Description

Technical Field

[0001] The present application relates to the technical field of concrete detection devices, and particularly to a concrete quality detection device based on impact elastic waves. Background Technique

[0002] Concrete is a general term for composite materials configured by gel materials, aggregates, and water in appropriate proportions and hardened after a certain period of time. It is the most widely used artificial civil engineering material in the world. Classified by use, concrete can be divided into structural concrete, mass concrete, waterproof concrete, heat-resistant concrete, expansive concrete, radiation-proof concrete, road concrete, etc. Concrete has high hardness, wide raw material sources, and low cost, and is widely used in structures such as houses, roads, military projects, and nuclear power plants. During the production process of concrete, its quality needs to be detected.

[0003] For example, a concrete quality detection device based on impact elastic waves disclosed in Chinese Patent (CN214845006U) includes a mounting frame, a wire winding rod, a first rotating rod, and a second rotating rod. Inside the mounting frame, a sensor and a sleeve are respectively fixed through a longitudinal movement mechanism. Three first fixing plates are respectively fixed on the upper inner wall of the mounting frame. An iron ball is fixed on the rod wall of the wire winding rod through a pull rope. A clutch mechanism is fixed between the left end of the wire winding rod and the right outer side wall of the sleeve. Two second fixing plates are respectively fixed on the upper surface of the mounting frame. A one-way transmission mechanism is fixed between the left end of the second rotating rod and the right end of the first rotating rod. This utility model can quickly perform multi-point detection on a concrete road surface, effectively improving the detection efficiency.

[0004] The above solution still has the following technical defects. The above solution has a relatively high requirement for the release speed of the pull rope. Since the iron ball falls under the action of gravity, the falling speed will continuously increase during the falling process, and there will be a certain resistance to the release of the pull rope. When the falling speed of the iron ball exceeds the release speed of the pull rope, the iron ball will cause energy loss due to the tension of the rope, thereby affecting the test results. Based on this, a concrete quality detection device based on impact elastic waves is proposed. Summary of the Utility Model

[0016] Adopting the above technical solution, it can automatically release the iron ball.

[0017] Further, a chute is provided on one side of the inner wall of the installation box, and the sliding rod slides in the chute.

[0018] With the above technical solution, the slider can be limited to prevent it from rotating together with the first screw rod and the second screw rod.

[0019] Further, both ends of the placement plate are respectively fixed to the opposite sides of the two sliders, and a circular hole is provided inside the placement plate.

[0020] With the above technical solution, it is convenient for the iron ball to fall after being released.

[0021] Further, the first transmission assembly includes a first driving wheel fixed on the outer surface of the first screw rod, a first driven wheel fixed on the outer surface of the second screw rod, and a first transmission belt drivingly connected to the outer surfaces of the first driving wheel and the first driven wheel.
