Abstract

The invention discloses an installation steel wire rope structure for a movable arm tower crane and belongs to the field of installation structures of steel wire ropes on movable arm tower cranes. The installation steel wire rope structure comprises an installation steel wire rope arranged between a boom and a tower top, a pulley block (4) used for changing the work direction of the steel wire rope, and a balance weight set (5) used for preventing the steel wire rope from being concaved downwards. One end of the installation steel wire rope is fixed to the boom, and the other end of the installation steel wire rope is connected with the balance weight set. A tower top supporting rod (6) is arranged on the tower top. The pulley block (4) is installed in the tower top. The end, connected with the balance weight set (5), of the installation steel wire rope bypasses the pulley block (4) from the upper side of the pulley block (4), and then the rear end of the installation steel wire rope is connected with the balance weight set (5). The tower top supporting rod (6) is used as a guide rail of the balance weight movement for the balance weight set (5). The guide rail limits the balance weight movement.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below by accompanying drawing and embodiment, the present invention is further elaborated.But should be appreciated that, specific embodiment described herein, only in order to explain the present invention, is not limited to scope of the present invention.
As shown in Figure 3 and Figure 4, a kind of movable arm tower crane installs steel cord structure, comprise and be arranged on installation steel rope 2 between crane arm 1 and tower top 3, for changing the assembly pulley 4 of steel rope operating direction and the weight set 5 for avoiding steel rope recessed, one end of described installation steel rope 2 is fixed on crane arm 1, and the other end is connected with weight set 5;
Described tower top 3 is provided with tower top strut 6, it is inner that described assembly pulley 4 is arranged on tower top 3, after assembly pulley 4 is walked around in one end that described installation steel rope 2 is connected with weight set 5 on the upside of assembly pulley 4, end is connected with weight set 5, described weight set 5 is using tower top strut 6 as the guide rail of counterweight movement, the spacing counterweight movement of this guide rail, when steel rope rises or decline, weight set 5 is moved along tower top strut 6.
As the improvement of embodiment, described tower top strut 6 adopts the orthogonal strut perpendicular to horizontal surface, can effectively carry out spacing to weight set 5, when weight set 5 moves along the guide rail that orthogonal strut is formed, rely on gravity tensioning to install steel rope, energy actv. ensures the effect of tension.
