Description

一种绞吸式挖泥船 技术领域
本实用新型涉及河道清淤设备技术领域，具体涉及一种绞吸式挖泥船。
背景技术
现有技术已有较多的用于对江河、湖泊、水库及河涌等进行清淤的挖泥船，清淤方式有绞吸式、抽吸式、耙吸式、斗轮式、射吸式等；使用可直接装袋的挖泥船进行清淤时，一般是把淤泥清上来后转送到岸上一个存放点，然后再进行分解、脱水、包装，最后将含水率较低的淤泥送到制砖厂作为制砖原材料或用于填塘固堤。
当土质中含有大量石块，且石块大小不一，整体成纵向分布时，将给疏浚过程带来很多的困难和麻烦：频繁的堵塞耙头，影响泥浆吸入，生产效率极低，且清理困难严重影响有效施工时间。不仅增加船员的工作强度，同时严重影响了船舶的正常施工作业。
因此，就需要对现有的挖泥船进行改进，不仅能够在船体上完成淤泥的固液分离，而且能够对分离后的淤泥固体进行装袋，装袋后直接运至制砖厂即可，无需另外转运到岸上存放点，减轻工人劳动强度，利于土地资源的节约和工作效率的提高。

附图说明
图1为本实用新型的一种实施方式的一种绞吸式挖泥船的结构示意图；
图2为本实用新型的一种实施方式的一种绞吸式挖泥船的俯视结构示意图。
具体实施方式
下面结合说明书附图，对本实用新型进行进一步详细的说明。
如图1和图2所示，一种绞吸式挖泥船，包括船体1、绞轮2、传输装置3、动力装置4、定位固定装置5和清洗装置6。
船体1中间设置有凹槽，船体1中间部位的绞轮2，在船体1中间设置有凹槽，绞轮2设置于船体1中央的凹槽中，绞轮2中间开设有轴孔21，轴孔21中插装有转轴22，转轴22匹配设置于轴座23上，轴座23通过螺栓方式或焊接方式固定安装于船体1上，转轴22两端均连接有齿轮，并与第二动力机组分别相连，绞轮2的数量有两个，两个绞轮2同轴设置、大小相同，且两个绞轮2之间保持空间，空间的宽度与挖泥翻斗24的宽度相同，因此，绞轮2周圈均匀通焊接或螺栓固定安装有挖泥翻斗24，挖泥翻斗24固定连接于两个绞轮2上，挖泥翻斗(24)为等边直角三角形设置，其中一条直角边通过焊接或螺栓固接于两挖泥翻斗24，另一条直角边开口设置，开口设置的挖泥翻斗24的直角边用于挖泥作业，在挖泥翻斗24端部上通过螺栓固定有加强块25；将两个绞轮2中空设置，可以节约大量原料，挖泥翻斗24的挖泥清淤效果更好，且在挖泥翻斗24端部增加加强块25能有效保护挖泥翻斗24，当加强块25因碰触河底硬物而造成损害时，可随时对加强块25进行更换，维修简便且节约大量维修费用，避免因损坏一个翻斗而需对整个绞轮2进行更换。
动力装置4包括第一动力机组41和第二动力机组42，第一动力机组41为柴油发动机组，第一动力机组41驱动螺旋桨转动，第一动力机组41用于给船体1提供动力；第二动力机组42为两组柴油发动机组，两组柴油发动机组分别通过螺栓固定安装于绞轮2两侧，第二动力机组42通过转轴22与绞轮2相连接，转轴22两端均设有齿轮，通过联轴器和减速器分别连接第二动力机组42上，第二动力机组42还通过动力连接件43连接传输装置3上的从动轮装置32，动力连接件(43)包括传动杆431和转向杆432，传动杆431的一端连接第二动力机组42，另一端通过转轮连接转向杆432上，转向杆432与所述从动轮装置32连接，通常情况下，第二动力机组42中的两组柴油发动机组只开通一组进行运作，柴油发动机组驱动绞轮2进行挖泥清淤工作，同时联动带动传送带31进行同步传输运转；安装两组柴油发动机组可以使得绞轮2一直处于工作状态，并使发动机组可能轮换进行工作，避免长时间工作对机器造成的损伤，且第二动力机组42的动力同步驱动绞轮2和传输装置3，节约动力，增加工作效率。
上述中，第一动力机组41和第二动力机组42均与蓄能装置44相连接， 使得第一动力机组41和第二动力机组42没有利用完的动力储存成电能，方便床上的电力使用。
定位固定装置5包括设于船体1船头的第一定位装置51、设于船体1船尾两边的第二定位装置52，第一定位装置51包括配重装置511和第一定位柱512，第一定位柱512为液压支撑柱，贯穿于船体1并使得第一定位柱512延伸于水中，并插入水底泥土中；第二定位装置52包括第二定位柱521和定位绳锚522，第二定位柱521也是液压支撑柱，第二定位柱521也贯穿于船体1并使得第一定位柱512延伸于水中，并插入水底泥土中，上述中，第一定位柱512和两个第二定位柱521呈三角状态，能很好的固定船体1，使得船体1不会晃动，方便作用；当船体1到达指定河道时，放下液压支撑柱，液压支撑柱往下伸出，探到河道底部并插装固定于淤泥中，保持船体1固定平衡后，放出第二定位装置52中的第二定位柱521和/或定位绳锚522，同样第二定位柱521和定位绳锚522可以配合使用也可以单独使用，当挖泥清淤工作开始后，船体1船尾处重量增加，因而通过配重装置511来保持船体1平衡，配重装置511包括一容水装置、安装于容水装置底部的进水口和顶部的出水口和传感器，传感器为水量高度传感器，可以探测容水装置中的水量高度，当船体1船尾重量增加时，向容水装置中进水，当船尾停止工作时，将融水装置中的水量通过出水口排出，从而保证船体1平衡。
清洗装置6设于船体1船头，清洗装置6为高压水枪，枪头对准绞轮2的挖泥翻斗24，当挖泥翻斗24进行工作后，会有淤泥残留于挖泥翻斗24中，从而影响下次的挖泥工作量，通过清洗装置6用来清洗挖泥翻斗24上的淤垢。
本实用新型所提供的一种绞吸式挖泥船，结构简单，通过绞轮使得河道中的硬质淤泥能被翻起，继而将翻斗中铲出的淤泥通过传送带传送至陆地或其他运输船上，节约工作时间，清淤的效果好，提高工作效率，远远优于现行的挖泥船的工作效率，且结构简单，易于维修，挖泥船平衡效果好，工作环境安全。
以上所述仅是本实用新型的优选方式，应当指出，对于本领域普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出若干相似的变形和改进，这些也应视为本实用新型的保护范围之内。
