Description

Technical Field

[0001] This application relates to the field of concrete standard curing test block production technology, and in particular to an automatic device for producing concrete standard curing test blocks. Background Technology

[0002] Concrete standard-curing test blocks serve as the core basis for evaluating key properties of concrete, such as compressive strength and durability. Their manufacturing quality directly affects the accuracy of structural safety assessments. In the field of building engineering, standard-curing test blocks must complete strength testing under 28 days of standard curing conditions; the data is crucial evidence for project acceptance and quality traceability.

[0003] In the existing technology, the production of standard curing concrete test blocks mainly relies on manual operation throughout the entire process: after on-site sampling, the concrete needs to be manually mixed to ensure homogeneity, then the concrete is poured into the test mold, manually vibrated and compacted using a vibrator, and finally the surface is smoothed and left to cure until demolding.

[0004] However, manual operation relies heavily on the operator's experience. Significant subjective differences exist in everything from controlling the mixing time and the uniformity of vibration intensity to the precision of the smoothing process. Especially in the vibration stage, it is difficult for humans to accurately control the vibration time and intensity, which can easily lead to insufficient vibration resulting in excessively large internal pores, or excessive vibration causing aggregate segregation. When smoothing, manual operation can easily cause deviations in surface flatness. All of these factors directly affect the quality of the test block molding. Utility Model Content

[0020] Example implementations will now be described more fully with reference to the accompanying drawings. However, example implementations can be implemented in many forms and should not be construed as limited to the examples set forth herein.

[0021] Conversely, these implementations are provided to make the embodiments of this application more comprehensive and complete, and to fully convey the concept of exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more implementations. In the following description, numerous specific details are provided to give a thorough understanding of the implementation of the embodiments of this application.

[0022] Concrete standard-curing test blocks are the core basis for evaluating the key performance of concrete, and their production quality affects the accuracy of structural safety assessments. In construction engineering, standard-curing test blocks require 28 days of standard curing before strength testing, and the data serves as important evidence for project acceptance and quality traceability. With the development of the construction industry, the requirements for the efficiency, accuracy, and consistency of test block production have increased, and traditional manual production methods are difficult to meet these needs.

[0023] In the prior art, the entire process of manufacturing standard cured concrete test blocks relies on manual work, including manual mixing, mold loading, vibrating and troweling after on-site sampling, which is highly dependent on the experience of operators, and there are subjective operation differences in each link. It is difficult to accurately control the time and force during vibrating, which easily leads to insufficient or excessive vibrating; the surface flatness is prone to deviation during troweling, which affects the molding quality of the test blocks. There are three main problems in the current technology: first, large manual operation errors lead to uneven compactness and poor surface flatness of test blocks, high strength discreteness of test blocks in the same batch, and low reliability of detection results; second, the manufacturing efficiency is low, which is difficult to meet the requirements of large-scale projects; third, high labor cost, harsh working environment, and the lack of special equipment for full-process automatic manufacturing restrict the upgrade of test block preparation technology. Therefore, it is of great significance to develop a fully automatic manufacturing device for standard cured concrete test blocks.

[0024] An embodiment of the present application provides an automatic manufacturing device for standard cured concrete test blocks, with reference to Figure 1 as shown in the figure, the frame 1 serves as an overall support structure, and a mixing module 2, a mold loading and vibrating module 3, a troweling module 4, a demolding module 5 and a conveying module 6 are sequentially integrated along the length direction of the frame.

[0025] The mixing module 2 is fixed at the front end of the top of the frame 1, and its mixing drum 21 adopts a barrel-shaped container structure, and the open top design facilitates concrete feeding; a mixing motor 22 is installed at a position of the frame 1 close to the bottom of the mixing drum 21, and its output shaft extends into the drum to drive the mixing blade to rotate, so as to realize homogenization treatment of concrete.

[0026] The mold loading and vibrating module 3 is located behind the mixing module 2, and includes a test mold conveying track 31, a positioning mechanism 32 and a vibrator 33. The test mold conveying track 31 is a synchronous belt transmission mechanism extending horizontally along the top of the frame 1, the positioning mechanism 32 is arranged across the track to fix the test mold through clamping blocks, and the vibrator 33 adopts a high-frequency electromagnetic device suspended directly above the positioning mechanism 32.

[0027] The troweling module 4 is closely adjacent to the output side of the mold loading and vibrating module 3, and is composed of a gantry-type transverse moving frame 41 and a vertically installed scraper 42, and the lower edge of the scraper 42 contacts the upper surface of the test mold to realize the troweling function.

[0028] The demolding module 5 is arranged at the rear end of the top of the frame 1, and includes a vertically installed electric / hydraulic lifting mechanism 51 and an ejection rod 52 fixed on the top thereof. The conveying module 6 is located below each module, a conveying belt 61 is a belt conveyor horizontally laid at the bottom of the frame 1 and extends from below the demolding module 5 to a storage area, and guide plates 62 are fixed on both sides of the conveying belt 61 to ensure transportation stability. The control system 7 is integrated on the side of the frame 1 in the form of a programmable logic controller, and is connected to sensors and actuating elements of each module through cables to realize linkage control.

[0029] After starting the equipment, the operator pours the concrete sample into the mixing tank 21. The control system 7 controls the mixing motor 22 to drive the blades to rotate and complete the homogenization mixing. After mixing, the valve at the bottom of the mixing tank 21 is opened, and the concrete flows into the mold on the mold conveying track 31 through the discharge port. The mold moves with the track to the positioning mechanism 32 for fixing, and the vibrator 33 is started to perform high-frequency vibration to eliminate air bubbles inside the concrete. After vibration, the mold is conveyed to the bottom of the smoothing module 4, and the horizontal moving frame 41 drives the scraper 42 to move horizontally to scrape away excess concrete and achieve a smooth surface. Then the mold moves to the demolding module 5, and the lifting mechanism 51 drives the ejector rod 52 to rise and eject the hardened test block. The finished test block is transported to the storage area by the conveyor belt 61, and the empty test mold is circulated back to the starting end of the mold vibration module 3 via the conveyor belt 61. Each module achieves real-time monitoring of its operating status and programmed linkage through the sensor network of the control system 7, solving the technical problems of low efficiency, large quality fluctuations, and significant human error in traditional manual test block production.

[0030] The device in this embodiment eliminates concrete inhomogeneity through mechanical mixing via homogenization, and then achieves concrete compaction through electromagnetic vibration using high-frequency vibration. The fully automated process reduces manual intervention and lowers labor costs. Furthermore, homogenization mixing and high-frequency vibration ensure consistent test block quality, improving the accuracy of test results. The device's operation is monitored in real-time by a control system, ensuring precise linkage between each step. This achieves a high degree of automation in test block production, eliminating human error and improving the stability and efficiency of test block quality. It is suitable for large-scale standardized production of concrete test blocks.

[0031] In some embodiments of this application, the mixing tank 21 of the mixing module 2 is fixed at the top center of the frame 1. Its open top design facilitates material feeding, and a discharge port is located on the bottom side away from the mixing motor 22, directly opposite the mold conveying track 31 of the mold-loading and vibration module 3. The mixing motor 22 is installed on the frame 1 near the bottom of the mixing tank 21, with its output shaft extending into the tank and connecting to the mixing blades for rotational drive. The connection between the mixing tank 21 and the mixing motor 22 ensures that concrete flows directly from the discharge port of the mixing tank 21 into the mold, forming a continuous production flow.

[0032] Specifically, after the concrete is mixed in the mixing tank 21, the opening and closing of the discharge port is controlled by the bottom valve, and the concrete flows into the test mold on the test mold conveying track 31 under the action of gravity. The design of the mixing module 2 solves the problems of low efficiency and easy spillage of concrete in traditional manual mold filling. Through the precise docking of the discharge port and the test mold conveying track 31, the automation and continuity of concrete mold filling are realized.

[0033] As the first step in concrete processing, the mixing module 2 achieves homogenization of the concrete through the coordinated work of the mixing tank 21 and the mixing motor 22, and automatically loads the concrete into molds by connecting the discharge port to the mold conveying track 31. Automated mold loading reduces manual intervention, lowers the risk of concrete spillage, and ensures consistent mixing results through precise volume and speed parameters. Simultaneously, it solves the efficiency and quality problems of traditional manual mixing and mold loading, and programmed control improves the continuity and controllability of the production process, enhancing the automation level and production efficiency of the entire test block production process.

[0034] In some embodiments of this application, the volume of the mixing tank 21 is set to 30-100L, based on the standard volume requirements for concrete test block preparation, ensuring that the amount of material mixed in a single batch meets the mold filling requirements. The speed range of the mixing motor 22 is set to 10-50 r / min, and the speed can be adjusted from low to medium speed to adapt to the mixing needs of concrete with different viscosities. The valve at the discharge port at the bottom of the mixing tank 21 is directly controlled by the control system 7 to achieve precise timing control of the discharge process.

[0035] Specifically, under the timing control of control system 7, the valve opens after mixing is completed, and concrete flows into the test mold through the discharge port; during mixing, the valve remains closed to prevent concrete leakage. The valve control program is based on the principle of automatic control, using sensors to monitor the mixing completion status and trigger valve opening and closing commands. Programmed control can improve the controllability and reliability of the discharge process.

[0036] In this embodiment, the mixing module 2 achieves automated homogenization and precise molding of concrete through the synergistic effect of volume, rotation speed and valve control.

[0037] In some embodiments of this application, the mold conveying track 31 of the mold-loading and vibrating module 3 can adopt a synchronous belt drive mechanism, extending horizontally along the top of the frame 1 and located between the mixing module 2 and the positioning mechanism 32. The positioning mechanism 32 is positioned above the mold conveying track 31, and the mold is precisely fixed by a clamping block driven by a cylinder or electric push rod. The vibrator 33 is fixed on the frame 1, located directly above the positioning mechanism 32, and its output end extends into the positioning mechanism 32 to achieve high-frequency vibration function.

[0038] The test mold conveying track 31 transports the test mold from the discharge port of the mixing module 2 to the positioning mechanism 32 for fixation, ensuring the stability of the test mold position during vibration. After concrete is poured into the test mold, the vibrator 33 starts high-frequency vibration. The high-frequency electromagnetic vibration of the vibrator 33 eliminates air bubbles inside the concrete based on the principle of vibration wave propagation, and high-frequency vibration can also improve the density of concrete and the accuracy of test block strength testing.

[0039] In some embodiments of this application, the vibration frequency range of the vibrator 33 is set to 50-200Hz to ensure that concrete of different viscosities can be effectively compacted. The positioning accuracy of the mold conveying track 31 is set to ±2mm, and the precise conveying and fixing of the mold is achieved through the coordinated action of synchronous belt drive and positioning mechanism 32.

[0040] In some embodiments of this application, the transverse moving frame 41 of the smoothing module 4 adopts a gantry-type support structure, spanning the top of the frame 1 and located between the mold loading and vibration module 3 and the demolding module 5. The scraper 42 is vertically mounted on the transverse moving frame 41 via a bracket, and its lower edge contacts the upper surface of the mold to achieve the smoothing function. The transverse moving frame 41 is driven to move horizontally, and the moving speed is adjustable from 0.5 to 1 m / s.

[0041] The gantry structure of the transverse moving frame 41 has good mechanical strength and stability, ensuring the stability of the scraper 42 during movement. The relative movement of the scraper 42 with the surface of the mold enables the removal of concrete and surface smoothing. Furthermore, the range of moving speeds ensures that the smoothing process is both efficient and guarantees surface quality.

[0042] In some embodiments of this application, the scraper 42 is made of wear-resistant rubber, and its length matches the width of the mold, ensuring complete coverage of the mold surface during the smoothing process. The wear-resistant rubber material possesses excellent wear resistance and flexibility, ensuring effective removal of excess concrete without damaging the mold surface during smoothing. This allows the scraper 42 to maintain a stable smoothing effect over long-term use, improving its service life and the consistency of its smoothing effect.

[0043] In some embodiments of this application, the lifting mechanism 51 of the demolding module 5 employs a vertically mounted electric or hydraulic cylinder, fixed to the frame 1 to achieve vertical lifting movement. The ejector rod 52 is directly fixed to the top movable end of the lifting mechanism 51. Its top is a planar structure and has undergone hardening treatment to ensure that the ejection force can be uniformly transmitted during the ejection process, avoiding damage caused by local stress concentration on the surface of the test block. The hardening treatment is based on the principle of material surface strengthening, improving the wear resistance and compressive strength of the top of the ejector rod 52.

[0044] Specifically, after curing, the molded specimen moves along the mold conveyor track 31 to the demolding module 5. The lifting mechanism 51 drives the ejector rod 52 to rise at a speed of 3-10 mm / s, ejecting the hardened specimen from the mold. The range of lifting speeds ensures that the demolding process is both efficient and safe.

[0045] In this embodiment, the demolding module 5 achieves automatic demolding of concrete test blocks through the coordinated action of the lifting mechanism 51 and the ejector rod 52, realizing a safe and stable demolding effect and improving the reliability and consistency of demolding quality.

[0046] In some embodiments of this application, the conveyor belt 61 has an adjustable conveying speed of 0.1-0.5 m / s and a width of 200-400 mm to ensure stable support of the test block and empty mold during conveying. The control system 7 uses a programmable logic controller, integrates an external touch screen and multiple sensors, and the sensors are distributed along the guide plate 62 and set on each module to realize real-time monitoring and linkage control of the operating status.

[0047] The conveying speed range ensures efficient transport without causing displacement of the test block or empty mold due to excessive speed. The width setting is based on the principle of matching the dimensions of the test block and the empty mold to ensure stable load-bearing capacity.

[0048] Furthermore, the sensor network of control system 7 is based on the principle of automated monitoring and control, realizing real-time feedback and programmed linkage of operating status. Through the coordinated action of conveyor belt 61 and sensor network, conveyor module 6 and control system 7 achieve automatic conveying of test blocks and empty test molds, as well as full-process linkage control.

[0049] In summary, the automatic concrete standard curing test block production device provided in this application allows the operator to pour concrete samples taken from the pouring site into the mixing tank of the mixing module. The operator then sets parameters such as mixing time and vibration frequency via the touchscreen of the control system. After starting the equipment: the mixing motor starts, driving the mixing blades to rotate and mix for the set time to ensure the sampled concrete has a uniform texture. After mixing, the valve at the bottom of the mixing tank opens, and the concrete flows into the test mold of the molding and vibration module. The test mold is then conveyed to the positioning mechanism via a conveying track and fixed. The vibrator starts and vibrates at high frequency for the preset time before stopping. The moving frame of the smoothing module moves the scraper laterally to remove excess concrete from the surface of the test mold. The test mold containing concrete is conveyed to the curing area via the conveying module. After curing, it returns to the demolding module, where the ejector rod rises to eject the test block. The test block is then conveyed to the storage area by the conveying module, while the empty test mold is re-conveyed to the molding and vibration module for reuse.

[0050] It can be known from the above embodiments that the device realizes full-process automation of concrete test block preparation through the cooperative work of the stirring module, mold loading and vibrating module, leveling module, demolding module and conveying module. Operators only need to complete concrete feeding and equipment starting operations, and the subsequent processes of stirring, mold loading, vibrating, leveling, demolding and conveying are all automatically completed by the equipment. The control system realizes linkage control of each module through the sensor network, ensuring the continuity and controllability of the whole process. The automated whole process of the solution reduces manual intervention and labor costs; homogeneous stirring and high-frequency vibrating improve the quality consistency of test blocks; continuous operation of each module improves production efficiency; the sensor network realizes real-time monitoring of operating conditions, ensuring production safety and stable quality. The device is suitable for large-scale standardized production of concrete test blocks, and can be widely used in concrete quality inspection scenarios in construction, bridges, tunnels and other engineering fields.
