[0015] Beneficial technical effects of the present invention: 1. The road and bridge joint level measuring device according to the present invention includes a motor. When the motor starts, it drives the rotating rod to rotate. When the rotating rod rotates, it drives the first gear to rotate. Since the first gear is meshed with the first rack, the first gear can drive the first support plate to rise when it rotates. At the same time as the first support plate rises, it can drive the level measuring instrument to rise, so that the level measuring instrument can be moved out of the protective box for measurement. When not in use, the level measuring instrument can be moved into the protective box. When the level measuring instrument is moved into the protective box, the protective box and the protective cover cooperate with each other to store and protect the level measuring instrument that has been moved into the protective box, so that the level measuring instrument is not easily damaged by external collisions during transportation.

[0016] 2. When the motor drives the rotating rod to rotate, the rotating rod can drive the first gear to rotate. Since the first gear is meshed with the first rack, the first gear can drive the first support plate to rise when it rotates. At the same time, the first support plate can drive another first gear to rotate. The rotation of the two first gears can drive the two second gears to rotate. Since the rotation directions of the two second gears are different, the rotation of the second gear can drive the second rack to move, thereby moving the support plate out of the protective box. This can improve the stability when using the level measuring instrument. By moving the support plate out of the protective box, the force-bearing area of ​​the device can be increased, thereby improving the stability of the level measuring instrument during use. This makes it less likely for the level measuring instrument to tip over and affect the detection values. Attached Figure Description

Detailed Implementation

[0019] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0020] like Figures 1-11As shown, the road and bridge joint level measuring device provided in this embodiment includes a protective assembly for housing and protecting the level measuring device; a rotating assembly for driving the level measuring assembly and the stabilizing assembly to move; a first transmission assembly for moving the level measuring assembly and moving the level measuring device into the protective assembly for housing and protection; a second transmission assembly for driving the stabilizing assembly to move; a stabilizing assembly for improving the stability of the level measuring device; a guiding assembly for guiding and limiting the stabilizing assembly; a level measuring assembly for measuring the level of road and bridge joints; and a moving assembly for guiding and limiting the level measuring assembly.A cleaning assembly is used to clean the leveling assembly. A protective assembly includes a protective box 1, a protective cover 11, and sliding holes 12. The protective box 1 has multiple sliding holes 12. The protective cover 11 is installed on the top of the leveling assembly. A rotating assembly includes a motor 2, a motor frame 21, and a side column 22. The side column 22 is installed on the protective box 1, and the motor frame 21 is installed at one end of the side column 22. The motor 2 is installed on the motor frame 21. A first transmission assembly includes a rotating rod 3, a first gear 31, and a first rack 32. Multiple rotating rods 3 are rotatably mounted on the protective box 1. The output end of the motor 2 is connected to one of the rotating rods 3. The first gear 31 is installed on the rotating rod 3. The bottom of the leveling assembly... The first rack 32, which meshes with the first gear 31, is installed in the first part of the horizontal measuring assembly. The horizontal measuring assembly includes a first support plate 7, a support leg 71, a support frame 72, and a horizontal measuring instrument 73. The top of the first rack 32 is connected to the bottom of the first support plate 7. The support leg 71 is installed on the first support plate 7. The support frame 72 is installed at one end of the support leg 71. The horizontal measuring instrument 73 is installed on the support frame 72. The top of the horizontal measuring instrument 73 is equipped with a protective cover 11. The moving assembly includes a moving rod 8, a moving ring 81, a moving block 82, and a support rod 83. The moving rod 8 is installed on the protective box 1. The support rod 83 is installed on one side of the first support plate 7. The moving block 82 is installed at one end of the support rod 83. 2. A movable ring 81 is installed on the movable block 82, which is slidably connected to the movable rod 8. A second support plate 84 is installed on the movable rod 8. By setting up a motor 2, the motor 2 starts and drives the rotating rod 3 to rotate. When the rotating rod 3 rotates, it can drive the first gear 31 to rotate. Since the first gear 31 is meshed with the first rack 32, the first gear 31 can drive the first support plate 7 to rise when it rotates. At the same time as the first support plate 7 rises, it can drive the level measuring instrument 73 to rise, so that the level measuring instrument 73 can be moved out of the protective box 1 for measurement. And when not in use, the level measuring instrument 73 can be moved back into the protective box 1. When the level measuring instrument 73 is moved back into the protective box 1... When the protective case 1 and the protective cover 11 cooperate with each other, they can store and protect the level measuring instrument 73 that has been moved into the protective case 1, preventing the level measuring instrument 73 from being damaged by external impacts during transport. The motor frame 21 and the side column 22 cooperate with each other to easily support the motor 2. The support leg 71 and the support frame 72 cooperate with each other to easily support the level measuring instrument 73. The sliding connection between the moving ring 81 and the moving rod 8 facilitates the guiding and limiting of the level measuring instrument 73. The rotating rod 3 is rotatably connected to the protective case 1 via a bearing, and the supporting rod 83 supports the moving ring 81.

[0021] In this embodiment, as Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 Figure 9 Figure 10 and Figure 11 As shown, the second transmission assembly includes a second rack 4, a second gear 41, and a base rod 42. The second gear 41 is mounted on the rotating rod 3, and the base rod 42 is mounted on the stabilizing assembly. One end of the base rod 42 is connected to the second gear 41. The stabilizing assembly includes a support plate 5 and a connecting rod 51. Multiple support plates 5 are slidably arranged inside the protective box 1. Two adjacent support plates 5 are connected by a connecting rod 51. The base rod 42 is mounted on one side of the support plate 5. The guiding assembly includes a guide rod 6, a guide ring 61, a connecting block 62, and a connecting column 63. The guide rod 6 is mounted on the protective box 1, and the guide ring 61 is slidably mounted on the guide rod 6. The connecting block 62 is mounted on the guide ring 61, and one end of the connecting block 62 is connected to the support plate 5. When the motor 2 drives the rotating rod 3 to rotate, the rotating rod 3 can drive the first gear 31 to rotate. Because the first gear 31 is meshed with the first rack 32, the first gear 31 can rotate. When one gear 31 rotates, it can drive the first support plate 7 to rise. While the first support plate 7 rises, it can drive another first gear 31 to rotate. When the two first gears 31 rotate, they can drive the two second gears 41 to rotate. Since the two second gears 41 rotate in different directions, the second gears 41 can drive the second rack 4 to move when they rotate, thereby moving the support plate 5 out of the protective box 1. This can improve the stability when using the level measuring instrument 73. Since moving the support plate 5 out of the protective box 1 can increase the force-bearing area of ​​the device, it can improve the stability of the level measuring instrument 73 during use, making it less likely for the level measuring instrument 73 to tip over and affect the detection value. By setting the bottom rod 42, it is easy to support the second rack 4. By setting the guide ring 61 and the guide rod 6 to slide, it is easy to guide and limit the support plate 5.

[0022] In this embodiment, as Figure 2 and Figure 3 As shown, the cleaning assembly includes support columns 9 and cleaning brushes 91. Multiple support columns 9 are installed on the protective box 1, and a cleaning brush 91 is installed at one end of each support column 9. By setting the cleaning brush 91, when the motor 2 drives the rotating rod 3 to rotate, the rotating rod 3 can drive the first gear 31 to rotate. Since the first gear 31 is meshed with the first rack 32, the first gear 31 can drive the first support plate 7 to rise when it rotates. When the first support plate 7 rises, it drives the level measuring instrument 73 to move. When the level measuring instrument 73 passes the cleaning brush 91, the cleaning brush 91 can clean the dust and impurities on the level measuring instrument 73, so that the dust and impurities will not easily affect the measurement effect of the level measuring instrument 73.

[0023] In this embodiment, as Figures 1-11 As shown in the figure, the working process of the road and bridge joint level measuring device provided in this embodiment is as follows: Step 1: The motor 2 starts and drives the rotating rod 3 to rotate. When the rotating rod 3 rotates, it drives the first gear 31 to rotate. When the first gear 31 rotates, it drives the first rack 32 to move, which in turn drives the first support plate 7 to rise. When the first support plate 7 rises, it drives the level measuring instrument 73 to rise. The level measuring instrument 73 is then moved out of the protective box 1 for measurement. Step 2: When the motor 2 drives the rotating rod 3 to rotate, the rotating rod 3 drives the first gear 31 to rotate. When the first gear 31 rotates, it drives the first support plate 7 to rise. When the first support plate 7 rises, it drives the other first gear 31 to rotate. At the same time, the rotation of the two first gears 31 drives the two second gears 41 to rotate. When the second gears 41 rotate, they drive the second rack 4 to move, thereby moving the support plate 5 out of the protective box 1, thus improving stability when using the level measuring instrument 73. Step 3: When the motor 2 drives the rotating rod 3 to rotate, the rotating rod 3 drives the first gear 31 to rotate. When the first gear 31 rotates, it drives the first support plate 7 to rise. When the first support plate 7 rises, it drives the level measuring instrument 73 to move. When the level measuring instrument 73 passes the cleaning brush 91, the cleaning brush 91 can clean the dust and impurities on the level measuring instrument 73.

[0024] In summary, in this embodiment, the road bridge joint level measuring device, by setting up a motor 2, drives the rotating rod 3 to rotate when the motor 2 starts. When the rotating rod 3 rotates, it can drive the first gear 31 to rotate. Since the first gear 31 is meshed with the first rack 32, the first gear 31 can drive the first support plate 7 to rise when it rotates. At the same time as the first support plate 7 rises, it can drive the level measuring instrument 73 to rise, so that the level measuring instrument 73 can be moved out of the protective box 1 for measurement. And when not in use, the level measuring instrument 73 can be moved into the protective box 1. When the level measuring instrument 73 is moved into the protective box 1, the protective box 1 and the protective cover 11 cooperate with each other to measure the level of the moving instrument. The protective case 1 houses and protects the level measuring instrument 73, preventing damage from external impacts during transport. The motor frame 21 and side column 22 work together to support the motor 2, and the support leg 71 and support frame 72 work together to support the level measuring instrument 73. The sliding connection between the moving ring 81 and the moving rod 8 facilitates guiding and limiting the level measuring instrument 73. The rotating rod 3 is rotatably connected to the protective case 1 via a bearing. The support rod 83 supports the moving ring 81. When the motor 2 drives the rotating rod 3 to rotate, the rotating rod 3 drives the first gear 31 to rotate. Because the first gear 31 and the first… The racks 32 are meshed together. When the first gear 31 rotates, it can drive the first support plate 7 to rise. Simultaneously, the first support plate 7 drives another first gear 31 to rotate. The rotation of the two first gears 31 simultaneously drives the two second gears 41 to rotate. Since the two second gears 41 rotate in different directions, their rotation can drive the second rack 4 to move, thereby moving the support plate 5 out of the protective box 1. This improves the stability of the level measuring instrument 73 during use. Moving the support plate 5 out of the protective box 1 increases the force-bearing area of ​​the device, further enhancing the stability of the level measuring instrument 73 during use. The system is designed to prevent tipping and ensure accurate measurement. The base rod 42 provides support for the second rack 4, and the guide ring 61, slidably connected to the guide rod 6, facilitates the guiding and limiting of the support plate 5. When the motor 2 drives the rotating rod 3 to rotate, the rotating rod 3 drives the first gear 31 to rotate. Because the first gear 31 meshes with the first rack 32, its rotation causes the first support plate 7 to rise. As the first support plate 7 rises, it moves the level measuring instrument 73. When the level measuring instrument 73 passes the cleaning brush 91, the cleaning brush 91 cleans the dust and impurities on the level measuring instrument 73, preventing dust and impurities from affecting the measurement results.
