Description
Technical field
This utility model and side slope protective screen, particularly to a kind of antivibrator for rock-fall proof hazard protective net.
Background technology
In order to prevent massif instability falling rocks from people, vehicle, building etc. are caused serious harm, protection network miscellaneous
Act as " security guard " of modern society's life property safety.
Existing protection network substantially has two classes, a class to be that rigidity blocks grid, structurally by spaced apart shaped steel column with solid
Constitute due to reinforcing bar grid thereon, exist and do not possess the shortcoming slowing down rock-fall impact；Another kind of, it is mounted with antivibrator
Protection network, applies certain damping force by antivibrator to protection network, makes protection network during bearing rock-fall impact, pass through
Yielding process, consumes the energy of falling rocks, thus prevents falling rocks from passing protection network and work the mischief people, vehicle, building etc..
The most conventional antivibrator generally has steel tube component antivibrator and elastic component antivibrator two class, in order to fixed protection
The cable wire of net is fixed on column after antivibrator.
By the way of there is plastic deformation in time making steel tube component stress in steel tube component antivibrator, it is provided that the work of lasting power
With, during steel tube component deformation simultaneously, the distance at the two ends of cable wire increases because of cable wire deformation, thus in this mistake
Journey is persistently done work, plays the effect reducing falling rocks kinetic energy.The advantage of this antivibrator is simple in construction, and application is convenient, it is easy to
Safeguard, and can be reused by recovery after a deformation, but owing to its damping curve is along with tubular element deflection
Increasing, damping force starts to increase very slow, increases the most rapidly, and its damping force is difficult to control to, and the growth of damping force breaks through
The ultimate strength of protection network, causes falling rocks to pass protection network, there is also obvious deficiency for the protection of follow-up large quantities of falling rocks
Place.Meanwhile, the damping strength of this structure is the structure by steel tube component and material is determined, is bearing big impulsive force
Time, diastrophic strength is relevant with pipe thickness etc., and therefore, the antivibrator of high level generally requires more thick and heavy pipe,
Its cost can rise significantly, for this protecting screen structure huge to application amount, is the most disadvantageous.
Elastic component antivibrator utilizes the stretching of elastic component to produce damping force, absorbs rock-fall impact energy.Its advantage is
Simple in construction, easy for installation.Shortcoming is the relatively costly of elastic compression structure uncle, is also faced with and steel tube component antivibrator phase simultaneously
Same predicament, elastic component damper curve is a straight line obliquely, and elastic component is wayward, and damping force easily breaks through
Protection network ultimate strength.
Preferably the curve of damping force, is that small-sized falling rocks the most resistible to protection network does not produce effect, and only exists
After protection network supports utmost carrying ability, namely need protection network to depart from original installation position, by significantly making a concession, falling rocks is persistently done
When merit reduces its energy, just start to produce damping force acting, and the size of this damping force, it is impossible to more than the high-mechanic of protection network
The limit, in order to avoid protection network ruptures.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of antivibrator for rock-fall proof hazard protective net, with
Making antivibrator can meet the requirement of preferable damping force curve, not over protection network ultimate strength, effectively protection is different types of
Rock-fall impact, and can dismounting and change easily.
It is as follows that this utility model solves the technical scheme that its technical problem used:
Antivibrator for rock-fall proof hazard protective net of the present utility model, for the damping of rock-fall proof hazard protective net
Device, including the front end cable wire being connected with protection network and the rear end cable wire being connected with column, is characterized in that: described rear end cable wire is with outer
Cylinder formed connect, the front port of this urceolus, rear port respectively by consolidate therewith be integrated cover board of front end, rear-end plate close,
Hollow bushing and inner core it is provided with in it；Described front end cable wire is fixing with inner core after passing cover board of front end and hollow bushing to be connected,
Inner core front portion acts on the rear port of hollow bushing.
The beneficial effects of the utility model are, protection network is made in hollow bushing by inner core during rock-fall impact, and hollow bushing is swollen
Bulging deformation produces constant damping force, within the damping force of hollow bushing can be arranged on protecting wire net ultimate strength simultaneously, makes damping
Device can preferably meet the requirement of preferable damping force curve, not over protection network ultimate strength, effectively protection different types of fall
Stone impacts, safely, effectively, simple in construction, cheap, detachable.
Accompanying drawing explanation
This specification includes following two width accompanying drawings:
Fig. 1 is this utility model structural representation for the antivibrator of rock-fall proof hazard protective net；
Fig. 2 is the damping force curve control figure of multiple antivibrator.
Component shown in figure and corresponding labelling: urceolus 10, cover board of front end 10a, rear-end plate 10b, connect buckle 11,
Hollow bushing 20, inner core 21, front end cable wire 22, solid lubrication layer 23.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
With reference to Fig. 1, before the antivibrator for rock-fall proof hazard protective net of the present utility model includes being connected with protection network
End cable wire 22a and the rear end cable wire being connected with column.Described rear end cable wire is formed with urceolus 10 and is connected, the front end of this urceolus 10
Mouth, rear port by consolidating cover board of front end 10a, the rear-end plate 10b closing being integrated therewith, are provided with hollow bushing respectively in it
20 and inner core 21.Described front end cable wire 22 is fixing with inner core 21 after passing cover board of front end 10a and hollow bushing 20 to be connected, inner core 21
Front portion acts on the rear port of hollow bushing 20.When protection network is by rock-fall impact, inner core 21 makees in hollow bushing 20, hollow
Sleeve pipe 20 dilatancy produces constant damping force, simultaneously the damping force of hollow bushing 20 can be arranged on protecting wire net ultimate strength it
In, make antivibrator can preferably meet the requirement of preferable damping force curve, not over protection network ultimate strength.
With reference to Fig. 1, it is ensured that stablizing of damping force, described inner core 21 is anterior tapered, and described hollow bushing 20 inwall is with front
Filling solid lubrication layer 23 between end cable wire 22.
