Description

Technical Field

[0001] The present invention relates to the technical field of concrete detection, and more specifically to a concrete detection device for highway bridge construction. Background Art

[0002] Highway bridge construction refers to a road paving method in which the highway passes through rivers and other places during the highway paving process, and the highway paving is continued through bridges. Highway bridge construction first requires the construction of the bridge. After the bridge is built, the highway can be paved on the bridge deck.

[0003] Pavement laying on highway bridges is a complex and delicate process, which mainly includes key steps such as bridge deck cleaning, elevation control, steel mesh laying, concrete construction, surface treatment and maintenance. The following is a detailed description of these steps. Bridge deck cleaning and chiseling out floating slurry and loose concrete: First, it is necessary to chisel out the floating slurry and loose concrete on the bridge deck, including the compact concrete at the root of the guardrail, to ensure the cleanliness and flatness of the bridge deck. Steel mesh laying and binding steel mesh: Tie the steel mesh according to the design drawings to ensure that the position and spacing of the steel bars meet the design requirements. Welding shear steel bars: Weld the steel mesh with the shear steel bars embedded in the beam and slab to enhance the stability and bearing capacity of the steel mesh. Adjust the thickness of the protective layer: By adjusting the height of the shear steel bars and supplementing the steel bar heads, concrete is then laid on the steel mesh and leveled. After the concrete solidifies, the construction of the bridge highway can be completed. Then, you can choose whether to lay asphalt on the top according to the actual bridge use needs.

[0004] After the construction of the bridge is completed, in order to ensure the normal use of the road surface on the top of the bridge, it is necessary to inspect the concrete laid on the top of the bridge. When inspecting the concrete, a sampling device is used to drill a cylindrical sample on the road, and then the concrete sample can be used to detect the molding of the concrete after the highway is formed, and then it can be judged whether the highway strength reaches the design value. However, the existing sampling device uses a hollow drilling device to take samples during use. However, after the sampling is completed, the sampled concrete is stuck in the hollow sampling device and is difficult to remove. The sampling device is often knocked to make the concrete sample fall off, which will cause the sampling device to deform and make the sampling device unable to be used normally. Therefore, it is not convenient to ensure the normal use of the equipment. Summary of the invention

At this time, the concrete sample that needs to be cut will rise relative to the sampling component while the sampling component continues to rotate. During the rising process of the concrete sample, the telescopic component will be pushed to contract. Then, under the action of the spring's own elastic potential energy, the limit plate and the telescopic block will have rebound potential energy, thereby jamming the concrete sample. Under the continuous action of the sampling component, the bridge deck concrete memory bridge deck will be completely penetrated. Then, the sampling component can be returned to its original position by extending the hydraulic lifting rod. Then, the concrete sampling work can be completed, which facilitates the sampling of bridge deck concrete and is convenient for users to use.

[0017] During the sampling process of the device of the present invention, the sampling point can be placed at the drainage outlet of the highway bridge, and the holes generated by the sampling can be directly used as drainage outlets, avoiding the need to fill the dug holes during the sampling process, and after the sample positioning component is away from the sampling component, the second servo motor can drive the rotating shaft to rotate and then drive the telescopic component and the connecting square tube to rotate, and then the push plate can rotate in the opposite direction to make the outer side of the telescopic sleeve close to the sampling cylinder, and then the sample positioning component can be put into the first positioning groove and the second positioning groove under the action of the push plate, and then the sampling component and the sample positioning component can be pushed into the detection hole, and then the sampling component and the sample positioning component can be driven to rotate by the first servo motor, and the inner side of the detection hole can be polished through the positioning notch, and the position of the positioning notch can be adjusted by the hydraulic lifting rod, so as to achieve the purpose of expanding the detection hole so that it can meet the needs of the drainage hole, which is convenient for users to use.
