Description

Technical Field

[0001] The utility model relates to the technical field of seismograph testing tools, in particular to a vibration testing platform for a seismograph. Background Art

[0002] A seismograph is an instrument used to monitor seismic activity occurring on the surface or underground of the Earth. It is also called an earthquake monitoring instrument, seismometer or seismic instrument. A seismograph can record the vibration signals of seismic waves and transmit the data to a seismic monitoring center for analysis and processing. After the seismograph is manufactured, it is usually necessary to test it using a vibration test platform to ensure the accuracy of the seismograph.

[0003] However, the existing test platform usually only performs the test by ordinary vibration mode, which makes the test effect poor, thus may affect the test effect, so a vibration test platform for seismograph is proposed;

[0004] To this end, this case proposes a vibration test platform for seismographs to address the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a vibration test platform for a seismograph, which can effectively solve the technical problems in the background technology.

[0024] In this embodiment, an anti-skid pad 15 is disposed inside the clamping plate 14 , and the anti-skid pad 15 and the outside of the clamping plate 14 are both in an arc shape.

[0025] By providing the clamping plate 14 and the anti-skid pad 15 , the seismograph can be clamped for testing, and the anti-skid pad 15 and the outer portion of the clamping plate 14 are both in an arc-shaped state, so they can be applicable to seismographs of different sizes.

[0026] In this embodiment, a motor is disposed below the fixing plate 2 , the bottom of the motor is fixedly connected to the fixing frame 1 , and the output shaft of the motor is fixedly connected to the fixing plate 2 .

[0027] The motor is the output source of the entire device. When the motor is started, the fixed plate 2 rotates, thereby starting the vibration test.

[0028] In this embodiment, rubber ropes 11 are provided on both sides of the fixing frame 1 , and the rubber ropes 11 are fixedly connected to the storage plate 3 .

[0029] By providing the rubber rope 11 , the placement plate 3 can be limited to prevent the placement plate 3 from rotating, while the vibration of the placement plate 3 is not affected.

[0030] In this embodiment, a vertical rod 16 is provided between the fixed plate 2 and the storage plate 3, and the vertical rod 16 is movably connected to the fixed plate 2. A sleeve 7 is provided above the vertical rod 16, and a ball 10 is provided outside the sleeve 7. The ball 10 is movably connected to the sleeve 7.

[0031] In this embodiment, six groups of movable components 17 are arranged between the fixed plate 2 and the storage plate 3, and the six groups of movable components 17 are arranged at equal distances.
