Abstract

This utility model discloses a drilling device for thickness detection in highway engineering. In use, rotating the first lead screw via the handle drives the cross brace to move downwards under the guidance of the second portal frame. The cross brace, along with the first portal frame fixed at both ends, moves downwards under the guidance of the base plate, bringing the base plate into contact with the highway surface and securing the device. The output of the first motor drives the second lead screw to rotate, which in turn drives the lifting plate, guided by the guide rod, to move downwards. The lifting plate, along with the mounting plate, moves downwards, and the mounting plate, along with the rotatably connected drill cylinder, moves downwards. After the bottom end of the drill cylinder penetrates into the cover, the output of the second motor drives the drill cylinder to rotate, bringing the bottom end of the drill cylinder through a through hole into contact with the highway surface, thus drilling the highway. Simultaneously, a water pump operates, delivering water from the storage tank to the annular pipe and spraying it onto the drilling site through a nozzle. The cover, in conjunction with the drilling device, prevents dust from escaping.

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.

[0018] Please see Figures 1-3 In this embodiment of the present invention, a drilling device for thickness detection in highway engineering includes a base plate 2. Universal wheels 1 are fixedly installed at the four corners of the bottom of the base plate 2. A water tank 4 and a water pump 5 are fixedly installed on the top of the base plate 2. A water inlet is provided on the top of the water tank 4, and a bucket lid is threaded onto the water inlet. The input end of the water pump 5 is connected to the output end of the water tank 4, and a valve is installed on the output end of the water tank 4. A base plate 6 is provided at the bottom of the base plate 2, and a lifting mechanism is provided on the base plate 2. The movable end of the lifting mechanism passes through the base plate 2 and is fixedly connected to the top of the base plate 6. An opening 13 is provided on the base plate 2, and a driving mechanism 14 is provided inside the opening 13. The bottom end of the driving mechanism 14 is fixedly installed on the top of the base plate 6, and the driving end at the top of the driving mechanism 14 is fixedly installed... A first motor 15 is provided. A mounting plate 16 is fixedly installed on the lifting end of the drive mechanism 14. A second motor 18 is fixedly installed on the top of the mounting plate 16. A drill cylinder 17 is rotatably connected to the bottom of the mounting plate 16. The output end of the second motor 18 passes through the mounting plate 16 and is fixedly connected to the top of the drill cylinder 17. A perforation 19 is provided below the drill cylinder 17 on the bottom plate 6. A cover 20 is fixedly installed at the perforation 19 on the top of the bottom plate 6. The drill cylinder 17 passes through the top of the cover 20 and slides and rubs against the cover 20. An annular pipe 21 is fixedly installed at the top of the cover 20. The interface of the annular pipe 21 passes through the top of the cover 20. The output end of the water pump 5 is connected to the interface of the annular pipe 21 through a water pipe. Spray nozzles 22 are evenly arranged around the bottom of the annular pipe 21.

[0019] During use, the lifting mechanism drives the base plate 6 to contact the ground. The output of the first motor 15 drives the drive mechanism 14 to work. The movable end of the drive mechanism 14, through the mounting plate 16, carries the bottom end of the drill cylinder 17 through into the cover 20. The output of the second motor 18 drives the drill cylinder 17 to rotate. The bottom end of the drill cylinder 17 passes through the through hole 19 and contacts the road surface, thus drilling the road. At the same time, the water pump 5 works, transporting water from the water tank 4 to the annular pipe 21 and spraying it onto the drilling site through the nozzle 22. This, together with the cover 20, prevents dust from escaping. Conversely, the drive mechanism 14 carries the drill cylinder 17 back to the initial position.

[0020] The drive mechanism 14 includes two guide rods 23 and a second lead screw 24. The bottom ends of the guide rods 23 are fixedly installed on the top of the base plate 6, and a top plate 26 is fixedly installed on the top of the guide rods 23. The second lead screw 24 is disposed between the guide rods 23, and both ends of the second lead screw 24 are rotatably connected to the top of the base plate 6 and the top plate 26. The top end of the second lead screw 24 passes through the top plate 26 and is fixedly connected to the output end of the first motor 15 fixedly installed on the top of the top plate 26. A lifting plate 25 is slidably connected to the guide rods 23, and the second lead screw 24 passes through the lifting plate 25 and is threadedly connected to the lifting plate 25. The lifting plate 25 is fixedly connected to the mounting plate 16. In use, the output end of the first motor 15 drives the second lead screw 24 to rotate, and the second lead screw 24 drives the lifting plate 25, guided by the guide rods 23, to move downward. The lifting plate 25 moves downward with the mounting plate 16, and the mounting plate 16 moves downward with the rotatably connected drill barrel 17. Conversely, it moves upward with the drill barrel 17.

[0021] The lifting mechanism includes a second portal frame 10, which is fixedly installed on the top of the base plate 2. A cross brace 9 slides through both ends of the second portal frame 10, and a first portal frame 8 is fixedly connected to both ends of the cross brace 9. The first portal frame 8 slides through both ends of the base plate 2 and is fixedly connected to the top of the base plate 6. A first lead screw 11 is provided inside the second portal frame 10. The two ends of the first lead screw 11 are rotatably connected to the base plate 2 and the second portal frame 10, respectively. The first lead screw 11 passes through the cross brace 9 and is threadedly connected to the cross brace 9. A handle 12 is fixedly connected to the top of the first portal frame 8 through the top of the first lead screw 11. In use, the first lead screw 11 is rotated through the handle 12, driving the cross brace 9 to move downwards under the guidance of the second portal frame 10. The cross brace 9, along with the first portal frame 8 fixedly connected at both ends, moves downwards under the guidance of the base plate 2, causing the base plate 6 to contact the road surface, thus fixing the device. Simultaneously, it moves the drive mechanism 14 downwards, causing the top of the base plate 6 to fit against the bottom of the base plate 2.

[0022] A rubber pad 7 is fixedly connected to the bottom of the base plate 6, and a perforation 19 passes through the rubber pad 7. The rubber pad 7 facilitates full contact between the base plate 6 and the road surface, while avoiding rigid contact between the base plate 6 and the road surface, which helps protect the road surface.

[0023] A push rod 3 is fixedly installed on the top of the base plate 2. Users can move the device by using the push rod 3 in conjunction with the casters 1 installed at the bottom of the base plate 2.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
