DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable illuminator which is used for maintenance and inspection of a pole-type illuminator for roads, such as replacement of defective lamps and cleaning of illuminators.

[0002]

2. Description of the Related Art Conventionally, in a pole lighting device for a road, a lamp portion is directly attached to a pole which is a supporting structure.

FIGS. 3 and 4 show a replacement work and a configuration of a conventional pole-type lighting device for a road. In the case of the conventional lighting device, a glass cover which is a light emitting surface is used for the purpose of maintaining a constant illuminance. As shown in FIG. 3, the cleaning of the parts and the replacement work when the lamp of the light emission source is burned out are performed by the worker on the deck 13 using the aerial work vehicle 12.

As shown in FIG. 4, a lamp 7 directly attached to a road pole 6 has a structure in which an outer cover 7 including a light emitting glass surface 8 is opened and closed with a hinge 11 as a fulcrum. Work such as replacement of the light source lamp 10 has been performed by opening and closing this cover. Reference numeral 9 denotes a reflecting surface provided inside the lamp, and 14 denotes a hydraulic lifting / lowering boom.

[0005]

By the way, in the above-mentioned conventional pole-type lighting device for a road, an aerial work vehicle is used, and an operator rides on a work deck of the aerial work vehicle 12 stopped at the shoulder of a road, and a boom. Since the maintenance inspection work is performed by extending the extension 14, the following inconveniences occur.

(1) It is dangerous to work at heights.

(2) In addition to the above (1), work efficiency is poor due to work on a narrow limited deck.

(3) Due to the work, lane regulation must be performed, which is a factor of traffic congestion.

(4) The number of workers engaged in so-called 3K work such as tight, dirty and dangerous is decreasing.

(5) When performing mechanical work using a robot manipulator or the like, complicated operations are required, and it is difficult to implement a device.

An object of the present invention is to provide a new road pole-type lighting device that solves the above-mentioned disadvantages.

[0012]

In order to achieve the above-mentioned object, a detachable lighting device according to the present invention has a joint detachable socket mounted on the upper end of a road pole accommodating an energizing cable and a ground wire therein. An illumination lamp comprising a lamp, a glass surface, and an internal reflection surface provided at a base thereof with a detachable socket for a joint detachable from the socket can be easily attached to and detached from the detachable socket provided at the upper end of the road pole by male and female connections. It is characterized by having been constituted.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; 1A and 1B show an example of a detachable lighting device according to the present invention, wherein FIG. 1A is a plan view, FIG. 1B is a side view, FIG.
Is an enlarged view of the removable socket of the detachable lighting fixture,
(A) is a cross section and a side view of a female removable socket, and (b) is a cross sectional and side view of a male removable socket.

In FIG. 1, the lighting fixture includes an outer cover 7,
A light-emitting surface glass cover 8, a reflection surface 9 inside an outer cover, and a light-emitting source lamp 10. The cover including the glass surface 8 can be opened and closed with a hinge 11 for opening and closing the cover as a fulcrum, and the light-emitting source lamp 10 can be replaced. Have been.

The base of the illumination lamp is connected to the upper end of the road pole 6 by means of screw-type joints 1 and 1 ', for cleaning the light-emitting surface glass cover 8 and the internal reflection surface 9 of the outer cover 7, and for the light-emitting source lamp 10. The work such as replacement can be performed while the lamp is mounted on the pole 6, and can be removed by the joints 1 and 1 '.

Further, even in the case of the work of only replacing the lamp, the cover including the glass surface 8 is opened with the hinge 11 as a fulcrum and the replacement is possible as in the conventional case.

FIGS. 2 (a) and 2 (b) are enlarged views of a joint for connecting the pole and the lamp of the detachable illumination lamp according to the present invention, wherein the upper end of the pole 6 and the base of the lamp comprise a male and female detachable socket. 1, 1 '.

A single-phase power cable and a ground wire 5 are housed inside the road pole 6 and are connected by a three-core connector 2 at a joint of a detachable socket (female type) 1 '.

Reference numeral 3 denotes a pin for preventing loosening, and reference numeral 4 denotes an O-ring for waterproofing.

Similarly, a detachable socket (male type) 1 having a built-in cable and ground wire is attached to the base of the lighting fixture, and a connector 2 is connected in the socket.

Next, the operation of the present invention will be summarized as follows. (1) By separating the pole and the lamp separately,
Replacement and cleaning of lamps and maintenance and inspection of lamps It is no longer necessary to perform dangerous, inefficient and unstable work at high places throughout the entire transportation. Can be

(2) The joint between the pole and the lamp is a male-female joint socket type, so that work time at high places can be reduced and work efficiency can be improved. In addition, the socket is provided with a screw-type drop prevention mechanism so that the socket does not come off due to vibration, so that the socket becomes more reliable.

(3) Further, from the above, mechanization and simplification of the work can be achieved by using a separate robot manipulator or the like.

[0024]

As described above, according to the detachable lighting device of the present invention, the following effects can be obtained.

(1) The work of replacing the entire lamp is simplified by separating the pole and the lamp and the joint for connecting them is a socket type, and the work such as cleaning lamp replacement and inspection is performed by replacing the entire lamp. You can do it all at once. As a result, not only can the work efficiency be improved, but it can also contribute to the improvement of 3K work such as tight, dirty and dangerous.

(2) Since the entire operation is simplified, the operation by a machine such as a robot manipulator can be easily controlled.
