Description

Technical Field

[0001] The present invention relates to the technical field of concrete quality detection, in particular to a construction engineering concrete quality detection device and a use method thereof. Background Art

[0002] Concrete slump mainly refers to the plasticization and pumpability of concrete. The factors that affect the slump of concrete mainly include gradation changes, water content, weighing deviation of scales, dosage of admixtures, and the temperature of cement, which is easily overlooked. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. The test method of concrete slump: use a trumpet-shaped slump bucket with an upper opening of 100mm, a lower opening of 200mm, and a height of 300mm, and fill it with concrete in three times. After each filling, use a tamping hammer to hit the barrel wall evenly from the outside to the inside for 25 times. After tamping, smooth it. Then pull up the barrel, the concrete collapses due to its own weight. The height of the highest point of the concrete after collapse is subtracted from the barrel height (300mm), which is called slump. If the difference is 100mm, the slump is 100. During the test, at least two people are required to work together. For example, one person is required to press the slump while the other person cleans the concrete and mud on the ground nearby to prevent interference with the concrete slump test, which takes up more human resources.

The second fixing plate 26 is then pulled upward, so that the second fixing plate 26 drives the cone 37 upward through the second connection box 29, the screw 40, the mounting frame 39 and the mounting block 38, so that the guide column 45 moves along one end of the limiting rod 44 to prevent torsion and shaking, until the cone 37 is out of contact with the concrete cone, at which time the limiting rod 44 is disengaged from the inside of the guide column 45, and then the second fixing plate 26 and the cone 37 are placed on one side of the fixing box 1, and then the mounting seat 53 is pulled out, so that the steel belt 52 is released from the outside of the winding roller 50, so that one end of the limiting seat 60 is inserted into the mounting groove 54, and at this time the second magnetic block 61 and the first magnetic block 58 are The magnetic attraction between them causes the first magnetic block 58 to drive one end of the fixing rod 57 to be inserted into the limiting seat 60, and the position of the mounting seat 53 and the steel belt 52 is limited. Then the ruler 66 is taken out and used vertically. The ruler 66 is placed on one side of the steel belt 52 to measure the highest point of the concrete cone after collapse, and the record is made. Then the operator pulls the unlocking rod 56, so that the unlocking rod 56 drives the fixing rod 57 and the first magnetic block 58 to move out of the limiting seat 60. Then the operator moves the mounting seat 53, so that the spring 51 drives the winding roller 50 to reset and rotate, so that the winding roller 50 rewinds the steel belt 52, so that the steel belt 52 drives the mounting seat 53 to reset and move to the initial position. Step 4: According to the above steps, the conveyor belt 6 is reeled in by the first roller 4, and the concrete on the surface of the conveyor belt 6 is cleaned and collected in the collecting bin 9 until the rotating rod 14 cannot be rotated. Then the operator resets and rotates the connecting rod 22, so that the connecting rod 22 drives the first threaded rod 20 to rotate through the second bevel gear 23, so that the first threaded rod 20 drives the top end of the first limit block 21 to be inserted into the guide rail 25. Then the operator resets and rotates the rotating rod 14, so that the second roller 5 reels the conveyor belt 6 until the moving block 24 touches the first limit block 21. At this time, the rotating rod 14 cannot continue to rotate, so that the middle part of the conveyor belt 6 is in the use position, and then the collecting bin 9 is taken out, and the concrete inside the collecting bin 9 is taken out for recycling. Then the second fixed plate 26 is placed on the top of the fixed box 1, and then the protective box 68 is closed, and the protective box 68 is fixed to the fixed box 1. Then the device can be pulled to move.
