Description

Technical Field

[0001] This application relates to the field of cement mortar testing technology, specifically a cement mortar flowability measuring device. Background Technology

[0002] Cement mortar is a building material made by mixing cement, standard sand, and water in a certain proportion. It is widely used in the construction and engineering fields to test the physical and mechanical properties of cement and in actual engineering operations such as masonry, plastering, and repair. In order to facilitate the evaluation of the workability of cement mortar, it is necessary to measure the fluidity of cement mortar. Generally, mortar with high fluidity is easy to mix, pour, and shape, which can reduce the difficulty of construction and improve work efficiency. On the other hand, cement mortar with insufficient fluidity may cause the mortar to be difficult to vibrate and compact, resulting in defects such as honeycomb and voids.

[0003] For example, the patent with authorization announcement number CN214539106U discloses a cement mortar flowability tester, which includes a support platform and a tester body. The tester body is installed on the support platform and includes a platform, a truncated cone mold and a second drive component. The truncated cone mold can maintain vertical upward movement during the lifting process, reducing the possibility of shaking when the truncated cone mold is lifted and improving the accuracy of cement mortar flowability test results.

[0004] Although the above-mentioned device achieves the determination of the flowability of cement mortar, cement mortar is a fluid, and the flowability measurement process is highly random. At least two flowability tests should be performed on the same group of cement mortar and the average value should be taken to obtain more accurate test results. However, after a flowability test, the cement mortar is in a spread-out state. Before the next test, the cement mortar should be gathered together. If manual operation is required during the gathering process, it will undoubtedly greatly reduce the efficiency of cement mortar measurement. Therefore, it is necessary to provide a cement mortar flowability measuring device to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a cement mortar flowability testing device, which solves the problem that the cement mortar flowability testing device cannot automatically gather cement mortar.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figures 1-2 As shown, this application provides a cement mortar flowability measuring device, including a base plate 1, a support seat 2 fixedly installed at the bottom of the base plate 1, the support seat 2 mainly provides stable support for the base plate 1, support columns 3 fixedly installed at the four corners of the top of the base plate 1, springs 31 fixedly installed at the top of the support columns 3, and a jumping table 4 fixedly installed at the bottom of the springs 31. The jumping table 4 mainly provides a platform for measuring the flowability of cement mortar. When the jumping table 4 is under pressure, the spring 31 is compressed, and conversely, when the jumping table 4 is lifted, the spring 31 is stretched.

[0025] A motor 5 is fixedly mounted on the top of the base plate 1. A cam 51 is fixedly mounted on the output end of the motor 5. When the motor 5 starts, its output end drives the cam 51 to rotate. At the same time, a contact 52 is fixedly mounted on the bottom of the jumping table 4. Initially, the contact 52 and the cam 51 are not in contact. When the motor 5 starts, the cam 51 will rotate. During the rotation of the cam 51, its protruding end is adapted to contact the contact 52 and exert a squeezing effect on it. When the end of the cam 51 furthest from the axis of the output end of the motor 5 contacts the contact 52... When the contact 52 contacts, the jumping table 4 is raised to the maximum extent. When the cam 51 moves away from the contact 52, the jumping table 4 returns to its initial state. During this process, the spring 31 adapts to the up and down movement of the jumping table 4. After the external force is released, the jumping table 4 returns to its initial state due to the elastic force. Through the coordinated use of the motor 5, cam 51, contact 52 and spring 31, the up and down movement of the jumping table 4 can be realized, producing a vibration effect. In this embodiment, the bottom of the contact 52 is arc-shaped, which facilitates the contact and separation of the cam 51.

[0026] Continue to refer to Figure 1 Four sets of outer plates 41 are fixedly installed on the top of the jumping table 4. The four sets of outer plates 41 are close to each other and form a first chamber. At the same time, four sets of inner plates 6 are set on the top of the jumping table 4. The inner plates 6 are located in the first chamber. The inner plates 6 are close to each other to form a cube, and a working chamber is formed between them. The cement mortar to be tested is placed in the working chamber for flowability measurement. At least two sets of sliding rods 7 are slidably installed on the inner plates 6. One end of the sliding rod 7 passes through the inner plate 6 and is fixedly connected to the outer plates 41. When subjected to external force, the inner plate 6 is suitable for sliding on the sliding rod 7. The sliding rod 7 provides support for the inner plate 6.

[0027] When measuring the flowability of cement mortar, simply place the cement mortar in the working chamber, then start the motor 5. The motor 5 drives the cam 51 to rotate. During the rotation, the cam 51 periodically contacts and separates from the bottom of the contact piece 52, causing the jumping table 4 to vibrate. The vibration of the jumping table 4 causes the cement mortar to vibrate. During the vibration, the cement mortar is shaken and flows freely. After a certain number of vibrations, the flow of the cement mortar can be observed, and its state after shaking can be measured to determine the flowability of the cement mortar.

[0028] After the first test, the loosened cement mortar needs to be gathered again for a second test. This ensures that the flowability test results of the cement mortar are more accurate. Figure 1 , Figures 3-4As shown, a limiting groove is provided at the bottom of the inner panel 6, and a push block 81 is placed in the limiting groove. The push block 81 is adapted to the limiting groove. A cylinder 8 is fixedly installed on the side of the outer panel 41 that is close to each other. The output end of the cylinder 8 is fixedly connected to the push block 81. When the cylinder 8 is started, its output end drives the push block 81 to move forward.

[0029] Initially, push block 81 is located in the limiting groove, and it fills the groove. During flowability testing, the cement mortar will not flow out of the limiting groove. When it is necessary to gather the dispersed cement mortar, simply activate cylinder 8 to move push block 81 forward. Push block 81 contacts the cement mortar and pushes it. It should be noted that to avoid collisions between adjacent push blocks 81, cylinder 8 is activated alternately when controlling cylinder 8. Figure 1 Taking the perspective as an example, in this application, there are a total of four sets of cylinders 8. For ease of explanation, the corresponding cylinders 8 are listed as the same batch, and the four sets of cylinders 8 are divided into the first batch and the second batch. During the start-up process, the first batch of cylinders 8 starts first, while the second batch of cylinders 8 is in a stationary state. At this time, the first batch of cylinders 8 starts, which drives the corresponding push blocks 81 to move closer to each other, thus bringing the cement mortar together. After the output end of the first batch of cylinders 8 extends to the limit position, the push blocks 81 do not move closer to each other, and the cement mortar will be gathered between the push blocks 81. Then the first batch of cylinders 8 closes. After the first batch of cylinders 8 closes, the second batch of cylinders 8 starts. The two batches of cylinders 8 open and close alternately, thus bringing the cement mortar together.

[0030] After the cement mortar testing is completed, it needs to be removed from the working chamber. However, the space in the working chamber is limited, making it inconvenient to remove the cement mortar. Figure 1 As shown, at least two sets of vertical plates 9 are also fixedly installed in the first chamber. The two ends of the vertical plates 9 are fixedly connected to the outer plate 41, the bottom of the vertical plates 9 is fixedly connected to the top of the jumping table 4, and the other end of the cylinder 8 is fixedly connected to the vertical plates 9 to further increase the stability of the cylinder 8.

[0031] At least two sets of positioning holes 11 are provided on one side of the vertical plate 9. The positioning holes 11 are arranged in parallel. At the same time, an insertion hole is provided on one side of the inner circumference plate 6. The diameter of the insertion hole is the same as the diameter of the positioning hole 11. A positioning pin 10 is inserted into the insertion hole. The other end of the positioning pin 10 is inserted into the positioning hole 11. During the operation, in order to ensure the stability of the inner circumference plate 6, the positioning pin 10 is inserted into the positioning hole 11 on the side away from the outer circumference plate 41.

[0032] After the test is completed, in order to facilitate the removal of cement mortar from the working chamber, it is necessary to expand the space of the working chamber. For this purpose, the inner cladding plate 6 needs to be moved to the side away from each other. At this time, the positioning pin 10 needs to be pulled out from the positioning hole 11, and then the inner cladding plate 6 is slid to the side away from each other. After the sliding is completed, the positioning pin 10 can be inserted into the positioning hole 11 on the side close to the outer cladding plate 41 to limit the inner cladding plate 6. After the inner cladding plate 6 moves in sequence, the space of the working chamber becomes larger, which facilitates the removal of cement mortar from the working chamber.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
