为使本发明的上述目的、特征和优点能够更加明显易懂,下面结合附图和具体实施方式对本发明作进一步详细的说明。
实施例一:
参照图1-图3,本实施例提供了一种水下机械手,包括安装盘1,安装盘1连接有用于控制安装盘1升降的升降部以及用于控制安装盘1水平运动的驱动部;安装盘1的一侧固定设置有机械手主体2,机械手主体2 内部滑动连接有若干机械爪3,每个机械爪3均通过控制部控制其旋转。本实施例通过升降部直接控制安装盘1的升降,通过驱动部驱动安装盘1在水中某平面内运动,使机械手可以在特定的范围内随意运动,使其可以长距离运动并减小水上船体或者水下机器人7对其的限制,并通过控制部控制机械爪3在机械手主体2内部滑动,多组机械爪3同步工作可以实现抓取、拖拽等工作,可实现海底大部分的水下作业。
进一步优化方案,升降部包括与安装盘1固定连接的膨胀球体4,膨胀球体4连通有气管5,气管5固定连接有限位缆绳6,气管5和限位缆绳6的端部均与水上船体或者水下机器人7连接。根据实际需要控制气管5和限位缆绳6的长度,进而限制机械手的工作以及运动范围。限位缆绳6为弹性密封结构,且限位缆绳6内部为空心结构,气管5设置在限位缆绳6的内部,减小水下压强对气管5的挤压作用;通过水上船体或者水下机器人7向气管5内充入或者抽出气体,进而控制膨胀球体4的体积,使机械手的整体浮力变大或者变小,机械手的重力大于浮力时,机械手下降或者在水底不动,当浮力大于重力时,机械手向上运动,当限位缆绳6变直时,在限位缆绳6的牵引力的作用下,机械手维持在某一水平高度上。根据机械手的重力控制充入膨胀球体4的气体量,进而控制机械手的整体升降。
进一步优化方案,安装盘1包括固定连接的上固定盘8和下连接盘9,机械手主体2、膨胀球体4均与上固定盘8固定连接,气管5、限位缆绳6均与下连接盘9固定连接。上固定盘8和下连接盘9之间通过固定杆连接。上固定盘8和下连接盘9之间转动连接有旋转轴10,旋转轴10的中部为空心结构,固定杆设置在旋转轴10的内部,且旋转轴10可以绕固定杆旋转。驱动部包括驱动轴11以及固定设置在驱动轴11上的螺旋桨12,驱动轴11贯穿旋转轴10且与上固定盘8平行设置,驱动轴11通过第一电机驱动。旋转轴10通过第二电机直接驱动,从而控制驱动轴11和螺旋桨12的方向,并通过第一电机控制驱动轴11旋转使螺旋桨12正常工作,在螺旋桨12的作用下,实现机械手的水平运动,在该过程中,由于浮力的作用,机械手的行进轨迹为弧线结构。同时在第二电机的作用下,可以轻松实现转向工作。同时,当海底以及水底存在水流时,可以通过螺旋桨 12的微旋转,抵消掉水流的影响,保证机械手可以稳定的呆在某一位置。
进一步优化方案,机械手主体2和安装盘1之间固定设置有与机械爪3数量相同的连接套筒13,控制部包括设置在连接套筒13内的旋转杆14,旋转杆14的一端通过锥齿轮组件连接有传动轴15,传动轴15与旋转杆14垂直布置,机械爪3的外侧设置有轮齿,连接套筒13内部转动连接有与轮齿相适配的驱动齿轮19,驱动齿轮19与传动轴15轴接。上固定盘8内部设置有驱动电机以及齿轮组件,根据需要设定两者的数量,通过驱动电机以及齿轮组件驱动旋转杆14的旋转,进而带动传动轴15的旋转,从而带动驱动齿轮19驱动机械爪3旋转,实现机械爪3在机械手主体2内部滑动,实现抓取工作,同时可以驱动第一电机工作,使机械爪开始运动,从而实现拖拽工作。
机械手主体2为卧式半圆筒结构,机械爪3为与机械手主体2半圆筒结构相适配的圆弧形结构,机械爪3设置有不少于两组且分别布置在机械手主体2内部的两侧,连接套筒13布置在机械手主体2外部两侧。机械手主体2半圆筒的两端可拆卸连接有与半圆筒相适配的端板20,每个端板20的外侧均设置有限位板16,限位板16与安装盘1之间连接有液压缸17。当需要形成密封结构时,机械爪3设置有两组,且机械爪3的长度与机械手主体2的长度相同,合拢后机械爪3与机械手主体2形成圆筒形,并通过限位板16、端板20对圆筒端部进行密封。当机械手抓取的是线缆等近似圆柱形结构式,拆掉两侧的端板20,使合拢后机械爪3与机械手主体2形成的圆筒形可以抓住物件。
进一步优化方案,每个机械爪3与机械手主体2之间均设置有弹性限位网18,弹性限位网18的一端设置在机械爪3的最高端,弹性限位网18的另外一端固定设置在机械手主体2的内部。弹性限位网18会跟随机械爪3的运动而运动,在弹性的作用下,弹性限位网18变长并将物件包裹住,适应不同形状的物件,且可以实现二次固定。
实施例二:
参照图4-图5,本实施例提供一种水下机械手,本实施例与实施例一的区别仅在于,机械手主体2为空心半球形结构,机械爪3为与机械手主体2空心半球形结构相适配的三维弧形结构,本实施例适用于抓取近似与 圆球形结构的物品。
进一步优化方案,机械爪3的三维弧形为三点式结构,机械爪3的第一端点设置在机械爪3的最上部,机械爪3的第二端点和第三端点均设置在最下部且处于同一水平线,其类似于西瓜上的花纹;机械爪3的数量布置有不少于三组,且相邻机械爪3之间的间距相同,通过多组机械爪3实现多方位对物品进行限位。同时,弹性限位网18会跟随机械爪3的运动而运动,在弹性的作用下,弹性限位网18变长并将物件包裹住,适应不同形状的物件,且可以实现二次固定。

以上所述的实施例仅是对本发明的优选方式进行描述,并非对本发明的范围进行限定,在不脱离本发明设计精神的前提下,本领域普通技术人员对本发明的技术方案做出的各种变形和改进,均应落入本发明权利要求书确定的保护范围内。
