Description

Lighting lift Apparatus}

The present invention relates to a light lifting device, and more particularly to a light lifting device used to provide optimal lighting and safe maintenance in the gymnasium or various indoor meeting places.

As is well known, it is necessary to adjust the height of lighting according to the situation in various indoor meeting places such as gymnasium or auditorium with high ceiling height, so that the optimal lighting can be provided. It is necessary to lift the lamp in order to.

In order to satisfy such a request, Korean Patent Laid-Open Publication No. 1999-0046570 (name of the invention: a lighting fixture auto-adjusting device and its adjusting method; hereinafter referred to as “quotation invention”) has been proposed.

According to this cited invention, it installs a primary roller 107 on the lamp support 109, and installs a secondary roller 108 in pairs on the ceiling, and the primary and secondary rollers 107, 108 may be extended or additionally installed depending on the length of the lamp support 109 and the number of lamps,

The wire 105 'passes through the upper roller of the secondary roller 108 of the ceiling, the wire 105' passing through the top roller of the last ceiling passes through the lower roller 108, and on the lamp support 109 The wire 105 is connected to the installed primary roller 107, and the wire 105 passes through the lower roller of the secondary roller 108, and then passes through the primary roller 107 connected to the lamp support 109. 105 ', the wire 105 on the opposite side is guided to the guide roller 104 and the wire 105' is guided to the guide roller 104 'and connected to the wire rotating drums 106 and 106'. The wire rotating drums 106 and 106 'are connected to the secondary gear, and the secondary and tertiary gears are engaged with both ends of the primary gear, and the upper and lower controllers are connected to the primary and third gears as necessary. Lighting fixture support automatic control device to use

When the up and down controller 101, which can be operated manually or by electric or remote control, rotates, the wire rotation drums 106 and 106 'connected to the primary and secondary gears or the third gear rotate, and the wire rotation drum 106, Wires 105, 105 'connected to the guide rollers 104, 104' are guided and unwound or unwound, allowing the lamp support 109 to move up and down while maintaining equilibrium, and up and down when the desired position is reached. The controller 101 is to be stopped.

Therefore, it is possible to elevate a plurality of lights at the same time, and in the process of elevating it can be conveniently controlled by manual or electric or remote control can be pursued for ease of use.

On the other hand, the cited invention uses a single row of ropes for raising or lowering a lamp, and thus, a plurality of lamps, ballasts, and a lamp support 109 are suspended in a single row of ropes 105 and 105 '. As the number of lamps and the length of the lamp support becomes longer, the load becomes enormous, and the stress concentration on one rope continues and the fatigue of the metal increases, resulting in a shortening of the life. It is not possible to exclude the fear of falling of the heavy object at a high position. In addition, there is a problem that the overall operation occurs even when an error occurs in only one of the rope and a plurality of rollers.

In addition, the position of the winding wound on the winding drum becomes irregular due to the vibration of the instruments inevitably generated during the operation, and thus a phenomenon in which the rope overlaps the winding position occurs. Therefore, the rise and fall speed unevenness is caused when the lamp support is raised or lowered, which causes a problem of vibration of the lamp support.

In view of the above-described conventional problems, an object of the present invention is to prevent an excessive load on one rope and to minimize the influence on the overall operation even when an error occurs in any one of the ropes and a plurality of rollers. The present invention provides a lamp lifting device that allows the lamp support to rise and fall in a quiet state.

In order to achieve this purpose, the present invention installs a winch in the center for winding up and down or unwinding a rope used for lifting up and down the lamp support assembly, and passes through a plurality of rollers to the left and right of the lamp supporter. It is proposed a lifting device for lifting and lowering a plurality of ropes by winding or unwinding a plurality of ropes to be raised and lowered.

In addition, the present invention proposes a lamp lifting device provided with a guide plate so that the rope is not wound around the winding drum of the winch.

Accordingly, the present invention is a state in which stress is distributed to a plurality of ropes in lifting and lifting a heavy-weight lamp support assembly, which reduces the fatigue of metal tissues, thereby prolonging its life and enabling safe use, even in case of component failure. The overall operation is to be possible, there is an effect that can be raised and lowered in a quiet state by greatly reducing vibration during the lifting of the lamp support assembly.

This invention is described in more detail with reference to the accompanying drawings as follows.

The overall structure of the present invention is shown in FIG.

As can be seen from this, the present invention provides a plurality of winding drums 4 which are rotated forward and backward by the power of the motor 2 and the speed reducer 3 installed between the frame 1 and the frame 1 in the ceiling. , A winch 7 composed of a guide roller 3 for guiding the introduction into the winding drum 4, a fixed roller 5 installed at regular intervals on the frame 1, and a length selected according to the size of the indoor space. Lamp support 11, lifting roller 6 fixed above the lamp support 11 at a position corresponding to the fixing roller 5, and one rope 9 for each group divided into parts. ) Is allocated so that one end is fixed above the lamp support 11 and the other end is composed of a plurality of ropes 9 wound around the winding drum 4 of the winch 7.

The present invention, first, as the lamp support 11 is lowered as shown in FIG. 2, so that the lamp 8 is lowered to the eye level of the worker standing on the floor of the room. You will be doing some maintenance.

In this way, power is supplied to the motor 2 of the winch 7 so that the winding drum 4 of the winch 7 winds up the rope 9. 4) will be wound.

That is, in the present invention, as shown in Figs. 3 and 4, the reduction gear 3 rotates by the rotation of the motor 2, and the rotation shaft of the winding drum 4 is connected to the rotation shaft of the reduction gear 3, Since the rotating shaft of the other winding drum 4 is interlocked by the gear, the two winding drums 4 rotate in the same speed opposite directions. Accordingly, as shown in FIG. 2, the two ropes 9 on both sides are simultaneously wound at the same speed, and the lamp support 11 is able to ascend horizontally. In this way, when the lamp support 11 is raised to a certain height, the operator cuts off the power supplied to the motor 2 or the motor 2 by a separate sensor (not shown). By interrupting the power supply to stop the rise of the lamp support (11).

In this state, the power is applied to the wires connected to the plurality of lamps 8 to be turned on or to be turned off.

In this state, if the height of the lamp 8 should be lowered or lowered to the lower limit height for repair of the lamp 8, the power should be applied to the motor 2, but the polarity is reversed. The motor 2 rotates so that the winding drum 4 of the winch 7 rotates in the opposite direction as before. As a result, the rope 9 wound around the winding drum 4 is released, and thus is lowered by the load of the lamp support 11. When a predetermined time passes in such a state, the lamp support 11 descends to a desired position. At this time, when the power supplied to the motor 2 is cut off, the rotation of the reducer 3 is stopped, and thus the winding drum ( The rotation of 4) stops and the current falling position is maintained. Therefore, it is possible to work such as replacing or repairing the lamp (8) or ballast by lowering to the eye level of the operator to the illumination at the desired height.

By repeating this process, the present invention is to be able to use conveniently by positioning the lamp support 11 in the desired position, and maintenance, repair can be carried out very safely. In addition, in this process, the winding 9 is wound around the winding drum 4 of the winch 7 and the process of unwinding is repeated. In practice, the position where the rope 9 is wound on the winding drum 4 may be different each time due to the vibration of various instruments in the process of winding the rope 9 on the winding drum 4, in which case the rope A phenomenon in which the rope 9 is repeatedly wound on (9) may occur. Such a phenomenon may cause irregularities in the ascending and descending speeds of the lamp support 11 by making the speed at which the rope 9 winds up irregularly. Therefore, in the present invention, as shown in FIG. 4, the winding 9 wound on the winding drum 4 by pressing the rope 9 by the guide plate 10 having elasticity is detected by the winding drum 4. In order to be wound in order, it is possible to eliminate the unevenness of the winding speed and the unwinding speed of the rope (9) due to the winding position unevenness of the rope (9).

In this way, since the present invention uses a plurality of ropes 9 in elevating the lamp support 11, stress is concentrated on the plurality of ropes 9, which greatly reduces the metal fatigue. Therefore, it can be used safely, and unlike the case of operating by only one rope, there is an advantage that stable operation is performed by a plurality of ropes 9, and the rope 9 is wound in a desired state, and the lamp is released as it is released. As the elevating of the earth 11 is made, there is an effect of being able to ascend and rise in a quiet state.
