Description

Technical Field

[0001] The invention relates to the field of shockproof technology, and in particular to a shock-absorbing base of an adjustable damping cultural relic cabinet and a working method thereof. Background Art

[0002] Earthquakes are sudden natural disasters. Large earthquakes can cause extremely serious damage. Since humans cannot accurately predict the occurrence of earthquakes, it is particularly important to prevent and mitigate earthquake disasters. The existing cultural relic seismic isolation platform is often installed in the cultural relic display cabinet, supported at the bottom of the cultural relic, and effectively absorbs seismic waves under the action of an earthquake, thereby isolating seismic waves and protecting the cultural relic. However, the existing shock absorption strategies often ignore the shock absorption protection of the cultural relic cabinet. If the cultural relic cabinet collapses, even if the cultural relic seismic isolation platform is effective, it is impossible to protect the collapsed cultural relic.

[0003] The invention patent with the patent publication number CN116326963A discloses a cultural relic cabinet with three-dimensional seismic isolation and anti-overturning protection functions for cultural relics. In this technical solution, the shock-absorbing and supporting device at the bottom of the cultural relic cabinet provides vertical protection for the cultural relics to resist the longitudinal waves of the earthquake. However, practice has shown that the shear waves generated during earthquakes are the most destructive. In this technical solution, the shear waves of the cultural relic cabinet as a whole are not damped and isolated. In the event of a strong earthquake, the shear waves of the earthquake will cause the cultural relic cabinet to shake left and right, front and back, causing the cultural relic cabinet to overturn, and then causing damage to the cultural relics.

[0004] Therefore, it is necessary to develop a shock-absorbing base of an adjustable damping cultural relics cabinet and a working method thereof in view of the above-mentioned defects. Summary of the invention

[0011] Furthermore, two roller grooves are provided on the top surface of the lower track plate, and the roller grooves are provided along the long side direction of the lower track plate. The two roller grooves are staggered along the width direction of the lower track plate and are respectively located at both ends; the two roller components corresponding to the lower track plate are also staggered along the width direction of the lower track plate and roll in the two roller grooves respectively; the upper track plate has the same structure as the lower track plate, except that the working roller guide groove surface is on the bottom surface.

[0012] Furthermore, the bottom surface of the roller groove is an arc surface with a lower middle and higher sides.

[0033] In a specific embodiment, Figures 1 to 7 As shown, the adjustable damping cultural relic cabinet shock-absorbing base of the present invention comprises a bottom plate 1, an intermediate plate 2, a top plate 3, a lower track plate 4, an upper track plate 5, a roller assembly and a damping block 8. The bottom plate 1, the intermediate plate 2 and the top plate 3 are stacked horizontally from bottom to top, and two lower track plates 4 are horizontally symmetrically arranged at the left and right ends of the top surface of the bottom plate 1, four groups of roller assemblies are installed on the bottom surface of the intermediate plate 2 and slide along the lower track plate 4 in front and back directions, and one lower track plate 4 is equipped with two groups of roller assemblies. Two upper track plates 5 are horizontally symmetrically arranged at the front and back ends of the bottom surface of the top plate 3, and another four groups of roller assemblies are installed on the top surface of the intermediate plate 2 and slide along the upper track plate 5 in the left and right directions, and one upper track plate 5 is equipped with two groups of roller assemblies. The guiding directions of the lower track plate 4 and the upper track plate 5 are perpendicular to each other. The damping block 8 is installed at one end of the roller assembly and can adjust the damping size to affect the rolling resistance of the roller assembly. The top surface of the top plate 3 is provided with mounting threaded holes 301 for mounting the cultural relic cabinet, that is, the legs of the cultural relic cabinet are mounted through the mounting threaded holes 301 .

[0034] By arranging a bottom plate 1, a middle plate 2 and a top plate 3 stacked together at the bottom of the cultural relic cabinet, and arranging guide rolling elements on the upper and lower surfaces of the middle plate 2, horizontal earthquake resistance is achieved; by arranging a damping block 8 capable of adjusting the damping size at one end of the roller assembly, the adjustment of earthquake damping is achieved, which is better suitable for local earthquake conditions. The adjustable damping cultural relic cabinet shock-absorbing base of the present invention adopts a three-plate stacked horizontal earthquake isolation mechanism, which can effectively reduce the damage to the cultural relic cabinet caused by earthquakes.

[0035] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, the middle plate 2 is provided with a clearance opening 201 at the installation position of the roller assembly, and the roller assembly and the clearance opening 201 are equal in number and arranged one by one. The eight clearance openings 201 are evenly distributed at the four corners of the middle plate 2, and the clearance openings 201 are rectangular openings.

[0036] By opening a clearance opening 201 on the middle plate 2 for facilitating the installation of the roller assembly, the roller assembly is partially embedded in the middle plate 2, which can reduce the height of the middle part and reduce the height of the entire shock-absorbing base, making the structure more compact and reliable.

[0037] In a specific embodiment of the present invention, Figures 2 to 5As shown, the roller assembly includes a roller member 6 and a bearing seat 7. The roller member 6 is a roller shaft with a roller, and the roller is in rolling contact with the lower track plate 4 or the upper track plate 5. The bearing seat 7 is a T-block support, and the head of the bearing seat 7 is inserted into the clearance opening 201 and rotatably supports the roller shaft. The bottom feet of the bearing seat 7 are connected to both sides of the clearance opening 201 by screws.

[0038] Specifically, if Figures 2 to 5 As shown, one end of the roller shaft protrudes out of the bearing seat 7 and cooperates with the damping block 8 to generate damping force. The damping block 8 is connected to the middle plate 2 through bolts at both ends, and the arc groove in the middle of the damping block 8 is pressed against the shaft end of the roller shaft. The damping block 8 is made of polytetrafluoroethylene material.

[0039] Obviously, the damping block 8 can also be installed at one end of the roller shaft and be coaxially arranged therewith, so as to achieve the damping effect on the roller shaft by directly contacting the end face of the roller shaft.

[0040] The damping adjustment of the damping block 8 on the axial end of the roller shaft is achieved by tightening the mounting screws at both ends of the damping block 8. The structure is simple and reliable, and the adjustment is easy to achieve.

[0041] In a specific embodiment of the present invention, Figure 5 and Figure 7 As shown, the top surface of the lower track plate 4 is provided with two roller grooves 402, which are provided along the long side of the lower track plate 4. The two roller grooves 402 are staggered along the width direction of the lower track plate 4 and are respectively located at both ends. The two roller components 6 corresponding to the lower track plate 4 are also staggered along the width direction of the lower track plate 4 and roll in the two roller grooves 402 respectively. In other words, the rollers of the two roller components 6 on the same lower track plate 4 are staggered front and back, so that the length of the two roller grooves 402 can be increased beyond the central symmetry plane.

[0042] Specifically, if Figure 2 and Figure 3 As shown, the upper rail plate 5 has the same structure as the lower rail plate 4 except that the working roller guide groove surface is arranged on the bottom surface.

[0043] Specifically, if Figure 5 and Figure 7 As shown, the bottom surface of the roller groove 402 is an arc surface, and the roller groove 402 is lower in the middle and higher on both sides.

[0044] By providing two parallel staggered roller grooves 402 on the top surface of the lower track plate 4, the rolling length of the two rollers is increased, that is, the anti-seismic guide stroke is increased, and it can also adapt to earthquakes with large amplitudes. By providing a concave arc surface on the bottom surface of the roller groove 402, the middle plate 2 and the top plate 3 can be automatically centered under the self-weight drive of the cultural relics cabinet.

[0045] In a specific embodiment of the present invention, Figures 2 to 6 As shown, the adjustable damping cultural relics cabinet shock-absorbing base of the present invention also includes a limiting structure, which is arranged between the middle plate 2 and the lower track plate 4 and / or the upper track plate 5 to limit the displacement of the middle plate 2 and the top plate 3.

[0046] Specifically, if Figures 4 to 6 As shown, the limiting structure includes a limiting block 9, the root of which is installed on the middle plate 2 by screws, and a limiting head 901 is provided at the outer end of the limiting block 9, and the limiting head 901 protrudes to one side. A limiting groove 1 401 is provided at the bottom of the long outer wall of the lower track plate 4, and a limiting groove 2 501 is provided at the top of the long outer wall of the upper track plate 5. The limiting head 901 is slidably engaged in the limiting groove 1 401 or the limiting groove 2 501.

[0047] Specifically, if Figure 4 and Figure 6 As shown, the surfaces where the limiting groove 1 401 and the limiting groove 2 501 contact the limiting head 901 are arc surfaces, and the corresponding sliding contact surface of the limiting head 901 is also set as a cylindrical surface.

[0048] By setting the limiting structure between the middle plate 2 and the track plate, the displacement of the middle plate 2 and the top plate 3 is limited to avoid overturning of the cultural relics cabinet due to excessive displacement; the limiting head 901 of the limiting block 9 is matched with the limiting groove on the track plate to achieve displacement limitation and a stable and reliable structure; the limiting groove is set as an arc surface to adapt to the bottom surface of the roller groove 402 as an arc surface, so as to avoid the middle plate 2 and the top plate 3 from being horizontally displaced and the limiting head 901 being stuck during the process of lifting the height.

[0049] In a specific embodiment of the present invention, Figures 1 to 4 As shown, the adjustable damping cultural relic cabinet shock-absorbing base of the present invention also includes a panel 10, threaded holes are opened on the surrounding walls of the middle plate 2, and the panel 10 of the whole circle is connected by countersunk screws. The panel 10 is provided with a track clearance opening 1001 at the end position of the lower track plate 4 and the upper track plate 5.

[0050] Specifically, the enclosure 10 includes four side panels, each of which is mounted on the side wall of the middle panel 2 by countersunk screws. The inner side wall of the side panel is provided with a mounting groove adapted to the middle panel 2.

[0051] By adding the enclosure panels 10 on the surrounding walls of the middle panel 2, the internal structure of the shock-absorbing base can be effectively protected and the appearance can be improved.

[0052] The working principle of the adjustable damping shock-absorbing base of the cultural relic cabinet of the present invention is as follows: in a normal state, the bottom plate 1, the middle plate 2 and the top plate 3 are automatically aligned without relative displacement. The legs of the cultural relic cabinet are installed on the top plate 3 by screws. Under the action of the deadweight of the cultural relic cabinet and the cultural relics inside it, the roller of the roller member 6 is always at the lowest point of the roller groove 402, so that the height of the shock-absorbing base is the lowest and the most stable state. When an earthquake occurs, under the influence of the seismic shear wave, the cultural relic cabinet undergoes horizontal displacement in the front-back or left-right direction relative to the bottom plate 1, the top plate 3 moves with the cultural relic cabinet, and the middle plate 2 cooperates to make corresponding horizontal movement. This adaptive displacement reduces the destructive effect of the earthquake force on the cultural relic cabinet. After the earthquake, under the action of the deadweight of the cultural relic cabinet and the cultural relics inside it, the roller of the roller member 6 returns to the lowest point of the roller groove 402, so that the height of the shock-absorbing base is the lowest and returns to a stable state.

[0053] In summary, the adjustable damping shock-absorbing base of the cultural relic cabinet of the present invention is realized by arranging a bottom plate 1, a middle plate 2 and a top plate 3 stacked together at the bottom of the cultural relic cabinet, and arranging guide rolling elements on the upper and lower surfaces of the middle plate 2 to achieve horizontal earthquake resistance; by arranging a damping block 8 capable of adjusting the damping size at one end of the roller assembly, the adjustment of the earthquake damping is realized, which is better suitable for local earthquake conditions. The adjustable damping shock-absorbing base of the cultural relic cabinet of the present invention adopts a three-plate stacked horizontal seismic isolation mechanism, which can effectively reduce the damage to the cultural relic cabinet caused by earthquakes. In addition, by opening a clearance port 201 on the middle plate 2 to facilitate the installation of the roller assembly, the roller assembly is partially embedded in the middle plate 2, which can reduce the height of the middle part, realize the reduction of the height of the entire shock-absorbing base, and the structure is more compact and reliable. The damping adjustment of the damping block 8 on the shaft end of the roller shaft is realized by tightening the mounting screws at both ends of the damping block 8. The structure is simple and reliable, and it is easy to adjust. By setting two parallel staggered roller grooves 402 on the top surface of the lower track plate 4, the rolling length of the two rollers is increased, that is, the anti-seismic guide stroke is increased, and it can also adapt to earthquakes with large amplitudes. By setting a concave arc surface on the bottom surface of the roller groove 402, the middle plate 2 and the top plate 3 can be automatically centered under the self-weight drive of the cultural relics cabinet. By setting the limiting structure between the middle plate 2 and the track plate, the displacement of the middle plate 2 and the top plate 3 is limited to avoid the overturning of the cultural relics cabinet after excessive displacement; the limiting head 901 of the limiting block 9 is matched with the limiting groove on the track plate to achieve displacement limitation, and the structure is stable and reliable; the limiting groove is set as an arc surface, which is adapted to the bottom surface of the roller groove 402 as an arc surface, to avoid the situation where the limiting head 901 is stuck during the horizontal displacement and the height lifting process of the middle plate 2 and the top plate 3.

[0055] The working method of the adjustable damping cultural relic cabinet shock-absorbing base of the present invention also adopts a three-plate stacking horizontal seismic isolation mechanism, utilizes longitudinal and transverse guidance to generate horizontal displacement, can effectively isolate earthquake shear waves, and reduce earthquake damage to the cultural relic cabinet.

The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
