Description

Technical Field

[0001] This invention relates to the field of borehole sampling for quality testing in highway engineering, specifically to a borehole sampling device and method for quality testing in highway engineering. Background Technology

[0002] After highway construction, highway supervisors need to inspect the construction quality. Inspection items include pavement smoothness, permeability, roughness, and whether the thickness meets standards. Quality inspection plays a crucial role in ensuring the quality of highway construction, improving road use quality, and maximizing investment efficiency. When inspecting the thickness of the road surface, first, a circle is drawn on the road surface with chalk. Then, the core drill bit on the highway core drilling machine is aligned with this circle, and a hole is drilled. Since the core drill bit is hollow, a highway sample will appear inside the hole. The core drilling machine is then restarted, and the core drill bit is lifted. Due to the weight of the highway sample, it remains inside the road surface. A metal clamp is then used to remove the highway sample from inside the road surface for measurement.

[0003] Existing road surface quality testing devices generate significant frictional heat after the core drill bit enters the road surface, due to prolonged contact and friction between the drill bit and the road surface. Current technology uses water flushing for heat dissipation. After removing the road sample, the water in the pothole needs to be wiped dry for subsequent cement filling. However, the drying method involves manually absorbing the water with towels or other items. Therefore, a new drilling and sampling device for road surface quality testing is needed that can promptly remove the road sample after drilling and quickly absorb the water from the pothole.

[0015] A drilling method based on a drilling and sampling device for highway engineering quality inspection includes the following steps:

[0016] Step 1: Push the moving device to the location marked for drilling samples on the road by pushing the handle. Then, turn the handwheel to rotate the first lead screw downwards to limit the moving seat. Next, start the first electric push rod to move the movable sleeve downwards and move the sliding plate to the right through the limiting wedge block. Then, move the moving plate backwards to expose the downward channel. Then, start the motor to drive the gear to rotate. The rotation of the gear drives the drill barrel to rotate through the gear ring to drill holes in the road surface.

[0017] Step 2: After drilling is completed, the second electric push rod is activated to move the clamping assembly downwards while the first electric push rod is activated to move the drill cylinder upwards, moving the lower end of the drill cylinder above the road surface. Then, the clamping assembly moves out of the drill cylinder and contacts the road sample. After that, it rolls on the surface of the road sample and opens up to move into the gap between the outer surface of the road sample and the road, and is clamped inwards by the second spring. Then, the first electric push rod is activated to move the drill cylinder downwards while the second electric push rod is activated simultaneously to keep the clamping assembly stationary relative to the road surface, thereby clamping the clamping plate inwards by the inclined block. Then, the first electric push rod is activated to move the drill cylinder upwards, moving the road sample upwards.

[0018] Step 3: After moving to the corresponding position of the sliding plate, the sliding plate moves to the left, simultaneously moving the moving plate to the bottom of the road sample. Then, the second electric push rod is activated to move downwards, moving the clamping plate out of the lower end of the drill cylinder to release the restriction on the road sample. The road sample falls onto the moving plate by its own weight. Then, the first electric push rod is activated to move the limiting inclined block upwards. Through the sliding groove set inside the sliding plate, the sliding plate is moved forward so that the box reaches the pit position. At the same time, the moving plate also sends out the road sample on it for easy retrieval.

[0019] Step 4: Manually rotate the adjustment handle to drive the worm gear to rotate, which in turn drives the second lead screw to rotate. The rotation of the second lead screw causes the first sliding block to move downward to adjust the depth of the counterweight in the pothole. Then, start the water pump to suck away the water in the pothole. Next, rotate the adjustment assembly in the opposite direction to bring the counterweight out into the housing. Then, start the first electric push rod to drive the limit block to move downward back to its original position, thereby driving the moving plate to move back to its original position.

[0045] The first spring 604 is designed to prevent the sliding plate 602 from sliding excessively. The sliding plate 602 has grooves that correspond to the upper and lower inclined surfaces of the limiting inclined block 803, which are used to move the sliding plate 602.

[0046] The drilling device 8 includes a fixed frame 801, a movable sleeve 802, a limiting wedge block 803, a motor 804, a gear 805, a gear ring 806, a drill barrel 807, a second electric push rod 808, and a clamping assembly 809.

The movable sleeve 802 is slidably connected to the inner surface of the support 2 by the slide bars provided on both sides.

[0047] When the drill barrel 807 rotates, the clamping component 809 inside will not rotate.

[0048] The motor 804 is fixedly connected to the inner surface of the movable housing 802. The gear 805 is fixed to the output end of the motor 804. The gear ring 806 is fixedly connected to the side surface of the drill barrel 807 and located on the inner surface of the movable housing 802. The gear 805 meshes with the gear ring 806. The drill barrel 807 is slidably connected to the inner surface of the movable housing 802 through the gear ring 806. The upper end of the second electric push rod 808 is fixedly connected to the lower surface of the fixed frame 801.

[0049] The clamping assembly 809 includes a pushing circular plate 80901, a clamping plate 80902, an inclined block 80903, a rotating rod 80904, a second spring 80905, and a fixing plate 80906. The pushing circular plate 80901 is fixedly connected to the output end of the second electric push rod 808. The upper end of the clamping plate 80902 is movably connected to the inner edge of the pushing circular plate 80901.

[0050] The inner side of the clamping plate 80902 is made of anti-slip material to prevent the road sample from slipping out during clamping. The clamping assembly 809 moves out of the drill cylinder 807 and contacts the road sample. Then, it rolls on the surface of the road sample and opens up to move into the gap between the outer surface of the road sample and the road by the rotating rod 80904. It is clamped inward by the second spring 80905. Then, the first electric push rod 7 is activated to drive the drill cylinder 807 to move downward and the second electric push rod 808 is activated at the same time to keep the clamping assembly 809 stationary relative to the road surface. Thus, the clamping plate 80902 is clamped inward by the inclined block 80903. Then, the first electric push rod 7 is activated to move the drill cylinder 807 upward, which drives the road sample to move upward.

[0051] The moving device 3 includes a limiting block 301, a first lead screw 302, a handwheel 303, and a universal wheel 304.

The handwheel 303 is fixedly connected to the upper surface of the first lead screw 302. The universal wheel 304 is movably connected to the lower surface of the limiting block 301.

[0052] A drilling method based on a drilling and sampling device for highway engineering quality inspection includes the following steps:

[0053] Step 1: Push the moving device 3 to the position marked for drilling samples on the road by pushing the handle 9. Then, turn the handwheel 303 to drive the first lead screw 302 to rotate downwards, thereby limiting the moving seat 1. Then, start the first electric push rod 7 to drive the movable sleeve 802 to move downwards, and drive the sliding plate 602 to move to the right through the limiting inclined block 803, thereby driving the moving plate 5 to move backwards to expose the downward channel. Then, start the motor 804 to drive the gear 805 to rotate. The rotation of the gear 805 drives the drill barrel 807 to rotate through the gear ring 806 to drill holes in the road surface.

[0054] Step 2: After drilling is completed, the second electric push rod 808 is activated to move the clamping assembly 809 downwards, while the first electric push rod 7 is activated to move the drill cylinder 807 upwards, moving the lower end of the drill cylinder 807 above the road surface. Then, the clamping assembly 809 moves out of the drill cylinder 807 and contacts the road sample. After that, the rotating rod 80904 rolls on the surface of the road sample and opens to move into the gap between the outer surface of the road sample and the road, and is clamped inwards by the second spring 80905. Then, the first electric push rod 7 is activated to move the drill cylinder 807 downwards, while the second electric push rod 808 is activated simultaneously to keep the clamping assembly 809 stationary relative to the road surface, thereby clamping the clamping plate 80902 inwards by the inclined block 80903. Then, the first electric push rod 7 is activated to move the drill cylinder 807 upwards, moving the road sample upwards.

[0055] Step 3: After moving to the corresponding position of the sliding plate 602, the sliding plate 602 moves to the left, simultaneously driving the moving plate 5 to move below the road sample. Then, the second electric push rod 808 is activated to move downwards, moving the clamping plate 80902 out of the lower end of the drill cylinder 807 to release the restriction on the road sample. The road sample falls onto the moving plate 5 by its own weight. Then, the first electric push rod 7 is activated to drive the limiting inclined block 803 to move upwards. Through the sliding groove set inside the sliding plate 602, the sliding plate 602 is moved forward so that the box 404 reaches the pit position. At the same time, the moving plate 5 also sends out the road sample on it for easy retrieval.

[0056] Step 4: Manually rotate the adjusting handle 40601 to drive the worm gear 40602 to rotate, which in turn drives the second lead screw 408 to rotate through the worm wheel 40603. The rotation of the second lead screw 408 causes the first sliding block 407 to move downward to adjust the depth of the counterweight block 405 in the road pothole. Then, start the water pump 401 to suck away the water in the pothole. Next, rotate the adjusting assembly 406 in the opposite direction to bring the counterweight block 405 out into the housing 404. Then, start the first electric push rod 7 to drive the limit inclined block 803 to move downward back to its original position, thereby driving the moving plate 5 to move back to its original position.

9. The drilling method based on the drilling and sampling device for highway engineering quality inspection according to any one of claims 1-8, characterized in that: Includes the following steps: Step 1: Push the moving device (3) to the position marked for drilling samples on the road by pushing the handle (9). Then turn the handwheel (303) to drive the first lead screw (302) to rotate downwards and limit the moving seat (1). Then start the first electric push rod (7) to drive the movable sleeve (802) to move downwards, and drive the sliding plate (602) to move to the right through the limiting inclined block (803), thereby driving the moving plate (5) to move backwards to expose the downward channel. Then start the motor (804) to drive the gear (805) to rotate. The rotation of the gear (805) drives the drill barrel (807) to rotate through the gear ring (806) to drill holes in the road surface. Step 2: After drilling is completed, the second electric push rod (808) is activated to drive the clamping assembly (809) to move downwards, while the first electric push rod (7) is activated to drive the drill cylinder (807) to move upwards, moving the lower end of the drill cylinder (807) above the road surface. Then, the clamping assembly (809) moves out of the drill cylinder (807) and contacts the road sample. Then, the rotating rod (80904) rolls on the surface of the road sample and opens to move into the gap between the outer surface of the road sample and the road, and is clamped inwards by the second spring (80905). Then, the first electric push rod (7) is activated to drive the drill cylinder (807) to move downwards, while the second electric push rod (808) is activated simultaneously to keep the clamping assembly (809) stationary relative to the road surface, so that the clamping plate (80902) is clamped inwards by the inclined block (80903). Then, the first electric push rod (7) is activated to move the drill cylinder (807) upwards, driving the road sample upwards. Step 3: After moving to the corresponding position of the sliding plate (602), the sliding plate (602) moves to the left, simultaneously driving the moving plate (5) to move below the road sample. Then, the second electric push rod (808) is activated to move downwards, moving the clamping plate (80902) out of the lower end of the drill cylinder (807) to release the restriction on the road sample. The road sample falls onto the moving plate (5) by its own weight. Then, the first electric push rod (7) is activated to drive the limiting inclined block (803) to move upwards. Through the sliding groove set inside the sliding plate (602), the sliding plate (602) is moved forward so that the box (404) reaches the pit position. At the same time, the moving plate (5) also sends out the road sample on it for easy picking. Step 4: Manually rotate the adjusting handle (40601) to drive the worm gear (40602) to rotate, and drive the second lead screw (408) to rotate through the worm wheel (40603). The rotation of the second lead screw (408) drives the first sliding block (407) to move downward to adjust the depth of the counterweight block (405) in the road pothole. Then, start the water pump (401) to suck away the water in the pothole. Then, rotate the adjusting assembly (406) in the opposite direction to bring the counterweight block (405) out into the housing (404). Then, start the first electric push rod (7) to drive the limit inclined block (803) to move downward back to its original position, thereby driving the moving plate (5) to move back to its original position.
