Description

一种用于岸桥吊具上架及吊具的插接装置 技术领域
本发明属于港口码头技术领域，具体地说，是涉及一种用于岸桥吊具上架及吊具的插接装置。
 背景技术
目前的岸边集装箱起重机，吊具使用频繁且故障率高，需要周期性的更换吊具，更换吊具的一个重要环节便是插头的连接和分离，但吊具及上架所采用的插头普遍采用均分分布的插针，在实际使用中，由于持续的震动，容易造成连接松动。
 技术问题
随着自动化集装箱码头的发展，吊具功能更加强大，岸桥与吊具所用到的光纤及通信线路越来越多，均匀分布的插针在实际使用中存在电磁干扰问题，容易造成吊具信号不稳定的故障。
 技术解决方案
本发明的目的在于提供一种用于岸桥吊具上架及吊具的插接装置，具有插头与插座连接导向定位功能、连接后自锁功能、分离时自动解锁功能以及避免电磁干扰的功能，能够减少插头故障，使岸桥吊具保持最高效的作业效率，解决现有吊具插接装置存在的上述技术问题。
为解决上述技术问题，本发明采用以下技术方案予以实现：
提出一种用于岸桥吊具上架及吊具的插接装置，包括插头组件和插座组件，所述插头组件安装于岸桥吊具上架，所述插座组件安装于吊具，所述插头组件，包括插头壳体、牵引电磁铁、导向柱、横向压缩弹簧、纵向张力弹簧、定位钢球、分隔板、锥形柱、吸盘和插针；所述导向柱固定于所述插头壳体内，所述插针排布于所述导向柱周围；所述分隔板间隔排布于所述导向柱与所述插头壳体内壁之间，将所述插针分隔排布在M个插针区域内；所述纵向张力弹簧设置于所述导向柱内部，其下端连接所述吸盘，其上端布设所述牵引电磁铁；所述吸盘下端连接所述锥形柱；所述锥形柱顶端连接所述横向压缩弹簧，所述横向压缩弹簧的末端连接所述定位钢球；所述插座组件，包括插座壳体、分隔板套孔、导向柱套孔、钢球定位孔和插孔；所述导向柱套孔固定于所述插座壳体内，所述插孔布设于所述导向柱套孔周围；所述分隔板套孔间隔排布于所述导向柱套孔和所述插座壳体内壁之间， 将所述插孔分隔排布在M个插孔区域内，且所述M个插孔区域与所述M个插针区域对应；所述导向柱套孔的底端外围开设有钢球定位孔，其中，所述M为大于等于2的正整数。
进一步的，所述插针根据电气功能划分为M类，每一类排布于一个插针区域内。
进一步的，所述M为3，3个插针区域内的插针分别为通信线路插针、吊具泵动力回路插针和吊具控制回路插针。
进一步的，所述纵向张力弹簧与所述吸盘的外径相同。
进一步的，所述纵向张力弹簧与所述吸盘的外径与所述导向柱的内径相同。

进一步的，由于插针被分隔板分隔为若干插针区域，使得每个插针区域可以设置同一类型的插针，并将不同电气类型的插针分隔在不同区域，避免了彼此间的电磁干扰，减少插头故障，满足岸桥吊具更换、上架切换过程的高效、安全、可靠的要求。

 本发明的最佳实施方式
下面结合附图对本发明的具体实施方式作进一步详细的说明。
一种用于岸桥吊具上架及吊具的插接装置，应用于岸桥吊具上架和吊具中，包括插头组件1和插座组件2，插头组件1安装于岸桥吊具上架的下部，插座组件2安装于吊具上，依靠岸桥起升机构的驱动力使插头组件跟随吊具上架上下运行，同时借助吊具导向槽的辅助作用，避免吊具插头连接时，插头跟随吊具上架晃动；在吊具插头与插座连接过程中，插头则在其导向柱和插座中的导向柱套孔的引导下继续连接。
具体的，如图1和图2所示，插头组件1包括插头壳体101、牵引电磁铁102、导向柱103、横向压缩弹簧108、纵向张力弹簧107、定位钢球106、分隔板104、锥形柱109、吸盘110和插针105；导向柱103固定于插头壳体101内，插针105排布于导向柱103周围；分隔板104间隔排布于导向柱103与插头壳体101内壁之间，将插针105分隔排布在M个插针区域Q内；纵向张力弹簧107设置于导向柱103内部，其下端连接吸盘110，其上端布设牵引电磁铁102，具体的，其上端连接一牵引柱，牵引电磁铁102绕设于该牵引柱上；吸盘110下端连接锥形柱109；锥形柱109的顶端连接横向压缩弹簧108，横向压缩弹簧108的末端连接定位钢球106。
如图3和图4所示，插座组件2包括插座壳体200、分隔板套孔201、导向柱套孔202、钢球定位孔204和插孔203；导向柱套孔202固定于插座壳体200内，插孔203布设于导向柱套孔202周围；分隔板套孔201间隔排布于导向柱套孔202和插座壳体200内壁之间， 将插孔203分隔排布在M个插孔区域P内，且M个插孔区域P与M个插针区域Q对应；导向柱套孔202的底端外围开设有钢球定位孔204，这里的M为大于等于2的正整数。
插座组件和插头组件对接时，导向柱103插入导向柱套孔202，在导向柱103插至导向柱套孔202底端时，导向柱103顶端的定位钢球106落入导向柱套孔202底端开设的钢球定位孔204中，进而横向压缩弹簧108将定位钢球106挤压固定在钢球定位孔204中，实现插头组件与插座组件的自锁；在分离时，为牵引电磁铁102通电，使得纵向张力弹簧107受牵引电磁铁102的牵引而收缩，从而带动锥形柱109跟随纵向张力弹簧107运行，横向压缩弹簧108两侧的力逐渐减小使得定位钢球106从钢球定位孔204中脱离，从而实现插头组件与插座组件的自动解锁。
可见，基于本发明提出的用于岸桥吊具上架及吊具的插接装置，插头组件和插座组件这种自锁式和自动解锁式的结构，能够避免作业震动引起插头松脱的故障。
本发明提出的插头组件中，插针105被分隔板104分隔为M个插针区域Q，这使得每个插针区域Q内可以设置同一电气类型的插针，将不同电气类型的插针分隔在独立的区域内，被分隔板104隔离，彼此间不会产生电磁干扰，减少插头故障，满足岸桥吊具更换、上架切换过程的高效、安全、可靠的要求。
相应的，在插座组件中，插孔203被分隔板套孔201分隔为若干插孔区域P，在插头组件与插座组件插接时，每个插孔区域P与插头组件中的插针区域Q相对应，使得插针104插入插孔204中。
在本发明实施例中，划分了3个插针区域Q和插孔区域P，3个插针区域内的插针分别通信线路插针、吊具泵动力回路插针和吊具控制回路插针；纵向张力弹簧108与吸盘110的外径相同，且纵向张力弹簧107与吸盘110的外径与导向柱103的内径相同，使得二者与导向柱103内壁紧密贴合，横向压缩弹簧108受导向柱103内壁限制呈压缩状态；优选的，锥形柱109的外径小于纵向张力弹簧107的外径。
应该指出的是，上述说明并非是对本发明的限制，本发明也并不仅限于上述举例，本技术领域的普通技术人员在本发明的实质范围内所做出的变化、改型、添加或替换，也应属于本发明的保护范围。
