Description

[0001] The present invention relates to an extending type lotus lamp lifting device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extendable lifting lifting device, and more particularly, to an extendable lifting lifting device that can easily expand and contract a region where a lifting lamp is installed and minimizes installation restrictions on ceiling size and shape.

It is well known that Buddhist ceremonies, such as Buddhist ceremonies, such as Buddha's birthday, are designed to celebrate the birth of the Buddha.

These religious events not only maximize Buddhist power of Buddhist believers, but also protects them from various evils and diseases, and provides relief of mind and body, promoting liberation and peace from defilement, promoting the enjoyment of wealthy movies, It is a traditional wind speed that can meet the expectation of

On the other hand, the lantern is installed not only in the grounds such as a roadside or a temple, but also in a ceiling of a hall.

In order to install the lamps on the ceiling of the above-mentioned hall, the worker hangs the lamps on the ceiling by using a ladder or the like.

However, such installation work has been problematic in that the efficiency is low, such as that the convenience of the work is poor and the work time is excessive.

In addition, a series of work for installing the lantern on the ceiling has a problem that the work is very inconvenient due to an overhead posture and further, it can cause musculoskeletal diseases of the worker.

In order to solve such a problem, there has been recently provided a so-called lifting lifting device "Korea Registration No. 10-1416795", in which a separate frame is provided and a frame is mounted on the frame and the frame is lifted and lowered using a driving portion.

With this type of lifting lifting device, it is possible to provide a convenient and easy longevity installation work by disposing the frame on the ground, installing the lanterns at uniform intervals in the frame, and raising the frame on the ceiling.

However, the conventional lifting lifting device has the following problems.

First, since the size of the frame is fixed, it is difficult to efficiently cope with the ceiling size.

That is, when the size of the manufactured frame is reduced or the size of the frame is enlarged in order to match the size of the ceiling of the leg, it is very troublesome to use the fire work such as cutting and welding, There was a possibility of a safety accident.

Second, the frame is interfered with the structure installed in the ceiling of the main hall, so that there is a problem that additional work such as a structure change and removal operation is required.

For example, when a lamp is installed on a ceiling of a ceiling, since the frame is interfered with the lamp during the process of raising the frame to the ceiling, it is difficult to install the frame installed with the ceiling light.

This not only inconveniences the operation of separating the lamp, but also causes another problem such as a lighting member since the lamp is removed.

Third, there is a problem that it is difficult to maximize the balance of the frame suspended from the wire.

That is, since the wire is coupled only to the edge of the frame, flow of the frame may occur, and the frame may be shaken even in a slight vibration, so that the stability is not provided.

Of course, a wire installation structure for supporting several points of a frame is disclosed in the prior art " horizontal level holding type lifting device ", " Patent No. 10-1267471 ", but this structure also has a structure capable of supporting the center of the frame There is a problem that it is difficult to maximize the frame balance.

Further, since the adjustment of the tension of the wire is performed by the turnbuckle provided on each of the wires, there is a problem that workability is poor.

Hereinafter, an extended type lifting apparatus according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4B.

The extendable lifting lifting device has a technical feature that allows the frame to be installed with the lanterns to be easily extended and retracted, and to support the center of the frame.

Accordingly, it is possible to minimize the size and shape of the structure for installing the ceiling or the frame and the restriction on the installation of the frame according to the interference, thereby maximizing the maintenance of the frame balance.

The extended lifting lifting device for this purpose includes a driving unit 100, a main wire 200, a main frame 300, an extensible frame 400, a detachable unit 500, a folding unit 600, (700).

The driving unit 100 generates power for moving up and down the main frame 300 and the extensible frame 400 and includes a motor 110, a drum 120, and a shaft 130.

The drum 120 winds the main wire 200 and is rotated forward and backward by the power of the motor 110.

The drum 120 is provided in plural and corresponds to the number of the main frame 300 and the stretching frame 400. [

The shaft 130 is axially coupled to the motor 110, and the plurality of drums 120 are axially coupled.

That is, the plurality of drums 120 are axially coupled in the longitudinal direction of the shaft 130, and the main wire 300 and the stretching frame 130 are rotated while the main wire 200 is wound or unwound by forward and reverse rotation of the shaft 130, (400).

On the other hand, a guide roller 140 is provided.

The guide roller 140 serves to guide the main wire 200 wound around the drum 120 to the main frame 300 and each of the extensible frames 400 and a fixed anchor 150 After the installation, the guide roller 140 is installed on the fixed anchor 150.

At this time, the guide roller 140 is positioned at the upper center of the main frame 300 and each of the extensible frames 400.

The mounting position of the driving unit 100 is not limited.

Next, the main wire 200 functions to raise and lower the main frame 300 while being unwound from the drum 120 rotated by the power of the motor 110 or wound around the drum.

The lower end of the main wire 200 is connected to a screw thread described later.

Next, the main frame 300 is lifted and lowered by the power of the driving unit 100 to constitute a frame in which a lantern is installed.

The main frame 300 preferably has a rectangular frame, and is preferably formed in a lattice shape.

A fixing member 301 for fixing the sub wire 310 is provided at each corner of the main frame 300.

The sub wire 310 supports the main frame 300 and is connected between a fixing member 301 provided at each corner of the main frame 300 and a tension adjusting means 700 described later.

That is, the main wire 200 is a power transmission means for moving up and down the main frame 300. The sub wire 310 plays a role of maintaining the balance of the main frame 300 together with the tension adjusting means 700 .

Next, the extensible frame 400 is detached around the main frame 300 or detached from the extensible frames 400 to stretch the entire frame.

That is, since the shape and size of the ceiling or the structure for installing the lantern may be different from each other, the stretching frame 400 may have a structure in which the size and shape of the frames 300 and 400 are corresponded to different ceilings or structures, To be less constrained.

The extensible frame 400 may also be formed to correspond to the shape of the main frame 300 and need not be formed in the same manner as the main frame 300.

That is, as shown in FIG. 2, by not making the width of the extensible frame 400 uniform, it is possible to more finely correspond the frames 300 and 400 to the ceiling or the structure size.

The detachment means 500 preferably detaches between the main frame 300 and the extensible frame 400 and between the extensible frames 400 and is installed at the periphery of each of the frames 300 and 400.

The structure of the detachable unit 500 is not limited and it may be configured to be detachable between the frames 300 and 400.

In the present specification, as shown in FIG. 1, the detachment means 500 will be described with reference to an example in which a pipe that can be fitted to the periphery of each of the frames 300 and 400 is installed.

The detachment means 500 is provided at a periphery of the frames 300 and 400 as a plurality of pipes as described above. The pipe is composed of a female pipe 510 and a male pipe 520.

The arm pipe 510 and the male pipe 520 are both protruded from the periphery of the frames 300 and 400 and are formed in a hollow shape.

At this time, the inner diameter of the female pipe 510 is formed larger than the outer diameter of the male pipe 520.

As a result, the male pipe 520 can be fitted into the inside of the arm pipe 510, thereby facilitating the detachment between the frames 300 and 400.

On the other hand, both the female pipe 510 and the male pipe 520 are formed with fixing holes H on their outer circumferential surfaces.

The fixing hole H is a structure for binding the bolts B to each other when the male pipe 520 is coupled to the arm pipe 510.

The fixing hole H and the bolt B may be formed by mounting the male pipe 520 in the arm pipe 510 only by inserting the male pipe 520 into the frame 300,400 to prevent the falling of the frame 300,400.

The positions of the fixing holes H are all the same and preferably form a thread for screw connection.

The folding unit 600 is installed to be pivotable on the frames 300 and 400 so as to avoid interference between the frames or the interferences of the structures and the frames 300 and 400 with the frames installed thereon, .

The folding unit 600 is preferably installed on both the main frame 300 and the extensible frame 400 and is installed such that a part of the frames 300 and 400 is rotated by a hinge as shown in FIGS.

That is, the folding unit 600 may be configured such that a part of the frames 300 and 400 is rotatable up and down, and when an interference, for example, a lamp is installed in the ceiling or the structure, 600 so as to avoid interference between the lamp and the frames 300, 400.

Thus, when the frames 300 and 400 are installed on the ceiling or the structure, unnecessary problems such as the need to remove the electric lamps are avoided in order to avoid interference between the frames 300 and 400 and the electric lamp.

At this time, although not shown, the folding unit 600 may be installed so as to be rotated not only upward but also downward.

That is, the folding unit 600 may be configured to be pivoted downward by providing the hinge at the bottom of the frames 300 and 400 rather than the top.

Meanwhile, the frames 300 and 400 are provided with restricting means 610 for restricting the folding of the folding unit 600.

That is, the folding unit 600 should be restrained so as not to be rotated upward or downward at normal times. For this purpose, the restraining unit 610 is provided at a portion corresponding to the end of the folding unit 600 By forming the step 610, the folding unit 600 is prevented from falling down.

Although it is not shown, when the folding unit 600 is installed to rotate downward, it is understood that the restraining unit 610 must be provided at the end of the folding unit 600 and at the bottom of the frames 300 and 400.

The restraining means (not shown) provided on the bottoms of the frames 300 and 400 may be configured so that the folding unit 600 does not fall downward, and may be provided, for example, with a latch and a ring.

Next, the tension adjusting means 700 is configured to increase the balance of the main frame 300, that is, the horizontal holding force, and is installed at the center of the main frame 300

The plurality of subwires 310 can maintain the balance of the main frame 300. However, if the plurality of subwires 310 are not uniform in tension and support the center of the main frame 300, The tension adjusting means 700 can maintain the tension of the sub wire 310 evenly and support the center of the main frame 300 to maximize the horizontal retention force of the main frame 300 I would like to.

The tension adjusting means 700 includes a screw rod 710, a lifting bracket 720, and a nut 730 as shown in FIG.

The screw rod 710 supports the center of the main frame 300 and is connected to the main wire 200.

The threaded rod 710 is installed upward from the center of the main frame 300 and a ring for coupling with the main wire 200 is formed at the upper end of the threaded rod 710.

A thread is formed on the outer peripheral surface of the threaded rod 710.

The lifting bracket 720 moves up and down along the screw rod 710 to adjust the tension of the sub wire 310.

A through hole 721 is formed at each corner of the lifting bracket 720 for connection with the sub wire 310. The lifting bracket 720 has a through hole corresponding to the diameter of the screw rod 710.

The nut 730 restrains the position of the lifting bracket 720 on the screw rod 710 and is located on the upper surface and the lower surface of the lifting bracket 720.

With this configuration, the nut 730 can be rotated on the screw rod 710 to move the lifting bracket 720 up and down.

Hereinafter, the installation and operation of the extended lifting lifting device having the above-described configuration will be described.

And the driving unit 100 is installed on one side of the ceiling.

At this time, the shaft 130 axially coupled to the motor 110 is disposed across the ceiling or the structure, and the drum 130 is provided with a plurality of drums 120 in the longitudinal direction of the shaft 130.

The main wire 200 is wound on the drum 120 and the main wire 200 is guided by the guide roller 140 as shown in Figure 1 to be installed on the main frame 300 and the respective stretching frames 400 And is connected to the screw rod 710.

When the driver 100 is installed, the nut 730 is rotated to lift the lifting bracket 720 on the screw rod 710 as shown in FIGS. 4A and 4B.

At this time, as the lifting bracket 720 is lifted, the sub wire 310 is pulled, so that all of the sub wires 310 that have been loosened are in a tight state.

That is, since the tension of the plurality of subwires 310 supporting the corners of the main frame 300 can be uniformed at the same time by only one lifting bracket 720, the convenience of work can be improved.

Particularly, since a screw rod 710 is formed at the center of the main frame 300 and the sub wires 310 support the corners of the main frame 300 around the screw rod 710, The horizontal level of the display unit 300 can be maintained more stably and continuously.

Then, the total size of the frames 300 and 400 is determined in consideration of the shape and size of the ceiling or the structure of the room where the lantern is to be installed.

The male pipe 520 or the arm pipe 510 formed at the periphery of the extensible frame 400 is coupled to the arm pipe 510 or the male pipe 520 formed at the periphery of the main frame 300.

The bolts B are screwed through the fixing holes H for strengthening the coupling force between the male pipe 520 and the arm pipe 510 so that the coupling force between the frames 300 and 400 can be further strengthened.

In addition, a stretch frame 400 considering the ceiling or the size of the structure is further attached to the periphery of the extensible frame 400 provided on the periphery of the main frame 300.

At this time, a series of processes to be coupled between the extensible frames 400 is the same as the above-described process.

Thus, the layout of the entire frame 300 and 400 is determined as shown in Fig.

Then, the tension of the sub wire 310 of the elastic frame 400 coupled to the main frame 300 is also uniformly adjusted.

The series of processes for adjusting the tension of the sub wire 310 is the same as the tension control of the sub wire 310 installed on the main frame 300.

Next, the folding unit 600 provided on the main frame 300 and the extensible frame 400 is rotated in consideration of interferences installed in the ceiling or the structure.

At this time, due to the pivoting folding unit 600, the main frame 300 and a part of the extensible frame 400 are opened to provide a space through which the interference of the ceiling or the structure is passed.

Next, the main frame 300 and the extensible frame 400 are suspended by wires or wires.

The main wire 200 is wound around the drum 120 to lift the screw rod 710 installed in each of the frames 300 and 400. The drum 120 is rotated in the normal direction by operating the driving unit 100. [

At this time, the main frame 300 provided with the screw rod 710 is also lifted, and the extensible frame 400 coupled to the main frame 300 is raised.

At this time, since the sub wires 310 are supported at the corners of the frames 300 and 400 based on the screw rod 710 installed at the center of each of the frames 300 and 400, the frames 300 and 400 can be raised in a stable manner.

At this time, as the interference such as a lamp installed in the ceiling or the structure passes through the open part through the rotation of the folding part 600, no interference occurs between the frames 300 and 400 and the structure, So that it can be smoothly placed in the ceiling or the structure.

As a result, the installation of the lantern is completed on the ceiling of the ceiling or the structure installed on one side of the ceiling.

Hereinafter, the operation of the extended lifting lifting device having such a structure will be briefly described.

When the motor 110 of the driving unit 100 operates to rotate the drum 120 in the forward direction, the lifting wire 820 is wound on the drum 120 to lift the frame bracket 800.

At this time, since both of the lifting wires 820 are guided along the rotating roller 811, the frame 300 is smoothly lifted.

At this time, the extensible linker 830 is contracted while the ends of the unit linker are rotated with respect to each other, so that the synergistic action of the frame 300 is made flexible.

Conversely, to lower the frame 300, the motor 110 is operated to rotate the drum 120 in the reverse direction.

At this time, the lifting wire 820 wound on the drum 120 is released and the frame 300 is lowered by its own weight.

One end of this telescopic linker 830 is also mounted on the frame bracket 800 and the other end thereof is mounted on the structure bracket 810.

The telescopic linkers 830 are axially coupled to each other at points where they intersect with each other, so that the telescopic linkers 830 can be flexibly stretched to flex the lifting and lowering of the frame 300 by the lifting wires 820.

At this time, the frame bracket 800 and the structure bracket 810 provided at one end and the other end of the telescopic linker 830 may be formed with grooves G so that the telescopic linker 830 can be smoothly expanded and contracted have.

9 and 11, the grooves G are formed on both sides of the structure bracket 810 and on both sides of the frame bracket 800, respectively, with the rotation roller 811 as a center.

That is, the groove G is a structure for providing a space in which both ends of the telescopic linker 830 can be moved in the process of expanding and contracting the telescopic linker 830.

The third embodiment of this type of lifting lifting apparatus further comprises a telescopic linker 830 so as to smoothly guide the lifting and lowering of the frame 300 as well as lifting the wire lifting wire 820 from the drum 120 rapidly The frame 300 is supported by the telescopic linker 830, so that the frame 300 does not fall down to the ground.

Accordingly, it is possible to prevent human accidents due to equipment breakage and frame fall.

12 to 15, a drop limiting wire 900 may be further provided between the frame bracket 800 and the structure bracket 810.

The drop limiting wire 900 is a structure for smoothly operating the telescopic linker 830 in the process of bringing the frame back into place after the frame falls due to a malfunction or malfunction of the driving unit 100.

That is, when the frame 300 is dropped due to a failure or malfunction of the driving unit 100, the stretch linker 830 is completely unfolded by the load of the frame 300 to be almost linear, It may happen that the telescopic linker 830 can not be smoothly contracted in the process of lifting the frame 300 to the original position. The falling limit wire 900 restricts the maximum distance that the telescopic linker 830 is extended .

12 to 15, the stretch linker 830 is not completely opened. Therefore, after the driver 100 is repaired, the frame 300 is rotated The operation of the telescopic linker 830 can be smoothly performed in the process of repositioning.

At this time, the dual type stretch linker 830 may be provided in various configurations as shown in FIGS.

Fig. 13 shows a configuration in which the telescopic linker 830 is provided without the configuration of the grooves G, and Figs. 14 and 15 show a configuration in which the telescopic linker 830 is provided with a connection node 831. Fig.

As the connecting rod 831 is further provided on the telescopic linker 830, the telescopic operation of the telescopic linker 830 can be performed more smoothly.

At this time, the connection node 831 may be hinged to expose the end of the unit linker as shown in FIG. 14, or may be hinged so that the end of the unit linker is not exposed as shown in FIG.

The lifting wire 820 may control lifting and descending of the main frame 300 at the center and the telescopic linker 830 may be installed at each corner of the frame 300.

At this time, the frame bracket 800 and the structure bracket 810 may be provided in plural, respectively, or may be formed to correspond to the length of the frame 300, or may be mixed and applied as shown in FIG.

The telescopic linker 830 is connected between the frame bracket 800 and the structure bracket 810 and is provided at a plurality of corners of the frame 300.

This is to effectively support the load of the frame 300.

A central bracket 910 is installed at the center of the ceiling or structure above the frame 300.

The center bracket 910 includes a rotating roller 811 and guides the lifting wire 820 to the center of the frame 300.

That is, the lifting wire 820 wound on the driving unit 100 is fixed to the center of the lower frame 300 through the rotating roller 811 of the center bracket 910.

The lifting wire 820 is lifted or lowered by the operation of the driving unit 100 so that the frame 300 is lifted and lowered. In this process, the telescopic linker 830 of each corner of the frame 300, Thereby efficiently guiding the frame 300 up and down.

On the other hand, the extended type lifting apparatus including the above-described telescopic linker 830 has a technical feature that the ceiling or frame is not greatly restricted by the form of the structure in which the frame 300 is lifted and lowered.
