Description

Technical Field

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

[0002] In the modern industrial field, especially in the case of precision electronic equipment, such as the electrical cabinets in a CNC machine room, the operation stability and reliability are of crucial importance. A large number of electronic components are integrated inside the electrical cabinet. During the operation of the equipment, these components not only need to bear the normal current and voltage loads, but may also face vibration interference caused by the external environment or the operation of the equipment itself. Vibration may not only lead to 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 means, aiming to isolate or absorb the vibration energy from the external or internal environment to protect the sensitive components inside the electrical cabinet from damage. Traditional shock absorber designs mostly rely on materials or structures such as rubber and springs. Due to their good elasticity and recovery ability, these materials 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, the existing shock absorption technologies face a significant challenge in practical applications: the trade-off between the anti-overturning ability and the shock absorption effect. Specifically, when the shock absorber design focuses on enhancing the anti-overturning ability, that is, preventing the electrical cabinet from tilting or overturning under strong vibrations, its shock absorption effect often decreases, resulting in insufficient isolation ability for subtle vibrations. On the contrary, if excessive pursuit of the shock absorption effect, although it can effectively isolate subtle vibrations, when encountering large vibrations, the anti-overturning stability of the electrical cabinet may be affected, increasing the risk of equipment overturning.

[0005] Therefore, how to ensure that the electrical cabinet has good anti-overturning stability in a vibrating environment and achieve efficient vibration isolation has become an urgent technical problem to be solved. 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.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] The object of the present invention is to provide an assembled hydraulic shock absorber to solve the problems existing in the prior art. There are both a first bearing plate connection and a hydraulic pipeline connection between the hydraulic lifting platform and the hydraulic bearing member, which can absorb the vibration generated during the operation 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 single-direction 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 to improve the stability of the bearing equipment.

[0036] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] As Figures 1 to 10 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. Each component can be assembled according to actual needs, and the quantity or position of the corresponding components can be adjusted according to the change of the use environment during the later use process. The hydraulic lifting platform 11 has a hydraulic chamber 17 with a variable volume. On the one hand, the change in the volume of the hydraulic chamber 17 can adjust the inflow and outflow of hydraulic oil into and out of the hydraulic chamber 17. On the other hand, the inflow and outflow of hydraulic oil into and out of the hydraulic chamber 17 can change the volume of the hydraulic chamber 17. The hydraulic lifting platform 11 has a movable end and a fixed end that move relative to each other. The movable end of the hydraulic lifting platform 11 is used to abut against the bearing equipment, and the bearing equipment can be an electrical cabinet in a computer room or other equipment that needs shock absorption in other industrial fields. The hydraulic bearing member 9 has a pressure-bearing chamber 13 with a variable volume. On the one hand, the change in the volume of the pressure-bearing chamber 13 can adjust the inflow and outflow of hydraulic oil into and out of the pressure-bearing chamber 13. On the other hand, the inflow and outflow of hydraulic oil into and out of the pressure-bearing chamber 13 can change the volume of the pressure-bearing chamber 13. The hydraulic bearing members 9 are distributed around the bottom of the hydraulic lifting platform 11. For example, two, four, or eight can be evenly distributed, etc. The hydraulic bearing member 9 has a movable end and a fixed end that move relative to each other. The movable end of the hydraulic bearing member 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 bearing members 9. Each hydraulic lifting platform 11 is connected to at least two hydraulic bearing members 9. When connecting, the hydraulic chamber 17 of the hydraulic lifting platform 11 is communicated with the pressure-bearing chamber 13 of the hydraulic bearing member 9 through the hydraulic pipeline 10.

[0038] The main function of the hydraulic load-bearing member 9 is to receive the acting force of the load-bearing device transmitted by the first load-bearing plate 27, absorb the vibration energy, and delay the release of the vibration energy. When the received pressure increases, the pressure is conducted to the hydraulic lifting platform 11 through the hydraulic pipeline 10. When the received pressure decreases, the hydraulic lifting platform 11's pressure is received through the hydraulic pipeline 10. The hydraulic pipeline 10 is a flexible hollow circular pipe, and its main function is to connect the hydraulic load-bearing member 9 and the hydraulic lifting platform 11, and conduct the liquid pressure under the action of pressure. After a hydraulic pipeline 10 is adapted to a hydraulic load-bearing member 9, it is connected to the hydraulic lifting platform 11. The main function of the hydraulic lifting platform 11 is that when the pressure applied by the loading device increases, it lowers its height, receives the pressure and transmits it to the hydraulic load-bearing member 9, and then receives the pressure transmitted by the hydraulic load-bearing member 9 through the hydraulic pipeline 10 and extends its height. When the pressure applied by the loading device decreases, it receives the pressure transmitted by the hydraulic load-bearing member 9 through the hydraulic pipeline 10 and extends its height, and then receives the pressure transmission to the hydraulic load-bearing member 9 and lowers its height.

[0039] In the hydraulic lifting platform 11 and the hydraulic load-bearing member 9 of the present invention, there are both connections of the first load-bearing plate 27 and connections of the hydraulic pipeline 10. The hydraulic load-bearing members 9 are distributed around the bottom of the hydraulic lifting platform 11, which can absorb the vibration generated during the operation of the load-bearing device, delay the release of the vibration energy, and provide reverse resistance to reduce the impact of the vibration on the load-bearing device. At the same time, the single-direction acting force when the load-bearing device overturns is decomposed into multiple acting forces in the same direction, and a gradually increasing supporting force is provided as the overturning occurs, and at the same time, it assists the load-bearing device to reset to improve the stability of the load-bearing device.

[0040] In one embodiment, as Figure 9 shown, the hydraulic lifting platform 11 includes a hydraulic chamber 17 and multiple lifting members 18 connecting the hydraulic chamber 17. The multiple lifting members 18 can adopt a multi-section sleeve structure. The sleeve can be a ring with a certain height, and the multi-section setting method can have a wider lifting range. The multiple lifting members 18 are composed of one or more sleeves sleeved with each other and plugging heads. A limiting structure can be provided between adjacent sleeves or between adjacent sleeves and plugging heads to prevent them from coming out. The plugging head can adopt a columnar structure, and its outer diameter size is matched with the inner diameter of the innermost sleeve. The internal space of the hydraulic chamber 17 is connected to the internal space of the multiple lifting members 18, and the lifting of the multiple lifting members 18 is directly related to the change of its internal space (volume).

[0041] In one embodiment, for the setting of the limiting structure in the multi-section lifting member 18, the plug 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 adjacent plugs and sleeves are matched and adjacent sleeves are matched, the limiting block is clamped in the limiting groove to realize the lifting (telescoping) of the plug and the sleeve within a certain range, ensuring the stability of the structure.

[0042] In one embodiment, as Figure 8 shown, the hydraulic load-bearing member 9 includes a pressure-bearing chamber 13 and a hydraulic load-bearing plate 12 connected to the pressure-bearing chamber 13. The hydraulic load-bearing plate 12 includes an inner plate located inside the pressure-bearing chamber 13 and an outer plate located outside the pressure-bearing chamber 13. The inner plate and the outer plate are connected by connecting columns. The inner plate can be limited by the flange at the end of the pressure-bearing chamber 13, so that the hydraulic load-bearing plate 12 can only move within a certain range to avoid disengaging from the pressure-bearing chamber 13. A current-limiting ring is provided on the outer circle of the inner plate, and the current-limiting ring is used to block the passage of liquid to ensure the sealing performance of the pressure-bearing chamber 13.

[0043] In one embodiment, the hydraulic load-bearing member 9 further includes a buffer spring 16. The main function of the buffer spring 16 is to buffer the sudden change of the pressure of the load-bearing device received by the hydraulic load-bearing plate 12. One or more buffer springs 16 can be provided. When multiple buffer springs 16 are provided, they are evenly distributed in the pressure-bearing chamber 13. Four buffer springs 16 are arranged oppositely in the pressure-bearing 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-bearing chamber 13. To ensure that the buffer spring 16 is not skewed during the working state, a spring upper limit 14 and a spring lower limit 15 can 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 can be clamped inside to limit the position of the buffer spring 16.

[0044] In one embodiment, as Figure 6 shown, it further includes a hierarchical load-bearing box 4. The hierarchical load-bearing box 4 can be a hollow rectangular box with a rectangular hole at the top, and a first load-bearing plate 27 is covered under the hole. The hydraulic load-bearing member 9 and the first load-bearing plate 27 are located inside the hierarchical load-bearing box 4. The first load-bearing plate 27 slides up and down inside the hierarchical load-bearing box 4. An internal limit can be provided at the top of the hierarchical load-bearing box 4 to prevent the first load-bearing plate 27 from disengaging from the hierarchical load-bearing box 4. As can be seen from the above, the hydraulic load-bearing member 9 is always within the range of the hierarchical load-bearing box 4, and the movable end of the hydraulic lifting platform 11 can extend out of the hierarchical load-bearing box 4 to be able to abut against and support the load-bearing device.

[0045] In one embodiment, as Figure 7As shown, it further includes a pressure-bearing member loading cylinder 7, and the pressure-bearing member loading cylinder 7 can be a cylindrical cylinder that is hollow and has a disc-shaped space at the bottom. The hydraulic load-bearing member 9 is clamped in the pressure-bearing member loading cylinder 7. One or more annular ridges can be provided on the inner diameter side of the pressure-bearing member loading cylinder 7, and an annular groove can be provided on the outer diameter side of the hydraulic load-bearing member 9. The annular ridge and the annular groove cooperate to fix the hydraulic load-bearing member 9. The pressure-bearing member loading cylinder 7 is used to protect the hydraulic load-bearing member 9, and the movable end of the hydraulic load-bearing member 9 can extend out of the pressure-bearing member loading cylinder 7 to ensure the normal operation of the hydraulic load-bearing member 9.

[0046] In one embodiment, a loading box arrangement opening 8 is provided on the side of the hierarchical loading box 4. The loading box arrangement opening 8 is arranged on the front of the hierarchical loading box 4 and can be a rectangular hole. The loading box arrangement opening 8 is used for the hydraulic load-bearing member 9 and the pressure-bearing member loading cylinder 7 to enter and exit the hierarchical loading box 4. When adjusting the arrangement quantity and position of the hydraulic load-bearing member 9 and the pressure-bearing member loading cylinder 7 in the hierarchical loading box 4, they can enter and exit through the loading box arrangement opening 8. A moving track 5 is provided on the bottom surface of the hierarchical loading box 4, and positioning points 6 are provided on the moving track 5. The moving track 5 can adopt structural forms such as electromagnetic tracks or mechanical tracks, and the positioning points 6 can adopt structural forms such as electromagnetic points or mechanical positioning. A positioning block 28 is provided at the bottom of the pressure-bearing member loading cylinder 7, and the positioning block 28 is used to move on the moving track 5 and be positioned at the positioning point 6. When using an electromagnetic track and an electromagnetic point, the positioning block 28 can adopt a permanent magnet.

[0047] In one embodiment, the moving track 5 adopts an electromagnetic track. The arrangement path of the electromagnetic track 5 is equidistant cross lines, and the arrangement quantity is 6 longitudinal lines and 6 transverse lines, totaling 12 lines. The positioning point 6 adopts an electromagnetic point, and the electromagnetic point is arranged on the surface of the inner bottom surface of the hierarchical loading box 4, at the intersection of the longitudinal electromagnetic track and the transverse electromagnetic track. Its main function is to provide adsorption positioning for the pressure-bearing member loading cylinder 7 to be in place. There are 6 electromagnetic points in each row, and 6 rows are arranged, totaling 36.

[0048] According to the arrangement method of electromagnetic potential points, the first position in the first row is called No. 1 in the first row, the second position in the first row is called No. 2 in the first row, and so on until the sixth position in the sixth row is called No. 6 in the sixth row. The hydraulic bearing member 9 determines the arrangement level according to the importance of the bearing equipment and the probability of tipping (refer to Table 1 shown). The levels are divided into first level, second level, and third level. Different arrangement methods can be carried out according to different levels to meet different requirements. Moreover, the overall adopts an assembled installation method and can be replaced as the use environment changes later. Among them, the number of hydraulic bearing members 9 arranged at the first level is 8, which are respectively arranged at the positions of No. 3 in the first row, No. 4 in the first row, No. 1 in the third row, No. 6 in the third row, No. 1 in the fourth row, No. 6 in the fourth row, No. 3 in the sixth row, and No. 4 in the sixth row of the electromagnetic potential points.

The arrangement order of the pressure-bearing member loading cylinders 7 is gradually approaching the loading port 8 of the load-bearing box from the end far away from the loading port 8 of the load-bearing box until it is consistent with the arrangement method corresponding to the layout level in step S2. Thus, the pre-setting of the device is completed.

[0058] S4. The hydraulic lifting platforms 11 are defined as A, B, C, and D according to the layout positions. The one at the rear on the left is A, the one at the rear on the right is B, the one at the front on the left is C, and the one at the front on the right is D. According to the layout level described in step S1, select the appropriate number of hydraulic load-bearing members 9 and the corresponding number of pressure-bearing member loading cylinders 7, and assemble the hydraulic load-bearing members 9 and the pressure-bearing member loading cylinders 7 in one-to-one correspondence. Put the assembled pressure-bearing member loading cylinders 7 into the loading port 8 of the load-bearing box, and arrange them in the arrangement order described in step S3 after entering. The arrangement result meets the arrangement positions described in step S2. After the arrangement is completed, connect the hydraulic load-bearing members 9 and the hydraulic lifting platforms 11 with hydraulic pipes 10. The connection correspondence is shown in the following formula:

[0059]

[0060] In the formula: as described in the arrangement order of the intersection points in step S2, x n is the nth row, y m is the mth column, x n y mThat is, the nth row and the mth number. A, B, C, and D respectively correspond to the hydraulic lift table 11 of No. A, the hydraulic lift table 11 of No. B, the hydraulic lift table 11 of No. C, and the hydraulic lift table 11 of No. D. Thus, the device is adapted to the load-bearing equipment.

[0061] S5. Place the load-bearing equipment on the device. The second bearing plate 19 contacts the load-bearing equipment. The load-bearing equipment applies a 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 directly transmits the pressure downward to the 4 hydraulic lift tables 11. The hydraulic lift tables 11 contract under the action of the direct pressure, the height of the hydraulic lift tables 11 decreases, the liquid in the hydraulic lift tables 11 is compressed and flows through the hydraulic pipeline 10 to the hydraulic bearing member 9. At the same time, the inclined telescopic member 20 is vertically compressed as the height of the hydraulic lift tables 11 decreases.

[0062] S6. The hydraulic bearing member 9 receives the liquid pressure transmitted by the hydraulic lift tables 11 through the hydraulic pipeline 10. At the same time, the hydraulic lift tables 11 transmit the direct pressure to the hydraulic bearing member 9 through the first bearing plate 27. The hydraulic bearing member 9 receives the direct pressure transmitted through the first bearing plate 27 from the hydraulic bearing member 9. The direct pressure received by the hydraulic bearing member 9 causes the hydraulic bearing member 9 to contract, and the liquid pressure received by the hydraulic bearing member 9 causes the hydraulic bearing member 9 to elongate. During the process, the direct pressure received by the hydraulic bearing member 9 and the liquid pressure received by the hydraulic bearing member 9 cancel each other out.

[0063] S7. When the direct pressure received by the hydraulic bearing member 9 is greater than the liquid pressure received by the hydraulic bearing member 9, the hydraulic bearing member 9 continues to contract, the overall height of the hydraulic lift tables 11 decreases, the hydraulic lift tables 11 transmit the direct pressure to the hydraulic bearing member 9 through the first bearing plate 27. At the same time, the liquid in the hydraulic bearing member 9 is pressured and flows through the hydraulic pipeline 10 to the hydraulic lift tables 11. The hydraulic lift tables 11 receive the liquid pressure transmitted by the hydraulic bearing member 9 through the hydraulic pipeline 10, the hydraulic lift tables 11 elongate, and the height of the hydraulic lift tables 11 increases to keep the load-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 elongates, the overall height of the hydraulic lift tables 11 increases, the hydraulic bearing member 9 transmits the direct pressure to the hydraulic lift tables 11 through the first bearing plate 27. At the same time, the liquid in the hydraulic lift tables 11 is pressured and flows through the hydraulic pipeline 10 to the hydraulic bearing member 9. The hydraulic bearing member 9 receives the liquid pressure transmitted by the hydraulic lift tables 11 through the hydraulic pipeline 10, the hydraulic lift tables 11 contract, and the height of the hydraulic lift tables 11 decreases until the load-bearing equipment is stable. Thus, the deployment of the load-bearing equipment on the device is completed.

[0064] S8. When the carrying device starts to operate, the carrying device generates vibrations. The vibrations are 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 vibrations increase, the height of the hydraulic lifting platform 11 decreases and transmits the direct pressure to the hydraulic bearing member 9 through the first bearing plate 27. At the same time, the hydraulic lifting platform 11 transmits the liquid pressure to the hydraulic bearing member 9 through the hydraulic pipeline 10. As 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 operation mode of the device, continuously operates with the vibrations generated by the carrying device. When the vibrations decrease, the height of the hydraulic lifting platform 11 rises 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 operation mode of the device, continuously operates with the vibrations generated by the carrying device. Thus, the effect of weakening vibrations is completed, and the carrying device is kept stable.

[0065] S9. When the carrying device has a tipping tendency, the second bearing plate 19 receives an increasing pressure in a single direction, and at the same time, receives a decreasing pressure in the opposite single direction. When the second bearing plate 19 starts to tilt, the tilt expansion member 20 tilts along with the second bearing plate 19. When the degree of tilt gradually increases, the tilt expansion member 20 restricts the second bearing plate 19 from tilting further, causing the second bearing plate 19 to act on the hydraulic lifting platform 11 in the direction of increasing pressure.

[0066] S10. One or more hydraulic lifting platforms 11 in the direction of increasing pressure receive the increased pressure transmitted by the second bearing plate 19. The height of the hydraulic lifting platform 11 decreases and transmits the direct pressure to the hydraulic bearing member 9 through the first bearing plate 27. The hydraulic lifting platform 11 transmits the liquid pressure to the hydraulic bearing member 9 through the hydraulic pipeline 10. At the same time, one or more hydraulic lifting platforms 11 in the direction of decreasing pressure receive the decreased pressure transmitted by the second bearing plate 19. The height of the hydraulic lifting platform 11 rises and receives the direct pressure transmitted by the hydraulic bearing member 9 through the first bearing plate 27. The hydraulic lifting platform 11 receives the liquid pressure transmitted by the hydraulic bearing member 9 through the hydraulic pipeline 10.

[0067] S11. In the direction of increasing pressure, the hydraulic bearing member 9 receives the direct pressure transmitted by the hydraulic lifting platform 11 through the first bearing plate 27, and receives the liquid pressure transmitted by the hydraulic lifting platform 11 through the hydraulic pipeline 10. The direct pressure and the liquid pressure in the hydraulic bearing member 9 cancel each other out. As the direct pressure is continuously applied in the hydraulic bearing member 9, the liquid pressure continuously increases until the direct pressure transmitted by the hydraulic lifting platform 11 received by the hydraulic bearing member 9 through the first bearing plate 27 gradually decreases. Thus, the anti-tipping action of the loading device of the device is completed.

[0068] 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.

[0069] 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.
