Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, specifically a hydraulic support for a hydraulic pumping unit. Background Technology

[0002] In the field of oil extraction, pumping units are one of the key pieces of equipment for crude oil extraction. Their performance directly affects extraction efficiency, energy consumption, and operational stability. Hydraulic pumping units use hydraulic transmission as their core drive mechanism, converting hydraulic energy into mechanical energy through components such as hydraulic pumps and cylinders to achieve the reciprocating motion of the sucker rod. Compared with traditional beam pumping units, hydraulic pumping units have significant advantages such as low energy consumption, wide speed range, fast response speed, and compact structure. They can better adapt to the extraction needs of different oil wells, especially performing outstandingly in complex conditions such as heavy oil wells and deviated wells. Therefore, they are gradually becoming an important development direction for oil extraction equipment. In the overall structure of a hydraulic pumping unit, the hydraulic support is a key supporting component that ensures the stable operation of the equipment. Its main function is to provide a solid mounting foundation for the actuator of the hydraulic pumping unit.

[0003] In the existing technology, hydraulic supports for hydraulic pumping units mostly adopt rigid frame structures, which are fixed supports formed by welding or bolting. For different models of hydraulic pumping units or different installation conditions, supports of different sizes and structures need to be customized, which has poor versatility and increases production and maintenance costs. Therefore, a hydraulic support for hydraulic pumping units is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic support for a hydraulic pumping unit, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic support for a hydraulic pumping unit, comprising a base plate and four mounting plates. Two fixing blocks are fixedly connected to the top outer surface of the base plate, and a positive and negative lead screw is rotatably connected between the two fixing blocks. Two threaded plates are threadedly connected to the outer surface of the positive and negative lead screws. A T-shaped rod is fixedly connected to the top outer surface of the two threaded plates. Extension rods are movably inserted into the left and right outer surfaces of the T-shaped rod. Several positioning screw holes arranged in a linear array are opened on the outer surface of the extension rod. Positioning bolts are threaded through the left and right ends of the top outer surface of the T-shaped rod, and the other end of the positioning bolt is threaded into the internal thread of one of the positioning screw holes.

[0006] Furthermore, a connecting block is fixedly connected to the other end of the extension rod, a fixed rod is fixedly connected to the top outer surface of the connecting block, a movable rod is movably inserted into the inner surface of the fixed rod, a spring is fixedly connected inside the fixed rod, the other end of the spring is connected to the movable rod, and the four mounting plates are respectively fixedly connected to the top of the four movable rods.

[0007] Furthermore, two sliding rods are fixedly connected between the two fixed blocks, and the threaded plate is movably sleeved on the outer surface of the two sliding rods.

[0008] Furthermore, pulleys are installed on the bottom outer surfaces of both threaded plates, and the pulleys are in movable contact with the outer surface of the base plate.

[0009] Furthermore, a support rod is fixedly connected to the bottom outer surface of the connecting block, and a ball bearing is provided on the bottom outer surface of the support rod, the ball bearing being in movable contact with the surface of the base plate.

[0010] Furthermore, two side frames arranged symmetrically front to back are fixedly connected to the top outer surface of the base plate, and a cross plate is provided between the two side frames.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This hydraulic pumping unit uses a hydraulic support. By rotating the positive and negative screws, two threaded plates are moved to adjust the position between the two mounting holes on the front and rear sides. By unscrewing the positioning bolts, the positioning bolts are disengaged from the positioning screw holes, and the position between the two mounting holes on the left and right sides is adjusted. This allows for the installation of hydraulic cylinders of different sizes and models, and then the installation of other components.

[0013] The hydraulic pumping unit uses a hydraulic support. When the hydraulic pumping unit is working, the vibration force generated is transmitted to the movable rod, causing the spring to deform. The spring buffers the vibration force, and the friction between the movable rod and the fixed rod generates damping, which buffers the elastic force of the spring. The vibration can be further reduced by installing a damping shock absorber between the mounting plate and the connecting block. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to the following: Figures 1-3 This utility model provides a technical solution: a hydraulic support for a hydraulic pumping unit, comprising a base plate 1 and four mounting plates 9. Two fixing blocks 2 are fixedly connected to the top outer surface of the base plate 1. A positive and negative threaded rod 3 is rotatably connected between the two fixing blocks 2. Two threaded plates 4 are threadedly connected to the outer surface of the positive and negative threaded rod 3. T-shaped rods 5 are fixedly connected to the top outer surface of the two threaded plates 4. Extension rods 6 are movably inserted into the left and right outer surfaces of the T-shaped rod 5. Several positioning screw holes 7 arranged in a linear array are opened on the outer surface of the extension rod 6. Positioning bolts 8 are threaded through both ends of the top outer surface of the T-shaped rod 5. The other end of the positioning bolt 8 is threaded into the internal thread of one of the positioning screw holes 7. Specifically... Based on the position of the hydraulic cylinder mounting hole, adjust the position of the mounting waist hole 10 so that the mounting waist hole 10 corresponds to the position of the mounting hole. At this time, rotate the positive and negative screw 3. The rotation of the positive and negative screw 3 drives the threaded plate 4 to move. The threaded plate 4 drives the two T-shaped rods 5 to move, adjusting the position of the front and rear mounting waist holes 10. By unscrewing the positioning bolt 8, the positioning bolt 8 is disengaged from the inside of the positioning screw hole 7, releasing the limit between the T-shaped rod 5 and the extension rod 6. Adjust the position between the left and right mounting waist holes 10, thereby adjusting the multiple mounting waist holes 10 to the position corresponding to the hydraulic cylinder mounting hole. Then, install the hydraulic cylinder with bolts and screws, thus enabling the installation of hydraulic cylinders of different sizes and models.

[0020] In this embodiment, a connecting block 14 is fixedly connected to the other end of the extension rod 6. A fixed rod 11 is fixedly connected to the top outer surface of the connecting block 14. A movable rod 12 is movably inserted into the inner surface of the fixed rod 11. A spring 13 is fixedly connected inside the fixed rod 11. The other end of the spring 13 is connected to the movable rod 12. Four mounting plates 9 are fixedly connected to the top of the four movable rods 12 respectively. Specifically, when the hydraulic pumping unit vibrates during operation, the vibration force is transmitted to the movable rod 12, causing the movable rod 12 to move inside the fixed rod 11. The vibration force is buffered by the spring 13. Damping is generated by the friction between the movable rod 12 and the fixed rod 11, which buffers the elastic force of the spring 13. It is worth noting that damping shock absorbers can be added between the mounting plate 9 and the connecting block 14 to further reduce vibration, improve the damping effect, and prevent the spring 13 from vibrating continuously.

[0021] In this embodiment, two sliding rods are fixedly connected between the two fixed blocks 2, and the threaded plate 4 is movably sleeved on the outer surface of the two sliding rods. Specifically, when the positive and negative screws 3 rotate, they drive the threaded plate 4 to move, so that the threaded plate 4 slides on the outer surface of the two sliding rods, thus preventing the threaded plate 4 from rotating with the rotation of the positive and negative screws 3.

[0022] In this embodiment, pulleys 17 are installed on the bottom outer surfaces of both threaded plates 4. The pulleys 17 are in contact with the outer surface of the base plate 1. Specifically, when the threaded plates 4 move, the pulleys 17 slide on the base plate 1, and the bottom of the threaded plates 4 is supported by the pulleys 17, thereby increasing the strength of the bottom of the threaded plates 4.

[0023] In this embodiment, a support rod 15 is fixedly connected to the bottom outer surface of the connecting block 14, and a ball bearing 16 is provided on the bottom outer surface of the support rod 15. The ball bearing 16 is in movable contact with the surface of the base plate 1. Specifically, when the connecting block 14 moves, the bottom of the connecting block 14 is supported by the support rod 15 to prevent the bottom of the connecting block 14 from being suspended, thereby increasing the support strength of the connecting block 14. Furthermore, by providing the ball bearing 16, it is easy to make the support rod 15 move stably when it moves.

[0024] In this embodiment, two side frames 18 arranged symmetrically front and back are fixedly connected to the top outer surface of the base plate 1. A horizontal plate 19 is provided between the two side frames 18. Specifically, other components in the hydraulic pumping unit are installed by setting the horizontal plate 19, and by adding pipe slots and adjustable fixing buckles in appropriate positions, these components can neatly store hydraulic oil pipes, control cables, etc., and avoid friction and compression between pipes.

[0025] Working Principle: In use, this utility model adjusts the position of the mounting holes 10 according to the mounting hole position of the hydraulic cylinder, based on the different models of hydraulic cylinders, so that the mounting holes 10 correspond to the mounting holes. At this time, the positive and negative screws 3 are rotated, which drives the threaded plate 4 to move. The threaded plate 4 drives the two T-shaped rods 5 to move, adjusting the position of the front and rear mounting holes 10. By unscrewing the positioning bolts 8, the positioning bolts 8 are disengaged from the inside of the positioning screw holes 7, releasing the restriction between the T-shaped rods 5 and the extension rods 6. The position between the left and right mounting holes 10 is then adjusted, thereby adjusting the multiple mounting holes 10 to the corresponding positions of the hydraulic cylinder mounting holes. Then, the hydraulic cylinder is installed with bolts and screws, thus enabling the installation of hydraulic cylinders of different sizes and models, and then other components are installed.

[0026] When the hydraulic pumping unit vibrates during operation, the vibration force is transmitted to the movable rod 12, causing the movable rod 12 to move inside the fixed rod 11. The vibration force is buffered by the spring 13. The friction between the movable rod 12 and the fixed rod 11 generates damping, which buffers the elastic force of the spring 13. The vibration can be further reduced by installing a damping shock absorber between the mounting plate 9 and the connecting block 14.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
