Description

Technical Field

[0001] This application relates to the field of water conservancy engineering survey technology, and in particular to a portable three-axis three-lobed mold disassembly box. Background Technology

[0002] In the field of water conservancy engineering surveying, soil sample preparation is a crucial step in obtaining accurate soil mechanical parameters. To ensure the reliability of experimental data, the collected soil samples are typically compacted using a triaxial three-lobed mold to form an approximately cylindrical sample. The triaxial three-lobed mold, a common soil sample preparation tool, consists of three arc-shaped lobes that tightly conform to the soil sample and ensure its geometric regularity. This tool is widely used in soil mechanics testing, providing important reference data for engineering design and construction.

[0003] Under relevant technologies, common methods used in the industry for disassembling triaxial three-lobed molds include directly tapping the molds manually to achieve separation through vibration, and forcibly prying open the molds using pry bars or other hard tools. In addition, some methods attempt to reduce the friction between the soil and the molds by heating or applying lubricants, thereby facilitating mold disassembly. While these methods can solve the disassembly problem to some extent, they all have significant limitations.

[0004] Regarding the aforementioned technologies, the main drawback of existing technologies is their inability to effectively prevent damage to soil samples during disassembly. Manual tapping and the use of pry bars can easily lead to localized cracking or overall deformation of the sample, while heating or lubricating methods may alter the physical or chemical properties of the soil, thereby affecting the accuracy of experimental data. Furthermore, these methods are inefficient and cannot meet the demands of large-scale sample processing in modern engineering. Utility Model Content

[0005] To reduce damage to soil samples during demolding, this application provides a portable triaxial three-lobed mold disassembly box.

[0006] This application provides a portable triaxial three-lobed mold disassembly box, which adopts the following technical solution:

[0007] A portable triaxial three-lobed mold disassembly box includes a box body, disassembly components, and a three-lobed mold body;

[0008] The box body is open, with one side of the three-lobed mold body located inside the box body and the other side located outside the box body;

[0009] The three-lobed mold body includes three arc-shaped pieces, with two adjacent arc-shaped pieces fitting together, and the three arc-shaped pieces enclosing each other to form a sample preparation cavity;

[0010] The disassembly assembly includes a handle and a disassembly component. The handle is fixedly connected to the disassembly component, and one side of the disassembly component contacts the outer wall of the arc-shaped piece.

[0011] By adopting the above technical solution, the soil sample is located in the sample preparation cavity of the three-petal mold body. Before disassembly, the three-petal mold body is placed in the box, and the disassembly piece is tightly attached to the outer wall of the arc-shaped piece. When disassembling, the operator holds the handle and pushes the disassembly piece to push out one of the three-petal mold bodies. When the other two pieces need to be disassembled, the three-petal mold body is rotated, and the other two arc-shaped pieces are taken out in the same way. By holding the handle and sliding the disassembly piece, the three-petal mold body is further pushed out of the soil sample. The overall operation is simple and does not easily damage the soil.

[0012] Optionally, a through hole is provided on one side of the box body along a first direction, the through hole communicating with the inner cavity of the box body and the through hole communicating with the opening of the box body.

[0013] By adopting the above technical solution, in order to make it easier for personnel to place the three-petal mold body into the box, a through hole is provided on one side of the box body along the first direction. By setting the through hole, after one piece of the three-petal mold body is removed, it is convenient for personnel to rotate the three-petal mold body, and then push out the remaining two pieces until the entire three-petal mold body is taken out, and finally the sample can be taken out.

[0014] Optionally, the box body has a slot through two parallel sidewalls at the opening along a second direction, the second direction being perpendicular to the first direction, and the three-lobed mold body is fitted with a retaining ring, the retaining ring being located within the slot.

[0015] By adopting the above technical solution, during sample preparation, it is necessary to ensure that the three arc-shaped pieces are fixed structures while the soil sample is placed in the sample preparation cavity. For this purpose, the three-petal mold body is fitted with a retaining ring, which fixes the three arc-shaped pieces. Before demolding, in order to position the three-petal mold body in the box, the retaining ring is located in the second arc-shaped groove, so that the three-petal mold body is positioned by the second arc-shaped groove.

[0016] Optionally, the bottom wall of the box is inclined, and the bottom wall of the box is inclined towards the side near the through hole along the direction close to the opening of the box.

[0017] By adopting the above technical solution, in order to further facilitate demolding, the bottom wall of the box is inclined. The bottom wall of the box is inclined towards the side closer to the through hole along the direction close to the box opening. That is, the three-lobed mold body is also in an inclined state inside the box. When the three-lobed mold body is in an inclined state, the side of the disassembly part is attached to the outer wall of one of the three-lobed mold bodies. The personnel hold the handle and push the disassembly part towards the side away from the through hole to further push out the three-lobed mold body.

[0018] Optionally, the disassembly component has a first arc-shaped groove extending through it along a first direction on the side near the three-lobed mold body, and the wall of the first arc-shaped groove of the disassembly component fits against the outer wall of the three-lobed mold body.

[0019] By adopting the above technical solution, in order to further increase the contact area between the disassembled part and the arc-shaped piece, the first arc-shaped groove wall of the disassembled part is fitted with the outer wall of the three-lobed mold body, thereby making the disassembled part and the three-lobed mold body fit tightly together and the disassembly effect is better.

[0020] Optionally, a second arc-shaped groove is formed on the inner side wall of the box body away from the through hole along the second direction, and a permeable stone is provided in the second arc-shaped groove. The permeable stone is attached to one end wall of the three-lobed mold body.

[0021] By adopting the above technical solution, permeable stones are set up and adhere to the soil sample to prevent the soil sample from being carried away during demolding. Water generated during the squeezing of the soil sample can also be discharged through the permeable stones. In order to further position the permeable stones in the box, a second arc-shaped groove is opened on the side wall of the box, which can further limit the permeable stones and prevent them from shifting, thereby further reducing the displacement of the soil sample.

[0022] Optionally, the disassembly component is made of rubber.

[0023] By adopting the above technical solution, since the soil may contain natural cementing substances, such as clay minerals, organic matter, etc., these substances can further enhance the bonding force between soil particles. Therefore, in order to further improve the friction between the disassembly component and the three-lobed mold body and to reduce damage to the three-lobed mold body, the disassembly component is made of rubber.

[0024] Optionally, the handle includes a connecting rod and a gripping rod, the gripping rod being parallel to a first direction, and the connecting rod being fixedly connected between the gripping rod and the disassembly component.

[0025] By adopting the above technical solution, in order to further improve the comfort of personnel gripping, the personnel grip the handle, and the first arc-shaped groove of the disassembly part fits into an arc-shaped piece. The disassembly part is pushed in a downward tilting direction to push the arc-shaped piece to separate from the soil sample.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This application uses a box and disassembly components. Personnel hold the handle and push the disassembly component to push out one of the three-part mold body. When the other two parts need to be disassembled, the three-part mold body is rotated and the other two three-part molds are taken out in the same way. The operation is simple and does not easily damage the soil structure.

[0028] 2. This application features an inclined bottom wall inside the box to make it easier for personnel to slide and disassemble parts with less effort. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a portable triaxial three-lobed mold disassembly box. (Refer to...) Figure 1 and Figure 2 The portable triaxial three-lobed mold disassembly box includes a box body 1, a disassembly assembly 2, and a three-lobed mold body 3. The box body 1 is open-ended. In this embodiment, the box body 1 has a rectangular cross-section. One side of the three-lobed mold body 3 is located inside the box body 1, and the other side is located outside the box body 1. The disassembly assembly 2 includes a handle 21 and a disassembly component 22. The handle 21 is fixedly connected to the disassembly component 22, and one side of the disassembly component 22 contacts the outer wall of the three-lobed mold body 3. Before disassembly, the three-lobed mold body 3 is placed inside the box body 1, and the disassembly component 22 is pressed tightly against the outer wall of the three-lobed mold body 3. The operator holds the handle 21 and slides the disassembly component 22 to push out one of the three-lobed mold bodies 3. When it is necessary to disassemble the other two parts, the three-lobed mold body 3 is rotated, and the other two parts are taken out in the same way. The operation is simple and does not easily damage the soil structure.

[0038] Reference Figure 3The three-lobed mold body 3 includes three arc-shaped pieces 31. The three arc-shaped pieces 31 are joined together to form a hollow cylindrical structure. The three arc-shaped pieces 31 enclose a sample preparation cavity 311. A retaining ring 32 is fitted on the outer wall of the three-lobed mold body 3 to fix the three arc-shaped pieces 31. The soil sample is placed in the inner cavity of the three-lobed mold body 3 and compacted by a compactor. In order to protect the soil sample inside the three-lobed mold body 3, a permeable stone 33 is provided at one end of the three-lobed mold body 3. The permeable stone 33 is in contact with the soil sample to prevent the soil sample from being carried away during demolding. In addition, by setting the permeable stone 33, the water generated during the squeezing of the soil sample can also be discharged through the permeable stone 33. In this embodiment, the permeable stone 33 has a circular cross-section.

[0039] It should be noted that when the three-lobed mold body 3 is placed inside the box body 1, the three-lobed mold body 3 protrudes from the inner cavity of the box body 1.

[0040] Reference Figure 2 In order to further increase the contact area between the disassembly component 22 and the arc-shaped piece 31 so as to push the arc-shaped piece 31 out, a first arc-shaped groove 221 is provided through the side of the disassembly component 22 near the three-lobed mold body 3 along the first direction. The groove wall of the first arc-shaped groove 221 of the disassembly component 22 fits against the outer wall of the three-lobed mold body 3, so that the disassembly component 22 and the arc-shaped piece 31 fit tightly together and the disassembly effect is better.

[0041] Reference Figure 2 In some embodiments, the disassembly component 22 can be made of rubber or other flexible materials with high hardness. Since the soil may contain natural cementing substances, such as clay minerals, organic matter, etc., these substances can further enhance the bonding force between soil particles. Therefore, in order to further improve the friction between the disassembly component 22 and the three-lobed mold body 3 and to reduce damage to the three-lobed mold body 3, it is preferable that the disassembly component 22 is made of rubber in this embodiment.

[0042] Reference Figure 2 To facilitate the placement of the three-petal mold body 3 into the box body 1, a through hole 11 is provided on one side of the box body 1 along the first direction. The through hole 11 communicates with the inner cavity of the box body 1 and with the opening of the box body 1. Personnel can place the three-petal mold body 3 into the box body 1 through the through hole 11. By setting the through hole 11, after one arc-shaped piece 31 is disassembled, it is convenient for personnel to rotate the three-petal mold body 3 and then push out the remaining arc-shaped pieces 31 until all three arc-shaped pieces 31 are pushed out. Finally, the sample can be taken out.

[0043] Reference Figure 4To further facilitate demolding, the bottom wall of the box body 1 is inclined. The bottom wall of the box body 1 is inclined towards the side near the through hole 11 along the direction close to the opening of the box body 1. That is, the three-lobed mold body 3 is also inclined inside the box body 1. When the three-lobed mold body 3 is in an inclined state, one side of the disassembly part 22 is attached to an arc-shaped piece 31 of the three-lobed mold body 3. The personnel hold the handle 21 and push the disassembly part 22 towards the side away from the through hole 11, and further push out the arc-shaped piece 31.

[0044] Reference Figure 5 and Figure 6 Before demolding, in order to position the three-lobed mold body 3 inside the box body 1, the two parallel side walls of the box body 1 at the opening are provided with slots 12 through the second direction. The second direction is perpendicular to the first direction. The retaining ring 32 is located in the slots 12 so that the three-lobed mold body 3 can be positioned by the slots 12.

[0045] It should be noted that before demolding, the retaining ring 32 is fitted onto the three-lobed mold body 3, and the retaining ring 32 fixes the three arc-shaped pieces 31. When demolding, the retaining ring 32 needs to be removed first, and then the arc-shaped pieces 31 can be taken out through the disassembly part 22.

[0046] Reference Figure 6 During demolding, in order to further position the three-lobed mold body 3 and prevent the three-lobed mold body 3 from shifting during demolding, a second arc-shaped groove 13 is provided on the inner side wall of the box body 1 away from the through hole 11 along the second direction. The permeable stone 33 is located in the second arc-shaped groove 13. The three-lobed mold body 3 is in contact with the permeable stone 33, and the permeable stone 33 is aligned with the three-lobed mold body 3. The second arc-shaped groove 13 can also further limit the permeable stone 33, prevent the permeable stone 33 from shifting, and further reduce the displacement of soil samples.

[0047] Reference Figure 5 To further improve the comfort of gripping, the handle 21 includes a connecting rod 211 and a gripping rod 212. The gripping rod 212 is parallel to the first direction. The connecting rod 211 is fixedly connected between the gripping rod 212 and the disassembly component 22. When a person grips the gripping rod 212, the first arc-shaped groove 221 of the disassembly component 22 fits against an arc-shaped piece 31. The disassembly component 22 is pushed in a downward tilting direction to push the arc-shaped piece 31 to separate it from the soil sample.

[0048] The implementation principle of a portable triaxial three-lobed mold disassembly box according to an embodiment of this application is as follows: Before disassembly, the three-lobed mold body 3 is placed in the box body 1, the retaining ring 32 is located in the retaining groove 12 so that the three-lobed mold body 3 is positioned by the retaining groove 12, and the permeable stone 33 is placed in the second arc groove 13. The permeable stone 33 contacts the three-lobed mold body 3 and protects the soil sample by the permeable stone 33.

[0049] During demolding, the retaining ring 32 on the three-lobed mold body 3 will align one side of the disassembly piece 22 with one of the arc-shaped pieces 31 of the three-lobed mold body 3. The operator holds the handle 21 and pushes the disassembly piece 22 away from the through hole 11, further pushing out the arc-shaped piece 31. Then, the three-lobed mold body 3 is rotated so that the other arc-shaped piece 31 is above the box body 1. The above demolding steps are repeated until all three arc-shaped pieces 31 are removed.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
