The effect of winch is lifting drilling tool, has assisted and has pulled out sleeve pipe and realize percussion drilling and use.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can realize simply and easily the lifting of lifting drum and the friction disk type winch of braking function.
According to technical scheme provided by the invention, described friction disk type winch, on elevator axle, be fixed with inner ring body, on the cylindrical of inner ring body, there is external toothing, on the external toothing of inner ring body, slidably connect active friction plate, in the inner circle of active friction plate, have active friction plate internal tooth, active friction plate internal tooth and external toothing engagement are fixed with quiet dish on inner ring body; On elevator axle, be socketed with screw-casing, between the cylindrical of elevator axle and the inner circle of screw-casing, there is gap, on the cylindrical of screw-casing, there is outside thread, on the cylindrical of screw-casing, be bolted with tep reel nut, on tep reel nut, by bearing, be rotatablely equipped with compression plate, on compression plate, be fixed with Moving plate; On elevator axle, be rotatablely equipped with reel, on reel, be fixed with outer ring body, on outer ring body, be fixed with seal cover cap, in the inner circle of outer ring body, there is internally toothed annulus, on the internally toothed annulus of outer ring body, slidably connect two driven friction disks in left and right, on the wall of the left and right sides of every driven friction disk, be all fixed with friction lining, between quiet dish and Moving plate, be provided with spring.
On spring, be socketed with spring housing.
In the inner circle of Moving plate, there is Moving plate internal tooth, the external toothing selectivity engagement of Moving plate internal tooth and inner ring body.
On the left side of reel, be fixed with seal cover cap, the interior circular hole of seal cover cap coordinates with the cylindrical of tep reel nut.
Clutch of the present invention is reliable, steadily, when power-transfer clutch and brake strap unclamp, drilling tool is by deadweight decline, time saving and energy saving, and compact conformation, processing ease, is adapted at applying on similar rig.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
As shown in the figure, this friction disk type winch, on elevator axle 1, be fixed with inner ring body 2, on the cylindrical of inner ring body 2, there is external toothing 2.1, on the external toothing 2.1 of inner ring body 2, slidably connect active friction plate 3, in the inner circle of active friction plate 3, have active friction plate internal tooth, active friction plate internal tooth and external toothing 2.1 engagements are fixed with quiet dish 4 on inner ring body 2; On elevator axle 1, be socketed with screw-casing 5, between the inner circle of the cylindrical of elevator axle 1 and screw-casing 5, there is gap, on the cylindrical of screw-casing 5, there is outside thread, on the cylindrical of screw-casing 5, be bolted with tep reel nut 6, on tep reel nut 6, by bearing, be rotatablely equipped with compression plate 7, on compression plate 7, be fixed with Moving plate 8; On elevator axle 1, be rotatablely equipped with reel 9, on reel 9, be fixed with outer ring body 10, on outer ring body 10, be fixed with seal cover cap 11, in the inner circle of outer ring body 10, there is internally toothed annulus 10.1, on the internally toothed annulus 10.1 of outer ring body 10, slidably connect two driven friction disks 12 in left and right, on the wall of the left and right sides of every driven friction disk 12, be all fixed with friction lining 13, between quiet dish 4 and Moving plate 8, be provided with spring 14.
On spring 14, be socketed with spring housing 15.
In the inner circle of Moving plate 8, there is Moving plate internal tooth, the external toothing 2.1 selectivity engagements of Moving plate internal tooth and inner ring body 2.
On the left side of reel 9, be fixed with seal cover cap 16, the interior circular hole of seal cover cap 16 coordinates with the cylindrical of tep reel nut 6.
Working process of the present invention 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 are separated with quiet dish 4, and power-transfer clutch unclamps, and brake strap unclamps, and drilling tool declines by deadweight.
