[0001] The invention relates to the technical field of bridge monitoring, and in particular to a viaduct function monitoring component and method. Background Art

[0002] Viaduct monitoring, also known as bridge structure health monitoring, is a technology that monitors the status of bridge structures in real time. Its purpose is to ensure the safety and normal operation of the bridge. Viaduct pier monitoring refers to real-time or regular monitoring of the structural status of viaduct piers. Among them, viaduct pier visual monitoring technology is one of the commonly used monitoring methods. Its principle is mainly to use a camera to capture images of the pier surface, and then use image processing and analysis technology to identify and evaluate the health status of the pier, such as cracks, displacement, erosion and other damage that may affect the safety of the bridge, in order to evaluate its safety and stability.

[0003] Some viaduct piers are double-column piers, which are usually composed of two symmetrically distributed supporting columns connected by cross beams to form a whole, so as to improve the stability and bearing capacity of the viaduct structure support.

[0028] An elevated bridge function monitoring component disclosed in the present invention connects a first movable component 110 and a second movable component 120 so that the first movable component 110 and the second movable component 120 can move in the height direction of the entire double-column pier, and then monitors the pier through a first monitor 220. Compared with the prior art, an avoidance channel 210 is formed by the first movable component 110, the second movable component 120 and the connecting component 130, so that the support column beam can be prevented from hindering the vertical movement of the device, thereby improving the efficiency of the device in monitoring the entire double-column pier. In addition, the first movable component 110 and the second movable component 120 of the device are both provided with a first monitor 220, which can simultaneously monitor the two support columns of the entire double-column pier, and the monitoring efficiency is higher than that of the traditional single support column monitoring.

[0029] Combination Figure 1-5 As shown, in this embodiment, the first movable component 110 and the second movable component 120 both include a movable shell 510 arranged on the opposite side of the support column, a movable cavity 520 is provided in the middle of the movable shell 510, and a connecting channel 530 connected to the movable cavity 520 is opened on the outer wall of the movable shell 510 on one side of the support column, and a driving wheel 540 for moving along the height direction of the support column is provided at the outer wall of the connecting channel 530, and a double-headed motor 550 is provided in the movable cavity 520, and a driving shaft 560 is provided at the driving end of the double-headed motor 550, and a belt 570 is provided between the driving shaft 560 and the driving wheel 540; extensions 580 are provided on both sides of the movable shell 510, and an installation groove 590 is provided on the outer wall of the extension part 580, and the connecting component 130 includes a connecting rod 230 arranged in the installation groove 590, and a first positioning member 240 for pushing the movable shell 510 close to the support column is provided at the connecting rod 230.

[0030] Through the above structure, after the first movable component 110 and the second movable component 120 are installed with the connecting component 130, the double-headed motor 550 located in the movable cavity 520 is started, and the double-headed motor 550 will drive the driving shaft 560 to rotate, thereby driving the belt 570 to drive the driving wheel 540 in the connecting channel 530 to rotate, and drive the movable shell 510 to move in the height direction of the support column; before this, when installing the connecting component 130, the staff inserts the connecting rod 230 into the installation groove 590 on the extension part 580, and then pushes the movable shell 510 toward the middle of the connecting rod 230 through the first positioning member 240 to position it, so that the driving wheel 540 is tightly fitted with the outer wall of the support column, ensuring the stability of the movement of the first movable component 110 and the second movable component 120, and the staff can also adjust the fixed position of the first movable component 110 and the second movable component 120 according to the different spacings between the support columns of the double-column pier, thereby improving the scope of application of the device.

[0031] Combination Figure 2-8 As shown, in this embodiment, a fixing frame 250 is slidably provided at the outer wall of the connecting rod 230, and a second positioning member 410 is provided on both sides of the fixing frame 250 on the outer wall of the connecting rod 230, and an adjustment channel 420 is provided at the fixing frame 250, and an adjustment block 430 that is slidably provided in the adjustment channel 420 and penetrates into the avoidance channel 210 is provided, and a second monitor 810 for monitoring the inner side of the support column is provided at the outer wall of the adjustment block 430; the upper and lower ends of the outer wall of the adjustment block 430 are fixedly connected to the guide block 440, and the guide block 4 A pressing portion 710 is provided on the outer wall of 40, and a guide hole 720 is formed through the outer wall of the pressing portion 710 along the sliding direction of the adjusting block 430. A guide column 730 is provided on the outer wall of the fixing frame 250 and is inserted into the guide hole 720. An adjusting spring 740 is sleeved on the outer wall of the guide column 730 for pushing the guide block 440 to penetrate into the bottom of the beam between the supporting columns; a threaded member 750 is threadedly connected to the outer wall of the guide column 730 at one end of the guide block 440, and the threaded member 750 is used to adjust the sliding distance of the guide block 440.

[0032] Through the above structure, the staff fixes the fixing frame 250 to one side of the inner side of the support column through the second positioning member 410, and the adjusting block 430 will slide in the adjusting channel 420, and the partial area of ​​the adjusting block 430 provided with the second monitor 810 will be pushed into the bottom of the crossbeam of the support column, so as to monitor the inner side of the support column and improve the monitoring quality; at the same time, when the first moving component 110 and the second moving component 120 move to the crossbeam position, the guide block 440 on the adjusting block 430 will contact the crossbeam, thereby squeezing the adjusting block 430 to retract into the adjusting channel 420, avoiding the crossbeam, forming A channel for the beam to pass through. When the adjustment block 430 slides out of the beam area, the adjustment spring 740 on the guide column 730 will push the pressing part 710 to move, so that the adjustment block 430 extends, ensuring that the second monitor 810 goes deep into the inner side of the support column for monitoring again, which not only avoids the obstruction of the movement of the device caused by the beam, but also ensures that multiple sides of the support column are monitored; the staff rotates the threaded part 750 on the guide column 730 to limit the guide block 440, thereby adjusting the sliding distance of the adjustment block 430 to adapt to beams of different sizes and improve the application range of the device.

[0033] Combination Figure 3-6 As shown, in this embodiment, an adjusting rod 310 is provided on the inner side of the outer wall of the adjusting block 430, and a plurality of third monitors 320 are equidistantly distributed along the axial direction on the outer wall of the adjusting rod 310, and the monitoring direction of the third monitor 320 is facing upward; the adjusting rod 310 includes a telescopic support rod 610 provided on the inner side of the outer wall of the adjusting block 430 and a fixed main rod 620 slidably connected to the telescopic support rod 610, a fixing seat 630 is provided at the bottom of the third monitor 320, and a fastening bolt 640 is provided at the fixing seat 630, and the fastening bolt 640 is used to fix the fixing seat 630 with the telescopic support rod 610 and the fixed main rod 620.

[0034] Through the above structure, after the staff has installed the fixing frame 250, they install the adjusting rod 310 on the adjusting block 430, and install multiple third monitors 320 with the monitoring direction facing upward on the adjusting rod 310 according to the monitoring requirements. When the device moves to the bottom of the beam, the third monitor 320 will monitor the bottom of the beam. At the same time, when installing the adjusting rod 310, the telescopic support rod 610 and the fixed main rod 620 can be used to adapt to support columns with different spacings, and the fixing seat 630 can be installed on the telescopic support rod 610 and the fixed main rod 620 by tightening the bolts 640, which is convenient for the staff to install.

[0035] Combination Figure 4-9As shown, in this embodiment, a through cavity 910 is opened through the outer wall of the adjustment block 430, a speed gear set 920 is arranged in the through cavity 910, a connecting portion 930 is connected to the speed gear set 920 at the end of the telescopic support rod 610, and a rotating disk 940 is arranged at the opposite end of the connecting portion 930 of the speed gear set 920, a first cylinder 820 is arranged on the outer wall of the fixing frame 250, a second cylinder 830 is arranged on the outer wall of the rotating disk 940, a driving crank 840 is arranged between the first cylinder 820 and the second cylinder 830, and the driving crank 840 includes a first rod body 950 rotatably connected to the outer wall of the first cylinder 820 and a second rod body 960 rotatably connected to the outer wall of the second cylinder 830, an adaptation cavity 970 for sliding of the second rod body 960 is opened on the outer wall of the first rod body 950, and an adaptation spring 980 is arranged in the adaptation cavity 970.

[0036] Through the above structure, when the guide block 440 contacts the cross beam and drives the adjustment block 430 to retract, the driving crank 840 will drive the rotating disk 940 to rotate. After the rotating disk 940 rotates, the connecting part 930 is driven to rotate 90 degrees through the speed change gear set 920, so that the telescopic support rod 610 and the fixed main rod 620 drive the third monitor 320 to rotate 90 degrees. The monitoring direction of the third monitor 320 will be toward the side of the cross beam, so that when the adjustment block 430 is retracted, the multiple third monitors 320 on the adjustment rod 310 will monitor the side of the cross beam. When the adjustment block 430 slides out of the range of the cross beam and extends, the driving crank 840 drives the rotating disk 940 to rotate again. Similarly, the third monitor 320 rotates 90 degrees again to monitor the top of the cross beam, thereby realizing rapid observation of multiple sides of the cross beam. At the same time, the second rod body 960 is inside the first rod body 950 When the adaptation cavity 970 slides and drives the crank 840 to retract, the adaptation spring 980 will support the first rod body 950 and the second rod body 960, so that the rotating disk 940 can rotate 180 degrees normally. When the rotating disk 940 has completed its rotation, the second rod body 960 will squeeze the adaptation spring 980, thereby penetrating into the adaptation cavity 970. When the adjustment block 430 is extended, the adaptation spring 980 acts in the same way, so that without affecting the normal retraction and extension of the adjustment block 430, the rotation of the rotating disk 940 can be achieved by retracting the adjustment block 430 over a short distance, thereby improving the applicability of the device to beams of different bottom sizes. Moreover, when the device slides down after measurement, the adjustment block 430 will retract and extend again, and the third monitor 320 will rotate 180 degrees, so that after the third monitor 320 completes its measurement, the monitoring head is still facing upward, which is convenient for the next monitoring of the device.

[0037] In addition, this embodiment also provides a viaduct function monitoring method, which includes any of the above-mentioned viaduct function monitoring components and includes the following steps: S1: The staff installs the first moving assembly 110 and the second moving assembly 120 on opposite sides of two supporting columns respectively, and connects them to each other through the connecting assembly 130; S2: Start the first moving assembly 110 and the second moving assembly 120 to move in the height direction of the two support columns, and the first monitor 220 will monitor the outer side surfaces of the two support columns; S3: The adjustment block 430 in the movable shell 510 pushes the second monitor 810 into the middle of the avoidance channel 210 and monitors the inner side of the support column; S4: The guide block 440 will be squeezed with the support column beam, thereby guiding the adjustment block 430 to extend and retract, and drive the second monitor 810 to bypass the support column beam; S5: When the adjusting block 430 is extended or retracted, the adjusting rod 310 is driven to rotate by driving the crank 840, and the orientation of the third monitor 320 is changed so that it can perform multi-faceted detection on the support column in the horizontal direction.

[0038] Through the above structure, when workers measure the double-column bridge pier, they can avoid being blocked by the beam, and by telescopically driving the third monitor 320 to flip multiple times, the beam can be monitored from multiple sides.
