Description
Technical field
The present invention relates to a kind of cranes, can be turned over backward more particularly, to a kind of arm support applied on offshore engineering ship
Turn the floating crane shelved.
Background technology
Currently, floating crane（Also known as crane barge）It is one of essential important device of offshore engineering ship, with ocean
The continuous development of engineering, the weight and height of marine module constantly become larger, and the requirement to floating crane is also higher and higher, arm support
Main stressed member length as floating crane is more and more longer and its own weight is also increasingly heavier.Therefore, floating
Crane needs arm support reduction height of falling during hull towage, so as to the height that lowers the center of gravity, increases stability and change
The stressing conditions of structure；
For this purpose, conventional operation on the sea workboat uses the floating crane of Full Rotary structure；But for full circle swinging
For the floating crane of formula structure, one is at high price, and two need the larger deck space to carry out mounting arrangements, undoubtedly into
One step improves its cost, is unfavorable for reducing engineering cost, and the floating crane of Full Rotary structure is limited by its structure
Form causes its height of C.G. higher, when being unfavorable for towage, stability when construction operation；Therefore, there is an urgent need for one kind to ensure to apply
The more cheap offshore engineering to have more the market competitiveness of price floating crane structure peculiar to vessel while working medium amount.
Invention content
The purpose of the present invention is to overcome the above shortcomings and to provide shelve single arm support lifting after a kind of low-cost floating
Machine.
The object of the present invention is achieved like this：
Single arm support crane is shelved after a kind of floating, it includes to be installed on hull that single arm support crane is shelved after the floating
On bearing and A cabinet frames, the bottom of an arm support be articulated on the top of bearing；
One end of one end and overturning auxiliary rod two for overturning auxiliary rod one is articulated on bearing jointly, the overturning auxiliary rod
It is to have tense wire rope between one other end and the other end for overturning auxiliary rod two, the top of the overturning auxiliary rod one and arm support
It is to have main hoist rope between portion, pulley blocks is installed on the overturning auxiliary rod two, are equipped on the bearing or hull
Fixed pulley, be installed on hull overturning winch on overturning steel wire rope after pulley blocks on fixed pulley；
It is provided with the rest stand placed for arm support at the top of the A cabinet frames, pulley blocks are installed on the A cabinet frames, it is described
The variable amplitude rope on span winch on hull is lain in through pulley blocks on arm support.
Single arm support crane, the overturning auxiliary rod one, overturning auxiliary rod two and tension are shelved after a kind of floating of the present invention
Steel wire rope constitutes a triangular structure.
Single arm support crane is shelved after a kind of floating of the present invention, lifting hook pulley is installed on the mounting plate at the top of the arm support
Group one and lifting hook pulley group two, main hoist rope rope in the hoister winch group is through the pulley on hull, arm support bottom
After pulley turns to, the pulley at the top of arm support to arm support returns again to be divided into two main hoist ropes, two masters through mounting plate
Hoist rope is connected to suspension hook one and suspension hook two after lifting hook pulley group one and lifting hook pulley group two respectively；Suspension hook one and suspension hook
Two hooks are placed on overturning auxiliary rod one.
Single arm support crane is shelved after a kind of floating of the present invention, rotary cable storehouse is also equipped on hull, it is described rotary
Cable storehouse includes the multiple roller supports being installed on hull, and scroll wheel is equipped on the roller support, the scroll wheel
Wheel face fits on the bottom surface of rotary disk, and chain is set on the side surface circumference of the rotary disk, is provided with by the rotary disk
The drive shaft of multiple drive motors, the drive motor is vertically arranged, and gear is set in the drive shaft of drive motor, described
Gear is meshed with chain；Storehouse cage for storing cable is installed on the rotary disk；One is provided with by the rotary disk
One end of support, support frame as described above, a back twist frame being laterally arranged is articulated on supporting rack.
Single arm support crane is shelved after a kind of floating of the present invention, an arc guide ribs are provided on support frame as described above, it is described
It is slideably positioned in the middle part of back twist frame in the arc guide ribs.
Single arm support crane is shelved after a kind of floating of the present invention, when arm support is shelved on the rest stand of A cabinet frames, in etc.
Wait for state；
When arm support leaves during A cabinet frames turn to plumbness, the suspension hook on main hoist rope hooks overturning auxiliary
Bar one, overturning winch start, to which arm support is turned to plumbness by tense wire rope and main hoist rope；
When arm support continues overturning, span winch starts the state of control arm support, and the suspension hook on main hoist rope is detached from
It overturns auxiliary rod a pair and plays hanging object progress lifting operation.
Compared with prior art, the beneficial effects of the invention are as follows：
Present invention overturning is simple in structure, cheap, and convenient for being reequiped to existing hull to reduce cost, therefore
Help to improve its market competitiveness；Meanwhile using rear convertible structure after, advantageously reduce its whole height of C.G., increase
Its stability.
