Abstract
The utility model discloses an adjustable oil pumping unit balance block moving device which comprises an oil pumping unit crank, a support bolt, a support block, a hydraulic press, a nut, a screw, a balance block fixing bolt and an oil pumping unit balance block, wherein the oil pumping unit balance block is mounted on the oil pumping unit crank; the oil pumping unit balance block and the oil pumping unit crank are connected through the balance block fixing bolt; the support block is fixed on the oil pumping unit crank by the support bolt; the hydraulic press, the nut and the screw are arranged between the support block and the oil pumping unit balance block; an internal thread of the nut and an external thread of the screw are screwed up; the left end of the nut leans on the hydraulic press; the right end of the screw pushes against the oil pumping unit balance block; the screw length can be adjusted, and the moving distance of the oil pumping unit balance block can be increased; the oil pumping unit balance block is easy to move without lots of time or great force, the labor intensity of the operation workers is low; danger is avoided in operation; and by adopting the adjustable oil pumping unit balance block moving device, the oil pumping unit balance block can be conveniently and quickly moved to a required position, and the shutdown time of the oil pumping unit is short.
Description
Technical field
The utility model is the device of using on a kind of oil-field oil pumper, is a kind of adjustable balance of well pumping unit piece mobile device.
Background technology
The balance weight of oil pumper needs often adjustment position; Balance requirement in the time of could satisfying the upper and lower stroke of oil pumper; The position of adjustment balance weight needs the balance weight of several tons of weights is moved to the another one position, and the method for present on-the-spot mobile balanced block is to unload loose balance weight fixed screw earlier; Prize balance weight with crowbar again, fastening again balance weight fixed screw.Because balance weight has several tons of weights, therefore, prize very slow, effort, the operator is dangerous big, causes personal injury easily, and the shutdown of pumping machine time is long, and the load affair is produced, and influences oil well output.
Summary of the invention
The purpose of the utility model is a kind of adjustable balance of well pumping unit piece mobile device of design, utilizes this adjustable balance of well pumping unit piece mobile device, can easily and efficiently the balance of well pumping unit piece be moved to the position that needs.
The purpose of the utility model is achieved in that and comprises oil pumping machine crank, carrying bolt, back-up block, hydraulic press, nut, screw rod, balance weight set bolt, balance of well pumping unit piece; The balance of well pumping unit piece is installed on the oil pumping machine crank; The balance of well pumping unit piece is connected by the balance weight set bolt with oil pumping machine crank; Back-up block is fixed on the oil pumping machine crank by carrying bolt, lays hydraulic press, nut, screw rod between back-up block and the balance of well pumping unit piece, and the internal thread of nut and screw rod external screw thread screw; The nut left end is close to hydraulic press, and the screw rod right-hand member withstands the balance of well pumping unit piece.
The beneficial effect of the utility model is: nut, screw rod are arranged, and rotary screw can adjusting screw(rod) length, can increase the displacement of balance of well pumping unit piece; The operation hydraulic press is ability mobile diesel engine balance weight just, and hydraulic press has the effect of reinforcement, and therefore, the mobile diesel engine balance weight is time saving and energy saving; Time saving and energy saving, operator's labour intensity is low, is safe from danger during operation; Utilize this adjustable balance of well pumping unit piece mobile device, can easily and efficiently the balance of well pumping unit piece be moved to the position that needs, do not influence job schedule; The shutdown of pumping machine time is short, and the load affair production time is short, has reduced the oil well output because of the balancing influence.
Description of drawings
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with Fig. 1 the embodiment of the utility model is described.
Can know by figure; The embodiment of the utility model comprises oil pumping machine crank 1, carrying bolt 2, back-up block 3, hydraulic press 4, nut 5, screw rod 6, balance weight set bolt 7, balance of well pumping unit piece 8; Balance of well pumping unit piece 8 is installed on the oil pumping machine crank 1, and balance of well pumping unit piece 8 is connected by balance weight set bolt 7 with oil pumping machine crank 1, and back-up block 3 is fixed on the oil pumping machine crank 1 by carrying bolt 2; Lay hydraulic press 4, nut 5, screw rod 6 between back-up block 3 and the balance of well pumping unit piece 8; The internal thread of nut 5 and screw rod 6 external screw threads screw, and nut 5 left ends are close to hydraulic press 4, and screw rod 6 right-hand members withstand balance of well pumping unit piece 8.
During use, install carrying bolt 2, back-up block 3, hydraulic press 4, nut 5, screw rod 6 earlier, after unclamp balance weight set bolt 7; Primer fluid press 4, the thrust that hydraulic press 4 produces moves balance of well pumping unit piece 8 on balance of well pumping unit piece 8; After hydraulic press 4 strokes finish, hydraulic press 4 is resetted, rotary screw 6; Make screw rod 6 right-hand members withstand balance of well pumping unit piece 8 once more, restart hydraulic press 4, balance of well pumping unit piece 8 is moved to the position that needs.
