Description

Bellows hole detection device Technical Field The utility model relates to the technical field of corrugated pipe detection, in particular to a corrugated pipe hole detection device. Background The corrugated pipe is a tubular elastic sensitive element with a folding corrugated sheet structure and can be connected along the folding and stretching directions. The corrugated pipe is mainly divided into two major categories of metal corrugated pipes and nonmetal corrugated pipes, and the materials comprise stainless steel, copper, aluminum, rubber, plastics and the like. The pipe has good flexibility and adaptability due to the unique structure, and can be easily installed in complex space layout. The utility model discloses a bellows detection device, including detecting body and pressure testing pole, the pressure testing pole is worn out downwards and is detected the body and be connected with hexagon nut, still is provided with the pressure testing pad between this hexagon nut and detecting the body the bellows is established to the cover on the pressure testing pole, be provided with first O type circle between the upper end of bellows and the pressure testing pole, the lower extreme of bellows stretches into detect originally in and seal through sealing gasket form airtight cavity between pressure testing pole and the bellows still set up the screw thread inlet port on the detecting body, this screw thread inlet port with the cavity is linked together. The above device measures the bellows by the principle of tightness, but it needs to ensure a good seal at the interface, otherwise it can lead to deviations in the measurement results. Therefore, it is necessary to provide a bellows hole detection device to solve the above technical problems. Disclosure of utility model Aiming at the situation, in order to overcome the defects in the prior art, the utility model provides the corrugated pipe hole detection device which can measure whether a corrugated pipe has holes or not in a mechanical probe mode. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The corrugated pipe hole detection device comprises detection frames placed in the corrugated pipe, wherein at least two groups of detection frames are arranged, and two adjacent groups of detection frame supports are connected through a central rod; The detection frame comprises a central disc, at least two telescopic rods are arranged on the central disc, telescopic probes are arranged on the telescopic rods, and probes at the ends of the probes are kept in contact with the inner wall of the corrugated pipe; the center rod is provided with threads; the center plate is provided with a mounting hole for the center rod to pass through and be in threaded connection with. Preferably, a limiting piece is fixedly arranged on the probe of one of the detection frames, and each probe on the rest detection frames is positioned in a different plane. Preferably, a base is arranged in the telescopic rod, an installation seat is slidably installed in the base, the probe is detachably arranged on the installation seat, and a spring is arranged between the probe and the base.
