All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figures 1 to 4 This utility model provides a technical solution: a seismic isolation bearing tensile strength testing device, including a mounting plate 1, with hydraulic push rods 101 fixedly connected to both sides of the top of the mounting plate 1, and a lifting beam frame 102 fixedly connected to the top of the two hydraulic push rods 101, with a loading component 2 installed on the side of the mounting plate 1 opposite to the lifting beam frame 102, and a seismic isolation bearing 103 set on the side of the loading component 2 opposite to the mounting plate 1, with a steel plate fixedly connected to the top and bottom of the seismic isolation bearing 103, and multiple round holes opened on the surface of the steel plate;

[0031] The loading assembly 2 includes fixed plates 201 respectively fixedly connected to the mounting plate 1 and the opposite side of the lifting beam frame 102. Loading plates 202 are fixedly connected to the opposite sides of each fixed plate 201. Slide grooves are formed on all four sides of the loading plates 202. A slider 203 is slidably connected to the inner wall of each slide groove. An L-shaped clamp 204 is fixedly connected to the top of each slider 203. A motor 205 is fixedly connected to the top of the fixed plates 201. A transmission rod is splined to the output end of the motor 205. A turntable 206 is fixedly connected to one end of the transmission rod. The edges of the turntable 206 are respectively connected to the four sliders 203.

With the arrangement of loading plate 202, slider 203, L-shaped clamping plate 204, motor 205, turntable 206 and connecting rod 207, when loading the seismic isolation support 103, the motor 205 is started first to drive the turntable 206 to rotate. The rotation of the turntable 206 causes the connecting rod 207 to pull the four slide blocks 203 to slide in the grooves on the four sides of the loading plate 202, so that they move towards the steel plate at the same time. Then, the four L-shaped clamping plates 204 clamp the steel plate at the same time, effectively preventing the seismic isolation support 103 from shaking or displacing during the testing process, and ensuring the safety and stability of the testing process.

[0032] The shock-absorbing assembly 3 includes a movable shell 301 fixedly connected to the bottom of the mounting plate 1. A base 302 is movably connected to the inner surface of the movable shell 301. A support plate 303 is fixedly connected to the bottom of the base 302. A mounting block 304 is fixedly connected to the bottom of the mounting plate 1. A groove is formed on the top of the base 302.

The shock-absorbing assembly 3 is connected to the base 302 and the base 303. 02. The arrangement of mounting block 304, sliding block 305, spring 306 and hinge rod 307 is such that when the device is impacted, the mounting plate 1 will move first, causing the mounting block 304 to move as well. This causes the sliding block 305 to slide in the groove of the base 302 via the hinge rod 307. During the sliding process, the spring 306 will be compressed or stretched, converting the impact kinetic energy of the device into the elastic potential energy of the spring 306, and then slowly releasing it. This can quickly and effectively reduce the vibration of the device, protect the internal components of the device from impact damage, and extend the service life of the device.

[0033] C-shaped shells 5 are fixedly connected to both sides of the top of the mounting plate 1. The C-shaped shells 5 ensure the stability of the lifting beam frame 102 when it moves. The inner surface of the C-shaped shells 5 is in contact with one side of the lifting beam frame 102. A prompting component 4 is installed on one side of the C-shaped shells 5.

The positioning blocks 7 are adapted to the round holes of the steel plate.

[0036] A protective pad 8 is fixedly connected to the top of the base 302. With the setting of the protective pad 8, the protective pad 8 can reduce the noise generated by the contact between the object and the base 302 or the operation of the device. The material of the protective pad 8 is rubber.

[0037] The inner surface of the L-shaped clamp 204 is fixedly connected with an anti-slip pad 9. The anti-slip pad 9 can make the L-shaped clamp 204 more secure when clamping objects. The surface of the anti-slip pad 9 is provided with anti-slip texture.

[0038] In this invention, the working steps of the device are as follows:

[0039] First step: First, start the motor 205 to drive the turntable 206 to rotate. The rotation of the turntable 206 causes the connecting rod 207 to pull the four sliders 203 to slide in the grooves on the four sides of the loading plate 202, so that they move towards the steel plate at the same time. This causes the four L-shaped clamps 204 to clamp the steel plate at the same time, effectively preventing the vibration isolation support 103 from shaking or displacing during the test, and ensuring the safety and stability of the test process.

[0040] The second step: The mounting plate 1 will move, which will also move the mounting block 304. This will cause the sliding block 305 to slide in the groove of the base 302 through the hinge rod 307. During the sliding process, the spring 306 will be compressed or stretched, converting the impact kinetic energy of the device into the elastic potential energy of the spring 306, and then slowly releasing it. This can quickly and effectively reduce the vibration of the device, protect the internal components of the device from impact damage, and extend the service life of the device.
