Abstract
The utility model relates to a jack-type pumping unit balancing tool. The jack-type pumping unit balancing tool is characterized by mainly comprising a jack, a fixing support, a pin rod and a wrench. The fixing support is fixed on a crank, the jack is fixed on the fixing support, a free end of the jack is hinged to one end of the wrench through the pin rod, and the other end of the wrench is provided with a hole which can sleeve a balancing block fixing screw. The wrench can drive the balancing block fixing screw to rotate along with expansion of the jack. When the jack-type pumping unit balancing tool is in operation, a wedge is wedged under a balancing block to raise the balancing block, the jack can be used to move the balancing block to a required position easily without demounting a balancing block tiger claw screw, the jack can be used with the wrench to stably move the balancing block to the required position when the balancing block fixing screw is demounted, and accordingly the defects of no operating space and unsafety are overcome, the jack-type pumping unit balancing tool is safer and quicker and required manpower is reduced.
Description
Technical field
The utility model relates to a kind of instrument of adjusting the balance of well pumping unit rate, is a kind of instrument that can unload screw, mobile balanced block concretely.
Technical background
Beam pumping unit is a kind of capital equipment in the field produces, and the beam pumping unit well accounts for more than 95% of machine-pumped oil well.The work characteristics of oil pumper is to bear stress alternation.For even running, oil pumper must adopt bascule, and owing to the reasons such as dynamic adjustment of the working condition of formation condition, down-hole pipe equipment and oil well operation, manufacturing parameter, tends to destroy the original equilibrium state of oil pumper.Oil pumper turns round under unbalanced state, can have a strong impact on the surface efficiency of pumpingh well, shorten the application life of motor and reduction box, worsen the working condition of sucker rod, so that the rod parting number of times obviously increases, therefore just must often adjust balance of well pumping unit.
At present, the balancing mode that adopt in the oil field is to utilize traditional instrument crank or crowbar to finish the work, but works under the adverse circumstances at the long-term place out of office of oil pumper, and screw corrosion dismounting difficulty is difficult for having an effect, and balance weight moves difficulty.The time that operates like this is long, and safety is not high, simultaneously, because some oil wells easily shakes out, easy frozen pipe line, stops can directly cause the operation of sand card or pipeline frozen block after the well time length, causes huge economic loss to enterprise.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the prior art deficiency, and a kind of jack type balancing tool for oil pumping machine of quickly and easily mobile balanced block is provided.
The utility model is for solving the problems of the technologies described above by the following technical solutions: a kind of jack type balancing tool for oil pumping machine is characterized in that: mainly comprise jack, fixed support, pin rod, wrench; Fixed support is fixed on the crank, and jack is fixedly supported on the fixed support, and the free end of jack is hinged by an end of pin rod and spanner, and the other end of spanner is provided with the hole that can entangle the balance weight fixed screw; Described spanner can rotate along with the telescopic band dynamic balance weight fixed screw of jack.
By technique scheme, fixed support is fixed in the T-slot on the crank under the balance weight by T shape fixed screw.
By technique scheme, described instrument also comprises the wedge for mobile balanced block; Wedge is that nearly 90 degree angle L-types are tabular, and an end plate and the balance weight base under the balance weight fixed screw of wedge are contour, and the other end is the ramped shaped plate, by the past gradually attenuation of outer end of L-type binding site; A described end plate offsets with the jack free end and contacts and can move with jack, and described ramped shaped plate is positioned between balance weight and the crank and can moving therein.
By technique scheme, the ramped shaped plate of wedge is between the brave pawl anti-slop serrations and crank face anti-slop serrations of balance weight lower surface.
The utility model is when operation, can first fixed support be fixed in the T-shaped groove on the crank, and wedge wedged under the balance weight, with the balance weight bed hedgehopping, like this, in the situation that need not dismantle balance weight tiger screw claw, just can utilize easily jack that balance weight is moved to needed position, simultaneously, when dismounting balance weight fixed screw, utilize jack to cooperate with wrench, can stably balance weight be moved to needed position, in the course of the work, having overcome does not have the operating space, unsafe defective, safer with respect to traditional method of operating, fast, required manpower also still less.Compared with the prior art, it is more steady to operate, safety, and the danger of falling from high altitude can not appear in the dismounting screw, and mobile balanced block is also steadily shockproof, brake slide car casualty accident can not occur.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of jack type balancing tool for oil pumping machine shown in Fig. 1-2 mainly comprises jackscrew 5, fixed support 6, wedge 9, wrench 3 four parts; In the T-slot that fixed support 6 is designed to be fixed on the crank 8 with T shape fixed screw 7, provide support power for jack 5, jackscrew 5 is connected on the fixed support 6, and free end is hinged by pin rod 4 and spanner 3.
Wrench 3 afterbodys have a circular hole, and an end penetrates in the circular hole on the pin rod 4, and an end is enclosed within jack 5 heads, is used.
Wedge 9 is that nearly 90 degree angle L-types are tabular, and an end is thicker be thrust plate, and the other end is positioned between balance weight 1 and the crank 8 when promotion balance weight 1.
Among the embodiment of Fig. 1-2, in dismounting balance weight fixed screw 2 processes, during dismounting balance weight fixed screw 2, be used in combination with jack 5, fixed support 6, wrench 3.In the T-slot that first fixed mount 6 usefulness T shape set bolts 7 is fixed on the crank 8, jack 5 is placed on the fixed mount 6, spanner 3 is enclosed within on the balance weight fixed screw 2, then with pin rod 4 two parts are connected, shape has a certain degree, and the strength that just can utilize jack 5 to produce loosens bolt.
Among Fig. 3 embodiment, screw 2 is loosening after, when mobile balanced block 1, be used in combination with jack 5, fixed support 6 and wedge 9.In the T-slot that first fixed mount 6 usefulness T shape set bolts 7 is fixed on the crank 8, between wedge 9 wedging balance weights 1 and crank 8, brave pawl anti-slop serrations 10 and crank face anti-slop serrations 11 are thrown off, then utilize jack 5 just can easily balance weight 1 be moved to needed position.
