(3) windlass flaw detection
Germany namely began to check simultaneously local defect and measures the cable that the long-pending electromagnetic equipment that dwindles of metal cross section is used for checking bridge on 1970, utilize windlass to make equipment edge cable move the limit record test data, but this method equipment needed thereby is more, be not suitable for regular inspection, and checking efficiency is low, cost is high, can not satisfy long apart from the cable inspection requirement
(4) hanging basket detects, safeguards
Set up the fixed pulley suspension centre by tower top, drive dolly and manned and hanging basket coating has been carried out comprehensive examination and maintenance in the high-altitude to whole cables by the people with windlass through wire rope.This method can satisfy the current check of suspension cable to be safeguarded, and can carry out the maintenance job of PE pipe, and whole structure is better, but whole equipment is complicated, and inspection charge is huge, only is fit to the large span stayed-cable bridge.
(5) the existing climbing of part inspection apparatus
Existing part drag-line climbing somascope can be realized climbing along drag-line, but can not realize that many grades are advanced and 1 grade of freely advancing of retreating, and can not be to the accurate location of disease position.
Have all in numerous inspection methods that check result is not accurate, length consuming time, expend the shortcomings such as large.
Summary of the invention
In order to overcome the deficiency of existing stayed-cable bridge drag-line appearance inspection method, the utility model provides a kind of somascope, and this detecting device can not only whole process record the drag-line state of appearance, and can accurately locate disease and the position occur, and convenient the installation, expense is lower.
the technical scheme that its technical matters that solves the utility model adopts is: a kind of drag-line appearance inspector, it is characterized in that comprising bearing support, motor is installed on bearing support, a pair of driving wheel, pair of driven and wireless camera, be provided with identical rotation spacing between two driving wheels and between two engaged wheels, driving wheel and engaged wheel are a matched pair from drag-line to be measured both sides with described drag-line to be measured and clamp, described motor-driven driving wheel rotates, make driving wheel and engaged wheel rise or descend along described drag-line to be measured
Described drag-line appearance inspector also comprises takes turns sub-encoders, and the number of turns that wheel sub-encoders record wheel rotates navigates on the position on drag-line to be measured to determine somascope; Described wireless camera is taken the image of drag-line to be measured and is sent to host computer by wireless mode.
Specifically, described bearing support comprises upper and lower bearing support, and described driving wheel is fixed in lower supporting frame, and engaged wheel is fixed in the upper support frame, and upper and lower bearing support one end is connected through the hinge, and the other end is locked by button.
Further, the utility model also is provided with the drag-line diameter regulator, and described drag-line diameter regulator acts on engaged wheel, increase or dwindle engaged wheel with respect to the distance of driving wheel.
Described driving wheel and engaged wheel are rubber tire, in order to can increase the friction force between wheel and drag-line.
Described drag-line appearance inspector also comprises for the speed control of controlling the somascope speed of travel.
Described speed control and the described sub-encoders of taking turns are positioned in a box body, and described box body is fixed in described bearing support.
The utility model can be safely, at a high speed, accurately the drag-line outward appearance is checked and rejected region is positioned, and cost is lower.
