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.Particularly relate to and reduce gap between insert and surrounding shield as far as possible, 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 beam that ray technology utilizes and the particle beams are as X ray, electronics and neutron usually realize it through the constraint of one section of cavity or conduit and transmit in the direction indicated by certain cross sectional shape with guiding, and then rely on radiation-resistant glass to meet the requirement of shelter of personal safety and equipment irradiation in other direction.Radiation-resistant glass inner space general finite when x-ray apparatus is built, after device starts, internal part is then activated, and the part that therefore conduit penetrates shielding needs to be designed to install in shielding outside with the form of insert, location and dismounting.
Usually at the corresponding wall pipe cavity structure of bunch channel position design and installation of shield, its inner insert of installing realizes line to the guiding outside shield and transmission.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 affecting bunch quality.Insert size is generally several meters and weight can reach several tons, needs, by installation utility appliance, while measurement adjustment, to complete installation operation by means of only wall pipe opening.In some cases, wall pipe insert is reset after needing detachable maintaining again simultaneously, and because environment is special, for reducing the impact of possible irradiation on workmen, dismounting and repacking operation need to complete fast as far as possible.
For the ray particle jet flow effect avoiding straight channel under radiation environment to cause, generally be designed to stepped along beam direction wall pipe, insert design size external at present and the size of wall pipe basically identical, the mode of sliding friction is adopted to install, higher to the position accuracy demand of wall pipe, operation resistance is comparatively large, directly promotes insert by auxiliary installing device, adjust, install and repeat to load and unload relative trouble, waste time and energy.So huge insert is once occur that design accuracy is inadequate simultaneously, gap is there is between insert and wall pipe, secondary is needed to fill shielding material, owing to now loading insert, remaining installing space is very narrow and small, now shielding material filling and fixing all face the problem being difficult to overcome, even can only pull down insert and again process correction, again install.This situation considerably increases cost and operation easier.
Summary of the invention
In order to reduce and solve the weak point in the installation of current wall pipe insert and surrounding shield structural design, simultaneously also in order to reduce the installation difficulty of insert and shielding, accelerate integral installation speed, reduce construction environment to the impact of operating personnel, the present invention devises a kind of quick fixation structure and fast-assembling method of brand-new wall pipe insert, can be implemented in and meet insert and shield basic tight situation, in the poor situation of wall pipe positioning precision, effectively can improve the installation of wall pipe insert and shield and repeat to tear open, dress efficiency, reduce workload, improve speed of application, ensure the positioning precision of insert own and repeatable position precision simultaneously.
