Description

The utility model relates to installations designed for oil production by deep-well sucker rod pumps.

Known rocking machine (a. St. USSR No. 682668, authors Kiselev N.G. et al., Publ. 30.08.79, bull. No. 32) mounted on a foundation and containing a frame with an arrow, a rack, a balancer, a rope suspension , the head of the balancer with a roller unit for mounting the cable suspension, and an additional rack mounted on the foundation, interacting with the boom and having an axis on which the pulley is mounted.

The disadvantage of this rocking machine is the significant size and complexity of the design due to the presence of a frame with an arrow and an additional rack.

A rocking machine is also known (Fig. 4.21, p. 151, book by S. L. Nikishenko, “Oilfield Equipment”, published by “IN-Folio”, Volgograd - 2008), containing a frame, a rack, a balancer, a balancer head and a rope suspension. The disadvantage of the above rocking machine is that during operation it tilts away from the original vertical position.

The purpose of the utility model is to increase the operability of the rocking machine.

This goal is achieved by the fact that in a rocking machine containing a frame, a rack, a balancer, a balancer head and a rope suspension, the frame is mounted on at least four piles, which are pipes fixedly fixed by the upper ends by welding to the frame, while the lower ends pipes are located in the ground below the freezing depth of the soil, and at the lower ends of the pipes screw blades are fixed to the side walls, and the internal cavities of the pipes are filled with cement-sand mortar or bitumen, and at the lower ends of each pipe with t The holes are made of the same size of the openings in the form of an isosceles triangle, and the axis of symmetry of the isosceles triangle is parallel to the axis of the pipe, and the petals in the form of triangles formed by the openings are bent to the axis of the pipe, and the edges of the petals adjacent to each other are connected by welding.

In FIG. 1 schematically shows a General view of the rocking machine; in FIG. 2 shows the lower end of the pipe blank; in FIG. 3 is a section AA of FIG. 2.

The rocking machine contains a frame 1 (Fig. 1), a rack 2, a balancer 3, a head of a balancer 4 and a rope suspension 5. Frame 1 is installed on at least four piles 6. They

are pipes 7, fixedly fixed by the upper ends 8 by welding to the frame 1. The lower ends 9 of the pipes 7 are located in the ground below the depth of freezing of the soil. At the lower ends 9 of the pipes 7, screw blades are fixed to the side walls 10. At the lower ends 9 of each pipe 7, the openings 11 of the same size are made from the end face (Fig. 1) in the shape of an isosceles triangle. The axis of symmetry 12 of the isosceles triangle is parallel to the axis of the pipe 7. The petals 13 in the form of triangles formed by the openings 11 are bent to the axis of the pipe 7. The ribs 14 of the petals 13 adjacent to each other are connected by welding. In another embodiment, the internal cavities of the pipes 7 are filled with cement-sand mortar or bitumen.

The principle of operation of the rocking machine is as follows. When operating the rocking machine, frame 1 receives inertial forces from turning the head of the balancer 4 and the balancer 3 clockwise and counterclockwise. The frame 1 also receives gravitational forces from the mass of the rack 2, the head of the balancer 4 and the balancer 3. Still on the frame 1 are variable forces from the movement of the cable suspension 5 (since it connects to the deep pump). These forces are transmitted from the frame 1 to the pipes 7, the lower ends 9 of which are located in the ground below the freezing depth of the soil. This prevents the axial movement of the pipes 7 in the ground in the summer, when the soil thaws. Screw blades 10 also prevent the axial movement of the pipes 7 from the action of the above efforts. Bent petals with ribs welded to each other prevent the penetration of soil into the pipe cavity 7. A cement-sand mortar or bitumen filled into the pipe cavity 7 protects the inner wall of the pipes 7 from corrosion.

In the proposed rocking machine in comparison with the prototype significantly improves performance. Due to the installation of the frame on piles of pipes with helical blades and the location of the lower ends of the pipes in the ground below the freezing depth of the soil, the frame of the proposed rocking machine does not tilt from its original position. In the prototype, due to inertial and gravitational forces, the rocking machine tilts from the original horizontal plane. This violates the plane of the frame relative to the horizontal above the permissible (passport) deviations and the rocking machine is stopped for repair.
