Rock cracking device of cutter suction ship

Abstract

The invention discloses a rock cracking device of a cutter suction ship. The device comprises a cutter suction ship body, wherein a cutter head bridge frame is hinged to the cutter suction ship body; a rocker arm support is arranged below the cutter head bridge frame; a rock cracking device frame is arranged at the front end of the rocker arm support; the rear end of the rocker arm support is hinged to the lower end of the cutter head bridge frame; a rocker arm support angle adjusting hydraulic cylinder is connected between the upper end of the rocker arm support and the back surface of the cutter head bridge frame and used for adjusting the angle of the rocker arm support; and the top of the lower end of the cutter head bridge frame is provided with a cutter head. The device has the advantages that the rock cracking device is arranged at the front position of the cutter head on an existing cutter suction ship, transverse thrust is generated on the cutter head bridge frame due to the fact that the counter-resisting force is generated on the contact surface with the ground when the cutter head rotates in operation, and a cutter tooth arm, a rock cracking cutter or cutter teeth is driven by the rock cracking device to crush reefs by utilizing the thrust and high-frequency vibration; and the device has the advantages of high rock cracking efficiency, energy conservation, environment friendliness and the like.

Description

technical field [0001] The invention relates to the technical field of underwater rock and soil loosening, and relates to a cutter suction ship rock cracking device. Background technique [0002] At present, in the construction of underwater reef blasting projects at home and abroad, there are mainly the following ways to deal with various reefs: [0003] (1) Explode method with dynamite tree; Explosive is placed on reef surface and detonates, and its shortcoming explosive consumption is big, and efficiency is low; [0004] (2) Drilling charge blasting method: use a professional drill ship to drill holes in underwater reefs, and after drilling, put explosives into the holes and then detonate. The disadvantages are complicated operation, high construction cost, and pollution; [0005] (3) Hammering method: the heavy-duty impact hammer is lifted from the reef surface by a crane to release at a certain height, and the impact hammer freely falls to impact the reef surface and s...

Problems solved by technology

[0003] (1) Explode method with dynamite tree; Explosive is placed on reef surface and detonates, and its shortcoming explosive consumption is big, and efficiency is low;

[0004] (2) Drilling charge blasting method: use a professional drill ship to drill holes in underwater reefs, and after drilling, put explosives into the holes and then detonate. The disadvantages are complicated operation, high construction cost, and pollution;

[0005] (3) Hammering method: the heavy-duty impact hammer is lifted from the reef surface by a crane to release it at a certain height, and the impact hammer free-falls to impact the reef surface and crush the reef surface. Its disadvantages are difficult to control and low efficiency.
