Abstract
The invention discloses a scanning car and a control method thereof. The scanning car comprises a car body provided with a mobile counterweight device which can adjust the gravity center of the whole scanning car left and right, to balance the state of the scanning car at left and right. Compared with the prior scanning cars, the car body of the scanning car is provided with a mobile counterweight device capable of adjusting the gravity center position of the whole scanning car left and right, therefore, the scanning car can keep correct balance state in working or idle state, to effectively avoid tire burst or roll over and the like.
Description
Technical field
The present invention relates to a kind of scanning car and control method thereof.
Background technology
Fig. 1-2 is depicted as the structural representation of existing a kind of door frame type scanning car 1.Fig. 1 shows the synoptic diagram when this door frame type scanning car 1 is scanning detection to tested vehicle 2.As shown in Figure 1, when carrying out scanning work, the transverse arm frame 3 of scanning car 1 and perpendicular jib 4 outside (promptly to the right) trail, and form a door-shaped frame, 2 on tested vehicle from this door-shaped frame by so that detected.When vehicle 2 passed through door-shaped frame, the radiation source 6 that is provided with on scanning car body 5 one sides was promptly to tested vehicle 2 divergent-ray X, and the ray of launching passes the detector assembly that is set in transverse arm frame 3 and the perpendicular jib 4 behind the tested vehicle 2 and receives (not shown).As shown in Figure 1, scanning car 1 is when scanning, and body gravity G is in the geometry symcenter of car body 5 just, and this moment, car body 5 was under the normal attitude of left and right sides balance.But, as shown in Figure 2, when scanning car 1 quit work, when inwardly taking in transverse arm frame 3 and perpendicular jib 4 gradually, body gravity G will be offset the car body center gradually, move in left side to car body 5, cause whole locomotive body 5 knockdown to the left, be easy to damage by pressure the tire 7 in left side, even can cause overturn accident.
Summary of the invention
Therefore, the present invention be intended to propose a kind of no matter in work or when not working total energy keep the scanning car of correct statokinetic.
The invention provides a kind of scanning car, comprise car body, wherein described car body is provided with the mobile counterweight device, and this mobile counterweight device can make scanning car be in left and right sides statokinetic along the centre of gravity place that left and right directions is regulated whole scanning car.
Compare with existing scanning car, because the present invention is provided with the mobile counterweight device of centre of gravity place that can the whole scanning car of left and right adjusting on the car body of scanning car, therefore make scanning car no matter be in work or when not working total energy keep correct statokinetic, prevent effectively that blowing out from appearring in scanning car or accident such as overturning.

Embodiment
[first embodiment]
Figure 3 shows that the synoptic diagram of first embodiment of mobile counterweight device of the present invention; Figure 4 shows that the front view of first embodiment of mobile counterweight device of the present invention.As shown in Figure 3 and Figure 4, scanning car of the present invention comprises car body 5, car body 5 is provided with pair of guide rails 8, and pair of guide rails 8 is arranged on the car body 5 abreast along the left and right directions of car body 5, between pair of guide rails 8, be provided with balancing weight 9, and the two ends of balancing weight 9 cooperate with pair of guide rails 8 so that along guide rail 8 move left and right by shifting roller 10 respectively.Also be set with a hydraulic cylinder 11 on car body 5, the flexible end of the expansion link of this hydraulic cylinder 11 is connected with balancing weight 9 so that promote balancing weight 9 and moves along the car body left and right directions.
As previously mentioned, the guide rail 8 of pair of parallel layout has constituted the guide of guiding balancing weight 9 move left and right of the present invention; 11 of hydraulic cylinders have constituted the driving mechanism of driving balancing weight 9 move left and right of the present invention.Aforementioned balancing weight 9, guide and driving mechanism have then constituted mobile counterweight device of the present invention on the whole.
The principle of work of the first embodiment of the present invention is described below with reference to Fig. 1, Fig. 2 and Fig. 3.For fear of tilting of car body phenomenon shown in Figure 2 occurring, quit work at scanning car 1, inwardly (promptly left) take in gradually in transverse arm frame 3 and the perpendicular jib 4, hydraulic cylinder 11 little by little promotes balancing weight 9 to the right along guide rail 8, make body gravity G roughly be in the geometric center of car body all the time, scanning car just can remain left and right sides statokinetic like this, thus accident such as blowing out of can avoiding effectively that the whole locomotive body knockdown causes or overturning.
Particularly, for the present invention, can realize Balance Control by three kinds of distinct methods.
First kind of control mode: when the transverse arm frame 3 and the perpendicular jib 4 outside (promptly to the right) of scanning car 1 trails, form (referring to Fig. 1) behind the door-shaped frame, control balancing weight 9 outwards moves to outer extreme position (not shown), thus car body 5 attitudes and the centre of gravity place of trim scanning car 1.When the transverse arm frame 3 of scanning car 1 and perpendicular jib 4 inwardly regain put in place after, control balancing weight 9 is moved into interior extreme position (not shown), thus car body 5 attitudes and the centre of gravity place of trim scanning car 1.The advantage of this control mode is only to need at inside and outside two limit positions place two sensors to be installed, and detects the motion of controlling self-balanced upper rotary by putting in place simply.
Second kind of control mode: just in time opposite with first kind of control mode, be exactly first self-balanced upper rotary, launch jib again.During withdrawal, also be first self-balanced upper rotary, regain jib again, control mode is identical with first kind of mode, and just logical order is put upside down.
The third control mode: when transverse arm frame 3 and the perpendicular jib 4 outside (promptly to the right) at scanning car 1 stretches gradually, car body 5 centers of gravity of scanning car 1 constantly change, control balancing weight 9 also outwards moves thereupon gradually, to reach at any time, the optional position, body gesture all keeps balance, and vice versa.The advantage of the third control method is to control body gesture in real time, makes it remain balance, and its shortcoming is that the software and hardware to control requires very highly, and cost is also very high.
[second embodiment]
The second embodiment of the present invention and first embodiment are basic identical, and the travel mechanism that difference only is second embodiment is different with the travel mechanism of first embodiment.As shown in Figure 5, the travel mechanism of second embodiment constitutes by being arranged on guide hump 12 on the car body and the guide recess 13 that is arranged on the balancing weight, and described guide hump 12 is slidingly arranged in the described guide recess 13 so that guiding balancing weight 9 move left and right.
[other alternate embodiment]
Driving mechanism of the present invention is not limited to hydraulic cylinder, can also be cylinder isoline thrust unit, perhaps can also be the linear drive apparatus that is made of screw rod, connecting rod or rack-and-pinion.Because above-mentioned straight pushing device or linear drive apparatus all belong to prior art, therefore no longer describe their concrete structure in detail.
The travel mechanism of the second embodiment of the present invention also can change over by the guide recess that is arranged on the guide hump on the balancing weight and be arranged on the car body and constitute, and this reciprocal variation is obvious.
By reading this instructions, these change for a person skilled in the art, are conspicuous, are not therefore enumerating one by one.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can change that scope of the present invention is limited by claims and equivalent thereof to these embodiment.
