Abstract

PURPOSE:To easily manufacture a pouring apparatus at a low cost by integrally joining an arm for hanging and a holding parts separately formed with a reinforced plate. CONSTITUTION:Rotated supporting shafts 1a, 1b in a ladle T are supported not only at two positions of one part of holding parts 2a, 2b, but at three positions including supporting part 6. By this construction, it can be prevented for long period that gap caused by wear at between the rotated supporting shafts 1a, 1b and the arm holding parts 2a, 2b develops, compared with a casting apparatus for molten metal composed of the ordinary two positions as the supporting construction. Further, in the case the gap caused by the wear at between the rotated supporting shafts 1a, 1b and the arm holding parts 2a, 2b develops with tilting operation of the ladle T, as the countermeasure to this, the reinforced plate 4a is integrally joined to the holding part 2a and a laying plate 5 is connectively formed to the reinforced plate 4a and the tilting mechanism 7 is arranged on the laying plate 5. Then, the rotated supporting shaft 1a in the ladle T is supported with the supporting part 6. By this method, it is prevented that large load acts on the tilting mechanism 7 and this is used at good condition for long period.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a molten metal casting apparatus, and more particularly to a suspended type molten metal casting apparatus that can be satisfactorily used over a long period of time.

<Prior Art> Conventionally, as a hanging type molten metal casting device, as shown in Fig. 6, a pivot shaft (i
It has a hole through which the ladle (T) is inserted.
') hanging and holding the pivot shaft holding part (102a) (10
2b) is forged integrally with the hanging arm <103a) (103b), and one of the pivot shafts (101
A ladle tilting mechanism (1G4) consisting of a transmission, a handle, etc. is provided on the extension of a), and the ladle is tilted at an appropriate position,
There are known molds that allow molten metal to be poured into a mold.

<Problems to be Solved by the Invention> However, the conventional molten metal casting device described above has a worm screw (104b) that transmits the rotational operation of the handle (104a) to a worm wheel (104b) fixedly attached to a pivot shaft (tola). 104c) was attached to the hanging arm (103a), it had the following disadvantages.

In other words, if a gap occurs due to wear between the pivot shaft of the ladle and the arm holding part, when performing a lifting operation with the suspension arm, the pivot will be removed by the gap due to wear compared to when lifting with the suspension arm (103a). Since the timing of lifting the support shaft will be delayed a little, the worm screw (104c) side attached to the hanging arm (103a) will be lifted first.
The attachment to the pivot shaft (Iota) results in poor engagement with the worm wheel (104b), which has disadvantages such as the inability to tilt the ladle using the handle (104a).

Therefore, the applicant first formed the hanging arm and the holding part as separate members and joined them together with a reinforcing plate.
An application was filed for a device in which a mounting plate was formed in series with this reinforcing plate, and a transmission was mounted on the mounting plate (Japanese Patent Application No. 83-13).
11751).

In the case where the transmission is mounted on the above-mentioned mounting plate, any deviation in the timing of lifting due to the gap between the above-mentioned pivot shaft and the arm holding part will not directly affect the transmission, and the transmission will be in good condition. However, when it was suspended using a crane or the like, a large load was placed on the transmission, which could easily cause damage, and the transmission had to be repaired repeatedly.

This invention relates to improvements to these conventional products,
The purpose of the present invention is to provide a molten metal casting device that can be used satisfactorily over a long period of time and is inexpensive.

Means for Solving the Problems> In order to solve the above problems, the molten metal casting apparatus of the present invention has a structure in which a pivot shaft is inserted into the lower end of a pair of hanging arms and is connected to the side of the ladle. A holding part with an insertion hole is provided,
The hanging arm and the holding part are integrally joined by a reinforcing plate, and a mounting plate is formed in series with one of the reinforcing plates, and on the mounting plate, there are holes inserted into the insertion holes of the holding part. The present invention consists in that a support part is provided for holding the pivot shaft of the ladle which is inserted and connected, and a tilting mechanism for tilting the ladle is provided between the support part and the above-mentioned holding part.

According to the present invention having the above-mentioned configuration, since the separately formed hanging arm and the holding part are integrally joined by a reinforcing plate, it is possible to maintain the same strength as a conventional forged product and also to provide reinforcement. A mounting plate for mounting a tilting member or the like can be formed in series with the plate.

A support part is provided on the mounting plate to hold the pivot shaft of the ladle that is inserted through and connected to the insertion hole of the holding part, and
Since a tilting mechanism for tilting the ladle is provided between the support part and the holding part, the pivot axis of the ladle is connected to the support part and the mounting plate formed at the lower end of each arm. It is supported at three locations on the support part provided in the ladle, and it is possible to prevent a gap caused by wear between the pivot shaft and the arm holding part due to tilting of the ladle over a long period of time.

In addition, even if a gap occurs due to wear between the pivot shaft and the arm holding part due to the tilting operation of the ladle, the reinforcing plate is integrally joined to the holding part, and one reinforcing plate is attached to the mounting plate. are formed in series, a tilting mechanism is provided on the mounting plate, and the pivot shaft of the ladle is supported by the support part.
The misalignment between the arm and the ladle during hanging can be absorbed or softened by the reinforcing plate, the mounting plate, the supporting part, etc., and the influence on the tilting mechanism can be prevented.

Further, it is possible to prevent a large load from being applied to the tilting mechanism.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a schematic front view of the molten metal casting apparatus of the present invention, and FIG. 2 shows a schematic side view.

The molten metal casting device has a pair of hanging arms (3a) <3b
