Background technique

Therefore, it can only adapt to the temperature deformation and concrete shrinkage and creep, as well as the low-speed impact load such as the service brake, and can not play the shock absorption under the large earthquake load. . Viscous dampers have powerful energy dissipation, but are limited to high-speed and large-displacement motions, such as strong winds and seismic loads. However, in low-speed and small-displacement motions, the output force is small, and the energy consumption of the viscous damper cannot be exerted. Strong advantages, such as weak winds, driving loads. In the prior art, the anti-seismic device which has the function of locking and damping energy consumption has too large locking displacement, thereby causing the sensitivity of the device to decrease, and the damping function is easily affected, and the damping performance is deviated.

When the locking speed is exceeded, it is always closed, ensuring that the fluid will not pass through the elongated locking hole and affect the damping performance of the device. The damping valve is closed at low speed and low pressure, which has no influence on the locking performance of the device. When it is opened under high speed and high pressure, the fluid passes through the precisely designed damping hole to produce specific damping performance. Therefore, the problem that the sensitivity of the device is reduced due to excessive locking displacement of the anti-vibration device which has the function of locking and damping energy consumption in the prior art, and the damping function is easily affected to cause deviation of the damping performance. It can be used on the continuous beam bridge to replace the traditional speed locker, which solves the problem that the output force of the traditional speed locker is infinitely increased when encountering a large earthquake load, resulting in the destruction of the structure or itself; floating in the cable-stayed bridge, suspension bridge, etc. Used on semi-floating system bridges, it can replace traditional viscous dampers, and solve the traditional viscous damper with almost no resistance under low speed loads such as service braking and weak wind.

Fig. 2 schematically shows the structure of a lock valve 7 of an embodiment of the present invention. As shown in FIG. 2, the lock valve 7 according to the embodiment of the present invention, in a preferred embodiment, includes a lock valve body 71, a lock valve body 72, a first elastic member 73, and a first stopper member 74. The lock valve body 71 is provided with a locking hole 75 disposed in the axial direction, and the lock valve body 72 is provided with a plurality of first flow guiding holes 76 that can communicate with the locking hole 75.

Specifically, as shown in Figures 3 and 4a, in a preferred embodiment, the orifices 87 are configured as elongated straight holes.
