Description

Technical Field

[0001] The present invention relates to the technical field of displacement measurement, and specifically provides a tooling for measuring the displacement of seismic isolation bearings. Background Art

[0002] A seismic isolation bearing refers to a supporting device provided to meet the seismic isolation requirements of a structure. An isolation layer is added between the superstructure and the foundation, and a rubber seismic isolation bearing is installed to achieve a soft connection with the ground. Through such technology, about 80% of the seismic energy can be offset. Currently, the commonly used seismic isolation method is the rubber seismic isolation bearing. During the construction and use of the seismic isolation bearing, it is affected by complex self and environmental load effects, inevitably resulting in the accumulation of structural system damage, leading to a decline in its ability to resist natural disasters, which not only affects the normal use of the bearing structure but also poses certain safety hazards to the building.

[0003] In the prior art, the rubber seismic isolation bearing is installed at the bottom end of the building. After the installation of the seismic isolation bearing is completed, construction workers will carry out layered and segmented construction of the building main body above the seismic isolation bearing. As the construction of the building main body progresses, the pressure applied to the seismic isolation bearing will gradually increase, resulting in displacement of the seismic isolation bearing.

[0004] However, the deformation displacement of the seismic isolation bearing is a complex motion, which includes displacement components in the x, y, and z directions. Most of the existing measurement devices are single-direction measurement devices and cannot comprehensively reflect the overall displacement of the seismic isolation bearing. Moreover, in the prior art, during the monitoring process, linear displacement sensors are mainly used to measure in the x, y, and z directions respectively. The multiple use of linear displacement sensors makes the device vulnerable to the influence of the external construction environment in the actual use environment, resulting in damage to the measurement device, thus affecting the accuracy of displacement measurement.

[0005] In view of this, we propose a tooling for measuring the displacement of seismic isolation bearings to solve the above problems. Summary of the Invention

[0024] Through the settings of the X-direction clamping rod, X-direction gear block, Y-direction clamping rod and Y-direction gear block, when the isolation bearing body generates displacement in the X-axis direction or Y-axis direction, the cooperation of the X-direction clamping rod, X-direction gear block, Y-direction clamping rod and Y-direction gear block will restrict the positions of the X-direction moving block and Y-direction moving block in the reverse direction, avoiding the influence of other objects on the X-direction moving block and Y-direction moving block during actual use. At the same time, due to the setting of the torsion spring between the X-direction clamping rod and the X-direction moving block and the rotational connection between them, and the setting of the disc spring between the Y-direction clamping rod and the Y-direction moving block and the rotational connection between them, when the displacement of the isolation bearing body changes, due to the large mass of the building stacked on the isolation bearing body, the cooperation of the X-direction clamping rod, X-direction gear block, Y-direction clamping rod and Y-direction gear block will not affect the displacement data of the isolation bearing body, thus ensuring the accuracy of the displacement data monitoring of the isolation bearing body;

[0025] Through the settings of the first connecting rod, the second connecting rod and the connecting spring, when the isolation bearing body generates displacement in the Z-axis direction, the movement of the positioning ring on the Z-direction positioning rod is jointly restricted by the first connecting rod, the second connecting rod and the connecting spring, maintaining the balance of the positioning ring during the movement and avoiding the situation of skew jamming during the movement of the positioning ring, so as to ensure the accuracy of the Z-axis displacement of the isolation bearing indicated by the positioning ring and the Z-direction scale pointer;

[0026] Through the settings of the X-direction displacement monitoring component, Y-direction displacement monitoring component and Z-direction displacement monitoring component, the staff can quickly know the displacement condition of the isolation bearing body during actual use. Compared with the traditional multi-sensor setting, this tooling can avoid the problem of easy damage during the actual construction site environment use, facilitating the use and reducing the cost of monitoring the displacement data of the isolation bearing body;

[0027] Through the detachable settings of the metal gasket and the installation gasket and the telescopic setting of the self-locking telescopic rod, this tooling can be reused during actual use and installed on isolation bearing bodies of different sizes, thus reducing the demand for corresponding displacement measurement tooling for isolation bearing bodies of different sizes and reducing the use cost.

[0059] Further embodiments

[0060] Please refer to Figure 4 、 Figure 6 and Figure 10 For the tooling for measuring the displacement of the seismic isolation bearing, it further includes a displacement feedback component arranged on the positioning ring 43:

[0061] The displacement feedback component includes a fixed rod 51 fixedly installed on the outer wall of the positioning ring 43. One end of the fixed rod 51 far from the positioning ring 43 is fixedly connected with a displacement change reaction platform 52. A self-locking telescopic rod 53 is fixedly connected to the upper surface of the displacement change reaction platform 52. One end of the self-locking telescopic rod 53 far from the displacement change reaction platform 52 is fixedly connected with a mounting gasket 54.

[0062] Among them, one end of the X-direction connecting rod 24 far from the X-direction moving block 22 is rotatably connected to the bottom end of the displacement change reaction platform 52.

[0063] Among them, the fixed rod 51 is set as a telescopic structure. When the displacement change reaction platform 52 has a displacement 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.

[0064] The working process and principle of the overall content of the above embodiments are as follows:

[0065] Installation of the device:

[0066] After the staff installs the seismic isolation bearing body 11, then place the L-shaped fixed mounting frame 12 at one corner of the seismic isolation bearing body 11. When installing, the staff needs to align the two ends of the L-shaped fixed mounting frame 12 with the edges of the seismic isolation bearing body 11 to keep it in a parallel state, and ensure that the metal gasket 13 fixedly installed on the edge of the L-shaped fixed mounting frame 12 is attached to the surface of the seismic isolation bearing body 11. Then the staff can fixedly install the metal gasket 13 on the seismic isolation bearing body 11 through bolts and other components, and fixedly connect the L-shaped fixed mounting frame 12 and the seismic isolation bearing body 11 through bolts and the metal gasket 13;

[0067] Subsequently, the staff needs to adjust the length of the self-locking telescopic rod 53, move the mounting gasket 54 at the top of the self-locking telescopic rod 53 to a state where it fits the lower surface of the top of the seismic isolation bearing body 11, and then fix and install the mounting gasket 54 on the seismic isolation bearing body 11 through bolts;

[0068] It should be noted that in the initial state, the displacement change reaction platform 52 at the bottom end of the self-locking telescopic rod 53 is in a horizontal state under the combined 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 situation of the seismic isolation bearing body 11 by observing the changes in the data before and after.

[0069] Displacement direction setting of the displacement measurement tooling:

[0070] Set the direction along the X-direction moving slot 21 on the L-shaped fixed mounting frame 12 as the X-axis, set the direction along the Y-direction moving slot 31 on the L-shaped fixed mounting frame 12 as the Y-axis, and the intersection point of the extension lines of the X-axis and the Y-axis is the installation position of the Z-direction positioning rod 41, that is, set the Z-direction positioning rod 41 as the Z-axis;

[0071] Since the displacement change of the seismic isolation bearing body 11 involves three directions of X, Y, and Z during actual use, and there are scales on both the L-shaped fixed mounting frame 12 and the Z-direction positioning rod, it is necessary to determine the initial position when the seismic isolation bearing body 11 has not deformed, that is, to determine the initial values of the displacement change reaction platform 52 in the X, Y, and Z directions, and set these three initial values as X 0 、Y 0 、Z 0 ;

[0072] In the X direction, in the initial state, the X-direction moving block 22 is in a balanced state in the X-direction moving slot 21 under the combined action of the X-direction positioning spring 25 and the X-direction traction spring 26. At this time, record the position where the X-direction scale pointer 23 set on the X-direction moving block 22 as X 0 , and at this time, the number indicated by the X-direction scale pointer 23 is 0. Then, the scale values on the L-shaped fixed mounting frame 12 are recorded as negative values along the direction from the X-direction moving block 22 to the turning point of the L-shaped fixed mounting frame 12 with X 0 as the base point, and are recorded as positive values along the direction away from the L-shaped fixed mounting frame 12 on the side of the X-direction moving block 22 with X 0 as the base point;

[0073] In the Y direction, in the initial state, the Y-direction moving block 32 is in a balanced state within the Y-direction moving groove 31 under the combined action of the Y-direction positioning spring 35 and the Y-direction traction spring 36. At this time, the position where the Y-direction scale pointer 33 provided on the Y-direction moving block 32 is denoted as Y 0 , and the number indicated by the Y-direction scale pointer 33 is 0 at this time. Then, the scale value on the L-shaped fixed mounting bracket 12 is denoted as negative along the direction from the Y-direction moving block 32 to the turning point of the L-shaped fixed mounting bracket 12 with Y 0 as the base point, and is denoted as positive along the direction away from the L-shaped fixed mounting bracket 12 on one side of the Y-direction moving block 32 with Y 0 as the base point;

[0074] In the Z direction, in the initial state, the positioning ring 43 is in a balanced state on the Z-direction positioning rod 41 under the combined action of the first connecting rod 45, the second connecting rod 46, and the connecting spring 47. In this state, the position indicated by the Z-direction scale pointer 44 provided on the positioning ring 43 is set as Z 0 , and the number indicated by the Z-direction scale pointer 44 is 0 at this time. Then, the direction upward along the positioning ring 43 on the Z-direction positioning rod 41 is set as positive, and the direction downward along the positioning ring 43 is set as negative.

[0075] Use of the displacement monitoring device:

[0076] When displacement changes occur during the specific use of the seismic isolation bearing body 11, it is specifically manifested as the indefinite-direction movement of the upper and lower ends of the seismic isolation bearing body 11 from the original parallel state. Due to the relative displacement between the upper and lower ends of the seismic isolation bearing, at this time, the self-locking telescopic rod 53 fixedly installed on the lower surface of the top of the seismic isolation bearing body 11 through the mounting gasket 54 will also change its position accordingly, and then this change will be fed back to the displacement change reaction platform 52 through the self-locking telescopic rod 53;

[0077] Since the displacement change reaction platform 52 is in a balanced state under the combined 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 undergoes a displacement change, 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;

[0078] 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, it will drive the X-direction moving block 22 to move within the X-direction moving groove 21 in the direction approaching the turning point of the L-shaped fixed mounting bracket 12 or in the direction away from the turning point of the L-shaped fixed mounting bracket 12;

[0079] When the X-direction moving block 22 moves inside the X-direction moving slot 21 towards the turning point of the L-shaped fixed mounting bracket 12, the movement of the X-direction moving block 22 will compress the X-direction traction spring 26 and stretch the X-direction positioning spring 25. In this motion state, the X-direction scale pointer 23 provided on the X-direction moving block 22 indicates a negative value;

[0080] When the X-direction moving block 22 moves inside the X-direction moving slot 21 away from the turning point of the L-shaped fixed mounting bracket 12, the movement of the X-direction moving block 22 will stretch the X-direction traction spring 26 and compress the X-direction positioning spring 25. In this motion state, the X-direction scale pointer 23 provided on the X-direction moving block 22 indicates a positive value;

[0081] It should be noted that during the movement of the X-direction moving block 22, it will synchronously drive the X-direction latch 28 rotatably connected inside it to move synchronously. Since the X-direction tooth blocks 27 are fixedly connected at equal intervals on the L-shaped fixed mounting bracket 12, and a torsion spring is fixedly connected between the X-direction latch 28 and the X-direction moving block 22, the movement of the X-direction moving block 22 will synchronously drive the X-direction latch 28 to move. During the movement of the X-direction latch 28, it will continuously contact the X-direction tooth blocks 27. Since the X-direction latch 28 is composed of two symmetrically inclined short rods and a long rod arranged between them, during the movement of the X-direction latch 28, the short rod with an inclined setting at one end of the moving direction of the X-direction latch 28 will contact the X-direction tooth block 27 and be squeezed by the X-direction tooth block 27. The X-direction latch 28 will be squeezed by the X-direction tooth block 27 and deflect with its connection point with the X-direction moving block 22 as the fulcrum, and this end will move upward until the X-direction latch 28 disengages from the X-direction tooth block 27. When the X-direction latch 28 continues to move, the squeezing force from the previous X-direction tooth block 27 on the X-direction latch 28 disappears, and the X-direction latch 28 returns to its initial state under the action of the springback of the torsion spring. The above movement trajectory of the X-direction latch 28 will cycle with the movement of the X-direction moving block 22;

[0082] 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, it will drive the Y-direction moving block 32 to move inside the Y-direction moving slot 31 towards the turning point of the L-shaped fixed mounting bracket 12 or away from the turning point of the L-shaped fixed mounting bracket 12;

[0083] When the Y-direction moving block 32 moves inside the Y-direction moving groove 31 towards the turning point of the L-shaped fixed mounting bracket 12, the movement of the Y-direction moving block 32 will compress the Y-direction traction spring 36 and stretch the Y-direction positioning spring 35. In this movement state, the Y-direction scale pointer 33 provided on the Y-direction moving block 32 indicates a negative value;

[0084] When the Y-direction moving block 32 moves inside the Y-direction moving groove 31 away from the turning point of the L-shaped fixed mounting bracket 12, the movement of the Y-direction moving block 32 will stretch the Y-direction traction spring 36 and compress the Y-direction positioning spring 35. In this movement state, the Y-direction scale pointer 33 provided on the Y-direction moving block 32 indicates a positive value;

[0085] It should be noted that during the movement of the Y-direction moving block 32, the Y-direction clamping rod 38 rotationally connected inside it will move synchronously. Since the Y-direction tooth blocks 37 are fixedly connected at equal intervals on the L-shaped fixed mounting bracket 12, and a disc 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 drive the Y-direction clamping rod 38 to move synchronously. During the movement of the Y-direction clamping rod 38, it will continuously contact the Y-direction tooth blocks 37. Since the Y-direction clamping rod 38 is composed of two symmetrically arranged inclined short rods and a long rod arranged between them, during the movement of the Y-direction clamping rod 38, the inclined short rod at one end of the moving direction of the Y-direction clamping rod 38 will contact 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 deflect with its connection point with the Y-direction moving block 32 as the fulcrum, and this end moves upward until the Y-direction clamping rod 38 disengages from 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 returns to its initial state under the rebound effect of the disc spring. The above movement trajectory of the Y-direction clamping rod 38 will repeat with the movement of the Y-direction moving block 32;

[0086] It should be noted that since the fixed rod 51 is set as a telescopic structure, when the displacement change reaction platform 52 has a displacement 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;

[0087] Since the working application scenarios of this work are mostly construction sites and the environment is relatively messy, when using sensors for monitoring in actual use, it is easily affected by the external environment, resulting in errors in the monitoring data. Through the settings of the X-direction clamping rod 28, X-direction gear block 27, Y-direction clamping rod 38, and Y-direction gear block 37, when the seismic isolation bearing body 11 generates displacement in the X-axis direction or Y-axis direction, the cooperation of the X-direction clamping rod 28, X-direction gear block 27, Y-direction clamping rod 38, and Y-direction gear block 37 will restrict the positions of the X-direction moving block 22 and Y-direction moving block 32 in the reverse direction, avoiding the influence of other objects on the X-direction moving block 22 and Y-direction moving block 32 during actual use. At the same time, since a torsion spring is provided between the X-direction clamping rod 28 and the X-direction moving block 22 and they are rotatably connected, and a disc spring is provided between the Y-direction clamping rod 38 and the Y-direction moving block 32 and they are rotatably connected, when the displacement of the seismic isolation bearing body 11 changes, due to the large mass of the building stacked on the seismic isolation bearing body 11, the cooperation of the X-direction clamping rod 28, X-direction gear block 27, Y-direction clamping rod 38, and Y-direction gear block 37 will not affect the displacement data of the seismic isolation bearing body 11, thus ensuring the accuracy of the displacement data monitoring of the seismic isolation bearing body 11;

[0088] 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 moves in the Z-axis direction along with the seismic isolation bearing body 11, at this time, it will drive the positioning ring 43 to move upward or downward along the guide rail 42 on the Z-direction positioning rod 41 through the fixed rod 51;

[0089] During the above process, the Z-direction scale pointers 44 provided on the upper and lower surfaces of the positioning ring 43 will move accordingly, and then cooperate with the scales provided on the Z-direction positioning rod 41. The staff can quickly obtain the displacement data of the seismic isolation bearing in the Z-axis direction through the data indicated by the Z-direction scale pointers 44;

[0090] During the movement of the positioning ring 43, the link 45 rotatably connected to both ends of the positioning ring 43 will move accordingly. And since the link 46 is rotatably connected to the end of the link 45 far from the positioning ring 43, and the link 46 is rotatably connected to the Z-direction positioning rod 41 at the end far from the link 45, the movement of the positioning ring 43 will drive the link 45 and the link 46 to move synchronously, stretching or contracting in the Z-axis direction. At this time, the connecting spring 47 provided between the link 45 and the link 46 will stretch or contract accordingly;

[0091] Through the settings of the first connecting rod 45, the second connecting rod 46 and the connecting spring 47, when the displacement of the isolation bearing body 11 occurs in the Z-axis direction, the movement of the positioning ring 43 on the Z-direction positioning rod 41 is jointly restricted by the first connecting rod 45, the second connecting rod 46 and the connecting spring 47, maintaining the balance of the positioning ring 43 during the movement and avoiding the situation of skew jamming during the movement of the positioning ring 43, thereby ensuring the accuracy of the positioning ring 43 and the Z-direction scale pointer 44 indicating the Z-axis displacement of the isolation bearing;

[0092] After the displacement monitoring of the isolation bearing body 11 is completed, the staff can disassemble the metal gasket 13 and the mounting gasket 54 from the isolation bearing body 11. At this time, without the traction at the upper and lower ends of the isolation bearing body 11, the displacement change reaction platform 52 will return to its initial state under the action 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 rebounding. 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, when the X-direction scale pointer 23, the Y-direction scale pointer 33 and the Z-direction scale pointer 44 do not indicate the positions of X0, Y0, Z0 after recovery, only 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 need to be replaced at this time.

[0093] Through the settings of the X-direction displacement monitoring component, the Y-direction displacement monitoring component and the Z-direction displacement monitoring component, the staff can quickly know the displacement status of the isolation bearing body 11 during actual use. Compared with the traditional multi-sensor settings, this tooling can avoid the problem of easy damage during the actual construction site environment use, facilitating the use while reducing the cost of monitoring the displacement data of the isolation bearing body 11;

[0094] Through the detachable settings of the metal gasket 13 and the mounting gasket 54 and the telescopic settings of the self-locking telescopic rod 53, this tooling can be reused during actual use and installed on the isolation bearing bodies 11 of different sizes, thereby reducing the demand for corresponding displacement measurement tooling for the isolation bearing bodies 11 of different sizes and reducing the use cost.
