Top cover video inspection device

Abstract

The invention belongs to the field of machinery, and particularly relates to a top cover video inspection device. An original inspection device is hoisted and transported from equipment to a nuclear island and then hoisted out from the nuclear island, the top cover video inspection task time is long, a large amount of manpower and material resources are wasted, and efficiency is low. The device comprises a central camera fixedly mounted at the top end of an electric lifter, a side camera mounting bracket is mounted between the central camera and the electric lifter, and the bottom of the electric lifter is fixedly connected with an upgrading housing; the upgrading housing is fixedly mounted on the top surface of a vehicle body platform; and three sets of strip-shaped moving devices are evenly distributed in the vehicle body platform, and each moving device comprises an omnidirectional wheel, a speed reducer and a servo motor which are connected in sequence. The device is small in mass,easy to install, high in positioning precision and capable of moving in any direction.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a top cover video inspection device. Background technique [0002] The top cover is welded by a cylinder body and a spherical crown body, and the spherical crown body is on the cylinder body. The penetrating part of the control rod driving mechanism and the penetrating part of the temperature measuring mechanism vertically penetrate the spherical cap, and are welded together with the spherical cap on the inner wall of the spherical cap. The bottom surface of the cylinder is composed of two tables, the upper table is a flange surface, and the lower table is a sealing surface. Video inspection of the J-shaped weld at the connection between the top cover penetration and the top cover, the surfacing layer on the inner surface of the top cover, and 4 evenly distributed key slots, based on the seven-axis structural robotic arm top cover video inspection device, including machine b...

Problems solved by technology

[0003] Based on the seven-axis structural robotic arm top cover video inspection device, the base is 3000mm long, 450mm wide, 600mm high, and has a net weight of 500Kg. It is easy to be damaged by collision during transportation.

During the transfer of nuclear power plants, due to their heavy weight, only gantry cranes and 20-meter ring cranes are used for hoisting and transfer. During refueling maintenance, gantry cranes and 20-meter ring cranes are occupied by critical paths. Unless the maintenance task belongs to the critical path, there is generally no window Hoisting, so during the roof video inspection, the roof video inspection equipment will be hoisted to the roof storage room within one week of the start of the refueling overhaul, and the roof video inspection equipment will be lifted out of the storage room within 10 days before the end of the refueling overhaul Outside the nuclear island, however, the interval between hoisting out and hoisting in equipment is long, and it only takes 7 days to complete the inspection, but it takes 2 months to hoist and transport the equipment to the nuclear island, and then hoist out from the nuclear island, resulting in a video on the top cover. The inspection task takes a long time, a lot of manpower and material resources are wasted, and the efficiency is low
