Technical Field

[0001] This utility model belongs to the technical field of concrete testing equipment, specifically a convenient tester for concrete impact and abrasion resistance. Background Technology

[0002] In fields such as water conservancy and construction, concrete structures are subjected to long-term erosion by water flow and sediment abrasion. Their erosion resistance is a key indicator for assessing structural durability and safety. Accurate and efficient testing of concrete erosion resistance is of great significance for optimizing engineering design, controlling construction quality, and subsequent maintenance.

[0003] Currently, concrete impact and abrasion strength testing equipment on the market has many limitations. On the one hand, traditional testing equipment is often bulky and heavy, lacking a convenient mobile structure, making it very inconvenient to transport between different testing points on the construction site, especially in complex terrain such as water conservancy projects, where the difficulty of transportation is even greater, seriously affecting testing efficiency. On the other hand, existing equipment mostly uses welded fixed connections, making it impossible to flexibly adjust the distance between the impact tank and the top plate, greatly hindering the smooth progress of feeding operations. This fixed structure restricts the user's operating space when loading materials, not only increasing the difficulty of the work but also reducing the overall testing efficiency. Utility Model Content

Connecting plates are fixedly connected to the top and bottom of the cylinder surface. The inner side of the support leg is fixedly connected to the connecting plate. The surface of the electric telescopic rod is fixedly connected to the inside of the connecting plate.

[0019] refer to Figure 2 Both sides of the lifting plate 43 are fixedly connected to sliders 7, and both sides of the inner wall of the housing 41 are provided with sliding grooves 8, which are slidably connected to the sliders 7.

[0020] In this embodiment, the sliders 7 on both sides of the lifting plate 43 are slidably connected to the grooves 8 on the inner wall of the housing 41. When the lifting mechanism 4 is running, the sliders 7 can guide and limit the movement of the lifting plate 43, ensuring that the lifting process is smooth and stable, avoiding jamming or deviation, and enhancing the stability and accuracy of the lifting mechanism 4.

[0022] In this embodiment, the transmission shaft 32 is connected to the horizontal plate 103 by a fixed bearing 9. This not only does not affect the rotation of the transmission shaft 32, but also fixes and supports the transmission shaft 32, reduces the shaking when the transmission shaft 32 rotates, ensures that the stirring blade 34 works stably in the grinding tank 33, and improves the stability of the anti-grinding strength device 3.

At the same time, it ensures the stability of testing conditions such as pressure inside the grinding tank 33, thus ensuring the accuracy of the test results.

[0025] refer to Figure 2 The housing 41 is fixedly connected to the inside of the support leg 102, and the top of the support leg 102 contacts the bottom of the horizontal plate 103.

[0026] In this embodiment, the housing 41 is fixed to the inside of the support leg 102, and the top of the support leg 102 contacts the bottom of the horizontal plate 103. This not only provides support for the housing 41 and the horizontal plate 103, but also optimizes the overall structural layout of the equipment, enhances the stability of the frame 1, and makes the equipment more stable and reliable during operation.

[0027] This invention uses casters 105 at the bottom of the frame 1 to move the equipment to the required testing position. Once in position, the cylinder 51 in the fixing mechanism 5 is activated. The output end of the cylinder 51 pushes the support insertion rod 52 downward until it is inserted into the ground, thus stabilizing the equipment and preventing movement during testing. Next, the loading operation is performed. The lifting mechanism 4 is activated by controlling the housing 104, and the electric telescopic rod 42 operates. Its output end drives the lifting plate 43 to move up and down inside the housing 41. The sliders 7 on both sides of the lifting plate 43 slide along the grooves 8 on the inner wall of the housing 41 to ensure a smooth lifting process. The lifting plate 43 drives the horizontal plate 103 to move up and down through the support legs 44, thereby adjusting the distance between the horizontal plate 103 and the grinding tank 33 on the base 101, providing sufficient space for loading and facilitating the user to place the concrete specimen into the grinding tank 33. After loading is completed, the horizontal plate 103 is adjusted again by the lifting mechanism 4. Positioning the horizontal plate 103 so that the sealing pad 10 at the bottom of the horizontal plate 103 contacts the grinding tank 33, enhancing the sealing between the two. At the same time, the auxiliary positioning mechanism 6 can be operated to assist in fixing the grinding tank 33 through the connecting plate 61, connecting rod 62 and auxiliary positioning rod 63, further ensuring its stability. When the water supply is interrupted, the backup water supply mechanism 2 is activated. The water pump 21 draws the backup water from the water tank 23 through the connecting pipe 22, and then delivers the water to the grinding tank 33 through the pipe 24 to provide the required water flow environment for testing. The water tank 23 serves as a backup water storage device to ensure that water supply can continue even when the water supply is interrupted. Finally, the motor 31 in the impact and abrasion strength tester 3 is activated. The output end of the motor 31 drives the transmission shaft 32 to rotate. The transmission shaft 32 rotates stably under the support of the fixed bearing 9. The stirring blades 34 on its surface rotate accordingly in the grinding tank 33, simulating the effects of water flow scouring and mud and sand abrasion, and testing the impact and abrasion strength of the concrete specimen.
