Problems solved by technology

However, the performance of the current flaw detection device using ultrasonic waves is relatively simple. For example, Chinese patent CN200810137486.8 discloses a rapid scanning method and device for rail tread defects. Inspection of rail head tread, left and right side rail heads, rail bottom and rail waist

Embodiment

[0029] Such as figure 1 , figure 2 Shown: an ultrasonic online detection system for rails, the equipment includes a bracket 1, a roller table 2, a rail head tread landing gear 3, a rail bottom landing gear 4, a rail head right landing gear 5, a rail head left landing gear 6, Landing gear 7 on the left side of the rail waist, No. 1 through-beam photoelectric, No. 2 through-beam photoelectric, No. 3 through-beam photoelectric, No. 4 through-beam photoelectric, rail position detection device, controller and ultrasonic detector. The roller table 2 is located on the support 1, and the roller table 2 includes an inlet port 21 and an outlet port 22. When the rail is normally detected, it enters from the inlet port 21 and goes out from the outlet port 22. It is the opposite when pouring steel. For safety protection, a rail shape sensing device 8 for sensing the shape of the rail track is provided on the bracket 1 at the inlet end 21 of the roller table 2 . The rail shape sensing de...

Abstract

The invention provides a steel rail ultrasonic on-line detection system and a control method thereof. The steel rail ultrasonic on-line detection system comprises a support, a roller way, a railhead tread undercarriage, a rail base undercarriage, a railhead right undercarriage, a railhead left undercarriage, a rail web left undercarriage, ultrasonic probes, a photoelectric correlated cell I, a photoelectric correlated cell II, a photoelectric correlated cell III, a photoelectric correlated cell IV, a steel rail position detection device, a steel rail shape detection device, a controller and an ultrasonic tester. When the photoelectric correlated cells induct a steel rail, the controller controls the corresponding undercarriage to lift or drop so that the ultrasonic probe on the corresponding undercarriage is driven to act and thus flaw detection on all parts of the steel rail is realized. When an internal defect of a steel rail is found, the steel rail position detection device outputs a specific position of the internal defect of the steel rail and flaw detection is stopped. The steel rail ultrasonic on-line detection system has the advantages of wide detection range, fast detection rate and high detection precision.

Description

technical field [0001] The invention relates to the field of rail flaw detection, in particular to an ultrasonic on-line rail detection system and a control method thereof. Background technique [0002] my country's rail traffic is busy, and the safety of rail traffic is of great importance. The quality of rails is directly related to driving safety. Defects on the rail material, such as dark cores, small cracks, voids or impurities, gradually develop into a source of fatigue through repeated loads of the wheels, and continue to expand to the inside of the rail head, so that the effective cross-section of the rail is quickly weakened, and finally A broken track will have serious consequences. [0003] In order to ensure the safety of railway transportation, the steel rails must be strictly inspected one by one before leaving the factory, and only when they meet the inspection standards stipulated by the state can they be put into use. At present, the commonly used flaw de...
