Description

Technical Field

[0001] The utility model relates to the field of bridge equipment, in particular to a swivel-adjustable earthquake-resistant spherical bearing structure. Background Art

[0002] The swivel adjustable seismic spherical bearing structure can be traced back to the continuous improvement of earthquake safety and continuous innovation of construction engineering technology. The emergence of the swivel adjustable seismic spherical bearing structure not only improves the safety of buildings in earthquakes, but also reduces the cost of maintenance and reconstruction, providing people with a safer and more stable environment for living and working. With the continuous advancement of science and technology and the continuous improvement of engineering technology, this bearing structure will continue to play an important role in the field of earthquake disaster prevention and contribute to the sustainable development of construction projects.

[0003] The existing seismic spherical bearing is an innovative structure for improving the seismic performance of buildings. Its main structure includes a sphere, an upper and lower base and a supporting structure. The sphere is made of high-strength metal material, and a supporting and rotating mechanism is arranged inside it, so that the sphere can rotate freely in the horizontal and vertical directions. The upper and lower bases are respectively fixed on the structure and foundation of the building to support and fix the sphere. When an earthquake occurs, the building structure is affected by the seismic force and will undergo vertical displacement and vibration. At this time, the spherical bearing can flexibly rotate and adjust so that the building structure can follow the changes in the seismic waves and undergo corresponding displacement, thereby reducing the impact and damage caused by the earthquake. The design of the spherical bearing enables it to absorb seismic energy and reduce the impact of the earthquake on the building structure.

[0004] However, the fixed height of the existing seismic spherical bearings limits the ability to adjust and repair after an earthquake. When the building structure is unstable or damaged due to an earthquake, it is difficult to adjust and repair the fixed height bearings in a timely manner, which may lead to further damage or safety hazards. Therefore, a swivel adjustable seismic spherical bearing structure is proposed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3, the utility model provides an embodiment: a swivel adjustable earthquake-resistant spherical bearing structure, including a lower support body 1, the outer wall of the lower support body 1 is slidably connected to an upper support body 2, the outer wall of the upper support body 2 is provided with a socket 3, the lower support body 1 is fixedly connected to a motor 4, the output end of the motor 4 is fixedly connected to a gear 1 5, the lower support body 1 is rotatably connected to a gear 2 7, the gear 2 7 is meshed with the gear 1 5, the bottoms of the gear 1 5 and the gear 2 7 are both fixedly connected to a screw rod 6, the outer wall of the screw rod 6 is threadedly connected to a slider 8, the outer walls of the slider 8 are rotatably connected to a transmission rod 9, the transmission rod 9 is rotatably connected to a wedge block 10, one side of the outer wall of the wedge block 10 is slidably connected to a wedge block 2 11, the top of the wedge block 2 11 is fixedly connected to the upper support body 2, and a sliding component is provided at the bottom of the lower support body 1;

[0025] Specifically, when using the swivel adjustable earthquake-resistant spherical support structure, when the height needs to be adjusted, first power is supplied to the motor 4 through the socket 3, and then the motor 4 is started, and then the motor 4 drives the gear 1 5 and the gear 2 7 to rotate, thereby rotating the screw 6, and then the screw 6 drives the slider 8 to move downward, and then the slider 8 drives the transmission rod 9 to move, and then the wedge block 1 10 squeezes the wedge block 2 11, so that the upper support body 2 is raised, and the height adjustment of the structure can be completed. When the support height is fixed, when the building structure is greatly deformed in an earthquake, it may be difficult to restore the original state. This may require more complicated maintenance and reinforcement work, increasing maintenance costs and time. This structure makes it easier to maintain and repair the building structure after it is deformed by an earthquake or other external forces. By adjusting the height, the balance and stability of the structure can be restored in time, reducing further damage and repair costs.

[0026] Reference Figure 1 - Figure 3 The sliding assembly includes a protrusion 12 and polytetrafluoroethylene 13, the polytetrafluoroethylene 13 is slidably connected to the outer wall of the protrusion 12, and the top of the protrusion 12 is fixedly connected to the inside of the lower support body 1;

[0027] Specifically, when using the swivel adjustable earthquake-resistant spherical bearing structure, when an earthquake occurs, the convex body 12 at the bottom of the lower support body 1 will slide on the polytetrafluoroethylene 13, which can reduce some of the damage to the building structure caused by the vibration. The reason why polytetrafluoroethylene 13 is used in this structure is that polytetrafluoroethylene 13 is a material commonly used to reduce friction, has good wear resistance and a low friction coefficient, and is commonly used to manufacture sliding parts, seals, and lubricating materials, etc., and can resist the friction of the spherical bearing to a certain extent.

[0028] Reference Figure 2 - Figure 4The outer wall of the polytetrafluoroethylene 13 is fixedly connected to a base 14, the lower support body 1 is fixedly connected to a connecting rod 16 in a ring array, the outer wall of the base 14 is fixedly connected to a connecting plate 22, the connecting plate 22 is threadedly connected to a bolt 15, the outer wall of the connecting rod 16 is fixedly connected to a sleeve 17, the outer wall of the sleeve 17 is fixedly connected to a rotating column 18, the outer wall of the base 14 is fixedly connected to a fixed block 21, one side of the outer wall of the fixed block 21 is fixedly connected to a damper 20, the output end of the damper 20 is fixedly connected to a connecting block 19, and one side of the outer wall of the connecting block 19 is rotatably connected to the outer wall of the rotating column 18;

[0029] Specifically, when using the swivel adjustable seismic spherical bearing structure, when an earthquake occurs, the vibration generated by the earthquake will be partially offset by the spherical structure. When the lower support body 1 vibrates up and down, the force is transmitted to the connecting rod 16 through the lower support body 1, and then transmitted to the damper 20 by the connecting rod 16. Finally, the damper 20 absorbs and disperses the energy. This structure can effectively absorb and disperse seismic energy and reduce the impact of earthquakes on building structures. This energy absorption and dispersion can reduce the amplitude and acceleration of the structure, reduce the destruction and damage caused by earthquakes, and improve the seismic resistance of the building.

[0030] Working principle: When using the swivel adjustable anti-seismic spherical bearing structure, firstly, according to the required height, energize the motor 4 through the socket 3, and then start the motor 4, the motor 4 drives the gear 1 5 to rotate, and then the gear 1 5 drives the gear 2 7 to rotate, and then the gear 1 5 and the gear 2 7 respectively drive the bottom screw 6 to rotate, and the rotation of the screw 6 will drive the slider 8 to move, thereby driving the wedge block 1 10 to squeeze the wedge block 2 11 through the transmission rod 9, because the inclined surfaces of the wedge block 10 and the wedge block 2 11 coincide, so the wedge block 10 squeezes the wedge When the block 11 is moved, the wedge block 11 will be forced to move upward, so that the upper support body 2 will rise to adjust the height. When vibrated, the lower support body 1 will transfer the force to the convex body 12, and then the convex body 12 will slide on the top of the base 14. At this time, when one side of the lower support body 1 is displaced downward, it will drive the connecting rod 16 to move, and then the connecting rod 16 will drive the sleeve 17 to move, and then the sleeve 17 will drive the connecting block 19 to move, and then the damper 20 will absorb and disperse the force on the connecting block 19, thereby absorbing and dispersing the vibration force to improve the stability and controllability of the structure.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
