Description

Technical Field

[0001] This application relates to the field of borehole sampling device technology, and more specifically, to a road inspection borehole sampling device. Background Technology

[0002] After a certain period of use, concrete pavements will develop cracks and damage, greatly affecting passing vehicles. Core sampling is one of the important methods for assessing the quality of concrete pavements. By analyzing the samples and measuring their physical and mechanical properties such as density, the quality of the concrete pavement can be evaluated. A sampling device for construction engineering quality, disclosed in patent CN219694580U, uses a fixing ring installed at the bottom of a connecting rod. A nozzle installed at the bottom of the fixing ring is connected to a water pump via a connecting pipe. During sampling, the surface of the sampling cylinder can be rinsed, effectively reducing the risk of damage during the rotating sampling process. The generated dust also cools the surface of the sampling tube. Three support frames, rotatably connected in the side groove of the fixed box, provide horizontal support to the fixed box during sampling, ensuring the stability of the sampling tube's rotation. Regarding the aforementioned related technologies, the inventor believes the following drawbacks still exist: The drilling sampling device in the comparative literature requires operators to carry and move it, resulting in high labor intensity during multi-point sampling operations. Furthermore, the drill bit cannot be cooled effectively during drilling, easily causing damage, and generating stone splashes and a large amount of dust. Therefore, we propose a road inspection drilling sampling device. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a road inspection drilling and sampling device, which solves the technical problems of the drilling and sampling devices in the prior art, which require operators to carry and move them, resulting in high labor intensity during multi-point sampling operations, and the inability to cool the drill bit during drilling, which easily causes damage to the drill bit, as well as the generation of stones and a large amount of dust. The present application achieves this by installing four self-locking universal wheels on the base plate for easy movement, and using the self-locking property to achieve stable drilling. By manually rotating the drive wheel, the gear rotates along the toothed plate, which drives the slide and U-shaped seat to slide up and down along the toothed plate through the drive shaft. This allows the electric drill to drive the sampling drill cylinder to rotate at high speed and move up and down stably, achieving safe drilling and sampling work on the road surface. The stones splashed during drilling are blocked by the protective ring to protect the sampling personnel. In addition, the water in the bucket, under its own weight, reaches the water spray head through the flexible tube to cool the sampling drill cylinder and reduce the generation of dust.

[0005] 2. Technical Solution

[0006] This application provides a road inspection drilling and sampling device, comprising: a base plate, with self-locking casters rotatably mounted at each of the four corners of the base plate's bottom surface; a C-shaped ring, a protective ring, and a toothed plate fixedly mounted on the base plate; a water bucket inserted into the C-shaped ring; a water outlet pipe fixedly connected to the bottom of the water bucket; a flexible tube threadedly connected to the water outlet pipe; the end of the flexible tube located at the protective ring and threadedly connected to a water spray head; a toothed plate fixedly connected to the bottom of the base plate; and a lifting mechanism mounted on the toothed plate, the lifting mechanism including a gear meshing with the toothed plate. The gear is fixedly connected to a drive shaft, and a slide is rotatably connected to each end of the drive shaft. The slides are slidably connected to the gear plate. A U-shaped seat is threaded between the slides. The drive shaft is rotatably connected to the U-shaped seat, and the gear is rotatably located in the U-shaped groove of the U-shaped seat. An electric drill is fixedly connected to the U-shaped seat. A sampling drill barrel is detachably installed at the output end of the electric drill. A screw is threaded through one of the slides. An L-shaped anti-slip block is rotatably connected to the end of the screw. The screw rotates along the corresponding slide, and the L-shaped anti-slip block tightly presses against the surface of the gear plate.

[0007] By adopting the above technical solution, four self-locking casters are rotatably installed on the base plate, which can be easily moved along the road. When moved to the designated sampling position, the self-locking casters can be used to stabilize the entire sampling device on the ground. Then, the screw is manually turned to disengage the L-shaped anti-slip block from the toothed plate. Then, the drive shaft is manually turned to make the gear rotate along the toothed plate. This drives the two slide blocks to slide vertically along the toothed plate. The slide blocks can move the U-shaped seat, thus the electric drill drives the sampling drill barrel to rotate at high speed. It can move up and down with the U-shaped seat to realize the drilling and sampling operation on the road surface. During drilling, stones may be splashed. The protective ring can block the splashed stones and protect the sampling personnel. In addition, the water bucket installed on the base plate through the C-shaped ring limiter allows water to flow out through the water outlet pipe, flexible pipe and water nozzle under the influence of the water's own weight. This can realize the water injection and cooling treatment of the sampling drill barrel, effectively cooling the sampling drill barrel and reducing the generation of dust.

[0008] Optionally, a circular groove is provided on the base plate, and a protective ring is fixedly connected to the base plate at the circular groove.

[0009] By adopting the above technical solution, the circular groove is set at the bottom of the sampling drill cylinder, so that the sampling drill cylinder can move down along the circular groove to realize road drilling treatment.

[0010] Optionally, a water filling cap is threaded onto the upper end of the bucket, a regulating valve is rotatably mounted on the flexible tube, and a T-shaped seat is fixedly fitted onto the end of the flexible tube near the spray head. The T-shaped seat is threadedly mounted on the base plate with bolts.

[0011] By adopting the above technical solution, the water in the bucket flows into the flexible pipe due to its own weight. The flow rate can be adjusted by regulating the valve, and the opening and closing function can be realized.

[0012] Optionally, both sides of the toothed plate are provided with convex guide grooves, the toothed plate is slidably mounted with a slide block through the convex guide grooves, and a push handle is fixedly provided on the toothed plate.

[0013] By adopting the above technical solution, the toothed plate can be easily moved as a whole by setting a push handle, making it convenient to use.

[0014] Optionally, a drive wheel is fixedly provided at one end of the drive shaft, and multiple screws are threadedly connected between the slide and the U-shaped seat.

[0015] By adopting the above technical solution, the drive shaft can be easily rotated manually by setting a drive wheel, and the slide and the U-shaped seat are connected for limiting, so they can move up and down together.

[0016] 3. Beneficial effects

[0017] One or more technical solutions provided in this application have at least the following technical effects or advantages: The device is equipped with four self-locking casters on the base plate, which facilitates displacement. The self-locking property can be used to achieve stable drilling. By manually rotating the drive wheel, the gear rotates along the toothed plate. The drive shaft drives the slide and U-shaped seat to slide up and down along the toothed plate, thereby driving the electric drill to rotate the sampling drill cylinder at high speed and achieve stable up and down displacement, realizing safe drilling and sampling work on the road surface. The stones splashed during drilling are blocked by the protective ring to protect the sampling personnel. Under the weight of the water in the bucket, the water reaches the water spray head through the flexible pipe, which can cool the sampling drill cylinder and reduce the generation of dust.
