Description

Technical Field

[0001] This invention relates to the field of concrete testing technology, specifically to an integrated device for concrete sample preparation and curing. Background Technology

[0002] Existing concrete sample preparation devices have several shortcomings in practical applications. Traditional equipment often has limited functionality and lacks an integrated process from concrete mixing and sample preparation to curing and preservation, resulting in cumbersome operation and low efficiency. Specifically, existing technologies have the following main drawbacks: First, the vibration process lacks precise control, leading to uneven vibration effects that can easily affect the quality of concrete samples. Furthermore, traditional vibration methods often rely on manual operation, which is labor-intensive and makes it difficult to ensure the consistency and stability of vibration. Second, the curing and transportation processes are greatly affected by environmental factors, especially the lack of a constant temperature and humidity environment, causing concrete samples to be prone to cracking and deformation during curing. In addition, traditional curing methods often require a large amount of space and have long curing cycles, affecting production efficiency and space utilization. Third, existing devices lack seamless integration between sample preparation, transportation, curing, and preservation, resulting in low automation and requiring significant manual intervention. This not only increases labor costs but also increases the risk of operational errors, affecting the efficiency and accuracy of concrete sample preparation. Finally, traditional equipment can easily damage concrete samples during demolding and extraction, affecting the integrity of the samples and the accuracy of subsequent test results.

The output shaft of the stepper motor 173 is coaxially and fixedly connected to one end of the first driving roller 171. The first driving roller 171 and the first driven roller 172 are connected by three hollow conveyor belts 174 arranged horizontally at equal intervals. In the working state, the first driving roller 171 and the first driven roller 172 drive the three hollow conveyor belts 174 to move synchronously, conveying the sample forming mold placed on the hollow conveyor belts 174 forward.

[0093] The frame supply unit 2 includes a frame storage rack 21, a pushing mechanism, and a coating mechanism. The frame storage rack 21 is located above and behind the first conveying mechanism 17, and has three vertically penetrating receiving cavities 211 on its inner side. Multiple sample forming molds are placed sequentially into each receiving cavity 211 through the top. After placement, the sample forming mold located at the bottom is ejected from the bottom of the receiving cavity 211 and falls onto the support platform of the main frame 8. The remaining sample forming molds are arranged in a regular order from top to bottom inside the receiving cavity 211.

[0094] The pushing mechanism is located below the rear side of the frame storage rack 21, pushing the sample forming molds onto the upper surface of the first conveying mechanism 17. The pushing mechanism includes a pushing frame 22, a linear cylinder 23, and L-shaped push plates 24. The pushing frame 22 is located below the frame storage rack 21, and its rear center is connected to the actuating end of the linear cylinder 23 via a connecting shaft. Three L-shaped push plates 24 are fixedly installed on the front side of the pushing frame 22, each corresponding to one of the three receiving cavities 211. During operation, the linear cylinder 23 drives the pushing frame 22 to move horizontally forward according to the instructions of the PLC controller. The three L-shaped push plates 24 push the three lowest sample forming molds forward onto the first conveying mechanism 17. The first conveying mechanism 17 then conveys the three sample forming molds forward to directly below the coating mechanism and stops.

[0095] The coating mechanism is located on the front side of the frame storage rack 21. The coating mechanism applies a release agent to the inner wall of the sample forming mold located on the first conveying mechanism 17. Specifically, the coating mechanism includes an oil storage box 25 and coating components. The oil storage box 25 is located on the front side of the frame storage rack 21, and its top is movably connected to the main frame 8 via a third electric cylinder 26. The third electric cylinder 26 drives the oil storage box 25 to rise or fall relative to the main frame 8. Three coating components are arranged below the oil storage box 25, and the positions of the three coating components and the three receiving cavities 211 correspond one-to-one. Two proximity switches 29 are symmetrically arranged on the front and rear sides of each coating component. All proximity switches 29 are connected to a PLC controller to control the sample forming mold to accurately reach and stop directly below the circular brush head 28 of the coating component.

[0096] The coating assembly includes a stepper motor 27 and a circular brush head 28 made of sponge. The stepper motor 27 is fixed to the bottom of the oil reservoir 25, and its output end is fixedly connected to the center of the circular brush head 28 via a vertical shaft. Each stepper motor 27 has an oil supply pipe on its adjacent side, which is arranged vertically. Its upper end is connected to the bottom of the oil reservoir 25, and its lower end is located above the circular brush head 28. Each oil supply pipe is equipped with a solenoid valve. The oil supply pipes inject the release agent inside the oil reservoir 25 into the circular brush head 28. The third electric cylinder 26 drives the oil reservoir 25 and the three circular brush heads 28 below it to lower. At the same time, the stepper motor 27 drives the corresponding circular brush head 28 to rotate, applying the release agent to the inner wall of the sample molding mold. After the release agent is applied, the third electric cylinder 26 drives the oil reservoir 25 to rise, disengaging it from the sample molding mold. At the same time, the circular brush head 28 stops rotating. Then, the first conveying mechanism 17 conveys the three sample forming molds forward to the area directly below the coating mechanism and then stops.

[0097] After the three sample molding molds stop directly below the discharge pipe 162, the output of the fourth servo motor 152 drives the control strip plate 151 to open the strip discharge port at the bottom of the receiving box 15. The concrete inside the receiving box 15 enters the three discharge funnels 161 of the discharge trough 16 through the strip discharge port, and enters the sample molding mold through the discharge pipe 162. Each discharge pipe 162 is equipped with a star valve, which controls the flow rate of the discharge pipe 162. Sufficient amount of concrete is injected into each sample molding mold.

In the working state, the two first lead screws 32 rotate synchronously and in the same direction, driving the two clamping plates 33 in the same set to move towards or in opposite directions.

[0101] The first conveying mechanism 17 transports the concrete-filled sample molding mold forward to the conveyor assembly inside the vibrating frame 31. Then, the first lead screw 32 drives the two clamping plates 33 in the same group to move towards each other, and the three sets of clamping plates 33 respectively limit the three sample molding molds. After that, the two vibration motors 313 start working, and the vibrating frame 31 drives the three sample molding molds above it to vibrate laterally and reciprocally.

[0102] The insert plate assembly and the smoothing mechanism are both located above the vibration frame 31 and are vertically connected to the main frame 8. The second conveying mechanism 18 is arranged adjacent to the front side of the vibration frame 31.

Its upper end is fixedly connected to the output shaft of the corresponding seventh servo motor 342 via a horizontally arranged connecting arm 351. The bottom of the square insert plate 35 has a single-sided cutting edge. During the vibration of the vibration frame 31 on the three sample molding molds, the square insert plates 35 reciprocate by inserting and removing the concrete near the four side walls inside the sample molding molds to eliminate air inside the concrete.

[0104] The smoothing mechanism includes an inverted U-shaped frame 36, a second lead screw 361, and a strip scraper 37. There are two inverted U-shaped frames 36, which are symmetrically arranged on the left and right sides above the vibrating frame 31.

Each transfer tray 44 has a rack 46 installed at the bottom, and the bottom of each rack 46 meshes with the corresponding gear 47. The stepper motor 48 drives all transfer trays 44 to move synchronously and linearly relative to the swing arm bracket 43 through the gears 47 and racks 46.

[0113] During operation, the first electric cylinder 41 drives the swing arm bracket 43 to descend to a set height, and the first servo motor 42 drives the swing arm bracket 43 to rotate around its axis to the front of the limiting bracket and approach the front end of the limiting bracket. The transfer tray 44 is positioned below the corresponding limiting bracket. The first electric cylinder 41 drives the swing arm bracket 43 to rise, and the transfer tray 44 is positioned between the two strip trays 192 with their upper surfaces at the same height. After the sample forming mold reaches the inner side of the limiting bracket, the first electric cylinder 41 continues to drive the swing arm bracket 43 to rise. After the transfer tray 44 raises the sample forming mold to the set height, the first servo motor 42 drives the swing arm bracket 43 to rotate 90° clockwise, reaching the outer right side of the curing chamber 51.

[0114] The molding and curing unit 5 includes a curing chamber 51, a temperature and humidity generator 52, and four curing racks 53. The curing chamber 51 has a cubic structure.
