Should anchor point setting location and installation hole.When carrying out the installation of pet detector module, detector module is inserted radially into limit
After the groove of position, the location and installation hole of detector module is aligned and is bolted with anchor point 323 first, to detector module
400 carry out spacing and preliminary fixation in tangential, axial direction and radially three directions, are then carrying out detector module 400 and installation
Being connected between backboard 320, in this way, not only easy for installation, installation accuracy can be also effectively ensured.
Meanwhile the also upper reserved PET cooling line installing spaces of backboard 320 are installed.
As shown in Figures 2 and 3, the major function of outer gimbal support 200 is defeated to provide the location and installation of frame housing 300, PET
Enter output cord installation, the installation of PET transitions frock, the pipeline installation of cooling system, it is illustrated that in embodiment, outer gimbal support 200 wraps
The two groups of positioning support components 220 for including a bottom supporting mechanism 210 and being fixedly mounted on bottom supporting mechanism 210.Bottom
Supporting mechanism 210 is rectangular frame structure with positioning support component 220, and it is made up of the more connections of square tube 240, meanwhile, it is
Increase structural strength, bottom supporting mechanism 210 in positioning support component 220 with being also provided with multigroup reinforcing plate.In addition, bottom branch
Support mechanism 210 also includes two groups of connecting bottom boards, and connecting bottom board is separately positioned on above two groups of adjustment bases, the square being made up of square tube
Shape frame structure level is fixed on two groups of connecting bottom boards.
As shown in figure 8, backplanes support mechanism 210 is horizontal positioned, it is fixed on two groups of sliding blocks 112, detector support frame
Frame 310 is set up in backplanes support mechanism 210, and two groups of positioning support components 220 are disposed vertically, respectively positioned at detector support frame
The both sides of frame 310, its set close to detector supporting frame 310 and with two groups of vertical outer frame members of detector supporting frame 310
Be fixedly linked, with base support coordinate realize frame housing fix with it is spacing.And hung down with two groups of detector supporting frame 310
It is straight that outer frame members 311 are set.
As shown in Figures 2 to 4, to facilitate installation, ensureing installation accuracy simultaneously, every group of positioning support component 220 is also wrapped
Positioning clamp component 230 is included, via two groups of positioning fixtures between two groups of positioning support components 220 and detector supporting frame 310
Component 230 is fixedly linked.
Two groups of positioning clamp components 230 are symmetrical arranged on the vertical center line of detector supporting frame 310, positioning fixture
The horizontal centre of component and frame housing horizontal centre are contour, and every group of positioning clamp component is arranged on frame housing and outer gimbal support
Junction, frame housing, outer gimbal support are fixedly linked via two groups of positioning clamp components to be determined for the installation of frame housing
Position.
In the present embodiment, positioning clamp component 230 includes locating support and the fixture bottom being connected with locating support clamping
Seat, two groups of locating supports respectively positioned at frame housing two vertically disposed outer frame members on, it include connection otic placode 231 and
Boss 232 is connected, the outer frame members vertical with homonymy of connection otic placode 231 are fixedly connected, and connection boss 232 is fixed on connection otic placode
On 231, and the high settings such as horizontal centre and the horizontal centre of frame housing 300 of boss 232 are connected, clamp base is arranged on left and right
