Abstract

The invention provides a grab dredger and a lifting mechanism of a grab machine of the grab dredger. The lifting mechanism of the grab machine comprises one or more sets of driving units, wherein each driving unit comprises a motor, a transmission, a first coiling block and a second coiling block, the input end of the transmission is connected with a transmission shaft of the motor, a rotating shaft of the first coiling block is connected with the output end of the transmission, the block body of the second coiling block is connected with the rotating shaft of the first coiling block, and the first coiling block and the second coiling block are coaxially driven by the motor through the transmission. The mounting space of the whole lifting mechanism can be reduced, and single-drive, large-span and large-torque requirements can be met.

Description

Technical field [0001] The invention relates to a grab bucket dredger and its grab bucket lifting mechanism. Background technique [0002] In the past ten years, the scale of offshore dredging and filling projects has become larger and larger, and the dredging market has increasingly higher requirements for the efficiency, cost, energy saving and emission reduction of dredging equipment, and dredging companies’ demand for large-scale dredging equipment has also increased. The more urgent it is, all countries in the world are devoting themselves to the research and development of a new generation of large dredgers in order to occupy the dredging market. [0003] For grab dredgers, the grab lifting mechanism is an important part. reference figure 1 , The lifting mechanism of the grab machine in the prior art mainly includes a motor 11, a transmission 12 and a reel 13, wherein the motor 11 is connected to the input end of the transmission 12 through a coupling 14, and the output end ...
