Description
Technical field
The present invention provides the self-locking device in a kind of X ray camera chain, relates in particular to the electronic rotary self-locking device in a kind of X ray camera chain.
Background technology
In the X ray camera chain, all rotatablely moving had plenty of manually, has plenty of electronicly, but in order to increase work efficiency, what present most of producer all adopted is electronic form.And adopt electronic postrotational self-locking mode, and mostly be that following two kinds of schemes are arranged now: the one, adopt the worm and gear transmission, realize the self-locking of bulb rotation with the self-locking property of worm and gear; The 2nd, adopt electromagnetic braking, at power shaft or output shaft electromagnetic brake (generally all being the motor side power shaft) is installed partly and is realized the self-locking that rotatablely moves.
The X ray camera chain structurally has various ways, and common at home have two kinds on UC arm configuration, U arm configuration and a suspension structure, and here, we rotate to be example with the bulb in the suspension structure camera chain and describe.Suspension system structure vertical view is roughly shown in Figure 1.
Total is mainly formed by crossbeam 1, photography bed 2, detector 3, column 4, moving guide rail 5, suspension bracket main body 6, retracting cylinder 7, bulb and light concentrator assembly 8, fixed guide 9, tube stand 10 are installed.
Its mounting means does, fixed guide 9 is fixed on installs on the crossbeam 1, and moving guide rail 5 is installed on the fixed guide 9, and it can move along fixed guide 9 left and right directions.
Suspension bracket main body 6 is installed on the moving track 5, rectilinear motion before and after can doing along moving track 5; Retracting cylinder 7 is fixed on the suspension bracket main body 6; Tube stand 12 (see figure 3)s are installed in the lower end of retracting cylinder 7; Bulb and light concentrator assembly 8 (being called for short bulb 8) just are installed in the bulb anchor ear 14 of tube stand 12; Tube stand 12 can make bulb 8 around vertical axes 11 and trunnion axis 13 both directions rotation (see figure 3), and can carry out oscilaltion campaign (see figure 2) with retracting cylinder 7.Column 4 is fixed on the floor of machine room, and detector 3 is installed on it, and detector 3 can center on horizontal rotational shaft, also can do the oscilaltion campaign along column 4.Photography bed 2 be can arbitrarily move also lockable.
The whole system operation principle is: during clinostatism, patient lies on the photography bed 2, and the relative position between adjustment detector 3 and the bulb 8 makes patient's lesions position be in bulb 8 focuses and detector 3 is accepted on the vertical line at face center; In the time of upright, patient stands between detector 3 and the bulb 8, and the relative position between adjustment detector 3 and the bulb 8 makes patient's lesions position be in bulb 8 focuses and detector 3 is accepted on the vertical line at face center.Can be with reference to shown in Figure 1.The x-ray that penetrates from bulb 8 like this passes patient's lesions position and beats on the dash receiver of detector 3 after regulating the light open country, after digital processing, go up the image that generates lesions position at work station (computer), thereby the doctor can provide a diagnostic result.
Wherein, no matter be clinostatism or upright position, all require: the line that the focus of bulb 8 and detector 3 are accepted the face central point is accepted face-be that both realize centering perpendicular to detector 3.After both centerings are realized, will take measures to make both positions can self-locking, bias phenomenon appears and be unlikely to occur both centerings of machine operation stopping back.
The self-locking structure of the existing electronic rotation of bulb is seen Fig. 4;
Wherein gear reduction box 15 installs and fixes screw with motor 16 through 4 and is fixed on tube stand 12 inner chambers; Gear reduction box 15 links together through shaft coupling 17 with worm screw 18 again, makes both can realize synchronous rotation; Worm screw 18 and worm gear 19 engagements, and worm gear 19 is fixed as one with trunnion axis 13 (the electronic rotating shaft of bulb just); So when motor 16 rotated, gear reduction box 15 drove worm screw 18 through shaft coupling 17 and rotates, thereby through the worm and gear transmission bulb 8 is rotated around trunnion axis 13.
As everyone knows, through the design worm and gear parameter the time, can make it have auto-lock function, bulb 8 carries out electronic rotational time around trunnion axis 13 like this, has just had auto-lock function.
Carry out the self-locking that transmission realizes bulb 8 electronic rotations through bevel gear transmission+brake motor (being that motor has the electromagnetic brake function) in addition in addition.
The prior art shortcoming:
One, adopt the worm and gear transmission, structure takes up room greatly, and efficient is low;
Two, adopt the worm and gear transmission because worm and gear has the counter-rotating gap, long operational time anglec of rotation shift phenomenon can appear;
Three, adopt the bevel gear transmission, gear ratio is little, needs to increase the capacity of motor, and cost increases;
Four, adopt the bevel gear transmission, need the increase electromagnetic brake, cost increases.
Summary of the invention
The present invention provides the electronic rotary self-locking device in a kind of X ray camera chain, and it makes the efficient of drive mechanism big as much as possible in limited space; Anglec of rotation skew can not appear in the transmission gap of not reversing, long-play yet; Cost is low, has auto-lock function.
