As shown in Figures 3 to 8, the straight rail device of translation unloading includes straight rail assembly P1, guide rail P2, oil cylinder P3, base P4, skip bucket J, cage guide mounting rail GA；Guide groove P11, pedestal P12, roller P13, piston rod P31, fairlead P32, bearing pin P33.
Guide rail P2 is fixed on cage guide mounting rail P6, and straight rail assembly P1 has two groups, is symmetrically arranged in the both sides of skip bucket P5, and chain synchronization action.
Straight rail assembly P1 includes pedestal P11, guide groove P12 and roller P13, and guide groove P12 is rigidly connected in inside the short transverse of pedestal P11, and roller P13 is connected to the two ends up and down outside pedestal P11 short transverse.
Guide rail P2 is supporting with roller P13, and every side has upper and lower two, and roller P13 can move back and forth along guide rail.
The length of guide groove P11 is more than the distance between homonymy two guide rail P2, and the two ends of guide groove P11 stretch out in outside the bottom surface of guide rail P2 respectively.Guide groove P11 is symmetrical structure along short transverse, thus ensures when skip bucket enters the straight rail assembly that translation unloads straight rail device from bottom, and the hook hooking bucket case can disengage with the pallet on framework, and when leaving straight rail assembly from top, hook can hook again pallet.
The base P4 that the cylinder body of oil cylinder P3 is fixed on cage guide mounting rail P6 by level arranges with the direction being perpendicular to guide groove P11, the head of piston rod P31 has fairlead P32, the outer end of fairlead P32 to be articulated with on pedestal P12 by bearing pin P33.Drive straight rail assembly P1 to move back and forth on guide rail P2 by the reciprocating motion of piston rod P31, thus change the relative position of straight rail assembly P1 and skip bucket.
The articulated position of fairlead P32 and pedestal P11 is between bottom roller.
Often organize and on the pedestal P11 of straight rail assembly P1, be at least connected with three rollers, on the contrary one, upper end, two, lower end or, to ensure the kinetic stability of pedestal.The pedestal upper and lower side of the present embodiment is separately installed with two rollers.
As an alternative, it is also possible to use and can do the cylinder of stretching motion or electric pushrod is used as power set.
In order to detect guide groove position, corresponding to being provided with position detecting device (being not drawn in figure) at the minimum and maximum stroke of straight rail assembly on guide rail.If detecting, guide groove does not run to target location, need to overhaul in time.
The operation principle that translation unloads straight rail device is as follows:
Under initial situation, the piston rod P32 of oil cylinder P3 is in retracted state, as shown in Figure 3 and Figure 5.Owing to straight rail assembly P1 is linked together by bearing pin P33 and the fairlead P32 being arranged on piston rod P32 head, therefore when piston rod P32 is in retracted state, straight rail assembly P1 is in the position away from skip bucket, the straight safety clearance having more than 150mm between rail assembly P1 and skip bucket, it is ensured that do not interfere with the properly functioning of skip bucket.
When judging the material promoted needed for skip bucket as composite ore, oil cylinder P3 action, being released by piston rod P31, owing to the pedestal 12 of straight rail assembly P1 is linked together with the fairlead 32 being arranged on piston rod P31 head by bearing pin P33, therefore piston rod P31 action is by band moving base P12 action.For being rigidly connected between pedestal P12 and guide groove P11, roller P13 is arranged on the upper and lower two ends of pedestal P12 and is on guide rail P2, therefore after piston rod P31 releases, the roller P13 being arranged on pedestal P12 rolls along guide rail P2, whole straight rail assembly P1 is pushed out to can be by the position of dustpan unloading, as shown in Figure 4 and Figure 6.
When skip bucket runs to this unloading point, the guide wheel of the guide wheel hook being loaded on skip enters P guide groove 11 smoothly, skip bucket continues the most up, hook is under the effect of guide wheel and guide groove P11, fulcrum around self, hook is disengaged with the pallet on skip bucket framework, after skip bucket arrives normal unloading point and comes to a complete stop, oil cylinder P3 continuation action, piston rod P31 is regained, and then guide groove P11 is retracted, at guide groove P11 drive, the support shaft of hook within it is regained direction along piston rod P31 and is moved, as shown in Figure 3 and Figure 5.
Support shaft drives skip to tilt, and skip bottom is opened, and starts unloading.After having unloaded, oil cylinder P3 continuation action, piston rod P31 is released, and then guide groove P11 is released, at guide groove P11 drive, the support shaft of hook within it is moved along piston rod P31 launch direction, skip is pushed out to the position under normal operating condition, as shown in Figure 4 and Figure 6.Now hook is in the state can hooked with pallet, and skip bucket is the most descending, when skip bucket i.e. will be disengaged from straight rail, hooks pallet, and skip bucket continues traveling downwardly, and enters and promotes circulation next time.
If improving material next time is still composite ore, oil cylinder P3 is failure to actuate, and piston rod P31 and guide groove P11 is in release state, when next time, skip bucket arrived this unloading point, the guide wheel of the guide wheel hook being contained on skip enters guide groove P11 smoothly, and starts discharged later action；If supplied materials next time is when being oxide ore or barren rock, oil cylinder P3 action, piston rod P31 is regained, and then straight rail assembly P1 is withdrawn into does not affects the position that skip bucket is properly functioning.
Under initial situation, the straight rail assembly of the translation straight rail of unloading being positioned at 1810m horizontal unloading point is in retracted state, does not affect the high-speed cruising of skip bucket.After gatehead sends Load Signal, the position switch near this gatehead opens monitoring skip bucket position, and skip bucket, at a high speed by the along the line gatehead that need not load, arrives near the gatehead sending Load Signal and slows down and come to a complete stop.
When down-hole sends composite ore promotion signal, skip bucket high-speed cruising is to 1244m gatehead and comes to a complete stop, skip loading device fills ore deposit to skip bucket, the translation being now placed in the unloading point of 1810m level unloads the straight rail assembly of straight rail device and stretches out, skip bucket, along pit shaft high speed uplink, carries to 1810m horizontal unloading point and comes to a complete stop, and translation unloads the straight rail assembly action of straight rail device and completes to unload ore deposit, after jettison completes, straight rail assembly is regained.
When down-hole sends oxide ore promotion signal, skip bucket high-speed cruising is to 1244m gatehead and comes to a complete stop, and skip bucket device completes to fill ore deposit to skip bucket, and the translation being now placed in the unloading point of 1810m level unloads straight rail and is in retracted state, oxide ore, along pit shaft high speed uplink, is directly proposed earth's surface by skip bucket.When down-hole sends barren rock promotion signal, skip bucket high-speed cruising is to 1584m barren rock dress ore deposit point and comes to a complete stop, skip bucket dress ore deposit device is to skip loading, and the straight rail assembly being now placed in the translation straight rail device of unloading at the unloading point of 1810m level is in retracted state, so not affecting the operation of skip bucket, barren rock, along pit shaft high speed uplink, is directly proposed earth's surface by skip bucket.
Compared to the most only setting a gatehead at 1244m, arranging gatehead at two in lifting system, allow barren rock hoisting depth reduce 330m, the height of barren rock drop shaft also significantly reduces accordingly, blocking and collapse accident rate when effectively reducing employing kaolin suspension；Save electric power 8.741% simultaneously.Lifting system arranges the way of two unloading points, allows native system and mine existing system good combination, save a large amount of construction project.
The present embodiment uses the lifting system of single skip band cage, it is also possible to using the structure of single skip band counterweight, its operation principle is ibid.
Embodiment two, the present embodiment is the double loop whorl shaft hoisting system that multiple spot loads multiple spot unloading, as shown in Figure 2.This lifting system has n gatehead, m unloading point.Hoisting container is two skip buckets.It is provided with position switch near each loading, unloading loading point, is equipped with the independent translation of two sets at each middle unloading point and unloads straight rail device P, the unloading of the most corresponding two skip buckets.Translation unloads the structure and working principle of straight rail device P with embodiment one.
Under initial situation, the straight rail assembly of the translation straight rail device of unloading being positioned at each middle unloading point is in retracted state, does not affect the high-speed cruising of skip bucket.Multiple spot loads in multiple spot unloading double loop whorl shaft hoisting system, and when bottom skip bucket is positioned at a certain gatehead full load, the empty skip bucket on top has three kinds of possible positions, the most 1. at corresponding unloading point；2. under corresponding unloading point；3. on corresponding unloading point.
When one of them gatehead sends Load Signal, be judged to 1. operating mode time, the straight rail assembly being positioned at the two set translations straight rail devices of unloading at corresponding unloading point stretches out, the empty skip bucket on top passes through the gatehead that need not load along the line along pit shaft high-speed downstream, arriving to send near the gatehead of Load Signal and slow down and come to a complete stop, skip loading device completes to empty skip loading.Now, the skip bucket that former bottom is fully loaded with is also at the unloading point of correspondence, and translation unloads the straight rail assembly action of straight rail device, makes fully loaded dustpan unloading, has unloaded rear directly rail assembly and has regained, and the empty skip bucket high-speed downstream unloaded enters next one lifting and circulates.
When one of them gatehead sends Load Signal, be judged to 2. operating mode time, the straight rail assembly being positioned at the translation straight rail device of unloading being fully loaded with skip bucket side at corresponding unloading point stretches out, empty skip bucket passes through the gatehead that need not load along the line along pit shaft high-speed downstream, and continue traveling downwardly the gatehead by sending Load Signal, after fully loaded skip bucket arrives corresponding unloading point position and comes to a complete stop, translation unloads straight rail action and makes fully loaded dustpan unloading, after having unloaded, straight rail assembly is regained, empty skip bucket is descending, it is positioned at the empty skip bucket of bottom to go upward to send near the gatehead of Load Signal and slow down and come to a complete stop, skip loading device is to this sky skip loading, loading is empty skip bucket high-speed downstream entrance next one lifting circulation after completing.
When one of them gatehead sends Load Signal, be judged to 3. operating mode time, the translation straight rail of unloading being positioned at the fully loaded skip bucket side of corresponding unloading point stretches out, fully loaded skip bucket along pit shaft high speed uplink to corresponding unloading point position and after coming to a complete stop, translation unloads straight rail action and makes fully loaded dustpan unloading, after having unloaded, directly rail assembly is regained, and empty skip bucket continues up until the empty skip bucket being positioned at bottom comes downwards to send near the gatehead of Load Signal and deceleration is come to a complete stop.Skip loading device is to this sky skip loading, and after having loaded, fully loaded skip bucket high speed uplink enters the next one and promotes circulation.
