Description

一种曳引式建筑施工升降机的绕线结构 技术领域
本发明涉及建筑施工升降机领域，特别涉及一种曳引式建筑施工升降机的绕线结构。
背景技术
建筑施工升降机又称施工电梯，常规的建筑施工升降机是一种采用齿轮、齿条啮合方式，使吊笼作升降运动，用以输送施工人员、工具、设备及物料的建筑机械。齿轮齿条式升降机的缺点是升降效率低，噪音大。
发明内容
为了解决上述问题的一个或多个，本发明提供了一种曳引式建筑施工升降机的绕线结构。
根据本发明的一个方面，一种曳引式建筑施工升降机的绕线结构，包括曳引媒介、第一换向轮组、第二换向轮组、曳引机、第三换向轮组和第四换向轮组；
曳引媒介以中部固定的方式与吊笼连接；
曳引媒介的一端经过曳引机后引向第二换向轮组；
曳引媒介的绕过第二换向轮组换向后引向第一换向轮组；
曳引媒介绕过第一换向轮组换向后引向升降机的吊笼；
曳引媒介的另一端经过曳引机后引向第三换向轮组；
曳引媒介绕过第三换向轮组换向后引向第四换向轮组；
曳引媒介的绕过第四换向轮组换向后引向升降机的对重；
升降机通过天梁和绕线结构改变井道曳引机的曳引媒介方向能够拉动吊笼上下移动，
曳引媒介为钢丝绳或钢带，天梁能够升降移动。
本发明的有益效果是：本发明采用曳引机和曳引媒介驱动吊笼的升降，曳引机设置相对低位，自曳引机引出的曳引媒介两端分别通过换向轮组换向，再分别与吊笼和对重连接，具有升降效率高、噪音小的优点；本实施方式通过将曳引媒介以中部固定的方式与吊笼连接，曳引媒介的一端预留出足够长度的曳引媒介，在建筑物不断升层的过 程当中，就可以直接使用预留的曳引媒介，使用中部固定的方式，就不需要将曳引媒介剪断，也不需要采用不断接线延长的方式；钢丝绳相对而言制造更加的方便，但是钢带也有扁平设计使接触面积增大，提高曳引摩擦力；同时钢带不需要额外润滑，无油渍污染，比钢丝绳振动幅度低，更平稳舒适，节省电能，使用寿命长，二者各有优势。
在某些实施方式中，第一换向轮组、第二换向轮组、第三换向轮组和第四换向轮组位于同一平面内。
本实施方式的有益效果是：曳引媒介1的力处在同一个竖直平面内，吊笼7以及对重8也都在相同的竖直平面内运动，曳引媒介1的运动阻力最小化。
在某些实施方式中，第一换向轮组包括第一滑轮和第二滑轮，第一滑轮和第二滑轮位于同一平面上，第一滑轮的中心垂线与第二滑轮的中心垂线存在水平距离，曳引媒介绕过第一滑轮后再引向第二滑轮。
本实施方式的有益效果是：第一滑轮的中心垂线与第二滑轮的中心垂线之间存在足够的水平距离，使换向前后的两段曳引媒介之间具有足够的距离，避免曳引媒介与该距离之间的吊笼和对重干涉。
在某些实施方式中，天梁的一端上设有第一立柱，第一滑轮固定于天梁上，第二滑轮固定于第一立柱上。
在某些实施方式中，第一换向轮组为大滑轮，大滑轮的直径至少大于吊笼宽度的一半。
本实施方式的有益效果是：只用一个直径更大的滑轮也能实现曳引媒介的转向和保证转向前后两段曳引媒介之间足够的距离，以保证吊笼和对重的运动不被曳引媒介干涉。
在某些实施方式中，曳引机的下方设有支架，第三换向轮组包括第三滑轮和第四滑轮，第三滑轮位于曳引机的正下方，第四滑轮位于曳引机和吊笼的中间位置，第三滑轮和第四滑轮均安装于支架上。
本实施方式的有益效果是：自曳引机引出的曳引媒介从第三滑轮和第四滑轮的下方绕过后再向上延伸。
在某些实施方式中，第四换向轮组包括第五滑轮和第六滑轮，第五滑轮和第六滑轮位于同一平面上，第五滑轮设置在高于第六滑轮的位置，曳引媒介绕过第五滑轮后从第五滑轮与第六滑轮之间引出，自第四换向轮组引出的曳引媒介介于吊笼与自第三换向轮组引出的曳引媒介之间。
本实施方式的有益效果是：从第五滑轮引出的曳引媒介被第六滑轮向离开吊笼的方向推动适当的距离，使自第四换向轮组引出的曳引媒介下方固接的对重与位于对重左右的吊笼和曳引媒介互不干涉。
在某些实施方式中，天梁上还设有第二立柱，第五滑轮固定于天梁上，第六滑轮固定于第二立柱上。
在某些实施方式中，天梁与第一立柱或第二立柱之间设有至少一条加强拉杆。
本实施方式的有益效果是：加强拉杆可增强第一立柱或第二立柱的牢固程度。

本实施例通过将曳引媒介1以中部固定的方式与吊笼7连接，曳引媒介1的一端预留出足够长度的曳引媒介1，例如该一端预留出的曳引媒介1可盘绕后置于吊笼7顶部。在建筑物不断升层的过程当中，就可以直接使用预留的曳引媒介1，使用中部固定的方式，就不需要将曳引媒介剪断，也不需要采用不断接线延长的方式。
请参考图1，曳引媒介1的一端经过曳引机4后引向第二换向轮组3，经过第二换向轮组3换向后，曳引媒介1向上延伸至第一换向轮组2，经第一换向轮组2换向后，曳引媒介1向下延伸至吊笼7，并与吊笼7的顶部固定连接。自第二换向轮组3引出的曳引媒介1和自第一换向轮组2引出的曳引媒介1之间存在足够的距离，即转向前后的两段曳引媒介1之间具有足够的距离，该距离应使自第二换向轮组3引出的曳引媒介1不干涉吊笼7和对重8的正常升降。
请参考图1，曳引媒介1的另一端经过曳引机4后引向第三换向轮组5，经过第三换向轮组5的换向后，曳引媒介1向上延伸至第四换向轮组6，经第四换向轮组6再次换向后向下延伸至对重8，并与对重8固定连接。自第三换向轮组5引出的曳引媒介1与自第四换向轮组6引出的曳引媒介1之间具有足够的距离，即转向前后的两段曳引媒介1之间具有足够的距离，使二者不互相干涉。
对重8、自第三换向轮组5引出的曳引媒介1以及自第四换向轮组6引出的曳引媒介1处于自第二换向轮组3引出的曳引媒介1与吊笼7之间，因此自第二换向轮组3引出的曳引媒介1与吊笼7之间应 该具有足够的距离，以不干涉对重8、自第三换向轮组5引出的曳引媒介1以及自第四换向轮组6引出的曳引媒介1为限。
请结参考图2，天梁9能够升降移动，从而可以将本发明的升降机应用于建筑物施工当中，因为建筑物是会随着施工不断升高的，所以需要相应的天梁9是可以升降移动的。天梁9固接在已建的建筑体上，例如墙壁或楼板。天梁9的移动的方式通常为将曳引媒介1放松，然后再将天梁9从建筑体上拆除，再将天梁9上移，并与新增的更高处的建筑体固接。
曳引媒介1可以是钢丝绳或钢带，钢丝绳相对而言制造更加的方便，但是钢带也有扁平设计使接触面积增大，提高曳引摩擦力；同时钢带不需要额外润滑，无油渍污染，比钢丝绳振动幅度低，更平稳舒适，节省电能，使用寿命长，二者各有优势。
在一实施例中，第一换向轮组2、第二换向轮组3、第三换向轮组5和第四换向轮组6位于同一平面内。曳引媒介1的力处在同一个竖直平面内，吊笼7以及对重8也都在相同的竖直平面内运动，曳引媒介1的运动阻力最小化。
在一实施例中，请参考图1，第一换向轮组2包括第一滑轮201和第二滑轮202，第一滑轮201和第二滑轮202位于同一平面上，第一滑轮201的中心垂线与第二滑轮202的中心垂线之间存在水平距离，曳引媒介1绕过第一滑轮201后再引向第二滑轮202。经过第一滑轮201和第二滑轮202的转向，将自第二换向轮组3向上引出的曳引媒介1换向成向下引向吊笼7。第一滑轮201的中心垂线与第二滑轮202的中心垂线之间存在足够的水平距离，使换向前后的两段曳引媒介1之间具有足够的距离。
在一实施例中，天梁9的一端上设有第一立柱10，第一滑轮201固定于天梁9上，第二滑轮202固定于第一立柱10上。请参考图3，第一滑轮201中心转轴固接于第一立柱10上，例如通过U形螺栓15固接。
在一实施例中，第一换向轮组2为大滑轮，大滑轮的直径至少大于吊笼7宽度的一半。只用一个直径更大的滑轮也能实现曳引媒介1的转向和保证转向前后两段曳引媒介1之间足够的距离，以保证吊笼7和对重8的运动不被曳引媒介1干涉。
在一实施例中，曳引机4的下方设有支架11，第三换向轮组5包括第三滑轮501和第四滑轮502，第三滑轮501位于曳引机4的正 下方，第四滑轮502位于曳引机4和吊笼7的中间位置，第三滑轮501和第四滑轮502均安装于支架11上。第三滑轮501和第四滑轮502位于同一个竖直平面上，第三滑轮501和第四滑轮502左右设置。自曳引机4引出的曳引媒介1从第三滑轮501和第四滑轮502的下方绕过后再向上延伸。第二换向轮组3设置在第三换向轮组5的上方。
在一实施例中，第四换向轮组6包括第五滑轮601和第六滑轮602，第五滑轮601和第六滑轮602位于同一平面上，第五滑轮601设置在高于第六滑轮602的位置，曳引媒介1绕过第五滑轮601后从第五滑轮601与第六滑轮602之间引出，自第四换向轮组6引出的曳引媒介1介于吊笼7与自第三换向轮组5引出的曳引媒介1之间。从第五滑轮601引出的曳引媒介1被第六滑轮602向离开吊笼7的方向推动适当的距离，使自第四换向轮组6引出的曳引媒介1下方固接的对重8与位于对重8左右的吊笼7和曳引媒介1互不干涉。本领域技术人员可以根据说明书的描述和附图选择合适的滑轮大小与滑轮间的相对距离，实现本实施方式之目的。
在一实施例中，天梁9上还设有第二立柱13，第五滑轮601固定于天梁9上，第六滑轮602固定于第二立柱13上。第二立柱13位于天梁9的下方，第五滑轮601和第六滑轮602采用可拆卸的安装方式，例如，第五滑轮601和第六滑轮602的转动轴采用U形螺栓连接。
在一实施例中，天梁9与第一立柱10或第二立柱13之间设有至少一条加强拉杆14。加强拉杆14可增强第一立柱10或第二立柱13的牢固程度。
以上所述的仅是本发明的一些实施方式。对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
