下面结合附图来详细描述本发明的优选实施例。 应当理解, 所讨 论的优选实施例仅示范性地说明实施和使用本发明的特定方式, 而非 限制本发明的范围。
本发明的核心思想是, 通过机构设计, 检测机构首先通过机械 /物 理的方式存储一定的势能, 过行程拨杆 /顶杆运动到某一位置时, 能触 发检测机构势能释放, 转换为标靶运动, 改变标靶位置, 从而实现检 测。
参见图 1 ,示出了根据本发明的飞机转弯过行程检测装置的结构示 意图。本发明的飞机转弯过行程检测装置 100包括过行程顶杆 20和检 测组件, 过行程顶杆 20安装在飞机前起落架转弯动作套筒 10的旋转 部分上, 并随着旋转部分的旋转而旋转, 过行程顶杆 20用于指示转弯 的角度状态, 并触发检测机构动作。
检测组件安装在飞机前起落架转弯动作套筒的静止部分上。 具体 地, 检测组件包括接近传感器 30、 标靶 40、 储能弹簧 50、 套筒 60、 连杆 70和联动卡勾 80, 其中接近传感器 30、 套筒 60和联动卡勾 80 固定在飞机前起落架转弯动作套筒的静止部分上。接近传感器 30用于 检测标靶 40的位置, 例如, 检测标靶 40是否接近接近传感器 30; 套 筒 60位于标靶 40的下方, 储能弹簧 50位于套筒 60内并处于压缩状 态; 连杆 70的一端穿过套筒 60的底部和储能弹簧 50, 并与标靶 40 连接, 另一端具有锁扣部 71, 例如, T形部, 连杆 70可在套筒 60内 自由滑动,套筒 60约束连杆 70以及标靶 40的滑动位置,联动卡勾 80 与连杆 70的锁扣部相锁扣。
联动卡勾 80可以是单边动作式或双边啮合联动式。 优选地, 联动 卡勾 80包括左卡勾 81、 右卡勾 82和转轴 84, 左卡勾 81和右卡勾 82 围绕共同或各自的转轴 84相对地转动, 以打开和闭合联动卡勾 80。联 动卡勾 80还包括卡勾弹簧 83, 卡勾弹簧 83连接左卡勾 81和右卡勾 82。 联动卡勾弹簧 83用于约束联动卡勾 80, 使联动卡勾 80有向中心 的卡紧力, 从而卡紧连杆 70, 约束标靶 40 的初始位置。 当联动卡勾 80打开并释放连杆 70后, 再次使联动卡勾 80自动闭合, 限制连杆 70 可能的由于竖立方向振动或其他原因, 误动作回到初始状态。
储能弹簧 50的初始状态为压缩状态, 储存势能, 势能被触发释放 后,可推动连杆 70和标靶 40运动到特定位置,与接近传感器 30接近。 联动卡勾 80可绕转轴 84转动, 用于卡住连杆 70, 初始状态时, 卡住 连杆 70, 约束储能弹簧 50的势能。
在本发明的上述实施例中, 接近传感器选用飞机其他位置相同的 接近传感器, 标靶为不锈钢片, 除储能弹簧外, 其他结构材料为 7075 铝合金, 以减轻重量, 提高动作敏捷性。
本发明的飞机转弯过行程检测装置的检测原理为: 基于接近传感 器和标靶、 以及标靶驱动机构的过行程指示装置; 标靶驱动由储能弹 簧、 联动卡勾等控制, 当发生过行程时, 顶杆顶开联动卡勾, 标靶在 储能弹簧驱动下接近或离开传感器, 实现过行程位置检测; 同时, 发 生过行程后, 标靶位置已通过机械方式锁定, 必须通过机务手动复原。
如图 1所示, 未发生过行程时, 即初始状态时, 接近传感器 30与 标靶 40脱开, 无过行程信号产生。
如图 2所示, 发生过行程时, 过行程顶杆 20顶开联动卡勾 80, 连 杆 70在储能弹簧 50作用下带动标靶 40向接近传感器 30移动, 接近 传感器 30捕捉到该信号,并将信号经由控制单元处理为数字或离散量 信号, 发送给飞机控制系统的相应处理单元, 进行切断转弯能源、 并 在航电系统指示或记录转弯过行程已发生。
如图 3所示,发生过行程后,标靶 40的位置已通过机械方式锁定, 即使飞机电源重启, 该位置仍保留不变, 当机务检查或飞机重新上电 时, 提示机务已发生过行程, 需采取进一步的维修或检查。 检查转弯 系统结构未损坏, 功能正常后, 可通过手动方式, 将标靶和储能弹簧 压缩回套筒, 拔开联动卡勾将连杆卡住, 等待下一次过行程检测。
在使用中, 需要注意以下几个方面:
( 1 )初始位置时, 连杆的 T形部沿离套筒底部的距离应与标靶与 接近传感器的间距相当;
( 2 )套筒的内径应能够容纳储能弹簧和连杆滑动, 同时不发生明 显的横向摆动;
( 3 )储能弹簧的自由长度, 应稍大于接近传感器和套筒底部的间 距, 这保证在过行程后, 标靶能与接近传感器较可靠地接触; 该储能 弹簧要求有较大的弹性系数, 保证标靶动作尽可能迅速;
( 4 )联动卡勾可根据实际情况, 设计成单边动作式, 或双边啮合 联动式, 后者左右两片卡勾通过接触的齿轮状结构啮合联动, 保证卡 住连杆的左右卡勾同步动作, 同时, 该形式左、 右两个方向都可触发 检测, 可用于过行程左右方向限制角度接近 180度的情形;
( 5 )联动卡勾弹簧需具备一定的预紧力, 弹性系数应较大, 避免 由于振动、 风载等原因误动作打开联动卡勾。 本发明的检测装置动作可靠, 易于检测, 发生过行程后, 标靶位 置已通过机械方式固定, 只有通过机务手动才能复位, 不需更换新机 构, 维护简便, 在多种机型转弯过行程检测中均可应用。
本发明中所述具体实施案例仅为本发明的较佳实施案例而已, 并 非用来限定本发明的实施范围。 即凡依本发明申请专利范围的内容所 作的等效变化与修饰, 都属于本发明的保护范围。
