The invention relates to the field of tower cranes, and discloses a tower crane attachment rack control rod which can be fixed in a universal mode and is safe and reliable. According to the technical scheme, the tower crane attachment rack control rod comprises a pull rod, an ear plate and an embedded part, wherein the embedded part comprises a universal fixing device; the pull rod is connected with the universal fixing device through the ear plate. By virtue of the universal fixing device, the tower crane attachment rack control rod is flexible and convenient to use; by splicing and welding two steel channels, the structure strength is improved, and the accident rate is lowered; by virtue of the embedded part, the installation efficiency is improved. The tower crane attachment rack control rod is simple in structure, convenient to use, install and weld, safe, reliable and capable of saving labor cost and time cost greatly.
Description
technical field [0001] The invention relates to the field of tower cranes, in particular to an adjusting pull rod for an attachment frame of a tower crane. Background technique [0002] The tower crane attachment frame adjustment rod in the prior art is welded by the rod and the lug plate, and the mounting hole at the other end of the ear plate is connected with the workpiece to be fixed; the pull rod is welded by two channel steel and a small steel plate The rhombus-shaped tie rod has a structural strength that cannot meet its strength standard, and there is a great safety risk; while the ear plate can only be fixed at a certain position, the length and direction cannot be adjusted, and it is easy to shift, which is inconvenient to use and has low stability ; Labor costs, installation costs, transportation costs are high, and safety risks are high. There is an urgent need for a universally adjustable and fixed, safe and reliable crane attachment frame adjustment pull rod. ...
