Description
Technical field
The present invention relates to construction machinery and equipment, particularly relate to a kind of retraction type stockyard self-adapting flexible bucket wheel device.
Background technology
Along with the fast development of China's economy, the demand of China to the major bulks such as coal and ore is surged, and has the bulk goods such as a large amount of coal, ore and ore in sand form to be transported to domestic by larger cargo ships every year.Harbour is the first transhipment station of these major bulkss, the course of conveying of bulk goods from boats and ships to stockyard is as follows: boats and ships → ship unloaders → belt feeder → bucket-wheel stacker reclaimer → stockyard, the course of conveying that bulk goods produces from stockyard is as follows: stockyard → bucket-wheel stacker reclaimer → belt feeder → truck-loading facilities → railway carriage, or stockyard → bucket-wheel stacker reclaimer → belt feeder → ship loader → boats and ships.Bucket-wheel stacker reclaimer is that bulk goods is come in and gone out the special continuous heap reclaimer device in stockyard, has the advantages such as heap feeding efficiency is high, material kind of comformability is good, reliability is high, easy and simple to handle, is applied widely in specialized bulk storage yard.
Although bucket-wheel stacker reclaimer has above-mentioned advantage, bucket-wheel stacker reclaimer feeding has a difficult point to fail to break through all the time, that is: after feeding completes, the stockyard bottom can remaining thick about 500mm material bed.Occur that the reason of this situation is because the bucket wheel of bucket-wheel stacker reclaimer is rigid body, the risk collided with heap Ground is there is when taking bottom material, light like this, bucket wheel and heap Ground may be caused all to sustain damage, heavy then bucket-wheel stacker is turned on one's side, cause serious accident.Harbour user is when using bucket-wheel stacker reclaimer material extracting operation, in order to prevent bucket wheel and heap Ground generation rigid collision, adopt the measure of restriction bucket wheel cantilever nutation height, make the hopper of bucket-wheel stacker reclaimer cantilevered head keep certain safety distance with heap Ground.Although adopt the bucket-wheel stacker reclaimer of this safety method can take most of material on stockyard, the difficult problem that the resistates bed of material that also result in, stockyard has thickness to be about 500mm all the time cannot take simultaneously.
At present, bulk storage yard does not have the equipment of clearing out a gathering place of specialty, loader is mainly used to carry out auxiliary operation of clearing out a gathering place for last one deck salvage stores, its main working process is: after the normal material extracting operation of bucket-wheel stacker reclaimer completes, start operation of clearing out a gathering place, loader enters stockyard and puts together to material remaining on stockyard, and the material of putting together is pushed into the stockpile with certain altitude, and bucket-wheel stacker reclaimer takes the stockpile that loader is put together more subsequently.Limited in one's ability due to loader each pusher bunch, therefore needs repeatedly to repeat above operation process of clearing out a gathering place, could realize the cleaning of the salvage stores in whole stockyard.
Adopting loader to carry out stockyard assists the advantage of operation of clearing out a gathering place to be: flexible, operation effectiveness of clearing out a gathering place is good, and good to heap Ground comformability, rear stockyard material of having cleared out a gathering place is residual few.Although adopt auxiliary the clearing out a gathering place of loader to have above advantage, also there is following very important defect:
1) work capacity of clearing out a gathering place is large, and efficiency of clearing out a gathering place is low.Stockyard salvage stores thickness is about 500mm, the inventory that need clear out a gathering place is huge, and loader single to push away the inventory of taking off limited, need loader constantly back and forth to carry out taking in product, loader taking in product efficiency is low, and limited in one's ability due to loader each pusher bunch, the material stack volume of putting together is little, the stockpile feeding that bucket-wheel stacker reclaimer is put together to loader is insufficient, and feeding efficiency is low, and the whole efficiency of the operation that causes clearing out a gathering place is low.
2) operation consumption of clearing out a gathering place is large.Because the efficiency of putting together of loader is low, cause the time of the whole operation of clearing out a gathering place of loader longer, cause self fuel consumption of loader when clearing out a gathering place comparatively large thus, and the power consumption of the equipment such as bucket-wheel stacker reclaimer, system belt conveyor of work compound is huge with it.
3) cost of equipment maintenance is large.Loader is when clearing out a gathering place operation, and the equipment such as system belt conveyor need to run always, and because loader is cleared out a gathering place, efficiency is low, the time of clearing out a gathering place is long, indirectly adds the time of run of yard equipment, adds the maintenance cost of yard equipment.
4) operating environment of clearing out a gathering place pollutes large.Clear out a gathering place operation time, the equipment such as loader, bucket-wheel stacker reclaimer, system belt consume energy in a large number, discharge a large amount of waste gas, cause larger environmental pollution.
Summary of the invention
The present invention proposes a kind of retraction type stockyard self-adapting flexible bucket wheel device, solves bucket wheel and ground and rigid collision occurs and cannot carry out stockyard and to clear out a gathering place the difficult problem of operation, while ensureing the normal feeding function of bucket wheel machine, have both operation function of clearing out a gathering place.Flexible bucket wheel device is arranged on the cantilevered head of bucket-wheel stacker reclaimer, flexible bucket wheel is when normal material extracting operation, its performance is consistent with traditional bucket wheel, but when carrying out clearing out a gathering place operation, adopt the hopper of the bucket-wheel stacker reclaimer of retraction type stockyard self-adapting flexible bucket wheel device and ground without the need to reserving certain safe altitude again.Cantilever nutation height in the process of horizontal hunting keeps constant, when causing flexible bucket wheel and earth surface because heap Ground is rough and uneven in surface in reclaiming process, flexible bucket wheel is under the effect of ground reaction force, hopper is around the hinge inside flexible retraction automatically of its tail end Connection Block, avoid flexible bucket wheel and heap Ground generation rigid collision, leave ground rear hopper and automatically return to open configuration, thus achieve bucket-wheel stacker reclaimer can not produce destruction to equipment itself and heap Ground object when clearing out a gathering place operation.
