Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molten metal conveying device for conveying molten metal from a melting furnace to a holding furnace.

[0002]

2. Description of the Related Art Since a large amount of cast products are produced in the manufacture of automobiles, in a foundry, metal is melted in several melting furnaces, and the molten metal is received from the melting furnaces in a receiving container suspended by an overhead crane. , The crane transfers the hot water container to the holding furnace and tilts the hot water container to pour the molten metal into the holding furnace from the pouring port.

[0003]

However, since the crane is used for raising and lowering or tilting the hot water container, it requires skill in operation and the work efficiency of molten metal transfer is not good.

Further, in the vicinity of the melting facility of the foundry, although the environment is bad because smoke is generated by pouring molten metal and dust is scattered, the hot water container is handled by a crane in a bad environment. There is the problem of having to do work. That is, because the work is done with a crane,
Even if a dust hood is to be installed near the melting and holding furnace equipment, the elevating body such as the wire rope of the crane will obstruct the dust hood and the dust hood will interfere with the crane operator's view, and Cannot be provided.

Therefore, the present invention is to provide a molten metal transporting apparatus which is capable of transporting molten metal from a melting furnace to a holding furnace without using a crane and which can improve the environment.

[0006]

In a molten metal carrier according to the present invention, a swivel base is provided on a traveling carriage that travels between a melting furnace and a holding furnace, and a tiltable hot water container is provided on the swivel base. Provide a lift that has.

A drive device for moving the receiving container forward and backward may be provided on the elevating table, and a dust collecting hood may be provided on or near the molten metal conveying device.

[0008]

FIG. 1 is a schematic diagram of a molten metal carrier according to the present invention, in which a molten metal carrier 1 is arranged between a melting furnace 2 and a holding furnace 3.

The molten metal carrier 1 is moved on a rail 5 by a traveling carriage 4 along a plurality of melting furnaces 2 and a holding furnace 3. A floating prevention body 6 is provided outside the rail 5 so that even if the molten metal transport apparatus 1 tries to float up, there is no safety problem.

The traveling carriage 4 is provided with a swivel base 8 on a swivel seat 7 which swivels 180 degrees by a driving device such as a motor. A counterweight 9 is arranged on the swivel base 8 to balance the molten metal transport apparatus 1.

On the swivel base 8, an elevation table 11 is provided on which the hot water container 10 is detachably mounted in order to move the hot water container 10 up and down.
Is provided with a post 12 for moving up and down, and the lifting platform 8 is supported on the post 12 by, for example, a multi-roller support.

An elevating rack 13 is provided on the post 12, and a gear 15 which is rotated by an elevating drive device 14 provided on the elevating table 11 is engaged with the elevating rack 13.
The rotation of the gear 15 causes the lift 11 to move the post 12 up and down. The post 12 may be supported by a support 16 for reinforcement, and the top of the post 16 is provided with a patrol light 17 that blinks during operation.

The elevator table 11 is provided with a multi-roller bearing 19 for receiving the shaft 18 of the hot-water receiving container 10, and a forward / backward drive device 20 such as a cylinder for moving the multi-roller bearing 19 is further provided. In order to tilt the container 10, a tilting device 21 such as a motor or a cylinder (see FIG.
In the back side). In addition, melting furnace 2
When the pouring position in the holding furnace 3 is fixed, the work can be performed simply by tilting the hot water container 10 without moving it forward and backward.
Need not necessarily be provided. Further, by providing the lid 22 on the hot water container 10, it is possible to prevent the splash of the molten metal at the time of receiving the hot water and the rapid temperature decrease of the molten metal.

An industrial TV camera 23 for monitoring work is provided on the top of the lift 11, and the molten metal carrier is operated by operating the molten metal carrier 1 remotely while monitoring the work with the industrial TV camera 23. .

Further, a dust-collecting hood 24 is provided above the molten-metal conveying device 1 and is connected to the melting-furnace side suction duct 25a and the holding-furnace side suction duct 25, whereby the melting furnace 2, the hot water container 10, and the holding vessel 10 are held. It is also possible to collect smoke and dust generated from the furnace 3 and the like.

Next, the operation of the molten metal carrier will be described.

The molten metal carrier 1 is stopped at a predetermined pouring position of the melting furnace 2, the advancing / retreating drive unit 20 moves the molten metal receiving container 10 forward and backward, and the elevating table 11 causes the molten metal receiving container 10 to move.
Is moved up and down to set the hot water receiving container 10 to the pouring position, and then the melting furnace 2 is tilted to pour hot water into the hot water receiving container 10.

During pouring, the receiving container 10 is lowered according to the inclination of the melting furnace 2 to adjust the pouring height.

When the molten metal in the hot water receiving container 10 reaches a predetermined amount, the melting furnace 2 is rotated to return to the original position, and the elevating table 11 is raised to raise the hot water receiving container 10 to the height of the swiveling position. After that, the swivel base 8 is swung to position the hot water container 10 at the pouring position of the holding furnace 3 (indicated by a chain line in FIG. 1).

Next, the tilting device 21 is used to move the hot water container 10
Is tilted (from the state shown by the alternate long and short dash line in FIG. 1 to the state shown by the solid line), and the molten metal of the hot water container 10 is poured from the pouring port 3a of the holding furnace 3.

When the pouring of a predetermined amount into the holding furnace 3 is completed, the hot water container 10 is returned to its original position by rotating the tilting device 21, and the swivel base 8 is swung to move the hot water container 10 into place. It is placed in front of the melting furnace 2 to finish the pouring work.

The operation of the molten metal carrier is carried out remotely while monitoring the work on an industrial television.

Further, during the work, the dust collecting hood 24 is connected to the suction ducts 25a and 25b to collect dust, thereby preventing generation of smoke and dust.
