Embodiment 1

[0087] The corrugated pipe with a PE inner pipe diameter of 1600mm currently destroys the pipe wall at the trough of the standard corrugated pipe, and the total thickness of the standard corrugated pipe wall is 18mm measured with a vernier caliper. At this time, the distance from the first position sensor 1 to the surface at the trough of the standard bellows is 80 mm. The distance 80mm is set by the main controller as the total thickness value of the standard corrugated pipe wall, that is, 18mm. When the online detection device detects the wall of the corrugated pipe to be tested, the first position sensor 1 detects that the distance from the surface of the corrugated pipe trough to the first position sensor 1 is 78 mm, and when the data passes through the main controller, the main controller will The distance from the surface at the trough of the corrugated pipe to be measured to the first position sensor 1 is subtracted from the distance from the first position sensor 1 to ...

Embodiment 2

[0092] The corrugated pipe with a PE inner pipe diameter of 1600mm currently destroys the pipe wall at the trough of the standard corrugated pipe, and the total thickness of the standard corrugated pipe wall is 14mm measured with a vernier caliper. At this time, the distance from the first position sensor 1 to the surface at the trough of the standard bellows is 80 mm. The distance 80mm is set by the main controller as the total thickness value of the standard corrugated pipe wall, that is, 14mm. When the online detection device detects the wall of the corrugated pipe to be tested, the first position sensor 1 detects that the distance from the surface of the corrugated pipe trough to the first position sensor 1 is 79mm, and when the data passes through the main controller, the main controller will The distance from the surface at the trough of the corrugated pipe to be measured to the first position sensor 1 is subtracted from the distance from the first position sensor 1 to t...

Abstract

The invention discloses a corrugated pipe quality detection system and a detection method. The corrugated pipe quality detection system comprises a host and a display screen which is connected with the host. The corrugated pipe quality detection system further comprises an on-line detection device, a data processing device used for converting and transmitting data obtained by an inductive sensor, and a master controller. The inside of the on-line detection device is provided with an inductive sensor and two position sensors, wherein the inductive sensor is used for detecting the position of an inner-layer steel band of the trough of a corrugated pipe, and the two position sensors are used for detecting the position state of the corrugated pipe. The data processing device is connected with the inductive sensor. The master controller is connected with the data processing device, the two position sensors, and the host. The corrugated pipe quality detection system provided by the invention can detect the thickness of top plastics of a corrugated pipe, the thickness of bottom plastics of the corrugated pipe, the overall thickness, and the displacement of threads in real time, is cost-saving, high in operability and convenient to install, and has very high repeated accuracy and practicality.

Description

technical field [0001] The invention relates to the field of bellows quality detection, in particular to a bellows quality detection system and a detection method thereof. Background technique [0002] The existing steel belt reinforced spiral corrugated pipe is mainly composed of three layers: PE inner layer pipe, ring corrugated steel belt reinforcement wrapped around the inner layer tube and PE layer compounded on the periphery of the corrugated steel belt reinforcement, thus composited into a whole Spiral bellows. The inside of the ring-shaped corrugated steel belt reinforcement is a U-shaped steel belt after bending. The top of the bulge is the crest of the corrugated tube, and the bottom end combined with the PE inner tube is the trough of the corrugated tube. The upper and lower surfaces of the steel belt at the crest and trough have polyethylene outer layers, that is, plastic layers, and the crest and trough are integrated, so the thickness of PE plastic on the uppe...
