Automatic storage device for U-shaped pipes for nuclear power evaporator and control method of automatic storage device

Abstract

The invention relates to an automatic storage device for U-shaped pipes for a nuclear power evaporator and a control method of the automatic storage device. The automatic storage device for the U-shaped pipes for the nuclear power evaporator comprises material discs and an automatic control system and further comprises a material staying mechanism, a horizontal movement lifting mechanism and material storerooms. The material discs are used for placing of the U-shaped pipes. The material staying mechanism is composed of a storage material staying mechanism and a delivery material staying mechanism which are both used for parking and moving of the material discs. The horizontal movement lifting mechanism is used for moving the material discs between the material staying mechanism and the material storerooms. The material storerooms are used for storing the material discs. The automatic control system is connected with the material staying mechanism, the horizontal movement lifting mechanism and the material storerooms and controls the operation of the material staying mechanism, the horizontal movement lifting mechanism and the material storerooms. The invention further discloses the control method of the automatic storage device. According to the automatic storage device and the control method, the structure is simple, high efficiency and practicability are achieved, the space utilization rate is increased, the automation degree is improved, and labor intensity is relieved.

Description

technical field [0001] The invention relates to an automatic storage device, in particular to an automatic three-dimensional warehouse for U-shaped tubes for nuclear power evaporators, which is mainly used for automatic storage of finished 690 U-shaped tubes for nuclear power evaporators. Background technique [0002] The 690U-type tube is the core component of the steam generator in a nuclear power plant. It must have pressure resistance, high temperature resistance, corrosion resistance and good thermal conductivity. The material and manufacturing process are extremely demanding. There are many specifications of stainless steel U-shaped tubes, among which CAP1400 has 164 specifications, the outer diameter of the tube is 17.5mm, the wall thickness is 1.02mm, the radius of the bend is 82.5mm~2111.5mm, the length of straight legs is 9870mm~10225mm, and the weight of a single tube is 8.9kg~11.7kg . Faced with so many specifications of 690U-shaped tubes, its storage has become...

AI Technical Summary

Problems solved by technology

The original U-shaped tube storage is just placed on a material table, covered with canvas, U-shaped tube storage requires 6-8 people to lift and place it on the material rack at the same time, and only a dozen layers and ten layers can be placed on the material rack at most. Several specifications, a great waste of manpower and floor space

At present, there is no automatic three-dimensional warehouse with U-shaped tubes for nuclear power evaporators that can save manpower and space
