Description

[Detailed Description of the Invention] The present invention relates to a hanging fixture for a crane that can transport objects over a relatively short distance while the crane is stopped in a factory.

In order to move an object suspended from a crane hook using a crane such as an overhead traveling crane, even if the distance to be moved is short, the crane body must be operated to move the crane hook.
The operation of the crane is troublesome, wastes time and power, and requires considerable skill to operate the crane so that the object to be transported is accurately moved to a desired position.

The present invention relates to a hanging fixture for a crane completed in order to solve the above-mentioned problems, and the illustrated embodiment will be described in detail below.

1 has a locking fitting 2 such as a ring for hanging a crane hook on the upper end, and a balance arm 3 with a balance weight 3' is stretched on one side of the lower end, so that the whole is L-shaped. The suspension main body 1 has a slide rail 7 on the rear side of its lower part.
is extended in the opposite direction to the balance arm 3 so as to be able to pivot vertically with a connecting end formed at one end thereof, and extends in the opposite direction to the slide rail 7 from the rear side of the upper part. A balance arm 5 is stretched with a circular connecting piece 6 formed at one end thereof so as to be able to pivot in the vertical direction. The balance arm 5 and the slide rail 7 are connected to the free end of the slide rail 7 by a connecting rod 10 whose both ends are pivotally connected to the connecting piece 6 of the balance arm 5 with pins. Further, a hook 9 is provided on the slide rail 7 so as to be slidable via rollers 8, while a balance weight 4 is attached to the balance arm 5, which can be slid or replaced to balance the fluctuating load applied to the hook 9. It is being Note that 11 in the figure indicates a turnbuckle that allows the length of the connecting rod 10 to be adjusted.

With this structure, the locking metal fitting 2 provided at the upper end of the hanging metal main body 1 is hung on a crane foot such as an overhead crane, and the object to be transported W is hung on the hook 9 of the slide rail 7, and then the crane When the lift is raised, the main body 1 of the hanging fixture 1 will be lifted up while maintaining an almost vertical state as shown in Fig. 1 due to the action of the balance arm 3 with the balance weight 3', as shown in the figure. Nifuku 9
is near the base of the slide rail 7, the load applied to the tip of the slide rail 7 is relatively small, so the balance arm 5 is connected via the connecting rod 10.
The moment that tries to rotate it counterclockwise is also small, and the balance weight 4 maintains its balance at a position lower than horizontal as shown in the figure.
Therefore, since the slide rail 7 is maintained in a substantially horizontal state, when the object W to be transported is pushed along the slide rail 7, the rollers 8 at the base of the hook 9 roll to easily move the object W to the desired position. can be moved to the position of Thus, when the transported object W moves toward the tip of the slide rail 7, the load applied to the tip of the slide rail 7 increases, so the slide rail 7 rotates the balance arm 5 counterclockwise via the connecting rod 10. , the balance weight 4 is raised to maintain balance at the position shown in FIG. In this way, when the transported object W is transferred to the tip side of the slide rail 7, the slide rail 7 will swing downward to some extent with respect to the hanging fitting main body 1, and the hanging fitting main body 1 will also rotate counterclockwise. As the moment increases, the slide rail 7 side tends to tilt downward, but in this case, as mentioned above, the balance weight 4 rises to near the horizontal position as shown in Fig. 2. The rotational moment in the clockwise direction also increases, causing the hanging fixture main body 1 to be tilted so that the slide rail 7 side faces upward. Therefore, the downward swinging of the slide rail 7 due to the movement of the transported object W is canceled by the inclination of the hanging fixture main body 1 due to the rise of the balance weight 4, and the slide rail 7
As shown in FIG. 2, it is also maintained in a substantially horizontal state. In this way, the slide rail 7 always maintains a horizontal state even when the transported object W is moved, so the transported object W can be easily moved to an arbitrary position along the slide rail 7, and the movement is carried out using a crane. The object W to be transported can be removed from the hook 9 by lowering the pick. Note that in a factory, the weight of the object W to be moved is often known in advance, and the balance weight 3' and balance weight 4 are set to appropriate weights accordingly. However, when the turnbuckle 11 is used, the angle of the balance arm 5 can be changed by rotating the turnbuckle 11, so adjustment by rotating the turnbuckle 11 is also possible, which is more convenient.

As is clear from the description of the embodiments described above, the present invention includes a slide rail provided with a slidable hook attached to the lower part of the main body of the hanging fitting suspended from the crane hook so as to be pivotable. Since the object to be transported can be hung and moved on the slide rail, there is no need to run an overhead crane or the like to move the object to a slightly distant point, and it is easy to operate. Since it is moved manually, it can be moved accurately to a desired position even by an unskilled person. Moreover, the tip of the slide rail is connected to the front end of the balance arm via a connecting rod, and a balance weight is attached to the rear end of the balance arm to balance the fluctuating load generated on the tip of the slide rail due to the movement of the transported object. Because the object is moved along the slide rail, the slide rail is always maintained in a nearly horizontal state, and the object can be moved extremely smoothly without the risk of the object moving on its own. It has the advantage of being able to be used in a variety of ways, and is of great practical value as it solves the problems of the existing crane hanging fittings of this type.
