Description

Technical Field

[0001] This utility model relates to the technical field of road inspection, and in particular to a road surface thickness measurement and sampling device for engineering supervision. Background Technology

[0002] In road construction, pavement thickness is a crucial parameter. Whether it's cement or asphalt, pavement thickness has a decisive impact on the road's lifespan and performance. Therefore, during project supervision and acceptance, detailed measurements of pavement thickness, along with the materials used for paving, are essential.

[0003] For example, Chinese patent CN212513720U discloses an asphalt pavement thickness measuring device for engineering supervision. It includes a base plate and a support plate arranged parallel to the pavement, a transmission rod arranged perpendicular to the pavement on the lower surface of the support plate, a cylindrical drill cylinder fixedly mounted at the bottom end of the transmission rod, and multiple supports spaced circumferentially along the edge of the base plate. The support plate is located directly below the base plate. The top end of the transmission rod rotatably rests on the lower surface of the support plate. The bottom of the drill cylinder is open. The support plate has a driving component for rotating the transmission rod, and the base plate has a lifting component for raising and lowering the support plate. This device is used for sampling asphalt pavement.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Defect 1: When sampling cement pavement, a lot of dust is generated, which not only affects the observation of the pavement during drilling, but also affects human health due to the large amount of dust; Defect 2: During sampling, the drill bit generates high temperatures during the downward drilling process, which can easily damage the drill bit; Defect 3: After the pavement is sampled, potholes are left on the pavement, affecting the aesthetics and pavement integrity.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 The following is a further detailed description of this application: A road surface thickness measurement and sampling device for engineering supervision includes a base plate 1. A push rod 2 is fixedly installed on one side of the upper end of the base plate 1, and a set of symmetrically distributed columns 3 are provided on the upper end of the base plate 1. A drilling mechanism is installed between two columns 3, and the drilling mechanism is a press-type drilling structure that can be elastically raised and lowered. A dust cover 15 is movably installed inside the base plate 1 below the drilling mechanism, and a water spraying mechanism is provided inside the dust cover 15. A vacuum cleaner body 21 is provided above the base plate 1, and a vacuum head 22 is provided at the bottom of the base plate 1. The vacuum head 22 is connected to the vacuum cleaner body 21 through the vacuum pipe through the base plate 1. Self-locking wheels 24 are installed at the four corners of the bottom of the base plate 1. The press-drilling structure causes the dust cover 15 to move downwards simultaneously. This integrated drilling sampling, cleaning, backfilling and repair device improves the overall performance of the device and makes it more convenient to use.

[0026] Reference Figure 1 , Figure 3 , Figure 5 The drilling mechanism includes a motor 8, a handle 9 on top of the motor 8, and first connecting rods 7 connected to both sides of the motor 8. A rotating shaft 10 is connected to the output end of the motor 8, and a cylindrical drill bit 11 is mounted below the rotating shaft 10. Pressing the handle 9 causes the first connecting rods 7 to move downwards. The column 3 has an internal mounting groove 4, and a first spring 5 is installed inside the mounting groove 4. A first slider 6 is connected to the upper end of the first spring 5, and the first connecting rod 7 is inserted into the mounting groove 4 and fixedly connected to the first slider 6. The bottom end of the first spring 5 is provided with... The second slider 12 is provided with a second spring 13 in the mounting groove 4 at the bottom of the second slider 12. The second slider 12 is connected to one end of the second connecting rod 14, and the other end of the second connecting rod 14 is connected to the dust cover 15. The drilling structure moves the dust cover 15 through the second slider 12 and the second connecting rod 14. After the drilling is completed, the press-and-rebound drilling mechanism can automatically spring back to its original position after being released, which facilitates the removal of the sample from the cylindrical drill bit 11. At the same time, the synchronously raised and lowered dust cover 15 can protect and prevent dust from the area around the cylindrical drill bit 11.

[0027] Reference Figure 3 , Figure 4 The water spraying mechanism includes a water tank 18, which is mounted on the base plate 1. A water pump 19 is provided on one side of the water tank 18. The water pump 19 is connected to the water spraying ring 16 through a water pipe 20. The water spraying ring 16 is installed inside the dust cover 15 and has evenly distributed water spray nozzles 17. When the machine is started, the water spraying ring 16 is activated to spray water and reduce dust. A filling hopper 23 is provided on the base plate 1 on one side of the push rod 2. The bottom of the filling hopper 23 extends through the base plate 1 to below it. Spraying water onto the cylindrical drill bit 11 can further improve the dust prevention effect.

[0028] Working principle: When in use, the device is pushed to the work site by the push rod 2. When taking thickness samples, the motor 8 is started, and the handle 9 on the motor 8 is held and pressed down. The first connecting rods 7 on both sides of the motor 8 slide down inside the mounting groove 4 through the first slider 6. During the sliding process, the first slider 6 compresses the first spring 5. At the same time, under the pressure of the first spring 5, the second slider 12 also slides down along the mounting groove 4. During the sliding process, the second slider 12 compresses the second spring 13. During this process, the motor 8 drives the cylindrical drill bit 11 to rotate through the rotating shaft 10. When the pressure is pressed down until the cylindrical drill bit 11 contacts the ground, the pressure is continued until the drilling and sampling are completed.

[0029] During the downward pressing process, the second connecting rod 14 drives the dust cover 15 to move downward in sync until the bottom of the dust cover 15 touches the ground. At this time, the dust cover 15 just covers the outside of the cylindrical drill bit 11 for protection and dust prevention.

[0030] While drilling, the water pump 19 is started, and water is transported to the water spray ring 16 through the water pipe 20. Water is then sprayed onto the cylindrical drill bit 11 that is rotating through the water spray nozzle 17 on the water spray ring 16 to cool it down and reduce dust.

[0031] After drilling is completed, release the downward-pressing handle 9. Under the rebound force of the first spring 5 and the second spring 13, the motor 8 and the dust cover 15 will spring back to their initial positions, and the drill material in the drive cylinder drill bit 11 can be removed.

[0032] After drilling and sampling are completed, the vacuum cleaner body 21 is started and the base plate 1 is pushed back and forth. The dust suction head 22 at the bottom is used to clean the impurities on the ground. Finally, the base plate 1 is pushed so that the bottom of the filling hopper 23 is aligned with the drilled hole position after sampling. The mixed quick-drying cement is poured into the filling hopper 23 and flows into the drilled hole position to complete the backfilling and repair.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
