具体实施方式
下面结合附图和实施例对本发明的实施方式作进一步详细描述。以下实施例用于说明本发明,但不能用来限制本发明的范围。
在本发明实施例的描述中,术语“第一”、“第二”、“第三”仅用于描述目的,而不能理解为指示或暗示相对重要性。
在本发明实施例的描述中,需要说明的是,除非另有明确的规定和限定,术语“相连”、“连接”应做广义理解,例如,可以是固定连接,也可以是可拆卸连接,或一体连接;可以是机械连接,也可以是电连接;可以是直接相连,也可以通过中间媒介间接相连。对于本领域的普通技术人员而言,可以具体情况理解上述术语在本发明实施例中的具体含义。
在本发明实施例中,除非另有明确的规定和限定,第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触,或第一和第二特征通过中间媒介间接接触。而且,第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方,或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方,或仅仅表示第一特征水平高度小于第二特征。
在本说明书的描述中,参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明实施例的至少一个实施例或示例中。在本说明书中,对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且,描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外,在不相互矛盾的情况下,本领域的技术人员可以将本说明书中描述的不同实施例或 示例以及不同实施例或示例的特征进行合和组合。
值得一提的是,本发明实施例仅仅以高空攀爬运输作业技术领域当中的联动操作组件为例进行说明,不失一般性,本发明实施例的联动操作组件还适用于其他场合,只要满足轨道上多个轮体组件(例如第二轮体组件和第三轮体组件)的联动操作即可。并且,对应不同场合联动操作组件的固定主体的具体结构形式不同。
根据本发明的实施例,请参见图1至图9,联动操作组件包括固定主体5、第二轮体组件01和第三轮体组件02。其中,固定主体5用于安装至轨道006的外支撑面00603,并沿着所述外支撑面00603移动;第二轮体组件01安装于所述固定主体5,用于沿着轨道006的内支撑面00604滚动,所述第二轮体组件01包括第二轮对,所述第二轮对连接主旋转轴0102。第三轮体组件02安装于所述固定主体5,用于沿着轨道006的内支撑面00604滚动,所述第三轮体组件02包括第三轮对,所述第三轮对连接从旋转轴0201。所述主旋转轴0102和所述从旋转轴0201之间设置有联动件。
由此,本发明实施例的联动操作组件,当主旋转轴0102转动的时候,带动第二轮对整体发生转动。一旦主旋转轴0102转动,将通过联动件带动从旋转轴0201转动,进而带动第三轮对转动。由此,在联动操作组件的安装过程当中,只需要主旋转轴0102转动,就可以使得联动操作组件由图1的状态变化成图3的状态,以方便联动操作组件的安装。同样的,当拆卸联动操作组件的时候,也只需要主旋转轴0102转动即可。
在一个实施例中,主旋转轴0102连接主旋件0103,进而旋转主旋件0103的时候,主旋件0103会带动主旋转轴0102转动。其中,主旋件0103可以为旋钮,进而通过旋转旋钮即可切换联动操作组件的状态以快速实现联动操作组件的拆装。当然,主旋转轴0102除了通过主旋件0103驱动,也可以通过其他结构驱动。
需要说明的是,虽然附图中只给出了第三轮体组件02为一个的情形,也即从旋转轴0201为一根的情形,但是很显然第三轮体组件02的数量不受此处举例的限制,进而从旋转轴0201的数量不受限制。
请参见图1至图9,所述主旋件0103通过第一连接件0104连接所述 主旋转轴0102。
请参见图1至图9,所述联动件为联动板03,所述主旋转轴0102通过第二连接件0105连接于所述联动板03,所述从旋转轴0201通过第三连接件0202连接所述联动板03。
请参见图1、图3和图9,所述联动板03上设置有呈L型的锁止孔0302,所述锁止孔0302包括横向孔段和与横向孔段连通的纵向孔段,所述固定主体5上设置有可以沿着所述横向孔段运动的第四连接件0403,所述第四连接件0403位于所述横向孔段时所述联动板03被锁止,所述第四连接件0403位于所述纵向孔段时所述联动板03可纵向运动。
根据本发明的实施例,联动操作组件包括解锁组件04,解锁组件04包括上述第四连接件0403,还包括滑动轴0401和第六弹簧0402,第四连接件0403穿过固定主体5上的滑动孔0602连接到滑动轴0401,通过按压滑动轴0401可以压缩第六弹簧0402,使得第四连接件0403运动至锁止孔0302的纵向孔段,此时旋转主旋件0103可以带动联动板03升降。而当第四连接件0403位于锁止孔0302的横向孔段时,此时联动板03无法升降,进而无法转动主旋件0103。
其中为了便于按压滑动轴0401以调节第四连接件0403在锁止孔0302中的位置,滑动轴0401至少部分外露于所述滑动孔0602。
在一个实施例中,所述固定主体5上设置有所述联动板03的导向限位轮08,所述导向限位轮08用于限制所述联动板03横向运动并使得所述联动板03沿着纵向运动。
其中,“导向限位轮08用于限制所述联动板03横向运动并使得所述联动板03沿着纵向运动”当中的纵向指代的是轨道006的延伸方向,横向也即轨道006的宽度方向,也即垂直于纵向的方向。主旋件0103带动主旋转轴0102转动的时候,第二连接件0105也发生转动。而由于联动板03只沿着纵向运动,由此第二连接件0105带动联动板03纵向运动的同时,必然相对联动板03横向运动。由此可知,在联动板03上形成有沿着横向延伸的主动孔0303,第二连接件0105一端安装于主旋转轴0102,另一端位于主动孔0303中通过主动孔0303连接联动板03。同样的道理,联动板03上形成有沿着横向延伸的从动孔0301,第三连接件0202通过从动孔 0301连接联动板03。
通过图1、图3、图6、图7和图9发现,导向限位轮08的数量为四个,且通过固定螺钉07安装于固定主体5,联动板03形成有导向面0304,进而通过导向限位轮08和导向面0304之间的配合,保证联动板03沿着纵向运动。当然,导向限位轮08并非是必须结构,并且在设置有导向限位轮08的情况下,其数量和分布位置也可以根据需要进行调整。
根据本发明实施例的联动操作组件,包括限位机构,限位机构用于限制主旋转轴0102在两个极限位置之间转动,在其中一个极限位置主旋转轴0102纵向设置,在另外一个极限位置主旋转轴0102横向设置。此处的“纵向”和“横向”同样分别指代轨道006的延伸方向以及轨道006的宽度方向。其中,当主旋转轴0102纵向设置的时候,此时联动操作组件的形态请参见图3,此时可以方便联动操作组件的拆装。当主旋转轴0102横向设置的时候,此时联动操作组件的形态请参见图1,此时可以将联动操作组件固定在轨道006上,防止联动操作组件从轨道006脱离。
请参见图9,根据本发明实施例的联动操作组件,其还包括联动板03的盖板05,盖板05上设置有限位孔,第二连接件0105在限位孔转动。其中,限位孔和第二连接件0105之间组成上述限位机构。
在一个实施例中,限位孔被构造为:主旋转轴0102转动到极限位置时,第二连接件0105在与限位孔的内壁限位配合,并且中转动至两个极限位置时,主旋转轴0102转动角度不大于九十度。
当然,限位机构除了采用限位孔和第二连接件0105的结构形式,还可以采用其它结构形式,只要满足对主旋转轴0102的限位需求即可。例如,第二轮体组件01还包括滑块0101,滑块0101固定于主旋转轴0102,且滑块0101形成有第二轮对的安装槽;限位机构包括滑块0101以及形成于固定主体5的凸起;主旋转轴0102转动至极限位置,滑块0101与固定主体5上的凸起限位配合。图4至图7中,联动操作组件在两种形态之间切换时,主旋转轴0102转动角度刚好为九十度。当然,如果主旋转轴0102转动角度小于九十度的时候,也能够满足联动操作组件的拆装需求,那么也可以限定主旋转轴0102转动角度为更小的值。
图9中,限位孔包括第三限位面0501和第四限位面0502,进而当旋 转主旋件0103的时候,主旋转轴0102带动第二连接件0105在限位孔中转动,转动至第一个极限位置的时候,第二连接件0105和第三限位面0501接触,转动至第二个极限位置的时候,第二连接件0105和第四限位面0502接触。通过第二连接件0105与第三限位面0501和第四限位面0502之间的配合,保证联动操作组件只能在图4和图5两种形态之间切换。
请参见图6至图9,所述固定主体5上设置有第一定位槽0601,所述第一定位槽0601中设置有滑动销09,所述主旋转轴0102设置有第二定位槽01021和第三定位槽01022。所述联动操作组件倒装于所述轨道006,且所述主旋转轴0102转动至其中一个所述极限位置时:所述第一定位槽0601和所述第二定位槽01021对应,使得所述滑动销09部分进入所述第二定位槽01021;所述联动操作组件倒装于所述轨道006,且所述主旋转轴0102转动至另外一个所述极限位置时,所述第一定位槽0601和所述第三定位槽01022对应,使得所述滑动销09部分进入所述第三定位槽01022。
当联动操作组件正常安装的时候,此时滑动销09在重力作用下位于固定主体5的第一定位槽0601当中,此时滑动销09和主旋转轴0102之间没有连接关系,进而不会干涉主旋转轴0102的运动。当联动操作组件倒置的时候,请参见图6和图7,在两种不同形态下,第一定位槽0601分别对应主转轴上的第二定位槽01021和第三定位槽01022,进而滑动销09在重力作用下部分进入第二定位槽01021或者第三定位槽01022当中,此时滑动销09可以阻止主旋转轴0102转动,进而使得联动操作组件无法实现安装。
请参见图2、图8和图9,根据本发明实施例的联动操作组件,在固定主体5设置有从动定位孔0603和主动定位孔0604。具有复位功能的第五弹簧0106用于安装在固定主体5和主旋转轴0102之间,以及用于安装在固定主体5和从旋转轴0201之间。对于第二轮体组件01而言,第五弹簧0106一端安装到主旋转轴0102上的第一复位孔01023内,另一端安装到固定主体5上的主动定位孔0604内并将主旋转轴0102安装到固定主体5上。对于第三轮体组件而言,第五弹簧0106一端安装到从旋转轴0201上的第二复位孔02011内,另一端安装到固定主体5上的从动定位孔0603内并将从旋转轴0201安装到固定主体5上。当然,此处的第五弹簧0106 也可以通过其它具有复位功能的复位件替代。
对于第二轮体组件01,滑块0101通过安装轴0108安装到主旋转轴0102上,滚轮0107和定位垫片0109安装到安装轴0108上。对于第三轮体组件而言,滑块0101通过安装轴0108安装到从旋转轴0201上,滚轮0107和定位垫片0109安装到安装轴0108上。
上述提及的第一连接件、第二连接件、第三连接件和第四连接件均可以采用销子的结构形式。

本发明实施例的防坠落装置,具有上述联动操作组件,因此可以实现快速拆装。
根据本发明实施例的防坠落装置,还包括锁止件和第一触发机构1。其中,上文提及的联动操作组件中的固定主体5与锁止件和第一触发机构1组成防坠落锁紧组件。
参见图10至图15,根据本发明实施例的防坠落锁紧组件,包括固定主体5、锁止件和第一触发机构1。其中,固定主体5,通过含有轮轴106的第一轮体组件安装至轨道006(轨道006的结构请参见图17、图20和图21)的外支撑面00603;锁止件安装于所述固定主体5,且在锁止位置和自由位置之间切换;第一触发机构1安装于所述固定主体5,且第一触发机构1包括传动件和驱动件,所述传动件用于安装至所述轮轴106且随所述轮轴106转动,所述传动件随离心力(传动件随所述轮轴106转动,因此受到离心力作用)变化在第一位置和第二位置切换,在所述第一位置所述传动件与所述驱动件脱离,在所述第二位置所述传动件将所述轮轴106的转动传递给所述驱动件,所述驱动件转动带动所述锁止件运动至所述锁止位置。
根据本发明实施例的防坠落锁紧组件,第一触发机构1的传动件安装于轮轴106,且传动件随着轮轴106转动,进而传动件的转速不同,传动件受到的离心力也不同。当轮轴106的转速超过设定转速,传动件受到离 心力运动至第二位置,并将轮轴106的转动传递给驱动件,驱动件带动锁止件运动至所述锁止位置。由此该种防坠落锁紧组件通过监测轮轴106的转速,实现防坠落装置的自动锁止。例如,当作业人员意外坠落时,轮轴106将会具有较高的转速,进而传动件会在离心力作用下朝着驱动件运动,轮轴106带动驱动件一起运动,由此驱动锁止件运动至锁止位置,保证使用安全性。
请参见图10、图11和图12,本实施例的防坠落锁紧组件,所述传动件为触发块108,多块所述触发块108之间通过第一弹性件(第一弹簧111)连接。在所述第一位置,请参见图11,所述第一弹性件处于原始状态;在所述第二位置,请参见图14,所述第一弹性件被拉伸。所述驱动件为凸轮105,所述触发块108设置在所述凸轮105内,所述触发块108形成有限位部。请参见图14,在所述第二位置所述限位部与所述凸轮105的内表面限位配合,所述锁止件为锁块3,所述锁块3形成有锁块第一触发面302,凸轮105形成有凸轮触发面1051,进而凸轮105通过凸轮触发面1051作用于锁块第一触发面302,带动锁块3转动。请参见图11和图12,锁块3形成有定位面303,进而当锁块3运动至锁止位置的时候,锁块3的定位面303和固定主体5上的第二限位面502(第一限位面501在后文描述第二触发机构2的时候会提及)配合。
在一个实施例中,触发块108的数量为两块,两块触发块108之间的第一弹性件为第一弹簧111。在正常情况下,第一弹簧111处于原始状态,此时第一弹簧111的一端连接其中一块触发块108,另一端连接另外一块触发块108,并且两块触发块108都安装于轮轴106。在轮轴106转速超过设定转速的情况下,受到离心力作用,两块触发块108具有远离轮轴106轴心方向运动的趋势,并使得第一弹簧111被拉伸。触发块108运动到第二位置的时候,触发块108和凸轮105内表面之间形成限位配合,进而轮轴106通过触发块108将运动传递至凸轮105。
在一个实施例中,请参见图11、图12和图16,第一轮对的转轮101通过第一销轴107安装于轮轴106,触发块108通过第二销轴110安装于轮轴106,凸轮105通过支撑板104和滑动安装座102安装到轮轴106上,轮轴106一端的滑动安装座102安装到固定座109上后再安装到固定主体 5的第一安装孔503上,轮轴106另外一端的滑动安装座102安装到固定主体5的第二安装孔504上。
当然,传动件、驱动件和锁止件的具体结构都不受此处举例的限制。例如,传动件也可以为安装于轮轴106的传动轴,当轮轴106的转速大于设定转速的时候,传动轴在离心力作用下朝着驱动件运动,传动轴和驱动件限位配合,进而达到将轮轴106的转动传递给驱动件的目的。又例如,当传动件为触发块108的时候,触发块108的形状和数量也可以不受附图的限制,例如触发块108的数量也可以为三块或者任意多块。此外,驱动件也并非一定要是凸轮105,只要在传动件处于第二位置时,可以跟随轮轴106转动并驱动锁止件运动至锁止位置即可。同样的,锁止件也并非一定要采用锁块3的形式,只要满足在锁止位置和自由位置之间切换,并且运动至锁止位置的时候可以用于将防坠落装置锁紧于轨道006即可。
根据本发明的实施例,请参见图10至图15,防坠落锁紧组件还包括第二触发机构2。第二触发机构2安装于所述固定主体5,包括摆杆20,所述摆杆20在复位位置和受力位置之间切换,在所述复位位置,所述摆杆20驱动所述锁止件运动至所述锁止位置。
具体的,在正常情况下,摆杆20在防坠落锁紧组件的重力作用下直接或者间接吊挂于作业人员身上,此时摆杆20并不对锁止件施加作用力。在失重情况下,作用于摆杆20的重力作用消失,此时摆杆20会向锁止件施加作用力,摆杆20和固定主体5的第一限位面501之间形成限位配合,摆杆20的触发面203向锁块第二触发面301施加作用,使得锁止件运动至锁止位置。
由此,具有上述第一触发机构1和第二触发机构2的防坠落锁紧组件,两套触发机构独立作用且互不干扰,保证了防坠落装置的安全可靠。
根据本发明的实施例,请参见图11和图13,摆杆20包括触发端(左端)和自由端(右端),所述触发端通过第二弹性件连接所述固定主体5,所述自由端形成有连接孔201,所述连接孔201用于连接缓冲装置0011;所述锁止件为锁块3,所述锁块3上形成有与所述触发端配合的锁块第二触发面301。
此外,在摆杆20的触发端形成有作用面202,进而第二弹性件一端连 接固定主体5,另一端连接作用面202。在正常情况下,摆杆20受到防坠落锁紧组件的重力作用向上抬起摆杆20的自由端,此时作用面202压缩第二弹性件,且触发端和锁块3之间互相独立。当发生意外坠落的时候,此时摆杆20不再受到防坠落锁紧组件的重力作用,进而此时处于压缩状态的第二弹性件会给摆杆20施加力使得摆杆20顺时针转动,并驱动锁块3顺时针转动至锁止位置。
在一个实施例中,第二弹性件为第二弹簧7。当然,本申请中包括第二弹性件在内的所有弹性件,都不局限于采用弹簧的结构形式,还可以采用其他具有形变和复位功能的结构。
请参见图11至图13,锁块3通过第四弹性件连接至固定主体5,第四弹性件可以但是不局限采用第四弹簧6。正常情况下,锁块3通过第四弹簧6连接至固定主体5,第四弹簧6处于原始状态的时候锁块3处于自由位置,此处的自由位置是相对锁止位置而言,也即当锁块3处于自由位置的时候不会影响防坠落装置的运动。锁块3受到上述凸轮105或者摆杆20驱动的情况下,锁块3运动至锁止位置,进而此时锁块3压缩第四弹簧6。
请参见图10、图11和图12,锁块3和摆杆20都通过芯轴4安装到固定主体5上,进而锁块3和摆杆20各自以芯轴4为中心轴进行转动。
在一个实施例中,请参见图12和图15,轮轴106通过滑动安装座102安装于所述固定主体5,所述滑动安装座102通过第三弹性件连接所述固定主体5,所述固定主体5设置有螺纹紧固件,螺纹紧固件用于调节第三弹性件的状态,具体的螺纹紧固件转动时第三弹性件的状态发生变化,进而带动滑动安装座102滑动,滑动安装座102滑动时带动轮轴106相对固定主体5的安装面靠近或者远离。其中,固定主体5的安装面指代的是固定主体5用于朝向外支撑面00603的表面,也即图13和图14中固定主体5的左侧面。其中,轮轴106相对固定主体5的安装面靠近,会使得固定主体5安装至轨道006时轮轴106上的转轮101更加贴紧轨道006的外支撑面00603;轮轴106相对固定主体5的安装面远离,可以保证固定主体5安装至轨道006时轮轴106上的转轮101和轨道006的外支撑面00603之间不互相干涉。
由此,通过调节螺纹紧固件,可以保证轮轴106上的转轮101和轨道006的外支撑面00603之间形成更好的配合,保证转轮101可以沿着外支撑面00603滚动。
根据本发明的一个实施例,螺纹紧固件为调节螺钉8,第三弹性件为具有调节功能的第三弹簧103。调节螺钉8安装到固定主体5上,通过调节螺钉8压缩第三弹簧103调节轮轴106的位置,使得第一轮对的转轮101实时与轨道006接触,第一轮对转动的时候轮轴106转动,带动触发块108转动,一旦触发块108的离心力超过设定值,则触发块108朝着凸轮105运动并和凸轮105的内表面之间形成限位配合,使得轮轴106通过触发块108带动凸轮105转动,凸轮105转动即可带动锁块3运动至锁止位置。由此,保证第一轮对的转轮101与轨道006接触,可以实现监测防坠落装置的运行速度的目的,当防坠落装置滑落速度超过设定值时凸轮105触发锁块3运动至锁止位置,进而将防坠落装置锁止在轨道006上。
根据本发明的实施例,请参见图17至图22,提供一种防坠落系统,包括轨道006以及安装于所述轨道006的防坠落装置。此外,防坠落装置还包括挂钩009和缓冲装置0011。
请参见图17和图20至图22,轨道006包括滑块通道00601、运行限位面00602、外支撑面00603、内支撑面00604和轨道支撑面00605。转动主旋件0103,使得防坠落装置在图18和图19两种状态切换。当防坠落装置处于图19的状态时,此时可以将防坠落装置安装至轨道006,或者可以将防坠落装置从轨道006拆下。当防坠落装置处于图18的状态时,此时防坠落装置可以固定在轨道006中,使得滑块0101位于滑块通道00601当中,并沿着滑块通道00601运行。此外,当防坠落装置安装于轨道006的时候,所述固定主体5上的第五限位面505在运行限位面00602内运行并通过其实现对防坠落装置水平方向的限位。所述防坠落装置运行时,所述外支撑面00603和安装到固定主体5上部的滚轮0107接触,所述内支撑面00604和安装到运行支撑滑块01012上的滚轮0107接触。所述防坠落装置锁止时,所述外支撑面00603和安装到固定主体5下部的滚轮0107接触,所述内支撑面00604和安装到锁止支撑滑块01011上的滚轮0107接触。
通过图19至图22发现,本发明实施例的固定主体5上固定有四对轮体组件,包括上述提及的用于沿着轨道006内支撑面00604滚动的第二轮体组件01和第三轮体组件02,此外还包括用于沿着轨道006外支撑面00603滚动的两对轮体组件,这四对轮体组件分别包括有至少一对滚轮0107。除此此外,在固定主体5上还安装有第一轮体组件,第一轮体组件包括上述转轮101,转轮101实时与外支撑面00603接触,实现对运行速度的监测。所述防坠落装置通过锁块3的锁块支撑面304与轨道006的轨道支撑面00605接触实现对防坠落装置的锁止。
上述防坠落系统,通过第一触发机构1和第二触发机构2使得锁块3触发阻止防坠落装置不正常的相对于轨道006向下运行,并在从触发位置移动到锁止位置的同时与轨道006相互作用,所述缓冲装置0011的一端安装到连接孔201上,一端与挂钩009连接。
以上实施方式仅用于说明本发明,而非对本发明的限制。尽管参照实施例对本发明进行了详细说明,本领域的普通技术人员应当理解,对本发明的技术方案进行各种组合、修改或者等同替换,都不脱离本发明技术方案的精神和范围,均应涵盖在本发明的权利要求范围中。
