Description

Technical Field

[0001] This invention relates to the field of road construction technology, and in particular to a device for measuring the smoothness of construction pavement that can be cleaned. Background Technology

[0002] After road construction is completed, in order to avoid problems during subsequent vehicle traffic, people will measure the smoothness of the completed road surface. Therefore, a measuring device needs to be designed.

[0003] Patent application CN214308571U discloses a construction road surface flatness measuring device that can clean the bottom surface. An external tractor pulls a lever, causing the drive wheel to rotate, which in turn moves the base platform, allowing the flatness measuring instrument to move and measure the road surface. A servo motor is activated, causing a conveyor belt to rotate around a fixed rod and the output end of the servo motor, which in turn rotates a brush to clean the construction road surface to be measured. A blower is then activated, blowing air from the inlet pipe through the outlet pipe and finally through the dust removal pipe onto the construction road surface. This measuring device measures the road surface using the flatness measuring instrument, while the brush and blower clean impurities. However, when the external tractor comes into contact with stones, it is difficult to remove them, which can easily lead to wear on the bottom of the external tractor. Simultaneously, the continued measurement by the flatness measuring instrument results in inaccurate values.

[0004] We have designed a construction pavement flatness measuring device that can be cleaned to ensure accurate measurement results, thereby overcoming the difficulty of ensuring accurate measurement results when using existing measuring devices. Summary of the Invention

Detailed Implementation

[0064] The present invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0065] Example 1

[0066] A construction pavement smoothness measuring device that can clean the ground, now referenced. Figure 1 and Figure 2 It includes a measuring vehicle 1, a detector 2, a blower 3, a protective locking mechanism 4, and a cleaning mechanism 5. The measuring vehicle 1 is equipped with a detector 2, the right side of the measuring vehicle 1 is equipped with a protective locking mechanism 4, the lower right side of the measuring vehicle 1 is equipped with two blowers 3, and the protective locking mechanism 4 is equipped with a cleaning mechanism 5.

[0067] For reference Figure 1 , Figure 3 and Figure 4 The protective locking mechanism 4 includes a movable frame 41, a protective plate 42, a pressure spring 43, a locking block 44, and a limiting wheel 45. The movable frame 41 is slidably connected to the front and rear sides of the right side of the measuring vehicle 1. The protective plate 42 is welded to the right side of the two movable frames 41. The pressure spring 43 is connected between the two movable frames 41 and the measuring vehicle 1. The pressure spring 43 is wound around the movable frame 41. The locking block 44 is welded to the left side of the two movable frames 41. The limiting wheel 45 is connected to the front and rear sides of the right side of the measuring vehicle 1. After the locking block 44 moves, it contacts the limiting wheel 45. The movement of the measuring vehicle 1 drives the movable frame 41 and the protective plate 42 to move. The protective plate 42 contacts the stone. The protective plate 42 and the movable frame 41 move to the left. The locking block 44 moves to the left and contacts the limiting wheel 45. The pressure spring 43 is compressed.

[0068] For reference Figure 1 and Figure 5The cleaning mechanism 5 includes a connecting frame 51, a ground wheel 52, a gear set 53, and a cleaning rod 54. The connecting frame 51 is welded to the outside of the two moving frames 41. The ground wheel 52 is rotatably connected to the two connecting frames 51. The cleaning rod 54 is rotatably connected between the two connecting frames 51. The gear set 53 is connected between the two ground wheels 52 and the cleaning rod 54. The gear set 53 consists of two spur gears. Spur gears are connected to the front and rear sides of the cleaning rod 54. Spur gears are connected to the inner sides of the two ground wheels 52. The two spur gears on the front side mesh, and the two spur gears on the rear side mesh. When the moving frame 41 moves, it drives the connecting frame 51 and the ground wheel 52 to move. The ground wheel 52 rotates when it contacts the ground. The gear set 53 and the cleaning rod 54 rotate.

[0069] When it is necessary to measure the smoothness of a road surface, this construction road surface smoothness measuring device that can clean the surface can be used. First, the measuring vehicle 1 is moved to a suitable position. Then, the detector 2 and blower 3 are turned on. The movement of the measuring vehicle 1 moves the detector 2 and blower 3, and the limit wheel 45 rotates. The detector 2 moves to measure the smoothness of the road surface. During the movement of the blower 3, impurities on the road surface are blown away. At the same time, the movement of the measuring vehicle 1 moves the sweeping rod 54, the protective plate 42, and the grounding wheel 52. The grounding wheel 52 rotates during its movement, which in turn causes the gear set 53 and the sweeping rod 54 to rotate. The rotation of the sweeping rod 54 sweeps away the impurities, improving the accuracy of the measurement. During the movement of the protective plate 42, the impurities are pushed outwards. When the right side of the protective plate 42 comes into contact with the stone, the protective plate 42 and the moving frame 41 move adaptively to the left, the connecting frame 51 and the cleaning rod 54 move to the left, causing the locking block 44 to move to the left and lock the limiting wheel 45. The pressure spring 43 is compressed, the measuring vehicle 1 stops moving, and people can move the stone away, thus achieving the effect of prompting and avoiding the stone from affecting the measurement. When the stone is away from the protective plate 42, the pressure spring 43 resets and drives the moving frame 41 and the protective plate 42 to move to the right, the connecting frame 51 and the cleaning rod 54 to move to the right, and then the locking block 44 moves to the right away from the limiting wheel 45. The measuring vehicle 1 continues to move. When the measurement is completed, people turn off the measuring vehicle 1, the detector 2 and the blower 3, and place the construction road surface flatness measuring device, which can clean the ground, in a suitable position.

[0070] Example 2

[0071] Based on Example 1, now refer to Figure 1 , Figure 6 and Figure 7It also includes a clearing mechanism 6, which includes a rack 61, a missing gear 62, a pull rope 63, a slider 64, a clearing rod 65, a guide rod 66, a return spring 67, and a tension spring 68. The rack 61 is slidably connected to the right side of the measuring vehicle 1. The missing gear 62 is welded to the clearing rod 54, and the rack 61 meshes with the missing gear 62. A tension spring 68 is connected between the rack 61 and the measuring vehicle 1, and the tension spring 68 is wound around the measuring vehicle 1. Guide rods 66 are welded inside both protective plates 42, and sliders are slidably connected to both guide rods 66. 64. A pull rope 63 is connected between the slider 64 and the rack 61. The pull rope 63 passes through the protective plate 42. A return spring 67 is connected between the slider 64 and the protective plate 42. The return spring 67 is wound around the guide rod 66. A clearing rod 65 is connected to both sliders 64. The rotation of the clearing rod 54 drives the missing gear 62 to rotate. The missing gear 62 meshes with the rack 61. The missing gear 62 drives the rack 61 to move to the left, and the tension spring 68 is compressed. The pull rope 63 pulls the slider 64 to move inward. The clearing rod 65 moves inward, and the return spring 67 is stretched.

[0072] For reference Figure 1 and Figure 8 It also includes a flushing mechanism 7, which includes a support frame 71, high-pressure nozzles 72, a water distributor 73, a water pipe 74, a water tank 75, and a switch 76. A water tank 75 is welded to the right side of the measuring vehicle 1. Switches 76 are installed on both the front and rear sides of the measuring vehicle 1. After the moving frame 41 moves, the switch 76 is pressed. A water distributor 73 is connected to each of the two protective plates 42. A water pipe 74 is connected between each of the two water distributors 73 and the water tank 75. A support frame 71 is welded to the right side of each of the two protective plates 42. Four high-pressure nozzles 72 are evenly installed on each of the two support frames 71. The switch 76 is electrically connected to the high-pressure nozzles 72. The high-pressure nozzles 72 are connected to the water distributors 73. There are eight high-pressure nozzles 72. When the moving frame 41 moves to the left and presses the switch 76, the high-pressure nozzles 72 are activated. The water in the water tank 75 flows through the water pipes 74 and the water distributors 73 to the high-pressure nozzles 72, and the high-pressure nozzles 72 spray water onto the road surface.

[0073] For reference Figure 1 , Figure 9 and Figure 10 It also includes a blocking mechanism 8, which includes a wedge block 81, a lower pressure plate 82, a limiting rod 83, and a return spring 84. The measuring vehicle 1 has wedge blocks 81 welded to both the front and rear sides of the right side. Two limiting rods 83 are connected to the left side of each of the two protective plates 42. There are four limiting rods 83. The lower pressure plate 82 is slidably connected between the four limiting rods 83. After the lower pressure plate 82 moves, it contacts the wedge block 81. The lower pressure plate 82 is V-shaped. The lower pressure plate 84 is connected between the limiting rod 83 and the lower pressure plate 82. The return spring 84 is wrapped around the limiting rod 83. There are four return springs 84.

[0074] For reference Figure 1 , Figure 11 and Figure 12 It also includes a side protection mechanism 9, which includes a connecting block 91, a protective cloth 92 and a counterweight 93. The measuring vehicle 1 has connecting blocks 91 welded on both the front and rear sides, and protective cloth 92 is wrapped around both connecting blocks 91. The counterweight 93 is connected to the lower side of both protective cloths 92.

[0075] The rotation of the cleaning rod 54 drives the missing gear 62 to rotate. When the missing gear 62 meshes with the rack 61, the missing gear 62 drives the rack 61 to move to the left, and the tension spring 68 is compressed, which causes the pull rope 63 to pull the slider 64 to move inward. The return spring 67 is stretched, which causes the clearing rod 65 to move inward. When the missing gear 62 does not mesh with the rack 61, the tension spring 68 returns to its original position, which drives the rack 61 to move to the right. Then, the return spring 67 returns to its original position, which drives the slider 64 to move outward. The clearing rod 65 moves outward, and the impurities stuck on the protective plate 42 by the moving clearing rod 65 are cleaned up, thus achieving the cleaning effect and preventing impurities from remaining on the protective plate 42.

[0076] First, people inject an appropriate amount of water into the water tank 75. When the moving frame 41 moves to the left and contacts the switch 76, the high-pressure nozzle 72 is activated, so that the water in the water tank 75 flows through the water pipe 74 and the water distributor 73 to the high-pressure nozzle 72. The high-pressure nozzle 72 sprays water onto the road surface to wash away the impurities, thus achieving the washing effect. When the moving frame 41 moves to the right away from the switch 76, the high-pressure nozzle 72 is closed.

[0077] When the protective plate 42 moves to the left, it causes the lower pressure plate 82 to move to the left. When the lower pressure plate 82, which moves to the left, comes into contact with the wedge block 81, the lower pressure plate 82 moves downward accordingly, thereby stretching the reset spring 84. The downward-moving lower pressure plate 82 blocks the sewage to the right side of the protective plate 42, thus achieving the blocking effect and preventing the sewage flow from affecting the measurement. When the protective plate 42 moves to the right, it causes the lower pressure plate 82 to move to the right. When the lower pressure plate 82 moves to the right away from the wedge block 81, the reset spring 84 resets, causing the wedge block 81 to move upward and reset.

[0078] Before starting the measuring vehicle 1, people manually pull down the counterweight 93 to release the protective cloth 92. After the counterweight 93 moves and contacts the ground, people release the counterweight 93. Then, people start the measuring vehicle 1. The movement of the measuring vehicle 1 moves the counterweight 93 and the protective cloth 92. The protective cloth 92 blocks external impurities to prevent them from affecting the movement of the measuring vehicle 1. When the measuring vehicle 1 is no longer needed to move, people manually move the counterweight 93 upward. The protective cloth 92 is then rolled up. When the counterweight 93 moves upward and is blocked by the connecting block 91, people release the counterweight 93.

[0079] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
