Figure 11 shows the general arrangement of cutter suction dredger gantry Integral transporting according to the present invention.
Gantry integral shift scheme according to the present invention is coupled interim trolley with hoist engine mode of traction, by gantry
It is installed in Integral transporting in orbit to main hull stern fluting, is achieved in gantry internal unit and installs and guarantee in advance
Gantry integral installation precision improves production efficiency, shortens construction period.
According to parameters such as gantry weight, sizes, certain amount trolley is set below gantry support construction.Traction side setting 2
2 hoist engines are arranged in platform hoist engine, insurance side, and hoist engine is fixed on harbour using steel plate press-fitting double recipe formula, draws total root and hang
Ear is welded on dredger main hull, is insured total root lifting lug and is welded on the steel plate of press-fitting weight.When displacement, 2 elevator machine travels,
2 hoist engine insurances, it is desirable that lowest speed, synchronous, crawl operates when reaching installation site fastly.
As shown in figure 11,6 400t trolleys are arranged in an embodiment according to the present invention below gantry support construction,
2 hoist engines are arranged in traction side, and 2 hoist engines are arranged in insurance side.4 hoist engines are fixed in such a way that steel plate is press-fitted pouring weight
In on harbour, the clump weight weight of every hoist engine is more than or equal to 50 tons.Traction is always welded on dredger main hull with lifting lug
On 37# rib position, insurance is always welded on the steel plate of press-fitting pouring weight with lifting lug, and clump weight weight is more than or equal to 150 tons.Gantry is practical
Translocation distance is 30.75 meters.Up and down amount trimmed and left and right amount trimmed of the gantry in the final position installation of main hull stern fluting
Within 20mm.
The specific movement process for carrying out movement using gantry movement technical solution of the present invention is as follows:
Step 1: in tooling, track, equipment conveying to dock, and clear up shift paths.
Step 2: scribing line, is laid with track, track is fixed, and due to dock bottom injustice, and trolley force request is stringenter, is needed
By rail levelling, upper surface need to be in same level.
Step 3: hoist engine is put in place, total root lifting lug is welded, counterweight pressing block is in place.
Step 4: placing 400t trolley, the dismounting of trolley motor is placed into gantry support construction.
Step 5: installing shackle, coaster, wearing traction and insurance side wirerope.
Step 6: needing to carry out gantry examination top operation before movement, to check whether cause portal structure broken in gantry movement
Bad or tooling unstability.
Step 7: 400t trolley jacks up, and safety block is placed, starts to slide.
Step 8: sliding is in place.
Step 9: front and back is finely tuned, trolley removes safety block and finely tunes up and down, until installing successfully.
Track laying
It is laid with track in dock, track uses H316, and 70 meters of track overall length, track width 600mm.Orbit centre line-spacing
Minimum spacing from two sides docking block is not less than 40mm.
In order to reduce the resistance generated when gantry traction movement, the flatness to track, gap are needed in track laying
It is controlled with difference in height.
Track is set to be guaranteed at same level.The flatness of track reaches in ± 5mm.The diagonal error of track ±
10mm。
Height is crossed and surveyed using laser Lycra, and rail linearity degree and trolley plate thickness are met the requirements.
Figure 12 shows track laying schematic diagram.
The placement of hoist engine and total root lifting lug
Figure 13 shows the layout drawing of hoist engine and lifting lug, and 1 is hoist engine in figure, and 2 always hang for insurance with lifting lug, 3 for traction
Ear, 4 be traction always with lifting lug.
4 hoist engines are welded on the steel plate for being placed with clump weight, and clump weight weight is more than or equal to 50 tons.
Traction lifting lug is welded on gantry；Total root lifting lug is drawn to be welded on the position of hull 37# rib position.
Insurance lifting lug is welded in gantry support construction, is insured total root lifting lug and is welded on the steel plate for being placed with clump weight,
Clump weight weight is more than or equal to 150 tons.
The installation of 400 tons of trolleys
Figure 14 shows trolley scheme of installation.
6 400t trolleys are arranged in preferred embodiment according to the present invention below gantry support construction.2 components of trolley point
Designated position is not slid onto from 2 tracks.Trolley 1 and 2 is located at the position A13 of gantry support construction, and trolley 3 and 4 is located at bridge
At the position A7 of frame support structure, trolley 5 and 6 is located at the position A2 of gantry support construction.
In order to avoid the interference of motor and the gantry support of trolley, motor is disassembled from trolley and is placed into gantry
On Support Position and increase with the hydraulic oil pipe for meeting length requirement.
Trolley slides onto designated position from the tail portion of track.Connect trolley and gantry support construction by trolley connector
It connects.Trolley is linked together by the attachment base bottom plate of bolt and trolley connector.The attachment base top plate of trolley connector passes through
Welding welds together with gantry support construction.
Gantry integral shift
Figure 11 shows the general arrangement of cutter suction dredger gantry Integral transporting according to the present invention.
When gantry Integral transporting, drawn using 2 12t hoist engines and 2 12t hoist engine insurances.
Wirerope wears coaster, and coaster is connected to traction lifting lug, insurance lifting lug, traction always with lifting lug and insurance always with lifting lug
On.
According to the distance between the gantry bottom surface of in-site measurement and track upper surface, trolley attachment base and connecting plate are installed,
400t trolley lifts 168mm simultaneously, has padded safety block and has prepared to shift later.
When displacement, by the traction of 2 rack winches and 2 insurance hoist engines, keep gantry whole with lowest speed along track
