Description

Technical Field

[0001] The utility model belongs to the technical field of seismic isolation bearings, and more specifically, particularly relates to a friction pendulum bearing based on seismic reduction and isolation of building silos. Background Art

[0002] At present, most of the research on bulk grain building silos is on the design of structural systems. The structural form most commonly used in grain storage environments and technologies is the reinforced concrete frame structure. Therefore, the research on building silos mainly focuses on the seismic performance of frame structures, and less research is involved in seismic isolation bearings suitable for building silos. Since friction pendulum bearings can offset part of the vibration or shock energy and have good seismic performance, they can be widely used in seismic reduction and isolation of building silos.

[0003] After retrieval, it is found that the existing technologies of friction pendulum bearings in engineering structures mainly have the following technical improvement directions:

[0004] 1. Anti-pulling: In the published utility model patent "A tensile friction pendulum bearing (202023307854.4)", through the connecting blocks provided and the arc-shaped sliding grooves on both sides of the longitudinal support plate and the arc-shaped sliding grooves on both sides of the transverse support plate, during an earthquake, the support plates are connected by the connecting blocks, and their longitudinal or transverse movement has a large horizontal displacement deformation ability. The sliding surface of the transverse support plate is made of special metal and high molecular wear-resistant materials, and at the same time has the effects of low friction coefficient and high damping. Its special arc-shaped sliding groove enables it to return to the equilibrium position relying on the gravity borne on it, with strong automatic reset ability and strong anti-pulling ability. In the published utility model patent "A tensile friction pendulum bearing (202222943859.9)", by setting a sealing plate, the anti-pulling performance is also improved. There is also the published utility model patent "An anti-pulling friction pendulum bearing (202223532873.6)", which also solves the anti-pulling problem. There are many improvement studies in this direction.

[0005] 2. Reduce friction: In the published utility model patent "A tensile friction pendulum bearing (202023307854.4)", a stainless steel plate or chrome-plated layer is provided on the bottom surface of the upper bearing plate and the top surface of the lower bearing plate, and a silicone grease storage pit is provided on the surface of the upper spherical slide plate and the lower spherical slide plate, and silicone grease is applied to reduce the sliding friction and wear between the upper and lower bearing plates and the damping block, thereby increasing the service life of the device and reducing the subsequent maintenance cost. In the published utility model patent "Friction-reducing and wear-resistant friction pendulum seismic isolation bearing (202023307854.4)", a wear-resistant and corrosion-resistant coating is provided on the lower surface of the upper bearing plate. When the upper bearing plate and the spherical crown plate move, the friction coefficient is small, the wear resistance is good, and the anti-corrosion effect is good. The wear-resistant and corrosion-resistant coating not only reduces the friction coefficient, but also prevents the upper bearing plate from corroding and rusting due to contact with humid air during use, thereby extending the overall service life of the bearing and reducing maintenance costs.

[0006] 3. Replacement of parts: The authorized invention patent "Replacement method of friction pendulum bearing and its shear limit pin (201710042257.7)", the authorized utility model patent "Removal structure of broken limit pin of friction pendulum bearing after earthquake (201620521596.4)", and the authorized utility model patent "Multi-stage energy-absorbing friction pendulum bearing with replaceable limit device (201720745278.0)" all solve the problem of how to replace the limit device (pin) of the friction pendulum bearing.

[0007] Based on the above research improvement direction, combined with the inventor's experience and summary, it is believed that in the friction pendulum bearing technology, it is important to use various technical means to protect the components and extend the life of the components. However, the bearing is subject to external force vibration all year round, and trying to protect the components is only a technical means to ensure the reliability of the bearing in a short period of time. In the long run, the technical means of replacing key components are the ultimate means to ensure the performance of the entire bearing. The inventor believes that the more important parts than replacing the above limit pins are the sliders and related components that are in a state of long-term stress wear, so this problem should be taken seriously and solutions should be sought to ensure that the structure of the building warehouse is not easily damaged by earthquakes for a long time.

[0021] The utility model at least has the following beneficial effects:

[0022] 1. In the utility model, since the building granary often needs to dump and empty grain, the building granary is easily impacted by the external force of grain and vibrates, and in the earthquake zone it is also affected by seismic waves. Therefore, installing a friction pendulum support at the bottom of the building granary can offset part of the energy, and through the continuous back-and-forth friction between the sliding assembly and the sliding groove, it can effectively weaken the damage of vibration or vibration to the building granary structure.

[0023] 2. In the present utility model, since the sliding assembly is often subject to wear, its effectiveness will decrease year by year in the long run.

Specifically, the sliding assembly includes a steel ball, a lower limit groove, a force ear, a threaded column, and a sliding cylinder. By rotating the force ear, the lower limit groove can be lowered as the threaded column is retracted into the sliding cylinder, so that the steel ball is disengaged from the upper limit groove, and the lifting structure bears the gravity of the building warehouse, so that the worn sliding assembly is taken out and replaced with a new sliding assembly, thereby completing the replacement of parts, thereby maintaining the good performance of the sliding assembly to improve the vibration and earthquake resistance of the building warehouse. In addition, the setting of the oil immersion tank and the oil immersion hole column allows lubricating oil to be introduced into them before replacement, making the rotation smoother, more labor-saving and more smooth.

[0024] 3. In the utility model, the driving device cooperates with the lifting mechanism, and the rotating driving device makes the threaded rod of the lifting mechanism rise from the lifting cylinder and press against the upper support, so as to bear the gravity of the building warehouse during the replacement of the sliding component, so that the replacement can be carried out smoothly. In addition, a force ring is fixed on the top of the threaded rod of the lifting mechanism, and it can cooperate with the annular groove on the bottom surface of the upper support main board to bear force, so that the gravity of the building warehouse can be dispersed to the three threaded rods, making the force more uniform, and preventing a single threaded rod from being bent or broken due to greater force.
