登机桥电缆输送装置
技术领域
本发明涉及一种登机桥， 尤其涉及登机桥中的电缆输送装置。 背景技术
现有的三通道登机桥， 第一通道的尾端与登机桥的桥墩相连， 第二通道可伸缩地套设 在第一通道上， 第三通道可伸缩地套设在第二通道上， 在登机桥完全展开时， 第一通道的 首端与第二通道的尾端相接，第二通道的首端与第三通道的尾端相接，其中的电缆输送通 过两套拖链装置来实现， 这两套拖链装置的拖链一般分别为垂直布置和水平布置， 所谓垂 直布置是指拖链链节的转动铰接中心线与水平支撑面相垂直， 也就是： 拖链链节的侧面与 水平支撑面相贴合； 水平布置是指拖链链节的转动铰接中心线与水平支撑面相平行， 也就 是- 拖链链节的侧面与水平支撑面相垂直。这种结构的登机桥电缆输送装置， 一方面， 由 于垂直布置的拖链在运动时与水平支撑面之间存在滑动摩擦，运动阻力大，拖链容易损坏， 使得整个装置的使用寿命较短； 另一方面， 由于在登机桥的通道伸縮时， 垂直布置的拖链 装置与水平布置的拖链装置必须配合， 而造成整个装置的外观尺寸较大、可装载的电缆较 少。 发明内容
本发明要的目的在于克服现有技术的不足， 而提出一种使用寿命较长、外观尺寸小并 且可装载的电缆多的登机桥电缆输送装置。
为了实现上述目的，本发明公开了一种登机桥电缆输送装置，用于三通道的登机桥中， 该登机桥电缆输送装置包括第一拖链装置和第二拖链装置，第一拖链装置包括第一拖链和 用于承载电缆和放置该第一拖链的第一拖链架，第二拖链装置包括第二拖链和用于承载电 缆和放置该第二拖链的第二拖链架，第一拖链架设置在第一通道的下方且包括第一固定端 和第一自由端， 第一固定端与第一通道的尾端相连， 第一自由端可沿设置于第二通道的第 一导轨作相对运动，第一拖链可在第一拖链上水平展开且两端分别铰接于第一拖链架和第 二通道； 第二拖链架设置在第二通道的下方且包括第二固定端和第二自由端，第二固定端 与第二通道的尾端相连并随第二通道而移动，第二自由端可沿设置于第三通道的第二导轨 作相对运动， 第二拖链可在第二拖链架上水平展开且两端分别铰接第二拖链架和第三通 道， 在第二通道缩回而套在第一通道上时，第二拖链架回缩于第一拖链架中并与第一拖链 架叠合。
与现有技术相比， 本发明的登机桥电缆输送装置， 完全采用水平布置的拖链， 可减少 运行阻力， 延长零部件的使用寿命， 而第二拖链架可收缩入第一拖链架并与之叠合， 使整 个装置的结构更紧凑并能装载更多的电缆， 而拖链架采用桁架结构更可节省制造用料。 附图说明

图 9是图 5中的第一拖链架和第二拖链架相配合的截面示意图。 具体实施方式
如图 1和图 5所示， 登机桥包括第一通道 1、第二通道 2、第三通道 3， 在登机桥运行 时， 第二通道 2、 第三通道 3可根据登机桥所需的展开长度按比例伸縮。 登机桥完全展开 时， 第一通道 1的首端（即图 1中右手侧的端部）与第二通道 2的尾端（即图 1中左手侧 的端部）相接， 第二通道 2的首端（即图 1中右手侧的端部）与第三通道 3的尾端（即图 1 中左手侧的端部）相接， 根据需要， 可适当设置第一通道 1、 第二通道 2、 第三通道 3 的尺寸大小， 使得在在登机桥缩回时第一通道 1、 第二通道 2和第三通道 3能够叠合、 套 装在一起。第一通道 1的下方设有用于输送电缆的第一拖链装置， 第二通道 2的下方设置 有用于输送电缆的第二拖链装置， 每套拖链装置都包括拖链架和对应的拖链， 图 1中示出 了第一拖链装置的拖链架 4和第二拖链装置的拖链架 5， 而未示出相应的拖链， 图 5中示 出了第一通道 1的尾端与登机桥的桥墩 6相连，拖链架 4的 A端铰接到第一通道 1的尾端， 拖链架 4的 B端可沿设置在第二通道 2的导轨移动， 拖链架 5的 C端与第二通道 2的尾 端连接， 拖链架 5的 D端可沿第三通道 3上的导轨移动。
在一优选实施例中， 拖链架 4的一端铰接到登机桥的第一通道 1的尾端上， 另一端则 以拖链架 5上的主梁 7为导轨， 可相对拖链架 5或通道 2而移动， 以确保电缆能够按需要 进行伸缩。优选地， 主梁 7为型钢。而为了防止拖链架 4与主梁 7脱离， 可在拖链架 4的 B端设置限位装置 8， 该限位装置 8包括， 但不限于是： 双轮缘滚轮。 当然， 本发明并也 不限于以主梁 7为导轨， 例如： 在一些情况之下， 可在第二通道 2下方设置型钢作为拖链 架 4的导轨。
类似地， 拖链架 5的一端连接到第二通道 2的尾端上， 可随第二通道 2动作。 另一端 则以固定在通道 3下方的型钢 10为导轨。 同样地， 为防止拖链架 5与导轨 10脱离， 在拖 链架 4的 D端部设置限位装置 9。
如图 2所示， 电缆从拖链架 4的 A端输入，沿着第一拖链架 4水平延伸且部分电缆进 入第二通道 2 (未示出） ， 其余电缆部分通过拖链 11进入拖链架 5的 C端， 然后沿着第 二拖链架 5水平延伸， 在通过拖链 12到达第三通道 3 (未示出）， 在登机桥展开时， 拖链 11和拖链 12被拉伸。
为有效地縮短拖链和电缆的长度， 拖链 11与拖链架 4的连接点£、 拖链 12与拖链架 5的连接点 F最好分别位于拖链架 4和拖链架 5的中点。 也就是说， 拖链 11的一端最好 连接到拖链架 4的中点， 另一端连接到第二通道 2; 拖链 12的一端最好连接到拖链架 5 的中点， 另一端连接到第三通道 3。
为了节省材料， 可适当设计拖链架 4、 5的长度， 使拖链架 4的 B端在登机桥完全展 幵时基本与拖链架 5的 C端重合，拖链架 5的 D端在登机桥完全展开时基本与第三通道 3 的尾端重合。
如图 3所示， 在登机桥展开时， 第三通道 3牵引拖链 12， 第二通道 2牵引拖链 11。 在登机桥缩回时， 拖链 12可在第三通道 3的作用下缩回到拖链架 5中， 拖链 11可在第二 通道 2的作用下缩回到拖链架 4中。
为了减少运行阻力、 延长零部件的寿命， 拖链 11和拖链 12均为水平布置。
如图 4和图 9所示， 为了使结构紧凑， 可适当设置拖链架 4和拖链架 5的大小， 使拖 链架 5在登机桥缩回时与拖链架 4叠合， 即拖链架 5位于拖链架 4的空腔内。优选地， 拖 链架 4和拖链架 5的中心线是重合的。
如图 6所示，拖链架 4采用带斜杆的桁架结构，可在拖链架 4的 B端设置图 8所示的 限位装置 8， 拖链架 4的前部， 也就是由 A端到 E端的那段， 其截面形状为如图 9所示的 上端开口的槽形。
如图 7所示， 拖链架 5采用带斜杆的桁架结构， 其主梁 7是型钢， 该主梁可作为拖链 架 4的 B端的轨道， 同样地， 可在拖链架 5的 D端设置图 8所示的限位装置 8， 拖链架 5 前部， 也就是由 C端到 F端的那段， 其截面形状为如图 9所示的上端幵口的槽形。
如图 8所示， 导轨 7和限位装置 8相配合， 拖链架的端部在限位装置 8以及其它约束 件的作用下， 能沿着导轨 7移动而不会脱离导轨 7。
如图 9所示， 登机桥动作时， 拖链架 5在拖链架 4的空腔内伸缩。 通常要求拖链 11 的宽度要大于拖链 12的宽度。 这是因为： 一方面， 拖链展开时会下垂， 拖链架 4的支撑 面 13可用来支撑拖链 11， 拖链架 5的支撑面 14可用来支撑拖链 12， 以抵御拖链下垂； 另一方面， 拖链 11比拖链 12需要传输更多的电缆， 从而需要更大的空间。
