Abstract
The utility model discloses a noveltwo-speed hydraulic rotating disk for petroleum well repairing, which is suitable for the well drilling work or the repair of the petroleum (gas) and the water injection well of an oilfield. Two-speed hydraulic rotating disk for petroleum well repairing is independently driven by a liquor motor, is rotated by a vertical shaft, and is speed changed to a big gear which is under a turn table via two-position tooth type clutch; then, a kelly and a drilling string are driven by a master bushing which is in the turn table. A bidirectional ratchet wheel and ratchet pawl braking devices are installed below the turn table. The noveltwo-speed hydraulic rotating disk for petroleum well repairing has compact structure; compared with the existing structure, the volume and the weight can be reduced by 1/5 to 1/3. The noveltwo-speed hydraulic rotating disk for petroleum well repairing has the advantages of compact structure, easy fabrication, convenient installation and use, agility, and safety; moreover, a small repairing team can replace some work of a big repairing team, so the development cost of an oilfield can be reduced.
Description
The utility model relates to a kind of petroleum well workover with two grades of speed changes novel rotating disk that surges, and it is specially adapted to the workover treatment of oil well, the natural gas well, water injection well, also can be used for drillng operation.
Existing rotating disk is by extraneous speed change, power is inputed to the horizontal axis of rotating disk by chain or universal drive shaft, bevel pinion passes to bevel gear wheel and turntable through the horizontal axis end, drives drill string rotating by the master bushing on the turntable again, and the brake ratchet of rotating disk is installed in the middle of the horizontal axis.
Existing rotating disk adopts by extraneous variable speed drives, and through the structure of chain or universal drive shaft input, floor space is big, and loosely organized numerous and diverse, the installation site is restricted, adjusts inconvenient; And rotating disk is subjected to external force big, and its volume weight is also bigger; This feels inconvenient more to requiring to move frequent well workover team.
The purpose of this utility model provides a kind of power drive and rotating disk and is combined into one and has and become reducing gear and arrestment mechanism, compact conformation, manufacturing, installation, novel rotating disk easy to use.
The utility model is achieved in that petroleum well workover is made up of six parts with two grades of speed changes rotating disk that surges, and they are housing, fluid motor, change reducing gear, turntable, master bushing and arrestment mechanism.Its middle shell is the accole of other parts.The power drive of this rotating disk is a fluid motor, and splined shaft is directly passed in moment of torsion that fluid motor produced and motion.Balladeur train and interior external gear are housed on the splined shaft.Balladeur train is by shift fork, and declutch shift shaft and speed change handgrip slide up and down it on splined shaft, to realize two grades of needed different engagements of speed change, even gear shaft obtains two rotating speeds (when the fluid motor invariablenes turning speed).And gear shaft rotates by the gear wheel that engagement drives on the turntable, i.e. turntable and master bushing rotation.Master bushing goes to drive kelly bar and whole drill string rotating again.The balladeur train of this rotating disk, interior external gear, gear shaft, linkage gear, gear wheel all are roller gears.For finishing well workover and drillng operation, rotating disk also should be tied with well head or rig floor by screw.
Fluid motor can be installed in housing (rotating disk) above or below, be installed in the more favourable operation in below, relatively rationally.Fluid motor just must be combined into one with rotating disk after the general assembly.
The arrestment mechanism of this rotating disk is made up of ratchet, ratchet, torsion spring, pin and binding handle.Wherein ratchet is an one with gear wheel, and each two of ratchet, torsion spring and control handgrips, so that from both direction, rotating disk is carried out stop.
For guarantee above-mentioned principal character part on housing the installation site accurately, reliable, flexible operation also should have separately accessory as accessories such as bearing, felt, pad, gland, screw, lubricant greases.
The utility model has been cancelled Bevel Gear Transmission because of having increased fluid motor, makes it simple and compact for structure, and volume and weight reduces 1/5～1/3 than present rotating disk.The processing and manufacturing simple economy; Installation, easy to use; And can make light maintenance drilling team replace some operation of overhaul drilling team, for Oilfield developing has reduced cost.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the main sectional view of this novel rotating disk.
Fig. 2 is vertical view (first half), upward view (Lower Half) and the partial sectional view of this novel rotating disk.
Now the structure and the working condition thereof of the novel rotating disk that the utility model proposed are further described in conjunction with Fig. 1, Fig. 2.
By splined shaft (7), balladeur train (8), interior external gear (9), gear shaft (10), linkage gear (11), gear wheel (13), speed change handgrip (12), shift fork (22), declutch shift shaft (23) and place kick (24) are formed with reference to two grades of change reducing gears of Fig. 1, Fig. 2 (2).Fluid motor (1) is screwed the below in housing (5).Splined shaft (7) is at first passed in moment of torsion that it produced and motion, and splined shaft (7) drives balladeur train (8) rotation.Balladeur train (8) can be done on splined shaft (7) by shift fork (22) promotion (shift fork is subjected to speed change handgrip (12) operation) and slide up and down simultaneously, and sliding position is limited by the locating slot of place kick (24) and declutch shift shaft (23).When balladeur train (8) is in when the next, position promptly shown in Figure 1, it is to make gear shaft (10) drive gear wheel (13) by linkage gear (11), thereby drives turntable (3) and master bushing (4) rotation, turntable this moment (3) the acquisition slow-speed of revolution.As upwards promoting speed change handgrip (12), shift fork will be stirred on the balladeur train (8) and move, and mesh with interior external gear (9), interior external gear (9) goes to drive gear wheel (13), turntable (3) and master bushing (4) rotation by gear shaft (10) again, and turntable this moment (3) will obtain high rotating speed.
Turntable (3) can be considered as a big hollow shaft, and for guaranteeing its running accurately flexibly, it is furnished with base bearing (14) and auxiliary bearing (15).For preventing that dirts such as drilling fluid from entering main and auxiliary bearing, the two ends of turntable (3) are provided with the maze type hermetically-sealed construction.Gear wheel (13) is a roller gear, compares with the bevel gear of existing rotating disk, and it is all simple, easy that it makes installation.Gear wheel (13) combines by key and turntable (3).Ratchet (16) below the gear wheel (13) is for locked turntable (3) usefulness, and it is a part of arrestment mechanism (6).Arrestment mechanism (6) also comprises ratchet (17,17), binding handle (18,18), torsion spring (20,20) and pin (21) in addition.
When turntable (3) when freely rotating, pin (21) inserts in the hole of two binding handles (18,18), and ratchet (17,17) leaves ratchet (16), does not play braking action.Dial time-out when pin (21), discharge binding handle (18), because the effect of torsion spring (20), ratchet (17) is embedded in the race of ratchet (16), and turntable (3) can not inhour be rotated.When discharging binding handle (18), turntable (3) can not clockwise rotate.When discharging binding handle (18,18), turntable (3) is being braked simultaneously along counter-clockwise direction.
Whole rotating disk is connect with well head or the rig floor of bolt (19) with its work mutually by the flange under the housing (5).
