[0034] like Figure 1-7 As shown, the present invention proposes a fixed mold installation device for concrete testing, which includes a fixed mold 4 with a cavity at the bottom and a movable plate 2. The fixed mold 4 is connected to the upper end face of the movable plate 2 through an alignment component.

[0035] A second moving mechanism is provided on one side of the upper end of the moving plate 2. A through limiting hole 22 is provided in the cavity at the bottom of the fixed mold 4 and facing the side of the second moving mechanism. A limiting block 17 that can be inserted into the limiting hole 22 is connected to the moving end of the second moving mechanism.

[0036] It also includes a mounting base 14 and a protective housing 10, which are mounted on the bottom of the protective housing 10. A first moving mechanism is provided between the mounting base 14 and the inner wall of the protective housing 10, and the moving end of the first moving mechanism is connected to the bottom of the moving plate 2.

[0037] It also includes multiple wheels 1, which are mounted on the bottom of the movable plate 2. The bottom of the protective shell 10, the bottom of the mounting base 14, and the bottom of the wheels 1 are on the same plane.

[0038] The fixed mold 4 is used to carry concrete test samples, and the movable plate 2 provides a basic platform for the installation of the fixed mold 4. The two are precisely aligned and connected through the alignment component.

[0039] In this invention, when in use, the concrete to be tested is poured into mold 4, and then the concrete sample to be tested is poured into the fixed mold 4. Subsequent testing operations are carried out in accordance with the relevant standards and procedures for concrete testing (the tests include, but are not limited to, using the water pressure method to determine the permeability coefficient of the concrete).

[0040] During the testing process, it can effectively prevent the fixed mold 4 from shifting or shaking, ensuring the accuracy of the test results.

[0041] Furthermore, when replacing the fixed mold 4, the second moving mechanism drives the limiting block 17 out of the alignment groove 22, thereby removing the limiting effect on the fixed mold 4. Then, the fixed mold 4 is removed from the moving plate 2, and the fixed mold 4 that needs to be used is installed on the moving plate 2 through the alignment assembly. Finally, the second moving mechanism is started again to drive the limiting block 17 into the limiting hole 22, thereby limiting the fixed mold 4 and facilitating the replacement of different fixed molds 4.

[0042] After use, the first moving mechanism is activated. The first moving mechanism can drive the moving plate 2 to move into the protective shell 10, which can prevent the moving plate 2 and the components above the moving plate 2 from being damaged by external collisions.

[0043] When the movable plate 2 moves into the protective housing 10, the stability of the movable plate 2 is ensured by multiple wheels 1.

[0044] In an optional embodiment, the alignment component includes a bottom block 20 installed in the inner cavity of the fixed mold 4, and an alignment groove 21 formed at the bottom of the bottom block 20. An alignment block 23 that can cooperate with the alignment groove 21 is installed on the upper surface of the movable plate 2.

[0045] It should be noted that when the 4 is to be used, the alignment block 23 on the upper end face of the movable plate 2 is aligned with the alignment groove 21 at the bottom of the inner cavity bottom block 20 of the fixed mold 4. Since the alignment block 23 and the alignment groove 21 have a cross-shaped structure and the edge of the upper end face of the alignment block 23 is inclined, the inclined surface can play a guiding role during the placement process, helping to quickly and accurately insert the alignment block 23 into the alignment groove 21, and complete the initial alignment of the fixed mold 4 and the movable plate 2.

[0046] In an optional embodiment, the alignment block 23 and the alignment groove 21 are in a cross shape, and the edge of the upper surface of the alignment block 23 is an inclined surface.

[0047] It should be noted that the design of the upper edge of the alignment block 23 being inclined enables the alignment block 23 and the alignment groove 21 to be quickly aligned, which facilitates the quick alignment of the fixed mold 4.

[0048] In an optional embodiment, the second moving mechanism includes a side plate 8 mounted on the upper surface of the moving plate 2, a connecting plate 5 connected to the side of the limiting block 17 away from the central axis of the fixed mold 4, a threaded sleeve 19 passing through the middle of the side plate 8, the threaded sleeve 19 being threadedly connected to the outer surface of the first threaded rod 7, one end of the first threaded rod 7 being rotatably connected to the connecting plate 5, and the other end of the first threaded rod 7 being coaxially fixed to the first throttle 9, and also includes stabilizing components located on both sides of the first threaded rod 7 for connecting the connecting plate 5 and the side plate 8.

[0049] It should be noted that by rotating the first throttle 9, the first threaded rod 7 is driven to rotate. Since the threaded sleeve 19 is threaded to the outer surface of the first threaded rod 7 and passes through the middle of the side plate 8, the rotation of the first threaded rod 7 can drive the first threaded rod 7 and the connecting plate 5 to move to one side of the fixed mold 4 through the threaded sleeve 19, thereby driving the limiting block 17 connected to the connecting plate 5 to move.

[0050] In an optional embodiment, the stabilizer includes a first slide rod 6 that slides through the middle of the side plate 8, a limiting ring 18 connected to one end of the first slide rod 6, and the other end of the first slide rod 6 connected to the connecting plate 5. The first threaded rod 7 is parallel to the first slide rod 6. The stabilizer can ensure the stability of the connecting plate 5 during movement and prevent shaking.

[0051] It should be noted that when the connecting plate 5 is moving, it can slide through the side plate 8 via the first sliding rod 6 connected to it, ensuring the stability of the movement of the connecting plate 5; and the limiting ring 18 ensures that the first sliding rod 6 will not detach from the side plate 8.

[0052] In an optional embodiment, the first moving mechanism includes a second threaded rod 11 that passes through the rear end face of the protective housing 10 via a bearing in the middle. One end of the second threaded rod 11 is coaxially fixed to the second throttle 13, and the other end is connected to the inner wall of the mounting base 14. A second moving block 16 is threaded onto the outer surface of the second threaded rod 11 and connected to the bottom of the moving plate 2.

[0053] It should be noted that by rotating the second throttle 13, the second threaded rod 11 can be rotated, causing the second moving block 16 to move on the second threaded rod 11, thereby realizing the movement of the moving plate 2, which facilitates the adjustment of the position of the fixed mold 4.

[0054] In an optional embodiment, it further includes a second slide rod 12 located on both sides of the second threaded rod 11 and used to connect the protective housing 10 and the inner wall of the mounting base 14, and a first moving block 15 slidably sleeved on the outer surface of the second slide rod 12 and connected to the bottom of the moving plate 2.

[0055] It should be noted that when the movable plate 2 is moving, the second movable block 16 at the bottom of the movable plate 2 will slide on the second sliding rod 12 connected to it, ensuring the stability of the movement of the movable plate 2.

[0056] In an optional embodiment, a limiting plate 3 is installed on the upper surface of the movable plate 2 at a position away from the second moving mechanism. The limiting plate 3 can cooperate with the outer surface of the fixed mold 4.

[0057] It should be noted that the limiting plate 3 on the upper end of the movable plate 2 cooperates with the outer surface of the fixed mold 4 to play an auxiliary role in fixing.

[0058] Working principle:

[0059] Place the mounting base 14 stably in the appropriate position for testing, ensuring that the bottom of the protective shell 10, the mounting base 14, and the wheel 1 are on the same plane;

[0060] At this time, by rotating the second handle 13, the second threaded rod 11 can be driven to rotate, thereby driving the second moving block 16 to move on the second threaded rod 11, so that the moving plate 2 moves outward along the second slide rod 12 and adjusts the moving plate 2 to the working position.

[0061] The concrete sample to be tested is poured into the fixed mold 4, and subsequent testing operations are carried out in accordance with the relevant standards and procedures for concrete testing. During the testing process, the fixed mold 4 can be effectively prevented from shifting or shaking, ensuring the accuracy of the test results.

[0062] When it is necessary to replace 4, first turn the first handle 9 to make the limiting block 17 exit from the limiting hole 22 of the fixed mold 4, release the limitation on the fixed mold 4, and then take the fixed mold 4 upward to separate the alignment block 23 from the alignment groove 21, so that the fixed mold 4 can be disassembled.

[0063] Then, when the 4th step is needed, align the alignment block 23 on the upper surface of the movable plate 2 with the alignment groove 21 at the bottom of the inner cavity bottom block 20 of the fixed mold 4. Since the alignment block 23 and the alignment groove 21 have a cross-shaped structure and the edge of the upper surface of the alignment block 23 is inclined, the inclined surface can play a guiding role during the placement process, helping to quickly and accurately insert the alignment block 23 into the alignment groove 21, and complete the initial alignment of the fixed mold 4 and the movable plate 2.

[0064] After the fixed mold 4 is initially aligned, the first screw rod 7 is rotated by turning the first handle 9. Since the threaded sleeve 19 is threaded to the outer surface of the first screw rod 7 and passes through the middle of the side plate 8, the rotation of the first screw rod 7 can drive the first screw rod 7 and the connecting plate 5 to move to one side of the fixed mold 4 through the threaded sleeve 19. This will drive the limiting block 17 connected to the connecting plate 5 to move. When the limiting block 17 is inserted into the limiting hole 22 at the bottom of the fixed mold 4, and the connecting plate 5 abuts against the outer surface of the fixed mold 4, the first handle 9 is stopped, thereby limiting and fixing the fixed mold 4. At the same time, the limiting plate 3 on the upper end of the moving plate 2 cooperates with the outer surface of the fixed mold 4 to play an auxiliary fixing role, thereby facilitating the replacement of the fixed mold 4.

[0065] After use, by rotating the second handle 13, the second threaded rod 11 is driven to rotate, causing the second moving block 16 to move on the second threaded rod 11, thereby enabling the moving plate 2 and the fixed mold 4 to move into the protective shell 10. Thus, the protective shell 10 can prevent the moving plate 2 and the components above the moving plate 2 from being damaged by external collisions.

[0066] When the movable plate 2 is moving, the multiple wheels 1 at the bottom of the movable plate 2 improve the stability of the movement.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
