Description

过渡车钩用平衡装置
技术领域
本发明涉及一种过渡车钩用平衡装置， 尤其涉及一种 15/13号车钩适配密接车钩的过渡 车钩用平衡装置。
背景技术
过渡车钩是用于调车作业、 列车回送与救援的重要装置， 在轨道车辆领域， 15/13 号车 钩适配密接车钩的过渡车钩应用非常普遍。
现有的过渡车钩没有平衡装置， 在现场应用过程中， 由于 15/13号车钩连挂间隙较大， 安装后过渡车钩的密接钩端会在自重作用下出现 "低头"现象， 使得密接钩端不易与正式车 钩连挂， 必须增大连挂速度才能连挂成功。这样不仅容易对密接车钩造成损伤， 且可能对车 体存在一定的不利影响。
调车作业现场， 部分调车员采用临时加木片或者铁片垫在 15/13钩连挂面下侧， 能够对 "低头"现象起一定的缓解作用， 但此方法不易操作， 且无法从根本上解决问题。
发明内容
本发明的目的在于提供一种主要用于 15/13号车钩， 可有效避免过渡车钩出现 "低头" 现象的过渡车钩用平衡装置。
本发明的技术方案是： 一种过渡车钩用平衡装置， 该过渡车钩用平衡装置设置于过渡车 钩的上端面上， 过渡车钩用平衡装置包括设置在过渡车钩上的转轴、 转杆和顶座； 转杆包括 上端板和下端板， 上端板和下端板之间设置有一斜台凸起， 斜台凸起位于下端板的侧面上， 斜台凸起为一片装凸起结构， 以转杆的上端板和下端板为参照， 斜台凸起的纵向为向转杆外 倾斜结构，转杆的一端安装在转轴上，转杆的另一端安装有销轴，销轴上还安装有活节螺栓， 转杆可绕转轴转动， 并通过销轴与活节螺栓铰接： 顶座上开有通孔， 活结螺栓穿过顶座的通 孔， 活节螺栓的末端固定安装有螺母， 螺母和顶座的通孔之间设置有弹簧， 弹簧的直径大于 顶座通孔的直径。
优选的是： 转杆上设置有转轴连接孔， 通过转轴连接孔与转轴连接； 转杆上还设置有销 轴连接孔， 通过销轴连接孔与销轴连接； 所述的销轴连接孔有多个， 多个销轴连接孔延转杆 长度方向纵向排列。
优选的是：斜台凸起在水平方向上的位置位于转轴连接孔的水平位置和销轴连接孔的水 平位置之间。
优选的是：转轴连接孔在水平方向上的位置位于斜台凸起的水平位置和销轴连接孔的水 平位置之间。
优选的是： 通孔为长圆孔。
优选的是： 通孔处设置有沉孔。
优选的是： 活节螺栓的末端安装螺母的位置处有多组销孔， 销孔中穿入开口销， 螺母安 装在开口销的前端， 通过开口销对螺母进行固定。
本发明的有益效果是：
( 1 ) 本发明提供的过渡车钩用平衡装置安装在过渡车钩与 15/13号车钩连挂接触的 S 面处， 平衡装置上的斜台凸起与 15/13号车钩相接触， 将过渡车钩连挂时 "低头"产生的向 下的力的作用通过过渡车钩用平衡装置上的斜台凸起作用于 15/13号车钩，可有效避免车钩 连挂时出现的 "低头"现象， 使过渡车钩安装后处于水平。
( 2 ) 在车钩拉伸状态下， 该平衡装置将会被拉伸， 由于弹簧进一步压缩， 转杆绕转轴 逆时针转动， 其凸起部位超出 S面尺寸减小， 直至转杆轮廓全部位于 S面外侧， 避免平衡装 置在拉伸状态下受力， 平衡装置的使用寿命长。
( 3 ) 该平衡装置可通过调整螺母的位置或调整活节螺栓在销轴连接孔上的安装位置调 整弹簧的预紧力， 当 15/13号车钩具体型号变化时， 该平衡装置仍然适用。
( 4) 转杆上转轴孔、 销轴孔和斜台凸起的水平相对位置可以灵活设置， 适应不同车钩 的结构。
( 5 ) 顶座上的通孔采用长圆孔， 适应活结螺栓运动过程中的运动轨迹需求， 还可以在 通孔处设置沉孔， 采用沉孔将活节螺栓的位置固定， 使活结螺栓可相对稳定的运动。

具体实施方式
以下结合附图对本发明的实施例进行具体说明。 雄例 1
如图 1至图 4所示， 该过渡车钩用平衡装置设置于过渡车钩 1的上端面上， 过渡车钩用 平衡装置包括设置在过渡车钩上 1的转轴 2、、 转杆 4和顶座 7; 转杆 4包括上端板 11和下 端板 12， 下端板 12上设置有一斜台凸起 13， 斜台凸起 13位于下端板的侧面上， 斜台凸起 13为一片装凸起结构， 以转杆 4的上端板 11和下端板 12为参照， 斜台凸起 13的纵向为向 转杆 4外倾斜结构， 转杆 4的一端安装在转轴 2上， 转杆 4的另一端安装有销轴 5， 销轴 5 上还安装有活节螺栓 6， 转杆 4可绕转轴 2转动， 并通过销轴 5与活节螺栓 6铰接； 顶座 7 上开有通孔， 活结螺栓 6穿过顶座 7的通孔， 通孔为长圆孔， 通孔处设置有沉孔， 长圆孔可 以满足活节螺栓 6运动过程中活动范围的需求， 沉孔可以对活结螺栓 6进行固定。活节螺栓 6的末端设置有螺母 9，螺母 9和顶座 7的通孔之间设置有弹簧 10，弹簧 10的直径大于顶座 7通孔的直径。
转杆 4上设置有转轴连接孔 14， 通过转轴连接孔 14与转轴 2连接； 转杆 4上还设置有 销轴连接孔 15， 通过销轴连接孔 15与销轴 5连接； 销轴连接孔 15有 1个， 多个销轴连接孔 15延转杆 4长度方向纵向排列。斜台凸起 13在水平方向上的位置位于转轴连接孔 14的水平 位置和销轴连接孔 15的水平位置之间， 这种结构尤其适用于 15/13号车钩适配过渡车钩的 过渡车钩， 因为这种过渡车钩上设置有与转轴连接孔 14的位置适配的安装孔。
活节螺栓的末端安装螺母的位置处有多组销孔 16， 销孔 16中穿入开口销， 多组销孔 16 在活节螺栓 6的螺栓轴 18上纵向排列， 螺母 9安装在开口销的前端， 通过开口销对螺母进 行固定。
如图 5所示， 图 5是本发明工作时俯视结构示意图， 工作时， 过渡车钩用平衡装置安装 在过渡车钩 1的水平端面上， 斜台凸起 13靠近车钩钩舌 S面侧， 斜台凸起 13为倾斜片状结 构， 其在安装状态下的纵向尺寸超过过渡车钩钩舌与 15/13号车钩钩头 S面的相接面。
工作状态下， 15/13号车钩固定安装于机车上， 将过渡车钩 1与 15/13号车钩连接。 由于 过渡车钩 1较 15/13号车钩较重， 因此过渡车钩 1将会在连挂的过程中产生 "低头"现象。 在 过渡车钩 1 "低头" 的过程中， 由于转杆 2在纵向尺寸高出 S面， 斜台凸起 13将与 15/13号车 钩钩舌的 S面相接触， 在连挂时起到导向作用。过渡车钩 1与 15/13号车钩连挂后， 由于斜台 凸起 13的存在， 斜台凸起 13对 15/13号车钩钩舌的 S面起到向下的力的作用， 过渡车钩 1与 15/13号车钩 S面上侧间隙被压缩， 即通过解钩迫使密接钩端 "抬头"， 过渡车钩 1自重的作 用与斜台凸起 13力的作用相互抵消， 从而使得过渡车钩 1安装后处于水平状态。 过渡车钩 1在拉伸工况时， 15/13号车钩钩舌 S面作用于转杆 4的斜台凸起 13上，使转 杆 4有相对于转轴 2逆时针旋转的趋势， 由于顶座 7内孔为长圆孔， 使得转杆 4可以带动活 节螺栓 6运动， 在此过程中弹簧 10被压缩， 同时转杆 4继续绕转轴 2转动， 直至转杆 4的 轮廓完全超出过渡车钩 1与 15/13号车钩钩舌相接触的 S面， 此时两侧 S面直接作用， 避免 了平衡装置在拉伸状态下直接受力， 从而保证了转轴 2受力较轻， 且弹簧 10的压缩量稳定 在一定值， 避免由于疲劳降低其使用寿命。
在使用过程中， 由于弹簧 10老化或者 15/13号车钩的具体型号变化， 可能存在需要调 整弹簧 10预紧力的情况， 此时可通过调整开口销在活节螺栓 6上的安装位置， 将其安装在 不同的销孔 16内， 从而调整螺母的位置来实现调节弹簧 10预紧力。
转杆 4上的销轴连接孔 15的个数大于 1个， 使用过程中， 由于弹簧 10老化或者 15/13 号车钩的具体型号变化， 需要调整弹簧 10预紧力的情况下， 也可以通过调整销轴 5在不同 的销轴连接孔 15中的安装位置， 从而调整活节螺栓 6的安装位置， 实现调整弹簧 10的预紧 力的目的。
使用完成后， 将密接钩端解钩， 然后将过渡车钩 1从 15/13号车钩取下， 此时在回复力 作用下弹簧 10恢复原长， 从而带动活节螺栓 6， 并进一步带动转杆 4转动，直至转杆 4恢复 到原始位置， 整个平衡装置完全回到初始状态， 无需人工干预。
難例 2
由于不同型号车钩的具体形状也不同， 因此与实施例 1不同， 又对转杆的结构进行了进 一步改进，转轴连接孔 14在水平方向上的位置位于斜台凸起 13的水平位置和销轴连接孔 15 的水平位置之间。 这种设计适用于其他类型的过渡车钩， 转轴连接孔 14的位置可根据车钩 的具体形状设计。
