DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging device for handling a drum, which can suspend a drum of various dimensions and transport the suspended drum to a predetermined position in a suspended state.

[0002]

2. Description of the Related Art Conventionally, for example, a manufactured electric cable is wound on a dedicated drum, stored in a warehouse, and then shipped together with the drum as required. Such a drum for an electric cable has a wide-diameter flange with an outer diameter of about 2000 mm attached to both end surfaces of a horizontally long body portion around which the cable is wound.

As a method for carrying such a large-sized drum into and out of a warehouse, there are a method using a forklift and a method using an overhead crane. When an overhead crane is used, a dedicated hanging tool attached to a hook of the overhead crane is inserted into a hanging hole of the drum, and then a wire rope is wound by a hoist, and the load is suspended to a predetermined height. The drums are lifted, and the trolleys are traversed while the overhead cranes are traversed while the drums are being transported.

In the transfer using such an overhead crane, it is natural that when the hanging tools are inserted into the hanging holes of a large number of drums stored in a warehouse, the positioning of the hanging holes and the hanging tools must be performed. Must. However, since the posture of the hanging tool suspended from the hook of the overhead crane is unstable, there has been a problem that inserting and removing the hanging tool from the hanging hole requires human labor.

In order to solve this problem, the inventor of the present application has proposed a jig-shape having a flat central portion and downward bent both side portions at both ends of a hanging member main body which can be hooked on a hook of a trolley of an overhead crane. A centering guide is provided, and a hanging arm is provided at an intermediate position between the centering guides, and a suspension arm having a holding pin inserted into a hanging hole is protruded below the centering guide. We have developed a drum handling suspender that automates loading and unloading of the drum by making it movable in the axial direction of the drum by a mechanism mounted on the main unit.

In this drum handling suspender, with the both suspension arms previously moved in a direction away from each other by a drive mechanism, the suspender is placed directly above a desired drum by an overhead crane and lowered. . Thus, at least two points of the centering guide in the form of a rim are brought into contact with the outer peripheral surface of the enlarged flange of the drum, and each hanging hole of the drum can be aligned with the holding pin of the hanging arm. By moving both suspension arms in a direction approaching each other by the mechanism, each holding pin can be inserted into the suspension hole of the drum, and can be lifted and transported by the trolley.

As described above, in the above-described hanging member for drum handling, since the centering guide in the form of a rim is brought into contact with the enlarged-diameter flange at at least two points, the centering guide follows the arc surface of the enlarged-diameter flange. Even when there is a certain error in the stop position of the trolley, the trolley can reliably lift and transport the drum.

[0008]

However, the above-mentioned hanging member for drum handling still has the following problems to be solved. In other words, the centering guide in the form of a jinka is directly in contact with the outer peripheral surface of the expanded flange of the drum,
On the other hand, since the lifting tool main body including the centering guide and the driving mechanism becomes heavy, a considerably large sliding resistance is generated on the sliding surface between the expanded flange of the drum and the centering guide. Therefore, it is also conceivable that only one point of the centering guide in the form of a rim contacts the outer peripheral surface of the enlarged flange of the drum, and the other point does not contact the outer peripheral surface of the enlarged flange of the drum.
In this case, each hanging hole of the drum and the holding pin of the hanging arm cannot be aligned, and it becomes impossible to lift and transport the drum by the trolley.

[0009] Further, when there is a relatively large displacement in the lateral direction at the lowered position of the hanging member for drum handling,
First, the lower end of the suspension arm or the retaining pin protruding inwardly comes into contact with the expanded flange of the drum, and there is also a problem that the lifting tool cannot be lowered to the retaining pin insertion height position so as to wrap the drum. Was.

The present invention has been made in view of the above circumstances, and it is possible to automatically align a hanging pin with a hanging hole at the time of drum handling, and to correct a positional deviation of a hanging tool for drum handling with respect to a drum. An object of the present invention is to provide a hanging tool for drum handling that can realize automation of loading and unloading of a drum.
