Abstract
Many hydraulic motors for ultradeep well oil-well rig synchronously drive turntable structure. and comprise a rotating disk main body, described rotating disk main body is furnished with multiple hydraulic motor power synchronous input structure.Its concrete structure is: the power output shaft of multiple hydraulic motor is connected with shaft coupling, the other end of this shaft coupling is connected by key with the line shaft of rotating disk, the other end of this line shaft is connected with bevel pinion, and bevel pinion and the bevel gear wheel be installed in rotating disk main body engage and drive dial movement.In the utility model, single hydraulic motor has the advantage that volume is little, manufacture is simple and cost is low, overcome single large hydraulic motor needed for separate power input queued switches rotating disk or motor manufactures in present stage and produces the problem of difficulty, give full play to that hydraulic motor controllability is good simultaneously, commutation steadily and the advantage such as electrodeless variable-speed overcomes drilling well time motor drive rotating disk to be short of power when low speed and stall and the problem of poor controllability, thus improve ultradeep well drilling efficiency.
Description
Technical field
The utility model relates to the rotating-table apparatus technical field of oil-well rig, particularly relates to a kind of fluid motor-driven rotating-table apparatus for ultradeep well oil-well rig.
Background technology
Existing ultradeep well oil-well rig type of drive has three kinds.The first be traditional by diesel engine outputting power to chain or belt, import power into reducer, then pass to the bevel pinion of rotating disk through universal drive shaft by reducer output shaft, bevel pinion drives the auger tooth of rotating disk to rotate, thus obtains required torque.This kind of structure has the shortcomings such as transmission chain length, efficiency are low, noise is large.The second is that the output shaft of a motor is directly connected universal drive shaft by power transmission to bevel pinion, thus drives the auger tooth of rotating disk to rotate, and obtains required torque.Although this structure overcomes the shortcoming of the first structure, motor when low speed or stall for drilling rod provides required moment of torsion to have certain difficulty.The third is the shortcoming in order to overcome motor rotating disk, have developed a kind of rotating disk replacing motor to input as power by a hydraulic motor, this rotating disk is to have taken into account size little, under lightweight prerequisite, play the advantage of hydraulic motor, make oil rotating disk have the advantages such as lightweight, easy for installation, speed adjustable range is wide, controllability is good, meet the needs of situ of drilling well.The shortcoming of above three kinds of rotating disks is when drilling ultradeep well, and the power input of existing rotating disk can not meet ultra-deep well drilling needs.
Utility model content
The purpose of this utility model is drive rotating disk to be short of power when low speed or stall for existing motor and provide a kind of many fluid motor-driven rotating-table apparatus for ultradeep well oil-well rig, overcome rotating disk to be short of power under low speed, stall and high pulling torque state, the problems such as traditional rotating disk size is large, structure is not compact and speed adjustable range is narrow.
For this reason, the technical scheme adopted is:
Many hydraulic motors for ultradeep well oil-well rig synchronously drive turntable structure. and comprise a rotating disk main body, described rotating disk main body is furnished with multiple hydraulic motor power synchronous input structure.
Described multiple hydraulic motor power synchronous input structure is: the power output shaft of the multiple hydraulic motors arranged in described rotating disk main body is connected with shaft coupling, the other end of this shaft coupling is connected by key with the line shaft of rotating disk, the other end of this line shaft is connected with bevel pinion, and bevel pinion and the bevel gear wheel be installed in rotating disk main body engage and drive dial movement.
Described key one end holds out against the bearing nut be rotatably mounted on line shaft, and the other end of this bearing nut holds out against on the inner ring of the bearing on described line shaft.
Described multiple hydraulic motor power synchronous input structure is four hydraulic motor power synchronous input structures.
In the utility model when the hydraulic motor being positioned at rotating disk four direction synchronously drives, by shaft coupling by power transmission to power input shaft, the bevel pinion on power input shaft and bevel gear wheel engage each other and rotate as rotating disk provides enough moments of torsion.In this structure, single hydraulic motor has the advantage that volume is little, manufacture is simple and cost is low, overcome single large hydraulic motor needed for separate power input queued switches rotating disk or motor manufactures in present stage and produces the problem of difficulty, give full play to that hydraulic motor is efficient, controllability good, commutation is steady simultaneously and the advantage such as electrodeless variable-speed overcomes drilling well time motor drive rotating disk to be short of power when low speed and stall and the problem of poor controllability, thus effectively improve the production efficiency of ultradeep well probing.

Fig. 1 is plan structure schematic diagram of the present utility model;
Fig. 2 is that A-A in Fig. 1 is to schematic diagram;
Fig. 3 is that B-B in Fig. 1 is to schematic diagram.
Detailed description of the invention
The utility model is further illustrated for four fluid motor-driven turntable structures below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3, a kind of four hydraulic motors for ultradeep well oil-well rig synchronously drive turntable structure, comprise four hydraulic motor 11 power synchronous input structures of rotating disk main body 14 and upper setting thereof.Be specially: the power input shaft 3 of described rotating disk is provided with hydraulic motor 11, hydraulic motor 11 is fixed on fixed head 9 by bolt 10; The other end of fixed head 9 is fixed by the front panel 13 of bolt 12 by fixed head 9 and rotating disk; The power output shaft of hydraulic motor 11 is connected with shaft coupling 8 one end, and the other end of shaft coupling 8 is connected with the line shaft 3 of rotating disk by key 6; Key 6 is fixed on the line shaft 3 of rotating disk by bolt 7, and key 6 one end be fixed holds out against bearing nut 5, and the other end of bearing nut 5 holds out against the bearing 4 on the line shaft 3 of rotating disk; The other end of line shaft 3 is provided with bevel pinion 2, and bevel pinion 2 engages each other with the bevel gear wheel 1 of rotating disk.
Described key 6 one end holds out against the bearing nut 5 be rotatably mounted on line shaft 3, and the other end of this bearing nut 5 holds out against on the inner ring of the bearing 4 on described line shaft 3.The benefit of this connection is that namely key 6 carries out axial location to the bearing 4 that the line shaft 3 of rotating disk fills, and plays again the effect connecting line shaft 3 and shaft coupling 8 simultaneously, ensures stable drive.
