Description

Technical Field

[0001] This utility model relates to the technical field of natural gas compressor accessories, specifically a natural gas compressor mounting base. Background Technology

[0002] Natural gas compressors are the core equipment in the natural gas transportation and storage process. Natural gas compressors are fixed to the ground by mounting brackets.

[0003] However, existing natural gas compressor mounting bases have poor vibration damping performance. Compressor vibrations are easily transmitted to the foundation through the mounting base, causing equipment resonance, base loosening, and even pipeline joint cracking and leakage. Therefore, damping springs are installed on the mounting base, which are fixed by screws and nuts. Due to the vibration of the natural gas compressor, the mounting base vibrates, causing the screws and nuts to loosen, resulting in the damping springs becoming loose and failing to provide adequate vibration damping for the natural gas compressor. To address these issues, an innovative design based on the existing natural gas compressor mounting base is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a natural gas compressor mounting base to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a natural gas compressor mounting base, including a fixed mounting base, a support block installed at the bottom of the fixed mounting base, a movable mounting base provided at the top of the fixed mounting base via a damper, a lead screw fixed at the bottom of the movable mounting base, the lower end of the lead screw passing through the fixed mounting base, a nut threaded onto the lower end of the lead screw, and a first spring nested on the outside of the lead screw, the first spring being located between the fixed mounting base and the movable mounting base; The bottom of the fixed mounting base is provided with a limiting mechanism to prevent the lead screw and nut from loosening.

[0006] Preferably, the limiting mechanism includes a rotating rod, the bottom of the fixed mounting base is fixed with the rotating rod, one end of the rotating rod is rotated with a rotating plate, one end of the movable rod is installed inside the rotating plate, the inner top of the rotating plate is provided with a groove, the top of the movable rod is fixed with a slider, the slider is installed in the groove, a second spring is provided between one side of the slider and the end of the groove, the outer wall of the nut is provided with an annular groove, and the other end of the movable rod is nested inside the annular groove.

[0007] Preferably, the other end of the movable rod is designed with a "J" shape, and the inner side of the other end of the movable rod is in contact with the inner side of the annular groove.

[0008] Preferably, a push block is fixed to the outer wall of the movable rod, and the push block is located between the nut and the rotating plate.

[0009] Preferably, the top of the rotating plate is in contact with the bottom of the fixed mounting base, the rotating rod is designed with a "T" shaped structure, and the bottom upper surface of the rotating rod is in contact with the bottom of the rotating plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: under the elastic force of the second spring, the inner side of the "J"-shaped end of the movable rod can be tightly engaged with the inner side of the annular groove on the nut, thereby preventing loosening between the screw and the nut, avoiding loosening of the screw and the first spring, and facilitating the shock absorption of the movable mounting base and the natural gas compressor fixed on the top of the movable mounting base by the first spring. Pushing the push block causes the movable rod to move away from the nut. The movable rod then moves the slider, which further compresses the second spring. Pulling the push block then causes the movable rod and rotating plate to rotate around the rotating rod, thus moving the movable rod away from the nut and preventing it from obstructing the nut's rotation.

[0013] 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.

[0014] Please see Figure 1-5This utility model provides a technical solution: a natural gas compressor mounting base, including a fixed mounting base 1, a support block 4 fixed at the bottom of the fixed mounting base 1, a movable mounting base 3 fixed at the top of the fixed mounting base 1 by a damper 2, a lead screw 5 fixed at the bottom of the movable mounting base 3, the lower end of the lead screw 5 movably penetrating the interior of the fixed mounting base 1, a nut 7 threadedly connected to the outer side of the lower end of the lead screw 5, and a first spring 6 movably nested on the outer side of the lead screw 5, the first spring 6 being located between the fixed mounting base 1 and the movable mounting base 3; The bottom of the fixed mounting base 1 is provided with a limiting mechanism to prevent the lead screw 5 and nut 7 from loosening.

[0015] The limiting mechanism includes a rotating rod 9. The rotating rod 9 is fixed to the bottom of the fixed mounting base 1. One end of a rotating plate 10 is rotatably mounted on the outside of the rotating rod 9. One end of a movable rod 11 is movably mounted inside the rotating plate 10. A groove 12 is provided on the inner top of the rotating plate 10. A slider 13 is fixed to the top end of the movable rod 11. The slider 13 is movably mounted inside the groove 12. A second spring 14 is provided between one side of the slider 13 and the end of the groove 12. An annular groove 8 is provided on the outer wall of the nut 7. The other end of the movable rod 11 is nested inside the annular groove 8. Under the elastic force of the second spring 14, the movable rod 11 and the annular groove 8 can be tightly engaged together, ensuring that the nut 7 will not move on the screw 5, preventing the screw 5 and the nut 7 from loosening, avoiding the loosening of the first spring 6, and allowing the first spring 6 to properly dampen the vibration of the movable mounting base 3 and the gas compressor fixed on the top of the movable mounting base 3.

[0016] The other end of the movable rod 11 is designed with a "J" shape, and the inner side of the other end of the movable rod 11 fits into the inner side of the annular groove 8, so that the other end of the movable rod 11 can be engaged inside the annular groove 8.

[0017] A push block 15 is fixed to the outer wall of the movable rod 11. The push block 15 is located between the nut 7 and the rotating plate 10. The push block 15 facilitates the movement of the movable rod 11, so that the other end of the movable rod 11 can be separated from the annular groove 8.

[0018] The top of the rotating plate 10 fits into the bottom of the fixed mounting base 1. The rotating rod 9 is designed with a "T" shape. The bottom upper surface of the rotating rod 9 fits into the bottom of the rotating plate 10, so that the rotating plate 10 can rotate around the rotating rod 9 and ensure that the rotating plate 10 will not separate from the rotating rod 9.

[0019] Working principle: such as Figure 4As shown, the second spring 14 is in a compressed state, which allows the second spring 14 to generate a thrust on the slider 13, thereby the slider 13 can generate a thrust on the movable rod 11, so that the inner side of the "J"-shaped end of the movable rod 11 is tightly engaged with the inner side of the annular groove 8 on the nut 7, thereby preventing loosening between the lead screw 5 and the nut 7, avoiding loosening between the lead screw 5 and the first spring 6, which is beneficial for the first spring 6 to dampen the vibration of the movable mounting base 3 and the natural gas compressor fixed on the top of the movable mounting base 3, and the damper 2 between the fixed mounting base 1 and the movable mounting base 3, preventing the vibration frequency of the first spring 6 from being too fast, and improving the vibration damping effect of the natural gas compressor; When it is necessary to remove nut 7, push push block 15. Push block 15 drives movable rod 11 away from nut 7. Movable rod 11 drives slider 13 to move. Slider 13 further compresses the second spring 14. Then pull push block 15. Push block 15 drives movable rod 11 and rotating plate 10 to rotate around rotating rod 9, so that movable rod 11 is away from nut 7, so as to avoid movable rod 11 from hindering the rotation of nut 7. Finally, use a wrench to remove nut 7 from screw 5.
