吊车吊钩偏角激光动态显示设置
[0001] 技术领域吊车吊钩偏角激光动态显示设置(本设置,下同),属于起重机吊装监控 技术领域,确切地说它是监控吊车垂直吊装的一种设置。
[0002] 背景技术吊车稳定性差要求垂直吊装,由于自身缺失垂直吊装的显示、监视设置, 故吊车司机无法判断重物抬吊或二独立吊点同时受力时(不仅是抬吊,还有单机滑移法、 单机旋转法吊装重物等),其吊钩是否处于垂直状态,而要由吊装指挥者,依据监视被吊重 物垂直吊装者提供的信息指挥司机操控,既不及时又不准确…
[0003] 发明内容鉴于吊车自身缺失垂直吊装的显示设置,申请人曾先后提出: 200910112531. 9起重机垂直吊装激光监视装置 [P]和 201110134401. 2吊车吊钩偏角激光 显示与监视设置 [P]专利申请,现前者已于 2011年 10月 5日发布授权公告。 由于控制吊 车垂直吊装的核心是控制吊车吊钩偏角,本设置即实现对吊车吊钩偏角的方向、大小进行 动态显示,并为控制消除吊钩偏角提供依据。
[0004] 吊车吊钩偏角激光显示器的作法:一种是在吊装中同吊车吊钩产生相同偏角的滑 轮组构件上,装设有平面的激光反光体与经球绞连接后的激光发生器,并将激光反光体平 面装设于激光发生器的正前方,且满足当吊钩偏角 0β 时反光体平面为水平面;在反光体 平面上以吊钩偏角 0° 时,激光发生器发射于水平面上的光点为座标原点(称原点,下同), 标示出前后与左右的十字坐标,同时以原点为园心,分别各按以吊钩产生不同偏角时,激光 发生器发射于平面上的光点至原点间距为半径,作出与产生偏角一" ^对应的同心园 ,每一 同心园对应标出一个偏角度数,原点标 0° ,原点应作出腥目的标示。
Ε0005] 另一种是在吊装中同吊车吊钩产生相同偏角的滑轮组构件上,装设有凹向球面的 激光反光体与经球绞连接后的激光发生器,并将激光反光体凹向球面(以球绞中心为园 心,以球绞至反光体为半径的凹向球面)装设于激光发生器的芷前方,在凹向球面上以吊 钩偏角 0 时,激光发生器发射于凹向球面上的光点为座标原点(称原点,下同),标示出前 后与左右的十字坐标,同时以原点为园心,分别各¾以吊钩产生不同偏角时,激光发生器发 射于凹向球面上的光点至原点间距为半径,作出与产生偏角一一对应的同心园,每一同心 园对应标出一个偏角度数,原点标 0。 ,原点应作出腥目的标示:
[0006] 由于激光发生器在自重(重量不足时加配重)和球绞自动调整下,激光发生器始 终发射铅垂方位的激光,且激光发生器球绞与激光反光体相对位置不变,因而激光发生器 发射于凹向球面或平面上的光点至廪点间距,与吊钩产生的偏角数值一一对应,故可依激 光发生器发射至凹向球面或平面上的光点,于所处标出对应偏角数值的同心园位置,动态 显示出吊钩的偏角的方向和偏角度数。
[0007] 为了在各监控点(包括本吊车司机操作室与吊装指挥现场,以及抬吊时互为协同 方的协同吊装司机操作室)显示吊钩的偏角,设置了吊车吊钩偏角激光监视装置。其作法: 一种是先装设吊车吊钩偏角激光平面显示器;同时在吊车吊钩偏角激光平面显示器的反光 体平面下方装设无线攝象头;在监控点装设与无线攝象头配套的无线接收机、控制显示器, 将吊装中在吊车吊钩偏角激光平面显示器的反光体平面上图象放大后,于监控点的屏幕上 动态显示吊钩偏角的方向和偏角度数。 替换页 (细则第 26条) [0008] 另一种是先装设吊车吊钩偏角激光凹面显示器;同时在吊车吊钩偏角激光凹面显 示器的反光体凹向球面下方装设无线攝象头;在监控点装设与无线攝象头配套的无线接收 机、控制显示器,将吊装中在吊车吊钩偏角激光凹面显示器的反光体凹向球面上图象,放大 后于监控点的屏幕上动态显示吊钩偏角的方向和偏角度数;
[00093 本设置首次提出对吊车吊钩偏角方向和偏角度数进行动态显示的方案,具有新颖 性,又由于实现吊车吊钩偏角的方向和偏角度数进行动态显示,较好克服了吊车不垂直吊 装的风险,开发出既适合于所有单机吊装,也适合于抬吊作业的垂直吊装显示与监视设置, 并为消除吊钩偏角提供了依据,因而具有创造性。 本设置可用于吊车垂直吊装的显示与监 视。 具体实施方式
