Description
Technical field
The invention belongs to technical field of safety protection, and in particular to a kind of passive flexible protective for being used to intercept Falling Rocks
In system, the energy dissipator of impact load in steel wire rope is absorbed and slowed down.
Background technology
Passive flexible protection systems are mainly by interception component（Wire rope net and ring network）, fixed system（Anchor pole, draw anchor
Rope, pedestal, steel column and supporting rope）Formed with energy dissipator, its anti-rock-fall impact ability is mainly by interception component and energy dissipator
Elastic-plastic deformation provide, energy dissipator to it is whole passively flexible protection systems also there is overload protection, therefore, energy dissipating
The stability of device is particularly important for passive flexible protection systems.
Chinese patent literature CN205576943U discloses one kind on the 14th in September in 2016 and is applied to passive soft protecting net
New energy dissipation piece, it is by the first steel wire rope, the second steel wire rope, the first aluminum pipe, the second aluminum pipe, fixing piece and steel wire clamp structure
Into；First aluminum pipe and isometric placed side by side, the both ends fixing piece fixed constraint of the second aluminum pipe, the first steel wire rope are left from the first aluminum pipe
The left end penetrated from the second aluminum pipe is held to be pierced by, the right end that the right end of the second steel wire rope from the first aluminum pipe is penetrated from the second aluminum pipe is worn
Go out；The both ends of first steel wire rope link together in the left end remittance merga pass steel wire clamp of the first aluminum pipe, the second steel wire rope
Both ends the first aluminum pipe right end converge merga pass steel wire clamp link together.It passes through the plasticity of aluminum pipe axial direction
Deformation achievees the purpose that energy dissipating, energy consumption.
But there are problems with for the patent：
1st, there are two strand steel wire ropes in every aluminum pipe, can produce friction during the motion between rope and rope, cause the mill of steel wire rope
Damage, triggers the disrumpent feelings of steel wire rope；
2nd, since the energy of two strand steel wire ropes friction consumption cannot measure, working status is unclear, can not match conjunction in use
Suitable energy dissipation piece；
3rd, aluminum pipe is in deformation process, on the one hand, the fold that aluminum pipe plastic deformation produces may block steel wire rope, the opposing party
Face, producing can intercouple in the aluminum pipe and two strand steel wire rope motion processes of plastic deformation, interact, influence each other, and easily lead
Aluminum pipe deformation is caused to be not thorough, energy dissipation piece cannot give full play to energy-absorbing function.
The content of the invention
In view of the problems of the existing technology, the technical problems to be solved by the invention are just to provide one kind by metal control
Into energy dissipator, it is avoided that the friction in metal tube between steel wire rope, metal tube deformation thoroughly, performance stablize, user
Just.
The technical problems to be solved by the invention are that technical solution in this way is realized, it includes fixing piece, metal
Pipe, steel wire rope, line card and intermediate plate, fixing piece are the metal derby for being provided with two groups of symmetrical countersunk head through holes, and two fixing pieces are relatively
The embedded metal tube in countersunk head groove, the countersunk head groove of countersunk head through hole are used for the termination for constraining metal tube；
Steel wire rope enters from the countersunk head through hole of a fixing piece, and through metal tube, steel wire rope one end is anchored at another by intermediate plate
In the through hole of a fixing piece countersunk head through hole；Steel wire rope is outwards drawn from one group of symmetrical countersunk head through hole in fixing piece, by fixing piece
One group of steel wire rope that outside is drawn merges, and is linked together by line card.
The solution have the advantages that：
When passive flexible protection systems are by rock-fall impact, after the pulling force produced in steel wire rope reaches a certain level, make in pulling force
Under, the steel wire rope being anchored in fixing piece pulls fixing piece relative motion, and then equal compression metal tube consumes energy.Due to each
A metal tube wears steel cable, avoids friction of two strand steel wire ropes in same metal tube, from overcoming steel wire rope
The deformation of disrumpent feelings and aluminum pipe by steel wire rope it is stuck the problem of；
In addition, the startup of the present invention and work load size depend on material characteristic, quantity, length and the cross section ruler of metal tube
It is very little, and above-mentioned several determinants can accurately be measured according to requirement of engineering, and then solve mechanical mechanism complexity, deformation
It is not thorough, the problem of working status is unclear, performance is unstable.
Compared with prior art, it is an advantage of the invention that：The friction between steel wire rope in metal tube is avoided, metal tube becomes
Shape is thorough, performance is stablized, easy to use.

Embodiment
The invention will be further described with reference to the accompanying drawings and examples：
Embodiment 1
As depicted in figs. 1 and 2, the present embodiment includes fixing piece 1, metal tube 2, steel wire rope 3, line card 4 and intermediate plate 5, and fixing piece 1 is
The rectangle metal derby of two groups of symmetrical countersunk head through holes 6 is provided with, two fixing pieces 1 are relatively embedded in metal tube 2 in countersunk head groove,
The countersunk head groove of countersunk head through hole 6 is used for the termination for constraining metal tube 2；
The countersunk head through hole 6 of steel wire rope 3 from a fixing piece enters, and through metal tube 2,3 one end of steel wire rope is anchored at by intermediate plate 5
In the through hole of another fixing piece countersunk head through hole 6；Steel wire rope 3 is outwards drawn from one group of symmetrical countersunk head through hole 6 in fixing piece 1,
The one group of steel wire rope 3 drawn by the outside of fixing piece 1 merges, and is linked together by line card 4.
Symmetrical one group of steel wire rope 3 is fixed together common stress, its resultant direction is located at 1 line of centres of fixing piece
On.
Embodiment 2
As shown in Figure 3 and Figure 4, the present embodiment is as different from Example 1：Fixing piece 1 is to be provided with two groups of symmetrical countersunk head through holes
Circular metal block, symmetrical countersunk head through hole is uniformly distributed circumferentially.
It is contemplated that fixing piece 1 can also be the square-shaped metal block for being provided with two groups of symmetrical countersunk head through holes, it is symmetrical heavy
Head through hole is evenly distributed on diagonal.
In above-described embodiment, symmetrical countersunk head number of through-holes only has 2, and certainly, countersunk head number of through-holes can be 3 or more
Multiple one group of symmetrical countersunk head through hole for forming symmetry.
Fixing piece 1 mainly plays fixed and position-limiting action.There is symmetrical metal tube between fixing piece, fixing piece 1 is provided with two groups
Symmetrical countersunk head through hole 6, the throughhole portions of countersunk head through hole 6 are used for the end of anchoring steel wire rope, countersunk head groove for constraining metal tube 2
