Embodiment Construction

[0039] The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] Such as figure 1 As shown, the steam generator primary side blocking plate operation robot according to the present invention consists of three parts: a rotating part, a radially telescopic part and an end lifting part.

[0041]The steam generator primary side blocking plate operation robot adopts a typical cylindrical coordinate system design, which has the advantages of simple and compact structure, convenient operation, small volume, light weight, and easy moving and clamping. Its overall structure is divided into three parts: the rotating part, the radial expansion part and the end lifting part. The three parts cooperate with each other and coordinate the control to realize the tightening and loosening of the bolts on the blocking plate at the primary side cold and hot ports of the steam generator to prevent During an overhaul of a...

Abstract

The invention provides a vapor generator primary side baffle operation robot which is capable of completing fastening and disassembly of a vapor generator primary side baffles in a nuclear power plant. The vapor generator primary side baffle operation robot is composed of a bolt fastening mechanical arm capable of rotating at an angle of 360 degrees, a force moment feedback sensing system and a video monitoring system. Intelligent location, automatic route planning, self judging of bolt fastening torque and process real-time monitoring are achieved. The vapor generator primary side baffle operation robot is simple in designed structure, small in occupied space, convenient to operate, high in accuracy, convenient to popularize and apply, and capable of reducing working time.

Description

technical field [0001] The invention relates to the technology of preventing nuclear radiation and the robot technology for controlling the tightening of bolts, in particular to a robot for operating a primary side blocking plate of a steam generator. technical background [0002] As a safe, reliable, clean and efficient electric energy, nuclear power is the strategic focus of my country's energy development. According to the medium and long-term development plan of nuclear power promulgated by our country, the proportion of total installed capacity of nuclear power will increase from less than 2% at present to more than 5% (by 2020), and the total installed capacity will reach more than 40 million kilowatts. As of 2011, the number of nuclear power units in service in my country has reached 15, and 28 units are under construction. The scale of units under construction has reached the world's largest. [0003] With the rapid development of my country's nuclear power industry...
