FIG. 11 is an explanatory diagram for explaining a comparative example with respect to the present embodiment. As shown in the figure, when work such as maintenance of the switchboard 100 is performed on the upper surface 101 of the switchboard 100 accommodated in a device having a height exceeding 2 m, in this example, the chassis 111, the master rope 121 is used. It is necessary for the operator 200 to wear the safety belt 122 attached to the master rope 121 and work. In this case, the scaffold 123 is assembled on both sides of the switchboard 100, the support column 124 is erected, and the master rope 121 is attached.
However, in order to assemble the scaffold 123, a preliminary survey is required, and work time for assembling the scaffold 123 is also required. In addition, since the scaffold 123 is assembled on the side of the switchboard 100, the scaffold 123 may interfere with another worker 200 working on the side of the switchboard 100 at the same time.

Therefore, in the following, a description will be given of the present embodiment that solves such a problem.
FIG. 1 is a front view of a master rope attaching jig 1 of the present embodiment. FIG. 2 is a top view (a), a front view (b), and a cross-sectional view (a) taken along the line AA of the base 2 constituting the master rope attaching jig 1. FIG. 3 is a front view (a), a right side view (b), and a top view (c) of the column 3 constituting the master rope attaching jig 1. FIG.

  The base 2 has a bolt hole 103 (from above) from which a lifting member 102 bolted to lift the switchboard 100 is lifted to an upper surface 101 of the switchboard 100 housed in a casing in a predetermined device, in this example (see FIG. 6). , See FIG. 6), and is a device for fixing to the upper surface 101 of the switchboard 100. The base 2 is constituted by a metal fitting such as L-shaped steel in which a plurality of holes 21 for bolting to the upper surface 101 of the switchboard 100 through bolts is formed.

  In the base 2, support attachment members 4 for attaching the support 3 to the base 2 are attached to a plurality of locations in the direction of the upper surface 101 of the switchboard 100 (see FIG. 7), specifically, the upper surface 101 of the switchboard 100. 2 is provided at a plurality of locations along the longitudinal direction. Thereby, the attachment position of the support | pillar 3 can be selected from the said several places. The column attachment member 4 includes an insertion port 41 for inserting one end side of the column 3, and has a hole 42 for bolting the column 3.

The support column 3 is made of, for example, L-shaped steel, and the master rope mounting member 5 (see FIGS. 4, 5, and 8) is attached to two steel plates 31 and 32 having different surface-direction angles of the L-shaped steel. A plurality of holes 33 are formed side by side in the longitudinal direction. Moreover, the support | pillar 3 is attached to the base 2 by making the length direction into an up-down direction by inserting one end side in the insertion port 41, and bolting.
The master rope attaching member 5 (see FIGS. 4, 5, and 8) is a metal fitting or the like that is provided on the support 3 and attaches the master rope 6 to the support 3. Specifically, the master rope attaching member 5 is bolted and attached to the hole 33 of the column 3.

The top view of FIG. 4 shows the master rope attaching jig 1 in which the pillar 3 is attached to the base 2 and the master rope 6 is bridged by the master rope attachment member 5 between the two struts 3 facing each other.
Further, as shown in the side view of FIG. 5, the removed lifting member 102 may be attached to the support column 3 as the master rope attachment member 5. 4 and 5, the bolts for fastening the respective parts are not shown (details will be described later).

Next, a jig mounting method for mounting the master rope mounting jig 1 having the above configuration to the switchboard 100 will be described.
(1) First Step First, as shown in FIG. 6, the worker 200 removes the lifting member 102 that is bolted to lift the switchboard 100 on the upper surface 101 of the switchboard 100. After removing the lifting member 102, the bolt holes 103 are exposed on the upper surface 101 of the switchboard 100.
(2) Second Step After the first step, as shown in FIG. 7, the operator 200 bolts the base 2 with the bolt 151 to the bolt hole 103 on the upper surface 101 after removing the lifting member 102, The base 2 is fixed to the upper surface 101 of the switchboard 100.

(3) Third Step After the second step, as shown in FIG. 8, the worker 200 attaches the support column 3 to the support mounting member 4 of the base 2 with the length direction as the vertical direction. That is, one end of the column 3 is inserted into the insertion port 41 of the column mounting member 4, and the bolt 152 is inserted into the hole 42 of the column mounting member 4 and the hole 33 of the column 3 to connect the column mounting member 4 and the column 3. Bolt.
In addition, the worker 200 attaches the master rope attaching member 5 (in this example, the lifting member 102 removed in the first step) to the support column 3 as described above.

(4) Fourth Step After the third step, as shown in FIG. 9, the worker 200 attaches the master rope 6 to the master rope attachment member 5 provided on the column 3. Then, the worker 200 can work safely on the switchboard 100 by connecting one end of the safety belt 122 to the master rope 6 and attaching the other end to the body.
Thus, by attaching the master rope attaching jig 1 to the switchboard 100, the jig-equipped device 10 is completed as a whole.

  In the example of FIG. 9, the master rope 6 is only stretched in a partial area on the switchboard 100, but as shown in FIG. 10, a large number of master rope attachment jigs 1 are attached to the switchboard 100. It may be installed in a wide area on the upper surface 101, and the master rope 6 may be stretched so that the worker 200 can work in a wide range on the switchboard 100.

  According to the present embodiment described above, the master rope 6 can be stretched on the switchboard 100 without assembling the scaffold 123 as in the comparative example of FIG. Therefore, the preliminary survey for assembling the scaffold 123 is unnecessary, and the work time for assembling the scaffold 123 is also unnecessary. Further, the scaffold 123 does not interfere with another worker 200 working at the side of the switchboard 100 at the same time. Therefore, according to the present embodiment, the master rope attaching jig 1 capable of installing the master rope 6 can be installed easily and without interfering with maintenance work or the like on the switchboard 100. The apparatus 10 and the jig mounting method can be provided.

In addition, support attachment members 4 are provided at a plurality of locations in the longitudinal direction of the base 2. Therefore, according to the present Example, the attachment position of the support | pillar 3 can be selected from several places.
Furthermore, when the lifting member 102 removed from the switchboard 100 is used as the master rope attachment member 5 (FIGS. 5 and 8), the number of parts of the master rope attachment jig 1 is reduced, and the manufacturing cost is reduced. Can do.

  In addition, the column 3 is L-shaped steel in which holes 33 for attaching the master rope attaching member 5 are formed in two steel plates 31 and 32 having different angles in the plane direction. Therefore, it is possible to reduce the weight of the support column 3 to facilitate the work, and to increase the variation in the direction in which the master rope attachment member 5 is directed and to easily stretch the master rope 6 in various directions. Become.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Moreover, it is also possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
