Description
Technical field
The utility model belongs to Mechanical Driven equipment technical field, more particularly to a kind of driving equipment used for oil extractor.
Background technology
Pumping unit is a kind of lifting equipment for exploiting oil, the pumping unit of beam type since its is simple in structure, easy to use,
It can be most widely used for a long time in the work specified point of the round-the-clock operating in oil field.In the prior art, beam pumping unit is usual
Power is provided by three phase electric machine, the high-speed rotation of motor is changed into slowly running for crank, and by crank, company through retarder
Rotary motion is become the upper and lower reciprocating motion of pumping unit horsehead by bar, walking beam mechanism, and deep well pump work is driven through polished rod eye assembly
Make.The retarder mechanical loss of this pumping unit is big, needs often to safeguard so that the use cost of pumping unit remains high.With
The development of synchronous magnetic resistance motor and permanent magnet synchronous motor, the synchronous magnetic resistance motor of low speed high torque and setting for permanent magnet synchronous motor
Meter is more mature with manufacturing technology, and new solution party is provided to improve pumping unit driving equipment efficiency, reducing maintenance cost
Case.
Utility model content
The purpose of this utility model is to provide a kind of driving equipments used for oil extractor, can effectively reduce equipment use cost.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of driving equipment used for oil extractor, including solid
Two motors of the Dingan County on pedestal, the motor coaxle arrangement described in two, the output terminal that two motors are located inside are connected simultaneously
Form synchronous rotation, the output terminal positioned at outside is fixedly connected respectively with being arranged in the crank of pedestal both sides.
The prior art is compared, and there are following technique 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 is improved, so as to greatly save its cost of investment.
Description of the drawings
To this specification, the content expressed by each attached drawing and the label in figure are briefly described below：
Fig. 1,2 be the utility model schematic diagram.
In figure：1. motor, 2. shafts, 3. hub brakes, 4. mounting brackets.
Specific embodiment
Below in conjunction with the accompanying drawings 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 equipment used for oil extractor, as shown in Figure 1, 2, including two motors 1 being fixedly mounted on pedestal A, two
Motor 1 described in platform is coaxially arranged, and the output terminal that two motors 1 are located inside is connected and forms synchronous rotation, positioned at the defeated of outside
Outlet is fixedly connected respectively with being arranged in the crank B of pedestal A both sides.Original pedestal A arrangements motor 10 still may be used in this way,
Investment reduction cost.The output terminal of two motors 10 is directly connected with crank B so that motor 10 can directly drive crank B, be not required to
The another retarder that sets carries out speed governing, so as to be obviously improved the working efficiency of driving device and its reliability.
Preferably, the motor 1 is permanent magnet synchronous motor or synchronous magnetic resistance motor.The efficiency of synchronous magnetic resistance motor compared with
Height, the power factor of permanent magnet synchronous motor is higher, and control is simple, convenient for application.
Preferably, the output terminal of each 1 inside of the motor is respectively provided with a hub brake 3, and hub brake 3 is used for
Slow down or stop the operation of pumping unit, each motor 1 respectively sets a reliability that can guarantee braking.
Preferably, the motor 1 described in two is connected by shaft 2.As shown in Figure 1, the outer diameter of motor 1 is big, axial length
It is small, it can not be connected if being directly fixedly mounted on pedestal A with crank B, therefore two motors 1 are divided into the two of pedestal A
Side.Again since the length of pedestal A is larger, the shaft end of two motors 1 can not be directly connected to, thus added and turned between two motors 1
Axis 2, two motors 1 are connected respectively by shaft coupling with shaft 2.What needs to be explained here is that shaft coupling is matched with motor 1, shaft 2
The transmission that should be guaranteed that torque is closed, to realize the synchronous rotation of two motors 1.In other embodiments, as shown in Fig. 2, two
Motor 1 can also be connected directly by shaft coupling, the consistency of rotation both so as to ensure.
Further, the middle position of the shaft 2 is equipped with hub brake 3, can also realize the deceleration of pumping unit
With it is out of service.
Preferably, the motor 1 is fixedly mounted on by mounting bracket 4 on pedestal A.Mounting bracket 4 by motor 1 reliablely and stablely
On pedestal A, the axle center height of motor 1 is adjusted by adjusting mounting bracket 4 during use, is allowed to and pedestal A, crank B phases
Symbol, so as to can guarantee the reliability of pumping unit work.
