Embodiment Construction

[0025] The technical content and detailed description of the present invention are described as follows with the accompanying drawings:

[0026] figure 1 It is a schematic diagram of a longitudinal section of a radiation-proof door structure of the present invention. Such as figure 1 As shown, a radiation-proof door structure provided by the present invention includes: a door hanging device 1 and a door body 2. The lower end of the door hanging device 1 is connected to the upper end of the door body 2.

[0027] The door hanging device 1 includes an upper hanging frame 11, a guide rail 12, an adjustment pad 13, a fixing bolt 14 and a lower hanging frame 15. Such as figure 2 As shown, the upper end of the hanging upper frame 11 is provided with a groove 16 that cooperates with the track of the guide rail 12; the lower end of the hanging upper frame 11 is provided with a horizontally long circular hole 17. The adjustment pad 13 is provided with a hole corresponding to the horizon...

Abstract

The present invention provides a radiation protection door structure which includes: door hanging device including hanging upper frame, guide way, fixed bolt and hanging lower frame; a groove that coordinates with the guide way is set on the upper end-face of the hanging upper frame and a circular hole is set on the lower end-face; a circular hole is set on the upper end-face of the hanging lower frame; the fixed bolt locks by passing through circular hole on lower end-face of the hanging upper frame and circular hole on the upper end-face of the hanging lower frame; the door includes: van-type frame, lead layer and boron containing polyethylene layer; the inner layer of the door is boron containing polyethylene layer, outer layer is lead layer and the outside of the lead layer is covered by van-type frame. The advantages are: a great volume of steel plate material and transport, hoisting cost is saved.

Description

Technical field [0001] The invention belongs to the professional field of radiation protection, and relates to a radiation protection door structure and an installation method thereof. Background technique [0002] During the operation and use of medical linear accelerators, due to the requirements of radiation protection, they are generally placed in a closed room composed of a shielding material structure wall and ceiling. The opening of the door is generally designed with a labyrinth, so that the amount of radiation received by the door is greatly reduced. , The door body is also as small as possible, so that the design and processing of the door body can be processed in the factory and then installed on site. For the large-scale test room, the radiation intensity is large and there are many types. Generally, the radiation generating equipment needs to enter and exit the test room frequently. The selected radiation shielding material has a large proportion, so the size and wei...
