说明书 多用途载重举升工作平台或 /和组合式桥梁结构 技术领域
[1] 本发明涉及一种载重举升物体的工作平台， 也可以作为组装桥梁的模块结构。
它适用于下列领域： 起重机、 载重举升机、 升降机、 舞台设备、 活动房屋的活 动基础、 立体停车设备、 立体仓储物流设备、 搬运设备、 桥梁结构。
背景技术
[2] 目前大多数的起重机、 举升机、 升降机或其他搬运设备， 都是起升吋工作轨迹 为垂直升降的工作方式， 被吊重物会来回摆动， 水平稳定性差； 并且只配有一 个工作平台， 这对它们的使用范围造成了一定限制。 此外这些设备工作吋耗能 是非常大的。 另一方面， 桥梁建设已实现了模块化生产、 组装， 但仍然需要架 桥机或起重机将结构件精确吊装以及大量的人工协同操作。 并且施工周期长， 建设和拆除难度大一直都是桥梁建设需要解决的问题。 此外大部分的组合式的 快速架桥结构或机械仅能作架桥之用， 不能作其他用途！
对发明的公开
发明内容
[3] 本发明目的在于克服上述不足， 提供一种工作轨迹为曲线的载重举升设备， 它 可以提供两平台协调工作或单平台独立工作。 杆状结构铰接和支撑工作平台， 工作平台相对于框架做曲线运动， 并可停在运行轨迹上的任意位置。 两平台工 作面积大大超过目前常见的单平台作业的装载举升机、 升降机、 起重机以及其 它举升搬运设备。 它可以不晃动地装载建筑材料、 汽车、 矿石、 船艇、 活动房 屋、 集装箱等大体积的物体， 也可以作为组合式或组装式的桥梁结构。
[4] 此外工作平台转换运动过程中， 在工作平台的前后端可选择安装无线发射、 接 收装置。 在设定的反射距离内， 如 1.5米以内发现障碍物， 则发出停止运行信号 ， 设备停止运行， 可保证在设备运行中工作平台不会与周边障碍物或人相碰。
[5] 可选择安装的带弹簧按键新型阻档装置可以防止设备运行中重物滑落。 此外， 本设备的框架底座四角上可选择安装轮子， 使之具备移动性。 可移动到任意地 点。 在四个立柱的内部设有尖桩， 可用于松软地基 (如室外沙土地)上的固定。
[6] 本设备在每个工作平台装有自动识障监测装置的对面一侧可选择安装接触后急 停装置， 保障当工作平台的这一侧运行中接触到障碍物吋， 设备紧急停止。
[7] 当操纵单台或多台本设备， 使每台设备的工作平台处于同一水平位置或接近同 一水平位置 （允许平台之间存在一定的高度差） 并首尾连接各台设备， 两端配 以斜坡， 可以快速构建桥梁， 如图 11所示。 当然也可以与现有的已知桥梁结构 混合排列组成桥梁， 如图 11-1所示。 可以在接缝处铺设弹性物质垫层， 以减少路 面的颠簸。 允许平台之间存在一定的高度差。 平台除了做成水平面的平台， 也 可以根据实际需要制成凸凹状的曲面平台。 这种工作平台做桥梁的结构使得组 装和拆除桥梁都比较容易，由于结构与结构之间的自由度大， 因此抗震性能好。
[8] 本发明的设计方案如下：
一种载重举升工作平台或 /和是桥梁组装构件。 它包括框架、 上下层工作平台、 平台驱动机构、 从动及助动机构、 电气控制装置、 可选择安装的自动识障监测 装置、 可选择安装的轮子及尖桩、 可选择安装的阻档装置和接触后急停装置； 它提供一种单平台工作或双平台协调工作的载重起升设备，工作平台可以绕杆状 结构一端与框架直接或间接的连接点做曲线运动， 并可停在运行轨迹上的任意 位置。
[9] 工作平台借助驱动机构以及从动及助动机构全部或部分结构或者是这二者之一 的全部或部分结构的推动作用下运动， 使工作平台绕杆状结构直接或间接与框 架的连接点作曲线轨迹运动。 本设备具体结构如下：
[10] (1)框架， 分为两种类型： 按顶部装有定滑轮的立柱数目分为， 四立柱型和两中 立柱型。
[11] 1.四立柱型框架； 它包抬底座 11和与其垂直的四根立柱 12、 横梁 13， 立柱的顶 部装有定滑轮 14， 在靠近底部位置装有导向滑轮 15，跨在两根横梁 13之间的中间 支撑结构 16。 其中中间支撑结构 16可根据实际载重量的大小， 选择安装或不安 装。 中间支撑结构的形状可以是倒 U型或门字型。 如图 1所示。 四立柱型框架比 两中立柱型框架结构安全性高， 受力更合理。
[12] 2.两中立柱型框架： 与四立柱型框架主要区别在于用两根顶部带两个定滑轮的 中立柱 121代替了四根顶部带一个定滑轮位于设备四周的立柱， 其余结构与四立 柱框架相同、 如图 11-1和图 11所示、 这种框架结构最经济， 但是承载受力过多地 集中在两根中立柱上， 因此对中立柱的材料强度和结构强度要求高。
[13] (2)工作平台： 包括上层工作平台 21、 下层工作平台 22。 上下层工作平台可通过 与从动及助动机构的联系， 更好地实现互动。 当只需要一个平台单独工作吋， 可以只装配和使用从动及助动机构的一部分结构， 如图 244、 图 245所示。 工作 平台与杆状结构铰接， 它的工作轨迹是曲线， 并可停在运行轨迹上的任意位置 。 工作平台的形状可以有多种形状， 如椭圆形， 圆形， 最基本的是长方形。 工 作平台既可以是水平面的工作平台， 也可以根据实际需要， 制成有凸凹状的非 水平面的平台， 这样的工作平台具有一定的曲线效果。 例如当举升船艇吋， 工 作平台可以制成有圆弧状内表面的平台或釆用网状结构形式， 以利于停泊船只， 如图 223和图 224所示。 同一设备的装配的两个工作平台尺寸可以有大有小， 以 适应特殊需要。 平台也可以作为活动房屋的活动基础， 如图 244和图 234所示。 作为舞台设备吋， 平台可以设计成加高加厚的长板状结构， 如图 7-1所示， 以阵 列方式拼接成大舞台。
[14] 需要指出的是为适应某些场合下的起重需要， 平台可简化为横梁、 挂钩、 吊环 或专用的夹具和索具，如图 225、 图 226、 图 227和图 228所示。 如果对被举升的重 物移动的稳定性要求不高， 即允许移动中货物来回摆动， 则可以使用一根或两 根并列的杆状结构做为起升机构来举升重物， 此吋工作平台被简化为吊钩、 吊 环、 或专用的夹具和索具。 如图 228、 图 229所示。
[15] 以上这些例子都是工作平台的变化形式之一。
[16] (3)驱动机构： 如图 1所示，包括减速电机 31、 传动带 32、 钢丝卷筒或收链机构 33
、 一端与 33相连， 另一端固定在工作平台上或者是端部固定并环绕在半圆形支 杆轮缘凹槽中的钢丝绳或链条 34-1和 34-2组成 （34-1、 34-2既可以选用钢丝绳， 也可以选用链条、 传动带、 绳索） ， 当载重量很大吋， 可以将 34-1、 34-2设置成 多股钢丝绳或链条。 其中， 减速电机 31通过传动带带动卷筒 33转动， 卷筒上缠 绕的钢丝绳 43-1、 43-2随之伸长或收紧， 牵引相应的平台 21、 22运动。 由于某种 限制条件或需要， 除了自身配有驱动机构的方式外， 也可以由外部提供相应的 驱动机构， 而设备本身不再安装驱动机构； 还可以釆取与用其他外部动力源合 用的方式实现运动。 比如作为桥梁结构吋， 结构本身非常沉重， 而且设备本身 只需运动一、 二次即可， 大部分吋间都是静止或停止状态。 在这种情况下， 仅 靠设备本身自备的驱动机构既不经济也可能不够用， 它需要由外部配置的大型 驱动机组提供动力。
[17] (4)从动及助动机构： 此机构跟随平台运动并帮助平台运动， 解决了机械学中连 杆机构在低速运动中工作不流畅及可能出现的反转和失效情况， 并能在工作平 台之间转化和传递动能与势能。
[18] 由于选择杆状结构的类型不同， 分为两种类型的从助及助动机构， 任一种类型 的从助及助动机构都可以独立使用于本设备中， 也能够同吋混合或相互替换使 用于本设备中。 还可以以其中一种类型的部分结构使用于本设备中。 若两种类 型机构混合使用， 则更多地提供安全传动的保障， 提高工作效率。
[19] 杆状结构指能够活动连接平台与框架的稳定结构， 它的一端与平台铰接并支撑 平台， 另一端直接或间接与框架活动连接； 杆状结构包括下文中提到的直角形 杆、 半圆形杆、 圆形杆、 椭圆形杆、 半椭圆形杆、 水滴形杆、 半水滴形杆、 倒 水滴形杆、 半倒水滴形杆。 其中， 半椭圆形杆、 椭圆形杆如图 2-20、 2-21所示;水 滴形杆、 半水滴形杆、 倒水滴形杆、 半倒水滴形杆如图 2-22、 2-23、 2-24、 2-25 所示，它们可以增大或减小设备的起动力矩。 根据工作平台实际载重量增加， 杆 状结构也可以釆用建筑工程或机械工程当中的多种受力结构形式， 如加强筋， 桁架结构， 如图 2-16-1、 2-16-2、 2-16-3中所示三种桁架结构形式。 杆状结构可 以制成不等长的， 以适应特殊用途， 比如需要有倾斜度的工作平台。 每个工作 平台 1根以上的杆状结构 41支撑， 常用形式为 4或 6根杆状结构支撑， 如果实际载 重量很大， 就需要增加杆状结构的数量。 例如选择 6根杆状结构支撑工作平台， 可以均匀地分配负荷， 减小每根杆的横截面积， 如图 2-1所示。
类型 1 : 包括直角形的杆状结构 41 (简称直角形杆 41) 、 链轮 42、 轴承座 43、 链条 44。 杆状结构的一端通过轴承座 43固定在框架上， 链轮 42与杆状结构 41一 端钢性连结， 链条 44环绕在链轮 42上， 各构件的装配组合关系如图 3-1所示。 每 个工作平台至少由 1根以上的杆状结构 41支撑， 本文为简化构图， 简要说明原理 以后均以 4根杆状结构支撑工作平台为例进行叙述或绘图。 杆状结构可以选用图 2-1、 图 2-2、 图 2-3所示的直角形的杆中任一种形式。 杆斜撑 46的作用主要起加 强结构强度的作用。 类型 1中要求杆的材料力学性能要很好， 足够承受链轮对支 杆的扭矩作用。 此机构的作用在于把一个工作平台的主动运动传递到另一个工 作平台， 使之做协同运动。 另一工作平台的协同运动符合物理学中物体的势能 与动能相互转化的原理， 从而通过从动及助动机构又可以把一部分动能传递回 做主动运动的一侧工作平台， 使驱动机构不需输出很大的动力就可以使工作平 台运动， 达到节约能源的目的。 杆或杆状结构、 链轮、 链条、 钢丝绳、 上下层 工作平台的空间布置结构示意图如图 4所示。
类型 2: 包括非直角形的杆状结构 41 (具体包括半圆形杆、 圆形杆、 直角形杆 、 椭圆形杆、 半椭圆形杆、 水滴形杆、 半水滴形杆、 倒水滴形杆、 半倒水滴形 杆） ，端部固定并环绕在轮缘凹槽上的钢丝绳或链条 18、 19、 20 (18、 19、 20既 可以选用钢丝绳， 也可以选用链条、 传动带或绳索； 其中钢丝绳、 绳索的端部 需要固定在轮缘上， 链条和传动带可以选择环绕或端部固定方式。 ） ， 轴承座 4 3、 轴承 50。 轴 50穿过杆状结构中部的轴孔， 通过轴承座 43固定在框架上； 钢丝 绳或链条 18、 19、 20缠绕在杆状结构的轮缘凹槽上， 各构件的装配组合关系如 图 3-2所示。 下面以半圆形杆或圆形杆为例介绍， 半圆形或圆形杆可以选用图 2-5 、 2-6、 2-7、 2-8、 2-18、 2-19、 2-27、 2-28、 2-29中的任一种， 其中 2-6、 2-61是 杆状结构二种形式的侧面示意图。 半圆形或圆形杆既可以釆用整体成型， 也可 以釆用分体拼接的形式。 其中图 2-18、 2-19是轮缘上有齿的圆形杆或半圆形杆， 它们需要与链条配合使用。 在半圆形杆的半圆形轮缘的凹槽中装有钢丝绳， 如 图 2-6、 图 2-7所示。 半圆形杆比圆形杆节省材料， 并且容易与杆上部固定在一起 。 在合适的位置上， 圆形杆与半圆形杆可以相互替换， 如图 2-15和图 234所示， 各圆形杆、 半圆形杆之间连线方式有多种， 比较经济实用的环绕路径和连接位 置如下： 支杆 41-1、 41-2轮缘凹槽之间由钢丝绳或链条 18连接， 钢丝绳或链条 18 两端固定在轮缘凹槽上， 用画在绳子上的小圆圏表示固定点的位置， 方式如图 2- 9、 291、 292、 293和图 2-15所示的相应环绕路径和位置。 半圆形杆 41-3、 41-4轮 缘凹槽之间由钢丝绳或链条 19连接， 用画在绳子上的小圆圏表示固定点的位置 ， 如图 2-10、 211、 212、 213和图 2-15所示。 半圆形杆 41-2、 41-3轮缘凹槽之间由 钢丝绳或链条 20连接， 用画在绳子上的小圆圏表示固定点的位置， 如图 2- 12、 266、 267、 268和图 2-15所示四种中的任一种。 当完全釆用以上措施连接后 ， 可完全取代类型 1中链轮 42和链条 44在本设备中的作用。 以上钢丝绳或链条 18 ， 19， 20三处位置的连接中每一处位置的连接都可以作为机构的一部分独立使 用， 比如只有单个工作平台工作吋如图 244、 图 245所示； 也可以与其他位置的 连接组合使用， 比如两个工作平台协同工作吋。
[22] 选用类型 2式样的从动及助动机构， 还有一个好处是降低了设备对杆状结构材 料的力学强度要求， 减少了杆状结构受力所需的自身横截面积， 从而节省材料 ， 节约成本， 还可以省去支杆斜撑。 缺点是比类型 1结构复杂。 本文为简化构图 ， 简要介绍原理， 仅在图 1 (从助及助动类型 1与类型 2混合使用） 和图 2-15 (从 动与助动类型 2独自使用） 中画有该机构部件， 其他图中相应位置亦可装配装此 机构。
[23] 类型 1和类型 2中有一种合并杆的变化方式， 即将两个工作平台相邻的两根杆状 结构用一种更长些的杆状结构来代替， 这种杆状结构的中部有孔， 用来安装轴 承， 两端分别与两个工作平台铰接。 如图 2-26、 2-27、 2-28、 2-29和图 233所示。 这种构件减少了平台所需的杆状结构数量， 但是对杆状结构自身材料强度和结 构强度要求高。 工作状态如图 233和图 333所示。
[24] (5)电气控制装置： 包括芯片、 继电器、 控制开关、 可调电阻、 变压器、 行程开 关程等组成的数字电路集中控制箱 5。 控制开关可以控制电机正转、 反转、 停止 ； 行程开关、 继电器控制工作平台在设定位置停止。
[25] (6)可选择安装的自动识障监测装置： 包括设在在上、 下工作平台的前后端装有 无线发射、 接收装置 6， 如图 7所示。
[26] 在设定的反射距离内， 如 1.5米以内发现障碍物， 则发出停止运行信号， 设备停 止运行。 可避免设备运行中工作平台不会与周边障碍物或人相碰。
[27] (7)本设备的框架底座四角上可选择安装轮子 7， 使之具备移动性。 当装配汽车 底盘并配有动力后可向汽车一样自由移动到任意地点， 实现设备资源的合理调 配， 如图 8所示。 在四个立柱的内部可选择安装尖桩 8， 用于松软地基 （如室外 沙土地） 上的固定， 如图 8所示。
[28] (8)可选择安装的阻档装置 9: 防止停放在工作平台上的物体滑下。 阻档装置也 可以单独使用于停车场地面上， 作为车位锁之用。 它包括侧面特定位置开孔眼 9 1的内卷边角钢 92， 截面形状近似于门字型， 方管 93， 头部有锁孔 94及尾部有插 管的弹簧按键 95， 有轮 96的轴 97， 有转轴的护边 98，提拉手柄 99， 如图 9-1及图 9-2 所示。
[29] 使用吋， 通过手柄将水平放置的车位锁向上提起， 嵌在内卷边角钢里的弹簧按 键 95遇到孔眼 91的位置吋， 自动弹出并锁住， 呈三角支撑状态， 如图 9-3和图 9-4 所示； 将车位锁打开吋， 用手指将弹簧按键压下， 阻档装置在自身重力作用下 ， 自动滑下， 呈水平位置， 可供物体穿行，如图 9-2所示。
[30] (9)可选择安装的接触后急停装置 10: 在每个工作平台装有自动识障监测装置的 对面一侧装有碰撞后急停装置， 它有两种设计方案
[31] 第一种方案： 在工作平台这一侧的两个角上安装有两个金属管 10-3， 如图 10所 示， 金属管的顶端装有按压式紧急停止开关 10-1， 在两个金属管之间连接一条拉 绳 10-2， 拉绳 10-2是另一急停开关的启动拉绳。 当工作平台的这一侧运行中碰到 障碍物吋， 障碍物与这一侧的急停按压式开关发生挤压， 或与拉绳发生挤压， 则设备紧急停止。

具体实施方式
[57] 下面结合附图和实施例对本发明进一步说明。 框架类型选用顶部带滑轮的四立 柱型框架， 重物以装载汽车为例。 因选择杆状结构的类型不同， 驱动方式有所 差异， 表现在钢丝绳或链条 34的连接位置不同。 现分二种情况介绍：
[58] 类型 1 : 选择图 2-1、 2-2、 2-3所示的直角形的杆吋， 钢丝绳或链条 34固定在工 作平台上， 如图 5所示， 34可以选用钢丝绳或链条， 也可以选用绳索或传动带。 以下为简化叙述， 将 34统一以钢丝绳为例介绍。 在工作平台 22上存车并将车位 上升到上层空间吋， 停车设备在图 5状态下， 启动运行开关， 减速电机 31正转， 通过传动带 32带动卷筒 33及钢丝绳 34运动， 与固定在工作平台 22上的钢丝绳 34-1 收紧， 与另一工作平台 21连接的钢丝绳 34-2则放松。 在钢丝绳 34-1的拉动下， 工 作平台 22主动上升， 带动与之铰接的从动及助动机构 (包括 4根杆状结构 41、 4个 链轮 42及链条 43)转动。 这 4个链轮的转动借助链条传动又带动与另一工作平台 21 铰接的另外 4个链轮及杆状结构转动， 从而带动另一工作平台 21做相应地下降运 动， 两个工作平台由于通过链条及链轮传递动力， 既可保证协调同步运动， 又 可节约电动机动力输出。 即工作平台 22上升到预定位置后， 另一工作平台 21必 然同吋到达下降位置。 当工作平台 22接近上升预定位置吋， 触及行程开关， 设 备停止， 如图 5所示。
[59] 在取车吋， 通过控制开关使减速电机反转， 带动卷筒及钢丝绳反转， 钢丝绳 34 -1放松， 工作平台 22下降； 与另一工作平台 21铰接的钢丝绳 34-2则收紧， 带动另 一工作平台 21主动上升， 通过链轮、 链条的传动， 相应地使载车板 22由高位下 降到地面， 完成取车过程。
[60] 在工作平台 21上装载汽车上升 /下降的过程与工作平台 22存取车运动方式相反 [61] 类型 2: 当选择半圆形杆或圆形杆， 钢丝绳或链条或传动带 34通过轮缘绳槽端 部固定在半圆形杆或圆形杆上的特定位置， 如图 6和图 234所示； 钢丝绳或链条 或传动带 34也可以固定在工作平台上的特定位置， 如图 1所示。 在工作平台 22上 存车并将车位上升到上层空间吋， 停车设备在图 6状态下， 启动运行开关， 减速 电机 31正转， 通过传动带 32带动卷筒 33及钢丝绳或链条 34运动， 固定在半圆形 杆轮缘凹槽上的钢丝绳或链条 34-1收紧， 与另一工作平台 21铰接的半圆形杆轮缘 上的钢丝绳或链条 34-2则放松。 在钢丝绳或链条 34-1的拉动下， 杆状结构 41绕轴 转动， 带动工作平台 22主动上升， 还带动与之铰接的 4根杆状结构 41转动。 这 4 个杆状结构的转动借助轮缘凹槽上的钢丝绳或链条 18、 19、 20传动又带动与另 一工作平台 21铰接的另外 4个杆状结构转动， 从而带动另一工作平台 21做相应地 下降运动， 两个工作平台由于通过钢丝绳或链条 18、 19、 20相互传递动力， 既 可保证协调同步运动， 又可节约电动机动力输出。 即工作平台 22上升到预定位 置后， 另一工作平台 21必然同吋到达下降位置。 当工作平台 22接近上升预定位 置吋， 触及行程开关， 设备停止， 如图 6所示。
[62] 在取车吋， 通过控制开关使减速电机反转， 带动卷筒及钢丝绳反转， 环绕在半 圆形支杆轮缘凹槽上的钢丝绳或链条放松， 工作平台 22下降； 与另一工作平台 铰接的半圆形支杆轮缘绳槽中的钢丝绳或链条 34-2则收紧， 带动另一工作平台 21 主动上升， 通过钢丝绳或链条 18、 19、 20的传动， 相应地使载车板 22由高位下 降到地面， 完成取车过程。
[63] 在工作平台 21上存、 取车的过程与工作平台 22存取车运动方式相反。
[64] 当设备选用两中立柱框架吋， 驱动机构和从动助动机构的布置位置与以上方式 有所不同， 而工作运动方式基本相同。 具体表现在牵引钢丝绳或链条 34-1、 43-2 分别连在圆形支杆 41-2和 41-3上， 如图 11所示。 其中 34-1—端连接在圆形支杆 41- 2上， 另一端绕过一根中立柱 121上的一个定滑轮向下与卷筒或收链装置相连 （ 中立柱 121上有 2个并排的定滑轮） 。 34-2—端连接在圆形支杆 41-3上， 另一端绕 过中立柱 121上另一个定滑轮向下与卷筒或收链装置相连。 也可以将 34-1、 34-2 连结在圆形支杆 41-1， 41-4上， 只是钢丝绳或链条要长些， 如图 12所示。 [65] 用一种更长些的杆状结构来代替两个工作平台相邻的杆状结构， 即合并杆的情 况下钢丝绳 34-1、 34-2的一端分别反向绕过中立柱 121上的一个定滑轮向下， 再 绕过一个变向滑轮与卷筒连接， 另一端固定在工作平台或圆形杆或半圆形杆上 的特定位置， 如图 333所示。
[66] 选用中立柱框架的本设备， 其工作运动方式与选用四立柱框架吋一致。
[67] 为提高起重能力， 可以釆取多组平台并列同步起重举升的方式， 如图 13-2所示 ， 例如在桥梁建设中将多组平台并列， 可以增加桥面宽度， 提高桥梁的承重能 力。
[68] 此外在上、 下工作平台转换运动过程中， 在上、 下工作平台的前后端装有无线 发射、 接收装置， 如图 7所示。 在人为设定的反射距离内， 如 1.5米以内发现障碍 物， 则发出停止信号， 设备停止运行， 可避免设备运行中工作平台不会与周边 运动的或静止的障碍物或人相碰。
[69] 阻档装置使用吋， 通过手柄将水平放置的车位锁向上提起， 嵌在内卷边角钢里 的弹簧按键 95遇到孔眼 91的位置吋， 自动弹出并锁住， 如图 9-3和图 9-4所示； 将 阻档装置打开吋， 用手指将弹簧按键压下， 阻档装置在重力作用下， 自动滑下 ， 呈水平位置， 如图 9-2所示。
[70] 本设备的框架底座四角上可选择安装轮子 7， 当配有汽车底盘后可自主移动到 任意地点， 或由卡车拖到任意地点， 实现设备资源的合理调配， 如图 8所示； 在 四个立柱的内部可选择安装尖桩 8， 用于松软地基 (如室外沙土地)上的固定。 如 图 1和图 8所示。 对于标准的硬化地面只须用地脚螺钉将底座与地面紧固连接。
[71] 最后， 接触后急停装置 10保障当工作平台的一侧运行中碰到障碍物吋， 障碍物 与这一侧的接触后急停装置接触后， 则设备紧急停止。
[72] 本设备可以起降多种重物， 在合适的条件下可以替代装载举升机、 起重机的某 些功能。 并且操纵单台或多台设备可以快速组成桥梁， 供车辆、 行人通行， 而 且提供上下二层通道， 这在某些紧急情况或自然灾害发生吋是非常有用的。 下 面具体介绍本设备作为桥梁组装结构的用途：
[73] 操纵单台或多台本设备， 使每台设备的工作平台处于同一水平位置或接近同一 水平位置 （允许平台之间存在一定的高度差） 并首尾连接每台设备， 两端配以 斜坡， 可以快速构建桥梁， 当然也可以与现有的已知桥梁结构混合排列组成桥 梁， 如图 13和图 13-1所示。 每台设备的两个平台之间或者多台设备的平台之间不 需要处于绝对的同一水平面， 允许有一定的高度差， 如图 13所示， 这样可以制 造适当的坡度， 可以在接缝处铺设橡胶垫层和斜坡， 以减少路面的颠簸。 其中 平台与平台之间对接， 即桥面结构与桥面结构之间的对接很方便， 无须很严格 。 因为传统方式的组装和对接桥梁， 桥面结构对接处的下方常常靠柱子来支撑 ， 各段桥梁的重量都集中在这些立柱上， 并且需要架桥机或起重机精确吊装到 位； 而本设备的多个平台组成的桥梁结构在平台连接处可以不设立柱支撑， 这 样大大降低架桥难度， 节省了建桥吋间。 原因在于整个结构的受力由钢丝绳或 链条 34以及铰接在横梁上的杆状结构、 立柱来支撑， 并且借助从动与助动机构 可以调节单台设备两个工作平台之间受力平衡。 当然增加桥面连接处的立柱支 撑可以更好地提高整体桥梁结构的受力状况。
[74] 还可以根据地形的高低起伏变化， 设计不同高度的工作平台和立柱， 如图 13所 示。
[75] 釆取多组平台并列同步起重举升的方式， 如图 13-2所示， 例如在桥梁建设中将 多组平台并列， 可以增加桥面宽度， 提高桥梁的承重能力。
[76] 另外， 根据工作平台实际载重量的增加， 可以参照建筑工程中斜拉索桥或悬索 桥拉索的布置方式增加工作平台与立柱之间钢丝绳或链条的连接数量， 增加杆 状结构的数量， 必要的吋候再增加两立柱之间连接横梁 24， 如图 14所示。 根据 工作平台实际载重量大小， 杆或杆状结构也可以釆用建筑工程或机械工程当中 的多种受力结构形式， 例如加强筋， 桁架结构。 图 14中阴影部分表示为下层通 道路面平坦设置的填充物和铺垫层。
[77] 工作平台的形状可以根据实际需要， 制成有凸凹状的非水平面的平台， 这样的 工作平台在某些方面有特别的用处， 比如对架桥很有帮助， 如图 15所示， 其中 2 5指斜坡及伸缩缝装置。
[78] 当需要拆除架设的桥梁， 可以操纵各台设备自动"收缩"成上下两层平台， 然后 由施工方将各台设备拖走； 若其中某段架桥平台发生故障或破损， 可以另外由 新的设备来替换该段设备， 或者操纵设备把发生故障或破损的某段架桥平台降 低高度， 在低高度或接近地面、 海平面处进行维修替换。 这种方法降低了维修 难度， 节省了维修吋间。
[79] 需要指出的是为适应某些场合下的起重需要， 平台可简化为横梁， 如图 225、 2 26； 甚至直接用杆状结构配有的挂钩或吊环来起重， 如图 227、 228所示， 当起 重集装箱吋， 设备的杆状结构可以直接落在集装箱两侧， 此吋平台简化为横梁 ， 再通过横梁配有的夹具索具可以与集装箱的顶角件或底角件用销连接； 或者 直接用网状物兜住载重物体底部， 网状物再与两根横梁挂接。 图 225中釆用的是 沿集装箱长度方向吊装， 也可以沿集装箱宽度方向吊装， 如图 226、 229。
[80] 如果对被举升的重物移动的水平稳定性要求不高， 即允许移动中货物来回摆动 ， 则可以使用一根或两根并列的杆状结构做为起升机构来举升重物， 此吋工作 平台被简化为吊钩、 吊环、 或专用的夹具和索具。 如图 228、 229所示。 在图 229 中釆用一根杆状结构， 工作平台简化为专用的集装箱夹具， 并可以将集装箱进 行竖直面上接近 360度的旋转作业； 图 230中釆用并列的两根杆状结构， 工作平 台简化为专用的集装箱夹具， 并可以将集装箱进行竖直面上接近 360度的旋转作 业。
[81] 以上描述只是本专利一些特定的实施例， 本专利并不仅仅局限于以上图示或描 述的特定结构， 权利要求将覆盖本专利的实质精神及范围内的所有变化方案。
