Description

Technical Field

[0001] This utility model relates to the field of flaw detectors, and in particular to a heating device for a dual-track ultrasonic flaw detector. Background Technology

[0002] Ultrasonic testing is a non-destructive testing method that utilizes the propagation and reflection characteristics of ultrasonic waves in materials to detect internal defects. It works by leveraging the principle that ultrasonic waves, when propagating through a material, are reflected or scattered upon encountering defects or interfaces. By analyzing the reflected or scattered wave signals received by the probe, information such as the presence, location, and size of defects within the material can be determined.

[0003] When inspecting rails for defects, ultrasonic flaw detectors are generally used to monitor internal damage. Ultrasonic flaw detection offers advantages such as strong penetration, safe operation, lightweight equipment, high measurement accuracy, high sensitivity, and rapid result acquisition. It can detect defects in rails such as cracks, white spots, delamination, porosity, and incomplete penetration. The principle is that ultrasonic waves propagate through the rail, and when they encounter defects (such as cracks or inclusions), they are reflected. The energy of the reflected ultrasonic waves depends on the difference in acoustic impedance between the media on both sides of the interface, as well as the orientation and size of the interface. By analyzing the energy of the reflected waves received by the probe, the size and location of the defects can be determined. Ultrasonic flaw detectors are generally classified into single-rail flaw detectors, double-rail flaw detectors, large rail flaw detection vehicles, and phased array flaw detectors.

[0004] Dual-rail flaw detectors have a relatively fast detection speed and can simultaneously inspect two parallel rails. However, the coupling agent in currently used dual-rail flaw detectors is prone to freezing and clogging in low-temperature environments such as winter. While using antifreeze as the coupling agent eliminates the freezing risk, it contaminates the rails and affects the braking performance of trains. In other words, dual-rail flaw detectors are inconvenient to use in low-temperature environments such as winter, which reduces the efficiency of rail flaw detection. Utility Model Content

[0066] Storage tank 2 is connected to the top of the frame of the flaw detector body 1, and the storage tank 2 is used to store coupling agent;

[0067] Spray assembly 3 is installed on the underside of the frame of the flaw detector body 1 and is connected to the storage water tank 2. The spray assembly 3 is used to spray coupling agent.

[0068] The heating module includes a heating cable 4 and a heating element 5. The heating cable 4 is disposed on the outside of the spray assembly 3 and is used to heat the liquid being transported in the spray assembly 3. The heating element 5 is disposed in the inner cavity of the storage tank 2 and is used to heat the liquid in the storage tank 2.

[0069] The output pipe 33 is heated by the heating cable 4, and the heating temperature does not exceed 80°C. The heating element 5 continuously provides heating, and the temperature does not exceed 60°C. The temperature of the nozzle end 34 is controlled between 20°C and 50°C to ensure that the temperature of the nozzle end 34 is constant within the set range, so as to achieve normal operation in extremely cold weather.

[0070] Furthermore, the heat tracing cable 4 and the heating element 5 should not be heated to 100°C during use to prevent the coupling agent from reaching its boiling point and generating bubbles, which would affect the flaw detection operation.

[0071] This can greatly improve the safety factor, increase the operating efficiency of the flaw detector body 1, and achieve the effect of cost reduction and energy saving.

[0072] In this technical solution, the heating module can be used to heat the coupling agent during storage and transportation separately. In low-temperature environments such as winter, it can prevent pipelines from freezing or becoming blocked, thus preventing interference with ultrasonic flaw detection, ensuring the continuity of flaw detection operations, improving flaw detection efficiency, and facilitating the use of dual-track ultrasonic flaw detectors.

[0078] Temperature sensor 61, water level detector 62, and temperature sensor 63 are respectively connected to the microcomputer controller.

[0079] In this technical solution, sensor group 6 can be used to detect temperature and water level.

[0080] The heating cable 4, heating element 5, together with the sensor group 6 and microcomputer controller, can automatically control the temperature at the nozzle end 34. Regardless of the change in the outside temperature, the nozzle is kept at a temperature above 20°C to ensure that the liquid pipeline does not freeze.

[0081] During winter maintenance, it provides continuous heating, eliminating the need to spray antifreeze into the liquid lines and avoiding problems such as coupling agent freezing and blockage, thus ensuring the continuity of flaw detection and testing operations.

[0082] Temperature sensor 61 can monitor the temperature inside the storage tank 2, water level detector 62 can monitor the water level inside the storage tank 2, and temperature sensor 63 can monitor the temperature at the nozzle end 34. This allows for cyclic monitoring of the coupling agent temperature, thus determining the temperatures inside the storage tank 2 and at the nozzle end 34. If the water level falls below the level detected by water level detector 62, an alarm is triggered and heating is stopped to ensure the safe operation of the heating cable 4 and the heating element 5.

[0083] The heat tracing cable 4 is spirally sleeved on the outside of the output pipe 33.

[0084] In this technical solution, the output pipeline 33 is heated by the heating cable 4, and the heating temperature does not exceed 80°C.

[0091] In this technical solution, the driving component 8 can provide driving force for the operation of the stirring component 7.

[0092] In use, the bidirectional power source 82 drives the transmission shaft 83 to rotate, which in turn drives multiple upper bevel gears 84 to rotate. This drives the corresponding lower bevel gears 85 to rotate, which in turn drives the rotating shaft 71 to rotate, and then drives the stirring blades 72 and the heating element 5 to rotate, thus mixing the liquid in the storage tank 2.

[0093] An auxiliary component 9 is provided in the inner cavity of the storage tank 2, and the auxiliary component 9 is connected to the stirring component 7 in a transmission manner.

[0100] The transmission gear 94 is rotatably connected to the inner wall of the storage water tank 2;

[0101] The heating element 5 is connected to two gear rings 93 distributed vertically on its side.

[0102] In this technical solution, force transmission can be achieved by utilizing transmission components.

[0103] When the heating element 5 rotates, it can drive the gear ring 93 to rotate, thereby driving the transmission gear 94 to rotate, which in turn drives the connecting gear 95 to rotate. At this time, it can drive the rotating shaft 91 to rotate, so that multiple rotating shafts 91 can rotate, thereby driving the mixing blade 92 to rotate. Together with the stirring assembly 7, it mixes the liquid in the storage tank 2, greatly reducing the dead angle of stirring and mixing and improving the efficiency of stirring and mixing.

[0104] The heating element 5 has a U-shaped cross-section.
