Description

Street lamp lighting equipment lift equipment

The present invention relates to a luminaire lifting and lifting device for a streetlight fixedly installed to illuminate a road, and more specifically, to a fixing member in which a plurality of winding guide rollers are built inside a streetlight post under a streetlight and a guide nut of a lifting screw. After installing a lift device consisting of a screw-type movable member, the lifting wire with one end fixed to the winding guide roller installed on the fixing member and the movable member of the lift device is wound in a zigzag manner to be guided, and connected and fixed with the light fixture. By allowing the luminaire to be raised and lowered during the replacement and maintenance work of the luminaire, it can be operated smoothly and easily without twisting and no twisting of the elevating wire, as well as to ensure the safety of the operator through the replacement and maintenance of the luminaire. It relates to a lift device.

In general, if the length of a streetlight to illuminate a roadway or sidewalk is 10m or more, and you need to replace or repair a streetlight luminaire in a streetlight pole, the worker climbs a ladder or climbs a crane with a basket to perform the repair work. What was doing is a well-known fact.

However, the maintenance work for conventional streetlights as described above was not only exposed to safety accidents due to the high risk of falling of the worker or the risk of electric shock from high-voltage lines, but also the operation was limited because the worker had to climb the ground and perform maintenance work. It is cumbersome and inconvenient, as well as delays in maintenance work, and requires mobilization of special vehicles such as cranes, which are expensive due to the maintenance work, and requires a large number of workers. There was a problem that the traffic flow was obstructed, and the risk of traffic accidents followed, and expensive equipment and maintenance or replacement time delays caused the increase in expensive facility management costs.

Accordingly, in recent years, in order to solve the problems related to the maintenance of streetlights, the invention of folding the upper and lower streetlight posts when replacing and repairing lighting fixtures has been developed to solve the above problems. It has been disclosed as Korean Patent Application Publication No. 10-2005-0052806 (published on June 7, 2005).

Here, the above Patent Publication No. 2005-0052806 can fold the post for the street light when replacing or repairing the luminaire of the street light, but it is possible to fold the post for the street light in a desired direction depending on the roadway, sidewalk or surrounding situation. If an unexpected obstacle occurs in the direction to be folded because the existing technology is not presented, there is a problem in replacing or repairing the luminaire by folding the post for the street light, and as a solution to this problem, Korean Patent Publication No. 2007 No. -0019446 (published on February 15, 2007) has been disclosed.

However, the above-described Patent Publication Nos. 2005-0052806 and 2007-0019446 have a problem that the length of the upper street lamp to be folded is enormous because the folding position is at the position where the folding is operated.

In other words, streetlights that are 7 to 8 meters long and 15 to 20 meters long are used. Assuming that such a long street light is folded from the lower side, there is a problem that it blocks the roadway and even the other lane.

In other words, this is because the operating position takes into account the degree of the operator's eye level, and there is a hinge portion that is folded at this height.

In consideration of the above problems, the present applicant came up with an invention to make repair and replacement work by lifting only the luminaire when repairing or replacing luminaires for street lights, and applied for a patent to the Korean Intellectual Property Office ( No. 10-2016-0044424), and after undergoing examination, the patent was registered (registration No. 10-1810101) on December 12, 2017.

However, the functional streetlight previously applied and registered by the present applicant includes a winding device that is installed on the upper surface of the foundation block as the lower inner side of the lower streetlight column among the upper and lower streetlight columns, so that only the luminaire can be selectively lowered to the road surface. In order to facilitate maintenance of the luminaires such as replacement work or maintenance work for the internal lamp, the luminaire installed on the upper street lamp post was lowered to the lower ground to facilitate maintenance and replacement work. As it is formed of a single bobbin, when the weight of the luminaire is suspended and fixed, the lifting wire is twisted or pinched between the wire to be wound by the luminaire's own weight, so that the luminaire can be replaced or repaired. There are problems in that the descending operation does not occur when descending, and there is a limitation in lengthening the lifting wire in a narrow space since winding or unwinding by using one bobbin.

Therefore, by allowing the luminaire to be raised and lowered in original style while selectively preventing the twisting and tingling of the elevating wire from the upper and lower light poles of the streetlight, it is possible to easily replace and repair the luminaire. Research and development are required.
