Embodiment 1

[0033] Such as figure 1 As shown, it is a schematic diagram of the structure position of the present invention in the front view. The disc frequency conversion motor 1 is directly connected to the reducer 2, and is directly installed on the shaft of the reducer 2 through the hollow shaft of the disc frequency conversion motor 1, and the reducer 2 is installed On the upper end of the pumping unit installation frame 3, the lower end of the disc frequency conversion motor 1 is equipped with an oil pumping power device 4, and the lower end of the oil pumping power device 4 is provided with a support plate 412 and a rib plate 413, and the support plate 412, the rib plate 413 and the oil pumping The machine mounting frame 3 is fixedly connected, and the rib plate 413 is fixedly connected to the bottom of the support plate 412 for auxiliary support of the support plate 412 .

[0034] Such as Figure 2-Figure 3 As shown, it is the left view of the installation state of the I-type dis...

Embodiment 2

[0038] Such as Figure 4-Figure 5 As shown, it is the left view of the installation state of the type II disc frequency conversion motor. The difference between the motor installation device 4 and the embodiment 1 is that there are two sets of adjustment shafts 41, nuts I 42, nuts II 43, spring pressure plates 44, damping springs 45, springs Backing plate 46, shock-absorbing rubber sleeve 47 and fixing plate 48 are respectively fixed on the same supporting plate 412 through corresponding washers 49, spring washers 410 and outer hexagonal bolts II 411; Type variable frequency motor foot 11.

[0039]The invention is reasonable and simple in structure, convenient and flexible in use, convenient and practical, and is suitable for pumping units in oil fields. The characteristics of the patent of the present invention are: the disc-type variable frequency motor 1 is directly installed on the shaft of the reducer 2, and the use of spring support has two advantages. The first is that...

Abstract

The invention relates to an oil pumping power device and a mounting method. The technical problem that according to an existing oil pumping power device, a motor bottom foot fixing mode is easy to damage a motor is solved. The device is provided with a motor and a speed reducer. The motor is a disc type variable-frequency motor. The device is also provided with an installation device. The installation device is provided with an adjusting shaft, a nut, a damping spring, a supporting plate and a damping rubber sleeve, wherein the adjusting shaft is in threaded connection with the nut, the adjusting shaft is in threaded connection with the disc type variable-frequency motor through threads, the supporting plate and the nut are supported through the damping spring, and the lower end of the adjusting shaft is isolated from the supporting plate through the damping rubber sleeve. The method can be widely applied to mounting and fixing of the motor for the oil field pumping unit.

Description

technical field [0001] The invention relates to the field of electric motors, in particular to an oil pumping power device and an installation method. Background technique [0002] Most of the motors used in oil field pumping units are single-speed three-phase asynchronous motors, which are driven by the motor through belts and pulleys, and then decelerated by the reducer to drive the pumping device to work. In the actual working process, because the downhole condition of the oil well is constantly changing, it is necessary to adjust the number of up and down strokes of the pump rod of the pumping unit. Because the single-speed three-phase asynchronous motor has only one fixed speed, it cannot fully meet the needs of the site. Then it will be realized by replacing the pulley and the belt, and because the oil wells are all in the wild, the distribution is relatively scattered, the replacement is time-consuming and labor-intensive, and the cost of manpower and material resour...
