申请号为CN201210389260.3的中国专利公开了一种登机桥升降同步检测系统，其采用两个拉绳编码器分别安装于登机桥通道两侧的升降立柱上，通过登机桥通道两侧升降立柱上的拉绳编码器检测的升降立柱高度差值，对登机桥通道两侧升降的同步性进行检测，进而通过控制系统的控制信号对通道两侧的升降立柱进行调整，以达到两侧平衡的效果。

具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本公开将全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。
测高装置实施方式
参阅图1，图1中代表性地示出了能够体现本公开的原理的测高装置安装于登机桥的主视图。在该示例性实施方式中，本公开提出的测高装置是以作为测量登机桥的高度监测装置为例，进一步地，是以拉绳编码器120作为测距机构为例进行说明的。本领域技术人员容易理解的是，为将本公开提出的测高装置配置为其他设备的高度或距离监测装置，而对下述的具体实施方式做出多种改型、添加、替代、删除或其他变化，这些变化仍在本公开提出的测高装置的原理的范围内。
如图1所示，在本实施方式中，本公开提出的测高装置用于安装在例如一登机桥的待测设备上，以在其升降过程中进行高度监控。本公开提出的测高装置主要包括测高套管110、测距机构、厢体130以及下安装座140和上安装座150。配合参阅图2至图4所示， 图2中代表性地示出了图1中的A部放大图；图3中代表性地示出了图1中的B部放大图；图4中代表性地示出了本公开提出的测高装置安装于登机桥的侧视图。以下结合上述附图，对本公开提出的测高装置的个主要组成部分的结构、连接关系和功能进行详细说明。
如图1和图4所示，在本实施方式中，待测设备主要包括主体以及升降机构(即登机桥的通道210以及升降立柱220)。其中，升降机构连接于主体以对其提供一升降功能。具体而言，该升降机构可以设于主体的侧面、底部或顶部。
如图2和图3所示，在本实施方式中，测高套管110竖直设置且包括套设配合的两根套管，分别为第一套管111和第二套管112。具体而言，第一套管111相对固定，即不随升降机构(或主体)的升降而相应升降。第二套管112可升降地套设于第一套管111的外周，即第一套管111伸入第二套管112，且配置为随升降机构(或主体)的升降而相应升降的结构。其中，在测高套管110处于起始状态时，即升降机构未工作且主体处于起始位置时，第一套管111的顶端未凸出于第二套管112的顶端。承上，本实施方式中是以第二套管112能够相对第一套管111向上升起的设计为例进行说明的，本领域技术人员容易理解的是，根据本公开的设计构思，调整上述两根套管的位置或者改变其移动的方向，均不脱离本公开的原理的范围。
需要说明的是，在本实施方式中，测高套管110的上述结构组成和连接方式仅为示例性的，其旨在以较简单的结构适应例如登机桥的待测设备。在其他实施方式中，测高套管110的结构和连接方式亦可根据需要灵活调整。例如，测高套管110的套管数量可以为三根或以上，例如类似多级液压缸的结构，且需保证各套管的位于其中一端的一根不随升降机构的升降而相应升降，且其余各套管随升降机构的升降而相应地多级伸缩升降。又如，第一套管111亦可套设于第二套管112的外周，即第二套管112亦可伸入第一套管111。再如，可将第二套管112相对固定，而将第一套管111可伸缩升降地套设于第二套管112，均不以此为限。
进一步地，如图2和图3所示，在本实施方式中，测高套管110还包括两组滑套113。具体而言，第一套管111的外径略小于第二套管112的内径，以供具有一定厚度的滑套113的设置。其中一组滑套113设于第一套管111的顶部的外壁，其中另一组滑套113则设于第二套管112的底部的内壁。通过上述滑套113的设置，能够使第二套管112相对第一套管111的伸缩升降更加顺畅。在其他实施方式中，上述滑套113亦可为多组，例如在设有滑套113的两位置沿轴向方向分别设置多组滑套113，并不以此为限。再者，当第二套管112套设于第一套管111之内时，第一套管111的顶部的内壁设有滑套113，且第二 套管112的底部的外壁设有滑套113。
如图1、图2和图4所示，在本实施方式中，厢体130固定在测高套管110的底部，即第一套管111的底部，用以容纳测距机构。其中，厢体130的与第一套管111连接的位置上开设有通孔，以供测距机构测量测高套管110的高度信息。具体而言，在本实施方式中，第一套管111的底端伸入厢体130的通孔，且第一套管111的底端管口与测距机构的位置相互对应。在其他实施方式中，厢体130的结构并不唯一，且可不使用厢体130，即测距机构独立设置于测高套管110底部，具体的技术方案可根据实际需求灵活调整，并不以此为限。
进一步地，在本实施方式中，厢体130与第一套管111的连接处可以设置密封结构，以增强对厢体130内的测距机构的保护。再者，厢体130可以设计为具有维修门131的结构，方便维修者对其内部的测距机构的维护。
如图2和图3所示，在本实施方式中，测距机构优选地配置为拉绳编码器120，其包括本体121以及拉绳122。具体而言，本体121设于厢体130内，即位于测高套管110的底部，拉绳122一端可收放地缠绕于本体121内部，另一端穿过测高套管110的内腔并连接于测高套管110的顶部，例如第二套管112内腔的顶部。在其他实施方式中，当厢体130设于第二套管112的顶部，即本体121位于测高套管110的顶部时，拉绳122一端可收放地缠绕于本体121内部，另一端则穿过测高套管110的内腔并连接于测高套管110的底部。
进一步地，如图2所示，考虑到结构的整体高度和现有拉绳编码器120的拉绳122长度，在本实施方式中，拉绳122是通过一根连杆114间接地连接于测高套管110的顶部。具体而言，连杆114的顶端连接于测高套管110的顶部，例如第二套管112内腔的顶部，且连杆114穿设于第一套管111之内。连杆114的底端大致位于第一套管111的底部开口处，且连接于拉绳编码器120的拉绳122，从而使拉绳122间接连接于测高套管110，以随其伸缩而拉出或收回。较佳地，在本实施方式中，连杆114的该底端连接有一导向块115，该导向块115与第一套管111滑动配合，且优选为与第一套管111的内腔匹配，从而在连杆114带动拉绳122伸缩的过程中，利用导向块115对连杆114在第一套管111内的滑动进行导向，避免晃动的发生，而进一步提升测高装置的稳定性。
基于上述结构，当升降机构驱动主体升降时，第二套管112随主体或升降机构相对第一套管111伸缩升降，即测高套管110的高度发生变化，从而带动拉绳122由本体121拉出的长度发生变化。测距机构则根据测得的测高套管110的高度信息而得出主体或升降机 构的高度信息。
在此应注意，附图中示出而且在本说明书中描述的测高装置仅仅是能够采用本公开原理的许多种测高装置中的一个示例。应当清楚地理解，本公开的原理绝非仅限于附图中示出或本说明书中描述的测高装置的任何细节或测高装置的任何部件。
登机桥实施方式
在本实施方式中，本公开提出的登机桥主要包括通道210、行走机构、升降立柱220以及本公开提出的测高装置。以下结合图1至图4，对本公开提出的登机桥的各主要组成部分的结构、连接关系及功能进行详细说明。
如图1和图4所示，在本实施方式中，升降立柱220连接于通道210以对其进行升降。具体而言，升降立柱220为两根或两组，且分别设于通道210的两侧。每根升降立柱220包括内导管221以及外导管222，内导管221底部固定于登机桥的行走机构上，外导管222可升降地套设于内导管221之外，且连接于通道210的侧壁。其中，通过外导管222相对于内导管221的升降，升降立柱220能够驱动通道210升降。
如图4所示，在本实施方式中，登机桥包括一个测高装置，该测高装置对应于两根升降立柱220的其中之一，仅设置一个测高装置可进一步简化结构、降低成本。当然，测高装置亦可为分别对应两根升降立柱220的两个，且在两根升降立柱220上分别设置一个测高装置的设计，能够实现对两根升降立柱220升降高度的分别测量，即实现对通道210两侧升降高度的分别测量，从而进一步实现升降立柱220升降通道210时两侧升降高度的同步测量控制。其中，测高装置的测高套管110可选用上述的包括第一套管111以及第二套管112的结构，且第一套管111底部与内导管221的底部相对固定，第二套管112的顶部与外导管222的顶部相对固定。具体而言，在本实施方式中，测高套管110还包括下安装座140以及上安装座150，下安装座140相对固定于内导管221的下端部，第一套管111的底部(即测高套管110的底部)固定于下安装座140，上安装座150相对固定于外导管222的上端部，第二套管112的顶部(即测高套管110的顶部)固定于上安装座150。
进一步地，由于本实施方式中的测高装置是包括厢体130，且厢体130设于测高套管110底部并容设有拉绳编码器120。因此，基于上述结构，厢体130固定在下安装座140上，且第一套管111的底部固定于厢体130的顶部。当拉绳编码器120的安装有本体121的厢体130位于升降立柱220的底部时，能够进一步便于维修人员对测高装置的检查和维修。在其他实施方式中，根据厢体130的设置与否以及厢体130与测高套管110的相对位置，可对测高套管110与下安装座140或上安装座150的连接方式(例如直接或间接的方 式)进行灵活选择，并不以此为限。
需要说明的是，测高装置的测高套管110与登机桥的连接位置并不限于上述实施方式的设计。如图4所示，登机桥的位于两根升降立柱220下方的位置设有横梁230，则下安装座140可以安装在该横梁230上，由于横梁230与升降立柱220的内导管221为相对固定的结构，则固定在下安装座140上的第一套管111与升降立柱220的内导管221亦为相对固定的结构。
承上，对于测高装置适配于登机桥时的各部件的安装位置，并不以本实施方式为限，仅需保证拉线编码器能与升降立柱220同步或对应同步运动即可，例如测高装置的测高套管110的顶部除了安装于升降立柱220外导管222的顶部外，还可以安装于外导管222的底部或其他部分，均能起到测高的作用。又如，将拉绳编码器120的拉绳122端与本体121的安装位置进行调换，同样能起到测高的作用。
在此应注意，附图中示出而且在本说明书中描述的登机桥仅仅是能够采用本公开原理的许多种登机桥中的一个示例。应当清楚地理解，本公开的原理绝非仅限于附图中示出或本说明书中描述的登机桥的任何细节或登机桥的任何部件。
基于上述对本公开提出的测高装置及登机桥的示例性说明，以适配于登机桥为例，本公开提出的测高装置的大致工作过程为：当登机桥处于低位时，拉线编码器根据拉绳的伸出长度确定登机桥处于低位时的高度。当升降立柱外导管相对内导管上升时，外导管带动测高套管的第二套管上升，从而带动拉绳向上拉伸，拉绳编码器则根据拉绳长度的变化判断登机桥所处的高度，以达到测高的效果，反之亦然。
综上所述，本公开提出的测高装置，通过将测距机构安装在测高套管中，使得测高装置在监测过程中，免受障碍物的干扰，且在例如雨雪天气的特殊环境下不易产生误测现象，从而提升测高装置的准确性和稳定性。
本公开提出的登机桥，通过使用本公开提出的测高装置，利用测高套管与测距机构的配合设计，将测高装置由例如升降立柱的其他结构中独立出来。与现有技术相比，本公开有效降低了例如拉绳编码器的测距机构安装的复杂度。同时，基于测高套管的防护作用对测高装置的稳定性和准确性的提升，进一步优化了登机桥的高度检测和升降控制的效果。
虽已参照几个典型实施例描述了本公开，但应理解，所用的术语是说明和示例性、而非限制性的术语。由于本公开能以多种形式具体实施而不脱离发明的精神或实质，所以应理解，上述实施例不限于任何前述细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为权利要求所涵盖。
