Utility model content
The technical problems to be solved in the utility model is to overcome the deficiency that existing roof delamination monitoring instrument exists aspect waterproof, and a kind of waterproof and then raising Instrument measuring precision and the mining roof plate absciss layer monitor in serviceable life are provided.
A kind of mining roof plate absciss layer monitor of waterproof, comprise the displacement meter that is arranged on hell outside and the anchor fluke that is arranged on the dark basic point of described boring place, described displacement meter inside comprises steel wire, and on described displacement meter housing, comprise steel wire outlet, described steel wire is extracted out and is connected with described anchor fluke from described steel wire outlet, described displacement meter is arranged on a side of described boring, and described displacement meter is connected with the angle sheave of bottom and described steel wire close contact near a side of boring, described steel wire is parallel with the length direction of described boring and in tensioning state in boring, the bottom of described angle sheave exports lower than described steel wire.
The mining roof plate absciss layer monitor of waterproof described in the utility model, wherein said angle sheave is connected with described displacement meter by bracing frame, support frame as described above is two, and by the connected support body of back shaft, the center of described angle sheave has axis hole, is enclosed within on described back shaft.
The mining roof plate absciss layer monitor of waterproof described in the utility model, on the excircle of wherein said angle sheave, be provided with described steel wire is carried out spacing around groove.
The mining roof plate absciss layer monitor difference from prior art of the utility model waterproof is:
The mining roof plate absciss layer monitor of the utility model waterproof is simple in structure, workable; Use angle sheave to change steel wire trend, make displacement meter fixed position transfer to position, hell side from hell, the water producing in boring flows directly into tunnel along steel wire, can not enter into displacement meter, waterproof and then raising Instrument measuring precision and serviceable life.
In the mining roof plate absciss layer monitor of the utility model waterproof, on the excircle of described angle sheave, arrange around groove, can carry out spacing to the position of described steel wire, back shaft is used for connecting angle sheave and bracing frame, reduces the frictional resistance of angle sheave, makes monitoring more accurate.
Below in conjunction with accompanying drawing, the mining roof plate absciss layer monitor of waterproof of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of mining roof plate absciss layer monitor of the prior art;
Fig. 2 is the structural representation of the mining roof plate absciss layer monitor of waterproof described in the utility model;
