Abstract

The invention refers to a device with which provisional consolidating frames adapted to be brought to a smaller size can be transported to the drift face and can be put in place. According to the invention this device is arranged on the cutting machine itself so that the narrow space remaining between the contour of the cutting machine and the cross section of the drift is sufficient for transporting in forward direction and putting in place the provisional consolidating frames without the necessity to retract the face advancement machine from the drift face. Thus, face advancement machines can be used which occupy the major part of the inside width of the drift, noting that the face advancing machine is maintained in its working position. The invention further describes a doorjamb frame for the provisional drift consolidation and which is particularly suitable for the device proposed.

Dependent claims

In combination with a cutting machine having at its forward end a universally pivotable arm extending forwardly, said arm carrying at its forward end a rotary cutting head:

apparatus for temporarily consolidating a gallery or drift or tunnel with consolidating frames which can be reduced in size so as to be transportable through consolidating frames already in place, said apparatus comprising a longitudinally extending support have front and rear ends means fixed to the cutting machine and forming a pivot connection between the cutting machine and said longitudinally extending support such that said support is swingable relative to the cutting machine about a horizontal transverse axis which is in a fixed position relative to the cutting machine;
means connected between the cutting machine and said support at a location rearwardly of said horizontal axis for selectively applying upward and downward forces to said support whereby the rear end of said support may be moved away from and toward the cutting machine;
feed carrier means mounted on said support for telescopic movement parallel thereto such that the forward end of said feed carrier means may be extended longitudinally beyond the front end of said support to a position overlying the universally pivotable arm of the cutting machine;
a frame transport car longitudinally movable on said feed carrier means for supporting and moving a consolidating frame, when reduced in size, from a location near the rear end of said support to a location forward of the front end of said feed carrier means;
and drive means for moving said feed carrier means parallel to said support and for moving said transport car longitudinally of said feed carrier means.
