Abstract
The utility model relates to a power transmission device of an oil rig. The oil rig comprises a low level main case, a low level bevel gearbox, a high level bevel gearbox and a high level main case; wherein, the low level main case and the low level bevel gearbox are connected with a transmission device; the high level bevel gearbox and the high level main case are connected with a rig turntable; a universal shaft is connected between the low level bevel gearbox and the high level bevel gearbox; the low level main case and the low level bevel gearbox form a combined case structure with all transmission pairs arranged in the identical case body; a driving bevel gear is positioned at the output shaft of the mainframe; the high level bevel gearbox and the high level main case also form a combined case structure with all transmission pairs arranged in the identical case body; and the driven bevel gear is arranged on the input shaft of the mainframe. The utility model has the advantages of fewer components, compact structure, high precision of relative positions of all the components, good transmission effect, less gear vibration, fewer leakage points of lubricant oil, strong sealing structure, and significant reduction of oil leakage.
Description
Technical field
The utility model relates to oil-well rig, specifically is a kind of actuating unit of oil-well rig.
Background technology
Drilling for oil/during the natural gas well, for safety, well head will be installed a cover preventer that adapts with strata pressure, so have to improve the rig floor height, makes rig floor up to 9 to 10 meters.Because the diesel engine oneself requirement of rig should not be installed too high, general setting height(from bottom) 1.5 meters with interior machine room backstage on, so just the platform problem of climbing of transmission of power occurred, promptly the power that how 1.5 meters high diesel engines is sent passes to height on 9 to 10 meters rig floor, drive rotating disk, drive drilling rod, drill bit rotation.
Adopted bushroller chain to solve the above-mentioned platform problem of climbing in the past, but owing to chain intersect and the incompatibility of self structure to produce noise big, leakage of oil is serious, pollute problems such as well site surrounding environment, so, universal drive shaft occurs in last century end and climbed the platform technology, referring to Fig. 1, the power of diesel engine 1 output passes to low level umbrella gear box 3 through low level mainframe box 2, horizontal output is become vertical output, pass to high-order umbrella gear box 5 through universal drive shaft 4 again, again vertical output is become horizontal output, pass to high-order mainframe box 6 again, like this,, finish and climb the platform transmission by the transmission of low level with regard to successfully having realized power to a high position.
Though universal drive shaft is climbed the platform technology and solved the noise problem that bushroller chain is climbed platform, also thoroughly do not solve the leakage of oil problem.Connect because mainframe box, umbrella gear box all are cantilevered axle each other, axiality always has error, and stressed is not fine, after running a period of time, the seal clearance of bearing strengthens, and still has oil leakage phenomenon, mainframe box, umbrella gear box all are two, and oil leak point is many.
Particularly: the progression of transmission is many, and each level all is independently parts, and the relative position of each parts has error unavoidably during not only cost height, and installation, influences the transmission effect, and the vibration of mainframe box and umbrella gear box is asynchronous, and gear weares and teares easily, and application life is short; Overall structure is not compact yet, and area occupied is big, and the area of rig floor is very limited.
Summary of the invention
The utility model is climbed the deficiency of platform technology at above-mentioned universal drive shaft, and a kind of actuating unit of oil-well rig is provided.Few, the compact conformation of the number of components of this device, each parts relative positional accuracy height, transmission is effective, and gear vibration is little; Oil leak point is few, seals not easy to wearly, and leakage of oil significantly reduces.
The technical scheme that the utility model adopted is:
A kind of oil-well rig actuating unit comprises the low level mainframe box, the low level umbrella gear box that are connected with drive unit, is connected with universal drive shaft between the high-order umbrella gear box that is connected with Rotary table for drilling machine, the high-order mainframe box, low level umbrella gear box and high-order umbrella gear box; The order of connection of all parts is: drive unit, low level mainframe box, low level umbrella gear box, universal drive shaft, high-order umbrella gear box, high-order mainframe box and Rotary table for drilling machine; Described low level mainframe box and low level umbrella gear box are the mould assembling structures, and its all transmissions all are arranged in the same casing, and driving bevel gear is arranged on the output shaft of main frame; Described high-order mainframe box and high-order umbrella gear box also are the mould assembling structures, and its all transmissions all are arranged in the same casing, and driven bevel pinion is arranged on the power shaft of main frame.
The beneficial effects of the utility model are:
Because a high position, the mainframe box of low level, umbrella gear box are the mould assembling structure, the number of components of transmission device reduces, compact conformation, and cost also reduces; Each parts relative positional accuracy improves, and transmission is effective, and gear vibration is little; Oil leak point is few, and bearing seal face is not easy to wear, and leakage of oil significantly reduces.
