Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a belt-shaped belt sling used for lifting a heavy object such as a foam concrete plate with a chalk suspension.

[0002]

[Prior Art]

 The eye-shaped belt sling has a ring-shaped hanging side eye and a belt looping eye on both ends of the belt.After the object to be hung up is circulated, one belt looping eye is hung on the other belt sling end. It is often used for so-called choke suspension, in which a heavy object's body is tightened by the eye on the side of the suspension. When lifting an object with a chalk, especially in the case of an object to be lifted in a narrow space, for example, in the case of a foam concrete plate (product name Hebel) used on the side surface of a building, the plate should be made vertically long and lifted. If you hang it by turning it up and down instead of hanging it with a choke, you cannot remove the belt and it is dangerous. Therefore, the body is hung with a choke, but the belt sling loosens when it is temporarily placed and lifted again. This looseness may cause foam concrete plates to drop.

[0003]

[Problems to be solved by the device]

 The present invention is intended to provide a safe belt sling that does not loosen even if it is temporarily placed on the floor surface or the like with the choke hanging and lifted again as described above.

[0004]

[Means for Solving the Problems]

 The above problem is solved by providing a position regulating means 2 on the belt passing side eye in the choke suspension of the eye-shaped belt sling 1. The position restricting means 2 is a fastener 5 between a portion A near the belt passing side eye 3 and a portion C closer to the belt passing side eye than the belt passing side eye insertion portion B of the belt main body when the choke is suspended by the hanging side eye 4. Or, when suspending the choke with the hanging side eye 4, the belt passing side eye insertion portion B is sandwiched and the belt passing side eye 3 attached to the portion C near the belt passing side eye and the hanging side eye 4 side portion D is stopped. A tool 6 or a hanging tool 7 between the belt-passing-side eye-side portion C and the belt-passing-side eye 3 is preferable.

[0005]

[Action]

 Since the belt sling is provided with the fastener 5 or the position restricting means 2 for the retaining piece 6, even if the object to be lifted is temporarily placed with the choke hanging and then lifted again, the belt passing side eye is the hanging side eye 4. Do not loosen by restricting movement in the direction.

【Example】

 FIG. 1 is a perspective view showing a state in which a foam concrete plate is suspended in a choke suspension state by the belt sling of the present invention, and FIG. 2 is a plan view of the belt sling. The eye-shaped belt sling 1 is formed by weaving a nylon thread into a band shape. There is a ring-shaped hanging side eye 4 and a belt passing side eye 3 at both ends, and after the lifting object 20 is circulated, one belt passing side eye 3 is passed through the other belt sling end hanging side eye 4. There is. As a result, the heavy object is hoisted with the choke hanging.

FIG. 3 shows a first embodiment of the position regulating means. In this example, the position regulating means 2 is the fastener 5. The fastener 5 comprises a hook 5a and a hook receiver 5b attached to the belt body. The hook-shaped hook 5a is provided in the vicinity A of the belt passing side eye 3, whereas the hook receiver 5b is provided so that the position thereof can be adjusted with respect to the adjustment holding belt 10 mounted almost in the middle of the belt body. There is. To fix the mounting position of the hook receiver 5b, the biasing spring 9 is provided coaxially with the mounting shaft of the pressing piece 8 which is rotatably supported by the hook receiving 5b, and is fixed by the pressing portion 8a at all times. Only when the operating portion 8b at the other end is pressed with a finger, it becomes free. The attachment positions A and C of the hook 5a and the hook receiver 5b may be reversed. Alternatively, the fasteners 5 may be attached between the belt passing side eye side portion C and the hanging side eye side portion D of FIG. 1 or 2 to regulate the position of the belt passing side eye side portion C. In this case, the lifting object 20 needs to have a substantially constant size, and serves as a mere stopper 6 as shown in FIG.

A second embodiment of the position regulating means 2 is shown in FIG. The hook-shaped hook 5a is attached to the belt body as in the case of the above embodiment. The hook receiver 5c is an elastic ring difference in this example. This is also used for the stopper 6.

FIG. 5 shows a third embodiment of the position regulating means 2. This position control means 2 is closer to the hanging eye 4 than the belt passing side eye insertion area B when hanging the choke on the hanging side eye 4 Another mode of the stopper 6 provided in a section on the belt main body area D Is. This restricts the movement of the belt passing side eye 3 toward the hanging side eye 4.

FIG. 6 shows a fourth embodiment of the position regulating means 2, which is the simplest. This is a hook 7 between the portion C near the eye on the belt passing side and the eye 3 on the belt passing side. As shown in FIG. 6 (a), the elastic body 7a is moved to the portion C near the eye on the belt passing side of the belt body. The hook 7 is sewn and has a hook 7b at its tip. It suffices to hook the hook 7b on the portion C near the eye on the belt passing side when the choke is suspended. 6 (b), on the contrary, a structure in which a ring-shaped rubber tube is attached as an elastic body 7a to the belt passing side eye 3 and a hanging tool 7c is provided to the belt passing side eye portion C. It is what As a result, the belt sling does not loosen even when the suspended object suspended by the chalk is temporarily placed.

[0011]

[Effect of the device]

 With the present invention, it is possible to ensure the safety when lifting an object by choke using an eye-shaped belt sling. In particular, it is possible to prevent accidents when the foam concrete side plate is attached at the construction site, which greatly contributes to the improvement of construction safety.
