Abstract
A rotary drill bit clutch comprises a clutching part and a protective cover of a control part, which is characterized in that a spline shaft at the right side of the clutching part is provided via a bearing with a primary external stepped ring piston which has the end connected with the protective cover and the external provided with a corresponding primary internal stepped ring cylinder body which has the outer side provided with an oil pipe joint with external end connected with an oil pipe of oil pressure system for feeding oil to the cylinder body; the left side of the clutching part is serially provided with a thrust bearing and a platen pressed against a platen of the clutching part. The utility model has reasonable design, adoption of hydraulic pressure mode, simple and energy-saving operation, suitability for distant operation, automatic compensation of friction amount, little possibility of damage, no need for frequent repairing and debugging, no impact in clutching and reversing and smooth starting.
Description
Technical field: the utility model relates to a kind of clutch, particularly a kind of rotary drill clutch.
Background technique: the rotary drill clutch of prior art, its control section generally all are mechanical types.This rig clutch, the one, must adopt manual control, relatively effort particularly when remote operation, bothers especially; The 2nd, poor reliability, amount of friction can not compensate automatically, needs frequent maintenance and debugging; The 3rd, from, close when commutation, can produce impact, start steady inadequately.
Summary of the invention: the purpose of this utility model provides a kind of new type hydraulic rotary drill clutch, to overcome the existing above-mentioned defective of prior art rig clutch.The purpose of this utility model is to improve to realize on the basis of prior art rig clutch, it comprises the guard shield of clutch part and control section, its main points are the right sides in the clutch part, by bearing the outer step type annular piston of one-level is housed on the splined shaft, the annular piston end links to each other with guard shield, the outside is provided with step type circular cylinder in the one-level corresponding with it, the oil connection that be equipped with in the outside of circular cylinder can oil-feed in cylinder body, the outer end can link to each other with the pressurized oil system oil pipe, the left side is provided with a thrust-bearing and a platen successively, and roof pressure is on the platen of clutch part.
The utility model is reasonable in design, adopts hydraulic way, and the one, handle simply laborsavingly, be particularly suitable for remote-controlled operation; The 2nd, amount of friction can compensate automatically, and is not fragile, need not frequent maintenance and debugging, good reliability; From, close commutation and do not have to impact, start steadily.
Description of drawings: accompanying drawing is that master of the present utility model looks sectional view
Embodiment: accompanying drawing has provided an embodiment of the present utility model, with reference to the accompanying drawings, 9 is clutch parts among the figure, the 8th, the guard shield of control section, right side in clutch part 9, by bearing 3 the outer step type annular piston 4 of one-level is housed on the splined shaft 2, annular piston 4 ends link to each other with guard shield 8, the outside is provided with step type circular cylinder 5 in the one-level corresponding with it, be equipped with in the outside of circular cylinder 5 can oil-feed in cylinder body, the oil connection 1 that the outer end can link to each other with the pressurized oil system oil pipe, the left side is provided with a thrust-bearing 6 and a platen 7 successively, and roof pressure is on the platen of clutch part 9.When the control pressurized oil system by oil pipe and oil connection 1 in circular cylinder 5 during oil-feed, produce pressure in the cylinder body 5, promote circular cylinder 5 and move to left, and then promote thrust-bearing 6 successively and platen 7 is moved to the left, the platen of roof pressure clutch part 9 makes master, the driven friction combination of clutch part 9; When controlling pressurized oil system by oil pipe and oil connection 1 oil return, produce negative pressure in the cylinder body, simultaneously under the spring force effect of clutch part 9, the platen of clutch part 9 loses pressure, master, the driven friction of clutch part 9 break away from mutually, thereby realize the clutch action of the utility model clutch.
