Abstract
The invention discloses automatic crawling device for magnetic particle detection of a permanent magnet wheel type steel wall surface welding seam. The automatic crawling device comprises a fixed large bottom plate, and a walking mechanism, a magnetic particle detection mechanism, a tracking mechanism and a stroke recording mechanism which are arranged on the fixed large bottom plate, the walking mechanism is driven by four walking wheels; the four walking wheels are independently provided with walking wheel direct-current gear motors, the walking wheels are permanent magnet wheels, the direct-current gear motors change the transmission direction through a reversing bevel gear set to drive the permanent magnet wheels, the magnetic powder monitoring mechanism adopts a cross magnet yoke method, and the magnetic powder monitoring mechanism is provided with four electromagnet pillars which are in a door shape; and each electromagnet pillar is provided with four walking small wheels for the magnetic powder detection mechanism to cross the welding seam, and the magnetic powder monitoring mechanism and the tracking mechanism can carry out wireless information transmission and control with the outside. According to the invention, a wireless control mode and a manual control mode are adopted, so that the detection efficiency is greatly improved, the labor intensity of workers is reduced, and the detection efficiency and the economical efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of machinery and equipment, in particular to an automatic crawling device for permanent magnetic wheel type steel wall weld magnetic particle detection. Background technique [0002] Large pressure vessels can be divided into spherical tanks and cylindrical tanks according to their shapes. Generally speaking, spherical tanks are mostly high-pressure tanks, and cylindrical tanks are mostly atmospheric tanks. The pressure vessel involved in this patent is a spherical tank. The diameter of the existing spherical tank is between 4600mm and 36300mm, the thickness of the steel plate of the spherical tank is between 6mm and 120mm, and the nominal volume is 50m 3 up to 25000m 3 Between; the spherical tank is mainly composed of a cylinder, a head, and a pillar. Since the cylinder is rolled by steel plates and welded, and the connection between the cylinder, the head, and the pillars is also completed by welding, th...
