Description
Technical field
The present invention relates to a kind of duplex timber grab, specifically be used to load and unload timber, belong to the crane facility technical field.
Background technology
At present, at the harbour, the timber loading and unloading of goods yard and cutting area grasp on, mostly relevant weight-lifting equipment is four tooth timber grabs if being equipped with.When timber grasps operation, because the cabin space is little, need the control grab bucket to grasp angle, the extracting efficient of four tooth timber grabs is just lower, makes that the handling labor of timber is heavy and dangerous.So, need a kind of high special-purpose timber grab of timber efficient that loads and unloads.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of duplex timber grab is provided, can in less operational space, load and unload timber, the unloading high efficiency; Balance is good, can run-off the straight in the extracting process; Can grasp very long timber, timber can not fracture, and has guaranteed lumber quality.
According to technical scheme provided by the invention; The duplex timber grab comprises that mainly a machine opens and closes rope, balance hanger, equalizer pulley, up-down rope, guide wheel, deck beam, top sheave, lower sheave, through beam, curved tooth bucket body, grab bucket switching rope, transition pulley and strut; Said balance hanger upper end connects the door machine through upper lift ring and opens and closes rope, connects equalizer pulley through the balance bearing pin in the balance hanger.
Said deck beam is provided with two transition pulleys that left-right symmetric distributes, and two transition pulley both sides are respectively equipped with a top sheave, and two top sheave left-right symmetric distribute.Be provided with the guide wheel of two symmetrical distributions in the deck beam upper end, connect the up-down rope on the deck beam on guide wheel side.
Said through beam has two, is arranged symmetrically in the deck beam down either side respectively.Through beam is provided with lower sheave.Said strut upper end and deck beam are articulated and connected, and lower end and curved tooth bucket body rear end are articulated and connected.Connect four pairs of curved tooth bucket bodies on said each through beam, four pairs of curved tooth bucket bodies are symmetrically distributed on through beam.Said curved tooth bucket body links into an integrated entity through first connecting rod and second connecting rod.Said through beam is provided with cover of wedge.
Said grab bucket opens and closes rope and is installed on the equalizer pulley, and two distribution that grab bucket opens and closes rope gets into top sheave again through guide wheel, transition pulley, top sheave and lower sheave, is fastened at last on the cover of wedge on the through beam.
Compared with present technology the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Can in less operational space, load and unload timber, the unloading high efficiency; Balance is good, can run-off the straight in the extracting process; Can grasp very long timber, timber can not fracture, and has guaranteed lumber quality.

Description of reference numerals: 1-door machine opens and closes rope, 2-balance hanger, 3-equalizer pulley, 4-up-down rope, 5-guide wheel, 6-deck beam, 7-top sheave, 8-lower sheave, 9-through beam, the curved tooth bucket body of 10-, 11-upper lift ring, 12-balance bearing pin, 13-grab bucket switching rope, 14-transition pulley, 15-cover of wedge, 16-first connecting rod, 17-second connecting rod, 18-strut.
The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
Shown in Fig. 1 ~ 2; The present invention comprises that mainly a machine opens and closes rope 1, balance hanger 2, equalizer pulley 3, up-down rope 4, guide wheel 5, deck beam 6, top sheave 7, lower sheave 8, through beam 9, curved tooth bucket body 10, grab bucket switching rope 13, transition pulley 14 and strut 18; Said balance hanger 2 upper ends connect the door machine through upper lift ring 11 and open and close rope 1, connect equalizer pulley 3 through balance bearing pin 12 in the balance hanger 2.
14, two transition pulley 14 both sides of two transition pulleys that said deck beam 6 is provided with the left-right symmetric distribution are respectively equipped with 7, two top sheave 7 left-right symmetric distributions of a top sheave.Be provided with the guide wheel 5 of two symmetrical distributions in deck beam 6 upper ends, connect up-down rope 4 on the deck beam 6 on guide wheel 5 sides.
Said through beam 9 has two, is arranged symmetrically in deck beam 6 down either side respectively.Through beam 9 is provided with lower sheave 8.Said strut 18 upper ends and deck beam 6 are articulated and connected, and lower end and curved tooth bucket body 10 rear ends are articulated and connected.Connecting 10, four pairs of curved tooth bucket bodies 10 of four pairs of curved tooth bucket bodies on said each through beam 9 is symmetrically distributed on through beam 9.Said curved tooth bucket body 10 links into an integrated entity through first connecting rod 16 and second connecting rod 17.Said through beam 9 is provided with cover of wedge 15.
Said grab bucket opens and closes rope 13 and is installed on the equalizer pulley 3, and two that grab bucket opens and closes rope 13 gets into top sheave 7 through guide wheel 5, transition pulley 14, top sheave 7 and lower sheave 8 respectively again, is fastened at last on the cover of wedge 15 on the through beam 9.
Principle of work of the present invention is: when work, up-down rope 4 keeps motionless, and hoisting crane control gate machine opens and closes rope 1 and descends.The decline that the door machine opens and closes rope 1 makes equalizer pulley 3 descend, and it is loose that the decline of equalizer pulley 3 makes that grab bucket opens and closes rope 13, and lower sheave 8 descends because of deadweight.Because the upper end of strut 18 is connected on the deck beam 6, keep motionless so be connected curved tooth bucket body 10 rear ends of strut 8 lower ends, the upper end of curved tooth bucket body 10 is driven by through beam 9 and descends, and curved like this tooth bucket body 10 has just opened.Controlling the curved tooth bucket body 10 of up-down rope 4 declines then arrives on the timber.
In the time of among timber is in open curved tooth bucket body 10; Hoisting crane control up-down rope 4 keeps motionless; The door machine opens and closes rope 1 and rises; Door machine switching rope 1 drives grab bucket through equalizer pulley 3 and opens and closes rope 13 past risings, and grab bucket opens and closes rope 13 and drives lower sheave 8 again toward rising, and this moment, curved tooth bucket body 10 slowly closed up.Promote up-down rope 4 at last, curved tooth bucket body 10 breaks away from stockpile, timber is transported to specifies the emptying point.
The present invention has at the cabin mouth big than hour unloading scope, and rate of discharging is high, and the good advantage of its balance.In picking up process, can not tilt, can grasp very long timber yet, timber can not fracture, and has guaranteed lumber quality, has greatly improved handling labor efficient.
