Description

Technical Field

[0001] The utility model belongs to the technical field of concrete quality detection devices, and in particular relates to a water conservancy project concrete quality detection device. Background Art

[0002] At present, concrete refers to a general term for engineering composite materials that are cemented into a whole by cementitious materials. It generally refers to cement concrete obtained by mixing cement as cementitious material, sand and stone as aggregates and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering. The quality (strength) of concrete should be tested before use to prevent unqualified concrete from being used in civil engineering, roads, bridges and water conservancy projects. Unqualified concrete used in water conservancy projects will cause safety hazards and quality accidents to the quality of the engineering structure.

[0003] The prior art water conservancy project concrete quality detection device has the following disadvantages during use:

[0004] When testing concrete masonry, people usually use handheld hammers to knock on different parts of the top of the concrete masonry for testing. However, this testing method leads to high labor intensity and lacks a structure that can automatically knock on different positions of the top of the concrete masonry, which greatly reduces the efficiency of testing. Therefore, a concrete quality testing device for water conservancy projects is needed. Utility Model Content

[0026] Example

[0027] When testing concrete masonry, it is usually done manually with a handheld hammer to perform tapping tests on different parts of the top of the concrete masonry. However, this method of testing results in high labor intensity and lacks a structure that can automatically perform tapping tests on different parts of the top of the concrete masonry, which greatly reduces the efficiency of testing.

[0029] The adjustable reciprocating knocking mechanism 5 can easily knock the top of the concrete brick 3 back and forth to detect its quality;

[0030] The intermittent pushing structure 6 can facilitate the intermittent forward pushing of the concrete brick 3 , so that the adjustable reciprocating knocking mechanism 5 can facilitate the knocking detection of different positions on the top of the concrete brick 3 .

[0031] Further as Figure 1-3 As shown, it is worth specifically explaining that, in order to facilitate the knocking inspection of the quality of concrete masonry with different thicknesses, an adjustable reciprocating knocking mechanism 5 is provided, which includes a turntable 56 fixedly connected to the outer side of the output shaft at one end of the dual-axis motor 41, a slider 55 with an I-shaped cross-section is slidably connected in a slide groove provided on the turntable 56, a transmission column 54 is fixedly connected to the front end of the slider 55, a transmission rod 52 is movably sleeved on the outer side of the transmission column 54, and the transmission rod 52 is movably sleeved on two symmetrically arranged L The outer side of the L-shaped guide rod 51, the bottom end of the L-shaped guide rod 51 is fixed to the outer side of the N-shaped support frame 4, the transmission rod 52 is provided with a transmission channel 53 which cooperates with the transmission column 54, the bottom end of the transmission rod 52 is fixed with a plurality of equidistantly arranged knocking rods 58, the bottom end of the knocking rod 58 is fixed with a knocking ball 59, the slider 55 is threadedly connected with a screw a57, both ends of the screw a57 are rotatably connected to the slide groove, the top end of the screw a57 extends to the outer side of the turntable 56, and is fixed with a handle.

[0032] The length of the transmission channel 53 is greater than the diameter of the turntable 56 , and the width of the transmission channel 53 is equal to the diameter of the transmission column 54 .

[0033] Further as Figure 1-3As shown, it is worth specifically explaining that in order to automatically push the concrete masonry forward intermittently, so that the adjustable reciprocating knocking mechanism 5 can easily knock on different positions on the top of the concrete masonry to detect the quality, an intermittent pushing structure 6 is provided, including a transmission shaft 64 fixedly connected to the outside of the other output shaft of the dual-axis motor 41, and the other end of the transmission shaft 64 is rotatably connected to the support plate 641 fixed to the top of the detection platform 1, and a sprocket a65 is fixedly connected to the outside of the extension portion of one end of the transmission shaft 64 away from the dual-axis motor 41, and the sprocket a65 is connected to the sprocket b67 through a chain 66, and the sprocket b67 is rotatably connected to the support plate 641 through a rotating shaft. A gear b632 fixedly connected to the outer side of the rotating shaft is also provided between the sprocket b67 and the support plate 641. The gear a631 is meshedly connected below the gear b632.
