Person includes being more than two groups of support beams 61, without being confined to two groups of support beams 61, to provide stable support to hydraulic cylinder 2.Moreover,
The triangular structure that two groups of support beams 61 are formed is without the form being confined to shown in Fig. 2 or the three of other forms
Angular structure, as long as hydraulic cylinder 2 can be given to provide stable support.In addition, hydraulic oil pumping unit not necessarily sets hydraulic pressure
Cylinder support member 6, such as relatively strong, the relatively stable hydraulic cylinder 2 of structure, hydraulic cylinder support member 6 can be not provided with, utilize hydraulic cylinder
2 itself intensity and be stably fixed on base 1.
In certain embodiments, piston rod 21 is internally provided with the dynamic curve for continuously detecting piston rod 21 at it
Sensor (not shown).By setting such sensor, it can not only detect that piston rod 21 moves to hydraulic cylinder 2 and pushed up
Situation when portion and bottom, situation of the piston rod 21 at the centre position of hydraulic cylinder 2 can also be detected.Work can thus be provided
The whole continuous dynamic curve of the motion in hydraulic cylinder 2 of stopper rod 21, is easy to judge the whether smooth operation of hydraulic cylinder 2.This species
The sensor of type, and be configured with this type sensor hydraulic cylinder 2 it is commercially available, therefore to its working method and operation principle
Repeat no more.
In certain embodiments, as shown in figure 1, hydraulic oil pumping unit also includes hydraulic power station 8, hydraulic power station 8 is logical
The rodless cavity room that a fluid pressure line 81 is crossed with the bottom positioned at hydraulic cylinder 2 is connected.Hydraulic power station 8 is that hydraulic cylinder 2 provides height
Pressure oil, high pressure oil are transported to the rodless cavity room of the bottom of hydraulic cylinder 2 by fluid pressure line 81, to produce thrust by piston rod 21
Boost upwards.When hydraulic power station 8 no longer provides high pressure oil, piston rod 21 can be declined by Action of Gravity Field.Certainly, ability
Field technique personnel, which should be appreciated that, can also use two fluid pressure lines 81 to connect respectively with the bottom of hydraulic cylinder 2 and the chamber on top
Connect.So, the high pressure oil that the up and down motion of the piston rod 21 of hydraulic cylinder 2 is conveyed by two fluid pressure lines 81 respectively is realized.
In certain embodiments, as depicted in figs. 1 and 2, hydraulic cylinder 2 is arranged at base 1 close to the side of oil well 5.Or
Hydraulic cylinder 2 is arranged at base 1 close to the edge of oil well 5.So, distance of the hydraulic cylinder 2 away from oil well 5 be substantially equal to base 1 away from
The distance of oil well 5.When sucker rod connector 52 is aligned with oil well 5, distance of the hydraulic cylinder 2 away from oil well 5 is hydraulic cylinder 2 with taking out
The distance of beam hanger connector 52, and this distance depends on the length of moving pulley bracket 31.In other words, hydraulic cylinder 2 is arranged at
When base 1 is close to the edge of oil well 5, distance of the base 1 away from oil well 5 is farthest.Enough spaces can be thus reserved to oil well 5,
Such as oil well 5 can be repaired without oil pumper is removed.Certainly, when the length of moving pulley bracket 31 is larger,
I.e., it is sufficient to when reserving enough spaces to oil well 5, then hydraulic cylinder 2 may be not necessarily provided at base 1 close to the edge of oil well 5, or
Person is arranged on base 1 close to the side of oil well 5, the other positions that can also be arranged on base 1.But moving pulley bracket 31
Length it is longer, the stability requirement to hydraulic cylinder 2 is higher.
In real work, when hydraulic cylinder 2 is acted on by high pressure oil, piston rod 21 moves upwards, is fixed on piston
The also motion upwards of the movable pulley component 3 of bar 21.Across movable pulley component 3 hawser 4 due to being fixed on base 1 in one end, with dynamic
The upward motion of pulley assembly 3, the other end of hawser 4 also move upwards, so as to be connected to the connection of the sucker rod of the other end of hawser 4
The also motion upwards of device 52.As shown in Figure 3, it is shown that be in most according to the hydraulic oil pumping unit of one embodiment of the present utility model
Floor map during big stroke.When hydraulic cylinder 2 is no longer influenced by high pressure oil effect, due to Action of Gravity Field, piston rod 21 connects
Moved downward with the movable pulley component 3 being fixed thereon.The sucker rod connector 52 for being connected to the other end of hawser 4 is also downward therewith
Motion.Therefore, by the up and down motion of the piston rod 21 of hydraulic cylinder 2, the up and down motion of sucker rod connector 52 is realized, and then
Realize oil pumping operation.
In each embodiment described above, pass through and the movable pulley component with two groups of movable pulleies be set so that base with
The half of the distance length about the same in moving pulley bracket of oil well, ensure that base and oil well have larger distance, so both
The installation of hydraulic oil pumping unit can be facilitated, and can facilitate and oil well is repaired.Further, since the bottom of hydraulic cylinder 2
Base 1 is fixed in portion, and the height of hydraulic oil pumping unit is relatively low, there is preferable stability.As a result of movable pulley component 3, liquid
The stroke of the piston rod 21 of cylinder pressure 2 is the half of the stroke of sucker rod connector 52.That is, the piston rod 21 of hydraulic cylinder 2
The distance of up and down motion is the half of the up and down motion distance of sucker rod connector 52.This can effectively extend the use of hydraulic cylinder 2
Life-span.Further, since hydraulic cylinder 2 is located at the side of oil well 5, the maintenance of oil well 5 can be carried out relative to hydraulic cylinder 2 is independent, nothing
Mobile hydraulic cylinder 2 is needed, interferes with sucker rod 51 so piston rod 21 will not occur and needs to block or extend the feelings of sucker rod 51
Condition.
Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
This is merely illustrative of, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
On the premise of without departing substantially from principle of the present utility model and essence, various changes or modifications can be made to these embodiments,
But these changes and modification each fall within the scope of protection of the utility model.
