Description

Technical Field

[0001] This invention belongs to the technical field of road inspection devices, specifically relating to a device for inspecting the quality of road construction. Background Technology

[0002] During road construction, it is often necessary to inspect the smoothness of the road surface. The inspection device mainly consists of a housing, inspection components, a blowing component, and a pusher plate. In use, the housing moves along the road surface via wheels at its bottom. The inspection components use ultrasonic waves to calculate the elevation differences of the road surface, thereby inspecting the smoothness of the road surface. The blowing component blows away debris on the road surface, and debris that is difficult to blow away is pushed away by the pusher plate on the housing to reduce the impact of debris on the inspection components.

[0003] In existing road construction quality inspection devices, the output end of the blower assembly is generally fixedly connected to the housing, making it difficult to adjust the blowing direction. This results in the blower assembly always blowing in one direction, limiting the range of debris removal and making it difficult to adjust. This also makes it inconvenient to remove debris. Furthermore, after the pusher plate pushes the debris, the debris tends to remain in front of the pusher plate, hindering the pusher plate from pushing other debris. This requires manual cleaning of the debris on the pusher plate, which is also inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a road construction quality inspection device that can drive the first and second swing arms to rotate via wheels. This not only expands the blowing range of the blowing assembly but also enables the sweeping plate to clean up debris stuck in front of the push plate, improving the convenience of cleaning debris. Furthermore, it eliminates the need for an additional motor as a drive source, thus saving on the number of drive sources required.

[0009] As a preferred embodiment of the road construction quality inspection device described in this invention, the first swing arm is provided with a first sliding hole, and the end of the first rotating rod away from the second vertical axis is fixedly connected to a first sliding column. The first sliding column is slidably engaged with the first sliding hole, and the first sliding column is rotatably engaged with the first sliding hole.

[0010] As a preferred embodiment of the road construction quality inspection device described in this invention, one end of the second swing arm is rotatably connected to the housing, the other end of the second swing arm is fixedly connected to the cleaning plate, a second rotating rod is detachably installed on the second vertical shaft, and the end of the second rotating rod is slidably connected to the second swing arm.

[0011] As a preferred embodiment of the road construction quality inspection device described in this invention, the second rotating rod is rotatably connected to the second vertical shaft, the second vertical shaft is provided with a third limiting hole, and the end of the second rotating rod near the second vertical shaft is provided with a plurality of fourth limiting holes, the plurality of fourth limiting holes being circumferentially distributed around the axis of the second vertical shaft, and the third limiting hole and the fourth limiting holes are slidably connected by a second limiting pin.

[0012] As a preferred embodiment of the road construction quality inspection device of the present invention, the second swing arm is provided with a second sliding hole, the end of the second rotating rod away from the second vertical axis is fixedly connected to a second sliding column, the second sliding column is slidably engaged with the second sliding hole, and the second sliding column is rotatably engaged with the second sliding hole.

[0013] As a preferred embodiment of the road construction quality inspection device described in this invention, the push plate has a groove inside, a slider is fixedly connected to the sweeping plate, the slider slides in cooperation with the groove, a groove is provided on the outside of the push plate, and a roller is rotatably connected to the sweeping plate, the outside of the roller rolls in cooperation with the inner wall of the groove.

[0014] As a preferred embodiment of the road construction quality inspection device described in this invention, a cleaning roller is provided on the outer side of the wheel, the cleaning roller is in rolling contact with the outer surface of the wheel, and the cleaning roller is rotatably connected to the housing.

[0015] The technical effects achieved by this invention are as follows: This invention employs a blower mechanism and a cleaning mechanism. The first and second swing arms can rotate under the drive of the wheels. After the first swing arm rotates, it drives the output end of the blower assembly to rotate along the housing, thereby expanding the blowing range of the blower assembly to a fan-shaped area in front of the housing, improving the convenience of blowing away debris. After the second swing arm rotates, it drives the cleaning plate to slide along the push plate, allowing the cleaning plate to clean up the debris stuck in front of the push plate. This reduces the situation where debris is stuck in front of the push plate and hinders the push plate from continuing to push other debris. Moreover, the cleaning of these debris by the cleaning plate is completed during the forward movement of the device, reducing the need for manual cleaning of debris on the push plate and reducing the situation where manual cleaning of debris causes the device to stop moving forward and affects the device's detection process, thus improving the convenience of cleaning debris. The present invention adopts a wheel-driven design to rotate the first and second swing arms. The wheels can rotate as the device moves forward, eliminating the need for an additional motor as a drive source, thus reducing additional power consumption. Moreover, only the wheels are needed as a drive source. This not only expands the blowing range of the blower assembly by driving the first swing arm to rotate, but also enables the cleaning plate to clean up debris stuck in front of the push plate by driving the second swing arm to rotate, saving the number of drive sources. This invention employs a detachable first and second rotating rod design. Both the first and second rotating rods are detachable from the second vertical axis, facilitating the adjustment of the initial angular positions between the first and second rotating rods and the second vertical axis. This adjustment of the initial angular positions between the first and second rotating rods facilitates the adjustment of the initial angular positions between the first and second swing arms, thereby ensuring that the first and second swing arms are staggered during rotation. This not only reduces the possibility of the first and second swing arms simultaneously turning to one side of the housing, thus affecting the stability of the device, but also facilitates the cleaning plate to push any debris not yet blown away by the blowing assembly to the outside of the housing.

[0018] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0019] Example 1 like Figures 1 to 5 As shown, this is the first embodiment of the present invention. This first embodiment provides a road construction quality inspection device, including a housing 10, a wheel 11 rotatably mounted on the bottom of the housing 10, and a push plate 12 fixedly connected to the end of the housing 10; a blower mechanism 20, which is disposed on the housing 10 and includes a first swing arm 21 rotatably mounted on the housing 10, the first swing arm 21 being drivenly connected to the wheel 11, a blower assembly 22 fixedly connected to the housing 10, and the output end of the blower assembly 22 being fixedly connected to the end of the first swing arm 21; and a sweeping mechanism 30, which is disposed on the housing 10 and includes a second swing arm 31 rotatably mounted on the housing 10, the second swing arm 31 being drivenly connected to the wheel 11, and a sweeping plate 32 fixedly connected to the end of the second swing arm 31, the sweeping plate 32 being slidably connected to the push plate 12.

[0020] It should be noted that a detection component is installed inside the housing 10. This detection component is existing technology. It calculates the road elevation difference by emitting high-frequency sound waves to the road surface and receiving the reflected signals, using time difference and waveform changes. Further details are omitted here. The push plate 12 is located at the front end of the housing 10 in the direction of travel. The push plate 12 is arc-shaped, and its center coincides with the rotation center of the second swing arm 31 along the housing 10. The lateral dimension of the push plate 12 is larger than the lateral spacing of the wheels 11. The blowing component 22 is existing technology, but in this invention, it is preferably a fan. A blowing pipe is fixedly connected to the outlet end of the fan. The blowing pipe is a deformable flexible hose. The end of the blowing pipe away from the fan serves as the output end of the blowing component 22 and is fixedly connected to the end of the first swing arm 21. The blowing pipe and the end of the first swing arm 21 are fixedly connected by a clamp, which is existing technology. The clamp is tightened by bolts to adjust the tightness. The blower is fixed to the end of the first swing arm 21. The cleaning plate 32 is located outside the front end of the push plate 12. The first swing arm 21 is located above the second swing arm 31. The front end of the housing 10 has two openings. The height of the two openings is aligned with the height of the first swing arm 21 and the second swing arm 31, respectively, so that the ends of the first swing arm 21 and the second swing arm 31 can extend through the openings to the outside of the housing 10. A push rod frame is fixedly connected to the end of the housing 10 away from the push plate 12, so that the operator can move the housing 10 located on the road surface through the push rod frame. The outer surface of the wheel 11 rolls with the road surface. A column is fixedly connected inside the housing 10. The first swing arm 21 and the second swing arm 31 are both rotatably connected to the column. The first swing arm 21 and the housing 10 are rotatably connected together through the column. The second swing arm 31 and the housing 10 are rotatably connected together through the column.

[0021] In use, the operator pushes the push rod frame, causing the housing 10 to move closer to the push plate 12. This causes the wheel 11 to move forward with the housing 10 while simultaneously rolling along the road surface, resulting in relative rotation between the wheel 11 and the housing 10. The rotation of the wheel 11 causes the first swing arm 21 and the second swing arm 31 to rotate. After the first swing arm 21 rotates, its end causes the output end of the blower assembly 22 to rotate along the outside of the housing 10, unlike in the prior art where the output end of the blower assembly 22 is fixed in the direction of movement. Compared to the blowing method, this reduces the limited range and difficulty in adjusting the blowing assembly 22 for removing debris, expanding its blowing range to a fan-shaped area in front of the housing 10, thus improving the ease of debris removal. After the second swing arm 31 rotates, its end drives the cleaning plate 32 to slide along the push plate 12, causing the cleaning plate 32 to push the debris stuck in front of the push plate 12 to both sides of the push plate 12. After these debris separate from the push plate 12, they are distributed on both sides of the housing 10 in the forward direction, reducing the amount of debris stuck on the push plate 12. 2. To prevent the pusher plate 12 from affecting the subsequent pushing of other debris, since the lateral dimension of the pusher plate 12 is larger than the lateral spacing of the wheels 11, the situation where debris left behind after detachment affects the normal rolling of the wheels 11 along the road surface is reduced. The situation where debris detached after detachment collides with the wheels 11 and causes the housing 10 to bounce, affecting the detection component's detection of road surface flatness is also reduced. Compared with the prior art, the debris left in front of the pusher plate 12 can be cleared during the movement of the detection device along the road surface. This facilitates the clearing during the device's quality detection of road surface flatness, reduces the need for manual clearing of debris on the pusher plate 12, and reduces the need for manual clearing of debris, which would require the device to stop moving forward and cause the detection to pause. This improves the convenience of clearing debris. Furthermore, the rotation of the moving wheels 11 drives the first swing arm 21 and the second swing arm 31 to rotate. This not only requires only one drive source to expand the blowing range of the blowing component 22 and clear debris left in front of the pusher plate 12, saving the number of drive sources, but also eliminates the need for an additional motor as a drive source, reducing additional power consumption.

[0022] Example 2 Reference Figures 1 to 8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0023] like Figure 3 , Figure 5 and Figure 6As shown, an axle 41 is rotatably connected to the bottom inner side of the housing 10. The wheel 11 is fixedly connected to the axle 41. A first bevel gear 42 is fixedly connected to the axle 41. A first vertical shaft 43 and a second vertical shaft 44 are rotatably connected to the housing 10. A second bevel gear 45 and a first pulley 46 are fixedly connected to the first vertical shaft 43. The first bevel gear 42 and the second bevel gear 45 mesh with each other. A second pulley 47 is fixedly connected to the second vertical shaft 44. A transmission belt 48 connects the first pulley 46 and the second pulley 47.

[0024] It should be noted that a tensioning pulley is provided on the inner side of the transmission belt 48. The tensioning pulley is rotatably connected to the housing 10. The tensioning pulley is existing technology and is used to maintain the appropriate tension of the transmission belt 48. It will not be described in detail here.

[0025] According to the above structure, after the housing 10 moves forward along the road surface, the housing 10 drives the axle 41 and the wheel 11 to move forward along the road surface, so that the wheel 11 rolls along the road surface. The wheel 11 drives the axle 41 to rotate along the housing 10. The axle 41 drives the first vertical shaft 43 to rotate through the first bevel gear 42 and the second bevel gear 45. The first vertical shaft 43 drives the second pulley 47 to rotate through the first pulley 46 and the transmission belt 48, so that the second pulley 47 drives the second vertical shaft 44 to rotate.

[0026] like Figure 1 , Figure 3 and Figure 5 As shown, one end of the first swing arm 21 is rotatably connected to the housing 10, and the other end of the first swing arm 21 is fixedly connected to the output end of the blower assembly 22. A first rotating rod 51 is detachably mounted on the second vertical shaft 44, and the end of the first rotating rod 51 is slidably connected to the first swing arm 21.

[0027] It should be noted that the end of the first rotating rod 51 is also rotatably connected to the first swing arm 21.

[0028] According to the above structure, after the second vertical shaft 44 rotates, it drives the first rotating rod 51 to rotate. While the end of the first rotating rod 51 slides along the first swing arm 21, the end of the first rotating rod 51 also rotates along the first swing arm 21, so that the first swing arm 21 swings back and forth along the housing 10. This causes the end of the first swing arm 21 to drive the output end of the blower assembly 22 to swing back and forth left and right along the front end of the housing 10, which facilitates the blowing direction of the blower assembly 22 to move back and forth within the fan-shaped range at the front end of the housing 10, thereby facilitating the expansion of the blowing range of the blower assembly 22 and improving the convenience of blowing away debris.

[0029] like Figure 6 and Figure 7As shown, the first rotating rod 51 is rotatably connected to the second vertical shaft 44. The second vertical shaft 44 is provided with a first limiting hole 52. The first rotating rod 51 is provided with a plurality of second limiting holes 53 at one end near the second vertical shaft 44. The plurality of second limiting holes 53 are circumferentially distributed with the axis of the second vertical shaft 44 as the center. The first limiting hole 52 and the second limiting hole 53 are slidably connected to the inside of the first limiting hole 52 and the second limiting hole 53 by a first limiting pin 54.

[0030] It should be noted that the first rotating rod 51 and the second vertical shaft 44 are detachably connected together by the first limiting pin 54.

[0031] According to the above structure, when it is necessary to adjust the initial angular position between the first swing arm 21 and the second swing arm 31, the first limiting pin 54 is pulled out from the inside of the first limiting hole 52 and the second limiting hole 53, and the first rotating rod 51 is rotated along the first limiting pin 54 so that the first limiting hole 52 is aligned with the second limiting hole 53 in a suitable position. The first limiting pin 54 is then inserted into the first limiting hole 52 and the second limiting hole 53 to limit the first rotating rod 51 and the second vertical shaft 44, thereby adjusting the initial angular position between the first rotating rod 51 and the second vertical shaft 44. Since the first rotating rod 51 rotates along the second vertical shaft 44, it also drives the second vertical shaft 31 to rotate. A swing arm 21 rotates along the housing 10, thereby adjusting the initial angular position of the first swing arm 21 and the second swing arm 31. This facilitates the first swing arm 21 and the second swing arm 31 to be staggered during rotation, reducing the possibility of the first swing arm 21 and the second swing arm 31 rotating to the same side of the housing 10 at the same time, thus improving the dynamic balance and stability of the device. Furthermore, after the first swing arm 21 and the second swing arm 31 are staggered, the different orientations of the blowing assembly 22 and the sweeping plate 32 make it easier for the sweeping plate 32 to push the debris that the blowing assembly 22 has not yet blown away to the outside of the housing 10, further improving the convenience of removing debris from the road surface.

[0032] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a first sliding hole 55 is provided on the first swing arm 21, and a first sliding column 56 is fixedly connected to the end of the first rotating rod 51 away from the second vertical axis 44. The first sliding column 56 is slidably engaged with the first sliding hole 55, and the first sliding column 56 is rotatably engaged with the first sliding hole 55.

[0033] It should be noted that the first sliding hole 55 is preferably a strip-shaped hole in this invention, and the cross-sectional shape of the first sliding post 56 is preferably circular in this invention.

[0034] According to the above structure, during the process of the first rotating rod 51 driving the first swing arm 21 to swing back and forth along the housing 10, the first rotating rod 51 rotates along the second vertical axis 44 and drives the first sliding column 56 to rotate along the second vertical axis 44. This causes the first sliding column 56 to slide back and forth along the first sliding hole 55 while also rotating along the first sliding hole 55, thereby causing the rotating first rotating rod 51 to drive the first swing arm 21 to swing back and forth along the housing 10.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, one end of the second swing arm 31 is rotatably connected to the housing 10, and the other end of the second swing arm 31 is fixedly connected to the cleaning plate 32. A second rotating rod 61 is detachably installed on the second vertical shaft 44, and the end of the second rotating rod 61 is slidably connected to the second swing arm 31.

[0036] It should be noted that the end of the second rotating rod 61 is also rotatably connected to the second swing arm 31.

[0037] According to the above structure, after the second vertical shaft 44 rotates, it drives the second rotating rod 61 to rotate. While the end of the second rotating rod 61 slides along the second swing arm 31, the end of the second rotating rod 61 also rotates along the second swing arm 31, so that the second swing arm 31 swings back and forth along the housing 10. This causes the end of the second swing arm 31 to drive the cleaning plate 32 to swing back and forth in front of the housing 10, which facilitates the cleaning plate 32 to slide back and forth along the push plate 12. This makes it easier for the cleaning plate 32 to push the debris stuck in front of the push plate 12 to both sides of the housing 10, improving the convenience of cleaning debris.

[0038] like Figure 6 and Figure 7 As shown, the second rotating rod 61 is rotatably connected to the second vertical shaft 44. The second vertical shaft 44 is provided with a third limiting hole 62. The second rotating rod 61 is provided with a plurality of fourth limiting holes 63 at one end near the second vertical shaft 44. The plurality of fourth limiting holes 63 are distributed circumferentially around the axis of the second vertical shaft 44. The third limiting hole 62 and the fourth limiting hole 63 are slidably connected to the interior of the second limiting hole 62 and the fourth limiting hole 63.

[0039] It should be noted that the second rotating rod 61 and the second vertical shaft 44 are detachably connected together by the second limiting pin 64.

[0040] According to the above structure, when it is necessary to adjust the initial angular position between the first swing arm 21 and the second swing arm 31, the second limiting pin 64 is pulled out from inside the third limiting hole 62 and the fourth limiting hole 63, and the second rotating rod 61 is rotated along the second limiting pin 64 so that the third limiting hole 62 is aligned with the fourth limiting hole 63 in a suitable position. The second limiting pin 64 is then inserted into the third limiting hole 62 and the fourth limiting hole 63 to limit the second rotating rod 61 and the second vertical shaft 44, thereby adjusting the initial angular position between the second rotating rod 61 and the second vertical shaft 44. Since the second rotating rod 61 rotates along the second vertical axis 44, it also drives the second swing arm 31 to rotate along the housing 10, thereby adjusting the initial angle position of the first swing arm 21 and the second swing arm 31, so that the first swing arm 21 and the second swing arm 31 are staggered during rotation. Combined with the detachable connection between the first rotating rod 51 and the second vertical axis 44, it is convenient to adjust the initial angle position between the first rotating rod 51 and the second rotating rod 61, thereby facilitating further adjustment of the initial angle position between the first swing arm 21 and the second swing arm 31.

[0041] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a second sliding hole 65 is provided on the second swing arm 31, and a second sliding column 66 is fixedly connected to the end of the second rotating rod 61 away from the second vertical axis 44. The second sliding column 66 is slidably engaged with the second sliding hole 65, and the second sliding column 66 is rotatably engaged with the second sliding hole 65.

[0042] It should be noted that the second sliding hole 65 is preferably a strip-shaped hole in this invention, and the cross-sectional shape of the second sliding column 66 is preferably circular in this invention.

[0043] According to the above structure, during the process of the second rotating rod 61 driving the second swing arm 31 to swing back and forth along the housing 10, the second rotating rod 61 rotates along the second vertical axis 44 and drives the second sliding column 66 to rotate along the second vertical axis 44. This causes the second sliding column 66 to slide back and forth along the second sliding hole 65 while also rotating along the second sliding hole 65, thereby causing the rotating second rotating rod 61 to drive the second swing arm 31 to swing back and forth along the housing 10.

[0044] like Figure 4 and Figure 8 As shown, the push plate 12 has a groove 71 inside, and a slider 72 is fixedly connected to the cleaning plate 32. The slider 72 slides in the groove 71. The push plate 12 has a groove 73 on the outside, and a roller 74 is rotatably connected to the cleaning plate 32. The outside of the roller 74 rolls in the groove 73.

[0045] It should be noted that the cross-sectional shape of the slide groove 71 and the slider 72 is arc-shaped, and the center of the slide groove 71 and the slider 72 coincides with the center of the push plate 12. The cross-sectional shape of the groove 73 is arc-shaped, and the center of the groove 73 coincides with the center of the push plate 12.

[0046] According to the above structure, the sweeping plate 32 and the push plate 12 are slidably connected together by the slider 72. The roller 74 cooperates with the groove 73, making the process of the sweeping plate 32 sliding along the push plate 12 more stable. Since a part of the roller 74 extends into the inner side of the groove 73, it limits the sweeping plate 32 and the push plate 12 in the vertical direction, reducing the relative displacement between the sweeping plate 32 and the push plate 12 in the vertical direction, further making the process of the sweeping plate 32 sliding along the push plate 12 more stable.

[0047] like Figure 2 , Figure 3 and Figure 5 As shown, a cleaning roller 75 is provided on the outer side of the wheel 11. The cleaning roller 75 rolls with the outer surface of the wheel 11 and is rotatably connected to the housing 10.

[0048] It should be noted that the cleaning roller 75 is located on the bottom inner side of the housing 10, which is used to reduce the entry of dust and other impurities from the outside of the housing 10 into the interior of the housing 10 and contaminate the cleaning roller 75.

[0049] According to the above structure, as the wheel 11 rolls along the road surface, the wheel 11 rotates along the housing 10. The rotating wheel 11 drives the cleaning roller 75 to rotate along the housing 10, so that the cleaning roller 75 cleans the outer surface of the wheel 11, reducing the situation where impurities adhere to the outer surface of the wheel 11 and affect the normal rolling of the wheel 11 along the road surface, reducing the situation where impurities move with the wheel 11 to the position between the road surface and the wheel 11, causing the wheel 11 to shake and the device to bump, thus improving the stability of the device in detection. Moreover, the cleaning process is completed during the forward movement of the device, and there is no need to stop the forward movement and detection process of the device during cleaning.

[0050] The working principle of this invention is as follows: When the housing 10 moves forward, the wheel 11 rolls along the road surface. At this time, the wheel 11 and the housing 10 rotate relative to each other. After the wheel 11 rotates, it drives the first swing arm 21 and the second swing arm 31 to rotate along the housing 10. After the first swing arm 21 rotates, it drives the output end of the blower assembly 22 to swing back and forth in front of the housing 10's travel path, blowing away debris in the fan-shaped area of ​​the road surface at the front of the housing 10. Compared with the prior art, it is easier to expand the blowing range of the blower assembly 22. After the second swing arm 31 rotates, it drives the sweeping plate 32 to swing back and forth in front of the push plate 12, so that the sweeping plate 32 slides along the push plate 12 and cleans the impurities stuck in front of the push plate 12. This reduces the situation where debris is stuck in front of the push plate 12 and affects the push plate 12's subsequent pushing of other debris, and reduces the need for manual cleaning of debris on the push plate 12, thereby improving the convenience of cleaning debris.

[0051] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
