  • the invention relates to the technical field of continuous beam casting construction, in particular to a cantilever casting walking all-in-one machine.
  • Cantilever cast-in-place continuous beams are mostly constructed in harsh terrain areas such as across roads, across rivers, and across mountainous areas. They are generally constructed using hanging basket cantilever formwork.

优选的,本实施例提供了一种具体的支撑骨架系统,包括立柱14、下行走梁7、上承重梁15和横联系结构,两根立柱14、一根下行走梁7和一根上承重梁15围成支撑桁架,具体的,立柱14平行竖直设置,上端与上承重梁15连接,下端与下行走梁7连接,上承重梁15部分节段和下行走梁7部分节段与立柱14围成支撑桁架,两片支撑桁架通过横联系结构连接,支撑桁架为方形,该横联系结构可以是连接在立柱14之间、和/或上承重梁15之间,和/或下行走梁7之间,只需要将两个支撑桁架固定成整体即可,由于支撑骨架系统前端吊装钢筋笼受到的压力更大,因此,优选的,在两根上承重梁15的前端上面连接有上前横梁16,在两根位于前侧的立柱14下部前面也连接有下后横梁29,以更好的保证支撑骨架系统前侧的稳定性。为保证支撑骨架系统的稳定性和支撑强度,在立柱14、下行走梁7和上承重梁15围成的支撑桁架中,设置有可拆卸的骨架斜撑8和/或骨架纵梁连接于两根立柱14之间,本实施例图1中所示为一种优选的方式,立柱14的中部之间连接有骨架纵梁,骨架斜撑8连接于立柱14顶端和骨架纵梁的中部之间、以及立柱14底端和骨架纵梁的中部之间。为使钢筋笼18吊装下放时不被支撑骨架系统所遮挡,上承重梁15的中部与位于前侧的立柱14上端连接,即上承重梁15前端伸出位于前侧的立柱14之外,为保证上承重梁15的支撑强度和稳定性,在上承重梁15的前端和位于前侧的立柱14之间也可以连接有可拆卸的骨架斜撑8;为保证整个支撑骨架系统的平衡性,在下行走梁7后端还可以连接有下行走梁延长段,下行走梁延长段和下行走梁7之间可以通过螺栓锚固,即如图3所示的结构,下行走梁延长段与位于后侧的立柱14之间连接有可拆卸的骨架斜撑8。对于支撑骨架系统中的可拆卸连接的方式,均可采用螺栓连接,方便拆装。而更优选的,立柱14选择为可伸缩结构。钢筋笼18预制可以在连续梁梁段上面的固定位置完成,而整个吊装钢筋笼18的装置运行到下一浇筑节段还有一定的距离,在吊装钢筋笼18的装置依靠走行系统整体移动时,降低立柱14高度,降低一体机的重心,如此可提高施工的安全性,而在将钢筋笼18由支撑骨架系统后端吊运至前端时,提升立柱14高度,能保证钢筋笼18顺利通过,不受支撑骨架系统的阻挡。对于立柱14的可伸缩结构,只要能实现立柱可伸缩功能的结构均可,例如可以是两根套管式结构,如包括上立柱节段和下立柱节段,上立柱节段的下端套在下立柱节段的上端外围,并通过螺栓固定,当需要调整立柱的高度时,解除螺栓,将上立柱节段向上或向下移动,移动完成后在用螺栓固定即可,当然也可以采用其他便于伸缩的形式,柱状物体的伸缩结构为现有技术,此处不再详细叙述。当立柱14之间设置有骨架斜撑8时,为适应立柱14的不同高度,骨架斜撑8也设置为可拆卸式,骨架斜撑8与立柱14之间的连接采用螺栓连接,根据立柱的高度,选择合适长度的骨架斜撑8进行替换即可,或者换一种形式,骨架斜撑8也可以采用可伸缩结构。对于本实施例图1和3中所示的骨架斜撑8连接于立柱14顶端和骨架纵梁的中部之间、以及立柱14底端和骨架纵梁的中部之间的结构,且立柱14采用套管式,在调整立柱14高度时,骨架纵梁与上立柱节段连接,因此,骨架纵梁上面的骨架斜撑8长度不需要调整,只需要调整骨架纵梁下面的骨架斜撑8即可。
针对于上述支撑骨架系统,本实施例提供了一种钢筋笼吊运轨道13的具体设置方式,上承重梁15内侧设置有钢筋笼吊运轨道13,本实施例中,上承重梁15采用截面为L型的箱型梁,结合图21和图22所示,两根上承重梁15的L型箱型梁呈横向延伸的底部相对设置,为钢筋笼吊运轨道13提供支撑。如此可充分利用现有的支撑骨架系统。本实施例也提供了一种第一前吊带17和后吊带25与支撑骨架系统的连接结构,第一前吊带17的上端分别与上前横梁16的两端连接,后吊带25的上端分别与上后横梁19的两端连接。
本实施例提供了一种钢筋笼装配系统的一种优选结构,为实现钢筋笼18的旋转,吊具机构至少包括旋转吊具10,旋转的角度不小于90°。钢筋笼18通过旋转吊具10旋转90°,再下放至连续梁模板中,如此可有效缩减支撑骨架系统的宽度,提高施工的安全性。
更进一步的,本实施例提供了一种更便于实现本发明目的吊具机构,结合图3和图4所示,吊具机构包括吊具承重梁45、吊装件11和旋转吊具10,吊重车12至少设置有两个,之间连接有吊具承重梁45,吊具承重梁45下面设置有吊装件11,吊装件11下面悬吊有旋转吊具10,旋转吊具10用于吊装及转动钢筋笼18,钢筋笼吊钩906上端与吊架纵梁903连接。对于吊重车12,在本实施例中,由于钢筋笼18重量较大,钢筋笼吊运轨道13可以设置有2条,每根上承重梁15内侧均设置有一条,吊重车12可以设置有4辆,位于同一轨道上的吊重车12之间连接有吊重车连接纵梁,吊重车连接纵梁通过横向的吊具承重梁45连接为一整体,吊具承重梁45与吊装件11连接,吊装件11能沿着吊具承重梁45横向移动,该结构可采用现有的桁吊吊机,或者类似于龙门吊中的吊装结构,或是采用葫芦吊,且有驱动结构驱动葫芦吊左右移动,作为吊装件11,必然的,还可以完成钢筋笼18下放和提升的功能。更进一步的,旋转吊具10采用电动回转机构。常见的电动回转机构,即通过电机带动蜗杆,蜗杆带动涡轮旋转,进而带动旋转体旋转的机构,电动回转机构为现有技术,此处不再详述。对于钢筋笼18的预制,可以是在工厂预制,可以在施工现场地面预制完成,也可以是在连续梁梁面上集中加工。出于便于运输考虑,当施工1#连续梁节段时,钢筋笼18在施工现场地面预制完成,通过塔吊吊装至支撑骨架系统内或前端,当施工2#连续梁节段及后续节段施工时,在连续梁梁面上集中加工,当一体机通过走行系统行走至已浇筑完成的连续梁节段的前端时,通过平板运输车将钢筋笼18运输至一体机的后端,采用吊装件11将钢筋笼18由支撑骨架系统的后端吊运至前端即可。
为保证吊装过程中钢筋笼不容易发生变形,本实施例对于钢筋笼的吊运,还采用了多点吊架结构9,旋转吊具10下面连接有多点吊架结构9,结合图22-25所示,多点吊架结构9包括吊架横梁904、吊架纵梁903、连接吊耳 909、柔性悬吊单元902、旋转架901和钢筋笼吊钩906,吊架横梁904至少设置有两根,且通过多根吊架纵梁903连接,吊架横梁904上面设置有连接吊耳909,连接吊耳909相对吊架横梁904的纵向中心线至少对称设置有4个,且通过柔性悬吊单元902与旋转架901连接,旋转架901与旋转吊具10连接,钢筋笼吊钩906上端与吊架纵梁903连接,下端用于钩住钢筋笼18。旋转吊具10旋转,带动旋转架901旋转,旋转架901再带动吊架横梁904和吊架纵梁903旋转,进而带动钢筋笼18旋转。本实施例所示的连接吊耳909有14个,每根吊架横梁904连接有7个,其中,在吊架横梁904的中间有1个,相对吊架横梁904的纵向中心线,每侧设置有3个,呈对称设置,其中同一侧边的3个连接吊耳909通过钢链或钢筋各自连接于旋转架901对应一侧边的一端,中间的1个连接吊耳909通过钢链或钢筋连接于旋转架901对应一侧边的中间,钢链或钢筋即为柔性悬吊单元902。通过多点吊架结构9,可以避免吊装过程中出现钢筋笼18变型的问题,同时也解决吊装过程中钢筋笼18吊装受力不均匀的问题。
进一步的,走行系统包括滚动轮组结构6,滚动轮组结构6可采用多种形式,如可直接采用多个滚动轮,能实现一体机的移动即可。但为降低整个一体机的高度,本实施例还提供了一种优选的结构,结合图5-7所示,滚动轮组结构6包括走行驱动电机601、变速器602、主动轮603、从动轮604和围护钢架606,走行驱动电机601设置在围护钢架606上面,围护钢架606为走行驱动电机601提供支撑,走行驱动电机601为变速器602转动提供动力,变速器602通过传动件带动主动轮603转动,主动轮603通过传动件带动从动轮604转动,传动件可采用皮带或链轮,根据实际情况选择,变速器602可以选择是比主动轮603半径小的齿轮或链轮结构,从而实现变速功能。主动轮603和从动轮604半径相同,设置于围护钢架606内,并通过轴承与围护钢架606连接,围护钢架606可设置为方形,与走行轨道机构保持一定的间隙,其能为主动轮603和从动轮604提供保护,同时为与主动轮603和从动轮604的转轴连接的轴承提供支撑力,主动轮603和从动轮604能匹配行走于走行轨道机构上面,围护钢架606与下行走梁7转动连接。每个走行支撑机构6可根据需要选择滚动轮组结构6的数量,通过本优选的滚动轮组结构6的结构,可保证对支撑骨架系统的支撑力,保证移动的稳定性。更优选的,围护钢架606上面设置有围护钢架叉耳605,下行走梁7下面设置有走行机构叉耳44,围护钢架叉耳605和走行机构叉耳44之间通过销轴连接。采用此种销轴连接的方式,可以在吊装装置前移的过程中,或者是吊装施工过程中有微小角度的前倾时,销轴连接处也能适应性的调整一定的角度,防止位于行走后端的走行轮组件脱离轨道。
为保证一体机按既定路线行走,走行系统还包括走行轨道20和梁面支撑垫梁21,走行轨道20包括轨道和轨道连接梁,其中,梁面支撑垫梁21,其间隔平行设置,沿滚动轮组结构6的移动方向铺设,轨道设置有两条,且互相平行,垂直设置在梁面支撑垫梁21,轨道之间间隔连接有轨道连接梁,轨道连接梁将轨道连接成为一个整体,由于连续梁26梁面会存在凹凸不平的情况,铺设有梁面支撑垫梁21,可以保持走行轨道20的平整性,走行轨道20则为滚动轮组结构6提供走行的轨道。本实施例中,结合图7所示,一根下行走梁7下面匹配有四组滚动轮组结构6,每两组互相平行,以保持下走行梁3的平衡性,互相平行的两组滚动轮组结构6分别运行在同一走行轨道20的两条轨道上,而每个一体机有两根下行走梁7,也匹配两条走行轨道20。本实施例中,轨道采用双拼I40工字钢定位焊接而成,轨道连接梁采用槽钢制作,两端与轨道焊接,走行轨道20可多节组拼,走行轨道20前端和后端均设置有轨道连接件,将轨道连接件通过螺栓固定即可将走行轨道20组拼在一起。走行轨道20的前端优选安装有支挡块,防止滚动轮组结构6走行超过设计位置。针对于上述走行轨道20,由于在钢筋笼18下放时,支撑骨架系统由于重力下压而会具有外倾的趋势,因此,在围护钢架606的外侧可设置有支撑卡具607,支撑卡具607上端与围护钢架606连接,下端延伸至走行轨道20外侧,其具有向内伸出的卡位柱,卡在走行轨道20的外侧面,对于本实施例采用工字钢制成的走行轨道20,卡位柱卡在工字钢翼缘的下面。
优选的,本实施例还设置有支点顶升支撑机构43,支点顶升支撑机构43包括顶升千斤顶4302,顶升千斤顶4302的固定端与支撑骨架系统的底面前端连接,在本实施例中是与下行走梁7的底面前端连接。由于一体机的前端吊装钢筋笼18,重量较大,因此一体机会呈现前倾的趋势,而通过顶升千斤顶4302可以向支撑骨架系统的前端施加向上的力,减缓一体机整体前倾的趋势。顶升千斤顶4302的固定端与支撑骨架系统连接,在一体机停止前移时,顶升千斤顶4302的活塞伸长,以施加向上的力,在一体机移动时,顶升千斤顶4302的活塞缩短,不影响滚动轮组结构6的移动。更优选的,本实施例还提供了一种能稳定一体机前端的支点顶升支撑机构43,结合图8和图9所示,还包括顶升分配梁4301和顶升下垫板4303,顶升千斤顶4302至少设置有2个,固定端的上面与顶升分配梁4301连接,伸缩端的下面与顶升下垫板4303连接,即2个或2个以上的顶升千斤顶4302的顶面通过顶升分配梁4301来连接,底端通过顶升下垫板4303来连接,与支撑骨架系统的连接是通过底面顶升分配梁4301来实现的,顶升千斤顶4302向上顶升的力量通过顶升分配梁4301来均匀的传递至下行走梁7,而顶升下垫板4303能匹配扣在走行轨道20的上面,结合图中所示,可以是顶升下垫板4303两侧有向下伸出的下垫板定位部,两块下垫板定位部之间的距离能匹配扣在走行轨道机构的上面,如此可防止发生偏移,同时还能将走行轨道20的支撑力均匀传递至顶升千斤顶4302。支点顶升支撑机构43同时还具有保护滚动轮组结构6的作用,避免工作载荷全部集中在滚动轮组结构6部分处受力。
以下对模板支撑系统作进一步的详细说明。本实施例提供了一种优选的底部承重机构,包括下前横梁1和下后横梁29;下前横梁1的两端分别与第一前吊带17的下端连接,下后横梁29的两端分别与后吊带25下端连接。
优选的,悬吊机构还包括至少1根第二前吊带31,第二前吊带31的上端穿过上承重梁15的中部,且能上下移动,下端与底部承重机构中部的前侧可拆卸连接。本实施例中,第二前吊带设置有2根,在上承重梁15中部的两侧呈对称设置,以更好的保证混凝土浇注时的承重能力,下端与下前横梁1的中部两侧可拆卸连接。但由于钢筋笼18在旋转时,可能会受到第二前吊带31的阻挡,因此,在进行钢筋笼18在旋转之前,需解除第二前吊带31与底部承重机构的固定结构,使第二前吊带向上移动,当钢筋笼18安装完成后,再向下移动第二前吊带,然后将其与与底部承重机构固定。为方便第二前吊带的移动,第二前吊带可采用柔性结构,如钢链或钢绞线等,第一前吊带17不会与钢筋笼18发生碰撞,可采用刚性结构,如钢筋、钢条等。调整第二前吊带31移动结构可设置于上承重梁15上,采用现有的传动装置均可实现,如ZL201610637468.0中的链式牵引装置。
优选的,对于第一前吊带17与支撑骨架系统上部前侧的两端可拆卸连接,以及后吊带25与支撑骨架系统下部前侧的两端可拆卸连接,是为了调整第一前吊带17和后吊带25悬吊底部承重机构的悬吊高度,以适应不同连续梁26节段不同的 梁高,对于悬吊高度的调整,本实施例提供了一种具体的结构,在上前横梁1和上后横梁19的上面对应设置有第一吊带分配梁,第一吊带分配梁的上方设置有第二吊带分配梁,第一吊带分配梁和第二吊带分配梁之间设置有吊带调节液压千斤顶,第一吊带分配梁和第二吊带分配梁的中间沿竖向贯穿有吊带调整槽,以容纳第一前吊带17/后吊带25穿过,吊带调整槽的前面和后面均设置有横向贯穿第一吊带分配梁/第二吊带分配梁的分配梁销孔,第一前吊带17和后吊带25上部间隔设置有多个吊带销孔,分配梁销孔和吊带销孔中能匹配穿入销轴以固定第一前吊带17/后吊带25。当需要调整第一前吊带17和后吊带25的长度时,先取出穿在第一吊带分配梁中的销轴,固定好穿在第二吊带分配梁中的销轴,吊带调节液压千斤顶顶升,第一前吊带17/后吊带25向上移动,顶升完成后,取出穿在第二吊带分配梁中的销轴,在第一吊带分配梁中插入销轴,吊带调节液压千斤顶回缩,第二吊带分配梁随之向下移动,然后在第二吊带分配梁中插入销轴,取出穿在第一吊带分配梁中的销轴,重复上述步骤直至完成第一前吊带17/后吊带25长度的调整。
本实施例还提供了一种优选的、方便拆装的模板装置,对于浇筑连续梁的模板,按照常规设计,包括外侧模、内模和底模46,底模46位于外侧模的底部,钢筋笼设置在外侧模之间,其中间有通道设置内模。本实施例提供了方便拆模和合模的外侧模及内模,为实现外侧模的快速拆模和合模,在外侧模两侧设置有外侧模支撑机构,为实现内模的快速拆模、合模及向前移动,在内模内侧设置有内模支撑机构。
