活动套3的外表面上固定有丝杆固定架15，丝杆5插入到丝杆固定架15中且与丝杆固定架15转动连接，在丝杆固定架15上设有一个与丝杆5啮合的链轮16，所述的链轮16与丝杆驱动器6连接，丝杆固定架15上设有轴承，优选的设置两个对称的轴承，链轮16位于两个轴承中间，当丝杆驱动器6驱动链轮16周向旋转时，所述的链轮16能驱动丝杆5沿轴向前后移动。
连接梁2包括用距离调节套17连接的前梁18和后梁19，其中后梁19一端固定有活动套3，另一端插入到距离调节套17内并与距离调节套17螺接固定，前梁18一端插入到距离调节套17内并与距离调节套17螺接固定，另一端连接有一个轨道组件20。
再结合图8和图9所示，轨道组件20包括固定在建筑物101上的导轨21及与导 轨21相配适且卡接配合的滑块22，所述的前梁18与滑块22铰接。在本实施例中，建筑物101为房屋、墙壁或桥梁等具有竖直面的建筑构件。
如图8所示，导轨21为C形导轨，如图9所示，导轨21为H形导轨，所述的滑块22上设有一个滑块制动器23，所述的滑块制动器23能使滑块22和导轨21固定连接或活动连接，导轨21固定在与建筑物固定连接的导轨固定机构24上，滑块制动器23可以是气缸或油缸。再结合图2所示，滑块22上还设有滑轮28，便于滑块22与导轨21的顺畅滑动。
导轨固定机构24包括埋入到建筑物101内部的预埋板25，所述的预埋板25与导轨21平行，在预埋板25上固定有若干横截面呈L形的抗拉板26，所述的预埋板25与建筑物通过锚角螺丝27固定连接，所述的导轨21与预埋板25固定连接。
本发明的工作原理是：当塔台100需要改变位置时，塔吊100可以通过底部的行走机构行走，滑块22随着导轨21滑动，在这个过程中，如果塔吊100与建筑物101之间的距离是固定的，则塔吊100可以顺利的行走，如果行走过程中距离有变化，则滑块22与导轨21会卡死，塔吊100不能行走。
为了在塔吊100行走过程中实时调整与建筑物101之间的距离，支撑梁1与连接梁2活动连接的方式起到了至关重要的作用。具体的说，当塔吊100需要行走时，转盘8转动至合适位置，使定位块卡孔9和丝杆定位块7处于同一平面时，丝杆驱动器6带动链轮16转动，丝杆5脱离转盘8，支撑梁1和连接梁2为活动连接，支撑梁1能在活动套3内前后移动，从而调整塔吊100与建筑物101之间的距离。
当塔吊100行走到位时，链轮16转动带动丝杆5靠近转盘8，并使丝杆定位块7插入到定位块卡槽10内，转盘8在转盘驱动器11作用下转动并卡住丝杆定位块7，支撑梁1与连接梁2固定连接，从而使塔吊100与建筑物101之间固定。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了支撑梁1、连接梁2、活动套3、丝杆定位组件4、丝杆5、丝杆驱动器6、丝杆定位块7、转盘8、定位块卡孔9、定位块卡槽10、转盘驱动器11、定位盘12、转动盘13、转盘支撑柱14、丝杆固定架15、链轮16、距离调节套17、前梁18、后梁19、轨道组件20、导轨21、滑块22、滑块制动器23、导轨固定机构24、预埋板25、抗拉板26、锚角螺丝27等术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本发明的本质；把它们解释成任何一种附加的限制都是与本发明精神相违背的。
