Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of road construction and maintenance devices, and particularly relates to a glass bead collecting device with road marking thickness detection function. BACKGROUND

[0002] Traffic marking can guide vehicles to converge and diverge, improve traffic driving conditions, increase traffic capacity, and reduce traffic accidents, and is therefore known as a lifeline. Related research shows that increasing the brightness coefficient of the pavement retroreflective can effectively reduce the probability of accidents, and the benefit-cost ratio of road signs and markings is 22.4, which is one of the most economical and effective measures to improve road safety.

[0003] However, problems such as the inability to identify markings in wet or rainy conditions result in a 3-fold increase in the rate of accidents in rainy or slippery road conditions, and the risk of post-management by construction and maintenance units also increases, resulting in a substantial increase in the investment of manpower, material resources, and social costs. Therefore, various types of night reflective marking that can be visible in the night environment have been developed, but the price of some ceramic night beads is high, so the promotion of ceramic night beads is severely limited.

[0004] At the same time, during the construction process of road marking, some glass beads do not fall on the paint when the glass beads are scattered on the road surface from the spreader, so these glass beads are invalid, resulting in waste of glass beads. At present, the collecting device for the glass beads scattered on the road surface of road marking at home and abroad has the problems of single function, many collected impurities, and inability to immediately enter construction, and therefore the glass bead collecting device with road marking thickness detection function is invented. The device can accurately and quickly detect the thickness of road marking, and solve the problems of the traditional STT-950 road marking thickness measuring instrument, such as the need to bend over during the measurement process, limited detection range, insufficient detection accuracy, low detection efficiency, and influence of impurities during the detection process. The device can collect the glass beads scattered on the road surface at one time, and according to a series of screening processes, the high-quality glass beads screened layer by layer are reused for the construction, reducing the waste and secondary transportation of glass beads and the cost of night marking.

[0005] Since the thickness detection of road marking is a mandatory item, it needs to be detected after the initial time of construction completion and a period of road operation. At the initial time of construction completion, the thickness detection of marking and the collection of glass beads can be performed at the same time; after a period of road operation, the thickness detection of marking is affected by the impurities covering the marking, and the impurities can be collected through the glass bead collecting port of the glass bead collecting device with road marking thickness detection function, which can significantly reduce the error of the thickness detection of marking caused by impurities.

[0006] Therefore, there is an urgent need for a device and method capable of recycling glass beads scattered on the road and measuring the thickness of the marking line to solve the problems in the prior art. SUMMARY

[0038] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0039] Reference Figures 1-6 As shown in the figure, the present application provides a glass bead collection device with road marking line thickness detection function, comprising: an outer shell 1, the bottom surface of the outer shell 1 is sequentially provided with a roller 2, a marking line thickness measurement structure 6 and a roller distance meter 3 from back to front.

[0040] The inside of the shell 1 is provided with an electric control system 5 and a filtering structure 7, the bottom surface of the filtering structure 7 is fixedly connected with a glass bead collecting port 11, the glass bead collecting port 11 is located in front of the roller range finder 3, the glass bead collecting port 11 is located below the shell 1, the top surface of the filtering structure 7 is fixedly connected with a connecting pipe 10, one end of the connecting pipe 10 away from the filtering structure 7 is fixedly connected with a screening structure 8, and the screening structure 8 is arranged on the top surface of the shell 1.

[0041] The shell 1 is fixedly connected with a handrail 4, the control structure 9 is arranged on the side surface of the handrail 4, the electric control system 5 is electrically connected with the control structure 9, and the filtering structure 7 is electrically connected with the screening structure 8.

[0042] By arranging the marking line thickness measuring structure 6, the thickness of the marking line can be conveniently detected during the glass bead collecting process, by arranging the filtering structure 7 and the glass bead collecting port 11, the glass beads can be well collected during the travel process, and the screening structure 8 can also be used to screen the collected glass beads and impurities, so that the glass beads with high roundness and the impurities or glass beads with low roundness are separated, the glass beads with high refractive index and the glass beads with low refractive index are separated, and thus a good screening effect is realized, and the subsequent recycling of the glass beads is facilitated.

[0043] The electric control system 5 comprises a power supply 501, a data storage 502, a distance measuring sensor 503 and a data processor 504. The power supply 501 is electrically connected with the first vibrator 703, the hot air blower 704, the impeller motor 706, the signal processor 8022, the laser detector 8023, the second vibrator 8025 and the glass bead shaper 8033.

[0044] The data storage 502, the distance measuring sensor 503 and the data processor 504 are electrically connected with the laser probe 602, the operation keyboard 901, the electronic display 902 and the broadcast printing device 903.

[0045] Further optimization scheme, the marking line thickness measuring structure 6 comprises a sliding guide rail 601, the sliding guide rail 601 is fixedly connected with the bottom surface of the shell 1, and the sliding guide rail 601 is slidably connected with a plurality of laser probes 602, and the laser probes 602 are electrically connected with the electric control system 5.

[0046] Preferably, five laser probes 602 are arranged on the sliding guide rail 601, and the laser probes 602 are arranged vertically to the road surface, the length of the sliding guide rail 601 is consistent with the width of the shell 1, and is greater than 45 cm, which is greater than the widest marking line width, so that various marking lines can be detected by the mechanical device.

[0047] The laser probe 602 located on both sides of the sliding guide rail 601 can be fixed by screws outside the measured road marking line width, and the laser emitted therefrom can be shot on the road surface. The distance from the laser probe 602 to the road surface can be calculated by the distance measuring sensor 503, and the data can be transmitted to the data processor 504. The three laser probes 602 located in the middle of the sliding guide rail 601 can be fixed by screws at the quarter point of the measured marking line width, and the laser emitted therefrom can be shot on the marking line. The distance from the laser probe 602 to the road surface can be calculated by the distance measuring sensor 503, and the data can be transmitted to the data processor 504. The data processor 504 is provided with a program:

[0048] (1) H (measured thickness of marking line) = L1 (average value of the distance from the two side laser probes 602 to the road surface) - L2 (average value of the distance from the three middle probes to the marking line);

[0049] (2) When H0 (design thickness of marking line) - ɑ1≤ H (measured thickness of marking line) ≤ H0 (design thickness of marking line) + ɑ2.

[0050] The measured thickness of the marking line is smaller than the design thickness by ɑ1, and larger than the design thickness by ɑ2 (ɑ2 is usually positive), and the data processing result is that the thickness of the marking line is qualified;

[0051] When H (measured thickness of marking line) > H0 (design thickness of marking line) + ɑ2 or H (measured thickness of marking line) < H0 (design thickness of marking line) - ɑ1, the data processing result is that the thickness of the marking line is unqualified;

[0052] Wherein ɑ1, ɑ2 can be selected by different parameters according to different marking line types, functions and other categories according to the relevant specifications of marking line detection;

[0053] (3) When the distance measured by the roller distance meter 3 is 100 meters, the distance traveled is displayed on the electronic display 902. When the distance displayed on the electronic display 902 is an integer multiple of 100, the key on the operation keyboard 901 is pressed, and the signal is transmitted to the laser probe 602 to emit 5 beams of laser, and the thickness of one three-point marking line is measured. The pass / fail condition of the thickness at this point is announced and printed by the announcement and printing device 903;

[0054] (4) When the pass rate is calculated at a frequency of 1 point per 100 meters, the pass rate (%) = thickness qualified point number / total number of thickness detection × 100%.

[0055] Since the thickness of the marking line is a key detection parameter, the pass rate is 95%. When the pass rate is greater than or equal to 95%, it is displayed that the thickness of the detection area passes the acceptance.

[0056] When the qualified rate is less than 95%, it is shown that the thickness of the detection area does not pass the acceptance, and finally the detection result is printed out from the broadcast printing device 903 in the form of a preset table, the mark line thickness, the qualified rate and whether it passes the acceptance of 3 points per 100 meters of detection.

[0057] Further optimization scheme, the filter structure 7 includes an outer cylinder 701, the outer cylinder 701 is fixedly connected with the inner side of the shell 1, the outer cylinder 701 is vertically arranged, the bottom surface of the outer cylinder 701 is fixedly communicated with the glass bead collecting port 11, the inner side of the outer cylinder 701 is sequentially fixedly connected with a first upper limit screen 702, a second upper limit screen 705 and a suction cylinder from bottom to top, the side surface of the outer cylinder 701 is communicated with an impurity separation structure, and the communication position of the impurity separation structure with the outer cylinder 701 is between the first upper limit screen 702 and the second upper limit screen 705;

[0059] The impeller motor 706 is electrically connected with the electric control system 5.

[0060] Further optimization scheme, the bottom surface of the first upper limit screen 702 is fixedly connected with a first vibrator 703, and the first vibrator 703 is electrically connected with the electric control system 5.

[0061] The glass beads and impurities sucked from the glass bead collecting port 11 are first screened through the first upper limit screen 702, and the first vibrator 703 can ensure that the glass beads can smoothly pass through the gap on the first upper limit screen 702, while the larger impurities are blocked. Then, the glass beads and the fine impurities pass between the first upper limit screen 702 and the second upper limit screen 705, the fine impurities are blown by the hot air blower 704 in the impurity separation structure and are collected into the fine impurity collecting bin 708 to realize collection. Finally, the glass beads are sucked into the impeller motor 706 through the second upper limit screen 705 and enter the roundness sorting bin 803 through the connecting pipe 10.

[0062] The setting of the first vibrator 703 can help the first upper limit screen 702 to screen, so that the glass beads can be quickly sucked into the upper part, and the possibility of partial blockage of the first upper limit screen 702 is reduced.

[0063] The scheme is further optimized. The impurity separation structure includes a fine impurity collection chamber 708 and a hot air blower 704.

The first storage chamber 801 is located at the high end, and one end of the connecting pipe 10 is connected to the roundness sorting chamber 803.

[0066] Glass beads enter the sphericity sorting chamber 803 in the screening structure 8 for sorting. Glass beads with low sphericity and impurities roll down the slope and enter the refractive index sorting chamber, while glass beads with high sphericity and impurities roll down the slope and enter the second storage chamber 804 for storage.

[0067] The scheme is further optimized. The refractive index sorting chamber 802 includes a refractive index sorting chamber shell 8021. The refractive index sorting chamber shell 8021 is tilted.

[0068] Several arrayed laser detectors 8023 are fixedly connected to the top surface of the inner side of the refractive index sorting chamber shell 8021;

[0069] An impurity collection tank 8026 is fixedly connected to the bottom inner side of the refractive index sorting chamber shell 8021. A bead groove plate 8024 is fixedly connected above the impurity collection tank 8026. The bead groove plate 8024 is provided with several arrayed openable bead groove structures. The openable bead groove structures correspond one-to-one with the laser detector 8023. A second vibrator 8025 is fixedly connected to the bottom high end of the bead groove plate 8024. There is no openable bead groove structure at the connection between the second vibrator 8025 and the bead groove plate 8024.

[0070] A signal processor 8022 is fixedly connected to the top of the refractive index sorting chamber shell 8021. The signal processor 8022 is electrically connected to the laser detector 8023, the openable bead groove structure, and the second vibrator 8025.

[0071] Reference Figure 6 As shown, the openable bead groove structure includes a bead groove opened on a bead groove plate 8024. A cap 8028 is provided below the bead groove.

[0073] The scheme is further optimized. The roundness sorting chamber 803 includes a roundness sorting chamber shell 8031. The roundness sorting chamber shell 8031 ​​is inclined. The high end of the roundness sorting chamber shell 8031 ​​is fixedly connected to the low end of the refractive index sorting chamber shell 8021. The low end of the roundness sorting chamber shell 8031 ​​is fixedly connected to the second storage chamber 804.

[0074] A glass bead sorter 8033 is fixedly connected to the bottom surface of the roundness sorting chamber shell 8031. The glass bead sorter 8033 is set at an angle, and the high end of the glass bead sorter 8033 is flush with the low end of the bead groove plate 8024.

[0075] The roundness sorting bin shell 8031 ​​has a feed inlet 8032 on one side, and the feed inlet 8032 is fixedly connected to one end of the connecting pipe 10.

[0076] Both the refractive index sorting chamber shell 8021 and the sphericity sorting chamber shell 8031 ​​are cuboid in shape. The openable bead groove structure matches the shape of the glass beads to be collected. If the glass beads to be collected are spherical, the openable bead groove structure is hemispherical. If the glass beads to be collected are ellipsoidal, the openable bead groove structure is semi-ellipsoidal. The aperture size of the openable bead groove structure is adapted to the particle size of the glass beads to be collected.

[0077] When glass beads with low sphericity and impurities roll into the openable bead groove structure under the vibration of the second vibrator 8025 with a small amplitude, the laser detector 8023 emits a laser beam onto the glass beads or impurities. If the glass beads in the openable bead groove structure have a high refractive index, the laser detector 8023 can receive a stronger refracted light beam and transmit the optical signal and the time difference between the emitted and received light beams to the signal processor 8022. The signal processor 8022 has a built-in program:

[0078] The distance S1 between the light source emission point of the laser detector 8023 and the upper surface of the glass bead or impurity, and the distance S2 between the upper surface of the glass bead or impurity and the lower surface, can be adjusted to make the difference between S1 and S2 smaller. This can reduce the error in judging the refractive index of the measured particle by the time difference of laser propagation in different media.

[0079] Let t1 be the time it takes for the laser to travel over a distance twice S1, and t2 be the time it takes for the laser to travel over a distance twice S2. Then we have:

[0080] T = t1 + t2

[0081]

[0082] Where C is the speed of light (3*10) 8 (m / s), where V is the speed at which the laser propagates through the glass bead or impurities.

[0083] Since the collected material has already yielded glass beads or impurities with a particle size similar to the target glass beads in the filter structure 7, S1 can be determined as a constant, and t1 is also a constant. Therefore, we have:

[0084]

[0085] Where n can be determined based on the refractive index of the glass beads to be screened.

[0086] When the laser detector 8023 receives strong light, and The bead slot structure will not open, and the glass beads are vibrated by the second vibrator 8025 into the second storage compartment 804 for collection, where they can be used directly as high-quality glass beads; when the laser detector 8023 cannot receive strong light or If the particle on a single openable bead groove structure is identified as an impurity, the openable bead groove structure is opened, and the impurity falls into the impurity collection groove 8026.

[0087] The scheme is further optimized. The control structure 9 includes an operation keyboard 901, which is fixedly connected to the side of the armrest 4. An electronic display 902 is rotatably connected to one end of the operation keyboard 901. A broadcasting and printing device 903 is provided on the side of the operation keyboard 901.
