为使本公开实施例的目的、技术方案和优点更加清楚，下面将对 本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1至图8所示，本公开提供了一种钢箱梁提运架***，钢箱梁提运架***包括运梁轨道1、牵引机构2、浮吊机构3以及吊梁机构4；运梁轨道1设于水面5的岸侧51上，此处的岸侧51也可以指的是湖泊或者江河等的河滩处；且运梁轨道1沿岸侧51的坡面的方向延伸至岸侧51上设置的第一桥墩52处；牵引机构2位于运梁轨道1上且靠近第一桥墩52设置；浮吊机构3漂浮在水面5上，用于将钢箱梁6吊送至运梁轨道1靠近水面5的一端，以使得钢箱梁5在牵引机构2的牵引下沿运梁轨道1移动至预设吊起位置；吊梁机构4位于水面5上方且与预设吊起位置相对应，用于将运送至吊梁机构4下方的钢箱梁6吊起并进行架设。本公开的钢箱梁提运架***，可以通过在水面5的岸侧51上设置运梁轨道1，从而通过浮吊机构3将钢箱梁6吊送至运梁轨道1靠近水面5的一端后，再通过运梁轨道1上设置的牵引机构2将钢箱梁6沿着运梁轨道1牵引至预设吊起位置，运梁轨道1远离水面5的一端设置有用于对钢箱梁6进行阻挡的挡块11，运梁轨道11的底部具有混凝土基础12用于对运梁轨道1进行支撑；且运梁轨道自水面5朝向第一桥墩52延伸，从而可以使得钢箱梁6能够被运送至第一桥墩52处从而便于后续架设在山侧陡坡8的上方的0#桥墩(即第二桥墩53)与1#桥墩(即第一桥墩52)之间。
具体的，如图1所示，运梁轨道1设于水面5的岸侧51上，且沿岸侧51的坡面的方向延伸至岸侧51上设置的第一桥墩52处。由于运输钢箱梁6的船舶在枯水期或者丰水期的时候均可能发生无法靠近岸边的坡面上设置的第一桥墩52处的情况，此时需要通过运梁轨道1将钢箱梁6运输到第一桥墩52处或者第一桥墩52附近以便进行后续架设操作。因此，本实施例中，设置运梁轨道1沿着岸侧51延伸至第一桥墩52处，使得运梁船舶可以靠近运梁轨道1远离第一桥墩52的一侧以将钢箱梁6放置在运梁轨道1上后沿着运梁轨道1运输至第一桥 墩52处或者第一桥墩52附近的任意预设吊起位置，此处的预设吊起位置指的是其在水面5上方的预设架设位置，比如说，钢箱梁6需要被架设在某一位置，此时某一位置处附近可以设置吊梁机构4，从而将某一位置正下方的钢箱梁6吊起进行架设。
如图2所示，牵引机构2位于运梁轨道1上且靠近第一桥墩52设置，使得浮吊机构3将钢箱梁6吊送至运梁轨道1靠近水面5的一端，以使得钢箱梁6在牵引机构2的牵引下沿运梁轨道1移动至预设吊起位置从而进行后续架设。
如图8所示，支架7上方设置有横支撑73，横支撑73上设置有纵梁74，纵梁74上形成有移动轨道75，以供吊梁机构4移动。
如图1至图2所示，本实施例中的架设桥梁以0#桥墩(即第二桥墩53)至1#桥墩(即第一桥墩52)，1#桥墩至2#桥墩之间的钢箱梁的架设为例进行具体介绍：如图1所示，0#桥墩至1#桥墩位于岸侧51的坡面的陡坡8上，1#桥墩至2#桥墩位于岸滩区，由于水面蓄水影响，使得水面的施工区域的最低水位为143.3m，最高水位为173.3m，使得即便在丰水期运输船舶也无法靠近1#桥墩。为了使得在最低水位时也能够进行0#桥墩至1#桥墩、1#桥墩至2#桥墩的钢箱梁的吊装施工，又不需要引入超大型浮吊和搭设超长高大支架，本实施例中，可以采用斜坡状的运梁轨道1进行钢箱梁6运输，然后采用桥面设置的吊梁机构4吊起钢箱梁6进行架设。具体的，运梁轨道1采用两个2m宽的条形混凝土扩大基础，条形基础上方设置双轨道及楔形运梁车作为运梁车21，运梁车21通过牵引机构2的牵引可以在运梁轨道上1移动。运梁车21的长度应大于钢箱梁6的长度，并且楔形的运梁车21的楔形角度与运梁轨道1的最大坡度相同，在运梁车21放在运梁轨道1上后设置有防滑落挡块，用于防止上坡过程中滑落。
示例性的，本实施例中，牵引机构2具体可以为卷扬机22，卷扬机22包括两个，两个卷扬机22沿垂直于运梁轨道1的长度延伸方向间隔设置，且两个卷扬机22分别与运梁车21的两侧连接且两个卷扬机22的行程同步，以使得运梁车21的两侧可以在两个卷扬机22的共同牵引作用下平衡地移动，以防止单侧侧翻。对于卷扬机22的型号选 取，具体可以以最重的钢箱梁6在运梁轨道1上的最陡处上以静摩擦力启动为计算依据，计算牵引力要保留三倍以上的富余系数，卷扬机22的钢丝绳和行走轮组的选取要符合相应的吊装规范要求。另外，卷扬机22采用打入工钢锚的方法进行固定，在卷扬机22的四周挖掘锚根，各打入一根三米长的工20型钢并浇筑混凝土。每台卷扬机22根据底层特点计算的锚固安全系数大于5。
如图1、图2所示，0#桥墩至1#桥墩位于山侧陡坡8，需存梁八片(具体参照图1)，由于钢箱梁6无法运输至0#桥墩至1#桥墩之间，只能依靠吊梁机构4跨越1#桥墩存放至1#桥墩上方搭设的存梁平台71上。因此，吊梁机构4包括吊梁组件41以及设于吊梁组件41底部的行走轮42，吊梁组件41可以包括吊梁桁架41以及吊具412。吊梁组件41用于吊取钢箱梁6进行架设且可通过行走轮42移动至与预设吊起位置相对应的位置，以使得吊梁组件41可以将钢箱梁6吊起高于1#桥墩的顶部，通过吊梁组件41的变幅机构，将钢箱梁6跨过1#桥墩的顶部，放置在0#桥墩至1#桥墩之间的存梁平台71上，然后通过滑动放置在预设位置。
如图2所示，浮吊机构3包括漂浮在水面上的浮座32以及设于浮座32上的浮吊组件31和配重装置33，浮吊组件31包括浮吊桁架311以及吊钩312，浮吊组件31用于吊取钢箱梁6至运梁轨道1上且可相对于浮座32旋转，进而使得浮吊组件31可以吊起钢箱梁6后转动至运梁轨道1的上方以将钢箱梁6放置在运梁轨道1上的运梁车21上，使得卷扬机22牵引运梁车21沿着运梁轨道1移动至第一桥墩52处，使得第一桥墩52上方的吊梁机构4吊起钢箱梁6并跨过1#桥墩的顶部放置在0#桥墩和1#桥墩之间的存梁平台71上，然后将该存放的钢箱梁6依次架设好完成0#桥墩至1#桥墩的钢箱梁6的架设。此外，1#桥墩的左侧设置有支架7，支架7和第一桥墩52的上方设置存梁平台71，且存量平台71横跨于0#桥墩和1#桥墩之间。
参照图1所示，0#桥墩至1#桥墩之间需八片钢箱梁6，即如图1所示的编号为O至编号为V的钢箱梁6，因此可以重复上述过程八次以吊起存放八片钢箱梁以便架设在0#桥墩和1#桥墩之间架设钢箱梁6， 架设好后可以通过斜拉索9固定。
如图9所示，本公开还提供一种运梁架梁方法，包括如下步骤：
S101：将运梁轨道铺设在水面的岸侧的坡面上；其中，运梁轨道沿岸侧的延伸方向延伸至岸侧上设置的第一桥墩处；
S102：将钢箱梁通过浮吊机构运送至运梁轨道上；
S103：将运梁轨道上的钢箱梁通过牵引机构牵引至预设吊起位置；
S104：将牵引至预设吊起位置处的钢箱梁通过吊梁机构吊起并进行拼装；
S105：将拼装好的钢箱梁通过斜拉索焊接固定以完成架设。
具体的，对于运梁轨道的施工，为了减少工程量，在保证运梁轨道的基础混凝土的最小厚度不小于2m的前提下，依照水面的水位涨落区的坡度(也就是岸侧的坡度)设置运梁轨道的坡度。水位退落后，先测量岸侧河滩的高程，采用低埋高挖的原则选择合理的综合坡度，变坡点不宜过多。运梁轨道的地基开挖后，要现场实测地基承载力，最小承载力要求不低于150Kpa。如果承载力过小，可以采用换填、挤淤或者打入松木桩的方法施工。运梁轨道在浇筑前，立模标高由策略放样检测合格后固定，并根据放样标高拉线预埋轨道钢板，在边坡点处两侧不同坡度的基础内预埋一块轨道固定预埋板，以固定断开的轨道端部。运梁轨道安装前由测量放样，在同一横截面内每间隔5m放出轨道中心线，并在变坡点横断面进行加密放样。运梁轨道安装时不仅要保证单根轨道的顺直，而且要保证四根轨道两两间距偏差不超过5mm，高程差小于3mm。
进一步的，在将运梁轨道铺设在岸侧上的步骤之前，运梁架梁方法还包括：在桥墩远离水面的一侧设置支架，并在支架和桥墩之间架设存梁平台，用于存放吊梁机构吊起的钢箱梁。
进一步的，将预设吊起位置处的钢箱梁通过吊梁机构吊起至桥墩上方并进行架设的步骤包括：将多个钢箱梁依次吊起至桥墩上方的存梁平台上；通过吊梁机构吊起钢箱梁并沿存梁平台移动至预设架设位置分别进行架设。
进一步的，在将运送至预设吊起位置处的钢箱梁通过吊梁机构吊 起进行架设的步骤之后，运梁架梁方法还包括：将钢箱梁和与钢箱梁相邻的其他架设好的钢箱梁连接。
进一步的，在将钢箱梁和与钢箱梁相邻的其他架设好的钢箱梁连接的步骤之后，运梁架梁方法还包括：将钢箱梁通过斜拉索固定。
如图3至图7所示，1#桥墩(即上述实施例所指的第一桥墩52)至2#桥墩之间需要架设9片钢箱梁，即如图1中所示的编号D至编号N的钢箱梁。具体的整个钢箱梁(编号为H-编号为V的共计15片的钢箱梁)的架设过程为：
流程一：如图3、图4所示，先将运梁轨道和1#桥墩左侧的支架搭设完成，然后采用浮吊机构将编号为I-编号为L的钢箱梁吊起至运梁车上，运梁车在牵引机构的牵引下运至桥面的吊梁机构的正下方，吊梁机构将钢箱梁缓缓吊起，然后再将钢箱梁依次架设好连接在一起并通过斜拉索固定。
流程二：如图5所示，采用浮吊机构依次将编号为V-编号为O的钢箱梁吊起至运梁车上，运梁车在牵引机构的牵引下运至运梁轨道的顶端，即1#桥墩处，此时桥面上的吊梁机构依次吊装编号为V-编号为O的钢箱梁至1#桥墩的顶部，并在支架上移动就位后进行架设。
流程三：如图6所示，桥面上的吊梁机构吊装编号为N的钢箱梁至1#桥墩的顶部，并进行预偏。
流程四：如图7所示，吊梁机构具有变幅机构，可以吊装编号为M的钢箱梁进行架设，然后牵引编号为N的钢箱梁进行合拢施工。
流程五：如图7所示，桥面的吊梁机构进行后续的安装施工，并且进行合拢施工。
