【考案の詳細な説明】 〈産業上の利用分野〉 本考案は、揚重吊具用ハッカーに関し、被揚重物から
の離脱を自動的に可能ならしめる前記ハッカーに関す
る。[Detailed Description of the Invention] <Industrial field of application> The present invention relates to a hacker for lifting hoist, and relates to the hacker for automatically allowing a lifted object to be detached.
〈従来の技術〉 例えば断面形状が矩形をした重量物である厚板、ある

る。<Prior art> For example, when a heavy object such as a heavy object having a rectangular cross section or a heavy object such as a box-like object is lifted by a crane and transported, it is locked at the lower end as shown in FIG. A means for lifting via a hacker 10 having a claw 17 is often adopted. That is, the hacker 10 is engaged with the wire 12 hanging from the crane hook 11, and the lifting object 13 is locked by the locking claw 17 provided at the lower end of the hacker 10, and then the crane hook 11 is rolled up. This makes it possible to carry.

作業者がハッカー10を外側に引寄せて離脱させることが
普通であった。By the way, when lowering the load 13 to be lifted by the above means to a predetermined storage place, it is necessary to separate the hacker 10 from the load 13 to be lifted. This detaching work is conventionally performed by installing a ring 14 in advance in the yard and providing a space 16 between the yard surface 15 and the lower surface 13a of the object 13 to be lifted so that the locking claw 17 can be removed. After lowering the heavy items 13 onto the ring 14,
It was common for an operator to pull the hacker 10 outward and detach it.

面にも大きな問題があった。<Problems to be solved by the invention> However, in such a method, the ring 14 is required, and a loss space for installing the ring 14 is generated, or the ring 14 is installed or hackers are installed. There were problems such as requiring an operator to pull in 10. On the other hand, under the constraint condition of the storage space, for example, in a narrow hold, or under the situation that the stacking as shown in FIG. 3 described later has to be performed, it is often the case that the above-mentioned ring 14 cannot be installed. In such a case, in the conventional means, the operator can lift the object 13 to be lifted from the yard surface 15 using various jigs, and can only take out the hacker 10, and the work efficiency is extremely poor. There was a large physical burden on the operator, and there was a major safety problem.
本考案は、前述したりんがね14の設置ができないよう
な状況下においても、被揚重物13からハッカー10を人力

課題とするものである。An object of the present invention is to provide a hacker that automatically detaches the hacker 10 from the object to be lifted 13 without requiring human power even in the situation where the ring girder 14 described above cannot be installed. .

る。<Means for Solving the Problems> The present invention relates to a lifting device which is attached to both ends of a plate-like object to be lifted and is used to suspend the object to be oscillated in a downward-opening radial pattern. A hacker for lifting equipment, an upper arm part having an upper end connected to the crane side, and a lower arm part provided with a locking claw protruding inward at the lower end to lock the object to be lifted. A 7-shaped hacker in which a through hole for mounting a shaft is formed in a bent portion connected in a V shape is provided at a position higher than the length from the center of the through hole to the lower end of the lower arm portion. From one side, it is rotatably supported by the support member via the shaft.

7 is a hacker having 2 and 2 is a locking claw provided at the lower end of the lower arm 2b of the hacker 1. A through hole 3 is formed in the bent portion of the upper arm portion 2a and the lower arm portion 2b of the hacker 1. Reference numeral 4 denotes a support member, which is swingably suspended via a shaft 5 inserted and held in the through hole 3 shown in FIG. As shown in FIG. 2, the support member 4 has an arm length L longer than the length 1 from the through hole 3 to the tip of the locking claw 2, and is configured to enclose the lower arm portion 2b described above. Has been done. The hacker 1 in this embodiment is constructed by connecting two steel plates 1a by a connecting member 1b, and the supporting member 4 is formed by wrapping the hacker 1 between left and right members 4a. Has been done.
In FIG. 2, reference numeral 4b represents a connecting tool for connecting the member 4a.
次に本考案のハッカー１の作用について説明する。 Next, the operation of the hacker 1 of the present invention will be described.

脱する。FIG. 3 shows an embodiment in which thick steel plates 13a are stacked, and the thick steel plates 13a 1 lifted by the hacker 1 are hung on the thick steel plates 13a 2 stacked previously. Is shown. The supporting member 4 in the lifted state is shown in FIG.
As shown in, the weight is in a state of hanging vertically. When the crane hook (not shown) is sequentially lowered from above the thick steel plate 13a 2 , the lower end of the support member 4 first comes into contact with the thick steel plate 13a 2 as shown in FIG. 3 (b). In this state, the descent of the hacker 1 is stopped, and then the hacker 1 rotates about the shaft 5 as a fulcrum as shown in FIG. 3 (c). Complete departure from 13a 1 .

に強度上の面からも有利である。As described above, the hacker 1 of the present invention has the through hole 3 formed in the bent portion of the upper arm portion 2a and the lower arm portion 2b, and the support member 4 is supported by the support member 4 via the shaft 5 inserted and held in the through hole 3. The support member 4 is characterized by being swingably suspended.
With the above-mentioned function, even if the object 13 to be lifted is a heavy object, the locking claw 2 can be efficiently separated from the object 13 to be lifted. Thus, the portion where the through-hole 3 is formed has the shaft 5 supported by the support member 4 as a fulcrum of rotation for hacker 1
However, it may be set at a position where the weight of the object to be lifted 13 allows smooth rotation. For example, in the case of a dogleg bent like the embodiment of FIG. 2, the bent portion is suitable. Further, the support member 4 is limited to the embodiment shown in FIG. 2 as long as it can stably support the hacker 1 with its lower end grounded in the setting scene as shown in FIG. 3 (b). Not a thing. For example, as shown in FIG. 4, the cross-sectional shape is L
Even the support member 40 having a molded structure has no bearing. However, according to the experience of the present inventors, it is advantageous to sandwich the hacker 1 from both sides for more stable support and also in terms of strength.
