Description

Technical Field

[0001] This invention belongs to the field of road inspection technology, and specifically relates to a road inspection drilling and core sampling device. Background Technology

[0002] After road construction is completed, quality testing is usually required, including testing the concrete and asphalt layers poured on the road. Before testing, core samples need to be taken from the poured concrete and asphalt layers. The obtained core samples are then taken back to the laboratory for testing. Therefore, when drilling core samples from the road, a road core drilling device is required for operation and sampling.

[0003] However, existing road drilling core sampling devices use water to cool and lubricate the core drum during drilling, resulting in the continuous generation of mud and water. Since these devices lack suction capabilities, the mud and water generated during drilling flows freely onto the road, polluting the road surface. Furthermore, once the mud and water dry, it generates a lot of dust due to wind, further polluting the surrounding environment. Summary of the Invention

[0004] In view of the problems mentioned in the background art above, the present invention provides a road inspection drilling core sampling device to solve the problem that the existing road drilling core sampling devices do not have a dirt suction function, which causes the mud and water generated during drilling to flow randomly on the road, thereby polluting the road surface. Moreover, after the mud and water dries, it will generate a lot of dust under the influence of wind, thus polluting the surrounding environment.

[0005] The technical solution adopted in this invention is as follows:

[0016] Furthermore, the enclosure assembly includes a screw cylinder, which is disposed at the top center of the base plate. The inner cavity of the screw cylinder penetrates the base plate. The outer peripheral wall of the screw cylinder is threaded, and the inner peripheral wall is smooth. A retaining cylinder is fitted into the inner cavity of the screw cylinder. Two opposing limiting grooves are provided on the screw cylinder, and two opposing limiting blocks are provided on the outer peripheral wall of the retaining cylinder. A threaded ring is threaded onto the outer peripheral wall of the screw cylinder, and an annular groove is provided on the inner peripheral wall of the bottom of the threaded ring. The limiting blocks are fitted into the limiting groove and the annular groove.

[0017] A storage sleeve is provided at the bottom center of the base plate, a rubber ring is provided at the bottom of the surrounding cylinder, an annular cavity is provided inside the rubber ring, an upper abutment plate is provided on the top wall of the annular cavity, a lower abutment plate is provided on the bottom wall of the annular cavity, and a spring is provided between the upper abutment plate and the lower abutment plate.

[0018] Furthermore, the lifting frame includes a support frame, on which a screw is vertically mounted, and a motor is mounted on the top of the support frame. The drive shaft of the motor is connected to the top of the screw. An assembly plate is fitted together on the support frame and the screw, and a mounting seat and a mounting seat are mounted on the assembly plate.

[0019] Furthermore, the core drilling assembly includes a second motor and a hollow rotating rod. The second motor is mounted on a mounting base, and the hollow rotating rod is rotatably locked inside the assembly plate. A pulley is mounted on the drive shaft of the second motor, and a pulley is mounted on the top of the hollow rotating rod. The pulley is connected to the pulley via a transmission belt, and a core-taking drum is mounted on the bottom of the hollow rotating rod.

[0020] Furthermore, the top edge of the core-taking drum is provided with an installation groove, and a clamping plate is installed in the installation groove. A fixing cylinder is provided in the side wall of the installation groove near the center of the core-taking drum. A stop spring and a stop post are provided in the fixing cylinder. The stop spring is located between the bottom of the fixing cylinder and the stop post. A screw is screwed into the outer peripheral wall of the core-taking drum located at the installation groove.

[0022] Furthermore, the sludge suction assembly includes a water pump, which is mounted on a mounting frame. The water pump has a suction pipe on its suction pipe, one end of which penetrates the bottom circumferential side wall of the casing and extends into the inner cavity of the casing. The water pump has a discharge pipe on its discharge pipe, with the outlet of the discharge pipe facing the sewage chamber.

[0023] The beneficial effects of this invention are:

[0024] 1. Using a combination of a traveling vehicle, storage unit, lifting frame, core drilling assembly, water pumping assembly, enclosure assembly, and sludge pumping assembly, the traveling vehicle moves the device to the corresponding location on the road. Then, the enclosure assembly is adjusted and lowered so that its bottom is firmly against the road. The lifting frame then moves the core drilling assembly lower, allowing it to drill into the road. During the drilling process, the water pumping assembly draws clean water from the storage unit and sprays it into the core drilling assembly to cool and lubricate it. The mud and water generated during drilling are contained by the enclosure assembly to prevent them from flowing out. Simultaneously, the sludge pumping assembly extracts the mud and water contained by the enclosure assembly and pumps it into the sludge chamber of the storage unit for temporary storage.

[0025] 2. Through the combination of the mounting slot, clamping plate, fixing cylinder, abutment spring, abutment column and screw, when the core drilling assembly's core drilling drum is in place, the screw is rotated to make its screw-in end abut against the clamping plate, causing the clamping plate to move closer to the center of the core drilling drum, so as to clamp the sample core's peripheral wall inside the core drilling drum and prevent the sample core from falling out of the core drilling drum when it is lifted upwards.

[0037] like Figures 1 to 8 As shown, a road inspection drilling core sampling device includes:

[0038] The traveling vehicle includes a base plate 101, with traveling wheels 102 at each of the four corners of the bottom of the base plate 101. A handle 103 is provided at the front of the base plate 101, which can drive the traveling wheels 102 to roll by pulling the handle 103, so that the base plate 101 can move. A placement frame 104 is provided at the back of the base plate 101, and auxiliary traveling wheels 105 are provided at the bottom of the support legs of the placement frame 104. The auxiliary traveling wheels 105 can provide auxiliary support for the placement frame 104.

[0039] Stabilizing components are provided on both opposite sides of the base plate 101. The stabilizing components include threaded sleeves 201, which are fixedly installed inside the base plate 101. A stud 202 is screwed into the threaded sleeve 201. A handwheel 203 is provided on the top of the stud 202, and a support plate 204 is rotatably fitted on the bottom of the stud 202. By rotating the handwheel 203, the stud 202 can be rotated and moved up and down inside the threaded sleeve 201, so that the support plate 204 can move up and down. A limit post 205 is provided on the top of the support plate 204. The limit post 205 passes through the base plate 101 and can limit the support plate 204 to prevent it from rotating along with the stud 202.

[0040] When the pull handle 103 drives the traveling wheel 102 to roll, moving the device to the corresponding position on the road, the handwheel 203 is turned to drive the stud 202 to rotate and move downward in the screw sleeve 201, causing the support plate 204 to move downward and support the road, thus supporting the entire device, causing the traveling wheel 102 to disengage from the road, thereby preventing the entire device from moving and stabilizing the device at the corresponding position on the road.

[0041] See Figure 1 , Figure 2 and Figure 7 The vehicle has a storage unit on its back, including a storage tank 401, which is mounted on a shelf 104. The storage tank 401 contains a wastewater chamber 402 and a clean water chamber 403. The wastewater chamber 402 is located above the clean water chamber 403. A water inlet pipe 404 is vertically installed at one corner of the top of the clean water chamber 403. The top opening of the water inlet pipe 404 extends through the wastewater chamber 402 to the top of the storage tank 401, allowing for easy addition of clean water to the clean water chamber 403. A cleaning pipe 405 is provided on the side wall of the water chamber 402. A first cap 406 is provided at the end of the cleaning pipe 405. By removing the first cap 406 from the end of the cleaning pipe 405, the mud and water stored in the sewage chamber 402 can be discharged from the cleaning pipe 405. A drain pipe 407 is provided on the side wall of the clean water chamber 403. A second cap 408 is provided at the end of the drain pipe 407. By removing the second cap 408 from the end of the drain pipe 407, the clean water in the clean water chamber 403 can be discharged and replaced.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The enclosure assembly is movably mounted in the middle of the traveling vehicle. The enclosure assembly includes a screw cylinder 301, which is located at the top center of the base plate 101. The inner cavity of the screw cylinder 301 penetrates the base plate 101. The outer peripheral wall of the screw cylinder 301 is threaded, while the inner peripheral wall is smooth. A retaining cylinder 303 is fitted into the inner cavity of the screw cylinder 301. Two opposing limiting grooves 302 are provided on the screw cylinder 301, and two opposing limiting blocks 304 are provided on the outer peripheral wall of the retaining cylinder 303. A threaded ring 305 is threaded onto the peripheral wall. An annular groove 306 is provided on the inner peripheral wall of the bottom of the threaded ring 305. A limiting block 304 is engaged in the limiting groove 302 and the annular groove 306. By rotating the threaded ring 305, it can rotate and move up and down on the outer peripheral wall of the screw cylinder 301. Due to the cooperation of the limiting block 304, the limiting groove 302 and the annular groove 306, the threaded ring 305 can drive the surrounding cylinder 303 to move up and down during the rotation and up and down movement on the outer peripheral wall of the screw cylinder 301.

[0043] A storage sleeve 312 is provided at the bottom center of the base plate 101, and a rubber ring 307 is provided at the bottom of the surrounding cylinder 303. When the device is not in use, the rubber ring 307 is stored in the storage sleeve 312. An annular cavity 308 is provided inside the rubber ring 307. An upper abutment plate 309 is provided on the top wall of the annular cavity 308, and a lower abutment plate 310 is provided on the bottom wall of the annular cavity 308. A spring 311 is provided between the upper abutment plate 309 and the lower abutment plate 310. The combination of the annular cavity 308, the upper abutment plate 309, the lower abutment plate 310 and the spring 311 allows the rubber ring 307 to achieve axial elastic deformation.

[0044] Once the device is moved to the corresponding position on the road and stabilized, the screw ring 305 is rotated to rotate and move downward on the outer peripheral wall of the screw cylinder 301, thereby causing the shroud 303 to move downward, causing the rubber ring 307 to follow and move downward, so that the bottom of the rubber ring 307 abuts against the road surface. As the rubber ring 307 continues to move downward, the spring 311 can contract, thus causing the rubber ring 307 to achieve axial elastic deformation and contraction, thereby allowing the bottom of the rubber ring 307 to maintain a certain pressure to abut and seal against the road surface.

[0045] See Figures 1 to 3 The lifting frame is located at the top center of the traveling vehicle, and the enclosure assembly is located below the lifting frame. The lifting frame includes a bracket 601, a screw 602 is vertically mounted on the bracket 601, a motor 603 is mounted on the top of the bracket 601, the drive shaft of the motor 603 is connected to the top of the screw 602, an assembly plate 604 is mounted on both the bracket 601 and the screw 602, the assembly plate 604 is threadedly connected to the screw 602, and a mounting seat 605 and a mounting seat 606 are mounted on the assembly plate 604. By starting the motor 603, the screw 602 can be driven to rotate, and during the rotation of the screw 602, the assembly plate 604 can move up and down.

[0046] See Figures 1 to 7The system includes a core drilling assembly and a water pumping assembly, both mounted on a lifting frame. The outlet of the water pumping assembly is connected to the inner cavity of the core drilling assembly, and the inlet of the water pumping assembly is connected to the water cavity of the storage unit. The drilling section of the core drilling assembly can penetrate the enclosure assembly and extend to the underside of the traveling vehicle to drill into the road. The core drilling assembly includes a second motor 701 and a hollow rotating rod 702. The second motor 701 is mounted on a mounting base 605, and the hollow rotating rod 702 is rotatably locked within an assembly plate 604. A pulley 703 is mounted on the drive shaft of the second motor 701, and a second pulley 704 is mounted on the top of the hollow rotating rod 702. The first pulley 703 is connected to the second pulley 704 via a transmission belt 705, and a core-taking drum 706 is mounted on the bottom of the hollow rotating rod 702. By starting the second motor 701, the core drilling process is completed through the pulleys 703 and 704. After the cooperation of 704 and the transmission belt 705, the hollow rotating rod 702 can be rotated, thereby driving the core-collecting rotating drum 706 to rotate. The water pumping assembly includes a second water pump 901, which is mounted on the second mounting base 606. The suction pipe 903 of the second water pump 901 is equipped with a suction pipe 904. The opening of the suction pipe 904 is placed in the clear water chamber 403 through the water inlet pipe 404. The outlet pipe 902 of the second water pump 901 is placed in the top opening of the hollow rotating rod 702. By starting the second water pump 901, the clear water in the clear water chamber 403 can be pumped into the second water pump 901 through the suction pipe 904 and the suction pipe 903, and then sprayed out from the outlet pipe 902 into the hollow rotating rod 702, causing the clear water to flow down through the inner cavity of the hollow rotating rod 702 into the inner cavity of the core-collecting rotating drum 706.

[0047] After the bottom of the rubber ring 307 is pressed against and sealed against the road surface, the motor 701 is started, and after the cooperation of pulley 703, pulley 704 and transmission belt 705, the hollow rotating rod 702 is rotated, which in turn drives the core-taking drum 706 to rotate. Then the water pump 901 is started, and the clean water in the clean water chamber 403 is pumped into the water pump 901 through the suction pipe 904 and suction pipe 903. Then the clean water is sprayed out from the water outlet pipe 902 into the hollow rotating rod 702, so that the clean water flows down into the inner cavity of the hollow rotating rod 702 and into the inner cavity of the core-taking drum 706. Then the motor 603 is started to drive the screw 602 to rotate. During the rotation of the screw 602, the assembly plate 604 and the components set on it move down, so that the core-taking drum 706 rotates and moves down through the coaxial tube 303 and drills into the road to realize the drilling and core-taking operation.

[0048] During the process of the coring drum 706 drilling into the road, the clean water in the clean water chamber 403 is pumped into the water pump 901 through the suction pipe 904 and the suction pipe 903, and then sprayed out from the water outlet pipe 902 into the hollow rotating rod 702, so that the clean water flows down into the inner cavity of the hollow rotating rod 702 and into the inner cavity of the coring drum 706 to cool and lubricate the coring drum 706.

[0049] The sludge suction assembly is located on the back of the vehicle. The suction inlet of the sludge suction assembly is connected to the inner cavity of the enclosure assembly, and the discharge outlet of the sludge suction assembly is connected to the sludge chamber of the storage unit. The sludge suction assembly includes a water pump 501, which is mounted on the placement frame 104. A suction pipe 503 is provided on the suction pipe 502 in the water pump 501. One end of the suction pipe 503 passes through the bottom peripheral side wall of the enclosure 303 and extends into the inner cavity of the enclosure 303. A sewage discharge pipe 505 is provided on the discharge pipe 504 in the water pump 501, and the opening of the sewage discharge pipe 505 faces the sewage chamber 402.

[0050] During the process of drilling and coring the core inside the road using the core drilling drum 706, the generated mud and water are contained within the confining cylinder 303. At this time, by starting the water pump 501, the mud and water contained within the confining cylinder 303 are pumped into the water pump 501 through the suction pipe 503 and the pumping pipe 502. Then, it is discharged into the sewage chamber 402 through the discharge pipe 504 and the sewage pipe 505 for temporary storage, thereby preventing the generated mud and water from flowing out onto the road.

[0051] See Figure 1 , Figure 5 and Figure 8 The top edge of the core-taking drum 706 is provided with an installation groove 801. A clamping plate 802 is installed in the installation groove 801. A fixing cylinder 803 is provided in the side wall of the installation groove 801 near the center of the core-taking drum 706. A stop spring 804 and a stop post 805 are provided in the fixing cylinder 803. The stop spring 804 is located between the inner bottom of the fixing cylinder 803 and the stop post 805. A screw 806 is screwed into the outer peripheral wall of the core-taking drum 706 located in the installation groove 801. The clamping plate 802 is located between the stop post 805 and the screw 806.

[0052] After the core-retrieving drum 706 is drilled into position, the screw ring 305 is rotated to move it upwards on the outer circumferential wall of the screw cylinder 301, thereby moving the surrounding cylinder 303 upwards. This causes the rubber ring 307 to move upwards and be housed in the receiving sleeve 312, exposing the top of the core-retrieving drum 706. Then, by rotating the screw 806, the screw-in end of the screw 806 abuts against the clamping plate 802, causing the abutment spring 804 to contract. This causes the clamping plate 802 to move closer to the center of the core-retrieving drum 706, thus achieving the desired rotation. The core sample is clamped by the peripheral wall inside the core-taking drum 706. Then, the motor 603 is started to drive the screw 602 to rotate, causing the assembly plate 604 and the components on it to move upward, thereby lifting the core-taking drum 706 out of the road. Finally, the screw 806 is rotated to release the screw from the clamping plate 802, that is, to release the clamping operation of the clamping plate 802 on the core sample inside the core-taking drum 706. At this time, the core sample can slide out and fall out of the core-taking drum 706, and the sampling is finally completed.
