Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a concrete strength measuring machine for water conservancy projects. Background Art

[0002] Water conservancy engineering mainly studies knowledge and skills in water conservancy engineering surveying, water conservancy engineering hydrology, and water conservancy engineering reinforced concrete. In order to ensure the quality and benefits of water conservancy projects, the quality of concrete must meet the requirements. Therefore, concrete strength testing is indispensable in water conservancy projects. Currently, there are many types of concrete strength measuring machines suitable for water conservancy projects on the market, but there are still some shortcomings.

[0003] For example, in actual use, a general strength measuring machine for concrete used in water conservancy projects uses a pressure plate to test the concrete extrusion. During this process, the concrete may be unstable and its position may shift, which will affect the accuracy of the test. At the same time, dust will be generated when the concrete is squeezed. The dust will splash everywhere and be inhaled by the operators, which will affect their health. In addition, the extruded concrete will produce a large amount of gravel. If the gravel cannot be handled in time, it will affect the results of the next test. Therefore, we propose a strength measuring machine for concrete used in water conservancy projects to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a concrete strength measuring machine for water conservancy projects, so as to solve the problems that the current concrete strength measuring machine for water conservancy projects proposed in the above background technology uses a pressure plate to detect concrete extrusion. During this process, the concrete may be unstable and the position may be offset, which will affect the accuracy of the detection. At the same time, dust will be generated when the concrete is squeezed, and the dust will splash and be inhaled by the operators, which will affect the health of the operators. In addition, the concrete after extrusion will produce a large amount of crushed stone. The crushed stone cannot be handled in time, which will affect the results of the next test.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a concrete strength measuring machine for water conservancy projects, comprising:

[0006] An operating table, the operating table being directly placed on the ground;

[0007] Also includes:

[0008] A limit mechanism is symmetrically arranged on the upper side of the operating table, wherein the limit mechanism includes a fixed plate, a sliding rod, a toggle rod, a rotating disk, a cylindrical pin, a rotating arm and a limit plate.

[0015] Preferably, a cleaning brush is provided on the upper right side of the interior of the gravel box, and the cleaning brush is installed at the output end of the hydraulic rod, and the right side of the hydraulic rod is fixedly connected to the lower right side of the operating table.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the concrete strength measuring machine for water conservancy projects fixes the position of the concrete by setting a limit mechanism, so that the concrete will not deviate during the strength test, thereby improving the accuracy of the test; at the same time, a dust splashing prevention mechanism is set to effectively block the splashing of dust and protect the health of the operating workers; in addition, a gravel cleaning mechanism is set to quickly clean up the concrete crushed by the pressing plate to avoid affecting the next concrete strength test;

[0017] When the cylindrical pin is toggled to the rotating arm, the rotating arm and the fixed plate are rotatably connected, and the upper part of the rotating arm is connected to the sliding rod, that is, the cylindrical pin toggles the rotating arm, which will cause the sliding rod to move outward with the limiting plate.

[0018] 2. Set up a limit plate, a fixed protective plate and a movable protective plate. When the concrete body is limited to the left and right by the limit plate, open the hydraulic rod above the middle of the operating table. The output end of the hydraulic rod will push the pressing plate to move downward to test the extrusion strength of the concrete body. A movable protective plate is set above the limit plate, and fixed protective plates are set above the operating table. When the movable protective plate moves inward with the limit plate, the limit plate and the movable protective plate can be engaged with the fixed protective plate. In this way, when the pressing plate squeezes the concrete body, the dust is blocked by the limit plate, the fixed protective plate and the movable protective plate, and will not splash everywhere.

[0019] 3. A base plate, an electric telescopic rod, a cleaning brush and a gravel box are provided, which are placed above the base plate through the concrete body. When the concrete body is squeezed into gravel, the electric telescopic rod is opened, and the output end of the electric telescopic rod can pull the base plate to move downward. At this time, the gravel will fall directly into the inside of the gravel box, and some gravel will remain above the base plate. At this time, the hydraulic rod connected to the right side of the cleaning brush is opened, that is, the output end of the hydraulic rod will push the cleaning brush to move left and right to clean the remaining gravel above the base plate, and the gravel will fall directly into the gravel box. The outside of the electric telescopic rod is protected by a protective hose, which can prevent gravel from entering the inside of the electric telescopic rod and affecting its normal operation.

[0027] like Figure 1 、 Figure 2 and Figure 4As shown in , a fixed plate 2 is symmetrically arranged above the operating table 1, a sliding rod 3 is installed on the upper front side of the fixed plate 2, and a rotating disk 5 is also installed on the lower front side of the fixed plate 2.

A cylindrical pin 6 is provided in front of the rotating disk 5, that is, the cylindrical pin 6 will rotate with the rotating disk 5. When the cylindrical pin 6 rotates, it will contact the toggle rod 4 and the rotating arm 7 on the outer side of the front of the rotating disk 5. When the cylindrical pin 6 is toggled to the toggle rod 4, because the sliding rod 3 is fixedly connected to the top of the toggle rod 4, that is, when the cylindrical pin 6 toggles the toggle rod 4, it will push the sliding rod 3 to move inward. The inner side of the sliding rod 3 is connected to the limit plate 8, and the limit plate 8 is located on the left and right sides of the concrete body 9, that is, the limit plate 8 can move inward with the sliding rod 3 to clamp the concrete body 9, and the limit plate 8 fixes the position of the concrete body 9, so that the concrete body 9 will not deviate during the strength test, thereby improving the accuracy of the test. When the cylindrical pin 6 is moved to the rotating arm 7, the rotating arm 7 and the fixed plate 2 are rotated and connected, and the upper part of the rotating arm 7 is engaged with the sliding rod 3, that is, when the cylindrical pin 6 moves the rotating arm 7, the sliding rod 3 will move outward with the limit plate 8, so the limit plate 8 can limit concrete bodies 9 of different sizes.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown in , after the concrete body 9 is limited to the left and right by the limit plates 8, the hydraulic rod 18 above the middle of the operating platform 1 is opened, that is, the output end of the hydraulic rod 18 will push the pressing plate 19 to move downward, and the pressing plate 19 can perform an extrusion strength test on the concrete body 9.
