Because the tower body is very high, the cable runs through the whole tower body from top to bottom again, leads to the dead weight of cable can be very heavy, needs to use the cable clamp splice to fix thick and heavy cable segmentation in the fan tower. At present, the cable is mainly fixed with the fan tower frame through the cable clamping block in the following two ways: firstly, welding a mounting plate on the wall of the tower body, and fixedly connecting a cable clamping block with the mounting plate; and secondly, adding a cable bridge on the ladder stand or other vertical fixing pieces, and fixedly connecting the cable clamping block with the cable bridge.
However, welding the mounting plate on the tower inner cylinder wall may reduce the fatigue level of the tower cylinder wall, i.e. under the same conditions, the tower cylinder wall with the mounting plate welded may have a greater probability of being thicker than the tower cylinder wall without the mounting plate welded. Due to the dense distribution of the cable clamping blocks, each section of the tower body can be affected, and therefore, the increased material cost is large. Although adding cable bridges to ladders or other vertical fixtures helps to reduce the material cost of the tower body, the following disadvantages exist: firstly, a cable bridge is often required to occupy a central position of a tower body as an additional device, large cabinet equipment is usually arranged at the bottom of the tower body, and the diameter of the top of the tower body is sharply reduced, so that the cable bridge greatly influences the layout of the equipment at the top and the bottom of the tower body; secondly, the cable bridge and the cable fixed on the cable bridge through the cable clamping block bring a heavy burden to the ladder stand and the platform.
