Description

说明书 带有伸缩桥面和井字形垂直多级升降桥柱的移动斜拉桥 技术领域
[0001] 本发明公开一种带有伸缩桥面和井字形垂直多级升降桥柱的移动斜拉桥， 用于交通运 输、 军事运输和抢险救灾等， 属于交通运输和抢险救援机械装置技术领域。
背景技术
[0002] 目前， 用于交通运输、 军事运输、 抢险救灾等突发事件， 快速通过断桥、 沟壑、 峡谷、 河流等尚无带有伸缩桥面和垂直升降桥柱并可移动使用斜拉桥式的机电一体化行走设备。
[0003] 通过断桥、 沟壑、 峡谷、 河流的装置目前只有军事运输通过河流时靠浮桥来实现， 断 桥、 沟壑、 峡谷就无能为力了， 其缺点是只能在河流上使用， 铺设时间长等缺点， 遇有突发 情况或军事行动， 只能靠机械一点一点的铺设。 尚无可移动快速到达对岸的行走机械设备， 当遇有自然灾害、 军事行动时， 由于没有实用的机械设备， 而使人员及物资得不到及时抢救， 而受到重大损失， 军事行动不能快速到达目的地， 失去战机。
发明内容
[0004] 本发明提供一种带有伸缩桥面和井字形垂直多级升降桥柱的移动斜拉桥， 目的在于解 决交通运输、 军事运输、 自然灾害运输等突发情况下断桥、 沟壑、 峡谷、 河流快速通过运输 问题。
[0005] 为实现本发明的目的而采用的技术方案如下：
在底盘上设有一层不动的主桥面， 主桥面上侧设有主桥面滑轨与第一伸缩桥面下侧的第一伸 缩桥面下侧滑轨构成滑动连接副， 第一伸缩桥面上侧设有第一伸缩桥面上侧滑轨与第二伸缩 桥面的下侧第二伸缩桥面下侧滑轨滑接构成滑动连接副， 以此类推， 上一层桥面与下一层桥 面构成多级桥面的滑动连接副； 伸缩液压马达设在主桥面的下侧， 通过闭环链条和承载压轮 与主桥面下侧的导向链轮中的正时针导向链轮、 逆时针导向链轮构成闭环结构， 为桥面伸缩 提供动力； 闭环链条与第一伸缩主桥面后端固定连接带动第一伸缩桥面伸缩； 第一伸缩桥面 的正时针导向绳轮、 逆时针导向绳轮通过闭环链条构成闭环链轮机构， 链条分别与第二伸缩 桥面后端固定、 主桥面前端固定连接， 构成双向往复循环闭环桥面伸缩机构；
主桥面两侧设有数个垂直多级液压升降桥柱构成井字形斜拉桥架，斜拉桥架上方装有滑轮组， 底盘尾部设有副桥， 副桥两侧装置有斜拉绞盘组， 通过斜拉绳、 滑轮组分别于各个伸缩桥面 两侧的伸缩桥面承载导轮连接构成多级斜拉承载机构； 在副桥及尾端的第二伸缩桥面的一端分别设有可折叠的副桥引桥、 引桥、 支撑装置。
[0006] 本发明在使用时， 将斜拉桥移动到指定地点， 在液压系统作用下展开底盘两侧承载平 衡支腿， 启动不动主桥面下侧伸缩液压马达工作， 双向往复循环闭环伸缩机构反时针转动， 第二伸缩桥面下侧滑轨与第一伸缩桥面上侧滑轨和第一伸缩桥面下侧滑轨与主桥面上侧滑轨 同时滑移； 第二伸缩桥面、 第一伸缩桥面沿其滑轨向前有序同时滑行， 将各个桥面展开； 同 时， 主桥井字形垂直多级液压升降桥柱在液压系统作用下升起， 副桥两侧斜拉承载液压绞盘 钢丝绳依序展开， 通过主桥井字形垂直多级液压升降桥柱两侧上的两组升降桥柱滑轮组与第 二伸缩桥面两侧承载导轮， 第一伸缩桥面两侧承载导轮相互铰接的多级动滑轮单元组合作用 依序展开， 实现桥面平稳向前展开和桥柱同步有序升起后， 放下副桥尾端的副桥引桥和伸缩 桥面最前的引桥， 人员、 物资、 车辆即可通过副桥引桥到达主桥面， 通过主桥面依次到达第 一伸缩桥面、 第二伸缩桥面、 引桥， 到达河流、 断桥、 沟壑、 峡谷对岸。
[0007] 人员、物资、车辆通过结束后， 工作人员将第二伸缩桥面前端引桥和支撑装置收起后， 启动设在主桥面下侧伸缩液压马达工作， 双向往复循环闭环伸缩机构正时针转动， 在伸缩液 压马达作用下， 第二伸缩桥面下侧滑轨与第一伸缩桥面上侧滑轨和第一伸缩桥面下侧滑轨与 主桥面上侧滑轨同时反向滑移； 第二伸缩桥面、 第一伸缩桥面沿其滑轨向后有序同时滑行， 将桥面收回。 同时， 主桥井字形垂直多级液压升降桥柱在液压系统作用下降， 副桥两侧斜拉 承载液压绞盘钢丝绳依序收回， 通过主桥井字形斜拉桥架两侧上的滑轮组与伸缩桥面两侧承 载导轮， 第一伸缩桥面两侧承载导轮相互铰接的多级动滑轮单元组合作用依序收回， 实现桥 面平稳向后收回和桥柱同步有序下降后， 收回副桥尾端的副桥引桥， 在液压系统作用下收起 底盘两侧承载平衡支腿， 结束工作。
[0008] 本发明的积极效果在于： 采用多级可伸缩的桥面结构， 通过井字形斜拉桥架支撑伸缩 桥面， 能够快速搭建起桥梁通道， 使人员、 物资、 车辆短时间内实现河流、 断桥、 沟壑、 峡 谷快速通行； 具有装置结构简单， 搭建迅速， 安全可靠， 能够移动， 实用性强等特点。 可广 泛应用于抢险救灾、 突发事件及军事战争等情况下的交通运输， 短时间内实现河流、 断桥、 沟壑、 峡谷快速通行， 为军事运输、 抢险救援赢得了时间。
