AI Technical Summary

Problems solved by technology

The hoisting of the fan is a complex system engineering. It not only needs to hoist the whole fan, but also needs to hoist the impeller and install the impeller in the casing. At present, for larger fans, the impeller is relatively heavy, and the hoisting and installation of the impeller is relatively more difficult

Embodiment 1

[0064] figure 1 A step flow chart of a method for hoisting a wind turbine according to an exemplary embodiment of the present invention is shown.

[0065] Such as figure 1 As shown, the hoisting method of a fan of this embodiment includes:

[0066] Establish a three-dimensional model and environmental model of the fan to be installed, and obtain the hoisting track of the fan based on the three-dimensional model and environmental model;

[0067] Based on the three-dimensional model, hoisting holes 3 are set on the casing of the fan;

[0068] Based on the three-dimensional model, a hoisting plate 5 is set above the hoisting hole 3;

[0069] Based on the environment model, mark the positioning points on the lifting plate 5;

[0070] Based on the positioning point, a plurality of hoisting ropes are symmetrically wound on the hoisting plate 5, and when hoisting, the center of gravity of the plurality of hoisting ropes is on the center line of the casing, and hoisting is carried out according ...

Abstract

The invention discloses a fan hoisting method. The fan hoisting method comprises the steps that a hoisting hole is formed in the casing, a hoisting plate is arranged above the hoisting hole, a plurality of hoisting ropes are symmetrically wound on the hoisting plate, and during hoisting, the gravity centers of the plurality of hoisting ropes are arranged on the center line of the casing. The method has the advantages that when an impeller needs to be dismounted and mounted, the hoisting plate is taken down, operation is directly carried out through the hoisting hole, the mounting efficiency ofthe impeller is improved, after the impeller is mounted, the hoisting plate is fixed, the whole fan is hoisted to a required place through the hoisting plate, the overall hoisting efficiency is improved, the hoisting hole can be covered due to the arrangement of the hoisting plate, cleanliness in the casing is improved, and the safety of a fan is improved.

Description

Technical field [0001] The invention relates to the technical field of fan hoisting, and more specifically, to a method for hoisting a fan. Background technique [0002] Fan is the habitual abbreviation for gas compression and gas transportation machinery in our country. Generally speaking, fans include: ventilator, blower, and wind generator. Gas compression and gas transport machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy, and transports the gas out. [0003] The fan is composed of impeller, casing, air inlet, bracket, motor, pulley, coupling, muffler, transmission parts and other components. The hoisting of a fan is a complicated system project. It is not only necessary to hoist the entire fan, but also to hoist the impeller, and install the impeller in the casing. At present, for larger fans, the impeller is relatively heavy, and the impeller is relatively heavy. Harder. [0004] Therefore, it is necessary to develop ...
