Abstract
The utility model discloses a multifunctional motor head. A case body of the motor head is provided with a driving pair, liquid motors are respectively arranged on the two ends of a drive gear wheel. A driven gear is arranged on a center tube. The upper end of the center tube is provided with a sealed ring and a loop overlapping which can achieve activity of inertia separation. A cover base which is arranged on the upper portion of the case body is provided with a pressing sleeve and a pressing pad, wherein the upper end of the pressing pad is provided with joint components with end sockets, the lower end of the center tube is provided with a lower joint. The multifunctional motor head of the utility model has big torque output, and can achieve the multifunctions of mud drilling, air drilling, auger drilling, and further can put dynamite down to the bottom of shaft via the center tube or a hollow auger stem of the motor head. The utility model is used in exploratory drilling engines of oil and mineral resources.
Description
The utility model relates to a kind of multifunctional motive power head that is used for oil mine prospection wagon drill.
The present unit head that uses on the oil mine prospection wagon drill generally is that hydraulic motor is coupled together with dynamic head main spindle or hydraulic motor is directly connected with dynamic head main spindle through shaft coupling.By a fluid motor-driven, so the output torque of unit head is little; In addition, the main axle structure of unit head has also limited the function and the purposes of rig, and for oil mine prospection wagon drill, have drilling well, the unit head of function such as explosive is transferred in the centre will bring a lot of convenience to exploration.
The purpose of this utility model is for overcoming above-mentioned weak point, is a kind ofly paid two multifunctional motive power heads that hydraulic motor, end socket, lower contact are formed by gear drive and design.
The utility model content: a kind of multifunctional motive power head, comprise casing, slide, hydraulic motor and tool joint, it is characterized in that: be provided with gear drive in the casing and pay, hydraulic motor is equipped with at the two ends of driving gear respectively, driven gear is loaded on the central tube, and the central tube upper end is provided with sealing ring and the ring set of realizing quiet moving separation; The inside that is loaded on the cage on casing top is provided with clamping sleeve, clamping pad, and the adapter assembly of band end socket is equipped with in the clamping pad upper end; The central tube lower end is provided with lower contact, is provided with sealing between the two, is equipped with key between central tube and loose-proof sleeve top, loose-proof sleeve middle part and lower contact top and loose-proof sleeve bottom and lower contact bottom and is connected.Described end socket is the hollow end socket that water bores end socket or band valve.
The utlity model has following advantage:
1. because the driving gear two ends that the gear drive of unit head is paid respectively are provided with a hydraulic motor, and promptly unit head is driven by double motor, so unit head can export bigger moment of torsion, and its numerical value is 1000-5000NM.
2. select water for use when the end socket of the adapter assembly on central tube top and bore end socket, when tool joint is installed in the central tube bottom, unit head has the function of mud drilling, air drilling and spiral drilling well.
3. under the condition of not dismantling with drill rod thread, can be directly from the hollow end socket of band valve with the explosive lower going-into-well at the bottom of.
4. both are in quick condition when the screw thread of lower contact lower center tube is not tightened, and realize locking by key on lower contact and the central tube and loose-proof sleeve.
Description of drawings:
Fig. 1 is the utility model schematic diagram (analysing and observe).
Fig. 2 is a hollow end socket part drawing (analysing and observe).
Further specify the utility model below in conjunction with drawings and Examples.
Multifunctional motive power head (Fig. 1) is bored end socket 10, hollow end socket 9, adapter assembly and rolling bearing and is formed by hydraulic motor 3, casing 1, driving gear 2, driven gear 14, central tube 15, sealing mat 12, ring set 13, cage 4, clamping pad 5, clamping sleeve 7, back of the body mother 6, locking device 16, tool joint 18, shackle casing 17, water.In the casing of multifunctional motive power head gear drive is housed and pays, this transmission is paid by driving gear and driven gear and is intermeshed.Casing is a split-type structural, so that processing and manufacturing, between the corresponding axis hole of the axle journal at the two ends of driving gear and casing rolling bearing is housed, and rotates flexibly.Each is connected the two ends of driving gear with the main shaft of hydraulic motor, is provided with key therebetween, to transmit power.Rolling motor through screw on the end face of the corresponding axis hole of casing.Driven gear is loaded on the central tube and by key and is connected with central tube.Central tube is installed on the casing through a pair of taper roll bearing.The upper end of central tube be provided with can quiet moving separation two sealing rings and a ring set, ring set respectively establish a sealing ring up and down.Upper sealing gasket is spacing by clamping pad, and clamping pad is regulated control by clamping sleeve, and clamping sleeve is loaded in the cage by screw thread, can be by the female locking of the back of the body after clamping sleeve regulates.Adapter assembly is installed in the clamping sleeve, and adapter assembly is made up of union 11, assembly body 8 and end socket.Union is loaded on the sidewall of assembly body, is processed with through hole on the corresponding side walls, when union with after mud or compressed air piping are communicated with, mud or compressed air are transported in the wellhole through central tube.Assembly body upper end is connected with end socket through screw thread.The lower end of central tube is connected with lower contact through screw thread, and lower contact outside suit locking device, and the upper bush of locking device is connected through key with central tube, and the lower sleeve of locking device is connected with lower contact through key, and the lower sleeve fixed outside has shackle casing.Can select mud drilling, air drilling and spiral drilling well for use according to the difference of earth formation.At this moment bore end socket in the top of center tubular axis filled with water, can carry out drillng operation in the fit on lower contact of the lower end of center tubular axis.Between central tube bottom and lower contact, be provided with " O " shape sealing ring 19, change hollow end socket (Fig. 2), install different lower contacts in the central tube lower end and can carry out the inside prescribe medicine, the utlity model has multiple function in the central axis upper end, easy to use.
Claims (2)
1. multifunctional motive power head, comprise casing, slide, hydraulic motor and tool joint, it is characterized in that: be provided with gear drive in the casing and pay, hydraulic motor is equipped with at the two ends of driving gear respectively, driven gear is loaded on the central tube, and the central tube upper end is provided with sealing ring and the ring set of realizing quiet moving separation; The inside that is loaded on the cage on casing top is provided with clamping sleeve, clamping pad, and the adapter assembly of band end socket is equipped with in the clamping pad upper end; The central tube lower end is provided with lower contact, is provided with sealing between the two, is equipped with key between central tube and loose-proof sleeve top, loose-proof sleeve middle part and lower contact top and loose-proof sleeve bottom and lower contact bottom and is connected.
