Problems solved by technology

In the process of disassembly and installation, it is also necessary to disassemble the hook and thread the wire rope. The entire disassembly process takes a long time, which undoubtedly consumes time and manpower. At the same time, the disassembly structure requires auxiliary crane operation and auxiliary vehicle transportation, which increases the transition cost.

Embodiment Construction

[0047] Combine below Figure 1 to Figure 7 The technical solution provided by the present invention is described in more detail.

[0048] Explanation of nouns or terms involved in this article.

[0049] Wind power arm: a truss arm structure, the main body is made of pipes to form a rectangular section. The performance and arm length are mainly developed for wind power operations, so it is called wind power arm.

[0050] Super Lifting Device: Installed on the box-shaped main boom, it cooperates with the wire rope to increase the rigidity of the boom.

[0051] see figure 1 , the embodiment of the present invention provides a wind power arm turning method, including the following steps:

[0052] Step S10, rotatably connecting the main arm 1 of the crane and the wind power arm 2.

[0053] Generally speaking, the main arm 1 of the crane is connected with the wind power arm 2 by multiple pins. When the wind power arm 2 needs to be turned over, some of the pins need to be removed...

Abstract

The invention discloses a method for overturning a wind power boom and a crane, relating to the field of engineering machinery, and is used for realizing transition transportation with a wind power boom crane without using other auxiliary vehicles. The wind power arm turning method includes the following steps: connecting the main arm of the crane to the wind power arm rotatably; using the traction device arranged on the crane to rotate the wind power arm to the first set position; The wind power arm is in contact; continue to pull the wind power arm to the second set position; release the traction device, and the wind power arm will automatically turn over under the action of its own gravity and buffer components until the wind power arm turns over in place. The above-mentioned technical scheme enables the crane to turn over without the aid of other auxiliary cranes, and provides convenient conditions for the transfer of the crane.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a wind power boom turning method and a crane. Background technique [0002] With the intensified competition in the crane hoisting market, the profits of super-large-tonnage cranes in the general hoisting market have plummeted. At present, the main profit-making areas of domestic super-large-tonnage crane hoisting work are concentrated in the wind power installation and maintenance market. [0003] The demand for cranes in the wind power installation and maintenance market is no longer the overall performance advantage in a wide range and large-scale field, but focuses on the requirements for lifting weight when the lifting height is large. [0004] The inventors have found that at least the following problems exist in the prior art: currently on the market, the main hoisting work performed by super-large tonnage cranes is fan installation. After the installation of a fan is ...
