Description

Technical Field

[0001] The invention relates to the technical field of displacement measurement, in particular to a tool used for measuring the displacement of a seismic isolation support. Background Art

[0002] Seismic isolation bearings refer to the supporting devices set up in the structure to meet the seismic isolation requirements. They are to add a seismic isolation layer between the upper structure and the foundation, install rubber seismic isolation bearings, and play a soft connection with the ground. Through this technology, about 80% of the energy of the earthquake can be offset. At present, the commonly used seismic isolation method is rubber seismic isolation bearings. Seismic isolation bearings are subject to complex self- and environmental load effects during construction and use, which inevitably produce structural system damage accumulation, resulting in a decrease in its ability to resist natural disasters, which not only affects the normal use of the bearing structure, but also brings certain safety hazards to the building; In the prior art, the rubber seismic isolation bearing is installed at the bottom of the building. After the seismic isolation bearing is installed, the construction workers will carry out layered and segmented construction of the main building above the seismic isolation bearing. As the main building is constructed, the pressure applied to the seismic isolation bearing will gradually increase, causing the seismic isolation bearing to be displaced. However, the deformation displacement of the seismic isolation bearing is a composite motion, which includes displacement components in three directions: x, y, and z. Most existing measuring devices are unidirectional measuring devices, which cannot fully reflect the overall displacement of the seismic isolation bearing. In addition, the existing technology mainly uses linear displacement sensors to measure in the three directions of x, y, and z during the monitoring process. The plural use of linear displacement sensors makes the device susceptible to the influence of the external construction environment in the actual use environment, resulting in damage to the measuring device, thereby affecting the accuracy of the displacement measurement.

[0027] Further Embodiments See also Figure 4 , Figure 6 and Fig.10 The tooling for measuring the displacement of the seismic isolation support further includes a displacement feedback component arranged on the positioning ring 43: The displacement feedback assembly includes a fixed rod 51 fixedly installed on the outer wall of the positioning ring 43, the fixed rod 51 is fixedly connected to a displacement change reaction platform 52 at one end away from the positioning ring 43, a self-locking telescopic rod 53 is fixedly connected to the upper surface of the displacement change reaction platform 52, and the self-locking telescopic rod 53 is fixedly connected to a mounting gasket 54 at one end away from the displacement change reaction platform 52.

[0029] Among them, the fixed rod 51 is set as a retractable structure.

[0030] The working process and principle of the overall content of the above embodiment are as follows: Installation of the device: After the staff has installed the seismic isolation support body 11, they will then place the L-shaped fixed mounting frame 12 at one corner of the seismic isolation support body 11. During installation, the staff will need to align the two end edges of the L-shaped fixed mounting frame 12 with the edge of the seismic isolation support body 11 to keep them parallel, and ensure that the metal gasket 13 fixedly installed on the edge of the L-shaped fixed mounting frame 12 fits the surface of the seismic isolation support body 11. The staff can then fix the metal gasket 13 on the seismic isolation support body 11 through bolts and other components, and fix the L-shaped fixed mounting frame 12 to the seismic isolation support body 11 through the bolts and the metal gasket 13. Then the staff needs to adjust the length of the self-locking telescopic rod 53, move the installation gasket 54 at the top of the self-locking telescopic rod 53 to a state of being in contact with the lower surface of the top of the seismic isolation support body 11, and then fix the installation gasket 54 on the seismic isolation support body 11 with bolts; It should be noted that, in the initial state, the displacement change reaction platform 52 located at the bottom end of the self-locking telescopic rod 53 is in a horizontal state under the joint action of the X-direction connecting rod 24, the Y-direction connecting rod 34 and the fixed rod 51. When displacement changes occur at the upper and lower ends of the seismic isolation bearing body 11, the specific displacement data will be transmitted through the displacement change reaction platform 52, and the staff can obtain the specific displacement of the seismic isolation bearing body 11 by observing the changes in the data before and after.

[0031] Displacement direction setting of displacement measurement tooling: The direction of the X-direction moving groove 21 on the L-shaped fixed mounting frame 12 is set as the X-axis, and the direction of the Y-direction moving groove 31 on the L-shaped fixed mounting frame 12 is set as the Y-axis. The intersection of the X-axis and the extended line of the Y-axis is the installation position of the Z-direction positioning rod 41, that is, the Z-direction positioning rod 41 is set as the Z-axis; Since the displacement change of the seismic isolation support body 11 involves the three directions of X, Y, and Z during actual use, and scales are set on the L-shaped fixed mounting frame 12 and the positioning rod in the Z direction, it is necessary to determine the initial position of the seismic isolation support body 11 when it is not deformed, that is, to determine the initial values ​​of the displacement change reaction platform 52 in the three directions of X, Y, and Z, and set these three initial values ​​to X0, Y0, and Z0 respectively; In the X direction, in the initial state, the X direction moving block 22 is in a balanced state in the X direction moving groove 21 under the joint action of the X direction positioning spring 25 and the X direction traction spring 26. At this time, the position of the X direction scale pointer 23 set on the X direction moving block 22 is recorded as X0. At this time, the number indicated by the X direction scale pointer 23 is 0, and the scale value on the L-shaped fixed mounting frame 12 is recorded as a negative value along the direction of the X direction moving block 22 to the turning point of the L-shaped fixed mounting frame 12 with the X0 position as the base point, and is recorded as a positive value along the direction of the X direction moving block 22 away from the L-shaped fixed mounting frame 12 with the X0 position as the base point; In the Y direction, in the initial state, the Y direction moving block 32 is in a balanced state in the Y direction moving groove 31 under the joint action of the Y direction positioning spring 35 and the Y direction traction spring 36. At this time, the position of the Y direction scale pointer 33 set on the Y direction moving block 32 is recorded as Y0. At this time, the number indicated by the Y direction scale pointer 33 is 0, and the scale value on the L-shaped fixed mounting frame 12 is recorded as a negative value along the Y direction moving block 32 to the turning point of the L-shaped fixed mounting frame 12 with the Y0 position as the base point, and is recorded as a positive value along the Y direction moving block 32 away from the L-shaped fixed mounting frame 12 with the Y0 position as the base point; In the Z direction, in the initial state, the positioning ring 43 is kept in a balanced state on the Z direction positioning rod 41 under the joint action of the connecting rod 1 45, the connecting rod 2 46 and the connecting spring 47. In this state, the position indicated by the Z direction scale pointer 44 set on the positioning ring 43 is set to Z0. At this time, the number indicated by the Z direction scale pointer 44 is 0, and the Z direction positioning rod 41 is set to a positive value along the upward direction of the positioning ring 43 and a negative value along the downward direction of the positioning ring 43.

[0032] Use of displacement monitoring device: When the seismic isolation support body 11 undergoes displacement changes during use, it is specifically manifested in that the upper and lower ends of the seismic isolation support body 11 move in an indefinite direction from the original parallel state. Due to the relative displacement of the upper and lower ends of the seismic isolation support, the self-locking telescopic rod 53 fixedly installed on the top lower surface of the seismic isolation support body 11 through the installation gasket 54 will also change position accordingly, and this change will be fed back to the displacement change reaction platform 52 through the self-locking telescopic rod 53; Since the displacement change reaction platform 52 maintains a balanced state under the joint action of the X-direction connecting rod 24, the Y-direction connecting rod 34 and the fixed rod 51 in the initial state, when the displacement change reaction platform 52 changes, it will act on the X-direction connecting rod 24, the Y-direction connecting rod 34 and the fixed rod 51 through the displacement change reaction platform 52; In the above process, the displacement change in the X direction is transmitted to the X direction moving block 22 through the X direction connecting rod 24. Since the X direction connecting rod 24 is rotatably connected to the X direction moving block 22, when the X direction connecting rod 24 moves under the action of the displacement change reaction platform 52, the X direction moving block 22 is driven by the X direction connecting rod 24 to move in the X direction moving groove 21 toward the turning point of the L-shaped fixed mounting frame 12 or toward the turning point away from the L-shaped fixed mounting frame 12. When the X-direction moving block 22 moves in the X-direction moving groove 21 toward the turning point close to the L-shaped fixed mounting frame 12, the movement of the X-direction moving block 22 compresses the X-direction traction spring 26 and stretches the X-direction positioning spring 25. In this moving state, the X-direction scale pointer 23 set on the X-direction moving block 22 indicates a negative value. When the X-direction moving block 22 moves in the X-direction moving groove 21 toward the turning point away from the L-shaped fixed mounting frame 12, the movement of the X-direction moving block 22 stretches the X-direction traction spring 26 and compresses the X-direction positioning spring 25. In this moving state, the X-direction scale pointer 23 set on the X-direction moving block 22 indicates a positive value. It should be noted that the X-direction moving block 22 will synchronously drive the X-direction clamping rod 28 connected thereto to move synchronously during the movement. Since the X-direction tooth blocks 27 are equidistantly fixedly connected to the L-shaped fixed mounting frame 12, and a torsion spring is fixedly connected between the X-direction clamping rod 28 and the X-direction moving block 22, the movement of the X-direction moving block 22 will synchronously drive the X-direction clamping rod 28 to move. The X-direction clamping rod 28 will continuously contact the X-direction tooth blocks 27 during the movement. Since the X-direction clamping rod 28 is composed of two short rods that are obliquely symmetrically arranged and a long rod arranged therebetween, the X-direction clamping rod 28 will move synchronously during the movement. The short rod inclined at one end of the rod 28 in the moving direction will contact with the X-direction tooth block 27 and be squeezed by the X-direction tooth block 27. The X-direction clamping rod 28 will be squeezed by the X-direction tooth block 27 and deflected by the connection point between the X-direction clamping rod 28 and the X-direction moving block 22 as a fulcrum, and the end will move upward until the X-direction clamping rod 28 is out of contact with the X-direction tooth block 27. When the X-direction clamping rod 28 continues to move, the squeezing force of the X-direction clamping rod 28 from the previous X-direction tooth block 27 disappears, and the X-direction clamping rod 28 is restored to its initial state by the rebound effect of the torsion spring. The movement trajectory of the above-mentioned X-direction clamping rod 28 will reciprocate with the movement of the X-direction moving block 22. The displacement change in the Y direction is transmitted to the Y direction moving block 32 through the Y direction connecting rod 34. Since the Y direction connecting rod 34 is rotatably connected to the Y direction moving block 32, when the Y direction connecting rod 34 moves under the action of the displacement change reaction platform 52, the Y direction moving block 32 is driven by the Y direction connecting rod 34 to move in the Y direction moving groove 31 toward the turning point of the L-shaped fixed mounting frame 12 or toward the turning point away from the L-shaped fixed mounting frame 12. When the Y-direction moving block 32 moves in the Y-direction moving groove 31 toward the turning point close to the L-shaped fixed mounting frame 12, the movement of the Y-direction moving block 32 compresses the Y-direction traction spring 36 and stretches the Y-direction positioning spring 35. In this moving state, the Y-direction scale pointer 33 set on the Y-direction moving block 32 indicates a negative value. When the Y-direction moving block 32 moves in the Y-direction moving groove 31 toward the turning point away from the L-shaped fixed mounting frame 12, the movement of the Y-direction moving block 32 stretches the Y-direction traction spring 36 and compresses the Y-direction positioning spring 35. In this moving state, the Y-direction scale pointer 33 set on the Y-direction moving block 32 indicates a positive value. It should be noted that the Y-direction moving block 32 will synchronously drive the Y-direction clamping rod 38 connected thereto to move synchronously during the movement. Since the Y-direction tooth blocks 37 are equidistantly fixedly connected to the L-shaped fixed mounting frame 12, and a coil spring is fixedly connected between the Y-direction clamping rod 38 and the Y-direction moving block 32, the movement of the Y-direction moving block 32 will synchronously drive the Y-direction clamping rod 38 to move. The Y-direction clamping rod 38 will continuously contact the Y-direction tooth block 37 during the movement. Since the Y-direction clamping rod 38 is composed of two short rods arranged obliquely and symmetrically and a long rod arranged therebetween, the Y-direction clamping rod 38 will rotate synchronously during the movement. The short rod inclined at one end of the rod 38 in the moving direction will contact with the Y-direction tooth block 37 and be squeezed by the Y-direction tooth block 37. The Y-direction clamping rod 38 will be squeezed by the Y-direction tooth block 37 and deflected by the connection point between it and the Y-direction moving block 32 as a fulcrum, and the end will move upward until the Y-direction clamping rod 38 is out of contact with the Y-direction tooth block 37. When the Y-direction clamping rod 38 continues to move, the squeezing force from the previous Y-direction tooth block 37 on the Y-direction clamping rod 38 disappears, and the Y-direction clamping rod 38 is restored to its initial state by the rebound effect of the coil spring. The movement trajectory of the above-mentioned Y-direction clamping rod 38 will reciprocate with the movement of the Y-direction moving block 32. It should be noted that, since the fixed rod 51 is configured as a retractable structure, when the displacement change reaction platform 52 is displaced in the X direction or the Y direction, the length of the fixed rod 51 will also change accordingly to adapt to the movement of the displacement change reaction platform 52, and the length of the fixed rod 51 will not affect the movement of the displacement change reaction platform 52; Since the working application scene is mostly construction sites with a relatively messy environment, the use of sensors for monitoring in actual use is easily affected by the external environment, which may lead to errors in the monitoring data. Through the arrangement of the X-direction clamping rod 28, the X-direction tooth block 27, the Y-direction clamping rod 38 and the Y-direction tooth block 37, when the seismic isolation bearing body 11 produces displacement in the X-axis direction or the Y-axis direction, the cooperation of the X-direction clamping rod 28, the X-direction tooth block 27, the Y-direction clamping rod 38 and the Y-direction tooth block 37 will reversely limit the position of the X-direction moving block 22 and the Y-direction moving block 32, thereby avoiding the X-direction moving block 22 and the Y-direction moving block 32 from being displaced in the actual It is affected by other objects during use. At the same time, since a torsion spring and a rotational connection are provided between the X-direction clamping rod 28 and the X-direction moving block 22, and a disc spring and a rotational connection are provided between the Y-direction clamping rod 38 and the Y-direction moving block 32, when the displacement of the seismic isolation support body 11 changes, since the mass of the building stacked on the seismic isolation support body 11 is very large, the coordination of the X-direction clamping rod 28, the X-direction tooth block 27, the Y-direction clamping rod 38 and the Y-direction tooth block 37 will not affect the displacement data of the seismic isolation support body 11, thereby ensuring the accuracy of the displacement data monitoring of the seismic isolation support body 11; The displacement change in the Z direction is transmitted to the positioning ring 43 through the displacement change reaction platform 52. When the displacement change platform is displaced in the Z direction along with the seismic isolation support body 11, the positioning ring 43 is driven by the fixing rod 51 to move upward or downward along the guide rail 42 on the Z direction positioning rod 41. During the above process, the Z-direction scale pointer 44 disposed on the upper and lower surfaces of the positioning ring 43 will move accordingly, and then cooperate with the scale disposed on the Z-direction positioning rod 41. The staff can quickly obtain the Z-axis displacement data of the seismic isolation bearing through the data indicated by the Z-direction scale pointer 44; During the movement of the positioning ring 43, the connecting rod 1 45 rotatably connected to the two ends of the positioning ring 43 will move accordingly, and because the end of the connecting rod 1 45 away from the positioning ring 43 is rotatably connected to the connecting rod 2 46, and the end of the connecting rod 2 46 away from the connecting rod 1 45 is rotatably connected to the Z-direction positioning rod 41, the movement of the positioning ring 43 will drive the connecting rod 1 45 and the connecting rod 2 46 to move synchronously, stretching or contracting in the Z-axis direction, and at this time, the connecting spring 47 arranged between the connecting rod 1 45 and the connecting rod 2 46 will stretch or contract accordingly; Through the arrangement of the connecting rod 1 45, the connecting rod 2 46 and the connecting spring 47, when the seismic isolation support body 11 is displaced in the Z-axis direction, the movement of the positioning ring 43 in the Z-direction positioning rod 41 is jointly restricted by the connecting rod 1 45, the connecting rod 2 46 and the connecting spring 47, so as to keep the positioning ring 43 balanced during the movement, and avoid the situation that the positioning ring 43 is deflected and stuck during the movement, thereby ensuring the accuracy of the positioning ring 43 and the Z-direction scale pointer 44 in indicating the Z-axis displacement of the seismic isolation support; After the displacement monitoring of the seismic isolation support body 11 is completed, the staff can remove the metal gasket 13 and the mounting gasket 54 from the seismic isolation support body 11. At this time, the traction of the upper and lower ends of the seismic isolation support body 11 is lost, and the displacement change reaction platform 52 will restore to its initial state under the action of the rebound of the X-direction positioning spring 25, the X-direction traction spring 26, the Y-direction positioning spring 35, the Y-direction traction spring 36 and the connecting spring 47. When the X-direction positioning spring 25, the X-direction traction spring 26, the Y-direction positioning spring 35, the Y-direction traction spring 36 and the connecting spring 47 are damaged, that is, at this time, the X-direction scale pointer 23, the Y-direction scale pointer 33 and the Z-direction scale pointer 44 indicate positions other than the X0, Y0 and Z0 positions after recovery, at this time, it is only necessary to replace the X-direction positioning spring 25, the X-direction traction spring 26, the Y-direction positioning spring 35, the Y-direction traction spring 36 and the connecting spring 47 with the same elastic coefficient.

[0033] By setting up the X-direction displacement monitoring component, the Y-direction displacement monitoring component, and the Z-direction displacement monitoring component, the staff can quickly learn about the displacement status of the seismic isolation support body 11 during actual use. Compared with the traditional multi-sensor setting, the tooling can avoid the problem of easy damage during use in the actual construction site environment, and is easy to use while reducing the cost of monitoring the displacement data of the seismic isolation support body 11; Through the detachable setting of the metal gasket 13 and the mounting gasket 54 and the retractable setting of the self-locking telescopic rod 53, the tooling can be reused in actual use and installed on seismic isolation bearing bodies 11 of different sizes, thereby reducing the demand for corresponding displacement measurement tooling for seismic isolation bearing bodies 11 of different sizes and reducing the cost of use.
