图 2示出了根据图 1的实施例的塔式起重机的托绳装置添加销轴连接座后的俯视 结构示意图; 图 3示出了根据图 1的实施例的塔式起重机的托绳装置添加销轴连接座后的左视 结构示意图; 图 4示出了根据本发明的实施例的托绳装置与单小车配合工作时的结构示意图; 以及 图 5示出了根据本发明的实施例的托绳装置与双小车配合工作时的结构示意图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是, 在不冲突的 情况下, 本申请中的实施例及实施例中的特征可以相互组合。 如图 1至图 3所示, 根据本发明的实施例, 提供了一种托绳装置 60, 包括支架 61 和设置在支架 61的两个相对端的导向部 62,导向部 62的第一端设置有导向机构 621, 至少一个导向部 62的第二端与支架 61之间可拆卸地固定连接,位于支架 61第一端的 导向机构 621向支架 61的第二端延伸, 位于支架 61第二端的导向机构 621向支架 61 的第一端延伸, 且两个导向机构 621相对设置。 由于至少一个导向部 62的第二端与支 架 61之间可拆卸地固定连接,因此从起重臂架上安装或者拆卸托绳装置 60都很方便, 也可以及时进行更换。 在本实施例中, 吊绳包括起吊钢丝绳和变幅钢丝绳。 托绳装置 60可以通过两个相对设置的导向部 62沿起重臂架的长度方向可移动地 设置在起重臂架上, 在起重臂架的合适位置处设置托绳装置 60后,将吊绳搭设在托绳 装置 60上, 就可以通过托绳装置 60对吊绳起到支撑作用, 因而托绳装置 60能够适当 调整塔机起重臂上的吊绳两个吊点之间的距离, 减小吊绳的下垂量, 保证塔机起重臂 的正常工作。 支架 61包括横杆 611, 托绳装置 60的导向部 62包括竖杆 625, 竖杆 625的第一 端设置有导向机构 621, 第二端与支架 61的横杆 611固定连接。 导向部 62通过竖杆 625固定设置在支架 61的横杆 611上, 横杆 611和竖杆 625之间通过加强筋连接。 优 选地, 在横杆 611的两端端部设置有垂直于横杆 611的过渡杆 612, 横杆 611和竖杆 625之间通过过渡杆 612连接。 在过渡杆 612与竖杆 625之间以及过渡杆 612与横杆 611之间均设置有加强筋。 导向机构 621包括滚轮 622, 滚轮 622位于两个导向部 62 所形成的导向空间内,且位于支架 61两端的两个竖杆 625上的滚轮 622相对设置。滚 轮 622的转轴方向平行于支架 61的长度方向,且两个相对设置的滚轮 622位于同一转 动轴线上。 托绳装置 60通过滚轮 622可转动地设置在起重臂架的下弦杆上。 与支架 61可拆卸连接的导向部 62包括第二端与竖杆 625固定连接的立柱 624, 导向机构 621固定设置在立柱 624的第一端。 立柱 624与竖杆 625之间通过连接法兰 和高强度螺栓固定连接在一起。 滚轮 622固定设置在导向机构 621的立柱 624的第一 端上 。 导向部 62还包括可转动地设置在立柱 624上的侧导向轮 623, 侧导向轮 623位于 与立柱 624安装滚轮 622—侧相邻的两侧, 且侧导向轮 623延伸至导向空间。 侧导向 轮 623的转轴方向平行于立柱 624的长度方向,且在托绳装置 60安装在起重臂架上之 后, 侧导向轮 623与起重臂架的下弦杆 (包括臂根部下弦杆和臂尖部下弦杆) 的外侧 壁之间相抵接, 从而使起重臂架保持在导向空间内, 而不会从托绳装置 60中脱出, 不 仅减小了托绳装置 60运动过程中与起重臂架之间的摩擦力, 也保证了托绳装置 60安 装结构的稳定性和可靠性。 在立柱 624的两侧均设置侧导向轮 623, 能够进一步保证 托绳装置 60的结构的稳定性。 支架 61的横杆 611上设置有托轮 65, 托轮 65的两端设置有安装板 651, 安装板 651固定设置在支架 61上, 托轮 65可转动地设置在安装板 651上, 位于托轮 65两端 的两个相对设置的安装板 651之间形成限位空间。 两个相对设置的安装板 651远离横 杆 611 的一端向外弯折, 形成上大下小的限位空间, 更加便于吊绳的引入。 塔式起重 机的吊绳设置在两个相对设置的安装板 651之间, 并搭设在对应的托轮 65上。 支架 61的横杆 611上沿长度方向可以设置多个托轮 65, 分别用于托起不同类别 的吊绳。 通过这种设置结构, 在某种程度上也可以防止塔式起重机的吊绳之间乱绳。 托绳装置 60也可以不设置托轮 65,而是直接将吊绳设置在支架 61的横杆 611上, 此时为了减小摩擦, 降低横杆 611对吊绳运动的阻碍作用, 可以将横杆设置为圆杆, 然后将吊绳搭设在横杆 611上。 为了防止乱绳, 还可以在横杆 611上沿长度方向设置多个限位结构, 然后将不同 类型的吊绳分别设置在不同的限位结构中, 然后将限位结构中支撑吊绳的部分设置为 圆弧支撑面, 以减小限位结构对吊绳的摩损和阻碍。 支架 61的横杆 611上还固定设置有系绳机构 66, 系绳机构 66包括固定设置在支 架 61上的螺杆安装座 661, 螺杆安装座 661上固定设置有沿导向部 62的导向方向延 伸的两个连接杆 662, 两个连接杆 662反向设置, 且分别位于横杆 611的两侧, 连接 杆 662上具有用于系绳的折弯部 663。 优选地, 螺杆安装座 661上设置有螺纹孔, 连 接杆为螺纹连接杆, 螺纹连接杆与螺杆安装座 661之间螺纹连接。通过螺纹配合结构, 可以调节螺纹连接杆的伸出长度,也就可以调整设置在两个托绳装置 60之间的连接件 的松紧度。 在托绳装置 60上还固定设置有销轴连接座 64, 销轴连接座 64上设置有销轴连接 孔。托绳装置 60可以通过该销轴连接孔与塔式起重机上的其它部件之间实现连接, 以 便根据塔式起重机的具体结构来决定托绳装置 60的设置方式。 托绳装置 60的销轴连 接座 64的具体使用状况将会在下面的操作方法中进行详细描述。在这里,连接托绳装 置 60的销轴通过铰链等连接件连接在托绳装置 60或者起重臂架上, 在不使用该销轴 时, 也能够防止销轴丢失。 结合参见图 4和图 5所示, 根据本发明的实施例, 提供了一种塔机起重臂, 包括 起重臂架和可移动地设置在起重臂架上的小车,起重臂架包括两个平行设置的下弦杆, 塔机起重臂还包括上述的托绳装置 60。 当小车为一个时, 托绳装置 60至少为两个, 分别为第一托绳装置 60a和第二托绳装置 60b,第一托绳装置 60a和第二托绳装置 60b 分别设置在小车的两侧, 且第一托绳装置 60a设置在小车的靠近起重臂架的臂根的一 侧, 第二托绳装置 60b设置在另一侧。两个托绳装置 60之间通过连接件连接, 且托绳 装置 60通过导向部 62沿起重臂架的长度方向可移动地设置在起重臂架的下弦杆 (包 括臂根部下弦杆和臂尖部下弦杆)上, 塔机起重臂的吊绳搭设在托绳装置 60上。两个 托绳装置 60之间的连接件可以为刚性连接件或者防坠绳等, 优选地, 当两个托绳装置 60之间仅通过连接件进行连接时, 该连接件为刚性连接件。 通过刚性连接件能够很好 地控制两个托绳装置 60之间的间距, 即使小车发生移动, 两个托绳装置 60也会随之 发生联动, 从而始终保持对吊绳的托起作用, 减小吊绳的下垂量, 保证塔机起重臂的 正常工作。 刚性连接件可以根据起重臂架的长度而选择合适的长度, 因而能够提高对 吊绳的防坠作用。 当两个托绳装置 60之间是通过第一防坠绳 68a连接时,可以在起重臂架的上部设 置多个滑轮 69, 然后将第二防坠绳 68b绕设在滑轮 69上之后, 最终连接在两个托绳 装置 60上, 并与两个托绳装置 60之间的第一防坠绳 68a—起, 形成环形传动连接结 构。 当小车运动到一个托绳装置 60所在的位置, 并带动托绳装置 60—起运动时, 由 于此环形传动连接结构, 使得另一个托绳装置 60也随之发生运动, 并通过环形传动连 接结构保持两个托绳装置 60之间的间距, 从而保证托绳装置 60始终起到较好的托绳 和防坠效果。在本发明的各实施例当中, 用于绕设第二防坠绳 68b的滑轮均为定滑轮。 在连接防坠绳时,位于两个托绳装置 60之间的第一防坠绳 68a的两端分别连接在 两个托绳装置 60内侧的螺纹连接杆的折弯部 663上, 绕设在滑轮 69上的第二防坠绳 68b的两端分别连接在两个托绳装置 60外侧的螺纹连接杆的折弯部 663上, 当托绳装 置 60与第一防坠绳 6Sa和第二防坠绳 6Sb之间连接完成后, 如果防坠绳过松, 就会影 响托绳装置 60对吊绳的防坠效果,此时可以通过旋转螺纹连接杆的方式来将防坠绳拉 紧, 使防坠绳的设置满足使用要求。 当小车为两个时, 小车包括主小车 35和副小车 34, 托绳装置 60还包括第三托绳 装置 60c, 第一托绳装置 60a、 副小车 34、 第三托绳装置 60c、 主小车 35和第二托绳 装置 60b沿臂根部 331到臂尖部 332的方向依次设置在起重臂架上,第一托绳装置 60a、 第二托绳装置 60b和第三托绳装置 60c之间可选择地通过连接件连接。 由于副小车 34 根据施工需要具有使用状态和非使用状态, 因此, 第一托绳装置 60a,第二托绳装置 60b和第三托绳装置 60c之间可选择地通过连接件连接, 就可以根 据副小车 34的工作状态来设定第一托绳装置 60a、 第二托绳装置 60b和第三托绳装置 60c的连接关系。 当副小车 34处于非使用状态时, 就需要使用到之前提到过的销轴连 接座 64, 此时可以通过销轴连接座 64将第一托绳装置 60a固定连接在臂根部 331上, 并将副小车 34与第一托绳装置 60a固定连接。此时, 第二托绳装置 60b和第三托绳装 置 60c之间具有连接关系, 但第二托绳装置 60b和第三托绳装置 60c与第一托绳装置 60a之间均无连接关系, 第一托绳装置 60a处于闲置状态。 当副小车 34也处于使用状态时, 就需要将第一托绳装置 60a和第二托绳装置 60b 沿臂根部 331到臂尖部 332的方向通过连接件连接, 该连接件可以为刚性连接件或者 防坠绳。 当连接件为第一防坠绳 68a时, 起重臂架上设置有多个滑轮 69, 第一托绳装 置 60a、 第二托绳装置 60b和第三托绳装置 60c之间通过绕设在滑轮 69上的第二防坠 绳 68b和连接在托绳装置 60之间的第一防坠绳 68a形成环形传动连接结构。 当小车仅包括主小车 35时, 吊绳防坠方法包括: 将第一托绳装置 60a和第二托绳 装置 60b分别可移动地设置在主小车 35两侧的起重臂架下弦杆上, 将两个托绳装置 60通过连接件 (第一防坠绳 68a或者刚性连接件)连接, 并将第二防坠绳 68b的一端 固定连接在第一托绳装置 60a外侧的螺栓连接杆上, 第二防坠绳 68b的另一端绕设在 多个滑轮 69上之后, 固定连接在第二托绳装置 60b外侧的螺栓连接杆上,使两个托绳 装置 60通过第二防坠绳 68b和连接件形成环形传动连接结构;然后将起吊钢丝绳和变 幅钢丝绳分别从第一托绳装置 60a和第二托绳装置 60b的托轮 65上绕过,并将起吊钢 丝绳和变幅钢丝绳分别设置在托轮 65两端的安装板 651所形成的限位空间内,然后连 接在主小车 35上。 参见图 4所示, 当小车包括主小车 35和副小车 34, 但仅使用主小车 35, 副小车
34处于闲置状态时, 吊绳防坠方法包括: 首先将第一托绳装置 60a可移动地固定连接 在起重臂架的臂根部 331 ; 然后将副小车 34固定连接在第一托绳装置 60a上; 将第二 托绳装置 60b和第三托绳装置 60c分别可移动地设置在主小车 35两侧的起重臂架的下 弦杆上, 并使第二托绳装置 60b位于主小车 35与副小车 34之间, 然后在第二托绳装 置 60b和第三托绳装置 60c之间用第一防坠绳 68a进行连接, 使第一防坠绳 68a的第 一端固定连接在第二托绳装置 60b的内侧的螺栓连接杆上, 将第一防坠绳 68a的第二 端固定连接在第三托绳装置 60c的内侧的螺栓连接杆上; 将第二防坠绳 68b的一端固 定连接在第二托绳装置 60b的外侧的螺栓连接杆上, 第二防坠绳 68b的另一端绕设在 多个滑轮 69上之后, 固定连接在第三托绳装置 60c外侧的螺栓连接杆上, 使两个托绳 装置 60通过两根防坠绳形成环形传动连接结构;将起吊钢丝绳和变幅钢丝绳分别从第 二托绳装置 60b和第三托绳装置 60c的托轮 65上绕过后连接在主小车 35上。 使用单小车进行施工时,防坠原理如下:托绳装置 60同小车一样放置于起重臂上, 起吊钢丝绳自由的放于托绳装置 60的其中一个托轮 65上, 变幅钢丝绳自由放于另一 个托轮 65上, 托绳装置 60通过滚轮 622可在起重臂架上来回运动。 当使用单小车时 第一托绳装置 60a、 副小车 34与起重臂架固定连接在一起, 不会在起重臂架上移动。 当主小车 35在起重臂上移动时, 到碰触到第三托绳装置 60c继续往第三托绳装置 60c 所在侧运动时, 由防坠绳牵引第二托绳装置 60b往第三托绳装置 60c所在侧运动。 同 样当小车往第二托绳装置 60b方向运动碰触后, 会牵引第三托绳装置 60c运动。 当主 小车 35在两个托绳装置 60中间运动时则两个托绳装置 60不动。这样控制好第二托绳 装置 60b和第三托绳装置 60c之间的第一防坠绳 68a的长度, 就相当于将起重臂的跨 度缩短一半, 吊绳的下垂量就能够得到很好的控制。 参见图 5所示, 当小车包括主小车 35和副小车 34, 且同时使用主小车 35和副小 车 34时, 吊绳防坠方法包括: 首先将第一托绳装置 60a可移动地设置在起重臂架的臂 根部 331 ; 然后将第三托绳装置 60c可移动地设置在副小车 34与主小车 35之间的起 重臂架的下弦杆上,将第二托绳装置 60b可移动地设置在主小车 35的靠近臂尖侧的起 重臂架的下弦杆上; 通过第一防坠绳 68a连接第一托绳装置 60a和第二托绳装置 60b, 使第一防坠绳 68a的第一端固定连接在第一托绳装置 60a的内侧的螺栓连接杆上, 将 第一防坠绳 68a的第二端固定连接在第二托绳装置 60b的内侧的螺栓连接杆上; 将第 二防坠绳 68b的一端固定连接在第一托绳装置 60a的外侧的螺栓连接杆上, 第二防坠 绳 68b的另一端绕设在多个滑轮 69上之后,固定连接在第二托绳装置 60b外侧的螺栓 连接杆上,使两个托绳装置 60通过第二防坠绳 68b和第一防坠绳 68a形成环形传动连 接结构; 将主小车 35和副小车 34固定连接; 将起吊钢丝绳和变幅钢丝绳分别从第一 托绳装置 60a和第三托绳装置 60c的托轮 65上绕过后连接在主小车 35上。 使用双小车进行施工时, 其防坠原理与单小车施工的防坠原理相同, 这里不再赘 述。 根据本发明的实施例, 一种塔机包括塔机起重臂, 该塔机起重臂为上述的塔机起 重臂。 从以上的描述中, 可以看出, 本发明上述的实施例实现了如下技术效果: 托绳装 置包括支架和设置在支架的两个相对端的导向部, 导向部的第一端设置有导向机构, 至少一个导向部的第二端与支架之间可拆卸地固定连接, 位于支架第一端的导向机构 向支架的第二端延伸, 位于支架第二端的导向机构向支架的第一端延伸, 且两个导向 机构相对设置。 托绳装置可以通过导向机构可移动地设置在塔机臂架上, 能够适当调 整塔机起重臂上的吊绳两个吊点之间的距离, 减小吊绳的下垂量, 保证塔机起重臂的 正常工作。 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。 凡在本发明的精祌和原则之内, 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。
