Description

Technical Field

[0001] This application relates to the technical field of mortar testing equipment, and in particular to a mortar compaction device. Background Technology

[0002] Mortar compaction is a crucial step in cement mortar strength testing, used to prepare standard specimens. The process begins by filling a specially shaped mortar mold with the mixed cement mortar, then placing the mold on a compaction table. The compaction table uses vertical vibration at a specific frequency and amplitude to thoroughly compact the mortar within the mold, eliminating air bubbles and resulting in a specimen with a uniform structure that meets testing requirements. After compaction, excess mortar on the top of the mold must be scraped off to ensure a regular specimen shape before demolding, curing, and subsequent strength testing.

[0003] In existing mortar vibration compaction equipment, mechanical clamping is typically used to ensure the mortar mold remains stable and does not shift or jump during vibration. Specifically, a liftable cover plate (compaction plate) is installed above the compaction table. During operation, the mortar mold is placed on the compaction table, and then the height of the cover plate is adjusted manually or via a mechanism to press it down and press it tightly against the top of the mold. The weight and downward pressure of the cover plate then secure the mold to the table. Furthermore, to prevent slurry from overflowing and contaminating the table during secondary vibration, an additional material feeder is sometimes used, or operator skill is relied upon.

[0004] However, the existing technology that relies on cover plate compaction has obvious drawbacks: (1) Cumbersome and inconvenient operation: The height of the cover plate needs to be adjusted for compaction after each mold placement, which increases the operation steps and time; (2) Unstable fixing effect: The clamping force of the cover plate may be insufficient or improperly adjusted, which may cause the mold to slightly shift or loosen during violent vibration, affecting the compaction effect; (3) Redundant parts and easy to contaminate: The cover plate and its lifting mechanism and other components increase the complexity and number of parts on the table. At the same time, the slurry overflowing during the compaction process is very easy to flow into the cover plate, lifting mechanism, table and the gaps of these parts, causing serious contamination; (4) Difficult to clean and maintain: Slurry contamination and the presence of many parts make the cleaning, maintenance and upkeep of the equipment extremely cumbersome and time-consuming. Therefore, there is an urgent need for a mortar mold fixing solution that can simplify operation, improve fixing reliability, reduce redundant parts on the table and facilitate cleaning and maintenance. Utility Model Content

[0005] This application provides a mortar compaction device to solve the technical problems of existing mortar compaction table equipment, such as cumbersome and inconvenient operation, unstable fixing effect, redundant and easily contaminated parts, and difficult cleaning and maintenance.

[0006] This application provides a mortar compaction device, the device comprising: a support platform, a vibration component, an electromagnetic adsorption component, and a mortar container;

[0007] The support platform is connected to the vibration assembly, and the vibration assembly is used to drive the support platform to vibrate.

[0008] The electromagnetic adsorption assembly includes an electromagnet and a power supply device. The electromagnet is located inside the support platform, and the power supply device is electrically connected to the electromagnet. The power supply device is used to supply power to the electromagnet so that the electromagnet generates magnetic force.

[0009] The mortar container is made of ferromagnetic material so that when the mortar container is placed on the support platform, the magnetic force generated by the electromagnet attracts the mortar container, thereby fixing the mortar container to the support platform.

[0010] In one possible design, the electromagnetic adsorption assembly further includes a flexible protective sleeve that is fitted over the electromagnet and connected to the support platform.

[0011] In one possible design, the support platform has an internal mounting groove, and the electromagnet covered with the flexible protective sleeve is installed inside the groove, with the flexible protective sleeve abutting against the groove.

[0012] In one possible design, the electromagnet includes a magnetic core and a coil, with the coil wound around the outside of the magnetic core;

[0013] The flexible protective sleeve has a through hole, through which the coil's wire passes and is electrically connected to the power supply equipment.

[0014] In one possible design, the mortar container includes a feeder and a mortar mold, the feeder having a receiving space, and the mortar mold being fixed inside the receiving space;

[0015] The feeder has a ferromagnetic material so that when the feeder is placed on the support platform, the magnetic force generated by the electromagnet attracts the feeder, thereby fixing the feeder to the support platform.

[0016] In one possible design, a first magnetic element is provided within the receiving space, and the mortar mold is made of ferromagnetic material. The first magnetic element attracts the mortar mold to fix it inside the receiving space.

[0017] In one possible design, the mortar mold is provided with a second magnetic element, which is configured such that when the mortar mold is placed in the receiving space, the second magnetic element is located at the corresponding position of the first magnetic element, and there is an attractive force between the second magnetic element and the first magnetic element.

[0018] In one possible design, the support platform includes an upper platform and a lower support body, with the upper platform connected to the top of the lower support body;

[0019] The lower support body is provided with the mounting groove.

[0020] In one possible design, the lower support body is provided with a plurality of first bolt holes, and the upper platform is provided with a plurality of second bolt holes at the corresponding positions of the first bolt holes;

[0021] The device also includes a plurality of connecting bolts, which pass through corresponding first bolt holes and second bolt holes to connect the upper platform and the lower support.

[0022] In one possible design, the vibration assembly includes a vibration motor and an eccentric wheel;

[0023] The eccentric wheel is connected to the rotating shaft of the vibration motor, and the vibration motor is used to drive the eccentric wheel to rotate.

[0024] The housing of the vibration motor is connected to the support platform.

[0025] The mortar compaction device provided in this application has the following technical advantages:

[0026] Because this device uses an electromagnetic adsorption component (including an electromagnet and power supply equipment installed inside the support platform) to replace the traditional cover plate compaction mechanism, when the mortar container is placed on the surface of the support platform, the power supply equipment supplies power to the electromagnet to generate magnetic force, thereby directly and firmly adsorbing and fixing the magnetically conductive mortar container to the support platform for compaction. Therefore, redundant parts such as the traditional cover plate and lifting mechanism above the support platform can be completely eliminated, which significantly simplifies the equipment structure and reduces complexity. At the same time, since the fixing structure is integrated into the platform (i.e., the electromagnet is located inside the support platform), the potential contamination of platform parts and gaps after slurry leakage is greatly reduced, making cleaning and maintenance work simple and efficient. Thus, the entire device not only improves the reliability and convenience of fixing the mortar container (eliminating the cumbersome adjustment of the pressure plate), but also effectively solves the problems of easy contamination, difficult cleaning, and high maintenance costs caused by the complex structure of traditional equipment.

[0064] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0065] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0066] Because existing mortar compaction table equipment usually uses mechanical clamping to ensure that the mortar mold remains stable and does not shift or jump during vibration, the following problems arise: (1) Cumbersome and inconvenient operation: After each mold is placed, the height of the cover plate needs to be adjusted for clamping and fixing, which increases the operation steps and time; (2) Unstable fixing effect: The clamping force of the cover plate may be insufficient or improperly adjusted, which may cause the mold to shift slightly or loosen during violent vibration, affecting the compaction effect; (3) Redundant parts and easy to contaminate: The cover plate and its lifting mechanism and other components increase the complexity and number of parts above the table. At the same time, the slurry overflowing during the compaction process is very easy to flow into the cover plate, lifting mechanism, table and the gaps of these parts, causing serious contamination; (4) Difficult to clean and maintain: Slurry contamination and the presence of many parts make the cleaning, maintenance and upkeep of the equipment extremely cumbersome and time-consuming.

[0067] Therefore, the inventors of this application considered that if the mortar mold is not fixed by mechanical clamping, but instead by electromagnet adsorption to attach it to the surface of the vibrating table, and the electromagnet is built into the vibrating table, there will be no redundant parts on the working surface of the vibrating table, facilitating the cleaning of overflow slurry. Furthermore, since the electromagnet's magnetic force can be easily adjusted by adjusting the power, the fixing operation of the mortar mold can be simplified, ensuring its fixing effect. Therefore, based on the above ideas, the technical concept of this application is as follows: The device includes a support platform, a vibration component, an electromagnetic adsorption component, and a mortar container. The support platform is connected to the vibration component, which drives the support platform to vibrate. The electromagnetic adsorption component includes an electromagnet and a power supply device. The electromagnet is located inside the support platform, and the power supply device supplies power to the electromagnet to generate magnetic force. When the mortar container is placed on the support platform, the electromagnet's magnetic force attracts the mortar container, thereby fixing the mortar container to the support platform.

[0068] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0069] Example 1

[0070] Figure 1 Schematic diagram of the mortar compaction device provided in the embodiments of this application Figure 1 ,like Figure 1 As shown, the device includes: a support platform 100, a vibration assembly 200, an electromagnetic adsorption assembly 300, and a mortar container 400.

[0071] The support platform 100 is connected to the vibration assembly 200, which is used to drive the support platform 100 to vibrate.

[0072] The electromagnetic adsorption assembly 300 includes an electromagnet 310 and a power supply device 320. The electromagnet 310 is located inside the support platform 100. The power supply device 320 is electrically connected to the electromagnet 310 and is used to supply power to the electromagnet 310 so that the electromagnet 310 generates magnetic force.

[0073] The mortar container 400 is made of ferromagnetic material so that when the mortar container 400 is placed on the support platform 100, the magnetic force generated by the electromagnet 310 attracts the mortar container 400 and fixes the mortar container 400 on the support platform 100.

[0074] Figure 1 The direction of the middle arrow indicates the direction of magnetic adsorption. Specifically, when the mortar compaction device is started, the power supply device 320 of the electromagnetic adsorption component 300 (e.g., an adjustable DC power supply or a battery system) supplies power to the electromagnet 310 embedded inside the support platform 100 (the electromagnet 310 can be implemented, for example, a single columnar core coil group, a columnar iron core coil group arranged in a ring array, or a thin sheet electromagnetic film matching the contour of the support platform 100), so that the electromagnet 310 generates penetrating magnetic force when energized; since the bottom or side wall of the mortar container 400 is fused with a ferromagnetic material layer (e.g., using a stamped low-carbon steel plate insert, or sprayed with a magnetic metal composite coating), when the container is placed on the working surface of the support platform 100, the magnetic lines of force penetrate the non-magnetic support platform 100 surface material (the support platform 100 surface material can be, for example, stainless steel or engineering plastic) and adsorb the ferromagnetic material part in the mortar container 400, so that the container can remain stable and fixed even in a severe vibration environment.

[0075] In practice, adaptability can be improved through diversified design. For example, to adapt to mortar containers 400 of different sizes, the electromagnets 310 arranged in a ring array can be designed to be controlled independently in zones. For example, when a small mortar container 400 is placed, only the electromagnets 310 in the central area are activated, while when a large mortar container 400 is used, all electromagnets 310 are activated.

[0076] like Figure 1As shown, the vibration assembly 200 may include a vibration motor 210 and an eccentric wheel 220. The eccentric wheel 220 is connected to the rotating shaft of the vibration motor 210, and the vibration motor 210 drives the eccentric wheel 220 to rotate. The housing of the vibration motor 210 is connected to the support platform 100. Specifically, the vibration motor 210 in the vibration assembly 200 (e.g., a three-phase asynchronous motor or a brushless DC motor) drives the eccentric wheel 220 on its rotating shaft (e.g., a fan-shaped counterweight or a double cam structure with adjustable eccentricity). The periodic centrifugal force generated by the rotation of the eccentric wheel 220 is directly transmitted to the support platform 100 through the housing of the vibration motor 210, thereby causing the support platform 100 to generate vertical directional vibration. Furthermore, a phase marker sensor, such as a photoelectric encoder, can be installed on the eccentric wheel 220. When the eccentric wheel 220 is detected to be in the phase of maximum centrifugal force, the sand container 400 has the strongest upward throwing tendency. The control circuit instantly increases the current of the electromagnet 310 to counteract the separation force, thereby preventing the sand container 400 from detaching from the support platform 100.

[0077] Optionally, the vibration assembly 200 can be pneumatic. The pneumatic system of the vibration assembly 200 (for example, a double-acting cylinder with a three-position five-way directional valve) is rigidly connected to the support platform 100 through a piston rod. Compressed air drives the piston rod to reciprocate within the cylinder, thereby causing the support platform 100 to generate vertical impact vibration.

[0078] The technical advantages of this embodiment are as follows: Because the device uses an electromagnetic adsorption component 300, including an electromagnet 310 and a power supply device 320 installed inside the support platform 100, to replace the traditional cover plate compaction mechanism, when the mortar container 400 is placed on the surface of the support platform 100, the power supply device 320 supplies power to the electromagnet 310 to generate magnetic force, thereby directly and firmly adsorbing and fixing the magnetically conductive mortar container 400 onto the support platform 100 for compaction. Therefore, redundant components such as the traditional cover plate and lifting mechanism above the support platform 100 are completely eliminated, significantly simplifying the equipment structure and reducing complexity. Simultaneously, because the fixing structure is integrated into the platform surface (i.e., the electromagnet 310 is located inside the support platform 100), the potential contamination of platform components and gaps after slurry leakage is greatly reduced, making cleaning and maintenance simpler and more efficient. Thus, the entire device not only improves the reliability and convenience of fixing the mortar container 400 by eliminating cumbersome pressure plate adjustments, but also effectively solves the problems of easy contamination, difficult cleaning, and high maintenance costs caused by the complex structure of traditional equipment.

[0079] Example 2

[0080] Figure 2 Schematic diagram of the mortar compaction device provided in the embodiments of this application Figure 2 ,like Figure 2As shown, the electromagnetic adsorption assembly 300 also includes a flexible protective sleeve 330, which is fitted over the electromagnet 310. The flexible protective sleeve 330 is connected to the support platform 100. For example, a clamping element can be provided inside the support platform 100 to clamp the flexible protective sleeve 330 outside the electromagnet 310. Optionally, the support platform 100 has a mounting groove 110 inside, and the electromagnet 310 with the flexible protective sleeve 330 fitted is installed inside the groove of the mounting groove 110, with the flexible protective sleeve 330 abutting against the groove.

[0081] Specifically, when the mortar compaction device is working, the vibration component 200 drives the support platform 100 to vibrate vertically. During the vibration process, there is high-frequency micro-friction between the electromagnet 310 and the internal structure of the support platform 100. The electromagnetic adsorption component 300 forms an elastic isolation layer between the electromagnet 310 and the groove of the mounting groove 110 by covering the electromagnet 310 with a flexible protective sleeve 330 (e.g., a hollow cylindrical sleeve made of rubber, elastic silicone, or wear-resistant polyurethane) and bonding the outer wall of the protective sleeve to the side wall of the mounting groove 110 inside the support platform 100 (e.g., using high-temperature resistant epoxy). This reduces the wear of the electromagnet 310. In practice, the protective sleeve can be designed as a multi-layer composite structure, for example, the inner layer is a shock-absorbing sponge and the outer layer is tear-resistant rubber.

[0082] like Figure 2 As shown, the support platform 100 may include an upper platform 120 and a lower support body 130. The upper platform 120 is connected to the top of the lower support body 130, and the lower support body 130 is provided with a mounting groove 110. The lower support body 130 has multiple first bolt holes 131, and the upper platform 120 has multiple second bolt holes 121 at corresponding positions of the first bolt holes 131. The device also includes multiple connecting bolts 500, which pass through the corresponding first bolt holes 131 and second bolt holes 121 to connect the upper platform 120 and the lower support body 130. Figure 2 As shown, four first bolt holes 131 and four second bolt holes 121 can be provided, symmetrically arranged at the four corners of the support platform 100. Figure 2 The 600 connecting nut is used to fix the 500 connecting bolt.

[0083] like Figure 2 As shown, the lower support body 130 has connecting slots 700 on both sides. Figure 3 This is a schematic diagram of the connection slot and connection rod mating provided in an embodiment of this application. Figure 3 The diagram at the top center is a side view. Figure 3 The diagram at the bottom center is a top-down view. Figure 3 The direction of the middle arrow indicates the sliding direction of the connecting rod 800 within the U-shaped groove 710. For example... Figure 3As shown, to limit the support platform 100 to vibrate only vertically, the connecting slot 700 can have a U-shaped groove 710 through which the connecting rod 800 passes. The connecting rod 800 and the U-shaped groove 710 are slidably connected, allowing it to slide up and down within the U-shaped groove 710. Specifically, as... Figure 2 , Figure 3 As shown, since the connecting slot 700 connects to the support platform 100, when the support platform 100 vibrates, the connecting rod 800 slides downward relative to the U-shaped groove 710 when the support platform 100 moves upward, and slides upward relative to the U-shaped groove 710 when the support platform 100 moves downward. When the support platform 100 tends to shift horizontally, the connecting rod 800 presses against the side wall of the U-shaped groove 710, thus preventing the support platform 100 from moving laterally. The two ends of the connecting rod 800 can be connected to an external fixed base to fix its position.

[0084] Figure 4 This is a schematic diagram of the electromagnetic adsorption component structure provided in the embodiments of this application, such as... Figure 4 As shown, the electromagnet 310 includes a magnetic core 311 and a coil 312, with the coil 312 wound around the outside of the magnetic core 311; the flexible protective sleeve 330 has a through hole 331, through which the wire of the coil 312 passes and is electrically connected to the power supply device 320. Specifically, as... Figure 4 As shown, the magnetic core 311 can be T-shaped, and the coil 312 is wound around the thin end of the lower part of the T-shaped magnetic core 311 in several turns.

[0085] Alternatively, the opening of the through hole 331 can be designed as a flared, trumpet-shaped opening to prevent the bent portion of the wire passing through the through hole 331 from rubbing against the hole edge during vibration of the mortar compaction device. The wire can be designed to be suspended within the through hole 331 to further reduce friction between the wire and the flexible protective sleeve 330. Through the above design, the possibility of the coil 312 wire breaking under long-term high-frequency vibration can be reduced.

[0086] Figure 5 This is a schematic diagram of the material feeder 410 provided in an embodiment of this application. Figure 5 The image shows a cross-sectional view of the interior of the feeder 410. (See image for details.) Figure 5 As shown, the feeder 410 has a three-section structure. The two inner side plates 411 and the bottom plate of the feeder 410 form a receiving space 413, which has a total of three parallel receiving spaces 413. The bottom of the receiving space 413 can be designed to be slightly recessed to reduce mortar residue. Figure 5 As shown in the mid-section view, a first magnetic element 412 can be provided on the lower side of the inner plate 411 of the feeder 410. The feeder 410 is made of ferromagnetic material so that when the feeder 410 is placed on the support platform 100, the magnetic force generated by the electromagnet 310 attracts the feeder 410, thereby fixing the feeder 410 to the support platform 100.

[0087] Figure 6 Schematic diagram of the mortar container structure provided in the embodiments of this application Figure 1 ,like Figure 6 As shown, the mortar container 400 includes a feeder 410 and a mortar mold 420, which is fixed inside the receiving space 413. The mortar mold 420 is made of ferromagnetic material, which causes the first magnetic element 412 to attract the mortar mold 420, thus fixing the mortar mold 420 inside the receiving space 413.

[0088] Figure 7 Schematic diagram of the mortar container structure provided in the embodiments of this application Figure 2 , Figure 7 The direction of the middle arrow indicates the direction of the magnetic force. For example... Figure 7 As shown, the mortar mold 420 is provided with a second magnetic component 421. The second magnetic component 421 is configured such that when the mortar mold 420 is placed in the receiving space 413, the second magnetic component 421 is located at the corresponding position of the first magnetic component 412, and there is an attractive force between the second magnetic component 421 and the first magnetic component 412. By providing the second magnetic component 421 and configuring the first magnetic component 412 and the second magnetic component 421 to be attracted to each other, the firmness of the mortar mold 420 in the receiving space 413 can be further improved.

[0089] Finally, it should be noted that other embodiments of this utility model will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This utility model is intended to cover any variations, uses, or adaptations of this utility model that follow the general principles of this utility model and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
