Description

一种城市轨道交通工程新型铺轨机及其施工方法 [技术领域]
本发明涉及工程技术科学，具体是一种城市轨道交通工程新型铺轨机及其施工方法。
[背景技术]
目前我国城市轨道交通工程轨道施工中，采用的铺轨机设备主要有拼装固定门型结构、人工及液压定距变跨门型结构和自动检索电动无极变跨门型结构三种型式。三种结构形式的铺轨机都需要铺设临时走行轨供铺轨机走行。临时走行轨是预先铺设在正线两侧的隧道侧壁或结构底板上，轨距一般为2800mm、3000mm、3100mm、3800mm等几种，由特制的钢结构支墩把临时走行轨固定在隧道侧壁或结构底板上。由于城市轨道交通工程地下线隧道结构空间狭小，安装临时走行轨让狭小的空间减小了作业空间，轨道施工时铺排铺设需借助于侧向支撑来保证轨道状态，侧向支撑经常和临时走行轨发生冲突，使得正线轨道轨排铺设施工空间减小。隧道结构的不同，临时走行轨安装位置也不同(圆形隧道安装在侧壁上，马蹄形隧道和矩形隧道安装在结构底板上，有的结构就需要一侧安装在侧壁上、一侧安装在结构底板上)，无论何种安装方式都占用道床结构位置空间，使得道床混凝土施工由一次完成变成两次施工(先浇筑整体道床，再浇筑道床水沟)，导致整体道床与水沟形成混凝土结构缝；随着正线轨道的铺设不断地向前循环推进，大量的临时走行轨循环倒运使用，使得正线轨道施工无论是空间上还是时间上都产生影响；同时安装临时走行轨需要在建筑结构物上打孔固定走行轨支墩，一定程度上影响结构的外观和性能；当遇到车站、人防门等特殊地段时，由于结构边界的限制使得临时走行轨轨距变化造成临时走行轨的不连续，既占用正线轨道的安装位置，还由于铺轨机变跨要求而中断正线轨道施工作业，不同程度地占用轨道施工有效时间和空间；由于需要铺设临时走行轨道，给正线轨道施工增加了作业工序，增加了施工投入，加大了施工成本和人员劳动强度。
综上所述，现有的轨道施工铺轨机在实际应用中虽然广泛采用，但给正线施工带来诸多制约和影响。在现代轨道交通工程铺设施工技术飞速发展时期，板式道床、预制拼装结构等结构将成为主流。为满足铺轨施工效率的更高需求，铺轨设备的自适应性、全功能型、灵活性都有更高的要求，为正线铺轨提供更大的作业空间和有效作业时间等成为必然的趋势，因此开发一种不需要铺设临时走行轨就能实现隧道内轨道材料、预制品、拼装结构等材料的吊装、转运以及整机免解体快速转场、简单分拆可实现长途运输转移的节能环保的新型铺轨机成为必然的趋势、当务之急。

实例二：新型铺轨机预制轨道板吊运及安装施工
城市轨道交通道床板铺设施工一般是在区间道床板垫层施工完毕后进行，道床板为预制混凝土板，长度一般为5800mm(普通版)，曲线调整板长度一般为4500mm—5000mm，为了便于预制板运输，一般铺设25m—50m道床板后及时安装钢轨扣件形成运输通道，当轨道板铺设达100m以上时，对轨道板和轨道状态进行调整，在轨道板下灌注自密实混凝土或其他砂浆材料对轨道板及轨道状态进行固定，形成轨道线路。因此铺设轨道板是关键工序。
1、轨道板卸车载、吊装、移动和就位
a、新型铺轨机抬升：参见图10-38，将新型铺轨机运行到准备卸车位置停车(新型铺轨机1号抬升行走台车处在已安装轨道板并形成正线轨道钢轨端部5米位置，2号抬升行走台车处在未安装轨道板的垫层位置上)。分别操作1、2号抬升行走台车的液压驱动油缸38使竖向支撑装置的水平伸缩导柱39向线路两侧伸出，当同一断面伸出的内部空间满足运输平板车和轨排宽度要求时停止并锁闭。分别操作1、2号抬升行走台车的竖向支撑装置的液压驱动油缸41、42驱动导柱43、44向下伸出，使其平稳地支撑在垫层面(如果垫层面位置不合适则向外调整水平伸缩满足合适位置，地面不平时进行支垫)，确认稳妥后继续同步操作1、2号抬升行走台车的竖向支撑装置向下伸出，由于垫层面的制约向下伸出使得新型铺轨机产生向上抬升的状态，当新型铺轨机抬升到满足吊装平板车上的轨道板高度后停止抬升，分别调整新型铺轨机8个支撑脚的受力状态，使其均匀受力，并使新型铺轨机属于水平状态，完成后停止操作并锁闭；

2、轨道板喂料、轨道板起吊、移动、安装:
a、参见图10-37，指挥轨道牵引车推送轨道板运输平车缓缓进入新型铺轨机下；
b、参见图10-37，当轨道板完全进入新型铺轨机下方时停止推送，制动；
c、参见图10-37，分别操作起重吊装小车9的走行牵引卷扬机47对起重吊装小车9的吊点位置进行调整，无误后停止操作；
d、分别操作小车9放下吊装扁担，使扁担挂钩和轨道板牢固连接；
e、参见图10-37，一切确认无误后，解除平板车上的轨道板约束，同步操作起重吊装小车9使吊装小车缓缓将平板车上的轨道板吊起，当轨道板完全脱离平板车及其支垫轨道板的垫木后停止操作。检查轨道板是否脱离支垫，是否高出支垫物而影响走行？个别调整高度，一切无误后锁闭操作；
f、参见图10-37，同步操作起重吊装小车移动控制装置使吊装小车吊装轨道板沿连接桁架梁向安装方向移动(见图54)，当到达安装位置上方时停止移动，操作吊装小车吊装控制将轨道板缓缓下降，平稳地摆放在安装位置，此时可通过移动吊装小车使轨道精确就位；
g、参见图10-37，轨道板摆放完成后拆除吊装扁担与轨道板的连接，同步提升吊装扁担至上限位高度，同步移动吊装小车到运输平板车轨道板位置继续吊装下一块轨道板；
h、重复操作上述c、d、e、f、g步骤完成第二块、第三块等轨道板的吊装；
i、当新型铺轨机下方空间轨道板全部安装完成后，停止操作；
j、参见图10-37，指挥轨道牵引车把正线临时用钢轨运送到新型铺轨机下；
k、参见图10-37，同步操作起重吊装小车9吊起钢轨并纵向移动到轨道板的安装位置，缓缓降下钢轨平稳地摆放在轨道板的承轨槽垫板上；
l、参见图10-37，按规定要求用扣件扣紧钢轨，使正线钢轨形成通道。
3、新型铺轨机前移、抬升，准备新位置吊装：
a、参见图10-37，同步操作新型铺轨机1、2号抬升行走台车的竖向支撑装置的液压驱动油缸41、42驱动导柱43、44向回收缩，使新型铺轨机缓缓下降，将新型铺轨机1号抬升行走台车的走行小车5的轨道走行轮平稳地停放在正线轨道上停止操作。操作2号抬升行走台车的履带走行机构，使其下降平稳地支撑在垫层面上，继续操作1、2号抬升行走台车的竖向支撑控制装置使8个支撑脚脱离垫层面回缩到上止点位置停止操作并锁闭；
b、同步操作新型铺轨机走行控制装置使新型铺轨机向无轨道板方向走行，当1号抬升行走台车走行小车距离正线轨道钢轨端头5米时停止走行；
c、同步操作1、2号抬升行走台车的竖向支撑控制装置使支撑脚平稳地支撑在垫层面上，继续操作使新型铺轨机整体抬升到吊装轨道板的位置停止操作，调平新型铺轨机使新型铺轨机处于水平状态，检查新型铺轨机8个支撑脚支撑是否稳固可靠，一切无误后锁闭操作；
d、重复上述一、二、三各步骤完成再次轨道板吊装作业和钢轨安装作业。最后完成轨道板的铺装作业。
实例三：新型铺轨机作业面转场
参见图20-37,轨道施工一般是以铺轨基地为中心，上、下行线双向进行施工。道岔作为轨道转向的关键设备是提前进行施工的。新型铺轨机作业面转移就是利用已铺设完成的道岔和单渡线实现的，作业面转移有3种位置，途中新作业面1、新作业面2和新作业面3：
1、将新型铺轨机的1、2号抬升行走台车竖向支撑装置的水平伸缩装置收回到走行转移位置，将竖向支撑装置收回到上限位转移走行位置锁闭。拆除新型铺轨机供电电源，将电缆收卷到电缆卷线盘内。拆除新型铺轨机轨道走行轮与走行驱动减速器的连接，使其处于空挡状态。将新型铺轨机和轨道牵引车用连接拖杠进行连接。启动轨道牵引车，让轨道牵引车牵引新型铺轨机缓缓驶向道岔2位置。首先轨道牵引车牵引新型铺轨机通过道岔2，当新型铺轨机尾部到达道岔2信号机位置时停止走行，扳动道岔1和道岔2开通道岔侧向通行轨道，启动轨道牵引车，让轨道牵引车推送新型铺轨机进过道岔2、道岔1进入正线1，到达新作业面1，完成转场作业；
