Description

Technical Field

[0001] The invention relates to the technical field of detection devices, in particular to a wave height measuring device for a corrugated beam guardrail. Background Art

[0002] Corrugated beam guardrails are a type of safety and protection structure commonly used in transportation facilities such as roads and railways. Their primary function is to reduce injuries and property damage in traffic accidents. Typically composed of corrugated steel plates and a supporting structure, the corrugated design of a corrugated beam guardrail effectively disperses impact forces, increasing its stability and strength, resulting in high impact resistance and protective properties. The wave height (the height of the corrugated cross-section) of a corrugated beam guardrail directly affects its impact resistance and energy absorption. A wave height that is too low can reduce the guardrail's rigidity and lead to excessive deformation; a wave height that is too high can affect the material's ductility and reduce its energy absorption.

[0003] Laser measuring instruments can provide high-precision measurement results and can accurately measure parameters such as the installation position, length, and height of corrugated beam guardrails. Compared with traditional measurement methods, laser measurement is faster and can complete a large range of measurement tasks in a short time, improving work efficiency. Through these functions, laser measuring instruments provide important technical support in the design, construction, and maintenance stages of corrugated beam guardrails, ensuring that the safety and functionality of the guardrails are fully utilized.

[0004] Prior art CN115325901A discloses a corrugated plate measuring tool. The technical proposal discloses that "the present invention discloses a corrugated plate measuring tool, which relates to the field of corrugated plate detection technology, including a corrugated plate and a measuring tool.

The chuck B slides up and down in the docking groove, and the extension end passes through the through hole. The corrugated plate measuring tool is mounted on the top of the corrugated plate through the chuck A, and then the position of the digital depth gauge is positioned by means of the measuring substrate so that the digital depth gauge is located corresponding to the position to be measured on the corrugated plate. The depth of the position is then measured using the digital depth gauge, which can quickly and accurately measure the wave width, beam height, and wave height of the corrugated plate in an accurate and intuitive manner."

[0005] Although the prior art has disclosed a corrugated plate measuring tool, there are still some shortcomings. Specifically, during the actual production operation process, the corrugated plate measuring tool cannot ensure that the measuring tool is always in a horizontal state during the measurement process, resulting in deviations in the measurement results. In addition, during the measurement process, errors in the measurement results caused by metal debris and dust cannot be avoided. Moreover, the measuring tool needs to be measured manually, and errors in the measurement results caused by human factors cannot be avoided. Summary of the Invention

[0037] Working principle of the present invention: The wave height measuring device can realize the quality inspection of the guardrail board in the horizontal state and the vertical state through the horizontal mechanism 3 and the measuring mechanism 4. Before the quality inspection of the guardrail board in the horizontal state after production, the guardrail board is first placed on the horizontal platform, and the motor 302 is driven to rotate the rotating shaft 303, and the telescopic plate 401 rotates under the drive of the rotating shaft 303. When the level measuring instrument 7 detects that the telescopic plate 401 is in the vertical state, the motor 302 stops running, and the motor 202 is driven to rotate the screw rod 205, and the screw rod 205 drives the lifting bracket 201 to move through the screw nut 206. When the visual sensor 8 detects that the guardrail board is located between the two movable plates 406, Motor 2 202 stops running and pushes the guardrail plate between the two movable plates 406. The high-pressure centrifugal fan 6 transports the high-pressure gas to the flat fan nozzle 503 through the pipeline. The flat fan nozzle 503 sprays high-pressure gas to clean the metal debris on the guardrail plate. Motor 403 drives the gear 404 to rotate. The two racks 405 move toward each other driven by the gear 404. The two movable plates 406 move toward each other driven by the rack 405 until the pressure sensor 408 detects that the movable plate 406 is under pressure. Then the motor 403 stops running and the laser ranging sensor 407 detects the distance between the two movable plates 406. This distance is the wave height of the guardrail plate here.

[0038] Before quality inspection of the vertical guardrail panels after production, the guardrail panels to be inspected are fixed on the inspection columns. Before measurement, the control system controls the motor 102 to operate and drive the driving wheel 104 to rotate. The crawler 106 moves driven by the driving wheel 104 and the guide wheel 105, and moves to the side of the guardrail panel to be inspected with the cooperation of the visual sensor 8, ensuring that the wave height measuring device is horizontally docked on one side of the guardrail panel and the guardrail panel is located on the lower side of the two fixed plates 502. The motor 202 operates to drive the screw rod 205 to rotate, and the screw rod 205 drives the lifting bracket 201 to move downward through the screw nut 206. After the visual sensor 8 detects that the guardrail panel is located between the two fixed plates 502, the motor 202 stops running, and the control system controls the high-pressure centrifugal fan 6 to operate. The high-pressure centrifugal fan 6 transports the high-pressure gas to the flat fan nozzle 503 through the pipeline. The flat fan nozzle 503 sprays high-pressure gas to clean the metal debris on the guardrail plate to ensure that there is no metal debris on the guardrail plate at the measuring position to affect the measurement results. After the visual sensor 8 detects that there is no metal debris on the guardrail plate, the high-pressure centrifugal fan 6 stops running, and the control system controls the motor 102 to drive the crawler 106 to move forward. After the visual sensor 8 detects that the cleaned guardrail plate is located between the two movable plates 406, the motor 102 stops running, and the motor four 403 runs to drive the gear 404 to rotate. The two racks 405 move toward each other under the drive of the gear 404, and the two movable plates 406 move toward each other under the drive of the rack 405. Until the pressure sensor 408 detects that the movable plate 406 is under pressure, the motor four 403 stops running, and the laser ranging sensor 407 detects the distance between the two movable plates 406. This distance is the wave height of the guardrail plate here.

[0039] In addition to quality inspection of guardrail panels after production, the wave height measuring device can also inspect guardrail panels installed on the roadside. Before the guardrail panels on the roadside need to be inspected, the motor 102 is driven to drive the measuring device to the side of the guardrail to be inspected, the motor 202 is driven to drive the screw 205 to rotate, and the screw 205 drives the lifting bracket 201 to move downward through the screw nut 206. After the visual sensor 8 detects that the guardrail panel is located between the two fixed plates 502, the motor 202 stops running, and the control system controls the water pump 10 to operate, and the water in the water tank 11 is transported to the adjustable nozzle 505 through the pipe. The adjustable nozzle 505 sprays high-pressure water to clean the dust, sludge, etc. on the guardrail panel. The water pump 10 is turned off, and the high-pressure centrifugal fan 6 is operated. The high-pressure centrifugal fan 6 transports the high-pressure gas through the pipe to the flat fan nozzle 503 to dry the moisture on the guardrail panel to be inspected, ensuring that there is no dust, water stains, etc. on the guardrail panel at the measuring position that affect the measurement results. The level measuring instrument 7 detects Whether the telescopic plate 401 is in a horizontal state, if the telescopic plate 401 is in a tilted state, the motor three 302 runs to drive the rotating shaft 303 to rotate, and the rotating shaft 303 drives the connecting plate 304 to rotate, and the telescopic plate 401 rotates under the drive of the connecting plate 304. After the level measuring instrument 7 detects that the telescopic plate 401 is in a horizontal state, the motor three 302 stops running, the cylinder 402 runs to drive the push rod to move, and the push rod drives the telescopic plate 401 to move. When the visual sensor 8 detects that the guardrail plate is located in the middle position of the two movable plates 406, the cylinder 402 stops running, and the motor four 403 runs to drive the gear 404 to rotate. The two racks 405 move toward each other under the drive of the gear 404, and the two movable plates 406 move toward each other under the drive of the rack 405. Until the pressure sensor 408 detects that the movable plate 406 is under pressure, the motor four 403 stops running, and the laser ranging sensor 407 detects the distance between the two movable plates 406. This distance is the wave height of the guardrail plate at this location.

[0040] After a measurement is completed, motor four 403 runs in the reverse direction, and the output shaft of motor four 403 drives gear 404 to rotate in the reverse direction. The two racks 405 move in the reverse direction driven by gear 404, and motor two 202 runs in the reverse direction to drive the screw rod 205 to rotate. The lifting bracket 201 moves upward driven by the screw nut 206. After the visual sensor 8 detects that the fixed plate 502 and the movable plate 406 move to the top of the guardrail, motor two 202 stops running, and motor one 102 runs to drive the wave height measuring device to move forward to detect the wave height of the next guardrail. The actual wave height of this section of guardrail is obtained by taking the average value of multiple measurements.
