Description
Technical field
The utility model relates to a kind of beam type oil pumping machine crank weight adjusting device that oil field uses, and belongs to petroleum drilling and mining equipment field.
Background technology
At present, crankshaft balance weight formula oil pumper is still widely used in oil field, after oil pumper is in steady operation, the stressed size and Orientation due to up-down stroke horse head is change, so there is unbalanced problem, after suitable balance weight being installed according to operating mode, imbalance problem can obtain improvement to a certain extent, but brings following problem, and one is be plucked out of along with oily, operating mode also changes thereupon, and the position of balance weight likely needs to adjust; Second is after oil pumper stops when needing again to start, usually fluid column is not had due in now sucker rod, different when load suffered by oil pumper and steady operation, if direct disposable startup can bring impact to oil pumper, so can affect its application life for a long time, and the position first adjusting balance weight sometimes can be adopted to start this, when oil pumper start fuel-displaced after, then balance weight is adjusted to the position required for operating mode; 3rd is in the installation process of oil pumper, and when also not installing sucker rod, oil pumper is in non-equilibrium state, if think, direct rotating crank is very difficult.Above Railway Project all relates to the mobile adjustment of balance weight, and the adjustment existence operation of current conventional beam-pumping unit crankshaft balance weight is convenient not, and safety is not very high problem.Therefore, easy to operate, safe, laborsaving, fast weight adjusting device have certain application demand.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of beam type oil pumping machine crank weight adjusting device, and convenient not to solve above-mentioned crankshaft balance weight adjustment existence operation, safety is not very high problem.
The technical solution of the utility model is achieved in the following ways:
A kind of beam type oil pumping machine crank weight adjusting device of the utility model, primarily of balance weight, leading screw, the gap nut that disappears, guide wheel, guide rail, roller gear, conical gear, cylinder conical gear, handle, spline form.Balance weight and two gap nuts that disappear are connected, and two gap nuts that disappear connect with two rhizoid thick sticks respectively, and the two ends of two rhizoid thick sticks are arranged on the leading screw bearing on crank; Described balance weight to be rolled with the guide rail on crank by guide wheel and coordinates, and two roller gears are arranged on two rhizoid thick sticks respectively; Roller gear engages with the roller gear part of the cylinder conical gear be arranged on crank, and the conical gear sections of described cylinder conical gear engages with the conical gear be arranged on crank; Bevel pinion shaft be provided with for artificial hand operation handle and for coordinating the spline connected with electric wrench.
Described supporting seat has four, is arranged on the two ends of two rhizoid thick sticks respectively, and the inside of described supporting seat is provided with a thrust bearing and a deep groove ball bearing.
The utility model has the advantages that: the position 1, being regulated oil pumping machine crank balance weight by electric wrench or the mode of rotating manually.2, moment is converted into the lifting force to balance weight, utilizes the position of the self-locking character stable equilibrium block of leading screw, can ensure that balance weight is in desired location more accurately.3, this adjusting device can make balance weight positional structure simple, and manufacture with easy for installation, reliability is high, operates safe, laborsaving.

Detailed description of the invention
The utility model relates to a kind of beam type oil pumping machine crank weight adjusting device, and primarily of balance weight 5, leading screw 3, the gap nut 7 that disappears, guide wheel 6, guide rail 4, roller gear 8, conical gear 10, cylinder conical gear 9, handle 12, spline 11 form.Balance weight 5 and two gap nuts 7 that disappear are connected, and two gap nuts 7 that disappear connect with two rhizoid thick sticks 3 respectively, and the two ends of two rhizoid thick sticks 3 are supported by the leading screw bearing 2 be arranged on crank 1; Described balance weight 5 is rolled with the guide rail 4 on crank 1 by guide wheel 6 and coordinates, two roller gears 8 are arranged on two rhizoid thick sticks 3 respectively, roller gear 8 engages with the roller gear part of the cylinder conical gear 9 be arranged on crank 1, the conical gear sections of described cylinder conical gear 9 engages with the conical gear 10 be arranged on crank 1, bevel pinion shaft 13 be provided with for artificial hand operation handle 12 and for coordinating the spline 11 connected with electric wrench.
Operating principle of the present utility model: stopped tightly by beam pumping unit, during brake, the position of crank is determined by need of work, is generally at horizontal level, cuts off the electricity supply.Go out the position of required balance weight according to condition calculating, if adopt electric wrench to regulate, then the sleeve of electric wrench is inserted the keyway that crank coordinates with it.After starting electric wrench, according to the principle of similar jackscrew, moment of torsion is delivered to two rhizoid thick sticks by gear train by electric wrench simultaneously, make their rotating Vortexes, torque axis is changed into the lifting force to balance weight by two screw-nut bodies again, the rotation of electric wrench converts the rectilinear movement of balance weight to, and the rotation direction of electric wrench determines that balance weight moves up or moves down, and the velocity of rotation of electric wrench determines the speed of balance weight movement.Arrive after assigned address, shut down by electric wrench and take off, because feed screw nut can self-locking, balance weight is by the position of stopping after the adjustment.The crank of opposite side regulates in the same way.Owing to have employed the gap nut that disappears, crank balance weight when motion does not have movable situation and occurs, avoids and occurs that the collision because thin tail sheep causes occurs in the course of the work for leading screw and nut.Mode according to hand rotation regulates, and principle is identical with above-mentioned, but is with artificial hand replacement electric wrench.
