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
The present invention relates to cutter suction dredger, particularly relate to a kind of mounting method of cutter suction dredger reamer beam length axis hole twisted branch frame.
Background technology
Cutter suction dredger is a kind of static dredge boat, is widely used in harbour, waterway dredging and Dredger Filling Engineering.Dredge boat is equipped with reamer as excavating tools, earth is inhaled into after cutting; And the crossbeam it being installed reamer is reamer beam.
For ensureing installation accuracy, current cutter suction dredger, the axis hole of reamer beam needs to produce in production scene, first twisted point delimited to reamer beam, and then on-the-spot bore hole is carried out to twisted point, also need in the process to be accompanied by special frock tool and the mate-assist of dummy shaft, just can complete the installation of cutter suction dredger.But this kind of mode production cycle is long, inefficiency, be difficult to meet modern high efficiency requirement.
Summary of the invention
The present invention aims to provide a kind of mounting method of cutter suction dredger reamer beam length axis hole twisted branch frame, to simplify the installation work of cutter suction dredger, shortens the production cycle and increases work efficiency.
The mounting method of cutter suction dredger reamer beam length axis hole twisted branch frame of the present invention, comprises the following steps:
A, twisted point seat to be rule, mark horizontal center line, longitudinal centre line and located lateral line respectively;
B, general section of shipbody to be rule, mark horizon, rib bit line and located lateral line respectively;
C, lifting twisted point seat, hang on twisted point seat on general section of shipbody and position, align respectively with horizon, rib bit line and located lateral line;
D, symmetrical welding is carried out to the both sides of twisted point seat simultaneously;
After E, twisted point seat install hull, then twisted axis and strand lid are installed.
The mounting method of cutter suction dredger reamer beam length axis hole twisted branch frame of the present invention, twisted point seat is the supporting seat of reamer beam twisted axis, by the setting of twisted point seat, can carry out prefabricated to reamer beam, thus remove the drawback of on-the-spot bore hole installation from, effectively can shorten the production cycle, increase work efficiency; Meanwhile, in the process of installing at the scene, considerably reduce the use needs of auxiliary mould, task complexity can be reduced and coordinate difficulty; Reamer beam prefabricated without the need to using dummy shaft to carry out secondary process, reduces difficulty of processing and cost of production.Twisted point seat marks respectively horizontal center line, longitudinal centre line and located lateral line, three lines carry out positioned in alignment with the horizon on general section of shipbody, rib bit line and located lateral line respectively, can ensure the precision of installing; The setting of the cross bar inside twisted point seat, then can control the verticality in installation process.

Detailed description of the invention
A mounting method for cutter suction dredger reamer beam length axis hole twisted branch frame, comprises the following steps:
A, twisted point seat to be rule, mark horizontal center line, longitudinal centre line and located lateral line respectively;
B, general section of shipbody to be rule, mark horizon, rib bit line and located lateral line respectively;
C, lifting twisted point seat, hang on twisted point seat on general section of shipbody and position, align respectively with horizon, rib bit line and located lateral line;
D, twisted point seat is welded on general section of shipbody;
After E, twisted point seat install hull, then twisted axis and strand lid are installed.
As shown in Figure 1, reamer beam 4 has major axis hole 5, twisted point seat 1 is installed on reamer beam length axis hole place, and one end of twisted axis is fixed on twisted point seat.
In steps A, in twisted point seat both sides, each vertical two cursors, get phase co-altitude respectively with laser, rule as the benchmark of welding flatness at structure of an essay level measurement device of contour cursor.By the setting of contour cursor, and level measurement device level of control degree, ensure the installation accuracy of twisted point seat.
After step C completes, install a cross bar in order to ceiling hammer additional at twisted point seat medial surface, thus control its installation verticality.As shown in Figure 2,3, install a cross bar 2 in order to ceiling hammer 3 additional at the medial surface of twisted point seat 1, this cross bar can be an angle steel, and it is easy and with low cost that it is drawn materials.
In step D, symmetrical welding is carried out to the both sides of twisted point seat simultaneously.Construct in the both sides of twisted point seat simultaneously, while guaranteeing alignment accuracy, greatly can reduce the impact that deflection brings, improve installation accuracy further.On the other hand, the welding of twisted point seat should adopt little welding bead, the mode of segmentation skip welding is carried out welding, and welding bead is uniformly distributed, and avoids too much causing axle center to offset in the built-up welding of same position.
In step e, after twisted point seat installs hull, coordinated the installation site of left and right ship side by the cushion block of now joining.Pad thickness by now joining decision, and and carry out intermittent weld between twisted point seat; Preferably, ship side two shaft concentricity differences in left and right are made to be no more than 5mm by cushion block.
The diameter of strand lid and twisted point base inner surface, need now to join according to the real size of bearing outer ring in a pre-installation, interference is about 0.02mm; Forging shaft is now joined and fine finishining axle external diameter and seal groove by oscillating bearing internal diameter size, and interference is about 0.02mm.
