Abstract
The utility model relates to a fully rotary crane for a ship in the hoisting technology field. The crane consists of a crane ship, a crane main arm, a back bar, a rotating mechanism, a guide rail anda dolly, wherein the crane main arm and the back bar are fixed at the center of the rotating mechanism; both the rotating mechanism and the guide rail are fixed inside or on the outer surface of the deck of the crane ship; the guide rail surrounds outside the rotating mechanism; and the dolly is movably arranged on the guide rail and connected with the back rod through a steel cable or a metal rod. The rotating mechanism only bears pressure load through reasonable design and structural optimization, thereby ensuring simple structure, safety and reliability; the back bar of the crane is connected with the dolly on the guide rail for balancing the crane, so that the majority of balance weight of the traditional crane is eliminated, the weight of the crane is reduced, the structure of the crane is simplified, and the cost is reduced. The draft of the crane ship is reduced through reducing the weight of the crane, so that the working range of the crane ship is enlarged.
Description
Technical field
The utility model relates to a kind of device of hoisting and hanging technical field, specifically is a kind of full circle swinging hoisting crane peculiar to vessel.
Background technology
At present, along with increasing of job tasks such as China's bridge spanning the sea construction, the construction of Oversea wind power generation field, salvage, and the development of ocean engineering industry,,, more, exacting requirements has more been proposed also as crane ship etc. to offshore construction equipment.The design of traditional full circle swinging hoisting crane peculiar to vessel is referred from land full circle swinging crane structure substantially, promptly needs to dispose big weight balancing counterweight, and the stress balance when reaching lifting, luffing prevents that hoisting crane from toppling.The weight of used balance weight the over half of complete machine weight that often account for, therefore, the hoisting crane machine volume is big, weight big, complex structure.Cause bulky, the complex structure of crane ship, and the hull drinking water is bigger, can not be used for the more shallow waters construction of the depth of water, as the construction of shallow water wind power plant.The transportation of this class hoisting crane, installation, dismounting technology are all very complicated.
Though some full circle swinging hoisting crane peculiar to vessel does not need balance block, but adopt cylindrical drum revolving structure supporting hoisting crane, and the balance when guaranteeing hoisting crane work.But because cylindrical drum pivoting support structure is born combined actions such as vertical power, the horizontal force that various load cause, and capsizing moment in hoisting crane work process, not only to consider the intensity and the stability of structure, will guarantee that also structure has enough anti-fatigue performances.Therefore cause complex structure, weight is big, cost is high, and is difficult to the more shallow waters operation of the depth of water.
Find through retrieval: number of patent application 200720087884.4 prior art, Granted publication CN201121102Y, put down in writing a kind of " bracing or strutting arrangement that is used for large-scale full circle swinging hoisting crane ", its supportive body pin gear ring center is a Rotary-table in the ring-type, its outer ring is a ring-type outer ring casing, be connected to a liptinite by i-shaped roof beam between interior Rotary-table and the outer ring casing, the crane rotation body is arranged on pin gear ring top rail by the roller running mechanism, revolution drives the upper and lower and is connected with the pin gear ring with the crane rotation body respectively, anti-idler wheel mechanism is connected the below of crane rotation body, there is the annular walking rails of anti-idler wheel mechanism in the outside of pin gear ring, captives joint with fixed bearing in the bottom of pin gear ring.Yet the prior art structure is too complicated and can't bear lifting task in shallow water area.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of full circle swinging hoisting crane peculiar to vessel is provided, and its reasonable structural arrangement, volume is little, in light weight, load-carrying ability is big, can be at complicated, harsh environment, and shallow waters work.
The utility model is achieved through the following technical solutions, the utility model comprises: crane ship, hoisting crane principal arm, back of the body bar, swing type mechanism, guide rail and dolly, wherein: hoisting crane principal arm and back of the body bar are fixed in the center of swing type mechanism, swing type mechanism and guide rail all are fixed on the inside, deck or the outside face of crane ship, guide rail is surrounded on the outside of swing type mechanism, dolly is movably set on the guide rail, and dolly links to each other by cable wire or Metallic rod with back of the body bar.
Described crane ship is conventional ship type, barge or jack up ship.
The trend of described guide rail is a kind of in circular, ellipse or the polygon, and the cross sectional shape of this guide rail can be a kind of in the C shape of lying, T font or the F font.
The joint face shape of described dolly and the cross sectional shape of guide rail are complementary.
The utility model has the advantages that: swing type mechanism only bears compressive load, and is simple in structure, safe and reliable; Hoisting crane back of the body bar links to each other with dolly on the guide rail, in order to balance crane, has saved most balance weights of conventional hoist, has reduced hoisting crane weight, has simplified crane structure, has reduced cost.The crane ship drinking water has been dwindled in the minimizing of hoisting crane weight, has enlarged the crane ship scope of work.
