Abstract
The utility model provides a hydraulic power head for water well drilling machines, which is characterized in that a central main shaft which is provided with an output gear is vertically installed on the center of a box body, hydraulic motors which are provided with drive gears are symmetrically installed on both sides of the central main shaft, and each drive gear is driven through an identical double reduction gear and is simultaneously transferred to the output gear of the central main shaft. A core pipe which is provided with a mud injection pipe and a gaspipe joint is fixed by a bracket on the box body. The core pipe which is fixed and the central main shaft which is rotated are sealed by a plurality of layers of V-shaped sealing rings. The utility model has the advantages of simple structure and convenient movement. The weight of a whole machine is lightened. The use range of geographical working condition is enlarged. The hydraulic power head for water well drilling machines is provided with a mechanical twisting and discharge drilling rod. Manpower is saved. Working efficiency is enhanced.
Description
Technical field
The utility model relates to a kind of rig that is used for hydrological well, especially a kind of water drilling rig hydraulic power head.
Background technology
Traditional rotary drilling machine has parts such as gearbox, rotating disk, hook, water tap, kelly bar, and the gearbox volume that especially drives rotating disk is big, makes complete machine weight big, moves heavy, especially difficult to move even one step especially in the desert region; In addition, the unloading drilling rod needs manpower auxiliary in drilling process, wastes time and energy.
Summary of the invention
The utility model provides a kind of volume little for solving the technical problem that exists in the known technology, and complete machine is in light weight, unloading drilling rod water drilling rig hydraulic power head easily.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of water drilling rig hydraulic power head, by casing, the central principal axis that has central through hole of casing is stretched out at the two ends up and down of installing in the casing, be movably arranged on the hollow core tubes that connects mud tube and gas-tpe fitting that has of alignment of shafts through hole upper end, be installed in the sealing ring between alignment of shafts through hole and core pipe, be installed in the joint that has the jointed rod internal thread of main shaft lower end, be packed in the output gear on the central principal axis in the casing, and two hydraulic motors that have power input driving gear are formed, described two hydraulic motor bilateral symmetry are distributed in the central principal axis both sides, also each installs the jackshaft that has two deceleration driven gears between the driving gear of two hydraulic motors and central principal axis output gear, and two driven gears on each jackshaft mesh simultaneously with the driving gear of hydraulic motor and the output gear of central principal axis respectively; Described sealing ring is a multilayer V-shaped seal ring up and down, is lined with a spacer ring therebetween, pressure ring is equipped with in the upper end; Described central principal axis upper end is shaped on external screw thread, and the nut that compresses pressure ring is installed by external screw thread; Described casing also is equipped with the support of fixed core pipe and joint; The terminal pad that be threaded in addition between described main shaft lower end and the tool joint, key is connected; The lubricating pump of lubricated casing middle gear also is installed in the described casing, the eccentric bushing that drives lubricating pump also is housed on the jackshaft.
Advantage and the good effect that the utlity model has are: owing to replaced the gearbox and the rotating disk of traditional rotary drilling machine with hydraulic power head, not only simplify the structure but also alleviated complete machine weight greatly, thereby enlarged the scope of application of rig in the Special geography operating mode; In addition, hydraulic power head has the ability of rotating, thereby can realize mechanical unloading drilling rod, and is time saving and energy saving, significantly reduces service working time, thereby increases work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the vertical central principal axis 1 that has central through hole of installing in the center in casing 7, the top and bottom of casing are stretched out at the two ends up and down of central principal axis.Also be fixed with the output gear 2 that drives the central principal axis rotation on the central principal axis 1 in the casing by key.For enough power is provided to main shaft, on the casing 7 of main shaft both sides, is vertically installed with 9, two hydraulic motor output shaft of two hydraulic motors and stretches in casing and respectively be fixed with driving gear 8.In order to add big speed ratio; The driving torque that increases central principal axis respectively installs the jackshaft 3 that has double reduction driven gear 5,6 additional between the driving wheel of two hydraulic motors and central principal axis output gear, each driving gear 8 is meshed with each driven gear 6, and each driven gear 5 is meshed with output gear 2 simultaneously.In order to solve the gear-driven lubrication problem of two-stage, lubricating pump 19 also is installed in casing, the eccentric bushing 4 that drives lubricating pump 19 is installed in the bottom of a jackshaft.Upper end at the central through hole of central principal axis is movably installed with core pipe 11, and the upper end of core pipe is connected with the joint that has stuffing hole 12 13 that injects mud and air, and the support 10 of fixed core pipe and joint.For the seepage that prevents that sound from separating, multilayer V-shaped seal ring 16 and pressure ring 15 up and down are installed also between central principal axis central through hole and core pipe.In order to strengthen the sealing axial distance, in the multilayer V-shaped seal ring, be lined with a spacer ring 18.Nut 14 and the locking nut 17 of regulating the V-shaped seal ring degree of tightness is installed at the upper end of central principal axis screw thread.Central principal axis lower end screw thread is connected with terminal pad 21, and the terminal pad lower end installs the joint 22 (can tighten drilling rod and carry out drilling well when the center main shaft is just changeing, can unload drilling rod automatically again when the center main shaft reverses) that has the jointed rod internal thread.In order to gain in strength, also be provided with key 20 at the connection of thread of central principal axis lower end and terminal pad.For hydraulic power head is moved up and down exactly at the mast track, the gusset piece that directive wheel also is installed in the both sides of casing 7 and connects with lifting pressurization wire rope.
