Detailed Implementation

[0018] Example 1

[0019] like Figure 1 , Figure 3 and Figure 4 As shown, the present invention proposes a roadbed settlement detection device, including a base 1, a level 7, a leveling mechanism, and a stabilizing mechanism; a measuring rod 2 is detachably installed on the top of the base 1, and a detection end is detachably installed on the top of the measuring rod 2; the level 7 is located at the top of the base 1; the leveling mechanism is located at the middle of the bottom end of the base 1, and the leveling mechanism consists of a mounting seat 3 installed at the bottom end of the base 1, a ball 301 rotatably connected to the inner cavity of the mounting seat 3, and two sets of first threaded rods 302 symmetrically threaded on the mounting seat 3. And one end of the inner cavity abuts against the mounting base 3; the stabilizing mechanism consists of a stabilizing rod 4 installed at the bottom of the ball 301, a driving assembly set in the mounting cavity inside the stabilizing rod 4, an insert rod 601 slidably connected to the mounting cavity, and an elastic element 602. The stabilizing rod 4 has a through hole 402, which communicates with the mounting cavity. The insert rod 601 is driven by the driving assembly to adjust its displacement along the through hole 402. One end of the elastic element 602 is connected to the inner wall of the stabilizing rod 4, and the other end is connected to the end of the insert rod 601 that is away from the through hole 402.

[0020] Furthermore, the inner cavity of the mounting base 3 consists of a spherical cavity and two sets of receiving cavities. The two sets of receiving cavities are symmetrically distributed on both sides of the spherical cavity and communicate with it. The sphere 301 is rotatably connected to the spherical cavity. The abutting end of the first threaded rod 302 is provided with an anti-slip block 303, which is distributed in the receiving cavity. The anti-slip block 303 increases the friction at the abutting point between the first threaded rod 302 and the sphere 301, preventing slippage.

[0021] Furthermore, a transmission block 6 is installed on the end of the insertion rod 601 away from the through hole 402. The bottom end of the transmission block 6 is slidably connected to the bottom end of the mounting cavity inside the stabilizer rod 4, which facilitates the guidance of the movement direction of the insertion rod 601, so that it moves and adjusts stably along the through hole 402. The elastic element 602 is a spring, which is sleeved on the outside of the insertion rod 601 and installed between the transmission block 6 and the inner wall of the stabilizer rod 4.

[0022] Furthermore, three sets of through holes 402 are provided, and the three sets of through holes 402 are evenly distributed on the outer circumferential surface of the stabilizer 4. Three sets of insertion rods 601 are provided corresponding to the through holes 402. The setting of multiple sets of insertion rods 601 can improve the stability of the connection between the stabilizer 4 and the bottom of the pit, and prevent the base 1 and the measuring rod 2 from tilting.

[0023] Furthermore, the adjustment assembly includes an adjustment rod 5, a second threaded rod 501, and a drive block 502; the adjustment rod 5 is rotatably connected to the stabilizer rod 4, and a threaded seat is threadedly connected to the adjustment rod 5, which abuts against the outer circumferential surface of the stabilizer rod 4 to limit the adjustment rod 5 and prevent it from rotating under non-external force adjustment; the second threaded rod 501 is rotatably connected to the top of the internal mounting cavity of the stabilizer rod 4, and a transmission component is provided between the second threaded rod 501 and the adjustment rod 5, the transmission component consisting of two sets of bevel gears; the drive block 502 is threadedly connected to the second threaded rod 501, and the slide rod 5... 03. The drive block 502 is adjusted by sliding along the height direction of the mounting cavity inside the stabilizer bar 4. The side wall of the mounting cavity of the stabilizer bar 4 is provided with a guide groove 401. The drive block 502 is provided with a slide rod 503. The other end of the slide rod 503 is slidably connected to the guide groove 401. By setting the slide rod 503 and the guide groove 401, the drive block 502 can only be adjusted vertically along the mounting cavity and cannot rotate. The drive block 502 is composed of a sleeve and a conical platform installed at the bottom of the sleeve. The sleeve is threadedly connected to the second threaded rod 501. The setting of the conical platform makes it easy to gradually push multiple sets of transmission blocks 6 in a direction away from each other.

[0024] In this embodiment, initially, the insertion rod 601 is positioned inside the installation cavity. The stabilizing rod 4 is inserted deep into the bottom of the pit, initially limiting the base 1 and measuring rod 2. Rotating the adjusting rod 5 causes the second threaded rod 501 to rotate under the transmission action of two sets of bevel gears. Guided by the sliding rod 503 and the guide groove 401, the driving block 502 moves downward along the installation cavity until it is inserted between multiple sets of transmission blocks 6, pushing the multiple sets of transmission blocks 6 in a direction away from each other, causing the corresponding elastic element 602 to be squeezed. At the same time, the transmission block 6 slides along the bottom of the installation cavity, driving the insertion rod 601 to slide outward along the through hole 402 until it is inserted into the soil around the stabilizing rod 4, further improving the installation stability of the stabilizing rod 4 and preventing the base 1 and measuring rod 2 from being inserted into the soil around the stabilizing rod 4. The measuring rod 2 is tilted relative to the foundation pit without external force adjustment to prevent interference. After the stabilizing mechanism is installed, the handle of the first threaded rod 302 is rotated to make it rotate along the mounting base 3, which can drive the anti-sliding block 303 to move into the corresponding storage cavity. At this time, the ball 301 is no longer restricted relative to the spherical cavity of the mounting base 3. The ball 301 can rotate along the mounting base 3 at a suitable angle. With the cooperation of the level 7, the base 1 is rotated at a suitable angle until the base 1 is adjusted to a horizontal position, making the adjustment more convenient and quick. After the adjustment is completed, the first threaded rod 302 is rotated in the opposite direction to make the anti-sliding block 303 move into the spherical cavity and press against the ball 301. The two sets of first threaded rods 302 stabilize and limit the ball 301 and the base 1 to prevent the measuring rod 2 on the base 1 from tilting relative to the foundation pit without external force adjustment.

[0025] Example 2

[0026] like Figure 1 and Figure 2 As shown, the roadbed settlement detection device proposed in this utility model, compared with the first embodiment, has a connecting seat 101 installed at the top of the base 1, a threaded part provided at the bottom of the outer peripheral surface of the measuring rod 2, the threaded part being threadedly connected to the connecting seat 101, and a stabilizing frame 201 also provided on the measuring rod 2, the bottom end of the stabilizing frame 201 abutting against the top of the base 1.

[0027] In this embodiment, before adjusting the stabilizing mechanism and the leveling mechanism, the measuring rod 2 can be separated from the base 1 to reduce the overall weight of the base 1, lower the center of gravity of the base 1, and make it easier to adjust the base 1. After adjusting the base 1 to be horizontal relative to the pit, the threaded part of the measuring rod 2 is connected to the internal thread of the connecting seat 101 until the bottom end of the stabilizing frame 201 is pressed against the base 1, which improves the connection stability between the measuring rod 2 and the base 1, so that the measuring rod 2 and the base 1 remain in a vertical state, thereby improving the detection efficiency.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
