[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0019] Example 1

[0020] See also Figure 1 and Figure 4The π-type wind turbine hybrid tower safety belt suspension device includes a top frame 1, a side frame 2, a universal wheel 3, a walking wheel 4 and a hanging ear 5. The top frame 1 includes a cross bar 11 and a longitudinal bar 12. A plurality of longitudinal bars 12 are connected between two cross bars 11 at intervals. A plurality of universal wheels 3 are respectively installed at the bottom of the longitudinal bars 12. The side frame 2 includes a vertical bar 21 and a connecting rod 22. The vertical bar 21 is vertically connected to both ends of the cross bar 11. A plurality of connecting rods 22 are connected between two vertical bars 21 on the same side. A plurality of walking wheels 4 are installed on the vertical bar 21. The walking direction of the walking wheel 4 is set to be consistent with the length direction of the side frame 2. The hanging ear 5 is fixed on the longitudinal bar 12. An oblique bar 23 is connected at the connecting angle between the cross bar 11 and the vertical bar 21 to enhance the stability of the structure.

[0021] In this embodiment, the top frame 1 and the side frame 2 are both made of stainless steel pipes, which are welded together, and the universal wheels 3 and the walking wheels 4 are made of ABS wear-resistant pulleys.

[0022] Instructions for use: hoist the fixed point device above the fan mixing tower, and insert it into the tower body of the fan mixing tower from top to bottom. At this time, the top frame 1 is located above the tower body, the universal wheel 3 is in contact with the top surface of the tower body, and the two side frames 2 are located on both sides of the tower body, and the walking wheel 4 is in contact with the two side surfaces of the tower body. The device can be fixed on the tower body through the cooperation of the top frame 1, the side frame 2 and the tower body, and the device can be moved on the tower body through the cooperation of the universal wheel 3, the walking wheel 4 and the tower body. The staff can hang the safety belt on the hanging ear 5, thereby playing a risk control role in high-altitude operations during the on-site hanging and slinging process.
