Description

Technical Field

[0001] The utility model relates to the technical field of asphalt concrete core wall detection, in particular to a tool for coring an asphalt concrete core wall. Background Art

[0002] Asphalt concrete core wall coring refers to the process of coring on the asphalt concrete core wall. Asphalt concrete core wall refers to the asphalt concrete wall used to separate different structural layers in building structures such as roads or bridges. In order to detect the quality and performance of asphalt concrete core wall, coring detection is required.

[0003] After searching, a Chinese patent with announcement number CN217106911U discloses a portable coring device for geological exploration, which drives two first rotating shafts to rotate through a dual-axis motor, so that two first bevel gears symmetrically arranged at both ends of the first rotating shaft rotate in opposite directions, so that the two spur gears drive the rack and the movable plate to move toward each other, so that the two movable plates at the bottom of the coring groove open or close the coring groove, and the coring groove is opened after the coring rod penetrates into the specified depth, and the soil at the specified depth is cored, so that soil of different depths will not be mixed in the coring groove, and the coring result will be more accurate.

[0004] When the above patent is in use, a coring machine is used for cutting. Since the gap cut by the coring machine is small, only about 5 mm, the excess mechanical parts cannot enter the seam surface, and the coring cannot be completed, resulting in a poor use effect. Utility Model Content

[0005] The utility model provides a tool for coring an asphalt concrete core wall, aiming to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0018] It can be seen that in the above technical solution, when the shaft rotates forward, the shaft can drive the first gear to rotate, and the first gear drives the block to move horizontally, thereby driving the two springs to compress. Similarly, the shaft rotates in the opposite direction to drive the two springs to stretch, thereby simply limiting the shaft.

[0019] The utility model has the following advantages:

[0020] 1. The utility model drives the rotating shaft to rotate by rotating the handle, and then drives the second gear to rotate. The second gear can drive the two tooth plates to move toward each other, thereby driving the two connecting frames to move toward each other, and then driving the two coring plates to move toward each other. The core sample is clamped by the two coring plates, and then the handle is moved upward to drive the core sample to move upward. Similarly, the reverse handle makes the two coring plates move away from each other. The operation is simple, coring is convenient, and the use effect is good;

[0021] 2. The utility model releases the fixation between the vertical plate and the connecting frame by rotating the threaded sleeve and moving it away from the threaded rod, so as to inspect and replace the coring plate. At the same time, the distance between the coring plate and the connecting frame can be adjusted according to needs, and then the threaded rod is inserted into the corresponding slot. Finally, the threaded rod is limited by two threaded sleeves, so that the coring plate and the connecting frame are fixed. The operation is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
