JPH06144769A - Bobbin hoisting fixture - Google Patents

Abstract

PURPOSE:To provide a safely usable bobbin hoist fixture which enables locking pieces to easily and simply be locked on a bobbin at its locking section, and prevents the bobbin from simply falling down even if the bobbin is shocked by impacts. CONSTITUTION:The bobbin hoisting fixture is made up of a hoist fitting main body 1 which is wider than a bobbin to be hoisted up by a hoist, a crane and the like, paired locking pieces 11 which are rotatably installed at both the ends of the hoist fitting main body 1 to lock the bobbin to be hoisted up, and of a locking mechanism 19 which allows the paired locking pieces 11 to be rotated in the locking direction or the releasing direction while being linked with the actuation of an open/close lever 25 rotatably set roughly at the center section of the hoist fitting main body 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin suspending device used for moving a bobbin for winding and storing cable electric wires, ropes, steel wires, tubes and the like.

[0002]

2. Description of the Related Art Conventionally, a bobbin hoisting device of this type has a hoisting or hanging crane and a pair of hooks which are rotatably attached to both ends of the hoisting metal and which are locked by their own weight. It is composed of a stop piece and a lever attached to one of the pair of lock pieces to open the one lock piece.

[0003]

In the conventional bobbin lifting device, the lifting metal fitting is lowered from the upper portion of the bobbin until the pair of locking pieces are positioned below the locking portion of the bobbin.
At this time, the lifting metal fitting must be manually moved so that the pair of locking pieces can pass through the locking portion of the bobbin, and the lifting metal fitting is lifted to lock the pair of locking pieces and the bobbin. Since the part is locked by the weight of the pair of locking pieces, there is a drawback that the locking may not be performed reliably.

Further, since the bobbin is used in a narrow space because it is locked to the locking portion of the bobbin by the weight of the pair of locking pieces, it rides on an obstacle and the pair of locking pieces moves onto the bobbin. There is a drawback that the bobbin is easily disengaged from the engaging portion and the bobbin falls easily.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
The pair of locking pieces can be easily and securely locked to the locking section of the bobbin, and even if the bobbin collides with an obstacle during movement, the pair of locking pieces will come off from the locking section of the bobbin. The purpose of the present invention is to provide a bobbin hanger that does not wear.

[0006]

In order to achieve the above object, the present invention provides a lifting metal fitting body having a width larger than that of a bobbin to be lifted by a hoist or a crane, and the lifting metal fitting body. A pair of locking pieces which are rotatably attached to both ends of the lifting bobbin and which lock the lifting bobbin, and the pair of locking pieces are rotated in the locking direction or in the opening direction to approximately the center of the lifting metal fitting body. The bobbin suspender is composed of a locking piece actuating mechanism that rotates in conjunction with the operation of the opening / closing lever that is installed as possible.

[0007]

In the bobbin suspender constructed as described above, the pair of locking pieces can be rotated in the opening direction and the locking direction by the locking piece actuating mechanism by operating the opening / closing lever.
