Description

一种桩孔清理机构 技术领域
本发明涉及到桩基工程施工中地下成孔的一种设备，尤其涉及到把旋挖钻机和反循环钻机有效结合的一种龙门式带链板输送机和不间断管道输送的一种桩孔清理机构。
背景技术
在桩基成孔土层中有回填层、流沙层、软硬岩层、废基础等，目前在大孔径、超深孔桩基施工中所用的设备主要是正反循环钻机和旋挖钻机等设备。存在的问题是：由于功率大、扭矩大旋挖钻机在中小于100m的浅孔时有明显优势。但大于100m的深孔时由于提升钻斗时间长、耗能大，所以成孔效率低。
反循环钻机在施工中要把地下各岩体刻取研磨至碎块状后通过钻杆将土渣浆体排除，在浅孔施工效率低，在深孔时比旋挖钻机相比具有一定优势。现有正反循环钻机多采用连接钻杆的方式施工，在更换维修钻头时需要把地下钻杆一节一节的提升，再把每一节钻杆连接放置地下，耗时长、增加劳动强度。由于钻杆细，扭矩小造成施工效率慢。
成孔后泥渣的清理问题一直没有得到有效的解决。
发明内容
本发明是要解决现有技术存在的上述问题，提供一种桩孔清理机构。大大增加了成孔后泥渣的清理。
本发明涉及的桩孔清理机构，其特征是：包括固定架一端与主车体连接，另一端安装在空心轴上，空心轴安装在管道轮架上，管道轮架可在空心轴上左右滑动，管道轮架上缠绕管道，联轴器一端安装空心轴上，另一端安装在管道轮架，管道一端安装在空心轴上，另一端通过提引器连接法兰与提引器中心管 相连，在管道外侧安装多节连续的管道护节，使两者形成一体结构，并在管道节驱动轮和管道节调节轮上旋转，并通过管道调节油缸调节位置，管道调节油缸一端安装在调节驱动轮支架上，另一端安装在桅杆上，在空心轴上安装有减速机、泵、空压机。
在管道护节上设置有油气管道口，油气管道一端安装在空心轴上，另一端通过提引器连接法兰与提引器中心管道相连。并在管道节驱动轮和管道节调节轮上旋转，并通过管道调节油缸调节位置。
该桩孔清理机构可安装在旋挖钻机、龙门钻机、其它机动车辆及冲击锤上。
该桩孔清理机构的有益效果是：
该钻机结合旋挖钻机与反循环钻机的优势，利用旋挖钻机的大扭矩、成孔效率高和反循环钻机成孔时的排渣效率高等优势结合而成。增加了钻机的施工孔径，增加了施工速度，降低了能耗，减少了生产成本，更加有利于环境保护。桩孔清理机构也可安装在旋挖钻机上。有效的完成成孔后泥渣清理。

当施工到一定深度，发现提升钻杆4和钻头51耗时加大时，通过设置在钻杆4内部的管道60与提引器30内部的中心管道44连接，并与连接在桩孔清理机构13中的管路15连接，改变旋挖钻机工作模式，形成反循环钻机工作模式。在减速机33的带动下使桩孔清理机构13沿着空心轴14转动，使管路15随着钻杆4向下运动，通过加压油缸6加压，动力头7转动，带动钻杆4和钻头56旋转取土，利用桩孔清理机构13中的泵34抽取钻机的刻取物沿着管路15向上提升，通过空心轴14排入至泥浆池中。也可以用空压机70产生高压气体，高压气体通过油气管道61输送到设置在钻杆4内部的管道60中，带动渣土沿着管道15通过空心轴14排入至泥浆池中。形成气举反循环的工作状态。
通过驾驶员来控制步履行走装置12。来调节移动支脚23和固定支脚24与地面受力情况的交替运行。通过控制纵向行走油缸58的伸缩达到钻机的前后行走和左右转向。在钻机作业时，可使移动支脚23与固定支脚24同时与地面接触受力，以达到钻机的最佳平稳性。
在主车体62中安装有装车油缸10，以便于钻机的装卸和维修。
在主车体62中设置有行走伸缩滑道20，调节行走伸缩滑道20可增加钻机 的横向宽度，根据实际孔径大小来调节步履宽度，增加了钻机的平稳性和安全性。
如图12所示：该装置为链板式送机27，包括：链板输送机伸缩支架25一端安装在链板输送机27上，另一端安装在链板输送机行走支架11上，链板输送机行走支架11上安装有驱动马达40、承重轮41、承重轮支架43，链板输送机行走支架11在钢丝绳51的带动下沿着轨道37前后滑动，轨道37安装在移动支脚24上，链板输送机伸缩支架25在驱动装置31的作用，在钢丝绳51的带动下沿着轨道37前后运动，在链板输送机伸缩支架25安装有导溜板38并通过调节油缸28调节，形成导溜板升起状态57，链板输送机27中安装有驱动装置52、驱动轮53、前导向轮54、导向轴55、链板64。
钻机工作时，链板输送机27在驱动装置31和钢丝绳51的带动下向后运动，至不影响钻机钻头56上下位置时停止，到钻机钻取完成并提取至链板输送机27上方后，链板输送机27在驱动装置31和钢丝绳51带动下向前运动，至钻头56正下方后停止，钻头56内的钻取物卸至链板输送机27后，在驱动装置31和钢丝绳51的带动下向后运动至合适位置停止，在驱动装置52的作用下，使链板输送机27工作，把钻机的钻取物输送出去。
钻头56卸载钻取物时，如果钻取物超出链板输送机27的链板位置时，通过调节油缸28调节导溜板38高度，使钻取物沿着导溜板38导溜至链板输送机27上输送出去。
如图13所示：该装置为提引器30，包括：提引器30内部设置有中心管道44、外花键压板45、双钢丝绳锁扣46、链接法兰49和油气管道61。
