Abstract
The invention discloses an underwater salvage grab bucket. The underwater salvage grab bucket is characterized by comprising a weight balance beam (1) and an opening-closing balance beam (2), wherein a bucket head assembly (3) is arranged under the weight balance beam (1), and the bucket head assembly (3) is connected with the weight balance beam (1) through a chain; the bucket head assembly (3), a middle beam assembly (4), a supporting rod assembly (5) and a bucket body (6) are connected with each other through pin shafts, and can relatively rotate; the opening-closing balance beam (2) is connected with a bucket head pulley block (8) and a middle beam pulley block (9) through an opening-closing steel wire rope (7) to be formed into a steel wire rope winding system; the bucket head pulley block (8) and the middle beam pulley block (9) are respectively fixed on the bucket head assembly (3) and the middle beam assembly (4) through a pulley shaft; and a bucket tooth seat (10) of the bucket body (6) is provided with a bucket tooth (11) through a screw bolt. The underwater salvage grab bucket integrates the smash with the salvage into a whole, has good air stability, can easily change the bucket tooth and the steel wire rope, is suitable for raising a sunk ship from the bottom of the sea, has great excavating capability, can laniate a steel board of the sunk ship, greatly improves the efficiency for raising the sunk ship from the bottom of the sea, and improves the economic benefit thereof.
Description
Technical field:
The present invention relates to the underwater salvage field of mechanical technique, is a kind of underwater salvage grab bucket specifically, is provided on the crane barge and uses, and is mainly used in to salvage steel scrap and shipwreck under water, once can salvage 250 tons of steel scraps at most.
Background technology:
At present, traditional wreck salvage technology comprises following method: buoyancy overshot, floating drydock salvaging, disintegrate salvage method, underwater blasting method, grab bucket salvaging etc., salvage grab bucket in the past has only an equalizing bar, opening and closing steel rope is to take root on bucket head assembly or central sill assembly, and have many to open and close steel rope, thereby there is following shortcoming in aforesaid way: 1, aerial poor stability; 2, steel cable winding system complexity, the steel rope discontinuity; 3, the bucket tooth mounting means is difficult for changing; 4, fishing process labour intensity big, dangerous big, refloating operation is made slow progress, complicated operation, efficient are low.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and provide a kind of underwater salvage grab bucket, integrate broken, salvage, mainly solve the aerial poor stability of existing salvage grab bucket, steel rope discontinuity, bucket tooth install be difficult for changing, labour intensity is big, dangerous big, problem such as refloating operation is made slow progress, complicated operation, efficient are low.
In order to achieve the above object, the present invention is achieved in that underwater salvage grab bucket, its special character is that it comprises gravitational equilibrium fine strain of millet and opens and closes two equalizing bars of equalizing bar, below gravitational equilibrium fine strain of millet, establish the bucket head assembly, the two connects by chain, be used for promoting grab bucket, safeguard the aerial stability of grab bucket; Be linked together by bearing pin between bucket head assembly, central sill assembly, strut assembly, the bucket body, can relatively rotate; Open and close equalizing bar and be linked together with a bucket assembly pulley, central sill assembly pulley, form steel cable winding system, be used for the switching of skip body by opening and closing steel rope; A bucket assembly pulley, central sill assembly pulley are separately fixed on bucket head assembly, the central sill assembly by sheave shaft, and pulley can rotate on sheave shaft; On the bucket tooth seat of bucket body, bucket tooth is installed, can be made things convenient for the dismounting of bucket tooth by bolt.
Underwater salvage grab bucket of the present invention, the steel rope of its described steel cable winding system are single.
Compared with the prior art underwater salvage grab bucket of the present invention has outstanding substantive distinguishing features and marked improvement: 1, owing to increase bucket tooth on bucket body, integrate broken, salvage, realize the salvaging of large-scale wreck in the grab bucket field; 2, adopt two balance fine strain of millet structures of gravitational equilibrium beam and switching equalizing bar, having solved grab bucket effectively and having used the restriction of height, and having reduced the stressed of steel rope, make steel rope stressed more even; 3, bucket tooth and bucket tooth seat adopt bolted connection, are easy to change; 4, the steel rope of grab bucket steel cable winding system only is single, and its design is succinct, is easy to change rope.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of steel cable winding system of the present invention.
The specific embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe underwater salvage grab bucket of the present invention in detail.
Embodiment 1, referring to Fig. 1,2, is processed into gravitational equilibrium fine strain of millet 1 and opens and closes equalizing bar 2, and bucket head assembly 3 is installed below gravitational equilibrium fine strain of millet 1, and the two connects by chain, is used for promoting grab bucket, safeguards the aerial stability of grab bucket; Bucket head assembly 3 connects with strut assembly 5 by bearing pin, strut assembly 5 connects with bucket body 6 by bearing pin, bucket body 6 connects with central sill assembly 4 by bearing pin, makes between bucket head assembly 3, central sill assembly 4, strut assembly 5, the bucket body 6 to be linked together by bearing pin, can relatively rotate; A bucket assembly pulley 8, central sill assembly pulley 9 are separately fixed on bucket head assembly 3, the central sill assembly 4 by sheave shaft, and pulley can rotate on sheave shaft; To open and close equalizing bar 2 again is linked together with a bucket assembly pulley 8, central sill assembly pulley 9 by opening and closing steel rope 7; Open and close steel rope 7 and take root opening and closing on the equalizing bar 2, form steel cable winding system, steel rope is single, is used for the switching of skip body; The bucket tooth seat 10 that is welded on the shear blade oralia of bucket body 6 is installed bucket tooth 11 by bolt on bucket tooth seat 10; Gravitational equilibrium beam 1 and switching equalizing bar 2 finally are separately fixed on the eave tile of crane barge.
Underwater salvage grab bucket of the present invention is by a bucket assembly pulley, central sill assembly pulley and open and close equalizing bar and steel rope composition winding system, provides enlargement ratio by the steel rope canoe, provides digging force to grab bucket.This grab bucket is when operation, the gravitational equilibrium beam is motionless, the switching equalizing bar of loweing makes the bucket body of grab bucket rely on the weight of central sill assembly to open, and utilizes high-intensity bucket tooth is housed on the bucket body, can be when salvaging a sunken ship, slip into the dark seabed of hundreds of rice, pierce through the shipwreck deck, promote the switching equalizing bar then and make the skip body closure, thereby tear the deck, under water from it being salvaged; The extracting moment of underwater salvage grab bucket is big, and grasp force can reach 3000 tons when closed, the bucket tooth of both sides under the effect of this power, can be easily with the hull partial penetration and tear up, finally salvage by this grab bucket again.
