Description
Technical field
The present invention relates to cutter suction dredger, more particularly to a kind of cutter suction dredger reamer beam length axis hole twisted branch frame
Installation method.
Background technology
Cutter suction dredger is a kind of static dredger, is widely used in harbour, waterway dredging and Dredger Filling Engineering.Dredge
Soil is set to be inhaled into after cutting as digging tool equipped with reamer on ship；And the crossbeam for installing reamer thereon is reamer beam.
To ensure installation accuracy, current cutter suction dredger, the axis hole of reamer beam needs to be produced in production scene,
Twisted point first delimited to reamer beam, then pair twist point carries out live bore hole again, also needs to be accompanied by special frock tool in the process
With the mate-assist of dummy shaft, the installation of cutter suction dredger could be completed.It is difficult but this kind of mode production cycle is long, inefficiency
To meet the high efficiency requirement of modernization.
The content of the invention
The present invention is intended to provide a kind of installation method of cutter suction dredger reamer beam length axis hole twisted branch frame, is inhaled with simplifying to twist
The installment work of formula dredger, shortens the production cycle and improves operating efficiency.
The installation method of cutter suction dredger reamer beam length axis hole twisted branch frame of the present invention, comprises the following steps：
A, to twisted point seat rule, horizontal center line, longitudinal centre line and located lateral line are marked respectively；
B, general section of shipbody is rule, horizontal line, rib bit line and located lateral line are marked respectively；
C, lifting twisted point seat, twisted point seat is hung on and positioned on general section of shipbody, respectively with horizontal line, rib bit line and horizontal stroke
Alignd to position line；
D, while to twisted point seat both sides carry out symmetrical welding；
E, twisted point seat are installed after upper hull, then are installed twisted axis and twisted lid.
The installation method of cutter suction dredger reamer beam length axis hole twisted branch frame of the present invention, twisted point seat is that reamer beam is twisted
The support base of axle, can be prefabricated to the progress of reamer beam by the setting of twisted point seat, so that remove the drawbacks of live bore hole is installed from, can
Effectively shorten the production cycle, improve operating efficiency；Meanwhile, during installing at the scene, considerably reduce auxiliary mould
Using needs, task complexity can be reduced and coordinate difficulty；The prefabricated of reamer beam carries out secondary process, drop without using dummy shaft
Low difficulty of processing and production cost.Horizontal center line, longitudinal centre line and located lateral line, three are marked respectively on twisted point seat
Line carries out positioned in alignment with the horizontal line on general section of shipbody, rib bit line and located lateral line respectively, ensure that the precision of installation；
The setting of cross bar on the inside of twisted point seat, then can control the perpendicularity in installation process.
Brief description of the drawings
Fig. 1 is the mounting structure schematic diagram of twisted point seat.
Fig. 2 is the structural representation of twisted point seat.
Fig. 3 is the sectional view of twisted point seat.
Embodiment
A kind of installation method of cutter suction dredger reamer beam length axis hole twisted branch frame, comprises the following steps：
A, to twisted point seat rule, horizontal center line, longitudinal centre line and located lateral line are marked respectively；
B, general section of shipbody is rule, horizontal line, rib bit line and located lateral line are marked respectively；
C, lifting twisted point seat, twisted point seat is hung on and positioned on general section of shipbody, respectively with horizontal line, rib bit line and horizontal stroke
Alignd to position line；
D, by twisted point seat be welded on general section of shipbody；
E, twisted point seat are installed after upper hull, then are installed twisted axis and twisted lid.
As shown in figure 1, being provided with long axis hole 5 on reamer beam 4, twisted point seat 1 is installed at reamer beam length axis hole, the one of twisted axis
End is fixed on twisted point seat.
In step A, in each vertical two cursors in twisted point seat both sides, identical height is got respectively with laser, in contour cursor
One level measurement device of a structure of an essay rule as the benchmark of welding plane degree.Pass through the setting of contour cursor, and level
Measurement apparatus controlled level degree, it is ensured that the installation accuracy of twisted point seat.
After the completion of step C, install one additional in twisted point seat medial surface and be used to the cross bar of ceiling hammer, hung down so as to control it to install
Straight degree.As shown in Figure 2,3, a cross bar 2 for being used to ceiling hammer 3 is installed additional in the medial surface of twisted point seat 1, the cross bar can be one
Angle steel, its materials are easy and with low cost.
In step D, while carrying out symmetrical welding to the both sides of twisted point seat.Carry out constructing simultaneously in the both sides of twisted point seat,
While ensuring alignment accuracy, the influence that deflection is brought can be greatly reduced, installation accuracy is further improved.The opposing party
Face, the welding of twisted point seat preferably carries out welding by the way of small welding bead, segmentation skip welding, and is uniformly distributed welding bead, it is to avoid same
One position built-up welding is excessive and causes axle center to offset.
In step E, twisted point seat is installed after upper hull, coordinates the installation site of left and right ship side by the cushion block now matched somebody with somebody.Pad
Block thickness is determined by now matching somebody with somebody, and carries out intermittent weld between twisted point seat；Preferably, make ship side two axles in left and right concentric by cushion block
Degree difference is no more than 5mm.
The diameter of lid and twisted point base inner surface is twisted, needs according to the actual size of bearing outer ring now to be matched somebody with somebody in a pre-installation, mistake
It is full of about 0.02mm；Forging shaft is now matched somebody with somebody by oscillating bearing internal diameter size and finishes axle external diameter and seal groove, interference about 0.02mm.
