Specific embodiment
The present invention is made further to illustrate in detail, intactly with reference to embodiment and comparative example.
The guard method of the anti-improper feeding landslide described in the present embodiment is used for the anti-improper feeding landslide of reclaimer
, there is pile landslip accident for preventing bucket wheel reclaimer in guard method and device, bucket wheel reclaimer includes in material extracting operation
Cantilever type bucket-wheel reclaimer or hanging arm type bucket wheel stacker-reclaimer.
As shown in Fig. 1～2, during bucket wheel reclaimer material extracting operation, from the geometrical relationship for illustrating：L=m-n；Wherein n exists
To determine simultaneously, it is known that m is as the 103 measurement sensor datum mark of distance measuring sensor to feeding face when installing the distance measuring sensor 103
The distance of front end (i.e. point of contact in figure).
Again from the geometrical relationship for illustrating：
D=h (II)
Therefore have：
In figure：
Tangent line beelines in the horizontal direction therebetween of the L for lower layer support face and the feeding face of stockpile；
M measures the distance at the point of contact in stockpile feeding face for range sensor；
N measures the distance at the point of contact in stockpile lower layer support face for range sensor；
D is the vertical dimension between two point of contacts；
Layers apart height of the h for material extracting operation, usual d≤0.6D；
D is bucket wheel diameter；
Lower layer support face and the angle tangent plane and horizontal plane in feeding face between of the θ for stockpile.
From public formula (III), if L is too small, less than by the angle of repose of operation material, now easily landslide in stockpile to θ there is
Accident.The accurate control of L is the guarantee for ensureing not occur security incident.The guard method of the present invention and equipment can accurately certainly
Dynamic measurement L.Controller 103 is calculated L by formula, so as to whether the position that current feeding face is judged according to the value of L is suitable,
And then ensure that current layer feeding face position will not be excessively forward and generation landslide is dangerous.The concrete calculating process of guard method is as follows：
1) more than bucket wheel horizontal median axis 0.1D, one group of distance measuring sensor of each setting in the both sides away from bucket wheel 0.5m, per group
Number of sensors is at least one, and multiple sensors can be monitored to material bed simultaneously；
2) when any group of range measurement L in two sensors is less than 0, represent the sensor degradation；If two biographies
During the measurement result of sensor both greater than 0, with the smaller value of two sensor measurements as the measurement result；
3) 3 alarm distance values A are arranged according to the angle of repose of material1、A2、A3, and A1>A2>A3；And according to 3 alarming values
Corresponding alarm device, preferably display lamp are set, wherein,
Work as L>A1When, current feeding face is in home, and display lamp reminds this layer of material extracting operation move on；
Work as A1<L<A2When, near optimum position, display lamp reminds this layer of material extracting operation stop for current feeding face position
Only；
Work as A2<L<A3When, current feeding face position has been close to landslide deathtrap, and display lamp reminds this layer of material extracting operation to answer
Stop immediately；
Work as L<A3When, current feeding face position has closely caved in deathtrap, and display lamp sends warning reminding；
4) controller is automatically stopped the revolution of bucket wheel reclaimer arm support and elevating movement, stops bucket wheel reclaimer advance fortune out of shape
It is dynamic
5) this guard method is additionally provided with function of shielding, and when function of shielding is opened, this method cannot be automatically stopped bucket wheel and take
The frame revolution of material horn, elevating movement, and stop bucket wheel reclaimer advance traveling function, only with prompting and warning function.
The protection device of the guard method caved in using the anti-improper feeding of the present invention, including being arranged on 101 level of bucket wheel
More than axis 0.1D, the both sides away from bucket wheel 1m respectively arrange one group of distance measuring sensor, and every group of range sensor is at least one, water
Flat spread configuration, that is to say, that as viewed from 105 belt direction of translatory motion of arm support, bucket wheel 101 each side installs one group
Distance measuring sensor.Distance measuring sensor including but not limited to it is following any one：Laser range sensor, two dimensional laser scanning instrument, three
Dimension laser scanner, ultrasonic distance sensor, radar wave range sensor or sonar sensor.As the preferred of the present embodiment
Embodiment, as viewed from the left of bucket wheel, the both sides of bucket wheel 101 are provided with left side range sensor 102L and right side range sensor
102R。
The range information distinct feed-back that distance measuring sensor is obtained is to controller 103.Resting in peace according to different material in 103
Angle stores multigroup alarming value A1、A2、A3, wherein A3＜ L, A1＞ L and A1>A2>A3.Corresponding alarming value A1、A2、A3, grasp in driver
Make platform and be provided with many driving switch, different alarming values are selected according to material, for contrasting the detected value L of distance measuring sensor.Control
Device processed is compared with alarm setting value according to the L for currently measuring, so as to judge should currently to carry out operation or prompting, and by referring to
Show that lamp prompting driver carries out corresponding operation or automatically control carrying out stoppage protection.
In the present embodiment, shielding button on driver control console, is additionally provided with, it is maskable to automatically control stoppage protection action, but not
Display lamp prompting can be stopped and reported to the police, the operator being easy on driver control console freely control cantilever type bucket-wheel reclaimer.
Distance measuring sensor is arranged on the arm support of bucket wheel reclaimer by intelligent Supports Made.Specifically, left side range sensor
102L lower ends are provided with left range sensor intelligent Supports Made 104L connections arm support 105, and right side range sensor 102R lower ends are provided with the right side
Range sensor intelligent Supports Made 104R connects arm support 105.When the arm support of bucket wheel reclaimer carries out elevating movement, intelligent Supports Made can
Ensure that distance measuring sensor in the vertical direction keeps constant with bucket wheel rotation axiss, and the measurement direction of distance measuring sensor keeps not
Become.Intelligent Supports Made can be by (including but not limited to) frame for movement, Hydrauservo System, electric servo-drive system or pneumatic servo
In either method realize.
The type and quantity of distance measuring sensor can not can play measurement bed of material distance as limitation of the present invention
Distance-finding method and equipment are considered as the protection domain for including the application, should not be using the species of distance measuring sensor and quantity as right
The restriction of the application.
