Description

Technical Field

[0001] This utility model relates to the field of cement stability testing technology, specifically to a Le Chatelier clamp demolding device. Background Technology

[0002] In the test of cement soundness in building materials, a Le Chatelier clamp is required. The Le Chatelier clamp consists of a ring mold and two pointers. There is a longitudinal slit on the side of the ring mold between the two pointers. The test involves filling the ring mold with cement paste of standard consistency, smoothing both ends, covering it with a glass plate, curing it in a curing room for one day, and then boiling it in boiling water for 3 hours. After boiling, the cement paste has hardened into cement blocks and has expanded slightly compared to before boiling. The longitudinal slit will open slightly, but the expansion value is very small. Therefore, the expansion value is measured by the pointer to determine whether the cement soundness is qualified.

[0003] Currently, after the cement stability test is completed, the cement block inside the ring mold needs to be removed. Because the ring mold has no stress points and the pointer cannot be turned, removing the cement block from the ring mold has become a difficult point, which is time-consuming, labor-intensive, and easily damages the Le Chatelier clamp. Utility Model Content

[0004] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a Le Chatelier clamp demolding device, which solves the problem that after the cement stability test is completed, it is difficult to remove the cement block from the ring mold. Because the ring mold has no stress point and the pointer cannot be turned, removing the cement block from the ring mold is a difficult, time-consuming, and labor-intensive process, and may damage the Le Chatelier clamp.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A Le Chatelier clamp release device, capable of clamping a Le Chatelier clamp, includes: a mold sleeve, the mold sleeve having a first chamber and a second chamber, the first chamber and the second chamber being interconnected, the inner diameter of the first chamber being greater than or equal to the outer diameter of the Le Chatelier clamp, the inner diameter of the second chamber being less than the outer diameter of the Le Chatelier clamp, and the inner diameter of the second chamber being greater than or equal to the inner diameter of the Le Chatelier clamp; the first chamber being capable of clamping the Le Chatelier clamp, and a limiting platform being formed at the connection between the second chamber and the first chamber, the limiting platform contacting one end of the Le Chatelier clamp.

[0007] As a preferred embodiment, the mold includes two arc-shaped clamps with the same radius, which are connected in an openable manner. Each arc-shaped clamp includes a first wall thickness section and a second wall thickness section, with the wall thickness of the first wall thickness section being less than that of the second wall thickness section. The first wall thickness sections of the two arc-shaped clamps correspond to each other to form a first chamber, and the second wall thickness sections of the two arc-shaped clamps correspond to each other to form a second chamber.

[0008] As a preferred embodiment, one end of the two arc-shaped clips is hinged, and the other end of the two arc-shaped clips is connected and fixed by a connector.

[0009] As a preferred embodiment, the connector includes a first connecting block, a second connecting block, and a screw sleeve assembly. The first connecting block and the second connecting block are respectively fixedly connected to two arc-shaped clamping pieces, and the screw sleeve assembly is respectively connected to the first connecting block and the second connecting block.

[0010] As a preferred embodiment, the connector also includes a spring, which is sleeved on the outside of the screw sleeve assembly and located between the first connecting block and the second connecting block.

[0011] As a preferred option, one end of the two curved clips is hinged together by a hinge.

[0012] As an alternative, a striking rod is also included, which is inserted into the Le Chatelier clamp to push out the cement block.

[0013] In summary, this utility model has the following advantages:

[0014] The Le Chatelier clamp demolding device of this utility model can easily remove the cement block from the Le Chatelier clamp and ensure that the Le Chatelier clamp is not damaged. First, the Le Chatelier clamp demolding device is placed in a tray. By fixing the screw sleeve, any one of the arc-shaped clamps is slightly opened, and the Le Chatelier clamp is placed into the first chamber, with one end of the Le Chatelier clamp in contact with the limiting platform. Tighten the fixing screw sleeve so that the inner walls of the two arc-shaped clamps are in contact with the Le Chatelier clamp. The cement block inside the Le Chatelier clamp is struck by the striking rod. The limiting platform limits the Le Chatelier clamp. Under the strike of the striking rod, the cement block falls out of the Le Chatelier clamp, passes through the second chamber and falls into the tray. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-5As shown, this embodiment provides a Red Crust clamp 4 demolding device. The Red Crust clamp 4 demolding device can clamp the Red Crust clamp 4 and includes: a mold sleeve 1, the mold sleeve 1 having a first chamber and a second chamber, the first chamber and the second chamber being interconnected, the inner diameter of the first chamber being greater than or equal to the outer diameter of the Red Crust clamp 4, the inner diameter of the second chamber being less than the outer diameter of the Red Crust clamp 4, and the inner diameter of the second chamber being greater than or equal to the inner diameter of the Red Crust clamp 4; the first chamber can clamp the Red Crust clamp 4, and a limiting platform 5 is formed at the connection between the second chamber and the first chamber, the limiting platform 5 being in contact with one end of the Red Crust clamp 4.

[0023] In some embodiments, the mold sleeve 1 includes two arc-shaped clamps with the same radius, which are connected in an openable manner. Each arc-shaped clamp includes a first wall thickness section and a second wall thickness section, the first wall thickness section being less than the second wall thickness section. The first wall thickness sections of the two arc-shaped clamps correspond to each other to form a first chamber, and the second wall thickness sections of the two arc-shaped clamps correspond to each other to form a second chamber. By designing the wall thickness difference, the inner wall of the arc-shaped clamps forms a step, with the plane of the step serving as a limiting platform 5. When the concrete block inside the Le Chatelier clamp 4 is struck, the limiting platform 5 supports the ring mold of the Le Chatelier clamp 4. Under the force of the limiting platform 5, the concrete block inside the Le Chatelier clamp 4 can be easily knocked out.

[0024] In some embodiments, one end of the two arc-shaped clips is hinged, and the other end of the two arc-shaped clips is connected and fixed by a connector.

[0025] In some embodiments, the connector includes a first connecting block, a second connecting block, and a screw sleeve assembly 2. The first and second connecting blocks are respectively fixedly connected to two arc-shaped clamping pieces, and the screw sleeve assembly 2 is connected to the first and second connecting blocks respectively. Both the first and second connecting blocks are rectangular blocks, and are respectively fixed to the opposite side edges of the two arc-shaped clamping pieces. The first and second connecting blocks are provided with connecting holes. The screw sleeve assembly 2 includes a bolt and a nut. The shank of the bolt passes through the connecting hole of the first and second connecting blocks, and the nut is threadedly connected to the bolt to clamp the first and second connecting blocks, so that the two arc-shaped clamping pieces clamp the Le Chatelier clamp 4.

[0026] In some embodiments, the connector further includes a spring 3, which is sleeved on the outside of the screw sleeve assembly 2 and located between the first connecting block and the second connecting block. Specifically, the spring's function is to allow the arc-shaped clamp to open when the screw sleeve assembly 2 is loosened, thereby allowing the Le Chatelier clip to be removed.

[0027] In some embodiments, one end of the two arc-shaped clips is hinged by a hinge 6. There are two hinges 6, which are spaced apart along the side edge of the arc-shaped clips and are fixedly connected to the arc-shaped clips by screws.

[0028] The demolding device of the Le Chatelier clamp 4 in this embodiment also includes a striking rod 7, which is used to insert into the Le Chatelier clamp 4 to push out the cement block. Specifically, the striking rod 7 is a solid structure, and the cross-section of the striking end that contacts the cement block in the Le Chatelier clamp 4 is a trapezoidal structure, while the cross-section of the end away from the Le Chatelier clamp 4 is an inverted trapezoidal structure.

[0029] Working principle: First, the Le Chatelier clamp 4 demolding device is placed in the tray. By using the fixing screw sleeve group 2, any one of the arc-shaped clamps is slightly opened, and the Le Chatelier clamp 4 is placed into the first chamber, with one end of the Le Chatelier clamp 4 in contact with the limiting platform 5. Tighten the fixing screw sleeve group 2 so that the inner walls of the two arc-shaped clamps are in contact with the Le Chatelier clamp 4. The cement block inside the Le Chatelier clamp 4 is struck by the striking rod 7. The limiting platform 5 limits the Le Chatelier clamp 4. Under the striking of the striking rod 7, the cement block falls out of the Le Chatelier clamp 4, passes through the second chamber, and falls into the tray.
