Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is for carrying a load other than a coil by suspending a gate-type coil suspension device dedicated to coil transportation on a crane and hoisting it by this gate-type coil suspension device. The present invention relates to a general-purpose sling that can be used for.

[Conventional technology]

In the steel industry and the like, a coil such as a metal band (hereinafter, simply referred to as a coil) is transported by lifting it by a crane. Usually, the coil is often transported by an overhead traveling crane (hereinafter, simply referred to as an overhead crane) in the building of a factory, so this case will be described below.

Generally, the coil is very heavy, weighing several tons or tens of tons, so there is no danger of the coil falling off during lifting, so it is safe to use a gate-type coil suspension for carrying the coil. It is widely practiced to hoist the equipment with an overhead crane and then hoist and carry the coil.

Hereinafter, with reference to the drawings, the above-mentioned gate type coil suspension device and its usage will be described.

FIG. 8 is a front view of an example of a gate type coil suspension device suspended from an overhead crane, and FIG. 9 shows a main part of the example where the gate type coil suspension device is suspended from an overhead crane of another example. It is a front view.

As shown in FIG. 8, the portal coil suspension device 1 carries the coil S by inserting the claws 3a of the portal coil suspension device 1 into the space formed in the central portion of the coil S from both sides thereof. It is a device. The outline of the configuration is as follows. A substantially L-shaped arm 3 is provided on both sides of an arm holder 2 suspended from a crane, for example, an overhead crane 4 with coil lowering claws 3a consisting of horizontal portions of its lower end facing each other. It is configured so that it can be freely moved toward and away from. Next, the overhead crane 4 will be explained. The crane main body 5 is equipped with wheels 5a and travels on a rail 7 provided on a pillar 6 of a factory building, and the club 8 is equipped with a take-up drum 8a. A sheave 10 is engaged with the lower end of a wire 9 that travels on the rail 5 at right angles to the traveling direction of the crane main body 5 and is unwound and wound by the winding drum 8a. The arm holder 2 is suspended at 11, that is, the portal coil suspension device 1. In addition to the case where there is only one hook 11 as shown in FIG. 8 as shown in FIG. 8, such an overhead crane 4 has another set of winding drums 8a ', It may be provided with a wire 9 ', a sheave 10' and a supplementary hook 11 '.

With such a gate-type coil suspension device 1, the coil S
Other than luggage such as interleaving paper, parts, baling hoop material,
When it becomes necessary to transport the waste container, the waste stored in the container, the tools and the like, various problems occur depending on the type of the overhead crane 4 as described below.

When the overhead crane 4 shown in FIG. 8 is used, the suspended gate-type coil suspension device 1 must be detached each time, and the detachment work and the predetermined storage position of the gate-type coil suspension device 1 must be performed. It takes a lot of man-hours to move and is inefficient.

Further, when the overhead crane 4 shown in FIG. 9 is used, since the auxiliary winding hook 11 'is provided, it is usually not necessary to detach the gate type coil suspension device 1 each time, and the hook 11
(In this case, it is called the main winding hook)
While being suspended, the ceiling crane 4 is hoisted up to the upper limit, and the auxiliary hook 11 'is hoisted down for use. However, even in this case, since the auxiliary winding hook 11 ′ is provided together with the main winding hook 11 in the overhead crane 4,
The area covered by the auxiliary winding hooks 11 'on the floor surface covered by the movement of the space is narrowed, so that a portion that cannot be effectively used occurs inside the building. In addition, during transportation work, the gate-type coil suspension device 1 still hung on the main winding hook 11 may sway and come into contact with the wire 9'for the auxiliary winding hook 11 ', causing a fall accident of the luggage. Further, since the structure related to the auxiliary winding hook 11 'is generally small, when the weight of the load exceeds the rated load of the auxiliary winding hook 11', the main winding hook 11 is connected to the gate coil as in the case of FIG. The hanging device 1 will be detached and used.

Further, the sheave 10 is attached to the upper end of the gate-type coil suspension device 1 without using the hook 11, and the sheave 10 is directly suspended by engaging the wire 9 (not shown) or the overhead crane 4. There is also one (not shown) in which the gate type coil suspension device 1 is attached to the lower end portion of the lance which is held by the lance and has the function of raising and lowering and turning.

[Problems to be solved by the device]

The present invention solves the above-mentioned drawbacks of the prior art, and it is not necessary to attach and detach the gate-type coil suspension device from the ceiling crane when carrying not only the coil but also luggage other than the coil, and moreover, the floor surface in the building is widely covered. It is an object of the present invention to configure a transportation means that is commonly used for transporting loads other than coils so that it can be moved and has good slinging operability or can be operated unmanned.

[Means for solving the problem]

As a result of various studies, the inventors of the present invention have utilized a conventionally used gate-type coil suspension device, which has a claw engaging portion that can be safely suspended and which is itself a hook with good operability. It was clarified that the above-mentioned problem can be solved by using a hanging tool having a.

That is, the suspender according to the present invention is detachably attached by the coil-hanging claw of the gate-type coil suspending device having the above-described structure, and the claw locking portion which can be inserted and hung from the side is provided. A rotary shaft for hook hooking is rotatably mounted horizontally on the lower part of the main structure on both sides, and the hook is rotatably locked to the rotary shaft with its base as a vertical rotary shaft. It is characterized by being.
