Description
Technical field
The utility model relates to electric power electric field, in particular to lightning rod on a kind of framework.
Background technique
Lightning rod is all made of round steel tube section on existing substation's major part framework, and lightning rod is very high, average height
20m, up to 30 meters of part, lightning rod top displacement is fairly obvious, in order to avoid site welding, lightning rod and truss column in design
Top use flanged joint, this results in the fatigue rupture of bolt under the action of frequent wind load, at the same may cause due to
Bolt destruction causes lightning rod to fall, and causes safety accident, and domestic existing Engineering Projects, suffers heavy losses.Domestic 500kV
Substation framework generallys use steel pipe inverted Y-shaped column structure outside 330kV, 220kV and 1 room 10kV, and the lightning rod of top setting is all
Using the structural shape of single steel pipe, such structural shape is easy to appear larger swing at the top of lightning rod under the action of strong wind,
Under the action of long-term, easily there is fatigue phenomenon in the steel pipe of lightning rod and the bolt of connection.Eventually lead to the intensity drop of lightning rod
Low and broken ring.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of fatigue strength that can be improved lightning rod, wind loading ratings
By force, lightning rod on the high framework of bearing capacity.
In order to solve the above-mentioned technical problem, the embodiment of the utility model are as follows:
Lightning rod on a kind of framework, including herringbone column holder, the herringbone column holder cochain is connected to first flange disk, described
It is connected with second flange disk on first flange disk, lightning rod main body, the lightning rod main body are connected on the second flange disk
Top be provided with lightning rod needle point；The lightning rod main body includes steel pipe, and placed longitudinally more are provided in the steel pipe
Reinforcing bar is provided with several outer stirrups on the reinforcing bar, is filled with mixed mud in the steel pipe；The steel pipe bottom is connected to second
On ring flange.
Preferably, the lightning rod main body by the second flange disk and the first flange disk using bolt with it is described
The connection of herringbone column holder.
Preferably, the lightning rod needle point is conical.
Preferably, the position on reinforcing bar described in the outer stirrup is uniformly distributed.
Compared with prior art, the utility model has the following beneficial effects:
Lightning rod on a kind of framework provided by the utility model can play one to total using herringbone column holder
A stable effect, improves the bearing capacity of the lightning rod；It is connected to ring flange on herringbone column holder, reconnects lightning rod
Main body reduces the length of lightning rod main body, the comprehensive wind loading rating for improving the lightning rod on the whole；Lightning rod main body includes
Steel pipe is provided with longitudinally disposed reinforcing bar in steel pipe, is also provided with outer stirrup on reinforcing bar, and then filling again mixed mud mentions
The high fatigue strength of the lightning rod is connected to ring flange at the top of herringbone column, can prevent separating for herringbone column, cause to take shelter from the thunder
The damage of needle.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of lightning rod on the framework of the utility model embodiment；
Fig. 2 is the transverse sectional view of the lightning rod main body of the utility model embodiment.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.
It should be noted that being used to help understand the utility model for the explanation of these embodiments, but not
Constitute the restriction to the utility model.In addition, technology involved in the various embodiments of the present invention described below
Feature can be combined with each other as long as they do not conflict with each other.
Implementation column 1
It please refers to shown in Fig. 1, Fig. 2, lightning rod on a kind of framework provided by the utility model, including herringbone column holder 1, phase
For existing single steel pipe structure, there is bigger rigidity, be displaced more caused by lightning rod needle point 4 under the action of strong wind
It is small.1 cochain of herringbone column holder is connected to first flange disk 2, first flange disk 2 to herringbone column holder 1 play the role of one it is fixed, mention
The high connection reliability of herringbone column holder 1, prevents herringbone column holder 1 to be detached from, security performance is high.It is connected on first flange disk 2
There is second flange disk 5, lightning rod main body 3 is connected on second flange disk 5, the top of lightning rod main body 3 is provided with lightning rod needle
Point 4；Lightning rod main body 3 includes steel pipe 6, is provided with more placed longitudinally reinforcing bars 8 in steel pipe 6, is provided on reinforcing bar 8 several outer
Stirrup 7 is filled with mixed mud 9 in steel pipe 6, improves the fatigue strength of the lightning rod；6 bottom of steel pipe is connected to second flange disk
On 5.
Lightning rod main body 3 is connect using bolt with herringbone column holder 1 by second flange disk 5 and first flange disk 2, is solved
The problem of leading to the strength reduction of lightning rod main body 3 because of welding.
Lightning rod needle point 4 is conical, under the effect by wind loads, can divide the load of strong wind
Solution, and forced area is reduced, improve the service life of lightning rod.
Position of the outer stirrup 7 on reinforcing bar 8 is uniformly distributed, so that 8 each sections of reinforcing bar of stress condition is consistent, it is strong to improve fatigue
Degree.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
