Abstract
The utility model relates to the technical field of oil extractors of oil fields, in particular to a rider-type walking-beam balance adjustment device for an oil extractor. According to the device, a rider-type counter weight is connected with a self-locking device and a locked mechanism; the self-locking device can slide on a self-locking rail of a hanging beam; the rider-type counter weight is connected with a floating nut; the floating nut is sleeved on a drive lead screw; the drive lead screw is connected with a lead screw bearing seat in a gear box; the gear box, a speed reducer and an electric motor are connected in sequence; the gear box is hinged with the hanging beam through a force transmission pin; and the hanging beam is connected with a walking beam though a hanging shaft and is positioned with the walking beam through a jack screw. By the device, a good balance effect is achieved; the range of balanced moment is widened; the device is adjusted conveniently, quickly and precisely; and the self-locking device and the locked device are safe and reliable. The defects of poor balance effect and potential safety hazards because the conventional oil extractor does not have the self-locking device or locked device are overcome.
Description
Technical field:
The utility model relates to a kind of oil-field oil pumper technical field, particularly a kind of oil pumper sliding poise type beam balance adjusting device.
Background technology:
Existing old-fashioned oil pumper is mostly without beam counterweight, and adjustment is inconvenient, efficient is low, narrow application range, and it is inaccurate to adjust balance, is difficult to reach the desirable balance effect.And the oil pumper with tunable arrangement makes mechanism have technological deficiency on safety and the function under inertia and alternating force effect without self-locking and locking device.
The utility model content:
The technical problems to be solved in the utility model provides a kind of oil pumper sliding poise type beam balance adjusting device, and this device has been realized good balance effect, widens the trimming moment scope, and easy to adjust accurately quick, the self-locking locking device is safe and reliable.Overcome existing balance of well pumping unit weak effect, had the deficiency of potential safety hazard without self-locking and locking device.
Technical solution adopted in the utility model is: a kind of oil pumper sliding poise type beam balance adjusting device comprises drop in beam; Connect self-locking device and locking mechanism on the sliding poise type balance weight, self-locking device can slide at the self-locking track of drop in beam, connect captive nut on the sliding poise type balance weight, captive nut is sleeved on the turn-screw, lead screw shaft bearing in turn-screw and the transmission case is connected, transmission case, reducer, motor connect in turn, and transmission case is hinged by power transmission pin and drop in beam, and drop in beam is connected with walking beam by hanging scroll and locates by jackscrew and walking beam.
The beneficial effects of the utility model are: the utility model has been owing to adopted the mode of sliding poise type balanced adjustment, thereby has good balance effect, and quick accurate advantage easy to adjust is widened the trimming moment scope, and the self-locking locking device is safe and reliable.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of oil pumper sliding poise type beam balance adjusting device comprises drop in beam 9; Connect self-locking device 2 and locking mechanism 12 on the sliding poise type balance weight 1, self-locking device 2 can slide at the self-locking track of drop in beam 9, connect captive nut 3 on the sliding poise type balance weight 1, captive nut 3 is sleeved on the turn-screw 4, lead screw shaft bearing in turn-screw 4 and the transmission case 5 is connected, transmission case 5, reducer 7, motor 8 connect in turn, and transmission case 5 is hinged by power transmission pin 6 and drop in beam 9, and drop in beam 9 is connected with walking beam 11 by hanging scroll 10 and locates by jackscrew 13 and walking beam 11.
During the utility model work, motor 8 work drive reducer 7 and drive turn-screw 4 rotations, driving sliding poise type balance weight 1 by captive nut 3 moves at the self-locking track of drop in beam 9, the position movement of sliding poise type balance weight 1 changes the balance arm of force and adjusts balance, thereby makes oil pumper reach desirable reliable counterbalance effect.Sliding poise type balance weight 1 is not when turn-screw 4 rotates and drop in beam 9 passes through self-locking device 2 and locking mechanism 12 is locked.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
