Abstract

本发明公开了一种提高风力发电机组叶片吊装对接效率的简易装置，其包括导向销1、导向套2、螺杆3、导轨4及固定螺栓。导向套2、导轨4、螺杆3及固定螺栓安装在变桨轴承内圈法兰A上，导向销1安装在叶片C上。叶片C吊装对接时，首先导向套2引导导向销1进入变桨轴承内圈法兰A螺栓孔，之后导向销1引导叶片C螺栓进入变桨轴承内圈法兰A螺栓孔，最后松掉导向套2的固定螺栓，旋转螺杆3，把导向套2从叶片C和变桨轴承内圈法兰A之间移出。本发明提高了叶片吊装对接效率。

Description

一种提高风力发电机组叶片吊装对接效率的简易装置
技术领域
本发明涉及风力发电机组叶片吊装装配领域，特别是海上风力发电机组单叶片吊装装配领域。
背景技术
目前，风力发电机叶片吊装装配时，一部分厂家采用导向销导向，导向销与变桨轴承螺栓孔间隙只有13mm左右，叶片受到风载的作用，叶片会晃动，直接采用导向销与变桨轴承孔对接效率低；另外一部分厂家直接采用叶片螺栓直接对接变桨轴承螺栓孔，叶片螺栓与变桨轴承孔间隙只有1.5mm左右，对接效率更低。海上风力发电机组功率越来越大，叶片越来越长，由于海上安装平台的空间限制，普遍开始采用单叶片吊装，叶片在高空中受到风载的作用，叶片会晃动，叶片与变桨轴承直接对接效率低。
发明内容
有鉴于此，本发明提供了一种提高风力发电机组叶片吊装对接效率的简易装置。
本发明的技术方案为：
一种提高风力发电机组叶片吊装对接效率的简易装置，包括导向销、导向套、螺杆、导轨及固定螺栓，导向销安装在叶片上，导向套、螺杆、导轨及固定螺栓安装在变桨轴承内圈法兰上，通过导向套引导导向销进入变桨轴承内圈螺栓孔，进而引导叶片螺栓进入变桨轴承内圈螺栓孔。
进一步地，导向套孔与变桨轴承内圈螺栓孔对齐。
进一步地，导向套为锥形孔，由于固定在变桨轴承内圈法兰上，方便引导导向销进入导向套及变桨轴承内圈法兰螺栓孔。
进一步地，导向套的非固定端为开口，当导向销进入变桨轴承内圈法兰螺栓孔后，松掉导向套的固定螺栓，在先不取出导向销的情况下，可以取出导向套。
进一步地，导向套有螺纹孔，当叶片压紧变桨轴承内圈法兰时，可以通过旋转螺杆把导向套取出。
进一步地，导向套的非固定端上下面有一定斜度，减小取出导向套的阻力。叶片吊装对接时，首先导向销插入导向套，导向套引导导向销进入变桨轴承内圈法兰螺栓孔，之后导向销引导叶片螺栓进入变桨轴承内圈螺栓孔，最后松掉导向套的固定螺栓，旋转螺杆，把导向套从叶片和轴承内圈法兰之间移出。
本发明的有益效果在于：
本发明装置简单，明显提高了叶片吊装对接效率。
附图说明
图1、2均为本发明装置安装在风机上的示意图，A为变桨轴承内圈法兰，B为本发明的装置，C为叶片。
图3为本发明的结构示意图，1为导向销，2为导向套，3为螺杆，4为导轨。
具体实施方式
为了使本技术领域人员更好地理解本发明方案，下面结合附图和具体实施方式，对本发明作进一步的详细说明。
如图1至图3所示，4组导向套2、螺杆3、导轨4及螺栓均布安装在变桨轴承内圈法兰A上，导向套2与变桨轴承内圈法兰A螺栓孔对齐，4个导向销1均布安装在叶片C上。导向套2为锥形孔，由于固定在变桨轴承内圈法兰A上，方便引导导向销1进入导向套2及变桨轴承内圈法兰A螺栓孔；导向套2的非固定端为开口，当导向销1进入变桨轴承内圈法兰A螺栓孔后，松掉导向套2的固定螺栓，在先不取出导向销1的情况下，可以取出导向套2；导向套2有螺纹孔，当叶片C压紧变桨轴承内圈法兰A时，可以通过旋转螺杆3把导向套2取出；导向套2的非固定端上下面有一定斜度，减小取出导向套的阻力。
吊装叶片C对接时，首先导向销1插入导向套2，通过导向套2引导导向销1进入变桨轴承内圈法兰A螺栓孔，之后导向销1引导叶片C螺栓进入变桨轴承内圈法兰螺栓孔，最后松掉导向套2的固定螺栓，旋转螺杆3，把导向套2从叶片C和轴承内圈法兰A之间移出。
