登机桥遮篷用开闭装置 技术领域
本发明涉及一种登机桥， 尤其是涉及一种登机桥遮篷用开闭装置。 背景技术
新型飞机与普通飞机不同之处在于，在新型飞机外壳机首过渡区内往往具有一很大的 弯角。 由于现有的登机桥是结合普通飞机的外壳特点进行开发设计的， 因此， 当把现有的 登机桥用于新型飞机上时，在登机桥的遮篷与新型飞机的外壳之间往往会形成一缝隙， 从 而导致整体密封不严。 在遇到雨雪天气时， 雨雪往往通过该缝隙打湿旅客的衣服和行李， 更有甚者， 雨雪有时也会通过该缝隙进入到飞机内部。
为了克服上述技术问题， 一些开发厂商进行了很多尝试， 例如中国专利 CN200510063002.6公开一种飞机乘客舷梯或飞机登机桥的密封装置， 该密封装置包括一 跨装在连接地板上的遮蓬，遮蓬的一个开口端具有柔性框架， 另一开口端设置在一门形框 架上。在该专利申请案中， 门形框架固定在舷梯或登机桥上。在遮蓬移出时柔性框架贴合 在飞机外壳上。密封装置还设有一展开和合拢遮蓬的操纵装置， 操纵装置包括一受驱动的 可旋转轴， 通过所述轴可对至少一个和柔性框架连接的牵引装置进行卷绕和退绕。操纵装 置具有两个隔开设置的铰接臂， 它们分别具有一个上臂和一与上臂铰接的下臂，上臂在遮 蓬的顶棚区域铰接在门形框架上，而下臂铰接在柔性框架上，还设有用来展开遮蓬的展开 装置。虽然该装置可以实现与新型飞机入口的良好密封， 但这种密封装置结构复杂， 使用 寿命比较短。 另外， 在柔性框架与飞机入口相接后， 由于人或货物离开飞机等原因， 飞机 内部所受重力减小，飞机机身整体向上移动，从而飞机外壳往往会与遮蓬发生挤压或碰撞， 由于该专利申请案中的上臂和下臂均为刚性臂， 在飞机外壳与遮蓬发生挤压或碰撞时， 其 之间产生的相互作用力， 往往会使飞机外壳发生变形或损伤。因此有必要对这种形式的登 机桥进行结构上改进。 发明内容
本发明的目的是提供一种登机桥遮篷用开闭装置， 该开闭装置结构简单，其在飞机外 壳与遮篷发生挤压或碰撞时， 可保护飞机外壳不会因挤压或碰撞变形或损伤，且其可与轮 廓曲率变化较大的飞机入口进行可靠的密封。
为实现上述技术目的， 本发明采用下述技术方案- 一种登机桥遮篷用开闭装置， 该遮篷固定在登机桥地板上方且其具有两开口端， 其一 开口端设置有用以伸出与飞机外壳贴合的柔性框架， 另一开口端与登机桥的门形框架连 接， 该开闭装置设置在该柔性框架与该门形框架之间， 其中， 该登机桥遮篷用开闭装置包 括设置在该门形框架上的至少一套伸缩臂装置， 所述伸缩臂装置均包括：

优选的是， 如图 4所示， 该登机桥遮篷用开闭装置包括分别设置在该门形框架 1 1两 侧的两套伸缩臂装置。
推进器 33优选电动推进器， 当然也可选择气动推进器或其他电动推进器的可替代形 式。 为叙述的方便， 本发明在以下叙述时， 如无特指， 所称的推进器 33即为电动推进器。 推进器 33设置在上臂 31与下臂 32之间， 其包括伸缩杆 331、容纳伸缩杆 331的机体 332 以及电机 333， 伸缩杆 331与该机体 332分别位于该推进器 33的两端， 在电机 333的作 用下， 伸缩杆 331可在机体 332内进行伸缩动作。 位于推进器 33的一端的该机体 332与 上臂 31相连接， 其连接位置优选靠近上臂 31与门形框架 12铰接位置。位于推进器 33另 一端的伸缩杆 331与下臂 32相连接， 其连接位置优选靠近下臂 32与上臂 31铰接位置。 电机 333与一控制系统 （图未示）连接， 该控制系统通过控制电机 333的动作， 用以完成 推进器 33的伸缩杆 331伸缩动作。
该控制系统可以是手控开关， 计算机控制装置等， 在该控制系统的控制下， 设置在推 进器内部的电机能实现正反转， 从而驱动伸缩杆 331在机体 332内完成停止伸出和 /或缩 回动作。 该控制系统内部设有一预定值， 当该遮篷 1与飞机外壳之间的作用力超过该预定 值的时候， 该控制系统控制推进器 33使该伸缩杆 331停止伸出和 /或回缩。
上述结构， 在控制系统的控制下， 推进器 33的伸缩杆 331从机体 332内伸出时， 其 推动下臂 32展开， 由于下臂 32与柔性框架 11相连， 柔性框架 11在下臂 32的推动下， 带动遮篷 1一起向远离门形框架 12方向运动， 遮篷 1展开。 推进器 33的伸缩杆 331， 往 机体 332内缩回时， 下臂 32在该伸缩杆 331的拉动下， 带动柔性框架 11向靠近门型框架 12方向运动， 遮篷 1收回。
参见图 3和图 4， 本发明在上臂 31和地板 2之间设置一可伸缩的推杆 8。该推杆 8― 端与靠近上臂 31与下臂 32铰接处的上臂 31端相连， 另一端与靠近门形框架 12的地板 2 连接， 当然， 该端也可与靠近遮篷 1与门形框架 12连接处的门形框架 12相连。 该推杆 8 用以与推进器 33相配合推动上臂 31展开。
在上臂 31展开时， 推进器 33工作， 推杆 8配合工作， 推动上臂 31展开， 上臂 31带 动下臂 32动作， 使柔性框架 1 1展开与飞机外壳接触。
参见图 5且结合图 4可知，本发明在靠近上臂 31和下臂 32铰接处设置有过压保护装 置 4， 在遮篷 1与飞机入口对接过程中如与飞机外壳发生碰撞或飞机外壳与遮篷发生挤压 时，该过压保护装置 4可缓冲该遮篷 1与飞机外壳发生碰撞所产生的冲力或飞机外壳与遮 篷因挤压而产生的应力，进而防止了飞机外壳因与遮篷 1碰撞或挤压而引起的外壳变形或 损坏情况的出现。
该过压保护装置 4包括弹性部件和信号控制部件，该弹性部件与该信号控制部件相配 合用以缓冲遮篷 1与飞机外壳发生碰撞所产生的作用力力，并可缓冲飞机外壳与遮篷 1因 挤压而产生的应力。 该过压保护装置 4与控制系统相连接， 以使当该遮篷 1与飞机外壳之 间的作用力超过该预定值的时候， 该控制系统控制推进器 33使该伸缩杆 331停止伸出和 / 或回缩。
该弹性部件包括弹簧 50和螺杆 51， 上臂 31和下臂 32通过连接轴 41相铰接。 在该 上臂 31上从其与连接轴 41的连接处沿其靠近该连接轴 41的端头方向开有供连接轴 41滑 动的长槽 42。 在上臂 31靠近该连接轴 41的端头处固定有安装座 43 , 安装座 43与上臂 31连接端开有滑孔 431。 该螺杆 51穿过弹簧 50且其一端穿过该滑孔 431与安装座 43滑 动连接， 另一端与连接轴 41相连接。
信号控制部件包括两位限位开关 60以及与该两位限位开关 60相连的摆杆 600， 该两 位限位开关 60设置在上臂 31靠近连接轴 41的一端，该两位限位开关 60与登机桥控制系 统连接， 并限制摆杆 600使其具有第一角度位置和第二角度位置， 当摆杆 600位于第一角 度位置时， 登机桥控制系统会发出停止信号， 推进器 33停止伸出， 遮篷 1停止展幵， 当 摆杆 600位于第二角度位置时， 登机桥控制系统会发出收回信号， 推进器 33缩回， 上臂 31和下臂 32缩回， 收回遮篷 1。 在连接轴 41轴端设置有靠轮 410， 摆杆 600的自由端设 置有滚轮 601， 滚轮 601与靠轮 410相抵靠。
当人或货物从遮篷 1与飞机入口相密封的通道下机后，飞机整体机身由于内部所受重 力减小， 其整体机身将向上移动， 在移动时， 机身外壳往往会与遮篷 1发生挤压或碰撞， 在与遮篷 1挤压或碰撞时， 飞机机身外壳与遮篷 1之间产生一作用力， 在该作用力达到预 定值时， 在该作用力作用下， 下臂 32以连接轴 41为中心沿所受作用力方向发生偏转， 其 偏转时带动连接轴 41沿图 5所示长槽 42向下滑移， 连接轴 41滑移时， 带动设置在其轴 端的靠轮 410—起下移， 由于滚轮 601与靠轮 410相抵靠， 在该靠轮 410的作用下， 该滚 轮 601偏转， 与该滚轮 601连接的摆杆 600随之发生摆动， 当其摆动到由两位限位开关限 制的第一角度位置时， 登机桥控制系统会发出停止信号， 推进器 33停止伸出， 遮篷 1停 止展开； 当其摆动到由两位限位开关限制的第二角度位置时， 登机桥控制系统发出收回信 号， 推进器 33缩回， 上臂 31和下臂 32缩回， 收回遮篷 1。 上臂 31和下臂 32通过这样 反复调整自身位置， 使遮篷 1始终与飞机入口保持良好密封， 同时， 由于其可以缓冲飞机 机身外壳与遮篷 1之间因碰撞或挤压产生的作用力， 因此， 其可以保护飞机外壳不会因碰 撞或挤压而产生变形或损伤。
参见图 6， 本发明的过压保护装置第二实施例与第一实施例的结构相似， 其亦包括弹 性部件和信号控制部件， 弹性部件包括弹簧 50和螺杆 51， 信号控制部件包括两位限位开 关 60以及与该两位限位幵关 60相连的摆杆 600, 该两位限位开关 60与登机桥控制系统 连接， 并限制摆杆 600使其具有第一角度位置和第二角度位置， 当摆杆 600位于第一角度 位置时， 登机桥控制系统会发出停止信号， 推进器 33停止伸出， 遮篷 1停止展开， 当摆 杆 600位于第二角度位置时， 登机桥控制系统发出收回信号， 推进器 33缩回， 上臂 31和 下臂 32缩回， 收回遮篷 1。 其不同之处在于， 该弹性部件和信号控制部件设置在靠近下 臂 32和柔性框架 1 1铰接处， 其中， 螺杆 51穿过弹簧 50且其一端与柔性框架 1 1相连接， 另一端与设置在摆杆 600上的滚轮 601相抵靠， 在与摆杆 600相连的两位限位开关 60的 作用下， 滚轮 601带动摆杆 600进行摆动。
当人或货物从遮篷 1与飞机入口相密封的通道下机后，飞机整体机身由于内部所受重 力减小， 其整体机身将向上移动， 在移动时， 机身外壳往往会与遮篷 1发生挤压或碰撞， 在与遮篷 1挤压或碰撞时， 飞机机身与遮篷 1之间产生一作用力， 在该作用力的作用下， 螺杆 51沿所受作用力方向移动， 推动与之相顶靠的滚轮 601带动摆杆 600动作， 该摆杆 600动作时， 两位限位开关 60起作用， 当摆杆 600摆动到由两位限位开关 60限制的第一 角度位置时， 登机桥控制系统会发出停止信号， 推进器 33停止伸出， 遮篷 1停止展开； 当其摆动到由两位限位开关 60限制的第二角度位置时， 登机桥控制系统发出收回信号， 推迸器 33缩回， 上臂 31和下臂 32缩回， 收回遮篷 1。 上臂 31和下臂 32通过这样反复 调整自身位置， 使遮篷 1始终与飞机入口保持良好密封， 而又不会在遮篷 1与飞机之间的 碰撞或挤压产生的作用力下导致飞机外壳变形或损伤。
在本发明以上各实施例中， 门形框架 12处设置有弹性缓冲机构， 该弹性缓冲机构优 选弹性材料，其位置位于在上臂 31处于收回状态时与该上臂 31相对应的门形框架 12处， 该弹性材料优选橡胶等材料。 当上臂 31 在推进器 33 的作用下收回时， 如其与门形框架 12发生碰撞， 该弹性材料可对上臂 31起到弹性缓冲作用， 从而提高本发明的使用寿命。
由技术常识可知，本发明可以通过其它的不脱离其精神实质或必要特征的实施方案来 实现。 因此， 上述公开的实施方案， 就各方面而言， 都只是举例说明， 并不是仅有的。 所 有在本发明内或在等同于本发明的范围内的改变均被本发明包含。
