Description
Technical Field
The utility model belongs to the technical field of the measuring instrument, concretely relates to thick type fire retardant coating thickness tester.
Background
According to the national standard, the thickness of the thick fireproof coating is 7-45 mm. The detection mechanism needs to detect the thickness of the fireproof coating, and at present, two types of test methods are mainly adopted, namely, 1, a thick coating tester is adopted; 2. the thickness was measured with a vernier caliper. The thick paint tester is adopted, and the thick paint tester on the market is high in price and is not suitable for comprehensive popularization; adopt slide caliper to test thickness, need punch to the basement (steel sheet) on the detection face, then use slide caliper to measure thickness, the step is loaded down with trivial details, work efficiency is low.
Disclosure of Invention
To the technical problem, the utility model provides a thick type fire retardant coating thickness tester, concrete technical scheme is:
a thick fireproof coating thickness tester comprises a main body, wherein a motor and a battery are arranged in the main body, and a switch is arranged on the main body;
the drill bit is arranged on the main body, an accidental insulating material is arranged at one end, close to the main body, of the drill bit, and scales are arranged on the drill bit;
one end of the battery is connected with the motor through a wire, a wire I is arranged on the wire, and one end of the wire I penetrates through the insulating material to be connected with the drill bit; the other end of the battery is provided with a lead II, the lead II is connected with an insulating handle, one end of the insulating handle is provided with a steel needle, the lead II is connected with the steel needle, and the insulating handle is provided with a magnet;
and a short-circuit protection switch is arranged on the lead.
It is further preferred that the insulating material is rubber and the body is made of plastic.
The utility model has the advantages that:
the electric drill bit is directly used for testing the thickness, the working efficiency is improved, and after the power-off device is additionally arranged, the electric drill bit can accurately drill the surface of the steel without damaging the steel, and the testing precision can be improved. The drill with scales can be used for drilling and can also be used as a ruler for measurement; through line connection, when the drill bit contacts the surface of the steel, the power is automatically cut off, and the thickness of the coating is accurately measured.

Detailed Description
As shown in fig. 1, a thick fireproof paint thickness tester comprises a main body 1, wherein a motor 2 and a battery 5 are arranged in the main body 1, and a switch 7 is arranged on the main body 1;
a drill bit 3 is arranged on the main body 1, an accidental insulating material 4 is arranged at one end, close to the main body 1, of the drill bit 3, and scales are arranged on the drill bit 3;
one end of the battery 5 is connected with the motor 2 through a lead 11, a lead I12 is arranged on the lead 11, and one end of a lead I12 penetrates through the insulating material 4 and is connected with the drill bit 3; the other end of the battery 5 is provided with a lead II13, the lead II13 is connected with an insulated handle 8, one end of the insulated handle 8 is provided with a steel needle 10, the lead II13 is connected with the steel needle 10, and the insulated handle 8 is provided with a magnet 9;
a short-circuit protection switch 14 is arranged on the lead 11.
It is further preferred that the insulating material 4 is rubber and the main body 1 is made of plastic.
The utility model discloses the during operation, battery 5 passes through wire 11 and supplies power to motor 2, and wire I12 on the wire 11 supplies power to the drill bit, and the insulating handle 8 that the battery 5 other end set up passes through wire II13 to be connected with battery 5, is provided with magnet 9 on the insulating handle 8, is convenient for adsorb on the steel. When measuring thickness, when drill bit 3 pierces through fire prevention coating and steel contact, drill bit, steel needle form a closed circuit jointly, cause the short circuit, short-circuit protection switch 14 disconnection, and motor 2 stops after losing the power supply, can measure the thickness of fire prevention coating according to the scale on drill bit 3.
In actual measurement, a member needs to measure 15 points, one point is drilled first, the steel needle 10 is contacted with a metal surface, and the steel needle is adsorbed by the magnet 9; the measurement is then started.
