Description
Technical field
The present invention relates to accelerator art fields, and in particular to a kind of rack construction of medical computerized linear accelerator.
Background technique
Rack is the important frame structure of entire clinac, all components, counterweight, accelerating tube, tune
Device processed etc. will be installed on complete machine frame, therefore complete machine frame is important part.Complete machine frame includes rotary frame and fixed frame
Not only to guarantee the mechanical property and welding performance of material, but also all surround the same central point i.e. when rack is in 360 ° of rotations
The centers such as machinery, therefore when to be accelerator carry out radiotherapy as radiotherapy apparatus at the centers such as machinery of rack, to patient's tumour
The unique reference point that position is positioned, therefore to guarantee to realize and 360 ° of fixed points of fixed position are controlled under secure conditions
It treats.So its accuracy can be described as the most important technical indicator of accelerator complete machine.
However existing clinac is installed in all electronic components, microwave component and collimator and counterweight
After, when rack rotating part goes to 0 °, 90 °, 180 ° and 270 °, mechanical isocentric variable quantity is sometimes maximum in ± 1mm
Deviator reaches 2mm.2 tons of multiple counterweights cause big torsional forces to the upper hitch of rotating part and form slight rigidity and become
Shape, so that the centers such as the center of collimator and the rotation of rack be caused not to be overlapped generation offset.And entire weight has the first line of a couplet
It connects frame to undertake, but upper hitch is the welding inner cavity of long 1.3m wide 0.8m or so, and one end also unsealing.In causing
The rigid deformation of chamber.
Summary of the invention
It is an object of the invention to: for above-mentioned problem, the present invention provides a kind of machine of medical computerized linear accelerator
Frame structure to reduce connection rack inner cavity because both ends gravity cutting torsion influences to generate rigid deformation, while solving connection rack
To the problem of the installation space deficiency of remaining electronic component and microwave device in inner cavity.
The technical solution adopted by the invention is as follows:
A kind of rack construction of medical computerized linear accelerator including main board, is fixed at the sides of main board two sides
Plate, the hitch lower link for being fixed at gusset piece on the hitch above main board and being fixed at below main board
Plate, main board include upper main board and lower main board, and upper main board is connected with main shaft, and main shaft center is fixedly installed middle interval
Plate, intermediate bulkhead are fixedly connected with side plate by front apron.
Further, main board with a thickness of 45-55mm；Preferably 50mm.
Further, intermediate bulkhead with a thickness of 18-22mm；Preferably 20mm.
Further, the center of intermediate bulkhead is equipped with aperture.
Further, front apron with a thickness of 10-15mm, length 450-470mm, width 150-170mm；It is preferred that
Ground, front apron with a thickness of 12mm, length 460mm, width 160mm.
Further, corner block is provided on the outside of side plate.
Further, the triangle stiffening plate for reinforcing is provided between side plate and hitch second line of a couplet fishplate bar.
Further, the left and right inclined plate for reinforcing is provided between side plate and hitch second line of a couplet fishplate bar.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, inner cavity is divided into two by the present invention by setting intermediate bulkhead, and adds a front end face side welding shape again in end face
At one every four end faces, greatly reduce the deformation quantity of entire inner cavity, and also reduce so required addition in original inner cavity plus
Strengthening tendons and angle steel also increase installation space and the position of remaining part and device；
2, held between intermediate bulkhead setting within the bearing of the invention, thus greatly reduce hitch in rotary course because
Gravity changer generate change in torque and caused by rigidity deformation；
3, present invention setting setting on the outside of side plate is used for the corner block of steady brace, reduces inner cavity on certain effect and exists
Deformation under torsion when rotation；
4, the present invention triangle stiffening plate and left and right inclined plate of setting for reinforcing between side plate and hitch second line of a couplet fishplate bar,
Stable triangular structure is formed for further stabilization and reinforcement.
