Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, specifically a corrugated pipe drop hammer test device. Background Technology

[0002] A bellows is a tubular elastic sensitive element made of foldable corrugated sheets connected along the folding and stretching direction. Bellows are widely used in instruments and meters, mainly as measuring elements of pressure measuring instruments, converting pressure into displacement or force. Bellows have thin walls and high sensitivity, with a measuring range of tens of Pascals to tens of megapascals. Its open end is fixed, while the sealed end is in a free state, and it uses an auxiliary helical spring or leaf spring to increase elasticity.

[0003] In practical applications, bellows need to withstand various complex working conditions, including high temperature, high pressure, corrosive media, and mechanical impact. Among these, impact resistance is an important indicator for evaluating the load-bearing capacity and failure mode of bellows under external impact. However, the hammer in existing drop hammer devices is usually guided by a guide rail. Due to the precision and installation errors of the guide rail, the impact position of the hammer is difficult to control precisely, resulting in uneven stress on the bellows and affecting the reliability of the test results. Therefore, those skilled in the art have provided a bellows drop hammer test device to solve the problems mentioned in the background art. Utility Model Content
