Description

Concrete anticorrosion detector

Technical Field

Background

Concrete is a general term for engineering composite materials in which aggregate is cemented into a whole by a cementing material. The term concrete generally refers to cement as a cementing material and sand and stone as aggregate; the cement concrete, also called as common concrete, is obtained by mixing with water (which may contain additives and admixtures) according to a certain proportion and stirring, and is widely applied to civil engineering. Concrete materials are alkaline materials and generally do not suffer from corrosion by alkaline substances. However, in chemical enterprises, concrete materials are also damaged by long-term exposure to high-concentration alkaline substances. Concrete materials have a weak resistance to acids. For example, carbonic acid reacts with calcium hydroxide to form soluble calcium bicarbonate. Therefore, the carbonic acid has a great corrosiveness to the concrete, namely, the carbon dioxide in the air causes corrosion to the concrete material, and therefore, the corrosion resistance of the concrete needs to be detected in the production process of the concrete.

The specific working process is as follows:

when the concrete is subjected to anti-corrosion detection, the box cover 13 is firstly opened, then, the prepared concrete experiment block is placed on the placing plate 3 in the detection box 1 through the telescopic arm 52 and the hook 53, the placing plate 3 is pressed down through the gravity of the experiment block, so that the placing plate 3 and the experiment block enter the acid liquid for detection, then, the box cover 13 is closed, the detection progress is checked through the observation window 14 on the box cover 13, and the concrete block is prevented from being exposed in the external environment during detection to influence the detection process, so that the detection result has errors; after the test is completed, the box cover 13 is opened, the test block is taken out through the telescopic arm 52 and the hook 53, the acid solution in the test box 1 is discharged, when the test block is placed, the placing plate 3 is pressed down by the gravity of the test block, so that the piston rods 153 of the water pressure pump 15 and the air pressure pump 16, which are fixedly connected to the placing plate 3, move downward, the compression spring 154 is compressed, the water and the air in the external water tank are respectively pumped into the water pressure pump 15 and the air pressure pump 16 through the water inlet pipe 151 on the water pressure pump 15 and the air inlet pipe 161 on the air pressure pump 16, after the test block is taken out, the piston rod 153, which is fixedly connected to the placing plate 3, starts to move to the original position under the action of the compression spring 154, the water and the air in the water pressure pump 15 and the air pressure pump 16 are pressurized into the pressure tank 12, the pressure in the pressure tank 12 is increased, and the water in the pressure tank 12 enters the water flow channel 121 through the, and is sprayed out through a first water spraying port 171; when a concrete block enters the detection box 1, the concrete block extrudes the arc-shaped expansion plate 34 when the concrete block just begins to contact the arc-shaped expansion plate 34, the arc-shaped expansion plate 34 is arranged on the movable plate 341, therefore, the movable plate 341 is pushed to move towards the direction far away from the placing plate 3, so that the vertical expansion plate 342 extrudes the second stopper 42, the second stopper 42 moves towards the inside of the first cavity, the space in the first cavity is compressed, the pressure in the first cavity is increased, the arc-shaped expansion plate 34 is increasingly extruded by the concrete block along with the continuous downward movement of the concrete block, when the lower surface of the concrete block contacts the placing plate 3, the extrusion action of the concrete block on the arc-shaped expansion plate 34 reaches the maximum, at the moment, the second stopper is completely retracted into the first cavity, the medium pressure in the first cavity reaches the maximum and is greater than the pressure in the space close to the inner side of the detection box 1 in the second cavity, meanwhile, the placing plate 3 is positioned above the telescopic rod 35, the second stopper 42 is extruded by the vertical telescopic plate 342, and reaches the maximum pressure value, the expansion link 35 still keeps the extension state and is not pressed downwards by the placing plate 3, so that the first block 4 is blocked and cannot be extended out immediately, when the extrusion effect of the vertical expansion plate 342 on the second block 42 reaches the maximum value, the lower surface of the placing plate 3 just contacts with the top end of the expansion rod 35, while the placing plate 3 continues to descend, the telescopic rod 35 is pressed downward by the placing plate 3, starts to contract, when the placing plate 3 descends until the upper surface of the placing plate 3 is just lower than the lower surface of the first stopper 4, the stopper of the first stopper 4 disappears, therefore, the first stop block 4 rapidly extends out under the action of increased pressure in the second cavity, the placing plate 3 is stopped, and the placing plate 3 is prevented from moving upwards; when the detection is completed and the experiment block is taken out, the extrusion effect of the experiment block on the arc-shaped expansion plate 34 is gradually smaller until the experiment block is just separated from the arc-shaped expansion plate 34, the extrusion effect of the experiment block and the arc-shaped expansion plate 34 disappears, the second stopper 42 can completely return to the original position under the pressure effect in the first cavity, so that the pressure value in the second cavity is reduced, the first stopper 4 is retracted to the original position under the higher pressure in the space close to the inner side of the detection box 1 in the second cavity, after the first stopper 4 returns to the original position, the piston rod 153 fixedly connected to the placing plate 3 rapidly moves upwards under the action of the compression spring to drive the placing plate 3 to rapidly return to the original position, water and gas in the water pressure pump 15 and the gas pressure pump 16 are pressurized into the pressure tank 121 in a very short time, and the water in the pressure tank 121 is rapidly sprayed out due to the rapidly increased pressure in the pressure tank 121; when the experiment block is placed, the placing plate 3 is moved downwards under the action of the gravity of the experiment block, and the pull rope 25 is fixedly connected to the placing plate 3, so that when the placing plate 3 moves downwards, the pull rope 25 is pulled to drive the rolling brush 29 to move in the mounting seat 2 and extrude the spring 23 in the mounting seat 2 for energy storage, and then in the process that the placing plate 3 returns to the original position, the pull rope 25 is continuously loosened, and under the action of the spring 23 in the mounting seat 2, the rolling brush 29 starts to return to the original position; since the rack 21 arranged in the mounting seat 2 is meshed with the gear 28 on the rolling brush 29, the rolling brush 29 continuously rotates in the process that the rolling brush 29 returns to the original position; the horizontal hairbrush arranged on the side surface of the placing plate 3 can clean the inner wall of the detection box 1 right below the water pressure pump 15 and the air pressure pump 16 in the process of moving the placing plate 3 up and down; after the experiment, when cleaning detection case 1, spun rivers can be washed cleanly with impurity with placing board 3 remaining acidizing fluid in the surface in setting up two 321 water jet on cushion 32, guarantee to place board 3 clean and tidy, avoid placing board 3 clean not thorough, influence detection case 1 and use next time.
