A kind of permanent-magnet chain climbing robot with elastic steel sheet
Technical field
The present invention relates to a kind of climbing robot, and in particular to a kind of permanent-magnet chain wall-climbing device with elastic steel sheet
People.
Background technology
Climbing robot is a kind of automatic machinery people that can be climbed and fulfil assignment in perpendicular walls.Wall-climbing device
People is also known as wall-surface mobile robot, because vertical walls operation exceeds the limit of people, therefore is also known as limit operation abroad
Robot.Climbing robot is mainly used in petroleum chemical enterprise and defect detecting test or spray painting processing is carried out to cylindrical big tank, or is built
Build the cleaning and spraying of thing.It is used for checking thickness measuring etc. in nuclear industry, can be also used for the industries such as fire-fighting and shipbuilding.
Water-cooling wall is the main heated portion of boiler, and it is made up of the row's of number steel pipe, is distributed in the surrounding of boiler furnace.It
Inside is the water or steam of flowing, and the external world receives the heat of the flame of boiler furnace.Tube wall be heated water-cooling wall initial design when, mesh
Be not to be heated, but in order to which cooled hearth is allowed to not by high temperature.Later, due to its good heat exchange function, by
Gradually substitution bubble wants heated portion as boiler main.Be laid in boiler furnace inwall, by many parallel transistors it is molecular evaporation by
Hot face.The effect of water-cooling wall is the radiations heat energy for absorbing burner hearth high temperature flame or flue gas, and steam or hot water are produced in pipe, and
Temperature of furnace wall is reduced, furnace wall is protected.In heavy duty boiler, furnace flame temperature is very high, and the intensity of heat radiation is very big.In boiler
There are 40~50% even more heats to be absorbed by water-cooling wall.In addition to a small number of low capacity boilers, modern water-tube boiler with
Water-cooling wall is used as topmost evaporating heating surface in boiler.
For the water-cooling wall of long-term use, because corrosion or erosion are easily caused pipe wall thickness and changed, or even in tube wall
Surface is damaged, and then produces the problem of water-cooling wall is easily leaked, accordingly, it would be desirable to there is the wall thickness of the water-cooling wall of potential safety hazard
Detected so as to eliminate safe hidden trouble, but during thickness measuring is carried out to water-cooling wall, due between water-cooling wall away from
From causing existing climbing robot due to the rigid structure of its own, it is dumb to there is motion, and can not be good
Adsorb the problem of the water-cooling wall pipeline for becoming track width swashes row detection.
The content of the invention
The invention aims to solve existing climbing robot due to the rigid structure of its own, there is motion not
Flexibly, it and can not well adsorb the problem of the water-cooling wall pipeline for becoming track width swashes row detection, and then provide a kind of
