Before the construction of municipal roads, the ground layer needs to be drilled and sampled in advance to facilitate subsequent detection and other treatments. The road surface needs to be detected. The coring drilling device needs to be used in the detection process. In the coring construction process, the core body is often separated from the coring barrel, causing the core body to be retained in the hole. Therefore, the staff needs to be equipped with special tools to clamp the core body. The core body is also tightly attached to the coring barrel. Therefore, the staff needs to use a rubber hammer to knock the coring barrel. This will cause the staff to carry tools for movement, which is not convenient for work and will also reduce work efficiency.

[0028] Referring to Figures 1-7, a road drilling device for highway maintenance includes: a support frame 10, a right cover 11, a left cover 12, and a power mechanism 13. The right cover 11, left cover 12, and power mechanism 13 are assembled as a whole on the support frame 10. The support frame 10 is provided with a lifting rack 14, and the right cover 11 is provided with a lifting rotating rod 15. The lifting rack 14 and the lifting rotating rod 15 are meshed to control the vertical movement of the right cover 11, left cover 12, and power mechanism 13. The power mechanism 13 is assembled from a power motor, transmission gears, and transmission rods. The transmission rod of the power mechanism 13 is convex and downward. A rotating block 16 is fixed on the transmission rod of the power mechanism 13. A fixing member 17 is fixedly installed at the lower end of the rotating block 16. An installation groove 19 is opened on the periphery of the rotating block 16 and between the rotating block 16 and the fixing member 17. An installation bracket 21 is installed on the left cover 12 by a threaded part. The rotating block 16 and the installation bracket 21 are connected. Both ends of the rear side (front side position in Figure 3) are threaded parts installed between the left cover 12 and the two threaded parts are respectively installed vertically and threadedly connected to the lower end of the left cover 12, and installed horizontally and threadedly connected to the right end of the left cover 12. A transmission belt 18 is connected between two adjacent transmission wheels 20. A core tube 22 is installed at the mounting frame 21. The transmission wheel 20 abuts against the side wall of the mounting groove 19. The transmission wheel 20 is rotatably installed on the mounting frame 21. The core tube 22 and the transmission wheel 20 are connected by a key and rotate synchronously. A transmission mechanism is provided between the power mechanism 13 and the core tube 22 and at the mounting frame 21. The transmission mechanism includes a fixing part 17 fixed at the lower end of the rotating block 16.

[0029] The inner circumferential surface of the core-taking cylinder 22 is provided with a spiral groove 23. A brush ring 24 is fixed at the bottom of the support frame 10. A counterweight ring 25 is inserted into the bottom end of the brush ring 24. The inner circumferential surface of the brush ring 24 is provided with evenly distributed bristles that can abut against the outer circumferential surface of the core-taking cylinder 22. An adapter 26 is threadedly installed at the upper end of the core-taking cylinder 22. The adapter 26 is connected to an external water spray pipe. The left end and the lower end of the adapter 26 are provided with threaded connection ports. The threaded connection port at the lower end is threadedly connected to the core-taking cylinder 22, and a leak-proof ring is provided between the transmission wheel 20 and the core-taking cylinder 22 (both of the following two pipe connection parts are provided with leak-proof rings). The threaded connection port at the left end is connected to an external water spray pipe.

[0030] The adapter 26 also has an upward-opening connection port. A sealing mechanism 30 is provided at the upper connection port. The sealing mechanism 30 includes a guide sleeve. A leak-proof ring, a gasket, and a threaded fixing sleeve are provided on the outer periphery of the guide sleeve. A push rod 27 is slidably connected to the inner end of the guide sleeve. The push rod 27 extends upward and passes through the mounting bracket 21. A rotating disk is threaded onto the upper end of the push rod 27. A push plate 28 and a water tank 29 are fixedly installed on the lower end of the push rod 27. The water tank 29 is hollow, and its upper end has an upward-protruding cross-section with an arc surface. The lower end of the push plate 28 can abut against the core inside the core-collecting cylinder 22. The push plate 28 is located inside the core-collecting cylinder 22, and its radius is smaller than the inner diameter of the core-collecting cylinder 22. The radius of the water tank 29 is the same as the radius of the push plate 28. The lower end is provided with anti-slip texture to increase friction with the core. A vibrator is fixedly installed on the top of the push rod 27. The vibrator is a surface vibrator (such as a Netter vibrator VAC). Vibration and water flow lubrication reduce the push force exerted by the user on the push rod 27.

[0031] Working process or usage method:

[0032] 1. Position the support frame 10 in the working position. The bottom of the support frame 10 can be equipped with swivel casters and threaded support structure. Both the casters and support mechanism use common replacement parts available on the market. The casters allow the support frame 10 to move freely, while the threaded support mechanism increases friction and reduces the impact of uneven ground, keeping the bottom of the support frame 10 level.

[0033] 2. The user controls the vertical movement of the core sampling cylinder 22 via the lifting rack 14 and the lifting rod 15. The lifting rack 14 and lifting rod 15 in the diagram use a rack and pinion meshing method to achieve vertical movement. Alternatively, they can be replaced with a threaded screw and threaded slider method. By rotating the lifting rod 15, the gear rotates, and under the meshing of the rack, it drives the right cover 11 and left cover 12, which slide vertically with the support frame 10, to move (the right cover 11 and left cover 12 are installed on the upper part of the support frame 10 via threaded fittings, thus achieving vertical sliding engagement). This moves the core sampling cylinder 22 above the ground. At this time, the power mechanism 13 is switched on, energizing it to provide rotational power to the core sampling cylinder 22, allowing it to rotate and cut the ground for sampling.

[0034] 3. During the operation of the power mechanism 13, the power is transmitted to the transmission rod. Through the installation of the rotating block 16 and the transmission rod, the rotating block 16 rotates synchronously. Then, under the action of the transmission belt 18 and the transmission wheel 20, the rotational force is transmitted to another transmission wheel 20. The rotation of the core tube 22 is achieved through the key engagement between the transmission wheel 20 and the core tube 22.

[0035] 4. Before the core retrieval cylinder 22 is put into operation, a water spray pipe is installed at the left end of the connector 26. When the water pump is working, the water spray pipe will send water into the connector 26 and into the core retrieval cylinder 22 through the connection between the lower end of the connector 26 and the core retrieval cylinder 22. The top of the connector 26 is sealed by the sealing mechanism 30, so that the core retrieval cylinder 22 can be used for lubrication and cooling by water.

[0036] 5. After core retrieval is completed, the core retrieval cylinder 22 is moved upward. The groove 23 of the core retrieval cylinder 22 increases the friction between the core and the core, ensuring that the core is brought into the opening by the core retrieval cylinder 22. Then, the user pushes the push rod 27 downward. The push rod 27 moves downward in sliding cooperation with the sealing mechanism 30, thereby pushing the push plate 28 downward to abut against the core surface. By rotating, the push plate 28 can be rotated. Thus, by pushing downward and rotating, the push plate 28 is moved to separate the core from the core retrieval cylinder 22. The water guide tank 29 is used to guide the water flow as it flows into the core retrieval cylinder 22, reducing the pushing force of the water flow on the push plate 28, thereby reducing the impact of the push plate 28 on the core retrieval process.
