Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a portable holding device for steel vessels, particularly metallurgical steel vessels.

(Prior Art) In steel mills, casters and rivets, i.e. steel casters and rivets covered with refractory linings, are used to transport molten steel, and the casters and rivets have retaining brackets. The attached holding shafts are arranged opposite to each other, and this holding bracket is suspended on a crane hanging device of an indoor crane (Lueger%Lexikon der
l-10LLenLecl+nik: Foundry technology dictionary,
Vol, 5.1963. p, 240-241).

In addition to foundry ladles, small steel vessels are also often used in steel mills, for example for transporting slag, pig iron, scrap iron, etc. These containers have a special shape depending on the purpose of their use6, for example, are designed as pot-shaped and ribbed without retaining brackets. If you are planning to transport this type of caster and riveter, remove the crane hanging gear used for casting and riveting from the indoor crane, and use a special hanger that can easily hold steel containers with different structures than those used for casting and riveting. must be installed together.

OBJECTS OF THE INVENTION The present invention avoids such inconveniences by allowing a single crane to hold and transport at least two different types of steel containers, as well as providing support for different types of steel containers. The purpose is to enable the use of steel mill transport vehicles, temporary storage stands, and other equipment.

(Structure of the Invention) To achieve the above object, the present invention includes an open or closed retaining ring that surrounds a steelmaking container with a gap in the lateral direction, and a branch extending downward from the retaining ring, preferably three branches, a retaining shaft arranged in opposite directions on each side of the retaining ring axis; It consists of a recess provided in the holder and a locking means for locking the fixing means.

(Example) Figure m1 and the following diagrams show a holding device according to the present invention. ring 3
In this embodiment, the structure is designed to be a IIJ chain type, but it can also be an open type.

A downwardly extending strut 4 is firmly fixed to the retaining ring 3, and a support plate 5 is attached to the lower end thereof. Preferably, there are three struts 4, which extend around the axis 6 of the retaining device. The lower ends of the branches 4 are connected to each other by struts 17 for better stability.The retaining ring 3 is provided with a retaining bracket 8. Holding shaft 9
are arranged on both sides of the axis 6 of the holding device, facing in opposite directions. The holding brackets 8 each have an elongated hole 1 extending in the vertical direction, and are not only rotatable on the holding shaft 9 but also reciprocated by a dimension 12 in the vertical direction 11. The two brackets 13 on the retaining ring 3 have projections 14 that cooperate with projections 15 on each of the retaining brackets 8. When the retaining brackets 8 are lifted up, they are disengaged, whereas when the retaining brackets 8 are lowered, they engage with each other, so that the retaining brackets 8 are in the lowered position, i.e. after being disengaged from the indoor crane and lowered by their own weight. , remains upright.However, if the retaining device is placed on the support by the retaining bracket 8, the retaining ring 3
The holding shaft 9 is rotatable around the axis 16 of the holding shaft 9 and can be tilted.

The steelmaking container 1 has two fixing bins 17 as fixing means facing in opposite directions. In order to accommodate these fixing bins 17, the retaining ring 3 has two upwardly open U-shaped recesses 18, each of which allows the steel container 1 mounted on the retainer to be placed in the inclined position of the retainer. However, it can be closed by a ratchet 19 so that it can be held safely.

This ratchet 19 has two legs 2 arranged at an appropriate angle.
0.21, from position A where the recess 18 is opened (indicated by the nail i line in FIG. 2) to position B where the recess 18 is closed.
(shown by the solid line in Figure 12), the axis 2 of the fixing bottle 17
It is designed to spin by rotating around a horizontal axis 23 extending parallel to 2.

When the ratchet 19 is in the closed position B, the vertically downwardly protruding legs 20 allow the steel making container 1 to descend and lock the fixing bin 1.
Immediately upon contact with 7, the ratchet 19 is automatically rotated to the closed position B side. rll of the ratchet 19 In the nailing position B, the clamp bolt 24 engages and disengages the horizontal leg 21 of the ratchet 19 and is removed by being tightened by the ratchet. The clamp bolt 24 is rotatable around an axis 25 parallel to the rotation axis 23 of the ratchet F19.

One of the columns 4 has a bracket 26 with a U-shaped upwardly open seat 27 into which a bin 28 provided on the steel vessel 1 can be inserted. When the steelmaking container 1 is placed on the holding device 6 - at this time, the steelmaking container 1 is suspended by a crane using a hanging hook 29 provided on its upper edge. It must be noted that the pin 28 is inserted into the U-shaped seat 27. Pillar 4-1
One has, near its lower end, another seat 30 which serves to transmit the tilting moment to the holding device. Such a tilting moment is transmitted to the branch office 4 by the arm 31 of the lever ramp 32 via the bracket 30 (FIG. 4).

The ladle tilt table 32 has two fixed support stands 33,
The lower end of the holding bracket 8 can be inserted there. In order to tilt the holding device together with the steelmaking vessel 1, a lever ramp 32 is provided.
An arm 31 rotatably mounted on is driven, so that it comes into contact with the seat 30 and the holding device is tilted about the axis of the holding shaft 9.

With respect to its external dimensions, in particular the distance 34 between the holding brackets 8, the dimensions of the shape of the holding brackets 8, the diameter 35 formed by the branches 4, the holding device can be used for holding, transporting and temporarily placing steel casting ladles. The attachment means corresponds to a ladle for steel casting so that it can also be applied to a steel manufacturing container having external dimensions different from those for steel casting and (1) the ladle.

(Effects of the Invention) As is clear from the above description, according to the present invention, the steel container can be accommodated by an indoor crane equipped with a crane hanger adapted to the holding shaft of the holding device. It can be transported.

To renew the lining, the steel caster and rivet are tilted, and for that purpose steel mills are usually equipped with operating stations such as a riveter ramp. and rivet ramps make it possible to tilt steelmaking containers without using an indoor crane.

The indoor crane can then be used for other tasks. In order to be able to use the original riveting ramp for engraving steel containers with different dimensions for casting and riveting, the external dimensions of the holding device for the steel manufacturing container that can be transported to the operating table, especially those that can be mounted on the holding shaft, are required. Preferably, the distance between the retaining brackets is equal to the outer dimensions of the cast and rib.

In order to securely fix the steel container, the locking means is preferably formed by a ratchet having two legs arranged at an appropriate angle to each other and rotatable about a horizontal axis. A rotatably mounted clamp bolt is adapted to engage and disengage the ratchet when the ratchet is in its closed position.

In order to easily hold the holding device with a crane hanging device, the holding bracket is attached to the holding shaft through a long hole provided in the vertical direction so that it can be rotated and reciprocated in the vertical direction. Preferably, means are provided between the retaining bracket and the retaining ring to engage and disengage by vertical movement of the retaining bracket, and to fix the retaining bracket in a vertical position relative to the retaining ring in its lowered position. This type of structure is known per se as a foundry and a rib (ibid., Vol. 1.5.
