Online anti-collision and anti-radiation device for O-shaped rack

Abstract

The invention relates to an online anti-collision and anti-radiation device for an O-shaped rack. The anti-collision and anti-radiation device comprises an anti-collision and anti-radiation steel plate, a sleeve, a *-shaped supporting beam, a diagonal supporting beam, an anti-radiation steel plate, an anti-radiation opposite opening steel plate door, a door gap anti-radiation steel plate, an upright post, a steel plate bottom plate, a cross beam, a supporting beam, a rib plate A and a rib plate B for reinforcing the sleeve and the like. The device covers the O-shaped rack by using the steel plates and joist steel, and organically combines the anti-collision and anti-radiation functions together to form a steel fortress; the steel fortress allows normal seamless steel pipes to pass smoothly and blocks the abnormal seamless steel pipes outside the anti-collision and anti-radiation device to ensure the safety of the O-shaped rack; and meanwhile, gamma rays released by the O-shaped rack in operation is shielded to ensure the safety of workers nearby the O-shaped rack.

Description

technical field [0001] The invention belongs to the technical field of metallurgical ironmaking equipment, and in particular relates to a measurement safety protection and personal safety protection device for an instrument for measuring production parameters of seamless steel pipes. Background technique [0002] At present, in order to improve the market competitiveness of seamless steel pipes, large-scale seamless steel pipe production plants use multi-function instruments to measure the wall thickness, pipe diameter and other parameters of seamless steel pipes by gamma rays, so as to realize the quality control and data recording of seamless steel pipes . Since the multi-function instrument is measured on-line by the O-shaped frame, the seamless steel pipe passes through the measuring round hole (O-shaped opening) in the center of the O-shaped frame. The O-shaped frame is often damaged when the hole is opened. The O-frames used by domestic seamless steel pipe producti...

AI Technical Summary

Problems solved by technology

Since one O-shaped frame is about 10 million yuan, it is expensive, and it will consume a lot of manpower, financial resources and time whether it is repurchasing or repairing and maintaining, which is very troublesome, and more importantly, it will also affect the normal production of seamless steel pipes. Parameter measurement, data storage, and quality control have an impact on the sales and use of seamless steel pipes, reducing the market competitiveness of seamless steel pipes

In addition, gamma rays are harmful to the health of people around the O-frame during gamma-ray measurement. Once the radiation dose exceeds the national standard dose, the Ministry of Health will impose heavy financial penalties on the production plant.

[0003] The existing seamless steel pipe manufacturers at home and abroad have not designed O-shaped frame line anti-collision and anti-radiation devices. Some steel mills only add pressure roller devices in front of the O-shaped frame to prevent large jumps of seamless steel pipes. This method It can reduce the number of times that the seamless steel pipe hits the O-shaped frame, but it cannot completely protect the production safety and radiation protection of the O-shaped frame.
