Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
In order to detect height of materials in real time, the present invention provides material detecting and control methods as shown in Figure 1, wherein can
To find out, height of materials/material position is detected during weight decline, weight is promoted after detecting height of materials, in weight
Judge whether the stress of cable wire meets preset condition in lifting process, when conditions are met, declines weight.Pass through the stream
Journey can make weight move back and forth, detect height of materials in real time.Specifically, detecting steel during weight decline
The tension of rope is greater than the first preset value, then continues to stretch out cable wire；The tension for detecting cable wire is less than or equal to the first preset value, then stops
The height of the length and material bottom surface only stretching out cable wire and stretched out according to the cable wire calculates charge level height.About the first preset value
Determination, it may be considered that charge level to the supporting force of weight, be less than or equal to weight weight, such as can be weight weight
3/4.According to one embodiment of present invention, it is held suffered by the first preset value=cable wire weight+weight weight+interference coefficient-weight
Towing force.Interference coefficient can be the empirical value of a setting, depend on cable wire friction suffered in process of rising or falling
It is brought outer that power, impact force, coal dust are sticked to the environment such as increased weight, interference in air flow or operation itself on cable wire or weight
Power can rule of thumb be set.The calculating of cable wire extension elongation is it is contemplated that the circle number that reel rotates, rotates according to reel
The perimeter of circle number and reel can calculate the length of cable wire stretching.In view of the cable wire position initial relative to reel and finally
Position the reel of non-integer can may not be obtained according to the difference of angle between initial position and final position in same point
The circle number of rotation.The length that cable wire stretches out can also be obtained by metering disk.If tension during weight is promoted
Greater than the first preset value and less than the second preset value, then the weight is driven to continue to rise；If the tension is greater than or equal to
Second preset value then drives the weight to decline.Determination for the second preset value, due to having been moved off material in uphill process
Face, there is no need to consider charge level to the supporting force of weight.According to one embodiment of present invention, the second preset value=cable wire weight
+ weight weight+interference coefficient.Preferably, after weight touches charge level, it is less than or equal to the feelings of the first preset value in tension
Under condition, so that it may weight be driven to rise.During visiting material, clearance zone is successively passed through when weight is run from top to bottom (in this area
Domain material does not impact cable wire and weight), blanking impact zone (in this region material impact cable wire and weight), unstable charge level area
(weight sinks because charge level receives the influence of the impact force of weight self gravity and material), complete bearing area is (in this region
Weight position is no longer changed).Cable wire is equal to weight in the tension of clearance zone and adds cable wire weight, in the tension of blanking impact zone
Interference coefficient is added equal to weight plus cable wire weight, unstable charge level area tension is equal to cable wire weight, weight weight and interference
The sum of coefficient subtracts supporting force suffered by weight, and the tension of complete bearing area can be equal to cable wire weight (to be recognized plus interference coefficient
For in supporting force situation identical with weight weight).Due to the relationship of installation site, the range of blanking impact zone and impact force
It is of different sizes, it is also possible to there is no blanking impact zone.In the present invention, the tension of cable wire is by power, torque, torque or electric current come table
Sign.As understood by those skilled in the art, torque, torque or electric current can obtain corresponding tension by conversion.
Motor drives weight to decline by just transferring, during weight decline, when the tension that cable wire is subject to is less than or waits
When the first preset value, motor reversal drives the weight to rise；In weight uphill process, when the power that cable wire is subject to is greater than first
Preset value and when less than the second preset value, motor reversal drives weight to continue to rise, and is greater than or equal to the in the power that cable wire is subject to
In the case where two preset values, motor is changed to rotate forward to drive the weight to decline by inverting.By constantly weight being driven to rise
And decline, so as to obtain charge level height in real time.
As interchangeable embodiment, during weight rises, it is also possible to open after weight rises predetermined altitude
Begin to decline, which can obtain according to experiment, can also be set according to inlet amount and the experience of operator,
Such as the predetermined altitude can be 0.01-5 meters.Compared to the first embodiment, weight promotes predetermined height after visiting to material position
The setting of degree is so that the design and operation of spy material system are simplified, but the first embodiment is more flexible, is conducive to reality
When the variation for reflecting material position.
Fig. 2 shows the structures for visiting material formula material-height exploring system.In Fig. 2, weight 5 is suspended on one end of cable wire 4, cable wire 4
It rolls up on capstan winch 3, motor 1 can drive capstan winch 3 to rotate, and gearbox 2 can be used to adjust the speed of the rotation of capstan winch 3, pass through electricity
Machine drives weight down or up forward or reverse.Further, it is also possible to metering disk and gearbox 2 are co-axially mounted, so as to
It to calculate the rope length of stretching with metering disk, and can be the calibration point that capstan winch provides.Calibration point is provided on metering disk,
For simplicity, it can also be begun to decline after weight rises to stoichiometric point.It, can be more acurrate by stoichiometric point as reference
Ground obtains the length of cable wire stretching.Preferably, the number in motor operation predetermined time, weight raising and lowering reaches default
When value or charge level height are greater than preset height, motor reversal drives the weight to rise to container top, and by metering disk
It counts and resets.Alternatively, after container top stops the preset period, motor rotating forward drives under the weight weight again
Drop, to avoid motor from excessively continually rotating forward and overturn, conducive to the service life for extending motor.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited to above-mentioned realities
The detail in mode is applied, within the scope of the technical concept of the present invention, a variety of letters can be carried out to technical solution of the present invention
Monotropic type, these simple variants all belong to the scope of protection of the present invention.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, it can be combined in any appropriate way.In order to avoid unnecessary repetition, the present invention to it is various can
No further explanation will be given for the combination of energy.
In addition, various embodiments of the present invention can be combined randomly, as long as it is without prejudice to originally
The thought of invention, it should also be regarded as the disclosure of the present invention.
