下面结合图1至图6对本申请实施例提供的一种臂架滑块组件700、臂架总成及作业机械进行描述。应当理解的是，以下所述仅是本申请的示意性实施方式，并不对本申请构成任何特别限定。
本申请第一方面的实施例提供了一种臂架滑块组件700，如图1至图6所示，该臂架滑块组件700包括：
固定座100，固定座100的一端设置有固定头101，固定座100的另一端设置有螺纹段102，螺纹段102用于与臂头200紧固连接，固定头101与螺纹段102之间设置有卡置台103，固定头101与卡置台103之间形成卡槽104；
滑块本体300，滑块本体300穿过固定座100并与臂头200贴合；
挡板400，挡板400穿过固定头101卡置于卡槽104内；
锁止件500，锁止件500安装至挡板400的外侧，以使挡板400与固定座100锁止连接。
在本申请提供的臂架滑块组件700中，固定座100的一端设置有螺纹段102。固定座100的另一端设置有固定头101。固定头101与螺纹段102之间设置有卡置台103。卡置台103与固定头101之间形成用于卡置挡板400的卡槽104。固定座100通过螺纹段102与臂头200螺纹连接。滑块本体300上设置有安装孔303。安装孔303穿过固定头101直至滑块本体300与臂头200贴合。且卡置台103及部分螺纹段102位于安装孔303内。卡置台103能够被限位卡置于安装孔303内。通过调节螺纹段102与臂头200之间的旋入深度，能够调节卡槽104与臂头200之间的间距，进而，使得挡板400能够穿过固定头101卡置于卡槽104内。锁止件500锁止于固定头101与挡板400之间。由此，使得滑块本体300与臂头200紧固连接。
通过这种结构设置，在固定座100的一端设置螺纹段102，并使固定座100通过螺纹段102与臂头200螺纹连接。当滑块本体300的尺寸不同时，表现为安装孔303的孔深的不同，通过调节螺纹段102与臂头200之间的螺纹连接深度，进而调节臂头200与卡槽104之间的间距，使得卡槽104部分或者全部露在安装 孔303的外侧，以便挡板400能够卡置于卡槽104内，无需更换不同尺寸的固定座100。因此，该臂架滑块组件700的通用性较高。另外，当固定座100出现损坏现象时，仅需将固定座100的螺纹段102旋出并更换固定座100即可，其维修换新操作简便，且成本较低。
此处应当理解的是，臂架滑块组件700可以安装在臂头200的上侧、下侧或者左右两侧。例如，如图1所示，在图示方向中，臂头200的上侧、下侧及左右两侧分别设置有多个臂架滑块组件700。其中，如图2和图3所示，安装在臂头200上侧及下侧的臂架滑块组件700的滑块本体300为与臂节相适配的圆弧形滑块本体300。如图4和图5所示，安装在臂头200左右两侧的臂架滑块组件700的滑块本体300为与臂节相适配的平面形滑块本体300。
在本申请的一个实施例中，固定座100还包括调节垫片600。调节垫片600套设至螺纹段102，并用于限位螺纹段102与臂头200的连接深度。
如图2和图4所示，在臂头200与卡置台103之间安装有调节垫片600，或者说，在螺纹段102上安装调节垫片600。在安装时，将固定座100的螺纹段102旋入至臂头200的螺纹中，直至固定座100的卡置台103和臂头200端面分别压紧至调节垫片600的两侧。例如，可以通过安装不同数量的调节垫片600，以限制螺纹段102旋入臂头200的深度。或者，还可以通过安装不同厚度的调节垫片600，以限制螺纹段102旋入臂头200的深度。通过在螺纹段102安装调节垫片600，并将卡置台103与臂头200分别压紧至调节垫片600的两侧，能够提升固定座100连接稳定性和限位调节可靠性。
在本申请的一个实施例中，滑块本体300包括固定部301。固定部301与臂头200贴合。固定部301上开设有安装孔303。安装孔303与卡置台103相适配。卡置台103延伸并卡置于安装孔303内。
挡板400上开设有安装限位槽。固定座100延伸并限位卡置于安装限位槽内。挡板400上还开设有助拆槽404。
例如，如图2至图5所示，滑块本体300包括固定部301。固定部301用于与臂头200连接。滑块本体300还包括滑块部302。滑块部302与伸缩部的臂节内壁相适配。滑块部302用于安装至伸缩臂的相邻臂节之间。固定部301上开设有安装孔303。安装孔303与卡置台103的尺寸相适配。卡置台103能够延伸并 卡置于安装孔303内。安装孔303能够对卡置台103起到一定的限位作用。挡板400上设有安装限位槽。挡板400与固定座100连接时，固定座100延伸并限位至安装限位槽内。
此外，挡板400上还设置有助拆槽404。例如，助拆槽404包括但是不限于腰型槽或者圆形槽结构。当需要安装卡置或者拆卸挡板400时，可以将手指伸入至助拆槽404内并推动挡板400，或者，还可以将相应的工具伸入至助拆槽404内并推动挡板400。
例如，如图2和图3所示，在本申请的一个实施例中，安装限位槽包括安装槽401与限位槽402。安装槽401与限位槽402连通。安装槽401的直径大于固定头101的直径。限位槽402的直径大于卡槽104的内径。限位槽402的直径小于固定头101的直径。
在安装过程中，首先，使固定头101由安装槽401穿过挡板400。然后，沿着限位槽402的方向拉动挡板400，以使固定头101卡置于限位槽402的外侧。最后，将锁止件500连接至固定头101与挡板400处，以防止固定头101窜动至安装槽401内并与挡板400分离。
又例如，如图4和图5所示，安装限位槽包括限位开口槽403。限位开口槽403的宽度大于卡槽104的内径，限位开口槽403的宽度小于固定头101的直径。
在安装过程中，将卡槽104内径处的杆体部分由限位开口槽403的开口端移动至限位开口槽403内，并使固定头101卡置于限位开口槽403的外侧。然后，使用锁止件500将固定座100锁止于限位开口槽403的内侧。
在本申请的一个实施例中，固定座100的数量至少为一个。固定座100与安装孔303及安装限位槽一一对应设置。例如，在图2和图3所示的实施例中，该臂架滑块组件700包括三个固定座100，滑块本体300的固定部301上对应开设有三个安装孔303，挡板400上对应开设有三个安装限位槽。又例如，在图4和图5所示的实施例中，该臂架滑块组件700包括两个固定座100，滑块本体300的固定部301上对应开设两个安装孔303，挡板400上对应开设有两个安装限位槽。
在本申请的一个实施例中，锁止件500包括锁板501。锁板501跨接至其中一个安装槽401上。锁板501的一端通过第一锁止螺钉502与挡板400连接。锁 板501的另一端通过第二锁止螺钉503与挡板400连接。
在本申请的一个实施例中，锁板501上包括有开口槽504和滑动槽505。第一锁止螺钉502由锁板501的外侧穿过开口槽504并与挡板400连接，第二锁止螺钉503由锁板501的外侧穿过滑动槽505与挡板400连接。
锁止件500还包括锁止销506。开口槽504处开设有锁止孔。锁止销506插装至所述锁止孔内，以防止第一锁止螺钉502由开口槽504滑出。锁板501上还开设有助拆槽404。
例如，如图2至图5所示，锁板501的一端开设有开口槽504，另一端设置有滑动槽505。开口槽504为一端形成有开口的槽体结构。滑动槽505为封闭式槽体结构。开口槽504与滑动槽505的方向相同。第一锁止螺钉502能够沿着开口槽504活动，第二锁止螺钉503能够沿着滑动槽505活动。挡板400的安装槽401两侧分别开设有第一螺纹孔与第二螺纹孔。
在安装过程中，首先将锁板501跨接至安装槽401的外侧，再将第二锁止螺钉503穿过滑动槽505并连接至第二螺纹孔，将第一锁止螺钉502穿过开口槽504并连接至第一螺纹孔。最后将锁止销506插装至开口槽504处的锁止孔内，以防止第一锁止螺钉502脱离开口槽504。
在拆卸过程中，首先将锁止销506由开口槽504的开口处拆卸。再通过助拆槽404向远离第一锁止螺钉502的一侧拉动锁板501，以使第一锁止螺钉502与锁板501分离。随后转动锁板501，以使锁板501向远离安装槽401的一侧转动。此时，再拉动挡板400，使得固定头101移动至安装孔303中。最后向远离固定头101的一侧拉动挡板400，以使挡板400与固定头101分离。
根据以上描述可知，通过这种结构设置，可便于工作人员拆装臂架滑块组件700，极大提升了臂架滑块组件700的拆装效率。
本申请第二方面的实施例提供了一种臂架总成，包括多段臂节和如上所述的臂架滑块组件700。多段臂节依次滑动套设连接。相邻的臂节之间安装有臂架滑块组件700。
进一步，由于该臂架总成包括如上所述的臂架滑块组件700，因此，其同样具备如上所述的各项优势。
本申请第三方面的实施例提供了一种作业机械，包括如上所述的臂架滑块组 件700或者臂架总成。
例如，上述作业机械包括起重机。
此处应当说明的是，上述实施例仅是本申请的一个示意性实施例，并不能对本申请构成任何限定。例如，在本申请的其他实施例中，上述作业机械还可以包括臂架式高空作业机械等。
进一步，由于该作业机械包括如上所述的臂架滑块组件700或者臂架总成，因此，其同样具备如上所述的各项优势。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
