A smart force-measuring support and a method for quick sensor replacement

Abstract

This application relates to an intelligent force-measuring support and a method for quickly replacing its sensor. The support includes: a sensor pad with a receiving groove; a support body disposed within the receiving groove and used for connection to a main beam; a force sensor disposed at the bottom of the receiving groove for monitoring the force on the support body; and a replacement pad disposed at the bottom of the sensor pad. When the support body is embedded in the receiving groove and in contact with the force sensor, the height of the support body submerged in the receiving groove is less than the thickness of the replacement pad. When the force sensor needs to be replaced, this application only requires supporting the main beam to relieve the pressure on the replacement pad, or lifting the main beam 1-2 mm to separate the sensor pad from the replacement pad, and then pulling out the replacement pad. Afterward, the sensor pad can be completely detached from the support body, allowing the sensor pad to be pulled out from the bottom of the support body to replace the sensor. This enables rapid sensor replacement without replacing the support body, reducing replacement difficulty and costs.

Description

Technical Field

[0001] This application relates to the technical field of bridge bearings, and in particular to an intelligent force-measuring bearing and a method for quickly replacing its sensors. Background Technology

[0002] Currently, seismic isolation bearings are widely used in the bridge field. Among them, friction pendulum seismic isolation bearings have been widely used in actual bridge projects in many countries around the world due to their significant seismic isolation effect, large load-bearing capacity, and relatively mature technology.

[0003] In related technologies, force-measuring supports are supports equipped with force-measuring elements, which can monitor the force on the support. Most of them use force sensors and other methods to monitor the force on the support.

[0004] However, when the force measuring element inside the bearing is damaged, it is difficult to replace it with a new one. Usually, the entire force measuring bearing is replaced. However, the conventional method of replacing the bearing requires lifting the main beam to a very high height, which will affect traffic and the original structure of the bridge. It is costly, time-consuming and labor-intensive. Summary of the Invention

[0005] This application provides an intelligent force-measuring support and a method for quickly replacing its sensor, in order to solve the problem that the sensor of the force-measuring support is difficult to replace in related technologies.

[0006] On the one hand, this application provides an intelligent force-measuring support, the technical solution of which is:

[0007] A smart force-measuring support, comprising:

[0008] A sensor pad with a receiving groove;

[0009] The main body of the support is located in the receiving groove and is used to connect with the main beam;

[0010] A force sensor located at the bottom of the receiving groove is used to monitor the force on the support body.

[0011] The replacement pad is located at the bottom of the sensor pad. When the support body is embedded in the receiving groove and in contact with the force sensor, the height of the support body in the receiving groove is less than the thickness of the replacement pad.

[0012] In some embodiments, it also includes:

[0013] A limiting plate is provided at the bottom of the replacement pad;

[0014] A limiting member is movably connected to the limiting plate, the sensor pad, and the replacement pad, and after the limiting member is movably connected to the limiting plate, the sensor pad, and the replacement pad, it restricts the horizontal movement of the sensor pad and the replacement pad.

[0015] In some embodiments, a limiting groove is formed on the side of the limiting plate, the limiting groove being used for embedding the sensor pad and the replacement pad, and the two ends of the limiting groove are connected.

[0016] In some embodiments, after the sensor pad and the replacement pad are embedded in the limiting groove, they contact the opposite side walls of the limiting groove, and the limiting member is used to restrict the movement of the sensor pad and the replacement pad along the through direction of the limiting groove.

[0017] In some embodiments, a first limiting hole is provided on the side of the limiting plate, a second limiting hole is provided on the sensor pad, and a third limiting hole is provided on the replacement pad. The limiting member includes a limiting block, which is used to embed in the first limiting hole, the second limiting hole, and the third limiting hole to restrict the movement of the sensor pad and the replacement pad.

[0018] In some embodiments, the force sensors are ring-shaped and there are multiple force sensors arranged in a circle around the central axis of the support body.

[0019] In some embodiments, multiple force sensors are arranged in concentric circles with the central axis of the support body as the concentric axis.

[0020] In some embodiments, the force sensor is a resistance strain gauge sensor, a thick-film strain gauge sensor, a thin-film strain gauge sensor, a capacitive sensor, or an amorphous alloy sensor.

[0021] On the other hand, this application also provides a method for quickly replacing the sensor of an intelligent force-measuring support, for replacing the sensor of the intelligent force-measuring support as described above, including:

[0022] Connect the sensor pad to the support body to support the main beam;

[0023] Remove and replace the pad;

[0024] Loosen the connection between the sensor pad and the support body. After the sensor pad falls to the support body and is removed from the receiving groove, pull out the sensor pad.

[0025] After replacing the force sensor, push the sensor pad into the bottom of the support body, and lift the sensor pad until it is embedded in the receiving groove of the support body and in contact with the force sensor.

[0026] Push in the replacement pad, lower the main beam and remove the support for the main beam, so that the sensor pad is supported on the replacement pad, and the sensor replacement is complete.

[0027] In some embodiments, supporting the main beam includes: lifting the main beam until the sensor pad and the replacement pad are separated, and then supporting the main beam.

[0028] The beneficial effects of the technical solution provided in this application include:

[0029] This application provides an intelligent force-measuring support and a method for quickly replacing its sensor. By replacing the pad, sensor pad, receiving groove, and the force sensor at the bottom of the receiving groove, the overall stress on the support body can be monitored through the force sensor. When the force sensor needs to be replaced, simply connect the sensor pad to the support body, apply an upward jacking force to the main beam using a jack or other equipment to support the main beam until the pressure on the replacement pad is relieved, allowing it to be removed. Alternatively, if the replacement pad is difficult to remove, the main beam can be lifted. A height of only 1-2mm is needed to relieve the pressure on the replacement pad and separate the sensor pad from the replacement pad. Then, the replacement pad can be pulled out. After the replacement pad is pulled out, because its thickness is greater than the height of the support body in the receiving groove, after loosening the connection between the sensor pad and the support body, the sensor pad can fall under the action of gravity until it is completely separated from the support body. Thus, the sensor pad can be pulled out from the bottom of the support body to replace the force sensor. The entire replacement process is simple and convenient to operate, and the force sensor can be replaced quickly without disassembling and replacing the support body, which greatly reduces the difficulty and cost.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] This application provides an intelligent force-measuring support and a method for quickly replacing its sensor, which can solve the problem that the sensor of the current force-measuring support is difficult to replace.

[0043] Reference Figure 1-9As shown, an intelligent force-measuring support is provided in an embodiment of this application. The intelligent force-measuring sensor 4 includes a support body 1, a sensor pad 2, a force-measuring component, and a replacement pad 3. The sensor pad 2 is located at the bottom of the support body 1, and a receiving groove 201 is formed on the sensor pad 2 for the support body 1 to be embedded in. The force-measuring component is located at the bottom of the receiving groove 201 and is used to detect the force on the support body 1. The replacement pad 3 is located at the bottom of the sensor pad 2. When the support body 1 is embedded in the receiving groove 201 and in contact with the force-measuring component, the height of the support body 1 sinking into the receiving groove 201 is less than the thickness of the replacement pad 3.

[0044] Reference Figure 1-4 As shown, specifically, the support body 1 is a conventional support, which can be a spherical support, a pot support, a friction pendulum support, etc. In this embodiment, a friction pendulum support is used as an example. It includes an upper support plate 101 and a lower support plate 102 that are arranged at relatively intervals, and a middle support plate 103 disposed between the upper support plate 101 and the lower support plate 102. In this embodiment, the horizontal cross-sections of the upper support plate 101 and the lower support plate 102 are both circular.

[0045] Reference Figure 1-5 As shown, the receiving groove 201 is opened on the upper side of the sensor pad 2. The shape of the receiving groove 201 is designed according to the support body 1. After the support body 1 is embedded in the receiving groove 201, it is restricted to move in the horizontal direction. In this embodiment, the receiving groove 201 is a cylindrical groove, and the lower seat plate 102 of the support body 1 is embedded in it.

[0046] Reference Figure 1-4 As shown, the force measuring assembly includes multiple force sensors 4. The force sensors 4 are installed at the bottom of the receiving groove 201. Correspondingly, a groove is provided at the bottom of the receiving groove 201 for the force sensors 4 to be embedded in. After the force sensors 4 are embedded in the groove, they need to protrude from the groove to perform the force measuring function. A cable hole 202 is provided on the side wall of the receiving groove for the wiring of the force sensors 4 to pass through, so as to facilitate the data transmission of the force sensors 4.

[0047] With the above settings, the overall force on the support body 1 can be monitored by the force sensor 4, and multiple force sensors 4 working together can measure the eccentric force on the support body 1, thereby determining the health status of the support body 1. The sensor pad 2 facilitates the installation of the force sensor 4 and protects the force sensor 4 from damage caused by external environmental interference. The groove in the receiving slot 201 can improve the installation stability of the force sensor 4. At the same time, the receiving slot 201 on the sensor pad 3 can restrict the horizontal movement of the support body 1, thereby improving the installation stability of the support body 1.

[0048] Reference Figure 1-4As shown, the replacement pad 3 is located at the bottom of the sensor pad 2, and the thickness of the replacement pad is set to h1. After the support body 1 is embedded in the receiving groove 201, it presses on the force sensor 4. At this time, the height of the support body 1 sinking into the receiving groove 201 is set to h2. Therefore, it is necessary to satisfy h1>h2. With this setting, after the replacement pad 3 is pulled out from the bottom of the sensor pad 2, the sensor pad 2 can fall under the action of gravity until it is completely separated from the support body 1. Thus, the sensor pad 2 can be pulled out from the bottom of the support body 1 for replacement when the force sensor 4 needs to be replaced.

[0049] With the above setup, when the force sensor 4 needs to be replaced, connect the lower seat plate 102 of the support body 1 to the upper seat plate 101, then connect the sensor pad 2 to the upper seat plate 101 of the support body 1. Use a jack or other equipment to apply a vertical upward jacking force to the main beam and support it until the pressure on the replacement pad 3 is relieved so that it can be pulled out. Then pull out the replacement pad 3. Alternatively, if the replacement pad 3 is difficult to pull out, lift the main beam. At this time, the lifting height of the main beam only needs to reach 1-2mm to relieve the pressure on the replacement pad 4. The pressure of the replacement pad 3 is adjusted, and then the pad 3 is pulled out and replaced. After the replacement pad 3 is pulled out, since its thickness is greater than the height of the support body 1 sinking into the receiving groove 201, the connection between the sensor pad 2 and the upper seat plate 101 is loosened. The sensor pad 2 can fall under the action of gravity until it is completely separated from the support body 1, so that the sensor pad 2 can be pulled out from the bottom of the support body 1 to replace the force sensor 4. The whole replacement process is simple and convenient to operate, and the replacement of the force sensor 4 can be completed quickly, which greatly reduces the sensor replacement cost of the force support.

[0050] Furthermore, it also includes a limiting plate 5 and a limiting component. The limiting plate 5 is located at the bottom of the replacement pad 33, while the limiting component is movably connected to the limiting plate 5, the sensor pad 2, and the replacement pad 3. After the limiting component is movably connected to the limiting plate 5, the sensor pad 2, and the replacement pad 3, it restricts the horizontal movement of the sensor pad 2 and the replacement pad 3. This setting improves the installation stability of the sensor pad 2 and the replacement pad 3, and also improves the installation stability of the support body 1.

[0051] Reference Figure 1-4 As shown, specifically, a limiting groove 501 is provided on the upper side of the limiting plate 5. The limiting groove 501 is provided on the upper side of the limiting plate 5 and is used for the sensor pad 2 and the replacement pad 3 to be embedded. The two ends of the limiting groove 501 are connected, so the limiting member is used to restrict the sensor pad 2 and the replacement pad 3 from moving horizontally within the limiting groove 501.

[0052] Furthermore, when the sensor pad 2 and the replacement pad 3 are embedded in the limiting groove 501, they contact the opposite side walls of the limiting groove 501. The limiting member is used to restrict the movement of the sensor pad 2 and the replacement pad 3 along the through direction of the limiting groove 501. Through the contact between the side wall of the limiting groove 501 and the sensor pad 2 and the replacement pad 3, the movement of the sensor pad 2 and the replacement pad 3 is restricted along the through direction perpendicular to the limiting groove 501. The limiting member only needs to restrict the movement of the sensor pad 2 and the replacement pad 3 in the through direction of the limiting groove 501.

[0053] Reference Figure 4-7 As shown, specifically in this embodiment, the limiting plate 5 is in the shape of a long strip, and the limiting groove 501 extends from one side of the limiting plate 5 to the opposite side. Both ends of the limiting groove 501 penetrate the limiting plate 5. After the replacement pad 3 is embedded in the limiting groove 501, its opposite side walls contact the opposite side walls of the limiting groove 501. After the sensor pad 2 is embedded in the limiting groove 501, its opposite side walls contact the opposite side walls of the limiting groove 501. Thus, the replacement pad 3 is completely embedded in the limiting groove 501, while the upper part of the sensor pad 2 can protrude above the limiting groove 501. In this embodiment, the length and width of the sensor pad 2 and the replacement pad 3 are consistent with the limiting groove 501.

[0054] Reference Figure 1-7 As shown, the limiting component further includes a limiting block 6. A first limiting hole 502 is also provided on the upper side of the limiting plate 5, a second limiting hole 203 is provided on the sensor pad 2, and a third limiting hole 301 is provided on the replacement pad 3. The limiting block 6 is used to embed into the first limiting hole 502, the second limiting hole 203 and the third limiting hole 301 to restrict the sensor pad 2 and the replacement pad 3 from moving along the through direction of the limiting groove 501.

[0055] Reference Figure 1 and Figure 5-7As shown, specifically, the first limiting hole 502 is formed on the upper side of the limiting plate 5 and communicates with the limiting groove 501; the second limiting hole 203 is formed on the side of the sensor pad 2 that contacts the inner wall of the limiting groove 501, and the second limiting hole 203 extends vertically and through the side of the sensor pad 2; the third limiting hole 301 is formed on the side of the replacement pad 3 that contacts the inner wall of the limiting groove 501, and the third limiting hole 301 extends vertically and through the side of the replacement pad 3. The replacement pad 3 and the sensor pad 2 are embedded in the limiting groove 501. When the first limiting hole 502, the second limiting hole 203, and the third limiting hole 301 are all connected, the limiting block 6 is embedded in the first limiting hole 502, the second limiting hole 203, and the third limiting hole 301, which can restrict the movement of the sensor pad 2 and the replacement pad 3 along the through direction of the limiting groove 501 in the horizontal direction. In conjunction with the side wall of the limiting groove 501, it can restrict the movement of the sensor pad 2 and the replacement pad 3 in the entire horizontal direction, thereby improving the stability of the sensor pad 2 and the replacement pad 3 during installation. In this embodiment, the first limiting hole 502, the second limiting hole 203, and the third limiting hole 301 are all designed with an isosceles trapezoidal horizontal cross-section, and when connected, they form an hourglass-shaped hole. The shape of the limiting block 6 is designed accordingly.

[0056] Furthermore, a first limiting hole 502 is opened on each of the opposite sides of the limiting groove 501, a second limiting hole 203 is opened on each of the opposite sides of the sensor pad 2, and a third limiting hole 301 is opened on each of the opposite sides of the replacement pad 3. Correspondingly, two limiting blocks 6 are provided, which are used to be embedded in the two sets of limiting holes respectively, which can improve the fixing effect of the sensor pad 2 and the replacement pad 3.

[0057] Reference Figure 1-4 As shown, the bottom of the limiting plate 5 is further provided with a support pad 7. The support pad 7 has an installation groove for the limiting plate 5 to be inserted into, and when the limiting plate 5 is inserted into the installation groove, the bottom of the limiting groove 501 is flush with the upper surface of the support pad 7.

[0058] During the initial construction of the bearing, the construction portion of the bearing pad 7 is first poured at the bearing location. The limiting plate 5 is then installed on the bearing pad 7 by welding or bolt connection. Then, the remaining portion of the bearing pad 7 is poured to ensure that the upper surface of the bearing pad 7 is flush with the bottom plane of the upper limit groove 501 of the limiting plate 5. After that, the replacement pad 3, sensor pad 2, force sensor 4, and bearing body 1 are installed on the limiting plate 5 in sequence.

[0059] Reference Figure 8As shown, the force sensor 4 is further annular, consisting of an annular sensor body 401 and an annular force-measuring ridge 402. The force-measuring ridge 402 is coaxial with the sensor body 401 and located on one side of the sensor body 401 along its axial direction. During installation, the axis of the force sensor 4 is parallel to the axis of the receiving groove 201, and the force-measuring ridge 402 protrudes from the bottom groove of the receiving groove 201. The annular force sensor 4 experiences uniform force, resulting in more accurate measurements of the force on the support body 1.

[0060] Reference Figure 9 As shown, the force-measuring ridge 402 can be broken in the middle to form several arc-shaped ridges. Each arc-shaped ridge can measure a pressure data, thereby realizing the function of one sensor measuring the force at different positions on the same plane. The force-measuring ridge 402 can be broken into arc-shaped ridges according to the actual force measurement needs, and can be broken into two, three, four or more arc-shaped ridges.

[0061] Multiple force sensors 4 are arranged in a circle around the central axis of the support body 1, or multiple force sensors 4 are arranged in concentric circles with the central axis of the support body 1 as the concentric axis. Different sensor arrangement schemes can be selected as needed. When the latter scheme is selected, the diameters of the multiple force sensors 4 are different, and in each force sensor 4, the force measuring edge 402 can be a whole, or it can be broken to form two, three or more arc edges, which can be selected according to actual needs.

[0062] The force sensor 4 can be a resistance strain gauge sensor, a thick film strain gauge sensor, a thin film strain gauge sensor, a capacitive sensor, or an amorphous alloy sensor. Different types of sensors can be selected as needed.

[0063] The implementation principle of this embodiment is as follows: When it is necessary to replace the force sensor 4, first remove the limiting block 6, connect the upper seat plate 101 and the lower seat plate 102 of the support body 1, and simultaneously connect the sensor pad 2 to the upper seat plate 101. The connection of the upper seat plate 101 and the lower seat plate 102 and the connection of the sensor pad 2 to the upper seat plate 101 are carried out separately. Use a jack to apply an upward pushing force to the main beam and support the main beam until the pressure on the replacement pad 3 is relieved so that it can be pulled out, or the main beam can be lifted to a certain height and then supported. The main beam only needs to be lifted 1-2mm. At this point, the sensor pad 2 and the replacement pad 3 will separate. Then, the replacement pad 3 will be pulled out, and the connection between the sensor pad 2 and the upper seat plate 101 will be loosened. The sensor pad 2 will fall under gravity until it separates from the lower seat plate 102. The sensor pad 2 will be pulled out and a new force sensor 4 will be replaced. Then, the sensor pad 2 and the replacement pad 3 will be reinstalled in their original positions. The jack will be removed, and the connection between the upper seat plate 101 and the lower seat plate 102 will be loosened. This completes the replacement of the force sensor 4.

[0064] On the other hand, this application embodiment also provides a method for quickly replacing the sensor of an intelligent force-measuring support, used to replace the sensor of the intelligent force-measuring support as described above, including the following steps:

[0065] Connect the sensor pad 2 to the support body 1 to support the main beam. Specifically, before doing so, remove the limiting block 6, then connect the upper seat plate 101 and the lower seat plate 102 of the support body 1, and simultaneously connect the sensor pad 2 to the upper seat plate 101. The connection between the upper seat plate 101 and the lower seat plate 102 and the connection between the sensor pad 2 and the upper seat plate 101 are done separately. Then, use a jack to apply an upward pushing force to the main beam and support the main beam until the pressure on the replacement pad 3 is relieved, or lift the main beam until the sensor pad 2 and the replacement pad 3 are separated and then support the main beam. The lifting height of the main beam only needs to reach 1-2mm. At this time, the sensor pad 2 and the replacement pad 3 are separated.

[0066] Pull out the replacement pad 3. Specifically, pull out the replacement pad 3 along the limiting groove 501 of the limiting plate 5. At this time, the sensor pad 2 is connected to the upper seat plate 101 of the support body 1 and will not fall off.

[0067] Loosen the connection between the sensor pad 2 and the support body 1. The sensor pad 2 falls until the support body 1 is separated from the receiving groove 201, and then the sensor pad 2 is pulled out. Specifically, loosen the connection between the sensor pad 2 and the upper seat plate 101. The sensor pad 2 falls under gravity. Since the thickness of the replacement pad 3 is greater than the height of the support body 1 sinking into the receiving groove 201, after loosening the sensor pad 2, the sensor pad 2 falls under gravity until it is completely separated from the support body 1 from the receiving groove 201. Then, the sensor pad 2 is pulled out along the limiting groove 501. At this time, the lower seat plate 102 of the support body 1 will not fall off the connection with the upper seat plate 101.

[0068] After replacing the force sensor 4, push the sensor pad 2 into the bottom of the support body 1, and lift the sensor pad 2 until it is embedded in the receiving groove 201 and in contact with the force sensor 4. Specifically, after pulling out the sensor pad 2, take out the old force sensor 4, replace it with a new force sensor 4, and then push the sensor pad 2 into the bottom of the support body 1 along the limiting groove 501. Lift the sensor pad 2 until it is embedded in the receiving groove 201 on the lower seat plate 102 of the support body 1 and in contact with the force sensor 4.

[0069] Push in the replacement pad 3, remove the support for the main beam, and let the sensor pad 2 rest on the replacement pad 3. The sensor replacement is complete. Specifically, push the replacement pad 3 along the limiting groove 501 under the sensor pad 2, remove the jack to remove the support for the main beam, and let the sensor pad 2 rest on the replacement pad 3. Then install the limiting block 6, and remove the connection between the upper seat plate 101 and the lower seat plate 102 of the support body 1. The replacement of the force sensor 4 is now complete.
