Contribute to the internal structure of omnibearing observation anchor head like this, detect the damaged degree of drag-line exactly.
Preferably, described probe is also provided with at least one LED, described main frame is also for controlling the switch of those LED and adjusting the brightness of those LED.
Those LED can provide illumination when insufficient light, contribute to the internal structure observing anchor head, detect the damaged degree of drag-line exactly.
Preferably, the quantity of described LED is 4.
Preferably, described internal image comprises still image and/or dynamic image.
Still image can be photo, and dynamic image can be film.Described probe is just equivalent to a camera when taking still image, is just equivalent to a video camera when taking dynamic image.
Preferably, described main frame comprises a GPS (global positioning system) signal receiving device, and described gps signal receiving system is used for recording geographical position signal;
Described main frame is also for storing the internal image of described geographical location information and the shooting of described probe.
The technical program can be demarcated and be checked the position of steel for wire drawing, the internal image photographed is mapped with geographical location information, is convenient to the later stage check.
On the basis meeting this area general knowledge, above-mentioned each optimum condition, can combination in any, obtains each preferred embodiments of the utility model.
Positive progressive effect of the present utility model is:
The first, be convenient to the situation of observing in the steel for wire drawing of bridge, meet Detection results needs, be highly suitable for the dynamic imaging in small space;
The second, the detection of anchor head drag-line often lacks internal image intuitively, application of the present utility model changes the damage corrosion situation of anchor head inhaul into intuitively video image material, the efficiency of detection and accuracy are improved greatly, for subsequent maintenance engineering provides reliable foundation;
