Utility model content
The purpose of this utility model is to provide the hydraulically powered water tap in a kind of top; It adopts top hydraulic-driven form, and relative to overhead electric drive form, top hydraulic top drives torque demand when can meet low speed, and larger moment of torsion can be provided to export; And, in the structure design, drilling well antidetonation, operation field sparkproof etc. of parts, there is obvious advantage; And structure is simple, manufacturing cost is lower.
The purpose of this utility model is achieved in that the hydraulically powered water tap in a kind of top, and for the top-drive device of drilling equipment, it is made up of agent structure, hydraulic motor and deceleration device and sealing mechanism, securing member.The agent structure of the hydraulically powered water tap in top comprises casing, case lid, drop handle, drop handle bearing pin, washing pipe and gooseneck assembly, central tube.The hydraulically powered water tap in described top adopts top hydraulic-driven form.
The deceleration device of the hydraulically powered water tap in described top adopts three grades of slowing-down structures, drives central tube to slowly run, meets torque demand during low speed, provides larger moment of torsion to export.The deceleration device of the hydraulically powered water tap in described top comprises one-level driving gear, one-level driving gear shaft, one-level driven gear, one-level driven gear shaft, secondary driving gear, secondary driven gear, secondary driven gear shaft, three grades of driving gears and central tube gear.One-level driving gear is fixedly connected with one-level driving gear shaft, and one-level driving gear engages and drives one-level driven gear; Secondary driving gear and one-level driven gear coaxial, namely secondary driving gear is fixedly connected with one-level driven gear shaft jointly with one-level driven gear, and the central axis of the center line of secondary driving gear and the center line of one-level driven gear and one-level driven gear shaft on the same line; Secondary driving gear is engaged in secondary driven gear, secondary driven gear and three grades of driving gears coaxial, namely secondary driven gear is fixedly connected with secondary driven gear shaft jointly with three grades of driving gears, on the same line, three grades of driving gears engage and drive central tube gear for the center line of the center line of secondary driven gear and three grades of driving gears and the central axis of secondary driven gear shaft; Central tube gear is fixedly connected on central tube; The turning cylinder of hydraulic motor is connected one-level driving gear shaft.Like this, when hydraulic motor works, the turning cylinder of hydraulic motor drives one-level driving gear shaft to rotate, by three grades of decelerations, drive central tube to slowly run, meet torque demand during low speed, and larger moment of torsion can be provided to export, thus reach the purpose of this utility model.
Owing to have employed technique scheme, the hydraulically powered water tap in top, relative to overhead electric drive form, not only can meet torque demand during low speed, and larger moment of torsion can be provided to export; And, in the structure design, drilling well antidetonation, operation field sparkproof etc. of parts, there is obvious advantage; And structure is simple, manufacturing cost is lower.
