Description

Technical Field

[0001] This utility model relates to the field of bridge or building engineering technology, and specifically to a structural support with multi-performance index monitoring. Background Technology

[0002] Supports located between structures serve two main purposes: transferring loads and accommodating structural deformation and rotation. Current support monitoring primarily focuses on single-data monitoring of forces, rather than simultaneously monitoring multiple performance indicators (such as displacement and rotation). This makes it difficult to determine whether the support is functioning properly, resulting in insufficient functionality. Therefore, this paper proposes a structural support system with multi-performance indicator monitoring capabilities to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a structural support with multiple performance indicators that can simultaneously monitor the displacement and rotation angle of the support in real time, which is more conducive to determining whether the support is in normal working condition and ensuring the safety of the bridge.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A structural support with multiple performance index monitoring includes a support body, which includes an upper support plate, a lower support plate, and a support core located between the upper and lower support plates. The support body is characterized in that an inclination sensor is provided on one side of the upper support plate, and a displacement sensor is also provided for monitoring the sliding displacement between the upper support plate and the support core.

[0006] In this scheme, the tilt sensor on the upper bearing plate can monitor the rotational deviation of the bearing body, and the displacement sensor can monitor the displacement data of the bearing body in the horizontal relative sliding direction between the lower bearing plate and the bearing core in real time. This allows for real-time multi-indicator monitoring of the bearing's displacement and rotation, which is more conducive to determining whether the bearing is in normal working condition and ensuring the safety of the bridge.

[0007] Optionally, a force-measuring elastic body is provided inside the pelvic cavity and located on the bottom surface of the support core. A pressure sensor is provided on the side wall of the pelvic cavity, and the sensing end of the pressure sensor is in direct or indirect close contact with the side wall of the force-measuring elastic body.

[0008] Optionally, the pelvic sidewall has a through hole that communicates with the pelvic cavity, and the sensing end of the pressure sensor passes through the through hole and makes close contact with the sidewall of the force-measuring elastomer.

[0009] Optionally, the pressure sensors are arranged in a cross shape around the pelvic sidewall.

[0010] Optionally, a protective cover is provided on the pelvic sidewall, located outside the pressure sensor, and the protective cover is connected to the pelvic sidewall by screws.

[0011] Optionally, the tilt sensor is connected to a first fixing plate, one end of which is connected to a first mounting plate, and the first mounting plate is fixed to the side of the upper base plate by bolts.

[0012] Optionally, the displacement sensor is connected to a second fixing plate, and a second mounting plate is connected to one side of the second fixing plate. The second mounting plate is fixed to the side of the upper base plate by bolts, and a triangular reinforcing plate is provided between the second fixing plate and the second mounting plate.

[0013] Optionally, the displacement sensor is a pull-rope displacement sensor, with one end of the pull rope connected to the sensor head and the other end connected to the support core. The pull rope is horizontally set and parallel to the relative sliding direction of the support core and the upper plate.

[0014] Optionally, a fixing frame is provided on the side wall of the support core, and the fixing frame is connected to the side wall of the support core by bolts.

[0015] Optionally, the bottom surface of the upper seat plate is bolted with a stop block, which is located on both sides of the support core and the upper seat plate in the relative sliding direction.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, the tilt sensor on the upper seat plate can monitor the rotation angle deviation of the support body, and the displacement sensor can monitor the displacement data of the support body in the horizontal relative sliding direction between the lower seat plate and the support core in real time. This allows for real-time multi-indicator monitoring of the displacement and rotation angle of the support, which is more conducive to determining whether the support is in normal working condition and ensuring the safety of the bridge.

[0025] Example

[0026] A structural support with multiple performance index monitoring includes a support body, which includes an upper support plate 1, a lower support plate 2, and a support core 3 located between the upper support plate 1 and the lower support plate 2. An inclination sensor 4 is provided on one side of the upper support plate 1, and a displacement sensor 5 is also included for monitoring the sliding displacement between the upper support plate 1 and the support core 3.

[0027] In this embodiment, as Figure 1 As shown, the bearing body adopts the existing spherical steel bearing, and the bearing core 3 is the rotating body in the spherical steel bearing. The bearing core 3 can slide relative to the upper bearing plate 1. The tilt sensor 4 is installed on the left side of the upper bearing plate 1, and the displacement sensor 5 is installed on the upper side of the upper bearing plate 1. The tilt sensor 4 adopts the model HWT605-232. The tilt sensor 4 can monitor the rotation angle deviation of the bearing body, and the displacement sensor 5 can monitor the displacement data of the bearing body in the horizontal relative sliding direction between the lower bearing plate 2 and the bearing core 3 in real time. In this way, the displacement and rotation angle of the bearing can be monitored in real time, which is more conducive to judging whether the bearing is in a normal working state and ensuring the safety of the bridge.

[0028] Furthermore, a force-measuring elastic body 12 is provided inside the pelvic cavity and located on the bottom surface of the support core 3. A pressure sensor 6 is provided on the side wall 14 of the pelvic cavity, and the sensing end of the pressure sensor 6 is in close contact with the side wall of the force-measuring elastic body 12.

[0029] Specifically, the signal line of the pressure sensor 6 is connected to the external monitoring unit. The external monitoring unit uses existing technology for data monitoring. During monitoring, it utilizes the isotropic nature of the force-measuring elastomer 12 under pressure in the pelvic cavity, the uniform pressure in all parts of the cavity, and the principle that the positive pressure is basically the same as the pressure exerted by the force-measuring elastomer 12 on the bottom pelvic side (the force-measuring elastomer 12 is a solid elastic material that has near-fluid properties and incompressibility under a certain pressure state. When subjected to compressive stress from the upper structure, the force-measuring elastomer 12 can transmit the compressive stress in all directions without changing its magnitude). The pressure sensor 6 senses the change in compressive stress of the force-measuring elastomer 12 to achieve real-time monitoring of the vertical pressure on the support.

[0030] Furthermore, the pelvic sidewall 14 has a through hole communicating with the pelvic cavity, and the sensing end of the pressure sensor 6 passes through the through hole and makes close contact with the sidewall of the force-measuring elastic body 12. Specifically, in order to facilitate the installation of the pressure sensor 6, the inner wall of the through hole is provided with an internal thread, which is adapted to the external thread on the pressure sensor 6, so that the pressure sensor 6 can be quickly installed and removed.

[0031] Furthermore, the pressure sensors 6 are arranged in a cross shape around the pelvic sidewall 14. Specifically, the pressure sensors are arranged in a cross shape around the pelvic sidewall 14, which allows for monitoring of vertical pressure from multiple directions.

[0032] Furthermore, a protective cover 13 is provided on the pelvic sidewall 14, located outside the pressure sensor 6, and the protective cover 13 is connected to the pelvic sidewall 14 by screws. Specifically, the protective cover 13 is detachably installed on the pelvic sidewall 14 by screws, and the protective cover 13 can protect the pressure sensor 6 and prevent foreign objects from entering.

[0033] Furthermore, the tilt sensor 4 is connected to a first fixing plate 10, and one end of the first fixing plate 10 is connected to a first mounting plate 11. The first mounting plate 11 is fixed to the side of the upper base plate 1 by bolts.

[0034] Specifically, the first fixing plate 10 is located on the outside of the upper base plate 1 and is an extension, providing more installation space when installing the tilt sensor 4.

[0035] Furthermore, the displacement sensor 5 is connected to a second fixing plate 15, and a second mounting plate 16 is connected to one side of the second fixing plate 15. The second mounting plate 16 is fixed to the side of the upper base plate 1 by bolts, and a triangular reinforcing plate 17 is provided between the second fixing plate 15 and the second mounting plate 16.

[0036] Specifically, the second fixing plate 15 and the second mounting plate 16 form a fixing structure for fixing the displacement sensor 5, making the installation of the displacement sensor 5 more secure. At the same time, the second fixing plate 15 is located on the outside of the upper base plate 1, providing more operating space for the installation of the displacement sensor 5.

[0037] Furthermore, the displacement sensor 5 is a pull rope 9 displacement sensor 5. One end of the pull rope 9 of the pull rope 9 displacement sensor is connected to the sensor head, and the other end is connected to the support core 3. The pull rope 9 is set horizontally and is parallel to the relative sliding direction of the support core 3 and the upper seat plate 1.

[0038] Specifically, such as Figure 3 As shown, the displacement sensor 5 is model MPS-S pull rope 9 displacement sensor 5. One end of the pull rope 9 of the displacement sensor is connected to the sensor head, and the other end is connected to the side wall of the support core 3 or the lower base plate 2. The pull rope 9 is in a horizontal state, and its length direction is parallel to the relative sliding direction between the upper base plate 1 and the support core 3. It is used to detect the horizontal displacement of the support body. If the pull rope 9 is vertically connected to the lower base plate 2, it can monitor the vertical displacement of the support body. It can be set according to the actual monitoring requirements.

[0039] Furthermore, a fixing frame 7 is provided on the side wall of the support core 3, and the fixing frame 7 is connected to the side wall of the support core 3 by bolts.

[0040] Furthermore, such as Figure 2 As shown, the bottom surface of the upper base plate 1 is bolted with a stop block 8, which is located on both sides of the support core 3 and the upper base plate 1 in the direction of relative sliding. Specifically, the stop block 8 is detachably connected to the bottom surface of the upper base by bolts and is located inside the displacement sensor 5. The two stop blocks 8 can form a guide channel, and the upper base plate 1 and the support core 3 slide relative to each other along the direction of the guide channel.

Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
