A kind of damping chassis and the wheel shoe formula barrier-surpassing robot of the transformer station with damping chassis
Technical field
The present invention relates to a kind of robot, and in particular to a kind of damping chassis and the wheel shoe formula of the transformer station with damping chassis
Barrier-surpassing robot.
Background technology
Transformer station is the hinge of electric power transmission network, and the security of its equipment running status is most important, has to equipment
It is to ensure that transformer station well runs and to the important guarantee of users' power supply reliability that effect is patrolled and examined.With Power Robot skill
The development of art, robot is patrolled and examined and gradually replaces manual inspection, greatly reduces labour.Current mobile crusing robot master
Wanting structure has:Wheeled, crawler type, leg-foot formula, creeping motion type etc., wherein being most widely used with wheeled and crawler type.Wheeled tool
Have the advantages that simple structure, the speed of service be fast, efficiency high, but be typically only applicable to relatively flat and hard road environment, more
Barrier ability, on soft and muddy ground, ability to act is poor.Leg-foot formula divides creeping-type and legged again, and creeping-type is to imitate to climb
A kind of bionic movement pattern of row class insect motion, is typically in static-stability state, is suitable for discrete complex environment, but row
Walk speed typically slow, and internal structure design gets up more complicated;Legged is to imitate mammal quick walk
A kind of bionic movement pattern, non-static-stability state, control system are in when being suitable for discrete complex environment, but walking at a high speed
System and mechanical structure are extremely complex, there is presently no practical.
At present, the mobile robot in substation inspection is mainly greatly wheeled robot, speed, but environmental suitability
It is poor, it is impossible to cross kerb and can not be in the complex environment downward driving such as meadow;Another kind is the crawler-type mobile with support arm
Robot, it can utilize support arm crossing over blockage, it is also possible to be walked under the complex environments such as meadow, sandstone by crawler belt, but carry out
The drawbacks of belt robot is that under common flat cement road surface, movement is slow, inefficient.So wheel carries out combined type machine
The appearance of people solves problem above, in the wheeled normal walking of common flat pavement usage;When running into the obstacles such as kerb, use
Support arm assist people's crossing over blockage.But the wheel-pedrail robot body that presently, there are does not have shock mitigation system, internal drive mode
By sprocket wheel chain drive, sprocket wheel chain drive has unstability, so also unstable during wheel-pedrail robot is patrolled and examined
It is fixed.Plus when robot is in the poor road traveling of road conditions, robot body can produce larger vibration, therewith installed in mobile flat
Testing equipment above platform is also produced and rocked, and larger vibration damages or even have influence on detection knot to testing equipment body
Really.

Transformer station's wheel shoe formula barrier-surpassing robot specific work process with shock mitigation system is as follows:
Transformer station's wheel shoe formula barrier-surpassing robot 1 with shock mitigation system when common flat road surface 2 is normally walked, front arm
Mechanism 5 lifts with back arm mechanism 9, and by running on wheels, its walking states is as shown in Figure 12.
When the transformer station's wheel shoe formula barrier-surpassing robot with shock mitigation system runs into 3 obstacle of kerb road surface, then need to pass through
Following steps complete obstacle detouring process:Front arm mechanism 5 is lifted on the upper surface for riding over kerb road surface 3, afterwards back arm mechanism 9
Toward lower swing, the transformer station's wheel shoe formula barrier-surpassing robot with shock mitigation system is propped up proper height, then by wheeled row
Walk mechanism 6 order about with shock mitigation system transformer station wheel shoe formula barrier-surpassing robot be moved along, until the change with shock mitigation system
Power station wheel shoe formula barrier-surpassing robot trailing wheel touches the upper surface on kerb road surface 3, i.e., the transformer station's wheel with shock mitigation system is carried out
When formula barrier-surpassing robot can normally walk, front arm mechanism 5 lifts with back arm mechanism 9, and then completes obstacle detouring task.Tool
As shown in accompanying drawing 13, accompanying drawing 14, accompanying drawing 15, accompanying drawing 16, the height on the above kerb road surface 3 is higher than band to the obstacle detouring process of body
Height of the shoe formula barrier-surpassing robot damping chassis 13 apart from road surface is taken turns by the transformer station for having shock mitigation system.
It is concavo-convex when running into uneven road surface 4 when the transformer station's wheel shoe formula barrier-surpassing robot with shock mitigation system is walked
The height of the starting point of uneven road surface 4 will be less than height of the damping chassis 10 apart from road surface, can now rely on wheeled normal, due to
Wheel type traveling mechanism of the invention 6 and Caterpillar transmission mechanism 8 are both designed as belt wheel and toothed belt transmission mode, in transmission process,
Operate steadily, the chassis along with present invention design is shock-damping structure formula, so robot has when uneven road surface 4 is walked
The testing equipment 43 protected above robot of effect.When shoe formula barrier-surpassing robot is taken turns by the transformer station with shock mitigation system
When passing by uneven road surface 4, road wheel 22 first touches uneven road surface 4, afterwards Caterpillar transmission mechanism 12 with it is concavo-convex not
Flat road surface 4 is contacted, and last robot trailing wheel is contacted with uneven road surface 4, finally across uneven road surface 4.When crawler belt is passed
When motivation structure 12 is contacted with uneven road surface 4, this way of contact is rigid contact, due to Caterpillar transmission mechanism 12 and lower support
Plate 13 is fixed together, so Caterpillar transmission mechanism 12 can eliminate this firm with lower supporting plate 13 in the presence of damping 15
Property vibration, reach damping effect, due to testing equipment 43 be arranged on carrier frame 11 on, carrier frame 11 is in turn mounted at lower support
On plate 13, so when robot is across uneven road surface 4, reaching damping effect.Robot is specifically across concave-convex road surface 4
Process is as shown in accompanying drawing 17, accompanying drawing 18, accompanying drawing 19, accompanying drawing 20, accompanying drawing 21.
Although above-mentioned be described with reference to accompanying drawing to specific embodiment of the invention, not to present invention protection model
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need the various modifications made by paying creative work or deformation still within protection scope of the present invention.
