Description

一种细长型压力连接条装卸方法及其装置 技术领域
本发明属设备装卸方法，尤其是涉及细长型设备装卸的方法。
背景技术
随着我国工业行业的迅猛发展，对工业材料内部质量要求的不断提高，大型拉伸机设备安装工程越来越多。
拉伸机的工作原理是将需拉伸的板材放置在两拉伸头设备上并通过拉伸头上设置的液压钳口夹紧，其中一端拉伸头上设置两件对称布置的主液压缸，另一拉头通过细长压力连接条与主液压缸进行连接，板材拉伸时通过主液压缸动作将拉伸力经拉力连接条传递到另一拉头上，实现两拉头同时向相向方向运动而使固定在两拉头上的板材进行拉伸，改变板材内部质量。
通常拉伸机均布置在高度在20米以内的单层厂房内，而大多数拉伸机布置区域厂房配置的行车吊装吨位满足不了压力连接条的吊装需要，如60MN拉伸机压力连接条形状为长方体，长30000mm,宽700mm,高800mm,单件净重86t。此设备特点是细长杆件，刚性较差，设备安装时为保证安装质量和使用效果，对压力连接条装卸时需做好装卸变形控制措施。因厂房内行车不能直接满足装卸需要，且厂房高度有限，采用单台大型吊车无法在厂房内直接装卸就位，且如装卸受力点少，单台吊车装卸时很容易因设备本身的自重而造成压力连接条变形甚至是损坏，造成经济损失，而且还直接制约着工程的施工进度。
发明内容
本发明所要解决的技术问题是提出一种细长型压力连接条装卸方法及其装置，实现压力连接条的装卸就位，降低经济损失的风险，保证了工程施工的进度。
为实现上述目的，本发明一种细长型压力连接条装卸方法，其步骤是：
第一步：选择吊车型号及站位位置，根据厂房内净空高度及设备基础周围的场地情况，再结合设备就位时吊车作业半径的参数要求，选用了两台300t液压汽车吊，'一'字站位形式设置在压力连接条设备基础的一侧。并根据压力连接条吊装的设置的位置及吊装同步旋转就位时参数的要求，设置两台吊车相对与设备基础的纵向和横向尺寸。
第二步：设置吊装吊具，取Ø273×12的无缝钢管6m长制成吊具,在吊具两端开设以纵向对称且与吊具中心线呈600夹角的长方通口，通口尺寸为302×22mm，将尺寸为长700mm,宽300mm,厚20mm吊耳插入其中吊具由两根吊装绳分别固定在两台吊车吊钩和吊具吊耳上，完成吊装吊具设置工作。
第三步：设备的吊装就位，缓慢同步起升两台吊车的起吊绳，使压力连接条提升所需的高度尺寸，停止提升，然后两台吊臂分别缓慢同步进行顺时针和逆时针旋转，将压力连接条缓慢对抬就位到工作液压缸上，完成压力连接条工作液压缸连接，从而完成设备的吊装就位的工作。以此类推实现第二件压力连接条的吊装工作。
第四步：选择液压轴线车型号及设定各车站位位置，根据厂房内净空高度及设备基础周围的场地情况，再结合设备装卸车时吊车作业半径的参数要求，选用一台30米长液压轴线车，设置在压力连接条设备基础的一侧两台吊车、液压轴线车的站位设置和型号的选择可结合具体的施工现场情况进行调整，以满足相关吊装参数的需要，从而最终实现设备的卸车，其中一台吊车与液压轴线车呈'一'字型站位，且车尾对车尾，两车尾预留一定距离，另一台吊车站位与液压轴线车呈'八'字型站位，且吊车车尾相对液压轴线车车头，形成两台吊车分设于液压轴线车两端，形成对抬设置，并根据压力连接条吊装点的设置位置及吊装同步旋转卸车时参数的要求，设置两台吊车相对与设备卸车位置的纵向和横向尺寸。
第五步：设备的卸车及车辆的撤场，先按照压力连接条需卸车的位置，布置好一台吊车，将需运输的压力连接条通过液压轴线车运输到指定的位置，再将另一台吊车设置在液压轴线车车头的指定角度位置，将四根吊装绳按压力连接条吊装固定的尺寸要求，穿过压力连接条本身自有的通孔，并将穿过压力连接条的吊装绳的绳扣中插入的圆销，使吊装绳一端与压力连接条固定，再分别将吊装绳另一端与吊具吊耳下吊孔连接，使压力连接条在两台吊车和两根吊具及吊装绳共同作用实现两吊车及四点受力对抬状态。缓慢同步起升吊车的起吊绳，使压力连接条提升到所需的高度尺寸，停止提升，然后两台吊车的吊臂分别缓慢同步进行顺时针和逆时针旋转，将压力连接条缓慢对抬放置在拉伸机基础指定的位置，完成压力连接条卸车的工作。以此类推实现第二件压力连接条的卸车工作。
当压力连接条从液压轴线车上卸载后，撤离与液压轴线呈'八'字形设置的吊车后，再撤离液压轴线车和另一台吊车，完成压力连接条的短途运输和卸车工作。
所述第四步与液压轴线车呈'一'字形设置的吊车车尾与液压轴线车车尾距离为300mm。
本发明所提出的用于一种细长型压力连接条装卸方法的装置，包括两台吊车、液压轴线车、吊装绳、吊具、圆销，吊车通过吊装绳与吊具连接，吊具与压力连接条通过吊装绳和圆销连接，处于吊装状态时，两台吊车沿压力连接条对称设置；处于卸车状态时，其中一台吊车与液压轴线车呈'一'字形设置，另一台吊车与液压轴线车呈'八'字形设置。
所述的吊具包括吊耳，吊具两端开设长孔并将吊耳以与吊具呈镜像600插入并与吊具焊接连接。
所述吊耳两端各开有Ø60的通孔且孔两侧均加焊有内外直径分别为Ø200、Ø60厚度为20mm的吊装孔壁加强圆垫板。
本发明所提出的一种细长型压力连接条吊装方法及其装置，在厂房和设备基础特定的条件限制下，利用吊装装置实现设备的吊装就位，减少发生设备变形或损坏的经济风险，降低施工成本投入，保证了工程施工的进度及质量要求。

第二步：设置吊装吊具，取Ø273×12的无缝钢管6m长制成吊具,在吊具两端开设以纵向对称且与吊具中心线呈600夹角的长方通口，通口尺寸为302×22mm，将尺寸为长700mm,宽300mm,厚20mm吊耳插入其中吊具由两根吊装绳分别固定在两台吊车吊钩和吊具吊耳上，完成吊装吊具设置工作；
第三步：设备的吊装就位，缓慢同步起升两台吊车的起吊绳，使压力连接条提升所需的高度尺寸，停止提升，然后两台吊臂分别缓慢同步进行顺时针和逆时针旋转，将压力连接条缓慢对抬就位到工作液压缸上，完成压力连接条工作液压缸连接，从而完成设备的吊装就位的工作。以此类推实现第二件压力连接条的吊装工作；
第四步：选择液压轴线车型号及设定各车站位位置，根据厂房内净空高度及设备基础周围的场地情况，再结合设备装卸车时吊车作业半径的参数要求，选用一台30米长液压轴线车，其中一台吊车与液压轴线车呈'一'字型站位，且车尾对车尾，两车尾预留一定距离，另一台吊车站位与液压轴线车呈'八'字型站位，且吊车车尾相对液压轴线车车头，形成两台吊车分设于液压轴线车两端，形成对抬设置，并根据压力连接条吊装点的设置位置及吊装同步旋转卸车时参数的要求，设置两台吊车相对与设备卸车位置的纵向和横向尺寸；
第五步：设备的卸车及车辆的撤场，先按照压力连接条需卸车的位置，布置好一台吊车，将需运输的压力连接条通过液压轴线车运输到指定的位置，再将另一台吊车设置在液压轴线车车头的指定角度位置，将四根吊装绳按压力连接条吊装固定的尺寸要求，穿过压力连接条本身自有的通孔，并将穿过压力连接条的吊装绳的绳扣中插入的圆销，使吊装绳一端与压力连接条固定，再分别将吊装绳另一端与吊具吊耳下吊孔连接，使压力连接条在两台吊车和两根吊具及吊装绳共同作用实现两吊车及四点受力对抬状态。缓慢同步起升吊车的起吊绳，使压力连接条提升到所需的高度尺寸，停止提升，然后两台吊车的吊臂分别缓慢同步进行顺时针和逆时针旋转，将压力连接条缓慢对抬放置在拉伸机基础指定的位置，完成压力连接条卸车的工作。以此类推实现第二件压力连接条的卸车工作；
当压力连接条从液压轴线车上卸载后，撤离与液压轴线呈'八'字形设置的吊车后，再撤离液压轴线车和另一台吊车，完成压力连接条的短途运输和卸车工作。
2、根据权利要求1所述的一种细长型压力连接条装卸方法，其特征在于第四步与液压轴线车呈'一'字形设置的吊车车尾与液压轴线车车尾距离为300mm。
3、一种用于细长型压力连接条装卸方法的装置，包括两台吊车、液压轴线车、吊装绳、吊具、圆销，其特征在于吊车通过吊装绳与吊具连接，吊具与压力连接条通过吊装绳和圆销连接，处于吊装状态时，两台吊车沿压力连接条对称设置；处于卸车状态时，其中一台吊车与液压轴线车呈'一'字形设置，另一台吊车与液压轴线车呈'八'字形设置。
4、根据权利要求3所述的一种用于细长型压力连接条装卸方法的装置，其特征在于吊具包括吊耳，吊具两端开设长孔并将吊耳以与吊具呈镜像600插入并与吊具焊接连接。
5、根据权利要求3所述的一种用于细长型压力连接条装卸方法的装置，其特征在于吊耳两端各开有Ø60的通孔且孔两侧均加焊有内外直径分别为Ø200、Ø60厚度为20mm的吊装孔壁加强圆垫板。
