Description

[0001]
[Industrial applications]
The present invention relates to a tool for lifting a drum can in an upright state.
[0002]
[Prior art]
Conventionally, many tools for lifting a drum can have been proposed. There are two types: a drum can be hung in a laid state, and a drum can be hung in an upright state.Either way, the ears provided at both ends in the axial direction of the drum can, that is, a cylindrical body and a disk-shaped Utilizing the tightened portion provided for coupling with the face plate of the above, the hook is hooked on the tightened portion at the position of the diameter of the drum and suspended therefrom (for example, JP-A-6-127896). .
In addition, when hooking the claw on the winding portion, there is also a device in which the inside and outside of the wound portion are clamped by a claw so as to be lifted at a point on the circumference instead of the diameter position (for example, JP-A-7-228470). .
[0003]
[Problems to be solved by the invention]
However, the conventional drum can hanger is about the same size as a drum, is large, is structurally complicated, and has to be expensive when commercialized.
[0004]
[Means for Solving the Problems]
The above-described problem is caused by providing a holding member for holding the tightened portion of the drum can at both ends of the wire rope, and using a pair of holding links connected by a pivot shaft and an auxiliary link connected to the holding link. A four-bar link is formed, the other end of the auxiliary link is connected to a pivot of a suspension ring locked to a wire rope, the four-bar link is a plate-like link member, and the engaging portion is one of the holding links. And a pressing arm provided on the other holding link for pressing the inside of the tightening portion. This is solved by providing a U-shaped notch that opens in the circumferential direction of the part, and fitting and welding a plate-shaped main claw therein.
[0006]
[Action]
When the wire rope is pulled up from a state in which the holding link forming the holding member is engaged with the winding portion of the drum can, a pair of holding links forming a part of the four-bar link is operated by the tension of the wire rope to form the holding link. The drum arm is lifted while pressing the tightened portion of the drum can with the pushing arm and the supporting arm.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter, an embodiment of the present invention will be described. In FIG. 1, reference numeral 10 denotes a drum can hanging device according to the present invention. The drum can suspender 10 has a steel wire rope 11 that is lifted by a hook f of a crane or a fork of a forklift, and holding members 20, 20 connected to both ends thereof, and the drum 15 is wound by the holding members 20, 20. Lift up with the fastening part 16 in between. Both ends of the wire rope 11 are folded to form a loop 11a, and the wire 11 is connected to the loop 11a through a suspension ring 21, which is an element of the holding member 20.
[0008]
As shown in FIG. 2, the holding member 20 is configured by a pantograph-shaped four-node link having four plate-like links. The plate-like link comprises a pair of sandwiching links 23, 24 connected by a pivot shaft 22, and auxiliary links 26, 26 connected to them by pins 25, 25. Are rotatably connected by a pivot 27.
[0009]
The holding links 23 and 24 and the two auxiliary links 26 and 26 forming the holding member 20 are made of strip-shaped plate-like link members, and the holding links 23 and 24 are provided with a pin 25 from the pivot shaft 22. An engaging portion composed of two arms provided so as to protrude in a direction opposite to the above is formed. These arms are a support arm 23a for supporting the outside of the winding portion 16 of the drum 15 from below and a pushing arm 24a for pressing the inside of the winding portion 16. As is well known, the winding portion 16 of the drum can 15 is formed by winding the body portion 15a and the face plate portion 15b outward at their edges and then pressing them from inside and outside to form a flange so that they are watertight. I'm wearing
[0010]
As shown in FIGS. 3 and 4, the support arm 23a is provided with a U-shaped notch that opens toward the inside of the holding link 23, and a plate-shaped main claw 23b is fitted into the notch, and the main claw 23b is inserted. It is greatly extended in the direction of the tightening portion 16 and the direction in which the push arm 24a is located, and is disposed so as to be long in the circumferential direction and welded. Therefore, although the support arm 23a is made of a plate material, it can stably support the drum.
[0011]
Next, a method of using the drum can hanging device 10 will be described. First, the center portion of the wire rope 11 is hung on a hook of a forklift or a hook of a crane to lift the drum can hanging tool 10 and move it directly above the drum 15 placed on the ground. Then, the holding member 20 is suspended at approximately two positions in the diameter direction from the winding portion 16 of the drum 15, and the holding member 20 is opened in this state, so that the support arm 23 a is on the outside of the drum 15 and the pushing arm 24 a is on the inside. And hang it. After hooking, pull up the forklift claw or crane hook.
[0012]
As a result, the suspension ring 21 and the pivot 27 supported by the suspension ring 21 rise. However, since the support arm 23a forming the lower end portion of the holding link 23 is hooked on the winding portion 16, the pushing arm 24 a is attached to the winding portion 16. By pressing the inner surface, the engagement between the support arm 23a and the tightening portion 16 is ensured, and the drum can 15 is lifted from the place where the wire rope 11 is fully extended.
[0013]
【The invention's effect】
As described above, according to the present invention, since the drum can hanging device is constituted by the wire rope and the holding members attached to both ends thereof, the structure is simple, and handling such as lifting and storage when not in use is easy. is there. In addition, although the main part of the holding member is made of plate material and is lightweight, it is connected to the wire rope using a suspension ring, so both are strongly connected and high rigidity is obtained. It is. Further, the holding member uses a holding link as a plate-shaped link member, and the main claw of the support arm that engages with the tightening portion of the drum can is also made of a plate material. Since it is fitted and welded to the notch provided in the above, high strength can be obtained with a simple configuration.
And so on.
