Certainly the problems in background technique.
To achieve the above object, the utility model provides the following technical solutions: one kind is secondary for flying tower balladeur train downlink
Protective device including oil buffer ontology and is mounted on the outer shield of oil buffer outer body, and outer shield position is hollow
The second buffer spring is arranged in tubular structure, the inside of outer shield, and the cylinder part inner sleeve of oil buffer ontology is slow second
Rush the inside of spring, be socketed with the first buffer spring on the outside of the piston rod portion of oil buffer ontology, the first buffer spring and
Cover board is provided between second buffer spring, the top of the first buffer spring is provided with bearing plate, and it is slow that bearing plate is fixed on oil pressure
Rush the piston rod top end of device ontology.
As the utility model a preferred technical solution, through-hole is provided at the center of cover board, cover board is located at outer shield
The inside of cover is at upper port.
As the utility model a preferred technical solution, the outer diameter of cover board and the internal diameter of outer shield are identical and described
The sliding opposite with the outer shield inner wall of the lateral surface of cover board.
As the utility model a preferred technical solution, the diameter of through-hole is greater than the hydraulic cylinder of oil buffer ontology
Position outer diameter.
As the utility model a preferred technical solution, the diameter of bearing plate is not less than the outer diameter of outer shield.
As the utility model a preferred technical solution, the height of outer shield is greater than the oil buffer ontology
Hydraulic cylinder position height, and difference in height is not less than 1/5th of the stroke distances of the first buffer spring.
Compared with prior art, the utility model has the beneficial effects that by increasing in the external of oil buffer ontology
Secondary protector, when balladeur train impacts oil buffer ontology, the first buffer spring, the second buffer spring and oleo cushion
Device ontology absorbs impact power together, undertakes a part of impact force, improves the general safety performance of equipment；Protective cover, bearing plate and
The dimensions of oil buffer ontology hydraulic cylinder, has reserved the surplus of oil buffer ontology 20%, and overload is avoided to use, and increases
Add service life, prevents detonation failure from bigger loss occur；In the failure of oil buffer ontology, secondary protector can also
With work；Structure is simple, easy for installation, maintenance convenient for safeguarding.
Detailed description of the invention
Fig. 1 is the general assembly structural schematic diagram of the utility model.
In figure: 1- oil buffer ontology；2- outer shield；3- cover board；4- bearing plate；The first buffer spring of 5-；6- second
Buffer spring；7- through-hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
Referring to Fig. 1, the utility model provides a kind of technical solution: one kind is filled for flying tower balladeur train downlink second protection
It sets, including oil buffer ontology 1 and the outer shield 2 being mounted on the outside of oil buffer ontology 1,2 hollow tubes of outer shield
The second buffer spring 6 is arranged in shape structure, the inside of outer shield 2, and the cylinder part inner sleeve of oil buffer ontology 1 is slow second
The inside of spring 6 is rushed, is socketed with the first buffer spring 5, the first buffer spring on the outside of the piston rod portion of oil buffer ontology 1
5 and second are provided with cover board 3 between buffer spring 6, and the top of the first buffer spring 5 is provided with bearing plate 4, and bearing plate 4 is fixed
In the piston rod top end of oil buffer ontology 1.
In the present embodiment, through-hole 7 is provided at the center of cover board 3, cover board 3 is located at the inside of outer shield 2 close to upper port
Place.
In the present embodiment, the outer diameter of cover board 3 is identical as the internal diameter of outer shield 2, and the lateral surface of the cover board 3 and described outer
2 inner wall of shield is opposite to be slided.
In the present embodiment, the diameter of through-hole 7 is greater than the hydraulic cylinder position outer diameter of oil buffer ontology 1.First buffering elastic
Spring 5 and the second buffer spring 6 guarantee the normal sliding of cover board 3 when compressing.
In the present embodiment, the diameter of bearing plate 4 is not less than the outer diameter of outer shield 2.
In the present embodiment, the height of outer shield 2 is greater than the hydraulic cylinder position height of the oil buffer ontology 1, and high
