The specific embodiment

The support of medical gantry (1) is that metal rack constitutes, and support (1) is covered with glass fibre reinforced plastics casing, and also being equipped with 4 below it can be for the castor (27) that moves.The frame column (2) of 4 metals of support (1) is a support post, is again orbit.Reciprocating mechanism is mainly formed drive mechanism by driving shaft (9), driven shaft (10), chain (9); Driving device is to be fixed on following only 30 watts the direct current generator (3) of support (1); Driving shaft (9) and three driven shafts (10) by 8 bearing blocks (19) by paired support (1) top and the left and right sides, bottom of being separately fixed at, sprocket wheel (8) or guide wheel (7) are equipped with in the both sides of driving shaft (9), driven shaft (10), two gown chains (8) one in front and one in back hang on sprocket wheel (8) and the guide wheel (7), are connected with the holder box (11) of scanning constant head (photographic head) on the chain (4).Mass (12) utilizes the dynamic balance principle design.It and probe (photographic head), holder box weight such as (11) are complementary, and holder box (11), mass (12) are fixed on left and right two chains of support (1) (4) with chain joint card (22) respectively.The copper wheel (24) that is embedded in mass (12) both sides is an orbit with the two frame columns (1) on the left of the support (1), makes mass (12) get the operation of lifting in orbit.Holder box (11) is fixed on two guide posts (21) by holder box backing plate (20), and bearing (23) is equipped with at the two ends of guide post (21).Bearing (23) is a track with two frame columns (2) inside groove on support (1) right side, holder box (11) liftable operation in orbit.

The main effect of roller shutter (15) and viewfinder (18) is to hide internal structure, does not hinder the operate as normal of probe (photographic head) again.On 4 pairs of axle sleeves (13), be socketed with the sleeve pipe (14) that 4 stainless steel tubes make, be contained in the position up and down of the forward and backward 4 frame columns of support (1) (2), make roller shutter (15) traffic direction that is overlapped on the sleeve pipe (14) and the direction of motion of probe reciprocating mechanism become the parallel of vertical angle.Roller shutter (15) go up with tabletting (16) affixed viewfinder (18), its viewfinder (18) uses two bolts (17) to be fixed on the holder box (11) again, the both sides of viewfinder (18) stud with copper pulley (25), and copper pulley (25) moves on the track of preceding two frame columns (2) inboard of support (1).Probe (photographic head) optical center is designed in the center of viewfinder (18), thereby has guaranteed probe (photographic head) and viewfinder (18) synchronization lifting.Viewfinder (18) has also designed front shroud (26), open front shroud (26) during probe (photographic head) work, front shroud when not working (26) holds the purpose that has both reached covering inside by the Magnet on viewfinder (18) top, has guaranteed probe (photographic head) operating angle up and down again.

The work process of medical gantry is: after the control circuit switch opens, direct current generator (3) rotates, and sprocket wheel on the motor shaft and chain drive the sprocket wheel (5) on the driving shaft (9).The rotation of driving shaft (9) drives sprocket wheel (6), chain (8) and 3 driven shafts (10) rotations that sprocket wheel (6) and guide wheel (7) are housed in addition thereof of both sides again.Chain (6) has driven holder box (11) motion, make probe (photographic head) lifting by thereon, roller shutter (15) and viewfinder (18) thereof have been taked rigid connection by two bolts (17) of viewfinder simultaneously, thereby realize that probe also is synchronized with the movement with the lifting of holder box (11).The frame column (2) of support (1) is gone up design travel switch, in order to limit the stroke of probe (photographic head).
