Sucker rod is driven to pump.
Preferably, the depending portion of the polished rod eye is located at the longitudinal center of pylon.
The pylon is that four root posts enclose the rectangular structure to be formed, and horizontal web member, phase are connected between adjacent upright posts
The diagonal web member of the setting that intersects is provided between adjacent level web member on adjacent column.
This pylon structure is that the welded standard knot of square steel is connected by bolts and forms, and it highly can be according to oil
Field actual condition and the requirement to oil pumper stroke are adjusted, and the structure can largely reduce the occupation of land for pushing away oil machine
Area and be particularly well-suited to long stroke or ultra-long-stroke and clump formula oil well mining operations pylons mainly use material for
The square steel of Q235A steel is welded.
The tower top is equipped with overhead traveling crane resigning mechanism, and overhead traveling crane resigning mechanism includes being arranged on the horizontal web member of tower top
Two toothed racks, overhead traveling crane wheel shaft two ends are machined with shaft head gear, and the shaft head gear at overhead traveling crane wheel shaft two ends is nibbled with two toothed racks respectively
Close, the position of the position adjustment overhead traveling crane by adjusting overhead traveling crane wheel shaft and two toothed racks.
When oil pumper needs to carry out workover treatment, the jackscrew of the tooth bar seat on girder is tightened, make tooth bar with peace
Mounted in crown sheave shaft head gear intermeshing can mobile overhead crane wheel, reach the purpose of resigning.
The counter weight device includes the balancing weight that several superpositions are set, and counterweight is adjusted by the quantity for adjusting balancing weight.
The operation principle of swing arm reversing arrangement：
During cylinder horizontal drive is converted into supporting plate vertical ascent, supporting plate has lifted counter weight device, realizes Gao Cheng
Carry, and complete the transformation of cylinder thrust size, direction and stroke.The swing arm of the device is distinguished with the connection end of supporting plate and connecting rod
It is large and small end, large and small end length lever ratio realizes the amplification of cylinder thrust；Swing arm swings and realizes cylinder thrust transmission side
To change；What swing arm pivot angle realized supporting plate lifts micro travel, it is often more important that the swing arm shaped angles of the device with swing
After angle coupling, swing arm is located at directly over rotating shaft with the contact position of supporting plate, and supporting plate is directly carried on rotating shaft, not by cylinder driving force
Size is limited, and elastic bearing is converted into non-yielding prop, substantially increases the load for lifting carrying.
The application has the following technical effect that using after said structure：
One kind, including pylon, be provided with pylon cylinder and
The swing arm reversing arrangement of air cylinder driven, it is possible to achieve high-mechanic, can be by adjusting the parameter and design of cylinder
