Description

一种磁力吊
技术领域
本发明涉及起重设备配件领域,特别是涉及一种磁力吊。
背景技术
在我国机械加工、模具制造、冶金等行业,一些笨重钢板或铁板,有精度要求或者表面粗糙度要求的钢铁加工成品或半成品等的起吊,大多采用钢丝捆绑再起吊的方法,或者用电磁铁起吊。但电磁铁体积大、成本高,且故障多、维护困难,电磁铁在工作中,要消耗大量电能,一旦停电,易发生事故。
发明内容
本发明主要解决的技术问题是提供一种磁力吊,采用高性能永磁材料,通过手柄翻转改变磁力线使磁力吊处于工作或者关闭状态,无需外界供电,安全节能。
为解决上述技术问题,本发明采用的一个技术方案是:提供一种磁力吊,包括:本体、位于所述本体上端的把手、位于所述本体一侧的控制手柄,所述控制手柄通过转轴与所述本体内的永磁体连接,所述永磁体是由高性能稀土永磁材料制成,所述高性能稀土永磁材料为钕铁硼永磁材料,其主要成分及质量百分比为:钕30-35%、硼20-25%、铁25-30%、铜8-10%、铝5-8%、钴2-6%。
在本发明一个较佳实施例中,所述钕铁硼永磁材料的主要成分及质量百分比为:钕32%、硼22%、铁27%、铜9%、铝6%、钴4%。
在本发明一个较佳实施例中,所述控制手柄的上端设有控制按钮。
本发明的有益效果是:永磁体采用高性能钕铁硼永磁材料制成的,具有很高的剩磁感应强度、很高的磁能积,且具有很高的矫顽力,该磁力吊通过手柄翻转改变磁力线使其处于工作或者关闭状态,无需外界供电,安全节能。
附图说明
图1是本发明一种磁力吊一较佳实施例的结构示意图;
附图中各部件的标记如下:1、本体,2、把手,3、控制手柄,4、转轴,5、控制按钮。
具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述,以使本发明的优点和特征能更易于被本领域技术人员理解,从而对本发明的保护范围做出更为清楚明确的界定。
请参阅图1,本发明实施例包括:
一种磁力吊,包括:本体1、安装在所述本体1上端的把手2、和连接在所述本体1一侧的控制手柄3;所述把手2是由耐磨ABS塑料制成的,便于移动磁力吊;所述控制手柄3通过转轴4与所述本体1内的永磁体连接,所述永磁体是由高性能稀土永磁材料制成,所述高性能稀土永磁材料为钕铁硼永磁材料,其主要成分及质量百分比为:钕30-35%、硼20-25%、铁25-30%、铜8-10%、铝5-8%、钴2-6%。
优选地,所述钕铁硼永磁材料的主要成分及质量百分比为:钕32%、硼22%、铁27%、铜9%、铝6%、钴4%。
所述控制手柄3的上端设有控制按钮5,通过所述控制按钮5以控制所述控制手柄3的翻转,以改变磁力线,以控制磁力吊处于工作或关闭状态。
本发明揭示了一种磁力吊,采用高性能钕铁硼永磁材料制成的永磁体,同时永磁铁连接有可以改变磁力线方向的控制手柄,该磁力吊具有很高的剩磁感应强度、很高的磁能积,尤其是无需外界供电,安全节能。
以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
