DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an apparatus for transporting molten metal or the like for distributing molten metal discharged from a melting furnace to a hand furnace of a casting machine.

[0002]

2. Description of the Related Art Conventionally, as a method of distributing molten metal discharged from a melting furnace to a hand furnace of each casting machine, for example, a method using a reach forklift 51 as shown in FIG. 9 is generally used. The reach forklift 51 includes a mast 52 movable in the front-rear direction of the vehicle body and a fork 53 movable up and down with respect to the mast 52. The angle of the fork 53 can be changed. The hot water distribution pan 54 is placed on the top and can be fixed. Then, the molten metal discharged from the melting furnace is placed in a hot water distribution pan 5.
4, the reach forklift 51 runs to the hand furnace and transfers the molten metal in the hot pot 54 to the hand furnace.

[0003]

However, the method using the reach forklift 51 as described above is convenient for moving objects, but is not suitable for transferring the molten metal in the hot pot 54. . That is, for example, even if the angle of the fork 53 is changed and the hot water pot 54 is tilted, the angle is limited and it is not possible to transfer all the molten metal inside. I needed to replace it. For this reason, there has been a demand for a transporting / supplying device for molten metal or the like that can transport a hot-water distribution pan 54 that has received molten metal discharged from a melting furnace to a hand-held furnace and easily transfer the internal molten metal to the hand-held furnace.

An embodiment of the present invention will be described with reference to the accompanying drawings. Here, FIG. 1 is a plan view of the first embodiment of the present apparatus, and FIG. 2 is a side view thereof (a chain line is an operation diagram showing the operation of the hot water distribution pot). As shown in FIGS. 1 and 2, a transport apparatus 1 for molten metal or the like according to a first embodiment is configured as a dedicated vehicle for distributing molten metal discharged from a melting furnace to a hand furnace of a casting machine. And a hot water distribution pan 3 fixedly attached to the traveling gantry 2. The traveling gantry 2 is configured as a self-propelled electric vehicle (battery car), and includes a steering wheel 4.

[0007] The traveling gantry 2 is provided with a slide guide 6 which can be moved up and down by a drive source (not shown) along, for example, a lift guide 5. Pan rest 7 slidable by source
Is provided. The hot water distribution pan 3 is placed on the pan receiving stand 7 and brackets 7a (only one is shown in the figure) provided on the left and right sides of the pan receiving stand 7 with the hot distribution pan 3 interposed therebetween, respectively. The proximal ends of the cylinder units 8 are pivotally connected, and the distal ends of these reversing cylinder units 8 are connected to pivotal joints 3 a on both side surfaces of the hot water dispenser 3. Also,
A rotating shaft 10 is mounted near the spout t of the hot water distribution pan 3, and both ends of the rotating shaft 10 are pivotally supported by bearings 11, 11 fixed to the pan receiving stand 7.

[0008] A partition wall 12 is provided between the handle 4 and the hot pot 3 to block the transmission of heat, and a worker in a steering room can visually recognize the hot pot 3 above the bulkhead 12. The heat-insulating glass 13 is fitted so as to be able to perform. A hydraulic power unit 14 for driving each drive source and the like, a hydraulic operation panel 1 are provided around the handle 4.
5. An operation panel 16 and the like are provided.

The operation of the apparatus 1 for transporting and feeding molten metal and the like configured as described above will be described. When the molten metal discharged from the melting furnace is supplied to the hot water distribution pan 3, the operator moves the traveling gantry 2 to move it near the hand furnace 17 shown in FIG. Then, after the pan receiving stand 7 is moved forward along the slide guide 6, it is raised along the lift guide 5, and the hot water distribution pan 3 is moved.
Is positioned above the hand furnace 17. When the reversing cylinder unit 8 is extended,
Is rotated around the rotation axis 10 and the molten metal therein is poured into the hand furnace 17.

[0010] Such an operation is performed by the operator through the operation panel 16 or the like while checking the hydraulic operation panel 15 or the like. However, the operation of transferring the molten metal to the hand furnace 17 can be performed continuously. It is convenient because it can be done. Moreover, since the rotating shaft 10 of the hot-water supply pan 3 is provided near the spout t, it is easy to determine the location where the molten metal flows into the hand furnace 17, and the setting of the pouring position is simple and accurate. Is possible.

By the way, in the case of the first embodiment as described above, since the hot water distribution pan 3 is fixedly mounted on the traveling gantry 2, for example, the molten metal discharged from the melting furnace is directly received by the hot water distribution pan 3. However, there may be a situation where the traveling gantry 2 cannot be moved to the tapping part due to space restrictions. In this case, it is necessary to temporarily transfer the molten metal discharged from the melting furnace to a hot water distribution pan 3 after receiving the molten metal in a ladle or the like. Therefore, FIGS. 3 to 8 show a second embodiment in which the above-mentioned problem is improved by making the hot water pot 3 detachable. Here, FIG. 3 is an explanatory view showing an injection state by the device of the second embodiment, FIG. 4 is a perspective view of the attachment, FIG. 5 is an operation view of the attachment in a side view, and FIG. 6 is a front view of the attachment.

As shown in FIG. 3, the apparatus for transporting and supplying molten metal according to the second embodiment includes a traveling platform 21 comprising a modified forklift truck 22 and an attachment 23, and a hot water distribution pan 24 is detachably attached to the attachment 23. I have. The remodeled forklift vehicle 22 remodels a part of an electrically driven forklift to use its lift function, and the lift function allows the attachment 23 to move up and down.

The attachment 23 is shown in FIGS.
As shown in the figure, a base 25 placed and fixed on the forklift remodeled vehicle 22, a pair of right and left columns 26, 26 disposed on both sides of the base 25, and the columns 26, 26
A pair of left and right undulating plates 27, 27 pivotally mounted on rotating shafts 29, 29 at the upper end of the pan, and a pan support 28 fixed to the other end side of the undulating plates 27, 27 are provided. The reversing cylinder units 30, 30 for raising and lowering the undulating plates 27, 27 are connected between the base 25.

Guide rails 31, 31 having a U-shaped cross section are fixed to both sides of the base 25, and the guide rails 31, 31 guide the movement of the columns 26, 26 in the front-rear direction. I have to. That is, rollers 32,... As shown in FIG. 5 are attached to the outer surfaces of the base ends of the columns 26, 26, and these rollers 32,. For example, the base ends of the two columns 26, 26 are connected to each other by a connecting member (not shown).
3 (FIG. 5) are provided. Therefore, when the slide cylinder unit 33 expands and contracts, the columns 26 move forward and backward with respect to the base 25.

The pan receiving tray 28 is placed with a frame 34 for supporting the lower surface of the hot water distribution pan 24, and a holding plate 35 for holding the peripheral side of the lower end side of the hot water distribution pan 24 except the front surface. A lock portion 36 for locking the hot water distribution pan 24 to the frame portion 34 is provided. A pair of left and right fork grooves 34a, 34a, into which a fork can be inserted when the hot water distribution pan 24 is placed by a forklift, are formed in the frame portion 34 in the front-rear direction.

The lock portion 36 is provided at the center of the front surface of the frame portion 34. And this lock part 36

When the hot water distribution pan 24 is positioned and fixed on the frame body portion 34, as shown in FIG. 5, the pouring port t of the hot water distribution pan 24 is positioned near the rotating shafts 29, 29. I have. The reversing cylinder unit 30 and the slide cylinder unit 33 are operated by hydraulic pressure.

In the above-described apparatus for transporting molten metal or the like, the modified forklift vehicle 22 and the attachment 23 are integrally formed, and the hot water distribution pan 24 is detachable. Therefore, for example, if the hot water distribution pan 24 is placed on a small forklift and faces the tapping section of the melting furnace, the molten metal to be discharged can be directly received by the hot water distribution pan 24. And
In order to transfer the hot water pot 24 onto the attachment 23, the fork of a forklift is inserted into the fork groove 34a of the frame body portion 34, the hot water pot 24 is placed on the frame body portion 34, and then the fork is pulled out. . At this time, the lock 3
6 is a locking groove 24a at the front lower portion of the hot water supply pan 24.
So that it can be inserted into. Then, the twist handle 37 of the lock portion 36 is rotated by 90 degrees so that the locking pieces 40 are undetachably engaged with the locking grooves 24a.

The spout t of the hot-water supply pan 24 is made to face above the hand furnace 17. Then, when the reversing cylinder unit 30 is extended and the undulating plate 27 and the pan support 28 are tilted, the hot water distribution pan 24 is tilted and the molten metal inside is poured into the hand furnace 17.

Incidentally, the positioning and reversing operations of the hot water distribution pan 24 as described above can be performed by two systems. That is, one system is a steering room of a forklift modified vehicle 22 as in the past, and can be performed through a hydraulic steering panel, an operation panel, etc. provided around a handle (not shown). The pendant switch 41 shown in FIG. 1 is used to enable remote control at a position where the spout t of the pouring pot 24 can be visually recognized. And by using such a pendant switch 41,
For example, when transferring to a hand furnace 17 of a different type of casting machine, the operation can be performed while visually confirming the work position, which is more reliable and convenient.

By making the hot water distribution pot 24 detachable from the attachment 23 in this manner, the molten metal discharged from the melting furnace can be supplied to the hand furnace more smoothly.
In the embodiment, the example of the transportation and supply of the molten metal is shown, but it is needless to say that the invention can be used as a transportation and supply device for other liquids, powders, granules and the like.
