Description

{APPARATUS FOR HOIST FLAG}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device.

In general, national flags symbolize national flags that can be hoisted on the street lamps of various households, government offices and roads to encourage patriotism on various anniversaries such as national holidays. Various banners used for events and festivals are also installed on the roads near the roads of the municipalities, around the festivals or around the event sites, or indoors and outdoors, and are used appropriately to promote the festivities and events.

Since various kinds of flags raised in the outdoors are generally flapping by the wind, the effect of directing is enhanced. For example, in a state where there is little wind, the flags are not flapped and are kept folded by their own weight. There is a problem that the effect of the flag due to the hoisting of the flag is greatly reduced,

In addition, various flags including the national flag are hoisted at various event venues such as political parties, indoor sports events, and festivals held in the hall. In this case, the effect of the flag can not be expected because the wind does not blow there is a problem.

Accordingly, in recent years, a utility model registration No. 20-0400565 (name: a spreading device for flag for flags) has been proposed as a technique for spreading a flags hoisted.

In the prior art of the Utility Model Registration No. 20-0400565, a blowing motor provided with a blade for generating wind while rotating through a motor is built in. The wind generated from the blowing motor is blown by a flag via a hollow portion So that they can maintain the unfolded state of the flag '.

However, since the above-described prior art is configured to generate wind by blowing motors from the lower side and then to send the flag upwards, the blowing motor having a very strong output inevitably must be used in order to spread the flags In this case, a very loud noise is generated, and there is a problem that it can not be used at all in a room.

Particularly, in the case where flags are hoisted on a plurality of separately provided hoists, a plurality of blowing motors must be installed. In this case, there is a serious problem that a loud noise can not be imagined.

In addition, in the prior art, there is no means for detecting the wind speed, and the user must manually operate the wind after detecting the strength of the wind with the naked eye of the manager.

Further, since there is no separate light emitting means for illuminating the flap, there is a problem in that it is not possible to expect a directing effect depending on the flags of the flag at night or in a dark room.

In addition, Korean Patent Registration No. 1508456 discloses that a discharge hole is formed so as to flap a flag, and a flag is provided across the discharge hole. However, a directing force of directing the wind on the side of the flag, .

1 to 3, a gear lift apparatus according to the present invention includes a base unit 10, a rotation unit 20, a lift unit 30, and an injection fan 40.

First, the base portion 10 is installed on the mounting surface.

For example, the base unit 10 may be installed on the ground, and an enclosure may be embedded in the ground to provide an injection fan 40, which will be described later.

Also, the housing may be provided with a control unit including a power supply terminal and a PCB.

The base portion 10 includes the lower plate 11, the upper plate 13, and the shaft rod 17.

The lower plate 11 is located on the upper side of the injection fan 40 and is fixedly installed on the installation surface and has a first through hole 12 through which air to be injected into the injection fan 40 passes.

The upper plate 13 is provided at the upper portion of the lower plate 11 and is fixedly installed. A second through hole 14 communicating with the first through hole 12 is formed. An inner groove 15, .

The upper plate 13 may be formed with a spacing groove 16 which is further inwardly lower than the bottom of the inner groove 15 so as to be spaced apart from the lower end of the bearing 21 described later.

The shaft rod 17 is provided and fixed to the inner groove 15 of the upper plate 13 and has a third through hole 18 communicating with the second through hole 14.

At this time, the diameter of the second through hole 14 is larger than the diameter of the first through hole 12, and the diameter of the third through hole 18 is formed larger than the diameter of the second through hole 14.

The rotating portion 20 is rotatably provided on the upper portion of the base portion 10, and the center thereof is formed to pass through.

That is, the rotating portion 20 includes a bearing 21 and a rotary plate 23.

The bearing 21 is rotatably provided in the third through hole 18 of the shaft rod 17. The upper end of the bearing 21 protrudes more than the upper end of the shaft rod 17 and penetrates vertically, The first insertion hole 22 is formed. At this time, gears may be formed so that the inner circumferential surface of the first insertion hole 22 and the lower outer circumferential surface of the lift base 30 can be engaged with each other.

The reason why the upper end of the bearing 21 is provided so as to protrude more than the upper end of the shaft rod 17 is that the rotary shaft 23 and the shaft rod 17, which will be described later,

The rotary plate 23 is integrally fixed to the upper portion of the bearing 21 and is formed with a second insertion hole 24 into which the lower portion of the lift base 30 is inserted and is separated from the upper end of the shaft rod 17.

The diameter of the rotary plate 23 is larger than the diameter of the shaft rod 17.

The lifting base 30 is provided in the rotary part 20 and is integrally rotated to form an air passage part 31 in which air flows into the inside of the rotating part 20 and moves upward from the lower part.

At this time, the lifting base 30 includes an engaging portion 33 provided at an upper portion of the rotating plate 23 and fixedly coupled to the rotating plate 23.

That is, the lifting base 30 is rotatable integrally with the rotary portion 20, and the air passage portion 31 and the first through hole 12 are communicated with each other to inject air into the air passage portion 31.

Here, the end of the engaging portion 33 of the lifting base 30 is bent downward so as to surround the outer circumferential surface of the rotating plate 23. Accordingly, the engaging portion 33 is formed so as to surround the rotating plate 23, which is larger than the blister, so that foreign matter such as water or dust can be prevented from flowing into the space between the shaft rod 17 and the rotating plate 23 from the outside. This is to prevent the foreign material flowing into the bearing 21 as much as possible, so that the rotation of the lifting base 30 can be smoothly performed.

Here, the lifting base 30 includes a pair of rollers provided on the upper and lower sides, and a wire surrounding the pair of rollers. At this time, the base 32 is hoisted on the wire.

That is, the lifting base 30 is rotated by an upwind blowing to the base 32 while the lifting base 32 is flapping, and at this time, free rotation by the bearing 21 is possible.

The injection fan 40 is provided at a lower portion of the base portion 10 and injects air into the air passage portion 31 formed inside the lifting base 30.

At this time, the injection fan 40 may further include a connection pipe so that air can be directly supplied to the first through hole of the lower plate.

4 and 5, the lifting platform 30 is formed with a discharge portion that penetrates the upper outer side surface and discharges the air introduced into the air passage portion 31 to the outside.

A plurality of first exhaust holes 34 and a plurality of second exhaust holes 35 are formed on the left and right sides of the base 32 so that air is discharged toward the side of the base 32, The third exhaust hole 36 is formed at a position lower than the lower end of the exhaust gas outlet 32 so that air is discharged toward the lower end of the exhaust gas outlet 32. [

Here, the first discharge hole 34 and the second discharge hole 35 may be formed in a plurality of vertically arranged and larger diameters as they descend from the upper part to the lower part.

The third discharge hole 36 may be formed larger than the diameter formed at the bottom of the first discharge hole 34 and the second discharge hole 35.

That is, the air introduced into the air passage portion 31 is discharged to the first discharge hole 34, the second discharge hole 35 and the third discharge hole 36, so that the fan 32 can be flapped.

Particularly, since air is discharged from both sides of the base 32 through the first discharge hole 34 and the second discharge hole 35 toward the side, it can be flapped without being deflected in any one direction.

As the air is discharged toward the lower end of the base 32 through the third discharge hole 36, the flaps can be dynamically further directed.

The first exhaust hole 34, the second exhaust hole 35 and the third exhaust hole 36 extend from one side to the other side of the base 32 facing the platform 30, When the air is divided into three by the third zone, the air is formed so that the air can be discharged to the third zone. That is, the first discharge hole 34, the second discharge hole 35, and the third discharge hole 36 discharge the wind in the diagonal direction toward the third area.

At this time, as the wind is discharged only to the third zone of the unit 32, the third zone is exerted by the wind in the outward direction, and is expanded and fluttered at the same time. Also, the first zone and the second zone are unfolded as the third zone is exerted in the outward direction.

That is, the first section and the second section are tightened, and the machine 32 can be flashed only in the third section, so that the machine 32 can be easily identified as a whole.

The third exhaust hole 36 is formed at a lower position than the lower end of the base 32 and is discharged upward toward the third region of the lower end of the base 32 to prevent the base 32 from sinking This can be done. The first discharge hole 34 and the second discharge hole 35 also have a large amount of wind to be discharged from the upper part to the lower part and the wind 32 is discharged upward toward the third area, Do not sit down and stay tighter, and the third zone may be fluttering.

6 and 7, the gear lift apparatus according to the present invention further includes a blocking wall 50 and a connecting portion 60. [

The blocking wall 50 is provided in the air passage portion 31 of the lifting base 30 and is rotated integrally with the lifting base 30. At this time, the blocking wall 50 is provided so as to be positioned lower than the formation position of the discharge portion, that is, lower than the third discharge hole 36. But it is not limited thereto. In other words, in the middle or upper portion of the air passage portion 31, since the space to be filled with the air supplied from the injection fan 40 becomes large, As shown in FIG.

In addition, the lower end of the lifting platform 30 is formed to be spaced apart from the upper side of the lower plate 11, and is formed lower than the upper side of the upper plate 13.

Therefore, the lower end of the lifting base 30 is positioned below the upper side of the upper plate 13, and the blocking wall 50 is provided at the lower end of the lifting base 30, The space can be minimized and can be discharged directly to the discharge portion through the connecting portion 60 to be described later. Thus, when the injection fan 40 is operated, the air can be discharged to the discharge portion in a short period of time to flap the base 32.

The blocking wall 50 is formed with a communication hole 51 corresponding to the discharge portion.

The connection portion 60 connects the discharge portion and the communication hole 51 so as to move the air introduced into the air passage portion 31 to the discharge portion at a high pressure.

Further, the base elevating apparatus according to the present invention further includes a first light emitting portion 71, a second light emitting portion 72, an illuminance sensor 74, a control portion, and an on-off valve.

The first light emitting portion 71 is provided outside the lifting base 30 and is provided between the first discharge hole 34 and the second discharge hole 35 to emit light toward the base 32.

At this time, the first light emitting portion 71 is provided in three to five, and is provided vertically and horizontally to the base 32. [

The ferrule 73 is provided on the upper portion of the lifting base 30 and is made of a material through which light is transmitted.

The second light emitting portion 72 is provided inside the end piece 73 to emit light.

Thus, the light emitted from the second light emitting portion 72 is transmitted through the rod 73.

The illuminance sensor 74 is provided on the lifting base 30.

The control unit turns on the first light emitting unit 71 and the second light emitting unit 72 according to the illuminance sensed by the illuminance sensor 74.

On the other hand, the first light emitting unit, the second light emitting unit, the illuminance sensor, the wind speed sensor, and the like installed on the hoist are connected to the control unit through wires. At this time, since the hoisting frame rotates, it can be connected by a slip ring structure to prevent twisting of the wire.

At this time, the slip ring is provided through the lower plate 11.

The opening / closing valve is provided in the first exhaust hole 34 and the second exhaust hole 35. The open / close valve may open / close the first discharge hole 34 and the second discharge hole 35 and may be a solenoid valve, but is not limited thereto.

The control unit controls the open / close valve to open / close the first discharge hole (34) and the second discharge hole (35).

That is, the control unit repeatedly opens and closes the first discharge hole 34 at the first predetermined time, and the second discharge hole 35 repeats closing and opening. In other words, the control unit opens the first exhaust hole 34 and closes the second exhaust hole 35, closes the first exhaust hole 34 after the first set time, 35 are opened.

As described above, the control unit reverses the opening and closing of the first exhaust hole 34 and the second exhaust hole 35, so that the fan 32 can flutter more vigorously forward and backward by the wind blown alternately back and forth .

The sound absorbing material is provided on the inner wall of the air passage portion 31 of the lifting base 30 so as to absorb the noise generated by the inflow and outflow of air.

Particularly, it is preferable that the hoist frame 30 having a hollow shape absorbs the sound amplified by the sound absorbing material as the noise generated from the injection fan 40 is transmitted and amplified.

Further, the gear lifting device according to the present invention further includes a gear portion, a driving portion, and a communication module.

The gear portion includes a first gear, a second gear, and a gear shaft.

The first gear is provided in the lower part of the inside of the take-

The second gear is provided on the lower portion of the base portion 10, that is, the housing.

The gear shaft connects the first gear and the second gear.

The driving portion is engaged with the second gear.

That is, when the driving portion is operated, the second gear rotates, and the rotational force is transmitted to the gear shaft to be transmitted to the first gear. Thus, the rotational force transmitted to the first gear can rotate the lifting base 30.

At this time, when the wind speed sensor detects a wind velocity lower than a predetermined wind speed, the controller turns on the injection fan 40 to make the fan 32 flutter, and turns on the drive unit, During the set time, the platform 30 is rotated and stopped in one direction. That is, the control unit repeats the rotation and stop of the lifting base 30 to the driving unit. In addition, the control unit turns off the injection fan 40 and the driving unit when the wind speed is higher than a predetermined wind speed.

Accordingly, the control unit can control the driving unit to rotate the lifting base 30 and control the injection fan 40 so as to flap the base 32 even when the wind is not blowing.

The communication module is provided in the lifting base (30) and transmits / receives a control signal.

That is, the control unit transmits a control signal to a communication module provided in the base unit 30 located at a predetermined radius around any one base unit 30 to control the base unit 30 located at a certain radius have.

In other words, when the manager operates one of the lift platforms 30, the control signal corresponding to the operation is transmitted to the lift platform 30 located at a predetermined radius by one of the control platforms of the lift platform 30, (30) is controlled in accordance with a control signal received from any one of the elevation (30) communication modules. Accordingly, the manager can control not only one of the lift platforms 30 within a certain radius but also smooth operation and management, without needing to control the lift platform 30 every day.

Meanwhile, a solar cell for converting sunlight into electric energy may be provided on the upper part of the platform 30. The power generated by the solar cell can be charged, and power can be supplied to the first light emitting unit 71 and the second light emitting unit 72 at night.
