Problems solved by technology

[0008] In view of the above-mentioned prior art, the object of the present invention is how to provide a two-way shock-absorbing and isolating ball bearing, which aims to solve the problem that the existing shock-absorbing and isolating bearings can only reduce the kinetic energy in the horizontal direction, but cannot absorb or weaken the vertical kinetic energy. Kinetic energy in the vertical direction and technical problems that are not self-recoverable and cannot be repaired

Embodiment 1

[0027] combine figure 1 and figure 2 As shown, the present invention fixes the upper support plate 7 on the bridge and fixes the lower support plate 1 on the pier by pre-embedding the anchor bolt 8 and the sleeve 9 .

[0028] Under normal working conditions, or when the earthquake does not reach a certain intensity, under the restriction of the guide plate, the upper and lower bearing plates of the bearing will slide relative to each other along the principal displacement direction. At this time, the support takes place as follows: the shock-absorbing rubber plate 2 is compressed or unstressed according to the change of the vertical bearing capacity, reducing the hard impact between the support parts; the spherical crown liner 5 is opposite to the upper support plate 7 Doing pendulum motion, the shock-absorbing slide 6 is attached to the spherical crown liner, and sliding friction occurs with the upper support plate, absorbing the kinetic energy of the support, and dissipati...

Embodiment 2

[0031] How Bidirectional and Fixed Bearings Work Bidirectional and fixed bearings work similarly to unidirectional bearings. In normal working condition, when the upper and lower bearing plates of the bidirectional bearing are in normal working condition, the upper and lower bearing plates of the bidirectional bearing can slide relative to each other along the main displacement direction and the non-main displacement direction, that is, the displacement in the main displacement direction is relatively small. big.

Abstract

The invention discloses a damping and shock insulating bidirectional spherical support which comprises a lower support plate, an upper support plate, anchor bolts and sleeves, wherein a damping rubber plate, a spherical concave liner plate, a spherical surface sliding plate, a spherical crown liner plate and a damping sliding plate are further sequentially arranged from bottom to top between the lower support plate and the upper support plate; the damping sliding plate and the spherical surface sliding plate are respectively adhered to the upper and lower sides of the spherical crown liner plate; guide plates and shearing bolts are arranged at the left and right ends of both the upper support plate and the lower support plate; the guide plates are fixed on the upper support plate and the lower support plate through the shearing bolts. Due to adoption of the damping rubber plate on the lower support plate, the vertical kinetic energy of a bridge is converted into potential energy and heat energy of the bridge itself in earthquake, then the impact of components of the support is alleviated; as the guide plates are fixed on the upper support plate through the shearing bolts, after the earthquake, the support can be recovered by self; if the shearing bolts are cut off, the support can be recovered to a normal use state by only replacing the shearing bolts and resetting the guide plates.

Description

technical field [0001] The invention relates to the technical fields of bridges and construction engineering, in particular to a shock-absorbing and isolating two-way ball bearing with good shock-absorbing effect. Background technique [0002] Earthquakes are vibrations on the earth's surface caused by the sudden release of slowly accumulated energy inside the earth; strong ground vibrations will directly and indirectly cause the collapse and destruction of bridges and buildings, becoming disasters. [0003] Since the 20th century, a large number of scholars have devoted themselves to the scientific research of earthquakes. Until the 1950s, the "Earthquake Engineering Theory System" was basically established to understand the causes and mechanisms of earthquakes in a correct sense. After the 1970s, the theory of anti-seismic development developed rapidly, especially the technology of shock absorption and isolation was proposed, which played a revolutionary role in the anti-s...
