Abstract

A grab bucket without leakage is composed of two individual and integral buckets with same shape, upper and lower pulleys which are linked via steel cable, a pair of lower brace rods and a pair of linking rods. The upper end of said lower brace rods and linking rods are hinged to lower pulley. The lower ends of said lower brace rods is hinged with plates at bucket mouth. The lower ends of linking rods are hinge to brace rods. Its advantage is no leakage.

Description

Grab bucket without leakage

The present invention relates to a kind of grab bucket of loading and unloading the material that looses, is the improvement to existing grab bucket structure.

Grab bucket is to cooperate weight-lifting equipment to carry out the special tool accessory of loose unpacked material loading and unloading operation, along with improving constantly of weight-lifting equipment load-bearing capacity, the tonnage of grab bucket is also from initial one ton of up till now more than 80 ton, in order to improve the extracting ability, adapt to the characteristic of crawled goods, the grab bucket structure is updated, its version has six, seven kind more than, but these structural changes only are on the drive mechanism of grab bucket, and as the bucket body that directly grasps material, then do not have the variation of essence.Entered since the eighties, the volume of goods loaded and unloaded of the material that some particles are little, flowing power is strong especially (as Bulk Grain, aluminium oxide, chemical fertilizer etc.) constantly rises, the loading and unloading of above mentioned goods are to rely on a kind of traditional two Hubei Province plate to close up the formula grab bucket, in order to prevent that material spills along seam in the handling process, it is to rely on half shape quarrel snap to none slit of two symmetrical splits to come leakproof, and for example existing several leakage-proof structure forms: 1, the cutting edge place adds the sealant bar on skip body; 2, cutting edge is made the intersection serration type; 3, double blade or thickening cutting edge thickness of slab.The common feature of said structure design concept is sealing, rigidity and an intensity of strengthening the butt seam place, and anti-wear.But by practice, adopt said structure to come leakproof to be difficult to fundamentally solve the leakproof problem, and also bring some other defectives, as after using a period of time, skip body deform (as the grab bucket with the shipment hull bump or the bucket body insufficient strength), two cutting edges can not close up, and grab bucket can't be worked; On the other hand, for resistance to deformation and wear-resisting, the thickening of the thickness of slab of grab bucket, Heavy Weight makes grab bucket extracting ability reduce under the load that hoisting crane allows.As seen from the above analysis, adopting two quarrels to align leakproof then is substantive defect in the design.How overcoming above-mentioned defective, is harbour handling operating personnel urgent problem.

The purpose of this invention is to provide a kind of grab bucket without leakage, it can solve the problem that spills in the grab bucket operation.

In order to achieve the above object, technical scheme of the present invention is: it comprises the switching steel rope, top sheave, the a pair of bucket body that is symmetrical arranged, between top sheave and two bucket bodies, be provided with a pair of strut, the type of attachment of strut and top sheave and two bucket bodies is hinged, it is characterized in that: the identical bucket body of two shapes is integral type bucket body independently separately, below top sheave, be provided with a lower sheave, on, connect by steel rope between the lower sheave, the upper end of a pair of lower supporting rod and pair of links is hinged on the lower sheave, the lower end of lower supporting rod is hinged on the plate body of quarrel of bucket body, its articulated position is in the interval at inboard, 1/2 place to quarrel bore 3/4 place of quarrel bore (inwardly starting at from the outward flange of quarrel), the lower end of connecting rod is hinged on the strut, its articulated position is more than the hinge-point of strut and bucket body, below 1/2 of strut height, the articulated position of strut and bucket body is in bucket body top quarrel outer edge.

The plate shape of lower supporting rod and bucket body hinged place is a lug shape.

The present invention compares with existing technology and has the following advantages and good effect: 1, two bucket bodies are integral type bucket body independently separately, the combined action of lower supporting rod and connecting rod in addition, both satisfy two bucket bodies and closed up the requirement that takes material mutually, the quarrel of bucket body up after closure was finished, seamless between two bucket bodies, thereby fundamentally eliminated the problem that spills from seam, and the loss and the environmental pollution of goods have been reduced.2, because this grab bucket need not the alignment of two bucket body cutting edges, even certain distortion takes place bucket body, grab bucket still can continue operation, therefore improves greatly the service life of grab bucket.3, because eliminated the problem of spilling, so the requirement of mechanical characteristicss such as bucket body intensity, resistance to deformation, resistance to abrasion is corresponding lower, the attenuation of bucket body thickness of slab has alleviated the deadweight of grabbing bucket, and grab bucket extracting ability improves.

Below in conjunction with accompanying drawing the present invention is described in detail.

Fig. 1 is a front view of the present invention;

Fig. 2 is a lateral plan of the present invention.

1, strut; 2, top sheave; 3, lower sheave; 4, lower supporting rod; 5, connecting rod; 6, bucket body; 7, open and close steel rope; 8, steel rope; 9, lug; 10, grab bucket.

Referring to Fig. 1 and Fig. 2, in order to eliminate existing grab bucket spills material from the butt joint slit of two bucket bodies phenomenon, design of the present invention is: after taking material, the quarrel that makes bucket body up.Its technical scheme is: the identical bucket body 6 of two shapes is integral type bucket body independently separately, like this can be after closure, two bucket bodies 6 shoulder to shoulder and quarrel up.Below top sheave 2, be provided with a lower sheave 3, connect by steel rope 8 between the upper and lower pulley 2,3, the upper end of a pair of lower supporting rod 4 and pair of links 5 is hinged on the lower sheave 3, the lower end of lower supporting rod 4 is hinged on the lug 9 of quarrel plate body of bucket body 6, its articulated position is in the interval at inboard, 1/2 place to quarrel bore 3/4 place of quarrel bore (inwardly starting at from the outward flange of quarrel), in the present embodiment, its position at 1/2 place inboard partially place.The lower end of connecting rod 5 is hinged on the strut 1, its articulated position more than the hinge-point of strut and bucket body, below 1/2 of strut height, in the present embodiment, its position is located on the lower side at 1/2 of strut height.Be provided with a pair of strut 1 between top sheave 2 and two bucket bodies 6, strut 1 is hinged with the type of attachment of top sheave 2 and two bucket bodies 6, and the articulated position of strut 1 and bucket body 6 is in bucket body 6 top quarrel outer edge.

When the material that looses is carried out loading and unloading operation, grab bucket 10 is under the supporting of a rope of hoisting crane (two rope), bucket body 6 relies on deadweight and opens, in opening procedure, lower supporting rod 4 and connecting rod 5 press down bucket body 6, make two bucket bodies 6 open (dotted portion among Fig. 1), hoisting crane is carried another root hoisting rope, and closed material grasping is carried out in grab bucket 10, two bucket bodies 6 close up and take material (as loosing chemical fertilizer, aluminium oxide and Bulk Grain etc.), bucket body 6 is at strut 1, under the combined action of lower supporting rod 4 and connecting rod 5, overturn, during closed the end, the quarrel of two bucket bodies 6 " shoulder to shoulder " up, therefore, do not have seam between two quarrels, thoroughly solved the problem that spills that existing grab bucket exists.
