  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments shown in the accompanying drawings, and includes all embodiments that satisfy the requirements described in the claims. .

As shown in FIG. 1, for example, the lifting tool 1 is wound so as to be along the side surface of the transported object T, so that both end portions thereof are opposed along the side surface, and both end portions of the winding portion 2 are wound. A plurality of suspension belt hanging portions 3 provided on each of the suspension belts, and a suspension belt which is attached to the winding portion 2 or the suspension belt hanging portion 3 and slidably engageable with all or some of the suspension belt hanging portions 3 4 and pulling the suspension belt 4 engaged with the suspension belt hook portions 3 at both ends in a state where the winding portion 2 is wound around the transported article T, whereby the suspension belt 4 is wound around the winding portion 2. At the same time, the transported object T is lifted while being tightened.

Here, the side surface of the transported object T refers to the side surface of the transported object immediately before lifting. Moreover, that both ends are opposed along the side surface means that both ends of the winding part 2 wound around most of the side surface of the transported object T are positioned so as to abut on the side surface of the transported object. Specifically, both ends of the winding part wound around about a half circumference of the side surface of the transported object T and the suspension belt hanging parts at both ends of the winding part wound substantially over the entire circumference are opposed to each other while overlapping each other. Including the state. Moreover, although the winding part 2 and the suspension belt 4 are comprised as what sewed synthetic resin fiber, it is not restricted to this, Even if it is a belt member of other materials, for example, a rope, a chain, etc. Any long member that can transmit at least a tensile force may be used.

The winding part 2 includes three long belts 6a, 6a, 6b having substantially the same length provided in parallel, and six connecting members 7a, 7b,. The long belts 6a, 6a and 6b are provided with suspension belt hooks 3, 3 and 3 provided at both ends. Thereby, the winding part 2 is formed as what has a substantially rectangular external shape, and is comprised as a shape which is easy to wind around the conveyed product T. FIG. In addition, since the ring is attached to both ends of the long belt 6 to form a hanging belt hanging portion, the tensile force by the hanging belt 4 is applied in the longitudinal direction of the long belt 6 and it is easy to ensure the necessary strength for the lifting tool 1. It is highly durable.
Further, since the winding portion 2 is configured by combining the long belt 6 and the coupling body 7 in a lattice shape, the winding portion 2 has sufficient strength with a simple configuration with a small number of members and can cover a wide range. .

The vertical and horizontal dimensions of the winding unit 2 may be any dimension that can be wound around the side surface of the object to be transported T. However, in the illustrated example, the dimension in the longitudinal direction (lateral direction) is the object to be transported. It is assumed that most of the side surface of the flexible container (about three to three and half surfaces) can be covered, and the dimension in the short direction (longitudinal direction) is slightly shorter than the height of the flexible container. Thus, after the winding part 2 is wound around the transported object T, the suspension belt hooks 3, 3,... Provided at both ends of the winding part 2 are pulled up, and the transporting part T is sufficiently secured by the winding part 2. And can be securely held.
Here, the winding part 2 may further be provided with a suspension belt hanging part for adjustment inside the suspension belt hanging part 3 provided at both ends. Even a transported object having a shorter outer circumference than the winding part 2 can be lifted in a sufficiently tightened state by pulling the suspension belt 4 engaged with the suspension belt hanging part for adjustment.

  Three suspension belt hooks 3, 3,... Are provided on both ends of the winding part 2 in the longitudinal direction, three in total. The suspension belt hooking portion 3 is formed by attaching a metal ring as a separate member to the end of the long belt 6 of the winding portion 2, and can withstand a heavy load caused by the lifting work. It is comprised as what has sufficient intensity | strength. Moreover, since it is composed of a metal ring, the frictional resistance is low and the frictional force applied to the suspension belt 4 is small, so that the wear of the suspension belt 4 during lifting work is reduced and the durability of the product is improved. It has become something that can be done.

The suspension belt 4 is constituted by a belt member, and one end is attached to the lifting tool 1 and the other end is attached to a heavy machine such as a crane truck. For example, two suspension belts 4 are used as shown in the figure, and one end of each suspension belt 4 is fixed to two suspension belt hanging portions 3 and 3 which are at the lowest position in the lifting operation, and these belts are opposite to each other. The belt can be pulled up by being inserted into the belt hook 3 while being engaged with the hook 3.
Here, the suspension belt 4 is not limited to a belt member, and may be a long member that can transmit a tensile force such as a rope or a chain. Moreover, it is good also as what prevents the excessive clamp | tightening to the conveyed product T during a lifting operation | work by providing the switching part and another member which become a stopper in the middle of the suspension belt 4. FIG. Further, the suspension belt 4 may be attached to the winding portion 2 as shown in the figure, but it may be attached to the suspension belt hook portion 3, but may be fixed to the winding portion 2 by sewing, separate metal fittings, or the like. The extended portion of the long belt 6 constituting the portion 2 may be configured as a suspension belt 4, and the suspension belt 4 is configured as a single piece. It is good also as what passes through the suspension belt hook part 3 and raises these both ends by a heavy machine.

In addition to the suspension belt 4, the winding portion 2 is provided with an auxiliary belt 5 for assisting lifting by the suspension belt 4. Since one end of the auxiliary belt 5 is attached to the central portion of the winding portion 2, the auxiliary belt 5 is positioned on the opposite side of the suspension belt 4 in the lifting operation. In addition, the auxiliary belt 5 is attached to an intermediate long belt 6a constituting the winding portion 2 so that the winding portion 2 from the transported object T by lifting the auxiliary belt 5 upward is difficult to come off. It is configured.
Although the auxiliary belt 5 is configured by sewing the same synthetic resin fiber as that of the winding portion 2 and the suspension belt 4, the manufacturing cost is reduced. However, the invention is not limited to this, and belt members of other materials are used. Or a rope, a chain, etc. may be sufficient, for example, and what is necessary is just a long member which can transmit a tensile force at least. Further, the auxiliary belt 5 may be detachably attached, or may be capable of changing the length.

  The long belt 6 and the connecting body 7 constituting the winding part 2 will be described.

  In the winding part 2, three long belts 6, 6 and 6 having substantially the same dimensions are arranged in parallel. Since these are belts made of synthetic fibers that do not stretch or are difficult to stretch, the force transmitted from the suspension belt 4 can be directly used for tightening and pulling the transported goods T. The long belt 6b, which is the lowest position in the lifting operation, is configured to be narrower than the other long belts 6a. For this reason, it is easy to bite into the transported object T when fastening the transported object T in the lifting operation, and the transported object T can be prevented from falling off during the lifting operation.

  The winding part 2 is provided with a connecting body 7 that connects the three long belts 6, 6, and 6 at intervals. In the middle excluding both ends of the winding part 2, a wide connecting body 7 a is provided to connect the respective long belts 6, and to securely hold the transported object in the lifted state, and to both ends of the winding part 2. In the part, by connecting with the narrow connecting body 7b, the user can easily check the end of the wound body 2, thereby improving workability and facilitating handling.

Since the long belt 6 and the connecting body 7 are combined in a lattice pattern in the winding part 2, a gap 8 is formed between them. These gaps 8,... Are formed in such a manner that when the transported object T is tightened by the hanger 1, the wound part 2 bites into the transported object T, so that the transported object T protrudes outward. Will be held more reliably.

Hereinafter, the lifting method and the transporting method of the transported article T accommodated in a general flexible container bag using the lifting tool 1 will be described with reference to FIGS.

  First, as shown in FIG. 2, the lifting tool 1 is positioned along the side surface of the transported object T. At this time, if the long belt 6a at the uppermost position of the lifting tool 1 is in the vicinity of the upper end of the transported object T, the long belt 6a may come out above the transported object T during tightening. The height of the lifting tool 1 is set so that the long belt 6a is located slightly below the upper end of the transported object T.

  Next, as shown in FIG. 3, in the state where the lifting tool 1 is arranged so as to cover the side surface of the transported object T, one suspension belt 4 with one end tied to the suspension belt hanging portion 3 at the lowest position is attached. , It is inserted into the suspension belt hanging portion 3 located at the same height on the opposite side, and then engaged with the suspension belt hanging portion 3 so as to be substantially in the shape of a letter by being inserted on one step on the opposite side, Furthermore, it is made to pass through one step on the opposite side. Thereafter, the other suspension belt is similarly engaged with the suspension belt hook 3. At this time, since the suspension belt hook portion 3 is formed of a ring-shaped metal fitting, it is possible to smoothly insert the suspension belt 3 without applying excessive frictional force to the suspension belt 3.

  Finally, the ends of the suspension belt 4 and the auxiliary belt 5 are hooked on the hooks F of the crane truck and pulled up substantially directly above. Then, first, the slack of the two suspension belts 4 and 4 is eliminated, and these are pulled upward, so that each of the suspension belt hook portions 3 provided at both ends of the winding portion 2 is hooked on the opposite suspension belt. Pulled to approach part 3. Thereby, as shown in FIG. 5, the transported object T is fastened by the winding part 2. Here, in the gap 8 of the winding part 2, since a part of the transported article T protrudes outward, it can be prevented from falling off.

  As shown in FIG. 6, when the lifting of the transported goods T by the suspension belt 4 starts, the side that is lifted by the suspension belt 4 first floats upward. At this time, the lifting force by the auxiliary belt 5 starts to act on the transported object T even on the opposite side. By further pulling up the hook F as it is, the transported object T is lifted in the air in an obliquely inclined posture. By being lifted in such a tilted posture, it is possible to maintain sufficient biting of the winding portion 2 into the transported object T, and it is difficult to come off compared to a case where it is lifted directly above, and safely transported object T Can be lifted. Moreover, in the lifting by this inclined posture, the auxiliary belt 5 engages with the upper end of the transported article T, and therefore, the excessive tilting of the transported article T can be prevented.

  As described above, the lifting tool 1 is such that the greater the weight of the transported object T, the greater the tightening force of the transported object T by the winding portion 2, so that regardless of the weight of the transported object T, It can be lifted with the transported object T reliably and safely.

In addition, in this embodiment, although demonstrated as what lifts and conveys the conveyed product accommodated in the rectangular parallelepiped flexible container bag, it is not restricted to this, The conveyed item accommodated in the general cylindrical flexible container bag, You may lift and convey the conveyed product which is not accommodated in a bag. Moreover, the attachment of the suspension belt to the winding portion is not limited to that performed via the suspension belt hanging portion, and may be directly attached to the winding portion, or provided integrally with the winding portion. It may be. Further, the suspension belt is engaged with the suspension belt hanging portion by engaging the two suspension belts with the suspension belt hanging portion in a substantially square shape, thereby simplifying the structure and reducing the manufacturing cost. However, the present invention is not limited to this, and any configuration may be used as long as the force acts in the direction in which both ends of the winding portion approach each other by pulling the suspension belt upward. It is good also as what reduced the number of parts as what was made to engage with the suspension belt hook part which opposed this suspension belt alternately.
