As a result, even if the worker falls from a ladder or the like, it is possible to prevent the wire 31 from coming into contact with the outer edge of the ceiling section 22, and it is possible to prevent the wire 31 from coming into contact with the outer edge of the ceiling section 22 when the worker falls. It becomes possible to direct such force in a vertically downward direction (Z2 direction). Therefore, even if the worker falls from a ladder or the like, the wire 31 can be prevented from coming into contact with the outer edge of the ceiling section 22 and the wire 31 can be prevented from being cut due to this contact. This makes it possible to prevent injury to the worker himself and damage to the equipment 20 to which it is attached.

Note that in the safety belt attachment device 10, for example, if the center position of the annular shape of the ring portion 12b is located outside the side surface of the device main body 21, the entire ring portion 12b is located outside the side surface of the device main body 21. It may not be located in

Then, the worker attaches the safety belt 30 to the safety belt attaching device 10 by hooking the hook 32 to the ring portion 12b, and then starts work at the work place (step S12 in FIG. 7). Note that the work place is, for example, the surface of the ceiling 22 of the device 20 to be mounted on the Z1 direction side (i.e., the top surface of the device 20 to be mounted), or a place near the ceiling 22 (for example, a place near the device 20 to be mounted). (the top surface of other equipment placed in the area), etc.

Thereafter, for example, when the worker has finished working at the work site, the worker removes the safety belt 30 from the safety belt attachment device 10 by removing the hook 32 from the ring portion 12b (step S13 in FIG. 7). Further, the worker removes the safety belt attachment device 10 from the target device 20 by removing the threaded portion 11b of the safety belt attachment device 10 from the screw hole portion 23 of the device 20 to which the safety belt is attached (step S14 in FIG. 7). ).

Further, the attachment method in this embodiment includes, for example, a step of attaching a moving device 24 for moving the attachment target device 20 in a predetermined direction to the attachment/detachment structure 23 before the step of attaching the attachment structure 11b; The process includes a step of moving the attachment target device 20 in a predetermined direction by the moving device 24, and a step of physically removing the moving device 24 from the attachment/detachment structure 23.

Specifically, the attachment/detachment structure 23 is provided, for example, on the upper surface of the attachment target device 20, and the predetermined direction is the Z direction (vertical direction). In addition, in the step of mounting the mounting structure 11b, for example, the mounting structure 23 is attached so that the position of the connection member 12 (ring portion 12b) on the XY plane (horizontal direction) is outside the side surface of the device main body 21. Then, the mounting structure 11b is mounted. Further, the instrument main body 11 is, for example, a rod-shaped member, and the connecting member 12 is attached to the side surface of the instrument main body 11, for example.

More specifically, the attachment/detachment structure 23 is, for example, a screw hole portion 23, and the attachment structure 11b is a screw portion 11b, and in the step of attaching the attachment structure 11b, the screw portion 11b is screwed into the screw hole portion 23. do.

Thereby, the worker can, for example, hook the hook 32 of the safety belt 30 onto the safety belt attachment device 10 that is fixed to the equipment 20 to be attached. Therefore, even if the worker is working at a high place, for example, it is possible to ensure safety during work without building a scaffold to hang the hook 32 of the safety belt 30. .

Note that the length of the fixing portion 12a extending from the device body 11 (the length on the The position of the portion 12b may be determined to be outside the side surface of the device main body 21.

Further, in the above example, a case has been described in which the instrument main body 11 has the rod-shaped portion 11a, but the present invention is not limited to this. Specifically, the instrument main body 11 may include, for example, a member having at least a partially curved shape (for example, a dogleg-shaped member or a U-shaped member) instead of the rod-shaped portion 11a.

Furthermore, in the above example, a case has been described in which the ring portion 12b is fixed on the side surface of the end portion (the end portion in the Z1 direction) of the rod-shaped portion 11a, but the present invention is not limited to this. Specifically, the ring portion 12b may be fixed, for example, at a position other than the side surface on the end side of the rod-shaped portion 11a (for example, the side surface near the center in the Z direction).

Further, the length of the safety belt attachment device 10 (the length in the Z direction) is determined, for example, according to the height of the attachment target device 20 (that is, the height of the ceiling portion 22 of the attachment target device 20). It may be. Specifically, the length of the safety belt attachment device 10 is, for example, the height of the ring portion 12b when the safety belt attachment device 10 is attached to the device 20 to be attached (i.e., the height of the hook 32 of the safety belt 30). height) may be determined to be a predetermined height from the viewpoint of ensuring worker safety. More specifically, the length of the safety belt attachment device 10 may be, for example, about 400 (mm).

[Modification of safety belt attachment device 10 in the first embodiment]
Next, a modification of the safety belt attachment device 10 in the first embodiment will be described. FIG. 8 is a configuration diagram of the safety belt attachment device 10 in a modified example.

For example, a hollow position adjustment member 15 (hereinafter also referred to as elastic material 15) may be attached to the threaded portion 11b of the safety belt attachment device 10. The elastic material 15 may be, for example, a rubber sheet.

Then, the operator attaches the threaded part 11b to the threaded hole part 23 of the mounting target equipment 20 by, for example, penetrating the threaded part 11b into the hollow part of the elastic member 15. The safety belt attachment device 10 may be fixed thereto. In other words, the operator fixes the safety belt attachment device 10 to the device to be attached 20 with the elastic material 15 squeezed between the lower end of the device body 11 and the ceiling portion 22, for example. It's okay.

That is, the operator attaches the safety belt attaching device 10 to the attachment target device 20, for example, by screwing the threaded portion 11b into one of the screw holes 23. In other words, the operator attaches the safety belt attachment device 10 by, for example, rotating the ring portion 12b around the device body 11 as the rotation center. Therefore, when the installation of the safety belt attachment device 10 is completed, the position of the ring part 12b may not be on the outside of the side surface of the device main body 21, depending on the length of the threaded part 11b that is screwed into the screw hole part 23, for example.

The length of the portion 11b is adjusted to be short.

This allows the operator to, for example, adjust the position of the ring portion 12 after the safety belt attachment device 10 is attached. Therefore, the operator can adjust the position of the ring part 12b in the horizontal direction to be outside the side surface of the device main body 21, for example, regardless of the length of the threaded part 11b.

As described above, in the mounting method according to the present embodiment, in the step of mounting the mounting structure 11b, for example, the position of the connecting member 12 (ring portion 12b) in the horizontal direction is outside the side surface of the device 20 to be mounted. The position adjustment member 15 for adjusting the position of the connection member 12 is inserted between the attachment and detachment structure 23 and the attachment structure 11b so that attachment of the attachment structure 11b to the attachment and detachment structure 23 is completed in this state.

Specifically, in the step of mounting the mounting structure 11b, for example, the elastic material 15 as the position adjustment member 15 is inserted between the mounting structure 23 and the mounting structure 11b.

As a result, even if the worker falls from a ladder or the like, it is possible to prevent the worker from colliding with the target device 20, resulting in injury to the worker himself or damage to the target device 20. It becomes possible to prevent
