Technical field
The utility model belongs to side slope protective screen technical field, and the repeatable of more particularly to a kind of side slope protective screen utilizes
Friction energy dissipation device.
Background technology
Protection network is to be used to prevent the disasters such as Falling Rocks, landslide from destroying protected object, and it is divided into active protecting net, quilt
Dynamic protection network and leading type protection network.Wherein energy dissipator is the main energy dissipation piece as current protecting net system, and its effect is
When protecting net system is impacted, impact kinetic energy is passed to by energy dissipator by draw cord system, energy dissipator passes through deformation
Or impact kinetic energy is changed into friction interior energy or potential energy of deformation by the mode such as friction, so as to have the function that to absorb impact kinetic energy.
At present, for pressure-reducing ring, it has the drawback that the energy dissipator that protection network generally uses：Energy dissipator can only make
With once, be difficult to reuse, i.e., in protecting net system after once intercepting, the energy dissipator is just as irreversible deformation
And can not reuse, and replacing during reparation protecting net system to the part is relatively difficult.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of repeatable protection network friction energy dissipation device utilized,
Be intended to by friction and deformation eliminate protection network when bearing falling rocks or landslide etc. and impacting supporting rope, draw in the system such as anchor line by
Impact energy, the friction interior energy and the elastic potential energy of steel disc deformation impulsive force being converted between steel disc, solve existing energy dissipating dress
Put energy release after can not reuse the drawbacks of.
In order to solve the above-mentioned technical problem, the utility model is accomplished by the following way：
The repeatable protection network friction energy dissipation device utilized, including pressing device, two arc spring plates, shackle I and unload
II is detained, the pressing device includes upper and lower two pressing plates, bolt nut structure and spring shim, and bolt nut structure is through up and down
After two pressing plates, with the common locking pressure plate of spring shim, up and down two pressing plate of the arc spring plate mounted on top in pressing device
Between, and fixed before and after being carried out by bolt nut structure, the steel plate that the arc spring plate is upturned for one end, the shackle
I and shackle II is respectively at the heteropleural port of different pressing plates.
Further, in order to protect shackle I, shackle II and latch plate bonding strength, and position-limiting action can be played,
The utility model is additionally provided with reinforcing plate, and the reinforcing plate is located at the end of arc spring plate, and by bolt and shackle I, unload
Button II is connected.
Further, in order to ensure as the good contact between latch plate and between latch plate and pressing plate, the arc bullet
Spring plank has carried out edge chamfer processing.
In pressing device, in order to avoid bolt nut structure is caused failure by shear by excessive tangential stress, this
Pressing plate in the pressing device of patent uses U-shaped pressure plate structure.
In addition, to improve stress condition of the pressing plate with steel spring plate in relative slide, this patent is by pressing device
Upper and lower two pressing plate is pressing plate of the both ends with arc.
Compared with prior art, the utility model has the advantage that：
The present apparatus eliminates protection network supporting rope, drawing anchor line etc. when bearing falling rocks or landslide etc. and impacting by friction and deformation
The impact energy being subject in system, two blocks of arc spring plates occur relative slip and deformation, impact kinetic energy are converted into friction
Energy dissipating purpose can be reached with deformation elastic potential energy；After energy discharges, it is only necessary to exchange the position of drawstring, that is, reach weight
The purpose utilized again, solve the drawbacks of existing energy dissipator can not reuse after energy release, and relatively existing disappear of constructing
Energy device is more convenient.

Embodiment
Specific embodiment of the present utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, the protection network friction energy dissipation device utilized, including 10, two arc bullets of pressing device are repeated
Spring plank 20, shackle I 31 and shackle II 32, the pressing device include upper and lower two pressing plate 11, bolt nut structure 12 and spring
Pad 13, after bolt nut structure runs through upper and lower two pressing plate, and the common locking pressure plate of spring shim, above and below the arc spring plate
Between two pressing plates up and down for overlaying pressing device, and fixed before and after being carried out by bolt nut structure, the arc spring plate is
The steel plate that one end is upturned, the shackle I and shackle II are respectively at the heteropleural port of different pressing plates, while in order to protect
