Description

Sliding isolation device

The invention relates to a sliding isolation device; in particular to a device for preventing vibration or vibration of a general building structure and a shock absorber for mechanical engineering components, which can be supported by means of suspension or suspended. The weight of the structure can simultaneously isolate the introduction of vibration energy, prevent the structure from being damaged, and achieve the effect of protecting the structure.

As shown in Figure 1, the conventional friction single pendulum isolation support (10), the friction single pendulum isolation support (10) uses the spherical sliding method to achieve the effect of isolation vibration, but the mechanism is the way of contact rather than the link The method is assembled, so it must be fixed by temporary fixing device, and can be removed after the installation is completed to avoid the parts from falling off, and the stability and safety of the mechanism are not good.

When the friction single pendulum isolation bearing (10) is subjected to vertical vibration, the component is prone to tripping. Once the part is detached, the function of the isolation can not be exerted, and the height of the basic support is uneven. Tilting causes damage and collapse, but it is more dangerous than non-isolated buildings, greatly reducing the practicality and safety of the isolation support.

In addition, if the vibration isolation structure of the friction single pendulum isolation bearing (10) is subjected to a large lateral force, if the tension-free device is subjected to the tensile force, the isolation structure is liable to cause the risk of dumping and overturning.

The isolation device shown in Fig. 2 uses the action of the slider or the roller on the track on the plate to achieve the effect of vibration isolation.

When the vibration isolation device of the circular arc track is operated by sliding mode or rolling mode, a single arc single contact method is used, that is, when the vehicle is stationary, the contact point is located at the lowest point of the arc, which is a stable position, but in the arc At the lowest point, the reaction force is vertical, and there is no horizontal component. Especially when using the rolling method, it may be activated when it is subjected to a slight horizontal force at rest. The isolation structure for the building structure or the placed items will be used. Troubles, such as building structures that may be shaken when subjected to wind, may cause dizziness to residents.

The invention is to make the contact position of the two points on the single track on the seismic isolation device, and the horizontal component of the reaction force of the gravity of the two contact positions can reach equilibrium, and the better binding force for the equilibrium position can be returned quickly and accurately. The positioning and the load can be dispersed to two places without being concentrated in one place, so that stress concentration is more likely to occur.

In the sliding isolation device (20) shown in Fig. 3, the movable member (50) is a slide-operated slider; the two ends of the connector (60) are hingedly coupled to the movable member (50); (40) articulating the center of the connector (60); the track base (30) is provided with a circular arc track (31); and the two sets of movable members (50) are hingedly coupled to the connector (60) At the end portion, the movable member (50) is rotatable relative to the connector (60); the center of the connector (60) is hingedly coupled to the hinge base (40), and the connector (60) is relative to the hinge base The seat (40) swings; two sets of movable members (50) are disposed on the same circular arc track (31) of the track base (30), and a single is generated between the hinge base (40) and the track base (30). When moving horizontally in parallel, the connector (60) will swing relative to the hinge base (40) so that the two sets of movable members (50) on the same circular arc track (31) of the track base (30) can At the same time produce scrolling, or sliding.

In the sliding isolation device (20) shown in Fig. 4, the movable element (50) is a rolling element that is actuated in a rolling manner.

Figure 5 is a schematic view showing a preferred application embodiment of the sliding isolation device (20) disposed at the bottom of the equipment machine (80) or display cabinet (81).

Figure 6 is a schematic view showing a preferred application embodiment of the sliding isolation device (20) disposed at the bottom of the structure (82). A mass (83) is mounted on the sliding isolation device (20) to form a mass damper. The mass damper is disposed on the top of the structure (82) or in the floor, and is swung by the mass (83). The recovery force counteracts the effects of vibration, and has the effect of buffering horizontal vibration to reduce amplitude.
