Its core function is to achieve gas pressurization and transportation. It is widely used in industrial production, energy supply, aerospace and other fields. It can not only provide high-pressure gas sources for chemical reactions and assist in natural gas liquefaction and transportation, but also provide power for pneumatic tools, ensure a stable supply of gas in scenarios such as diving breathing and medical oxygen supply, and at the same time increase the gas energy density through the compression process to meet the specific needs of different industries for gas pressure and flow.

[0003] However, existing gas compression machinery will produce significant vibrations during actual operation.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a bottom shock-absorbing and buffering device for gas compression machinery.

[0021] Example 1, as Figure 1-8 As shown, a bottom shock absorbing and buffering device for a gas compression machine comprises: A gas compression device 3, the bottom of which is fixedly connected to a mounting frame 2, and a mounting plate 1 is placed on the ground; The damping mechanism 4 is provided with several damping mechanisms 4, and the damping mechanism 4 includes a support damping spring 6 fixedly connected to the top of the mounting plate 1, and the top of the support damping spring 6 is fixedly connected to the bottom of the mounting frame 2; The damping mechanism 4 also includes a universal block 7 fixedly connected to opposite sides of the mounting plate 1 and the mounting frame 2, respectively. A universal ball joint 8 is rotatably connected inside the universal block 7. A mounting piece 51 is fixedly connected to the top of the universal ball joint 8. A lower sleeve 12 is fixedly connected to the top of the mounting piece 51. An upper sleeve 13 is fixedly connected to the top of the lower sleeve 12. An adjusting rod 14 is airtightly slidably connected inside the upper sleeve 13. The top of the adjusting rod 14 is fixedly connected to the bottom of the universal ball joint 8 at the bottom of the mounting plate 1. The interior of the upper sleeve 13 is filled with hydraulic oil. By setting up the above structure, the two universal ball heads 8 rotate inside the corresponding universal blocks 7, so that when the gas compression equipment 3 is working and generates vibration, the adjustment rod 14 slides inside the upper sleeve 13 and pressurizes or depressurizes the hydraulic oil inside the upper sleeve 13.

[0022] An isolation plate 19 is fixedly connected to the interior of the upper sleeve 13, and a power conversion housing 20 is fixedly connected to the bottom of the isolation plate 19. A first hydraulic gear 21 and a second hydraulic gear 22 are rotatably connected to the interior of the power conversion housing 20. A liquid inlet pipe 34, a liquid outlet pipe 38, and a liquid return pipe 35 are respectively connected to the two sides of the power conversion housing 20. The outside of the liquid return pipe 35 is connected to a liquid storage bag 36. One end of the liquid inlet pipe 34 is connected to the liquid inlet housing 33, which is fixedly connected to the top of the upper sleeve 13. The interior of the liquid inlet housing 33 is slidably connected to a liquid inlet block 39. The bottom of the liquid inlet block 39 is fixedly connected to a liquid inlet spring 40. The bottom of the liquid inlet spring 40 is fixedly connected to the bottom of the inner wall of the liquid inlet housing 33. By setting up the above-mentioned structure, the pressure oil can be driven to move and the first hydraulic gear 21 can be driven to rotate when the hydraulic oil is pressurized. Specifically, when the gas compression equipment 3 vibrates and causes the hydraulic oil pressure inside the upper sleeve 13 to increase, part of the hydraulic oil is pressed into the liquid block 39 to slide inside the liquid inlet shell 33, and the liquid inlet spring 40 is compressed. At this time, the hydraulic oil inside the upper sleeve 13 enters the power conversion shell 20 through the liquid inlet pipe 34 and enters the liquid storage bag 36 through the return liquid pipe 35. The liquid storage bag 36 expands. In the process of the hydraulic oil entering the liquid storage bag 36 through the liquid inlet pipe 34, the first hydraulic gear 21 can be driven to rotate.

[0023] One end of the liquid outlet pipe 38 is connected to the liquid outlet housing 37, which is fixedly connected to the top of the upper sleeve 13. The interior of the liquid outlet housing 37 is slidably connected to a liquid outlet block 41. The bottom of the liquid outlet block 41 is fixedly connected to a liquid outlet tension spring 42. The bottom of the liquid outlet tension spring 42 is fixedly connected to the bottom of the inner wall of the liquid outlet housing 37. By setting the above-mentioned structure, the pressurized oil inside the liquid reservoir 36 can be driven to move and drive the second hydraulic gear 22 to rotate when the hydraulic oil is decompressed. Specifically, when the gas compression device 3 vibrates and causes the hydraulic oil pressure inside the upper sleeve 13 to be in a negative pressure state, at this time, the liquid outlet block 41 moves inside the liquid outlet shell 37 and drives the liquid outlet tension spring 42 to stretch, so that the liquid outlet pipe 38 is connected to the interior of the upper sleeve 13, the liquid reservoir 36 contracts, and the hydraulic oil inside the liquid reservoir 36 flows back to the interior of the upper sleeve 13 through the liquid outlet pipe 38. In the process of the hydraulic oil inside the liquid reservoir 36 flowing back to the interior of the upper sleeve 13 through the liquid outlet pipe 38, the second hydraulic gear 22 can be driven to rotate; It is worth mentioning that the first hydraulic gear 21 and the second hydraulic gear 22 rotate in the same direction.

[0024] The bottoms of the first hydraulic gear 21 and the second hydraulic gear 22 are both fixedly connected to a transmission rod 23, the bottom of the transmission rod 23 is slidably connected to a transmission block 25, the top of the transmission block 25 is fixedly connected to an inclined block 27, the top of the inclined block 27 is fixedly connected to an engaging block 28, and an engaging groove 26 is provided at the bottom of the transmission rod 23. One side of the engaging block 28 abuts against one side of the engaging groove 26, and one side of the engaging block 28 is slidably connected to one side of the engaging groove 26. The top of the lower sleeve 12 is fixedly connected to two telescopic sleeves 31, and the tops of the two telescopic sleeves 31 are both fixedly connected to damping plates 52. The tops of the two damping plates 52 are both fixedly connected to the bottoms of the adjacent transmission blocks 25, and the interiors of the two telescopic sleeves 31 are both fixedly connected to transmission springs 32; The top of the lower sleeve 12 is rotatably connected to two transmission gears 24, and the two transmission blocks 25 are slidably connected to the inside of the adjacent transmission gears 24. The tops of the two transmission gears 24 are provided with slide grooves 29, and the outsides of the two transmission blocks 25 are fixedly connected with sliders 30. The sliders 30 on the outsides of the two transmission blocks 25 are adapted to the slide grooves 29 on the tops of the adjacent transmission gears 24.

[0025] By setting the above-mentioned structure, the rotation of the first hydraulic gear 21 or the second hydraulic gear 22 can drive the adjacent transmission gear 24 to rotate. Specifically, when the first hydraulic gear 21 or the second hydraulic gear 22 rotates, it drives the transmission rod 23 thereon to rotate. The rotation of the transmission rod 23 presses one side of the transmission block 25. Since the transmission block 25 slides on the top of the telescopic sleeve 31 through the damping plate 52, at this time, one side of the meshing groove 26 slides on one side of the inclined block 27, and the transmission spring 32 is compressed to drive the telescopic sleeve 31 to contract, and drives the transmission block 25 to move downward. In the process of the transmission block 25 moving downward, the slider 30 thereon cooperates with the slide groove 29, and one side of the meshing groove 26 abuts against one side of the meshing block 28. At this time, the transmission rod 23 continues to rotate to drive the transmission block 25 to rotate, and the rotation of the transmission block 25 can drive the transmission gear 24 to rotate through the cooperation between the slider 30 and the slide groove 29.

[0026] The top of the mounting plate 51 is rotatably connected to a rifle sleeve 9, the internal threads of the rifle sleeve 9 are screwed to a rifle rod 16, the rifle rod 16 is slidably connected to the outside of the upper sleeve 13, the top of the rifle rod 16 is rotatably connected to a connecting ring 10, the top of the connecting ring 10 is fixedly connected to an adjusting spring 11, and the top of the adjusting spring 11 is fixedly connected to the bottom of the universal block 7 at the bottom of the mounting frame 2; The top of the lower sleeve 12 is rotatably connected to a gear ring 15 , which is engaged with two transmission gears 24 , and the outside of the gear ring 15 is fixedly connected to the inner wall of the rifle sleeve 9 .

[0027] By setting the above structure, the height of the adjustment spring 11 can be adjusted, and the shock absorption performance of the shock absorption mechanism 4 can be indirectly adjusted. Specifically, one of the two transmission gears 24 rotates to drive the ring gear 15 to rotate, and the rotation of the ring gear 15 drives the rifle sleeve 9 to rotate on the top of the mounting plate 51. The rotation of the rifle sleeve 9 drives the rifle rod 16 to move upward, and the movement of the rifle rod 16 drives the positioning block 18 to move, thereby controlling the height of the adjustment spring 11 and indirectly controlling the shock absorption performance of the adjustment spring 11. More specifically, in the working vibration scenario of the gas compression equipment 3, the height of the compression adjustment spring 11, that is, adjusting the pre-compression amount, can control the shock absorption performance of the shock absorption mechanism 4 to a certain extent. By changing the height of the adjustment spring 11, the initial stress state of the adjustment spring 11 can be adjusted. When the compression amount increases, the stiffness of the adjustment spring 11 is relatively improved, which can suppress high-frequency vibrations more quickly and reduce the mechanical resonance amplitude; when the compression amount is small, more deformation space is retained, and the buffering of low-frequency and large-amplitude vibrations is softer. The advantage is that there is no need to replace the shock absorption equipment. The vibration characteristics of the machine under different working conditions can be quickly adapted through simple height adjustment, and the vibration suppression effect and equipment operation stability can be flexibly balanced, reducing component wear and noise caused by vibration, while reducing the cost and downtime of frequent replacement of shock absorption equipment.

[0028] A positioning groove 17 is provided on the outside of the upper sleeve 13, and a positioning block 18 is fixedly connected to the top of the rifle rod 16. The positioning block 18 is slidably connected to the inside of the positioning groove 17 to limit the rifle rod 16 and prevent the rifle sleeve 9 from driving the rifle rod 16 to rotate when rotating, causing the rifle rod 16 to be unable to retract.

[0029] Example 2, based on Example 1, Figure 9 As shown, a protective mechanism 5 is provided inside the adjusting rod 14. The protective mechanism 5 includes a protective groove 43 opened inside the adjusting rod 14. A protective shell 44 is fixedly connected to the inner wall of the protective groove 43. A first one-way protective head 46 is slidably connected to the bottom of the protective shell 44. A protective tension spring 45 is fixedly connected to the top of the first one-way protective head 46. The top of the protective tension spring 45 is fixedly connected to the inside of the protective shell 44. The first one-way protective head 46 is internally slidably connected to the second one-way protective head 48, the top of the second one-way protective head 48 is fixedly connected to the protective spring 47, the top of the protective spring 47 is fixedly connected to the inside of the first one-way protective head 46, the top of the protective shell 44 is connected to the telescopic bag 49, the top of the telescopic bag 49 is fixedly connected to the sealing piece 50, and the sealing piece 50 is airtightly slidably connected to the inside of the protective groove 43.

[0030] By setting up the above-mentioned structure, it is possible to avoid leakage of hydraulic oil caused by excessive pressure inside the upper sleeve 13. Specifically, when the vibration force generated by the gas compression device 3 cannot drive the adjustment spring 11 to compress, the pressure inside the upper sleeve 13 increases due to the vibration of the gas compression device 3. At this time, the protective spring 47 is compressed, and the second one-way protective head 48 slides inside the first one-way protective head 46. Part of the hydraulic oil enters the telescopic bag 49 through the first one-way protective head 46. The expansion of the telescopic bag 49 drives the sealing piece 50 to slide inside the protective groove 43. The gas on the top of the sealing piece 50 is compressed. When the pressure inside the upper sleeve 13 is weakened due to the vibration of the gas compression device 3, the second one-way protective head 48 returns to its position, the protective tension spring 45 is stretched, and the first one-way protective head 46 slides inside the protective shell 44. The gas on the top of the sealing piece 50 expands, the telescopic bag 49 contracts, and the hydraulic oil inside the telescopic bag 49 flows back to the interior of the upper sleeve 13 to facilitate the next operation of the shock absorbing mechanism 4.

[0031] The working principle of the present invention is as follows: when the gas compression device 3 generates vibration during operation, the regulating rod 14 slides inside the upper sleeve 13 and pressurizes or depressurizes the hydraulic oil inside the upper sleeve 13; When the gas compression device 3 vibrates, causing the hydraulic oil pressure inside the upper sleeve 13 to increase, part of the hydraulic oil forces the liquid inlet block 39 to slide inside the liquid inlet shell 33, and the liquid inlet spring 40 is compressed. At this time, the hydraulic oil inside the upper sleeve 13 enters the power conversion shell 20 through the liquid inlet pipe 34 and enters the liquid reservoir 36 through the liquid return pipe 35. The liquid reservoir 36 expands, and in the process of the hydraulic oil entering the liquid reservoir 36 through the liquid inlet pipe 34, it can drive the first hydraulic gear 21 to rotate; When the gas compression device 3 vibrates, causing the hydraulic oil pressure inside the upper sleeve 13 to be in a negative pressure state, the liquid outlet block 41 moves inside the liquid outlet housing 37, and drives the liquid outlet tension spring 42 to stretch, so that the liquid outlet pipe 38 is connected to the interior of the upper sleeve 13, the liquid reservoir 36 contracts, and the hydraulic oil inside the liquid reservoir 36 flows back to the interior of the upper sleeve 13 through the liquid outlet pipe 38. In the process of the hydraulic oil inside the liquid reservoir 36 flowing back to the interior of the upper sleeve 13 through the liquid outlet pipe 38, the second hydraulic gear 22 can be driven to rotate; When the first hydraulic gear 21 or the second hydraulic gear 22 rotates, the transmission rod 23 thereon is driven to rotate, and the rotation of the transmission rod 23 presses one side of the transmission block 25. Since the transmission block 25 slides on the top of the telescopic sleeve 31 through the damping plate 52, one side of the meshing groove 26 slides on one side of the inclined block 27 at this time, and the transmission spring 32 is compressed to drive the telescopic sleeve 31 to contract, and drives the transmission block 25 to move downward. In the process of the transmission block 25 moving downward, the slider 30 thereon cooperates with the slide groove 29, and one side of the meshing groove 26 abuts against one side of the meshing block 28. At this time, the transmission rod 23 continues to rotate to drive the transmission block 25 to rotate, and the rotation of the transmission block 25 can drive the transmission gear 24 to rotate through the cooperation between the slider 30 and the slide groove 29; When one of the two transmission gears 24 rotates, it drives the ring gear 15 to rotate. The rotation of the ring gear 15 drives the rifle sleeve 9 to rotate on the top of the mounting plate 51. The rotation of the rifle sleeve 9 drives the rifle rod 16 to move upward. The movement of the rifle rod 16 drives the positioning block 18 to move, thereby controlling the height of the adjustment spring 11 and indirectly controlling the shock absorbing performance of the adjustment spring 11. When the vibration force generated by the gas compression device 3 cannot drive the adjustment spring 11 to compress, the pressure inside the upper sleeve 13 increases due to the vibration of the gas compression device 3. At this time, the protective spring 47 is compressed, and the second one-way protective head 48 slides inside the first one-way protective head 46. Part of the hydraulic oil enters the telescopic bag 49 through the first one-way protective head 46. The expansion of the telescopic bag 49 drives the sealing piece 50 to slide inside the protective groove 43. The gas on the top of the sealing piece 50 is compressed. When the pressure inside the upper sleeve 13 is weakened due to the vibration of the gas compression device 3, the second one-way protective head 48 returns to its position, the protective tension spring 45 stretches, the first one-way protective head 46 slides inside the protective shell 44, the gas on the top of the sealing piece 50 expands, the telescopic bag 49 contracts, and the hydraulic oil inside the telescopic bag 49 flows back to the interior of the upper sleeve 13 to facilitate the next operation of the shock absorbing mechanism 4.
