Description

A kind of quick fixation structure of radiation-proof shield through-wall pipe insert and fast-assembling method
Technical field
The present invention relates to a kind of quick fixation structure and fast-assembling method of radiation-proof shield through-wall pipe insert.Relate in particular to dwindle as far as possible insert and around shielding between gap, expect that insert can be installed rapidly simultaneously, location and dismounting.The invention belongs to structural design and the installing area of radiation safety aspect in ray technology.
Background technology
The various wave beams that ray technology utilizes and the particle beams are as X ray, electronics and neutron are conventionally realized it through the constraint of one section of cavity or conduit with guiding and are transmitted on assigned direction by certain cross sectional shape, in other direction, rely on radiation-resistant glass to meet the requirement of shelter of personal safety and equipment irradiation.Radiation-resistant glass inner space general finite when x-ray apparatus is built, after device starts, internal part is activated, so the part that conduit penetrates shielding need to be designed to install in shielding outside with the form of insert, location and dismounting.
Conventionally at the corresponding wall pipe cavity structure of bunch channel position design and installation of shield, its inner insert of installing is realized guiding and the transmission of line outside shield.Insert is as the core component in wall pipe, and its positioning precision directly affects orientation and the transmission of line, is the key index that affects bunch quality.Insert size is generally several meters and weight can reach several tons, need to be by utility appliance is installed, only by wall pipe opening, complete fitting operation measuring when adjusting.In some cases, wall pipe insert needs again to reset after detachable maintaining simultaneously, and because environment is special, for reducing the impact of possible irradiation on workmen, dismounting and refitting action need complete as far as possible fast.
For avoiding the ray particle jet flow effect that under radiation environment, straight channel causes, along beam direction wall pipe, be generally designed to stepped, at present external insert design size and the size of wall pipe are basically identical, adopt the mode of sliding friction to install, position accuracy demand to wall pipe is higher, and operation resistance is larger, by auxiliary installing device, directly promotes insert, adjust, install and repeat to load and unload relative trouble, waste time and energy.Once so huge insert occurs that design accuracy is inadequate simultaneously, between insert and wall pipe, there is gap, need secondary to fill shielding material, owing to now having packed insert into, remaining installing space is very narrow and small, the now filling of shielding material and fixing all face the problem that is difficult to overcome, even can only pull down insert and again process correction, again installs.This situation has increased cost and operation easier greatly.
Summary of the invention
For reduce and solve that current wall pipe insert is installed and shielding construction design around in weak point, simultaneously also in order to reduce the installation difficulty of insert and shielding, accelerate integral installation speed, reduce the impact of construction environment on operating personnel, the present invention has designed a kind of quick fixation structure and fast-assembling method of brand-new wall pipe insert, can realize and shield basic tight situation meeting insert, in the poor situation of wall pipe positioning precision, can effectively improve the installation of wall pipe insert and shield and repeat to tear open, dress efficiency, reduce workload, improve speed of application, guarantee the positioning precision of insert own and repeatable position precision simultaneously.
