Description

The present invention relates to an object support device that supports an object. In particular, the present invention relates to an object support device focusing on a seismic isolation function against vibration in the vertical direction.

As a horizontal object support device (for example, a seismic isolation table), several configurations have been conventionally devised. A horizontal seismic isolation table can be realized relatively easily. Since the weight of the object supported by the seismic isolation table is supported by the XY table, bearings, etc., the horizontal spring constant can be set relatively small to respond to horizontal acceleration vibration during an earthquake. For example, a mechanism such as a bearing can support a load in the vertical direction, suppress a resistance force against vibration in the horizontal direction, and effectively exert a seismic isolation effect.

On the other hand, an object support device for vibration in the vertical direction is required to have a simple configuration and can be realized at low cost.

Waves with various periods overlap with the waves of an earthquake, and among them, the wave component with a period of about 0.5 to 1.0 seconds is predominant. By making the natural period of the object support device in the vertical direction longer than 1 second, it is possible to avoid resonance of the object support device with respect to seismic waves and increase the seismic isolation effect. The seismic isolation effect increases as the vertical natural period of the object support device increases to 1 second, 2 seconds, 3 seconds, and 5 seconds. It is preferably at least about 2 seconds.

In order to make the vertical natural period of the object support device about 2 seconds, it is necessary to soften the spring in the vertical direction. Here, in order to set the natural period of the object support device in the vertical direction to about 2 seconds, if the spring constant is constant, a static deflection of about 1 m is required regardless of the mass of the object. I know. When an object is gently placed on a seismic isolation device in a no-load state, it sinks about 1 m and balances, and vibrates up and down around this static balance position to exert a seismic isolation effect. The height of the object support device is about 1 m to several tens of cm. If the natural period of the seismic isolation device in the vertical direction is set to 3 seconds and 5 seconds, the static deflection becomes even larger.

In particular, as the object support device for vibration in the vertical direction, a seismic isolation device having a non-linear spring characteristic having extremely small static deflection for a certain load and a soft spring constant when the load exceeds a certain value is preferable.
For example, when an object is placed on a table, it flexes statically up to one position and then statically suspends at that static suspension position. When an earthquake occurs, it vibrates up and down around the static suspension position.

The applicant of the present application and others are installed between a table on which an object is placed and moves up and down with respect to the base, and a spring force in the vertical direction according to the up and down movement of the table. A connecting member having a horizontally movable portion that connects the table and the base and moves along the horizontal direction with the vertical movement of the table, and the horizontally movable portion of the connecting member. A horizontal spring member that is engaged with a portion and generates a spring force in the horizontal direction according to the movement of the horizontally movable portion, and the connecting member is provided with a distance between the connecting members that changes with the vertical movement of the table. A pair of link members each having the horizontally movable portion are provided, one end of each of the pair of link members is rotatably engaged with the table, and both ends of the horizontal spring member are rotatably engaged with the table. A seismic isolation device, characterized in that it is connected to each of the horizontally movable parts, has been devised.
In the above invention, since the pair of link members have a horizontally movable portion, it is necessary to further provide a mechanism for suppressing the horizontal relative movement of the table with respect to the base.
The market wants to make it easier to suppress horizontal movement while maintaining the seismic isolation function by adding a simpler structure to the object support device devised by the applicant of the present application.

If the object support device according to the above-described embodiment is used, the following effects are exhibited.
An upward spring force is generated on the table 100 based on the base 200, and the pair of left and right guide blocks 310Br and 310Bl separated by the pair of left and right guide mechanisms 310 along the specific horizontal axis x are the other of the table 100 or the base 200.

The support link 332 is allowed to move up and down when the link 331r and 331l move up and down, and the table support mechanism can stably exert the desired seismic isolation function.
Further, when the pair of left and right first orbits g1 transitions along the direction away from each other along the specific horizontal axis x, the pair of left and right first orbits g1 are arranged so as to extend in one direction in the vertical direction as the transition occurs. By selecting the degree of bias in one of the vertical directions, the support characteristics of the table support mechanism can be selected according to the purpose, and the degree of freedom in design is increased.
Further, since the second orbit g2 is a linear orbit extending in the vertical direction, the other end of the support link 332 moves up and down in a straight line along the second orbit g2, and the main link member is moved. The left-right movement of the table can be stably suppressed through this.
Further, the support rotation center 332Cu is located on the main link virtual line which is a virtual line connecting the one rotation center 331Cu and the other rotation center 331Cd.
The distance between the one-side rotation center 331Cu and one support rotation center 332Cu, the distance between one support rotation center 332Cu and the other rotation center and 331Cd, and the distance between one support rotation center 332Cu and the other support rotation center 332Cd are equal to each other. Therefore, the main link 331 and the support link 332 can be stably tilted while moving, and the left-right movement of the table 100 can be stably suppressed via the main link 331.
Further, since the center of rotation of each of the pair of left and right links is separated by a predetermined separation distance H1 when viewed horizontally so that the pair of left and right main links 331r and 331l are divided into left and right, the degree of freedom in design is increased.
Further, since the pair of left and right main links 331r and 331l are viewed horizontally so as to be divided into left and right, the pair of left and right main links 331r and 331l intersect each other between one rotation center 331Cu and the other rotation center 331Cd. , Increases design freedom.
Further, when viewed horizontally so that the pair of left and right main links 331r and 331l are divided into left and right, the pair of left and right main links 331r and 331l intersect between each one rotation center 331Cu and the other rotation center 331Cd and are connected at an intersection. Because it is done, the degree of freedom in design increases.
Further, the pair of left and right one-sided guide mechanisms 312Rr and 312Rl move the pair of left and right one-sided guide blocks 312Brr and 312Bl separated along the specific horizontal axis x along the third orbit g3 with respect to the other of the table 100 or the base 200. It guides freely, and one end of the pair of left and right main links 331 is rotatably fixed to the pair of left and right guide blocks 312Br and 312Bl, and the other end is rotatably fixed to the pair of left and right guide blocks 311Br and 311Bl. It is fixed and a spring force is applied to the pair of left and right main links 331 in a direction approaching each other, one end of the support link 332 is rotatably fixed to at least one main link 331, and the other end is rotatably fixed to the table 100. Alternatively, it is rotatably fixed to the other of the base 200, while one end of the support link 333 is rotatably fixed to the other of the table 100 or the base 200, and the other end is rotated to at least one main link. Since it is fixed freely, the support link 332 and the support link 333 can suppress the left and right movement of the table 100 via the main link 331, and the table support mechanism can be selected by selecting the specifications of the link and the spring. The support characteristics can be selected according to the purpose, and the desired seismic isolation function can be exhibited.
Further, since the one-side support link 333 is movable along the fourth orbit g4, which is an orbit extending in the vertical direction with one end in one structure, and is rotatably supported around the one-side support rotation center 333Cu. The table support mechanism can stably exert the desired seismic isolation function by allowing the vertical movement of one end of one support link when the left and right main links move up and down with the vertical movement of the table 100.
Further, when the pair of left and right third orbits g3 transitions along the direction away from each other along the specific horizontal axis x, the pair of left and right third orbits g3 are arranged so as to extend in one direction in the vertical direction as the transition occurs. By selecting the degree of bias in one of the vertical directions, the support characteristics of the table support mechanism can be selected according to the purpose, and the degree of freedom in design is increased.
Further, since the fourth orbit g4 is a linear orbit extending in the vertical direction, one end of the support link 333 moves up and down in a straight line along the fourth orbit g4, and the main link 331 The left-right movement of the table can be stably suppressed through.
Further, since the vertical movement guidance mechanism (not shown) suppresses the relative rocking motion of the table 100 based on the base 200 and guides the table 100 so as to be movable in the vertical direction, the swinging motion of the table 100 is performed. Can be suppressed.
In addition, since N table support mechanisms 300 are arranged so as to surround the table when viewed from above to support each of the tables 100, the seismic isolation characteristics of the N table support mechanisms 300 are adjusted to a large extent. It is possible to create a large-scale object support device, increasing the degree of freedom in design.

The case where the horizontal movement guide mechanism 310 is provided on the base 200 has been described as an example, but the present invention is not limited to this. For example, the horizontal movement guidance mechanism 310 may be provided on the table 100.

For example, the lower structure of the table support structure may be the structure of the first to fourth embodiments.
