Description

  The present invention relates to a luminaire attachment / detachment device that can easily perform maintenance and inspection of a luminaire attached at a high place.

  Conventionally, maintenance and inspection of lighting fixtures installed indoors and outdoors, and replacement of lighting bulbs, for example, when exchanging lighting fixtures installed on utility poles or poles outdoors, You must climb the pole or pole directly, or work at a high place using a long ladder or an aerial work vehicle.

  The work at a high place is less stable than the ground, and the range of freedom of movement is limited, so that workability is deteriorated and there is a safety problem. Also, when using an aerial work platform, etc., safety may be ensured, but there are problems such as traffic obstruction due to road occupation and other use permits, and the cost of work becomes very high. There is.

  Similarly, for maintenance and inspection of lighting fixtures installed on indoor ceilings, etc., and replacement of lighting balls, it is also necessary to use steps and ladders when working at high altitudes. There is a problem that work in a poor place is inefficient and dangerous.

Therefore, in order to solve the above-mentioned problems, some lighting fixtures installed indoors and outdoors in high places are equipped with an elevator motor in the lighting fixture body, and the lifting and lowering structure has a structure for raising and lowering the lighting sphere with wires. Lighting devices have been proposed (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3).
There has also been proposed a telescopic fitting tube raising / lowering device capable of moving a lighting fixture from a high position to a low position by raising and lowering an illuminated telescopic fitting tube (see, for example, Patent Document 4). .)

First, as shown in FIG. 1, the pole head 31 of the attaching / detaching operation pole 3 is inserted below the bracket 2 to which the lamp 10 attached at a predetermined height position of the utility pole P is attached.
At this time, the inside of the bracket 2 is in a state where the instrument holder 4 is attached and locked as shown in FIG.

Thereafter, the operation button 33 of the attachment / detachment operation pole 3 is operated to raise the instrument lifting platform 5, and the instrument extraction pin 51 is fitted into the instrument extraction pin hole 44 of the instrument holder 4.
Next, when the attachment / detachment operation pole 3 is rotated 90 degrees around the pole axis, the instrument holder 4 is rotated at an angle of 25 ° C. obtained by subtracting the angle of 65 degrees where play is provided. The locked state of the lower instrument fixing piece 43 of the instrument holder 4 fitted and locked to 21 is released.

  Further, by rotating the attachment / detachment operation pole 3 by 90 degrees about the pole axis, the instrument holder fixing plate rotating tooth 311 of the pole head 31 rotates the instrument holder fixing plate 23 of the bracket 2 so as to form a bowl-shaped notch. The lock state of the upper lock part 45 of the instrument holder 4 fitted to the part 23a is released.

Through the above operations, the instrument holder 4 is in a state of being removed from the bracket 2 and is in a state of being placed and fixed on the instrument lifting platform 5 provided on the attachment / detachment operation pole 3.
Next, the operation button 33 of the attachment / detachment operation pole 3 is operated to lower the device lifting platform 5 in a state where the device holder 4 is placed and fixed, and move the device holder 4 to a position where work can be performed on the ground. .

Thereafter, the lamp 10 attached to the instrument holder 4 moved to the ground is replaced with a new one, or maintenance inspection is performed.
With the instrument holder 4 replaced with the new lamp 10 having undergone maintenance and inspection being fitted to the instrument extraction pin 51, the instrument lifting platform 5 is raised and the instrument holder 4 is accommodated in the bracket 2.

  The attachment / detachment operation pole 3 is rotated 45 degrees to the opposite side when the bracket 2 and the instrument holder 4 are unlocked, and the lower instrument fixing piece 43 of the instrument holder 4 is fitted into the lower lock hole 21 of the bracket 2. In addition to locking, the upper lock portion 45 of the instrument holder 4 is fitted and locked to the bowl-shaped notch 23a of the instrument holder fixing plate 23 of the bracket 2 by rotating 90 degrees.

  As described above, when the luminaire attaching / detaching device 1 is used, the detachable operation pole 3 is only operated from the ground even if the work is very troublesome, such as maintenance inspection of the luminaire at a high place and replacement of the lamp. Thus, it is possible to move the instrument holder 4 and the lamp 10 at hand, so that the work can be performed safely and easily.

The lighting fixture attaching / detaching apparatus according to the present invention is not limited to the above embodiment.
For example, in the above embodiment, the bracket 2 is attached to the utility pole P. However, even if the bracket is attached to a ceiling or a wall, it is possible to easily attach and detach the lighting fixture as described above. It is.

Further, the attachment / detachment operation pole 3 has been moved up and down the instrument lifting platform 5 by using a battery power source as a power source. For example, the attachment / detachment operation pole 3 can be manually moved up and down by using a member such as a reel used for fishing rods. It does not matter.
In addition, the fixture holder 4 is not limited to the lamp as illustrated, and may be configured to attach various lighting fixtures.

Since the lighting fixture attaching / detaching apparatus according to the present invention is configured as described above, a lighting fixture attached to a high place can be easily obtained without using a skilled technique without using an aerial work vehicle. It becomes possible to attach and detach.
Therefore, it is possible to save the trouble of obtaining permission to use the aerial work vehicle, and it is possible to keep the cost for replacing the lighting fixtures lower than before.
In addition, since it is not necessary to perform work at a high place, it is possible to ensure the safety of the worker.
Furthermore, since the lighting fixture attaching / detaching apparatus according to the present invention does not have a complicated configuration and can be manufactured at a low cost, the maintenance cost can be reduced.
