Description

Technical Field

[0001] The invention relates to the technical field of concrete detection, in particular to a device for detecting performance of machine-made sand concrete. Background Art

[0002] Artificial sand concrete refers to concrete prepared with artificial sand as fine aggregate. Artificial sand is made by crushing hard rocks with professional machinery. The rock particles have a particle size of less than 4.75mm, excluding soft and weathered particles. The application background of artificial sand concrete is due to the shortage of natural sand resources and environmental damage. Artificial sand has become an alternative material. The advantages of artificial sand include wide sources and rich resources. It can be processed from a variety of waste resources, which not only solves the problem of environmental pollution, but also improves the utilization rate of natural resources. After the manufacture of artificial sand concrete, concrete performance testing is often required, and compared with ordinary concrete, sampling and testing of multiple parts are required. The current testing equipment mainly focuses on single testing. When conducting testing, a single test result is not accurate and multiple tests are required.

[0003] Regarding the above-mentioned related technologies, it is believed that: for example, when testing fluid or block-shaped machine-made sand concrete, a more stringent testing mechanism is needed to conduct a comprehensive test on the slump and pressure bearing capacity of fluid or block-shaped machine-made sand concrete. At present, the equipment is mainly based on a single testing procedure, and the testing range is small, which is not comprehensive enough for the performance test of concrete.

[0016] The present invention has the following beneficial effects:

[0017] (1) The device for testing the performance of machine-made sand concrete places a block of concrete on the middle of a placing table. The electric hydraulic rod pushes the moving seat to slide downward along the support rod, driving the pressure seat and the pressure sensor to move downward. The pressure seat applies pressure to the concrete on the top of the placing table. The pressure sensor monitors the pressure in real time. The moving seat drives the rack 1 to slide downward in the inner wall of the through groove. The rack 1 drives the transmission gear and the rack 2 to slide upward. The rack 2 drives the trapezoidal block to slide upward in the trapezoidal groove and drives the connecting seat and the U-shaped baffle to rise. The electric hydraulic rod keeps applying pressure downward to check the pressure bearing condition of the block of concrete. When the concrete is broken, the large block of concrete is directly taken out. The small block of concrete or debris is inconvenient to collect and can be directly cleaned into the slag discharge trough and discharged into the slag collecting frame through the slag discharge cavity. The pressure bearing capacity of the block of concrete can be tested. In the process of testing, the U-shaped baffle can be driven to rise to protect the staff. This can prevent part of the concrete from being crushed under pressure and causing the fragments to splash, thereby avoiding safety hazards.

[0018] (2) The performance testing device for machine-made sand concrete is as follows: a slump bucket is placed in the wall of the placement groove, and fluid concrete is added to the slump bucket in multiple times. During the filling interval, the electric push rod pushes the mounting frame and the limit rod to slide downward, and the vibrating hammer penetrates into the fluid concrete in the slump bucket to vibrate. The slump bucket is taken out from bottom to top to observe and measure the slump of the concrete. The high-pressure liquid pump draws water from the outside through the water inlet pipe and injects it into the connecting pipe and the high-pressure nozzle through the connecting hose for discharge. The electric push rod pushes the mounting frame, the L-shaped plate, the fixing seat, the connecting pipe and the high-pressure nozzle to move downward, and the sprayed water washes the surface of the test table. The sewage flows into the slag collecting pipe and then is discharged from the slag discharge port into the inside of the slag collecting frame. The slump of the fluid machine-made sand concrete can be tested. When the concrete is added, it is fully vibrated so that the concrete in the slump bucket is more evenly distributed and the test data is more accurate. After the test is completed, it can be washed clean to facilitate the next test.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] When working, firstly, the vibrator 54, the electric push rod 55, the electric hydraulic rod 61, the pressure sensor 616, and the high-pressure liquid pump 91 are connected through the external power supply and the controller. The solid concrete detection component 6 is mainly used to detect the pressure bearing capacity of the block solid concrete. The slump bucket 4, the vibration component 5 and the cleaning component 9 are mainly used to test the fluidity and water retention of the fluid concrete. The whole device can perform performance tests on concrete in two different states. When testing the block concrete, the block concrete is first placed on the middle of the placement table 613 on the top of the pressure-bearing table 2. The electric hydraulic rod 61 is controlled by the external controller to work and push the moving seat 64 to slide downward along the outer wall of the support rod 63 and drive the pressure seat 617 and the pressure sensor 61 6 moves downward, so that the pressure seat 617 and the block of concrete placed on the top of the placing table 613 are pressed, and the pressure applied by the pressure seat 617 to the block of concrete is monitored in real time by the pressure sensor 616. When the movable seat 64 slides downward, it will drive the rack 1 65 to slide downward in the inner wall of the through groove 618, and the rack 1 65 will drive the transmission gear 66 meshing with it to rotate, and then drive the rack 2 67 meshing with the transmission gear 66 to slide upward, and the rack 2 67 simultaneously drives the trapezoidal block 611 to slide upward in the inner wall of the corresponding trapezoidal groove 610 and drives the connecting seat 69 and the U-shaped baffle 68 to rise.

Soil fragments may cause harm to workers. After the pressure sensor 616 reaches the target pressure value, the electric hydraulic rod 61 always keeps the downward pressure for a certain period of time to check the pressure test of the block concrete. During the test, the internal pressure state can be seen through the transparent observation window on the U-shaped baffle 68. If the concrete is broken during the test, the large piece of concrete can be taken out directly. Small pieces of concrete or debris are inconvenient to collect and can be directly cleaned into the slag discharge trough 612 and discharged into the slag collection frame 7 through the slag discharge cavity 614. When testing the concrete in a fluid state, first put the slump bucket 4 into the inner wall of the placement groove 53, and add the fluid concrete to be tested into the slump bucket 4 in multiple times. In the gap between the fillings, In the process, the electric push rod 55 pushes the mounting frame 57 to slide downward and drives the limit rod 56 to move downward to prevent the mounting frame 57 from being offset, and drives the vibrating hammer 58 to penetrate into the fluid concrete in the slump bucket 4. The vibrating hammer 58 is controlled by the vibrator 54 to vibrate the concrete in the slump bucket 4, so that the fluid concrete in the slump bucket 4 is more evenly distributed. Each time the concrete is filled, the vibrating hammer 58 is vibrated once. The total time for the entire concrete filling and vibration should be completed within 3-5 minutes. Then the slump bucket 4 is taken out from bottom to top to observe and measure the slump of the concrete, and the concrete slump is analyzed to see whether it meets the use requirements and whether the performance meets the standards according to the concrete slump. After the test is completed, the concrete is cleaned out.Concrete impurities remain on the top wall of the test bench 3. Then the high-pressure liquid pump 91 draws water from the outside through the water inlet pipe 92, injects it into the connecting pipe 96 and the high-pressure nozzle 97 for discharge, and pushes the mounting frame 57 and the L-shaped plate 94 downward through the electric push rod 55. The L-shaped plate 94 drives the fixing seat 95, the connecting pipe 96 and the high-pressure nozzle 97 to move downward while moving downward. The water sprayed by the high-pressure nozzle 97 can clean the surface of the test bench 3. After washing, the sewage flows into the slag collecting pipe 52 and then is discharged from the slag discharge port into the inside of the slag collecting frame 7, thereby completing the performance test of the block concrete and the flowing concrete, expanding the overall test range, and being able to test concrete in different states.
