The present invention relates to a fall prevention device for replacing an aviation obstruction light, which can be used when carrying a new aviation obstruction light or carrying a removed aviation obstruction light to the ground.

  In order to inform the aircraft of the position of an airway obstacle such as a power transmission tower, a high-rise building, or a chimney, an aviation obstacle light is installed at a high position such as the tip of the structure, the rooftop, or the wall surface. As shown in FIGS. 7A and 7B, such an aircraft obstruction light 51 has a structure in which a light source and a reflecting mirror are covered with a plastic light-transmitting globe 52 from above the lamp body. The globe 52 is integrated with a lamp lower part 54 attached to a power transmission tower, a high-rise building, or a chimney on the side of the aircraft obstacle light power transformer 53. For example, when the inside of the globe 52 such as a light source fails, only the globe 52 is removed for repair.

  The globe 52 and the lamp lower part 54 are opened in flange parts 55 in which a flange projecting horizontally around the lower part of the globe 52 and a flange projecting horizontally around the upper part of the lamp lower part 54 are overlapped. The bolts and nuts are joined to the through holes. Furthermore, the aviation obstruction light 51 is attached to the aviation obstruction light power transformer 53 by tightening fixing bolts 57 to two legs 56 attached to the aviation obstruction light power transformer 53. For example, when the aviation obstruction light 51 is broken or broken, the aviation obstruction light 51 is removed from the legs 56 of the aviation obstruction light power transformer 53 for repair.

Various techniques related to such an aircraft obstacle light have been proposed. For example, an aviation obstruction light having a structure as disclosed in Japanese Patent Application Laid-Open No. 2007-134172 “Aviation Obstruction Light Shading Device” has been proposed.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view illustrating a fall prevention device for replacing an aviation obstacle light according to a first embodiment. FIG. 2 is a front view showing a state in which the fall prevention device for replacing an aviation obstacle light according to the first embodiment is attached to the aviation obstacle light. FIG. 3 is a perspective view showing a state in which the fall protection device for replacing an aviation obstacle light according to the first embodiment is attached to the aviation obstacle light.
The fall prevention device 1 for aviation obstruction light replacement according to the first embodiment includes a lower holding portion 2 that is wound around a lower lamp body 54 below the flange portion 55 of the aviation obstruction light 51, and an upper portion of the flange portion 55 of the aviation obstruction light 51. This is an appliance comprising an upper holding part 3 that encloses the globe 52 and a connecting part 4 that connects the lower holding part 2 and the upper holding part 3. In the fall prevention equipment 1, when the aviation obstruction light 51 installed on the top of a steel tower, a building or the like is damaged or broken and is replaced, the aviation obstruction light power transformer 53 is used when the aviation obstruction light 51 is transported. Used when removing from (leg part 56).

  The lower holding portion 2 is a belt-like member made of cloth or flexible synthetic resin that wraps the lamp lower portion 54 below the flange portion 55 of the aviation obstacle light 51 so as to be detachable. The lower holding portion 2 is obtained by attaching the engaging portions 5 to both ends of a belt-like member formed longer than the periphery of the lamp lower portion 54, for example. The lower holding portion 2 is a portion that wraps the lamp lower portion 54 below the flange portion 55 of the aviation obstacle light 51 and functions as a retaining member.

  The upper holding portion 3 is a belt-like member having flexibility that wraps the globe 52 on the upper side of the flange portion 55 of the aviation obstacle light 51 so as to be detachably wound. The upper holding portion 3 is formed by attaching the engaging portions 5 to both ends of a belt-like member formed longer than the circumference of the globe 52, for example. In the illustrated example, the two upper holding portions 3 are provided, but the number is not limited to this number, and when the glove 52 of the aviation obstacle light 51 is long, it is preferable to increase the number. On the contrary, in the case of the globe 52 of the flat aviation obstacle light 51, one upper holding part 3 is sufficient.

The engaging portion 5 provided in each of the lower holding portion 2 and the upper holding portion 3 has a large number of loop-shaped materials planted at each tip of the belt-like member and a plurality of flexible hooks at the other tip. The material of the shape is planted. This hook-shaped material has a function of easily engaging with the loop-shaped material and connecting them together. However, if separation is performed with a force exceeding a predetermined level, the hook-shaped material and the loop-shaped material are deformed, and the hook-shaped material can be peeled off from the loop-shaped material, which functions as an engaging portion. It is.
Note that the engaging portion 5 is not limited to the hook-shaped material and the loop-shaped material, and hooks, buttons, or other types can be used. However, since it is handled at a high place, a structure that is lightweight and difficult to separate components is suitable.

  The lower holding part 2 and the upper holding part 3 are connected by a connecting part 4 as shown in FIG. 1 so that they are not separated from each other. The connecting portion 4 is a synthetic resin belt member made of cloth or flexibility, like the lower holding portion 2 and the upper holding portion 3.

  A grip portion 6 is attached to the upper holding portion 3 so that the fall prevention device 1 can be carried by hand with the aviation obstruction light 51 mounted. The grip portion 6 is also a belt-like member made of the same material as the lower holding portion 2 and the upper holding portion 3 or made of a synthetic resin having flexibility. Further, in order to increase the strength, as shown in FIG. 1, this gripping portion 6 has a single belt-like member attached continuously from the lower holding portion 2 to the upper holding portion 3 and functions as a connecting portion 4. It may be a

  A safety string 7 is connected to the grip 6. At the tip of the safety string 7, a hooking ring 8 for temporarily hooking on the body side of a worker or a nearby steel material is attached. The retaining ring 8 is used when two fall prevention devices 1 are connected.

Next, the usage method of the fall prevention device 1 of this invention is demonstrated.
The fall prevention device 1 according to the present invention provides a new aviation obstacle light when transporting a new aviation obstacle light 51 to a high place such as a steel tower, or when removing a damaged or failed aviation obstacle light 51 from the aviation obstacle light power transformer 53. When 51 is attached to the aviation obstruction light power transformer 53, the aviation obstruction light 51 can be used for any work when it is transported to the ground.

  First, when the aviation obstacle light 51 is transported to a high place such as a steel tower, the lower holding portion 2 of the fall prevention device 1 of the present invention is wound around the lower lamp body 54 below the flange portion 55 of the aviation obstacle light 51. . Next, the upper holding part 3 is wound around the globe 52 above the flange part 55 of the aviation obstacle light 51. In this manner, the aircraft obstacle light 51 is wrapped and carried with the grip portion 6. Furthermore, the safety string 7 connected to the gripping part 6 is hooked on the body of the person who works, and further prevention of falling is made. In this state, the aircraft obstacle light 51 is transported from the ground to a high place. At this time, the lower holding portion 2 functions as a retaining member at the flange portion 55, and the aviation obstruction light 51 is not detached from the fall prevention device 1, so that the fall can be prevented.

  When replacing a damaged or failed aviation obstacle light 51 at a high place, the lower holding part 2 and the upper holding part 3 of the fall prevention device 1 of the present invention are wound around the damaged aviation obstacle light 51, and the safety string 7 is attached. Hang it on the body of the worker. At this time, since the lower holding part 2 can be detachably attached by the engaging part 5, as shown in FIG. 2, it interferes with the leg part 56 for fastening the fixing bolt 57 provided on the aviation obstacle light power transformer 53. It is possible to wrap around the aviation obstacle light 51 attached to the aviation obstacle light power transformer 53 without any trouble. As described above, when the aviation obstruction light 51 is removed from the aviation obstruction light power transformer 53 (leg portion 56), the fall prevention device 1 of the present invention is mounted in advance, and the aviation obstruction light power transformer 53 (leg portion 56). The aviation obstruction light 51 can be prevented from falling even during the work of removing the fixing bolt 57 for the aviation obstruction light 51.

  When the new aviation obstruction light 51 is attached to the aviation obstruction light power transformer 53 (leg portion 56), the aviation obstruction light power transformer 53 (leg portion 56) is kept wrapped with the fall prevention device 1 of the present invention wrapped around. The mounting is completed by tightening the fixing bolt 57 of the aviation obstacle light 51. The fall prevention device 1 can easily attach the aviation obstacle light 51 without interfering with the fastening bolt 57 tightening. Even if the aviation obstruction light 51 is inadvertently detached from the aviation obstruction light power transformer 53 (the leg 56) before the fixing bolt 57 is tightened, the fall prevention device 1 can prevent the fall.

As described above, in the actual replacement work of the aviation obstacle light 51, it is convenient to use the fall prevention equipment 1 as a set of two. The first fall prevention device 1 is used when carrying a new aviation obstacle light 51, and the second fall prevention device 1 is made empty. A damaged or failed aviation obstruction light 51 is attached to the fall prevention device 1 in the second empty state. In this state, the aviation obstacle light 51 is removed from the aviation obstacle light power transformer 53 (leg portion 56).
Next, after the new aviation obstruction light 51 is attached to the aviation obstruction light power transformer 53, the first fall prevention device 1 is removed from the new aviation obstruction light 51.
On the other hand, the second anti-falling device 1 attached when removing the aviation obstacle light 51 is transported to the ground while being attached to the aviation obstacle light 51.

  Therefore, the fall prevention device 1 of the present invention does not cause a drop when transporting any of the new aviation obstacle light 51, the damaged damage that has been removed, or the failed aviation obstacle light 51. Further, when the damaged or failed aviation obstruction light 51 is removed from the aviation obstruction light power transformer 53 (leg portion 56), there is no possibility of dropping in any of the replacement work for attaching the new aviation obstruction light 51 thereto.

FIG. 4 is a partial front view showing a modified example of the engaging portion. FIG. 5 is a front view showing a state in which the fall prevention device having a deformed engaging portion is mounted on an aviation obstacle light, (a) is attached to a thin aviation obstacle light, and (b) is attached to a thick aviation obstacle light. It is in the state.
The fall prevention device 1 according to the present invention can be formed such that the engaging range of the engaging portion 5 is long in the longitudinal direction of the belt-like member. In this way, when the engaging range of the engaging portion 5 is wide, the engaging position can be freely adjusted. In view of this, the lower holding portion 2 has various sizes ranging from a thin aviation obstacle light 51 (see FIG. 5A) to a thick aviation obstacle light 51 (see FIG. 5B) with a single fall prevention device 1. Can correspond.

FIGS. 6A and 6B are perspective views showing a fall prevention device according to the second embodiment, in which FIG. 6A shows a state where it is attached to an aviation obstacle light, and FIG.
The fall prevention device 21 of the second embodiment is substantially the same as the first embodiment, but the both ends of the belt-like member of the upper holding portion 22 are not detachable. The upper holding portion 22 of the second embodiment is an endless belt having substantially the same length as the outer periphery of the globe 52.

In the fall prevention device 1 of the present invention, the lower holding portion 2 has a fixing bolt 57 for the aviation obstacle light 51 and an aviation obstacle light power transformer 53 when the aviation obstacle light 51 is mounted on the aviation obstacle light power transformer 53. It is necessary to provide the engaging portion 5 so as to be detachable so as not to interfere with the leg portion 56 (see FIG. 2). However, since the upper side holding part 22 of Example 2 should just hold | maintain so that the aviation obstruction light 51 may be wrapped, it is not necessary to necessarily comprise a belt-shaped member so that attachment or detachment is possible. Therefore, in the fall prevention device 21 of Example 2, the upper holding part 22 is an endless belt having substantially the same length as the outer periphery of the globe 52. Thereby, the quickness of work improves.
Although not shown in the drawings, the upper holding portion can be configured in a simple bag shape or in a bag shape in which the inside can be visually confirmed.

  Furthermore, as a modification of the upper holding portion 22 of the second embodiment, an endless belt having substantially the same length as the outer periphery of the globe 52 can be made of a rubber-made material having elasticity. Even in such a configuration, the aircraft obstacle light 51 can be held so as to be wrapped. The function of preventing fall can be maintained.

In the present invention, the flange portion 55 of the aviation obstruction light 51 is used for retaining, so that the aviation obstruction light 51 can be transported while being prevented from falling, and the aviation obstruction light 51 can be transported with the aviation obstruction light power transformer 53 ( The fall prevention device 1 can be attached without interfering with the leg 56), and the fall prevention device 1 is mounted in advance when the aviation obstruction light 51 is removed from the aviation obstruction light power transformer 53 (leg 56). In this state, the aviation obstruction light power transformer 53 (the leg 5
If the fall of the aviation obstacle light 51 can be prevented when the fixing bolt 57 for the aviation obstacle light 51 is removed from 6), the invention is not limited to the above-described embodiment of the invention and is within the scope of the present invention. Of course, various changes can be made.

  The fall prevention device for aviation obstacle light replacement according to the present invention can be used not only for aviation obstacle light replacement work but also for replacement of illuminating lamps at high places.
