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: [0001] The invention relates to the technical field of underwater salvage machinery, in particular to an underwater salvage grab, which is equipped with a floating crane and is mainly used for salvaging underwater scrap steel and sunken ships, and can salvage up to 250 tons of scrap steel at one time. Background technique: [0002] At present, the traditional shipwreck salvage techniques include the following methods: buoyancy salvage, floating dock salvage, disintegration salvage, underwater blasting, grab salvage, etc. The previous salvage grab only had a balance beam, and the opening and closing wire ropes were rooted in the bucket. The head assembly or the center beam assembly, and there are multiple opening and closing wire ropes, so the above method has the following disadvantages: 1. Poor stability in the air; 2. The wire rope winding system is complicated, and the force on the wire rope is uneven; 3. The installation method of bucket teeth Not easy t...
