Description

Technical Field

[0001] The invention relates to the technical field of concrete drilling sampling, in particular to a concrete drilling sampling device. Background Art

[0002] Automatic concrete coring machine is a kind of equipment specially used for drilling holes in concrete structures and obtaining core samples. It is widely used in construction projects, roads, airports, ports, docks, dams and other fields to test and evaluate the quality of concrete. This type of equipment usually uses gasoline engines as the power source and is particularly suitable for on-site operations.

[0003] The coring machine in the prior art is mainly composed of a gasoline engine, a manual lifting mechanism, a mounting frame and a drill bit. When working, the gasoline engine is started to drive the drill bit to rotate, and the manual lifting mechanism is used to drive the drill bit and the gasoline engine to move downward, so as to drill into the concrete and take samples. While sampling, water is sprayed to cool the drill bit.

[0004] After drilling and sampling, the current core drilling machine needs to knock the drill bit or use a picking device to take out the sample inside the drill bit, which is not only troublesome to take samples, but also causes damage to the drill bit when knocking. In addition, the drill bit needs to be cleaned manually after drilling to facilitate the maintenance of the drill bit. However, manual cleaning is time-consuming and labor-intensive, which reduces the cleaning efficiency and then reduces the maintenance efficiency.

[0005] An automatic concrete drilling and coring device with publication number CN118464524B comprises: a mobile chassis for providing an installation position, a lifting mechanism located above the mobile chassis for providing lifting conditions, a drilling installation mechanism located on the lifting mechanism for drilling and sampling, a cooling and cleaning mechanism located below the lifting mechanism for cleaning and preventing debris splashing and dust generation during drilling, and having a cooling effect, and a disassembly and assembly mechanism located outside the drilling installation mechanism for connecting and installing and disassembling. The drill tube is driven to rotate by starting the engine, and after the drill tube samples, it is moved upward to block the fixed plate with a soft brush and a connecting column, thereby facilitating sampling and avoiding damage to the drill tube, thereby improving cleaning efficiency and maintenance efficiency.

[0006] The above equipment takes up a large space as a whole when not in use, which is convenient for storage. It cannot quickly adjust the drilling depth and is not conducive to ensuring the adjustment of the core drill bit position, so it needs to be improved. Summary of the invention

[0007] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a concrete drilling sampling device.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:
