Embodiment 1
The wheel leg convolution climbing robot of multi-cavity absorption of the present invention includes following four module combined with Figure 1 and Figure 2: Gu
Due to the negative pressure adsorption module of the compositions such as first sucker 2-1 on pedestal 1 etc. and the first minipump 3-1, wheel, driving are watched
Take the wheel type movement module of the compositions such as motor and synchronous belt, the composition such as base 10, rotating seat 11, motor cabinet, sucker, vacuum pump 16
Obstacle detouring arm module, the nothing of the compositions such as battery 4, digital transmission module 6, chassis driving plate 5, arm driving plate 19, holder driving plate 20
Line traffic control module.
In negative pressure adsorption module, such as Fig. 4 sucker 2-4 is fixed on bottom plate lower part by 21 4 screws, sucker center there are
Venthole 22 runs through bottom plate.Sucker is the soft sucker of rubber material, there is certain deformation space.Minipump as shown in Figure 5
3-4 etc. is placed in bottom plate top, and vacuum pump aspirating hole passes through bottom plate by plastic hose and is connected in sucker venthole 22 equal.Work as suction
When disk and wall surface are affixed, vacuum pump startup reduces air pressure in sucker, is adsorbed on bottom plate on wall surface.Four suckers and micro vacuum
Pump works independently, and is mutually redundant.
In wheel type movement module, wheel 7-3 as shown in Figure 5 etc. is placed in pedestal two sides, and axletree passes through two one group
Bearing block is fixed on pedestal top.It is 1 small pulley 25 between two bearings.The small pulley of two ipsilateral wheels passes through synchronization
Band connection together, allows ipsilateral wheel holding to operate synchronously.The driving servo motor of driving wheel is fixed on bottom by motor cabinet
Seat upside, is connected with the axis of wheel by coupling sleeve and wheel is driven to operate.When negative pressure adsorption module starting, pedestal is close to wall
Face, four wheels press wall surface, then drive vehicle wheel rotation by driving motor.Two sides wheel can independent control, pass through two sides wheel
Same run back to carry out the movement of forward-reverse and steering.
In obstacle detouring arm module, as shown in fig. 6, pedestal top center is fixed in 10 one end of base, the other end is rotary shaft peace
On the bearing of rotating seat.The rotary shaft of motor cabinet is then mounted on the bearing of the rotating seat other end.Rotating seat both ends are each solid
A fixed obstacle detouring arm servo motor drives base and the rotation of motor cabinet relative rotation seat.A rotation is fixed in motor cabinet to watch
Motor is taken, the rotation of suction cup carrier 15 of the driving motor seat other end drives the 5th sucker 13 to rotate around motor cabinet.5th sucker 13 is logical
Plastic flexible pipe is crossed to connect with the vacuum pump 16 being fixed on rotating seat.When the 5th sucker 13 is close to wall surface, start vacuum pump 16
Suction cup interior air pressure is reduced, the 5th sucker 13 is adsorbed on wall surface under atmospheric pressure effect.
In wireless control module, battery 4, chassis driving plate 5 and digital transmission module 6 are fixed on pedestal 1, arm driving plate and
Holder driving plate is placed in inside rotating seat.Battery 4 is all control panels in robot, servo motor and vacuum pump power supply.Number
Transmission module 6 provides long-range remote control function, and chassis driving plate controls the work of 4 minipumps etc. on bottom plate, 2 wheel drivings
The work of servo motor etc. and the work of vacuum pump.Arm driving plate 19 is responsible for the control of the first rotary shaft 17, holder driving plate
20 are responsible for the control that the second rotary shaft 18 and suction cup carrier 15 rotate.
The rotating seat 11 of obstacle detouring arm, which lifts, when wall is climbed by robot raises the 5th sucker 13, and the pumpings such as minipump will inhale
The air pressure insides such as disk reduce, and sucker suction drives pedestal 1 to press to ground in wall surface, and wheel etc. is close to wall surface.Drive servo motor
The first wheel 7-1 is driven to rotate, ipsilateral third wheel 7-3 is under the first synchronous belt 9-1 effect in the synchronous rotation of the first wheel 7-1
Turn.When two sides wheel advances, entire robot is driven to advance on wall surface.When two sides wheel is rotated with differential or opposite direction
When, robot can turn on wall surface.
When robot encounters obstacle on wall surface, obstacle detouring arm falls rotating seat 11, and the 5th sucker 13 is allowed to fall in obstacle
On the wall surface at edge.Starting vacuum pump 16 will be pumped into negative-pressure adsorption in being then shut off on pedestal 1 on wall surface inside the 5th sucker 13
Minipump etc., so that robot base is detached from wall surface.Obstacle detouring arm passes through the second rotary shaft 18 for rotating seat 11 opposite first
Motor cabinet 12 lifts, the rotating servo electricity after the arrival of robot chassis can be with the height of leaping over obstacles, in first motor seat 12
Machine 14 rotates, and band mobile robot is axis rotation around first motor seat 12.When robot chassis is rotated to the obstacle other end, stop
Rotating servo motor 14 works, and obstacle detouring arm falls the wall that robot chassis is placed in the obstacle other side further around the second rotary shaft 18
On face.Chassis is adsorbed to robot chassis on metope close to unlatching minipump etc. after wall surface.The absorption of robot chassis
Vacuum pump 16 is closed after on to wall surface, obstacle detouring arm, which lifts rotating seat 11, after the 5th sucker 13 loses absorption allows sucker to be higher than
After obstacle, robot can sail out of obstacle and continue wall surface advance.
In conclusion the wheel leg convolution climbing robot of multi-cavity absorption of the present invention has absorption to stablize, movement velocity is fast,
It may span across obstacle and control simple advantage, extend the application field of climbing robot.
