The invention discloses a tower crane standard knot convenient to transport, disassemble and assemble. The tower crane standard knot comprises vertical rods, connecting mechanisms and fixing mechanisms, wherein connecting holes are formed in the vertical rods, cross rods are connected to the inner walls of the connecting holes, sealing plates are connected to the outer walls of the cross rods, andconnecting bolts penetrating through the connecting holes to be connected with the cross rods are arranged on the outer walls of the connecting holes. By arranging the connecting mechanisms, the cross rods align at the connecting holes, the two ends of the cross rods are clamped into the connecting holes in the two vertical rods correspondingly, positioning columns are clamped into the inner walls of positioning holes in the process, and after the two ends of the cross rods are completely clamped into the inner walls of the connecting holes, the connecting bolts are screwed into the inner walls of the connecting holes; and when the connecting bolts drive studs to make contact with embedded threaded sleeves, the connecting bolts continue to be rotated, at the moment, the studs enter the inner walls of the embedded threaded sleeves under the action of internal threads and external threads, thus, the contact area of the connecting bolts and the cross rods is increased, and connecting force is improved.
本发明公开了一种便于运输拆装的塔机标准节,包括竖杆、连接机构与固定机构,所述竖杆的内部设置有连接孔,所述连接孔的内壁连接有横杆,所述横杆的外壁连接有封板,所述连接孔的外壁设置有贯穿连接孔与横杆相连的连接螺栓。本发明通过设置连接机构,通过将横杆对准连接孔,并将横杆的两端分别卡入两个竖杆内的连接孔中,在此过程中定位柱卡入定位孔的内壁,当横杆的两端完全卡入连接孔的内壁后,再将连接螺栓旋入连接孔的内壁,当连接螺栓带动螺柱与内嵌螺套接触时,继续转动连接螺栓,此时螺柱在内、外螺纹的作用下进入内嵌螺套的内壁,从而增大连接螺栓与横杆的接触面积,提高连接力。
