Description

Technical Field

[0001] The utility model relates to the technical field of mechanical shock absorption, in particular to a support shock absorption device for the hydraulic end of a fracturing pump. Background Art

[0002] The hydraulic end of a fracturing pump pumps fracturing fluid to the formation through high pressure to break rocks and expand fractures, so as to increase the permeability and production of oil and gas wells. Its design needs to take into account the characteristics of high pressure resistance, corrosion resistance and high efficiency conversion to ensure stable operation under harsh working conditions. It is made of high-strength alloy materials and equipped with a precision sealing system, which can effectively reduce leakage and improve the pumping efficiency. In addition, the optimized layout and fluid dynamics design of the hydraulic end further reduce energy consumption and wear, extend the service life of the equipment, and provide a solid technical support for the efficient development of oil and gas fields.

[0003] However, during the continuous high-intensity operation of the hydraulic end of the existing fracturing pump, significant mechanical vibrations will inevitably occur. If these vibrations are not effectively alleviated and controlled for a long time, it will directly cause wear and fatigue damage to the precision components inside the equipment, shortening the overall service life of the equipment. In addition, the vibrations will be transmitted to the surrounding facilities through the base plate and the connection structure, such as the support structure, pipelines and instruments, causing problems such as loosening, fracture or accuracy decline, further increasing the risk of equipment failure. More seriously, the long-term accumulated vibrations may also pose a potential threat to the safety of the operation site, such as causing structural resonance and leading to safety accidents such as equipment tipping over, seriously threatening the safety of personnel and the environment.

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] Embodiment

[0026] For the hydraulic end support shock absorption device of the fracturing pump, please refer to Figures 1-4, including a substrate 1, on which the hydraulic end body 2 of a fracturing pump is assembled at the upper end. A plurality of adjusting mechanisms 6 are arranged in a circular pattern on the outer side of the substrate 1. A plurality of shock-absorbing mechanisms 3 for shock-absorbing the substrate 1 are arranged in a circular pattern on the outer side of the substrate 1. On one side of each of the plurality of shock-absorbing mechanisms 3, a connecting mechanism 4 is provided. On one side of each of the plurality of connecting mechanisms 4, a docking mechanism 5 for respectively docking the plurality of adjusting mechanisms 6 with the plurality of connecting mechanisms 4 is provided. During the operation of the hydraulic end body 2 of the fracturing pump, the generated vibrations are first transmitted to the substrate 1. In order to effectively reduce the influence of these vibrations on the substrate 1 and surrounding structures, a plurality of shock-absorbing mechanisms 3 are arranged in a circular pattern on the outer side of the substrate 1. Through the flexible connection of the shock absorber 305 and the turnbuckle 302 inside each shock-absorbing mechanism 3, the shock-absorbing mechanism 3 can absorb and disperse the vibration energy from the substrate 1. At the same time, the connecting mechanism 4 provided on one side of the shock-absorbing mechanism 3 is connected to the shock absorber 305 by using the upper connecting rod 401, the lower connecting rod 404, the upper ball head 403 and the lower ball head 407 to form a stable and adjustable connection, ensuring the maximization of the shock-absorbing effect. In order to further adapt to different working environments and adjustment requirements, the plurality of adjusting mechanisms 6 are connected to the connecting mechanism 4 through the docking mechanism 5. The docking mechanism 5 docks the ball sleeve 501 with the ball head of the connecting mechanism 4 to achieve a stable connection while allowing the adjusting mechanism 6 to perform necessary fine-tuning. Inside the adjusting mechanism 6, through the precise cooperation of the sliding frame 601 and the sliding rod 603, and the rotational drive of the lead screw 6010, the position of the support cone 608 and the contact pressure with the ground can be precisely adjusted, thereby ensuring the stability and safety of the equipment. Through modular design, the entire system realizes the flexible connection and adjustment between components, effectively improving the stability and reliability of the hydraulic end of the fracturing pump during operation.

[0027] Such as Figure 5As shown, the shock absorption mechanism 3 includes a mounting plate 301, which is fixedly connected to one side of the substrate 1. At the upper parts on both sides of the mounting plate 301, swivel buckles 302 are fixedly connected. At one side of the mounting plate 301 away from the substrate 1, a docking plate 303 is fixedly connected. At the upper and lower ends of the side of the docking plate 303 away from the mounting plate 301, mounting pipes 304 are fixedly connected. The outside of both swivel buckles 302 is rotatably connected with shock absorbers 305. The shock absorption mechanism 3 is mainly composed of a mounting plate 301, swivel buckles 302, a docking plate 303, mounting pipes 304 and shock absorbers 305. When the hydraulic end body 2 of the fracturing pump generates vibrations during operation, these vibrations are first transmitted to the mounting plate 301 through the substrate 1. The shock absorbers 305 on both sides of the mounting plate 301 can flexibly absorb and disperse the vibration energy through the rotational connection of the swivel buckles 302, effectively reducing the direct impact of the vibrations on the substrate 1 and surrounding structures. At the same time, the other end of the shock absorber 305 is connected to the support rod 406 in the connection mechanism 4, further enhancing the shock absorption effect and making the entire system more stable. Through the shock absorbers 305 with double-end connections, the vibration energy can be effectively absorbed and dispersed, significantly reducing the noise and vibrations during equipment operation and protecting the equipment from long-term vibration damage. The design of the swivel buckles 302 enables the shock absorbers 305 to flexibly adjust the angle according to the vibration direction, improving the shock absorption efficiency. The shock absorption mechanism 3, as an independent module, is convenient for installation, maintenance and replacement, reducing the maintenance cost and time.

[0028] As Figures 6-7As shown in the figure, the connecting mechanism 4 includes an upper connecting rod 401 and a lower connecting rod 404. The upper connecting rod 401 is rotatably sleeved inside the upper mounting pipe 304, and the lower connecting rod 404 is rotatably sleeved inside the lower mounting pipe 304. Both sides of the upper connecting rod 401 are fixedly connected with upper fork arms 402. At one end of the upper fork arm 402 away from the upper connecting rod 401, an upper ball head 403 is fixedly connected. Both sides of the lower connecting rod 404 are fixedly connected with lower fork arms 405. On both sides of the lower fork arm 405 away from the lower connecting rod 404, support rods 406 are fixedly connected. At one end of the lower fork arm 405 away from the lower connecting rod 404, a lower ball head 407 is fixedly connected. One end of each of the two shock absorbers 305 is rotatably connected to the far ends of the two support rods 406 away from each other. The connecting mechanism 4 is connected to the docking plate 303 of the shock absorption mechanism 3 through the upper connecting rod 401 and the lower connecting rod 404. At the same time, a stable connection structure is formed by using the upper fork arm 402, the upper ball head 403, the lower fork arm 405, the lower ball head 407 and the support rod 406. This design not only enhances the structural stability, but also enables the connecting mechanism 4 to flexibly adjust its position with the expansion and contraction of the shock absorber 305, ensuring the maximization of the shock absorption effect. Through multi-point connection and ball head design, the connecting mechanism 4 can effectively transmit the shock absorption force while maintaining the structural stability and reliability. The design of the upper ball head 403 and the lower ball head 407 enables the connecting mechanism 4 to flexibly adjust along the movement track of the shock absorber 305, reducing the additional stress generated by vibration. The modular design makes the connecting mechanism 4 easy to install and disassemble, facilitating maintenance and replacement.

[0029] As Figure 5 shown in the figure, the docking mechanism 5 includes two ball sleeves 501. The two ball sleeves 501 are respectively rotatably sleeved outside the upper ball head 403 and the lower ball head 407. The other ends of the two ball sleeves 501 are fixedly connected with a connecting plate 502. The docking mechanism 5 connects the upper ball head 403 and the lower ball head 407 of the connecting mechanism 4 to the connecting plate 502 of the adjusting mechanism 6 through the two ball sleeves 501. This design not only ensures the connection stability, but also enables the adjusting mechanism 6 to adjust its position as needed. The cooperation between the ball sleeve 501 and the ball head makes the connection tighter and more stable, reducing the risk of loosening caused by vibration. The design of the docking mechanism 5 enables the adjusting mechanism 6 to easily achieve fine adjustment in the vertical or horizontal direction to adapt to different working environments and shock absorption requirements. Through the simple design of the ball sleeve 501 and the connecting plate 502, complex connection functions are realized, simplifying the overall structure.

[0030] As Figures 8-9As shown, the adjusting mechanism 6 includes a sliding frame 601. The sliding frame 601 is fixedly connected to one side of the connecting plate 502. A plurality of guide grooves 602 are fixedly connected in a circular arrangement inside the sliding frame 601. A sliding rod 603 is slidably sleeved inside the sliding frame 601. A plurality of guide rails 604 are fixedly connected in a circular arrangement on the outer side of the sliding rod 603. The plurality of guide rails 604 are respectively slidably sleeved inside the plurality of guide grooves 602. A support plate 605 is fixedly connected to the lower end of the sliding rod 603. A threaded sleeve 606 is fixedly connected to the center of the lower end of the support plate 605. A docking rod 607 is threadedly sleeved inside the threaded sleeve 606. The docking rod 607 and the threaded sleeve 606 are detachably connected. A support cone 608 is fixedly connected to the lower end of the docking rod 607. A top cover 609 is fixedly connected to the upper end of the sliding frame 601. A lead screw 6010 is threadedly sleeved inside the sliding rod 603. The outer side of the lead screw 6010 is sleeved with a bearing at the upper part and is sleeved at the center of the inside of the top cover 609. And a handwheel 6011 is fixedly connected to the top end of the lead screw 6010. The adjusting mechanism 6 realizes the up and down sliding of the sliding rod 603 through the cooperation of the guide grooves 602 and the guide rails 604 inside the sliding frame 601. The support plate 605 and the threaded sleeve 606 at the lower end of the sliding rod 603 are used to install the docking rod 607 and the support cone 608. By rotating the handwheel 6011 to drive the lead screw 6010 to rotate, the lifting position of the sliding rod 603 can be accurately controlled, so as to adjust the contact pressure and stability between the support cone 608 and the ground. Through the precise cooperation of the lead screw 6010 and the threaded sleeve 606, the precise adjustment of the position of the support cone 608 is realized, ensuring the stability and safety of the equipment. The design of the adjusting mechanism 6 enables the equipment to easily adapt to the requirements of different terrains and working environments, improving the applicability and flexibility of the equipment. The design of the handwheel 6011 makes the adjustment process more intuitive and convenient, reducing the operation difficulty and complexity.

[0031] Working principle: The shock absorption mechanism 3 is composed of a mounting plate 301, a swivel buckle 302, a docking plate 303, a mounting pipe 304 and a shock absorber 305. When the hydraulic end body 2 of the fracturing pump operates, the vibration generated is transmitted to the mounting plate 301 through the base plate 1. At this time, the shock absorbers 305 on both sides of the mounting plate 301 are flexibly connected through the swivel buckle 302, effectively absorbing and dispersing the vibration energy, reducing the direct impact on the base plate 1 and surrounding structures. The other end of the shock absorber 305 is connected to the support rod 406 of the connecting mechanism 4, further enhancing the shock absorption effect and ensuring the stability of the system. The connecting mechanism 4 forms a stable and flexible connection structure with the shock absorption mechanism 3 through components such as the upper connecting rod 401, the lower connecting rod 404, the upper fork arm 402, the upper ball head 403, the lower fork arm 405, and the lower ball head 407, and can adjust its position with the telescoping of the shock absorber 305 to maximize the shock absorption effect. The docking mechanism 5 tightly connects the ball head of the connecting mechanism 4 with the connecting plate 502 of the adjusting mechanism 6 by using a ball sleeve 501, which is both stable and convenient for the fine adjustment of the adjusting mechanism 6. The adjusting mechanism 6 realizes the precise lifting of the sliding rod 603 by the cooperation of the guide groove 602 in the sliding frame 601 and the guide rail 604, and then adjusts the contact pressure and stability between the support cone 608 and the ground. The handwheel 6011 drives the screw rod 6010 to rotate, which is precisely matched with the threaded sleeve 606 to ensure the precise adjustment of the position of the support cone 608 to adapt to different terrains and working requirements, and improve the stability and flexibility of the equipment.
