Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
As shown in the figure, this friction disk type winch, be fixed with inner ring body 2 on elevator axle 1, has external toothing 2.1 on the cylindrical of inner ring body 2, slidably connect active friction plate 3 on the external toothing 2.1 of inner ring body 2, have the active friction plate internal tooth on the inner circle of active friction plate 3, active friction plate internal tooth and external toothing 2.1 engagements are fixed with quiet dish 4 on inner ring body 2; Be socketed with screw-casing 5 on elevator axle 1, has the gap between the inner circle of the cylindrical of elevator axle 1 and screw-casing 5, has outside thread on the cylindrical of screw-casing 5, be bolted with tep reel nut 6 on the cylindrical of screw-casing 5, be rotatablely equipped with compression plate 7 by bearing on tep reel nut 6, be fixed with Moving plate 8 on compression plate 7; Be rotatablely equipped with reel 9 on elevator axle 1, be fixed with outer ring body 10 on reel 9, be fixed with seal cover cap 16 on outer ring body 10, has internally toothed annulus 10.1 on the inner circle of outer ring body 10, slidably connect two driven friction disks 12 in left and right on the internally toothed annulus 10.1 of outer ring body 10, all be fixed with friction lining 13 on the wall of the left and right sides of every driven friction disk 12, be provided with spring 14 between quiet dish 4 and Moving plate 8.
Be socketed with spring housing 15 on spring 14.
Has the Moving plate internal tooth on the inner circle of Moving plate 8, the external toothing 2.1 selectivity engagements of Moving plate internal tooth and inner ring body 2.
Be fixed with seal cover cap 16 on the left side of reel 9, the interior circular hole of seal cover cap 16 coordinates with the cylindrical of tep reel nut 6.
Working process of the present utility model is as follows:
Operating personal moves right tep reel nut 6 by operating handle, tep reel nut 6 compresses compression plate 7, compression plate 7 makes Moving plate 8 overcome to the right the elastic compression of spring 14, Moving plate internal tooth and external toothing 2.1 engagements, Moving plate 8, driven friction disk 12, active friction plate 3 and quiet dish 4 fitting together tightly, thereby reach the function of reel 9 brakings, finally realize the function of drilling tool lifting.
Operating personal makes tep reel nut 6 to left movement by operating handle, and under the elastic force effect of spring 14, Moving plate 8, driven friction disk 12, active friction plate 3 separate with quiet dish 4, and power-transfer clutch unclamps, and brake strap unclamps, and drilling tool descends by deadweight.
