The prior art is compared, and there are following technical effects for the utility model：Crank is directly driven by a motor, and is driven being promoted
The reliability of its application is also ensured while the working efficiency of device, and driving device can be in the original pedestal of pumping unit
It improves, while being obviously improved oil pumping mechanomotive force, moreover it is possible to greatly save its cost of investment.
Detailed description of the invention
Content expressed by each attached drawing of this specification and the label in figure are briefly described below：
Fig. 1,2 be the utility model schematic diagram.
In figure：10. motor, 11. first motors, 12. second motors, 13. third motors, 20. shaft couplings, 30. wheel hub systems

Specific embodiment
With reference to the accompanying drawing 1,2, by the description of the embodiment, making to specific embodiment of the present utility model further
It is described in detail.
A kind of driving device used for oil extractor, as shown in Figure 1, 2, including three motors 10 being fixedly mounted on pedestal A, three
Motor 10 described in platform is coaxially arranged, and two adjacent motors 10 are connected by shaft coupling 20 and constitute synchronous rotation, is located at two
The outside output end of the motor 10 of side is fixedly connected with the crank B for being arranged in the two sides pedestal A respectively.It can still use so original
Pedestal A arrange motor 10, investment reduction cost.Three motors 10 work together the power that can greatly promote driving device, full
The bigger power demand of sufficient pumping unit.Output end positioned at the motor 10 of two sides is directly connected with crank B, enables motor 10
Crank B is directly driven, is not required to separately to set retarder and is adjusted the speed, to be obviously improved the working efficiency of driving device and its reliable
Property.
Preferably, the motor 10 is permanent magnet synchronous motor or synchronous magnetic resistance motor.The efficiency of synchronous magnetic resistance motor compared with
The power factor of height, permanent magnet synchronous motor is higher, and control is simple, convenient for application.
Specifically, the motor 10 includes the first, second and third motor 11,12,13, wherein the first and second motor 11,12
Power is equal, and the power of third motor 13 is less than the power of first motor 11, and third motor 13 is set to the first and second motor 11,12
Between.As shown in Figure 1, 2, positioned at two sides the first and second motor 11,12 power are larger, volume is larger, be arranged in the two of pedestal A
Side, is located in the middle that 13 power of third motor is smaller, small volume, is mounted on pedestal A.Space can be made full use of in this way, closed
Removing the work sets motor 10, and the output power of further lifting driving device makes it meet the power demand of pumping unit.
In the present embodiment, it is preferred that the motor 10 for being located at two sides is made into the oblateness electricity that outer diameter is big, axial length is small
Machine makes it have the characteristic of the slow-speed of revolution, big torque, meanwhile, it is also convenient for the arrangement of motor 10, prevents its of motor 10 and pumping unit
He interferes structure.
Preferably, first and second motor 11,12 is same motor, the type of third motor 13 and second and third motor
11,12 is identical or different.That is, the first and second motor 11,12 should be simultaneously using permanent magnet synchronous motor or synchronous reluctance electricity
Machine, and the motor type that third motor 13 uses can be different from the first and second motor 11,12.It is connected directly in this way with crank B
The problems such as two powers of motor are all the same with type, and crank B operation is asynchronous caused by avoiding because of motor difference, to effectively protect
Demonstrate,prove the reliability of pumping unit work.
Preferably, the output end of 11,12 inside of the first and second motor is respectively provided with a hub brake 30 or third electricity
The side output end of machine 13 is equipped with hub brake 30.Hub brake 30 is used to slow down or stop the operation of pumping unit.Specifically
Can with as shown in Figure 1, hub brake 30 be set to third motor 13 one end, can also be as shown in Fig. 2, in the first and second motor
11,12 inside output end respectively sets a hub brake 30.
Preferably, the motor 10 is fixedly mounted on pedestal A by mounting rack 40.Mounting rack 40 can by 10 stabilization of motor
It is mounted on pedestal A by ground, when use adjusts the axle center height of motor 10 by adjusting mounting rack 40, is allowed to and pedestal A, song
Handle B is consistent, to can guarantee the reliability of pumping unit work.
