[0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of trains and railway technologies, There are more and more types of rail transportation, not only in long-distance land transportation, the original ultrasonic device does not have cleaning equipment, because foreign objects will adhere to the surface of the rail, this will reduce the accuracy of detection

The invention belongs to the technical field of steel rail detection, and particularly relates to an ultrasonic device for nondestructive testing of a steel rail. The device comprises a supporting frame, a detector is installed in the middle of the top of the supporting frame, rubber wheels are installed at the two ends of the bottom of the supporting frame, steel rail wheels are installed on one sides of the rubber wheels, a protection frame is installed at one end of the supporting frame, and a clamping tooth disc is installed in the middle of the interior of the protection frame. A cleaning brush can clean the surface of the steel rail by switching on a power supply of a motor, and when the cleaning brush does not need to be used, an operation disc can be rotated reversely to move the cleaning brush and the motor into the protection frame, so that the cleaning brush and the motor can be prevented from being damaged. An electric push rod can be matched with a connecting shaft, so that the two rubber wheels, close to one side of the steel rail, of the supporting frame are separated from the ground, then a worker pushes the auxiliary wheels, the supporting frame is moved to the position over the steel rail, and therefore the step that the worker carries the ultrasonic device can be avoided.
Description
technical field [0001] The invention belongs to the technical field of rail detection, and in particular relates to an ultrasonic device for nondestructive detection of rails. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of trains and railway technologies, There are more and more types of rail transportation, not only in long-distance land transportation, the original ultrasonic device has no cleaning equipment, because foreign objects will adhere to the surface of the rail, which will reduce the accuracy of detection. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology. The invention provides an ultrasonic device for non-destructive detection of rails, which has the...
