The utility model belongs to reclaimer equipment, and particularly a kind of bulk cargo loading and unloading are with the automatic deflection adjusting material aligning gear of reclaimer.
Background technology
As everyone knows, in bulk cargo accumulating handling processs such as harbour, power plant, steel mill, ore stock ground, adopt traditional reclaimer or stacker-reclaimer to carry out discharging usually; At the material aligning gear of this reclaimer blanking buffering place installing by manual regulation; This material aligning gear is made up of regulating plate, latch, latch orifice plate, and symmetrical hinged regulating plate on two relative above the square discharging opening in hopper bottom lateral walls connects the latch orifice plate on each regulating plate plate face; Openings of sizes according to two regulating plates; On the latch orifice plate, be processed with pin hole accordingly, the size of opening as required is when promoting two regulating plates to needed pin hole by hand; Immediately latch is inserted respectively in two pin holes, it is to carry out grade adjusting that has of openings of sizes through the different pin holes position of regulating on the latch orifice plate.Through its patent No. of patent retrieval 200720017074.2 a kind of " bulk cargo loading and unloading are with the leading screw adjusting material aligning gear of reclaimer "; Its structure is included on the two relative madial walls of discharging opening top, with linkwork symmetric arrangement regulating plate, and on every regulating plate, adorns a cover leading screw system, adjusts discharging point through the manual regulation leading screw; This leading screw is regulated material aligning gear, though had some progressive than the former, but still has the shortcoming and defect part: since above-mentioned dual mode all needs operate manually, both operated heaviness, difficulty, take a lot of work again; And in control process, can occur inevitably causing adjusting not in place because of human error; Simultaneously above-mentioned two kinds of aligning gears all can't solve the cables pipe causes on the funnel of center cantilever and be turned back to belt deviation and the spreading phenomenon that materials flow changed course that different angles cause is caused, and make oppositely to get the material ability and seriously descend.
Summary of the invention
The utility model is intended to the shortcoming and defect part that in above-mentioned technology, exists, and the automatic deflection adjusting material aligning gear of a kind of bulk cargo loading and unloading with reclaimer is provided; This automatic deflection adjusting material aligning gear is not only reasonable in design, and compact conformation had both adopted mechanization to replace manual operations; Realize the automatic centering adjusting through PLC numerical control treater again; And have the production efficiency height, but step-less adjustment prevents ground belt deviation, spreading; Advantages such as the minimizing belt weares and teares, and practicality simple to operate and use are very convenient.
The purpose of the utility model is to adopt following technical scheme to realize: described bulk cargo loading and unloading are with the automatic deflection adjusting material aligning gear of reclaimer; It is characterized in that: through the four-bar linkage of the hinged drive mechanism of hinge first, described four-bar linkage is made up of guide cell body, hinge second, A oscillating deck, hinge third, B oscillating deck, hinge second and connecting rod on the suspension bracket of a side above the hopper discharging opening; Block is compressed by bolt with two upper inside wall in the corresponding guide cell body in belt conveyer middle position and through hinge fourth hinged A oscillating deck of symmetry and B oscillating deck; Described A oscillating deck is " < " shape; Its epimere is hinged through hinge third and driver train; The head of its A oscillating deck is hinged through an end of hinge fourth and connecting rod, and the other end of described connecting rod is hinged through the head of hinge fourth and B oscillating deck, and described oscillating deck B is " < " shape; On two hinge second of described hinged A oscillating deck and B oscillating deck, respectively install a stored program controlled by the mass flow sensor of PLC control.
Described driver train adopts Electrohydraulic push rod or adopts hydraulic ram.
It is described that " the A oscillating deck of < " shape is with " the lower plate Duan Jun of the B oscillating deck of < " shape processes and swing plate body all-in-one-piece baffle plate.
Because the driver train in the utility model adopts Electrohydraulic push rod or oil cylinder, and is articulated on suspension bracket and the A oscillating deck through hinge, A oscillating deck and B oscillating deck and connecting rod constitute a four-bar linkage again through hinge.When material is fallen on each oscillating deck; Mass flow sensor through connecting oscillating deck to detect respectively the inventory on the plate of rolling to each side; The signal that the mass flow sensor goes out becomes the analog signals of 4～20mA through signal amplifier and signal transmitting device, this signal is incorporated among the PLC handles; When the materials flow signal of the mass flow sensor of A oscillating deck during greater than the signal of the mass flow sensor of B oscillating deck; Then PLC sends signal; Make Electrohydraulic push rod or oil cylinder " lift " action; When the both sides sensor goes out to roll to each side plate stream deviation when being no more than setting value, then Electrohydraulic push rod or oil cylinder " lift " action and stop; Vice versa; When the materials flow signal of the sensor of B oscillating deck during greater than the signal of A oscillating deck sensor; PLC sends signal; Make Electrohydraulic push rod or oil cylinder " fall " action, when the both sides sensor goes out to roll to each side plate stream deviation when being no more than setting value, then Electrohydraulic push rod " falls " action and stops.Change the stroke of adjusting Electrohydraulic push rod or oil cylinder through its signal, cause four-bar linkage and move the angle of regulating two oscillating decks, thereby reach the purpose of adjustment blanking position.
The comprehensive above technical scheme of being taked, the purpose of realization the utility model.
The characteristics of the utility model are: adopt Electrohydraulic push rod or oil cylinder and a cover four-bar linkage and two bearing pin sensors to realize automatic immediate ground adjustment materials flow direction; Solved well owing to go up cantilever that the cables pipe causes in the funnel of center and be turned back to belt deviation and the spreading phenomenon that materials flow changed course that different angles cause is caused; It is unaffected to have guaranteed to get the material ability, has improved the service efficiency of reclaimer greatly.
Therefore, the utility model is not only reasonable in design, compact conformation; Both adopted mechanization to replace manual operations, and realized the automatic centering adjusting through PLC numerical control treater again, and have the production efficiency height; But step-less adjustment; Prevent ground belt deviation, spreading, reduce the belt wearing and tearing, practicality simple to operate with use advantages such as very convenient.
