Abstract
The utility model relates to a special tooling of a wind generator, in particular to a lifting tool of a main shaft bearing end cover of the wind generator. The technical scheme is as follows: the lifting tool comprises three hanging rods (3) and three lifting pins (1), wherein the three hanging rods are in head-to-tail connection for constituting a triangle, the three lifting pins are arranged on three angles of the triangle, steps are arranged at the bottom of each lifting pin, and lifting holes (4) are arranged at the upper parts of the lifting pins. Due to the adoption of the lifting tool, lifting hooks are directly hooked on the lifting holes of the lifting pins for lifting, and the lifting hooks are detached after completion to being released from the movable lifting pins, then the triangle can be decomposed and the lifting tool can be moved away without a whole main shaft being crossed over. The lifting tool is characterized by reasonable structure, strong universality, safe and convenient operation and the like.
Description
Affiliated technical field:
The utility model relates to a kind of aerogenerator special tooling, particularly mainshaft bearing of wind-driven generator end cap hoisting appliance.
Background technology:
During the wind driven generator principal shaft assembling, roller bearing end cap need be sling from the bottom up, itself and bearing seat are assembled.The oad of roller bearing end cap is less than bearing seat, and common suspender can not directly lift by crane.Since there is not special-purpose hoisting appliance, inconvenient operation, dangerous.
The utility model content:
The utility model purpose provides a kind of mainshaft bearing of wind-driven generator end cap hoisting appliance, and commonality is good, and the safety of operation facility solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
Mainshaft bearing of wind-driven generator end cap hoisting appliance comprises three suspension rods, three lifting pins, three suspension rods formation triangle that joins end to end, and three lifting pins are arranged on leg-of-mutton three angles, and step is arranged at lifting pin bottom, and lifting pin top is provided with hole for hoist.
The hole for hoist that said lifting pin top is provided with can be the lifting hole(eyelet) of opening on lifting pin, also can on the lifting pin suspension ring be set, and perhaps the lifting pin is gone up fluted, transverse axis and is combined into hole for hoist.
The utility model also is provided with shaft end ring, is enclosed within on the lifting pin, and fixing lifting pin can not be deviate from it.
Adopt the utility model, drop hanger directly colludes on the hole for hoist of lifting pin and lifts, and unloads suspension hook after finishing, and deviates from movable lifting pin, triangle can be decomposed and remove this suspender, does not need to pass through whole main shaft.
The utlity model has characteristics such as rational in infrastructure, highly versatile, easy-to-operate.
Description of drawings:
Accompanying drawing 2 is the utility model cross-sectional schematic.
Among the figure: lifting pin 1, the disconnected back-up ring 2 of axle, suspension rod 3, hole for hoist 4.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, mainshaft bearing of wind-driven generator end cap hoisting appliance comprises three suspension rods 3,1, three suspension rod of three the lifting pins formation triangle that joins end to end, and three lifting pins are arranged on leg-of-mutton three angles, step is arranged at lifting pin bottom, and lifting pin top is provided with hole for hoist 4.The hole for hoist that said lifting pin top is provided with is that the lifting pin is gone up the hole for hoist fluted, that transverse axis is combined into.The utility model also is provided with shaft end ring 2, is enclosed within on the lifting pin, and fixing lifting pin can not be deviate from it.
Use: earlier the main shaft bearing end cap is placed on the wooden unit that has filled up certain altitude, suspension rod outsourcing one deck flannelette prevents the part of damaging.Below with the sealing triangle of three suspension rod makeup rings, penetrate a remaining lifting pin at roller bearing end cap from bottom to top, hook this movable lifting pin with closed suspension hook and do not make it deviate from suspension rod around main shaft.Having colluded two other suspension hook lifts.After finishing this suspender is fallen, unloaded suspension hook, deviate from movable lifting pin.
