Description

一种全护筒工法施工装置 本申请要求于 2011 年 9 月 19 日提交中国专利局、 申请号为 201110278363.8、 发明名称为"一种全护筒工法施工装置"的中国专利申请 的优先权， 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及工程机械领域， 特别涉及一种全护筒工法施工装置。
背景技术
现代建筑工程的施工过程一般均以桩基础施工开始， 因此， 基础成桩 施工显得尤为重要。 在诸多的基础成桩施工工法中， 全护筒施工是应用较 为广泛的一种重要的施工工法。 全护筒施工是指， 通过将多个一定长度的 护筒节连接在一起， 在整个桩深的范围全程压入或者压入至稳定的地层， 从而配合人工、 沖抓斗、 旋挖、 沖击钻等方法取土成孔， 成孔完成后再将 护筒拔出的施工方法。 由于护筒对地层的支撑和密封作用， 避免了桩孔的 坍塌、 缩颈、 扩径等问题， 避免使用泥浆来平衡地下水压从而避免了泥浆 污染， 同时可以避免地下水进入护筒内， 为打桩设备创造良好钻进条件， 全护筒施工形成的孔壁较为规则， 从而能够提高成桩的承载力。
目前， 下压和起拔护筒的主要通过以下几种方法实现：
振动锤； 利用振动锤的激振力， 使护筒下端的土层液化， 通过减小土 壤与护筒筒壁之间的阻力实现护筒的下压； 起拔护筒同样利用振动锤的激 振力减小护筒筒壁与地层的摩擦， 通过吊车实现护筒起拔。
旋挖钻机； 通过在旋挖钻机的动力头上安装护筒驱动器， 利用动力头 的扭矩和旋挖钻机加压装置提供的压拔力实现护筒的下压和起拔。
全回转钻机； 专门的护筒下压和起拔设备， 通过夹紧机构抱紧护筒进 行下压、 起拔和回转的方式实现护筒的下压、 起拔。
沖击锤； 利用重力的沖击力实现护筒的下压。
上述几种方法均有各自的缺点， 具体地：
振动锤驱动力较小， 只适用于较软的土质、 沙质地层， 由于只有垂直 方向的作用力， 无法在岩层等硬质地层中使用；
旋挖钻机动力头的扭矩和下压力有限， 一般为数十吨， 但护筒的埋深 一般为数十米， 直径为 0.8m-3.0m, 下压和起拔护筒的力要求为百吨以上， 所以该方法仅适用于埋深较浅的护筒施工， 或者是最初深度的护筒下压； 全回转钻机利用油缸实现对护筒的下压、 起拔， 用马达驱动护筒的旋 转实现对地层的切割， 但其无法同时实现钻进取土， 需要配合沖抓斗或者 旋挖钻机施工， 不仅施工效率较低， 且在施工过程中全回转钻机和钻进取 土设备需要单独提供动力， 使得施工成本较高；
沖击锤由于其噪音只适用与野外的作业， 且只具有下压护筒的能力， 不具有起拔护筒的能力。
因此， 开发一种专用于护筒下压和起拔的全护筒工法施工装置， 使其 具有足够的下压力和起拔力， 且具有较高的施工效率和较低的生产成本， 就成为本领域技术人员亟须解决的问题。

在进行全护筒施工时， 首先对搓管钻机底盘下的地面进行加固、平整， 通过调整取土设备的主机位置使取土设备的钻进中心、 搓管钻机的主卡和 副卡的中心对正孔位； 首先使用取土设备的工作部件钻进适当的深度， 然 后利用取土设备的卷扬吊装护筒到搓管钻机内， 连接护筒到搓管钻机的动 力头上的护筒驱动器， 利用动力头的动力将护筒压入一定深度， 而后使用 搓管钻机进行搓管钻进； 取土设备的旋挖和搓管钻机的钻进交替进行， 达 到设定深度后， 吊入钢筋笼及混凝土导管， 灌注混凝土， 同时起拔护筒， 保持混凝土的灌注高度高于护筒的下端， 直到成孔。

具体实施方式
本发明的核心是提供一种全护筒工法施工装置， 作为护筒下压和起拔 的专用设备， 其具有足够的下压力和起拔力， 且具有较高的施工效率和较 低的生产成本。
为了使本技术领域的人员更好地理解本发明的技术方案， 下面结合附 图和具体实施方式对本发明作进一步的详细说明。
请参考图 1 , 图 1为本发明所提供的全护筒工法施工装置的结构示意 图。
本发明提供了一种全护筒工法施工装置， 该全护筒工法施工装置包括 取土设备 1和搓管钻机 2, 其中， 搓管钻机 2通过连接部件安装于取土设 备 1的机身， 显然地， 搓管钻机 2应该安装在取土设备 1的固定部分， 该 固定部分在施工过程中相对于地面应该是静止的， 例如搓管钻机 2可以安 装在取土设备 1的底盘 22上。搓管钻机 2的动力源为取土设备 1的动力元 件。
需要指出的是， 在本发明所提供的全护筒功法施工装置中， 其中的搓 管钻机 2可以为本领域中常规使用的各种搓管钻机， 也可以是在原有搓管 钻机的基础上进行改进， 以更适应全护筒工法的搓管钻机， 本发明所提供 的搓管钻机不仅包括文中所涉及的部件， 还应该包括完成工作过程所必须 的其他零部件， 例如为搓管钻机 2提供压拔力的压拔油缸、 为搓动护筒提 供动力的错管油缸等。搓管钻机 2的工作原理与传统的搓管钻机基本相同。 具体地， 在全护筒工法中， 搓管钻机 2的作用为下压和起拔护筒， 动作步 骤可以设计为：
S11搓管钻机 2的副卡夹紧；
S12搓管钻机 2的主卡 26打开；
S13搓管钻机 2的压拔油缸升（降）至上止点 （下止点；)；
S14主卡 26抱紧护筒；
S15副卡打开；
S16搓管钻机 2的搓管油缸搓动， 同时压拔油缸下压（起拔）； 压拔油 缸到达下止点（上止点）后停止下压（起拔）， 搓管油缸停止搓动， 开始步 骤 S11 , 如此循环， 达到护筒节的上端（下端）后， 安装（拆解）护筒节， 继续循环， 直到达到设计深度（护筒全部取出）。
在进行全护筒施工时，首先对搓管钻机 2的底盘 22下的地面进行加固、 平整， 通过调整取土设备 1的主机位置使取土设备 1的钻进中心、 搓管钻 机 2的主卡 26和副卡的中心对正孔位；首先使用取土设备 1的工作部件钻 进适当的深度， 然后利用取土设备 1的卷扬吊装护筒到搓管钻机 2内， 连 接护筒到搓管钻机 2的动力头上的护筒驱动器， 利用动力头的动力将护筒 压入一定深度， 而后使用搓管钻机进行搓管钻进； 取土设备的旋挖和搓管 钻机的钻进交替进行， 达到设定深度后， 吊入钢筋笼及混凝土导管， 灌注 混凝土， 同时起拔护筒， 保持混凝土的灌注高度高于护筒的下端， 直到成 孔。
这样， 该种全护筒工法施工装置在取土设备 1上的附着搓管钻机 2 , 并利用取土设备 1作为搓管钻机 2的动力， 从而降低了生产成本； 同时， 在工作过程中，利用取土设备 1的起吊和行走能力实现便捷的安装和移动， 配合取土设备 1自身的钻进能力实现高效钻进成孔，显著提高了施工效率。
请参考图 2和图 3, 图 2为本发明所提供的全护筒工法施工装置中搓 管钻机在主视方向的结构示意图； 图 3为图 2所示搓管钻机在俯视方向的 结构示意图。
在一种具体实施方式中， 本发明所提供的全护筒工法施工装置， 其连 接部件可以为搓管钻机 2的接口座 21; 这样， 通过搓管钻机 2的既有结构 实现连接， 筒化了设备的结构， 进一步降低了生产成本。 显然地， 上述连 接部件也不局限于为搓管钻机 2的接口座 21, 也可以为单独设计的结构， 只要能够实现搓管钻机 2与取土设备 1的可靠连接即可。
上述搓管钻机 2的底盘 22上可以设置有压台 221, 所述接口座 21包 括位于所述压台 221上方且抵靠或者远离所述压台 221的压块； 所述接口 座 21远离所述压块的一端与所述取土设备 1固定连接，其靠近所述压块的 一端与所述搓管钻机 2的底盘 22转动连接， 搓管钻机 2的底盘 22相对于 接口座 21在竖直方向摆动。在搓管钻机 2下压护筒时，搓管钻机 2的压拔 油缸收缩， 底盘 22被抬起， 底盘 22整体相对于接口座 21转动， 转过预定 角度后， 底盘 22上伸出的压台 221碰到并抵靠于接口座 21的压块， 由于 接口座 21与取土设备 1固定连接而不可旋转， 接口座 21与取土设备 1连 为一体， 通过取土设备 1的自身重量压制底盘 22的继续抬升， 这样， 在搓 管钻机 2的钻进过程中， 利用取土设备 1的重量来平衡下压护筒时产生的 反作用力， 土设备替代了搓管钻机 2的配重，从而进一步降低了施工成本。
显然地， 上述压块应该是相对于接口座 21向外伸出的， 相应地， 压台
221也应该是相对于底盘 22向外伸出的。
压台 221的数量可以为两个， 两压台 221分别位于搓管钻机 2的底盘 22的相对的位置， 相应地， 压块的数量也可以为两个， 两压块分别位于接 口座 21的相对位置， 与压台 221的位置相匹配。 显然地， 压台 221和压块 的数量也不局限于设置有两个， 也可以设置有三个、 四个或者更多个， 多 个压台 221可以均勾分布于搓管钻机 2的底盘 22上，多个压块也可以均匀 分布在接口座 21上。
需要指出的是， 上述压台 221与压块相互抵靠或者分离是指， 在全护 筒工法施工装置第一种工作过程中， 搓管钻机 2的底盘 22相对于接口座 21运动， 当运动至预定位置时，压台 221抵靠于压块上，压块限制压台 221 的进一步运动； 而在全护筒工法施工装置进行第二种工作过程时， 搓管钻 机 2的底盘 22相对于接口座 21反向运动， 压台 221脱离压块并逐步远离 压块。
接口座 21与取土设备 1固定连接可以通过本领域中常规的方法实现， 例如两者可以通过螺栓可拆装地连接， 也可以通过焊接等方式固定连接。
接口座 21与搓管钻机 2的底盘 22的转动连接结构可以具体为， 接口 座 21上设置有挂轴 212 , 挂轴 212沿搓管钻机 2的底盘 22的横向设置， 搓管钻机 2的底盘 22上安装有挂接于挂轴 212的挂钩 222; 当搓管钻机 2 下压护筒时， 压拔油缸收缩， 底盘 22被抬起， 挂钩 222绕挂轴 212转动， 从而实现底盘 22整体相对于接口座 21转动， 该种转动连接的结构较为筒 单， 且加工方便， 安全可靠。
接口座 21与底盘 22的转动连接也不局限于上述挂轴 212和挂钩 222 的形式， 也可以为本领域中常规使用的其他能够实现转动的方式， 例如接 口座 21可以直接铰接于底盘 22上， 铰接轴与上述挂轴 212的方向相同， 即沿搓管钻机 2的底盘 22的横向设置。
上述接口座 21还可以包括连接块 213, 搓管钻机 2的底盘 22上开设 有沿其纵向开设的滑槽， 连接块 213滑动安装于滑槽， 挂钩 222安装于连 接块 213的末端； 这样， 接口座 21通过连接块 213安装于底盘 22上， 搓 管钻机 2在水平方向具有一定的自由度，而护筒的位置和接口座 21的位置 是固定的， 可以通过调整接口座 21相对于底盘 22的位置， 调节护筒的位 置， 从而保证了护筒下压时的位置精度。
需要指出的是，文中所提到的搓管钻机 2的底盘 22的横向是指，垂直 于搓管钻机 2前进方向的方向， 纵向是指沿搓管钻机 2前进方向的方向。
上述连接块 213上可以开设有条形孔， 该条形孔沿搓管钻机 2的底盘 22的纵向开设， 定位销轴通过条形孔插入连接块 213; 连接块 213可伸缩 的插入在搓管钻机 2的底盘 22内，通过定位销轴固定连接，在工作状态时， 定位销轴插入条形孔内， 既保证了搓管钻机 2在水平方向的自由度， 又避 免了连接块 213从滑槽内脱落， 保证了设备的工作可靠性。
在连接块 213上还可以开设有定位圓孔， 定位销轴可选择地插入该定 位圓孔中。 在全护筒工法施工装置进行转场运输时， 从条形孔中拔出定位 销轴，取土设备 1的底盘后退带动连接块 213从搓管钻机 2的底盘 22中抽 出一定距离， 而后将定位销轴 2插入到定位圓孔中， 实现连接块 213与搓 管钻机 2的底盘 22的固定连接， 从而实现整个搓管钻机 2的移位。
显然地， 连接块 213上也可以不开设上述定位圓孔， 在转场时， 将搓 管钻机 2和取土设备 1拆分后分别运输。
上述接口座 21还可以包括至少两个连接臂 214,所述连接臂 214沿搓 管钻机 2的底盘 22的横向设置， 接口座 21通过连接臂 214与取土设备 1 固定连接， 以便较为方便地实现接口座 21和取土设备 1的固定连接。
上述连接臂 214与取土设备 1的固定连接可以为销轴连接的方式， 具 体地， 可以使用两排销轴实现多点固定， 以便保证连接可靠性。
上述接口座 21可以为 U形的框架式接口座， 搓管钻机 2的连接工作 部分的连接部， 在水平方向上位于该框架内； 当搓管钻机 2的两个搓管油 缸交替伸缩搓动护筒时， 搓管钻机 2在连接端的方向交替摆动， 由于接口 座 21为 U形的框架式结构， 搓管钻机 2的连接端交替撞在接口座 21上， 而接口座 21通过销轴和连接臂 214与取土设备 1的底盘固定连接，在水平 面内接口座 21与取土设备 1的底盘形成一体， 从而实现限制搓管钻机 2 的摆动， 提高了设备的工作稳定性。
还可以对本发明所提供的全护筒工法施工装置进行进一步的改进。 请参考图 4, 图 4为图 2所示搓管钻机的底盘在俯视方向的结构示意 图。
在另一种具体实施方式中， 本发明所提供的全护筒工法施工装置， 其 搓管钻机 2的固定副卡 23通过转动连接部件转动安装于搓管钻机 2的底盘 22, 转动连接部件的转轴沿搓管钻机 2的底盘 22的横向水平设置； 这样， 固定副卡 23保持在水平方向的固定以实现对护筒的抱定，同时在垂直方向 可实现转动， 在压拔油缸下压提起搓管钻机 2的底盘 22时， 固定副卡 23 不随底盘 22—起被提起， 从而避免了搓管钻机 2与护筒之间的干涉。 转动连接部件包括转轴和轴座， 轴座固定于搓管钻机 2的底盘 22 , 转 轴通过轴承安装于轴座； 当压拔油缸下压油缸时， 搓管钻机 2 的底盘 22 远离取土设备 1的一端被提起， 由于护筒插入地下可以认为是固定不动， 此时上述转轴在轴座内转动，从而带动固定副卡 23在竖直面上转动，避免 搓管钻机 2的底盘 22与护筒之间的干涉；该种转动连接部件的结构较为筒 单， 力。工较为方便。
转动连接部件也不局限于上述转轴在轴座中转动的形式， 只要能够实 现固定副卡 23相对于搓管钻机 2的底盘 22在竖直面上的摆动， 转动连接 部件可以有多种形式，例如令固定副卡 23与搓管钻机 2的底盘 22铰接等。
上述转轴的数目可以为两个， 两转轴分别设置于固定副卡 23 的两端 点。
固定副卡 23可以为抱紧面呈光滑弧面的弧板，弧板的外部顶端安装有 支板； 光滑弧面能够降低教工难度， 同时， 在弧板的外部顶端设置的支板， 能够避免在固定副卡 23抱紧护筒时，转轴承受全部的剪切力， 降低了转轴 的受力要求。
本发明所提供的搓管钻机 2的变径移动副卡可以为整体式结构， 变径 移动副卡可拆装地安装于搓管钻机 2的移动副卡 25。 具体地， 变径移动副 卡上设有安装轴，移动副卡 25上开设有安装孔，安装轴插入所述安装孔中， 所述安装轴径向插装有定位销； 这样， 当护筒的尺寸改变时， 将变径移动 副卡拆下， 同时换上符合尺寸要求的变径移动副卡， 该种结构使得更换变 径移动副卡的过程较为方便， 提高了设备的适用性。
上述搓管钻机 2还可以包括轴套， 安装轴沿轴套的径向插装于轴套， 定位销同轴地插装于轴套， 以便提高安装轴的安装可靠性。
上述搓管钻机 2的主卡 26和夹持臂 27两者中的一者安装有限位杆 29, 另一者设置有与所述限位杆 29抵靠或者分离的挡块 210; 当夹持油缸拉动 夹持臂 27打开主卡 26时， 夹持臂 27绕其转动轴转动到一定程度时，上述 限位杆 29挡住夹持臂 27, 夹持臂 27继续打开从而推动限位杆 29运动， 进而推动整个主卡 26的规则打开， 使得主卡 26的打开更加规则， 保证了 主卡 26打开的可靠性。 显然地， 挡块 210 可以为夹持臂的既有结构或通过开设在夹持臂 27 上的凹槽实现， 也可以为另外设置的元件。
本发明所提供的全护筒工法施工装置， 其取土设备 1为旋挖钻机或者 抓斗起重机， 也可以为其他能够提供动力， 且能够实现取土钻孔作业的工 程机械。
以上对本发明所提供的一种全护筒工法施工装置进行了详细介绍。 本 的说明只是用于帮助理解本发明的方法及其核心思想。 应当指出， 对于本 技术领域的普通技术人员来说， 在不脱离本发明原理的前提下， 还可以对 本发明进行若干改进和修饰， 这些改进和修饰也落入本发明权利要求的保 护范围内。
