Description

Technical Field

[0001] This invention relates to the field of construction coring technology, specifically to an automated construction coring device. Background Technology

[0002] When core samples are needed for compressive and flexural tests on cement concrete, asphalt concrete, and limestone foundations such as highways, airports, ports, docks, and dams, a concrete core sampling machine is generally used. Chinese Patent Application No. 202210878939.2 discloses "A concrete core sampling machine, relating to concrete engineering testing instruments, which improves the problem of poor stability during the movement of the concrete core sampling machine. It includes a base and a core sampling machine body. A mounting seat is provided on the base, and the core sampling machine body is mounted on the mounting seat. Several [unclear - possibly referring to a specific type of equipment] are provided on the base." The upper base column has a mounting base that slides vertically along it. A lifting mechanism is installed on the upper base column. A lower base column, corresponding to the upper base column, is mounted on the base. A buffer spring connects the upper and lower base columns. Several rotating plates are rotatably connected to the lower base columns, each with a locking block. The upper base column has locking grooves and a fixing component. The rotating plates have fixed and idle states. A control component is installed on the lower base column, and an unlocking component is installed on the upper base column. This application improves the stability of the concrete core sampling machine during movement.

[0003] This technical solution only addresses the issue of poor stability during the movement of concrete core sampling machines. Currently, ordinary water drills are typically used for highway core sampling, propelled by a manually pushed trolley. This results in extremely slow progress, especially over long distances. Upon reaching the core sampling location, manual pressure on the concrete core sampling machine is difficult to control, leading to frequent worker fatigue and very low efficiency. Furthermore, the unstable water flow during drilling with existing concrete core sampling machines causes excessively high drill bit temperatures and rapid wear. Additionally, workers must operate alongside the machine, resulting in significant noise and high generator temperatures, creating a poor working environment and further reducing efficiency.

Both the first slide rod 316 and the second slide rod 317 are slidably installed inside the slide 314. When the pedal 315 is pulled out of the storage box 313, the second slide rod 317 slides down to the right corner of the slide 314. At this time, the first slide rod 316 cannot slide, thus fixing the pedal 315. The pedal 315 provides a foothold for the operator when driving.

The electric drive device 302 is electrically connected to the generator 2 via a wire, and the water pump 402 is electrically connected to the generator 2 via a wire. By starting the water pump 402, water in the stainless steel water tank 401 is drawn into the water pump 402 through the suction pipe 403 and then flows out through the outlet pipe 404.

[0037] The automatic core-retrieving mechanism 5 includes a lifting motor 502, a support block 503, a horizontal drive shaft 504, and a support frame 505. The lifting motor 502 is bolted to the top center of the chassis 1 and is electrically connected to the generator 2 via a wire. The support block 503 is bolted to the top center of the chassis 1, slightly rearward. The horizontal drive shaft 504 is inserted and movably mounted on the top of the support block 503. The end of the horizontal drive shaft 504 near the lifting motor 502 is bolted to the output shaft of the lifting motor 502. The bottom end of the support frame 505 is bolted to the bottom center of the chassis 1, slightly rearward. The lifting motor 502 drives the horizontal drive shaft 504 to rotate, and the support block 503 supports the horizontal drive shaft 504.

[0038] The automatic core-retrieving mechanism 5 includes a first bevel gear 506, a second bevel gear 507, a vertical drive shaft 508, and a first pulley 509. The first bevel gear 506 is fixedly mounted on the end of the horizontal drive shaft 504 away from the lifting motor 502 by bolts. The second bevel gear 507 is located below the first bevel gear 506 and meshes with it. The bottom end of the vertical drive shaft 508 is movably mounted on the bottom end of the support frame 505 via a bearing. The first pulley 509 is fixedly mounted on the top center of the vertical drive shaft 508 by bolts. Through the meshing connection between the first bevel gear 506 and the second bevel gear 507, when the first bevel gear 506 rotates, it drives the second bevel gear 507 to rotate, causing the vertical drive shaft 508 to rotate with the second bevel gear 507, and causing the first pulley 509 to rotate with the vertical drive shaft 508.

[0039] The automatic core-picking mechanism 5 includes a drive belt 510, a lifting threaded rod 511, a second pulley 512, a limit rod 513, and a lifting slider 514. The end of the drive belt 510 closest to the lifting motor 502 is movably sleeved on the first pulley 509. The bottom end of the lifting threaded rod 511 is movably mounted on the top center of the mounting bracket 501 via a bearing. The top end of the lifting threaded rod 511 is movably mounted on the top center of the support bracket 505 away from the lifting motor 502 via an insertion mechanism. The second pulley 512 is fixedly mounted on the top center of the lifting threaded rod 511 with bolts. The drive belt 510 is located away from the lifting motor 502. One end of the 2 is movably sleeved on the second pulley 512. The bottom end of the limiting rod 513 is fixedly installed by bolts. The cross-section of the limiting rod 513 is rectangular. The end of the lifting slider 514 near the lifting motor 502 is movably sleeved on the lifting threaded rod 511 by threads. The end of the lifting slider 514 away from the lifting motor 502 is movably sleeved on the limiting rod 513. The second pulley 512 is driven to rotate by the transmission belt 510. At this time, the lifting threaded rod 511 rotates with the second pulley 512. Due to the limiting of the limiting rod 513, when the lifting threaded rod 511 rotates, it drives the lifting slider 514 to move downward.

[0040] The automatic core-retrieving mechanism 5 includes a connecting plate 515, a core-retrieving motor 516, a connecting shaft 517, and a core-retrieving cylinder 518. The lifting slider 514, near the lifting motor 502, is threadedly connected to the lifting threaded rod 511. The lifting slider 514, away from the lifting motor 502, is movably connected to the limiting rod 513. The connecting plate 515 is bolted to the side of the lifting slider 514 away from the chassis 1. The core-retrieving motor 516 is bolted to the top center of the end of the connecting plate 515 away from the chassis 1. The core-retrieving motor 516 is electrically connected to the generator 2 via a wire. The top of the connecting shaft 517 is bolted to the output shaft of the core-retrieving motor 516. The core-retrieving cylinder 518... The top center of the core retrieval cylinder 518 is fixedly welded to the bottom of the connecting shaft 517. Several serrations are fixedly welded to the bottom of the core retrieval cylinder 518. An installation rod is fixedly bolted to the right side of the top of the chassis 1, which is located in front of the power generation device 2. A control box 6 is fixedly bolted to the top of the installation rod. The control box 6 controls the start of the core retrieval motor 516, which drives the connecting shaft 517 to rotate, causing the core retrieval cylinder 518 to rotate at high speed. The high-speed rotation of the core retrieval cylinder 518 causes it to enter the ground. The control box 6 controls the insertion depth of the core retrieval cylinder 518. Then, the control box 6 controls the lifting motor 502 to reverse, causing the core retrieval cylinder 518 to rise, thereby performing the core retrieval operation.

[0041] Working principle: When in use, the power generation device 2 is activated to provide power to the inverted electric vehicle 3, the flow mechanism 4, and the automatic core sampling mechanism 5. Then, the electric drive device 302 is activated to drive the drive shaft 303 to rotate. The drive shaft 303 drives the drive wheel 304 to rotate, so that the inverted electric vehicle 3 starts to move. The chassis 1 is supported by the drive wheel 304 and the follower wheel 306. The direction is controlled by the handle 309. The LED headlight 310 provides illumination for nighttime construction. The rotatable seat 312 facilitates driving. The pedal 315 is then pulled out from the storage box 313. When the second slide bar 317 slides in the slide groove 314 to the right corner of the slide groove 314, it slides downward. At this time, the first slide bar 316 cannot slide, so the pedal 315 is fixed. The pedal 315 provides a foothold for the construction personnel when driving. The inverted electric vehicle 3 carries the core sampling equipment forward on the construction road, which can carry out long-distance construction and has a fast forward speed, thus improving work efficiency.

[0042] When the electric donkey scooter 3 moves to the core extraction position, the water pump 402 is started via the control box 6. Water from the stainless steel water tank 401 is drawn into the water pump 402 through the suction pipe 403 and then flows out through the outlet pipe 404, directing the water to the core extraction location. The control box 6 controls the water pump 402 to ensure stable control of the flow rate and pressure of the water flowing out of the outlet pipe 404. The control box 6 also controls the lifting motor 502, which drives the horizontal transmission shaft 504 to rotate. This causes the first bevel gear 506 to rotate along with the horizontal transmission shaft 504. Since the first bevel gear 506 is meshed with the second bevel gear 507, when the first bevel gear 506 rotates, it drives the second bevel gear 507 to rotate, causing the vertical transmission shaft 508 to rotate along with the second bevel gear 507. This causes the first pulley 509 to rotate along with the vertical transmission shaft 508. When the first pulley 509 rotates, it drives the second pulley 508 through the transmission belt 510. When pulley 512 rotates, the lifting threaded rod 511 rotates along with the second pulley 512. Due to the limiting rod 513, when the lifting threaded rod 511 rotates, it drives the lifting slider 514 to move downward. At this time, the connecting plate 515 moves downward along with the lifting slider 514, and the core-taking cylinder 518 moves downward along with the connecting plate 515. The core-taking motor 516 is started by the control box 6, which drives the connecting shaft 517 to rotate, causing the core-taking cylinder 518 to rotate at high speed. The core-taking cylinder 518 rotates into the ground at high speed. The insertion depth of the core-taking cylinder 518 is controlled by the control box 6. Then, the lifting motor 502 is reversed by the control box 6, causing the core-taking cylinder 518 to rise, thus performing the core-taking operation. During the core-taking process, the water flowing out by the water flow mechanism 4 cools the core-taking cylinder 518 to prevent the temperature from getting too high when the core-taking cylinder 518 rotates at high speed, which would cause the cutter head to wear too quickly.
