Abstract

The invention provides a processing and mounting technology for a cutter ladder of a cutter suction dredger. The processing and mounting technology comprises the following steps of dividing the cutterladder into four large segments, namely a cutter ladder head, a cutter ladder main body part, a cutter ladder tail and a cutter motor compartment, and reserving allowance of 30 mm at a segmented combined part between every two parts; arranging adjustable moulding beds at the bottom of the cutter ladder main body part; closing the cutter ladder head with the cutter ladder main body part; closing the cutter ladder tail with the cutter ladder main body part; closing the cutter ladder motor compartment with the main body part and the tail; and mounting a cutter ladder main bearing seat, a maintenance bearing block, a navigation locking device and a lifting lug. The processing and mounting technology provided by the invention has the beneficial effect that the aim of high installation precision of the cutter ladder configured on the cutter suction dredger is achieved.

Description

technical field [0001] The invention relates to the technical field of ship dredging equipment, in particular to a process for processing and installing a cutter bridge frame of a cutter suction dredger. Background technique [0002] The cutter bridge of a large cutter suction dredger is located at the stern of the ship. The cutter bridge is rotated around the main shaft through the lifting operation of the winch, so that the cutter bridge enters or leaves the working position, and the bearing is connected to the main hull. At the working position, the rock digging operation is realized by driving the reamer head to rotate. In the working state, the reamer bridge not only has to be raised and lowered around the fulcrum, but also must bear the severe vibration generated when the reamer head rotates to dig rock, which puts forward higher requirements on the manufacturing accuracy of the reamer bridge. As a key component, the reamer bridge has the characteristics of complex st...
