technical field

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

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.

The double-rocker arm holding rod anti-swing arm overturning pusher, wherein: the interior of each of the push cylinders is a hollow structure, the tail end is closed, and a through hole is opened in the center of the top end; one end of the push rod Pass through the through hole at the top of the push cylinder and extend into the inside of the push cylinder, and one end of the push rod protruding into the interior of the push cylinder is provided with a retaining ring uniformly protruding outward along the circumference.

The double rocker arm holding rod anti-sway arm overturning supporter, wherein: one end of the push spring is fixedly connected to the inner bottom of the tail end of the push cylinder, and the other end is matched and sleeved on the push rod extending into One end inside the push cylinder is limited by the retaining ring.

Beneficial effect:

The structure design of the double rocker arm holding pole anti-rocker arm overturning supporter of the present invention is simple and reasonable, can effectively prevent the double rocker arm holding pole from overturning, and make the double rocker arm holding pole more safe and reliable during use.

When the double rocker arm falls to the ground and holds the pole, when the tower material is in place, the double rocker arm undulates to an angle greater than 85° with the horizontal, and the anti-rocker arm overturning top of the double rocker arm arm of the present invention is installed at the mast lower flange of the upper cone section of the mast. When the rocker arm undulates to 85°, it will not be rolled to the mast due to the action of gravity. The anti-rocker arm overturning supporter of the double rocker arm of the present invention provides a rebound force to make the rocker arm bounce due to the fall of the rocker arm Back, so as to play the role of protecting the double rocker arm landing pole.

The invention can be used as a safety protection device in the process of using iron tower tools for assembling 750kV-1000kV UHV transmission lines.

Detailed ways

As shown in Figures 1 to 5, the double-rocker arm holding pole anti-rocker overturning 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 push seat 1, a push spring 2, Push rod 3 and push plate 4.

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.

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 is provided with a through hole; wherein, the same side of the tail end of the pair of push cylinders 12 is fixed with a connecting bracket 121, and the pair of push cylinders The tail ends of 12 are butted with each other and connected and fixed by connecting bracket 121 with fasteners.

Each push cylinder 12 is correspondingly equipped with a push spring 2 and a push rod 3; the push spring 2 is matched and installed inside the push cylinder 12; one end of the push rod 3 passes through the top of the push cylinder 12 The through hole extends into the inside of the push cylinder 12, and the other end protrudes toward the outside of the push cylinder 12; the end of the push rod 3 extending into the inside of the push cylinder 12 is provided with a retaining ring 31 uniformly protruding outward along the circumference; One end of the push spring 2 is fixedly connected to the inner bottom of the rear end of the push cylinder 12 , and the other end is matched and sheathed on the end of the push rod 3 protruding into the interior of the push cylinder 12 and is limited by the stop ring 31 .
