The invention discloses a municipal engineering drainage pipeline installation lifting appliance which comprises a horizontal plate and two supporting frames fixed to the bottom of the horizontal plate, two reinforcing rods are fixed to the top and the bottom of the horizontal plate respectively, a crane is fixed to the tops of the reinforcing rods, a steel cable is connected to the crane, and a plurality of fixing rings and protection rings are fixed to the middle of the horizontal plate in a penetrating mode. Threaded rods are fixed to the middles of the multiple fixing rings in a penetrating mode, the bottoms of the threaded rods are sleeved with upper threaded rings and lower threaded rings in a threaded mode, stabilizing pipes are fixed to the middles of the protection rings in a penetrating mode, the fixing rings are fixed to the bottoms of the stabilizing pipes in an embedded mode, and a lifting plate is fixed to the fixing rings in an embedded mode. The steel cable spirally penetrates through the stabilizing pipe, the steel cable and the inner wall of the stabilizing pipe form linear contact, the linear contact between the steel cable and the stabilizing pipe is spiral, it is ensured that friction force between the steel cable and the stabilizing pipe is sufficient, the steel cable stably moves in the middle of the stabilizing pipe, and it is ensured that a workpiece at the bottom of the steel cable stably moves up and down; and the drainage pipeline can be stably lifted or put down.
本发明公开了一种市政工程用排水管道安装吊具,包括水平板以及其底部固定的两个支撑架,水平板的顶部和底部均固定有两个加固杆,加固杆的顶部固定有吊机,吊机上连接有钢索,水平板的中间贯穿固定有多个固定环和防护圈,多个固定环的中间均贯穿固定有螺纹杆,螺纹杆的底部均螺纹套接有上螺环和下螺环,防护圈的中间贯穿固定有稳定管,稳定管的底部嵌套固定有固定圈,固定圈上嵌套固定有升降板。本发明中的钢索螺旋穿过在稳定管中,钢索与稳定管的内壁形成线接触,钢索与稳定管之间的线接触呈螺旋状,确保钢索与稳定管之间的摩擦力足够,使钢索平稳的在稳定管的中间移动,确保钢索底部的工件平稳的上下移动,可以平稳的将排水管道吊起或放下。
