The specific embodiment
With reference to the accompanying drawings embodiment of the present utility model is elaborated.
As Figure 1-3, Fig. 1 is the elevation of the utility model wheel type oil pumping unit embodiment; Fig. 2,3 is respectively the left view and the right view of the utility model wheel type oil pumping unit shown in Figure 1.
Wherein, on the support 1 of wheel type oil pumping unit rack platform 2 is set, transmission device (following it is elaborated with reference to Fig. 4) and drive 5 are placed on the rack platform 2, and drive 5 is driven by this transmission device.
The upper end of first polished rod 13 of counterweight and second polished rod 15 links to each other with the end of the first polished rod wire rope 12 with the second polished rod wire rope 14 respectively each other.The other end of the first polished rod wire rope 12 and the second polished rod wire rope 14 separately each other the reverse acting spiral formula be wrapped on the drive 5 more than 1.5 circles, and be fixed on the drive 5 by tightener 10a and 10b respectively.Tightener 10a and 10b all are arranged in the drive 5, can make polished rod wire rope 12,14 be fixed in drive 5 and are thrown off by drive 5, and can adjust the length that polished rod wire rope 12,14 is extended by drive 5.
Assembly pulley rope clamp 11 is set on the rack platform 2, when the first polished rod wire rope 12 and the second polished rod wire rope 14 during by rack platform 2, by assembly pulley rope clamp 11 it is clamped, purpose is that its frame is lived the location, thereby make the polished rod 13,15 that drives by polished rod wire rope 12,14 do upper and lower more stably moving both vertically, can not be subjected to the influence of strong wind, reduce the wearing and tearing and the eccentric wear of polished rod.
The structure of the transmission device in the utility model twin-well wheel type oil pumping unit is described below with reference to Fig. 4.As shown in Figure 4, be placed in this transmission device on the rack platform 2 comprise variable-frequency motor 9, by the reducer 7,8 that variable-frequency motor drives, drive 5 is installed on the output shaft of reducer 8.Wherein, the axis of variable-frequency motor 9, reducer 7,8 and drive 5 all be arranged in parallel, and makes variable-frequency motor 9 be positioned at the side of drive 5.Putting in this manner not only saved the space, and owing to gear shaft all be arranged in parallel, so gear drive is more reasonable.
When variable-frequency motor 9 under the control of switch board 16, rotate with the commutation that threshes that the revolution in the prescribed limit is frequent, thereby driven gear 18 is done clocklike positive and negative rotation, and other 5 gears 19,20,21,22 and 23 in the reducer 7 follow gears 18 to do forward and reverse rotation synchronously.Gear 24 and 25 in the reducer 8 obtains the transmission of reducer 7, thereby drives drive 5.This shows that the power of variable-frequency motor 9 outputs has been delivered on the drive 5 by reducer 7 and reducer 8, do clocklike forward and reverse rotation thereby drive drive 5.
Again as shown in Figure 1, when drive 5 is done clocklike forward and reverse rotation, first polished rod and second polished rod are respectively under the drive of the first polished rod wire rope 12 and the second polished rod wire rope 14, vertically do reverse each other rising and descending motion, thereby drive the alternately oil pumping of two mouthfuls of oil well pumps in the oil well.
