Abstract

The invention relates to a steel pile hoisting system for a cutter suction dredger. The steel pile hoisting system comprises a connecting base, wherein the connecting base is mounted on a dredger body. The connecting base is connected with a first suspension cable and a second suspension cable. A first jacking oil cylinder and a second jacking oil cylinder are mounted at the two sides of the connecting base. Two pile clamping devices are further mounted on the dredger body, wherein the two pile clamping devices are arranged oppositely. A first steel pile is arranged in the pile clamping deviceat the left side, and a second steel pile is arranged in the pile clamping device at the right side. A first ascending-and-descending guide wheel is mounted at the top end of a piston rod of the first jacking oil cylinder, and a second ascending-and-descending guide wheel is mounted at the top end of a piston rod of the second jacking oil cylinder. The steel pile hoisting system further comprisesan inner side ascending-and-descending oil cylinder, wherein the bottom end of a piston rod of the inner side ascending-and-descending oil cylinder is provided with a linkage wheel carrier. A first linkage guide wheel and a second linkage guide wheel are mounted on the linkage wheel carrier. The middle of the first suspension cable bypasses the first linkage guide wheel and the rear end of the first ascending-and-descending guide wheel and is connected to the top of the first steel pile, and the middle of the second suspension cable bypasses the second linkage guide wheel and the rear end ofthe second ascending-and-descending guide wheel and is connected to the top of the second steel pile.

Description

technical field [0001] The invention belongs to the technical field of dredging construction, in particular to a steel pile lifting system of a cutter suction dredger. Background technique [0002] The positioning pile system is installed on the cutter suction dredger. The function of the positioning pile system is to fix the cutter suction dredger, that is, after the ship is moored in place, the falling steel pile is inserted into the soil at the bottom of the water to anchor the construction ship. The fixed construction ship will carry out dredging construction in a certain area. The construction ship also needs to be equipped with a driving system for the steel piles. Generally, the steel piles (that is, the positioning piles) need to be placed horizontally when the ship is in a sailing state, and they need to be kept vertical when the ship is berthed in place and during the entire construction process. , the above drive system needs to meet the needs of steel pile state...
