Probe clamp suitable for ultrasonic testing of baseboard of oil storage tank

Abstract

The invention relates to a probe clamp suitable for ultrasonic testing of a baseboard of an oil storage tank and belongs to the field mechanical clamp devices. The probe clamp is mainly formed by a left support base, a square rod, I-shaped sleeves, a compression spring, cylindrical rods, T-shaped blocks, a handle, a right support base, a baffle, a locking lead screw, electromagnets, a through groove, round holes, screwed holes, grooves and holes. The square rod is respectively connected with the left support base and the right support base through the screwed holes, the through groove is arranged on the square rod, and a plurality of I-shaped sleeves and T-shaped blocks are placed in the through groove. The electromagnets are respectively installed on the outer sides of the left support base and the right support base, the locking lead screw penetrates through the screwed holes of the baffle to abut against the I-shaped sleeves or the T-shaped blocks, the round holes are arranged at the bottom ends of the I-shaped sleeves, the cylindrical rods are inserted into the round holes, the grooves are arranged on the cylindrical rods, the holes are arranged at the lower ends of the cylindrical rods, and ultrasonic probes can be placed in the holes. The probe clamp suitable for ultrasonic testing of the baseboard of the oil storage tank can solve the problem that detection width of the ultrasonic probes is small and transverse distance of the probes is unadjustable, and can achieve fast and efficient detection.

Description

technical field [0001] The invention relates to a probe fixture suitable for ultrasonic detection of the bottom plate of an oil storage tank, which belongs to the field of mechanical fixture devices. Background technique [0002] Oil storage tanks are one of the important tools for oil reserves. Its main function is to store oil and ensure the continuous supply of oil. At the same time, it can stabilize the abnormal fluctuation of domestic oil prices and deal with short-term oil supply shocks. The normal operation of oil storage tanks is of great significance to the strategic oil reserves and the protection of national energy security. [0003] During the use of the oil storage tank, its bottom plate may be corroded and cracked, resulting in the leakage of crude oil. Crude oil leakage will cause loss of oil reserves, soil pollution, and great safety hazards, and in serious cases, it will pose a threat to the lives of on-site workers. Therefore, it is necessary to detect th...

Problems solved by technology

[0005] At present, the fixtures of ultrasonic probes are mostly linear, the distance between the probes is not adjustable, and the width of one measurement is limited (about 0.3m), which cannot meet the characteristics of the long measurement length (about 41m) of the bottom plate of the oil storage t
