Description
Technical Field
The utility model relates to a stone back cutting corner guide mechanism.
Background
The mining of the mine cave requires drilling and then rope sawing of the seam, for example, in prior art patent CN112709531a. In order to take down the stone material later, still need carry out back of body and cut at last, in the in-process of back of body cuts, the both ends of cutting the rope extend outside backward through the switching-over rotation of back of body cutting corner in the drilling hole, the cutting rope then from top to bottom cuts the stone material back gradually, along with cutting position's gradual decrease, the contained angle of cutting rope and horizontal plane diminishes gradually, if the switching-over wheel of cutting corner department lacks corresponding self-adaptation direction at this moment, can lead to cutting rope and the wheel wall of switching-over wheel to produce excessive interference and wearing and tearing, back of body cuts the instrument and damages easily, and back of body cuts is unsmoothly.
Based on this, this case provides a stone material back of body cuts corner guiding mechanism for solve above technical problem.
Disclosure of Invention
In view of the defects in the prior art, the technical problem to be solved by the utility model is to provide a stone back cutting corner guide mechanism.
In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a stone material back of body cuts corner guiding mechanism, includes the member that is arranged in penetrating the drilled hole of stone body, rotatory wheel carrier is installed to the inner tip of member, install the switching-over wheel on the rotatory wheel carrier, the rotation axis of rotatory wheel carrier is parallel with the member, the rotation axis of switching-over wheel is mutually perpendicular with the member.
Preferably, the inner end part of the rod piece is fixedly provided with a supporting disc positioned at the inner side of the rotary wheel frame.
Preferably, the shape of the supporting disc is circular, and the end face of the supporting disc is positioned on a vertical plane and perpendicular to the rod piece.
Preferably, the rotary wheel frame is a rectangular annular frame body, and the reversing wheel is arranged in the annular frame body.
Preferably, the circumference of the reversing wheel is provided with a rope winding groove.
Compared with the prior art, the utility model has the following beneficial effects:
the stone back cutting corner guide mechanism is simple in structure, two ends of the cutting rope extend out of the outside through reversing wheels at the back cutting corner in the drilling hole, the cutting rope gradually cuts the back of the stone from top to bottom, the included angle between the cutting rope and the horizontal plane gradually becomes smaller along with gradual reduction of the cutting position, and the reversing wheels at the back cutting corner synchronously and adaptively swing at the moment so as to avoid excessive interference and abrasion of the cutting rope and the wheel walls of the reversing wheels, so that the back cutting tool is not easy to damage, and back cutting is smooth.
The utility model will be described in further detail with reference to the drawings and the detailed description.
