Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a device for detecting the flatness of a road surface in construction engineering. Background Technique

[0002] The flatness of a road surface in construction engineering refers to the measurement of the flatness degree of the road surface, which is one of the important indicators for evaluating the road quality and driving comfort. Usually, the flatness of the road surface is evaluated by measuring the height difference or rut of the road surface. In construction engineering, in order to improve the flatness of the road surface, various technologies and materials are usually used, such as repairing road surface defects, laying appropriate road surface materials, adopting suitable construction methods, etc. Improving the flatness of the road surface can not only enhance the driving comfort and safety, but also reduce the wear and fuel consumption of vehicles, extend the service life of the road, and reduce the maintenance cost. Therefore, it has important significance in construction engineering;

[0003] It should be noted that in combination with the above content: during the use of traditional road surface flatness detection devices, affected by the comprehensive interference of road surface impurities or external factors, it is easy to have a certain impact on the accuracy of the detection results. At the same time, the lack of real-time marking of abnormal detection areas leads to confusion in positions during processing; and during the detection, there is no content for synchronous analysis and processing of detection data, which not only delays the overall detection efficiency, but also easily leads to abnormal positioning in the detection area;

[0004] In view of the above technical defects, a solution is proposed now. Summary of the Invention

Detailed implementation mode

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1: This embodiment is used to solve the problem that during the monitoring period, the lack of synchronous analysis and processing of detection data not only delays the overall detection efficiency but also easily leads to positioning anomalies in the detection area.

[0037] Please refer to Figure 1 - Figure 10 As shown, this embodiment is a device for detecting the flatness of a road surface in a construction project, including a detection frustum 1. A plurality of groups of horizontal lamp slots 101 are arranged on the outer side of the top of the detection frustum 1. A rotary motor 103 is arranged at the center of the top of the detection frustum 1. A support beam frame 2 is arranged on the top of the rotary motor 103. A movable extension beam 204 and an upper disc 5 are arranged on the top of the support beam frame 2. A plurality of groups of smooth detection mechanisms 3 are arranged on the outer wall of the movable extension beam 204;

[0038] The smooth detection mechanism 3 includes a sliding base 301 and a hollow pipe column 302, and a grounding conduction mechanism 4 is slidably arranged on the outer periphery of the bottom of the hollow pipe column 302. The grounding conduction mechanism 4 includes a support arm rod 401 and a detection arm rod 405. A detection roller 407 is arranged at the bottom of the detection arm rod 405. A mixing bin 503 is recessed in the center of the top of the upper disc 5, and a control panel 6 is arranged at the top of one side of the mixing bin 503. A pump bin 506 is arranged on the other side of the mixing bin 503. A stirring motor 505 is arranged at the center of the top of the mixing bin 503;

[0039] The control panel 6 is internally provided with a processor, a data acquisition module, a data analysis module and a signal execution module. The data acquisition module is used to collect the pressure fluctuation value YLz inside the smooth detection mechanism 3 and the lamp change and flicker value DBz at the top of the detection turntable 1 during the use of the detection device, send the pressure fluctuation value YLz and the lamp change and flicker value DBz to the data analysis module through the processor, and set 20 seconds during the use of the detection device as the time threshold;

[0040] It should be noted that: the pressure fluctuation value YLz represents the average value of the maximum and minimum values of the pressure borne by the compression spring member 305 obtained within the time threshold. The magnitude of the value of the pressure fluctuation value YLz reflects whether the road surface meets the flatness regulation range. Moreover, the larger the value of the pressure fluctuation value YLz, the more abnormal the flatness of the road surface detected within the time threshold. The lamp change and flicker value DBz represents the number of times the warning lamp operates and flickers inside the horizontal lamp groove 101. In addition, the pressure fluctuation value YLz is collected by a pressure sensor installed on the top of the compression spring member 305, and the lamp change and flicker value DBz is collected by a voltage sensor installed on the inner wall of the horizontal lamp groove 101;

[0041] After receiving the pressure fluctuation value YLz and the lamp change and flicker value DBz, the data analysis module immediately analyzes the operation efficiency of the detection device. The specific analysis process is as follows:

[0042] Obtain the pressure fluctuation value YLz and the lamp change and flicker value DBz within the time threshold, and through the formula Obtain the operation efficiency coefficient XLx, where a and b are the proportionality coefficients of the pressure fluctuation value YLz and the lamp change and flicker value DBz respectively, a > b > 0, XLx represents the operation efficiency coefficient, and immediately retrieve the preset operation efficiency coefficient YLx stored in the processor from the processor for comparison and analysis with the operation efficiency coefficient XLx;

[0043] If the operation efficiency coefficient XLx ≥ the preset operation efficiency coefficient YLx, it is determined that there is an abnormal flatness of the detection device within the time threshold, a marking signal is generated, and the generated marking signal is sent to the signal execution module through the processor. After receiving the marking signal, the signal execution module immediately controls the stirring motor 505 to work;

[0044] The water pump is connected to multiple groups of storage bins 501, mixing bins 503, hollow pipe columns 302, and marking nozzles 309 through pipelines. The stirring motor 505 drives the stirring paddle 504 to rotate inside the mixing bin 503 through a connecting piece, pre-mixing the pigments quantitatively extracted by the water pump, and extracting and conveying the pigments that have been stirred in the mixing bin 503 to the inside of the marking nozzle 309 through pipe fittings. The marking nozzle 309 applies pigment coating and spraying marks to the detected abnormal road surface area;

[0045] If the operating efficiency coefficient XLx < the preset operating efficiency coefficient YLx, no signal is generated.

[0046] Embodiment 2: This embodiment is used to solve the problems that during the use of traditional road surface flatness detection devices, due to the comprehensive interference of road surface impurities or external factors, it is easy to have a certain impact on the accuracy of the detection results, and at the same time, the lack of real-time marking of the detected abnormal areas leads to easy position confusion during processing.

[0047] Please refer to Figure 1 - Figure 9 As shown, this embodiment is a road surface flatness detection device for construction projects, including a circular bin 107 with a central depression inside the horizontal lamp slot 101, and multiple groups of contact switches are arranged on the inner wall of the circular bin 107. A balance ball 108 is arranged inside the circular bin 107. A guide rail 102 close to the rotating motor 103 is arranged on the top of the detection turntable 1. Multiple groups of adjusting cylinders 104 are arranged in an annular array on the outer periphery of the bottom of the detection turntable 1. A support pad 105 is arranged at the bottom of the adjusting cylinder 104. A combined suction cup 106 is arranged at the center of the bottom of the detection turntable 1, and the combined suction cup 106 is composed of multiple rubber disk parts sleeved in sequence;

[0048] Please refer to Figure 1 - Figure 4 As shown, during use, the device is transported to the center of the road surface area of the construction project waiting to be detected, and the device is started to run through the control panel 6. The air pump is connected to the combined suction cup 106 through pipe fittings. The combined suction cup 106 adsorbs and fixes the detection disk on the road surface. The balance ball 108 in the circular bin 107 offsets due to the balance state of the detection disk adsorbed and fixed on the road surface, for preliminarily detecting the flatness of the road surface area of the construction project in this area. When the detection turntable 1 is tilted, the balance ball 108 rolls away from the center of the circular bin 107 and presses the contact switch. The contact switch is hit and opens the lamp group on the inner wall of the horizontal lamp slot 101 connected to it by wire. The lamp group flashes to warn that the detection turntable 1 is tilted. Multiple groups of adjusting cylinders 104 operate in coordination. The adjusting cylinder 104 drives the support pad 105 to slide down and contact the road surface through a connecting piece, keeping the contact between the detection turntable 1 and the road surface horizontal;

[0049] The rotating electric machine 103 is sleeved with the bottom of the inner backing plate 202 through a connecting member, and drives the inner backing plate 202 to drive the support beam frame 2 to rotate. The bottom of the support beam frame 2 is connected to the guide rail 102 through the notch 201, ensuring the flatness of the rotation and movement of the support beam frame 2 along the top of the detection turntable 1. The support beam frame 2 rotates and carries the detection roller 407 to move in a circular trajectory with the detection turntable 1 as the axis, and performs contact detection on the road surface in the road surface area range of the construction project to be detected;

[0050] A plurality of groups of notches 201 are provided at the bottom of the support beam frame 2. The inner backing plate 202 is installed at the bottom of the inner wall of the support beam frame 2. A fixed driving beam 203 sleeved with the movable extension beam 204 is arranged at the top of the inner backing plate 202. An anti-slip strip 205 is arranged at the bottom of the movable extension beam 204. An inner chute 206 is recessed on the outer wall of the top of the movable extension beam 204;

[0051] Please refer to Figure 4 - Figure 8 As shown in the figure, a micro motor and a driving gear are embedded in the inner end face of the sliding base 301. The hollow pipe column 302 is sleeved through the outside of the sliding base 301. An arc-shaped sleeve 303 is arranged on the outer peripheral pipe wall at the bottom of the hollow pipe column 302. A limiting pressure ring 306 sleeved with the hollow pipe column 302 is arranged in the inner wall at the top of the arc-shaped sleeve 303. A compression spring member 305 is arranged at the bottom of the limiting pressure ring 306. A fine-tuning cylinder 304 connected to the limiting pressure ring 306 is arranged on the outer wall at the top of the arc-shaped sleeve 303. A pushing cylinder for connecting with the anti-slip strip 205 is arranged inside the fixed driving beam 203. The pushing cylinder pushes the movable extension beam 204 to move and extend outwards through the anti-slip strip 205 until the single-group radius areas on both sides of the road surface of the construction project to be detected are covered. The micro motor in the sliding base 301 contacts the inner wall of the inner chute 206 through the driving gear and pushes the sliding base 301 to move and unfold along the inner chute 206 until a certain detection distance is maintained between each group of sliding bases 301;

[0052] A moving collar 307 slidably sleeved with the inner wall of the arc-shaped sleeve 303 is arranged at the bottom of the compression spring member 305. An air jet valve 308 is arranged on the outer periphery at the bottom of the hollow pipe column 302. A marking nozzle 309 is arranged at the center of the bottom of the hollow pipe column 302;

[0053] During the detection process, when the detection roller 407 contacts a sunken road surface, the detection roller 407 slides down along the sunken area of the road surface. Under the extrusion thrust of the compression spring member 305, the supporting force fluctuation of the moving collar 307 is reduced. The compression spring member 305 pushes the moving collar 307 to slide down along the inner wall of the arc-shaped sleeve 303. The moving kit drives the support arm rod 401 and the detection arm rod 405 to slide down further, which can not only prompt the detection roller 407 to adhere to the road surface and slide down along the sunken area, but also the pressure sensor installed at the top of the compression spring member 305 continuously records the data fluctuation;

[0054] When the detection roller 407 comes into contact with a bumpy road surface, the detection roller 407 moves along the bumpy road surface, causing the detection arm rod 405 and the support arm rod 401 to push the moving collar 307 to slide upward along the inner wall of the arc-shaped sleeve 303. The upward sliding of the moving collar 307 squeezes and compresses the compression spring member 305, and the internal pressure sensor continuously records fluctuations in the data.

[0055] A connecting sleeve 402 is rotatably sleeved at the top of the support arm rod 401. A rotary cylinder 403 is arranged on the outer wall of the end face of the connecting sleeve 402. An embedded cylinder 404 connected to the detection arm rod 405 is arranged in the middle of the outer wall of the support arm rod 401. A sleeve shaft 406 connected to the detection roller 407 is arranged at the bottom of the detection arm rod 405. The embedded cylinder 404 drives the detection arm rod 405 to slide downward along the outer wall of the support arm rod 401 through a connecting member until the detection roller 407 abuts against the road surface of the construction project and extends by 5 cm. The excessive extension of the detection roller 407 causes the support arm rod 401 to push the moving collar 307 to slide upward along the inner wall of the arc-shaped sleeve 303 by 5 cm, ensuring a certain amount of moving space is reserved at the bottom of the moving collar 307. The support arm rod 401 is connected to the moving collar 307 through the connecting sleeve 402, and the support arm rod 401 is rotatably connected to the connecting sleeve 402 through the rotary cylinder 403. The fine-tuning cylinder 304 drives the limiting pressure ring 306 to slide downward along the outer circumference of the hollow pipe column 302 through a connecting member. The limiting pressure ring 306 pushes the compression spring member 305 to slide downward and abut against the top of the moving collar 307, constituting the intermediate debugging for the detection of the road surface of the construction project.

[0056] A stirring paddle 504 extending into the mixing bin 503 is arranged at the bottom of the stirring motor 505. Storage bins 501 are symmetrically arranged on both sides of the upper disc 5. Side clamping plates 502 are symmetrically arranged at the bottom of both sides of the upper disc 5. A micro air pump and a water pump are arranged inside the pump chamber 506. Before detection, the air pump is connected to the jet valve 308 through a pipe fitting. The air pump extracts air and transports it into the jet valve 308, and the jet plate pneumatically cleans the road surface of the construction project to be detected to avoid the influence of road surface impurities on the detection results.

[0057] Please refer to Figure 9 As shown, the water pump is connected to multiple storage bins 501, the mixing bin 503, the hollow pipe column 302, and the marking nozzle 309 through pipelines. The stirring motor 505 drives the stirring paddle 504 to rotate in the mixing bin 503 through a connecting member, pre-mixes the pigments quantitatively extracted by the water pump, and extracts and transports the pigments stirred in the mixing bin 503 into the marking nozzle 309 through pipe fittings. The marking nozzle 309 sprays and marks the abnormal road surface area with pigments.

[0058] Combined with Embodiment 1 and Embodiment 2, in this case, it can not only perform fixed-point level detection on the detection area to adjust the adaptability between the detection frustum 1 and the road surface, but also achieve a range coverage of the detection area through the telescopic structure. Then, by the coordinated operation of the smooth detection mechanism 3 and the grounding conduction mechanism 4, a rotary detection of the flatness of the detected road surface is constituted, and color spraying marks are made for the abnormally detected areas, so that both the detection accuracy and the effect are significantly improved.
