Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.

Example 1:

please refer to fig. 1-3, an adjustable lifting anti-drop concrete coring device, which comprises a top cover 1, the bottom of the top cover 1 is provided with a sleeve 2, the bottom of the sleeve 2 is provided with a coring barrel 3, the top of the inner cavities of the top cover 1 and the sleeve 2 is provided with an inner wire, the top of the sleeve 2 is provided with a first wire ring 4 positioned in the inner cavity of the top cover 1, the top of the coring barrel 3 is provided with a second wire ring 5 positioned in the inner cavity of the sleeve 2, the two sides of the lower end of the coring barrel 3 are provided with anti-drop grooves 6, the top of the top cover 1 is welded with a long rod 7, the top of the long rod 7 is provided with a horizontal rod 8, the number of the sleeve 2 is adjusted according to the thickness of the concrete structure layer, thereby adapting to the sampling of the concrete structure layers with different thicknesses, the anti-drop grooves 6 are used for limiting the drop of the core sample, thereby achieving the purpose of conveniently and completely taking out the large-thickness concrete core sample.

Referring to fig. 3, the diameter and the thread pitch of the first thread ring 4 and the second thread ring 5 are the same, so that the core barrel 3, the sleeve 2 and the top cover 1 can be matched and connected with each other, the adjustment randomness is larger during use, and the practicability is improved.

Referring to fig. 2, the two anti-drop grooves 6 are symmetrically arranged at the central parts of the two sides of the core barrel 3, so that the anti-drop grooves 6 can play a better limiting role in the central part of the core sample inside the core barrel 3.

Referring to fig. 1, the anti-drop groove 6 is shaped like an isosceles triangle, the side length of the bottom of the anti-drop groove 6 is greater than the radius of the core barrel 3, and the triangular anti-drop groove 6 can increase the friction resistance to a greater extent, thereby achieving the effect of stably preventing the core sample from dropping.
