Description

A kind of four bar linkage telescopic mechanisms
Technical field
The utility model relates to a kind of four bar linkage telescopic mechanisms, particularly relate to a kind of for hanging arm type bucket wheel stacker-reclaimer main frame and trailer be connected and heap is got four bar linkage telescopic mechanisms of conversion.
Background technology
Hanging arm type bucket wheel stacker-reclaimer is the ancestor of the modern chemical industry sparetime university bulk material high-efficiency appliance of handling continuously, mainly main frame and trailer, consists of.At present, the connection of main frame and trailer adopts the worm and gear telescoping mechanism usually.In order to meet the functional requirement of stacker-reclaimer, need to install two cover worm and gear telescoping mechanisms on every equipment, but the synchronism of worm and gear telescoping mechanism is poor, easily produce and agree the rail phenomenon.In addition, above-mentioned worm and gear telescoping mechanism complex structure, Installation and Debugging are loaded down with trivial details, manufacturing cost is high.
Summary of the invention
The purpose of this utility model is to overcome the weak point existed in above-mentioned technology, and a kind of simple in structure, reasonable in design, centering is accurate, cost is low four bar linkage telescopic mechanisms are provided.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise electric pushrod and actuating unit, described actuating unit comprises fixed link, transiting rod, portable bar and supporting base, the push rod end of described electric pushrod is connected with the portable bar hanger in the middle of being located at portable bar by steel rope, the other end of electric pushrod is rotationally connected by hinge and trailer, one end of described fixed link is fixedly connected with main frame, anti-overturning seat is installed in the below of the other end and the end by bearing pin and transiting rod is rotationally connected, the other end of described transiting rod is rotationally connected by an end of bearing pin and portable bar, the other end of described portable bar is rotationally connected by bearing pin and the twisted seat that is fixed on the supporting base top, described supporting base is fixed on trailer.
The utility model has the advantages that:
1, simple in structure, reasonable in design, centering accurately, low cost of manufacture, working service be easy;
2, not only realized being connected of trailer and main frame, and realized that windrow, feeding and material are by the conversion of three kinds of mode of operations,, when fixed link and portable bar interlock, realize windrow and feeding function, when fixed link and portable bar launch, realize that material passes through function.
The accompanying drawing explanation
Structural representation when Fig. 1 is the utility model windrow and feeding state;
Structural representation when Fig. 2 is the utility model material by state.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
From Fig. 1-Fig. 2, the utility model comprises electric pushrod 1 and actuating unit, described actuating unit comprises fixed link 3, transiting rod 4, portable bar 7 and supporting base 9, the push rod end of described electric pushrod 1 is connected with the portable bar hanger 6 in the middle of being located at portable bar 7 by steel rope 2, the other end of electric pushrod 1 is rotationally connected by hinge and trailer, one end of described fixed link 3 is fixedly connected with main frame, the below of the other end is equipped with anti-overturning seat 11 and is rotationally connected by bearing pin 5 and an end of transiting rod 4, the other end of described transiting rod 4 is rotationally connected by bearing pin 5 and an end of portable bar 7, the other end of described portable bar 7 is rotationally connected by bearing pin 5 and the twisted seat 8 that is fixed on supporting base 9 tops, described supporting base 9 is fixed on trailer.
The upper surface 10 of described anti-overturning seat 11 is plane.
Described portable bar 7 be shaped as the bow font, described fixed link 3 be shaped as " V " shape.
A kind of four bar linkage telescopic mechanisms of the present utility model comprise electric pushrod 1 and by fixed link 3, transiting rod 4, the actuating unit that portable bar 7 and supporting base 9 form, the push rod end of electric pushrod 1 is connected with portable bar hanger 6 by steel rope 2, the other end is rotationally connected by hinge and trailer, fixed link 3, transiting rod 4 and portable bar 7 join end to end successively, the other end of fixed link 3 is fixedly connected with main frame, the other end of portable bar 7 is rotationally connected with the twisted seat 8 that is fixed on supporting base 9 tops, supporting base 9 is fixed on trailer, thereby realize being connected of hanging arm type bucket wheel stacker-reclaimer trailer and main frame.
When fixed link 3 and portable bar 7 interlock, the center superposition of central blanking bucket before the funnel of trailer head and main frame.Now, if material unloads to the cantilever belt conveyor on jib through trailer, front central blanking bucket by system belt conveyor, and throw and unload to appointed place from the jib front end, thereby realize the windrow function of hanging arm type bucket wheel stacker-reclaimer; If the material taken by bucket wheel unloads to the cantilever belt conveyor of inverted running through stripper, then unload to system belt conveyor through the central blanking pipe, and transport material to appointed place by system belt conveyor, thereby realize the feeding function of hanging arm type bucket wheel stacker-reclaimer.
Electric pushrod 1 is received the material of PLC control system output by after the state transformation instruction, the push rod of electric pushrod 1 shrinks, under the pulling force effect of steel rope 2, bearing pin 5 clickwises of portable bar 7 in twisted seat 8, and drive transiting rod 4 rotates, after 21 ° of portable bar 7 clickwises, portable bar 7 collision limit switches also send command adapted thereto, main frame is received above-mentioned instruction and is advanced before backward, the push rod of electric pushrod 1 stretches out and reposition simultaneously, thereby fixed link 3 and portable bar 7 are launched, the center superposition of the funnel of trailer head and main frame rear center material-falling hopper, and then realize that windrow and feeding state transformation are that material is by the function of state.Now, material arrives rear center's material-falling hopper by system belt conveyor through trailer, then, by coal spout direct communication system belt feeder, transports material to appointed place.Otherwise material is windrow and feeding state by state transformation.
Four bar linkage telescopic mechanisms of the present utility model have not only been realized being connected of trailer and main frame, and have realized that windrow, feeding and material are by the conversion of three kinds of mode of operations, and simple in structure, reasonable in design, centering accurately, low cost of manufacture, working service be easy.
