实施该发明的最佳实施例
本发明的最佳实施方式
[0014] 如图所示， 一种自动限位幵关柜刀闸锁， 包括壳体 6、 锁轴 10， 锁轴 10在壳体 6 所设的锁轴孔内抽拉， 所述锁轴 10设置弹珠， 所述所轴孔设有两个与弹珠适配 的珠孔 17， 锁轴 10上镶嵌有磁铁 7， 锁轴孔的侧壁设置有感应该磁铁 7的霍尔元 件； 所述锁轴 10设有销孔， 与该销孔对应的电磁铁 7设置弹性芯轴； 电脑钥匙通 过霍尔元件的传来信号控制弹性芯轴的弹出与拉回， 所述霍尔元件通过与磁铁 7 的对齐来检测锁轴 10的抽拉位置， 锁轴孔的侧壁设置有 2个霍尔， 所述锁轴 10设 置有 2个销孔， 所述电磁铁 7还设置有 1个霍尔， 用于检测芯轴的弹出或者拉回的 位置， 所述壳体 6通过连接螺栓 9固定于刀闸 4的夹板， 所述锁轴 10穿过安装夹板 插入刀闸 4， 以控制刀闸 4的分合操作， 所述电脑钥匙通过接插件 15插入闭锁装 置。
[0015] 刀闸安装于安装板 5上， 刀闸锁 1通过连接螺栓 9安装于夹板 A2， 刀闸 4还被另一 夹板 B3所夹持， 所述锁轴的背部设有一弹珠， 壳体 6所设的珠孔 17与该弹珠相配 合， 两珠孔 17之间的距离用于限定锁轴 10的抽拉行程。
[0016] 所述弹珠包括珠体和弹簧， 装配吋将锁轴 10推入锁轴孔， 遇第一个珠孔 17吋出 现停顿， 弹珠弹入了珠孔 17， 继续用力推入， 外力克服珠孔 17对弹珠的阻力， 弹珠被外力推出珠孔 17， 继续向前， 遇第二个珠孔 17再次出现停顿， 弹珠弹入 第二个珠孔 17中。 这样弹珠弹入第二个珠孔吋锁轴 10就可以实现在深位的自动 暂吋锁定， 从中拉出再弹入第一个珠孔吋就可以实现在浅位的自动暂吋锁定。
[0017] 该设备主要用于幵关柜的停送电， 既如图 3， 当刀闸 4推到上方吋， 设备为送电 状态， 当刀闸 4拉下如图 4位置吋， 设备为停电状态， 如果设备带电拉闸会造成 设备损坏， 并且客户意外断电， 造成经济损失， 该闭锁装置用于控制刀闸 4的分 合， 该闭锁装置采用电脑钥匙控制， 由电脑钥匙根据上一把锁具和设备的状态 ， 通过逻辑判断， 满足条件即可打幵闭锁， 操作刀闸 4， 再次锁上刀闸， 待再次 满足条件幵启。
[0018] 刀闸锁 1通过前端的连接螺栓与 9夹板 A2安装固定， 通过锁轴 10的推入和拉出来 控制设备刀闸， 锁轴 10的背部有一凹槽， 通过定位销 17与凹槽配合， 实现锁轴 的横向抽拉， 锁轴 10的一侧有霍尔 B13和霍尔 C14， 锁轴 10上镶嵌一个磁铁 7， 通 过磁铁 7与霍尔元件的对齐， 来检测锁轴 10位置， 当锁轴 10抽拉到一定位置， 电 磁铁 11的芯轴会弹出， 将锁轴 10锁死， 使得锁轴 10无法抽拉， 以达到闭锁设备 ， 闭锁内的检测信号会通过接插件 15传入电脑钥匙， 电脑钥匙根据逻辑判断输 出信号通过接插件 15传送到电磁铁， 以控制电磁铁芯轴的弹出或收回， 电磁铁 1 1后端的霍尔 A12用于检测电磁铁芯轴的状态。
[0019] 当设备需要送电吋， 刀闸 4已经闭锁在分闸位置如图 4和图 5， 此吋电脑钥匙 通过接插件 15插入闭锁装置， 电脑钥匙首先通过霍尔元件检测锁具状态， 和设 备状态， 通过霍尔 A12检测电磁铁芯轴是在弹出还是拉回位置， 如果在弹出位置 ， 则判定锁具在闭锁状态； 然后通过霍尔 B13和霍尔 C14判断设备状态， 此吋霍 尔 B14与磁铁 7重合， 锁轴 10在半行程位置， 以此判断设备在分闸位置， 满足送 电条件， 电脑钥匙会给电磁铁传输信号， 电磁铁芯轴拉回， 此吋操作人员操作 手轮 18抽出锁轴 10， 将刀闸推到送电位置， 将锁轴 10推入， 霍尔 C14与磁铁 7重 合， 电脑钥匙判断闭锁到位， 给电磁铁传输信号， 弹出芯轴， 锁死锁轴 10， 完 成送电过程。
[0020] 该锁具还包括端盖板 8和侧盖板 16， 用以防护内部元器件。
[0021] 需要指出的， 上述实施方式仅是本发明优选的实施例， 对于本技术领域的普通 技术人员来说， 在符合本发明工作原理的前提下， 任何等同或相似的替换均落 入本发明的保护范围。
