Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and specifically, it is a device for measuring the wave height of corrugated beam guardrails. Background Art

[0002] The corrugated beam guardrail is a safety protection structure commonly used in transportation facilities such as highways and railways. Its main function is to reduce injuries and property losses in traffic accidents. It is usually composed of corrugated steel plates and a support structure. The corrugated design of the corrugated beam guardrail can effectively disperse the impact force, increase its stability and strength, and has high anti-impact and protection performance. The wave height (the height of the corrugated cross-section) of the corrugated beam guardrail directly affects its anti-impact ability and energy absorption effect. If the wave height is too small, the rigidity of the guardrail may be reduced, resulting in excessive deformation; if the wave height is too large, it may affect the ductility of the material and weaken the energy absorption effect.

[0003] Laser measuring instruments can provide highly accurate 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 large-scale 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 functions of the guardrails are fully exerted.

The chuck B slides up and down in the docking groove, and the extension end penetrates through the perforation. For this corrugated plate measuring tool, the measuring tool is installed on the top of the corrugated plate through the chuck A, and then the position of the digital display depth gauge is positioned by the measuring substrate, so that the digital display depth gauge is located corresponding to the position to be measured of the corrugated plate, and then the depth of this position is measured by using the digital display depth gauge, and the wave width, beam height, and wave height of the corrugated plate can be measured quickly and accurately, accurately and intuitively."

[0037] Working principle of the present invention: The wave height measuring device can perform quality inspection on guardrail plates in horizontal and vertical states through the horizontal mechanism 3 and the measuring mechanism 4. Before performing quality inspection on the horizontally placed guardrail plates after production, first place the guardrail plates on the horizontal platform. The motor three 302 operates to drive the rotating shaft 303 to rotate. The telescopic plate 401 rotates under the drive of the rotating shaft 303. When the horizontal measuring instrument 7 detects that the telescopic plate 401 is in a vertical state, the motor three 302 stops operating. The motor two 202 operates to drive the lead screw 205 to rotate. The lead screw 205 drives the lifting bracket 201 to move through the lead screw nut 206. When the vision sensor 8 detects that the guardrail plate is located between the two moving plates 406, the motor two 202 stops operating. Push the guardrail plate into the space between the two moving plates 406. The high-pressure centrifugal fan 6 conveys high-pressure gas through the pipeline to the flat fan-shaped nozzle 503. The flat fan-shaped nozzle 503 sprays high-pressure gas to clean the metal debris on the guardrail plate. The motor four 403 operates to drive the gear 404 to rotate. The two racks 405 move towards each other under the drive of the gear 404. The two moving plates 406 move towards each other under the drive of the racks 405. Until the pressure sensor 408 detects the pressure on the moving plate 406, the motor four 403 stops operating. The laser distance sensor 407 measures the distance between the two moving plates 406, and this distance is the wave height of the guardrail plate at this location.

[0038] Before the quality inspection of the vertically placed guardrail plate after production, the guardrail plate to be tested is fixed on the inspection column. Before measurement, the control system controls the operation of the first motor 102 to drive the driving wheel 104 to rotate. The crawler 106 moves under the drive of the driving wheel 104 and the guide wheel 105, and moves to one side of the guardrail plate to be tested with the cooperation of the visual sensor 8, ensuring that the wave height measuring device is horizontally docked on one side of the guardrail plate, and the guardrail plate is located under the two fixed plates 502. The second motor 202 operates to drive the lead screw 205 to rotate. The lead screw 205 drives the lifting bracket 201 to move downward through the lead screw nut 206. After the visual sensor 8 detects that the guardrail plate is located between the two fixed plates 502, the second motor 202 stops operating. The control system controls the operation of the high-pressure centrifugal fan 6. The high-pressure centrifugal fan 6 conveys high-pressure gas through the pipeline to the flat fan-shaped nozzle 503. The flat fan-shaped nozzle 503 sprays high-pressure gas to clean the metal debris on the guardrail plate, ensuring that there is no metal debris on the guardrail plate at the measurement position that affects the measurement result. After the visual sensor 8 detects that there is no metal debris on the guardrail plate, the high-pressure centrifugal fan 6 stops operating. The control system controls the operation of the first 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 moving plates 406, the first motor 102 stops operating. The fourth motor 403 operates to drive the gear 404 to rotate. The two racks 405 move towards each other under the drive of the gear 404. The two moving plates 406 move towards each other under the drive of the racks 405 until the pressure sensor 408 detects the pressure on the moving plate 406, and then the fourth motor 403 stops operating. The laser distance sensor 407 measures the distance between the two moving plates 406, and this distance is the wave height of the guardrail plate at this position.

[0039] In addition to inspecting the guardrail plates after production, the wave height measuring device can also detect the guardrail plates installed by the roadside. Before detecting the guardrail plates by the roadside, the motor 102 runs to drive the measuring device to move to one side of the guardrail to be detected. The motor 202 runs to drive the lead screw 205 to rotate. The lead screw 205 drives the lifting bracket 201 to move downward through the lead screw nut 206. After the visual sensor 8 detects that the guardrail plate is located between the two fixed plates 502, the motor 202 stops running. The control system controls the water pump 10 to run, and conveys the water in the water tank 11 to the adjustable nozzle 505 through the pipeline. The adjustable nozzle 505 sprays high-pressure water flow to clean the dust, sludge, etc. on the guardrail plate. The water pump 10 is closed, and the high-pressure centrifugal fan 6 runs. The high-pressure centrifugal fan 6 conveys high-pressure gas to the flat fan-shaped nozzle 503 through the pipeline to air-dry the water on the guardrail plate at the detection position, ensuring that there is no dust, water stains, etc. on the guardrail plate at the measurement position that affect the measurement result. The level gauge 7 detects whether the telescopic plate 401 is in a horizontal state. If the telescopic plate 401 is in an inclined state, the motor 302 runs to drive the rotating shaft 303 to rotate. The rotating shaft 303 drives the connecting plate 304 to rotate. The telescopic plate 401 rotates driven by the connecting plate 304. After the level gauge 7 detects that the telescopic plate 401 is in a horizontal state, the motor 302 stops running. The air cylinder 402 runs to drive the push rod to move. The push rod pushes the telescopic plate 401 to move. When the visual sensor 8 detects that the guardrail plate is located in the middle position between the two moving plates 406, the air cylinder 402 stops running. The motor 403 runs to drive the gear 404 to rotate. The two racks 405 move towards each other driven by the gear 404. The two moving plates 406 move towards each other driven by the racks 405 until the pressure sensor 408 detects the pressure on the moving plate 406, and then the motor 403 stops running. The laser distance sensor 407 detects the distance between the two moving plates 406, and this distance is the wave height of the guardrail plate at this place.

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