Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shockproof, especially relates to a five-layer hyperbolic rail shock insulation platform. BACKGROUND

[0002] Earthquake is a sudden natural disaster, and a major earthquake can cause very 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 shockproof device is a device installed at the bottom of a cultural relic or a cultural relic display cabinet, which effectively absorbs seismic waves under the action of an earthquake, thereby isolating seismic waves and protecting cultural relics. The secondary dimension shock insulation platform is a floating plate that can slide horizontally. When an earthquake only shakes horizontally, the effect of free shock can be achieved. The two plates of the shock insulation platform are equipped with universal sliding devices. The bottom plate is fixed in the display cabinet, and the floating plate can slide left and right with the shaking of the earthquake. This can prevent cultural relics or precision instruments placed on the floating plate from falling over or sliding.

[0003] The utility model patent with the patent publication number CN214364094U is the applicant's prior application patent, which discloses a double-curved surface shock absorption and isolation platform. In the technical solution of the patent, the upper and lower ends of the support column are in contact with the lower curved surface groove and the upper curved surface groove through the curved convex heads, achieving double-curved surface contact and increasing the area of the contact points. In addition, the rolling friction is changed to sliding friction, which increases the resistance of relative motion and avoids the floating plate from shaking with the exhibited cultural relics due to accidental collisions or vibrations, ensuring that the exhibited cultural relics present a stable visual perception. However, in the technical solution of the patent, the horizontal movement of the floating plate during an earthquake cannot effectively drive the movement of the support frame, so the actual damping effect of the double-curved surface is not ideal. Moreover, the point contact sliding friction is prone to wear and tear due to high friction resistance, and the reset is not smooth.

[0004] Therefore, there is a need to develop a five-layer hyperbolic rail shock insulation platform to address the above-mentioned deficiencies. UTILITY MODEL CONTENTS

One roller layer 4 is in rolling contact between the first curve rail 102 and the third curve rail 503 arranged in pairs.

[0036] The top plate 6 top surface places cultural relics, and is provided with a threaded hole for fixing cultural relics.

[0037] The five-layered plate-shaped structure of the bottom plate 1, the roller layer 4, the middle plate 5 and the top plate 6 is stacked together, the layers slide in one direction, and the movement range of the top plate 6 in any horizontal direction is reduced after the two vertical directions are combined, so that the earthquake wave in the horizontal direction is buffered and the cultural relics are protected; the roller layer 4 is clamped by the pair of curved tracks, and the cultural relics are reset by the weight, and a large eccentric displacement is obtained, so that the isolation work requirement of large amplitude is met. The five-layered double curved track isolation platform of the utility model is isolated by the five-layered plate-shaped stacked structure, and the roller layer is clamped by the two oppositely arranged curved tracks, so that the weight of the cultural relics is effectively utilized for smooth resetting.

[0038] In a specific embodiment of the utility model, as shown in Figure 3 and Figure 4 , the rolling contact surface of the first curved track 102 and the roller layer 4 is two identical concave arc track surfaces, and the two concave arc track surfaces are connected together. Similarly, the shape and structure of the second curved track 502, the third curved track 503 and the fourth curved track 602 are consistent with those of the first curved track 102.

[0039] Obviously, the above-mentioned curved track can also adopt a longer concave arc track surface, at which time the diameter of the arc surface of the concave arc track surface needs to be increased.

[0040] Specifically, the roller layer 4 comprises a square frame and a roller assembly, and four roller assemblies are symmetrically installed on the outer side of the wide side of the square frame. The square frame is a frame member which is assembled by bolts. The roller assembly is in rolling contact with the bottom plate 1, the middle plate 5 and / or the top plate 6, that is, the roller assembly is in rolling contact between the pair of curved tracks, and one roller assembly is placed at one concave arc track surface.

[0041] Specifically, as shown in Figure 5 and Figure 8 , the roller assembly comprises a roller mounting shaft 401, an inner roller 402 and an outer roller 403. The root of the roller mounting shaft 401 is provided as a screw rod and is locked on the horizontal side of the square frame by a nut, and the inner roller 402 and the outer roller 403 which are of the same specification are coaxially assembled at the cantilever end of the roller mounting shaft 401. The inner roller 402 is in rolling contact with the inner curved track, and the outer roller 403 is in rolling contact with the outer curved track, that is, the inner roller 402 and the outer roller 403 rotate concentrically and asynchronously when rolling.

[0042] Two said concave arc rail surfaces are connected together synchronously to support two said roller assemblies on the same side, and the horizontal parallel relationship between the spacing plate structures is always maintained; four said roller assemblies arranged between two adjacent plate structures ensure the stability of the structure; the inner roller 402 and the outer roller 403 rotate concentrically and asynchronously when rolling, so that the upper and lower said concave arc rail surfaces do not interfere with each other when the said roller assemblies are clamped therebetween.

[0043] In a specific embodiment of the present application, as shown in Figures 1-8 The five-layer hyperbolic rail seismic isolation platform also comprises a guide limiting assembly arranged on the upper and lower sides of the roller layer 4 to play a sliding guide and anti-disengagement role.

[0044] Specifically, as shown in Figures 1-8 The number of said guide limiting assemblies arranged on each roller layer 4 is eight sets, four sets of which are used to prevent disengagement with the lower component, and the other four sets are used to prevent disengagement with the upper component.

[0045] Specifically, as shown in Figures 1-8 The guide limiting assembly comprises a sliding block 2 and a limiting screw 3, and the limiting screw 3 comprises a screw cap, a light column segment and a screw rod segment arranged coaxially. The side of the bottom plate 1, the intermediate plate 5 and the top plate 6 facing the roller layer 4 is provided with a linear guide rail parallel to the curve rail of the same mounting surface. A limiting plate is arranged on the frame of the roller layer 4, and a through hole is vertically formed in the cantilever end of the limiting plate. The sliding block 2 is slidably connected to the linear guide rail, the screw rod segment of the limiting screw 3 is threadedly connected to the distal end of the sliding block 2, and the light column segment of the limiting screw 3 is guided to pass through the through hole of the limiting plate.

[0046] Specifically, as shown in Figure 5 The limiting plate comprises four inner limiting plates 405 and four outer limiting plates 404 arranged inside the square frame of the roller layer 4. The inner limiting plates 405 and the outer limiting plates 404 are symmetrically arranged about the central axis of the roller layer 4.

[0047] Specifically, as shown in Figure 4 , Figure 6 and Figure 7 The linear guide rail comprises a first linear guide rail 101, a second linear guide rail 501, a third linear guide rail 504 and a fourth linear guide rail 601. Two first linear guide rails 101 are fixed on the top surface of the bottom plate 1 by screws and are parallel to the first curve rail 102. The second linear guide rail 501 and the third linear guide rail 504 are arranged on the bottom surface and the top surface of the intermediate plate 5 respectively, and the second linear guide rail 501 and the third linear guide rail 504 are arranged vertically. Two fourth linear guide rails 601 are fixed on the bottom surface of the top plate 6 by screws and are parallel to the fourth curve rail 602.

[0048] Obviously, the guide limiting assembly can also adopt the cooperation mode of a guide rod, a guide sleeve and a limiting screw 3, and the arrangement structure is consistent with the above-mentioned linear guide rail, except that the strength of the guide rod is lower and the stability is poorer. Similarly, the simple replacement mode falls within the protection scope of the utility model.

[0049] The guide limiting assembly is additionally arranged on the upper and lower sides of the roller layer 4 to play the roles of cooperating with the curved rails to slide and guide and prevent the curved rails from being separated from the roller assembly; the linear guide rail is used for guiding to prevent the concave arc rail surface from being dislocated and separated from the roller assembly; the light column section of the limiting screw 3 is vertically guided and limited with the through hole of the limiting plate to prevent the overturning between the plate structures.

[0050] In a specific embodiment of the utility model, as shown in Figure 4 , Figure 6 and Figure 7 , the five-layer double curved rail shock isolation platform further comprises limiting blocks, and the bottom plate 1, the middle plate 5 and the top plate 6 are centrally provided with the limiting blocks on the side facing the roller layer 4. The limiting blocks limit the frame of the roller layer 4 from inside to prevent it from being excessively displaced and separated.

[0051] Specifically, the limiting blocks are made of rubber blocks. The limiting blocks comprise a first limiting block 103, a second limiting block 504 and a third limiting block 603. The first limiting block 103 is installed on the central position of the top surface of the bottom plate 1 through a screw, the two second limiting blocks 504 are respectively installed on the central positions of the bottom surface and the top surface of the middle plate 5 through screws, and the third limiting block 603 is installed on the central position of the bottom surface of the top plate 6 through a screw.

[0052] The limiting blocks can prevent the roller layer 4 from being separated from the curved rails when it is excessively displaced, and ensure that the two curved rails can relatively roll the roller assembly. The limiting blocks are made of rubber blocks, which can buffer the frame of the roller layer 4 in the extreme case to prevent hard impact.

[0053] The utility model discloses a five-layer double-curved rail shock insulation platform working principle: bottom plate 1 horizontal installation is in the datum cabinet board or exhibition stand top plate, and the cultural relics are placed on the top surface of top plate 6. When the earthquake occurs, bottom plate 1 shakes under the influence of earthquake, and the roller layer 4 of bottom part guides and rolls in X axle direction, and the roller layer 4 of top part guides and rolls in Y axle direction, and after the compound of two vertical directions, the moving amplitude of top plate 6 in horizontal direction can be reduced, and the seismic wave of shock absorption horizontal direction amplitude is buffered, and the cultural relics are protected. When the intermediate plate 5 moves in X axle direction, the outer roller 403 of bottom roller layer 4 rolls on the first curved rail 102, when the amplitude is bigger, the first limiting block 103 contacts the square frame inner side of roller layer 4, and the inner roller 402 relatively rolls on the concave arc rail surface of third curved rail 503, and the limit of amplitude is that the second limiting block 504 of the bottom surface of intermediate plate 5 contacts the square frame inner side of roller layer 4. At the same time, the guiding limiting assembly on the roller layer 4 of bottom part plays the role of auxiliary sliding guide and anti -drop. The light column section of limiting screw 3 and the through -hole of limiting plate carry out vertical direction guiding and limiting, avoid that intermediate plate 5 overturns relative to bottom plate 1. The movement of top plate 6 relative to intermediate plate 5 in Y axle direction is similar with the above process, and will not be repeated here. After the earthquake stops, under the gravity of cultural relics, the inner roller 402 and the outer roller 403 are reset to the most concave part along the curved rail, and the height of the whole device is lowest at this time.

[0054] In summary, the five-layer double-curved rail isolation platform, through the five-layer plate structure of the bottom plate 1, the roller layer 4, the middle plate 5 and the top plate 6 stacked together, the one-way guiding sliding between the layers, the movement range of the top plate 6 in the horizontal direction can be reduced after the two vertical directions are combined, the seismic wave in the horizontal direction is buffered and resisted, and the cultural relics are protected; the roller layer 4 is clamped by the pair of curved rails, and the large eccentric displacement amount can be obtained while resetting by the weight of the cultural relics, and the large amplitude isolation work requirement is met. The five-layer double-curved rail isolation platform is isolated by the five-layer plate structure, and the roller layer is clamped by the two oppositely arranged curved rails, so that the weight of the cultural relics can be effectively utilized for smooth resetting. In addition, the two identical concave arc rail surfaces are connected together to support the two roller assemblies on the same side synchronously, and the horizontal parallel relationship between the spacer plate structures is always maintained; four roller assemblies are arranged between the adjacent two plate structures to ensure the stability of the structure; the inner roller 402 and the outer roller 403 rotate concentrically and asynchronously when rolling, so that the upper and lower concave arc rail surfaces clamp the roller assemblies without interfering with each other. The guide limiting assembly is additionally arranged on the upper and lower sides of the roller layer 4 to play the role of sliding guiding and anti-disengagement with the curved rails; the straight linear guide is used for guiding to prevent the concave arc rail surface and the roller assembly from disengaging; the light column section of the limiting screw 3 and the through hole of the limiting plate are used for vertical direction guiding and limiting to prevent the overturning between the plate structures.

The limiting block is made of rubber block, which can buffer the frame of the roller layer 4 in the extreme case to prevent hard impact.
