Description

The balance adjustment mechanism of beam pumping unit

Technical field

It the utility model is related to oil recovery field, more particularly to the technology of the balance weight of regulation oil pumper.

Background technology

During oil pump running, thereon, the load of down stroke have differences, cause motor output current unstable, easily it is right The equipment such as motor are caused damage, therefore counter weight of beam unit is generally provided with oil pumper, by often adjusting balance of well pumping unit The position of block, reach the purpose of the load of the upper and lower stroke of balanced oil extractor.

Oil well balancing is dynamic, is often operated in production, and the specific purpose tool that oil pumper is equipped with is crank, uses crank There must be operating platform, only be used in troop training, oil pumper scene is to meet.

The main tool of live mobile balanced block is crowbar；Small power is inadequate, and big operating space is larger, and people is necessary Stand on crank side, use the unsafe factor of crowbar balancing：

1st, underfooting, which has mud easily to skid, certain danger；

2nd, because crank tooth has certain taper, crowbar easily skids, and it is out of control that center of gravity easily occurs in people；

3rd, crowbar misoperation easily damages crank tooth；

4th, people easily produces dizziness on the overhead oil pumper in lake region；

5th, also have be balance weight not on crank tooth, people does not stand place；

6th, the safety belt of operating personnel is fixed without suitable place.

The content of the invention

The purpose of this utility model is for overcome the deficiencies in the prior art, there is provided a kind of safe and reliable beam type oil pumping The balance adjustment mechanism of machine.

What the purpose of this utility model was realized in：The balance adjustment mechanism of beam pumping unit, including crank peace Weigh block, crank pit is set on crank, crank pit includes crank notch and crank pit bottom, and the width of crank notch is less than The width of crank pit bottom；The balance adjustment mechanism also includes fixed seat and split hydraulic jack；The fixed seat includes Overhead gage, middle connecting plate and the lower position block being sequentially connected from top to bottom, the overhead gage are arranged on the top of crank, middle Connecting plate is arranged on crank notch, and lower position block is arranged on crank pit bottom；Peace is wholely set on the middle connecting plate Loading board, installing plate are arranged at crank notch, in block teeth of the side of the installing plate welding with latch, the opposite side of installing plate Connect fastening screw, fastening screw threaded connection nut, the latch and nut of block teeth respectively with crank notch width Both sides are fixed；The split hydraulic jack includes hydraulic jack and hydraulic control device, and hydraulic jack is arranged on balance Between block and fixed seat, hydraulic control device rest on the ground and is connected by oil pipe with hydraulic jack.

The utility model adds a split hydraulic jack between fixed seat and crank, and such operating personnel can on ground With mobile balanced block, unsafe factor dangerous caused by background technology is avoided.Produced backward by being installed in fixed seat The block teeth of moving resistance, block teeth and the inner side of crank pit two are supported using the turn clockwise principle of elongation of fastening screw and nut Face, rotational fastener screw fix block teeth and crank medial surface tensioner.

To back pressure overhead gage can be made crooked backward using caused by jack, lower edge and the crank notch of overhead gage The top edge contact of the crank at place, the top edge of lower position block are contacted with the lower edge of the crank at crank notch, and generation is suppressed Strength eliminates most of power acted in fixed seat, and such balance weight just moves forward in the presence of jack.

The utility model has the characteristics that：1st, handling ease, quick and easy for installation, has a safety feature；2nd, people is on ground Can easily mobile balanced block；3rd, fixed mount be may be mounted at from anywhere in crank pit, it is possible to achieve long and short distance is moved Dynamic crank；4th, it is not tight to stop level angle requirement of the oil pumper to crank.

If balance weight is in the first and end of crank, the length of the distance between overhead gage and balance weight are insufficient jack, Hole, screwed hole internal thread connection fine-tuning screw are threaded on the overhead gage.Utilize the box on overhead gage and supporting Fine-tuning screw coordinates, and fine-tuning screw heads on balance weight and can also move a certain distance balance weight, after use jack again.If take out The balanced ratio and standard of oil machine are more or less the same, balance weight short-distance movement, and fine-tuning screw can is realized.

In order to which fixed seat is turned over and stuck up when preventing rotational fastener screw, turnover panel, turnover panel are wholely set in the upper end of the installing plate Positioned at the upper surface of crank.
