Abstract
The utility model provides a rotary table gear to oil drills, which is composed of two angle gear boxes, two cardan shafts, a drive and a driven chain wheels, a chain, an air clutch, a bearing and a flange plate, wherein, the two angle gear boxes and the two cardan shafts as a main body. A power input shaft of a first angle gear box is connected with a winch through the clutch, the chain wheel and the chain. The first angle gear box and a second angle gear box are connected by the cardan shafts. The second angle gear box and the rotary table are also connected by the cardan shafts. When the utility model is moved, the disassembly, assembly and alignment are very convenient. The utility model has the advantages that the sealing and lubricating effect is good, the service life of gear components can be extended, and the installation direction and center distance are adjustable. The utility model is suitable for drill floors with various height.
Description
The utility model relates to the oil-well rig power drive system, between winch and rotating disk, and a kind of mechanical oil-well rig turntable transmission device.
At the oil-well rig of usefulness, its rotary table transmission device has the moving and machine driving two big classes of fax both at home and abroad, and the machine driving class has chain drive and universal drive shaft transmission dual mode.China all is chain transmission mode at the oil-well rig of usefulness basically at present, promptly a sprocket wheel on the winch root axle is linked by the sprocket wheel on chain and the rotating disk.In order to make chain and sprocket wheel that good lubricated and safety in production be arranged, design and installation chain cover and guard shield.Like this, each resettlement all will dismantle, reset chain and guard shield.Frequent dismounting is not only taken a lot of work, is required great effort, and can damage chain cover and guard shield.If airtight lubricated being damaged changes into and manually water oil lubrication, insufficient lubrication and don't convenient will shorten chain application life.Reinstall necessary centering simultaneously, have deviation just to make chain bump, twist slightly, even fracture, also can influence the rotating disk life-span.Also have and adopt the universal drive shaft kind of drive, though solved dismounting inconvenience and centering problem, have a gearbox position that inconvenience is installed, the installation of mud slot type preventer is also had any problem, and also because universal drive shaft is longer, can not be suitable for for the rig floor that is higher than 4.5 meters.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect part of prior art, and a kind of rotary table transmission device of special use is provided for the oil-well rig in usefulness.Dismounting and centering are all very convenient during this device resettlement, and airtight lubricating also is guaranteed, and can improve rotating disk greatly and use life.Mounting arrangement is more reasonable, can both be suitable for for the rig floor of differing heights.
Above-mentioned purpose of the present utility model realizes by following technical proposals:
This device is based on two right angle gear boxs and two universal drive shafts, in addition by the master, formed by movable sprocket, chain, tire type clutch, bearing and flange etc.The power input shaft external part of first right angle gear box is equipped with by the gentle tire formula of movable sprocket clutch, is linked by chain and drive sprocket by movable sprocket.Link by first universal drive shaft between first and second two right angle gear boxs, link by second universal drive shaft between second right angle gear box and the rotating disk.Direction between them and center to center distance all can be adjusted.
The two ends of above-mentioned two universal drive shafts all adopt flange plate structure mode and two corresponding line shafts of right angle gear box to link, and only need the flange connecting bolt of dismounting universal drive shaft one end to get final product during resettlement.
Two bevel gears are housed in above-mentioned first right angle gear box, are installed in respectively on its power input, the output shaft.Its power input, output shaft are installed on the casing by bearing.
Above-mentioned second right angle gear box is a cuboid, and a pair of bevel gear is respectively adorned in inside, two ends, is installed in respectively on its power input, the output shaft.Its power input, output shaft are installed on the casing by bearing.Driving gear in the driven gear in the first pair of bevel gear and the second pair of bevel gear is installed in the same two ends of long intermediate propeller shaft respectively.
The casing of above-mentioned two right angle gear boxs all processes with the steel plate assembly welding.Wherein in second right angle gear box grease pump is housed.Two casings all are fixed on the crossbeam of derrick base with bolt and nut.
The utility model compared with the prior art, its major advantage is: oil-well rig when resettlement, no longer include so much disassemble and assemble work amount, and centering is very easy to when reinstalling; Whole airtight lubricated being guaranteed of right angle gear box can prolong the application life of drive disk assembly greatly; Two-stage right angle gear box and two universal drive shaft combinations match, and installation direction and adjustable center distance make the rig floor layout more reasonable, are applicable to the rig floor of various height.
Accompanying drawing is structure of the present utility model and scheme of installation.
Each code name among the figure: the 1st, the output chain gear on the intermediate shaft of drawworks, the 2nd, driving chain, the 3rd, tire type clutch, the 4th, the power input shaft of first right angle gear box, the 5th, drive sprocket, the 6th, first right angle gear box, the 7th, the output shaft of first right angle gear box, 8 is first universal drive shaft, and 9 is power input shafts of second right angle gear box, and 10 is second right angle gear box, the 11st, intermediate propeller shaft, 12 is output shafts of second right angle gear box, and 13 is second universal drive shaft, the 14th, and rotating disk, 15-20 is a bevel gear, 21-24 is method half dish, 25, the 26th, duplex bearing, 27-34 are that single shaft holds.
Details are as follows to embodiment of the present utility model in conjunction with the accompanying drawings:
During resettlement, only need dismounting flange 21 and 24(or 22 and 23), take chain 2 again apart, can be separately winch, rotating disk, this device three, carrying separately, other need not dismantled everywhere.When reinstalling, owing to 6,10,14 three positions preestablish, so the centering of needn't taking a lot of work can guarantee that rotating disk 14 is in optimum position state work.
The power transmission process of this device is: the power of winch output is passed to sprocket wheel 5 by sprocket wheel 1 and chain 2, passes to power input shaft 4 by clutch 3 again.First right angle gear box 6 is passed to power power input shaft 9 in second right angle gear box 10 again by universal drive shaft 8, by intermediate propeller shaft 11 power is passed to power output shaft 12 again, by universal drive shaft 13 power is passed to rotating disk 14 at last, makes rotating disk drop into operate as normal.When requiring the rotating disk stall, air clutch 3 to be thrown off, just idle running on axle 4 of sprocket wheel 5 is cut off to rotating disk power is provided.
