Cross shockproof platform

technical field

The present invention relates to a cross anti-shock platform, in particular to a structural design of two linear sliding slides that move in alternating vertical directions, so that the anti-shock platform can effectively reduce the transmission of earthquake force to the application of shock isolation equipment.

Background technique

Seismic activity is mainly the vibration caused by the release of energy from the earth's crust. It is one of the major natural disasters on the earth. Once the intensity of the earthquake reaches a certain level, it will often cause huge property losses and casualties to human beings. Most of the main causes of property damage and casualties are the collapse of buildings and the dumping of heavy furniture. Even if the buildings do not collapse, once the cabinets or shelves for displaying items in the house fall, in addition to causing people in the house to be affected by the cabinets, shelves or In addition to being crushed or smashed by objects, many other goods, collectibles or high-priced artworks are also at risk of damage.

For this reason, in Japan, a country most frequently affected by earthquake disasters, its related industry once designed a kind of shock-absorbing structure specially designed for the shock-absorbing function of buildings, such as Japanese Patent Application Laid-Open No. 8-240033 "Earthquake-proof Structure" patent As shown, it is used to bear the bottom of the building, offset the horizontal shaking force when the earthquake occurs, prevent the pillars of the building from breaking during the shaking process, and achieve the effect of improving the earthquake resistance of the building. The shock-absorbing structure is mainly to install an anti-seismic device between the pillar and the base column. The anti-seismic device is made of overlapping multi-layer steel plates and plastics, so that the bottom of the anti-seismic device is fixed on the base column, and the top of the anti-seismic device is It is fixed at the bottom of the column, so as to counteract the horizontal shaking force during the earthquake.

Second roller guide grooves 132 , 142 .

The two guide rails 2 are bar-shaped bodies, as shown in Figures 1 to 4, one side of which is provided with two protruding rails 21 respectively slidably socketed in the rail grooves 13, 14 of the slide body 1, each of which protruding rails 21 There is more than one third roller guide groove 211 corresponding to the first roller guide groove 131, 141 on the top surface of the top surface, and each of the two sides of the raised rail 21 has a fourth roller guide groove corresponding to the second roller guide groove 132, 142. Roller guide groove 212 .

The retainer 3 is a stamped metal plate or an injection-molded plastic plate, as shown in Figure 1, Figure 2 and Figure 5, so that the retainer 3 can be sleeved on the convex rail 21 of the guide rail 2 and the Between the rail grooves 13 and 14 of the slide body 1, the top of the retainer 3 is provided with a plurality of first limiting holes 31 aligned corresponding to the first roller guide grooves 131 and 141, and the retainer 3 Two sides are provided with a plurality of second position-limiting holes 32 corresponding to the second roller guide grooves 132 and 142 . Wherein, the edges of the first limiting hole 31 and the second limiting hole 32 are respectively provided with a plurality of limiting portions 311 , 321 for limiting the rollers 4 , 5 .

The plurality of rollers 4, 5 are cylinders, as shown in Fig. 1, Fig. 2 and Fig. 5, wherein the rollers 4 are respectively rotatably embedded in the first limiting holes 31 at the top of the retainer 3, the The rollers 5 are respectively rotatably embedded in the second limiting holes 32 on both sides, and the balls 4 are respectively arranged between the first roller guide grooves 131 , 141 and the third roller guide groove 211 Rolling, and the rollers 5 are respectively arranged between the second roller guide groove 132, 142 and the fourth roller guide groove 212 on both sides to roll, thereby forming the cross anti-vibration platform of the present invention, so that the two guide rails 2 can relatively slide on the upper end surface and the lower end surface of the slider body 1.

As shown in Figure 1, Figure 2 and Figure 5, the first roller guide grooves 131, 141 of the slider body 1 and the third roller guide groove 211 of the guide rail 2 are preferably implemented as rectangular roller guide grooves. Groove, so that each of the rollers 4 is horizontally arranged between the first roller guide groove 131, 141 and the third roller guide groove 211, the cross anti-vibration platform of the present invention has the effect of bearing heavy loads in the vertical direction. The second roller guide groove 132, 142 of the above-mentioned slider body 1 and the fourth roller guide groove 212 of the guide rail 2 are preferably implemented as V-shaped roller guide grooves, and the above-mentioned rollers 5 are axially formed. Centers are arranged in a 90-degree staggered manner in the second limiting hole 32 of the cage 3, so the rollers 5 are arranged in a 90-degree staggered axis between the second roller guide grooves 132, 142 and the fourth roller. Roll between the column guide grooves 212, so that the cross anti-vibration platform of the present invention has the effect of bearing vertical load and horizontal load at the same time, and can also prevent the slide body 1 and the guide rails 2 from being separated due to vibration.

As shown in Fig. 1 and Fig. 2 again, above-mentioned each guide rail 2 is preferably implemented with a fixed plate 22, and the above-mentioned protruding rail 21 is assembled or processed on one side of the fixed plate 22, and can be mounted on the fixed plate 22.

The fixed plate 22 of the guide rail 2 on the lower end surface is fixed on the base column or the ground.

In addition, referring to Fig. 3 and Fig. 4, in order to protect the roller groove, the retainer 3 and the rollers 4, 5 of the cross anti-vibration platform of the present invention, the slide body 1 and the two guide rails 2 are kept sliding precisely. A dustproof cover 6 can be respectively implemented on the two guide rails 2, and the dustproof cover 6 can be formed by a plurality of X-shaped protective covers 61 which are movably socketed with each other, or formed by a X-shaped 100-fold dust cover, so One end or a selected part of the dust cover 6 is combined with the guide rail 2, and the other end is combined with the slide body 1, so that the effect of dustproof and maintaining the precision of the cross shockproof platform can be achieved, and it will not affect the slide body 1 and the second. Anti-vibration function of sliding between guide rails 2.

When the present invention is applied as an anti-seismic structure of a building, the guide rail 2 below the slider body 1 is fixedly combined with the foundation or a beam column, and the guide rail 2 above the slider body 1 is fixedly combined with the column or beam of the building, so that The beams or columns of the building are movably connected with the foundation or the beams and columns of the lower floor through cross slides. And a plurality of cross anti-vibration platforms of the present invention can be arranged at even points of the building, so that the weight of the building itself can be distributed to each cross anti-vibration platform to bear evenly. When an earthquake occurs, the foundation of the building or the beams and columns on the lower floor will sway under the influence of the shock wave, and the cross slide table attached to the building can exert a smooth and guided reverse displacement to offset and balance the displacement of the shock wave , so that the building is not affected by the shaking effect of the earthquake. Similarly, the present invention is applied under precision machinery or furnishings (such as high-priced wine cabinets, antique cabinets, etc.), and can also achieve the safety effect of preventing damage caused by earthquakes.

The above-mentioned embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention. The protection scope of the present invention shall be determined by the claims.
