The present invention relates to an improvement in a hanging tool for hanging a tubular body such as a metal pipe by hooking both ends thereof.

フツクの掛け外しは期待できなかつた。 In the conventional hanging device of this kind, as shown in Fig. 1, when the hook 2 is hung on or removed from the tubular body 1, the hook 2 is fixed to the telescoping beam 3, so the moving speed of the hook is the same as the telescoping speed of the telescoping beam. Therefore, the time required for hooking and unhooking must depend on the speed of expansion and contraction of the telescopic beam, and rapid hooking and unhooking could not be expected.

される。 The object of the present invention is to consist of a fixed beam 4 and a pair of telescopic beams 5 guided within the fixed beam and extendable and retractable in opposite directions, each of which is provided with a hook 6 at its tip. In a hanging device that uses a hook to hook both ends of a tubular body 1 such as a metal pipe, the upper end of the hook 6 is pivoted to a bracket 7 provided at the tip of a telescoping beam 5 with a pin 10, and the other end of the tubular body 1 is beam 5
A hollow stopper receiver 13 installed in the tip of the
The tip of the piston 9, which is guided so as to be movable in the axial direction of the telescopic beam 5 by means of a telescopic driving means disposed within the telescopic beam, is attached to the hook 6 by a pin 11 at a position below the pin 10. Attach the shaft with
At that time, the rotation of the hook 6 around the pin 10 due to the movement of the piston 9 causes the hook 6 to rotate due to the retreat of the piston 9, and the surface of the hook 6 facing the end surface of the telescopic beam 5 is When the hook 6 makes contact, the hook 6 is limited to the engaged position, and the rotation of the hook 6 to the released position due to the advancement of the piston 9 is limited to the stopper 1 provided on the piston 11.
2 is configured such that it is restricted by contacting the rear end surface of the stopper receiver 13, and after the rotation of the hook 6, the driving force of the piston 9 is transferred to the telescopic beam 5.
When the telescopic beam 5 is extended, it is transmitted to the telescopic beam 5 through the stopper 12, and when the telescopic beam 5 is contracted, the transmission is transmitted to the telescopic beam 5 through the hook 6. achieved.

て伸縮ビーム５は後退することになる。 Figure 3 shows the structure of the main parts of the hanging tool of the present invention (the beam structure on the left side is omitted because it is symmetrical), and Figure 4 is a partially cutaway perspective view of the main parts, where 4 is fixed. A beam 5 is a telescoping beam guided within the fixed beam 4, and 6 is a bracket 7 fixed to the tip of the telescoping beam 5, the upper end of which is rotatable.
A hook is pivotally connected by a pin 10, 8 is a power cylinder provided inside the telescoping beam 5, and 9 is a piston guided movably within the telescoping beam 5 by the power cylinder 8. The tip of the piston 9 is pivotally connected to the hook 6 by a pin 11, and the hook 6 can be rotated by the movement of the piston 9 about the pin 10 as a rotation axis from the position shown by the solid line to the release position shown by the broken line. ing. 12 is a stopper provided on the piston 9, and 13 is a stopper receiver fixed to the inner cavity of the tip end of the telescopic beam 5. The piston 9 is guided by the stopper receiver 13. The position of the stopper 12 is the piston 9.
When the hook 6 is brought from the hook 6 position shown in FIG. 3 (solid line) to the hook 6 rotation position (released position) shown in FIG. It is set so as to come into contact with the stopper receiver 13. After the stopper 12 comes into contact with the stopper receiver 13, the piston 9 moves further, so that the telescopic beam 5 is extended. When the piston 9 moves back from this state, the hook 6 first rotates from the position shown in FIG. 5 to the position shown in FIG. It comes into contact with the front end surface of the telescopic beam 5. Further, as the piston 9 moves backward, the telescopic beam 5 moves backward.

本考案の吊具におけるフツクの掛け外しが従来
の吊具よりも迅速に行なわれることを図面により
説明する。 It will be explained with reference to the drawings that the hanging tool of the present invention allows the hook to be hung and removed more quickly than the conventional hanging tool.

第５図の状態にもたらされるためにピストン９が
推移した距離をl₁で示す。 Assume that the hook 6 is engaged with the end of a tubular body (not shown) in the state of the hook 6 shown in FIG. When the hook 6 is rotated from this state as shown in FIG. 5, the hook 6 is removed from the end of the tubular body.
The moving distance of the tip of the end surface of the hook 6 on the end side of the tubular body at this time is shown as _L1 in FIG. The distance traveled by the piston 9 to bring the hook 6 into the position shown in FIG. 5 is also designated by l ₁ .

う。 By the way, as shown in FIG. 6, in a conventional hanging device in which the hook 6' does not rotate (for convenience of explanation, a hanging device having the same structure as the hanging device of the present invention is shown), the hook 6' In order to release the engagement from the end of the tubular body, the end surface of the hook 6' on the tubular body side must be
As in the case shown in the figure, it is necessary to move the hook 6 a distance L ₁ from the engagement position (Fig. 3), but in order to move the hook 6 this distance L ₁ from the position shown in Fig. 3,
The piston 9, ie the telescopic beam 5', must be displaced an additional distance _l2 - _l1 , which is greater than _l1 . Similarly, it will be obvious from the above description that engaging the hook 6' with the end of the tubular body requires more time than in the case of the hanger of the present invention.

である。 As is clear from the above description, the hanger of the present invention has the practical effect of being able to quickly attach and detach the hook from the end of the tubular body.
