It is whole tubular structure that pillar, which is single-layer type structure, protection effect unobvious, and protecting tube, convenience when installation maintenance
Difference.
Such as a kind of Chinese utility model patent " steel strand stay cable housing of collision-damage-prevention of Publication No. CN205934724U
Pipe ", outer tube are arranged above cable guide pipe, for protecting suspension cable, outer tube anti-including sequentially connected steel from lower to upper
Water cover, steel pipe, HDPE connector sleeves and HDPE pipes, the vertical height of the top of the steel pipe apart from bridge floor are not less than 2.5m.Steel
Pipe forms external screw thread close to the tube body periphery on top, and correspondingly, the HDPE connector sleeves are molded on the internal perisporium of bottom end
There is internal thread.
Such as a kind of Chinese utility model patent " oblique pulling cable body anticollision device, collision-prevention device " of Publication No. CN206204785U, by pipe
Body and buffer composition, the buffer are connected on inboard wall of tube body, and buffer is by pedestal, connecting shaft, supporting rod I, supporting rod
II, idler wheel, spring and spring column composition.
By the above content it can be found that the core of cable body anticollision device, collision-prevention device is setting set outside cable body in the prior art
Pipe, but its single layer structure damping capaicty is poor, and installation maintenance is more inconvenient.
Invention content
The purpose of the present invention is to provide a kind of bridge cable anti-collision structures, it is intended to solve in the prior art drag-line due to
Accidental shock and occur destroy, the problem of harmful energy that external impact process generates drag-line can not be slowed down.
To realize above-mentioned technical purpose and the technique effect, the invention is realized by the following technical scheme：
The present invention provides a kind of bridge cable anti-collision structures, including：Filled layer and external protection coating, the filled layer are worn
It is sleeved on drag-line outer surface, the external protection coating is fixed on the outer surface of the filled layer.
The filled layer is integrally divided into two semi cylindrical portions, for drag-line to be clamped and absorbs energy by passive deformation
Impact mitigates damage of the energy impact to drag-line.
The external protection coating is integrally divided into two semi cylindrical portions, for fixing filled layer and resisting rushing for external hard object
It hits.
Otic placode is provided on the external protection coating, with has bolt hole, the external protection coating to pass through on otic placode on the otic placode
Bolt hole be bolted, maintenance easy to disassemble.
The external protection coating uses high-strength material, and the destruction of generation is directly hit for resisting external hard object.
The high-strength material is arbitrary in strong concrete, fibre reinforced composites or high-strength metal material
It is a kind of.
The filled layer is using flexible energy-absorbing material, for absorbing the harmful energy generated in shock or impact process.
The flexibility energy-absorbing material is any one in foamed aluminium, polyurethane foam, polyureas or rubber.
Advantages of the present invention：
1. the drag-line anti-collision structure of the present invention is also set other than external protection coating between drag-line cable body and external protection coating
The filled layer for buffering has been set, the impact resistance of cable body is further increased.
2. the external protection coating and filled layer in the drag-line anti-collision structure of the present invention are assembled by two parts, in product
There is higher convenience in terms of installation and maintenance.

Fig. 2 is the decomposition diagram according to the bridge cable anti-collision structure of one embodiment of the invention；
Fig. 3 is the schematic cross section according to the bridge cable anti-collision structure of one embodiment of the invention；
In figure, 100 be filled layer, and 200 be external protection coating, and 300 be drag-line, and 201 be otic placode, and 202 be bolt hole.
Specific implementation mode
In order to make the purpose of the present invention, technical solution and advantage be more clearly understood, pass through below in conjunction with attached drawing specific real
Applying example, the present invention is described in more detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, and
It is not used in the restriction present invention.
A kind of bridge cable anti-collision structure is provided in an embodiment of the present invention, which sets
It is equipped with filled layer and external protection coating, filled layer can be that drag-line absorbs the harmful impact energy of major part, and external protection coating can be with
The impact damage for directly mitigating hard object, by the way that external protection coating and filled layer is arranged so that drag-line has double shock proof
Ability.Fig. 1 is according to the bridge cable anti-collision structure of one embodiment of the invention for providing drag-line double shock proof energy
Power, as shown in Figure 1, the bridge cable anti-collision structure includes filled layer 100 and external protection coating 200, wherein filled layer 100 is worn
On 300 outer surface of drag-line, the harmful energy impact conducted to drag-line 300 via external protection coating 200 can be absorbed, to drag-line
300 direct protective actions；External protection coating 200 is fixed on the outer surface of the filled layer 100, can directly absorb hard object punching
The destruction for hitting generation passes through the cooperation of external protection coating 200 and filled layer 100 so that drag-line 300 has double shock proof
Ability has preferable protective effect to drag-line 300.
As shown in Figure 2 and Figure 3, the filled layer 100 is whole is divided into two semi cylindrical portions, for drag-line 300 to be clamped and leads to
It crosses passive deformation and absorbs outside energy impact；External protection coating 200 is whole to be also classified into two semi cylindrical portions, for fixing filled layer
100 and resist the impact of external hard object；It can also play the role of being easily installed and safeguarding (in the prior art for protecting against shock simultaneously
Pipe sleeve be integral tubular structure, installation and safeguard it is extremely inconvenient).The external protection coating 200 also on be provided with otic placode 201, ear
With has bolt hole 202 on plate 201, and external protection coating 200 is bolted by the bolt hole 202 on otic placode 201, easy to disassemble
It safeguards.
The external protection coating 200 uses high-strength material, and wherein high-strength material can be strong concrete, fiber reinforcement
Any one in composite material or high-strength metal material directly hits the destruction of generation for resisting external hard object.
The filled layer 100 is using flexible energy-absorbing material, wherein flexible energy-absorbing material can be foamed aluminium, polyurethane foam, polyureas or rubber
Any one in glue, for absorb the harmful energy generated in shock or impact process (prior art can not absorb shock or
The harmful energy generated in impact process), the bridge cable anti-collision structure provided in an embodiment of the present invention is outer in rigidity
Under the collocation of protective layer 200 and flexible filled layer 100, it is insufficient to can be good at solving single layer pipe sleeve damping capaicty in the prior art
Drag-line deformation and dismounting is caused to safeguard more difficult problem.
