[0002] As our country enters the era of UHV power grids, UHV power transmission projects have been intensively started in recent years. The important link is the construction of UHV iron towers. During the ups and downs, when the angle between the rocker arm and the horizontal exceeds 85°, due to the gravity of the rocker arm, the rocker arm will instantly deflect to the mast. If the two rocker arms are unbalanced, the entire mast and pole will overturn, and even accidents will occur. Or it may happen that the rocker arm leans against the mast, due to the effect of gravity, it is not easy to adjust the rocker arm to the angle position with the undulating rope and lifting rope

Embodiment Construction
[0021] Such as Figures 1 to 5 As shown, the double rocker arm holding pole anti-sway arm tipping supporter of the present invention is matched and installed on the lower flange 6 of the upper cone section 5 of the mast, which includes a pushing seat 1, a pushing spring 2, a pushing rod 3 and a Push plate 4.
[0022] The push seat 1 has a pair and is symmetrically installed on the lower flange 6 of the upper cone section 5 of the mast. A pair of fixed plates 11 are symmetrically fixed on the bottoms of both ends of the pair of push seats 1; the pair of fixed plates 11 The opposite sides of the lower flange 6 fixed on the upper cone section 5 are fastened by fasteners.
[0023] Each push seat 1 is connected by a pair of push cylinders 12, and the tail ends of the pair of push cylinders 12 are butted and fixed so that each push seat 1 forms a two-way push seat structure; The inside of the cylinder 12 is a hollow structure, the tail end is closed, and the center of the top end ...

The invention relates to a rocker arm overturning prevention jacking and supporting device for a double-rocker-arm derrick. The rocker arm overturning prevention jacking and supporting device for thedouble-rocker-arm derrick is arranged on a lower flange of an upper cone section of a mast, and comprises a jacking and pushing seat, jacking and pushing springs, jacking and pushing rods and jackingand pushing plates, wherein the jacking and pushing seat is horizontally and fixedly arranged on the lower flange of the upper cone section of the mast; the jacking and pushing seat is of a two-way jacking and pushing seat structure and is formed by connecting a pair of jacking and pushing tubes; the jacking and pushing spring is arranged in each jacking and pushing tube; one end of each jacking and pushing rod extends into the corresponding jacking and pushing tube and is matched and connected with the corresponding jacking and pushing spring; the other end of each jacking and pushing rod extends out towards the outer side of the jacking and pushing tube; and the end part of each jacking and pushing rod is provided with the corresponding jacking and pushing plate. The rocker arm overturning prevention jacking and supporting device for the double-rocker-arm derrick has the advantages that the structural design is simple and reasonable; and the overturning of the double-rocker-arm derrick can be effectively prevented, so that the safety and the reliability of the double-rocker-arm derrick in the use process are higher.
Description
technical field [0001] The invention relates to the technical field of UHV power transmission engineering, in particular to a double rocker arm holding pole anti-rocker arm overturning supporter. Background technique [0002] As my country enters the era of UHV power grids, UHV power transmission projects have been intensively started in recent years, and the important link is the construction of UHV iron towers. During the ups and downs, when the angle between the rocker arm and the horizontal exceeds 85°, due to the gravity of the rocker arm, the rocker arm will instantly deflect to the mast. If the two rocker arms are unbalanced, the entire mast and pole will overturn, and even accidents will occur. Or it may occur that the rocker arm leans against the mast, and due to the effect of gravity, it is not easy to adjust the rocker arm to the angled position with the undulating rope and the lifting rope.
