Abstract
The utility model relates to a monocable grab bucket floating in water, which belongs to cranes and is used for load suspending parts or devices of cranes, capstan machines, winches or tackles. The utility model is characterized in that a stay bar, a bucket body, a deck beam, etc. of the monocable grab bucket can be made of high intensity engineering plastics with lighter self weight; both sides of the stay bar are respectively provided with three or four independent small rubber gasbags; large rubber gasbags are arranged on the bottom boards of two sides of the bucket body; each rubber gasbag has a gas valve; side boards of the bucket body are provided with drain holes. The utility model can make the monocable grab bucket grab goods floating in water to enlarge the range of use of the monocable grab bucket, improve the utilization ratio of the grab bucket and reduce worker's labor intensity.
Description
Technical field
The utility model relates to and a kind ofly has the air bag that can inflate body and can float over single rope grab in the water, belongs to hoisting crane; The load that is used for hoisting crane, capstan engine, winch or coaster tangles part or device.
Background technology
In known technology, general artificial or the twin rope grab etc. of using remove rubbish or phytoplankton in the water surface, water.Its weak point be with manual work require great effort very much, efficient is low, or with twin rope grab and corollary equipment more complicated.And general single rope grab must drop on and just can open or close on the ground, can not finish on-off action in water.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of single rope grab that has the air bag that can inflate body and can float over underwater work is provided, thereby alleviate labor strength, make grab bucket and corollary equipment simpler, improved economic benefit.
The technical solution of the utility model is:
The strut of single rope grab, bucket body, deck beam etc. can select for use the lighter high-strength engineering plastic of deadweight (example: PBTB/PETB, proportion are less than 1.5 tons/cubic meter) to make.Be useful on the screw hole that air bag is installed on strut and the bucket body, mounting hole is arranged on air bag.3-4 independently small rubber air bag is installed respectively in the both sides of strut.Big rubber pneumatic bag is installed on the base plate of the both sides of bucket body, is had drainage opening on the bucket body side plate.Available binding bolt is fixed on air bag on strut, the bucket body, and gas valve is arranged on the air bag.The single rope grab of how much regulating with air bag quantity increase and decrease and charge air floats over the degree of depth in the water.
Compared with prior art, the utility model has the advantages that: single rope grab is floated in the water, grasp goods.Enlarge the range of use of single rope grab, improved the degree of utilization of grab bucket.Simultaneously, can alleviate working strength of workers and the supporting weight-lifting equipment of grab bucket is simplified, improve economic benefit and social benefit.
Description of drawings
Fig. 1 is the single rope grab in the water of floating over that is closed condition that the utility model proposes.
Fig. 2 is the single rope grab in the water of floating over of the open-shaped attitude that the utility model proposes.
Fig. 3 is one type the rubber pneumatic bag that the utility model proposes.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
In accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the utility model is made up of deck beam (1), strut (2), small rubber air bag (3), bucket body (4), big rubber pneumatic bag (5), steel rope (6), the middle bolster (7) that has the open and close device, through beam (8), gas valve (9), the binding bolt members such as (10) of single rope grab.
The framing member of single rope grab of the present utility model, example: strut (2), bucket body (4), deck beam available high-strength engineering plastics such as (1) are made.Have drainage opening on bucket body (4) side plate, it can be benefit from outflow in the hole that the sluicing hole size is closed back water with grab bucket.Big rubber pneumatic bag (5) is fixed on the base plate and the both sides of bucket body (4) with binding bolt (10); 3 to 4 small rubber air bags (3) are fixed on the strut (2).Each rubber pneumatic bag all has a gas valve (9).
The single rope grab that floats in the water should and be grabbed object and be matched various large and small rubber pneumatic bags (3) (5) in the water surface degree of depth before operation according to the deadweight of grabbing bucket, and should test in water several times the grab bucket after gas valve (9) inflation of rubber pneumatic bag and start working after the satisfaction.The open-shaped water of putting into of this single rope grab during work, relying on the buoyancy of big rubber pneumatic bag (5) or large and small rubber pneumatic bag (5), (3) that single rope grab is floated in the water is grabbed on the object, middle bolster (7) descends with steel rope (6) and contacts with through beam (8), and switching mechanism is combined into one them.Then, single rope grab steel rope (6) rises, and makes bucket body (4) closure, and water flows out from drainage opening and grabbed object and stay in the bucket body (4).Single rope grab is delivered on the destination grabbing object, and middle bolster (7) descends with steel rope (6) and contacts with through beam (8), and switching mechanism is opened, and open grab bucket is stayed the destination to goods, and single rope grab enters next circulation.End-of-job is opened gas valve (6) large and small rubber pneumatic bag (5), (3) is restored to the original state.The gas filled device of rubber pneumatic bag can be contained in the grab bucket, also can be contained on the hoisting crane.
The utility model is not worked as if not needing to float in the water, needs only large and small rubber pneumatic bag dismounting down, and just energy be worked with generally single rope grab is the same.
Claims (3)
1. one kind has the air bag that can inflate body and can float over single rope grab in the water, has deck beam (1), strut (2), small rubber air bag (3), bucket body (4), big rubber pneumatic bag (5), steel rope (6), have out, close the middle bolster (7) of device, through beam (8), gas valve (9), binding bolt members such as (10), the both sides that it is characterized in that the strut (2) at single rope grab are installed 3-4 independently small rubber air bag (3) respectively, big rubber pneumatic bag (5) is installed on the both sides base plate of bucket body (4), have drainage opening on bucket body (4) side plate, available binding bolt (10) is fixed on strut (2) to air bag, on the bucket body (4), float over the degree of depth in the water with the single rope grab of how much regulating of air bag quantity increase and decrease and charge air.
2. single rope grab according to claim 1 is characterized in that, described deck beam (1), strut (2), bucket body (4) etc. can be selected the lighter high-strength engineering plastic of deadweight for use, example: the PBTB/PETB material.
3. single rope grab according to claim 1 is characterized in that, has drainage opening on described bucket body (4) side plate.
