Description

一种轨道客车前舱翻转式开闭机构 技术领域
本发明属于轨道车辆设备技术领域，尤其涉及一种利用推杆动力及重力因素实现整体前舱开闭功能，可靠性高，制造、维护成本低的用于轨道客车前舱的翻转式开闭机构。
背景技术
现有地铁、城际列车等传统车辆的车钩等设备直接外露或用螺栓固定头部端盖，其外观较差或拆装困难，费时费力，同时空气阻力较大，设备易受损。。
现有高速列车开闭机构为旋转式，头部端盖沿车体纵向对称面分为左右两块，其打开关闭功能类似门扇的开闭，使用气缸数量多，相应的结构、电气管路和控制系统也较复杂，形式单一，体积、重量较大，成本较高，需电源和压缩空气接口，灵活性较差。
发明内容
本发明的目的在于克服现有技术存在的缺点，寻求设计一种利用推杆动力及重力因素实现整体前舱开闭功能，可靠性高，制造、维护成本低的用于轨道客车前舱的翻转式开闭机构。
为了实现上述目的，发明采用的技术方案为：
一种轨道客车前舱翻转式开闭机构，包括机构组成、解锁钢丝绳、气动控制箱；所述机构组成包括承载骨架、气缸、同步杆、导槽、导轨、头罩支架、旋转销、滑板、同步轮、气弹簧、打开位锁舌、关闭位锁舌、关闭位传感器、打开位传感器、中间位传感器、中间位传感器压板、导槽轮；所述气动控制箱与气缸连接；
所述导槽包括直线槽、弧形槽和U型槽三部分，直线槽与弧形槽相连，U型槽位于弧形槽的内侧；所述导槽和导轨固定安装于承载骨架上，导轨位于导槽的下方；所述滑板的端部与导轨匹配，滑板相对于导轨前后直线运动；所述气缸固定于承载骨架上，气缸出杆与滑板连接；
所述气弹簧的尾端通过销轴固定于滑板上，气弹簧的前端通过销轴与头罩支架连接，气弹簧的尾端和前端均可绕销轴转动，提供头罩旋转时的助力；所述头罩支架的中部通过旋转销固定于滑板上，头罩支架可绕旋转销旋转；头罩支架的端部设有导槽轮，导槽轮与导槽相匹配；
所述同步杆的两端呈可转动的固定于左右两侧的承载骨架上方，同步杆的下延伸部设有滑槽；所述同步轮安装于滑板上，同步轮与同步杆下延伸部的滑槽相匹配；
所述关闭位锁舌安装于导槽的直线槽末端上方，锁闭弹簧位于关闭位锁舌上方，关闭位锁舌与解锁钢丝绳连接；关闭位锁舌的上方设有关闭位传感器；关闭位锁舌通过解锁钢丝绳抬起实现解锁，抬起时压缩锁闭弹簧，通过锁闭弹簧落下复位，实现加锁；所述打开位锁舌安装于承载骨架上，且与导槽的U型槽相对，打开位传感器与打开位锁舌对应安装于承载骨架上；所述中间位传感器压板固定在头罩支架上，并可随头罩支架旋转，中间位传感器固定在滑板上，中间位传感器压板的端部与中间位传感器对应；打开位传感器、中间位传感器和关闭位传感器分别与气动控制箱连接。
优选的是，所述解锁钢丝绳的末端与手动旋钮连接，手动旋钮位于司机室内；
优选的是，所述滑板的侧面还设有止挡，当头罩支架和头罩在气弹簧及重力的共同作用下，头罩支架与止挡接触时，导槽轮与U型槽对准；
优选的是，所述气动控制箱与气缸通过气路管连接；打开位传感器、中间位传感器和关闭位传感器分别通过气路管与气动控制箱连接；

优选的是，所述关闭位锁舌上方的关闭位传感器安装与承载骨架上；
优选的是，所述头罩支架的前端与整体头罩连接。
本发明的原理为：当需要打开整体头罩时，拉动解锁钢丝绳，使关闭位锁舌抬起，此时关闭位锁舌触碰关闭位传感器，关闭位传感器将信号传输到气动控制箱，然后气动控制箱控制给气缸动作，气缸出杆向前推出，带动滑板沿导轨向前直线滑动，此时导槽轮在导槽的直线槽里滑动，头罩支架不能旋转，头罩支架和头罩随滑板向前直线运动，到达图3所示位置；
到达图3所示位置时，导槽轮到达导槽的弧形槽位置，此时头罩在重力和气弹簧的作用力下向下翻转，会到达图4所示位置；
到达图4所示位置时，中间位传感器压板随头罩支架旋转，碰触中间位传感器，此时中间位传感器传输信号给气动控制箱，控制气缸出杆缩回，从而带动头罩到达最终打开位，如图5所示。此时导槽轮进入导槽的U型槽内，并挤开打开位锁舌，到达打开位置并自动锁闭。
当需要关闭头罩时，在车下手动掰动打开位锁舌，使打开位锁舌触碰打开位传感器，通过气动控制箱控制气缸出杆伸出，到达图4所示位置。此时需要人工抬动头罩翻转到达图3所示位置，使中间位传感器压板随头罩支架旋转，会碰到并碰触中间位传感器，传输信号给气动控制箱，控制气缸出杆缩回，到达图2所示位置，关闭位锁舌自动锁闭。
本发明的有益效果为：
本发明在有限且不规则的空间内，利用气动及重力因素实现整体前舱的开闭功能，形式 新颖，结构简单实用，可靠性高，同步性能好，制造、维护成本低。
