Described cross track comprises housing, and track one is arranged in housing, by motor three drive movement movable stand be arranged on track one;
Described movable stand is provided with lower fluctuating orbit, and upper lifting track installation is on lower fluctuating orbit, and motor two is arranged between the tooth bar one of fluctuating orbit and the tooth bar two of lower fluctuating orbit for controlling the lifting of upper fluctuating orbit; Described upper fluctuating orbit is also provided with track raised line, the groove block inserted for track raised line is also installed above lower fluctuating orbit;
Described checkout gear comprises the fixed bin being fixed on fluctuating orbit top, described fixed bin is provided with the reel cage swung by motor four control, long-armedly be arranged on reel cage, described long-armed one end is provided with and controls the long-armed motor six moved around in reel cage, and the other end is provided with video camera.
Preferentially, motor two, motor four and motor six are PLC and control motor.
Based on the Bridges Detection of above-mentioned a kind of bridge detecting device, comprise the steps:
1) on bridge pier, vacuum suction cup is installed, and by exhaust tube it is vacuumized and make it be adsorbed on bridge pier, wire rope is connected between vacuum suction cup;
2) running gear is put on a steel cord, in the gap that wire rope is between assembly pulley;
3) run the lifting controlling upper fluctuating orbit by motor two, run by motor six and control the long-armed distance moved around in reel cage for regulating video camera and bridge chair, until the clear picture that video camera is passed back;
4) start to detect, make whole device walk make a video recording to bottom bridge chair in silk enterprising every trade of restricting by the motion of driven by motor assembly pulley;
5) be connected with CCTV system by video camera, testing staff checks camera photography picture by display, checks detection to bottom bridge chair;
6) constantly step 1)-5 is repeated), until bed rearrangement bridge machinery completes.
Beneficial effect of the present invention: the present invention is simple to operate, whole testing process is carried out under bridge, do not affect the traffic on bridge, do not need all can arrange warning sign and arrange full-time security official to relieve traffic congestion, and saves man power and material, be applicable to promoting the use of.
