It is connected to.

  Here, a description will be given of a wire hanging method using the wire hanging jig 10 and the wire hanging device A of the present embodiment described above. 11 is a schematic diagram showing a suspended state of a suspended load, FIG. 12 is a schematic diagram showing a coupled state between a suspension hook and a connecting jig, and FIG. 13 is a schematic diagram showing a suspended state of a suspended load. . FIG. 14 and FIG. 15 are schematic diagrams illustrating the connection operation between the suspension hook and the connection jig.

  As shown in FIGS. 11 to 13, the wire hanging method according to the present embodiment includes a connecting jig 12 which is placed at a high place and has a vertical lower end to which a suspended load 72 is coupled via a suspending wire 71. This is a wire hooking method for connecting a hanging hook 11 suspended from a crane hook 74 via a crane wire 75, wherein the hanging hook 11 is moved in a horizontal direction toward a connecting jig 12 and horizontally moved from the connecting jig 12. A step of positioning the hook portion 25 provided at the lower end portion by lowering the suspension hook 11 below the guide portion 34, and a process of raising the suspension hook 11 to guide the suspension hook 11 upward. The method includes a step of being guided by the portion 34 to be locked in the locking hole 36 of the connecting jig 12, and a step of lifting the hanging hook 11 to suspend the suspended load 72 via the connecting jig 12.

  That is, as shown in FIG. 11, the holding bracket 13 is supported by a support cylinder P that is erected along a horizontal direction at a high place by support rings 54 and 55. The suspended load 72 is supported by the suspended wire 71, and the suspended wire 71 is connected to the suspended load connecting portion 33 of the connecting jig 12. The connecting jig 12 is moved horizontally by the holding pins 52 and 53 while the main body 31 enters the jig locking portion 56 of the holding bracket 13 and the locking plate 32 is placed on the holding plate 51. Is restrained. Therefore, the suspended load 72 is suspended and supported by the connecting jig 12 held by the holding bracket 13 via the hanging wire 71.

  When lowering the suspended load 72 on the floor for use, the operator operates the crane on the floor, connects the suspension hook 11 to the connection jig 12, and moves the connection jig 12 by the suspension hook 11. Then, the suspended load 72 is lowered to the floor.

  First, as shown by a solid line in FIG. 14, the worker operates the crane to move the hanging hook 11 in the horizontal direction toward the connecting jig 12 and extend the hanging hook 11 outward from the connecting jig 12. The pair of guide rods 41, 42 (guide portions 34) are positioned above the inclined portions 41b, 42b. Next, the hanging hook 11 is lowered by the crane. Then, the outer peripheral portion of the hook portion 25 comes into contact with the guide rods 41 and 42, and comes into contact with the first guide paths 41c and 42c of the inclined portions 41b and 42b, as shown by the two-dot chain line in FIG. While being guided, it is guided in the horizontal direction (left side in FIG. 14) away from the main body 31.

  Then, when the hanging hook 11 further descends and the hook 25 moves in the horizontal direction away from the main body 31 from the distal ends of the guide rods 41 and 42, the contact between the hook 25 and the guide rods 41 and 42 is released. The hook portion 25 of the suspension hook 11 is located below the guide rods 41 and 42 and below the inclined portions 41b and 42b, as shown by the solid line in FIG. In this case, when the hanging hook 11 descends, the position in the horizontal direction of the crane hook 74 (see FIG. 12) as a hanging fulcrum does not change, and only the hanging hook 11 has the inclined portions 41b of the guide rods 41 and 42. 42b moves horizontally. Therefore, when the contact between the hook portion 25 and the guide rods 41 and 42 is released, the suspension hook 11 moves directly below the crane hook 74 (see FIG. 12) as a suspension fulcrum. 11, the hook 25 moves below the inclined portions 41b and 42b.

  At this time, in the hanging hook 11, the first identification portion 28 faces the linear portions 41a, 42a of the guide rods 41, 42, and the second identification portion 29 faces the inclined portions 41b, 42b. By visually recognizing the positions of the identification portions 28 and 29 with respect to the connecting jig 12, the operator can grasp that the hook portion 25 of the suspension hook 11 has moved below the inclined portions 41b and 42b. Here, the operator operates the crane to raise the hanging hook 11.

  When the hanging hook 11 is raised, the shaft portion 22 (see FIG. 4) is raised between the pair of guide rods 41 and 42, and the outer peripheral portion of the hook portion 25 is brought into contact with the guide rods 41 and 42. As shown by the dashed line, while being in contact with the second guide paths 41d and 42d of the inclined portions 41b and 42b, the guide is guided in the horizontal direction (rightward in FIG. 15) approaching the main body 31. When the suspension hook 11 is further raised, the hook portion 25 comes into contact with the linear portions 41a, 42a from the inclined portions 41b, 42b of the guide rods 41, 42. Then, the hook portion 25 of the hanging hook 11 is guided by the linear portions 41 a and 42 a, and is finally locked in the locking hole 36.

  That is, as shown in FIGS. 1 to 3, in the hanging hook 11, the fitting portion 24 is fitted into the locking hole 36, and the hook portion 25 is in contact with the lower surface of the locking plate 32. Therefore, when the worker continues to operate the crane and raises the hanging hook 11, the hanging hook 11 lifts the connecting jig 12, raises it with respect to the holding bracket 13, lifts the suspended load 72, and lowers it on the floor. be able to.

  On the other hand, when the use of the suspended load 72 is completed, the worker suspends and supports the suspended load 72 on the connecting jig 12 held by the holding bracket 13 via the hanging wire 71 by the crane operation reverse to the above. . As shown in FIGS. 11 to 13, the hanging load 72 is supported by the hanging wire 71, and the hanging wire 71 is connected to the connecting jig 12. Further, the crane wire 75 of the crane hook 74 is connected to the suspension hook 11. Then, the operator operates the crane, connects the hanging hook 11 to the connecting jig 12, and raises the hanging hook 11 as it is. Then, the suspended load 72 can be lifted by the crane via the suspension hook 11 and the connection jig 12.

  Thereafter, the connecting jig 12 is moved in a horizontal direction toward the holding bracket 13 to be positioned above the holding bracket 13. Here, the hanging hook 11 is lowered to lock the connecting jig 12 with the jig locking portion 56 of the holding bracket 13. The hanging hook 11 is further lowered, and when the hook portion 25 is located below the guide rods 41 and 42, the hanging hook 11 is moved in the horizontal direction, so that the connection between the hook portion 25 and the connecting jig 12 is established. It is released.

  As described above, in the wire hanging jig of the present embodiment, the hanging hook 11 in which the wire connecting portion 21 of the crane is provided at one end in the longitudinal direction and the hook portion 25 is provided at the other end, Is provided with a hook connection portion 33 at one end thereof, a locking hole 36 for locking the hook portion 25 at the other end portion, and a guide portion 34 for guiding the hook portion 25 into the locking hole 36.
