Embodiment Construction

[0015] A method for installing a cutter beam long axis hole cutter support of a cutter suction dredger, comprising the following steps:

[0016] A. Mark the twist point seat, and draw the horizontal centerline, longitudinal centerline and horizontal positioning line respectively;

[0017] B. Carry out lines on the general section of the hull, draw horizontal lines, rib position lines and transverse positioning lines respectively;

[0018] C. Hoist the hinge point seat, hoist the hinge point seat on the general section of the hull for positioning, and align with the horizontal line, rib position line and transverse positioning line respectively;

[0019] D. Weld the twist point seat to the general section of the hull;

[0020] E. After installing the twist point seat on the hull, install the twist shaft and the twist cover.

[0021] like figure 1 As shown, there is a long axis hole 5 on the reamer beam 4, and the reaming point seat 1 is installed at the long axis hole of the...

Abstract

The invention provides a cutter suction dredger reamer beam long-axle-hole reaming support mounting method. Lines are scribed on a reaming point base and a ship hull block respectively, then scribed line alignment mounting is conducted on the reaming point base and the ship hull block, the perpendicularity of the reaming point base is controlled in the mounting process, the two sides of the reaming point base are symmetrically welded when the reaming point base is welded, and a reaming shaft and a reaming cover are arranged after the reaming point base is arranged on a ship hull. According to the method, a reamer beam can be prefabricated due to arrangement of the reaming point base, the defect of field boring and mounting is overcome, the production cycle can be shortened effectively, and working efficiency is improved; meanwhile, the requirement for using auxiliary tools is reduced greatly, the machining difficulty is lowered, no dummy shaft is needed to conduct auxiliary machining, and the machining difficulty and production cost are lowered.

Description

technical field [0001] The invention relates to a cutter suction dredger, in particular to a method for installing a cutter beam long axis hole cutter bracket of a cutter suction dredger. Background technique [0002] Cutter suction dredger is a kind of static dredger, which is widely used in port, waterway dredging and reclamation projects. The dredger is equipped with a reamer as an excavating tool, so that the soil is sucked after cutting; and the beam on which the reamer is installed is the reamer beam. [0003] In order to ensure the installation accuracy, the current cutter suction dredger, the shaft hole of the cutter beam needs to be produced on the production site. In addition, special tooling tools and auxiliary cooperation with dummy shafts are required to complete the installation of the cutter suction dredger. However, this method has a long production cycle and low efficiency, and it is difficult to meet the modern high-efficiency requirements. Contents of...
