Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for transporting a cylindrical object, which is most suitable for always transporting a drum, which is a cylindrical object, stably by a lifting device such as a forklift or a hoist.

[0002]

2. Description of the Related Art Conventionally, when a drum can is lifted and transported by a forklift, both side surfaces of the drum can are sandwiched by movement of left and right clamp arms of a forklift clamping device, and the forklift is lifted only by a burr on an outer peripheral edge of a drum can upper cover. Japanese Patent Application Laid-Open No. 10-12 / 1998 discloses a device in which the engagement of the clamp device with the left and right clamp arms is maintained.
No. 97 is disclosed.

Further, the upper end of the drum can is pinched by the outer pawl of the first lever and the inner pawl of the second lever of the drum lifting device, and the drum is lifted together with the drum lifting device. It is disclosed in Japanese Patent Publication No. Hei 6-20786.

[0004]

SUMMARY OF THE INVENTION However, Japanese Patent Application Laid-Open

Since the outer peripheral edge of the forklift is shallow, the vibration of the forklift during running may cause the drum to fall off the left and right clamp arms and fall.

[0005] In Japanese Utility Model Publication No. 6-20786, the upper end of the drum can is only pressed by the outer pawl of the first lever and the inner pawl of the second lever of the drum lifting device. When the drum can is lifted and transported together with the drum lifting device by a hoist or the like, the outer pawl of the first lever and the inner pawl of the second lever of the drum lifting device are only part of the upper end of the drum can. Only sandwiched,
Due to the vibration during lifting of the drum can by the lifting device, the upper end of the drum can comes off from between the outer pawl of the first lever and the inner pawl of the second lever of the drum lifting tool, and the drum falls from the drum lifting tool. There was a risk of doing it.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to simply attach and fix both ends of a ring-shaped main body, the ring-shaped main body can be easily attached to a cylindrical object, and the cylindrical object can be removed. Provided is a drum carrying tool which is transported in a stable state while being lifted by two forks of a forklift together with a ring-shaped main body through a pair of flanges, and there is no possibility that a cylindrical object falls from the ring-shaped main body due to vibration of the forklift. It is in.

[0007]

SUMMARY OF THE INVENTION A cylindrical object carrying tool according to the present invention has a ring-shaped body whose both ends can be fastened and fixed, and the ring-shaped body is integrally provided with a flange extending outward. It has a configuration characterized by the following.

A notch is formed between the outer periphery of the ring-shaped main body and the flange.

Further, the diameter of the ring-shaped main body can be adjusted so as to match the outer diameter of the cylindrical object.

The handle 12 of the T-shaped wrench 10 is manually rotated in the tightening direction, and the nut 13 of the T-shaped wrench 10 is screwed to the fixing bolt 9 to thereby bend the piece 6a of the ring-shaped main body 2. The gap between the ring-shaped main body 2 and the bent piece 6b gradually narrows, and both ends of the ring-shaped main body 2 are fastened and fixed by the fixing bolt 9 and the nut portion 13 of the T-shaped wrench 10. , The inner peripheral surface of the ring-shaped main body 2 is in close contact with the outer peripheral surface of the drum 15, and the upper edge of the ring-shaped main body 2 is the burr 17 of the outer peripheral edge of the upper lid 16 of the drum 15.
As shown in FIG. 9, the cylindrical object transporting tool 1 is fixedly attached to the drum 15.

Forklift (not shown) for cylindrical object
In the case of lifting and transporting by forklift, first, as shown in FIG. 10, two forks 20a and 20b of a forklift are used.
To the lower side of the flanges 3a, 3b of the cylindrical object carrying tool 1.

Thereafter, when the two forks 20a, 20b of the forklift are moved upward, the two forks 20a, 20b of the forklift abut against the lower surfaces of the flanges 3a, 3b of the cylindrical object carrying tool 1. 10
As shown in the figure, the drum can 15, which is a cylindrical object, is lifted together with the ring-shaped main body 2 via the flanges 3a, 3b while the two forks 20a, 20b of the forklift are moved upward. It is transported in a stable state while being lifted by the forklift together with the object transporting tool 1.

When a cylindrical object is lifted and conveyed by an elevating device (not shown) such as a hoist, first, as shown in FIG. 11, a loop portion 25a formed at one end of a slinging wire 25 is formed. The notches 5a, 5a formed between the outer periphery of the ring-shaped main body 2 of the cylindrical object carrying tool 1 and both ends of one flange 3a are hooked, and
The loop 25b formed at the other end is hooked to the notches 5b formed between the outer periphery of the ring-shaped main body 2 and both ends of the other flange 3b, and the center of the wire 25 is hooked to the hook 26 of the lifting device. Hook.

Thereafter, when the hook 26 of the elevating device is raised, the wire 25 moves upward while the hook 26 of the elevating device is raised, and as shown in FIG.

[0029]

As described above, according to the cylindrical object carrying tool of the present invention, the ring-shaped main body is fitted to the cylindrical object, and both ends of the ring-shaped main body are fastened and fixed. Since the inner peripheral surface of the cylindrical body is in close contact with the outer peripheral surface of the cylindrical object,
Since the ring-shaped body can be easily attached to the cylindrical body, and the pair of flanges project outward from the ring-shaped body, the cylindrical body is forked with the ring-shaped body via the pair of flanges. The forklift can be transported in a stable state while being lifted by the two forks, and the upper edge of the ring-shaped body is securely engaged with the burrs on the outer peripheral edge at the upper end of the cylindrical object. There is no danger of falling from the ring-shaped main body due to the vibration of.

Further, by merely hooking the wire of the elevating device on the notch formed between the outer periphery of the ring-shaped main body and the flange, the cylindrical object is lifted by the wire of the elevating device together with the ring-shaped main body via the flange. It can be transported in a stable state as it is, the wire of the lifting device does not come off from the notch between the outer periphery of the ring-shaped body and the flange, and there is no possibility that the cylindrical object falls from the wire of the lifting device.

Further, since the ring-shaped main body has elasticity,
The diameter of the ring-shaped body can be adjusted to match the outer diameter of the cylindrical object, and the inner peripheral surface of the ring-shaped body is securely adhered to the outer peripheral surface of the cylindrical object. Even when the burrs on the outer peripheral edge have no margin, the transportation can be always performed in a stable state.
