The utility model has the characteristics of the practicality is strong, the location is accurate, the commonality is good, safety and stability etc, be particularly useful for the beam -pumping unit's of three landing legs manufacturing, have the fine value of using widely in this series beam -pumping unit's use.
Description
Technical field
The utility model relates to oil development oil recovery machiner field, is specifically related to a kind of secure localization protective equipment of beam pumping unit.
Background technique
Beam pumping unit is that oil field development uses pumping unit more widely, and its structure is shown in Fig. 1; At present in the production and application process of pumping unit, Framework of Pumping Unit is because the particularity of its welding processing, and cause the bad control of accurate to dimension error of support, interchangeability is relatively low; The support of suitable installation can greatly improve the overall performance of pumping unit and reduce power loss; Pumping unit works for a long time in the wild in addition, and operating environment is relatively severe, and Framework of Pumping Unit each joint bolt easily loosens, corrosion, and such as Framework of Pumping Unit back leg generation skew causes contingency to occur.
Model utility content
The purpose of this utility model is exactly the defect existed for prior art, provides that a kind of structure is simple, accurate positioning, easy to adjust, versatility good and Framework of Pumping Unit back leg positioning protection device easy to process.
The concrete technological scheme of the utility model is: comprise the positioning block be fixed on square chest and the support back leg base plate be movably arranged on square chest, and described support back leg base plate and the forward and backward interval arranged side by side of positioning block are arranged; Described positioning block is provided with multiple interior threaded holes of or lateral separation arrangement, all by screw-thread fit mounting and adjusting bolt in described interior threaded hole, after described adjustment bolt-through positioning block front end and support back leg base plate against, described adjustment bolt rear end is set with can by its tightening nut of locking relative to positioning block.
Such scheme is more preferably:
Preferably, described positioning block is welded on square chest, and described support back leg base plate is arranged on square chest by holding down bolt, guarantees that positioning block and support back leg base plate are fixed firm.
Preferably, the length of described adjustment bolt can adjust, and namely adjustment range according to actual needs can select the adjustment bolt of appropriate length.
Preferably, described positioning block, tightening nut and adjustment bolt are through heat treated workpiece, to ensure enough intensity, can meet field extreme environment and working condition requirement.
The utility model has the features such as practical, accurate positioning, versatility are good, safety and stability, is particularly useful for the manufacturing of the beam pumping unit of three supporting legs, has good popularizing value in the using process of this serial beam pumping unit.
Accompanying drawing explanation
Fig. 1 is the structural representation of beam pumping unit;
Fig. 2 is structural representation of the present utility model (the A portion enlarged view namely in Fig. 1);
Fig. 3 is the side view of positioning block in Fig. 2.
In figure: 1, square chest, 2, positioning block, 3, support back leg base plate, 4, support back leg, 5, adjustment bolt, 6, tightening nut, 7, setscrew nut, 8, support foreleg.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 2-3, a kind of Framework of Pumping Unit back leg positioning protection device, comprises the positioning block 2 be welded on square chest 1 and the support back leg base plate 3 be arranged on by setscrew nut 7 on square chest 1, and support back leg base plate 3 and positioning block 2 forward and backward interval arranged side by side are arranged; Positioning block 2 is provided with two interior threaded holes of lateral separation arrangement, all by screw-thread fit mounting and adjusting bolt 5 in interior threaded hole, adjustment bolt 5 to run through after positioning block 2 front end and support back leg base plate 3 against, adjusting that bolt 5 rear end is set with can by its tightening nut 6 of locking relative to positioning block 2.
Adjustment bolt can directly be bought by market or adopt machine tooling to form.According to the length of adjustment and the mounting point on square chest during use, rationally determine bolt length, and it is fixed on square chest by positioning block; According to the distance of support back leg floor and positioning block, by changing the length leaning out positioning block outside adjustment bolt, thus the position of support back leg base plate is moved, thus drives the fixed position changing support back leg; And locked with locking nut, and ensure the fixing of adjustment bolt position, ensure the precision of support back leg assembling; Simultaneously also prevent from equipment in use because the link of support back leg is insecure then to move, thus the accident causing whole equipment to damage phenomenon occurs; In addition, by adjustment bolt length, slightly can change the angle of inclination of support back leg, avoid the generation affecting overall performance phenomenon because the processing of support back leg angle is inaccurate to a certain extent.
This positioning protection device adopts threaded adjusting position location, and structure is simple, and accurate positioning is convenient and swift; Adjusting bolt adopts Tempering and Quenching, adds its intensity and antiwear property, safeguards simple and convenient; This positioning protection device does not need to do larger change on pumping unit, but adds that this device can improve the overall performance of pumping unit greatly, easily promotes, practical; This device is suitable for three leg support formula pumping units of various model.
For those skilled in the art, under the prerequisite not departing from the utility model principle, likely to concrete size, or partial structurtes make some improvements and modifications, and these improvements and modifications also should be considered as protection domain of the present utility model.
