Description

Technical Field

[0001] The invention relates to the technical field of shock absorbers, and in particular to an assembled hydraulic shock absorber. Background Art

[0002] In the modern industrial field, especially in situations involving precision electronic equipment, such as electrical cabinets in CNC machine rooms, the operational stability and reliability are crucial. A large number of electronic components are integrated inside the electrical cabinet. These components not only need to withstand normal current and voltage loads during the operation of the equipment, but may also face vibration interference caused by the external environment or the operation of the equipment itself. Vibration may not only cause loose electrical connections and component damage, but also cause signal transmission errors, thereby affecting the performance and safety of the entire system.

[0003] To effectively alleviate this problem, the industry has widely adopted shock absorbers as a key protection method, aiming to isolate or absorb vibration energy from the outside or inside to protect sensitive components in the electrical cabinet from damage. Traditional shock absorber designs mostly rely on materials or structures such as rubber and springs. These materials, due to their good elasticity and recovery ability, can effectively disperse and absorb vibration energy to a certain extent, ensuring the stable operation of the electrical cabinet in a vibrating environment.

[0004] However, existing shock absorption technology faces a significant challenge in practical applications: the trade-off between anti-rollover capability and shock absorption effect. Specifically, when the shock absorber design focuses on enhancing anti-rollover capability, that is, preventing the electrical cabinet from tilting or tipping over under strong vibrations, its shock absorption effect tends to decrease, resulting in insufficient isolation of subtle vibrations; on the contrary, if the shock absorption effect is excessively pursued, although it can effectively isolate subtle vibrations, the anti-rollover stability of the electrical cabinet may be affected when encountering large vibrations, increasing the risk of equipment tipping over.

[0005] Therefore, how to ensure that the electrical cabinet has good anti-overturning stability in a vibration environment and achieve efficient vibration isolation has become a technical problem that needs to be solved urgently. The solution to this problem is not only related to the long-term stable operation of the electrical cabinet and its internal components, but also the key to improving the reliability and safety of the entire CNC machine room and even the entire industrial system.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0022] The purpose of the present invention is to provide an assembled hydraulic shock absorber to solve the problems existing in the prior art. The hydraulic lifting platform and the hydraulic bearing member are connected by both a first bearing plate and a hydraulic pipeline, which can absorb the vibration generated during the working process of the bearing equipment, delay the release of vibration energy, and provide reverse resistance to reduce the impact of vibration on the bearing equipment. At the same time, the unidirectional force when the bearing equipment overturns is decomposed into multiple forces in the same direction, providing a gradually increasing supporting force as the overturning occurs, and at the same time assisting the bearing equipment in resetting to improve the stability of the bearing equipment.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 to Figure 10 As shown, the present invention provides an assembled hydraulic shock absorber, including a hydraulic lifting platform 11, a hydraulic bearing member 9, a first bearing plate 27 and a hydraulic pipeline 10. The components can be assembled according to actual needs, and the number or position of the corresponding components can be adjusted according to the change of the use environment during the later use. The hydraulic lifting platform 11 has a hydraulic chamber 17 with a variable volume. On the one hand, the change of the volume of the hydraulic chamber 17 can adjust the hydraulic oil entering and exiting the hydraulic chamber 17, and on the other hand, the hydraulic oil entering and exiting the hydraulic chamber 17 can change the volume of the hydraulic chamber 17. The hydraulic lifting platform 11 has a relatively movable end and a fixed end. The movable end of the hydraulic lifting platform 11 is used to abut against a bearing device. The bearing device can be an electrical cabinet in a CNC machine room or other equipment in an industrial field that needs to be shock-absorbing. The hydraulic bearing member 9 has a pressure chamber 13 with a variable volume. On the one hand, the change of the volume of the pressure chamber 13 can adjust the hydraulic oil entering and exiting the pressure chamber 13, and on the other hand, the hydraulic oil entering and exiting the pressure chamber 13 can change the volume of the pressure chamber 13. The hydraulic bearings 9 are distributed around the bottom of the hydraulic lifting platform 11, for example, two, four or eight hydraulic bearings 9 can be evenly distributed. The hydraulic bearings 9 have a relatively movable end and a fixed end. The movable end of the hydraulic bearing 9 and the fixed end of the hydraulic lifting platform 11 are respectively connected to the upper and lower sides of the first bearing plate 27. Multiple hydraulic lifting platforms 11 can share the force with multiple hydraulic bearings 9. Each hydraulic lifting platform 11 is connected to at least two hydraulic bearings 9. When connected, the hydraulic chamber 17 of the hydraulic lifting platform 11 is connected to the pressure chamber 13 of the hydraulic bearing 9 through the hydraulic pipeline 10.

[0025] The main function of the hydraulic bearing 9 is to receive the force of the bearing device transmitted by the first bearing plate 27, absorb vibration energy, and delay the release of vibration energy. When the received pressure increases, the pressure is transmitted to the hydraulic lifting platform 11 through the hydraulic pipeline 10, and when the received pressure decreases, the pressure of the hydraulic lifting platform 11 is received through the hydraulic pipeline 10. The hydraulic pipeline 10 is a flexible hollow round tube, and its main function is to connect the hydraulic bearing 9 and the hydraulic lifting platform 11, and transmit liquid pressure under the action of pressure. After one hydraulic pipeline 10 is adapted to one hydraulic bearing 9, it is connected to the hydraulic lifting platform 11. The main function of the hydraulic lifting platform 11 is to reduce the height when the pressure applied by the bearing device increases, receive the pressure and transmit it to the hydraulic bearing 9, and then receive the pressure transmitted by the hydraulic bearing 9 through the hydraulic pipeline 10, and extend the height. When the pressure applied by the bearing device decreases, it receives the pressure transmitted by the hydraulic bearing 9 through the hydraulic pipeline 10, extends the height, and then receives the pressure transmitted to the hydraulic bearing 9 to reduce the height.

[0026] The hydraulic lifting platform 11 and the hydraulic bearing member 9 of the present invention are connected by both the first bearing plate 27 and the hydraulic pipeline 10. The hydraulic bearing member 9 is distributed around the bottom of the hydraulic lifting platform 11, and can absorb the vibration generated during the working process of the bearing equipment, delay the release of vibration energy, and provide reverse resistance to reduce the impact of vibration on the bearing equipment. At the same time, the unidirectional force when the bearing equipment overturns is decomposed into multiple forces in the same direction, providing a gradually increasing supporting force as the overturning occurs, and at the same time assisting the bearing equipment to reset and improve the stability of the bearing equipment.

[0027] In one embodiment, if Fig. 9 As shown, the hydraulic lifting platform 11 includes a hydraulic warehouse 17 and a multi-section lifting member 18 connected to the hydraulic warehouse 17.

The setting method of being divided into multiple sections can have a wider lifting range. The multi-section lifting member 18 is composed of one or more sleeves and a plugging head that are mutually sleeved. A limiting structure can be set between adjacent sleeves or between adjacent sleeves and plugging heads to prevent them from falling out. The plugging head can adopt a columnar structure, and its outer diameter is matched with the inner diameter of the innermost sleeve. The internal space of the hydraulic warehouse 17 is connected to the internal space of the multi-section lifting member 18, and the lifting and lowering of the multi-section lifting member 18 is directly related to the change of its internal space (volume).

[0028] In one embodiment, for the setting of the limiting structure in the multi-section lifting member 18, the plugging head on the inner diameter side is provided with a limiting block on its outer diameter side, the sleeve on the inner diameter side is provided with a limiting block on its outer diameter side, and the sleeve on the outer diameter side is provided with a limiting groove on its inner diameter side. When the adjacent plugging heads and sleeves are matched and when the adjacent sleeves are matched, the limiting blocks are stuck in the limiting grooves, so that the plugging heads and sleeves can be lifted (retracted) within a certain range, thereby ensuring the stability of the structure.

[0029] In one embodiment, if Figure 8 As shown, the hydraulic bearing member 9 includes a pressure chamber 13 and a hydraulic bearing plate 12 connected to the pressure chamber 13. The hydraulic bearing plate 12 includes an inner plate located inside the pressure chamber 13 and an outer plate located outside the pressure chamber 13. The inner plate and the outer plate are connected by a connecting column. The inner plate can be limited by the flange at the end of the pressure chamber 13, so that the hydraulic bearing plate 12 can only move within a certain range to avoid falling out of the pressure chamber 13. The outer ring of the inner plate is provided with a limiting flow ring, which is used to block the passage of liquid and ensure the sealing of the pressure chamber 13.

[0030] In one embodiment, the hydraulic bearing member 9 further includes a buffer spring 16, and the buffer spring 16 mainly functions to buffer the sudden pressure change of the bearing device received by the hydraulic bearing plate 12. One or more buffer springs 16 may be provided. When multiple buffer springs 16 are provided, they are evenly distributed in the pressure chamber 13, and four buffer springs 16 are arranged opposite to each other in the pressure chamber 13. The top of the buffer spring 16 abuts against the inner plate, and the bottom of the buffer spring 16 abuts against the bottom surface of the pressure chamber 13. In order to ensure that the buffer spring 16 is not skewed in the working state, a spring upper limit 14 and a spring lower limit 15 may be respectively provided at both ends of the buffer spring 16. The spring upper limit 14 and the spring lower limit 15 are annular structures, and the ends of the buffer spring 16 may be clamped on the inside to limit the position of the buffer spring 16.

The grading carrying box 4 can be a hollow rectangular box with a rectangular hole on the top, and the first carrying plate 27 is covered under the hole. The hydraulic bearing 9 and the first carrying plate 27 are located inside the grading carrying box 4. The first carrying plate 27 slides up and down inside the grading carrying box 4. The top of the grading carrying box 4 can be provided with an internal limit so that the first carrying plate 27 does not separate from the grading carrying box 4. It can be seen from the above content that the hydraulic bearing 9 always moves within the internal range of the grading carrying box 4, and the movable end of the hydraulic lifting platform 11 can extend out of the grading carrying box 4 to be able to abut against the supporting bearing device.

[0032] In one embodiment, if Figure 7 As shown, it also includes a pressure-bearing component loading cylinder 7, which can be a hollow cylindrical cylinder with a pancake-shaped space at the bottom. The hydraulic bearing member 9 is clamped in the pressure-bearing component loading cylinder 7. The inner diameter side of the pressure-bearing component loading cylinder 7 can be provided with one or more annular convex strips, and the outer diameter side of the hydraulic bearing member 9 can be provided with an annular groove. The annular convex strip and the annular groove cooperate to fix the hydraulic bearing member 9. The pressure-bearing component loading cylinder 7 is used to protect the hydraulic bearing member 9. The movable end of the hydraulic bearing member 9 can extend out of the pressure-bearing component loading cylinder 7 to ensure the normal operation of the hydraulic bearing member 9.

[0033] In one embodiment, a carrier box arrangement opening 8 is provided on the side of the graded carrier box 4, and the carrier box arrangement opening 8 is arranged on the front of the graded carrier box 4, and can be a rectangular hole. The carrier box arrangement opening 8 is used for the hydraulic bearing member 9 and the pressure-bearing member loading cylinder 7 to enter and exit the graded carrier box 4. When the arrangement quantity and position of the hydraulic bearing member 9 and the pressure-bearing member loading cylinder 7 in the graded carrier box 4 are adjusted, they can enter and exit through the carrier box arrangement opening 8.

The hydraulic bearing 9 determines the arrangement level according to the importance of the bearing equipment and the probability of overturning (see Table 1). The levels are divided into level one, level two, and level three. Different arrangements can be made according to different levels to meet different needs.

Place the bearing device on the apparatus, the second bearing plate 19 contacts the bearing device, and the bearing device applies pressure to the second bearing plate 19 under the action of gravity. When the applied pressure is a uniform force, the second bearing plate 19 transmits direct pressure downward to the four hydraulic lifting platforms 11, and the hydraulic lifting platforms 11 contract under the direct pressure, and the hydraulic lifting platforms 11 are lowered. The liquid in the hydraulic lifting platforms 11 is compressed and flows through the hydraulic pipeline 10 to the hydraulic bearing member 9, and at the same time, the tilting telescopic member 20 is vertically compressed as the hydraulic lifting platform 11 is lowered.

[0046] S6. The hydraulic bearing component 9 receives the liquid pressure transmitted by the hydraulic lifting platform 11 through the hydraulic pipeline 10. At the same time, the hydraulic lifting platform 11 transmits direct pressure to the hydraulic bearing component 9 through the first bearing plate 27. The hydraulic bearing component 9 receives the direct pressure transmitted by the hydraulic bearing component 9 through the first bearing plate 27. The direct pressure received by the hydraulic bearing component 9 causes the hydraulic bearing component 9 to contract, and the liquid pressure received by the hydraulic bearing component 9 causes the hydraulic bearing component 9 to extend. During the process, the direct pressure received by the hydraulic bearing component 9 and the liquid pressure received by the hydraulic bearing component 9 offset each other.

[0047] S7. When the direct pressure received by the hydraulic bearing component 9 is greater than the liquid pressure received by the hydraulic bearing component 9, the hydraulic bearing component 9 continues to contract, and the hydraulic lifting platform 11 lowers its height as a whole. The hydraulic lifting platform 11 transmits direct pressure to the hydraulic bearing component 9 through the first bearing plate 27. At the same time, the liquid in the hydraulic bearing component 9 flows to the hydraulic lifting platform 11 through the hydraulic pipeline 10 under the action of pressure. The hydraulic lifting platform 11 receives the liquid pressure transmitted by the hydraulic bearing component 9 through the hydraulic pipeline 10, and the hydraulic lifting platform 11 extends and increases its height to keep the bearing equipment stable. When the direct pressure received by the hydraulic bearing member 9 is less than the liquid pressure received by the hydraulic bearing member 9, the hydraulic bearing member 9 gradually extends, the hydraulic lifting platform 11 is raised in height as a whole, the hydraulic bearing member 9 transmits direct pressure to the hydraulic lifting platform 11 through the first bearing plate 27, and at the same time, the liquid in the hydraulic lifting platform 11 flows toward the hydraulic bearing member 9 through the hydraulic pipeline 10 under the action of pressure, the hydraulic bearing member 9 receives the liquid pressure transmitted by the hydraulic lifting platform 11 through the hydraulic pipeline 10, the hydraulic lifting platform 11 contracts, and the hydraulic lifting platform 11 lowers in height until the bearing equipment is stable, thereby completing the deployment of the bearing equipment on the device.

[0048] S8. When the bearing device starts to operate, the bearing device generates vibration, and the vibration is transmitted downward through the second bearing plate 19. The hydraulic lifting platform 11 receives the direct pressure transmitted by the second bearing plate 19. When the vibration increases, the height of the hydraulic lifting platform 11 decreases and transmits direct pressure to the hydraulic bearing member 9 through the first bearing plate 27. At the same time, the hydraulic lifting platform 11 transmits liquid pressure to the hydraulic bearing member 9 through the hydraulic pipeline 10, as described in step S7, the relationship between the direct pressure received by the hydraulic bearing member 9 and the liquid pressure received by the hydraulic bearing member 9 and the device action mode, and the continuous action occurs with the vibration generated by the bearing device; when the vibration decreases, the hydraulic lifting platform 11 increases in height and receives the direct pressure transmitted by the hydraulic bearing member 9 through the first bearing plate 27. At the same time, the hydraulic lifting platform 11 receives the liquid pressure transmitted by the hydraulic bearing member 9 through the hydraulic pipeline 10, as described in step S7, the relationship between the direct pressure received by the hydraulic bearing member 9 and the liquid pressure received by the hydraulic bearing member 9 and the device action mode, and the continuous action occurs with the vibration generated by the bearing device, thereby completing the vibration weakening effect and keeping the bearing device stable.

[0049] S9. When the bearing device tends to overturn, the second bearing plate 19 is subjected to the pressure increase in a single direction, and at the same time, the pressure decrease in the opposite direction. When the second bearing plate 19 begins to tilt, the tilting telescopic member 20 tilts along with the second bearing plate 19. When the degree of tilt gradually increases, the tilting telescopic member 20 limits the second bearing plate 19 from continuing to tilt, so that the second bearing plate 19 applies pressure to the hydraulic lifting platform 11 in the direction of increasing pressure.

[0050] S10. One or more hydraulic lifts 11 in the direction of increasing pressure receive the increased pressure transmitted by the second bearing plate 19, the height of the hydraulic lift 11 is reduced and direct pressure is transmitted to the hydraulic bearing member 9 through the first bearing plate 27, and the hydraulic lift 11 transmits liquid pressure to the hydraulic bearing member 9 through the hydraulic pipeline 10. At the same time, one or more hydraulic lifts 11 in the direction of decreasing pressure receive the reduced pressure transmitted by the second bearing plate 19, the height of the hydraulic lift 11 is increased and direct pressure is transmitted to the hydraulic bearing member 9 through the first bearing plate 27, and the hydraulic lift 11 receives liquid pressure transmitted to the hydraulic bearing member 9 through the hydraulic pipeline 10.

[0051] S11. In the direction of pressure increase, the hydraulic bearing component 9 receives the direct pressure transmitted by the hydraulic lifting platform 11 through the first bearing plate 27, and the hydraulic bearing component 9 receives the liquid pressure transmitted by the hydraulic lifting platform 11 through the hydraulic pipeline 10. The direct pressure and the liquid pressure are offset in the hydraulic bearing component 9. As the direct pressure is continuously applied in the hydraulic bearing component 9, the liquid pressure continues to increase until the direct pressure transmitted by the hydraulic lifting platform 11 received by the hydraulic bearing component 9 through the first bearing plate 27 gradually decreases, thereby completing the anti-overturning action of the loading equipment of the device.

[0052] S12. In the direction of pressure reduction, the hydraulic lifting platform 11 is extended as a whole through the hydraulic bearing member 9, and the hydraulic lifting platform 11 extends itself through the pressure transmission of the hydraulic pipeline 10. The hydraulic lifting platform 11 contacts the second bearing plate 19 through overall lifting and extension.

[0053] S13. In the direction of increasing pressure, the pressure transmitted by the load-bearing device to the second load-bearing plate 19 gradually decreases. When the pressure transmitted by the load-bearing device to the second load-bearing plate 19 and the pressure transmitted by the hydraulic lifting platform 11 to the second load-bearing plate 19 become close, the load-bearing device will fall back in the direction of decreasing pressure and thus turn into the direction of increasing pressure. The device action is as described in step S11, and the original direction of increasing pressure is turned into the direction of decreasing pressure. The device action is as described in step S12. As the device continues to operate, the load-bearing device gradually becomes stable. At this point, the device completes the anti-overturning action of the load-bearing device.
