Its application in the field of structural reinforcement can significantly improve the seismic performance, bearing capacity and damage resistance of the structure. The quality of concrete will directly affect the safety of the building structure. Therefore, before the concrete is put into use, it will be tested. Among them, concrete strength test is one of the multiple tests of concrete.
[0003] CN220154145U discloses a concrete strength testing device for durable concrete, which can detect the strength of multiple surfaces and multiple positions of a durable concrete test block, but does not have a structure for cleaning concrete fragments. In the existing high-ductility concrete strength testing device, during the test, the concrete test block will be squeezed into many small fragments under the action of pressure and fall into various corners of the equipment, which not only makes it very inconvenient to clean up these fragments when the test is completed, but also during the test, the concrete test block will splash around when it is squeezed and broken, so that it is easy to hit the surrounding staff, which has certain safety hazards, and the cleaning of the remaining concrete test block is more troublesome. Utility Model Content
[0004] In order to solve the above problems existing in the prior art, the utility model provides a high-ductility concrete durability testing device, which can prevent the concrete test block from splashing during the testing process and facilitate the cleaning of the concrete block after the test.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] See also Figures 1 to 3 , the utility model provides a technical solution:
[0021] A high-ductility concrete durability testing device comprises a testing box 1, a box door 2, a support plate 3 and a strength testing mechanism. The front side of the testing box 1 is an open structure. The box door 2 is rotatably installed on the front side of the testing box 1 through a hinge. An observation hole is opened on the front side of the testing box 1, and a transparent glass mirror 11 is fixedly installed in the observation hole. When performing the testing operation, the box door 2 is closed and the situation inside the testing box 1 can be clearly observed through the transparent glass mirror 11. At the same time, the closed box door 2 can effectively prevent the damage that may be caused by the splashing of broken concrete test blocks. The bottom of the support plate 3 is arranged inside the testing box 1 through a stone filtering device. A plurality of stone filtering holes are arranged on the support plate 3. The stone filtering device can discharge the concrete test blocks that are squeezed and broken during the test, so as to facilitate the subsequent cleaning of the testing box 1. A baffle plate 31 is arranged above the support plate 3. The baffle plate 31 can prevent the concrete test blocks to be tested on the support plate 3 from falling, and can also block the splashing concrete test block fragments, so as to gather the concrete test blocks onto the support plate 3.
[0022] The strength detection mechanism includes a hydraulic cylinder 4 fixed on the top of the detection box 1, and the lower surface of the hydraulic cylinder 4 is fixedly connected to a lower pressure plate 42 through a pressure sensor 41; the hydraulic cylinder 4 is started to drive the lower pressure plate 42 to move downward to pressurize the concrete test block, and the compressive strength test of the concrete test block begins. The pressure on the concrete test block is detected by the pressure sensor 41 and the result is obtained (the pressure sensor 41 is an existing well-known technology, which can sense the pressure signal and can convert the pressure signal into a usable output electrical signal according to a certain rule);
[0023] The stone filtering device includes a motor box 5 arranged on the side wall of the detection box 1, and a motor 51 is arranged in the motor box 5. The output end of the motor 51 is fixedly connected to an irregular rotating wheel 52; the stone filtering device also includes a fixed seat 53 arranged on both sides of the interior of the detection box 1, and a moving rod 54 is slidably penetrated on the fixed seat 53. The tops of the moving rods 54 on both sides are fixedly connected to the bottom of the support plate 3, and a spring 55 is sleeved on the moving rod 54. One end of the spring 55 abuts against the lower bottom wall of the support plate 3, and the other end of the spring 55 abuts against the upper surface of the fixed seat 53; the irregular rotating wheel 52 is rotated by the motor 51 to abut against the upper end of the support plate 3 and press the support plate 3 downward; a crushed stone receiving plate 56 is obliquely arranged on the lower wall surface of the detection box 1, and one end of the crushed stone receiving plate 56 obliquely downward is connected to a crushed stone discharge hopper 57, and the other end of the crushed stone discharge hopper 57 is connected to the outside of the detection box 1.
[0024] Specifically, the irregular rotating wheel 52 is rotated by the motor 51. When the raised part on the irregular rotating wheel 52 hits the surface of the support plate 3, the irregular rotating wheel 52 continues to rotate, which will press the support plate 3 downward, and then the raised part of the irregular rotating wheel 52 will move away from the support plate 3. The support plate 3 automatically rebounds under the action of the bottom spring 55 to complete the vibration of the support plate 3. This process is repeated to allow the concrete test block located on the surface of the support plate 3 to fall downward through the filter hole onto the crushed stone receiving plate 56, and then roll down to the crushed stone discharging hopper 57 until it is recovered outside the detection box 1. At the same time, a vibration motor can be provided at the bottom of the crushed stone receiving plate 56, and the repeated vibration of the vibration motor drives the concrete fragments to roll toward the crushed stone discharging hopper 57.
[0025] It is worth mentioning that when the concrete test block is heavy and the spring 55 cannot continue to shrink downward, the irregular rotating wheel 52 can be set on the lower surface of the support plate 3, which has the same effect and can drive the support plate 3 to vibrate continuously.
[0026] A dust collecting plate 6 is provided on the wall of the detection box 1, and the dust collecting plate 6 is connected to a dust collecting box 62 through a dust collecting pipe 61, and the dust collecting box 62 is fixedly connected to the outer wall of the detection box 1; a dust collecting fan 63 is provided on the upper surface of the dust collecting box 62, and a dust reduction pipe 64 is clamped on the inner wall of the dust collecting box 62; the dust collecting box 62 is filled with water; in the working process, the dust is sucked into the dust collecting box 62 through the dust collecting plate 6 by the action of the dust collecting fan 63, and the air containing dust is discharged from the bottom through the dust reduction pipe 64 clamped on the inner wall of the dust collecting box 62, and the dust is adsorbed by the water in the dust collecting box 62 after being discharged, so as to prevent the dust from floating into the working environment.
[0027] The working principle of the above-mentioned high ductility concrete durability testing equipment is as follows:
[0028] Open the box door 2, put the concrete test block to be tested on the upper surface of the support plate 3, and then start the hydraulic cylinder 4 to drive the lower pressure plate 42 to move downward to pressurize the concrete test block, and start the compressive strength test of the concrete test block. The pressure on the concrete test block is detected by the pressure sensor 41 and the result is obtained; then start the motor 51 to drive the support plate 3 to vibrate up and down continuously, shake the concrete test block onto the gravel receiving plate 56, and then roll it to the gravel discharge hopper 57 until it is recovered outside the detection box 1.
[0029] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
