一种组立杆塔用抱杆
摘要：
本发明公开了一种组立杆塔用抱杆，包括主杆和延长杆，所述主杆上设置有底座与连接座，所述底座上设置有下轴套与下拉线孔，所述下轴套焊接于底座顶部，下轴套螺纹连接于主杆底部，所述下拉线孔开设于底座边角上，所述连接座顶部与底部对称焊接有中轴套，所述中轴套底部螺纹连接于主杆顶部，所述延长杆螺纹连接于中轴套顶部，延长杆上设置有顶座，所述顶座上设置有上轴套、上拉线孔、主滑轮与复滑轮，所述上轴套焊接于顶座底部，上轴套螺纹连接于延长杆顶部，所述上拉线孔开设于顶座边角上，所述主滑轮焊接于顶座顶部，所述复滑轮通过螺栓连接于顶座两端。本发明可轻松对杆塔进行阶梯式搭建，有效提高了工作效率。
摘要（英）：

The invention discloses a derrick for an assembled pole tower, which comprises a main pole and a prolonged pole. The main pole is provided with a base and a connecting seat, the base is provided witha lower shaft sleeve and lower stay wire holes, the lower shaft sleeve is welded on the top of the base, the lower shaft sleeve is in threaded connection on the bottom of the main pole, the lower staywire holes are formed in the edge corners of the base, a middle shaft sleeve is symmetrically welded on the top and bottom of the connecting seat, the bottom of the middle shaft sleeve is in threadedconnection on the top of the main pole, the prolonged pole is in threaded connection on the top of the middle shaft sleeve, the prolonged pole is provided with a top seat, the top seat is provided with an upper shaft sleeve, upper stay wire holes, a main pulley and a block pulley, the upper shaft sleeve is welded on the bottom of the top seat, the upper sleeve shaft is in threaded connection on the top of the prolonged pole, the upper stay wire holes are formed in the edge corners of the top seat, the main pulley is welded on the top of the top seat, and the block pulley is connected on bothends of the top seat by bolts. The derrick can be used for stepped construction of the pole tower easily, and the working efficiency is effectively improved.
