Cutter suction dredger with reamer support lifting device

Abstract

The invention discloses a cutter suction dredger with a reamer support lifting device. The cutter suction dredger comprise a hull and a reamer support, wherein the hull comprises a deck and a bottom plate, and a reamer head is fixedly installed at the head of the reamer support; the cutter suction dredger further comprises the reamer support lifting device, the bottom of the lifting device is fixedly connected with the bottom plate, the top of the lifting device is rotationally connected with the tail of the reamer support, and a stretching device capable of lifting the tail of the reamer support is arranged between the top and the bottom of the lifting device; and the head of the reamer support is tied to one end of a steel wire rope in a suspended manner, and the other end of the steel wire rope is connected with a winch. The height of the tail and the height of the head of the reamer support are controlled through the stretching device, the winch and the steel wire rope separately,so that sludge above the minimum dredging depth can be cleaned away within a working angle range, the maximum dredging depth cannot be changed, and then the vertical operating range of the cutter suction dredger is enlarged; and meanwhile, operation is easy, and the structure is simple.

Description

technical field [0001] The invention relates to the field of dredgers, in particular to a cutter suction dredger with a reamer bracket lifting device. Background technique [0002] The cutter suction dredger is used for mud cleaning in the river and near the coast. The main part of the dredging is the reamer head, which is fixedly installed on the reamer bracket. The reamer bracket can rotate around a fixed axis at the tail to perform vertical dredging. Circular movement, the head of the reamer bracket moves up and down under the traction of the wire rope to realize the vertical movement of the reamer head between the maximum digging depth and the shallowest digging depth, and clean the silt at a certain depth in the water. The angle between the head and the water surface must be within a certain range of working angles in order to be able to clean the sludge normally. The maximum dredging depth of the cutter suction dredger is about 40m below the water surface, and the min...

AI Technical Summary

Problems solved by technology

The maximum dredging depth of the cutter suction dredger is about 40m below the water surface, and the minimum dredging depth is about 7m below the water surface. Therefore, it is impossible to carry out silt cleaning in places where the depth of sediment in the water is shallow, especially in rivers and coasts. and the silt that cannot be cleaned also affects the approaching operation of the dredger to the shore to a certain extent
