Concrete coring drilling machine with core sample verification function

Abstract

According to the concrete coring drilling machine with the core sample verification function, before entering an inner pipe, a sample core passes through an installation groove, a power source is switched on and off at intervals according to needs by a control chip, when the power source is switched on, electric energy is transmitted across the air through an annular wireless charging base and an annular wireless power receiving coil, and therefore a single-action double-pipe drilling tool can also receive the electric energy during work circulation, and power is supplied to an internal electromagnetic repulsion mechanism. The concrete coring drilling machine is advantaged in that a pre-energy-storage capacitor is controlled to discharge to a driving coil and a moving coil by controlling on and off of a power supply, during discharging, currents flowing through the driving coil and the moving coil are equal in magnitude and opposite in direction, foot magnetic fields generated by pulse current generate electromagnetic repulsive force through interaction, the electromagnetic repulsive force acts on the moving coil, further, a diamond conical head is driven to move towards one side of the sample core, so part of the diamond conical head exceeds the mounting groove and is in contact with the peripheral surface of the sample core, the diamond conical head is driven to move on the peripheral surface of the sample core along with the movement of the drilling tool, and nicks are generated.

Description

technical field [0001] The invention relates to the technical field of road detection equipment, in particular to a concrete core drilling rig with a core sample verification function. Background technique [0002] Concrete is a very common building material in our life. It is widely used in technical fields such as building construction and road laying. Before concrete is used, it is necessary to check the concrete sample to determine whether the concrete can meet the construction requirements. The main mode of movement is to use a concrete core drill to take a specific size core from a large concrete sample for measurement. The coring machine usually adopts a single-action double-tube drilling tool. During the drilling process, the double-tube drilling tool whose outer tube rotates but the inner tube does not rotate is called a single-action double-tube drilling tool. Because the single-action double-tube drilling tool avoids the mechanical crushing of the rock core by th...

Problems solved by technology

[0003] The problem existing in the existing technology is: according to the test content, multiple sample cores need to be taken out at different locations on the site, and there is a gap in the supervision record between the sample cores taken out and the laboratory, and it is difficult to form Reliable, open, transparent and traceable sampling process records
