Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically to a concrete testing tank that prevents concrete from cracking. Background Technology

[0002] A concrete test tank is a device specifically designed to hold and test concrete. It typically has specific dimensions and shapes to facilitate standardized performance testing of the concrete. These tests may include key performance indicators such as compressive strength, impermeability, and frost resistance.

[0003] Existing concrete test chambers have a fixed volume and cannot adjust the internal space distribution to test concrete of different volumes. Furthermore, since water needs to be added to the concrete during testing to keep the surface of the test area moist, the test is closer to the actual use conditions of concrete, thereby improving the accuracy of the test. However, existing water spraying devices cannot evenly spray water onto the concrete being tested, affecting the accuracy of the test. Utility Model Content

[0004] The purpose of this invention is to provide a concrete test tank that prevents concrete from cracking, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete test chamber for preventing concrete cracking, comprising a test box, a position plate slidably connected inside the test box, lugs fixedly connected to both sides of the upper part of the position plate, a first threaded rod threadedly connected inside the front lug, the first threaded rod being rotatably connected to the inside of the test box, a first sliding rod slidably connected inside the rear lug, the two ends of the first sliding rod being fixedly connected to the inner wall of the test box, a connecting frame fixedly connected to the upper part of both sides of the test box, a moving block slidably connected to the inner wall of the connecting frame, a rotating block fixedly connected to the upper part of the moving block, a water pipe rotatably connected between the two rotating blocks, several sets of nozzles fixedly connected to the lower part of the water pipe, a curved plate fixedly connected to the outer side of one of the moving blocks, a motor fixedly connected to the outer side of the curved plate, a first rotating shaft fixedly connected to the power end of the motor penetrating the curved plate, a second gear fixedly connected to the other end of the first rotating shaft, a first gear meshing with the outer side of the second gear, the first gear fixedly connected to the outer side of the connected water pipe, and a transmission belt sleeved on the outer side of the first rotating shaft and the other side of the water pipe.

A water pipe 27 is provided. By sliding along the connecting frame 9 and moving the block 10, the water pipe 27 can be moved to the top of the concrete after concrete is added. Several sets of nozzles 28 are threadedly installed on the lower part of the water pipe 27. A curved plate 13 is fixedly welded to the outside of the moving block 10 on one side. A motor 16 is installed on the flange of the outer side of the curved plate 13. The power end of the motor 16 penetrates the curved plate 13 and is fixedly welded to the first rotating shaft 14. A second gear 15 is fixedly welded to the other end of the first rotating shaft 14. A first gear 12 is meshed with the outside of the second gear 15. The first gear 12 is fixedly welded to the outside of the connected water pipe 27. A transmission belt 17 is sleeved on the outside of the first rotating shaft 14 and the other side water pipe 27. The motor 16 drives the first rotating shaft 14, which drives the first gear 12 to rotate through the second gear 15, thereby controlling the rotation of one side water pipe 27 and driving the other side water pipe 27 to rotate through the transmission belt 17, thereby expanding the spraying area of ​​the nozzles 28.

[0020] A second threaded rod 8 is threadedly installed on the lower part of one side of the test chamber 1. A push plate 6 is rotatably installed at the tail of the second threaded rod 8. Two sets of second sliding rods 7 are fixedly welded to one end of the push plate 6. The second sliding rods 7 are slidably installed on the inner wall of the test chamber 1. By rotating the second threaded rod 8, the second sliding rods 7 drive the push plate 6 to move, thereby causing the push plate 6 to abut against the lower part of the position plate 2 to prevent the concrete from deforming the lower part of the position plate 2. A second rotating shaft 23 is rotatably installed on one side of the test chamber 1. A rotating arm 24 is fixedly welded to the other end of the second rotating shaft 23.

A torsion spring 26 is fixedly welded between the rotating arm 24 and the test box 1. The torsion spring 26 is sleeved on the outside of the second rotating shaft 23. The torsion spring 26 pulls the rotating arm 24, causing the second rotating shaft 23 to rotate, which in turn causes the push rod 25 to press the transmission belt 17, ensuring the tension of the transmission belt 17. A third threaded rod 21 is threaded inside the two sets of moving blocks 10 on one side. One end of the third threaded rod 21 is rotatably connected to the connecting frame 9, and the other end of the third threaded rod 21 is connected to the connecting frame 9. A second bevel gear 20 is fixedly welded to one end. A first bevel gear 18 is meshed between the two second bevel gears 20 at the lower part. A rotating rod 19 is fixedly welded to the upper middle part of the first bevel gear 18. By rotating the rotating rod 19, the first bevel gear 18 drives the second bevel gear 20 to rotate. The third threaded rod 21 rotates, causing one side of the moving block 10 to move along the inside of the connecting frame 9. A third sliding rod 22 is slidably installed inside the two sets of moving blocks 10 on the other side. The two ends of the third sliding rod 22 are fixedly welded to the inside of the connecting frame 9 to ensure the movement on the other side. Block 10 does not detach from the connecting frame 9; a connecting plate 31 is fixedly welded to the lower part of one side of the test box 1, four sets of support rods 29 are fixedly welded to the upper part of the connecting plate 31, a water tank 30 is fixedly welded to the upper part of the support rods 29, a water inlet pipe 32 is fixedly welded to the upper part of the water tank 30, two sets of connecting pipes 34 are fixedly welded to the side of the water tank 30 facing the test box 1, and the water pipe 27 is connected by a flexible hose through the connecting pipes 34. The water pump in the water tank 30 supplies water to the water pipe 27; a drain pipe 33 is fixedly welded to the lower side of the test box 1 to drain excess water.

[0021] Working principle: In use, rotating the first threaded rod 5 causes the lug 3 on one side to slide the position plate 2 inside the test chamber 1. Rotating the second threaded rod 8 causes the second sliding rod 7 to move the push plate 6, which then abuts against the lower part of the position plate 2, preventing the concrete from deforming the lower part of the position plate 2. This changes the spatial distribution of the test chamber 1, enabling testing of concrete of different volumes. Rotating the rotating rod 19 causes the first bevel gear 18 to drive the second bevel gear 20 to rotate, and the third threaded rod 21 to rotate, thus... The moving block 10 on one side moves along the inside of the connecting frame 9, causing the water pipe 27 to move to the upper sides of the test box 1. The water pump in the water tank 30 supplies water to the water pipe 27. The torsion spring 26 pulls the rotating arm 24, and the second rotating shaft 23 rotates, causing the push rod 25 to press the transmission belt 17 to ensure the tension of the transmission belt 17. The motor 16 drives the first rotating shaft 14, which drives the first gear 12 to rotate through the second gear 15, controlling the rotation of one side of the water pipe 27. The transmission belt 17 drives the other side of the water pipe 27 to rotate, thereby expanding the spraying area of ​​the nozzle 28.
