Description

Adjustable bridge seismic support

Technical Field

The utility model belongs to the technical field of bridge engineering, and in particular relates to an adjustable bridge earthquake-resistant support.

Background Art

In recent years, earthquakes and geological disasters have occurred frequently in my country. As a hub of transmission lines, bridges, once damaged in an earthquake, not only cause economic losses, but more importantly, affect the response speed of rescue. As an important social infrastructure, bridges require large investments and are highly public. Improving the seismic performance of bridges is one of the basic measures to reduce earthquake losses and strengthen regional safety. Seismic reinforcement is to improve the seismic performance of bridges so as to reduce earthquake disasters, prevent bridge damage, and control the damage to a certain extent.

The Chinese utility model patent application document with announcement number CN217499955U discloses an adjustable bridge seismic support that is easy to install, including a first mounting plate, four connecting blocks fixedly connected to the first mounting plate, and a second mounting plate fixedly connected to the side walls of the connecting blocks. Before use, the first mounting plate can be fixedly connected to the bridge. At this time, the limiting plates on the four second mounting plates will contact other steel components on the bridge, so that the fixing belt can be pulled to cause it to deform due to force, thereby changing its own angular position, so that the snap ring moves with it and snaps into engagement with the snap buckle. At this time, the limiting plate and the fixing belt will form a complete closed-loop structure to fix their own position with other steel components on the bridge.

The above technology will produce deformation and breakage during support and cannot effectively provide earthquake-resistant support. Therefore, it is urgent to design an adjustable bridge earthquake-resistant support to deal with these problems.

The bearing and shock absorbing mechanism 2 includes a first connecting plate platform 201 arranged on both sides of the mounting base 1, a positioning rod 202 is arranged on one side of the first connecting plate platform 201, and a mounting threaded hole is arranged on one side of the first connecting plate platform 201 for connecting the mounting screw. A first damping and shock absorbing spring device 203 is arranged on the front and rear sides above the mounting base 1, and the first damping and shock absorbing spring device 203 is used to provide shock absorbing support for the first bearing plate 205. An arc-shaped elastic sheet 204 is arranged on the opposite side of the first damping and shock absorbing spring device 203, and a first bearing plate 205 is arranged above the arc-shaped elastic sheet 204, and the arc-shaped elastic sheet 204 is used to support and shock absorb the first bearing plate 205. A first support platform 206 is arranged on the front and rear sides above the first bearing plate 205, and a moving guide assembly is arranged on the opposite side of the first support platform 206, and a supporting assembly is arranged on the outer surface of the moving guide assembly. The mobile guide assembly includes a guide cross column 207 arranged on the opposite side of the first support platform 206, and blocking rubber platforms 2072 are arranged at both ends of the guide cross column 207, and a spring 2071 is arranged on one side of the blocking rubber platform 2072. The blocking rubber platform 2072 is used to buffer and limit the spring 2071 when it is compressed. The support assembly includes a mobile support platform 208 arranged on the outer surface of the mobile guide assembly, and a guide groove 2081 is arranged below the mobile support platform 208. The guide groove 2081 is used to guide and limit the mobile support platform 208. A safety limit platform 209 is arranged on the opposite side of the support assembly. The safety limit platform 209 is a rubber member, which is used to buffer and reduce shock when the second bearing plate 304 moves downward.

The adjustable anti-seismic component 3 includes a second support platform 301 arranged on the front and rear sides above the bearing and damping mechanism 2, a column 302 is arranged inside the second support platform 301, a connecting plate 303 is arranged at one end of the column 302, a second bearing plate 304 is arranged above the connecting plate 303, a third support platform 305 is arranged on the front and rear sides above the second bearing plate 304, a first support shaft 306 is arranged horizontally inside the third support platform 305, a lifting assembly is arranged on one side of the first support shaft 306, and an anti-seismic support assembly 308 is arranged on one side of the lifting assembly. The lifting assembly includes a lifting hydraulic cylinder 307 arranged on one side of the first support shaft 306, and a second support shaft 3071 is arranged at the power telescopic end of the lifting hydraulic cylinder 307. The lifting assembly is used to drive the anti-seismic support assembly 308 to move up and down. The anti-seismic support assembly 308 includes a moving platform 3081 arranged on one side of the lifting assembly, a flower shaft 3082 is arranged on one side of the moving platform 3081, and a supporting load-bearing platform 3083 is arranged on the outer surface of the flower shaft 3082. A limit spring is arranged between the moving platform 3081 and the inside of the flower axis 3082. The supporting load-bearing platform 3083 cooperates with the flower axis 3082 to provide earthquake-resistant support for the bridge at a certain angle. The upper surface of the supporting load-bearing platform 3083 is provided with anti-skid and wear-resistant material, so that a certain contact friction is generated with the contact surface of the bridge.

When in use, first install the first connecting plate platforms 201 on both sides of the installation base 1 on the ground or pier surface under the bridge that needs earthquake support through the positioning rods 202, and use connecting screws to connect and fix. After the installation base 1 is fixed, start the lifting hydraulic cylinder 307 to drive the moving platform 3081 to rise a certain angle through the second support shaft 3071, and drive the supporting load-bearing platform 3083 to adjust a certain angle through the flower axis 3082 to support the bridge. The supporting load-bearing platform 3083 is simultaneously raised from the front and rear sides above the second bearing plate 304. Since the upper surface of the supporting load-bearing platform 3083 is provided with anti-slip and wear-resistant material, a certain contact friction is generated with the contact surface of the bridge, which can better support the supporting load-bearing platform 3083 to the bridge. For support, when the bridge vibrates, the vibration force is transmitted to the second bearing plate 304 through the seismic support assembly 308, and the second bearing plate 304 transmits the vibration force to the mobile support platform 208 through the column 302. When the mobile support platform 208 receives the vibration force, the vibration force drives the mobile support platform 208 to move toward each other on the outer surface of the guide cross column 207 and compresses the spring 2071. The vibration force is transmitted to the arc-shaped elastic sheet 204 and the first damping shock-absorbing spring device 203 through the first bearing plate 205. Since the arc-shaped elastic sheet 204 and the first damping shock-absorbing spring device 203 have good shock-absorbing and buffering stabilizing effects, the first bearing plate 205 remains stable, thereby increasing the supporting stability of the bridge and facilitating the stable use of the bridge.
