Abstract
The utility model relates to an autonomous actuating device of a rotating disc, which mainly solves the problem that the existing rotating discs can not be individually adjusted, can not achieve continuous speed regulation, and a gear wheel is easy to be damaged which is caused by unstable mechanical speed regulation. The utility model is characterized in that an alternating current variable frequency motor (1) is connected with an output shaft (5) of a second speed gear box (4) through a joint slack (3), the gear wheel of the output shaft (5) of the second speed gear box (4) is meshed with the gear wheel on an output shaft (6) of the second speed gear box (4), the output shaft (6) of the second speed gear box (4) is connected with a drive shaft (7), and the drive shaft (7) is connected with a rotor disc (2). The autonomous actuating device of a rotor disc has the advantages that the rotating speed of the rotor disc can be individually adjusted, and continuous and stable speed regulation are achieved.
Description
Technical field:
The utility model relates to oil drilling field turntable used drive unit, especially rotating disk drive device.
Background technology:
In the drilling well field, the rotating disk of existing rig drives through compound box or drive chain case by direct current generator, thereby cause that rotary speed and slush pump jig frequency can not be regulated separately, the contradiction of mutual restriction, rotary speed divides several grades of speed changes, can not realize stepless speed regulation, owing to be mechanical speed change thereby not mild, fragile gear, and have the low defective of drilling efficiency, and the control of driller's machinery brake lever, the drilling safety coefficient is low.
The utility model content:
In order to solve that stepless speed regulation can not be regulated, can not be realized to existing rotary speed separately and because of the problem of the not mild and fragile gear of mechanical speed change, the utility model provides a kind of rotating disk drive device, and this rotating disk drive device has rotary speed can regulate, realize stepless speed regulation and the mild characteristics of speed change separately.
The technical solution of the utility model is: this rotating disk drive device comprises rotating disk and alternating-current variable frequency motor, alternating-current variable frequency motor links to each other by the power shaft of shaft coupling with the second gear gearbox, gear on the second gear gearbox power shaft is meshed with gear on the output shaft of second gear gearbox, the second gear output shaft of gear-box links to each other with power transmission shaft, and power transmission shaft links to each other with rotating disk.
The utlity model has following beneficial effect: this rotating disk drive device is realized the independent infinitely variable speeds of rotating disk owing to take such scheme, has satisfied the needs of drilling technology; Realize the modularized design of rotating disk, rotating disk running part and braced structures thereof easily; Trouble hunting is convenient. and rotating disk adopts DBS numerical control converter technique, control system digitlization, informationization; Solved thoroughly that machine dimensions drill rotary speed and slush pump jig frequency can not be regulated separately, the contradiction of mutual restriction, the drawback that drilling efficiency is low.The independent electricity of rotating disk drives the reliability that has improved rig floor on the rig power greatly, has saved the energy.Motor adopts dynamic braking, to satisfy the requirement of handling complicated downhole drill accident, realizes flexible transmission and protection drilling tool purpose of safety.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-alternating-current variable frequency motor among the figure, 2-rotating disk, 3-shaft coupling, 4-second gear gearbox, 5-power shaft, 6-output shaft, 7-power transmission shaft.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this rotating disk drive device comprises rotating disk 2 and alternating-current variable frequency motor 1, alternating-current variable frequency motor 1 links to each other with the power shaft 5 of second gear gearbox 4 by shaft coupling 3, gear on second gear gearbox 4 power shafts 5 is meshed with gear on the output shaft 6 of second gear gearbox 4, second gear gearbox 4 output shafts 6 link to each other with power transmission shaft 7, and power transmission shaft 7 links to each other with rotating disk 2.
During actual the use, this rotating disk drive device integral body is sunken under the rig floor face, and concordant with the rig floor face.Drive rotating disk by an alternating-current variable frequency motor 1, shaft coupling 3 through second gear gearbox 4 and power transmission shaft 7; rotating disk is by alternating-current variable frequency motor 1 drive; directly control motor 1 and inertia brake in the control room by valve member and handle by the driller; rotating speed can stepless speed regulation between 0-300 rev/min when realizing rotating disk rotary drilling operating mode, and the torque protection scope can be set arbitrarily in 0-100%.Realize driller's automated drilling, avoided the shortcoming of the dumb and poor reliability of machine driving.Alternating-current variable frequency motor 1, second gear gearbox 4, rotating disk 2 are fixed on the module, and be easy for installation.Alternating-current variable frequency motor 1 adopts dynamic braking and urgent air clutch brakes, to satisfy the requirement of handling complicated downhole drill accident, realizes flexible transmission and protection drilling tool safety.The rotating speed of rotating disk can be according to the requirement of drilling technology, and manual adjustments alternating-current variable frequency motor 1 rotating speed is to obtain desirable rotary speed.Collect the operational factor of rotary tray motor by frequency converter, PLC through bus, calculate rotary speed, torque, and on the control flow in the driller house, show.PLC can set the rotating disk torque by programming, and the operational factor of control motor makes the torque dynamic duty at setting range.
