+2. 字幕：应急切换。
+
+### 解说词原文
+
+GQZ009型重型支援桥作为应急保障力量的重要组成部分，在抢险救灾中起到了关键作用。在架设与撤收中，液压系统作为装备的动力系统，特别是液压系统的心脏——液压泵，这一关键部件的可靠性直接关系到能否完成桥梁架设撤收作业，面对复杂的战场环境，一旦液压系统出现故障，就会导致桥梁架设撤收作业被迫中断，甚至引发危险状态。
+
+那在战时，如果液压泵损坏，该怎样快速完成架桥任务呢？
+
+通过对液压系统分析可知，重型支援桥液压系统采取了“双泵独立供油”的设计理念，因此，如果其中一个液压泵出现损伤，可以采取应急切换的方法，快速完成装备抢修。
+
+> 整理说明：型号暂录为“GQZ009”，建议以清晰原件核对，不由产品型号常识替换。图中只有上述画面要求，没有附上原理图及三类场景素材。

+
+### 解说词原文
+
+那什么是应急切换呢？
+
+在装备战场抢救抢修中，切换是一种应急修理方式，其是指通过回路转换或改接，脱开损伤部分，接通备用部分，或者将原来担负非基本功能的完好部分改换到基本功能回路中。
+
+针对重型支援桥，应急切换是指在单个液压泵或取力器出现故障时，通过切换到另一个液压泵继续完成架设或撤收作业的方法。

+
+### 解说词原文
+
+重型支援桥是如何实现应急切换的？
+
+我们从原理上来寻找答案，根据液压系统原理，重型支援桥设置有2个供油回路，一个是前泵供油回路，由前泵提供动力，主要负责为托架液压系统和架设架液压系统提供动力，主要由液压油箱、前泵、前泵出油滤油器、托架多路换向阀连接块内的三通流量调节阀、回油滤油器等构成完成的液压回路；另一个是后泵供油回路，由后泵提供动力，主要负责为支腿液压系统和吊机液压系统提供动力，主要由液压油箱、后泵、后泵出油滤油器、支腿多路换向阀连接块内的三通流量调节阀、回油滤油器等构成完成的液压回路。
+
+> 整理说明：“构成完成的液压回路”按图片文字保留，疑为“构成完整的液压回路”。
+
+## 讲解4：打开球阀后的回油问题（005-L04）
+
+来源：[3.jpg](../3.jpg)至[4.jpg](../4.jpg)开头，连续原理段。
+
+### 画面提示原文
+
+（1）打开球阀。
+
+### 解说词原文
+
+此时，我们应该注意到在两个出油滤油器的出口处设置一球阀，在正常情况下，该球阀处于关闭状态。
+
+那如果将该球阀打开，会出现什么样的情况呢？
+
+此处以托架马达向前为例说明，当操作手操作托架马达向前时，来自负载侧的压力会将托架多路换向阀连接块内的三通流量调节阀关闭，此时来自前泵的液压油无法通过托架多路换向阀连接块内的三通流量调节阀返回液压油箱，应通过托架多路换向阀内部通道进入托架马达换向联，而后进入液压马达，推动液压马达旋转。
+
+但此时液压马达侧负载压力较大，液压油便不会进入液压马达，是而是经打开的球阀，进入支腿多路换向阀连接块内，通过支腿多路换向阀内的三通流量调节阀返回液压油箱。
+
+操作托架液压系统和架设架液压系统的任一执行机构时，均会出现上述现象。同理可分析，操作支腿液压系统和吊机液压系统的任一执行机构时，也会出现上述现象。
+
+那在前泵损坏的情况下，可否利用液压系统这一设计理念，完成重型支援桥的架设和撤收作业呢？
+
+通过上述分析，操作重型支援桥任一执行机构时，负载侧压力总会关闭相应的多路换向阀连接块内的三通流量调节阀，使得来自液压泵的液压油从另一多路换向阀连接块内的三通流量调节阀返回液压油箱，因此，如果提前关闭两个多路换向阀连接块内的三通流量调节阀，则无论来自哪个液压泵的液压油均不会返回液压油箱，那通过哪个元件关闭三通流量调节阀呢？
+
+> 整理说明：最后一段在3.jpg末行“负载侧压力总会”后跨页，4.jpg从“关闭相应的……”继续；已连为完整段落。“是而是”按可见原文保留，疑为“而是”。
+
+## 讲解5：自救阀与切换原理（005-L05）
+
+来源：[4.jpg](../4.jpg)上半部。
+
+### 画面提示原文
+
+（2）打开自救阀。
+
+### 解说词原文
+
+此时我们应注意到，托架多路换向阀和支腿多路换向阀的M口各串联一自救阀，如果将该自救阀打开，则在接通取力器时，来自液压泵的液压油便将三通流量调节阀关闭。
+
+因此，在实施切换时，还需打开自救阀。
+
+## 进入操作阶段的引导原文
+
+来源：[4.jpg](../4.jpg)下半部。
+
+### 画面与字幕原文
+
+4. 字幕：
+   - 一、应急切换是什么
+   - 二、应急切换怎么实现
+   - 三、应急切换该怎么做
+
+画面：重型支援桥实装，具体操作。
+
+### 引导解说原文
+
+以上就是应急切换的原理，那在前泵损坏的情况下，该如何操作呢？操作方法具体如下：
+
+## 具体操作原文
+
+来源：[4.jpg](../4.jpg)，被手写圈线标出的操作段。以下分项编号为整理时添加，原稿使用“首先／而后／最后”衔接。
+
+1. 首先，根据故障现象确定是哪一个液压泵发生故障；
+2. 而后，断开架桥车取力器；
+3. 而后，将架桥车备胎斜上方连接两个红色滤油器的球阀打开；注意：手柄由垂直于管路方向旋转至平行于管路方向。
+4. 而后，重新接通取力器；
+5. 而后，打开辅助控制盒内的“互救”开关。
+
+最后，利用一个液压泵继续完成作业，作业时按照正常的装备操作要求进行操作即可。
+
+## 待核对与素材记录
+
+- 原理段“打开自救阀”与操作段“互救开关”的对应关系没有在图片中解释，不能据此认定为同一操作或自行增加一步。
+- 最后一段继续作业为原文内容，不能因当前系统只有五步就省略；具体后续作业动作未在本图展开。
+- 两个液压泵画面、液压原理图、环境与救灾画面均为原稿要求，需另行关联素材。

+
+> 原文疑点：本组第③项同样同时出现装配与拆卸指令，需要核定。
+
+## 待核对与素材记录
+
+- 背景为空，不能把005／006／007的前泵撞击事故直接作为本项目背景原文。
+- 题名为“拆拼互换”，但操作正文未明确写出哪一个拆下的阀装到哪一处；两阀来源、目标位置及适用条件需核定。
+- 装配第②项的“四个固定螺栓”和第④项的“四个连接螺栓”是否同一组，图片没有说明。
+- 原图写“板手”，整理后的工具名称可核定为“扳手”；19号、8号规格按原文保留。
+- 原文“阀体座”和“阀座”两种称呼均保留，正式编排可在术语核定后统一。
+- 文本要求清洗阀体表面以及各油管接头，不能只表现阀体变色而遗漏接头。
+- 图片没有给出安装位置照片、背景图、讲解视频、油污贴图或互换后的试验判据；相关素材需另行配置。

+<p>环境：本地 127.0.0.1:6180、局域网 192.168.31.168:6180，现有 /api 网关代理。账号类型：管理员，教员预览。</p>
+<p>原因：准备校验失败会恢复模型，但未恢复当前步骤已完成的机构动作。005 没有补充操作台，原恢复逻辑因此跳过了已打开的盒盖。</p>
+<p>修复：恢复当前步骤已完成的动作不再依赖补充操作台。拒绝末项操作时，仅回退该项动作，保留开盖状态和动作进度。</p>
+<ul>
+<li><a href="before-fix.json">修复前：真实鼠标操作复现失败</a>，盒盖从打开 100° 复位为关闭。</li>
+<li><a href="after-fix.json">修复后：新模型任务 116 全流程</a>。开盖后触发准备提示，校验已开盖姿态、开关回退、操作序号及证据数量；连续保存两次后，真实拖动开关完成第 5 步。</li>

+<p>执行：<code>node tools/bridge-controls-live.mjs</code>，新任务启用 <code>TASK_IDS=116 EXECUTE=1 PREPARE_SAFETY=1 LATE_PREPARATION=1 MANUAL_OCCLUSION_TOOLS=1</code>；原有任务设置 <code>TASK_IDS=86</code>，不启用 LATE_PREPARATION（原任务没有该准备拦截）。</p>
+<p>前端验证：<code>node scripts/virtual-training-formal-route.contract.test.mjs</code>、<code>pnpm run build</code>。本次没有创建任务、发布新版本或写入学员成绩；预览准备信息仅用于本次预览，测试只留下本目录报告与截图。</p>
