Abstract
The invention relates to a shear type leakproof grab bucket, which is particularly used for a crane to load and unload cargos, belonging to the technical field of crane equipment. The shear type leakproof grab bucket mainly comprises a leakproof bucket body, a lifting frame, chains, a left grab bucket arm, a right grab bucket arm, an upper pulley block and a lower pulley block, wherein lifting ropes are connected to the upper sides of both ends of the lifting frame; the chains are connected to the lower sides of both ends of the lifting frame; the lower ends of the chains are connected with both sides of the leakproof bucket body; the left grab bucket arm is hinged with the right grab bucket arm through a central pin; and the left grab bucket arm and the right grab bucket arm are provided with the upper pulley block and the lower pulley block respectively. The shear type leakproof grab bucket has a simple, compact and reasonable structure; the leakproof bucket body has a good leakage-proof effect; the closing and opening moment is not reduced in the closing and opening process that the grab bucket grabs materials; the track of a bottom cutting edge of the grab bucket approximates to a straight line when the grab bucket grabs materials; and the shear type leakproof grab bucket has light self weight and large grabbing ratio, and greatly improves the loading and unloading operation efficiency.
Description
Technical field
The present invention relates to a kind of scissors Leakage-proof Clamshell, specifically be used for the cranage goods, belong to the crane facility technical field.
Background technology
In prior art, the jaw opening width of general two jaw plates grab buckets is limited, and grab bucket its closed moment in closing course is more and more littler, and the track that the jaw cutting edge forms in goods is a circular arc.Its weak point is that grab bucket opens that to grasp the shared horizontal area of goods too little, thus when grasping the less goods of proportion the extracting amount very little, and the bottom of more fragile storage cargo receptacle is like cabin bottom, the bottom in goods place etc.Work efficiency is lower, can not satisfy need of work.
In the loading and unloading of Bulk Grain, the chemical fertilizer that looses, the bulk goods such as soda ash that loose, because the internal friction coefficient of these bulk goods is little, good fluidity, the jaw cutting edge of grab bucket have a slit slightly, and goods will run off.Not only wasted a large amount of goods, the environment of having gone back gross pollution.Therefore, solving leakage in the cargo handing is the unusual urgent problem of stubborn problem.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point; Thereby a kind of scissors Leakage-proof Clamshell is provided, grasps in the closing course of material in grab bucket, closed moment is increasing; The track of grab bucket shear blade mouth is similar to straight line during material grasping; From heavy and light, grasp than big, greatly improved handling labor efficient; The application of Leakage-proof Clamshell has simultaneously reduced the waste of bulk goods in the handling process.
According to technical scheme provided by the invention; The scissors Leakage-proof Clamshell mainly comprises anti-infundibular body, suspension bracket, chain, left side grab bucket arm, right grab bucket arm, top sheave group and downslide wheels; Above the suspension bracket two ends, connect the up-down rope; Below, suspension bracket two ends connects chain, and the chain lower end connects anti-infundibular body both sides.Said anti-infundibular body comprises two symmetrical bucket lobes, and the bucket lobe is connected left and right grab bucket arm lower end.Said left and right grab bucket arm is hinged through center pin.Be respectively equipped with top sheave group and downslide wheels on the said left and right grab bucket arm.Said top sheave group comprises that two pulleys connect through a upper pin.Said downslide wheels comprise that a pulley connects through a lower bearing pin.Be respectively equipped with a cover of wedge joint on the said left and right grab bucket arm.The other switching rope that is provided with of said suspension bracket, the pulley that the switching rope is walked around in top sheave group and the downslide wheels is connected on the cover of wedge joint at last.
Said anti-infundibular body comprises two symmetrical bucket lobes, and the bucket lobe is connected left and right grab bucket arm lower end.Said two bucket lobe junctions are provided with tooth engaged.Said top sheave group comprises two pulleys, connects through a upper pin.Said downslide wheels comprise a pulley, connect through a lower bearing pin.
Compared with present technology the present invention has the following advantages: the present invention is simple, compact and reasonable for structure; Reliable operation, anti-infundibular body has good leak preventing effect; Grasp in the closing course of material in grab bucket, closed moment does not reduce, and the track of grab bucket shear blade mouth is similar to straight line during material grasping, from heavy and light, grasps than big, has greatly improved handling labor efficient.

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 mainly comprises anti-infundibular body 1, suspension bracket 2, chain 3, left side grab bucket arm 4, right grab bucket arm 12, top sheave group 9 and downslide wheels 11; Above suspension bracket 2 two ends, connect up-down rope 7, below, suspension bracket 2 two ends connects chain 3, and chain 3 lower ends connect anti-infundibular body 1 both sides.Said anti-infundibular body 1 comprises two symmetrical bucket lobes 13, and bucket lobe 13 is connected left and right grab bucket arm 4,12 lower ends.Said left and right grab bucket arm 4,12 is hinged through center pin 5.Be respectively equipped with top sheave group 9 and downslide wheels 11 on the said left and right grab bucket arm 4,12.Said top sheave group 9 comprises two pulleys, connects through a upper pin 14.Said downslide wheels 11 comprise a pulley, connect through a lower bearing pin 15.Be respectively equipped with a cover of wedge joint 6 on the said left and right grab bucket arm 4,12.Said suspension bracket 2 other being provided with open and close rope 8, and switching rope 8 is walked around top sheave group 9 and is connected at last on the cover of wedge joint 6 with downslide wheels 11 interior pulleys.
Said two bucket lobe 13 junctions are provided with tooth engaged 10, can better seal bucket body, prevent that material is scattered out in bucket body.
Principle of work of the present invention is: in when work, descending through hoisting crane opens and closes rope 8, and left and right grab bucket arm 4,12 is opened to two side shiftings, and anti-infundibular body 1 is opened thereupon.Through hoisting crane decline up-down rope 7, the anti-infundibular body of opening 1 is fallen on the bank thereupon then.Open and close rope 8 through the hoisting crane pull-up, open and close rope 8 and draw left and right grab bucket arm 4,12 over to one's side, anti-infundibular body 1 closes up thereupon.Two tooth engaged 10 that bucket lobe 13 junctions are provided with through anti-infundibular body 1 can better seal bucket body, prevent that material is scattered out in bucket body.Through crane lifting up-down rope 7, the anti-infundibular body 1 of grabbing full with substance is raised at last, transports to the emptying point of appointment and accomplishes discharging.
