According to the present invention, charging elevator has been now equipped with unexpected crash safety device, and unexpected crash safety device stops that charging hopper 1 is out of control to be moved down.Thus can prevent that the damage that such as this external cord break or driving means cause because charging hopper falls when breaking down occurs on concrete batch plant.
According to the present invention, this unexpected crash safety device includes multiple anti-fall safeguard 3, and it cooperates with the cooperation of anti-fall track 4.The tracks 2 of the guide rail mechanism that anti-fall track 4 is now parallel to charging hopper is extended and is installed in this tracks by installed part 40.These anti-fall safeguards are arranged on the dolly 10 of charging hopper and are triggered when hopper downward velocity exceedes certain ultimate value startup.In the case, the friction element of stop part and anti-fall rail contact therefore brake this charging hopper.
Fig. 2 illustrates the structure of the charging elevator including unexpected crash safety device with the view along charging track.Can see the dolly 10 of charging hopper 1 at this, it is by two side members 15 and is connected to a cross-member 16 of two side members at upper area and constitutes.Additionally, be provided with multiple roller 11 in side members 15, they move in the tracks of guide rail mechanism.Being provided with directive wheel 12 on cross-member 16, this directive wheel walked around by the rope of hoist engine driving means.
The tracks 2 of this charging elevator is arranged on lateral brace, and described pillar is connected with each other by lifting lathe 14.The anti-fall track 4 of this unexpected crash safety device is kept by the unshowned installed part of Fig. 2 respectively and is positioned in tracks 2.
In the side members 15 of dolly 10, being respectively equipped with anti-fall safeguard 3 in horizontal connector 16 region, it acts on anti-fall track 4.Anti-fall safeguard 3 is triggered startup by trigger mechanism 17 the most respectively, and here, the two trigger mechanism of anti-fall safeguard is connected by rotating axle 18.
The triggering of anti-fall safeguard starts and carries out now by control cord 5, and this control cord is parallel to anti-fall track 4 or tracks 2 ground extends past a upper directive wheel 6 and a lower directive wheel 7.Side is the most only located at by control cord, because another the anti-fall safeguard at opposite side is triggered startup jointly by connecting shaft 18.
Additionally, this control cord is connected with the trigger mechanism of anti-fall safeguard 3 and moves together with charging hopper 1.Upper directive wheel 6 is constituted as limiter of speed, and it stops the motion of control cord 5 when downward velocity exceedes certain ultimate value.By the stop of control cord, the trigger mechanism 17 of anti-fall safeguard is triggered, thus anti-fall safeguard acts on anti-fall track 4 and brakes this charging hopper.
Furthermore it is possible to arrange electric contact on limiter of speed, this charging elevator is fully powered off when this unexpected crash safety device is triggered startup by this electric contact.
Fig. 3 a illustrates the charging hopper being in substantially on the position at its track midpoint.As shown in Figure 3 a and Figure 3 b shows, charging hopper 1 is hung rotationally on dolly 10, for can up in region emptied.To this end, be provided with a wheel on charging hopper 1 to 13, this is taken turns and cooperates and region introversion turns hopper 1 as a result, the filled material of charging hopper is introduced in blender 8, as shown in Figure 3 b up to coordinating with guide rail 41.Additionally, charging hopper 1 has the first opening 19, charging hopper can be loaded in lower zone by this first opening, and charging hopper 1 also has the second opening 20, and material is packed into blender 8 by the second opening.But, by being arranged on dolly 10 by anti-fall safeguard 3, its motion is unrelated relative to the rollover conditions of dolly with charging hopper, thus this charging hopper can be made to rotate without having influence on unexpected crash safety device.
Also as it is shown in figure 1, be to extend straight in guide rail 2 region up and middle section of charging hopper.And in lowermost extent, it being provided with orbital member 23, the gradient of orbital member is less than the main section of tracks.Thus one, dolly 10 travels in lower zone on bend, and here, lower track member 23 is short, thus the upper roller of dolly is stayed in the linear section of this tracks.Additionally, the side members 15 of dolly is arranged between tracks 2 and the most also can be rotated away from this track, as shown by the lower zone of Fig. 1.
Now, the details of the unexpected crash safety device of the present invention below should be described in detail in conjunction with detail view.Fig. 4 is shown in which the upper directive wheel 6 of control cord, and on this, directive wheel is constituted as limiter of speed.Directive wheel 6 charging tracks upper end by install angle bar 22 to install by the way of keeping at a certain distance away with tracks 2.Limiter of speed 6 monitors speed and then the downstream rate of monitoring charging hopper of this control cord according to centrifugal force safety condition.Control cord 5 is parallel to anti-fall track 4 and extends.
Fig. 5 illustrates the lower directive wheel 7 for control cord 5, and this lower directive wheel is arranged in the lower zone of guide rail 2 by installing angle bar 24.Additionally, directive wheel 7 is arranged in such region, in this region, the steepest orbital member 23 of guide rail mechanism accesses the linear section of tracks 2.Directive wheel 7 is bearing on a lever 25, and this lever keeps control cord 5 to tighten and also allow control cord 5 to have certain move place by pouring weight 26.
Showing in detail anti-fall safeguard 3 in figure 6, it is arranged in the side members 15 of dolly 10 in transverse connection 16 region.Additionally, this anti-fall safeguard moves along anti-fall track when moving of car.Anti-fall safeguard 3 moves on anti-fall track 4 now by roller 33.
Anti-fall safeguard 3 has trigger mechanism 17, and the control cord 5 gone in ring is arranged on this trigger mechanism with its two ends.Being arranged on trigger mechanism 17 by control cord 5 and now realized by articulated elements 34, the two ends of control cord are fixed on this articulated elements.Articulated elements 34 is installed in rotation on trigger mechanism 17 by axle 35, thus this anti-fall safeguard can be made to rotate relative to this control cord.
Trigger mechanism 17 is made up of lever, and this lever will clamp part 30 by connecting rod 29 and draw in its active position.This lever is now arranged on the axle 18 being simultaneously connected with the anti-fall safeguard of the two and can be by this axle rotating support.
If now as fault and exceeded the downward predetermined speed of this charging hopper, then speed control trigger and this control cord locked.Described trigger to start especially can the lever that move because of centrifugal force of Negotiation speed controller realize.By the locking of control cord, the trigger mechanism 17 of this anti-fall safeguard is by start, thus this anti-fall safeguard starts.
Clamp roller 30 additionally, be provided with, its be in anti-fall track unshowned with Fig. 6 clamp coordinate in and the falling of only this charging hopper stopped.To this end, this anti-fall track at the first pincers block 32 and clamps process between roller 30, clamp roller and be arranged on again between this anti-fall track and the second pincers block 31.Make to clamp roller 30 engage with this anti-fall railway clamping and for the clamping of all parts additionally, pincers block 31 tilts to extend and therefore pass through when clamping roller 30 and moving connecting rod 29 relative to anti-fall raceway surface.
In the sectional view of Fig. 7, again show the arrangement form of the braking section 37 clamping roller 30, pincers block 31,32 and anti-fall track.Now in clamped condition, the braking section 37 of anti-fall track 4 is at pincers block 32 and clamps between roller 30 clamped, clamps the roller beveled edge again with pincers block 31 and clamps.By this control cord locked, start this anti-fall safeguard accordingly, and this clamps roller and mechanically stops on anti-fall track the falling of only this charging hopper.
If eliminating descending cause out of control subsequently, then this charging hopper has only to upwards to walk about a small distance so that this anti-fall safeguard self-return.
See that anti-fall track 4 is arranged on installed part 40 the most in the figure 7.Here, the end face of the anti-fall track of T-shaped 4 is fixed with power transmission fit system by fishbolt 39 in both sides, and the edge of this end face clamped by fishbolt.Because this anti-fall track is only installed on its bearing with fishbolt, so, this anti-fall track is only moved on direction stopping when this unexpected crash safety device triggers and starts, here, move to limit this and be provided with fixed stop.Thus, the overwhelming majority of Brake Energy is passed into this tracks, and this causes protected for all components participated makees land used power dissipation.Without such arrangement, then under about 20 millimeters of theoretical braking distances of this system, the Brake Energy of the overwhelming majority proceeds to charging hopper dolly, thus results in damage.
These installed parts 40 are installed in itself by bolt on the guide rail 2 of charging elevator as shown in Figure 7.
Fig. 8 illustrates that being in the present invention of its extreme higher position feeds elevator, and on this position, charging hopper 1 is cooperated by the cooperation of wheel 13 and auxiliary guide rail 41 and tumbles.Now it can be seen that, charging hopper 1 is that this hangs in the side members 15 of dolly in bottom roller 11 region rotationally.Because anti-fall safeguard 3 is arranged on dolly 10, so, anti-fall safeguard is unrelated with the rotational motion of charging hopper 1, thus achieves the secure ratch of this charging hopper on this position also by unexpected crash safety device.
Fig. 9 illustrates the charging hopper being now arranged on middle position, and charging hopper is freely hung on dolly on this position.When dolly 10 moves downward, the control cord associated movement that is connected with this anti-fall safeguard and detouring through upper directive wheel and lower directive wheel.If now without departing from predetermined speed, then this limiter of speed rotates as normal directive wheel, and this charging elevator moves downward in the case of the not start of anti-fall safeguard.But if charging hopper exceedes predetermined downward velocity, then this control cord is locked out and itself triggers again anti-fall safeguard, and this anti-fall safeguard is stopped only this charging hopper on the anti-fall track that side sets.
Now, anti-fall track 4 is constituted with straight form, just as in tracks 2 region above it and middle section.Therefore, before anti-fall track 4 also ends at the lower ends of this tracks, especially before the lower section section that this tracks accesses with bend 23.Otherwise, it may appear that this anti-fall safeguard tilts with anti-fall track 4 at this lower zone endogenous cause of ill dolly overturning movement.Because the Bottom Runby that this charging hopper is in this region is not too large, so here, this anti-fall safeguard is the most no longer requisite.
Figure 10 illustrates the charging hopper being in its extreme lower position, and dolly 10 is placed on orbital member 23 with its bottom roller on this position and is further seated in the linear section of guide rail 2 with its upper roller.This causes the anti-fall safeguard 3 being arranged in the side members 15 of dolly to vert and part cornering maneuver.But because it has been detached from and the coordinating, so not havinging inclination of anti-fall track 4 in this region.
