Description

三角锯成槽机
一、所属技术领域
本发明涉及一种成槽机，特别涉及一种地下连续墙三角锯成槽机。 
二、背景技术
目前，建造地下连续墙所使用的成槽机械按其挖槽机理大致可分为：挖斗式，冲去式及回转式三种。挖斗式成槽机是以挖斗一斗一斗的从槽内挖土，冲击式成槽机是利用钻头冲击破碎地基土成槽。回转式成槽机是由潜水电机带动多头钻回转钻进成槽。从以上分析可看出，现在地下连续墙成槽设备都存在效率低，造价高等特点。 
三、发明内容
本发明为了弥补现有技术的不足，提供了一种成槽效率高，造价低的三角锯成槽机。 
本发明是通过如下技术方案实现的： 
一种三角锯成槽机，包括臂杆以及臂杆上的两个摆臂，摆臂上端铰接于臂杆，下端铰接于吸砂管。减速机输出端装有偏心轴，偏心轴与连杆的一端连接，连杆的另一端与吸砂管和进水管的上端连接，吸砂胶管与吸砂管连接，通过吸砂口抽吸成槽泥砂，进水胶管与进水管连接，进水由喷水嘴射击。支撑挖刀的刀架为三角形，挖刀为一定倾斜度的斜形。 
本发明具有以下特点： 
1、减速机、电动机以及所有的活动铰接都在水面以上，无需实行潜水密封，型式更加简单，维修方便，磨损轻微。 
2、刀架为三角形，挖刀为倾斜一定角度的斜形，切削地层土的能力更强。 
3、采用正反两套浆液循环系统，即对成槽浆液既射水又抽吸，大大提高了泥渣置换效率。 
4、采用偏心轴通过连杆驱动挖刀往复运动，型式更加简单，功率更强。 
四、附图说明
下面结合附图对本发明作进一步说明 
附图(1)为本发明的结构示意图。 
附图(2)为减速机及偏心轴的侧视图。 
图中：1、减速机，2、偏心轴，3、连轩，4、摆臂，5、上支撑轴，6、吸砂胶管，7、进水胶管，8、喷水嘴，9、挖刀，10、臂杆，11、吸砂管，12、进水管，13、提升滑轮，14、吸砂口，15、刀架，16、电动机。 
五、具体实施方式：
附图为本发明的一种具体实施例，下面通过附图对本发明具体讲述。 
一种三角锯成槽机，包括臂杆10以及臂杆上的两个摆臂4，摆臂上端铰接于臂杆，下端铰接于吸砂管11。减速机输出端装有偏心轴2，偏心轴与连杆3的一端连接，连杆的另一端与吸砂管11和进水管12 的上端连接。吸吵胶管6与吸吵管11连接，通过吸砂口14抽吸成槽泥砂，进水胶管7与进水管12连接，进水由喷水嘴8射出。支撑挖刀9的刀架15为三角形，挖刀9为一定倾斜度的斜形。 
本成槽机在使用过程中需与行走底盘，高压泥浆泵以及抽吸砂泵配合使用。行走底盘上有一提升卷扬机，通过成槽机下部提升滑轮13，升降成槽机下部。成槽机上部通过上支撑轴5，支撑在行走底盘上。行走底盘前端有一牵引卷扬机，通过前面设置的地锚，油丝绳，牵引成槽机前进。 
成槽机成槽超始，应首先启动高压泥浆泵，使高压射水从喷水嘴喷出，然后启动减速机电机，慢速松放行走底盘上的提升卷扬机的抱闸，靠刀具的自重，将成槽机吸砂管及进水管下端沉入予定深度，即成槽的深度。其后，开启牵引卷扬机，通过地锚油丝绳，按一定的速度牵引成槽机前进。成槽机前进过程中，往复运动的挖刀切削土层成槽，成槽机后面，便开出一道一定深度的连续的槽。 
连续的槽浇筑混凝土时要下放隔离体，将连续的槽隔离成一定长度的槽段，浇筑混凝土后便成为地下连续墙。 
本发明是建造地下连续的专用机具。
