[0002] Foamed concrete is a new type of lightweight thermal insulation material containing a large number of closed pores. It is produced by mechanically foaming a foaming agent through the foaming system of a foaming machine, uniformly mixing the foam with cement slurry, and then pouring it on-site or molding it through the pumping system of the foaming machine. After natural curing, it is formed.

[0003] The foaming height of concrete determines its thermal insulation effect. Therefore, the foaming height of foamed concrete needs to be measured before use. On the construction site, a ruler is usually inserted into the foaming tank and then pulled out to measure the foaming height. This measurement method can easily cause the foamed concrete to stick to the ruler, covering the ruler's scale and affecting the ruler's secondary use. Utility Model Content

[0033] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0034] like Figures 1 to 7 As shown, this utility model provides a device for detecting the foaming height of concrete, comprising a housing 1, a measuring plate 2, a measuring plate 3, and a transmission mechanism 4. The housing 1 has a hollow structure. Each of the two opposing inner sidewalls of the housing 1 is provided with a first sliding groove 11 and a second sliding groove 12 arranged at intervals, both extending vertically. A clearance groove 13 is provided on one sidewall of the housing 1 adjacent to the first sliding groove 11. The clearance groove 13 extends vertically, and scale lines 14 are provided on both sides of the clearance groove 13. The top and bottom surfaces of the housing 1 are respectively provided with clearance openings 15 allowing the measuring plate 2 and the measuring plate 3 to pass through.

[0035] The measuring plate 2 is slidably disposed within the housing 1 to measure the falling height of the measuring plate 3. Specifically, the measuring plate 2 is slidably disposed on both sides within the first slide groove 11. A connecting block 21 is fixedly disposed on the side of the measuring plate 2 adjacent to the clearance groove 13. A horizontally disposed measuring ruler 5 is fixedly disposed on the side of the connecting block 21 away from the measuring plate 2, and the measuring ruler 5 is disposed on the outside of the housing 1. A first protruding tooth 22 is provided on the side of the measuring plate 2 opposite to the connecting block 21.

[0036] When in use, the measuring plate 2 moves up and down, and the measuring plate 2 drives the connecting block 21 to slide up and down in the clearance groove 13. The measuring scale 5 moves up and down with the connecting block 21, and the scale corresponding to the measuring scale 5 is the distance that the measuring plate 2 moves.

[0037] The measuring plate 3 is slidably disposed inside the housing 1 to measure the height difference between the top surface of the foamed concrete and the top surface of the foaming tank 6 containing the concrete. Specifically, both ends of the measuring plate 3 are slidably disposed within the second slide groove 12, and the side of the measuring plate 3 adjacent to the measuring plate 2 is provided with a second protrusion 31, which is opposite to the first protrusion 22.

[0038] The transmission mechanism 4 is connected to the measuring plate 2 and the measuring plate 3 for controlling the simultaneous and reverse movement of the measuring plate 2 and the measuring plate 3. The transmission mechanism 4 includes a first gear 41, a second gear 42, a first sprocket 43, a second sprocket 44, and a chain 45. The first gear 41 is rotatably mounted inside the housing 1 via a rotating shaft, and the first gear 41 meshes with the first tooth 22 and the second tooth 31; the second gear 42 is rotatably mounted inside the housing 1 via a rotating shaft, and the second gear 42 is positioned above or below the first gear 41 (in this example, the second gear 42 is positioned above the first gear 41), and the second gear 42 meshes with the first tooth 22 and the second tooth 31; the first sprocket 43 and the first gear 41 are coaxially and fixedly connected; the second sprocket 44 and the second gear 42 are coaxially and fixedly connected; the chain 45 meshes with the first sprocket 43 and the second sprocket 44.

[0039] The transmission mechanism 4 works as follows: Under the influence of gravity, the measuring plate 3 slides downwards. At this time, the measuring plate 3 meshes with the first gear 41 and the second gear 42. The first gear 41 and the second gear 42 rotate clockwise, causing the measuring plate 2 to move upwards. The distance that the measuring plate 2 moves is the distance that the measuring plate 3 moves. When the measuring plate 3 moves further downwards, the measuring plate 3 meshes only with the first gear 41, and the measuring plate 2 meshes only with the second gear 42. As the measuring plate 3 continues to fall, it drives the first gear 41 to rotate clockwise. The first gear 41 drives the first sprocket 43 to rotate clockwise, the first sprocket 43 drives the chain 45 to rotate, and the chain 45 drives the second sprocket 44 to rotate clockwise. The second sprocket 44 then drives the measuring plate 2 to continue moving upwards. When it is necessary to reset the measuring plate 3, simply pull down the measuring ruler 5.

[0040] In use, first fix the housing 1 above the foaming tank 6, ensuring that the housing 1 is as vertical as possible. The bottom of the housing 1 should be positioned at the opening at the top of the foaming tank 6, allowing the measuring plate 3 to fall into the foaming tank 6 under gravity, with the bottom surface of the measuring plate 3 flush with the top surface of the foaming tank 6. Before adding concrete to the foaming tank 6, release the measuring plate 3 once. When the measuring plate 2 stops moving, record the reading at scale line 14 corresponding to the measuring ruler 5. This reading is the depth H of the foaming tank 6. Then, reset the measuring plate 3 and add concrete to the foaming tank 6 for foaming. When it is necessary to measure the foaming height of the concrete, release the measuring plate 3 again. When the moving speed of the measuring ruler 5 suddenly decreases, record the reading at scale line 14 corresponding to the measuring ruler 5. The reason for the decrease in the speed of measuring ruler 5 is that the bottom of measuring plate 3 comes into contact with the top surface of foamed concrete, which creates resistance. At this time, the reading of scale line 14 is the height difference h between the top surface of foamed concrete and the top surface of foaming tank 6. Then, the height difference h is subtracted from the height H of foaming tank 6 to get the height of the foamed concrete.

[0041] To make the deceleration of the measuring plate 3 more noticeable, a floating block 32 is fixed to the bottom of the measuring plate 3. The area of ​​the bottom surface of the floating block 32 is larger than that of the bottom surface of the measuring plate 3, thereby increasing the resistance of the floating block 32 as it enters the foamed concrete. Therefore, the foaming height of the concrete needs to be calculated by adding the height of the floating block 32 to the calculation method described above.

[0042] Obviously, in order for the measuring plate 3 to fall naturally, the measuring plate 3 can be made of a material with a higher density, and the measuring plate 2 can be made of a material with a lower density.

[0043] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
