Description

[Detailed Description of the Invention] The present invention relates to a donation deck for repairing a tilted pot, which is used in a steel factory to repair a pot that has been turned over.

This type of donation deck is not only safe but also easy to use, in order to use it as a scaffold for repairing or replacing the sliding nozzle attached to the casting pot after tilting the casting pot. There is a need.

As a typical example, a horizontal deck is provided at the end of the work floor so that it can be tilted via a support pin, a cylinder is provided below the deck, and the action of this cylinder moves the deck horizontally or It is known that it can be tilted.

However, this method requires a relatively large-capacity drive source in order to sufficiently withstand the load during work.
There was also a lack of safety.

Therefore, the present invention aims to solve the above-mentioned problems and provide a safe and economically superior donation deck for repairing casting pots.

Embodiments of the present invention will be described below with reference to the drawings.

1 is a casting pot, and the casting pot 1 is overturned by a casting pot tilting device (not shown).

Reference numeral 2 denotes a donation deck, which can be horizontally or tilted about a support shaft 4 at the end of the work floor 3.

An upper link member 5 is rotatably attached to the lower surface of the deck 2 by a support pin 6, and is rotated by a rotatable lower link member 7 attached to the lower deck 11 and a fulcrum pin 8 by a support pin 10. They are movably engaged and form a link mechanism.

An inclined stopper 9 is provided at the upper end of the lower link member 7.
is permanently installed.

Reference numeral 12 denotes a hydraulic (or pneumatic) cylinder, one end of which is supported by a support shaft 13 of the lower floor 11 so as to be rotatable, and the other end of the rod is fixed to the lower link member 7 by a pin 15.

In this example, the inclined stopper 9 is provided at the upper end of the lower link member 7 and one end of the cylinder iron is attached to the lower link member, but the inclined stopper 9 is provided at the lower end of the upper link member 5 and one end of the cylinder iron is attached to the lower link member. Even if it is attached to the upper link member, similar effects can be obtained.

However, if the hydraulic cylinder 12 does not operate, the second
As shown in the figure, the deck 2 is tilted downward with the support shaft 4 as a fulcrum by the link mechanism 5.7, but the cylinder 12
When the rod 14 is extended and the lower link member 7 is continued to be pushed, the lower link member stands up, and the inclined stopper 9 presses the rear part of the upper link member 5 to maintain the deck 2 in a horizontal state.

Furthermore, as shown in FIG. 1, the link mechanisms 5 and 7 take on an inverted dogleg shape and maintain a state of being supported by the inclined stopper 9.

As described above, according to the present invention, when working on deck 2,
Since the load is borne by the link mechanisms 5 and 7, the hydraulic cylinder 12 only needs to have enough capacity to rotate the deck 2.

During work, the tilt stopper 9 can always maintain the locked state.

Therefore, the present invention has a simple mechanism and operation, is safe and economical, and has extremely high practical value.

Claims (1)

[Scope of utility model registration request] In a donation deck installed to repair an overturned casting pot, a horizontal deck is rotatably provided at the end of the work floor via a support shaft, and an upper portion is attached to the bottom of the deck via a support pin. The upper end of the link member is attached, the other end of the upper link member is connected to the upper end of the lower link member having an upwardly inclined stopper via a fulcrum pin, and the lower end of the lower link member is connected to the subfloor via the support pin. At the same time, one end of the cylinder rond, which is supported by the support shaft of the lower floor, is engaged with a pin at an appropriate position of the lower link member, and the expansion and contraction of the cylinder rond causes the link mechanism to act, so that the deck can be horizontally and tilted.
