Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0020] A road construction and maintenance device includes an installation box 1. On one side of the installation box 1, a hanging rack 2 is connected, which can adjust its height. On the other side of the installation box 1, a grinding structure 5 for grinding the guardrail is connected through a connecting frame 4. On one side of the grinding structure 5, a height detection structure 6 that contacts the top of the guardrail is installed. On the other side of the grinding structure 5, a dust collection structure for collecting the dust generated by grinding is installed. By installing the hanging rack 2 on the side of the carriage, then starting the vehicle and controlling the operation of the electric push rod inside the hanging rack 2 at the same time, the grinding roller 20 is made to correspond to the corrugated guardrail. At the same time, the roller 33 inside the height detection structure 6 is made to contact the top of the corrugated guardrail, and the measurement data of the tensile and compressive force sensor 32 at this time is recorded, which is recorded as the reference plane. Then the grinding structure 5 is made to work, and at the same time the vehicle first moves towards the corrugated guardrail, making the grinding roller 20 inside the grinding structure 5 closely adhere to the corrugated guardrail. Then the vehicle slowly moves along the road, and at the same time it is ensured that the roller 33 always rolls on the corrugated guardrail. Thus, the roller 33 can move up and down with the undulation of the corrugated guardrail, so that the measurement data of the tensile and compressive force sensor 32 changes. The tensile and compressive force sensor 32 sends the measured data to the electric control box 3. The electric control box 3 compares the measured data with the initial data, thereby controlling the telescopic movement of the electric push rod 9, so that the grinding roller 20 can always closely adhere to the corrugated guardrail, thus ensuring the stable and smooth progress of grinding.

[0021] A chute 8 is opened inside the hanging rack 2. At the position corresponding to the chute 8 on the side of the installation box 1, a slider 7 is installed. The top of the slider 7 is connected to the top of the chute 8 through an electric push rod 9. An electric control box 3 is installed at the top of the hanging rack 2. A fixing hole 10 is opened on the hanging rack 2, and a fixing column 11 is threadedly connected inside the fixing hole 10. By controlling the operation of the electric push rod 9, the slider 7 can be driven to move up and down, thereby facilitating the adjustment of the height of the installation box 1, and thus driving the grinding roller 20 to move up and down.

[0022] The connecting frame 4 includes a top plate 12 and a bottom plate 13 distributed up and down. Slide rods 14 are installed on the sides of the top plate 12 and the bottom plate 13. A sleeve 15 is installed inside the installation box 1. The top of the slide rod 14 is arranged inside the sleeve 15 and is connected with a stop head 16. A first spring 17 is sleeved outside the slide rod 14 inside the sleeve 15. Under the combined action of the slide rod 14 and the first spring 17, the grinding roller 20 can always closely adhere to the surface of the corrugated guardrail, thus facilitating the grinding operation. At the same time, it is ensured that as long as the distance between the vehicle and the corrugated guardrail is within the set interval, the grinding roller 20 can always be in close contact with the corrugated guard plate. The setting of the distance interval between the vehicle and the corrugated guardrail is mainly determined by the deformation amount of the first spring 17 and the length of the slide rod 14 inside the sleeve 15.

[0023] The grinding structure 5 includes a bearing seat 18 and a motor 25. The motor 25 is installed at the bottom end of the top plate 12, and the bearing seat 18 is installed on the surface of the bottom plate 13. A mounting shaft 19 is connected to the output shaft of the motor 25 through a coupling. The bottom end of the mounting shaft 19 is arranged inside the bearing seat 18. A tray 21 is installed on the side of the mounting shaft 19. A grinding roller 20 is sleeved outside the mounting shaft 19 above the tray 21. A limiting column 22 passing through the inside of the grinding roller 20 is installed on the surface of the tray 21. A pressure plate 23 slidably connected to the limiting column 22 is sleeved outside the mounting shaft 19. A limiting nut 24 is threadedly connected to the outside of the limiting column 22 above the pressure plate 23. When the motor 25 works, it drives the mounting shaft 19 to rotate, thereby driving the grinding roller 20 to rotate, so as to perform the grinding operation. The specification of the grinding roller 20 needs to be selected according to the specification of the corrugated guard plate to be ground.

[0024] The height detection structure 6 includes a mounting frame 26 installed on one side of the top plate 12. Inside the mounting frame 26, a U-shaped frame 28 capable of sliding up and down is connected through a guide block 27. A limiting nut 29 is threadedly connected to the U-shaped frame 28 above the guide block 27. A limiting disk 30 is installed on the side of the U-shaped frame 28 below the U-shaped frame 28. A pull-pressure sensor 32 sleeved outside the U-shaped frame 28 is installed at the bottom end of the mounting frame 26. A second spring 31 sleeved outside the U-shaped frame 28 is installed at the bottom end of the pull-pressure sensor 32. Thus, the roller 33 can move along with the undulation of the corrugated guard plate, so that the measurement data of the pull-pressure sensor 32 changes. According to the industrial computer inside the electric control box 3, calculations are made to obtain the distance that the grinding roller 20 needs to move, and then the work of the electric push rod 9 is controlled to move the grinding roller 20 up and down.

[0025] The dust collection structure includes a main pipe 34 installed on the other side of the top plate 12. The bottom end of the main pipe 34 is distributed with extraction pipes 35. An air inlet is opened on the surface of the main pipe 34 corresponding to the grinding structure 5. The main pipe 34 is connected to an air extractor through a hose, and a filter box is arranged between the air extractor and the main pipe 34. Thus, it is convenient to collect the dust generated by grinding and reduces the pollution to the environment.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
