Abstract
A kind of bulk material pile, taking equipment, it is by fixing existing pair of crossbeam gate-type bucket wheel bulk material pile, reclaimer moved cross beam low level the lifting mechanism of cancellation entablatrance and portable beam.But replenished by the windrow operation chassis that can move along crossbeam and be installed on the chassis, and heap in the crossbeam, got the transition hopper between the stockplling belt machine on material transmission belt machine and the operation chassis and the windrow mechanism of stockplling belt machine luffing control setup formation to the radially-protruding luffing stockplling belt of crossbeam machine.Simultaneously, huge and trailer crossbeam servo-actuated and relative position conversion have been saved because crossbeam is fixed by low level.
Description
The invention belongs to bank, taking equipment field in the operation Transport Machinery.
Big and pile, get frequent place (as thermal power plant coal piling field) and all corresponding bulk material pile, taking equipment must be arranged in diffusing material (as coal) amount of storage, up to the present the employed bulk material pile in home and abroad, taking equipment mainly contain two kinds of versions.A kind of is cantilever type bucket-wheel stacker, reclaimer, and its keystone configuration has support, the cantilever of rotatable and luffing.Be installed in the bucket wheel of cantilever front end, the bulk cargo belt conveyer, complete machine traveling gear and control setup, this equipment belongs to old product, though now also some local uses, except finishing the basic function, do not have what strong point by comparison.Its weakness is that cantilever one end supports.Support is huger, complex structure.The rotating mechanism difficulty is with high investment big.Because bucket wheel is installed in the cantilever far-end.When resistance was big in the shovel material, bigger to the assembled machine balance influence, working stability was relatively poor, simultaneously owing to the restriction that is subjected in the jib-length design.It is long-pending also restricted that capping is carried out in work.
Another kind of form claims gate-type (or bridge-type) bucket-wheel stacker, reclaimer.It is mainly by across the door frame of stock ground (wide about 50 meters) (by two side stands and entablatrance is fixedly connected be integral), moved cross beam that can ascending, descending in door frame, be installed in heap in the crossbeam, get the material belt conveyer and be installed on the crossbeam and can vertically move and be the bucket wheel of S. A. along crossbeam with the crossbeam.The trailer that is connected the interior belt feeder of moved cross beam and system's belt feeder (transmission belt machine between thing place and the coal combustion equipment is unloaded at harbour, station etc.), whole traveling gear and control operating control, its advantage is that beam is striden support greatly by two ends, and is more steady than cantilevered, and the work area coverage is big etc.Its weakness one is that complete machine is tall and big.Entablatrance is high about 20 meters.Machine gravity is about more than 10 from bearing surface, is subjected to natural power environment (wind, rain) influence bigger, although strengthen the cross-tie span, still has labile factor.With the multiple amount of material big (about 350 tons), because quality is big, the center of gravity height, during complete machine walking start-stop, the rotator inertia square is big, is again a labile factor.Second weakness is that structure is complicated, as huge support.The ability of portable beam lifting mechanism.Synchronism is had relatively high expectations, and for satisfying heap, get the material bidirectional transmission, minimumly in the portable beam will establish three belt feeders.Article two, play the transmitting effect of the different directions of heap, material extracting operation on the top of portable beam (respectively accounting for the partly near of beam).Article one, the bottom (length is slightly larger than half of beam) that is located at portable beam can be moved along beam, accepts the supplied materials of top belt feeder.When the windrow operation, at mouth material is dispensed in to intend pushing away and put the position.When material extracting operation, be transported on the trailer belt feeder.Because moved cross beam must have high-order homework, this just exists belt feeder and low level system belt feeder in the high-order crossbeam that the bigger discrepancy in elevation is arranged.This just must have the mechanism of linking is trailer.By oblique ascension (falling) belt feeder of trailer, material is served (or sending down) in order to guarantee bulk cargo adhering on belt.The elevation angle of oblique ascension belt feeder is limited, must strengthen the length of trailer like this, so the trailer of existing device is long all about in the of 50 meters.The 3rd weakness is that the work match routine is more, and road-holding property is poor, as when the windrow, removes at intending the windrow position and moves complete machine, also will rise (falling) moved cross beam, the heap of moving beam bottom, gets the material belt feeder, makes it the top of output in the windrow position.To cross over a plurality of belt feeders in the bulk cargo transmission, as when the windrow, bulk cargo is at first fallen on the trailer belt feeder, through the trailer belt feeder be transferred to moved cross beam top heap, get the material belt feeder on, be transferred on the ingredients belt of crossbeam bottom through this belt feeder again, throw then on stockpile, the bulk cargo that bucket wheel scoops up when getting material drops on the belt feeder on crossbeam top, be transferred to by this belt feeder on the ingredients belt of crossbeam bottom, the cohesive end that bulk cargo is transported to crossbeam and trailer by this belt feeder is accepted and is transferred on system's belt feeder by the trailer belt feeder again.Here also have one to become by windrow and to get material (or inverse process) a trailer head position conversion process must be arranged, reason is: owing to belt feeder and system's belt feeder on the portable beam, when existing high drop to get material, bulk cargo does not allow directly to fall on system's belt feeder, must deliver on system's belt feeder through the trailer belt feeder, this just produces a trailer head (near portable beam one end) again will be according to piling, get the different operation conversion of material and the relative position of portable beam.Just the trailer head will be higher than portable beam top belt feeder and is in and can be thrown into material on the position of this belt feeder during windrow.When material extracting operation, be reduced to the portable beam bottom, be in and can accept the bottom belt feeder and throw on the position of the material that gets off, an existing here height changes, the radially variation of forward and back of a relative portable beam is arranged again, variation to the trailer head is a technical barrier, although existing than the failure-free mode of motion, the trailer evolution will make structure complicated, increase operating sequence, simultaneously huge trailer motional inertia reaches the impact to door frame, also is a labile factor.
For overcome existing bucket-wheel stacker, get material equipment huge, complicated, make weakness such as difficulty, operability difference, the present invention provides a kind of brand new bucket-wheel stacker, gets material equipment under the situation that influences the existing device functions of use not, its purpose is simplified apparatus structure reduced volume, improve the stability of road-holding property and work.
The present invention passes through the frame mode that the cantilever luffing adapts to material stack height at absorption gate-type bucket-wheel stacker, reclaimer two end supports and cantilever type bucket-wheel stacker, reclaimer, and carries out comprehensive and the creation generation.
Its concrete structure is, the moved cross beam low level of existing gate-type bucket-wheel stacker, reclaimer is fixed, and removes the entablatrance high about 20 meters that is in that only plays the captive joint effect in the existing equipment, removes the portable beam jacking system, the support at simplification crossbeam two ends.Simultaneously two-layer up and down totally three belt feeders of the crossbeam in the existing equipment are transformed into a belt feeder of the full beam of perforation that is positioned at beam top, the bulk cargo that is provided with on this beam in the cover windrow work passes on and stacking mechanism.Accompanying drawing 1 is the front and the side schematic view of this mechanism.Wherein 1 is can be along the windrow operation chassis of original bucket wheel orbit operation on the beam.Its operation actuating unit can adopt the form identical with the bucket wheel actuating unit.The 2nd, be fixed on the operation chassis, make the heap in the crossbeam, the belt of getting material transmission belt machine passes the height (height of the following hopper upper edge that will speak of) and the idler pulley and the changed course of the crossbeam that turns back that move chassis and make it to rise needs and rolls, 3 is hopper, its effect is to accept the bulk cargo sent here along crossbeam and through end opening material is emitted, its size is according to flow design, its shape is determined according to the cooperation and the geometric relationship of neighbouring device, 4 is that an end is connected on the operation chassis base plate, the other end is along the radially-protruding stockplling belt machine of crossbeam, it is connected on the chassis base plate, the bulk cargo carrying of flowing out from the hopper lower part outlet is come, carry and leave and intend on the stowed location.
Because the crossbeam of transmission belt machine is housed to be fixed by low level, this has just obtained heap, get the effect of the very little discrepancy in elevation of material belt feeder and system's belt feeder, not only can make the length that under the condition that keeps protocercal tail car belt feeder ramping angle, has shortened trailer greatly (be about 10 meters, only be existing equipment 1/5th), and the supplied materials that makes belt feeder from crossbeam in material extracting operation is directly fallen on system's belt feeder.This with regard to having avoided in the original equipment because must be transferred on system's belt feeder and the structure difficult problem of trailer head position mapping device must be arranged through the trailer belt feeder, only need there be corresponding bulk cargo guide groove (or bucket) just passable with operational inconvenience, owing to heap in the crossbeam, get material transmission belt machine end between the trailer belt feeder is upper and lower, this just needs and is arranged in the heap of the top trailer belt feeder being thrown bulk cargo guiding crossbeam down and gets the guide groove (or bucket) of material transmission belt machine to satisfy windrow work.Have be positioned at the below with crossbeam heap, get the bulk cargo on the material transmission belt machine, be thrown into the guide groove (or bucket) of system's belt feeder, to satisfy the material work of getting.The available steel plate of groove (or bucket) surrounds rectangle, according to piling, get the length that material transmission belt machine stretches out on the crossbeam, determines that each one and the integral body of groove (or bucket) is put, and is fixed on the end of crossbeam.Accompanying drawing 2 is the form of this guide groove (or bucket) and the scheme drawing that concerns with neighbouring device.Wherein 5 is windrow guide groove (or bucket), and 6 for getting material guide groove (or bucket), and 7 is system's belt feeder, and 8 for piling, get material transmission belt machine in the crossbeam, and 9 is trailer.If upper and lower two guide grooves (or bucket) shell is made one, in establish kicker baffle and also can.
