Description

Technical Field

[0001] This utility model belongs to the field of spreading test of solidified soil, and in particular relates to a horizontal adjustment structure and a test device for measuring the spreading of solidified soil. Background Technology

[0002] Solidified soil is a soil material with a certain strength obtained by solidifying soil particles with cement or other solidifying agents. Fluidized solidified soil refers to pre-mixed solidified soil with a certain fluidity that can be poured for construction. Fluidized solidified soil is mainly used in the field of roadbed, building foundation and other reinforcement treatment. Before using fluidized solidified soil for corresponding construction, it is often necessary to measure the spread of the fluidized solidified soil to ensure the construction quality.

[0003] When measuring the spreadability of solidified soil, it is essential to ensure the levelness of the measuring platform to guarantee the accuracy of the experimental spreadability. Existing technologies, such as patent CN219475289U, disclose a structure for measuring the flowability of fluidized solidified soil. This structure includes leveling components at the four corners of a square plate. These components consist of threaded sleeves and threaded rods, allowing adjustment of the length of the threaded rod extending into the threaded sleeve to adjust the levelness of the square plate. However, in this method, since the threaded sleeve is fixedly connected to the bottom of the square plate, its primary function during adjustment is to ensure the square plate is in contact with the platform or ground where the test structure is placed, allowing it to rest stably on the platform or ground. Adjusting the levelness of the square plate is limited, especially when the platform or ground itself has a certain degree of inclination, making leveling even more difficult. Utility Model Content

[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0022] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0023] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0024] Please see Figure 1-2This utility model provides a horizontal adjustment structure, including: a measuring platform 1, a base 2, at least three spaced-apart support mechanisms 4, and at least three spaced-apart first leveling mechanisms 3; the top surface of the measuring platform 1 provides an experimental space for the solidified soil to be tested. The support mechanisms 4 are spaced-apart on the bottom surface of the base 2 to support the base 2 on the platform or the ground; one end of the first leveling mechanism 3 is connected to the top surface of the base 2, and the other end is rotatably connected to the bottom of the measuring platform 1 to adjust the levelness of the measuring platform 1; the first leveling mechanism 3 includes a first fixing member 31 and a telescopic component 32, the first fixing member 31 is set on the bottom surface of the measuring platform 1, and a first spherical groove is provided inside it; one end of the telescopic component 32 is provided with a first spherical structure 33 rotatably connected in the first spherical groove, and the other end of the telescopic component 32 is connected to the top surface of the base 2; the telescopic component 32 adjusts the levelness of the measuring platform 1 by changing its own length to drive the measuring platform 1 to rotate relative to the horizontal plane.

[0025] In this embodiment, the measuring platform 1 and the base 2 can each be a disc 326 structure, and there are three support mechanisms 4 and three first leveling mechanisms 3. The three support mechanisms 4 and the three leveling mechanisms form an equilateral triangle structure, which can ensure the stability of the measuring platform 1 and the base 2.

[0026] The first fixing member 31 may include a first fixing sub-member and a second fixing sub-member. One end of the first fixing sub-member and the second fixing sub-member are detachably connected to the bottom of the measuring platform 1, and the other end is respectively provided with a first spherical sub-groove. When the first fixing sub-member and the second fixing sub-member are both set at the bottom of the measuring platform 1, the first fixing sub-member and the second fixing sub-member form a boss-shaped structure, and the two first spherical sub-grooves form a first spherical groove, so that the first spherical structure 33 can be installed and limited into the first spherical groove.

[0027] During use, the change in the length of one of the telescopic components 32 causes the first spherical structure 33 to slide within the first spherical groove, thereby driving the measuring platform 1 to rotate with the other two telescopic components 32 as support points, thus adjusting the level of the measuring platform 1 and ensuring that the expansion of the solidified soil to be tested can be accurately obtained.

[0028] Please see Figure 2In one implementation, the telescopic assembly 32 may include a first support rod 321 and a first support sleeve 322. A first spherical structure 33 is disposed at one end of the first support rod 321, and the other end of the first support rod 321 is rotatably disposed within the first support sleeve 322. The end of the first support sleeve 322 away from the first support rod 321 is connected to the top surface of the base 2. By changing the length of the first support rod 321 extending out of the first support sleeve 322, the measuring platform 1 is rotated relative to the horizontal plane, thereby adjusting the levelness of the measuring platform 1. Specifically, the end of the first support sleeve 322 away from the first support rod 321 is fixedly connected to the top surface of the base 2, and the other end is provided with an internal thread. The end of the first support rod 321 extending into the first support sleeve 322 is provided with an external thread, thus the first support rod 321 and the first support sleeve 322 are threadedly connected. In use, since both ends of the first support rod 321 are rotatably connected, rotating the first support rod 321 can change the length of the first support rod 321 extending out of the first support sleeve 322, thereby driving the measuring platform 1 to rotate.

[0029] Please see Figure 1 , 3 -4. In another implementation, the telescopic assembly 32 may further include a second support rod 323, a third support rod 324, and a connector 325; a first spherical structure 33 is disposed at one end of the second support rod 323, the other end of the second support rod 323 is rotatably connected to the connector 325, and the length of the second support rod 323 extending into the connector 325 is adjustable; the end of the connector 325 away from the second support rod 323 is rotatably connected to the third support rod 324, the end of the third support rod 324 away from the connector 325 is connected to the upper top surface of the base 2, and the length of the end of the third support rod 324 extending into the connector 325 is not adjustable; the second support rod 323, by changing its length extending into the connector 325, drives the measuring platform 1 to rotate relative to the horizontal plane, thereby adjusting the levelness of the measuring platform 1. Specifically, connector 325 includes a first sub-connector 3251 and a second sub-connector 3252. One end of the first sub-connector 3251 is provided with a first receiving cavity 32511, and the inner wall of the first receiving cavity 32511 is provided with an internal thread. The end of the second support rod 323 without the first spherical structure 33 is provided with an external thread, that is, the second support rod 323 and the first receiving cavity 32511 are threadedly connected. The other end of the first sub-connector 3251 is provided with a second receiving cavity 32512.

[0030] The second sub-connector 3252 includes a first hole 32521, a second hole 32522, and a third hole 32523. The second hole 32522 is located between the first hole 32521 and the third hole 32523. The diameter of the second hole 32522 is smaller than the diameter of the first hole 32521, and the diameter of the third hole 32523 is smaller than the diameter of the second hole 32522. The first hole 32521, the second hole 32522, and the third hole 32523 are connected. The outer side wall of the end of the first sub-connector 3251 where the second receiving cavity 32512 is provided with an external thread, and the first hole 32521 is provided with an internal thread, that is, the first sub-connector 3251 is threadedly connected to the inner side wall of the first hole 32521. A disc 326 is provided at the connection end between the third support rod 324 and the connector 325. The disc 326 is located within the space formed by the second receiving cavity 32512 and the second hole 32522. The third hole 32523 is used for the third support rod 324 to pass through. The thickness of the disc 326 can be less than or equal to the sum of the depth of the second hole 32522 and the depth of the second receiving cavity 32512, and the diameter of the disc 326 can be less than or equal to the diameter of the second hole 32522 and the second receiving cavity 32512, thereby enabling the disc 326 to be rotatably connected within the space formed by the second hole 32522 and the second receiving cavity 32512.

[0031] In use, a certain gripping force can be applied to the second support rod 323 to prevent it from rotating. Then, by applying a certain rotational force to the first sub-connector 3251, the length of the second support rod 323 extending beyond the first sub-connector 3251 can be changed, thereby adjusting the levelness of the measuring platform 1. It is understood that the thread direction connecting the first sub-connector 3251 and the second sub-connector 3252 is opposite to the thread direction connecting the first sub-connector 3251 and the second support rod 323, thus preventing the second sub-connector 3252 from disengaging from the first sub-connector 3251 when the first sub-connector 3251 is rotated.

[0032] In this embodiment, the first sub-joint 3251 and the second sub-joint 3252 enable the second support rod 323 to be rotatably connected to the first sub-joint 3251, allowing the length extending out of the first sub-joint 3251 to be changed. The third support rod 324 is also rotatably connected to the second sub-joint 3252, while the length of the third support rod 324 extending out of the second sub-joint 3252 remains constant. This allows for adjustment of the levelness of the measuring platform 1 and prevents excessive rotation of the second support rod 323 between the first spherical structure 33 and the first spherical groove when adjusting the length extending out of the telescopic joint 325. This would increase wear on the first spherical structure 33 and the first spherical groove, thus preventing the first spherical structure 33 from detaching from the first spherical groove.

[0033] The horizontal adjustment structure also includes a second leveling mechanism 5. One end of the second leveling mechanism 5 is rotatably connected to the middle of the bottom surface of the measuring platform 1, and the other end is connected to the middle of the top surface of the base 2. Specifically, the second leveling mechanism 5 includes a second fixing member 51 and a fourth support rod 52. The second fixing member 51 is disposed on the bottom surface of the measuring platform 1, and a second spherical groove is provided inside the second fixing member 51. The fourth support rod 52 is connected to the top surface of the base 2, specifically by a fixed connection achieved by bolts or screws, etc., and the other end is provided with a second spherical structure 53 rotatably connected in the second spherical groove. In this embodiment, the central axis of the fourth support rod 52 coincides with the central axis of the measuring platform 1 and the base 2, and coincides with the perpendicular bisector of the equilateral triangle formed by the three first leveling mechanisms 3 and the perpendicular bisector of the equilateral triangle formed by the three support mechanisms 4.

[0034] The second fixing member 51 may include a third fixing sub-member and a fourth fixing sub-member. One end of the third fixing sub-member and the fourth fixing sub-member are detachably connected to the bottom of the measuring platform 1, and the other end is respectively provided with a second spherical sub-groove. When the third fixing sub-member and the fourth fixing sub-member are both set at the bottom of the measuring platform 1, the third fixing sub-member and the fourth fixing sub-member form a boss-shaped structure, and the two second spherical sub-grooves form a second spherical groove, so that the second spherical structure 53 can be installed and limited into the second spherical groove.

[0035] The support mechanism 4 may include a fifth support rod 41 and a second support sleeve 42. One end of the second support sleeve 42 is disposed on the bottom surface of the base 2, and the fifth support rod 41 is threadedly connected to the end of the second support sleeve 42 away from the base 2. Specifically, the second support sleeve 42 may be provided with internal threads, and the fifth support member may be provided with external threads, thereby realizing a threaded connection.

[0036] In use, the base 2 and the measuring platform 1 are first securely installed onto a table or ground using the support mechanism 4. The table can be the top surface of a table or similar structure, or it can be the top surface of a steel plate or similar structure laid on the ground. This embodiment does not impose any restrictions on this. Furthermore, the measuring platform 1 can be brought to a near-horizontal state by adjusting the support mechanism 4, and then the measuring platform 1 can be brought to a horizontal state by using the first adjustment mechanism.

[0037] Another aspect of this embodiment provides a testing device for measuring the spreadability of solidified soil, including a horizontal adjustment structure as described above, two telescopic drive members 6 and two wrapping members 7. The two telescopic drive members 6 are spaced apart on the measuring platform 1, and each wrapping member 7 corresponds to the movable end of one telescopic drive member 6. The telescopic drive member 6 drives the corresponding wrapping member 7 to move, so that the two wrapping members 7 enclose each other to form a hollow conical cylinder for accommodating the solidified soil to be tested. The telescopic drive member 6 can be a telescopic drive element such as a cylinder or an electric cylinder, and this embodiment does not limit this. The wrapping member 7 can be a structure formed by splitting the hollow conical cylinder in half. In use, the two telescopic drive members 6 drive the corresponding wrapping member 7 to move, so that the two wrapping members 7 enclose each other to form a hollow conical cylinder for accommodating the solidified soil to be tested. After the solidified soil is loaded, the two telescopic drive members 6 drive the corresponding wrapping members 7 to move in opposite directions, thereby starting the spreadability test of the solidified soil.

[0038] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0039] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
