A kind of climbing robot
Technical field
The invention belongs to robotic technology field, and in particular to a kind of climbing robot.
Background technology
Concrete construction is a kind of most commonly seen building in the world today.Due to the influence of external environment and human factor,
There are security risk for many concrete constructions, it may appear that the Disease Characters such as crack, peeling, surface honeycomb, to construction quality and make
Have a negative impact with effect and safety.In apparent disease is handled, it is sometimes desirable to increase at disease position fill out concrete slurry into
Row reinforcement is administered.
At present, the detection for concrete wall and administration way have two kinds.First method is that worker is slow by lifting rope
It is slow to decline, then carry out operation.Second method is first to set up the scaffold of climbing, and worker carries out operation by scaffold again.
First method is extremely hazardous and labor intensity is very big, and second method is of high cost, work efficiency is low, and some positions are difficult to
Reach.
Thus need to design a kind of climbing robot to replace manual work.The exploitation of climbing robot has two technical sides
Face:Adsorption technology and technology of creeping.Adsorption technology is a kind of technology instigated climbing robot not slide, tumbled.At present
The common suction type in climbing robot field have deboost formula, magnetic force adsorption type, vacuum adsorption type, based on Van der Waals force
Four type of animal bionic type.Deboost formula is although easy to control, but noise is very big, and job insecurity;Magnetic adsorption type
Reliable and stable, but restricted application is adsorbed, is only applicable to irony wall;Before animal bionic type application based on Van der Waals force
Scape is very wide, but research also prematurity at present, it is difficult to input application;Vacuum adsorption type has a larger adsorption capacity, adsorption reliability,
Shortcoming is that adsorption system is complex, and easy gas leakage.The technology of creeping is to instigate climbing robot can be on all kinds of metopes certainly
By creeping, a kind of technology of neatly crossing over blockage.The common reptile fashion in climbing robot field relies primarily on sufficient formula at present

Valve changes the alternating pumping with the flat shirt rim sucker of two hinge types of group, the flat shirt rim sucker pumping of that hinge type above
During absorption, the flat shirt rim sucker of that hinge type below unclamps at the same time, and the flat shirt rim sucker of that hinge type above unclamps
When, next group of the flat shirt rim sucker of two hinge types starts alternately to be evacuated.
It is to carry out the creep direct current generator of barrier getting over mechanism 11 of sufficient formulas by two below to control and carry out with different rotating speeds when need to turn to
The differential of band is rotated to realize;When there is obstacle on wall, direct current generator is stopped, and steering engine starts sufficient formula barrier getting over mechanism 7 and lifts
Rise it is whole carry out sufficient formula and creep barrier getting over mechanism 11, carry out sufficient formulas barrier getting over mechanism 11 of creeping for three and lift successively by obstacle, realize obstacle detouring
Climb wall.
Sufficient formula and crawler type combine, and greatly increase the efficiency of creeping of climbing robot.The flat shirt rim sucker of hinge type
Tail end ball-joint can not only make climbing robot easily pass some obstacles, and can make it different angle wall it
Between transition back and forth, this design greatly strengthen the flexibility that it creeps.
