Protect electric pole；When the 5th connection square moves down；5th connection square, which will drive, pushes disk to move down；It pushes
Disk moves down the liquid that can be squeezed in first hydraulic cylinder；So that the fluid pressure in first hydraulic cylinder becomes larger.In the present invention
When pedestal disk is just swung around opposite rotation axis；It is located at the first connecting rod and first in same direction with the rotation axis
Slight oscillatory can occur for telescopic rod；But the swing of first connecting rod and the first telescopic rod is in first connecting rod and the first telescopic rod
Under the action of the spherical hinge of composition and the first telescopic rod are flexible；First telescopic rod would not drive the second telescopic rod to swing.
In the present invention when the first telescopic rod and the second telescopic rod are swung；Since the impact force of electric pole transmitting is larger
So reaction force of the annular flexural pivot shell when the first telescopic rod is swung with the second telescopic rod by flexural pivot is also relatively large；
Annular flexural pivot shell thus be may cause by a stronger upward pulling force；Damage annular flexural pivot shell；So that annular flexural pivot shell
Lose hinged effect；So the lower end of spacing block is fixed on soil horizon in the present invention；The upper end of spacing block is mounted on concrete layer
Lower end；Guide groove there are two symmetrically being opened on the inner wall of second hydraulic cylinder；The upper end of second hydraulic cylinder is mounted on concrete layer lower end
And it is located on spacing block in the first square groove；Symmetrically there are two guide blocks for installation on the periphery of hydraulic inner prop upper end；In hydraulic
Second fixture block groove there are two symmetrically being opened on the periphery of column lower end；The upper end of hydraulic inner prop passes through two guide blocks and two guide grooves
Be fitted in second hydraulic cylinder；Hydraulic inner prop lower end is located at the two of in the round hole on spacing block and hydraulic inner prop lower end
A second fixture block groove cooperates with two the second fixture blocks；First fixture block groove there are two symmetrically being opened on the periphery of pouring weight；Pouring weight position
Two the first fixture block grooves in the round hole on spacing block and on pouring weight cooperate with two the first fixture blocks；When in first hydraulic cylinder
Fluid pressure become larger and when pressure reaches the limiting value of pressure export；Liquid in first hydraulic cylinder will pass through hydraulic tube stream
Enter in second hydraulic cylinder；The liquid flowed into second hydraulic cylinder just will push hydraulic inner prop；Give hydraulic inner prop one downward pressure
Power；When the pressure that hydraulic inner prop is subject to is greater than thrust of two the 4th springs to the second fixture block；Hydraulic inner prop will be to moving down
It is dynamic；Hydraulic inner prop moves down will be to one downward thrust of pouring weight；When the thrust that pouring weight is subject to is greater than two third springs
When to the thrust of the first fixture block；Pouring weight will be moved down along round hole；So that pouring weight is pounded to annular flexural pivot shell；Strengthen ring
The stability of shape flexural pivot shell；The effect of first hydraulic cylinder and second hydraulic cylinder that the present invention designs is by hydraulic inner prop to pouring weight
Add a thrust；So that the initial velocity of pouring weight becomes faster；Reduce the time that pouring weight moves down；It ensure that annular flexural pivot shell
It can be consolidated in time.In the present invention in buffer gear initialization；Annular ball is buffered by the elastic force of second spring
The upward pulling force that hinge shell is subject to；Guarantee annular flexural pivot shell by pouring weight when the upward pulling force that annular flexural pivot shell is subject to is larger
Stability；Its effect of eight swing mechanisms that the present invention designs is that the rum point being subject to when electric pole is located at two neighboring buffer
When among structure；A swing mechanism corresponding in rum point opposite direction can play its work in eight swing mechanisms
With；Buffer gear is gone on smoothly.
When the electric pole that people are designed using the present invention；When electric pole is hit；It is not easy if electric pole is harder
It destroys；Electric pole just will drive pedestal disk and swing；The swing of pedestal disk will make in eight swing mechanisms wherein phase
Swinging block run-off the straight in a corresponding swing mechanism；Two limited blocks in swinging fast tilting procedure on swinging block are just
It can be contacted with the rotation axis in rotational support；So that two limited blocks are to limiting slot medial movement；When two limited blocks are complete
When portion is moved in corresponding limiting slot；Rotation axis will be stuck in nested troughs；Two limited blocks are corresponding first at this time
Limiting slot is moved out under the action of spring；Two limited blocks and nested troughs form a closing shaft set；Pass through two limited blocks
A revolute pair is combined into matching for rotation axis with the shaft set of nested troughs composition；It will be around by the rotation sub-mount disk
Opposite rotation axis is swung；Pedestal disk, which is swung, just will drive the first connecting rod that is in opposite direction with rotation axis to moving up
It is dynamic；First connecting rod drives one end on the first telescopic rod close to first connecting rod to be swung up by spherical hinge；First is flexible
Bar swings will make by the spherical hinge of flexural pivot and annular flexural pivot shell composition on the second telescopic rod far from the first telescopic rod one
It holds to lower swing；One end on second telescopic rod far from the first telescopic rod will drive the 5th connection square to move downwards to lower swing
It is dynamic；The impact force that electric pole is subject to by a series of transmissions in the present invention by buffer gear is sequentially delivered to ground；To anti-
Electric pole is stopped when being hit, impact force damages the ground on the downside of electric pole；And then protect electric pole.
