Description

TECHNICAL FIELD

[0001] The utility model relates to pressure vessel technical field, concretely is a pressure vessel weld nondestructive testing device. BACKGROUND

[0002] Pressure vessel refers to the sealed equipment that contains gas or liquid and bears pressure. Its maximum working pressure is greater than or equal to 0.1 MPa (gauge pressure), and the product of pressure and volume is greater than or equal to 2.5 MPa·L for gas, liquefied gas and liquid whose maximum working temperature is higher than or equal to the standard boiling point.

An auxiliary support unit is arranged at the middle position of the upper surface of the base. A support plate is arranged at each of the front and rear ends of the upper surface of the base. A rotating assembly is installed on the two support plates. The device is convenient for adsorbing dust swept from the surface of the cylinder through the arrangement of the arc-shaped dust collecting hood, dust collecting box, air suction fan and dust filtering bag. The cylinder is conveniently rotated through the arrangement of the second mounting plate, bearing seat, elastic top head, first drive motor and third hydraulic cylinder.

[0004] However, the device only has one support bracket, which leads to the fact that during the detection of the pressure vessel, the detection of the pressure vessel on the support bracket must be completed first, then the pressure vessel is removed from the support bracket using a forklift or hoisting equipment, and then another pressure vessel to be detected is placed in the support bracket for continuous detection. The device cannot continue to detect the weld during the process of removing the detected pressure vessel by the operating equipment and the process of placing the new pressure vessel to be detected in the support bracket. The double factors seriously affect the detection efficiency of the pressure vessel. Therefore, a pressure vessel weld nondestructive testing device is proposed to solve the problem of poor detection efficiency of the existing weld detection equipment. UTILITY MODEL CONTENTS
