Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete strength testing, and in particular to a pressure testing device for concrete strength testing. Background Technology
[0002] In the traditional process of concrete strength testing, a pressure testing machine is usually used to test the compressive strength of concrete specimens. However, existing equipment generally suffers from problems such as cumbersome operation, inaccurate specimen positioning, and difficulty in cleaning up waste after testing.
[0003] Conventional testing equipment requires manual placement of the specimen to the center of the pressure table, which is not only labor-intensive but also prone to affecting testing accuracy due to positioning deviations. At the same time, the concrete residue after crushing needs to be cleaned manually, which is inefficient and can easily cause material to accumulate inside the equipment.
[0004] To address the aforementioned issues, this patent proposes a concrete strength testing device that enables precise specimen positioning, automatic waste collection, and convenient operation, thereby improving testing efficiency, reducing labor intensity, and ensuring the accuracy of test data. Utility Model Content
[0005] The main purpose of this invention is to propose a pressure testing device for concrete strength testing, which aims to solve the problem of high labor intensity caused by the traditional concrete strength testing device relying on manual placement of concrete specimens to the center of the pressure table.
[0006] To address the aforementioned problems, this utility model proposes a pressure testing device for concrete strength testing, comprising a testing cabinet. The lower inner wall of the testing cabinet is inclined with a left-lower, right-higher profile. A hydraulic press is located at the center of the upper end of the testing cabinet. A hydraulic rod is installed inside the lower end of the hydraulic press, with its lower end penetrating inside the testing cabinet. An upper pressure plate is connected to the lower end of the hydraulic rod. A lower pressure column is located directly below the upper pressure plate and is connected to the lower inner wall of the testing cabinet. A soil discharge hole is opened on the lower left side of the testing cabinet, and a collection plate is connected to the lower left side of the soil discharge hole. A cabinet door is opened on the upper front side of the testing cabinet, and a sealing door is rotatably connected to the lower side of the cabinet door. The sealing door can be flipped back and forth. A pushing component is installed inside the upper end of the sealing door, and a limiting support plate is installed on the rear lower side of the sealing door, with the limiting support plate connected to the lower front side of the cabinet door.
[0007] Preferably, the pushing component includes a pushing plate and a pushing roller, and the upper end of the blocking door is provided with a telescopic sliding groove, the front sides of the left and right ends of the telescopic sliding groove are connected to limit sliding grooves.
[0008] Preferably, a pusher plate is slidably connected inside the telescopic slide groove, and limit sliders are connected to the front sides of both the left and right ends of the pusher plate, and the two limit sliders are slidably connected inside the two limit slide grooves respectively.
[0009] Preferably, multiple push rollers are rotatably connected to the lower side of the inner cavity of the push tray, and telescopic holes are provided on the front side of the inner walls at both ends of the telescopic slide.
[0010] Preferably, both of the telescopic holes are slidably connected to limit heads at the end near the push plate, and both limit heads are hemispherical at the end near the push plate.
[0011] Preferably, each of the two limiting clamps is provided with a limiting spring at the end away from the push plate, and is elastically connected to the inside of the telescopic hole through the limiting spring. Two hemispherical limiting clamp holes are provided at both the left and right ends of the push plate.
[0012] Preferably, the limiting card head is engaged inside the limiting card hole and can rotate in the two limiting card holes on the same side. Multiple roller grooves are provided on both the left and right sides of the lower end of the push plate, and push rollers are rotatably connected inside the multiple roller grooves.
[0013] Beneficial effects:
[0014] 1. The lower inner wall of the testing cabinet of this utility model is set with an inclined surface that is lower on the left and higher on the right, and a soil discharge hole is opened on the lower side of the left end. A collection plate is connected below the soil discharge hole, so that the concrete debris after testing can automatically slide down and be collected in a concentrated manner, reducing the difficulty of manual cleaning and improving the efficiency of equipment maintenance.
[0015] 2. The upper end of the sealing door of this utility model is equipped with a pushing component, including a sliding pushing plate and a pushing roller. By pushing the plate, the concrete specimen is smoothly sent to the center position of the lower pressure column, reducing the difficulty of manual adjustment, ensuring accurate positioning of the specimen, improving the accuracy and efficiency of testing, and pushing the concrete specimen into the equipment through the sealing door and the pushing component reduces the limitation of operating space and improves the convenience of testing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] To achieve the above-mentioned utility model objectives, such as Figures 1-6As shown, this utility model provides a pressure testing device for concrete strength testing, including a testing cabinet 1. The lower inner wall of the testing cabinet 1 is inclined with the left side lower than the right side. A hydraulic press 2 is located at the center of the upper end of the testing cabinet 1. A hydraulic rod 3 is located inside the lower end of the hydraulic press 2, and the lower end of the hydraulic rod 3 passes through the interior of the testing cabinet 1. An upper pressure plate 4 is connected to the lower end of the hydraulic rod 3. A lower pressure column 5 is located directly below the upper pressure plate 4 and is connected to the lower inner wall of the testing cabinet 1. A soil discharge hole 6 is opened on the lower left side of the testing cabinet 1, and a collection plate is connected to the lower left side of the soil discharge hole 6. A cabinet door is opened on the upper front side of the testing cabinet 1, and a sealing door 7 is rotatably connected to the lower side of the cabinet door. The sealing door 7 can be flipped back and forth. A pushing component is located inside the upper end of the sealing door 7, and a limiting support plate 8 is located on the lower rear side of the sealing door 7 and is connected to the lower front side of the cabinet door. During the process of testing the concrete strength... In the process, the sealing door 7 is flipped forward and flipped to the upper end of the limiting support plate 8, so that the sealing door 7 is in a horizontal state, thereby opening the cabinet door of the pressure testing equipment. Then, the concrete specimen is pushed to the upper end of the lower pressure column 5 through the pushing component inside the upper end of the sealing door 7, so that the concrete specimen can be moved to the upper end of the lower pressure column 5 with less effort, reducing labor intensity, improving testing efficiency, and making it easier to adjust the position of the concrete specimen to ensure that the concrete specimen is located in the middle position of the upper end of the lower pressure column 5, ensuring testing accuracy. Then, the cabinet door is closed, and the hydraulic press 2 drives the upper pressure plate 4 to press down on the concrete specimen at the upper end of the lower pressure column 5 through the hydraulic rod 3, thereby testing the strength of the concrete. The tested concrete specimen will scatter into the interior of the testing cabinet 1 and be guided to the position of the soil discharge hole 6 through the inclined inner wall of the lower end of the testing cabinet 1, and then collected and processed by the collection plate connected to the outside of the soil discharge hole 6.
[0029] Preferably, the pushing component includes a pushing plate 11 and pushing rollers 13. A telescopic groove 9 is provided at the upper end of the blocking door 7. Limiting grooves 10 are connected to the front sides of both ends of the telescopic groove 9. The pushing plate 11 is slidably connected inside the telescopic groove 9. Limiting sliders 12 are connected to the front sides of both ends of the pushing plate 11, and the two limiting sliders 12 are slidably connected inside the two limiting grooves 10 respectively. Multiple pushing rollers 13 are rotatably connected to the lower side of the inner cavity of the pushing plate 11. Multiple roller grooves 18 are provided on both the left and right sides of the lower end of the pushing plate 11, and pushing rollers 19 are rotatably connected inside the multiple roller grooves 18. During the concrete pushing process, the concrete specimen is placed on the upper end of multiple pushing rollers 13, and then the pushing plate 11 is pushed backward. The pushing plate 11 slides backward inside the telescopic groove 9 through multiple pushing rollers 19 and fits against the front end of the pressure column 5. At this time, the concrete specimen is pushed backward, allowing the concrete specimen to move backward inside the upper end of the pushing plate 11 through multiple pushing rollers 13, and the position is adjusted during the movement. Finally, the concrete specimen is pushed to the center of the upper end of the pressure column 5, and then the pushing plate 11 is retracted, allowing the pushing plate 11 to retract back into the telescopic groove 9.
[0030] The pusher plate 11 can be connected to the blocking door 7 through the limiting slide groove 10 and the limiting slider 12, and is limited to the sliding position inside the telescopic slide groove 9 to prevent the pusher plate 11 from sliding out of the telescopic slide groove 9 and to prevent the pusher plate 11 from separating from the blocking door 7.
[0031] Preferably, telescopic holes 14 are provided on the front side of the inner walls at both ends of the telescopic slide 9. Limiting heads 15 are slidably connected inside the ends of the two telescopic holes 14 near the push plate 11, and the ends of the two limiting heads 15 near the push plate 11 are hemispherical. Limiting springs 16 are provided at the ends of the two limiting heads 15 away from the push plate 11, and are elastically connected to the telescopic holes 14 through the limiting springs 16. Two hemispherical limiting holes 17 are provided at both ends of the push plate 11. The limiting heads 15 are engaged inside the limiting holes 17 and can rotate within the two limiting holes 17 on the same side. During the backward sliding of the push plate 11, the limiting heads 15 retract into the telescopic holes 14, and the hemispherical ends of the limiting heads 15 are outside the push plate 11. As the pusher plate 11 slides along the wall, when it slides to be in contact with the front end of the lower pressure column 5, the front limiting hole 17 moves to the position of the limiting head 15. At this time, the limiting head 15, under the action of the limiting spring 16, engages with the front limiting hole 17, limiting the position of the pusher plate 11 and preventing it from moving during the pushing of the concrete specimen, thus improving the pushing safety. When the pusher plate 11 is fully retracted into the telescopic slide 9, the rear limiting hole 17 moves to the position of the limiting head 15. The limiting head 15, under the action of the limiting spring 16, engages with the rear limiting hole 17, limiting the position of the pusher plate 11 and preventing it from sliding out of the telescopic slide 9 during the upward flipping of the sealing door 7, ensuring that the cabinet door can be closed smoothly.
