The invention relates to a double-friction-sheet type clutch windlass for a drilling machine. The friction sheet type windlass is characterized in that an internal ring body is fixed on a windlass shaft; an external gear ring is formed on the excircle of the internal ring body; an active friction plate is connected on the external gear ring of the internal ring body in a sliding way; an active friction plate internal gear is formed on the internal circle of the active friction plate; a static disc is fixedly arranged on the internal ring body; a spiral sleeve is sleeved on the windlass shaft; a reel nut is screwed on the excircle of the spiral sleeve; a compression plate is rotatably arranged on the reel nut through a bearing; a movable plate is fixedly arranged on the compression plate; a winding drum is rotatably arranged on the windlass shaft; the external ring body is fixedly arranged on the winding drum; the internal circle of the external ring body is provided with an internal gear ring; left and right two passive friction plates are connected on the internal gear ring of the external ring body in a sliding way; friction sheets are fixedly arranged on the left and right two side walls of each passive friction plate; and a spring is arranged between a static plate and the moving plate. The friction sheet type windlass provided by the invention is reliable and stable in clutching, compact in structure, easy in operation, and is suitable for being promoted and used in similar drilling machines.
Description
Technical field
The present invention relates to a kind of two Ortlinghaus plate clutch winchs of rig, the invention belongs to construction machinery and equipment (rig) technical field.
Background technology
The effect of winch is lifting drilling tool, has assisted and has pulled out sleeve pipe and realize percussion drilling usefulness.
Summary of the invention
The objective 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, be fixed with inner ring body at the elevator axle, cylindrical at inner ring body has external toothing, external toothing at inner ring body slidely connects active friction plate, have the active friction plate internal tooth on the inner circle of active friction plate, active friction plate internal tooth and external toothing engagement are fixed with quiet dish at inner ring body; Be socketed with screw-casing at the elevator axle, have the gap between the cylindrical of elevator axle and the inner circle of screw-casing, have outside thread on the cylindrical of screw-casing, be bolted with the tep reel nut at the cylindrical of screw-casing, on the tep reel nut, be rotatablely equipped with compression plate by bearing, be fixed with Moving plate at compression plate; Be rotatablely equipped with reel at the elevator axle, be fixed with outer ring body at reel, be fixed with seal cover cap at outer ring body, inner circle at outer ring body has internally toothed annulus, two driven friction disks about the internally toothed annulus of outer ring body slidely connects, on the wall of the left and right sides of every driven friction disk, all be fixed with friction lining, between quiet dish and Moving plate, be provided with spring.
Be socketed with spring housing at spring.
Inner circle at Moving plate has the Moving plate internal tooth, the external toothing selectivity engagement of Moving plate internal tooth and inner ring body.
Left side at reel is fixed with seal cover cap, and the interior circular hole of seal cover cap cooperates with the cylindrical of tep reel nut.
Clutch of the present invention is reliable, steadily, drilling tool is by deadweight decline when power-transfer clutch and brake strap unclamp, time saving and energy saving, and compact conformation, processing ease is adapted at applying on the similar rig.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with specific embodiment.
As shown in the figure, this friction disk type winch, be fixed with inner ring body 2 at elevator axle 1, cylindrical at inner ring body 2 has external toothing 2.1, external toothing 2.1 at inner ring body 2 slidely connects active friction plate 3, 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 at inner ring body 2; Be socketed with screw-casing 5 at 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, cylindrical at screw-casing 5 is bolted with tep reel nut 6, on tep reel nut 6, be rotatablely equipped with compression plate 7 by bearing, be fixed with Moving plate 8 at compression plate 7; Be rotatablely equipped with reel 9 at elevator axle 1, be fixed with outer ring body 10 at reel 9, be fixed with seal cover cap 11 at outer ring body 10, inner circle at outer ring body 10 has internally toothed annulus 10.1, two driven friction disks 12 about the internally toothed annulus 10.1 of outer ring body 10 slidely connects, on the wall of the left and right sides of every driven friction disk 12, all be fixed with friction lining 13, between quiet dish 4 and Moving plate 8, be provided with spring 14.
Be socketed with spring housing 15 at spring 14.
Inner circle at Moving plate 8 has the Moving plate internal tooth, the external toothing 2.1 selectivity engagement of Moving plate internal tooth and inner ring body 2.
Be fixed with seal cover cap 16 in the left side of reel 9, the interior circular hole of seal cover cap 16 cooperates 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 is so that Moving plate 8 overcomes the elastic compression of spring 14 to the right, 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.
