Description

Technical Field

[0001] The present invention relates to a rapid in-situ parameter tester, in particular to an intelligent adaptive rapid in-situ parameter tester for geotechnical engineering, belonging to the technical field of geotechnical engineering. Background Art

[0002] The rapid in-situ parameter tester is the core equipment for achieving efficient and accurate exploration in the field of geotechnical engineering. In the prior art, a heavy dynamic penetration in-situ tester is disclosed in the patent with the application number 202320462098.7. In order to reduce the work burden of the testers, the output shaft of the motor drives the half gear and the rack plate to start running, and then the rack plate drives the sliding cylinder and the drop hammer to rise. After the half gear disengages from the rack plate, under the action of gravity, the drop hammer falls to the upper end of the hammer seat, thereby driving the sounding rod and the probe to move downward. In this way, the drop hammer repeatedly exerts an impact force on the hammer seat.

[0003] The similar applications currently still have deficiencies as follows: Since the measurement position of the device is not fixed and the ground on the construction site is uneven, the device cannot perform self-balancing adjustment during use, and it takes a long time for adjustment preparation, which affects the measurement rate. In addition, during use, the data cannot be automatically recorded. Moreover, during the testing process, the insertion length of the probe is not constant, and tooth hooking is likely to occur between the gear and the incomplete gear, which affects the use stability of the device.

[0004] Therefore, an intelligent adaptive rapid in-situ parameter tester for geotechnical engineering is designed to optimize the above problems. Summary of the Invention

[0019] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0020] like Figures 1-7As shown in the figure, this embodiment provides a rapid tester for intelligent adaptive in-situ parameters of geotechnical engineering, including a base 1. The base 1 is circular in shape. A ball groove 2 is provided at the middle position of the base 1. A sphere 3 is rotatably installed inside the ball groove 2. A sleeve 4 is vertically fixed to the bottom of the sphere 3. A cone block 5 is fixed to the bottom end of the sleeve 4. The top of the sphere 3 protrudes above the top of the base 1. A lower mounting plate 6 is horizontally fixed to the top end of the sphere 3. Through grooves 7 are provided on the sphere 3, the lower mounting plate 6 and the cone block 5. The through grooves 7 are on the same axis as the sleeve 4, and the inner diameter of the through grooves 7 is the same as that of the sleeve 4. A sounding rod 8 is vertically slidably arranged inside the through grooves 7. The inner diameter of the through grooves 7 is φ30mm, and the outer diameter of the sounding rod 8 is φ29.8mm to ensure that the verticality deviation of the sounding rod is ≤0.5°. A probe 9 is fixed to the bottom end of the sounding rod 8. An M20 external thread is provided at the bottom end of the sounding rod 8, and a corresponding internal thread is provided at the top of the probe 9. A hammer base 10 is installed at the top end of the hammer base 10. A locking mechanism 11 for fixing the sphere 3 is provided on the top of the base 1. Legs 12 are evenly hingedly installed on the outer side of the bottom of the base 1. The legs 12 are hinged to the base 1 through a stainless steel pin with a diameter of 8mm. Damping washers are provided at both ends of the pin, and the sway amplitude after the legs 12 are unfolded is ≤5°. A positioning mechanism 13 is provided between each leg 12 and the inner bottom of the base 1. An impact mechanism 16 is provided on the top of the lower mounting plate 6. An installation frame 17 is provided on one side of the top of the base 1. A storage box 18 is provided at the bottom of the installation frame 17. A display screen 20 is provided at the middle position of the top of the installation frame 17. A controller 19 is provided at one end of the top of the installation frame 17. A first laser displacement sensor 14 electrically connected to the controller 19 is provided on the top of the lower mounting plate 6 and directly below the hammer base 10. A counting sensor 15 electrically connected to the controller 19 is provided at the middle position of the hammer base 10. The controller 19 is electrically connected to the display screen 20 through a wire.

[0021] General working principle: The device is powered by a detachable lithium battery pack. During use, first extend the outriggers 12 outwards, and then place the outriggers 12 at the area to be tested. Since the ground is not a horizontal plane, the top of the base 1 has a certain inclination angle. However, since the sphere 3 can rotate inside the spherical groove 2, and the bottom of the sphere 3 has a counterweight composed of a sleeve 4 and a cone block 5, under the action of gravity, the position of the sphere 3 is adjusted, and the sleeve 4 and the cone block 5 are perpendicular to the horizontal plane. Then, use the locking mechanism 11 to fix the position of the sphere 3. Then, vertically insert the sounding rod 8 into the through groove 7 at the top of the sphere 3, and after passing through the bottom of the cone block 5, install a probe 9 at the bottom end of the sounding rod 8. The sounding rod 8 is perpendicular to the horizontal plane. Then, use the impact mechanism 16 to apply pressure to the hammer seat 10, and the probe 9 enters the soil. Use the first laser displacement sensor 14 to measure the distance that the hammer seat 10 moves downwards. The initial position of the sounding rod 8 is the 0 point, and the first 30 cm penetration depth is used as the "pre-drilling" section. When the penetration depth of the probe 9 ≥ 30 cm, the first laser displacement sensor 14 triggers the "formal test" mode, and the counting sensor 15 is cleared. Starting from the position after the end of the pre-drilling section, the first laser displacement sensor 14 measures the data again, and uses the counting sensor 15 to record the number of times the impact hammer seat 10 strikes. The number of hammer blows is recorded every 10 cm of penetration, and the measured distance value and the number of times are transmitted to the inside of the controller 19. When the 10 cm set threshold is reached, the controller 19 locks the current number of impacts, uses the display screen 20 to display the data of this time, and resets the measurement results of the first laser displacement sensor 14 and the counting sensor 15. Conduct repeated tests again, continue to hammer until the predetermined test depth is reached, and obtain multiple test data.

[0022] In this embodiment, the locking mechanism 11 includes an annular groove 1101, an adjusting ring 1102, a strip-shaped groove 1103, a pressing rod 1104, and a flat thread 1105. The annular groove 1101 is opened on the outer side of the top of the base 1. The adjusting ring 1102 is slidably arranged inside the annular groove 1101. The top of the annular groove 1101 is evenly provided with strip-shaped grooves 1103 in an annular array, and the strip-shaped grooves 1103 are perpendicular to the section plane of the base 1. The ends of the strip-shaped grooves 1103 communicate with the inside of the ball groove 2. Pressing rods 1104 are slidably arranged inside the strip-shaped grooves 1103. Flat threads 1105 are opened at the bottom of the adjusting ring 1102 and the top of the pressing rod 1104. The adjusting ring 1102 and the pressing rod 1104 are meshed through the flat thread 1105. The flat thread 1105 adopts a trapezoidal thread with a pitch of 2 mm and a thread profile angle of 30°. 10 turns of threads are arranged at the bottom of the adjusting ring 1102, and meshing threads are correspondingly arranged at the top of the pressing rod 1104 to ensure that when the adjusting ring 1102 rotates one week, the pressing rod 1104 axially displaces 2 mm. The end of the pressing rod 1104 close to the sphere 3 is embedded with an elastic rubber pad (Shore hardness 60A), and an elastic deformation of 1-3 mm is generated after contacting the sphere.

[0023] Local working principle: After the position of the sphere 3 is adjusted, rotate the adjusting ring 1102. Since the flat thread 1105 at the bottom of the adjusting ring 1102 is meshed with the pressing rod 1104 and the strip-shaped groove 1103 guides the pressing rod 1104, during the rotation of the adjusting ring 1102, the movement direction of the pressing rod 1104 towards the sphere 3 can be simultaneously controlled to squeeze and fix the sphere 3.

[0024] In this embodiment, anti-slip patterns are evenly opened on the outer side of the adjusting ring 1102 along the circumferential direction, and one end of the pressing rod 1104 close to the sphere 3 is arc-shaped.

[0025] Local working principle: The opening of the anti-slip patterns can facilitate the manual control of the rotation of the adjusting ring 1102. The arc-shaped setting of the end of the pressing rod 1104 can increase the contact area with the sphere 3 and improve the stability.

[0026] In this embodiment, three groups of legs 12 are provided, and the bottom ends of the legs 12 are all conical.

[0027] Local working principle: When supporting the base 1, the triangular support method is adopted, which is more stable. The conical setting of the bottom ends of the legs 12 can improve the stability of inserting into the soil.

[0028] In this embodiment, the positioning mechanism 13 includes a sliding groove 1301, a sliding block 1302, a support rod 1303 and a limiting component. The sliding groove 1301 is opened on the lower surface of the base 1. Sliding blocks 1302 are all slidably arranged inside the sliding groove 1301. Support rods 1303 are all hingedly installed between the inner sides of the sliding blocks 1302 and the legs 12. Limiting components are all arranged on the sliding blocks 1302.

[0029] Local working principle: In the initial state, the bottoms of multiple legs 12 gather together, making the device smaller in volume, convenient to carry and store. When in use, pull the legs 12 outwards. The sliding blocks 1302 move from the inner end to the outer end of the sliding groove 1301, and then use the limiting component to limit the position of the sliding blocks 1302 to stabilize the position of the legs 12.

[0030] In this embodiment, the limiting component includes a slot 1304, an installation groove 1305, a plug 1306, a spring 1307 and a pull rope 1308. The slots 1304 are opened at both ends of the top of the sliding groove 1301. The installation groove 1305 is opened on the top of the sliding block 1302. A plug 1306 is slidably arranged inside the installation groove 1305. A spring 1307 is arranged between the end of the plug 1306 and the end of the installation groove 1305. A pull rope 1308 is fixed to the bottom end of the plug 1306, and the bottom end of the pull rope 1308 slidably extends to the bottom of the sliding block 1302. The length of the sliding groove 1301 is 150 mm, the diameter of the slots 1304 at both ends is 8 mm. The spring 1307 is made of stainless steel compression spring, with an elastic coefficient k = 5 N / mm, a free length of 20 mm, and pre-compressed by 5 mm and installed in the installation groove 1305 to ensure that the locking force when the plug 1306 is inserted into the slot 1304 is ≥ 10 N, and the pull rope 1308 can overcome the spring force to unlock when the pulling force is ≥ 15 N.

[0031] Local working principle: Before expanding the position of the legs 12, first pull the plug 1306 downward through the pull rope 1308. The plug 1306 enters from the inside of the slot 1304 into the installation groove 1305 to release the limit on the legs 12. Then pull the legs 12 outwards. After the legs 12 are pulled out, release the pull rope 1308. Under the elastic force of the spring 1307, the plug 1306 is inserted into the slot 1304 again to lock the position of the legs 12.

[0032] In this embodiment, an arc chamfer is provided at the top end of the plug 1306, and a pull ring is fixed to the bottom end of the pull rope 1308.

[0033] Local working principle: The arc chamfer at the top end of the plug 1306 can facilitate insertion into the slot 1304, and the setting of the pull ring can facilitate the control of the pull rope 1308.

[0034] In this embodiment, the impact mechanism 16 includes a sliding rod 1602, an upper mounting plate 1603, an electric telescopic rod 1604, a permanent magnet 1605, a limit block 1606, a through-hammer 1607, an L-shaped rod 1608, and a second laser displacement sensor 1609. The sliding rods 1602 are uniformly and vertically arranged at the top of the lower mounting plate 6. An upper mounting plate 1603 is horizontally fixed between the tops of the sliding rods 1602. An electric telescopic rod 1604 is vertically mounted on the top of the upper mounting plate 1603. The output end of the electric telescopic rod 1604 extends to the bottom of the upper mounting plate 1603. A permanent magnet 1605 is mounted at the output end of the electric telescopic rod 1604. Limit blocks 1606 are slidably arranged on the sliding rods 1602. A through-hammer 1607 is fixed between the limit blocks 1606. The mass of the through-hammer 1607 is 10 kg, the total mass of the probe 9 and the sounding rod 8 is 5 kg, and the total gravity G = 150 N. The suction force F of the permanent magnet 1605 = 120 N (greater than the gravity of the through-hammer 100 N and less than the total gravity 150 N). A neodymium iron boron permanent magnet is used, and the surface magnetic induction intensity ≥ 0.5 T, and the adsorption distance from the through-hammer 1607 ≤ 5 mm. The bottom end of a set of limit blocks 1606 is fixed with an L-shaped rod 1608. The length of the L-shaped rod 1608 is 50 cm. The bottom end of the L-shaped rod 1608 extends directly below the hammer base 10. The second laser displacement sensor 1609 is electrically connected to the controller 19 through a wire. The output end of the controller 19 is electrically connected to the electric telescopic rod 1604 through a wire. The second laser displacement sensor 1609 measures the distance between the permanent magnet 1605 and the through-hammer 1607 in real time. When the distance > 10 mm, the controller 19 drives the electric telescopic rod 1604 to descend at a speed of 50 mm / s until the distance ≤ 5 mm and re-adsorbs, avoiding dry hitting or excessive impact.

[0035] Local working principle: When impacting the hammer base 10, the permanent magnet 1605 magnetically attracts the through-hammer 1607. The electric telescopic rod 1604 is used to control the upward movement of the through-hammer 1607. At the same time, the L-shaped rod 1608 also moves accordingly. After the bottom end of the L-shaped rod 1608 contacts the bottom of the hammer base 10, since the suction force of the permanent magnet 1605 on the through-hammer 1607 is less than the sum of the weights of the through-hammer 1607 and the probe 9, the L-shaped rod 1608 will prevent the continuous upward movement of the through-hammer 1607 until it separates from the permanent magnet 1605. The through-hammer 1607 freely falls under the action of gravity and impacts the hammer base 10. After the through-hammer 1607 contacts the hammer base 10, the second laser displacement sensor 1609 measures the positions of the through-hammer 1607 and the upper mounting plate 1603, and then controls the telescopic amount of the electric telescopic rod 1604 to ensure that the permanent magnet 1605 can magnetically attract and position the through-hammer 1607. Repeat the above steps to continuously impact the hammer base 10.

[0036] In this embodiment, socket sleeves 1601 are uniformly fixed to the top of the lower mounting plate 6, and the bottom ends of the sliding rods 1602 are inserted into the interior of the socket sleeves 1601. The socket sleeves 1601 are distributed in a triangular pattern.

[0037] Local working principle: The sliding rods 1602 are inserted into the socket sleeves 1601, enabling the device to be disassembled after use, facilitating the transfer of the device.

[0038] In this embodiment, sliding holes are formed in the limiting blocks 1606, and balls are rotatably mounted on the inner walls of the sliding holes.

[0039] Local working principle: The setting of the balls can reduce the resistance of the limiting blocks 1606 during downward movement, thereby reducing the error of the impact force.

[0040] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
