Background
In order to ensure the normal operation of the boiler and discover potential safety hazards in the operation of the boiler in time, hammering inspection can be generally adopted, and the hammering inspection is also one of basic methods for daily boiler inspection. The hammering test in the application refers to that the hammer body with the weight of 0.5kg is used for judging the defect condition of the detected element by hammering the sound emitted by the tested original and the rebounding degree of the small hammer. If the sound emitted in the hammering process is crisp and simple, and the small hammer can rebound, the condition of the test element is considered to be good; if the hammering element generates stuffy, muddy or broken sound and the small hammer has poor bounciness, the hammering metal element can have delamination, slag inclusion and cracks inside. It is also possible that the metal surface is corroded and that the inner surface has scale built up. If the head of the rivet or bolt is struck with a whitish sound and the hammer portion feels a movement with a finger, the rivet or bolt is loose. If the rivet falls off when the rivet head is hammered, the rivet joint becomes caustic and brittle.
An important tool in the hammering inspection is an inspection hammer, and whether the structure of the inspection hammer is reasonable and adjustable is one of necessary conditions for coping with hammering inspection under different working conditions and one of technical problems to be solved in the field of boiler inspection.
