Description

A kind of garbage grab bucket crane
Technical field
The present invention relates to crane technical field, more particularly to a kind of garbage grab bucket crane.
Background technology
With developing rapidly for modernization science and technology, and the raising of the level of urbanization, industrial refuse and house refuse are every Year all largely produces and shows a rising trend, and environmental pollution is serious.And in terms of garbage disposal, needed in garbage processing procedure Carried, stirred, collapse of setting, being fed intake, generally required garbage grab bucket handling mobile crane and carry out carrying rubbish.And since rubbish is big It is in scrappy state, grab bucket can not often pick up substantial amounts of rubbish quickly, and work efficiency is low, and the loading capacity of crane more Suffer from the limitation of steel wire rope.
The content of the invention
The object of the present invention is to provide a kind of garbage grab bucket crane, increases the rubbish amount of picking up, and improves loading capacity.
The present invention above-mentioned purpose technical scheme is that:A kind of garbage grab bucket crane, including Track girder, the girder moved along track girder, the moving cart moved along girder and the boom hoisting being installed in moving cart, institute Stating boom hoisting includes lifting reel, grab bucket and steel wire rope, and the lifting reel is installed in the moving cart, the steel wire Rope is connected between lifting reel and the grab bucket, and the grab bucket includes the pawl arm of bearing, several circle distributions on bearing With the hydraulic cylinder for promoting single pawl arm swing, the upper end of the bearing is equipped with movable pulley, and one end of the steel wire rope is around being located at State on lifting reel, the other end is around the movable pulley and is fixed in the moving cart;The upper end of the pawl arm is hinged on On the bearing, one end of the hydraulic cylinder is hinged on the bearing, and the other end is hinged on the pawl arm, and the pawl arm is extremely Rare side is equipped with side pawl, and one end of the side pawl is articulated with the pawl arm, and the other end extends to the lower end of the pawl arm, institute State and linkage mechanism is equipped between pawl arm and the side pawl, the hydraulic cylinder promotes the pawl arm swing simultaneously by the linkage mechanism Promote the side pawl to swing, when the pawl arm collapses or opens, the side pawl is laterally opened or is collapsed, institute to the pawl arm The swaying direction for stating side pawl is vertical with the swaying direction of the pawl arm.
Preferably, the linkage mechanism includes sliding block and first connecting rod, the pawl arm is equipped with sliding slot, the sliding slot Upper and lower ends are equipped with positive stop end, and the sliding block is slidably mounted in the sliding slot and is moved between upper and lower two positive stop ends, institute The one end for stating first connecting rod is hinged on the sliding block, and the other end is hinged on the side pawl, and the hydraulic cylinder is hinged on described Sliding block.
When Hydraulic Cylinder sliding block moves down, sliding block swings side pawl by first connecting rod, and side pawl is to pawl arm at this time Side is opened, and sliding block is continued to move to until when touching lower limit end, and driving pawl arm swing is collapsed, and the crawl area of pawl arm increases Greatly, rubbish crawl amount is increased;When hydraulic cylinder pulls sliding block to move up, sliding block swings side pawl by first connecting rod, at this time Side pawl is collapsed to pawl arm side, and sliding block is continued to move to until when touching upper limit end, and driving pawl arm swing is opened, and pawl arm is grabbed Area is taken to reduce, easy to discharge rubbish.
Preferably, the moving direction of the sliding block and the length direction of the first connecting rod form angle α, the size of α For 90 °≤α≤160 °.
Preferably, the full swing angle of the relatively described pawl arm of the side pawl is β, the size of β is 30 °≤β≤45 °.
Preferably, the sliding block is split structure, including the first sliding block set up and down and the second sliding block, it is described First sliding block is connected with the elastic component for being moved away from both with second sliding block, and the hydraulic cylinder is hinged on described first and slides On block, the first connecting rod is hinged on second sliding block.
Preferably, the first connecting rod includes first body of rod and second body of rod of articulated connection, first body of rod hinge Be connected on the side pawl, second body of rod is hinged on second sliding block, second body of rod and first sliding block it Between be equipped with second connecting rod, second sliding block relative to first sliding block move when, pass through the second connecting rod and drive the side Pawl is rotated relative to the pawl arm in the pawl arm rotation direction.
When pawl arm opens release rubbish, rubbish easily is clamped since side pawl collapses, rubbish, which is remained on pawl arm, to be influenced just Often release, therefore by setting split type sliding block, the first sliding block and the second sliding block produce opposite move when moving up sliding block It is dynamic, so as to pull side pawl to rotate by second connecting rod, side pawl is staggered with pawl arm, avoid clamping rubbish between the two.
Preferably, the pawl arm is equipped with rotation seat, the rotation seat is rotatably installed on the pawl arm, the side pawl Rotate on the rotation seat, the pivot center pawl arm opposite with the rotation seat of the relatively described rotation seat of side pawl Pivot center is vertical, the relatively described rotation seat of the side pawl is driven the side to the pawl arm lateral rotation, the rotation seat Pawl is rotated relative to the pawl arm to the pawl arm rotation direction.
Preferably, the bearing includes first support and second support, the first support and the second support are in It is horizontally disposed up and down, and the relatively described first support of the second support moves left and right, the movable pulley is installed on described first On stent, the pawl arm is installed in the second support.
Preferably, second support is connected between the first support and the 3rd stent, the second support Upper end is hinged in the first support, its lower end is hinged on the 3rd stent, the first support, the second support Parallelogram sturcutre is formed with the 3rd stent.
Beneficial effects of the present invention:The present invention opens side pawl when capturing rubbish, increases pawl by the side pawl of setting activity The crawl area of arm, improves grab bucket crawl amount;Side pawl is collapsed when discharging rubbish, realizes quick release rubbish, and will not incite somebody to action Rubbish is remained on pawl arm;And fixed pulley mechanism is employed between grab bucket and lifting reel, the moiety by weight of grab bucket is disperseed In moving cart, steel wire rope is born the weight of bigger, increase the cargo dead-weight of crane, reduce the work of lifting reel The rate of doing work, improves rubbish cleaning efficiency.
