底盘 2主要包括车架 21、 驾驶室 22、 配重 23、 动力装置、 传动装置和控 制装置， 驾驶室 22、 配重 23固定在车架 21上， 动力装置在控制装置控制下， 将动力输出至传动装置， 并经传动装置驱动履带行走装置 4。
高架浮箱 3为中空结构， 高架浮箱 3设于底盘 2的底部。
优选方案中， 高架浮箱 3与底盘 2通过回转平台 24连接， 底盘 2可随回 转平台 24在平面内 360。范围内做回转运动。 这种结构可以在履带行走装置 4 不移动的情况下， 调整底盘 2上的工作装置 1的平面位置， 与变幅机构 17配 合， 可以在工作半径以内的 360。的平面范围内任意位置进行打桩施工。 这种 结构与固定式底盘相比， 需要调整作业位置时， 不用移动履带行走装置 4, 可 以避免履带反复碾压地面，从而可以减低地面液化程度，提高打桩设备作业的 安全性。
两组履带行走装置 4分别设置底盘 2底部的两侧， 具体方案中， 两组履带 行走装置 4分别设于高架浮箱 3的下方。
高架浮箱 3与履带行走装置 4之间通过伸缩支腿装置连接，伸缩支腿装置 用于在不同水深工况时调整高架浮箱 3的高度， 即调整底盘 2的高度。
每个履带行走装置 4包括两个并排设置的履带机构 41 , 两个履带机构 41 通过连接机构 42连接， 连接机构 42能够将并排设置的履带机构 41固定连接 在一起， 且连接机构 42的上端面设有可以固定伸缩支腿装置的连接部， 伸缩 支腿装置分别连接高架浮箱 3和连接机构 42。
优选方案中， 伸缩支腿装置为伸缩支腿装置， 进一步的方案中， 伸缩支腿 装置为伸缩油缸 5 , 伸缩油缸 5包括伸缩油缸缸体 51、 活塞杆 52, 伸缩油缸 5 的一端通过法兰与连接机构 42连接， 伸缩油缸 5的另一端通过螺栓与高架浮 箱 3连接。
在一种具体的实施方式中， 伸缩油缸 5的活塞杆 52的端部通过法兰与连 接机构 42连接， 伸缩油缸缸体 52置于高架浮箱 3内， 伸缩油缸缸体 51的端 部通过螺栓与高架浮箱 3的骨架连接。伸缩油缸缸体 51若置于高架浮箱 3夕卜， 由于伸缩油缸 5在不同工况下可能会处于水面以下， 伸缩油缸 5容易被腐蚀， 本发明将伸缩油缸 5置于高架浮箱 3内， 可以保护伸缩油缸， 减小其被腐蚀的 程度； 而且伸缩油缸缸体置于高架浮箱 3内， 可使得整机的结构更加紧凑。
优选方案中，伸缩油缸 5的数量为四个，每个履带行走装置 4与高架浮箱 3之间均通过两个伸缩油缸 5连接， 为了保证高架浮箱 3及底盘 2能处于平衡 状态， 四个伸缩油缸 5对称设置。
可以理解， 只要能保证高架浮箱 3及底盘 2能处于平衡状态，每个履带行 走装置 4与高架浮箱 3之间可以设置一个或多个伸缩油缸，均应在本发明的保 护范围内。
履带行走装置 4的具体结构请参看图 5 , 图 5为图 1中履带行走装置的立 体结构示意图。
如图 5所示， 履带行走装置 4包括两个并排设置的履带机构 41 , 两个履 带机构 41通过连接机构 42连接固定， 连接机构 42用于固定连接两个履带机 构 41 ,且连接机构 42的上端面设有与伸缩油虹 5固定的连接部， 连接机构 42 可与伸缩油缸 5的活塞杆 52通过法兰连接。
履带机构 41如图 6所示， 图 6为图 5中 I部隐藏驱动轮上两块履带主板 后的放大图。 履带机构 41包括浮箱式履带 411、 履带浮箱 412、 驱动轮 413 , 浮箱式履带 411设置于履带浮箱 412的周向，驱动轮 413用于驱动浮箱式履带 411转动， 在所述传动装置的驱动下带动浮箱式履带 411转动。
优选方案中， 动力装置为液压泵， 液压泵通过传动装置输出压力油至液压 马达，将液体的压力能转换为液压马达输出轴输出的旋转形式的机械能， 经减 速箱减速并增大输出扭矩后输出至履带机构 41的驱动轮 413。
其中， 履带浮箱 412的结构如图 7所示， 图 7为图 5中履带浮箱的立体结 构示意图。 履带浮箱 412为中空结构， 当履带式行走装置 4位于水中时， 履带 浮箱 412可提供一定的浮力， 可减小履带行走装置 4的接地比压，有效防止履 带行走装置 4沉陷于地面或水底。 两个履带机构 41的两个履带浮箱 412通过 连接机构 42连接， 将两个履带机构 41连接固定。
优选方案中， 浮箱式履带 411采用间隔式履带板结构， 浮箱式履带主要包 括履带主板 411-1、 履带辅板、 链轨、 导向轮及支重轮等。 履带主板 411-1优 选为方形履带板， 方形履带板接地面积大， 接地比压小。 履带辅板位于浮箱式 履带内部， 用于保护履带浮箱， 可有效防止履带浮箱 412磨损。
以下结合附图介绍本发明提供的两栖桩机的工作原理。
请参看图 8、 图 9、 图 10、 图 11 , 图 8为本发明提供的两栖桩机在软基滩 涂地面工况时的结构示意图； 图 9为本发明提供的两栖桩机在水深小于 1.8m 的浅水位工况时的结构示意图； 图 10为本发明提供的两栖桩机在水深 1.8m ~ 3.0m工况时的结构示意图； 图 11为本发明提供的两栖桩机在水深大于 3.0m 的深水位工况时的结构示意图。
通常情况下， 两栖桩机主要在滩涂软基地面或水深 0.5m ~ 1.8m的浅水位 工作。
如图 8所示， 潮落后， 两栖桩机到达工作地点， 展开桅杆 13 , 操作人员 通过控制装置下达指令给动力装置， 经传动装置输出至变幅机构 17, 打桩前 应用两台经纬仪对打桩机进行垂直度调整，使桅杆 13垂直， 卷扬提升预制桩， 之后进行正常打桩施工， 此时伸缩油缸 5处于缩回状态。
随着施工的进行， 工作区域开始涨潮， 如图 9所示， 当潮水涨至 0.5m ~ 1.8m时， 操作人员通过控制装置控制伸缩油缸 5内的油压， 使得活塞杆 52伸 出， 此时活塞杆 52推动高架浮箱 3及底盘 2上升， 进而避免海浪的冲击， 保 证安全、 稳定地进行打桩工作。
进一步， 当潮水继续上涨， 当潮水上涨至 1.8m ~ 3.0m时， 如图 10所示， 伸缩油缸 5的活塞杆 52继续伸出， 继续提升高架浮箱 3 , 使得底盘 2始终保 持在水面之上， 此时打桩施工停止， 桅杆 13可放置水平以降低重心， 等潮水 下降至 1.8m以下时可再次启动施工。
需要说明的是， 随着潮水的不断上涨， 只有极少数情况下水深会超过 3m, 但是当水深超过 3m时， 若两栖桩机不能及时撤出该深海区时， 海浪的冲击将 严重影响施工设备和人员的安全， 潮水将淹没车身、 损坏物料及设备等。
由于本发明提供的两栖桩机还包括高架浮箱 3 , 可以解决上述技术问题， 如图 11所示， 当潮水涨至 3m以上时， 伸缩油虹 5的活塞杆 52缩回， 打桩施 工停止， 在高架浮箱 3的浮力作用下， 两栖桩机处于漂浮状态， 此时履带行走 装置 4的履带浮箱 412也可提供部分浮力， 可使两栖装置漂浮， 使得底盘 2 位于水面之上， 保证设备和操作人员的安全。
优选的方案中， 为了提高两栖桩机在海浪的冲击下的稳定性， 两栖桩机的 机身上设有锚装置 6, 两栖桩机处于漂浮状态时， 通过锚装置 6与海底固定， 提高两栖桩机的稳定性， 防止两栖桩机发生倾翻。 本发明提供的两栖桩机与现有技术相比， 包括两组履带行走装置， 两组履 带行走装置分别设置于底盘的底部两侧，该两栖桩机通过两组履带行走装置支 撑于地面或水底，每组所述履带行走装置包括两个并排设置的履带机构，且两 个履带机构通过连接机构连接；并排设置的四个履带机构可以有效减小履带行 走装置在滩涂软土地面的回转阻力， 减小对土体的破坏，提高两栖桩机的通过 性； 履带行走装置与地面或水底的接触面积较大，使得该两栖桩机不易发生沉 陷与倾覆， 可实现安全可靠地进行打桩施工； 机动性能更好， 转场更方便， 工 作效率较高； 履带行走装置与底盘底部的高架浮箱通过伸缩支腿装置连接，伸 缩支腿装置用于在不同水深工况时调整高架浮箱的高度，在工作区域开始涨潮 时， 通过伸缩支腿装置调整高架浮箱的高度， 使得底盘始终位于水面以上， 减 小海浪的冲击， 可以保证安全与稳定地继续进行打桩工作或行驶。 同时随车带 有高架浮箱， 可保证水深大于安全水位时的设备安全， 可实现安全、 可靠地在 近海滩涂区 i或打桩施工。
优选方案中， 高架浮箱 3可采用分体式结构， 高架浮箱 3的数量可以有多 个， 优选方案， 高架浮箱 3可以为三个， 具体可以包括左浮箱、 中浮箱及右浮 箱， 相邻的高架浮箱通过连接件固定连接。 这种结构的高架浮箱拆卸迅速， 方 便陆上运输。
在一种具体的实施方式中， 所述中浮箱通过回转平台 24与底盘 2连接， 伸缩支腿装置与所述左浮箱或所述右浮箱连接。
优选方案中， 桅杆 13采用可折叠的折叠式导杆， 使得整车的结构更加紧 优选方案中， 配重 23的前端设有防浪板， 两栖桩机行驶时用于抵御前方 的海浪。
优选方案中， 锤桩机 12可选用柴油锤或液压锤。
优选方案中， 抱桩器 15包括： 导向机构， 用于调节桩身的垂直度； 工作 平台， 用于人工作业； 导向滑轮， 用于减小桩身与所述导向机构之间的摩擦； 伸缩装置， 用于控制所述导向机构的开合。
以上所述仅是本发明的优选实施方式，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， 还可以做出若干改进和润饰， 这些改进和润饰也应视为本发明的保护范围
