第一致动件 122, 致动所述第一锁定件 121以使第 一锁定件 121在第一打开位置和第一锁定位置之间枢转; 第一弹性件 123 , 在 本实施例中为第一预拉件 123 , 对所述第一锁定件 121施力使之具有朝向所述 第一打开位置的运动趋势。 第二锁定部 9包括: 第二锁定件 91 , 设置成在第二 打开位置和第二锁定位置之间移动, 优选地设置成在第二打开位置和第二锁定 位置之间平移并且所述第二锁定件 91的锁定端设置有向上斜面部分 911; 第二 致动件 92,致动所述第二锁定件 91 以使第二锁定件 91在第二打开位置和第二 锁定位置之间平移; 第二弹性件 93 , 在本实施例中为第二预压件 93 , 对所述 第二锁定件 91 施力使之具有朝向所述第二打开位置的运动趋势。 上述第一预 拉件 123和第二预压件 93优选地可为弹簧。 应当注意, 术语"打开位置 "指的是所述锁定件被释放而伸出所述锁定部时 的位置; 术语"锁定位置"指的是所述锁定件收回到所述锁定部内部并保持固定 时的位置。 所述第一锁定件 121可枢转地连接到所述锁定装置 5、 7的内部, 所述第 一致动件 122可枢转地连接到所述第一锁定件 121上,并且所述第一预拉件 123 的第一端连接到所述锁定装置 5、 7的内部, 所述第一预拉件 123 的第二端连 接到所述第一锁定件 121上。 所述第一致动件 122可释放地固定在所述上、 下 锁定装置 5、 7的内部, 当所述第一致动件 122固定在所述上、 下锁定装置 5、 7的内部时, 所述第一锁定件 121保持在锁定装置内的第一锁定位置处, 并且 使得第一预拉件 123处于预拉状态。 所述第二锁定件 91连接至所述第二致动件 92, 并且在所述第二锁定件 91 和所述第二致动件 92之间设置有所述第二预压件 93。 具体地, 参照图 3-5 , 所 述第二致动件 92包括: 连 4干 922, 其第一端穿过所述第二预压件 93而固定至 所述第二锁定件 91 , 所述连杆 922 的第二端穿过固定至所述锁定装置的底板 924 向外延伸; 偏心轮 921 , 通过偏心转轴 926可 4区转地连接到所述连才干 922 的第二端, 所述偏心轮 921具有相互平行的第一面和第二面以及连接所述第一 面和第二面的凸弧面, 所述偏心转轴 926距离所述第一面的距离大于所述偏心 转轴距离所述第二面的距离。 所述偏心轮 921与所述连杆 922之间还设置有穿 过所述偏心轮 921与所述连 4干 922的可插拔的销 923 , 所述偏心轮 921上还设 置有操作手柄 925。如图 5中所示,所述偏心轮 921的第一面 4民靠所述底板 924, 这使得所述第二锁定件 91 保持在锁定装置内的第二锁定位置处并且使得第二 预压件 93处于预压状态,并且所述销 923插入所述偏心轮 921和所述连杆 922 中, 防止所述偏心轮 921枢转, 从而确保所述偏心轮 921不会因意外操作而运 动。 此外, 所述下锁定装置 7还包括支撑脚 13 , 该支撑脚 13可枢转地铰接在 下锁定装置 7的下端, 并且该支撑 έρ 13可以在下锁定装置 7的从向方向和水 平方向之间枢转, 图 3示出了该支撑脚 13处于锁定装置的水平方向上。 在顶升工作开始时, 将下锁定装置 7的支撑脚 13释放, 即, 使该支撑脚 13枢转到锁定装置水平方向上, 从而使该支撑脚 13支撑于楼面 4上。 通过操 纵手柄 925来操纵偏心轮 921。 所述偏心轮 921的第一面 4民靠所述底板 924, 从而使得所述第二锁定件 91 保持在锁定装置内的第二锁定位置处, 并且将所 述销 923插入所述偏心轮 921和所述连才干 922中,以防止所述偏心轮 921才区转。 并且通过对第一致动件 122施加力来释放下锁定装置 7和上锁定装置 5的第一 锁定件 121。 这里应当注意, 由于第一锁定件 121的锁定端具有向下斜面部分 1211 , 因此第一锁定件 121在相对于立柱 1的锁孔下行时虽然可以啮合进锁孔 内, 但是当向下斜面部分 1211接触锁孔的壁时, 使得第一锁定件 121 缩回锁 定装置 5、 7 中, 从而不起锁定作用, 第一锁定件 121会继续下行, 而第一锁 定件 121相对于立柱 1的锁孔上行时, 在第一预拉件 123的作用下, 第一锁定 件 121可以啮合入锁孔内, 将锁定装置 5、 7锁定。 然后液压缸 6动作, 上锁 定装置 5向上移动, 当到达锁孔位置时, 第一锁定件 121在第一预拉件 123的 作用下枢转到第一打开位置, 从而伸出锁定装置 5并啮合入立柱 1和导轨 2的 锁孔内而锁定卡住, 随后液压缸 6伸长一行程, 带动立柱 1上升。 当液压缸 6 伸长行程结束, 液压缸 6收回, 由于下锁定装置 7的第一锁定件 121在第一预 拉件 123的作用下枢转到第一打开位置, 而使得第一锁定件 121啮合入立柱 1 和导轨 2的锁孔内而锁定立柱, 并且上锁定装置 5的第一锁定件 121在液压缸 6收回时下行而不起锁定作用。 因此当液压缸 6收回至行程即将结束时, 上锁 定装置 5的第一锁定件 121在第一预拉件 123的作用下枢转到第一打开位置, 而使得第一锁定件 121啮合入立柱 1和导轨 2的锁孔内而锁定卡住, 此时液压 虹 6再次伸长, 带动立柱 1继续上升。 当顶升机构顶升完成后 (即液压虹 6 仍有一定伸长行程的状态), 可手动 地通过第一致动件 122将上锁定装置 5和下锁定装置 7的第一锁定件 121收回, 使其处于第一锁定位置。 然后抽出销 923 , 然后将偏心轮 921枢转 180°释放连 杆 922, 在第二预压件 93 的弹力作用下, 偏心轮 921 的第二面抵靠所述底板 924 , 从而连杆 922使得第二锁定件 91从锁定装置中 5、 7伸出。 同时通过偏 心轮 921上的另一通孔将所述销 923插入所述偏心轮 921和所述连杆 922中, 该另一通孔相对于偏心转轴 926 与在偏心轮的第一面 4民靠底板 924 时所述销 923所插入的通孔径向相对。 这里应当注意, 由于第二锁定件 91的锁定端具有 向上斜面部分 911 , 因此第二锁定件 91在相对于立柱 1的锁孔上行时虽然可以 啮合进锁孔内, 但是当向上斜面部分 911接触锁孔的壁时, 使得第二锁定件 91 缩回锁定装置 5、 7中, 从而不起锁定作用, 第二锁定件 91会继续上行, 而第 二锁定件 91相对于立柱 1的锁孔下行时, 在第二预压件 93的作用下, 第二锁 定件 91可以啮合入锁孔内, 将锁定装置 5、 7锁定。 因此, 液压缸 6伸长, 上 锁定装置 5上行, 使得上锁定装置 5的第二锁定件 91在上行行程结束后啮合 入立柱 1和导轨 2的相应锁孔内, 然后, 液压紅 6收缩一行程, 此时上锁定装 置 5由于锁定机构的重量处于锁定状态, 因此下锁定装置 7被提升, 下锁定装 置 7的第二锁定件 91在行程结束时啮合入立柱 1和导轨 2的相应锁孔内, 此 时, 液压缸 6再次伸长, 下锁定装置 7锁定, 上锁定装置 5又再次上行, 经过 多轮爬升循环, 整套顶升机构爬升至第二层楼面 4上方, 整套顶升机构被调整 为处于上锁定装置 5 锁定 (由于顶升机构重量啮合入锁孔内而锁定)、 下锁定 装置 7的第二锁定件 91未啮合入立柱 1和导轨 2的锁孔内以及液压虹 6仍有 足够伸长行程的状态, 此时, 将下锁定装置的第二锁定件 91 收回, 具体地通 过操从手柄 925 4区转偏心轮 921 , 使得所述偏心轮 921的第一面 4民靠所述底板 924 , 从而拉回连 4干 922, 进而使得下锁定装置 7的所述第二锁定件 91保持在 锁定装置内的第二锁定位置处并且使得下锁定装置 7的第二预压件 93处于预 压^! 态, 然后^ 1所述销 923插入所述偏心轮 921和所述连才干 922中, 以防止所 述偏心轮 921枢转。 因此液压虹 6伸长, 下锁定装置 7下降使其支撑脚 13支 撑于楼面 4上, 然后将上锁定装置 5的第二锁定件 91收回, 具体地通过操纵 手柄 925枢转偏心轮 921 , 使得所述偏心轮 921的第一面 4民靠所述底板 924, 从而拉回连杆 922 ,进而使得上锁定装置 5的所述第二锁定件 91保持在锁定装 置内的第二锁定位置处并且使得上锁定装置 5的第二预压件 93处于预压状态, 然后^ 1所述销 923插入所述偏心轮 921和所述连才干 922中, 以防止所述偏心轮 921枢转。 通过第一致动件 122释放第一锁定件 121 , 使其处于第一打开位置。 液压缸 6动作, 使上锁定装置 5的第一锁定件 121啮合入立柱 1和导轨 2的锁 孔内, 开始立柱顶升循环。 由此可见, 立柱顶升和顶升机构爬升统一于液压紅 6 的动作中, 实现了真正意义的全自动顶升。 本发明将顶升动力源同顶升机构 爬升动力源统一于液压虹, 通过简单的切换可使液压虹动作在塔身顶升和顶升 机构自动爬升过程中互不千 4尤, 真正实现了顶升全过程的自动化。 另外, 在图 6所示的另一实施例中, 第一锁定部 22位于第二锁定部 29的 下方。 第一锁定部 22的第一锁定件 221被设置成在第一打开位置和第一锁定 位置之间平移, 并且第二锁定部 29的第二锁定件 291被设置成在第二打开位 置和第二锁定位置之间 ^区转。具体工作原理与上述实施例相似,在此不再描述。 另外, 应当注意, 还可以将第一锁定件和第二锁定件都设置成在打开位置 和锁定位置之间枢转或平移。 第一弹性件还可以为预压件, 第二弹性件还可以 为预拉件。 以上仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的 技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
