Description

收放式楼宇外墙作业平台 技术领域
本发明涉及一种建筑装饰施工装置，特别涉及一种建筑外墙清洗、装饰的一种作业装置。
背景技术
现有技术中，有一种建筑物外墙作业用的无人吊篮系统，其申请号为：CN03145818.1，申请日：20030711，公开(公告)号：CN1570331A，公开(公告)日：20050126；该系统目的是提供一种适用于高层建筑物外墙的无人自动作业用的吊篮系统，能够使现有的吊篮系统变得轻巧简易，使低成本高质量的大厦外墙的无人自动化检查、清洗、图案绘制等工作都成为可能。
为了达到上述的目的，该发明提供了一种建筑物外墙作业用无人吊篮系统，包括：一吊架，设在所述建筑物的顶部，该吊架向外延伸有一悬臂；所述悬臂上设有两滑轮；一地面车，其上装载有卷扬机构及多个配重；一吊篮；及一缆绳，一端与吊篮的底部固定连接，另一端依次穿过所述的卷扬机构、所述的两个滑轮然后固结在该吊篮的顶部，从而形成一条封闭环；所述吊篮包括一头部和一尾部，所述头部设置在该外墙的一侧，所述尾部由该头部向外延伸形成，该尾部设置有一伸缩机构，在该伸缩机构的驱动下，所述吊篮紧贴该外墙沿垂直方向移动。其克服了载人吊篮必须载人因而使吊篮的重量(一般约为700公斤)和安全要求都相对较高因而成本昂贵的缺点，其可以进行大厦外墙的清洗、装饰、绘画等。
其不足之处在于：该装置需要地面牵引车牵引，容易发生意外事故。
发明内容
本发明的目的是提供一种收放式楼宇外墙作业平台，使其能更加安全工作，收纳体积小，能够实现自平衡。
本发明的目的是这样实现的：一种收放式楼宇外墙作业平台，包括基座，基座上设置有卷扬机，所述基座上直立设置有两根立柱，基座上与立柱一一对应设有铰座，所述铰座上可转动地连接有转臂，转臂上设置有第一导轮、第二导轮和第三导轮，转臂下侧设有作业平台，作业平台两侧的框架上设置有第四导轮和第五导轮，所述第一导轮、第三导轮、第五导轮与第四导轮的中心连线呈矩形，第二导轮位于第一导轮和第三导轮之间，立柱上设有上换向轮、下换向轮和锚固件，一钢索的一个端头与锚固件相固定，钢索的另一端依次绕过下换向轮、第二导向轮、第一导向轮、第四导向轮、第五导向轮、第三导向轮及上换向轮后， 再绕装在卷扬机的辊筒上；所述基座侧面设有支撑件，当转臂处于水平位置时，支撑件恰好支撑在转臂下侧。
该装置具有如下几种工作状态，其一，卷扬机将整个装置收起，使得转臂贴靠在立柱上，同时作业平台也被拉紧并贴靠在转臂上，装置整体尺寸很小，方便安装在楼顶。第二，卷扬机将转臂放下，转臂在自重作用下转动，直到转臂支撑在支撑件上，此时，作业平台处于水平位置，装置处于待用状态，人员、工具可以运送到作业平台上。其三，继续松卷扬机，作业平台脱离转臂向下运动，作业平台重心在钢索下侧，在自重作用下可以实现自平衡，不会发生倾覆危险，重心越低、自重越大，平衡性越好，因此，其承载能力大。于现有技术相比，其有益效果在于：该装置收放方便，收起后体积小，结构紧凑，作业平台能够实现自平衡，仅用两个立柱上分别对应设置两根钢索即可实现作业平台的自由收放，其稳定性好。其可以用于大型建筑外墙的清洗、墙面检查、外墙装饰等工作中。
为保证作业平台的平衡，所述转臂下侧设有两个上扶正轮，框架两侧分别设有下扶正轮，所述上扶正轮位于第一导轮、第三导轮下方，下扶正轮分别位于第四导轮、第五导轮上侧，上扶正轮、下扶正轮的轮槽分别卡设在钢索外。上扶正轮和下扶正轮的设置，保证了装置具有较好的抗风性，其使用可靠性提高。进一步地，上扶正轮、下扶正轮的轴线与第一导轮的轴线相垂直。其可以从两个方向上限制钢索，进一步避免钢索跳槽脱出轮槽。
为保证作为平台在自重下能实现自平衡，所述作业平台下侧设有平衡配重。平衡配重可以进一步降低重心，保证作业平台的稳定。
作为本发明的进一步改进在于，所述作业平台两侧设有用于测试水平度的平衡传感器，通过水平传感器控制卷扬机启停动作。
为避免钢索出现跳槽，所述第三导轮侧面设有外限位轮，钢索穿过第三导轮和外限位轮之间。通过外限位轮限制钢索，尤其是在转臂收起和初始放下时，可以具有良好的导向作用，避免钢索跳出轮槽。
为方便人员操作，所述框架上侧设有扶手。
为减少碰撞损坏，所述框架上侧与转臂之间设有下避碰垫。
作为本发明的进一步改进，所述立柱上设有压在钢索上的限位开关，当钢索松脱时，限位开关发出信号停止卷扬机工作。当作业平台中途遇到搁置等危险时，例如作业平台一端挂碰到楼层并搁置在某一平台上时，限位开关动作，使得卷扬机停止工作，以避免进一步的危险发生。
进一步地，所述立柱上设有上避碰垫，当转臂收起时，上避碰垫恰好抵触在转臂上。

具体实施方式
如图所示，为收放式楼宇外墙作业平台15，包括基座22，基座22上设置有卷扬机23，基座22上直立设置有两根立柱1，基座22上与立柱1一一对应设有铰座21，所述铰座21上可转动地连接有转臂8，转臂8上设置有第一导轮9、第二导轮10和第三导轮11，转臂8下侧设有作业平台15，作业平台15两侧的框架17上设置有第四导轮18和第五导轮13，所述第一导轮9、第三导轮11、第五导轮13与第四导轮18的中心连线呈矩形，第二导轮10位于第一导轮9和第三导轮11之间，立柱1上设有上换向轮2、下换向轮3和锚固件6，一钢索7的一个端头与锚固件6相固定，钢索7的另一端依次绕过下换向轮3、第二导向轮、第一导向轮、第四导向轮、第五导向轮、第三导向轮及上换向轮2后，再绕装在卷扬机23的辊筒上；所述基座22侧面设有支撑件19，当转臂8处于水平位置时，支撑件19恰好支撑在转臂8下侧，支撑件19可以如图所示支撑在建筑墙体20边缘，作业平台15整体可以移出墙体20外。
转臂8下侧设有两个上扶正轮25，框架17两侧分别设有下扶正轮27，所述上扶正轮25位于第一导轮9、第三导轮11下方，下扶正轮27分别位于第四导轮18、第五导轮13上侧，上扶正轮25、下扶正轮27的轮槽分别卡设在钢索7外。上扶正轮25和下扶正轮27的设置，保证了装置具有较好的抗风性，其使用可靠性提高。进一步地，上扶正轮25、下扶正轮27的轴线与第一导轮9的轴线相垂直。其可以从两个方向上限制钢索7，进一步避免钢索7跳槽脱出轮槽。
为保证作为平台在自重下能实现自平衡，所述作业平台15下侧设有平衡配重14。平衡配重14可以进一步降低重心，保证作业平台15的稳定。
作业平台15两侧设有用于测试水平度的平衡传感器26，通过水平传感器控制卷扬机 23启停动作。当发生偏斜时，卷扬机23停机，避免出现安全事故。
为避免钢索7出现跳槽，所述第三导轮11侧面设有外限位轮12，钢索7穿过第三导轮11和外限位轮12之间。通过外限位轮12限制钢索7，尤其是在转臂8收起和初始放下时，可以具有良好的导向作用，避免钢索7跳出轮槽。
为方便人员操作，所述框架17上侧设有扶手16。
为减少碰撞损坏，所述框架17上侧与转臂8之间设有下避碰垫24。立柱1上设有上避碰垫4，当转臂8收起时，上避碰垫4恰好抵触在转臂8上。
立柱1上设有压在钢索7上的限位开关5，当钢索7松脱时，限位开关5发出信号停止卷扬机23工作。当作业平台15中途遇到搁置等危险时，例如作业平台15一端挂碰到楼层并搁置在某一平台上时，限位开关5动作，使得卷扬机23停止工作，以避免进一步的危险发生。
该装置具有如下几种工作状态，其一，卷扬机23将整个装置收起，使得转臂8贴靠在立柱1上，同时作业平台15也被拉紧并贴靠在转臂8上，装置整体尺寸很小，方便安装在楼顶。第二，卷扬机23将转臂8放下，转臂8在自重作用下转动，直到转臂8支撑在支撑件19上，此时，作业平台15处于水平位置，装置处于待用状态，人员、工具可以运送到作业平台15上。其三，继续松卷扬机23，作业平台15脱离转臂8向下运动，作业平台15重心在钢索7下侧，在自重作用下可以实现自平衡，不会发生倾覆危险，重心越低、自重越大，平衡性越好，因此，其承载能力大。于现有技术相比，其有益效果在于：该装置收放方便，收起后体积小，结构紧凑，作业平台15能够实现自平衡，仅用两个立柱1上分别对应设置两根钢索7即可实现作业平台15的自由收放，其稳定性好。其可以用于大型建筑外墙的清洗、墙面检查、外墙装饰等工作中。
本发明并不局限于上述实施例，在本发明公开的技术方案的基础上，本领域的技术人员根据所公开的技术内容，不需要创造性的劳动就可以对其中的一些技术特征作出一些替换和变形，这些替换和变形均在本发明的保护范围内。
