Description

Shock-absorbing support and shock-absorbing bridge device with switchable anti-seismic mode

technical field

The utility model relates to the technical field of bridge anti-seismic and bridge anti-seismic isolation, in particular to a shock-absorbing bearing and a shock-absorbing bridge device with a switchable anti-seismic mode.

Background technique

An earthquake is a phenomenon of propagating vibrations that occurs when a part of the earth's interior moves rapidly. When a major earthquake breaks out, it releases huge seismic energy, causing a lot of damage to the surface and man-made engineering, seriously threatening the safety of people's lives and property. The damage to bridges by earthquakes directly affects the smoothness of lifelines in the process of earthquake relief. Therefore, how to improve the seismic capacity of bridges and reduce the damage to bridges caused by earthquakes is a very important issue.

The nature and degree of damage to bridge structures are different due to different bridge structure forms, detailed structures, and ground motion characteristics of the site. The bridge bearing is an important connecting structure between the superstructure and the substructure of the bridge, and its main function is to transfer the load of the superstructure to the pier. The cost of bearings accounts for only a small proportion in the overall cost of the bridge structure, but its role in the bridge structure is very large. The support is a relatively weak link in the bridge structure. In the event of an earthquake, the damage of the support will have a huge impact on other parts of the bridge, making the degree of earthquake damage worse. Therefore, the performance of the bearing has a decisive effect on the overall performance of the bridge to a certain extent.

Existing anti-seismic bearings for bridge structures include lead-core rubber bearings, high-damping rubber bearings, anti-seismic basin bearings, friction pendulum bearings, and the like. These types of anti-seismic bearings still have some problems of insufficient anti-seismic capacity under the action of earthquake loads, such as: poor torsion resistance, insufficient limit capacity, and low impact resistance. Moreover, in order to improve the performance and reliability of the shock-absorbing and isolating bearings, most bearings need to be used in conjunction with other damper structures, making the manufacturing process complicated, requiring high material performance, and greatly increasing the cost of the entire system. From the perspective of environmental protection, the pollution of lead rubber bearings is relatively serious.

Compared with the prior art, the beneficial effects of the shock-absorbing bearing and the shock-absorbing bridge device provided by the utility model are as follows:

Under normal conditions, the shock-absorbing support of the switchable anti-seismic mode is a restraint system. At this time, the arc-shaped shock absorbing element is fixedly connected to the first support through the connecting element. One end of the arc-shaped shock absorber is connected with the first support through the connecting piece, and the other end of the arc-shaped shock absorber is connected with the second support. Both ends of the hydraulic assembly are respectively connected to the arc-shaped shock absorber and the second support, and the part of the hydraulic assembly connected to the arc-shaped shock absorber can also support the arc-shaped shock absorber. At this time, the connecting piece is used to bear the horizontal shear force, and its design bearing capacity can ensure that it will not be sheared under normal conditions, wind vibration, and small and medium-level earthquakes, but will be sheared under the action of a large earthquake. Therefore, under normal working conditions, the arc-shaped shock absorber maintains its structural stability under the joint action of the connecting piece and the hydraulic assembly. The first connection part and the second connection part are connected to each other, which can ensure that no horizontal displacement occurs between the second support and the third support. And in the case of strong winds, it can maintain the stability of the structure and absorb the energy generated by wind vibration. In the case of a large earthquake, because the arc-shaped shock-absorbing element is subjected to a large instantaneous impact force, the part connected to the arc-shaped shock-absorbing element and the first support is displaced, and the connecting element is cut off. The switchable anti-seismic mode The shock absorber is converted into a shock absorbing system. At this time, the connecting piece is cut off, and the first support and the arc shock absorbing piece can slide relative to each other. The hydraulic components can absorb the instantaneous impact energy generated when the joint breaks and the energy transferred to the bearing during the earthquake. After the end of the hydraulic assembly connected with the arc-shaped shock absorber is squeezed, the viscous damping medium in the hydraulic assembly flows and absorbs part of the load. Since the viscous damping medium cannot flow in a large amount in a short time, the hydraulic components cannot move in a short time, and then the entire structure is locked in a rigid state to enhance the strength of the system. Due to the relatively large torsional force generated during the earthquake, the second support and the third support rotate relative to each other. The second connection part on the third support and the first connection part on the second support can limit the rotation angle of the second support and the third support in the horizontal direction. After the earthquake disappears, the pressure on the end of the hydraulic assembly close to the first support decreases, and resets gradually. Therefore, the arc-shaped shock absorber returns to a relatively stable position to a certain extent, so as to maintain the basic function of the support. Due to the action of the first connecting part and the second connecting part, the displacement of the third support is small, and at the same time, it is subjected to the action of the reverse force, and gradually moves to the initial position. After the earthquake disappears, the shock-absorbing support with convertible anti-seismic mode can maintain its function of supporting the upper structure to a certain extent, and maintain the smooth flow of the lifeline for earthquake relief. The shock-absorbing bearing and the shock-absorbing bridge device provided by the utility model have the advantages of simple structure, comprehensive functions and stable performance, strong torsion resistance under earthquake action, multi-mode dissipation of earthquake energy, and high structural stability.

It should be noted that, in this embodiment, in order to connect the connecting portion 1212 to the first support 111 more stably, the first support 111 is also provided with a mounting groove 1111 that matches the connecting portion 1212 . The connecting portion 1212 can be partially accommodated in the mounting groove 1111 , and the sidewall of the mounting groove 1111 can limit the connecting portion 1212 .

Please refer to FIG. 3 , the abutting assembly 122 includes an abutting seat 1221 and an abutting member 1222, the abutting seat 1221 is connected to the end of the second support 112 close to the first support 111, and the abutting member 1222 is abutted against the abutting seat Between the other end of 1221 and the arc portion 1211.

Please refer to Fig. 4, the abutment seat 1221 includes a plurality of first connection seats 12211 and a plurality of second connection seats 12212 connected in sequence, the first connection seats 12211 are connected with the second support 112, the second connection seats 12212 are connected with the arc Shaped shock absorber 121 is connected. The resisting member 1222 is resisted between the end of the first connecting seat 12211 away from the second support 112 and the arc-shaped shock absorbing member 121 to play a certain buffering effect when the arc-shaped shock absorbing member 121 is stressed. Preferably, the resisting member 1222 is made of elastic material, such as rubber.

In this embodiment, the second support 112 is provided with a mounting groove 1122 connected with the first connecting seat 12211, and the shape and structure of the mounting groove 1122 is matched with the first connecting seat 12211 to make the first connecting seat 12211 more stable. ground mounted on the second support 112. Meanwhile, in this embodiment, the second connecting seat 12212 is engaged with the third connecting hole 123 .

Referring to Fig. 5, the hydraulic assembly 130 includes a piston rod 131, a piston cylinder 132 and an elastic member 133, the piston cylinder 132 is connected with the second support 112, and one end of the piston rod 131 is accommodated in the piston cylinder 132 and connected with the piston cylinder 132 , the other end of the piston cylinder 132 is connected to the arc-shaped shock absorber 121 , and the elastic member 133 is held between the end of the piston rod 131 away from the piston cylinder 132 and the piston cylinder 132 .

It can be understood that, after the end of the piston rod 131 close to the first support 111 is squeezed, the piston rod 131 is displaced relative to the piston cylinder 132, and the viscous damping medium in the piston cylinder 132 flows in the upper and lower chambers, absorbing the The load transmitted by the piston rod 131. The elastic member 133 located between the piston rod 131 and the piston cylinder 132 can absorb a part of energy, so as to prevent the hydraulic component 130 from malfunctioning after being subjected to an instantaneous impact force. Since the viscous damping medium cannot flow in a large amount in the upper and lower chambers in a short time, the piston rod 131 cannot move in a short time, and the whole structure is locked in a rigid state, thereby enhancing the strength of the system.

In this embodiment, one end of the piston rod 131 close to the first support 111 is embedded in the first support 111 to ensure that the piston rod 131 will not break away from the first support 111 during an earthquake.

In this embodiment, the connecting piece 140 is a shear bolt, and a rubber tube 141 is sleeved outside the shear bolt, so as to adapt to the thermal deformation of the arc-shaped shock absorbing piece 121 under normal working conditions. shift.

The end part of the piece 121 connected with the connecting piece 140.

It can be understood that, when the connecting member 140 is broken, the arc-shaped shock absorbing member 121 moves to both ends respectively, and the end of the arc-shaped shock absorbing member 121 moves toward the accommodating space 114 . The function of the accommodating space 114 is to accommodate the end of the arc-shaped shock absorbing member 121 connected with the connecting member 140 to prevent it from falling off. The rubber pad 115 provided in the accommodating space 114 can reduce the impact when the arc-shaped shock-absorbing member 121 moves toward the accommodating space 114, and at the same time facilitate the reset of the arc-shaped shock-absorbing member 121 after the earthquake passes.

Please refer to FIG. 1 , FIG. 6 and FIG. 7 . In this embodiment, the first connecting portion 1121 and the second connecting portion 1131 cooperate with each other to prevent the horizontal movement between the second support 112 and the third support 113 . relative motion in the direction.

In this embodiment, the first connecting part 1121 includes a card slot 11211 and a limiting groove 11212, and the second connecting part 1131 includes a protrusion 11311 matched with the card slot 11211 and a limiting protrusion matched with the limiting groove 11212 From 11312.

It should be noted that the height of the slot 11211 is greater than the height of the protrusion 11311, that is, there is a certain space between the protrusion 11311 and the bottom wall of the slot 11211, and this space can partially absorb the second support 112 or the third support. The displacement of the support 113 in the vertical direction prevents damage to the engaging groove 11211 and the protrusion 11311 , and improves their lifespan. Preferably, the shock-absorbing rubber block 116 is resisted between the protrusion 11311 and the bottom wall of the slot 11211 .

It should be noted that the width of the slot 11211 is also greater than the width of the protrusion 11311 , and the buffer rubber block 117 is abutted between the protrusion 11311 and the side wall of the slot 11211 . Under normal working conditions, the buffer rubber block 117 can limit displacement and ensure the stability of the structure. Under earthquake action, the buffer rubber block 117 can prevent excessive rotational displacement of the structure, and at the same time play a buffering role. After the earthquake disappears, the reverse force will be generated due to the extrusion of the rubber before, which will push the structure to gradually reset.

In this embodiment, the end of the second support 112 close to the third support 113 is also provided with a shock absorbing groove, and the end of the third support 113 close to the second support 112 is provided with a shock absorbing groove matched with the shock absorbing groove. Shock raised.

It can be understood that the connection between the raised portion 11311 and the third support 113 is perpendicular to the horizontal plane, so its ability to withstand horizontal shear force is relatively small, and it is easy to be cut short when the horizontal shear force is too large, limiting The cooperation between the position protrusion 11312 and the limit groove 11212 can limit the horizontal displacement. That is to say, the protrusion 11311 and the slot 11211 are mainly used to limit the rotation angle between the second support 112 and the third support 113, and the limiting protrusion 11312 and the limiting groove 11212 limit the rotation angle of the second support 112. The horizontal displacement between 112 and the third support 113, and the contact surface of the limiting protrusion 11312 and the limiting groove 11212 can dissipate energy through friction when the second support 112 and the third support 113 rotate relative to each other.

In this embodiment, the limiting protrusion 11312 is a convex sphere, and the limiting groove 11212 is a concave sphere matched therewith. That is to say, the connecting surface between the limiting protrusion 11312 and the limiting groove 11212 is a spherical surface. The contact area of the spherical surface is larger, so that when the second support 112 and the third support 113 rotate relative to each other, the frictional energy dissipation capacity between the limiting protrusion 11312 and the limiting groove 11212 can be enhanced.

Moreover, in this embodiment, a friction pad 150 is also provided between the second support 112 and the third support 113 to increase the coefficient of friction between the second support 112 and the third support 113, so as to Prevent the second bearing 112 and the third bearing 113 from being worn due to mutual sliding.

The working principle and beneficial effects of the shock-absorbing support 100 with a switchable anti-seismic mode provided in this embodiment: under normal circumstances, the shock-absorbing support 100 with a switchable anti-seismic mode is a restraint system. One end of the arc-shaped shock absorber 121 is connected to the first support 111 through a connecting member 140 , and the other end of the arc-shaped shock absorber 121 is connected to the second support 112 . Both ends of the hydraulic assembly 130 are respectively connected to the arc-shaped shock absorber 121 and the second support 112, and the part of the hydraulic assembly 130 connected to the arc-shaped shock absorber 121 can also support the arc-shaped shock absorber 121 . At this time, the connecting piece 140 is used to withstand horizontal shear force, and its design bearing capacity can ensure that it will not be sheared under normal conditions, wind vibration and small and medium-level earthquakes, but will be sheared under the action of a large earthquake. Therefore, under normal working conditions, the arc-shaped shock absorbing member 121 maintains its structural stability under the joint action of the connecting member 140 and the hydraulic assembly 130 . The first connecting portion 1121 and the second connecting portion 1131 cooperate with each other to ensure that no horizontal displacement occurs between the second support 112 and the third support 113 . And in the case of strong winds, it can maintain the stability of the structure and absorb the energy generated by wind vibration.

In the case of a large earthquake, because the arc-shaped shock-absorbing member 121 is subjected to a large instantaneous impact force, the part connected to the arc-shaped shock-absorbing member 121 and the first support 111 is displaced, and the connecting member 140 is sheared, which can The shock-absorbing support 100 that switches the anti-seismic mode is converted into a shock-absorbing system. The hydraulic assembly 130 can absorb the instantaneous impact energy generated when the connecting member 140 breaks and the energy transferred to the support during an earthquake. After the end of the hydraulic assembly 130 connected to the arc-shaped shock absorber 121 is squeezed, the viscous damping medium in the hydraulic assembly 130 flows and absorbs part of the load. Since the viscous damping medium cannot flow in a large amount in a short time, the hydraulic component 130 cannot move in a short time, and the entire structure is locked in a rigid state to enhance the strength of the system.

Due to the large torsional force generated during the earthquake, the second support 112 and the third support 113 are relatively rotated. The second connecting portion 1131 on the third support 113 and the first connecting portion 1121 on the second support 112 can limit the rotation angle of the second support 112 and the third support 113 in the horizontal direction. After the earthquake disappears, the pressure on the end of the hydraulic component 130 close to the first support 111 is reduced, and resets gradually. Therefore, the arc-shaped shock absorber 121 returns to a relatively stable position to maintain the basic function of the support. Due to the action of the first connecting portion 1121 and the second connecting portion 1131 , the third support 113 has a small displacement, and at the same time, it is acted by a reverse force and gradually moves to the initial position. After the earthquake disappears, the shock-absorbing support 100 that can switch the anti-seismic mode can maintain its function of supporting the upper structure to a certain extent, and maintain the unimpeded lifeline of anti-seismic disaster relief.
