Ultrasonic bolt stress detection device

Abstract

The invention discloses an ultrasonic bolt stress detection device which comprises a detection device base, one end of the detection device base is fixedly connected with a device handrail supporting rod, one end of the device handrail supporting rod is fixedly connected with a device transverse handrail, one end of the device transverse handrail is fixedly connected with a probe buckle fixing rod, one end of the probe buckle fixing rod is provided with a probe buckle clamping groove, one end of the probe buckle clamping groove is in buckle connection with a probe buckle convex block, and one end of the probe buckle convex block is fixedly connected with a probe buckle. According to the size and specification of a probe, the probe buckle with the appropriate specification is selected, the probe buckle convex block at one end of the probe buckle is buckled into the probe buckle clamping groove, and the probe buckle is buckled on the probe buckle fixing rod; and when the probe is not used, a probe wire penetrates through a circular opening in one end of the probe buckle, and an electromagnetic coil bin is placed on the probe buckle, so that the probe can be conveniently stored, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of stress detection, in particular to an ultrasonic bolt stress detection device. Background technique [0002] As a fixed connection structure with simple structure and convenient disassembly and assembly, bolts are widely used in large-scale infrastructure and complete sets of equipment such as wind power, bridges, and cranes. The prestress applied on it has a great influence on the performance and life of the joints. The tightening force of the bolts on the joints is different, which will cause the bolts to be too tight or too loose, which may cause the bolts to break. Therefore, in addition to the stress of the fastening bolts should meet the design requirements, the stress of all bolts on the same connection joint should be uniform. A large number of bolts will be used for fastening in the connection structure of some large devices, but if multiple groups of bolts The fastening force is different, and ...

AI Technical Summary

Problems solved by technology

The prestress applied on it has a great influence on the performance and life of the joints. The tightening force of the bolts on the joints is different, which will cause the bolts to be too tight or too loose, which may cause the bolts to break

Therefore, in addition to the stress of the fastening bolts should meet the design requirements, the stress of all bolts on the same connection joint should be uniform. A large number of bolts will be used for fastening in the connection structure of some large devices, but if multiple groups of bolts The fastening force is different, and under different stress pulls, the bolts may break, resulting in the collapse of the overall structure

[0003] Therefore, a stress detection device is needed to detect the stress of the bolt, but the existing bolt stress detection device is inconvenient to use during detection
