In the use of the present invention,
Because the headroom between ground 1 and bridge 2 is relatively low, it is unfavorable for the IMAQ to the bottom of bridge 2, and present apparatus small volume
Ingeniously, it is easily operated, it can be walked in the environment of low clearance, realize the IMAQ to the bottom of bridge 2.
Bridge 2 is divided into the acquisition units of multiple same widths according to measuring environment, every time to one of collection
Unit is acquired, and the image collecting device 4 of the present apparatus is placed on ground 2, by wheel control handle 10 come control figure
As the advance and retrogressing of harvester 4, all operated, avoided using electronic equipment and band by the way of manual control
The inaccuracy come.
After 4 advance certain distance of image collecting device, halt, function selection knob 21 is then adjusted to vertical
The position of angular adjustment, control handle 14 is then rotated, the elevation angle of camera 7 is changed, so as to the collected downhole of bridge 2
Image, after the bottom conditions of bridge 2 that can now observe are gathered, function selection knob 21 is adjusted to level angle
The position of regulation, control handle 14 is then rotated, camera 7 is done the steering of level angle, level angle regulation and vertical angle
Degree regulation cooperates, and the image that the stop place of image collecting device 4 can be collected is all after the completion of collection, then by image
Harvester 4 moves forward, and is gathered next time.
After the completion of the IMAQ in the acquisition units, change to next acquisition units and continue to gather.
The advance of image collecting device 4 is controlled by wheel control handle 10, is connected by the first flexible axle 9 through first shaft coupling 35
Wheel 8, the rotation of wheel 8, the more convenient control to image collecting device 4 are controlled manually, and mechanically operated mode is more
Stabilization, the problems such as being not in aging circuit as electronic equipment, electrical fault after much time using.
For camera 7 in vertical rotate, first rotating function selects knob 21, by the 3rd flexible axle 20 through the band of the 3rd shaft coupling 39
Dynamic check lock lever 19 rotates, and check lock lever 19 drives lock cam 22 to rotate simultaneously so that lock cam 22 is caught in the on disk 15
In one locking slot 23 so that disk 15 is fixed with the position of chuck 16, and disk 15 does on housing 6 together with chuck 16 and glided
It is dynamic, and can not rotate, control handle 14 is now rotated, drives rotating shaft 12 to rotate through second shaft coupling 36 by the second flexible axle 13,
It can not be rotated because rotating disk 15 can only slide, so when rotating shaft 12 rotates, rotating disk 15 and chuck 16 are done up and down along rotating shaft 12
Slide, guide rod 17 slides up and down with rotating disk 15, and the end of guide rod 17 is slidably connected with head 18, when guide rod 17 moves up and down, promotes
Head 18 rotates in the upper vertical of housing 6, so as to adjust the elevation angle of camera 7.
When camera 7 horizontally rotates, first rotating function selects knob 21, is driven by the 3rd flexible axle 20 through the 3rd shaft coupling 39
Check lock lever 19 rotates, and check lock lever 19 drives lock cam 22 to rotate simultaneously so that lock cam 22 is caught in the second lock on housing 6
In tight groove 24 so that the position of chuck 16 and housing 6 is fixed, and chuck 22 no longer does the slip of vertical direction along housing 6, due to turning
Disk 15 and the clamping of chuck 16, when chuck 16 can not slide up and down, rotating disk 15 can only rotate, and can not in rotating shaft 12 on move down
It is dynamic, control handle 14 is now rotated, drives rotating shaft 12 to rotate through second shaft coupling 36 by the second flexible axle 13, because rotating disk 15 can only
Rotated in the plane of its stop, so when rotating disk 15 rotated with rotating shaft 12, and there is no displacement in vertical direction, institute
Rotated therewith with guide rod 17, drive head 18 and camera 7 to rotate together, so as to control being horizontally diverted for camera 7.
Check lock lever 19 passes through chuck 16, and the circular hole passed through for check lock lever 19, Circularhole diameter and locking are offered on card 16
19 outer maximum outside diameter of bar is identical, ensures the fixation of the center when rotating of check lock lever 19.
Check lock lever 19 is provided with symmetrical hoodle 31, is provided with neck 32 corresponding with hoodle 31 in the upper wall of base 1, works as locking
When cam 22 is caught in the first locking slot 23 or the second locking slot 24, hoodle 31 is caught in neck 32, is played the position of check lock lever 19
Fixed effect, prevent that lock cam 22 disengages during the angle of camera 7 is adjusted, cause regulation to fail, and neck 32
Depth it is identical with the radius of hoodle 31, i.e., hoodle 31 only needs to overcome the elastic force of the spring of fixed hoodle 31 i.e. when rotating
Can, in the torsion of rotating shaft 12, reduced when being delivered to outside a lot, lock cam 22 can not be made to depart from the first lock
The tight locking slot 24 of groove 23 or second, and power during direct rotation lock bar 19 can easily make lock cam 22 rotate,
So as to realize that the selection of function converts.
The outside of lock cam 22 is circular arc, and the first locking slot 23 or the second locking slot 24 are similarly circular arc, circular arc
Shape structure more facilitates cooperation and frictional force is larger, can preferably make the locking slot 23 of lock cam 22 and first or the second locking
Groove 24 coordinates.
First flexible axle 9, the second flexible axle 13 and the 3rd flexible axle 30 are Universal flexible shaft, when in use, can be according to the feelings of reality
Condition selects the flexible axle of different length, and its characteristic due to Universal flexible shaft in itself, it can wind up, be released as needed
Put, when the low clearance of the bottom of bridge 2 is deeper, image collecting device 4 is remained able to enter and is wherein acquired, very just
Just.
When camera 7 does not rotate or is mobile, due to externally threaded self-locking performance in rotating shaft 12, head 18 can holding position consolidate
It is fixed, ensure that camera 7 does not shake, it is possible to increase the picture quality collected.
The present invention has the advantages that relative to prior art：1）Using full manual operation, ensure it accurately and reliably
Property, avoids information failure caused by electronic equipment, the problems such as line fault；2）It is easy to operate, easy to use, the behaviour on controller
Explain and be easily understood, can quickly be operated；3）It is adaptable, it can be used under the bridge of any low clearance,
Low to environmental requirement, no matter more deep bridge low-lying area grooves can put in, convenient to gather image.
The present invention is changed by the connection of chuck internal locking cam and rotating disk or housing, realizes sliding up and down or turning for rotating disk
It is dynamic, the set of multi-motion is realized with a set of mechanism, greatly simplify the quantity of mechanism in equipment so that operation is more simple
Just, and whole mechanism realizes fixation by the friction between lock cam and rotating disk or housing, and later maintenance cost is low, is setting
During standby lockout failure, it is only necessary to change lock cam, saved the cost of maintenance, accelerated maintenance efficiency.
