An anti-dumping mechanical device and method for an inner suspension stay wire holding rod

Abstract

An anti-dumping mechanical device and method for an inner suspension stay wire holding a pole, mainly including a trigger mechanism and an anti-dumping mechanism; the trigger mechanism includes a trigger box, the trigger box is installed on the pole, and a channel is arranged in the trigger box, and the middle of the channel is low, The outer side is high, the channel is located at the lower part to install the trigger ball, and the channel is located at the higher end to install the groove, and the pressure sensor is installed in the groove; the anti-dumping mechanism includes multiple supports, each supporting the upper part and the longitudinal beam holding the pole The first electromagnet and the second electromagnet are installed on the hinged and lower part; when the first electromagnet is powered on and the second electromagnet is powered off, the first electromagnet is adsorbed and fixed to the pole; when the first electromagnet is powered off, the second electromagnet When the electromagnet is energized, the strong spring will expand the support and push it against the iron tower. The invention provides an anti-dumping mechanical device and method for an inner suspension stay wire holding rod, which prevents the inner suspension stay wire holding rod from tipping over, ensures that the tower body is not damaged, and construction personnel are not injured.

Description

technical field

[0001] The invention relates to the field of iron tower erection construction, in particular to an anti-dumping mechanical device and method for an inner suspension stay wire holding pole. Background technique

[0002] When the power transmission tower is erected, the tower material is often lifted by the inner suspension stay wire holding rod, and the inner suspension stay wire holding rod is generally supported and fixed by the bottom support rope and the top support rope. Iron towers are generally erected in remote mountainous areas, and wind power in mountainous areas will cause the poles to shake. When the wind is too strong, two situations may occur, one is that the inner suspension stay wire holding rod is tilted at 15 degrees and then falls to the tower body, and the other is that the support rope breaks and the inner suspension stay wire holding rod falls. For example, in 2017, during the erection of a ±500kV direct current transmission tower, a con...

Embodiment Construction

[0042] Such as figure 1 As shown in FIG. 1 , an anti-dumping mechanical device with an inner suspension stay wire holding rod includes a trigger mechanism and an anti-dumping mechanism.

[0043] Such as Figure 2-7 As shown, the trigger mechanism includes a trigger box 2, the bottom of the trigger box 2 is fixed with the magnetic upper layer 3 by welding, the magnetic upper layer 3 is magnetically fixed with the magnetic lower layer 4, and the magnetic lower layer 4 is welded with the connecting plate 7 fixed. There are 2 connecting plates 7 in a cross-shaped distribution. The connecting plate 7 is processed from an aluminum plate, and an aluminum plate with high hardness and not easy to break is selected for use. There are four pole fixing holes 8 on both sides of each connecting plate 7 , and the U-shaped ring 11 passes through the pole fixing holes 8 of the aluminum plate 7 and is fixed with the pole 5 . The bolt 9 and the nut 10 pass through the U-shaped ring connectin...
