Description

传统岸桥外置下小车的起升钢丝绳缠绕系统及起升机构 技术领域
本发明涉及新型高效集装箱装卸设备技术领域，特别是传统岸桥外置下小车的起升钢丝绳缠绕系统及起升机构。
背景技术
目前国内外应用最多的为传统单小车岸桥，采用单小车装卸集装箱的方式，单机装卸效率达到极限，仍不能满足码头对装卸效率的要求。在面对大型集装箱船时，多采用增加岸桥作业数量的方式提高船时装卸效率，受制于岸桥作业间距，简单增加岸桥作业数量已不能满足船运客户对船时效率的需求。若是直接将传统单小车岸桥废弃，新建更换更先进的岸桥系统，则面临着巨额投资成本以及现有资源的极大浪费。因此为了降低投资成本、提高传统岸桥装卸效率，需要突破传统思维，对传统岸桥进行升级改造。首先将现有岸桥大梁改造成双梯形四轨道大梁，即大梁内侧铺设有原有上小车运行轨道，原有上小车在大梁内侧的轨道上行走；在大梁外侧铺设有新增下小车运行轨道，新增下小车倒挂在大梁外侧的轨道上行走。
在升级改造过程中，新增下小车的起升机构以及起升钢丝绳缠绕系统的安装位置以及布置方式面临一定的技术难题，主要体现在：传统岸桥机房空间有限，若是新增机房又面临改造空间受限、结构复杂、成本较高的问题；传统岸桥原有上小车结构简单、尺寸小，简易的起升钢丝绳缠绕系统便可实现其升降，但是新增下小车结构较复杂，因此还需要设计一套保证下小车稳定起升的钢丝绳缠绕系统。
发明内容
本发明的目的在于，提供一种传统岸桥外置下小车的起升钢丝绳缠绕系统及起升机构，通过巧妙地结构设计，无需进行机房改造便可实现起升机构等的安置问题，同时设计了一套新增下小车的起升钢丝绳缠绕系统，保证下小车稳定起升，以带动下小车吊具的起升动作。
为解决上述技术问题，本发明采用如下的技术方案：
传统岸桥外置下小车的起升钢丝绳缠绕系统及起升机构，岸桥机房内布置有上小车的上小车起升机构。传统岸桥外置下小车的起升钢丝绳缠绕系统及起升机构包括下小车起升机构和下小车起升缠绕系统，下小车起升机构通过下小车起升缠绕系统带动下小车吊具起降。下小车起升机构也置于岸桥机房内，其中下小车起升机构包括下小车起升机构A、下小车起升机构B和浮动联轴节，下小车起升机构A与下小车起升机构B之间通过浮动联轴节相连，其中浮动联轴节水平设于上小车起升机构的后方，下小车起升机构A和下小车起升机构B分别 设于上小车起升机构的左侧和右侧。其中浮动联轴节的设置可以保证下小车起升机构A、下小车起升机构B运行同步，防止两个机构运行不同步导致带动的下小车吊具发生倾转问题，这是下小车起升机构的一大创新；另外，由于机房的空间有限，为了安置新增的下小车起升机构A、下小车起升机构B，还不需要新建机房、降低改造成本，浮动联轴节起到很好地连贯作用，将浮动联轴节小尺寸设置，左右分别连接下小车起升机构A与下小车起升机构B，充分利用原有机房的剩余空间，提高空间利用率，还能保证新增下小车稳定运行。
前述的传统岸桥外置下小车的起升钢丝绳缠绕系统及起升机构，所述下小车起升机构A包括起升卷筒A、电机、减速器，其中电机的一侧同轴连接有减速器，电机的另一侧轴连接有起升卷筒A；所述下小车起升机构B包括起升卷筒B、电机、减速器，其中电机的一侧同轴连接有减速器，电机的另一侧轴连接有起升卷筒B。
前述的传统岸桥外置下小车的起升钢丝绳缠绕系统及起升机构，所述下小车起升缠绕系统包括下小车起升缠绕组A和下小车起升缠绕组B，下小车起升机构A通过下小车起升缠绕组A带动下小车吊具起降，同时下小车起升机构B通过下小车起升缠绕组B带动下小车吊具起降。
