Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a crane apparatus, and more particularly to a crane apparatus for transporting a pouring ladle.

In costly casting equipment that mass-produces centrifugally cast tubes by pouring molten metal into multiple rotary molds, it is common to transport the pouring ladle using an overhead running range. .

Figure 1 shows a conventional overhead traveling crane device for transporting a pouring ladle. 1) It is a club that runs horizontally above, and from this club (3) there is a wire 0
- A hook (5) is suspended via the tube (4). Also, (6) is the operator's cab of the crane device, which is fixed to the traveling part (1).

In this way, the pouring ladle (7) is suspended and conveyed to the mold position by the lage device, and the rotating hash (8) for tilting the ladle is used.
By operating the molten metal, the molten metal is poured into the mold.

However, in such conventional crane equipment,
The driver in the driver's cab (6) and the rotating handle (8)
There is a problem in that the operator of the rotating handle (8) must work in a high temperature and dangerous environment near the ladle (7).

Therefore, the present invention aims to reduce the number of workers required to transport and tilt the ladle, and also to eliminate the need for work in a high-temperature and dangerous environment.

In order to achieve this object, the present invention provides an overhead crane capable of transporting a pouring ladle with a handle drive device that can engage with a rotary handle for tilting the ladle, and a driver's cab of the overhead crane is connected to the overhead crane. The steering wheel drive device is configured so that it can be moved laterally along the running distance of the vehicle, and the handle drive device is configured to be remotely controllable in the driver's cab 1.

Therefore, by transporting the pouring ladle to the pouring position into the mold, moving the operator's cab to a position where the ladle can be easily seen, and remotely controlling the handle drive device from the operator's cab, pouring into the mold becomes possible. , these operations can be performed by the operator of the ceiling clay υ independently, which not only eliminates the need for a person dedicated to operating the rotating hash of the ladle, thereby saving labor, but also making it possible to operate the rotating handle easily. This can be done inside the driver's cab, eliminating the need for work in high-temperature and dangerous environments.

Further, according to the present invention, the overhead crane can move on a running rail, can move on a transverse rail laid above the running rail, and can lift a transported object. and a lift device that is suspended from the rope via a rope, and the uppermost frame member is fixed to the club while the rope is inserted through the inside, and can be extended downward by its own weight. and a telescopic type 199 kite frame that can be contracted by the hook device engaging with the lowermost frame member from below when the hook device is hoisted, and a telescopic kite frame that can be contracted by the hook device engaging the lowermost frame member from below, and the uppermost frame member and the uppermost frame member when the guide frame is contracted. The guide frame may be configured to include a connecting member that connects the lower frame member to each other and anchors the guide frame to the club.

勺ゝ- According to such a configuration, since the lift device A is engaged with the kite frame, the kite frame prevents the pendulum movement of the lift device by the rope when the crane device is moved. As a result, it is possible to prevent the object to be transported from shaking, so that the pouring ladle and the like can be transported safely and reliably. Moreover, since the uppermost frame member and the lowermost frame member are connected to each other when the 13-id frame is contracted, shaking can be prevented even more reliably. Further, when the uppermost hook 6 member and the lowermost frame member are connected, that is, when the hide frame is moored to the club, only the hook device is left in a free state, allowing the crane to be used as a normal overhead traveling crane.

The ladle (7) is transported to the pouring position by moving the ladle (7) and the club handle. Once you arrive at the pouring point, the Fu-tsuku tribe @
(A) is lowered to bring the ladle (7) closer to the i-shape.

If the Noid Frame OI) is locked by Tong+-0◇, lower the Fukuzoku @) after releasing this lock. At the pouring position, the driver's cab θG is moved to a position where the ladle (7) can be easily seen, and the handle drive device is operated to rotate the rotary hash (8) of the ladle (7) to tilt the ladle (7) into the mold. In addition, the mold is made of 0◇
It is preferable to install the ladle (7) at a height that does not allow it to fully extend to prevent the ladle (7) from shaking even when pouring. After pouring the metal into the mold, tilt the ladle (7) back and
Pour into another mold using the same operation as above.

When the ladle (7) is empty, the ladle (7) is transported to a fixed position. During transportation, use the winding drum (c) to wind up the hook device (c), and at the upper limit position, apply the tongs +- (4j) to retract the club. Moor to the (a) side. Further, the handle drive device is separated from the rotating hash paddle (8) as shown by the imaginary line in FIG. 3, and the engagement between the rotating handle (8) and the rotating disk is released. At the stationary position, only the hook device (5) is lowered and the ladle (7) is placed in place, and the hook device (5) is removed from the ladle (7) by an inch-7 movement, and then the hook device (ψ) is removed from the ladle (7). Move the hook device (a) away from the ladle (7) by hoisting the hook or moving the crane device. Thereafter, repeat the above operation.

In the above embodiment, the crane device according to the present invention is used to transport a pouring ladle, but when suspending something other than a ladle as described above, the kite frame must be retracted and attached to the club. By mooring it and leaving only the hook device free, it can also be used as a normal overhead traveling crane.

As described above, according to the present invention, the operator of the crane device can also perform the tilting work, which eliminates the need for a dedicated person for the tilting work, thereby saving labor. Since it can be carried out by remote control, there is no need for high-temperature and dangerous work near the ladle.
