Abstract

A melting furnace is provided, that may contain a furnace shell, a furnace shell moving mechanism that supports the furnace shell so as to be movable on an installation surface, a pipe or a wiring that has one end fixed to the furnace shell and has at least partially, a flexible portion, and a stand. The stand may contain a supporting part that supports a halfway portion of the pipe or the wiring, and a stand moving part that is coupled to the supporting part and moves the supporting part on an installation surface in synchronization with movement of the furnace shell, in which the stand is mounted on the installation surface so as to be movable up and down with respect to the furnace shell.

First claim

What is claimed is:

1. A melting furnace, comprising:
a furnace shell;
a furnace shell moving mechanism that supports the furnace shell so as to be movable on an installation surface;
a pipe or a wiring that has one end fixed to the furnace shell and has at least partially a flexible portion; and
a stand that comprises a supporting part that supports a halfway portion of the pipe or the wiring, and a stand moving part that is coupled to the supporting part, the stand moving part comprising a wheel that moves the supporting part on the installation surface with movement of the furnace shell, wherein the stand is mounted on the installation surface so as to be movable in an up-down direction with respect to the furnace shell, and
a coupler comprising a furnace shell side-coupler fixed to the furnace shell, a stand side-coupler fixed to the stand, and a coupling shaft directly connecting the furnace shell side-coupler and the stand side-coupler.

2. The melting furnace according to claim 1 , wherein
the supporting part is coupled to the furnace shell so as to be movable up and down by the coupler, which transmits movement of the furnace shell induced by the furnace shell moving mechanism to the wheel.

3. The melting furnace according to claim 2 , wherein
the coupling shaft couples the stand to the furnace shell so as to make the stand rotatable within a plane containing the up-down direction, and so as to make the stand rotatable in a vertical plane with respect to the furnace shell and the furnace shell-side coupler via the coupling shaft.

4. The melting furnace according to claim 2 , further comprising
a track installed in order to guide the movement of the wheel.

5. The melting furnace according to claim 1 , wherein
the stand moving part is provided at a halfway portion of the supporting part.

6. The melting furnace according to claim 1 , further comprising
an insulation installed in at least one of a portion between the supporting part and the furnace shell, a portion between the supporting part and the stand moving part, and a portion between the furnace shell and the furnace shell moving mechanism.

7. The melting furnace according to claim 6 , wherein
the furnace shell, the furnace shell moving mechanism and the supporting part are independently grounded.

8. The melting furnace according to claim 1 , wherein
the installation surface is tiltable in a state of supporting the furnace shell and the stand.

9. The melting furnace according to claim 1 , further comprising:
a lock mechanism in at least one of the furnace shell moving mechanism and the stand, wherein the lock mechanism inhibits movement of the furnace shell and the stand on the installation surface.

10. The melting furnace according to claim 1 , wherein:
the furnace shell moving mechanism comprises an annular support frame having a gear member, a bearing that supports the annular support frame, and a gear provided adjacent to the annular support frame,
the furnace shell is fixed on the annular support frame,
the gear is rotatable within a plane parallel to a plane of the platform, and the rotation shaft thereof is connected to a motor, and
the platform is supported by a supporting base fixed on a floor surface, and the platform is tiltable in a state of supporting the furnace shell and the stand.

11. A melting furnace, comprising:
a furnace shell;
a furnace shell support configured to support the furnace shell so as to be movable on an installation surface;
one of a pipe and a wire having one end fixed to the furnace shell and having at least a partially-flexible section; and
a stand comprising:
a stand support configured to support a halfway section of the one of the pipe and the wire; and
a wheel coupled to the stand support and configured to move the stand support on the installation surface with movement of the furnace shell, wherein the stand is mounted on the installation surface so as to be movable in an up-down direction with respect to the furnace shell, and

a coupler comprising a furnace shell side-coupler fixed to the furnace shell, a stand side-coupler fixed to the stand, and a coupling shaft directly connecting the furnace shell side-coupler and the stand side-coupler.
