Description

Technical Field

[0002] Road refers to highways, urban roads and places under the jurisdiction of a unit but where social motor vehicles are allowed to pass, including squares, public parking lots and other places for public passage. Bridges refer to structures built on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. Roads and bridges will undergo settlement and deformation during use. Settlement and deformation refer to the sinking of roads and bridges due to improper selection of roadbed filling materials, unreasonable filling methods, insufficient compaction, and the combined effects of load, water, and temperature. Settlement and deformation will cause roads and bridges to sink and be damaged, resulting in uneven road surfaces and affecting transportation. For this reason, it is necessary to use settlement and deformation detection devices to detect the degree of settlement of roads and bridges.

[0003] Existing road bridge settlement and deformation detection devices are usually fixedly installed inside the roadbed, which is inconvenient to install and inconvenient to maintain after a failure. The road surface needs to be broken for maintenance, which affects traffic and is extremely time-consuming and labor-intensive. At the same time, the detection points are fixed, the detection data is limited, and the detection results cannot form a continuous data chain, which cannot reflect the actual settlement and deformation of the road bridge. Therefore, it is urgent to design a road bridge settlement and deformation detection device. Summary of the invention

[0044] Working principle:

[0045] First, the road bridge settlement deformation detection device is installed, and then the control disc 507 is pressed, and then the control disc 507 moves the inner spline tube 506 to the right, and then the inner spline tube 506 moves the guide slide plug 509 to the right, and then the anti-rotation convex tooth 511 is pulled out from the inside of the limiting tooth groove 510, and then the inner spline tube 506 is released, and then the control disc 507 is rotated, and then the control disc 507 rotates the inner spline tube 506, and then the inner spline tube 506 rotates with the upper limit adjustment rod 502 through the transmission spline rod 505, and then the upper limit adjustment rod 502 rotates with the upper limit adjustment wheel 503, and then the inclination wire 204 is wound around the outside of the upper limit adjustment wheel 503 and released from the outside of the inclination wire wheel 203, and then the inclination wire 204 is wound around the outside of the upper limit adjustment wheel 503 and released from the outside of the inclination wire wheel 203, and then the inclination wire 20 The inclination wheel 203 is driven to rotate, and then the inclination wheel 203 rotates with the flip single rod 202, and then the flip single rod 202 flips with the first distance meter 15, and then the upper limit boundary detected by the first distance meter 15 is retracted to the position where the detection hollow vertical rod 11 is located, which is suitable for narrower roads. According to the above principle, when the control disk 507 is rotated in the opposite direction, the upper limit boundary detected by the first distance meter 15 gradually moves away from the detection hollow vertical rod 11, which is suitable for wider roads, until the upper limit boundary detected by the first distance meter 15 is aligned with one side of the road surface, and then the control disk 507 is released, and then the guide slide plug 509 moves to the left with the limit tooth groove 510 under the action of the elastic force of the pre-compression spring 508, and then the anti-rotation convex tooth 511 is inserted into the limit tooth groove 510, and the guide slide plug 509 is moved to the left with the limit tooth groove 510 ..., and then the anti-rotation convex tooth 511 is inserted into the limit tooth groove 510, and the guide slide plug 509 is moved to the left with the limit tooth groove 510, and then the anti- 9 is locked, thereby fixing the upper limit boundary detected by the first rangefinder 15, and then the compass 33 is driven to rotate, and then the compass 33 is driven to rotate with the brake screw 32, and then the brake screw 32 moves to the left under the action of the threaded cooperation between it and the straightening protrusion 31, and then the end of the brake screw 32 is against the surface of the synchronous rotating disk 214 and stops it, and then the lower limit constraint disk 402 is pressed to the left, and then the lower limit constraint disk 402 moves to the left with the movable bevel gear 407 through the lower limit constraint screw 401, and then the movable bevel gear 407 is meshed with the positioning bevel gear 409, and then the lower limit constraint disk 402 is rotated, and then the lower limit constraint disk 402 passes through the lower limit constraint screw 401, the movable bevel gear 407 and the positioning bevel gear 409. The meshing action drives the adjusting screw 408 to rotate, and then the displacement slider 411 drives the quantitative pressing wheel 215 radially away through the linkage short rod 412 under the action of the threaded cooperation between it and the adjusting screw 408, and then the lower limit boundary detected by the first rangefinder 15 gradually approaches the position of the hollow vertical pole 11 for detection. According to the above principle, the lower limit constraint disk 402 is rotated in the opposite direction, and the quantitative pressing wheel 215 radially approaches, and the lower limit boundary detected by the first rangefinder 15 gradually moves away from the position of the hollow vertical pole 11 for detection, until the lower limit boundary detected by the first rangefinder 15 is aligned with the other side of the road surface, and then the lower limit constraint disk 402 is released, and then the lower limit constraint slide disk 405 drives the lower limit constraint screw 401 to move to the right under the action of the elastic force of the lower limit constraint spring 404.After that, the lower limit constraint screw 401 moves rightward with the movable bevel gear 407, and then the movable bevel gear 407 is separated from the positioning bevel gear 409, and then the compass 33 is driven in the reverse direction, and then the brake screw 32 moves rightward and separates from the synchronous turntable 214, so that the adjustment is completed, and then the road bridge settlement deformation detection device is turned on, and then the processing module 18 controls the drive motor 209 to run, and then the drive motor 209 rotates with the synchronous turntable 214 through the power wheel 210, the transmission belt 211, and the synchronous turntable 212, and then the synchronous turntable 214 rotates with the quantitative pressure wheel 215 through the adjusting screw 408, the displacement slider 411, and the linkage short rod 412, and then the quantitative pressure wheel 215 contacts the inclination wire 204 and applies a downward force to it. The inclination wire 204 is bent downward and released from the outside of the inclination wire wheel 203, and then the inclination wire wheel 203 flips over. Then the inclination wire wheel 203 flips downward with the first rangefinder 15 by flipping the single rod 202. At the same time, the first rangefinder 15 flips with the reset traction wheel 63 by the reset traction column 62. The reset traction wire 64 is wound around the outside of the reset traction wheel 63, and then the open slide 410 is vertically downward. At this time, the quantitative pressure wheel 215 moves downward to the extreme position, and the first rangefinder 15 flips downward to the extreme position. Then the synchronous turntable 214 continues to rotate in a circle with the quantitative pressure wheel 215, and then the reset traction wire 64 is released from the outside of the reset traction wheel 63 under the action of the gravity of the counterweight slider 67 and drives it to rotate, and then reset. The traction wheel 63 rotates with the reset traction column 62, and then the reset traction column 62 rotates with the first distance meter 15 in the opposite direction, and then the quantitative pressure wheel 215 separates from the inclination wire 204. At this time, the first distance meter 15 flips upward to the extreme position, and then the quantitative pressure wheel 215 contacts the inclination wire 204 again and applies pressure to it, and then repeats the above process to make the first distance meter 15 flip up and down. During this process, the first distance meter 15 continuously detects the distance between it and the road surface and transmits the distance data value to the processing module 18. At the same time, the reset traction column 62 rotates with the conductive slide bar 703, and then the pre-tensioning insulating disk 707 applies a thrust to the conductive slide bar 703 under the action of the elastic force of the pre-tensioning spring 706, and then the end of the conductive slide bar 703 abuts against the resistor On the surface of the strip 710, the conductive sliding rod 703 then rotates to change the length of the resistor strip 710 connected to the circuit. Then the processing module 18 calculates the inclination of the first rangefinder 15 according to the length of the resistor strip 710 connected to the circuit. Then the processing module 18 processes the data according to the principle of trigonometric function and records the processed data. The data recorded by the processing module 18 is the horizontal distance and vertical distance between a single detection point and the first rangefinder 15. The horizontal distance reflects the settlement deformation position, and the vertical distance reflects the settlement deformation amount. The first detection data is the reference data. The processing module 18 will record the first detection data. At the same time, the processing module 18 will compare the subsequent detection data with the reference data to obtain the settlement deformation situation.Then, when the road surface sinks and deforms, the vertical distance of the corresponding detection point relative to the first rangefinder 15 changes, and then the processing module 18 sends a settlement alarm to the terminal and displays the horizontal distance between the settlement deformation position and the first rangefinder 15, so that the staff can quickly find the settlement deformation position and implement protective measures. When the road bridge settlement deformation detection device is installed on the bridge deck, the first rangefinder 15 is used to detect the settlement deformation of the bridge deck. At the same time, the second rangefinder 88 naturally droops under the action of its own gravity, and then the second rangefinder 88 detects the distance between it and the ground in real time. When the bridge sinks, the distance detected by the second rangefinder 88 decreases, and then the second rangefinder 88 sends information to the processing module 18, and the processing module 18 sends a settlement alarm to the terminal so that people can take protective measures in time.
