Abstract

The utility model relates to a top driving water faucet device for oil and water well maintenance operation. A center pipe and a hydraulic driving motor are installed on a machine body through a bearing seal and a mechanical seal. A speed changing gear is installed on the center pipe. The speed changing gear is engaged with a gear shaft installed at the shaft end of the hydraulic driving motor fortransmission. A cover seat is installed at the upper part of the upper cover of a shell. The cover seat is provided with a U-shaped pipe, an upper cover lifting handle and an aligning regulator. A quick joint is installed at the end of the U-shaped pipe. An expansion oil tank is communicated with the machine body. The utility model has the advantages that the well maintenance operations such as drilling, milling, salvaging and the like can be completed by using the hydraulic system of the existing well maintenance operation machine and the hydraulic driving motor, the gear shaft, the center pipe and the speed changing gear transmission rotating mechanism installed in the machine body; and no other auxiliary drill floors, mechanical rotary tables, kelly bars, water faucets and the like arerequired to be installed, the cost is saved, the function is reliable and the maintenance is convenient.

Description

Oil, well maintenance activity top-drive power swivel device

Technical field

The utility model is a kind of oil, well maintenance activity top-drive power swivel device.

Background technology

Oil exploitation oil, well underground work water tap only are used for the circulation of simple waterpower down-hole at present, do not have the power spinfunction, and cause the hydraulic system of traditional production rig fully effectively not utilize; And to the brill of down-hole, mill, workover treatment such as salvaging needs to install in addition auxiliary rig floor, machine carousel, kelly bar and the first-class equipment of the fire hose, causes the workover treatment cost to rise.

Summary of the invention

The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of oil, well maintenance activity top-drive power swivel device are provided.

The utility model is achieved in that body passes through bearing, mechanical seal mounting center pipe, hydraulic drive motor, and change-speed gearing is installed on central tube, the gear shaft engaged transmission that change-speed gearing and hydraulic drive motor axle head are installed; Top in case top lid is equipped with cage, and cage is provided with U type pipe, loam cake is carried handle, set upright adjuster; U type tube end is installed snap joint; Be connected to oil expansion tank with interlinking in the body.

The utility model has the advantages that, utilize the hydraulic system of existing production rig in body, to install and comprise hydraulic drive motor, gear shaft, central tube, change-speed gearing transmission rotating mechanism, just can finish brill, mill, workover treatment such as salvaging the down-hole; Do not need auxiliary rig floor, machine carousel, kelly bar and the first-class equipment of the fire hose are installed in addition, save cost, reliable in function, easy to maintenance.

Description of drawings

Figure is a structural representation of the present utility model;

The specific embodiment

Describe in detail below in conjunction with accompanying drawing: as shown in the figure, case top lid 12, housing 4, housing lower cover 11 connect and compose body by bolt, nut, and by bearing 13, mechanical seal 16 mounting center pipes 1, hydraulic drive motor 9, change-speed gearing 5 is installed, gear shaft 10 engaged transmission that change-speed gearing 5 and hydraulic drive motor 9 axle heads are installed on central tube 1; The bottom of central tube 1 is equipped with and becomes snapping head 2, on the top of case top lid 12 cage 15 is installed, and cage 15 is provided with U type pipe 6, loam cake is carried handle 7, set upright adjuster 8; Snap joint 14 is installed in U type pipe 6 ends; Be connected to oil expansion tank 3 with interlinking in the body.

Its course of work is, by production rig hydraulic pressure top-drive power swivel device elevator is blocked and to promote handle and hang and be raised to appropriate location, derrick top, the external hydraulic innage presses flexible cord to import and export pipeline and U type pipe connects the cycling use of water tengential belt by snap joint, change snapping head is installed in the bottom of central tube connects oil pipe and down-hole string, hydraulic oil is sent into the hydraulic joint of hydraulic drive motor through hydraulic line, drive hydraulic drive motor, under the effect of change-speed gearing, drive central tube and down-hole string and workover tool rotation, switch on the pump simultaneously, by U type pipe, central tube water is recycled to the shaft bottom, reaches the purpose of workover treatment.

Claims
