Technical field
The utility model relates to the technical fields of mining industry facility, and in particular to one kind autobalance calibration and can have and tiltedly slip
The Internet of Things measure hopper of slot.
Background technique
Mining industry weighing-appliance has measure hopper, and principle is first to be packed into coal in measure hopper by Bunker, by being installed on
The weighing sensor under measure hopper is supported, weight signal is changed into electric signal, then convert through amplification, filtering, A/D, finally led to
Cross microprocessor data processing, complete weighing, and handle skip bucket in place after, by the coal-discharging to skip bucket in measure hopper,
Reach skip bucket quantitative loading.
Measure hopper is other than guaranteeing the accuracy of weighing, it is also necessary to draw off coal, smoothly to weigh next time.So
Existing measure hopper generally includes inclined chute and this scale of construction of measure hopper part.
The CN107499745A of Huaibei mining industry share discloses a kind of measure hopper of processing inside delay coal, existing in order to solve

The bar 62 that inclines presses the inner hole of limit hole 6, then tactile sensor 53 issues weighing failure signal, control mechanism to control mechanism 50
The lifting piston 25 of 50 order elevating rams 21 bounces back to limit position, from lifting state return to idle state, scale hooper 10 by
The support of elevating ram 21 becomes being supported by support leg mechanism 60.This cause tactile sensor 53 touch 6 inner hole of limit hole angle be
Weigh extreme tilt angle β.Weighing extreme tilt angle β is generally at 5 ° -10 °.
In an inclined state, automatic horizontal calibration 30 can be used as the measurement reference of horizontal lifting, match with weighing weighing apparatus 20 and cooperateing with
Same completion level lifting work is amounted to, ensure that the accuracy of weighing.Specifically comprise the following steps:
1) positioning distance measuring horizontal reference Z0, the liquid level in the water column pipe 33 of linker 31 has in an inclined state
Absolute horizon π, it is also absolutely to be located at that this, which to float on each floating laser range sensor 52 for hanging down 40 top of positioning on liquid level,
Same level benchmark Z0, and the laser that laser range sensor 52 emits is also absolute upright in horizontal plane π.
2) each supporting point is surveyed initially away from SHpi, laser injection get to 1 bottom of goods vehicle cabinet and return to obtain ranging knot
Fruit, in same level benchmark Z0And under the premise of Vertical Launch laser, the scale hooper bottom of 33 position of water column pipe is measured respectively
Initial distance SHpi, the wherein positive integer of i=1-n, n is elevating ram number, if n=4, then obtain SHP1、SHP2、SHP3With
SHP4。
3) lifting judgement calculates lifting stroke LIt lifts, successively take horizontal lifting away fromIts
Middle H is lifting range；Calculate horizontal lifting stroke LIt lifts=SHpi+HPIf judging LIt lifts≤LLimit, then enter next step；
If LIt lifts≥LLimit, then it re-execute the steps 3), removes a number, i.e.,Calculate horizontal lifting stroke LIt lifts=Hpi+HP, sentence
If disconnected LIt lifts≤LLimit, then follow the steps 4)；If LIt lifts≥LLimit, then it re-execute the steps 3), until entering next step；Such as
Fruit takesLIt lifts≥LLimit, then report an error termination；
4) lifting executes, and starts each elevating ram 11, according to respective lifting stroke LIt liftsIt executes；
5) correction is horizontal, after the completion of lifting executes, surveys each supporting point finally away from EHpi, start laser range sensor 52,
Laser injection gets to 10 bottom of scale hooper and returns to obtain distance measurement result, in same level benchmark Z0And Vertical Launch laser
Under the premise of, the bottom of 33 position of water column pipe is measured respectively finally away from EHpi, wherein the positive integer of i=1-n, n are elevating ram
Number, if n=4, then obtain EHP1、EHP2、EHP3And EHP4；Ascending sequence, is minimized, other several elevating rams are lifted
The decline of oil-lifting jar piston, and primary distance, while calculating difference δ are tested every interval time t simultaneously, until the value of delta is zero
When, that is, it is horizontal to complete correction.If all equal, correction level is completed；
6) it weighs, passes the pressure value of the pressure sensor at the top of n elevating ram back, calculate pressure summation, weighed
Pressure P, unit are N, and newton obtains net weightUnits/kg, whole bucket weight GBucket 1=GOnly+GBucket 0, wherein GBucket 0For sky
The weight of measure hopper, control mechanism 50 is by GOnly、GBucket 1It is sent into metrology by wired or wireless network, completion is unattended certainly
Dynamic Weighing.
After weighing well, driving gear 72 is rotated clockwise, and gear ring 71 and rotating cylinder 2 is driven to rotate counterclockwise and topple over until turning over
Coal cinder is unloaded after the α of angle, right rear drive gear reversion carries out down after driving gear ring 71 and rotating cylinder 2 to rotate clockwise arrival weighing positions
Primary weighing.It drives gear 72 and gear ring 71 is all gear wheel, gear fit clearance is larger, it is difficult to guarantee that shoulder 4 turns to absolutely
To horizontal position, but still need correct amount in the position.
In order to solve the technical problem of " can correct amount when unhorizontal, moreover it is possible to take into account smooth discharging ", the utility model is logical
Cross following means:
(1) linker and the floating positioning cooperative achievement ranging horizontal reference Z of abswolute level and sustained height Z that hangs down0
Atmospheric pressure all is connect at the top of the liquid level of each water column pipe of linker, so even if in an inclined state, each water column pipe
33 liquid level is in same level；Floating positioning of hanging down on the liquid level floats positioning top of hanging down due to the design of its maximum cross section
The laser beam calibration of point floats on liquid level perpendicular to the maximum cross section, the floating maximum cross section for hanging down positioning, then floats vertical oriented vertices
Laser range sensor 52 also be located at the ranging horizontal reference Z of abswolute level and sustained height0。
(2) it is based on ranging horizontal reference Z0Ranging control lifting final position, realizes and once accomplishes that abswolute level lifts.
This point is embodied in the correction horizontal steps after lifting executes, and after the completion of lifting executes, it is final to survey each supporting point
Away from EHpi, ascending sequence is minimized, other several elevating ram elevating ram pistons declines, and simultaneously when interval
Between t test primary distance, while calculating difference δ, when the value of delta is zero, that is, it is horizontal to complete correction.If all equal,
Then complete correction level.Exactly it is located at the ranging horizontal reference Z of abswolute level and sustained height0Existence foundation so that correction
Level is implemented exactly.
(3) seperated design scale hooper and inclined chute
Fission design scale hooper and inclined chute, scale hooper may be designed to rotationally symmetric body, scale hooper rotation can discharging enter tiltedly
There is material unloading function, but the presence of blowpit does not influence the center of gravity of scale hooper, facilitates being precisely weighed for scale hooper in chute.
Ranging horizontal reference Z0Based on correcting level mutually, coordinated, so that control mechanism 50 is accomplished only to need once
Lifting can accurately measure loading capacity.And scale hooper and the design of inclined chute fission, then it contributes for scale hooper rule body,
Center of gravity is located on the axis of symmetry, to help to improve the accuracy of weighing.
It is described automatic calibrated horizontal and to have the Internet of Things measure hopper of inclined chute, utilize automatic horizontal calibration to determine horizontal
