There is internal screw 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, support rod I, support 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.
Utility model content
The purpose of this utility model is to provide a kind of bridge cable anti-collision structures, it is intended to solve drag-line in the prior art
Occur to destroy due to accidental shock, 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 utility model is achieved through the following technical solutions:
The utility model provides a kind of bridge cable anti-collision structure, comprising: filled layer and external protection coating, the filling
Layer is set on drag-line outer surface, and 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, absorbs energy for clamping drag-line and 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 on the otic placode, and the external protection coating passes through on 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 any 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.
The advantages of the utility model:
1. the drag-line anti-collision structure of the utility model is other than external protection coating, between drag-line cable body and external protection coating
It is also provided with the filled layer for buffering, further increases the impact resistance of cable body.
2. the external protection coating and filled layer in the drag-line anti-collision structure of the utility model are assembled by two parts,
Product installation and maintenance aspect have higher convenience.
