Large-sized protecting lead door assembled by lead bricks

Abstract

The invention discloses a large-sized protecting lead door assembled by lead bricks. A lead door framework is formed by welding two steel pipes; mutually plugged lead bricks are mounted between the lead bricks; two faces of the lead bricks are equipped with lining plates; composite lead strips are installed in the big steel pipes at four sides; two faces of the lead door frame are equipped with decorative panels; the left and the right sides under the lead door body are respectively equipped with two driven wheels and two active wheels; an active chain wheel is installed on the driving motor; two active wheels are respectively equipped with two driven chain wheels; the active wheel and the driven wheel are connected and placed on a heavy rail via the chain; both sides of the driving motor are equipped with tensioning wheels; the angle steel frame welded on an embedding piece of a protecting room wall is fixed with a channel steel component used as a slide way on the lead door body; the upper end of the lead door body is equipped with a fixing shaft and a rolling bearing; the rolling bearing is installed in a taper sleeve roll wheel capable of rolling in the channel steel component via a stopping ring for holes and a stopping ring for shafts. The protective lead door of the invention is convenient to assemble in field and stable in running; the problem due to ray leakage of the lead plate joint is reduced; the lead door is hard to deform.

Description

Technical field [0001] The present invention involves a protective device for non -destructive testing, which specifically says a large protective lead door for non -destructive detection protective room assembled by a tissue brick. Background technique [0002] In the non -destructive explorer industry, protective devices are an indispensable and important part. In the explorer room constructed by concrete, the lead door is the main protection point.The general lead door can be processed and then transported to the manufacturer for installation, but the large lead door is not only too heavy, the appearance is too large, there is no conditions for transportation, and it is easy to deform during transportation.If the lead plate required for protection is too thick, it is not easy to process it on the spot.Even because the lead door is too large, the exercise itinerary is too long, the opening of the lead door is difficult to be stable, and it is prone to stagnation. Invention con...

AI Technical Summary

Problems solved by technology

Ordinary jaws can be processed and then transported to the factory for installation, but large-scale jaws are not only too heavy, but also too large in size, so there is no transportation condition at all, and they are easily deformed during transportation

If the lead plate required for protection is too thick, it is not easy to process it even on site

Moreover, because the jaw is too large and the movement stroke is too long, it is difficult to open the jaw smoothly, and it is prone to jamming
