Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1, be depicted as the structure principle chart of the reverse movement analogue means detecting for prohibited items safety check system at the bottom of car of the present invention.
As seen from the figure, whole pick-up unit comprises high-speed cruising track 100, fixed tray 200, car bed die plan support 300.
Wherein, high-speed cruising track 100 is the translational speeds by nonshared control unit control fixed tray, simulates at the bottom of measuring car to be checked the path of relative motion between prohibited items safety check system and vehicle bottom.
Fixed tray 200 is for locking the relevant detection part of prohibited items safety check system at the bottom of car, and is installed on the transfer table of high-speed cruising track 100, realizes the reverse movement of parts to be detected with respect to testing environment (as vehicle bottom).
Car bed die is intended support 300 and is simulated height at the bottom of actual car, across being placed on high-speed cruising track, on it, be provided with car bed die type, this car bed die type frame that faces down is contained in car bed die and intends on support, and its center is corresponding with the running orbit of the assembly to be tested locking on fixed tray.Coordinate thus the testing environment that builds a reverse movement with high-speed cruising track 100 and fixed tray 200.
Referring to Fig. 2, it is depicted as the mechanical composition of the reverse movement analogue means detecting for prohibited items safety check system at the bottom of car of implementing to obtain based on above-mentioned principle.
Referring to Fig. 3, it is depicted as the structural representation of pick-up unit high speed orbit in Fig. 2.
This high-speed cruising track comprises the Mechanical Moving track 101 that nonshared control unit, transfer table 102 and 10m are long, transfer table 102 is for settling image collection assembly fixed tray 200 at the bottom of car, and these transfer table 102 entirety are placed on moving track 101, and track-movable.
Moving track 101 provides guiding and mobile required driving force to transfer table 102, drives transfer table 102 to come and go mobile along the bearing of trend of track 101.
Concrete, moving track 101 arranges high tenacity belt thereon, and drives transfer table to move around along mechanical tracks direction constant speed by this high tenacity belt.This high tenacity belt is one-sided smooth, another side indentation concave-convex design, so that itself and the tight interlock of controller toothed gearing.
It controls moving track 101 controller, to control translational speed, direction and the number of times of moving track 101.
When specific implementation, the high tenacity belt in this controller control mechanical tracks drives transfer table to move around along mechanical tracks direction constant speed.
Simultaneously, in order better to control, the supporting Special speed adjusting system that arranges, this Special speed adjusting system control controller, the setting of translational speed, direction and number of times is provided to user, it provides speed adjustable extent is the speed governing operation of 0～10m/s, carrys out thus simulating vehicle Negotiation speed at the uniform velocity between 0～36km/h.
Referring to Fig. 4, it is depicted as in Fig. 2 the structural representation of fixed tray in pick-up unit.
As seen from the figure, this fixed tray 200 comprises that 201,8 of the metallic support flat boards of 400mm × 350mm can elastic and upper and lower adjustable for height geometrical clamp 202.
These 8 can be divided into four groups by elastic and upper and lower adjustable for height geometrical clamp 202, on four limits that are fixed on metallic support flat board 201 facing each other, , on every limit of metallic support flat board 201, fix two geometrical clamps 202, two geometrical clamps 202 on relative edge are symmetrical, and the stiff end of each geometrical clamp 202 is towards metallic support flat board 201, between dull and stereotyped 201 upper surfaces of the stiff end of 8 geometrical clamps 202 that arrange thus and metallic support, coordinate and form a fixed area 203 that space is adjustable, realize different structure designs, relevant the fixing with detection part of prohibited items safety check system at the bottom of the tested vechicle of differing heights and size, be distributed in the geometrical clamp 202 of surrounding, can fix assembly to be detected from four sides simultaneously, ensure fixing steadiness.
In order further to improve the fixed effect of geometrical clamp 202, two geometrical clamps 202 on every side in dull and stereotyped 201 1 opposite sides of metallic support are specifically arranged on the two ends of side, and two geometrical clamps 202 on every side in another opposite side are specifically arranged on the middle part of side.Can be fixed assembly from different azimuth thus, stability is high.
Moreover, each can specifically composition by bracing frame 202a, adjusting bracket 202b and fixed teeth 202c by elastic and upper and lower adjustable for height geometrical clamp 202, wherein bracing frame 202a is made up of orthogonal fixed head and back up pad, this bracing frame 202a is fixed on dull and stereotyped 201 upper side edges of metallic support by the fixed head on it, and make with the orthogonal back up pad of fixed head not higher than the upper surface of metallic support flat board 201, and stretch out with respect to the upper surface of metallic support flat board 201.Adjusting bracket 202b is " L " type, in its bottom level section, offer Long Circle adjustment hole along its bearing of trend, and be placed in by set screw and nut in the back up pad of bracing frame 202a, realize the elastic adjusting of adjusting bracket 202b with respect to metallic support flat board 201 by the Long Circle adjustment hole on it; The vertical section of adjusting bracket 202b equally also offers Long Circle adjustment hole along its bearing of trend, to join with fixed teeth 202c, and realizes the up-down adjustment of fixed teeth 202c.Fixed teeth 202c entirety is inverted "L" shaped, and its vertical section coordinates with the Long Circle adjustment hole on adjusting bracket 202b vertical section by adjustment screw and nut as linkage section, can the vertical section that be placed in adjusting bracket 202b of up-down adjustment on; The level section of stretching out of fixed teeth 202c, towards the upper surface of metallic support flat board 201, forms downward snap-in force for treating fixation kit.
