Abstract

The invention provides a pencil hardness tester for the narrow space or the inner wall of a pipeline. The pencil hardness tester comprises a structure main body, a walking mechanism, a pencil mountingsupport, an image collection device and a pressure adjusting mechanism, the pencil hardness tester is driven by the walking mechanism to enter a narrow space, the pencil mounting support is put downat a position needing to be detected, and prints of a pencil and a coating are collected by the camera, so that the convenience and the efficiency for testing the hardness of the coating are greatly improved; the contact force between the pencil and the coating can be adjusted through the pressure adjusting mechanism, it is ensured that the contact pressure is adjusted and controlled within the specification range, and then the coating hardness accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of coating hardness measuring instruments, in particular to a pencil hardness instrument for narrow spaces or inner walls of pipelines. Background technique [0002] The pencil hardness tester uses the hardness mark of the pencil to measure the hardness of the coating film. It is a mechanical type. Its advantages are small size, light weight, and the equipment is not easy to be damaged. It is convenient for hardness measurement in laboratories and construction sites. However, the current pencil hardness tester is difficult to detect in narrow spaces or on the inner wall of pipelines. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a pencil hardness tester for narrow spaces or inner walls of pipelines. [0004] In order to achieve the above object, the technical solution adopted by the present inven...
