Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction quality testing technology, specifically a road construction quality testing device. Background Technology
[0002] Asphalt pavement construction is a technically demanding project that requires strict adherence to specifications such as material proportions, temperature control, and process flow. The entire construction is only considered complete after passing inspection and acceptance. The compaction and smoothness tests during the acceptance process are two important indicators for judging the quality of asphalt pavement construction, and testing equipment is usually used to test the construction quality of the pavement.
[0003] Currently, quality acceptance testing of asphalt pavement construction typically involves inserting steel rods or plastic nails into the compacted asphalt surface and measuring the insertion depth of the markings. This testing method can easily cause irreversible damage to the completed asphalt pavement, adversely affecting its service life. Furthermore, some testing equipment with signal detection functions usually only records the signals detected by the equipment, without marking the defective areas on the surface. This makes it impossible to subsequently address the defects based on the marked points, resulting in a time-consuming asphalt pavement remediation process. Utility Model Content
[0004] The purpose of this invention is to provide a road construction quality testing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a road construction quality inspection device, comprising a flat plate, a storage bin at the center of the top of the flat plate, a connecting pipe penetrating the bottom of one side wall of the storage bin, the storage bin being filled with marking paint, a column at the center of the top of the storage bin, a balance bar at the top of the column, a push-button switch on one side of the bottom of the balance bar, a pad on the other side of the bottom of the balance bar, a driven roller rotatably connected to one side of the bottom of the flat plate, an electric roller on the other side of the bottom of the flat plate, a vertical cylinder fixedly connected to the center of one side wall of the flat plate, a drip nozzle penetrating the bottom of the vertical cylinder, a solenoid valve at the connection between the drip nozzle and the vertical cylinder, and a counterweight on the front of the flat plate.
[0006] Preferably, the outer side of the balance bar is covered with an outer cover, and the bottom end of the outer cover is connected to the top end of the storage box.
[0007] Preferably, the top of the column has a groove, and a rotating rod is rotatably connected to the connection between the balance bar and the groove. The balance bar is rotatably connected to the column through the rotating rod.
[0008] Preferably, the push-button switch and the pad are both located at the top of the storage box, and the outer cover is connected to both the push-button switch and the pad.
[0009] Preferably, a battery is provided at the bottom of the flat plate, the push-button switch is electrically connected to the battery and the solenoid valve respectively, and the battery is electrically connected to the electric roller.
[0010] Preferably, the end of the connecting pipe extends through the bottom of the vertical cylinder, and the vertical cylinder is connected to the interior of the storage box through the connecting pipe.
[0011] Preferably, top balls are fixedly connected to both sides of the bottom end of the balance bar, and the two ends of the balance bar are in contact with the top of the button switch and the top of the pad respectively through the top balls.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This road construction quality inspection device, through an electric roller, a driven roller, a balance bar, and a column, allows the device to inspect the quality of the completed asphalt surface layer by moving along it. When the asphalt surface layer is found to be uncompacted or uneven, the balance bar will swing on both sides of the column. At this time, the inspectors can make inferences based on the amplitude of the balance bar swing, thereby achieving non-destructive testing of the asphalt surface layer.
[0014] 2. This road construction quality inspection device, through a push-button switch, marking paint, nozzles, and a solenoid valve, can trigger the push-button switch when the balance bar on the device swings. This causes the solenoid valve, which controls the nozzles to spray the marking paint, to open. The marking paint is then dripped from the nozzles under gravity and falls onto the asphalt pavement when the balance bar swings, thus marking the defects in the asphalt surface layer. This allows rectification personnel to carry out targeted rectification based on the marked points on the asphalt surface layer, effectively saving time for subsequent asphalt surface layer rectification.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] like Figures 1 to 4As shown, the road construction quality inspection device of this embodiment includes a flat plate 1. A storage box 6 is provided at the middle of the top of the flat plate 1. A connecting pipe 7 passes through the bottom of one side wall of the storage box 6. The inside of the storage box 6 is filled with marking paint 16. A column 3 is provided at the middle of the top of the storage box 6. A balance bar 4 is provided at the top of the column 3. A push button switch 11 is provided on one side of the bottom of the balance bar 4. A pad 14 is provided on the other side of the bottom of the balance bar 4. A driven roller 10 is rotatably connected to one side of the bottom of the flat plate 1. An electric roller 5 is provided on the other side of the bottom of the flat plate 1. A vertical cylinder 8 is fixedly connected to the middle of one side wall of the flat plate 1. A drip nozzle 9 passes through the bottom of the vertical cylinder 8. A solenoid valve 17 is provided at the connection between the drip nozzle 9 and the vertical cylinder 8. A counterweight 18 is provided on the front of the flat plate 1.
[0024] Specifically, the function of the plate 1 is to support the electric roller 5 and the driven roller 10, ensuring their stability during rotation. The top of the storage bin 6 is equipped with a replenishment port for timely replenishment of marking paint 16. The marking paint 16 is white or yellow road marking paint, which is highly visible when dripped onto the asphalt surface, making it easier for rectification personnel to quickly identify defects. The column 3 supports the balance bar 4, allowing it to swing left and right under the influence of the plate 1. The push-button switch 11 controls the start and stop of the solenoid valve 17. When the ball on the balance bar 4 triggers the push-button switch 11, the solenoid valve 17 opens promptly, allowing the marking paint to be applied. Paint 16 can be dripped onto the ground through nozzle 9, thereby marking the defect location on the ground. The pad 14 is made of silicone, which has good elasticity and can protect the end of the balance bar 4 away from the button switch 11, while also facilitating the swing of the balance bar 4. After the power supply provided by the battery 15 is turned on, the electric roller 5 can act as a drive structure to drive the plate 1 and the driven roller 10 to roll along the asphalt surface, thereby realizing the continuous detection of the asphalt surface by this detection device. The nozzle 9 can make the marking paint 16 gather and drip from the bottom of the vertical cylinder 8, thereby marking the uncompacted or uneven areas of the asphalt surface, which is convenient for subsequent targeted rectification and repair of the asphalt surface, while saving time for asphalt surface rectification and repair.
[0025] Furthermore, an outer cover 2 is provided on the outside of the balance bar 4. The bottom end of the outer cover 2 is connected to the top of the storage box 6. The outer cover 2 is made of transparent resin material, which can avoid interference from external factors such as natural wind and rain on the swing of the balance bar 4, and also facilitate the inspection personnel to observe the swing of the balance bar 4.
[0026] Furthermore, a groove 19 is provided on the top of the column 3, and a rotating rod 13 is rotatably connected to the connection between the balance bar 4 and the groove 19. The balance bar 4 is rotatably connected to the column 3 through the rotating rod 13. During the movement of the plate 1, the balance bar 4 will be driven to swing by the vibration generated by the electric roller 5 and the driven roller 10 along the uneven asphalt surface. This allows the detected unevenness of the surface to be presented by the swinging of the balance bar 4, making the test results more intuitive and easier for the testers to make a judgment.
[0027] Furthermore, both the push button switch 11 and the pad 14 are located on the top of the storage box 6. The outer cover 2 is connected to the push button switch 11 and the pad 14 respectively, so that the push button switch 11 can be continuously protected by the outer cover 2 during use, thereby facilitating the normal operation of the push button switch 11.
[0028] Furthermore, a storage battery 15 is provided at the bottom of the flat plate 1. The push-button switch 11 is electrically connected to the storage battery 15 and the solenoid valve 17 respectively. The storage battery 15 is electrically connected to the electric roller 5. The storage battery 15 can provide power for the normal operation of this device.
[0029] Furthermore, the end of the connecting pipe 7 extends through the bottom of the vertical cylinder 8. The vertical cylinder 8 is connected to the interior of the storage box 6 through the connecting pipe 7. The marking paint 16 in the storage box 6 can flow into the vertical cylinder 8 by gravity along the connecting pipe 7, thereby realizing the subsequent dripping of the marking paint 16 from the nozzle 9.
[0030] Furthermore, top balls 12 are fixedly connected to both sides of the bottom end of the balance bar 4. The two ends of the balance bar 4 contact the top of the push button switch 11 and the top of the pad block 14 respectively through the top balls 12. The surface of the top balls 12 is smooth, so that the balance bar 4 can more accurately strike the push button switch 11, thereby realizing the control of the solenoid valve 17 by the push button switch 11.
[0031] The method of using this embodiment is as follows: Before using this road construction quality inspection device, the storage bin 6 needs to be filled with marking paint 16. Then, the electric roller 5 can be started, so that the electric roller 5 rotates under the power provided by the battery 15, driving the driven roller 10 to roll against the asphalt surface layer, so that the plate 1 moves along the asphalt surface layer. When the plate 1 moves to an uncompacted or uneven asphalt surface layer, the electric roller 5 and the driven roller 10 will vibrate due to the uneven road surface, and transmit the vibration to the plate 1, so that the top of the plate 1 is balanced. After being vibrated by the plate 1, the rod 4 swings left and right in the groove 19 of the column 3, so that the two ends of the balance rod 4 contact the button switch 11 and the pad 14 respectively. When the top ball 12 at the bottom of the balance rod 4 contacts the top of the button switch 11 and triggers it, the button switch 11 will turn on the power of the solenoid valve 17, so that the solenoid valve 17 is opened. At this time, the marking paint 16 in the vertical cylinder 8 will flow from the vertical cylinder 8 into the drip nozzle 9 under gravity, and then fall from the bottom of the drip nozzle 9 onto the asphalt surface layer, so that the defective asphalt surface layer is marked.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
