Abstract
The utility model discloses a kind of marine crane slewing tower, relate to marine crane manufacturing technology field, including being provided with the keel plate of installing hole, described keel plate is located at the top of cylinder, and the bottom welding of described cylinder is on flange；Described cylinder is provided with, in barrel, the vertical keel support plate that polylith is connected with described keel plate.Compared with prior art, this utility model can solve the aging problem with bolt shortening in service life of hydraulic line that existing marine crane slewing tower easily causes slew gear.
Description
Technical field
This utility model relates to marine crane manufacturing technology field, a kind of turret for marine crane
Body.
Background technology
Slewing tower, as the main part of crane, mainly includes tower body body, and this tower body body lower part is connected with base
Coordinating, its top is connected with tripod, and tripod is connected with arm；And by the slew gear being assemblied on slewing tower
Little gear engage with the gear wheel of pivoting support and do planetary motion, thus reach this main actions of crane rotation.Have one
Planting marine crane slewing tower as shown in Figure 1, this slewing tower includes that polylith is provided with the keel plate 03 of installing hole 02, polylith
Keel plate 03 interval is welded on base plate 01.In use there are the following problems for this marine crane slewing tower: 1,
The hydraulic line of slew gear and the bolt being connected with pivoting support are exposed on base plate, afloat high salt, hot environment
Under, easily cause that hydraulic line is aging and bolt shortens service life；2, slewing tower, the normal pressure of tripod and arm are just
Pressure then concentrates on same keel plate close positions.
Utility model content
The problem that this utility model is solved is to provide a kind of marine crane slewing tower, to solve the lifting of existing ocean
Machine slewing tower easily causes the aging problem with bolt shortening in service life of hydraulic line of slew gear.
In order to solve the problems referred to above, the technical solution adopted in the utility model is: this marine crane slewing tower bag
Including the keel plate being provided with installing hole, described keel plate is located at the top of cylinder, and the bottom welding of described cylinder is on flange；Described
Cylinder is provided with, in barrel, the vertical keel support plate that polylith is connected with described keel plate.
In above-mentioned marine crane slewing tower technical scheme, more specifically technical scheme it may also is that described cylinder in
Side bottom barrel is provided with winch erecting bed.
Further: described vertical keel support plate is two pieces, two pieces of described vertical keel support plates are respectively welded at described cylinder
On the barrel of body both sides.
Owing to have employed technique scheme, this utility model compared with prior art has the advantages that 1, empty
Between big, slew gear and slew gear pipeline and bolt are all arranged in cylinder, and maintainability is preferable；2, due to tripod
Being arranged on cylinder top, span winch is arranged in cylinder body bottom, and the elevation angle of variable-amplitude steel wire rope is less than existing elevation angle, steel
The row of cord restricts can more preferably, and the life-span also can be higher；3, this marine crane slewing tower passes through keel plate Stress Transfer at tower
On body cylinder, the normal pressure of tripod and the normal pressure of arm are respectively acting on two pieces of vertical keel support plates, make keel plate
Stress condition is more preferable.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing marine crane slewing tower.
Fig. 2 is the structural representation of this utility model embodiment.
Detailed description of the invention
The utility model is described in further detail for example below in conjunction with the accompanying drawings:
Marine crane slewing tower as shown in Figure 2 includes the keel plate 3 having installing hole 3-1, and keel plate 3 welds
At the top of cylinder 2, the bottom welding of cylinder 2 is on flange 1；The present embodiment cylinder 2 is provided with two pieces and keel plate 3 in barrel
The vertical keel support plate 3-2 being welded to connect, two pieces of vertical keel support plate 3-2 are respectively welded at the cylinder of the corresponding both sides of cylinder 2
On wall；Side bottom cylinder 2 barrel is welded with a winch erecting bed 4.
