Embodiment Construction

[0021] According to the accompanying drawings of the description, the variable bow self-propelled floating crane of the present invention is further described in detail as follows:

[0022] as attached figure 1 And attached figure 2 As shown, the structure of the variable bow self-propelled floating crane of the present invention includes a bow 1, a hull 2, a turning line 4, a middle line 5, a turning shaft 6, a buckle ear 7, a buckle hole 8 and a buckle. axis 10. The bow 1 and the hull 2 ​​are divided into free front and rear independent floating bodies by the turning line 4, and the bow 1 is divided into left and right free independent floating bodies by the center line 5, and the left and right independent floating bodies of the bow 1 pass through the turning axis 6 Rotate and abduct in opposite directions, turn back 180 degrees, make the two sides of the bow 1 and the two sides of the hull 2 ​​close together, and connect and fix through the turning shaft 6, fastening ea...

Abstract

The invention relates to a changeable-prow self-propelled floating crane which structurally comprises a prow, a ship body, a fold line, a trunk line, a rotating shaft, a buckle fixing lug, buckle fixing holes and a buckle fixing shaft. The floating crane is characterized in that a floating crane ship in a normal state adopts a streamline design which is same as that of a common ship; the prow is separated from the ship body through the fold line and is separated by the trunk line to form three free independent floating bodies; two independent floating bodies of the prow are respectively connected with the ship body through the rotating shaft to form a whole body and can rotate around the rotating shaft serving as a circle center to expand outwards and the fold to form that the three floating bodies are transversely flush side by side; and the three floating bodies are locked by the buckle fixing lug, the buckle fixing holes and the buckle fixing shaft to form a complete and uniform novel floating crane floating body. Compared with the prior art, the changeable-prow self-navigation floating crane has the outstanding advantages of small self-propelled resistance, high speed, high efficiency, high ratio of ship body displacement to lifting capacity, stability and safety in working, high cargo stacking capacity of a deck and the like, thus having high popularization and use values.

Description

1. Technical field: [0001] The invention relates to aerial crane equipment, in particular to a variable bow self-propelled floating crane. 2. Background technology [0002] With the wider discovery, development and utilization of marine resources, there is a huge demand for the number and scale of floating cranes serving this purpose. Floating cranes in the prior art, whether they are self-propelled or barge-towed, fixed or slewing, have many constraints and defects, which limit the production and application of floating cranes, mainly in the following areas: [0003] 1. In order to maintain the stable lifting capacity of the floating crane operation, the gravity center of the boom must be close to the buoyancy center of the floating crane. If it is too large, it will seriously affect the lifting capacity and make the operation extremely inconvenient. [0004] 2. In order to facilitate the operation and improve the lifting capacity, the floating crane ships mostly adopt th...
