具体实施方式
下面详细描述本公开的实施例,所述实施例的示例在附图中示出。下面通过参考附图描述的实施例 是示例性的,旨在用于解释本公开,而不能理解为对本公开的限制。
如图1至图20所示,本公开实施例的掘锚机100包括机架1,截割装置2和锚护装置3。
如图1所示,机架1可视为掘锚机100的机身框架,掘锚机100可以包括行走装置、截割装置2、铲板装置4、输送槽装置5等,行走装置、截割装置2、铲板装置4、输送槽装置5均装配在机架1上。
需要说明的是,其中截割装置2和铲板装置4均设于机架1的前端,截割装置2包括截割滚筒21,铲板装置4位于截割滚筒21的下方,输送槽装置5沿着机架1的长度方向(即前后方向)延伸,经由截割滚筒21截割的煤岩可以被铲板装置4汇拢并输送至输送槽装置5的前端进口处,然后经由输送槽装置5可以将煤岩向后输送。
行走装置可以为履带式行走装置,行走装置可以安装在机架1的下方,通过行走装置可以实现掘锚机100的自行移动。
截割装置2可上下摆动地设于机架1,截割装置2适于截割作业。具体地,如图1和图2所示,截割装置2包括截割臂和截割滚筒21,截割臂大体沿着前后方向延伸,截割臂的后端与机架1相连并相对于机架1可上下摆动,截割滚筒21装配在截割臂的前端,使用时,通过驱动截割臂上下摆动即可实现对前方煤壁的截割作业。
锚护装置3包括升降组件31、作业平台32、第一钻架组件33和稳定组件34,升降组件31设于机架1和作业平台32之间,升降组件31适于升降作业平台32,第一钻架组件33和稳定组件34设于作业平台32,第一钻架组件33具有锚护位置和避让位置,在锚护位置,第一钻架组件33位于截割组件上方并适于锚护作业,在避让位置,第一钻架组件33适于避让截割装置2以使截割装置2可进行截割作业,作业平台32可伸缩以切换第一钻架组件33的锚护位置和避让位置,稳定组件34可撑顶在截割装置2和巷道顶板之间以增强第一钻架组件33在锚护作业时的稳定性。
具体地,如图2和图4所示,升降组件31可以安装在机架1上,升降组件31可以包括升降平台和升降油缸,升降平台固定在升降油缸的顶部,通过升降油缸可以驱动升降平台的升降。作业平台32可以固定在升降平台上,通过升降组件31可以实现作业平台32的升降。
需要说明的是,作业平台32可以为矩形平台,作业平台32沿着前后方向延伸,且作业平台32在前后方向上可伸缩。第一钻架组件33可以安装在作业平台32的前端,其中第一钻架组件33用于锚护作业,具体地,当作业平台32向前方伸出时,第一钻架组件33大体位于截割装置2的截割滚筒21的上方位置处,第一钻架组件33可以对靠近迎头处的巷道顶板进行锚护作业,此时,第一钻架组件33即位于锚护位置。
当需要进行截割作业时,可以将作业平台32收缩,第一钻架组件33后撤至截割装置2的截割滚筒21后方,由此,截割装置2可以通过截割臂驱动截割滚筒21上下移动,从而实现截割作业,此时,第一钻架组件33即切换至避让位置,避免了与截割装置2的干涉。
如图2所示,稳定组件34可以安装在作业平台32的前端,且稳定件34可以位于第一钻架组件33的前侧,稳定组件34可以为伸缩油缸,当第一钻架组件33切换至锚护位置时,稳定组件34可以伸展并与截割装置2的顶侧顶压接触,从而起到临时支护作业平台32前端的作用,避免了作业平台32向前悬伸较长的情况,一方面避免了作业平台32容易挠曲变形的问题,另一方面也减轻了第一钻架组件33在锚护作业时振动,起到了稳固结构的作用。
需要说明的是,在其他一些实施例中,稳定组件34也可以与巷道的顶板顶压接触,稳定组件34也可以同时与巷道的顶板和截割装置2顶压接触。在其他一些实施例中,稳定组件34也可以与巷道的侧壁顶压接触,从而可以满足对巷道侧帮的锚护作业。
可以理解的是,在调整第一钻架组件33的避让位置和锚护位置时,可以通过升降组件31和作业平台32协同调整第一钻架组件33的位置,例如,当截割滚筒21下存在异物,截割臂无法摆动至最下方位置时,可以通过升降组件31将作业平台32升顶至与截割滚筒21高度相适配的位置处,然后可以将作业平台32前伸并通过稳定组件34顶压截割装置2。
掘锚机100在掘进时,可以采用平行作业和非平行作业两种作业方式,其中平行作业即为掘进和锚护同时作业的作业方式,作业时,需要将第一钻架组件33后撤至避让位置,此时,截割装置2可以前 方进行截割作业,第一钻架组件33则可以在截割装置2的后方进行锚护作业。平行作业的方式适合条件较好的巷道顶板,此时,巷道迎头和锚护位置之间可以存在一定的空顶距。
非平行作业即为掘进和锚护交替进行,当非平行作业时,首先通过截割滚筒21完成煤壁的截割进刀,然后可以通过截割臂将截割滚筒21摆动至最下方,然后通过升降组件31和作业平台32将第一钻架组件33移动至截割滚筒21上方,从而可以完成锚护作业。非平行作业的方式适合条件较差的巷道顶板,在迎头推进一个进尺后,能够及时的对靠近迎头的巷道顶板进行支护,缩短了迎头处的空顶距,避免了巷道顶板的冒落,提升了掘进作业的安全性。
本公开实施例的掘锚机100,能够实现掘进和锚护的平行作业和非平行作业,针对不同的巷道顶板条件,可以有针对性的选择相应的掘进方式,从而提高了巷道掘进过程的灵活性,有利于保证掘进的安全性和掘进效率。
其次,在非平行作业时,可以对靠近迎头的巷道顶板进行锚护,从而避免了迎头处存在较大空顶距的情况,保障了巷道顶板条件较差情况下的安全掘进。
另外,由于设有稳定组件34,稳定组件34可以在锚护作业时起到有效撑顶,从而保证锚护作业时结构的稳定性。
在一些实施例中,锚护装置3包括第一锚护装置301和第二锚护装置302,第一锚护装置301和第二锚护装置302沿着机架1的宽度方向间隔布置,第一锚护装置301适于对巷道的一侧锚护作业,第二锚护装置302适于对巷道的另一侧锚护作业,且第一锚护装置301和第二锚护装置302在机架1的长度方向上可错位锚护作业。
具体地,如图3和图5所示,锚护装置3可以设有两个,即第一锚护装置301和第二锚护装置302,两个锚护装置3在左右方向(机架1的宽度方向)上并行间隔布置。第一锚护装置301可以设于机架1的左侧,第一锚护装置301主要对巷道左侧的顶板和侧帮进行锚护作业,第二锚护装置302可以设于机架1的右侧,第二锚护装置302主要对巷道右侧的顶板和侧帮进行锚护作业。
第一锚护装置301和第二锚护装置302一方面能够同时对巷道进行锚护作业,从而能够增强锚护效率,另一方面输送槽装置5可以设于第一锚护装置301和第二锚护装置302之间,从而方便了输送槽装置5的安装,避免了设置单个锚护装置3容易在锚护装置3左右移动时与输送槽装置5干涉的情况。
可以理解的是,在其他一些实施例中,锚护装置3可以仅设有一个,此时,锚护装置3可以对巷道的顶板,巷道的两侧侧帮均进行锚护作业。
需要说明的是,如图3所示,第一锚护装置301的第一钻架组件33和第二锚护装置302的第一钻架组件33可以在前后方向上间隔布置(错位布置),从而可以两侧的锚护作业在空间上错开,避免了在同一宽度截面处作业存在作业空间局促的情况,进一步提升了锚护作业的灵活性。
在一些实施例中,第一钻架组件33包括安装座331和锚钻,安装座331设于作业平台32,锚钻设于安装座331,锚钻相对于安装座331在机架1的宽度方向上位置可调,且锚钻相对于安装座331可转动。
具体地,如图5所示,安装座331可以为长方型,安装座331可以通过螺栓等紧固件固定在作业平台32的前端,且安装座331沿着左右方向延伸。锚钻即为锚杆钻机,锚钻可以导向装配在安装座331上,例如,锚钻可以通过导向槽和滑块与安装座331导向装配,由此,锚钻在安装座331上可以左右滑移,从而可以对不同地巷道宽度位置进行锚护。
锚钻可以通过回转驱动与安装座331可转动地相连,由此,锚钻可以在左右方向摆动,从而使得锚钻既可以对巷道顶板进行锚护,也可以对巷道侧帮进行锚护,提升了锚钻使用的灵活性。
在一些实施例中,安装座331包括第一座3311和第二座3312,第一座3311和第二座3312沿着机架1的宽度方向延伸,第一座3311设于机架1,第二座3312设于第一座3311,且第二座3312相对于第一座3311在机架1的宽度方向位置可调,锚钻包括第一锚钻332和第二锚钻333,第一锚钻332和第二锚钻333设于第二座3312,且第一锚钻332和第二锚钻333的至少一者相对于第二座3312在机架1的宽度方向上位置可调。
具体地,如图12至图14所示,第一座3311可以为方筒状,第二座3312为长方体状,第二座3312 配合在第一座3311内并沿着第一座3311的延伸方向可移动,第一座3311内可以有液压伸缩缸,液压伸缩缸可以实现对第一座3311和第二座3312相对位置的驱动。
锚钻可以设有两个,即第一锚钻332和第二锚钻333,第一锚钻332和第二锚钻333均装配在第二座3312上,由此,当第二座3312在左右方向平移时,第一锚钻332和第二锚钻333也会同步平移,从而可以实现第一锚钻332和第二锚钻333在左右方向上位置的调整。
如图13所示,第一锚钻332可以设在第二锚钻333的外侧(即靠近巷道侧帮的一侧),第二锚钻333可以固定在第二座3312的端部,第一锚钻332则可以导向滑移装配在第二座3312上,即第二锚钻333沿着第二座3312的延伸方向位置不可调,第一锚钻332沿着第二座3312的延伸方向位置可调。由此,第二锚钻333主要用于对巷道顶板锚护作业,第一锚钻332则主要对巷道侧帮进行锚护作业。
如图13所示,第二座3312上设有第一钻座3313和第二钻座3314,第一锚钻332可以通过第一钻座3313与第二座3312相连,第二锚钻333可以通过第二钻座3314与第二座3312相连,其中第一钻座3313与第二座3312导向装配,第二座3312和第一钻座3313之间设有钻座驱动器3315,钻座驱动器3315的一端与第二座3312铰接,钻座驱动器3315的另一端与第一钻座3313铰接,由此,通过钻座驱动器3315可以实现对第一锚钻332位置的调整。可以理解的是,在其他一些实施例中,第一锚钻332和第二锚钻333可以均导向装配在第二座3312上。
第一钻座3313和第二钻座3314可以为回转驱动,由此,第一钻座3313和第二钻座3314均可以在左右方向上摆动,从而方便了对锚杆打设方位的调整。
作业过程中,可以通过对应地驱动器调整第二座3312的位置,从而实现对第二锚钻333位置的调整。可以通过对应地驱动器调整第二座3312的位置,然后可以通过钻座驱动器3315调整第一锚钻332的位置,从而实现对第一锚钻332在左右方向位置的调整,提高了对不同宽度巷道的适应性。
在一些实施例中,在机架1的宽度方向上,第一锚钻332位于第二锚钻333的外侧,第二锚钻333设于第二座3312并在机架1的长度方向和/或宽度方向上可转动,第一锚钻332设于第二座3312并相对于第二座3312在机架1的宽度方向上位置可调,且第一锚钻332在机架1的长度方向和/或宽度方向上可转动。
具体地,如图13所示,第一钻座3313可以具有两个转动轴线,两个转动轴线的其中一个沿着前后方向延伸,另一个沿着左右方向延伸,由此,第一锚钻332既可以在左右方向(机架1宽度方向)摆动,也可以在前后方向摆动(机架1长度方向),进一步提高了对锚杆打设方向调整的灵活性,方便了不同倾斜角度的锚护施工作业。
在一些实施例中,在机架1的长度方向上,稳定组件34位于第一钻架组件33的外侧,第二座3312和稳定组件34之间连接有第一遮挡件326,第一遮挡件326适于在第二座3312移动时展开以阻隔煤岩。
具体地,如图15所示,稳定组件34设在第一钻架组件33的前侧,第一遮挡件326可以为一块胶皮,第一遮挡件326的一侧与第二座3312固定相连,第一遮挡件326的另一侧与稳定组件34固定相连,当第二座3312在左右方向上滑移时,第二座3312会将第一遮挡件326拉伸展开,由此,第一遮挡件326会遮挡在第一钻架组件33的前侧,避免了煤岩砸落设备和操作人员的情况,起到了保护作用。
在一些实施例中,稳定组件34包括第一支撑组件341和第二支撑组件342,第一支撑组件341和第二支撑组件342设于作业平台32,第一支撑组件341可向上伸展并适于与巷道顶板撑顶,第二支撑组件342可向下伸展并适于与截割装置2撑顶。
具体地,如图15所示,第一支撑组件341和第二支撑组件342均可以通过螺栓等紧固件可拆卸地安装在作业平台32的前端。第一支撑组件341和第二支撑组件342可以均为液压伸缩缸,其中第一支撑组件341可以向上方伸展并与巷道顶板撑顶,第二支撑组件342可以向下方向伸展并与截割装置2撑顶。第一支撑组件341和第二支撑组件342的设置一方面增强了锚护作业时的结构稳定性,另一方面第一支撑组件341和第二支撑组件342可独立作业,从而提高了撑顶的可靠性。
在一些实施例中,第一支撑组件341包括第一支撑驱动器3411、横杆3412和第二遮挡件(未示出),第一支撑驱动器3411与作业平台32相连,第一支撑驱动器3411的自由端适于与巷道顶板撑顶, 横杆3412与第一支撑驱动器3411的自由端相连,第二遮挡件连接在横杆3412和作业平台32之间,第二遮挡件适于在第一支撑驱动器3411撑顶时展开以阻隔煤岩。
具体地,如图16所示,第一支撑驱动器3411可以为液压伸缩缸,第一支撑驱动器3411沿着上下方向延伸,第一支撑驱动器3411的顶端适于与巷道顶板撑顶。横杆3412固定在第一支撑驱动器3411的顶部,横杆3412沿着左右方向延伸。第二遮挡件可以为链帘,第二遮挡件的顶端与横杆3412相连,第二遮挡件的底端与第一座3311相连,由此,在第一支撑驱动器3411伸展时,第二遮挡件可以在横杆3412的带动下展开,从而起到遮挡第一钻架组件33的作用,进一步保护了设备和操作人员。
可选地,如图16所示,第一支撑驱动器3411的顶端设有撑顶板,撑顶板可以为一块矩形板,撑顶板能够增大与巷道顶板的作用面积,从而增强了稳固效果。
可以理解的是,在其他一些实施例中,第二遮挡件也可以为胶皮等柔性遮挡件。
在一些实施例中,第一支撑组件341包括多个导向杆3413,多个导向杆3413沿着横杆3412的延伸方向间隔布置,导向杆3413连接在横杆3412和作业平台32之间,导向杆3413适于限制第一支撑驱动器3411的驱动方向。
具体地,如图16所示,导向杆3413可以设有两个,第一支撑驱动器3411可以设在两个导向杆3413的中间,两个导向杆3413的其中一个导向杆3413的顶端与横杆3412的一端相连、底端与第一座3311相连,另一个导向杆3413的顶端与横杆3412的另一端相连、底端与第一座3311相连。导向杆3413可以包括内杆和外杆,外杆固定在第一座3311上,内杆导向配合在外杆内,导向杆3413起到导向效果和增强结构强度的效果。
可选地,第一遮挡件326可以与外杆固定相连。
在一些实施例中,第二支撑组件342包括支撑内筒3422、支撑外筒3421和第二支撑驱动器3424,支撑外筒3421设于作业平台32,支撑内筒3422配合在支撑外筒3421内,且支撑内筒3422相对于支撑外筒3421可滑移,第二支撑驱动器3424设于支撑外筒3421内,第二支撑驱动器3424的一端与支撑外筒3421相连,第二支撑驱动器3424的另一端与支撑内筒3422相连,第二支撑驱动器3424适于驱动支撑内筒3422移动以使第二支撑组件342与截割装置2撑顶。
具体地,如图17和图18所示,支撑内筒3422和支撑外筒3421均为方形筒,支撑外筒3421固定在作业平台32的前侧或第一座3311的前侧,支撑内筒3422配合在支撑外筒3421内,第二支撑驱动器3424可以为液压伸缩缸,第二支撑驱动器3424可以设在支撑外筒3421内,第二支撑驱动器3424的顶端与支撑外筒3421相连,第二支撑驱动器3424的底端与支撑内筒3422相连,通过第二支撑驱动器3424的伸展可以实现支撑内筒3422的向下移动,进而可以实现支撑内筒3422的底端和截割装置2的撑顶。
由于第二支撑驱动器3424设在支撑外筒3421内,第二支撑驱动器3424在使用时仅需要承受轴向作用力,而剪切作用力则主要通过支撑内筒3422和支撑外筒3421承受,从而增强了第二支撑组件342的结构强度,保证了结构的稳定性和结构强度。
在一些实施例中,第二支撑组件342包括压块3423,压块3423可转动地与支撑内筒3422的自由端相连,压块3423具有贴合面,压块3423适于在第二支撑组件342与截割装置2撑顶时转动以使贴合面和截割装置2贴合。
具体地,如图17和图18所示,压块3423可以为三角型块,压块3423可以通过枢轴可转动地与支撑内筒3422的底端相连,压块3423的底侧表面形成贴合面,在重力作用下压块3423的贴合面始终位于下方。当第二支撑组件342伸展后,压块3423可以与截割装置2接触,且压块3423可以在截割装置2的贴合作用下自行转动,从而使得压块3423上的贴合面能够充分和截割装置2贴合,压块3423的设置一方面增强了摩擦作用面积,进而增强了稳固效果,另一方面压块3423具有缓冲效果,能够在锚杆作业时缓冲力的传递。
在一些实施例中,截割装置2上设有撑顶部22,撑顶部22沿着机架1的长度方向延伸以在作业平台32调整至不同的伸缩量后满足对压块3423的支撑。
具体地,如图4所示,撑顶部22可以与截割装置2一体设置,撑顶部22为长条状,且撑顶部22 大体沿着前后方向延伸。当第二支撑组件342伸展后,第二支撑组件342的压块3423可以顶压在撑顶部22上,从而实现第二支撑组件342和截割装置2的撑顶。
由于撑顶部22具有沿着前后方向延伸的尺寸,当作业平台32调整至不同的伸缩量时,压块3423依然能够压在撑顶部22上,满足了作业平台32不同地伸缩量的作业要求,进而使得第一钻架组件33能够满足不同排距的锚杆打设要求。
可选地,撑顶部22的顶面用于与压块3423的贴合面贴合,撑顶部22的顶面沿着从后至前的方向倾斜向下。由此,作用在撑顶部22上的作用力产生向后的作用分力,而掘锚机100的重心位于后侧,后侧具有较大的摩擦作用,从而能够有效抵消作用分力,保证了锚护作业的稳定性。
在一些实施例中,支撑内筒3422包括内筒段和延伸段,内筒段导向配合在支撑外筒3421内,延伸段设于内筒段的自由端并与内筒段呈夹角,延伸段向机架1一侧延伸,压块3423可转动地与延伸段的自由端相连。
具体地,如图17和图18所示,内筒段沿着上下方向延伸,延伸段沿着前后方向延伸,延伸段的前端与内筒段的底端相连,压块3423在转动装配在延伸段的后端。由此,在作业平台32的前端伸展至截割滚筒21前侧时,压块3423依然能够位于截割装置2上方并实现与截割装置2的顶压,延伸段的设置能够增加作业平台32的前探位移量,进而能够增加第一钻架组件33的作业范围。
在一些实施例中,第一支撑组件341包括多个第三支撑驱动器3414和顶棚板3415,多个第三支撑驱动器3414并行间隔布置,第三支撑驱动器3414的一端与作业平台32相连,第三支撑驱动器3414的另一端与顶棚板3415可转动地相连,顶棚板3415适于通过多个第三支撑驱动器3414的伸展实现与巷道顶板的撑顶,且顶棚板3415可通过将多个第三支撑驱动器3414调至不同地伸缩量实现倾斜调整。
具体地,如图21所示,第三支撑驱动器3414可以为液压伸缩油缸,第三支撑驱动器3414可以设有三个,其中一个设在作业平台32前侧,剩余两个设在后侧且沿着左右方向并行间隔布置。三个第三支撑驱动器3414的底端均可以与作业平台32固定相连,例如,可以通过螺栓安装固定,由此,避免了第三支撑驱动器3414摆动的情况,使得第三支撑驱动器3414仅能够进行上下方向的伸缩运动。
第三支撑驱动器3414的顶端可以与顶棚板3415铰接或枢转相连,由此,顶棚板3415可以相对第三支撑驱动器3414摆动。使用过程中,通过控制三个第三支撑驱动器3414同步伸展可以实现顶棚板3415的升起,从而使得顶棚板3415可以与巷道顶板撑顶。当巷道顶板倾斜或不平时,可以将三个第四支撑驱动器3432调至不同的伸缩量,从而使得顶棚板3415倾斜布置,提高了对巷道顶板的适应性。
可选地,三个第三支撑驱动器3414可以均通过枢轴与顶棚板3415相连,且三个枢轴均沿着左右方向延伸,由此,顶棚板3415可以在前后方向倾斜调整。
在一些实施例中,顶棚板3415包括主顶棚34151、内顶棚34152和外顶棚34153,多个第三支撑驱动器3414与主顶棚34151相连,内顶棚34152可转动地与主顶棚34151相连且位于主顶棚34151的内侧,内顶棚34152和主顶棚34151之间设有第一顶棚驱动器3416,第一顶棚驱动器3416适于倾斜撑顶内顶棚34152以实现内顶棚34152的上下摆动,外顶棚34153可转动地与主顶棚34151相连且位于主顶棚34151的外侧,外顶棚34153和主顶棚34151之间设有第二顶棚驱动器3417,第二顶棚驱动器3417适于倾斜撑顶外顶棚34153以实现外顶棚34153的上下摆动。
具体地,如图22至24所示,内顶棚34152可以通过枢轴转动装配在主顶棚34151的内侧,第一顶棚驱动器3416可以设在主顶棚34151和内顶棚34152的下方,第一顶棚驱动器3416的一端可以与主顶棚34151铰接,另一端可以与内顶棚34152铰接,通过第一顶棚驱动器3416可以实现内顶棚34152的上下摆动。外顶棚34153可以通过枢轴转动装配在主顶棚34151的外侧,第二顶棚驱动器3417可以设在主顶棚34151和外顶棚34153的下方,第二顶棚驱动器3417的一端可以与主顶棚34151铰接,另一端可以与外顶棚34153铰接,通过第二顶棚驱动器3417可以实现外顶棚34153的上下摆动。
内顶棚34152和外顶棚34153的设置一方面能够增大第一支撑组件341与巷道顶板的作用面积,另一方面使得顶棚板3415的形状可调,从而提高了顶棚板3415对巷道顶板的适应性。另外,在掘锚机移动的过程中,使得顶棚板3415可以收缩,从而提高通过性。
在一些实施例中,第一支撑组件341包括限位外筒3418和限位内筒3419,限位外筒3418与作业 平台32相连,限位内筒3419导向滑移配合在限位外筒3418内并与顶棚板3415相连,限位外筒3418和限位内筒3419罩在第三支撑驱动器3414的外侧以在第三支撑驱动器3414伸缩时限制第三支撑驱动器3414的伸缩方向。
具体地,如图24所示,限位外筒3418和限位内筒3419的横截面可以均为方形,由此可以实现限位内筒3419和限位外筒3418的止转装配。限位外筒3418可以通过螺栓与作业平台32的前端相连,且限位外筒3418沿着上下方向延伸,限位内筒3419导向配合在限位外筒3418内,限位内筒3419的顶端可以与主顶棚34151转动装配。由此,限位内筒3419仅可以沿着限位外筒3418的延伸方向移动,从而起到了限制第三支撑驱动器3414伸缩方向的作用,例如,当第三伸缩器的上下两端分别与作业平台32和顶棚板3415转动装配时,可以起到避免第三伸缩器摆动的作用。

使用时,可以通过提升油缸驱动滑移板上移,进而可以实现第三锚钻352的上下位置的移动。滑移板和第三锚钻352之间的回转驱动则可以驱动第三锚钻352在左右方向上摆动,从而可以实现对锚杆打设方位的调整。
需要说明的是,使用过程中可以通过将作业平台32调整至不同的伸缩量,从而可以实现第一钻架组件33和第二钻架组件35间距的调整,进而满足了对不同的锚护排距的适应性。
