Description

TECHNICAL FIELD

[0002] In order to avoid the influence of various mechanical and electrical equipment, cultural relics, electronic precision instruments and other equipment by earthquakes, it is necessary to install them in the shock insulation device, which can buffer the earthquake force and avoid damage to such equipment caused by earthquakes. The existing shock insulation device uses a linear slide rail structure for shock insulation. For example, the patent with publication number CN102483123A discloses a shock insulation platform with damping mechanism and a shock insulation device using the same. The intermediate plate is used to realize the orthogonal connection of the two slider + slide rail structure, and a spring and other damping devices are added in the middle to play a resetting role, so as to achieve good shock insulation effect during earthquakes.

[0003] However, such structure has obvious defects: (1) the upper and lower plates in such structure are large, which increases the weight of the shock insulation device and the difficulty of installation, and is prone to assembly errors; (2) the support center of gravity of such structure is easy to exceed the support range of the whole device, resulting in poor stability of the whole device structure and easy overturning danger; (3) the bearing capacity of such structure is poor; (4) the shock absorption capacity of such structure is poor, and it is difficult to offset the influence of large earthquake energy on the equipment above.

[0004] Therefore, some shock insulation devices in the prior art are designed by the position relationship between the upper and lower plates and the slide rail and slider to reduce the risk of overturning of the shock insulation device; double parallel orthogonal guide rails can also be used to increase the shock insulation effect of the shock insulation device.

[0058] As Figures 1 to 23 shown, in order to solve the existing shock isolation device is limited by structure, cannot realize good bending resistance, anti-overturning capacity, and the existing shock isolation device weak bearing capacity, therefore the utility model provides a kind of linear slide rail type shock isolation device based on staggered support, it utilizes the characteristics of linear slide rail low friction coefficient, the conduction of seismic force is isolated, and the utility model is supported by multiple staggered points, it can provide larger bearing capacity, and can provide stronger bending resistance, anti-overturning capacity for the upper equipment in earthquake.

[0059] The utility model can be applied to cloud computing, the Internet, supercomputing centers, banks, transportation, medical treatment, education, military, museums, nuclear power plants, international key scientific laboratories, urban gas pipeline networks, high-speed railway bridges and other fields, and can be used for seismic isolation of precision equipment in data centers, cultural relics, high-precision laboratory equipment, electromechanical equipment, etc.

[0060] Depending on the different upper equipment, the linear slide rail type seismic isolation device based on offset support may include one seismic isolation device or multiple seismic isolation devices, which are arranged in parallel and connected by beams. Figure 1 As shown, when multiple isolation devices ( Figure 1 The embodiment shown includes a first seismic isolation device 01 and a second seismic isolation device 02, wherein the plurality of seismic isolation devices are arranged in parallel in the Y-axis direction and connected by a crossbeam 03 in the Y-axis direction, and the upper equipment is mounted on the crossbeam 03. Figure 2 As shown, when a seismic isolation device is used, the upper equipment can be directly installed on the seismic isolation device.

[0061] like Figure 2 、 Figure 3 As shown, the overall length of the seismic isolation device in the X-axis direction of the present invention is greater than its overall width in the Y-axis direction, allowing it to be applied to upper equipment with a rectangular bottom surface. In this case, the displacement distances required to meet the upper equipment's limit values ​​in each direction of motion are equal. In other embodiments, if the upper equipment has a square bottom surface, the overall length of the seismic isolation device in the X-axis direction is equal to its overall width in the Y-axis direction.

[0062] In this embodiment, the length of the X-axis rail assembly 100 in the X-axis direction is greater than the outermost spacing between the two Y-axis rail assemblies in the X-axis direction, the length of the X-axis rail assembly 100 in the X-axis direction is greater than the length of the Y-axis rail assembly in the Y-axis direction, the width of the X-axis rail assembly 100 in the Y-axis direction is less than the outermost spacing between the two Y-axis rail assemblies in the X-axis direction, and the width of the X-axis rail assembly 100 in the Y-axis direction is less than the length of the Y-axis rail assembly in the Y-axis direction. In this way, while cooperating to achieve the support and seismic isolation functions of the upper equipment, the volume and weight of the seismic isolation device can be minimized, and it can also facilitate the installation of cables for the upper equipment.

[0063] like Figures 2 to 5As shown, the shock insulation device comprises an X-axis sliding rail assembly 100 and two Y-axis sliding rail assemblies arranged on the X-axis sliding rail assembly 100, the two Y-axis sliding rail assemblies are spaced from each other, and the two Y-axis sliding rail assemblies are orthogonally arranged with the X-axis sliding rail assembly 100. The shock insulation device can be applied to the upper equipment with the gravity center coinciding with the physical center, and can also be applied to the shock insulation equipment with the gravity center deviating from the physical center. In the utility model, X and Y are two mutually perpendicular directions, that is, the two Y-axis sliding rail assemblies are orthogonal with the X-axis sliding rail assembly 100, and the orthogonal arrangement mode can make the shock insulation device horizontally move in any direction, ensure the stability of the upper equipment, and the movement directions do not interfere with each other.

[0064] In Figures 2 to 5 In the embodiment shown, the X-axis sliding rail assembly 100 comprises a first X-axis sliding rail assembly 100a and a second X-axis sliding rail assembly 100b (the tail end of the first X-axis sliding rail assembly 100a is connected with the head end of the second X-axis sliding rail assembly 100b), and the Y-axis sliding rail assembly comprises a first Y-axis sliding rail assembly 200 and a second Y-axis sliding rail assembly 300, the first Y-axis sliding rail assembly 200 is arranged on the first X-axis sliding rail assembly 100a, and the second Y-axis sliding rail assembly 300 is arranged on the second X-axis sliding rail assembly 100b (the first Y-axis sliding rail assembly 200 and the second Y-axis sliding rail assembly 300 are parallel). The first X-axis sliding rail assembly 100a and the second X-axis sliding rail assembly 100b are symmetric about the Y-direction central axis of the X-axis sliding rail assembly 100, and the two Y-axis sliding rail assemblies are symmetric about the Y-direction central axis of the X-axis sliding rail assembly 100, that is, the first X-axis sliding rail assembly 100a and the second X-axis sliding rail assembly 100b are mirror distributed along the connecting line of the two; the first Y-axis sliding rail assembly 200 and the second Y-axis sliding rail assembly 300 are symmetrically arranged along the connecting point axis of the first X-axis sliding rail assembly 100a and the second X-axis sliding rail assembly 100b. The first X-axis sliding rail assembly 100a, the second X-axis sliding rail assembly 100b, the first Y-axis sliding rail assembly 200 and the second Y-axis sliding rail assembly 300 form a "nian" (nian) character-shaped structure.

[0065] The X-axis sliding rail assembly 100 comprises a bottom plate, the bottom plate is mounted on a working base, and the bottom plate is used for bearing the entire shock insulation device and the upper equipment; the Y-axis sliding rail assembly comprises a top plate, and the top plate is used for bearing the upper equipment. In order to ensure good supporting capacity and smooth effect, the utility model discloses that the upper part of the two Y-axis sliding rail assemblies is provided with a support plate for connecting the upper equipment. In the utility model, the width of the support plate 600 is greater than the width of the bottom plate, through the size design of the support plate 600 and the bottom plate, combined with the "nian" character-shaped design of the entire shock insulation device, the shock insulation device in the utility model has stronger bearing capacity, and when applied to electronic instrument equipment such as mechanical and electrical equipment, the wiring of the cable can be better performed.

[0066] Specifically, because the width of the support plate 600 is greater than that of the base plate, a gap exists between the support plate 600 and the base plate. Electronic equipment can be routed through this gap, and the cables will not affect the sliding of the isolation device, nor will they be easily pulled, derailed, or worn. Furthermore, under the same dimensions, through the design of the support plate 600 and the base plate, combined with the "卄"-shaped design of the entire isolation device, the isolation device of the utility model can increase its load capacity from the industry's highest of 600kg to 1500kg, which helps ensure the safety of the equipment above.

[0067] The slide rails provide a guide for the upper equipment to slide and reset. The X-axis slide rail assembly 100 also includes a first X-axis slide rail 110 and a second X-axis slide rail 120, mounted on the bottom plate. The first and second X-axis slide rails 110 and 120 are arranged side by side. The Y-axis slide rail assembly also includes a first Y-axis slide rail 210 and a second Y-axis slide rail 220, connected to the top plate. The four slide rails intersect, forming a double "卄"-shaped structure.

[0068] In the present invention, one or more of the first X-axis slide rail 110, the second X-axis slide rail 120, the first Y-axis slide rail 210, and the second Y-axis slide rail 220 are linear slide rails with different friction coefficients. Optimally, the first X-axis slide rail 110, the second X-axis slide rail 120, the first Y-axis slide rail 210, and the second Y-axis slide rail 220 are all linear slide rails with different friction coefficients, thereby increasing the seismic isolation device's consumption of seismic energy in all directions. Figure 8 Taking the first X-axis slide rail 110 as an example, the friction coefficient of the surface of the linear slide rail gradually increases from the midpoint of the linear slide rail toward its two ends.

[0069] In addition, as the linear slide extends toward its ends, the lengths corresponding to linear slides with different friction coefficients gradually decrease. In the present invention, by providing different coatings on the surface of the linear slide, a design with a gradual change in the friction coefficient of the linear slide surface is achieved. In other embodiments, other methods can also be used to achieve a design with a gradual change in the friction coefficient.

[0070] The slider and the slide rail are matched with each other, the slider provides movement support for the movement of the upper equipment, and provides a conversion basis for multidirectional sliding. The first Y-axis slide rail 210 and the first X-axis slide rail 110 are connected through the first slider assembly 400, the second Y-axis slide rail 220 and the second X-axis slide rail 120 are connected through the second slider assembly 500, and the two first slider assemblies 400 and the two second slider assemblies 500 are staggered with each other, thereby forming four point positions for staggered support of the top plate and the upper equipment. In the utility model, limited by the first X-axis slide rail 110 and the second X-axis slide rail 120, the two first slider assemblies 400 and the two second slider assemblies 500 enclose an isosceles trapezoid, thereby also ensuring that the gravity center of the upper equipment on the support plate 600 is always located on the central axis between the first Y-axis slide rail assembly 200 and the second Y-axis slide rail assembly 300, and the stress is more balanced.

[0071] The first slider assembly 400 and the second slider assembly 500 each include a slider connecting piece, a lower slider located at the lower side of the slider connecting piece, and an upper slider located at the upper side of the slider connecting piece, and a push rod connecting piece is further arranged on the slider connecting piece, the end of the push rod connecting piece is protruded and connected with the X-axis reset piece 130 / Y-axis reset piece 230 in the X-axis slide rail assembly 100 / Y-axis slide rail assembly, and the reset of the first slider assembly 400 and the second slider assembly 500 is realized through the force of the X-axis reset piece 130 / Y-axis reset piece 230 on the push rod connecting piece. Preferably, the push rod connecting piece includes a push rod connecting part and a push rod swing arm, the push rod connecting part is connected with the slider connecting piece, the push rod swing arm is connected with the X-axis reset piece 130 / Y-axis reset piece 230, and the protrusion design of the push rod swing arm can interact with the X-axis reset piece 130 / Y-axis reset piece 230 without affecting the normal movement of the first slider assembly 400 and the second slider assembly 500.

[0072] Specifically, as shown in Figure 7 , Figure 9 , the first slider assembly 400 is used for connecting the first X-axis slide rail 110 and the first Y-axis slide rail 210, wherein the first slider assembly 400 includes a first slider connecting piece 410, a first lower slider 420 and a first upper slider 430, the first lower slider 420 is assembled at the lower side of the first slider connecting piece 410 and connected with the first X-axis slide rail 110, and the first upper slider 430 is assembled at the upper side of the first slider connecting piece 410 and connected with the first Y-axis slide rail 210. The first push rod connecting part 440 is assembled on the side surface of the first slider connecting piece 410, the outer end thereof is protruded downward to form a first push rod swing arm 441, and the first push rod swing arm 441 is connected with the movable end of the X-axis reset piece 130.

[0073] Specifically, as shown in Figure 7 , Figure 13 , Figure 14As shown, the second slider assembly 500 is used to connect the second X-axis slide rail 120 and the second Y-axis slide rail 220, wherein the second slider assembly 500 includes a second slider connector 510, a second lower slider 520, and a second upper slider 530.

[0074] Through the structural design of the first slider assembly 400 and the second slider assembly 500, the utility model can, on the one hand, more conveniently assemble the slider assembly with the corresponding slide rail assembly, thereby reducing the difficulty of installation; on the other hand, compared with the existing slider assembly upper and lower slider welding connection method, the utility model does not require welding and can be installed and fixed only by bolts, thereby reducing the difficulty of operation. At the same time, it has lower performance requirements for each connecting part and lower requirements for the ability of the assembly workers.

[0075] The first slider assembly 400 and the second slider assembly 500 are both provided with a slider scraper (eg Figure 9 The first slider assembly 400 is connected to the first X-axis rail 110 and the first Y-axis rail 210 via the slider scraper 431, and the second slider assembly 50 is connected to the second X-axis rail 120 and the second Y-axis rail 220 via the slider scraper.

[0076] Preferably, the slider scraper is made of modified polyurethane material, which can also play a role in friction damping: as the relative displacement speed between each slider and the corresponding slide rail increases, the friction damping force rises linearly at a slope of 45 degrees.

[0077] like Figure 6 、 Figure 7 、 Figure 13 As shown, the X-axis reset member 130 is disposed on the base plate and is connected to the first slider assembly 400 to reset the first slider assembly 400. Specifically, when the first slider assembly 400, together with the Y-axis rail assembly, and the upper equipment, is affected by an earthquake or other vibration and deviates from the equilibrium position of the first slider assembly 400 on the X-axis, the X-axis reset member 130 drives the first slider assembly 400, together with the Y-axis rail assembly, and the upper equipment, to return to the equilibrium position on the X-axis.

[0078] The Y-axis reset member 230 is disposed on the top plate and is connected to the second slider assembly 500 to reset the second slider assembly 500. Specifically, when the second slider assembly 500, together with the Y-axis rail assembly, and the upper equipment, is affected by an earthquake or other vibration and deviates from the equilibrium position of the second slider assembly 500 on the Y-axis, the Y-axis reset member 230 will reset the second slider assembly 500, together with the Y-axis rail assembly, and the upper equipment, to the equilibrium position on the Y-axis.

[0079] The X-axis slide rail assembly 100 may be provided with an X-axis reset chamber 131 for accommodating the X-axis reset member 130. The X-axis reset chamber 131 is located on the bottom plate and has an opening for the first slider assembly 400 to extend into and connect with the X-axis reset member 130, providing space for the first slider assembly 400 to slide back and forth in the X-direction. The X-axis reset chamber 131 can protect the X-axis reset member 130 within the X-axis reset chamber 131 and provide guidance for the restoring force of the X-axis reset member 130. Similarly, the Y-axis slide rail assembly may also be provided with a Y-axis reset chamber 231 for accommodating the Y-axis reset member 230. The Y-axis reset chamber 231 is located on the top plate and has an opening for the second slider assembly 500 to extend into and connect with the Y-axis reset member 230, providing space for the second slider assembly 500 to slide back and forth in the Y direction. The Y-axis reset chamber 231 protects the Y-axis reset member 230 within the Y-axis reset chamber 231 and provides guidance for the restoring force of the Y-axis reset member 230. The present invention, through the X-axis reset chamber 131 and the Y-axis reset chamber 231, can also make the structure of the X-axis slide rail assembly 100 and the Y-axis slide rail assembly more compact, and more conveniently assemble the X-axis reset member 130 and the first slider assembly 400, as well as the Y-axis reset member 230 and the second slider assembly 500.

[0080] Preferably, the X-axis reset member 130 may include a first X-axis reset member 130a and a second X-axis reset member 130b, the first slider assembly 400 is located between the first X-axis reset member 130a and the second X-axis reset member 130b, and the first slider assembly 400 is respectively connected to the movable end of the first X-axis reset member 130a and the movable end of the second X-axis reset member 130b, and the fixed end of the first X-axis reset member 130a and the fixed end of the second X-axis reset member 130b are both connected to the X-axis slide rail assembly 100 (referring to the X-axis reset chamber 131, the same below). Similarly, the Y-axis reset member 230 may also include a first Y-axis reset member 230a and a second Y-axis reset member 230b, and the second slider assembly 500 is respectively connected to the movable end of the first Y-axis reset member 230a and the movable end of the second Y-axis reset member 230b, and the fixed end of the first Y-axis reset member 230a and the fixed end of the second Y-axis reset member 230b are both connected to the Y-axis slide rail assembly (referring to the Y-axis reset chamber 231, the same below).

[0081] Based on the above preferred scheme, the fixed end of the first X-axis reset member 130a and the fixed end of the second X-axis reset member 130b in the present invention can directly abut against the X-axis slide rail assembly 100, or can be fixed on the X-axis slide rail assembly 100; the movable end of the first X-axis reset member 130a and the movable end of the second X-axis reset member 130b can directly abut against the first slider assembly 400, or can be fixed on the first slider assembly 400; the fixed end of the first Y-axis reset member 230a and the fixed end of the second Y-axis reset member 230b can directly abut against the Y-axis slide rail assembly, or can be fixed on the Y-axis slide rail assembly; the movable end of the first Y-axis reset member 230a and the movable end of the second Y-axis reset member 230b can directly abut against the second slider assembly 500, or can be fixed on the second slider assembly 500.

[0082] In the present invention, in the initial state, both the X-axis reset member 130 and the Y-axis reset member 230 are springs in a compressed state, and when the first slider assembly 400 moves to the extreme position at one end in the X direction, the X-axis reset member 130 located in the direction of the end is still in a compressed state, and the X-axis reset member 130 on the other side changes from the compressed state to the natural state and remains in the natural state; when the second slider assembly 500 moves to the extreme position at one end in the Y direction, the Y-axis reset member 230 located in the direction of the end is still in a compressed state, and the Y-axis reset member 230 on the other side changes from the compressed state to the natural state and remains in the natural state. On the one hand, the spring in the compressed state can ensure that the support plate 600 and the upper equipment are at the center of the X-axis slide rail assembly 100 and the center of the two Y-axis slide rail assemblies when they are not affected by external forces, so that the upper equipment remains balanced; on the other hand, the spring in the compressed state can prevent the X-axis reset component 130 and the Y-axis reset component 230 from undergoing state changes of "tension state / natural state-compression state" and "compression state-tension state / natural state" when the upper equipment is in an earthquake, thereby affecting the stability of the upper equipment.

[0083] Preferably, the X-axis reset member 130 is located between the first X-axis slide rail 110 and the second X-axis slide rail 120, so that the reset point of the X-axis reset member 130 on the first slider assembly 400 is at the center of the X-axis, making the reset force more balanced. The Y-axis reset member 230 is oriented between the first Y-axis slide rail assembly 200 and the second Y-axis slide rail assembly 300, so that the two first Y-axis reset members 230a and the second Y-axis reset member 230b are opposite each other. The Y-direction reset force on the upper device is closer to the center of the upper device, making the force more stable.

[0084] like Figures 15 to 17 As shown, in another embodiment, the connection relationship of the X-axis reset member and the connection relationship of the Y-axis reset member have different designs. Figures 2 to 14 The difference from the illustrated embodiment is that, in this embodiment, the X-axis reset member 130 is located between the first X-axis slide rail 110 and the second X-axis slide rail 120 , and the Y-axis reset member 230 is located between the first Y-axis slide rail 210 and the second Y-axis slide rail 220 .

[0085] Specifically, the X-axis slide rail assembly 100 is provided with an X-axis reset guide rod 132, and the X-axis reset member 130 is sleeved on the X-axis reset guide rod 132, so that the X-axis reset guide rod 132 guides the X-axis reset member 130; the Y-axis slide rail assembly is provided with a Y-axis reset guide rod 232, and the Y-axis reset member 230 is sleeved on the Y-axis reset guide rod 232, so that the Y-axis reset guide rod 232 guides the Y-axis reset member 230. Through the structure design, on the one hand, the X-axis reset member and the Y-axis reset member can be compressed and rebounded in the specified direction, and on the other hand, the abrasion and noise caused by the friction between the X-axis reset member and the Y-axis reset member and the chamber structure during the compression and rebounding process can be reduced.

[0086] Correspondingly, the push rod swing arm of the slider assembly is provided with a swing arm sliding groove corresponding to the reset guide rod, which can make the push rod swing arm move along the reset guide rod all the time, and the swing arm sliding groove can also form resistance to the X-axis reset member and the Y-axis reset member through the protrusions on both sides of the swing arm sliding groove. Figure 17 As shown in the figure, the end of the first swing arm push rod 441 is provided with a first swing arm sliding groove 4441, and the second swing arm push rod is similar to this structure, which will not be repeated here.

[0087] In order to ensure the safety of the entire shock isolation device and the equipment above, the first X-axis slide rail 1100, the second X-axis slide rail 120, the first Y-axis slide rail 210 and the second Y-axis slide rail 220 are all provided with limiting members at one side / end.

[0088] In one specific embodiment, one end of the first X-axis slide rail 110 in the first X-axis slide rail assembly 100a and the other end of the first X-axis slide rail 110 in the second X-axis slide rail assembly 100b are provided with a first X-axis limiting member 111, the other end of the second X-axis slide rail 120 in the first X-axis slide rail assembly 100a and one end of the second X-axis slide rail 120 in the second X-axis slide rail assembly 100b are provided with a second X-axis limiting member 120, one end of the first Y-axis slide rail 210 in the first Y-axis slide rail assembly 200 and one end of the first Y-axis slide rail in the second Y-axis slide rail assembly 300 are provided with a first Y-axis limiting member 211, and the other end of the second Y-axis slide rail 220 in the first Y-axis slide rail assembly 200 and the other end of the second Y-axis slide rail in the second Y-axis slide rail assembly 300 are provided with a second Y-axis limiting member 221. The eight limiting members limit the four movement directions of the equipment above respectively, so that the two first slider assemblies 400 are limited when moving to the two end limit positions in the X direction, and the two second slider assemblies 500 are limited when moving to the two limit positions in the Y direction.

[0089] The bottom plate, the first X-axis sliding rail 110, the second X-axis sliding rail 120 and the X-axis reset piece 130 in the utility model all extend in X direction, the top plate, the first Y-axis sliding rail 210, the second Y-axis sliding rail 220 and the Y-axis reset piece 230 all extend in Y direction. Since the first Y-axis sliding rail assembly 200 and the second Y-axis sliding rail assembly 300 are mutually symmetrical, the first Y-axis sliding rail 210, the first Y-axis limiting piece 211, the second Y-axis sliding rail 220, the second Y-axis limiting piece 221 and the Y-axis reset piece 230 in the first Y-axis sliding rail assembly 200 and the first Y-axis sliding rail, the first Y-axis limiting piece, the second Y-axis sliding rail, the second Y-axis limiting piece and the Y-axis reset piece in the second Y-axis sliding rail assembly 300 are all symmetrical respectively. Through the design of the structure, the first Y-axis sliding rail assembly 200 and the second Y-axis sliding rail assembly 300 can play more balanced supporting and shock isolation effects on the support plate 600 and the shock isolation device located on the upper side of the support plate 600.

[0090] As shown in Figures 2 to 7 、 Figures 10 to 12 In a preferred embodiment, the shock isolation device further comprises an auxiliary function assembly 610, which is used to lock the state of the shock isolation device without affecting the action of isolated seismic force, so as to avoid the shaking of the upper equipment caused by accidental touch or other small vibration. In the embodiment, the X-axis sliding rail assembly 100 is installed on the working base to realize the fixing effect, the support plate 600 is connected with the upper equipment to realize the buffering of the upper equipment, and therefore the auxiliary function assembly 610 is arranged between the support plate 600 and the X-axis sliding rail assembly 100.

[0091] The auxiliary function assembly 610 comprises a first connecting piece 611 connected with the X-axis sliding rail assembly 100, a second connecting piece 612 connected with the support plate 600, and a limiting pin 613 passing through the second connecting piece 612 and being in limiting connection with the first connecting piece 611, wherein the first connecting piece 611 and the second connecting piece 612 have a gap therebetween, and the limiting pin 613 can abut against the first connecting piece 611 after passing through the second connecting piece 612. The first connecting piece 611 can be installed in a free position of the X-axis sliding rail assembly 100 having an installation space, so that the space can be fully saved, and the second connecting piece 612 can be connected with the side surface of the support plate 600, so as to avoid affecting the reset operation of the auxiliary function assembly 610.

[0092] In the utility model, the bottom of the limiting pin 613 is a spherical head 6133 protruding in arc shape, the top of the first connecting piece 611 is provided with a downward recessed clamping groove 6111, and when the limiting pin 613 is located at the initial position, the spherical head 6133 is recessed in the clamping groove 6111, so as to realize the braking and limiting effect of the auxiliary function assembly 610 on the support plate 600.

[0093] Specifically, the limit pin 613 passes through the compression spring 614 and the through hole 6121 on the second connecting member 612 in sequence, and then passes through the second connecting member 612. A retaining spring 615 is provided on the side wall of the limit pin 613 near the lower end. The limit pin 613 has a braking position and a release position relative to the second connecting member 612: in the initial state, the limit pin 613 is in the braking position, at which time the compression spring 614 is in the compression limit position, and a gap is provided between the retaining spring 615 and the lower end surface of the second connecting member 612; in the post-movement state, the limit pin 613 is in the release position, at which time the limit pin 613 is displaced upward relative to the braking position under the action of the compression spring 614 until the retaining spring 615 abuts against the lower end surface of the second connecting member 612, and the retaining spring 615 limits the movement position of the limit pin 613.

[0094] Since the compression spring 614 is in a compressed state when the limiting pin 613 is in the initial state, in order to ensure that the limiting pin 613 can maintain the initial state, the second connecting member 612 of the present invention is further provided with a bolt-type positioning bead 617. The bolt-type positioning bead 617 passes through the second connecting member 612 and engages with the limiting pin 613, so that the limiting pin 613 can maintain the initial state and is limitedly connected to the first connecting member 611 in the initial position. When the bolt-type positioning bead 617 is separated from the limiting pin 613, the limiting pin 613 moves upward under the action of the compression spring 614. Preferably, the limiting pin 613 is provided with an inwardly concave second limiting groove 6132. The front end of the bolt-type positioning bead 617 passes through the second limiting hole 6123 on the second connecting member 612 and engages with the second limiting groove 6132.

[0095] The bolt-type positioning bead 617 in the present invention includes a positioning bolt 6171, the front end of which is provided with a groove, a positioning spring 6172 and a positioning bead 6174 being disposed within the groove, the positioning spring 6172 being in a compressed state so that the front end of the positioning bead 6174 protrudes from the groove and engages with the limit pin 613. Preferably, the front end of the groove is provided with an inner screw hole, the inner diameter of the inner screw hole being smaller than the diameter of the positioning bead 6174, so as to prevent the positioning bead 6174 from falling out of the groove. In addition, a positioning pad 6173 (the front end of the positioning pad 6173 may be provided with an arc-shaped receiving groove) may be further provided within the groove, the positioning pad 6173 being located between the positioning spring 6172 and the positioning bead 6174, and isolating the positioning spring 6172 from the positioning bead 6174 by the positioning pad 6173. This ensures a balance of elastic forces between the positioning bead 6174 and the positioning spring 6172, and prevents the positioning bead 6174 from shifting within the entire groove.

[0096] The utility model discloses, the first limiting hole 6122 is equipped with on the second connecting piece 612, the first limiting slot 6131 of recessed is equipped with on the limiting pin 613, and the first limiting slot 6131 is connected with the first limiting hole 6122 of the second connecting piece 612 after the tight screw 616 passes through, can avoid the disengagement of limiting pin 613 when the impact intensity is greater than the force of bolt type positioning bead 617 to limiting pin 613 in the carrying, installation shock insulation device process, make shock insulation device have more reliable stability.

[0097] Preferably, the tight screw 616 is screwed with the first limiting hole 6122 on the second connecting piece 612, when the fastening effect of the tight screw 616 to the limiting pin 613 is needed, the tight screw 616 is screwed forward to make it connected with the limiting pin 613, when the shock insulation device is used normally, the tight screw 616 is screwed backward, and the front end of the tight screw 616 is separated from the limiting pin 613, so that the operation is more convenient.

[0098] As shown in the drawings, Figure 12 When the bolt type positioning bead 617 limits the position of the limiting pin 613 in the initial state, the Y-axis slide rail assembly, the supporting plate 600 and the upper equipment do not displace when the whole shock insulation device meets accidental touch or small earthquake, guaranteeing the safety of the upper equipment. When a large earthquake occurs, the earthquake energy causes the upper equipment to shake and exceed the limiting effect of the bolt type positioning bead 617 to the limiting pin 613, and the limiting pin 613 moves upward under the action of the compression spring 614, at this time, the limiting pin 613 is separated from the first connecting piece 611, and the shock insulation device can consume the acceleration of the seismic wave, so that the shock insulation effect is realized. After the earthquake, the second connecting piece 612 returns to the position aligned with the first connecting piece 611, at this time, the limiting pin 613 is in a released state, so that the manual / other automatic structure (such as an electromagnet) presses the limiting pin 613, and the braking connection state between the first connecting piece 611 and the second connecting piece 612 is realized.

[0099] As shown in the drawings, Figures 18 to 23 In the utility model, the upper equipment is displaced under the influence of the seismic wave, which can not only move left and right in the X direction, but also move forward and backward in the Y direction, and can also move in the circumferential direction under the action of the XY direction force. The upper equipment is set as a device with uniform mass, and the center of gravity is located at the physical center, the center of gravity of the upper equipment is located at the intermediate position of the first Y-axis slide rail assembly 200 and the second Y-axis slide rail assembly 300, and is located at the central position of the X-axis slide rail assembly 100.

[0100] When the upper device is subjected to an X-direction force that exceeds the braking force of the auxiliary function assembly 610, the upper device, together with the support plate 600, the first Y-axis slide rail assembly 200, the second Y-axis slide rail assembly 300, the two first slider assemblies 400, and the two second slider assemblies 500, all displace in the X-direction. Since the first Y-axis slide rail assembly 200 and the second Y-axis slide rail assembly 300 move synchronously with the upper device, after the upper device is displaced, its center of gravity remains in the middle position between the first Y-axis slide rail assembly 200 and the second Y-axis slide rail assembly 300, and this position remains within the support range of the X-axis slide rail assembly 100. Therefore, the support position of the seismic isolation device for the upper device remains within its support range, will not overturn, and has higher structural stability.

[0101] When the upper device is subjected to a force in the Y direction and the force exceeds the braking force of the auxiliary function component 610, the upper device together with the support plate 600, the first Y-axis slide rail assembly 200, the second Y-axis slide rail assembly 300, the two first slider assemblies 400, and the two second slider assemblies 500 are all displaced in the Y direction. Since the two first slider assemblies 400 and the two second slider assemblies 500 will move synchronously with the upper device, after the upper device is displaced, its center of gravity position is still on the central axis of the first Y-axis slide rail assembly 200 and the second Y-axis slide rail assembly 300, and this position is still on the central axis of the X-axis slide rail assembly 100; since the center of gravity position of the upper device deviates from the support center of the X-axis slide rail assembly 100, a torque force with a force arm will be generated on the support center position of the two first slider assemblies 400 and the two second slider assemblies 500, and since the two first slider assemblies 400 and the two second slider assemblies 500 are separated from each other and set separately, therefore (with Figure 23 For example, the two second slider assemblies 500 located on the same straight line are subjected to compression, and the two first slider assemblies 400 located on the same straight line are subjected to tension. The slider system composed of the four slider assemblies has high pressure-bearing and load-bearing capacity, the seismic isolation device has high pressure resistance and torque resistance, and the overall load-bearing capacity of the seismic isolation device is high.

[0102] In terms of the overall aspect, the utility model utilizes the low friction coefficient and other characteristics of the linear slide rail to achieve the function of isolating the conduction of seismic forces, and utilizes intersecting linear slide rails to achieve the function of horizontal movement in any direction. In addition, the reset part is used to drive the upper equipment to reset and achieve the damping effect.

[0103] In terms of details, the utility model utilizes four support points that are offset and separated from each other to achieve stable support for the upper equipment and provide strong anti-bending, anti-torsion and anti-overturning capabilities. At the same time, the utility model can also provide a bearing capacity far exceeding that of existing seismic isolation devices; the utility model can make the device structure more compact and reduce the difficulty of system design and installation through the design of the reset parts and their connection relationships; the utility model can provide more stable support for the upper equipment and offset the effects of seismic forces through the structural design of the slide rail; the utility model can make the scraper more sensitive to acceleration through the material selection, so that the greater the acceleration, the greater the resistance; the utility model can reduce the installation difficulty of each slider and reduce the ability requirements of the installation workers through the structural design of the slider assembly.

[0104] This utility model is based on the established vibration isolation device model and the finite element model of the upper equipment, and uses the finite element analysis model SAP2000 software for simulation. Taking motion acceleration as the primary analysis quantity, the vibration isolation efficiency under different seismic waves is obtained, as shown in the following table:

[0105]

[0106] It can be seen from the above table that the vibration isolation device of the present invention has an excellent consumption effect on the acceleration of seismic waves and can provide vibration isolation protection for the upper equipment.

[0107] Based on the structure of the above-mentioned seismic isolation device, the utility model also provides a design and evaluation method for a seismic isolation device. It should be pointed out that the design and evaluation method is only a design guide and is not a precise calculation process. Certain parameters are ignored or their results are rounded to integers (such as the self-weight of the seismic isolation device, etc.) during the design guidance process.

[0108] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.

[0109] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the present utility model patent is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
