Abstract
The invention relates to the elevator component non-destructive test field, and provides an ultrasonic multi-probe immersion coupling detection method for a rope fastening seam; and a digital ultrasonic detector is adopted in the method to perform location detection on the detected rope fastening seam. The method is characterized in that an ultrasonic immersion focusing probe is fixed on a locating rack in detection, and the locating rack is immersed in a solution tank which is filled with a couplant; in detection, a rope fastening workpiece is inserted into the locating rack which is immersed in the couplant in the solution tank for location, a seam on the rope fastening workpiece is placed on a fixed position opposite to the ultrasonic immersion focusing probe, and the welding seam is detected with the ultrasonic immersion focusing probe which is connected with the digital ultrasonic detector. The invention optimizes the method for detecting the welding seam quality of the rope fastening workpiece, and provides the feasible detection method for 100% detecting the quality of rope fastening workpiece seams of elevators.
Description
technical field [0001] The invention relates to the field of non-destructive testing of elevator accessories, in particular to the field of a quality testing method and a device for a weld seam of an elevator rope head combined workpiece. Background technique [0002] The rope end combination for elevator is a key component connecting the elevator running wire rope, and the quality of the rope end combination is related to the overall elevator operation safety. The rope end combination is made of steel plate forming welding and connecting rod welding, so the quality of the weld seam at the welding part is very important. Originally, X-ray inspection was used to detect the quality of welds. Since X-ray inspection requires a studio with special protective rays, it cannot be operated on-site. complex. Due to the above limiting factors, the use of X-ray detection brings inconvenience to mass production, let alone 100% detection. For this reason, it is usually more inclined to...
