Description

Technical Field

[0001] This utility model relates to the field of highway testing technology, specifically a concrete testing device for highway engineering. Background Technology

[0002] In highway construction, the smoothness of concrete pavement is one of the important indicators for measuring the quality of pavement construction. Uneven pavement not only affects driving comfort, but also accelerates tire wear and may even lead to traffic safety hazards.

[0003] In existing technology, a marker pen is installed at the bottom of a moving plate and its position is adjusted to a suitable height. When the plate is moved on a flat surface, the marks are shallow. When the surface is uneven, the marker pen will leave marks of different color depths, thus determining the flatness of the surface.

[0004] However, in actual use, since most roads are made of cement or asphalt, the marker pens are easily damaged during road inspection, requiring frequent replacement by staff, which increases costs and causes waste. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete testing device for highway engineering. It solves the problem that in actual use, since most road surfaces are made of cement or asphalt, the marker pens are easily damaged during road surface testing, requiring frequent replacements by staff, which increases costs and causes waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete testing device for highway engineering, comprising a movable plate, a push rod fixedly connected to the rear top of the movable plate, a level fixedly connected to both sides of the top of the movable plate, a fixed base fixedly connected to the top of the movable plate, an installation column fixedly connected to the top of the fixed base, a roller provided below the movable plate, an insertion column installed above the roller, the outer wall of the insertion column being inserted into the inner wall of the fixed base and extending to one side of the top of the fixed base, penetrating the installation column.

[0007] Preferably, the outer wall of the roller is rotatably connected to a bracket, the top of the bracket is fixedly connected to a limiting plate, the top of the limiting plate is fixedly connected to the bottom of the insertion post, and the outer wall of the insertion post is sleeved with a spring, which abuts against the limiting plate and the fixed seat.

[0008] Preferably, a limiting post is inserted into the inner wall of the limiting plate, and the top of the limiting post is fixedly connected to the top of the inner wall of the fixing seat.

[0009] Preferably, the outer wall of the roller is provided with tuning forks at equal intervals in a ring. A plug is fixedly connected to the outer wall of the tuning fork. The outer wall of the plug is threadedly connected to the inner wall of the roller. A baffle is provided above the tuning fork. The outer wall of the baffle is inserted into the inner wall of the movable plate. A screw is pressed against one side of the baffle extending into the interior of the fixed seat. The outer wall of the screw is threadedly connected to the inner wall of the fixed seat.

[0010] Preferably, a mounting bracket is fixedly connected to the outer wall of the mounting column, a bracket is fixedly connected to the outer wall of the mounting bracket, a transparent tube is inserted into the inner wall of the bracket, and a connecting tube is threaded to the bottom of the transparent tube.

[0011] Beneficial effects

[0012] This utility model provides a concrete testing device for highway engineering. It has the following advantages: This concrete testing device, through the cooperation of a level, rollers, and a marker post, allows the marker post to move up and down inside the mounting post during road surface testing. By observing the scale on the outer wall of the marker post, the smoothness of the road surface can be judged. This solves the problem that most road surfaces are made of cement or asphalt, and during road surface testing, the marker pen is easily damaged, requiring frequent replacements by staff, thus increasing costs and causing waste.

[0013] By using a combination of a tuning fork, a baffle, and a support, when inspecting a road surface with poor smoothness, the roller will drive the tuning fork to impact the baffle. This will indicate to the staff that the road surface is relatively smooth, thus solving the problem of inaccurate inspection when staff are inspecting areas with large differences in elevation on the road surface.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In actual use, since most roads are made of cement or asphalt, the marker pens are easily damaged during road inspection, requiring frequent replacement by staff, which increases costs and causes waste.

[0021] In view of this, the present invention provides a concrete testing device for highway engineering, which solves the problem that in actual use, since most road surfaces are made of cement or asphalt, the marker pen is easily damaged during road surface testing, requiring frequent replacement by staff, which leads to increased costs and waste.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 It is known that a concrete testing device for highway engineering includes a movable plate 1, a push rod 3 fixedly connected to the top rear side of the movable plate 1, a level 2 fixedly connected to both sides of the top of the movable plate 1, a fixed base 14 fixedly connected to the top of the movable plate 1, an installation column 4 fixedly connected to the top of the fixed base 14, a roller 5 provided below the movable plate 1, an insertion column 7 installed above the roller 5, the outer wall of the insertion column 7 being inserted into the inner wall of the fixed base 14, and extending to one side of the top of the fixed base 14 through the installation column 4;

[0024] In the specific implementation process, it is worth noting that the level instrument 2 is installed on the top of the moving plate 1, and the installation direction of the level instrument 2 is different. This can make the position between the device and the ground level. When the push rod 3 is used to push the detection device to move, the roller 5 will move on the ground. When the road surface elevation difference changes, the roller 5 will drive the insertion column 7 to rise and fall inside the mounting column 4. At the same time, the outer wall of the insertion column 7 is set with scale. By observing the length of the insertion column 7 extending inside the mounting column 4, the elevation difference of the road surface can be determined. At the same time, the inner wall of the mounting column 4 is set with a sliding groove, and the outer wall of the insertion column 7 is set with a slider to ensure the stability of the insertion column 7 when it moves inside the mounting column 4.

[0025] Furthermore, a bracket 15 is rotatably connected to the outer wall of the roller 5, a limiting plate 9 is fixedly connected to the top of the bracket 15, the top of the limiting plate 9 is fixedly connected to the bottom of the insertion post 7, and a spring 8 is sleeved on the outer wall of the insertion post 7, with the spring 8 pressing against the limiting plate 9 and the fixed seat 14.

[0026] In the specific implementation process, it is worth noting that the support of the bracket 15 and the limiting plate 9 supports the roller 5, ensuring the stability of the roller 5 when moving. Under the compression of the spring 8, the bracket 15 drives the roller 5 to better press against the road surface, thereby ensuring the accuracy of the roller 5 when detecting the flatness of the road surface.

[0027] Furthermore, a limiting post 17 is inserted into the inner wall of the limiting plate 9, and the top of the limiting post 17 is fixedly connected to the top of the inner wall of the fixing base 14.

[0028] In the specific implementation process, it is worth noting that when the limiting plate 9 moves with the insertion post 7, the limiting plate 9 will move on the outer wall of the limiting post 17, which can ensure the stability of the limiting plate 9 when it is raised and lowered.

[0029] Example 2: From Figure 1-4 It can be seen that the outer wall of the roller 5 is provided with tuning forks 6 at equal intervals in a ring. The outer wall of the tuning fork 6 is fixedly connected with the insert block 16. The outer wall of the insert block 16 is threadedly connected to the inner wall of the roller 5. A baffle 18 is provided above the tuning fork 6. The outer wall of the baffle 18 is inserted into the inner wall of the moving plate 1. The baffle 18 extends to one side inside the fixed seat 14 and abuts against the screw 19. The outer wall of the screw 19 is threadedly connected to the inner wall of the fixed seat 14.

[0030] In the specific implementation process, it is worth noting that the tuning fork 6 is installed in a ring on the outer wall of the roller 5 and fixed to the outer wall of the roller 5 by the insert block 16. The position of the baffle 18 is adjusted by the screw 19. In this way, when the roller 5 rotates and encounters a position with a large road surface drop, the tuning fork 6 will hit the outer wall of the baffle 18, thereby making the tuning fork 6 make a sound and letting the staff know.

[0031] Furthermore, a mounting bracket 10 is fixedly connected to the outer wall of the mounting column 4, a bracket 11 is fixedly connected to the outer wall of the mounting bracket 10, a transparent tube 12 is inserted into the inner wall of the bracket 11, and a connecting tube 13 is threaded to the bottom of the transparent tube 12.

[0032] In the specific implementation process, it is worth noting that the outer wall of the transparent tube 12 is provided with graduations, and the inner wall of the bracket 11 is provided with a cavity, which allows the transparent tube 12 to be inserted into it and fixed to the outer wall of the mounting bracket 10. The bottom of the transparent tube 12 is provided with threads, which allows the connecting tube 13 to be screwed into the bottom of the transparent tube 12. When detecting the height of the two ends of the road surface, the two devices are placed on both sides of the road, and the transparent tubes 12 of the two devices are connected together by a connecting tube 13. The smoothness of the road surface and the height difference between the two points of the road surface are judged by observing the liquid level in the transparent tubes 12 on both sides.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
