现今随着大直径盾构机的逐渐普及应用，对管片提出了高强度、高精度、高质量、高抗渗性以及高外观质量的要求，因此对于管片的吊运也提出了采用真空吸盘这一要求更为严格的方法以满足施工要求。

具体实施方式
参见各附图，一种适用于大型盾构机的卷扬式管片吊机，包括设置于并行的两条运行轨道1之间的包含有第一从动小车22的管片吊运装置2、用于驱动管片吊运装置2沿着运行轨道1移动的动力小车3。管片吊运装置2作为管片吊 机的卷扬机构23部分，动力小车3作为管片吊机的驱动部分。
动力小车3为常规技术：如附图1所示：主要由驱动三合一电机、齿轮传动、驱动链轮、设置于运行轨道1两侧的墙板、可调车轮组等组成。可调车轮是通过调整车轮组上调节螺母，调整链轮与滚子链的间隙，使小车运行平稳。

如图4所示，两组卷扬机构23呈180°旋转对称布置，两套卷扬机构23可以实现单独起升动作和同时起升动作，吊运管片时将卷扬机构23切换为同时起升模式即可。具体的，每个卷扬机构23包括转动设置于两个搬运横梁21之间的卷筒组231、固定在两个搬运横梁21之间的用于安装定滑轮241的定滑轮梁24、安装于相应的搬运横梁21上的起升制动电机232、起升减速箱233、导绳器、吊钩组、接线箱等。
如图5所示，每个搬运横梁21上具有安装卷筒组231的卷筒轴承座211，卷筒轴承座211至少部分沉入到搬运横梁21结构内，卷筒轴承座211上具有轴承孔212，轴承孔212边缘最低点低于搬运横梁21上表面。
如图2-4所示，每个卷扬机构23的卷筒组231采用双联卷筒，卷筒组231两端通过固定在定滑轮梁24上的两个定滑轮241同时向下出绳，因而每个卷筒组231具有两个吊钩组，可以实现两个吊钩组同步起升、下降。

本实施例卷扬机构23具有如下优点：
A 采用两套相同卷扬机构23含有起升电机1-7.5t、起升电机2-7.5t,两组卷扬机构23呈180°旋转对称布置，四个吊钩同时起升起吊真空吸盘，起升运行平稳，冲击小，不仅对管片吊运提供了安全保障，满足了施工进度要求，而且有效地提高了管片吊机的使用寿命；
B 两套卷扬机构23定滑轮梁下方安装有两个喇叭口插管242，待抓取机构6真空吸盘抓取管片牢固后，四个吊钩组同时起升至上极限位置，此时抓取机构6上两个导杆61插入喇叭口插管242内，使抓取机构6、管片与卷扬机构23形成刚性定位，从而保证运行过程的同步性，起到防摇摆的功能，有效地满足管片的快速运输；
C 起升制动电机232、起升减速箱233、制动器等与卷筒组采用L形布置。每组卷扬机构23的起升制动电机232、起升减速箱233、制动器采用法兰盘连接，并且设置在相应搬运横梁21的外侧。起升减速箱233与升制动电机232相对于水平面倾斜3°，从而避免与从动小车发生干涉，便可使卷扬机构23长度尺寸如图5中尺寸L1压缩至极限，使管片吊机整机运行范围大大提高，更好地满足盾构机内管片运输施工要求；
D 如图5所示，搬运横梁21,其中卷筒轴承座采用半沉式结构形式，即轴承座沉入到卷扬机构23横梁结构内，在保证小车架强度、刚度的同时，极大的减小了卷扬机构23的净高尺寸，不仅提高盾构机内高度方向空间利用率，而且增大起升高度，如附图8所示，减小C尺寸，使管片吊机在吊运管片时与运输车上摆放的管片留有足够的安全空间尺寸H，保证了管片吊机盾构机内拥有良好的通过性。
如附图1、7所示，适用于大型盾构机的卷扬式管片吊机还包括物料吊运装置4，用于吊运盾构机内设备维护物品，例如润滑油桶等。采用模块化设计，其拆装方便，可维护性好，作为管片吊机的辅助吊机部分，也是大直径盾构机内不可或缺的一部分。物料吊运装置4包括分别沿着两条运行轨道1移动的第二从动小车41、两端部分别通过水平的物料吊连接轴44连接在两个第二从动小车41之间的物料吊轨道42、能够移动设置于物料吊轨道42上的环链葫芦43， 物料吊连接轴44的轴心线与搬运横梁21的长度方向相空间直。
如附图1、6所示，管片吊运装置2在运行轨道1的长度方向上位于物料吊运装置4与动力小车3之间，物料吊运装置4与管片吊运装置2之间、以及管片吊运装置2与动力小车3之间分别通过能够在至少两个相交的平面方向拥有自由度的联接装置5连接。
联接装置5包括位于中间的连杆51、位于连杆51两端的铰接头52，连杆51的端部与铰接头52之间通过竖直的第一联接轴53转动连接，铰接头52上还具有用于转动连接的水平的第二联接轴54，第一联接轴53的轴心线、第二联接轴54的轴心线与搬运横梁21的长度方向分别空间垂直。此联接装置具有两个方向的自由度，在管片吊机运行过程中，可满足上下斜坡及盾构机R＝900m的转弯半径。
详细的：
1、整机结构分为三大部分：动力小车部分、管片吊运装置部分、物料吊运装置部分。具有安装、维护方便，结构美观，操作简单等优点；
2、动力小车部分：采用SEW品牌KAF标准系列三合一电机驱动，其防护等级IP55，F级绝缘等级，减速器输出扭矩经过外吃啮合直齿轮传动，动力传至链轮轴，通过链轮与固定于H型钢运行轨道下翼缘板上的滚子链啮合，实现水平运动；并通过调节可调车轮组上螺钉，调节链轮与滚子链间距，使小车运行平稳；
3、管片吊运装置部分：由卷扬机构23及四套第一从动小车22组成。其中卷扬机构23采用两套相同卷扬机构23(含有起升电机1-7.5t、起升电机2-7.5t),呈180°旋转对称布置。每套机构均含有起升制动电机232、起升减速箱、卷筒组、定滑轮梁、导绳器(两套)、吊钩组(两套)；四套第一从动小车22结构相同，具有良好的互换性。
a)为提高管片吊机通过性，主要采取以下措施：A、起升制动电机232选用SEW品牌KAF标准系列产品，与墙板采用法兰连接；B、起升减速箱233采用SEW品牌MC系列标准产品，与制动电机采用法兰连接，通过使用支撑力臂侧挂与小车横梁两侧；C、卷筒组轴承座211采用半沉式结构，使小车整体高度大大降低，如附图8所示，从而减小吊钩中心与轨道踏面间距尺寸C，加大了管片运输的安全通过尺寸H。
b)为使管片吊运平稳，主要采取以下措施：A、两套相同卷扬机构23，呈180°旋转对称布置，卷筒组采用双联卷筒，实现四吊钩组同时起升、下降；B、卷扬机构23定滑轮梁下方设置喇叭口插管242，真空吸盘抓取管片上升上极限位置时，真空吸盘自带的两个导杆61插入喇叭口插管242，起到刚性定位作用，从而避免快速运输过程中管片摇摆；
c)为适应施工隧道内潮湿、经常有泥水喷溅、40℃环境温度等恶劣环境因素，主要采取以下措施：A、运行三合一电机采用SEW品牌KAF标准系列产品，其防护等级IP55,F级绝缘等级；B、起升制动电机232采用SEW品牌标准系列电机，其防护等级IP55,F级绝缘等级，带有超速开关、编码器、强冷风机；C、起升高度限制器、载荷限制器均采用防护罩对其进行防护；D、电控接线箱采用防护等级为IP55的电控柜，电缆走线均在密封线槽内，过渡段电缆均采用金属软管，对电缆起到保护作用。
d)为满足管片吊机上下斜坡、盾构机最小900米转弯要求，主要采取以下措施：A、将管片吊机分为三大部分，即动力小车驱动部分、卷扬机构起升部分、物料吊运装置辅助吊机部分，三部分通过联接装置铰接连接；B、起升制动电机232、起升减速器采用法兰连接，侧挂与小车架两侧，降低整机高度，减小整机长度。
本发明主要分为运行驱动、起升吊运机构、辅助吊机三大部分，具有加工制造成本低，安装、维护方便，起重量大，起升、下降平稳、冲击小，运行速度快，结构防护等级高，能够很好地满足恶劣的隧道施工环境，达到日进10环的隧道施工进度要求，从而极大地提高生产效率。满足大直径盾构机内空间狭小、施工环境恶劣、管片吊运速度快、管片自重大等因素的施工进度要求。因此适用于大型盾构机的卷扬式管片吊机应运而生了，面对国外对于大型盾构机的技术垄断，国人在此方面的技术创新、突破，摆脱国外技术制约的重要性不言而喻。
如上，我们完全按照本发明的宗旨进行了说明，但本发明并非局限于上述实施例和实施方法。相关技术领域的从业者可在本发明的技术思想许可的范围内进行不同的变化及实施。
