Swing arm type crane barge for mounting wind power equipment
Technical field
The present invention relates to the equipment installation of a kind of shoal water zone and use derrick barge, be particularly useful for intertidal belt wind electric equipment installation derrick barge.
Background technology
When intertidal belt wind electric equipment is installed, each parts of aerogenerator need to be transported to the base position that is in intertidal zone fan, carry out again installation exercise.At present the movable hoisting equipment used of land is because of from great, the shallow special operation condition requirements such as the easy depression in sandy beach, intertidal zone and fluctuation tide that are difficult to satisfy of paddling.And conventional crane ship is darker because absorbing water, and the intertidal zone is its prohibited area, and nature can't set foot in.Therefore develop a kind of shallow draft, movably intertidal belt wind electric equipment to install with swing arm type crane barge be one of urgent need to solve the problem.
Summary of the invention
The object of the invention is to, provide a kind of intertidal belt wind electric equipment to install and use swing arm type crane barge, carry out the shoal water zone navigation by the vane wheel propeller that adopts the barge both sides, adopt the sled formula propelling unit of four jiaos of barges to carry out the position adjustment in more shallow zone, the again swing by swing arm type crane horn frame finally realizes the unloading of equipment components, the deck plane goods and materials are controlled, transport, on-the-spot installation.
Technical solution of the present invention is achieved in that
A kind of swing arm type crane barge for mounting wind power equipment, comprise and refute body, there is gantry jib in the central authorities of refuting body, gantry jib is comprised of left and right truss upright-column, truss crossbeam and pulley crossbeam, it is characterized in that: the lower end of left and right sides truss upright-column is hinged with the hinged-support of refuting on the body, and the top of left and right sides truss upright-column is connected with the forward and backward deck of refuting body respectively by forward and backward luffing mechanism; Two cover lifting mechanisms also are installed in the bottom of left and right sides truss upright-column, on the winch wherein steel rope are arranged, steel rope is walked around two groups of fixed pulley groups that are contained in the pulley crossbeam, and to drive two groups of lifting hook pulley groups vertically mobile; Vane type propelling unit and sled formula propelling unit then are housed respectively in the both sides of refuting body.
The two ends of described pulley crossbeam are flexibly connected with the fixedly hinge that is welded in left and right sides truss upright-column respectively.
Described front luffing mechanism is comprised of winch, pull bar and the assembly pulley that is fixed on the pull bar, and described winch is fixed on the deck of refuting body.
Described rear luffing mechanism is comprised of winch, pull bar and the assembly pulley that is fixed on the pull bar, described winch with refute the body deck on the slideway that arranges be connected by anchoring device.
Compared with prior art, advantage of the present invention is apparent, is mainly manifested in:
1, lightweight, shallow draft, center of gravity is adjustable (without counterweight), can sit the beach, is applicable to intertidal zone operation and construction;
2, large, the deck all standing of hoisting crane service range, Self-loading ﹠ self-unloading, installation function;
3, short range is from navigating by water function, position self aligning function; The antiskid function;
4, wind loading rating is strong, safe and reliable, stable, efficient is high;
5, simple in structure, cost is low.

The specific embodiment
A kind of wind power equipment is installed and is used the oscillating type derrick barge, comprise and refute body 1, gantry jib 2, front luffing mechanism 3, rear luffing mechanism 4, lifting mechanism 5, barge propelling unit 6, wherein gantry jib 2 is fixedly mounted on and refutes body 1 medium position, front changing-breadth system 3 connects the upper end of gantry jib column 7 from the barge foredeck, rear changing-breadth system 4 connects the upper end of gantry jib column 7 from the barge aft deck, the front and back luffing mechanism cooperatively interacts, and drive gantry jib 2 and peace lifting mechanism 5 thereon swing realizes that object moves forward and backward; Two cover lifting mechanisms 5 are installed on gantry jib 2, wherein the steel rope 12 on the winch 10 is walked around dead sheave group 11 drive lifting hook pulley groups 13 and is vertically moved the handling object, refute body 1 both sides barge propelling unit 6 is installed, can short range drive the barge navigation and adjust the vessel position.
The integral structure of refuting body 1 satisfies water filling presses the storehouse and can reach the requirement that barge is sat basic skill or training's work, and there is the lateral bearing beam position, intermediate portion, and the twisted axis that satisfies the lower end of gantry jib column 7 supports requirement.
Gantry jib 2 is comprised of left and right sides column truss type 7, top truss frame for connecting crossbeam 8 and pulley crossbeam 9.The winch 10 of lifting mechanism is equipped with respectively in column truss type 7 bottoms in the left and right sides, and pulley crossbeam 9 inside are equipped with two groups of fixed pulley groups 11, and is connected with two groups of lifting hook pulley groups 13 that are suspended on the below respectively by steel rope 12; Pulley crossbeam 9 two ends are connected with fixedly twisted axis 14 on being welded on column truss type 7, when gantry jib swings, pulley crossbeam 9 can swing around this twisted axis, but simultaneously two suspension hook group 13 teamworks or the action that cooperatively interacts, realize respectively load lift and two suspension hooks between lateral offset, installation to bit function.
Luffing mechanism 3 or 4 all is comprised of winch 15, pull bar 16 and the assembly pulley 17 that is fixed on the pull bar 16 on the forward and backward deck, when current luffing mechanism travels forward by the rope traction assembly pulley 17 on the winch 15, pull bar 16 also just drives gantry jib 2 and swings forward, at this moment, the assembly pulley 17 of rear luffing mechanism 4 discharges, to remove the constraint to gantry jib 2, realize that gantry jib 2 swings forward; Vice versa; Deck and barge were outside before, during and after the operating range that has so just guaranteed suspension hook group 13 covered, and finished the demand of goods handling, shipment and sea engineering construction and installation.
The winch 15 of luffing mechanism is packaged type on the aft deck, it with the deck on the slideway 18 that arranges adopt anchoring devices 19 to be connected, when fabricated section larger, front amplitude draw-bar 16, when steel rope 12 might interfere with lifting part, anchoring device 19 can be removed, the heel that winch is moved to gantry jib column 7 is fixed, to abdicate working space.
The sled formula propelling unit 21 of shoal water zone forms barge propelling unit 6 with being applicable to more by the vane type propelling unit 20 that is applicable to the shoal water zone:
Vane type propelling unit 20, it is arranged in the both sides on deck, drive four impellers 24 by the actuating device 22 that top, deck is installed by the drivings device such as cone belt or chain 23, barge can vertically move, the impeller that drives 1 side can make barge turn round, and realizes barge at the short distance navigation of shallow water area and seat in the plane adjustment requirement is installed.
Sled formula propelling unit 21, it is arranged in four bights, deck, push the seabed by the actuating devices such as electrical motor 25 of installing above deck to by crank runner 26 drive sled formula push rods 27, the seabed produces antagonistic force and promotes barge realization short distance navigation or vertically adjust the position, can satisfy horizontal position adjustment needs when actuating device horizontally rotates 90 °, thereby satisfy the installation site accurate adjustment requirement of barge; This propelling unit also comprises a cover sled formula push rod degree of depth setting device 28, by adjusting the degree of depth, can guarantee to prize the formula push rod works under the depth condition of certain limit, behind the barge location positioning, respectively organize this device to the angle that needs by rotation, sled formula push rod can insert the seabed and play the fixedly effect of the slippage stake of barge.
