Abstract
Description
Technical Field
[0001] The utility model relates to the field of friction pendulum bearings, in particular to a stainless steel plate inlaid spherical friction pendulum bearing. Background Art
[0002] Friction pendulum bearings are common structural control devices in building seismic isolation products. They are often used to bear the bridge's own gravity and external loads, and fix the bridge on the bearing through friction. Friction pendulum bearings can reduce the vibration and vibration of the bridge and improve the stability and safety of the bridge.
[0003] The existing friction pendulum bearing can fully guarantee the stability of the bridge by relying on the static friction between the upper deadweight and the bridge when the bridge experiences a small vibration. When the seismic force is large, the bearing slides according to a certain period, so that the seismic force on the upper structure of the bridge is no longer transmitted to the lower structure. Although the vibration of the bridge can be absorbed, there are still some shortcomings. When the pressure on the bridge is large, the movement amplitude of the cylinder will increase, which can easily cause the cylinder to detach. At the same time, although the setting of the arc can make the cylinder have a reset function, when the cylinder moves a large distance, it is easy to cause the cylinder to be unable to reset, which makes the friction pendulum bearing unusable. Therefore, a stainless steel plate inlaid spherical friction pendulum bearing is proposed to solve the above problems. Utility Model Content

[0028] 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.
[0029] Reference Figure 1 and Figure 2The utility model provides an embodiment: a stainless steel plate inlaid spherical friction pendulum bearing, comprising a mounting plate 1, a connecting plate 2 is fixedly connected to the top of the mounting plate 1, an arc steel plate 3 is arranged on the top of the connecting plate 2, the material of the arc steel plate 3 is stainless steel, and the use of stainless steel can make the arc steel plate 3 corrosion-resistant and improve the strength of the arc steel plate 3, a connecting plate 2 4 is installed on the top of the connecting plate 2, the arc steel plate 3 is arranged between the connecting plate 1 2 and the connecting plate 2 4, the middle part of the connecting plate 1 2 is slidably connected with a bolt, and the bolt and the connecting plate 2 4 are threadedly connected, and the arc steel plate 3 can be placed between the connecting plate 1 2 and the connecting plate 2 4 and the arc steel plate 3 can be inlaid between the connecting plate 1 2 and the connecting plate 2 4 by using the bolt, thereby improving the installation speed of the arc steel plate 3, and the arc steel plate 3 can be quickly removed when maintenance or replacement is required.
[0030] Reference Figure 1 and Figure 2 A support column 5 is provided on the top of the arc steel plate 3. The support column 5 can be limited by the connecting plate 2 4 to prevent the support column 5 from being disconnected from the arc steel plate 3 when moving, so that the support column 5 can be continuously used. Both ends of the support column 5 are fixedly connected with tetrafluoroethylene plates 17. The tetrafluoroethylene plates 17 can make the support column 5 slide between the two arc steel plates 3 after connection. A damping rod 7 is fixedly connected to the middle part of the connecting plate 2 4. The other end of the damping rod 7 is fixedly connected to a rubber pad 6, and the rubber pad 6 is in contact with the support column 5.
[0031] Reference Figure 1 and Figure 2 The rubber pad 6 and the damping rod 7 can prevent the support column 5 and the connecting plate 2 4 from directly colliding when the support column 5 moves a large position, thereby preventing the support column 5 from being damaged due to the collision. At the same time, when the support column 5 moves, the rubber pad 6 will be squeezed and the rubber pad 6 will compress the damping rod 7. When the rubber pad 6 is not squeezed by external force, the support column 5 can be rebounded with the rubber pad 6 under the action of the damping rod 7, thereby automatically resetting the support column 5, thereby avoiding the situation where the support column 5 cannot be reset due to excessive displacement.
[0032] Reference Figure 1 and Figure 2 A reinforcing assembly is fixedly connected to the middle of the connecting plate 2 4 , and the reinforcing assembly includes a reinforcing plate 8 , which is fixedly connected to the middle of the connecting plate 2 4 . The reinforcing plate 8 can improve the strength of the connecting plate 2 4 and reduce the vibration pressure borne by the connecting plate 2 4 .
[0033] Reference Figure 1 and Figure 3, a steel cone 10 is slidably connected to the middle part of the mounting plate 1, and a baffle 9 is fixedly connected to the top of the steel cone 10, the baffle 9 is in contact with the mounting plate 1, and the middle parts of the baffle 9 and the steel cone 10 are rotatably connected with a threaded rod 11, by placing the steel cone 10 in the middle part of the mounting plate 1, and using a tool to squeeze the baffle 9 to make the steel cone 10 enter the object that provides the support position of the mounting plate 1, and then the steel cone 10 can be initially limited, and at the same time, the mounting plate 1 can be prevented from moving translationally, the outer periphery of the threaded rod 11 is threadedly connected to a nut seat 12, and the outer side of the nut seat 12 is rotatably connected to a plurality of connecting blocks 13, and the other side of the connecting block 13 is rotatably connected to a movable block 14, the movable block 14 is slidably connected to the middle part of the steel cone 10, and the other side of the movable block 14 is fixedly connected to a steel cone 2 15, a through hole is provided in the middle part of the steel cone 10, and the steel cone 2 15 is slidably connected to the middle part of the through hole.
[0034] Reference Figure 3 When the threaded rod 11 rotates, the nut seat 12 can be driven to descend. When the nut seat 12 descends, the connecting block 13 can squeeze the movable block 14 so that the movable block 14 extends the steel cone 2 15 out of the middle part of the steel cone 10, thereby further restricting the steel cone 10, fixing the mounting plate 1, and the steel cone 10 cannot be separated from the connected object. When the nut seat 12 rotates in the opposite direction, the movable block 14 can retract the steel cone 2 15 into the steel cone 10, thereby taking out the steel cone 10, and at the same time, the arc steel plate 3 or the support column 5 can be conveniently replaced or repaired, and when the mounting plate 1 is installed and fixed, there is no need to open a hole with a thread on the connected object, thereby improving the assembly and disassembly speed of the mounting plate 1.
[0035] Reference Figure 1 and Figure 2 The top of the threaded rod 11 is fixedly connected with a connecting component, which includes a connecting seat 16. The connecting seat 16 is fixedly connected to the top of the threaded rod 11. An electric screwdriver can be directly used to drive the threaded rod 11 to rotate through the connecting seat 16, thereby reducing the labor required for rotating the threaded rod 11 and at the same time.
[0036] Working principle: When in use, when the support column 5 moves significantly, it can contact with the rubber pad 6, and then squeeze the rubber pad 6. At the same time, when the rubber pad 6 is squeezed, the damping rod 7 will be compressed. When the pressure of the rubber pad 6 disappears, the rubber pad 6 squeezes the support column 5 under the action of the damping rod 7, and then can cooperate with the support column 5 to reset. At the same time, under the action of the connecting plate 2 4, the support column 5 can be prevented from separating from the arc steel plate 3 when moving.
[0037] Among them, after the steel cone 10 is placed in the middle of the mounting plate 1, the baffle plate 9 is pressed by using a tool so that the baffle plate 9 drives the steel cone 10 to enter the object to which the mounting plate 1 needs to be fixed. At the same time, under the action of the connecting seat 16, the threaded rod 11 can be rotated by an electric screwdriver. When the threaded rod 11 rotates, the nut seat 12 drives the connecting block 13 to flip, and at the same time, the movable block 14 can be driven to push out the steel cone 2 15, so that the steel cone 10 can be limited and the mounting plate 1 can be fixed at the same time. The steel cone 2 15 can be put into the steel cone 10 by rotating the connecting seat 16 in the opposite direction, so that the mounting plate 1 can be quickly disassembled and the arc steel plate 3 or the supporting column 5 can be maintained or replaced.
[0038] 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.
