Problems solved by technology

Crawler cranes, as a mobile unit for road construction, are widely used in the hoisting operations of various engineering constructions such as wind power, thermal power, nuclear power, petrochemical, bridges, subways, buildings, etc., but they cannot be directly used in ship hoisting
[0003] On the other hand, the traditional marine jib crane is a crane fixed to the hull, and the slewing mechanism is directly connected to the hull, which can only be used for hoisting

Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] figure 1 with figure 2 Shown is a schematic structural view of a disassembled crane according to an embodiment of the present invention. It can be seen from the figure that the disassembled crane of the present invention at least includes a crane body 1, a jib 3, a luffing mechanism and a lifting mechanism.

[0031] Wherein, the crane body 1 is detachably fixed on the hull 2. As an embodiment, the crane body 1 includes crawler frames (left and right crawler frames) located below it, the crane body 1 is supported by the crawler frames, and the crawler frames pass through Bolts are fixed on the deck of the hull 2. When the aforementioned crawler frame is fixed to the hull 2, the disasse...

Abstract

A split type crane at least includes a crane body (1), an arm (3), a luffing mechanism and a lifting mechanism, wherein the crane body is detachably fixed on a ship body (2). A lower end of the arm (3) is hinged to the ship body (2) or the crane body (1) optionally. When hinged to the ship body (2), the arm is used for water surface lifting; and when hinged to the crane body (1), the arm is used for road surface lifting. The luffing mechanism is used for adjusting the luffing range of the arm, and the lifting mechanism is used for the elevating operation of a lifting hook. The present invention can be used for water surface lifting and road surface lifting, can achieve multiple purposes, and has the advantages of wide applicability, stability, good flexibility and the like.

Description

technical field [0001] The invention mainly relates to the field of engineering machinery, in particular to a split crane. Background technique [0002] In the existing technology, the traditional crawler crane is a mobile road crane. Its main structure includes main parts such as loading, unloading, slewing platform, luffing mast, superlifting mast and jib. The jib is directly installed on the main platform. . Crawler cranes, as a mobile unit for road construction, are widely used in hoisting operations in wind power, thermal power, nuclear power, petrochemical, bridge, subway, construction and other engineering constructions, but they cannot be directly used in ship hoisting. [0003] On the other hand, the traditional marine jib crane is a crane fixed to the hull, and the slewing mechanism is directly connected to the hull, so it can only be used for hoisting of ships. Promptly the marine jib crane of prior art is a kind of special-purpose crane limited to water surface...
