具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
申请概述
为了解决背景技术中存在的吊具受限于回转空间和垂直空间的技术问题，可以采用利用叉车叉刀直接举升集装箱，但是通常情况下，只能完成空箱操作或者轻载状况。或者，利用简单的抓手抓举，以从顶部举升集装箱，但是如果不具备旋转调节和侧移重心调节功能，就会降低集装箱的吊运效率低下。
针对上述的技术问题，本申请的基本构思是提出一种吊具和起吊设备。将吊具拆分为两层：第一层用于吊臂梁可绕回转中心回转，能够减少回转空间；第二层用于吊臂梁可水平调节位置，以能够实现平衡吊运物体。由于连接架与安装架之间的夹角为钝角，且吊梁臂位于夹角处，使得吊臂梁在回转的过程中位于支架的下方，减少了回转空间的占用，提高了吊具对回转空间的环境的适应性。
需要说明的是，本申请所提供的吊具可以应用于任何场景下的起吊设备，尤其是大型起吊设备。具体而言，机械结构的设计目的是要完成具体的工作任务，完成工作任务的方式为通过对应的机械结构或机械结构中的部分或全部组件以完成具体的机械动作或信息传递。
在介绍了本申请的基本原理之后，下面将参考附图来具体介绍本申请的各种非限制性实施例。
示例性吊具
图1所示为本申请一些实现方式提供的吊具的侧视结构示意图。如图1所示，该吊具用于起吊设备，该吊具包括：支架110、回转支撑机构120、回转驱动装置130和吊臂梁140。
具体地，支架110包括连接架111和安装架113，安装架113设于连接架111的一端，连接架111的一端可用于与吊装设备进行连接，且连接架111的另一端与安装架113的一端连接，或者，连接架111与安装架113一体成型。连接架111与安装架113之间形成的夹角为钝角，可以理解为，连接架111可以形成对安装架113的支撑。回转支撑机构120转动连接于安装架113上，且回转支撑机构120具有一个回转中心，回转驱动装置130与回转支撑机构120连接，回转驱动装置130构造为驱动回转支撑机构120围绕回转中心转动。吊臂梁140与回转支撑机构120连接，使得吊臂梁140可以围绕回转中心回转，且吊臂梁140位于夹角处，减少了空间的占用。吊臂梁140构造为吊装物体。
该吊具，安装架113设于连接架111的一端，能够在连接架111与安装架113之间的下方形成回转空间，从而可节省吊臂梁140的安装空间，从而使得吊具能够适用于较小的空间进行吊运，提高了吊具对工作环境的适应性，且能够提高支架的结构稳定性。回转支撑机构120与安装架113转动连接，且形成一个回转中心，避免了回转驱动装置130在驱动回转支撑机构120转动的过程中相互发生碰撞，提高了吊具使用过程中的可靠性。
继续结合图1所示，在一种可能的实现方式中，回转支撑机构120包括：回转部121和回转台123，回转部121包括固定部和转动部，转动部与固定部可转动连接，使得转动部围绕通孔1131的中心转动，其中，转动部与固定部之间可设置滚珠或滚柱，能够减少固定部与转动部之间的摩擦，且能够减少或者杜绝转动部在回转过程中发生卡止的可能性，这就提高了吊具的可靠性。回转台123与所述转动部连接，吊臂梁140连接于回转台123。其中， 回转部121可以为轴承，固定部为轴承的外圈，转动部为轴承的内圈，回转台123与轴承的内圈连接。
图2所示为本申请一些实现方式提供的起吊设备的局部主视结构示意图。如图所示2，回转台123的外轮廓的尺寸从上到下逐渐增大，使得回转台123的结构更稳定。图3所示为图2所示的实现方式提供的起吊设备的局部俯视结构示意图。结合图2和图3所示，回转台123具有水平贯通的安装槽，吊臂梁140贯穿安装槽并与回转台123连接，使得吊臂梁140部分地包覆于回转台123内，安装槽对吊臂梁140起到限位的作用。继续结合图3所示，安装架113具有上、下贯通的通孔1131，固定部与通孔1131的内侧壁连接。使得回转支撑机构120可以不突出于安装架113，其中，回转支撑机构120与通孔1131的连接方式为直接刚性连接，使得回转支承机构部分地镶嵌在安装架113的内部，从而不占用额外的安装空间。
继续结合图2和图3所示，在一种可能的实现方式中，吊臂梁140的顶面设有顶部轨道165，安装槽的顶部设有缓冲块167，缓冲块167与顶部轨道165相互间隔并上、下相对设置，使得回转台123与吊臂梁140之间存在有缓冲空间，可以防止叉车举升油缸对吊具的硬冲击作用，从而保护吊具。
其中，顶部导轨165也可以设置为两个，两个顶部导轨165相互间隔设于吊臂梁140的顶面上，与此对应地，缓冲块167也相互间隔设置为两个，并分别一一对应与两个顶部导轨165相互配合，当叉车举升油缸对吊具进行举升动作，稳定后，缓冲块167再与顶部导轨165配合滑动，从而起到了缓冲的作用。
继续结合图3所示，在一种可能的实现方式中，吊具还包括：侧移驱动装置150和滑动机构160。其中，侧移驱动装置150与吊臂梁140连接，以能够驱动吊臂梁140横向移动，从而可以调节吊臂梁140的相对两侧吊装的集装箱保持平衡。滑动机构160设于吊臂梁140和回转台123上，使得吊臂 梁140可以与回转台123滑动连接，其中，侧移驱动装置150驱动吊臂梁140通过滑动机构160沿滑动方向滑动，以保证吊臂梁140的位置的调节。
吊具还可以包括控制器，控制器与回转驱动装置130通讯连接，通过控制器发出控制回转驱动装置130发生回转的指令。控制器与侧移驱动装置150通讯连接，通过控制器发出控制侧移驱动装置150发生侧移的指令。控制器与侧移驱动装置150和回转驱动装置130分别通讯连接，通过控制器可同时控制吊臂梁140的回转与侧向移动。
继续结合图3所示，在一种可能的实现方式中，滑动机构160包括：导轨组件和滑块组件，可以理解为，导轨组件包括多个导轨，滑块组件包括多个滑块163，导轨组件沿滑动方向设于吊臂梁140上，滑块组件设于所述安装槽内，且滑块组件与回转台123连接，滑块163构造为支撑导轨并沿导轨滑动。多个导轨与多个滑块163配合，可以保证吊臂梁140的结构稳定性。
继续结合图2和图3所示，在一种可能的实现方式中，导轨组件包括：底部导轨和侧导轨161。其中，滑块组件包括多个滑块163，分别设于安装槽的相对两内侧壁上，多个滑块163分别与底部导轨和侧导轨161和配合滑动连接。其中，导轨组件包括底部导轨，底部导轨设于吊臂梁140的底部，底部导轨可相互间隔设置为两个，与此对应地，安装槽的内侧的槽壁的下端设有滑块163，滑块163支撑于底部导轨上，起到对吊臂梁140的支撑作用。导轨组件还包括侧导轨161，侧导轨161设于吊臂梁140的相对两侧，每侧可设置两个侧导轨161，与此对应地，安装槽的内侧的槽壁上设有与侧导轨161滑动的滑块163，滑块163与侧导轨161相互配合，还能够起到对吊臂梁140的抗扭矩的作用。
继续结合图3所示，在一种可能的实现方式中，侧移驱动装置150包括：侧移固定座151、侧移连接座155和侧移驱动机构153，其中，图5所示为图2所示的实现方式提供的起吊设备的立体结构示意图。
其中，侧移固定座151可设于回转台123上，使得侧移驱动机构153与回转台123连接，以能够减少侧移驱动机构153在驱动吊臂梁140平移的过程中对安装架113产生扭矩。
或者，侧移固定座151也可以设于安装架113上，方便安装侧移固定座151。侧移连接座155设于吊臂梁140上，侧移驱动机构153包括侧移安装部和侧移伸缩部，侧移安装部与侧移固定座151连接，侧移伸缩部与侧移连接座155连接，使得侧移伸缩部通过伸缩可以带动吊臂梁140左右移动位置。其中，侧移驱动机构153可以为油缸。
或者，如图3所示，侧移固定座151设于吊臂梁140上，侧移连接座155设于所述回转台123或安装架113上；以及侧移驱动机构153包括侧移安装部和侧移伸缩部，侧移安装部与侧移固定座151连接，侧移伸缩部与侧移连接座155连接。
继续结合图3所示，在一种可能的实现方式中，回转驱动装置130包括：回转固定座131、回转连接座135和回转驱动机构133，回转固定座131设于安装架113上，使得回转驱动机构133与安装架113连接，回转连接座135设于回转支撑机构120上，以方便驱动回转支撑机构120转动。回转驱动机构133包括回转安装部和回转伸缩部，回转安装部与回转固定座131连接，回转与回转支撑机构120连接，使得回转伸缩部通过伸缩可以驱动回转支撑机构120在正向转动和逆向转动之间进行切换。
继续结合图2和图3所示，在一种可能的实现方式中，吊臂梁140包括：横梁141和至少两个抓具143，横梁141具有相对的两端，至少两个抓具143分别设于横梁141的相对的两端，抓具143可以用于抓取集装箱。更为具体地，横梁141为大梁，抓具143为小梁。横梁141的相对两端分别设有一个抓具143。
示例性起吊设备
图4所示为图2所示的实现方式提供的起吊设备的局部侧视结构示意图。 结合图4和图5所示，该起吊设备10包括：门架200和任一实现方式中的吊具100。其中，吊具100的连接架111与门架200滑动连接，以使得吊具200上升或下降。起吊设备10可以为叉车，叉车的门架200与吊具100配合使用联接为整体，效率更高。
具体地，叉车可以为重型叉车。吊具100的接口与门架200连接，也就是，支架110连接于门架200。其连接方式可以是直接连接也可以是通过可侧移标注叉架连接。支架110在连接后可在门架200的轨道至少上下运动，但不仅限于能上下运动。
回转支承机构120隐藏地连接于支架110，连接方式为直接刚性连接。所述隐藏连接方式即回转支承机构120的回转部121的整体结构镶嵌在连接架113的内部，从而不占用额外的安装空间。
回转台一方面与回转部连接从而本身可以围绕回转中心进行旋转，回转台内设置有滑块，从而允许滑块连接于吊具的大梁上设置有滑轨，滑轨与回转台上的滑块连接，从而允许吊具大梁连同两侧小梁一起相对旋转台产生相对运动。
该起吊设备10，通过吊具100和叉车的接口连接，可以达到利用叉车实现正面吊式起重机的功能，从而降低用户的使用成本，提高效率，减少设备的特殊需求。
另外，本申请中的搬运设备10，由于包括上述任一实现方式中的吊具100，因此具有了上述任一项的吊具100的技术效果，在此不再赘述。
以上仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换等，均应包含在本申请的保护范围之内。
