Description

Technical Field

[0001] This invention relates to the field of sample preparation technology for cement strength testing, and more specifically, to a vibratory cement mortar specimen molding and compaction device. Background Technology

[0002] Cement mortar specimens are made from cement, Chinese ISO standard sand, and water, mixed, molded, and cured according to strict mass ratios and standard methods to form a specific size (generally a prism of 40mm x 40mm x 160mm). "Gel" refers to the cement slurry, which acts as a binder after hardening, and "sand" refers to Chinese ISO standard sand. "Cement mortar" is a mixture of cement binder and standard sand. It is not used for actual building components but rather as a "standardized test sample" or "measurement" of cement materials. Its sole purpose is to scientifically and accurately determine the mechanical strength properties of cement, primarily flexural and compressive strength, in a laboratory environment. The key to cement mortar strength testing lies in preparing standard specimens with uniform density and a compact internal structure. The molding quality of the specimens directly determines the accuracy and reliability of the strength test results, and has a decisive impact on the quality control and grading of cement products. Therefore, the preparation and molding of cement mortar specimens must involve vibration compaction to eliminate air bubbles, achieve high density, and ensure uniform mortar distribution, thus producing specimens that meet the standards.

[0003] The vibratory compaction table is the most commonly used standard equipment for compacting cement mortar. Its principle is to use a motor to drive a cam mechanism to make the table surface jump vertically at a fixed height and frequency, and rely on the impact force of falling to compact the cement mortar in the mold. However, the vibratory compaction table generates huge impact force and noise when it is working. In order to maintain its own stability and ensure the vibration effect, it must be firmly installed on a concrete foundation that weighs dozens of times more than itself. This installation method not only permanently occupies a huge amount of laboratory space, but also the foundation is complicated to construct, costly, and fixed in position, which greatly limits the flexible deployment of equipment and the layout planning of the laboratory. It poses a serious constraint on laboratories with limited space. At the same time, the core components of the vibratory compaction table, such as the motor, bearings and eccentric blocks, are under harsh conditions of high load and high impact for a long time, and wear out very quickly, which can easily lead to malfunctions such as amplitude inaccuracy, increased noise, and vibration direction deviation.

[0004] In the process of preparing cement mortar specimens, it is necessary to fill and compact the material twice. The first filling involves filling the mold with mortar to about half its height, and then compacting it to allow the mortar to flow under gravity and fully fill the bottom and four corners of the mold, providing a good foundation for the second filling. Then, the material is filled and compacted a second time to complete the overall molding. After each filling, the surface of the accumulated cement mortar must be initially scraped and then compacted. Both filling and scraping need to be done manually, which is a tedious operation. Summary of the Invention

[0005] The purpose of this invention is to provide a vibratory compaction device for cement mortar specimen molding to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides a vibratory compaction device for molding cement mortar specimens, comprising: A vibration table, with a worktable provided behind it; A test mold is placed on the vibration table, which can generate an excitation force to synchronously transmit to the test mold so that it vibrates at high frequency. A loading and leveling mechanism is provided on the workbench and extends above the vibrating table. The loading and leveling mechanism is used to automatically fill the mold with mortar in batches and then scrape the mortar flat to make the surface of the newly filled mortar tend to be flat. The vibratory compaction mechanism is installed on the loading and leveling mechanism. The vibratory compaction mechanism can vibrate the mortar twice in succession to fully reduce the internal voids of the mortar.

[0007] Furthermore, the loading and leveling mechanism includes: A linear motor is arranged on the worktable in the same direction as the test mold; A grooved component, which is mounted on the mover of the linear motor along the longitudinal direction of the mold; The main support member is movably assembled within the grooved member, and a groove is vertically formed on the main support member; Support arm, which is slidably mounted in a groove on the main support member and extends outward toward the mold side; A storage pot, which is mounted on the support arm and has an opening at the bottom; A material discharge channel is connected to the bottom of the storage pot, and the lower part of the material discharge channel is funnel-shaped. A first electric cylinder is mounted on the grooved part, and the output shaft of the first electric cylinder is connected to the lower end of the main support member. The second electric cylinder is mounted on the main support member, and the output shaft of the second electric cylinder is connected to the support arm. Support, the support being connected to the grooved member; A connecting component, which is installed on the outer wall of the material discharge channel and slidably connected to the support; An outer rod, which is connected to the connecting member; A pull-out insert, which is slidably inserted into the outer sleeve member; A bending pusher, wherein the bending pusher is connected to the tail end of the pull-out insert; A flow-stopping component is connected to the end of the bending and pushing component. The flow-stopping component is aligned with the material discharge channel, and the surface of the flow-stopping component is flush with the bottom surface of the material discharge channel.

[0008] Furthermore, the loading and leveling mechanism also includes: A leveling scraper is disposed on the bottom surface of the intercepting member.

[0009] Furthermore, the vibratory compaction mechanism includes: A fixed-point component, which is fixedly installed on the inner wall of the material discharge channel; A vibrating rod is inserted into the material discharge channel through the side wall of the material discharge channel. The vibrating rod is connected to the fixed point component, and the head of the vibrating rod is centered and vertically located in the material discharge channel.

[0010] Furthermore, the vibratory compaction mechanism also includes: Several sets of external support rods are axially and equally spaced connected to the head of the vibrating rod. The external support rods in several groups are arranged in a staggered manner.

[0011] Furthermore, the vibratory compaction mechanism also includes: A guide member, the guide member being mounted at the bottom of the bending pusher member; A push-pull rod that slides through the guide; The integrated crossbar is connected to the push-pull rod. The leveling scraper is composed of several toothed rods spliced ​​together. Several toothed rods arranged at intervals are slidably disposed on the bottom surface of the intercepting component, while the remaining toothed rods are fixed. The integrated crossbar is connected to several slidably disposed toothed rods. The push-pull rod and the guide are interference fit.

[0012] Furthermore, the vibration table includes: A support frame, on which a plurality of first springs are vertically arranged; The tabletop has corners on its bottom surface that are connected to several of the first springs, and the test mold is set on the tabletop. An inclined support plate is installed obliquely on the bottom surface of the platform; A vibration motor is mounted on the inclined support plate.

[0013] Furthermore, a vibration damping element is provided between the material discharge channel and the storage pot.

[0014] Furthermore, the support includes: An epitaxial carrier, wherein the epitaxial carrier is connected to the grooved member; A second spring is mounted on the extended carrier; A support member is mounted on the second spring, and the connecting member is slidably connected to the support member.

[0016] This vibratory cement mortar specimen molding and compaction device can automatically fill the mold with mortar in two stages through a loading and leveling mechanism. After each filling, it can immediately scrape the mortar horizontally to level the surface, making the surface of the mortar more flat. This achieves automatic loading and leveling, effectively improving the cumbersome manual operation steps and reducing manual intervention. This vibratory cement mortar specimen molding and compaction device uses a compaction mechanism to generate mechanical vibration during the filling and leveling process of the mortar into the mold. This vibration force is transmitted to the mortar, thus eliminating air bubbles and reducing voids, achieving the initial compaction of the cement mortar. After the mortar is filled into the mold, the compaction mechanism, in conjunction with the filling and leveling mechanism, can directly transmit physical vibration to the interior of the mortar, achieving a second compaction. The vibrating table promotes high-frequency vibration of the mold and the entire mortar assembly, further redistributing the aggregate and reducing voids. This vibratory cement mortar specimen molding and compaction device ensures thorough compaction of cement mortar, achieving uniform distribution and high density of mortar aggregate, and guaranteeing the preparation of specimens that meet standards. It also eliminates the problem of excessive impact force during vibration, effectively reducing noise and achieving a more continuous and stable compaction effect. Furthermore, it allows for diverse placement options, ensuring flexible deployment without occupying excessive laboratory space, thus providing more choices for laboratory layout planning.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] like Figure 1-13 As shown, a vibratory cement mortar specimen molding and compaction device includes: Vibration table 1, with a worktable 2 provided behind the vibration table 1; The test mold 3 is set on the vibration table 1, which can generate an excitation force to be synchronously transmitted to the test mold 3 to make it vibrate at high frequency. The material loading and leveling mechanism 4 is set on the workbench 2 and extends above the vibrating table 1. The material loading and leveling mechanism 4 is used to automatically fill the mortar into the test mold 3 in batches and then scrape the mortar flat so that the surface of the newly filled mortar tends to be flat. The vibratory compaction mechanism 5 is installed on the loading and leveling mechanism 4. The vibratory compaction mechanism 5 can vibrate the mortar twice to fully reduce the internal voids of the mortar. This vibratory cement mortar specimen molding and compaction device can automatically fill the mold 3 with mortar twice through the loading and leveling mechanism 4. After each filling, it can immediately scrape the mortar horizontally to level the mortar surface, making the mortar surface more flat. This realizes automatic loading and leveling, effectively improving the cumbersome manual operation steps and reducing manual intervention. This vibratory cement mortar specimen molding and compaction device, through the vibration compaction mechanism 5, generates mechanical vibration during the filling of the mortar into the mold 3 by the loading and leveling mechanism 4, and transmits the vibration force to the mortar. This physical vibration eliminates air bubbles in the cement mortar, thereby reducing voids and achieving the initial compaction of the cement mortar. Simultaneously, after the mortar is filled into the mold 3, the vibration compaction mechanism 5, in conjunction with the loading and leveling mechanism 4, can directly and fully transmit physical vibration into the interior of the mortar, thereby achieving secondary compaction of the mortar. The vibrating table 1 can cause the mold 3 and all the mortar as a whole to vibrate at a high frequency, thereby further promoting the redistribution of aggregates in the mortar and reducing voids. This vibratory cement mortar specimen molding and compaction device ensures thorough compaction of cement mortar, achieving uniform distribution and high density of mortar aggregate, and guaranteeing the preparation of specimens that meet standards. It also eliminates the problem of excessive impact force during vibration, effectively reducing noise and achieving a more continuous and stable compaction effect. Furthermore, it allows for diverse placement options, ensuring flexible deployment without occupying excessive laboratory space, thus providing more choices for laboratory layout planning.

[0022] Optionally, the loading and leveling mechanism 4 includes: Linear motor 41, which is arranged in the same direction as the test mold 3 on the worktable 2; The groove 42 is mounted on the mover of the linear motor 41 along the longitudinal direction of the mold 3. The mover is the component that moves back and forth on the linear motor 41. By driving the linear motor 41, the groove 42 is moved back and forth, and the position of the groove 42 relative to the mold 3 in the lateral direction is adjusted. The main support member 43 is movably assembled in the groove member 42, and a groove is vertically formed on the main support member 43. Support arm 44, which is slidably mounted in the groove on the main support member 43 and extends outward to the side of the test mold 3; Storage pot 45, which is mounted on the support arm 44 and has an opening at the bottom; The material discharge channel 46 is connected to the bottom of the storage pot 45, and the lower part of the material discharge channel 46 is funnel-shaped. The first electric cylinder 47 is disposed on the groove 42, and the output shaft of the first electric cylinder 47 is connected to the lower end of the main support member 43. By driving the first electric cylinder 47, the main support member 43 is pushed and pulled along the groove 42, thereby making the material discharge channel 46 closer to or further away from the test mold 3. The second electric cylinder 48 is mounted on the main support member 43, and the output shaft of the second electric cylinder 48 is connected to the support arm 44. By driving the second electric cylinder 48, the support arm 44 is pushed and pulled up and down along the groove on the main support member 43, so that the material discharge channel 46 can move closer to or further away from the test mold 3 in the vertical direction. Support 49, the support 49 being connected to the groove 42; Connector 491 is installed on the outer side wall of the material discharge channel 46 and slidably connected to the support 49; The outer rod 492 is connected to the connecting member 491; A pull-out insert 493 is slidably inserted into the outer sleeve member 492; A bending pusher 494 is connected to the tail of the pull-out insert 493; A flow-blocking component 495 is connected to the end of the bending and pushing component 494. The flow-blocking component 495 is aligned with the material discharge channel 46, and its surface is flush with the bottom surface of the material discharge channel 46. Under normal conditions, the pull-out insert 493 is fully inserted into the outer sleeve rod 492, at which point the flow-blocking component 495 completely seals the outlet of the material discharge channel 46. After the cement mortar is mixed, it is poured into the storage pot 45, and the cement mortar then falls along the storage pot 45 into the material discharge channel 46. Subsequently, the material discharge channel 46 is moved by the cooperation of the linear motor 41, the first electric cylinder 47, and the second electric cylinder 48, aligning it with the test mold 3 from above or inserting it into the test mold 3. Then, the bending and pushing component 494 is pulled backward, pulling the pull-out insert 493 out of the outer sleeve rod 492, and the flow-blocking component 495 disengages. The material discharge channel 46 is opened to allow cement mortar to fall into the mold 3. A linear motor 41 drives the material discharge channel 46 to move laterally, filling the mold 3 with mortar. A second electric cylinder 48 lifts the material discharge channel 46 to adjust its distance from the mold 3, ensuring that filling can be performed twice. In cement strength testing, to meet the requirements of a complete strength testing process, ensure the accuracy and reliability of experimental results, and improve experimental efficiency and economy, the mold 3 has three compartments, which can form three specimens at a time. Specifically, during material loading, after the current horizontal bar is filled, the first electric cylinder 47 is driven to push the material discharge channel 46 forward to the position of the next specimen, ensuring that the specific requirement of forming three specimens at a time is met.

[0023] Optionally, the loading and leveling mechanism 4 further includes: A leveling scraper 496 is disposed on the bottom surface of the interceptor 495. After loading is completed, the bending pusher 494 is pushed forward, and the interceptor 495 re-closes the outlet of the discharge channel 46. Then, the height of the discharge channel 46 is adjusted by the second electric cylinder 48 so that the leveling scraper 496 contacts the mortar and reaches a suitable position. Subsequently, the linear motor 41 drives the discharge channel 46 to move horizontally, thereby using the synchronously moving leveling scraper 496 to horizontally scrape the surface of the mortar, making the mortar surface tend to be flat, thus realizing automatic loading. The material is fed in a single piece, eliminating the need for multiple manual loading and leveling operations, effectively reducing tedious manual procedures and minimizing human intervention. A certain amount of friction is required between the pull-out insert 493 and the outer sleeve rod 492, or the pull-out insert 493 is fixed after the flow-stopping component 495 closes the outlet of the material discharge channel 46. This ensures the flow-stopping component 495 is securely closed, preventing unnecessary movement of the flow-stopping component 495 and leakage of internal mortar during mortar leveling. This is because the leveling scraper 496 is subjected to force that indirectly causes the pull-out insert 493 to retract, leading to unnecessary movement of the flow-stopping component 495.

[0024] Optionally, the vibratory compaction mechanism 5 includes: Fixed point component 51, which is fixedly installed on the inner wall of the material discharge channel 46; Vibrator 52 is an existing mechanized concrete compaction tool. The vibrator 52 is inserted into the material discharge channel 46 through the side wall of the channel. The vibrator 52 is connected to the fixing component 51. The head of the vibrator 52 is centered and vertically positioned within the material discharge channel 46. When the interceptor 495 is removed and material loading begins, the vibrator 52 is activated, causing it to vibrate within the material discharge channel 46. As the mortar creeps downwards, passing the vibrator 52, the mechanical vibration generated by the vibrator 52... The vibration can be quickly transmitted to the mortar, thereby efficiently breaking and eliminating air bubbles in the mortar through physical vibration, effectively reducing voids in the mortar aggregate, improving the density of the mortar, and ensuring that the mortar is filled into the mold 3 after being vibrated, thus ensuring the density of the mortar in the mold 3 and thus ensuring the preparation of specimens that meet the standards; at the same time, under the action of the vibration force of the vibrator 52, it can promote the downward flow of the mortar, ensuring its smooth and natural downward flow, avoiding the mortar from sticking and stagnating, which would require additional assistance to flow downward or cleaning.

[0025] Optionally, the vibratory compaction mechanism 5 further includes: Several sets of external support rods 53 are axially and equally spaced connected to the head of the vibrating rod 52; The external support rods 53 are arranged in a staggered manner. The external support rods 53 are driven by the vibrator 52 and also vibrate strongly. When the mortar comes into contact with the external support rods 53 during the downward flow, it can also be subjected to strong physical vibration. While not hindering the normal downward flow of the mortar, it indirectly expands the direct action area of ​​the vibrator 52, ensuring that all the mortar can be directly affected by the vibration force or be compacted near the vibration source, effectively improving the compaction effect and ensuring the comprehensiveness of the compaction effect.

[0026] Optionally, the vibratory compaction mechanism 5 further includes: Guide 54, the guide 54 being mounted on the bottom of the bending pusher 494; A push-pull rod 55, which slides through the guide 54; The integrated crossbar 56 is connected to the push-pull rod 55. The leveling scraper 496 is composed of several toothed rods, some of which are slidably arranged on the bottom surface of the interceptor 495, while the remaining toothed rods are fixed. The integrated crossbar 56 is connected to the several slidably arranged toothed rods. When the mortar is leveled, the vibrator 52 is stopped. After the mortar leveling operation is completed, the push-pull rod 55 is pulled back, and the integrated crossbar 56 pulls the several slidably arranged toothed rods backward, separating them from the fixed toothed rods. This divides the leveling scraper 496 into two comb-shaped parts. Then, the first electric cylinder 47 and the second electric cylinder 48 insert the leveling scraper 496 into the mortar, and then the vibration is started. The vibration of the moving rod 52 is transmitted to the leveling scraper 496 through the material feeding channel 46, connecting part 491, outer sleeve rod 492, pull-out insert 493, bending push part 494, and intercepting part 495, causing all the toothed rods to vibrate as well. The linear motor 41 drives the leveling scraper 496 to move back and forth laterally in the mortar, stirring it and causing the air bubbles inside the mortar to burst, float and be discharged, and the aggregate to be redistributed, increasing the density. This further strengthens the compaction effect, ensuring the uniform distribution and high density of the mortar aggregate to prepare specimens that meet the standards. After compaction, the push-pull rod 55 is pushed back to its original position, restoring the integrity of the leveling scraper 496 and ensuring that the leveling operation of the mortar can be performed smoothly. The push-pull rod 55 and the guide 54 are interference fit, meaning there is a certain amount of friction between them. A certain amount of force is required to pull the push-pull rod 55, ensuring that it can maintain its state after the leveling scraper 496 is pulled apart. This prevents the push-pull rod 55 from being pulled back to its original position due to resistance when the mortar is stirred, thus preventing normal compaction from being affected.

[0027] Optionally, the vibration stage 1 includes: A support frame 11, on which a plurality of first springs 12 are vertically arranged; The table 13 has corners on its bottom surface that are connected to a plurality of the first springs 12, and the test mold 3 is set on the table 13. Inclined support plate 14, which is obliquely installed on the bottom surface of the platform 13; The vibratory motor 15 is installed on the inclined support plate 14. After both loading and compaction are completed, the vibratory motor 15 is started, and the test mold 3 and the mortar inside it are vibrated at a high frequency through the platform 13. This once again promotes the redistribution of aggregate in the mortar, removes air bubbles, reduces voids, and achieves compaction, thus consolidating the compaction effect. Using the vibratory motor 15 and the vibratory rod 52 as the source of vibration force, the problem of huge impact force generated during vibration is completely solved while ensuring that standard test specimens can be prepared. It also effectively improves the noise during vibration, so as to achieve a more continuous and stable compaction effect, effectively reducing the failure rate. In addition, the device itself is small in size and does not need to be installed on a huge concrete foundation. The usage location can be arranged in a variety of ways to ensure flexible deployment, without occupying too much laboratory space, and supporting more choices in laboratory layout planning.

[0028] Optionally, a vibration damping element 6 is provided between the material discharge channel 46 and the storage pot 45. The vibration damping element 6 is made of a material with good elasticity. While connecting the material discharge channel 46 and the storage pot 45 and maintaining the sealing between the two, it forms a soft connection, which effectively reduces the efficiency of vibration transmission. This avoids excessive vibration force being transmitted through the storage pot 45 to the second electric cylinder 48 and other electric components and other parts, thus preventing resonance and ensuring the smooth and stable operation of the device.

[0029] Optionally, the support 49 includes: An extension carrier 497 is connected to the groove 42; The second spring 498 is mounted on the extension carrier 497; The support member 499 is mounted on the second spring 498, and the connecting member 491 is slidably connected to the support member 499. When the second electric cylinder 48 drives the storage pot 45 to move, the connecting member 491 slides synchronously on the support member 499, supporting the synchronous up and down movement of the material discharge channel 46. The second spring 498 maintains the support and fixation of the support member 499. At the same time, when the vibrator 52 is started to compact the mortar, the second spring 498 continuously absorbs vibration energy through elastic deformation, effectively reducing the vibration transmission efficiency, thereby reducing the amplitude of components such as the linear motor 41 and the first electric cylinder 47 and suppressing noise, thus further ensuring the smooth and stable operation of the device.

[0030] Optionally, the surface of the positioning component 51 is an arc-shaped convex surface, that is, the surface of the positioning component 51 presents a smooth convex surface. While positioning and fixing the vibrating rod 52, it ensures that all the mortar falling on the positioning component 51 can be shaken off under the action of vibration force, avoiding the accumulation of mortar residue on the positioning component 51, which would cause waste and cleaning burden.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
