Description

Paint drawing instrument for detecting anticorrosive coating of crane body Technical Field The utility model relates to the technical field of paint detection, in particular to a paint drawing instrument for detecting an anticorrosive coating of a crane body. Background The crane is also called a crane, and is an apparatus for carrying heavy objects, and is indispensable in the fields of production, processing, transportation, infrastructure, and the like. Under the general condition, most cranes are used outdoors and are subjected to wind blowing, sun drying, rain and freezing for a long time, rust easily occurs, the attractiveness is affected by light weight, the mechanical strength is affected by heavy weight, and potential safety hazards are generated. Therefore, for key parts such as a suspension arm, particularly the protection of a machine body is required, and the protection of an anti-corrosion coating is very important. In the crane production process, the corrosion-resistant coating of the crane body needs to be detected, and the current common detection method is that the adhesive force of the drawing instrument is detected. When the manual drawing instrument is operated, the detection spindle is stuck and fixed outside the anti-corrosion coating on the detection part, a circle of anti-corrosion coating around the spindle is cut off through the cutter, the influence of the anti-corrosion coating around the spindle on the detection result is prevented, the quick-dismantling drawing head of the drawing instrument is arranged on the spindle and supported on the machine body, and the spindle is pulled by negative pressure generated by the pressure regulating piston until the spindle pulls the anti-corrosion coating off the machine body, so that the adhesive force of the anti-corrosion coating is detected. At present, the quick detach pull head of many manual pull meters is directly connected on a straight line through withstand voltage connecting pipe and pressure regulating piston, receive and draw the structural limitation of appearance self, withstand voltage connecting pipe of pull meter needs to bear gas pressure, need structural strength high, often inside all have steel wire braided net intermediate layer, hardness is great, when holding pressure regulating piston, the turning handle of turning pressure regulating piston is twisted to the other hand in one hand, rocking and the swing that the operation caused are transmitted to quick detach pull head through withstand voltage connecting pipe easily for the spindle exists the influence of quick detach pull head sled external force, leads to the testing result inaccurate, uses comparatively inconveniently. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides a paint drawing instrument for detecting an anticorrosive coating of a crane body, which is used for solving the problem that the detection result is inaccurate due to easy prying external force to a spindle caused by shaking and swinging when the manual drawing instrument is operated.
