Abstract
Description
Technical Field
[0001] This utility model relates to the field of static cone penetrometer technology, and in particular to a static cone penetrometer with an anti-deviation structure. Background Technology
[0002] A static cone penetrometer (PCP) is an in-situ testing instrument that assesses the physical and mechanical properties of soil by measuring the penetration resistance of soil layers. It is primarily used in civil engineering and municipal engineering. PCPs are suitable for in-situ testing of foundation soils in general cohesive soils, soft soils, loess, and dense sandy soils, including civil engineering, municipal works, highways, and engineering foundations. PCPs are commonly used exploration equipment. Their main uses include: determining vertical and horizontal variations in soil strata; performing mechanical stratification; determining the bearing capacity of natural foundations and estimating the bearing capacity of single piles; assessing the likelihood of soil liquefaction; determining the undrained shear strength of soft soils; and providing calculation indicators for the bearing capacity of soft soil foundations and slope stability.
[0003] However, existing static cone penetrometers have certain shortcomings:
[0004] First, the existing static cone penetrometer does not have anti-deviation components. If the soil of the test site is relatively soft, the static cone penetrometer will not be able to provide good stable support when placed horizontally due to its small bottom area. The device is prone to tilting and unevenness, which will affect the test.
[0005] Secondly, existing static penetrometers typically control the raising and lowering of the probe using a hand crank. During the testing process, the hand crank cannot keep the probe moving at a constant speed, which can easily affect the accuracy of the test. Furthermore, since there is no restriction on the probe during the raising and lowering process, the probe is prone to shaking, which can affect the testing work. Utility Model Content

[0010] Preferably, the inner walls on both sides of the mounting bracket are provided with limiting grooves, the limiting grooves are adapted to the mounting plate, and the outer walls on both sides of the mounting plate are welded with limiting blocks that are slidably connected to the limiting grooves.
[0011] Preferably, threaded rods are rotatably mounted on one end of the bottom inner wall of the mounting bracket and one end of the top outer wall of the base plate.

The output shaft of the servo motor is adapted to the threaded rod. The servo motor is provided with a protective cover adapted to it. Heat dissipation holes are opened on both sides of the outer wall of the protective cover.
[0012] Preferably, the anti-deviation plate is inserted into the base, and the outer wall of the anti-deviation plate near the base is provided with equally spaced fixing pins. The outer wall of the base near the anti-deviation plate is provided with equally spaced fixing holes, the fixing holes are inserted into the fixing pins, and the inner wall of the fixing holes is provided with a matching anti-slip sleeve, the anti-slip sleeve being made of rubber.
[0013] Preferably, support plates are slidably installed on both ends of the outer walls of adjacent sides of the base. The support plates are adapted to the base and the bottom plate, respectively.

[0014] In summary, the technical effects and advantages of this utility model are as follows:
[0015] 1. In this utility model, when the penetrometer body is working, the anti-deviation plate is connected to the penetrometer body. After the connection is completed, the positioning sleeve set at the bottom of the anti-deviation plate is inserted into the soil to fix the device. After the device is fixed, the rotating disk at the top of the adjusting shaft is rotated. Since the adjusting shaft and the inner wall of the positioning sleeve are connected by a threaded rotation, the rotation of the rotating disk can drive the adjusting shaft and the positioning sleeve to rotate, thereby realizing the raising and lowering of the adjusting shaft. Since the anti-deviation plate is located on both sides of the penetrometer body, and anti-deviation components are set at both ends of the anti-deviation plate, the four sets of anti-deviation components are adjusted to each other. The device can be leveled. The cross level on the top of the anti-deviation plate makes it easy to observe whether the penetrometer body is in a horizontal state. Compared with traditional penetrometers, the anti-deviation structure corrects the penetrometer body, ensuring that the penetrometer body is in a horizontal state during operation, making the detection results more accurate. At the same time, the device is fixed by the positioning sleeve. When the height of the anti-deviation plate is adjusted by the adjusting shaft, the positioning sleeve will not rotate and affect the stability of the device. The protective plate on the outer wall of the positioning sleeve protects the positioning sleeve and prevents the entire positioning sleeve from sinking into the soil and affecting the adjustment of the anti-deviation plate.
[0016] 2. In this utility model, during the operation of the probe body, the probe is connected to the mounting cylinder. Then, the servo motor drives the threaded rod to rotate, which drives the mounting plate to descend and make the probe contact the soil for detection. Compared with the traditional hand-cranked method to control the probe's lifting and lowering, the probe can maintain a uniform speed and is more stable when applying pressure to the soil, which is conducive to improving the detection accuracy. When the mounting plate moves up and down, the limiting groove restricts the mounting plate to ensure the stability of the mounting plate's up and down movement, so that it will not shake during the up and down movement and avoid affecting the operation of the probe.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Reference Figure 1-4The static penetrometer shown includes a penetrometer body 1, which is equipped with an anti-deviation structure adapted to the penetrometer body 1. The anti-deviation structure includes an anti-deviation plate 2, and anti-deviation components are provided at both ends of the top outer wall of the anti-deviation plate 2. The anti-deviation components include rotating holes at both ends of the top outer wall of the anti-deviation plate 2. An adjusting shaft 4 is rotatably installed on the inner wall of the rotating hole. A positioning sleeve 3 is threadedly connected to the outer wall of the adjusting shaft 4. The inner wall of the positioning sleeve 3 is provided with equally spaced internal threads. The outer wall of the adjusting shaft 4 is provided with external threads adapted to the internal threads. A protective disc 6 is provided on the outer wall of the positioning sleeve 3. The diameter of the protective disc 6 is larger than the diameter of the positioning sleeve 3. A rotating disc 5 adapted to the adjusting shaft 4 is provided on the top of the adjusting shaft 4. A cross level 7 adapted to the anti-deviation plate 2 is provided at the middle position of the top outer wall of the anti-deviation plate 2.
[0025] With the above structure: When the penetrometer body 1 is working, the anti-deviation plate 2 is connected to the penetrometer body 1. After the connection is completed, the positioning sleeve 3 set at the bottom of the anti-deviation plate 2 is inserted into the soil to fix the device. After the device is fixed, the rotating disk 5 at the top of the adjusting shaft 4 is rotated. Since the adjusting shaft 4 and the inner wall of the positioning sleeve 3 are connected by a threaded rotation, the rotation of the rotating disk 5 can drive the adjusting shaft 4 and the positioning sleeve 3 to rotate, thereby realizing the raising and lowering of the adjusting shaft 4. Since the anti-deviation plate 2 is located on both sides of the penetrometer body 1, and anti-deviation components are set at both ends of the anti-deviation plate 2, the four sets of anti-deviation components are adjusted to each other. The device can be leveled. The cross level 7 on the top of the anti-deviation plate 2 makes it easy to observe whether the penetrometer body 1 is in a horizontal state. Compared with traditional penetrometers, the anti-deviation structure corrects the deviation of the penetrometer body 1, ensuring that the penetrometer body 1 is in a horizontal state during operation, making the detection results more accurate. At the same time, the device is fixed by the positioning sleeve 3. When the height of the anti-deviation plate 2 is adjusted by the adjusting shaft 4, the positioning sleeve 3 will not rotate and affect the stability of the device. The protective plate 6 on the outer wall of the positioning sleeve 3 protects the positioning sleeve 3 and prevents the entire positioning sleeve 3 from sinking into the soil and affecting the adjustment of the anti-deviation plate 2.
[0026] like Figure 1As shown, the probe body 1 includes a base 9, which is adapted to the anti-deviation plate 2. A base plate 10 is bolted to the top outer wall of the base 9. Mounting brackets 11 are welded to both ends of the top outer wall of the base plate 10. The mounting brackets 11 have a "U" shaped structure. A probe assembly is slidably mounted on the inner wall of the mounting brackets 11. The probe assembly is adapted to the mounting brackets 11. The probe assembly includes a mounting plate 12 slidably mounted on the inner wall of the mounting brackets 11. A mounting hole is opened on the top outer wall of the mounting plate 12. A mounting cylinder 13 is installed on the inner wall of the mounting hole. A probe 14 is rotatably mounted on the inner wall of the mounting cylinder 13 by a thread. The probe 14 is adapted to the mounting cylinder 13 and the base plate 10 respectively. One end of the bottom inner wall of the mounting bracket 11 and the top outer wall of the base plate 10 are rotatably mounted with screws. The threaded rod 15 is connected to the mounting plate 12 by a threaded rotation. A servo motor 16 is bolted to one end of the top outer wall of the mounting frame 11. The output shaft of the servo motor 16 is adapted to the threaded rod 15. The servo motor 16 is equipped with a protective cover adapted to it. Heat dissipation holes are opened on both sides of the outer wall of the protective cover. During the operation of the probe body 1, the probe 14 is connected to the mounting cylinder 13. Then, the servo motor 16 drives the threaded rod 15 to rotate, which drives the mounting plate 12 to descend, so that the probe 14 contacts the soil for detection. Compared with the traditional manual method of controlling the raising and lowering of the probe 14, the probe 14 can maintain a uniform speed movement, and the probe 14 is more stable when applying pressure to the soil, which is conducive to improving the detection accuracy.
[0027] like Figure 4 As shown, the inner walls on both sides of the mounting bracket 11 are provided with limiting grooves 17, which are adapted to the mounting plate 12. The outer walls on both sides of the mounting plate 12 are welded with limiting blocks that are slidably connected to the limiting grooves 17. When the mounting plate 12 moves up and down, the limiting grooves 17 restrict the mounting plate 12 to ensure the stability of the mounting plate 12's up and down movement, so that it will not shake during the up and down movement and avoid affecting the operation of the probe 14.
[0028] like Figure 2 As shown, the anti-deviation plate 2 is inserted into the base 9. The outer wall of the anti-deviation plate 2 near the base 9 is provided with equally spaced fixing pins 18. The outer wall of the base 9 near the anti-deviation plate 2 is provided with equally spaced fixing holes 19. The fixing holes 19 are inserted into the fixing pins 18. The inner wall of the fixing holes 19 is provided with a matching anti-slip sleeve 20. The anti-slip sleeve 20 is made of rubber. The connection between the fixing pins 18 and the fixing holes 19 facilitates the connection between the anti-deviation plate 2 and the base 9. When the probe body 1 is working, the anti-deviation structure is connected to it by insertion, which facilitates the carrying of the probe body 1 and the anti-deviation component and makes it more convenient to use.
[0029] like Figure 2As shown, support plates 8 are slidably installed on both ends of the outer walls of adjacent sides of the base 9. The support plates 8 are adapted to the base 9 and the base plate 10 respectively. Friction pads 23 are provided on the bottom outer wall of the support plate 8 and the bottom outer wall of the anti-deviation plate 2 respectively. The friction pads 23 are adapted to the anti-deviation plate 2 and the support plate 8 respectively. The friction pads 23 are made of wear-resistant rubber. Slide grooves 21 are provided on both ends of the outer walls of adjacent sides of the base 9. The length of the slide grooves 21 is less than the length of the base 9. Slider blocks 22 are provided on both outer walls of the support plate 8. The slide grooves 21 and the sliders 22 are both "T" shaped structures. The sliders 22 are slidably connected to the inner wall of the slide grooves 21. The support plates 8 seal the base 9, so that the bottom of the probe body 1 forms a flat bottom, expands the bottom space of the probe body 1, and makes the probe body 1 more stable.
[0030] The working principle of this practical application is as follows:
[0031] When the penetrometer body 1 is working, the anti-deviation plate 2 is connected to the penetrometer body 1. After the connection is completed, the positioning sleeve 3 set at the bottom of the anti-deviation plate 2 is inserted into the soil to fix the device. After the device is fixed, the rotating disk 5 at the top of the adjusting shaft 4 is rotated. Since the adjusting shaft 4 and the inner wall of the positioning sleeve 3 are connected by a threaded rotation, the rotation of the rotating disk 5 can drive the adjusting shaft 4 and the positioning sleeve 3 to rotate, thereby realizing the raising and lowering of the adjusting shaft 4. Since the anti-deviation plate 2 is located on both sides of the penetrometer body 1, and anti-deviation components are set at both ends of the anti-deviation plate 2, the device can be adjusted by adjusting the four sets of anti-deviation components. The horizontal position is adjusted. The cross level 7 set on the top of the anti-deviation plate 2 makes it easy to observe whether the penetrometer body 1 is in a horizontal state. Compared with the traditional penetrometer, the anti-deviation structure is set to correct the deviation of the penetrometer body 1, ensuring that the penetrometer body 1 is in a horizontal state when working, making the detection results more accurate. At the same time, the device is fixed by the positioning sleeve 3. When the height of the anti-deviation plate 2 is adjusted by the adjusting shaft 4, the positioning sleeve 3 will not rotate and affect the stability of the device. The protective plate 6 set on the outer wall of the positioning sleeve 3 protects the positioning sleeve 3 and prevents the entire positioning sleeve 3 from sinking into the soil and affecting the adjustment of the anti-deviation plate 2.
[0032] During the operation of the probe body 1, the probe 14 is connected to the mounting cylinder 13. Then, the servo motor 16 drives the threaded rod 15 to rotate, which drives the mounting plate 12 to descend, so that the probe 14 contacts the soil for detection. Compared with the traditional manual method of controlling the raising and lowering of the probe 14, the probe 14 can maintain a uniform speed and is more stable when the probe 14 applies pressure to the soil, which is conducive to improving the detection accuracy. When the mounting plate 12 moves up and down, the limiting groove 17 restricts the mounting plate 12 to ensure the stability of the up and down movement of the mounting plate 12, so that it will not shake during the up and down movement, and avoid affecting the operation of the probe 14.
[0033] When the probe body 1 is working, the anti-deviation structure is connected to it by a plug-in method, which makes it easier to carry the probe body 1 and the anti-deviation component and make it more convenient to use. The support plate 8 closes the base 9, so that the bottom of the probe body 1 forms a flat bottom, expands the bottom space of the probe body 1, and makes the probe body 1 more stable.
[0034] Finally, it should be noted that this application includes a controller and a power supply. The controller is used to control the electrical appliances, and the power supply is used to provide power. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model.
