Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of road surface detection, and more specifically, to a traffic engineering quality detection device. Background Art

[0002] The evenness of a road surface refers to the smoothness of the road surface, which is one of the important indicators for measuring road quality. Good road surface evenness can not only improve the safety and comfort of driving, but also reduce the impact force on the road surface when the vehicle is driving, thereby extending the service life of the road and reducing maintenance costs. To evaluate and monitor the evenness of the road surface, special equipment and technologies are usually adopted, such as using traffic engineering quality detection equipment for measurement, and corresponding maintenance measures are taken according to the measurement results. In some countries and regions, relevant standards and specifications have also been formulated to define the evenness requirements that different grades of roads should meet.

[0003] In the prior art, the evenness of the road surface is usually detected by combining a detection wheel with a variety of sensors. During the detection process, the sensor records the bump amplitude during the movement of the detection wheel, and then the evenness of the road surface is calculated by the vehicle computer. However, during the detection process, it is impossible to accurately and intuitively judge which specific section of the engineering road does not meet the standard, and it is impossible to mark the non-compliant engineering road area immediately during the detection process, which affects the repair efficiency of the subsequent repair work of the detected road by the detection personnel. Moreover, the existing detection wheel can only move according to the left and right movement of the vehicle, and on a narrow road surface, only a very small range of the road surface can be detected, and the accuracy of the detected data is relatively low.

[0025] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0026] As Figures 1 to 6 shown, it shows a traffic engineering quality detection device in an embodiment of this disclosure, including a rear frame 1, a rear wheel frame 2 is fixedly connected to the rear part of the rear frame 1, two mounting frames 3 are fixedly connected to the lower end of the rear wheel frame 2, and rear fixed wheels 4 are rotatably mounted at both the front and rear ends of the mounting frame 3; a front frame 5, which is movably mounted between the front frame 5 and the rear frame 1, a front wheel frame 6 is fixedly connected to the front end of the front frame 5, two connecting frames 7 are fixedly connected to the lower part of the front wheel frame 6, and a front fixed wheel 8 is fixedly connected to the rear part of the connecting frame 7; a connecting plate 9, movable plates 10 are rotatably mounted at both the left and right ends of the connecting plate 9, a steering wheel 11 is fixedly connected to the rear part of the movable plate 10, and a fixing plate 12 is rotatably mounted between the two steering wheels 11; a linear motor 13, a mounting shell 14 is fixedly connected to the moving end of the linear motor 13; a detection mechanism 15, the detection mechanism 15 is arranged in the middle of the mounting shell 14; two spraying mechanisms 16, the two spraying mechanisms 16 are arranged on both the left and right sides of the mounting shell 14; Its function is that multiple rear fixed wheels 4, multiple front fixed wheels 8, and multiple steering wheels 11 provide a relatively stable platform for the detection wheel 156. During the detection process, it can drive the connecting plate 9 to move left and right, cause the two movable plates 10 to rotate, and then drive the steering wheels 11 to rotate, thereby realizing the steering of this device.

[0027] Among them, the detection mechanism 15 includes a sliding plate 151 and a barrel sleeve 158. Two quartz piezoelectric sensors 152 are arranged on both the upper and lower surfaces of the sliding plate 151. A connecting head 153 is fixedly connected to the middle of the sliding plate 151. A telescopic rod 154 is fixedly connected to the bottom of the connecting head 153. A rotating frame 155 is rotatably installed at the telescopic end of the telescopic rod 154. A detection wheel 156 is rotatably installed at the bottom end of the rotating frame 155. A plurality of limiting blocks 157 are fixedly connected to the surface of the telescopic rod 154. A plurality of limiting grooves 159 are formed inside the barrel sleeve 158; Its function is that the telescopic rod 154 will extend, so that the detection wheel 156 contacts the ground, and a certain initial pressure is applied to the upper quartz piezoelectric sensor 152 by the sliding plate 151, causing it to generate a certain amount of current. The existing processing controller records it as the initial current. Subsequently, the vehicle drives the present invention to move. When the detection wheel 156 passes through a potholed road surface, the detection wheel 156 will move downward, and the pressure of the sliding plate 151 on the upper quartz piezoelectric sensor 152 will decrease. Even, due to the gravity of the structure below the connecting head 153, the lower quartz piezoelectric sensor 152 will be squeezed; when the detection wheel 156 passes through a road surface protrusion, the detection wheel 156 will move upward, and the pressure of the sliding plate 151 on the upper quartz piezoelectric sensor 152 will increase, so that the upper quartz piezoelectric sensor 152 generates a larger current. At this time, the existing processing controller will monitor that the current of the upper quartz piezoelectric sensor 152 increases.

[0028] Among them, the spraying mechanism 16 includes a material box 161. A pressing plate 162 is arranged inside the material box 161. Two springs 163 are fixedly connected between the pressing plate 162 and the top of the material box 161. Two symmetric fixed ears 164 are fixedly connected to the upper surface of the pressing plate 162. The upper ends of the fixed ears 164 are slidably connected with a movable handle 165. A hose 166 is fixedly connected to the bottom end of the material box 161. A sprinkler 167 is fixedly connected to the bottom end of the hose 166. A feeding port 168 is provided at the front of the material box 161. A sealing plug 169 is movably installed inside the feeding port 168. The sprinkler 167 includes a spray shell 1671. A plurality of partition plates 1672 are fixedly connected inside the spray shell 1671. A plurality of nozzles 1673 are fixedly installed at the bottom of the spray shell 1671. A connecting shell 1674 is fixedly connected to the outside of the spray shell 1671. An electromagnet 1675 is fixedly connected inside the connecting shell 1674. A permanent magnet 1676 is arranged inside the electromagnet 1675. A control board 1677 is fixedly connected to the inside of the permanent magnet 1676; Its function is that the existing processing controller monitors a decrease in the current of the upper quartz piezoelectric sensor 152 and the generation of current by the lower quartz piezoelectric sensor 152, thereby controlling the electromagnet 1675 on one side to attract the permanent magnet 1676 to move outward along the connecting shell 1674, so that the upper part of the spraying shell 1671 is connected to the spray head 1673. Under the action of the two springs 163 pressing the pressure plate 162, the paint inside the material box 161 enters the spraying shell 1671 through the hose 166 and is sprayed out from the connected spray head 1673, thereby marking the potholes on the road surface. The greater the change in the decrease in the current of the upper quartz piezoelectric sensor 152 and the greater the current generated by the lower quartz piezoelectric sensor 152 monitored by the existing processing controller, the greater the distance that the electromagnet 1675 on one side attracts the permanent magnet 1676 to move outward along the connecting shell 1674, so that more spray heads 1673 are connected, and thus more paint is sprayed; when the existing processing controller monitors an increase in the current of the upper quartz piezoelectric sensor 152, it controls the electromagnet 1675 on the other side to attract the permanent magnet 1676 to move outward along the connecting shell 1674, and then the paint on this side is sprayed. Similarly, the greater the increase in the current of the upper quartz piezoelectric sensor 152 monitored by the existing processing controller, the more paint is sprayed on this side.

[0029] Among them, both of the two steering wheels 11 are rotatably connected to the front frame 5, and the linear motor 13 is fixedly connected to the front frame 5.

[0030] Among them, the sliding plate 151 is slidably connected to the mounting shell 14, the barrel sleeve 158 is fixedly connected to the bottom of the mounting shell 14, the limiting block 157 is slidably connected to the limiting groove 159, the upper quartz piezoelectric sensor 152 is fixedly connected to the moving end of the linear motor 13, and the lower quartz piezoelectric sensor 152 is fixedly connected to the mounting shell 14.

[0031] Among them, the material box 161 is fixedly connected to the mounting shell 14, the pressure plate 162 is adapted to the material box 161. Its function is that the upper part of the spraying shell 1671 is connected to the spray head 1673. Under the action of the two springs 163 pressing the pressure plate 162, the paint inside the material box 161 enters the spraying shell 1671 through the hose 166 and is sprayed out from the connected spray head 1673.

[0032] Among them, the spraying shell 1671 is fixedly connected to the rotating frame 155. The control board 1677 extends deep into the interior of the spraying shell 1671. A plurality of partition plates 1672 are located on the upper and lower sides of the control board 1677. An appropriate amount of compressed gas is filled between the electromagnet 1675 and the permanent magnet 1676. Its function is that when the electromagnet 1675 is energized, it attracts the permanent magnet 1676 to move outward along the connecting shell 1674, and the control board 1677 will move accordingly. During this process, the compressed gas is squeezed. The greater the distance the control board 1677 moves outward, the more nozzles 1673 are opened to the upper part of the spraying shell 1671, allowing more paint to be sprayed. When the electromagnet 1675 is de-energized, the compressed gas will push the permanent magnet 1676 and the control board 1677 to reset.

[0033] Among them, T-shaped grooves are provided at the front and rear of the material box 161, and the T-shaped grooves are adapted to the movable handle 165. Its function is that after removing the sealing plug 169, the movable handle 165 drives the fixed ear 164 and the pressing plate 162 to move upward, squeezing the spring 163. When the movable handle 165 is at the top of the T-shaped groove, the movable handle 165 slides to one side, so that the pressing plate 162 no longer moves downward, and then paint is filled into the interior of the material box 161 through the feeding port 168.

[0034] Among them, two material boxes 161 are filled with two different colors of paint. The inner end of the sealing plug 169 is flush with the inner wall of the material box 161. Its function is that the two sprayers 167 below will change accordingly with the rotation of the detection wheel 156. The existing processing controller will spray two different paints according to the potholes and protrusions on the road surface, and adjust the spraying amount of the paint according to the amplitude of the potholes and protrusions on the road surface, so as to make accurate markings.

[0035] Working principle: The existing vehicle drives this device to move through the connecting plate 9. The movable handle 165 is located in the middle of the T-shaped groove, allowing it to slide up and down; During use, the telescopic rod 154 will extend, causing the detection wheel 156 to contact the ground, and enabling the sliding plate 151 to apply an initial pressure to the quartz piezoelectric sensor 152 above it, generating a certain amount of current. The existing processing controller records it as the initial current. Subsequently, the vehicle drives the present invention to move. When the detection wheel 156 passes over a potholed road surface, the detection wheel 156 will move downward, reducing the pressure of the sliding plate 151 on the quartz piezoelectric sensor 152 above it. Even due to the gravity of the structure below the connector 153 pressing on the quartz piezoelectric sensor 152 below, at this time, the existing processing controller will monitor a decrease in the current of the quartz piezoelectric sensor 152 above and the generation of current by the quartz piezoelectric sensor 152 below. Thereby, it controls one side of the electromagnet 1675 to be energized to attract the permanent magnet 1676 to move outward along the connection shell 1674, making the upper part of the spray shell 1671 communicate with the nozzle 1673. Under the action of two springs 163 pressing the pressure plate 162, the paint inside the paint tank 161 enters the spray shell 1671 through the hose 166 and is sprayed out from the opened nozzle 1673, thereby marking the potholes on the road surface. The greater the change in the decrease in the current of the quartz piezoelectric sensor 152 above monitored by the existing processing controller and the greater the current generated by the quartz piezoelectric sensor 152 below, the greater the distance that one side of the electromagnet 1675 attracts the permanent magnet 1676 to move outward along the connection shell 1674, thereby opening more nozzles 1673 and resulting in more paint being sprayed; When the detection wheel 156 passes over a road surface protrusion, the detection wheel 156 will move upward, increasing the pressure of the sliding plate 151 on the quartz piezoelectric sensor 152 above it, thereby causing the quartz piezoelectric sensor 152 above to generate a larger current. At this time, the existing processing controller will monitor an increase in the current of the quartz piezoelectric sensor 152 above, thereby controlling the other side of the electromagnet 1675 to attract the permanent magnet 1676 to move outward along the connection shell 1674, and then causing the paint on this side to be sprayed. Similarly, the greater the increase in the current of the quartz piezoelectric sensor 152 above monitored by the existing processing controller, the more paint is sprayed on this side; During the operation of the present invention, the linear motor 13 can work uniformly and reciprocally, thereby driving the detection wheel 156 to regularly follow an S-shaped path, thereby increasing the detection area of the road surface flatness. During the process, the two sprayers 167 below will change accordingly with the rotation of the detection wheel 156, thereby performing precise marking.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not restrictive. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
