以下结合附图对本申请的具体实施例进行详细说明。应当理解的是，此处所描述的具体实施例仅用于说明和解释本申请，并不用于限制本申请。
下面参考附图描述根据本申请的爬升系统。
如图1和图2所示，在本申请的实施例中，提供一种爬升系统100，其中，爬升系统100包括内爬框1、爬升机构2以及爬带3；内爬框1设置于与建筑物固定的承重梁上；爬升机构2位于内爬框1内侧，爬升机构2包括沿上下方向依次设置的内爬基节21和顶升横梁 22，顶升横梁22通过顶升油缸23和内爬基节21的固定横梁211连接，内爬基节21的底部设置有用于和内爬框1定位配合的伸缩梁213，内爬基节21上靠近底部的位置设置有换步爬爪212，顶升横梁22设置有顶升爬爪221；爬带3吊装于内爬框1的内侧并能相对内爬框1升降，爬带3沿长度方向均匀间隔设置有多个和顶升爬爪221、换步爬爪212定位配合的踏步31，爬带3的长度大于等于爬升机构2的内爬高度且小于内爬高度的二倍。可以理解地，本实施例中的内爬框1可设置于建筑物的电梯井内，也可外挂于建筑物的墙体。
本实施例中的内爬框1为框架式结构，爬升系统100主要应用于起重机，起重机的塔机通常安装于所述内爬基节21上，并随爬升机构2爬升，其中爬升机构2的内爬高度为塔机的能进行爬升的总内爬间距。图1中虚线结构分别为顶升爬爪221和换步爬爪212。
在采用本实施例中的爬升系统100进行爬升操作时，通过顶升油缸23顶固定横梁211，带动内爬基节21上升，直至换步爬爪212超过踏步31，操作换步爬爪212使其落在踏步31上，收缩顶升油缸23，内爬基节21由爬带3支撑，继续回收顶升油缸23，直至位于下方的顶升爬爪221超过一处踏步31，操作顶升爬爪221使其落在爬带3的踏步31上，顶升油缸23伸长，内爬基节21向上爬升，重复步骤以上顶升油缸23的伸缩操作，最终伸缩梁213超过内爬框1后，对伸缩梁213进行伸出操作，使伸缩梁213落在内爬框1上，并将伸缩梁213和内爬框1固定。
本实施例通过将内爬框1设置于与建筑物固定的承重梁上，中置 爬升系统100，需要爬升操作空间小，易于操作，并将换步爬爪212下置于内爬基节21底部靠近顶升爬爪221的位置，相对现有技术中换步爬爪212上置，减小了换步爬爪212和顶升爬爪221之间的间距，使爬升机构2爬升的过程中爬带3需要和爬升机构2配合的长度缩短至爬升机构2总内爬高度的一倍至两倍之间，降低了爬带3的长度，使爬升系统100的原材料成本降低。
在一实施例中，换步爬爪212和顶升爬爪221能分别绕内爬基节21和顶升横梁22转动，换步爬爪212和顶升爬爪221的距离为L1，任意两个踏步31之间的距离为L2，顶升油缸23的顶升行程为L3，换步爬爪212和顶升爬爪221的转动半径均为a，L2＜L3+L1+a＜2*L2。本实施例中具体通过换步爬爪212和顶升爬爪221之间的距离、两个踏步31之间的距离、顶升油缸23的顶升行程以及换步爬爪212和顶升爬爪221的转动半径四者之间的配合，使爬带3需要和爬升机构2配合的长度进一步缩短，从而尽可能地缩短爬带3高度。
在本申请实施例中，换步爬爪212和伸缩梁213下端面的距离为L4，位于顶部的踏步31和位于顶部的内爬框1的距离为L5，L5＜L3-(L2-L1)-L4。本实施例中配合换步爬爪212和顶升爬爪221之间的距离以及顶升油缸23的顶升行程，使爬带3需要和爬升机构2配合的长度缩短至和爬升机构2的内爬高度相同。
如图2所示，在本申请实施例中，爬升系统100还包括安装于内爬框1顶部的支撑块4，支撑块4能在避让位置和支撑位置之间往复翻转，并在支撑位置限位支撑爬带3。在一实施例中，支撑块4能相 对内爬框1翻转180度，当爬带3下落的过程中，支撑块4处于避让位置，此时支撑块4朝向内爬框1外侧，爬带3竖直下落到一定位置后，翻转支撑块4，使支撑块4在支撑位置限位支撑爬带3，爬带3需要上升时，可解除支撑块4对爬带3的限位支撑，通过驱动件吊升爬带3并将支撑块4翻转至避让位置。本实施例中仅通过翻转支撑块4就能实现爬带3的装拆，使得爬带3装拆无需借助辅助工具，降低了转运和使用成本。
在一实施例中，支撑块4设置有用于限位爬带3的限位件41和用于供爬带3穿过的定位槽42，限位件41和定位槽42沿内爬框1的宽度方向依次排列。本实施例中定位槽42贯穿支撑块4且一侧开口，能在爬带3下落到一定位置后，翻转支撑块4，使爬带3通过开口进入定位槽42内并与定位槽42定位配合，接着可操作限位件41，对爬带3进行限位操作。本实施例中可通过将限位销轴依次贯穿限位件和爬带3的方式，实现对爬带3的限位。并且本申请实施例中，位于支撑位置的限位件41处于定位槽42的外侧。
在一实施例中，内爬框1顶部内侧对应支撑块4设置有加强垫块11，位于支撑位置的支撑块4支撑于加强垫块11上。本实施例中加强垫块11的上平面为支撑平面，内爬框1具体通过加强垫块11对支撑块4进行支撑，能避免支撑块4支撑不稳而导致爬带3晃动的情况。
在本申请实施例中，内爬框1设置有支架5，支撑块4通过支撑销轴6铰接于支架5。本实施例中的支架5可焊接于内爬框1，通过支撑销轴6依次贯穿支架5和支撑块4的形式将支撑块4铰接于内爬 框1。如图2所示，支撑块4处于支撑位置，加强垫块11和支撑销轴6共同受力支撑爬带3。
在一实施例中，两个爬带3分别吊装于内爬框1的两侧，内爬基节21的两侧和伸缩梁213的两侧分别对应爬带3设置有换步爬爪212和顶升爬爪221。如图1所示，两个爬带3分别设置于内爬框1的左右两侧，换步爬爪212和顶升爬爪221也均两个为一组，分别与两个爬带3定位支撑配合。
