Logic control, Analog control, motion control, process control, data processing, communication and the intelligent and safe control of pass amount.
8, protection location: the wheel shaft of driven wheel has a centrifugal ratchet device in the inside of pincerlike arm, has reliable
Unidirectional brake and stuck function.When decrease speed reaches setting value 0.5m/s, protection location can snap action, do not need
The wheel shaft of driven wheel is blocked in any control, prevents anxious pendant.
As shown in Figure 1-3, by driving wheel pressure sensor 17, auxiliary positioning wheel pressure sensor 18 to the positive pressure of electric pole
Power in real time samples pressure sensor, by programmable controller complete pole, it is manned, climb, stop, decline, withdraw
Etc. functions.Electric cylinder drives two driving motors M1, M2 and guarantees that M1 works asynchronously with M2 by feedback pulse, it is ensured that device fortune
In horizontal and stable state during row.Lifting motor driving motor M3 controls the speed climbed by feedback pulse.
As shown in Figs 1-4, electricity is opened after selecting pole-climbing mode button according to electric pole type (isometrical bar/tapered rod) before pole-climbing
Source, complete machine enter working condition, press and put arm button, and folding and unfolding arm releases expansion, and the first pincerlike arm 7-1, the second pincer arm 7-2 are in
Opening state comes to device on electric pole, prepares pole-climbing.
As illustrated in figs. 5-7, manually by ontology lean rod and apply the thrust of 20n or more, driving wheel pressure sensor 17, auxiliary
This pressure conversion is reached controller at electric signal by locating wheel pressure sensor 18, and controller, that is, exportable receipts arm is instructed to two
Electric cylinder driver, electric cylinder motor M1 and M2 start to run simultaneously, and the first electric cylinder 4-1 and the second electric cylinder 4-2 are shunk, speed
4mm/s is spent, first connecting rod mechanism 6-1, second connecting rod mechanism 6-2 is pulled, is received in the first pincerlike arm 7-1, the second pincerlike arm 7-2,
Until closing up with the first sliding folding and unfolding arm 5-1 and the second sliding folding and unfolding arm 5-2, lock tongue 24 is already inserted into travelling arm at this time, electronic
Cylinder continues to receive, and the second sliding folding and unfolding arm 5-2 gradually leaves limited block 22-2, automatically lock pin under the action of return spring 28
In place, the operation of latter two sliding folding and unfolding arm is slided by the guiding of sliding slot clamp rail 23 to the locking of automatically lock pin 21 in place for 21 lockings
It is dynamic, reach rounding state.
As seen in figs. 8-10, driving wheel 1, auxiliary positioning wheel 2, after driven wheel contacts electric pole, what symmetrical arm carried out simultaneously,
When the pressure signal value of the feedback of driving wheel pressure sensor 18 rises to preset value Fn (Fn), M1 and M2 completion out of service
Pole movement.Folding and unfolding arm button 27 and selection shift fork 29 are all latched and can not operate during climbing.
The analytical calculation of Fn value: climbing for ontology is process that driving wheel generates that upward frictional force overcomes gravity acting,
Therefore driving wheel must have normal pressure to electric pole, this pressure value is exactly Fn, if human body weight 100kg, this body weight 9kg,
Then downward total force G=mg=(100+9) × 9.8=1068.2N.Frictional force f=G=1068.2N when at the uniform velocity rising accelerates
Stage rises required frictional force f acceleration value a=0.25m/s^2
F=ma=109 (9.8+0.25)=1096N
It tables look-up to obtain friction coefficient μ=0.42 of the rubber material to cement material, friction system of the rubber material to steel material
Number μ=0.38, we might as well take the coefficient 0.38 of worst situation, because electric pole only has cement material and steel at present.Friction
The power formula f=μ Fn 2885N that then Fn=f/ μ=1096/0.38=2885N is calculated is to climb to rub needed for perfect condition
Wipe power, according to measurement and experience we need to be amplified to 3500N or more, could reliably climb.
As shown in figure 8, pole-climbing personnel fasten seat belts after sitting straight by rising button, driving wheel 1 is rotated clockwise, controller
To the starting M3 operation of lifting motor driver, when controller detects any information beyond setting in operational process, M3 is for instruction
It can stop immediately.Especially when climbing tapered rod, since bar diameter is gradually reduced, at this moment driving wheel pressure sensor 17, auxiliary
18 detected value of locating wheel pressure sensor is also reducing, and controller receives driving wheel pressure sensor 17, auxiliary positioning wheel pressure
The variation of 18 signal of sensor simultaneously carries out data processing, and the motor for controlling electric servo cylinder does corresponding operation, the first electric cylinder
4-1, the second electric cylinder 4-2 are inside contracted, so that two driven wheels be driven inwardly to tighten.Then, pole mechanism just persistently maintains
The a certain range of pressure to electric pole.Control system in real time samples pressure sensor, in this way climbing in tapered rod
The pressure satisfaction of driving wheel by adjusting the flexible variation to adapt to bar diameter of electric cylinder, can be made to climb during rising required
Frictional force.And be arranged and press stop button, so that whole system will placed in a suspend state.Scram button, so that whole equipment will be located
In off-position, both state ontologies can be all self-locking on electric pole.
As shown in figure 9, pole-climbing personnel are by decline button, driving wheel 1 rotates counterclockwise at this time, especially declines in tapered rod
When, bar diameter is gradually increased, and at this moment driving wheel pressure sensor 17,18 detected value of auxiliary positioning wheel pressure sensor are also increasing,
Controller receive driving wheel pressure sensor 17,18 signal of auxiliary positioning wheel pressure sensor variation and carry out data processing,
The motor of control electric servo cylinder does corresponding operation, and the first electric cylinder 4-1, the second electric cylinder 4-2 are pushed out, then mast machine
Structure just persistently maintains the pressure to electric pole in a certain range.Control system in real time samples pressure sensor,
It can make the pressure of driving wheel during climbing in tapered rod in this way by adjusting the flexible variation to adapt to bar diameter of electric cylinder
Frictional force needed for power meets decline.It falls rear complete machine and enters pause mode, operating personnel puts closing for arm button after getting off
Lock function just releases, and can operate and put arm button.
As shown in Figure 10, it because the rigidity of pincerlike arm is high, is calculated for convenience we assume that a driven wheel Q,
Equivalent driven wheel as the first driven wheel 3-1 and the second driven wheel 3-2.So contacted with driven wheel Q and driving wheel with electric pole
Two points just establish a vertical plane.After human body weight is pressed on seat, stress redistributes immediately, such as force analysis figure
Middle a=40cm, b=40cm, c=12cm, G-O-Q are equivalent lever, and O point is fulcrum, after being pressed in G point due to the weight of people,
Auxiliary positioning wheel 2 will have the tendency that leaving electric pole when electric cylinder stroke is constant, be subtracted according to the pressure of lever principle auxiliary positioning wheel 2
Small, driving wheel 1 pressure will increase, and at this moment control system will intervene adjustment again, and electric cylinder continues to shrink, until active wheel load
When the detection pressure value of force snesor 17 is equal to 100N ± 10N, electric cylinder stops；In this way due to driven wheel have 100N to electricity
Rod pressure, so that it may which, so that ontology is in horizontal and stable state in the process of running, auxiliary positioning wheel gently againsts electric pole fortune
Row resistance is also smaller.Driving wheel can also be controlled in the section of 3500N ± 10N, but this shape to the normal pressure Fn of electric pole
State compares power consumption, and electric cylinder is needed frequently to act, and to ensure that driving wheel has electric pole enough in the section 3500N -4500N
While frictional force is climbed, and compare power saving, therefore set the pressure limit of Fn as 4000N ± 500N, is i.e. driving wheel pressure sensing
When the detected value of device 17 is in the section 3500N -4500N, electric cylinder can be failure to actuate.In force analysis figure, body frame is one
A rigid body, it is contemplated that the perpendicularity deviation of electric pole itself, the factors such as the mistake circularity of electric pole, degree of deformation, relax auxiliary positioning
The license section for taking turns the detection pressure value of pressure sensor 18 is more conform with actual condition needs.
