Description

Technical Field

[0001] This utility model relates to the field of bridge inspection technology, specifically to an installation device for a vibration pickup. Background Technology

[0002] Vibration pickups are crucial sensors used to measure the vibration response of structures such as bridges and buildings. In bridge monitoring, vibration pickups are typically installed at locations such as the bottom of beams to collect vibration data. They are widely used to acquire the vibration response of structures under environmental excitations or vehicle loads. By analyzing the vibration signals, the dynamic characteristics of the structure can be assessed, damage status can be identified, and critical data support can be provided for decisions regarding the safe operation and maintenance of the structure. Existing vibration pickup cables are usually simply led out and fixed. In complex outdoor environments, especially in strong winds or rain and snow, the suspended cables are subjected to significant tension. This tension may not only be transmitted to the pickup, affecting the reliability of its connection to the mounting base and causing data acquisition distortion, but may also directly lead to cable fatigue or even breakage, causing signal interruption and severely impacting the accuracy and long-term reliability of bridge data acquisition.

[0003] Existing vibration pickup installation devices make it difficult to fix the vibration pickup cable and detect its stress state, which affects the reliability and accuracy of the vibration pickup's data acquisition from the bridge. This utility model aims to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an installation device for a vibration pickup, which can not only reliably fix the cable but also monitor the cable tension in real time, ensuring the reliability and accuracy of the vibration pickup data acquisition.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an installation device for a vibration pickup includes an upper flange plate connected to the bottom of a beam, a lower flange plate for supporting the vibration pickup, and a middle web plate connected between the upper flange plate and the lower flange plate. A permanent magnet for fixing the vibration pickup is provided on the lower flange plate. A cable-binding mechanism is also provided on the lower flange plate for fixing the cable of the vibration pickup. A through hole is provided on the middle web plate, through which the cable passes sequentially and is connected to a computer. The cable-binding mechanism includes a support base and a clamping assembly provided on the support base. The clamping assembly is used to clamp and detect the tension of the cable. A controller electrically connected to the clamping assembly is provided on the support base. An indicator light is also provided on the lower flange plate, and the indicator light is electrically connected to the controller.

[0006] The support base is provided with a receiving groove. The clamping assembly includes a cable clamp plate that is oscillatingly disposed in the receiving groove, a spring connected at one end to the side of the cable clamp plate, and a pressure sensor that abuts against the other end of the spring. The pressure sensor is fixedly disposed in the receiving groove and is electrically connected to the controller. The cable clamp plate is provided with a plurality of slots for fixing the cable, and the cable is sequentially arranged to pass through a plurality of the slots.

[0007] The support base is provided with an inlet slot and an outlet slot that communicate with the receiving slot, and the edges of the inlet slot and the outlet slot are rounded.

[0008] The cable clip has a connecting post on its side, the spring is sleeved on the outside of the connecting post, and the end of the connecting post is detachably abutted against the pressure sensor.

[0009] The upper flange plate is provided with a second mounting hole and a second permanent magnet. The second permanent magnet is attracted to the bottom of the steel beam, and the second mounting hole is used to fix it to the bottom of the concrete beam.

[0010] Both the upper flange and the middle web are provided with several weight-reducing holes.

[0011] The lower flange plate is provided with a mounting hole, which is used to install different types of vibration pickups.

[0012] A first rib is provided between the upper flange and the middle web, and a second rib is provided between the middle web and the lower flange.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The cable of the vibration pickup is fixed by the clamping component in the cable harness mechanism and the tension of the cable is detected in real time. When the cable tension is too high due to external factors such as wind or rain and snow, the pressure sensor transmits the signal to the controller, triggering the indicator light alarm, indicating that the cable needs to be adjusted or the weather needs to be improved; otherwise, the indicator light shows normal, avoiding the cable tension from being transmitted to the vibration pickup, affecting the connection reliability or causing the cable to break, thereby ensuring the long-term accuracy and reliability of bridge vibration data acquisition.

[0015] (2) The upper flange plate is provided with two permanent magnets and two mounting holes, which are used to be attracted to the bottom of the steel beam or fixed to the bottom of the concrete beam, respectively.

[0025] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] See Figures 1-7An installation device for a vibration pickup 7 includes an upper flange plate 1 connected to the bottom of a beam, a lower flange plate 2 for supporting the vibration pickup 7, and a middle web plate 3 connected between the upper flange plate 1 and the lower flange plate 2. A permanent magnet 21 for fixing the vibration pickup 7 is provided on the lower flange plate 2. A cable harnessing mechanism 6 is also provided on the lower flange plate 2 for fixing the cable 8 of the vibration pickup 7. A through hole 31 is provided on the middle web plate 3. The cable 8 passes through the cable harnessing mechanism 6 and the through hole 31 in sequence and is connected to a computer. The cable harnessing mechanism 6 includes a support base 61 and a clamping assembly 62 provided on the support base 61. The clamping assembly 62 is used to clamp and detect the tension of the cable 8. A controller electrically connected to the clamping assembly 62 is provided on the support base 61. An indicator light 23 is also provided on the lower flange plate 2 and is electrically connected to the controller.

[0027] The support base 61 is provided with a receiving groove 611. The clamping assembly 62 includes a cable clamping plate 621 that is oscillatingly disposed in the receiving groove 611, a spring 622 connected at one end to the side of the cable clamping plate 621, and a pressure sensor 623 that abuts against the other end of the spring 622. The pressure sensor 623 is fixedly disposed in the receiving groove 611 and is electrically connected to the controller. The cable clamping plate 621 is provided with a plurality of slots 6211 for fixing the cable 8. The cable 8 is arranged to pass through a plurality of slots 6211 in sequence. Specifically, the controller is configured to control the indicator light 23 to issue an alarm signal when the pressure value detected by the pressure sensor 623 exceeds a preset threshold.

[0028] The support base 61 is provided with an inlet groove 612 and an outlet groove 613 that are connected to the receiving groove 611. The edges of the inlet groove 612 and the outlet groove 613 are rounded.

[0029] A connecting post 624 is provided on the side of the cable clamp 621. A spring 622 is sleeved on the outside of the connecting post 624. The end of the connecting post 624 is detachably abutted against the pressure sensor 623. That is, the end of the connecting post 624 and the sensing surface of the pressure sensor 623 form a detachable abutting fit. When the connecting post 624 presses against the pressure sensor 623, the pressure sensed by the pressure sensor 623 increases.

[0030] The upper flange plate 1 is provided with mounting holes 21 and permanent magnets 212 respectively. The permanent magnets 212 are attracted to the bottom of the steel beam, and the mounting holes 211 are used to fix it to the bottom of the concrete beam.

[0031] Both the upper flange plate 1 and the middle web plate 3 are provided with several weight-reducing holes 5. Specifically, the several arrayed weight-reducing holes 5 provided on the upper flange plate 1 and the middle web plate 3 effectively reduce the overall weight of the device while ensuring structural strength.

[0032] The lower flange plate 2 is provided with mounting hole 22, which is used to install different types of vibration pickups 7.

[0033] Rib 4a is provided between the upper flange 1 and the middle web 3, and rib 4b is provided between the middle web 3 and the lower flange 2.

[0034] The specific working process of this utility model:

[0035] When the tension on the suspended cable 8 is too high, such as due to strong winds or rain and snow, it not only affects the reliability of the connection between the cable 8 and the vibration pickup 7, but also makes the cable 8 susceptible to damage and breakage, thus affecting the accuracy and reliability of bridge data acquisition. When the tension on the cable 8 is too high, the cable 8 causes the cable clamp 621 to swing against the elastic force of the spring 622, causing the connecting post 624 to contact the pressure sensor 623. If the pressure sensor 623 experiences high pressure, the controller will analyze and process the data and send a command to the indicator light 23, causing the indicator light 23 to light up red, indicating that the vibration pickup 7 does not meet the data acquisition requirements. The cable 8 needs to be lengthened or the weather needs to be improved. If the tension on the cable 8 is low due to the external environment, the tension on the cable clamp 621 is low, and the cable clamp 621 rotates less against the elastic force of the spring 622. The pressure sensor 623 senses that the pressure of the spring 622 is low, and the indicator light 23 lights up green, indicating that the connection between the cable 8 and the vibration pickup 7 is firm and reliable, which is more conducive to the accurate acquisition of bridge data.

[0036] The cable 8 of the vibration pickup 7 is fixed by the clamping component 62 in the cable harness mechanism 6, and the tension of the cable 8 is detected in real time. When the tension of the cable 8 is too high due to external factors such as wind or rain and snow, the pressure sensor 623 transmits the signal to the controller, triggering the indicator light 23 to alarm, indicating that the cable 8 needs to be adjusted or waiting for the weather to improve; otherwise, the indicator light 23 shows normal, which avoids the tension of the cable 8 being transmitted to the vibration pickup 7, affecting the connection reliability or causing the cable 8 to break, thereby ensuring the long-term accuracy and reliability of bridge vibration data acquisition.

[0037] The upper flange plate 1 is provided with a permanent magnet 212 and a mounting hole 211, which are used to be attracted to the bottom of the steel beam or fixed to the bottom of the concrete beam, respectively. The lower flange plate 2 is provided with a permanent magnet 121 and a mounting hole 122 for installing different types of vibration pickups 7, so that the device can adapt to beams of different materials and various vibration pickup 7 models, making the installation device more adaptable.

[0038] Weight reduction holes 5 are provided on the upper flange plate 1 and the middle web plate 3 to effectively reduce the weight of the device. At the same time, rib plate 1 4a and rib plate 2 4b are respectively provided between the upper flange plate 1 and the middle web plate 3 and between the middle web plate 3 and the lower flange plate 2, which enhances the overall structural strength, reduces the load on the installation device, and makes the vibration pickup 7 more stable and reliable to install.
