Gantry frame 1 two lower vertical beam 6, two upper vertical beams 7 and a top beam 8 as shown in Fig. 2, be made of, wherein long square
The lower vertical beam 6 of shape is welded by multiple chapped pipes 9, as shown in figure 3, two handrails 10 are welded in the outside of chapped pipe 9,
Pedestal 11 and lower vertical beam upper junction plate 12 is respectively welded in the upper and lower side of chapped pipe 9；The upper vertical beam 7 of long rectangle is by multiple profile irons
Pipe 9 is welded, as shown in figure 4, welding two handrails 10 in the outside of chapped pipe 9, the upper and lower side of chapped pipe 9 welds respectively
Connect vertical beam lower connecting plate 13 and upper vertical beam upper junction plate 14；The top beam 8 of long rectangle is welded by multiple chapped pipes 9,
Top beam lower connecting plate 15 and top beam upper plate 16 is respectively welded at the top and bottom left and right ends of chapped pipe 9；In two lower vertical beams 6
Lower vertical beam upper junction plate 12 is connected with into two integrated beams with the upper vertical beam lower connecting plate 13 in upper vertical beam 7, and two upper vertical
Beam upper junction plate 14 is connected with composition gantry frame with top beam lower connecting plate 15 respectively, and two lower vertical beam pedestals 11 are fixed on
On ground, handrail 10 is ascended a height use for personnel's maintenance of equipment.Gantry frame 1 need to have enough rigidity and strong as the basis of device
Degree.Lower vertical beam 6, upper vertical beam 7 and top beam 8 to weld growth rectangle by multiple chapped pipes 9, meet to the requirement in performance.
Gantry frame 1 mainly considers the convenience loaded onto transport and group using the structure of lower vertical beam 6 and 7 two-period form of upper vertical beam.
Skid beam mechanism 2 is as shown in fig. 6, by sliding rail 17, sliding block 18, sliding beam 19, counterweight crossbeam 20, fixed pulley 21 and steel
Cord 22 forms, wherein is screwed sliding rail 17 on 9 front-back of chapped pipe in two upper vertical beams 7, fills on sliding rail 17
There is sliding block 18, the two groups of slideways in composition front and back provide the upper and lower displacement of 19 opposite piece of sliding beam；Sliding beam 19 is one different
Shape steel tube 9, as shown in fig. 7, sliding block fixed plate 23 is respectively welded on the facade of 9 both ends side of steel tubes, in steel tubes 9
Centre be welded with wobble gear connecting plate 24, be welded with hanging ring 25 respectively on the both ends of steel tubes 9；Counterweight crossbeam 20 is one
Steel tubes 9, as shown in figure 8, sliding block fixed plate 23 is respectively welded on one side elevation of both ends on steel tubes 9, in deformed steel
Pipe is welded with hanging ring 25 on 9 both ends respectively；21 two groups of a pair of fixed pulley are separately fixed at the both ends of top beam upper plate 16, and wirerope 22 is logical
Both ends are connect with the hanging ring 25 on sliding beam 19 and counterweight crossbeam 20 respectively after crossing fixed pulley 21, and sliding beam 19 and counterweight are horizontal
Sliding block fixed plate 23 on beam 20 is fixedly connected with the sliding block 18 on front and back sliding rail 17 respectively, sliding beam 19 and counterweight crossbeam 20
It can be slided one on the other on two sliding rail 17 of front and back respectively, sliding rail 17 uses linear slide rail, utilizes between sliding block 18 and sliding rail 17
Steel ball roll, make sliding block 18 on sliding rail 17 smoothly sliding and slip noise it is low.Heavy castings carry out X-ray non-destructive testing at present
Equipment is one connection sliding beam of wirerope on fixed pulley, and other end connects clump weight, and clump weight is suspended on vertical
In special-shaped tube cavity in column, because of the chapped pipe limited length of vertical beam, in this way plus clump weight is limited, cannot be with sliding
Crossbeam balances well, and clump weight slides in chapped pipe inner cavity, inevitably collides with chapped pipe internal chamber wall, produces
Raw slip noise.And the present invention is different from the counterweight mode that it is used, and is that clump weight is replaced using counterweight crossbeam 20, to keep
With the balance of sliding beam 19 in load conditions, the resistance of the sliding of sliding block 18 is alleviated, the stationarity of sliding is improved, avoids
Noise is generated using clump weight.The material that steel tubes 9 in sliding beam 19 use will guarantee that sliding beam 19 carries it
The performance indicator for enough stiffness and strength that the weight of its mechanism need to have, the material that the steel tubes 9 in counterweight crossbeam 20 use
Guarantee the balance in load conditions with sliding beam 19.
Skid beam transmission mechanism 3 is as shown in Figure 9 and Figure 10, by ball-screw 26, bearing 27, top chock 28, step
29, gear 30, servo motor seat 31, servo motor 32, sliding beam bracket 33 and feed screw nut 34 form, wherein cover and rolling
Bearing 27 in 26 two axial ends of ballscrew is respectively charged into top chock 28 and step 29, top chock 28 and step
29 are separately fixed on top beam upper plate 16 and upper vertical beam lower connecting plate 13, are fixed on ball-screw 26 vertically on gantry frame 1,
The power of 19 oscilaltion of sliding beam is provided.Servo motor 32 is fixed in servo motor seat 31, and servo motor seat 31 is fixed
On top beam upper plate 16, gear 30, two gears 30 are respectively provided on the upper shaft of ball-screw 26 and the axis of servo motor 32
It is meshed and drives the rotation of ball-screw 26 to drive the feed screw nut 34 being placed on ball-screw 26 to move up and down, lead screw spiral shell
Mother 34 is connected to one with screw and feed screw nut fixed plate 35, feed screw nut fixed plate 35 and 33 bottom of sliding beam bracket
The two copper sheathing pads 40 that can be rubbed between face equipped with contact surface, it is solid that bracket screw 36 passes through sliding beam bracket 33, feed screw nut
39 axial lock bracket screw 36 of nut 38 and split pin is used after fixed board 35 and screw plate washer 37, keeps feed screw nut 34 and sliding horizontal
There are certain intervals between beam bracket 33.Feed screw nut 34 is with respect to the fine-tuning upper and lower displacement of sliding beam bracket 33, sliding beam
Bracket 33 is fixedly connected with sliding beam 19 with bolt, and the transmission of ball-screw 26 and feed screw nut 34 provides sliding beam 19
Lifting drive.Skid beam transmission mechanism 3 is the transmission mechanism of the screw-nut driven using two sets of individual motors.Sliding beam 19
Lifting and driving feature be: use two servo motors 32 as transmission, than use a motor as transmission and meanwhile drive two silks
Comparatively thick stick screw is driven, gearing mechanism is simple, and rigging error is small.Transmission is ball-screw 26 and feed screw nut 34
With trapezoidal screw and screw, sprocket wheel and chain, synchronous pulley transmission compared with, there is high smooth and precision positioning, have concurrently simultaneously
The characteristics of low torque, high rigidity is super-silent, the long-life.Servo motor 32 is controlled by digital pulse signal, servo motor rotation essence
Accuracy is high, guarantees that the synchronism of two ball-screws 26 rotation is good.Because the position of the load carried on sliding beam 19 often becomes,
Two feed screw nuts 34 stress difference in transmission process cannot synchronize, and can produce micro-displacement deviation, can be in feed screw nut 34
It is eliminated with the specific connection type of sliding beam bracket 33.Feed screw nut 34 with respect between sliding beam bracket 33 there are
Certain interval, fills the micro-displacement deviation that two feed screw nuts 34 generate in transmission process perhaps, and servo motor 32 will be displaced inclined
Difference feedback makes turning for two servo motors 32 at digital pulse signal, the revolving speed of the controllable adjustment servo motor 32 of electrical system
Speed is synchronized by asynchronous holding, to make two feed screw nuts 34 reach synchronous within the anxious short time, is eliminated offset deviation, is watched
It takes motor and constantly finely tunes revolving speed, do not eliminate two 34 offset deviations of feed screw nut, sliding beam 19 is driven relatively to protect always
Water holding is flat, keeps lifting more steady, and the transmission of ordinary motor is then made less than this point.
C-arm mechanism 4 is as shown in figure 11, as the carrier of detection device, by transverse arm 41, ray tube cantilever 42 and receiver
