The specific embodiment
Fig. 1 illustrates the embodiment of charging lift, and it can be used in according in the horizontal concrete mixing plant of the present invention.This charging lift is delivered to the mixer 8 of this equipment at this moment from the unshowned band of weighing for the material of will weighing.
This charging lift has charging hopper 1, and this charging hopper can move along guide rail mechanism 2 by drive unit 9.This charging hopper is placed on the dolly 10 for this reason, and this dolly is by roller 11 guiding movement on the lateral movement track 2 of guide rail mechanism.In addition, in this embodiment, the trend of the track of this charging hopper is obliquely.In order to drive this charging hopper, be provided with hoist engine 9, the rope of hoist engine acts on dolly 10 and this dolly of energy lifting of charging hopper 1.This charging hopper upwards is pulled up to this mixer by rope by the track of stipulating for this reason.
The present invention feeds vertically transporting of lift highly at this moment for example can be between 3 meters to 15 meters, advantageously between 6 meters to 12 meters.Charging hopper gross mass under the loading condition can be between 1 ton to 20 tons, advantageously between 5 tons to 10 tons.
According to the present invention, the charging lift is equipped with unexpected crash safety device now, and crash safety device stops charging hopper 1 out of control moving down suddenly.Can prevent from thus when concrete batch plant for example this external rope fracture or drive unit occur and breaks down, falling the damage that causes because of charging hopper.
According to the present invention, this unexpected crash safety device comprises a plurality of anti-fall protectors 3, and it cooperates with anti-fall track 4 cooperations.The tracks 2 that anti-fall track 4 is parallel to the guide rail mechanism of charging hopper this moment is extended and is installed on this tracks by installed part 40.These anti-fall protectors are arranged on the dolly 10 of charging hopper and are triggered startup when the downward speed of hopper surpass certain limiting value.In the case, the friction element of stop part contacts and therefore brakes this charging hopper with anti-fall track.
Fig. 2 illustrates the structure of the charging lift that comprises unexpected crash safety device with the view along the charging track.Can see the dolly 10 of charging hopper 1 at this, it is made of the cross-member 16 that two side members 15 and the upper area that is connected are connecting two side members.In addition, be provided with a plurality of rollers 11 in side members 15, they are mobile in the tracks of guide rail mechanism.Be provided with directive wheel 12 at cross-member 16, the rope of hoist engine drive unit is walked around this directive wheel.
The tracks 2 of this charging lift is installed on the lateral brace, and described pillar interconnects by lifting lathe 14.The anti-fall track 4 of this unexpected crash safety device is held to be positioned on tracks 2 by the unshowned installed part of Fig. 2 respectively.
On the side members 15 of dolly 10, in horizontal connector 16 zones, be respectively equipped with anti-fall protector 3, it acts on anti-fall track 4.Anti-fall protector triggers startup by trigger mechanism 17 respectively 3 this moments, and here, two trigger mechanisms of this of anti-fall protector link to each other by rotating axle 18.
The triggering of anti-fall protector starts to be undertaken by control cord 5 this moment, and this control cord is parallel to anti-fall track 4 or tracks 2 ground extend past a upper directive wheel 6 and a lower directive wheel 7.Control cord only is located at a side in this embodiment, because started by common the triggering by connecting shaft 18 at another anti-fall protector of opposite side.
In addition, this control cord is connected with the trigger mechanism of anti-fall protector 3 and along with charging hopper 1 motion.Upper directive wheel 6 consists of as limiter of speed, and it stops the motion of control cord 5 downwards when speed surpasses certain limiting value.By the stop of control cord, the trigger mechanism 17 of anti-fall protector is triggered, thereby anti-fall protector acts on anti-fall track 4 and brakes this charging hopper.
In addition, can electric contact be set at limiter of speed, this charging lift is triggered at this unexpected crash safety device by this electric contact and is cut off the power supply fully when starting.
Fig. 3 a illustrates the locational charging hopper that is in roughly at its track mid point.Shown in Fig. 3 a and Fig. 3 b, charging hopper 1 is hung rotationally on dolly 10, and being used for can be regional interior emptied up.For this reason, be provided with a wheel to 13 at charging hopper 1, this take turns to guide rail 41 cooperate cooperate and up regional introversion turn hopper 1, the result, material that charging hopper fills is introduced in the mixer 8, shown in Fig. 3 b.In addition, charging hopper 1 has the first opening 19, and 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 mixer 8 by the second opening.But by anti-fall protector 3 is arranged on the dolly 10, its motion is irrelevant with respect to the rollover conditions of dolly with charging hopper, thereby this charging hopper is rotated and can not have influence on unexpected crash safety device.
Also as shown in Figure 1, the guide rail 2 that is used for charging hopper is straight extension up in zone and the middle section.And in lowermost extent, being provided with orbital member 23, the gradient of orbital member is less than the main section of tracks.Thus one, dolly 10 travels at bend in lower zone, and here, lower railway spare 23 is short, thereby the upper roller of dolly is stayed in the linear section of this tracks.In addition, the side members 15 of dolly is arranged between the tracks 2 and therefore also can be rotated away from this track, as shown in the lower zone of Fig. 1.
Now, below should describe in conjunction with detail view the details of the unexpected crash safety device of the present invention in detail.Fig. 4 is at the upper directive wheel 6 of control cord this illustrate, and directive wheel consists of as limiter of speed on this.Directive wheel 6 is installed in the mode that keeps at a certain distance away with tracks 2 by angle bar 22 is installed in the upper end of charging tracks.Limiter of speed 6 according to the centrifugal force safety condition monitor this control cord speed and and then the monitoring charging hopper downstream rate.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 time directive wheel is arranged in the lower zone of guide rail 2 by angle bar 24 is installed.In addition, directive wheel 7 is arranged in such zone, in this zone, and the linear section of the not too steep orbital member 23 access tracks 2 of guide rail mechanism.Directive wheel 7 is bearing on the lever 25, and this lever tightens and allow control cord 5 that certain move place is arranged by pouring weight 26 retentive control ropes 5.
Show in detail anti-fall protector 3 in Fig. 6, it is arranged on the side members 15 of dolly 10 in transverse connection 16 zones.In addition, this anti-fall protector when moving of car along anti-fall rail moving.Anti-fall protector moves at anti-fall track 4 by roller 33 for 3 this moments.
If surpassed now the downward predetermined speed of this charging hopper because of fault, then speed control triggers and locked this control cord.But described triggering starts the lever that moves because of centrifugal force of Negotiation speed controller especially to be realized.By the locking of control cord, the trigger mechanism 17 of this anti-fall protector is by start, thereby this anti-fall protector starts.
In addition, be provided with the tight roller 30 of pincers, it is in the pincers tight fit with the unshowned anti-fall track of Fig. 6 and only the falling of this charging hopper of stopping.For this reason, this anti-fall track is at the first pincers piece 32 and clamp process between the tight roller 30, clamps tight roller and is arranged on again between this anti-fall track and the second pincers piece 31.In addition, pincers piece 31 tilts to extend with respect to anti-fall raceway surface and therefore makes the tight roller 30 of pincers engage and be used for the clamping of all parts with this anti-fall railway clamping by connecting rod 29 when tight roller 30 motion of pincers.
Again there is shown the tight roller 30 of pincers, pincers piece 31,32 and the arrangement form of the braking section 37 of anti-fall track at analysing and observe of Fig. 7.This moment, the braking section 37 of anti-fall track 4 was at pincers piece 32 and clamp between the tight roller 30 clampedly in clamped condition, and the beveled edge pincers with pincers piece 31 are tight again to clamp tight roller.By locked this control cord, accordingly this anti-fall protector of startup, and the tight roller of these pincers is mechanically stopped on anti-fall track and is ended falling of this charging hopper.
If got rid of subsequently descending cause out of control, then this charging hopper only need to upwards be walked about a bit of distance so that this anti-fall protector self-return.
Also see that anti-fall track 4 is installed on the installed part 40 this moment in Fig. 7.Here, the end face of the anti-fall track 4 of T shape is fixed with the power transmission fit system by fishbolt 39 in both sides, and fishbolt is clamped the edge of this end face.Because this anti-fall track only is installed on its bearing with fishbolt, so direction is moved this anti-fall track only stopping when this unexpected crash safety device triggers startup, at this, is provided with fixed stop in order to limit this to move.Thus, the overwhelming majority of Brake Energy is imported into this tracks, and this causes has protective effect ground energy to disperse for all members of participating.If there is not such arrangement, then the Brake Energy of the overwhelming majority changes the charging hopper dolly under about 20 millimeters theoretical braking distances of this system, thereby injury.
These installed parts 40 itself are installed on the guide rail 2 of charging lift by bolt as shown in Figure 7.
Fig. 8 illustrates the present invention who is in its extreme higher position lift of feeding, on this position, charging hopper 1 by take turns 13 and the cooperation cooperation of auxiliary guide rail 41 tumble.Also can see this moment, charging hopper 1 is hung on the side members 15 of dolly in bottom roller 11 zones for this reason rotationally.Because anti-fall protector 3 is arranged on the dolly 10, so the rotational motion of anti-fall protector and charging hopper 1 is irrelevant, thereby on this position, also realized the secure ratch of this charging hopper by unexpected crash safety device.
Fig. 9 illustrates the charging hopper that is in now on the 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 protector and detouring through upper directive wheel and lower directive wheel.If do not exceed predetermined speed this moment, then this limiter of speed rotates as normal directive wheel, and this charging lift moves downward in anti-fall not start of protector situation.If but charging hopper surpasses predetermined downward speed, then this control cord is triggered again anti-fall protector by locking and itself, and the anti-fall track that this anti-fall protector is established in side is stopped and ended this charging hopper.
At this moment, anti-fall track 4 consists of with straight form, just as tracks 2 is above it in zone and the middle section.Therefore, anti-fall track 4 still ends at before the below end of this tracks, especially the access of this tracks with bend 23 below before the section.Otherwise, this anti-fall protector can appear in the tumble motion and tilt with anti-fall track 4 of this lower zone internal cause dolly.Because the Bottom Runby of this charging hopper in this zone is not too large, so here, this anti-fall protector also no longer is absolutely necessary.
