Problems solved by technology

[0002] When using the pseudo-static test method to test the vertical stiffness of the isolation rubber bearing, etc., the displacement generally uses a very high-precision contact displacement sensor, and the measured signal is transmitted to the computer through the signal line and recorded as readable. The written data file can be processed by program and the vertical stiffness of the support can be obtained, but the height of some vibration-isolation rubber bearings is small, and the height of the displacement sensor itself exceeds the height of the support when it is in contact. The test of the vertical stiffness of similar bearings may be unable to test because the sensor cannot be placed; , its vertical displacement will be very small, which may not be measured by the above-mentioned contact displacement sensor, and the imported ultra-high precision displacement sensor is very expensive

Embodiment 1

[0032] Such as Figure 1-5 As shown, the novel displacement sensor conversion and amplifying device of the present embodiment includes a base 1 on which a conversion slope 2 is slidably arranged, and a horizontal displacement meter 3 is also arranged on the base 1, and the horizontal displacement The meter 3 abuts against the vertical surface 21 of the conversion bevel body 2, and also includes a vertical pointer 4, and the vertical pointer 4 is slidingly connected with the slope 22 of the conversion bevel body 2, wherein the conversion bevel body The inclination angle of the inclined surface 22 of 2 and the horizontal plane is 45 °.

[0033] The novel displacement sensor conversion and amplifying device of the present embodiment only has the effect of displacement conversion. In the process of using, at first the device is placed between the upper base plate 5 and the lower base plate 6 of the test equipment, and the vertical pointer 4 The tail part is connected with the bot...

Embodiment 2

[0040] Such as Figure 6-7 As shown, the difference between this embodiment and Embodiment 1 is that: the inclination angle between the inclined surface 22 of the conversion inclined plane body 2 and the horizontal plane is less than 45°. The new displacement sensor conversion and amplification device of this embodiment has the functions of displacement conversion and displacement amplification. Its installation and operation process is the same as that of Embodiment 1. The vertical displacement of the test body will be amplified, and its amplification factor depends on the ratio of the maximum height of the bottom of the inclined plane to the vertical projection length of the inclined plane; The vertical pointer 4 of the amplifying device moves upward, and the probe 32 of the horizontal contact sensor is provided with a spring, and the spring will elongate at this time, thereby pushing the inclined-plane conversion body to move away from the horizontal displacement meter 3, t...

Abstract

The invention relates to the technical field of experiments and tests, and discloses a novel displacement sensor transformation and amplification device which comprises a base. A transformation clinohedral is arranged on the base in a sliding mode, a horizontal displacement meter is arranged on the base, and the horizontal displacement meter is in butt joint with the vertical face of the transformation clinohedral. The device further comprises a vertical pointer, and the vertical pointer is in sliding connection with the inclined face of the transformation clinohedral. According to a transformation device body, vertical displacement can be transformed into horizontal displacement in an equivalent mode, and according to an amplification device body, the ratio of different end heights to the horizontal projection length of the inclined face can be set to adjust amplification factors. The device can be used for pseudo-static tests of supports and other test pieces with the small height or quite small vertical deformation, can be used for pseudo-dynamic tests, seismic modeling tests and static tests, and is wide in application range and high in practicality. The device can be directly mounted on the periphery of the supports and the other test pieces, the vertical pointer and the base of the device are connected with an upper bottom plate and a lower bottom plate of equipment respectively through bolts or magnets, and the device can be used repeatedly.
