Description

Device for Lifting up and down Objects}

The present invention relates to a device for lifting an object such as various kinds of screens or exhibits or stage decorations. More specifically, the present invention uses a gear drum equipped with a strip instead of a wire rope to reduce the space required for the installation and to easily adjust the installation position while lifting various objects. It is about.

In general, the conventional lifting device 10 used in the stage is, as shown in Figure 8, the hanging rack 16 to suspend the sculpture for the stage background, and a wire rope connected to the wire rack (Wire Rope, 11) ), A pulley (Pulley) 12 for changing the direction of the rope, and a driving unit 15 for winding the rope. The stage device includes a driving unit 15 mounted on a grid frame 13, and ropes 11 are connected to a drum of the driving unit 15. For this reason, the hoisting device occupies a relatively large space (S) when installed on the ceiling (1) above the frame (13), in particular a force is applied from the rope (11) to the drive (15) side, i. Due to the power of the drive unit 15 is inevitably increased. In addition, since the sculpture hanger 16 is always lifted in a state where it is kept horizontal, there is a disadvantage in that it is not possible to cope at all when the object needs to be lifted slightly inclined.

Therefore, the present invention, unlike the conventional hoisting device described above, is provided with a gear drum equipped with a strip instead of a wire rope, so that the required installation space is small and the position can be easily adjusted during installation, and at the same time, it is possible to precisely adjust the elevation of the object.

Hereinafter, the lifting device of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5 are examples of the lifting device of the present invention, in which FIG. 1 is a front view, and FIGS. 2 to 5 are detailed views of respective parts of the device.

As shown in FIG. 1, the elevating device 100 according to the present invention includes a strip 110, a gear drum 120, a rotation shaft 130, a bearing bracket 140, and a driving unit 150. It is composed.

Unlike the conventional wire rope, the elevating device 100 of the present invention may use a thin strip so that the installation space may be greatly reduced. That is, in the case of the wire rope, the width of the drum is increased because it is wound in the transverse direction along the axis of the drum, while in the case of the strip, the width of the drum can be greatly reduced because it can be wound in the longitudinal direction along the radial direction of the drum. The strip may be made of steel, alloy, or the like, and it is usually preferable to use one having a strength equal to or higher than that of the wire rope.

2 is a detailed view of the strip, which is equipped with a hook 114 to suspend various types of objects at one end. If necessary, as shown in FIG. 3, between the strip and the hook 114, a holder 118 having a flange 116 formed at a lower portion thereof is mounted, and the flange 116 of the holder 118 is mounted. By inserting the sliding (Sliding) in the groove 162 of the hanging rack 160, the hanging rack 160 can be suspended. Of course, the shape of the holder 118 and the flange 116 may be various, it is sufficient that the structure is inserted into the groove 162 of the holder hanger 160 so as not to fall out of the holder hanger downward. The sculpture rack 160 is suitable for carrying the stage equipment for the stage lighting or various backgrounds, or for the creations for various exhibitions.

In addition, since the strip 110 has a scale mark 112 on the surface, the object can be lifted by a certain stroke, so that the position of the object to be lifted can be accurately controlled. This strip is wound on or released from the gear drum 120.

4 shows an exploded perspective view of the gear drum 120. The drum in the elevating device 100 is a gear drum 120 coupled to the gear. In detail, the gear drum 120 may include a main drum 122, an auxiliary drum 121, and a side plate 129.

The main drum 122 has a gear 126 formed on an inner circumferential surface thereof, and flanges 124 and 124 'are formed on both sides thereof. In addition, the auxiliary drum 121 has a gear 125 formed on a portion of the outer circumferential surface thereof to be engaged with the gear 126 of the inner circumferential surface of the main drum. In addition, a flange 127 is formed at one side of the gear 125 of the auxiliary drum 121, and a thread line 121c is formed at the other side, and a protrusion 121a is provided inside the inner through hole 123b. The inner protrusion 121a of the inner through hole 123b is inserted into the groove 132 of the rotation shaft 130, and in this state, the gear drum 120 is axially coupled to the rotation shaft 130 by the screw 128. . In addition, the side plate 129 has a screw thread formed in the inner through-hole 128a, and thus the side plate 129 is screwed to the auxiliary drum so that the main drum 122 does not fall out.

The gear drum 120 is axially coupled to the rotary shaft 130 to wind or unwind the strip 110 in accordance with the rotation of the rotary shaft. At this time, the gear drum 120 of the present invention can be set to a different length of the strip, as will be described later (see Figure 7). That is, when the main drums 122, 122, 122 are mounted on the auxiliary drums 121, 121, 121 in each of the gear drums 120, 120, 120, the main drums are rotated by different amounts, By adjusting the lengths of the strips 110, 110 and 110, the object can be lifted in an inclined state.

The rotation shaft 130 is axially coupled with the gear drum 120 to rotate the gear drum 120 in accordance with the rotation of the drive unit 150. Since the groove 132 is formed in the rotary shaft 130, the interval of the gear drum 120 axially coupled to the rotary shaft can be arbitrarily adjusted along the longitudinal direction of the rotary shaft.

5 is an exploded perspective view of a bearing bracket 140 for supporting the rotating shaft 130. As shown in FIG. 5, the rotation shaft 130 is bolted to the channel 143 mounted on the ceiling 1 by the support bars Bar 144 in the state of being inserted into the bearing bracket 140. ) And the nut 146 may be supported. Because of this, the lifting device of the present invention can arbitrarily adjust the position of the bearing bracket 140 along the longitudinal direction of the channel 143, it is possible to easily adjust the installation position of the lifting device 100 itself.

One end of the rotating shaft 130 is mounted with a driving unit 150 to drive the rotating shaft 130. In the present invention, the driving unit 150 may be a conventional motor having a brake and a deceleration function, and for example, a straight motor is preferable. As shown in FIG. 1, the driving unit 150 enables the elevating device 100 to be installed even in a narrow space S of the ceiling 1.

On the other hand, Figure 6 shows a plan view of another lifting device of the object according to the present invention. The lifting device 200 of FIG. 6 has a basic mechanism similar to that of the lifting device 100 of FIG. 1, but differs in that it can be safely lifted from all directions when lifting a three-dimensional object such as a stage sculpture. have. That is, the lifting device 200 of FIG. 6 includes a strip (not shown) having a hook mounted at one end, a gear drum 220 for winding or unwinding the strip, and a rotating shaft 230 axially coupled to the gear drum. The basic configuration includes a bearing bracket 240 supporting the ceiling 1 so that the rotating shaft is rotatable, a driving unit 250 for driving the rotating shaft 230, and the like. Same as 100). However, the rotating shaft 230 is composed of a plurality (6 in Figure 6), each of the rotating shaft 230 is rotated in conjunction with each other through the bevel gears 234 at both ends thereof. In addition, the driving unit 250 is installed in the middle of one of the rotating shafts 230, the rotating shaft 230 opposite to the rotating shaft 230 in which the driving unit 250 is installed is separated from each other.

Hereinafter, with reference to the accompanying drawings, the effect of the lifting device of the present invention will be described in detail.

As shown in FIG. 1, the elevating device 100 according to the present invention basically mounts the sculpture rack 160 on each strip 110 and then applies a power (not shown) to the driving unit 150. As the gear drum 120 rotates in accordance with the rotation of the rotary shaft 130, the strip hanger 160 may be elevated by lifting or winding the strip 110. In the conventional lifting device using a wire rope, the vertical force of the object is raised as well as the lateral force generated by the rope, so that a large load is applied to the driving unit. Elevation is possible.

In addition, since the strip 110 of the elevating device 100 has a graduation mark 112, it is possible to determine the exact stroke at the desired elevating position.

In addition to the basic operation described above, the elevating device 100 may elevate the object 164 in an inclined state, as shown in FIG. 7. That is, when it is necessary to install an object in an inclined state such as a stage background or the like, the main drums 121, 121, 121 of the main drums 121, 121, 121 are rotated with respect to the auxiliary drums 122, 122, 122 of the gear drum 120. The main drum is mounted on the auxiliary drum in a state in which the entire quantity (for example, one revolution or one pitch of the drum gear when the precision is required) is rotated differently. Accordingly, the strips 110a, 110b, and 110c are mounted to different lengths, and when the driving unit 150 is operated in this state, the object 164 may be lifted and inclined. Of course, even in this case, since the strip 110 of the elevating device 100 has a scale mark 112, it is possible to determine the exact stroke at the desired elevating position.

On the other hand, similar to the basic operation of the elevating device 100, the operation of the other elevating device 200 of FIG. In this case, the elevating device 200 can suspend a three-dimensional object in all directions, and all the rotating shafts 230 can be rotated at the same time through the bevel gear 234 by the operation of one driving unit 250, thereby stably three-dimensional. The object can be elevated by the correct stroke.

As described above, unlike the conventional lifting device, the lifting device of the present invention is provided with a gear drum equipped with a strip instead of a wire rope, so that the required installation space can be reduced, and the position can be easily adjusted during installation. You can adjust exactly where to climb.

In addition, unlike the conventional lifting device, the lifting device of the present invention can lift and lift a heavy object even with a drive unit having a less load by the vertical force of the strip than the lateral force by the wire rope, and can lift and lift the object in an inclined state.

Therefore, the elevating device of the present invention can precisely elevate various objects, such as various screens or exhibits, and stage equipment of large stage equipment, and can be very usefully applied in various fields.
