Crane elevator for wind power generator repairing

Abstract

The invention discloses a crane elevator for wind power generator repairing. A speed reduction motor, a coiling block, a first transmission box, a second transmission box, a reciprocating rope arranging mechanism and a rope pressing mechanism are included. The coiling block is a folding line coiling block. The reciprocating rope arranging mechanism comprises a reciprocating lead screw and a rope arranging sliding block. The reciprocating lead screw is arranged below the folding line coiling block in parallel and is in transmission connection with the folding line coiling block through the second transmission box. Two guiding rollers are symmetrically arranged and rotationally connected to the rope arranging sliding block. The rope pressing mechanism comprises a supporting rod, a rope pressing roller and a stretching type elastic element, the supporting rod is fixedly connected between the first transmission box and the second transmission box, the rope pressing roller is rotationally connected to the supporting rod and can movably press a steel wire rope wound around the folding line coiling block, and the stretching type elastic element can apply deflecting force towards the folding line coiling block. By means of the crane elevator, multi-layer steel wire ropes can be wound tidily, the requirement of the elevating height is met, and when the steel wire ropes are wound or unwound, the phenomenon of rope disorder is avoided.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a crane hoist for wind power generator maintenance. Background technique [0002] With the depletion of traditional energy, the new energy industry has developed rapidly, among which wind power green energy has developed rapidly. At present, China's cumulative installed wind power capacity has reached one-third of the world's installed capacity, ranking first in the world's cumulative installed capacity of wind power. With the arrival of the wind power maintenance cycle in the later period, the maintenance of wind power equipment has attracted great attention from the entire wind power industry. At present, the maintenance of wind power generation equipment is generally carried out by professional cranes for maintenance of wind power generators. Since wind power generators have a relatively high height (100-160m), this puts forward new requirements for the lifting mechanism of ...

Problems solved by technology

[0003] For winding long steel wire ropes on reels, the following problems are currently faced: 1. Generally, ordinary reels can only wind one layer of steel wire ropes. If you need to wind longer steel wire ropes, you need to expand the diameter of the reel or increase the length of the reel. This method will lead to larger dimensions of the reel, and the cost of raw materials and processing costs will also increase. If a layer of steel wire rope is wound on an ordinary reel, and then the second layer is wound in the opposite direction, the adjacent two layers of wire rope The winding direction is opposite, the two layers of steel wire ropes cross and overlap, and the wear is serious; 2. When the long steel wire rope is wound in multiple layers on the drum, during the winding process, the steel wire rope is easy to be arranged irregularly, and the rope phenomenon appears, which will not only increase the wear of the steel wire rope , reduce the service life of the wire rope, and the lifting of heavy objects is unstable, which may cause accidents such as the wire rope jumping out of the drum in serious cases, posing a safety hazard
