Abstract
Description
Technical Field
[0001] This application relates to the field of road surface testing technology, and in particular, to a road surface smoothness testing device. Background Technology
[0002] The information provided in this section is for the purpose of generally presenting the background of this application. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this application.
[0003] After the construction of reinforced concrete pavement, it is often necessary to conduct pavement smoothness testing. During the construction process of reinforced concrete pavement, problems such as uneven concrete pouring, insufficient compaction, and uneven formwork installation may occur. These problems can all lead to uneven pavement. By conducting smoothness testing, these problems can be detected in time so that corresponding repair measures can be taken to ensure that the construction quality of the pavement meets the design requirements.
[0004] For example, Chinese patent application CN202323626418.7 discloses a road surface smoothness testing device for highway construction. This device detects road surface smoothness by moving a level. However, existing road surface smoothness testing devices cannot clean various impurities on the road surface. When the drive wheel moves to gravel or accumulated dust on the road surface, it can cause the level to misalign, failing to accurately reflect the actual smoothness of the road surface and resulting in inaccurate test results, which inconveniences the workers. Because the smoothness testing device lacks an automatic cleaning function, manual cleaning is required when encountering obstacles on the road surface. This not only increases the labor intensity but also reduces testing efficiency. Especially when testing large areas of road surface, frequent manual intervention can seriously affect the testing progress. Utility Model Content

[0009] In some embodiments of this application, the swing assembly includes a movable frame and a pusher. The movable frame has a groove, and a movable block is used to pass through the groove and is limited by the groove. The bottom end of the movable frame is hinged to the side wall of the mounting plate, and the pusher is connected to the bottom end of the movable frame.

[0026] The embodiments of this application are described in detail below with reference to the accompanying drawings; however, this application may be implemented in a variety of different ways as defined and covered below.

[0028] A road surface smoothness testing device includes a testing platform 1, a level 2, a moving mechanism 3, a translation mechanism 5, a lifting mechanism 7, and a brush 9.
[0029] A level 2 is set on the testing platform 1, a moving mechanism 3 is set at the bottom of the testing platform 1, the moving mechanism 3 is used to move the testing platform 1, a translation mechanism 5 is set at the front end of the testing platform 1, a lifting mechanism 7 is connected to the translation mechanism 5, and a brush 9 is connected to the lifting mechanism 7, the lifting mechanism 7 is used to drive the brush 9 to move up and down, and the translation mechanism 5 is used to drive the lifting mechanism 7 and the brush 9 to move horizontally back and forth so that the brush 9 can sweep away the impurities on the road surface in front of the testing platform 1.
[0030] It should be noted that the lifting mechanism 7 can use mature linear drive components such as electric push rods or linear motors, which helps reduce procurement costs and facilitates later maintenance and replacement. In addition, in some embodiments, the lifting mechanism 7 is connected to the translation mechanism 5 through the mounting bracket 6, and the lifting mechanism 7 and the brush 9 can be disassembled and assembled as a whole by removing and installing the mounting bracket 6, which facilitates later maintenance and cleaning.
[0031] In some embodiments, the "moving mechanism 3" mentioned here includes rollers. The movement of the inspection table 1 can be achieved by providing rollers at the bottom of the inspection table 1.
[0032] In some embodiments, the brush 9 is disposed at the bottom of the lifting plate 8, which is connected to the lifting mechanism 7, and the brush 9 can be cleaned separately by disassembling and assembling the lifting plate 8.
[0033] The road surface smoothness testing device of this application moves the testing platform 1 via the moving mechanism 3, allowing the smoothness of the road surface to be determined by observing the level 2 on the testing platform 1. To eliminate the influence of gravel or accumulated dust and other impurities on the road surface in front of the testing platform 1, the translation mechanism 5 at the front end of the testing platform 1 drives the lifting mechanism 7 and the brush 9 to reciprocate horizontally. The lifting mechanism 7 can also move the brush 9 up and down, enabling the brush 9 to perform horizontal reciprocating cleaning after contacting the road surface. This effectively removes impurities from the road surface, preventing any impact on the stability of the testing platform 1, ensuring the accuracy of the road surface smoothness testing, reducing the workload of manual road cleaning, and improving testing efficiency.
[0034] Preferably, please refer to Figure 1 and 2 As shown, the translation mechanism 5 includes a motor 51, a turntable 52, a swing assembly, and a slide rod 57. A mounting plate 4 is provided at the front end of the detection table 1. The motor 51 is mounted on the mounting plate 4. The turntable 52 is connected to the output shaft of the motor 51. The slide rod 57 is slidably mounted on the side wall of the mounting plate 4 in the horizontal direction. The lifting mechanism 7 is mounted on the slide rod. The middle part of the swing assembly is hinged to the side wall of the mounting plate 4. A movable block 53 is provided on the side wall of the turntable 52. The first end of the swing assembly is slidably connected to the movable block 53. The second end of the swing assembly abuts against the slide rod 57. The motor 51 is used to drive the turntable 52 to rotate and push the first end of the swing assembly through the movable block 53, so that the swing assembly swings back and forth around its hinge point, thereby causing the second end of the swing assembly to push the slide rod 57 to move back and forth in the horizontal direction.
[0035] Understandably, the motor 51 is mounted horizontally on the mounting plate 4. The motor 51 drives the turntable 52 to rotate, and the movable block 53 on the turntable 52 pushes the swing assembly to swing around the hinge point in the middle. This allows the second end of the swing assembly to push the slide rod 57 to move back and forth in the horizontal direction. The slide rod 57 drives the lifting mechanism 7 and the brush 9 to move back and forth in the horizontal direction, so that the brush 9 can clean the road surface in front of the testing platform 1, effectively reducing the impact of road surface impurities on the testing process. Moreover, there is no need for manual cleaning of the road surface, which greatly reduces the workload and labor intensity of workers.
[0036] In this preferred embodiment, the swing assembly includes a movable frame 54 and a pusher 56. The movable frame 54 has a groove 55. The movable block 53 is used to pass through the groove 55 and is limited by the groove 55. The bottom end of the movable frame 54 is hinged to the side wall of the mounting plate 4. The pusher 56 is connected to the bottom end of the movable frame 54 and the bottom end of the pusher 56 abuts against the slide rod 57.
[0037] It is understood that the movable frame 54 is slidably connected to the movable block 53 through the slide groove 55. Preferably, the movable frame 54 has a strip-shaped slide groove 55, which limits the movable block 53. When the turntable 52 rotates, the turntable 52 drives the movable block 53 to rotate. The movable block 53 pushes the movable block 53 to swing around its bottom hinge point. In turn, the movable block 53 drives the pusher 56 to swing, so that the pusher 56 pushes the slide rod 57 to move back and forth in the horizontal direction. This drives the lifting mechanism 7 and the brush 9 to move back and forth in the horizontal direction, and the brush 9 can efficiently clean the road surface.
[0038] Optionally, the bottom end of the movable frame 54 is connected to the side wall of the mounting plate 4 via a drive shaft, which facilitates the assembly and disassembly of the movable frame 54.
[0039] In a preferred embodiment, please refer to Figure 2 As shown, the bottom edge of the pusher 56 is an arc-shaped structure, and the bottom edge of the pusher 56 is provided with a first serration, while the side wall of the slide rod 57 is provided with a second serration, which is used to mesh with the first serration.
[0040] It is understandable that the arc-shaped bottom edge of the pusher 56 engages with the second sawtooth on the side wall of the slide bar 57 through the first sawtooth. When the turntable 52 drives the movable frame 54 and the pusher 56 to swing back and forth, the pusher 56 continues to abut against the slide bar 57. The pusher 56 can push the slide bar 57 to move horizontally back and forth, thereby driving the lifting mechanism 7 and the brush 9 to move horizontally back and forth, so as to increase the cleaning area of the brush 9 and achieve efficient road cleaning.
[0041] In another preferred embodiment, the bottom edge of the pusher 56 is an arc-shaped structure, and an anti-slip pad is provided between the pusher 56 and the slide rod 57. Specifically, the bottom edge of the pusher 56 is an arc-shaped structure and a first anti-slip pad is provided on the bottom edge of the pusher 56, while a second anti-slip pad is provided on the side wall of the slide rod 57.
[0042] It is understood that the curved bottom edge of the pusher 56 can abut against the second anti-slip pad on the side wall of the slide rod 57 through the first anti-slip pad. When the turntable 52 drives the movable frame 54 and the pusher 56 to swing back and forth, the pusher 56 continues to abut against the slide rod 57, and can push the slide rod 57 to move horizontally back and forth through the pusher 56, thereby driving the lifting mechanism 7 and the brush 9 to move horizontally back and forth, so as to increase the cleaning area of the brush 9 and achieve efficient road cleaning. In this preferred embodiment, the anti-slip pad can be replaced, which is beneficial for later maintenance and extends the service life of the parts.
[0043] Preferably, please refer to Figure 2 As shown, the side wall of the mounting plate 4 is provided with a guide sleeve 16, and the slide rod 57 passes through the guide sleeve 16 in the horizontal direction. The guide sleeve 16 is used to guide the slide rod 57 to make horizontal displacement.
[0044] Understandably, the guide sleeve 16 on the side wall of the mounting plate 4 limits the sliding rod 57 and guides its horizontal displacement, ensuring the smoothness of its horizontal reciprocating movement. Specifically, two guide sleeves 16 are provided, spaced apart, with both ends of the sliding rod 57 passing through both guide sleeves 16 simultaneously. This ensures the stability of the sliding rod 57 during installation and prevents it from detaching from the guide sleeves 16 during horizontal movement.
[0045] Preferably, please refer to Figure 4 As shown, the inside of the testing station 1 is provided with a collection chamber 12, and a dust collection hood 10 is provided on the outer side of the side wall of the testing station 1. The dust collection hood 10 is connected to the collection chamber 12. An exhaust fan 15 is provided on the side wall of the collection chamber 12. The exhaust fan 15 is used to exhaust the air in the collection chamber 12, and then the dust collection hood 10 is used to extract dust and impurities in the air around the testing station 1.
[0046] It is understandable that by opening a collection chamber 12 inside the testing platform 1, and installing a dust collection hood 10 on the outer side wall of the testing platform 1, and the dust collection hood 10 being connected to the collection chamber 12, the air in the collection chamber 12 can be drawn out by the exhaust fan 15 on the side wall of the collection chamber 12, and then the air around the testing platform 1 and the impurities in the air can be drawn out by the dust collection hood 10 and enter the collection chamber 12. This reduces the phenomenon of excessive dust and other impurities being generated by the brush 9 when sweeping the road surface and floating around the testing platform 1, and avoids dust falling on the surface of the level 2 or affecting the staff, thereby ensuring the smooth completion of the road surface flatness test.
[0047] Optionally, the dust collection hood 10 is connected to a pre-set opening on the side wall of the collection chamber 12 via a connecting pipe 11, so as to realize the communication between the dust collection hood 10 and the collection chamber 12, and to facilitate the setting of the opening orientation angle of the dust collection hood 10.
[0048] Preferably, please refer to Figure 4 As shown, a filter assembly is installed inside the collection chamber 12, which is used to filter the air drawn out by the exhaust fan 15.
[0049] Understandably, by installing a filter assembly in the collection chamber 12, the gas discharged by the exhaust fan 15 is prevented from containing too many impurities, thereby reducing the impact on the testing instruments and personnel and improving the comfort of workers during the testing process.
[0050] Preferably, please refer to Figure 4 As shown, the filter assembly includes a first filter screen 13 and a second filter screen 14. The first filter screen 13 and the second filter screen 14 are arranged in the collection chamber 12 and are both located in front of the air inlet of the exhaust fan 15.
[0051] Understandably, multi-stage gas filtration can be achieved through the first filter 13 and the second filter 14, which significantly reduces the content of dust and other impurities in the gas discharged by the exhaust fan 15, effectively reducing the impact of dust on workers and protecting their respiratory health.
[0052] Preferably, the road surface smoothness testing device further includes a push rod, which is located at the rear end of the testing platform 1.
[0053] Understandably, by setting a push rod at the rear end of the testing table 1, workers can easily move the testing table 1 by pushing the push rod, which helps to improve the overall ease of operation of the testing device.
[0054] When using the system, if a worker needs to test the smoothness of a road surface, they first move the testing platform 1 to the area to be tested. Then, the worker opens the lifting mechanism 7, causing the lifting plate 8 to descend, bringing the bottom of the brush 9 into contact with the ground. The worker can then push the testing platform 1 forward. Simultaneously, the motor 51 on the side wall of the mounting plate 4 is activated, causing the sliding rod 57 to move horizontally back and forth. As the testing platform 1 moves forward, the brush 9 cleans up accumulated dust, pebbles, or other impurities on the ground, preventing the moving mechanism 3 from passing over them. While pushing the platform, the worker can observe the level 2 above the testing platform 1 to check the road surface smoothness. During the test, the worker can turn on the exhaust fan 15, causing the dust collection hood 10 to absorb the dust generated during cleaning, preventing dust from falling on the surface of the level 2 or affecting the worker. This completes the road surface smoothness test.
