the stopper 106, the spool 101 may be driven so as to slightly rotate in the forward direction to slightly lift the lifter 200. By this process, the stopper 106 is disengaged from the side surface of the elevating body 200 to return to the original position, and thus the elevating body 200 can be converted into a freely lowerable state.

After the high-mounted device 10 is repaired, the lifting body 200 is raised again and coupled to the main body 100, and then the high-mounted device 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 winding drum 101 disposed in the main body 100 and rotated in the forward direction by the driving motor 113. The wire 1 is pulled up during the hollow process of the spool 101, and then is wound around the spool 101 by the guide roller 103 in the direction change.

When the lifting body 200 rises 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 spool 101 is stopped according to the sensed signal, and the hooking 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 body 100.

The lifting body 200 is inserted and fixed into the housing member 105, and the upper contact portion 109 and the lower contact portion 202 are energized in contact with each other.

As shown in fig. 6 and 7, the configuration and control method of the intelligent high-altitude installation apparatus lifting device described above are preferably applicable when the high-altitude installation apparatus 10 is an illumination lamp provided in a ceiling of a facility. As an alternative, as shown in fig. 8 and 9, the high-mounted device 10 may be applied to a case where the high-mounted device is a ventilator provided in a ceiling inside a facility.

As described above, the microcomputer 300 of the intelligent high-mounted device elevating apparatus of the present invention recognizes the specific high-mounted device 10 in the power abnormal state and performs the power supply cut-off control, and thus can solve the problem of repeated disconnection of the entire circuit when the circuit breaker 301 is closed again.

The present invention has been described above by way of the limiting examples and the accompanying drawings, but the present invention is not limited thereto, and it is apparent that those skilled in the art to which the present invention pertains can make various modifications and variations within the technical spirit of the present invention and the equivalent scope of the appended claims.
