The specific embodiment
The utility model embodiment provides a kind of mine winch warning device; The structural representation of the mine winch warning device that Fig. 1 is provided for the utility model embodiment; As shown in Figure 1, this warning device specifically comprises timing signal collector 10, time meter 11, current sensor 12, current comparator 13 and annunciator 14.
A kind of common bont when mine winch is mineral mining; Can be through winch with the mineral of exploiting from exploiting main shaft hooist to ground, mine winch generally includes skip bucket and motor, and skip bucket is used to load mineral; Motor is used to the lifting skip bucket moment is provided;, and after having unloaded mineral, skip bucket is transferred to the down-hole to ground with the skip hoisting that will load mineral.
Be example with the multi-rope friction type winch below, introduce the working process of mine winch.
This mine winch in the course of the work; Rotation direction through machine shaft in the control winch drives master rotor to different direction rotations; Make the skip bucket that is connected in rope ends to different direction motions, two skip buckets (being designated as first skip bucket and second skip bucket respectively) alternately are promoted to ground or transfer to the down-hole from the down-hole.
In the winch working process; Motor output electromagnetic torque; Through this electromagnetic torque is that skip bucket provides lifting power, and the weight that the size of motor output electromagnetic torque equals to be promoted to ground-surface skip bucket deducts the poor of both weight of weight that need transfer skip bucket, and the armature input current value of motor is directly proportional with the electromagnetic torque that motor is exported; The electromagnetic torque that is to say motor output is big more, and the armature received current of motor is big more.
Generally, behind the first skip hoisting ground of loading mineral, simultaneously second skip bucket of sky is transferred to the down-hole; Open the Gate-Controlled Switch of the gate skip bucket of skip bucket then, the gate of skip bucket is opened, with the mineral complete discharge in first skip bucket; Just mineral can not be trapped in this first skip bucket; With having loaded mineral in second skip bucket, again first skip bucket is transferred to the down-hole simultaneously, with second skip hoisting to ground.
But, when first skip hoisting of loading mineral to ground, when the incomplete situation of unloading takes place; Just, when the interior remainder of this first skip bucket or most of mineral, if this moment this first skip bucket is transferred; Second skip hoisting that to load mineral simultaneously is to ground, owing in first skip bucket part mineral are arranged, the weight that the size of motor output this moment electromagnetic torque equals second skip bucket deducts the weight of first skip bucket; Be the poor of both weight; The armature input current value of motor is directly proportional with the electromagnetic torque of motor output again, therefore, compares with normal circumstances; Motor output electromagnetic torque will reduce, and the armature input current value of motor also will be less than the armature input current value of motor under the normal circumstances.
But in the winch operational process, two skip buckets normally at first through after the deceleration of a bit of time and the accelerator just entering travel at the uniform speed, in deceleration and the acceleration operation phase of two skip bucket incipient stages; The armature input current value of motor changes greatly, and after getting at the uniform velocity the stage, the armature input current value of motor will remain on a stability number; Therefore; The warning device of present embodiment, when utilizing skip bucket to travel at the uniform speed the stage, the armature input current value of motor is judged the running condition of winch.
The principle of work of this warning device is following:
, to ground, when the unloading mineral, need the gate of skip bucket is opened in the skip hoisting that will load mineral; Therefore; The timing signal collector is linked to each other with the Gate-Controlled Switch of skip bucket, when the Gate-Controlled Switch of skip bucket is opened, through the timing signal collector collection signal that picks up counting; Time meter picks up counting after receiving this signal that picks up counting; And behind Preset Time, generating acquired signal, this Preset Time is for opening to the time that skip bucket gets into the stage that travels at the uniform speed, the armature input current value that begins to gather motor then through current sensor from skip bucket; That is to say that the input current value of current sensor collection is the current value that skip bucket gets into the stage that travels at the uniform speed.
Secondly, the input current value and the predetermined current value of gathering compared,, export a warning energizing signal when this input current value during less than the predetermined current value through current comparator.When the size of this predetermined current value was normally moved according to winch, the size of the armature received current of motor confirmed, just at the skip bucket complete discharge, and when skip bucket is transferred the stage that travels at the uniform speed to the down-hole, the armature input current value of motor.And because the delay mineral are many more in the skip bucket, the armature input current value of the motor that collects is more little; Therefore, can the predetermined current value be set according to actual conditions, this predetermined current value can be less than the certain ratio of the armature input current value of motor under the normal circumstances; That is to say, when just being detained the mineral of few part in the skip bucket, little to the influence on system operation of winch; Industrial accident can not take place yet, can think that still winch normally moves, this kind situation is not processed.
If the input current value of gathering is less than the predetermined current value; Explain that incomplete discharged situation takes place skip bucket, at this moment, current comparator is exported a warning energizing signal; Annunciator generates alerting signal after receiving this warning energizing signal; With prompting staff winch the irregular operating situation takes place at this moment, just incomplete discharged situation takes place in skip bucket, so that the staff in time reminds the staff of operation winch to take corresponding counter-measure; Avoid taking place industrial accident, improve the safety of mineral mining operation.
For example,, winch is reached unloading position, again unloading if should control winch and stop to transfer skip bucket the morning that the staff finds; If that finds is slow, can notify the down-hole loading depot immediately, note the winch situation of this moment, to cause the vigilant of underground operators, avoid the generation of industrial accident.
Need to prove; Above-mentioned just is the principle of work of this warning device of example explanation with the multi-rope friction type winch; This warning device not only is applicable to the mine winch of this kind structure, and also applicable to the winch of other structures, the principle of work that needs only winch is identical with above-mentioned said principle.
