Description
Technical field
The utility model relates to field of cables, and in particular to a kind of bridge detection cable.
Background technique
Cable is usually the cable of similar rope as several or made of several groups of wire strandings, between every group of conducting wire mutually absolutely
Edge, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation, and cable has interior energization, external insulation
Feature.
Bridge detection cable, to prevent protective coverings of cable impaired, improves service life, cable applies because using in particular surroundings
If when need to penetrate in a protection sleeve pipe, both increase difficulty of construction and cost in this way, and cable band can be also given during poling
Centainly damage.
Therefore it is badly in need of providing a kind of structural strength height, wearability is good, bridge detection cable with long service life.
Utility model content
The purpose of this utility model is the deficiency for existing highway bridge detection cable, provides a kind of structural strength height, wear-resisting
Good, the bridge detection cable with long service life of property.
The utility model provides following technical solution:
A kind of bridge detection cable, including cable core, be successively coated with outside the cable core insulating layer, shielded layer, first plus
Strong layer, armor, oversheath, filled layer and the second enhancement layer, first enhancement layer are along the circumferential direction arranged by several round steel
It arranges, second enhancement layer is nitrile rubber, and second enhancement layer is equipped with wearing piece, and the wearing piece includes successively phase
Wear-resisting head, connecting rod and mounting head even, the mounting head are located in the filled layer, and the connecting rod passes through described second and reinforces
Layer, the wear-resisting head are located at outside second enhancement layer.
Preferably, the filled layer is PVC, and doping is equipped with diamond dust and ceramic particle in the filled layer, be can be improved
The wear-resisting property of filled layer.
Preferably, the oversheath is low smoke halogen-free flame-retardant polyolefin oversheath, and the outside of the oversheath is equipped with uniform
The bandage of distribution can enhance the structural strength of each layer within oversheath, prevent from that the loose problem of generation is used for a long time, therefore use the longevity
Life length.
Preferably, the armor is copper strip layer, and structural strength is high.
Preferably, the shielded layer is copper wire mesh braided layer, and shield effectiveness is good.
Preferably, the insulating layer is crosslinked polyethylene, and insulation effect is good.
The beneficial effects of the utility model are:
(1) the utility model is equipped with wearing piece, and wear-resisting head can be improved the wear-resisting property of the second enhancement layer, pass through connecting rod phase
Mounting head even is located in filled layer, can enhance the fastness of wearing piece, prevent wearing piece from falling off.
(2) the utility model, which is equipped with, is along the circumferential direction arranged by several round steel into the first enhancement layer, can enhance electricity
The structural strength of cable, prolongs its service life.

Specific embodiment
As shown in Figure 1 to Figure 3, a kind of bridge detection cable, including cable core 1, be successively coated with outside cable core 1 insulating layer 2,
Shielded layer 3, the first enhancement layer 4, armor 5, oversheath 6, filled layer 7 and the second enhancement layer 8.
Second enhancement layer 8 is nitrile rubber, and the second enhancement layer 8 is equipped with wearing piece 12, and wearing piece 12 includes being sequentially connected
Wear-resisting head 121, connecting rod 122 and mounting head 123, mounting head 123 are located in filled layer 7, and connecting rod 122 passes through the second enhancement layer 8, resistance to
Bistrique 121 is located at outside the second enhancement layer 8.Wear-resisting head 121 can be improved the wear-resisting property of the second enhancement layer 8, pass through connecting rod 122
Connected mounting head 123 is located in filled layer 7, can enhance the fastness of wearing piece 12, prevents wearing piece 12 from falling off.
Filled layer 7 is PVC, and doping is equipped with diamond dust 9 and ceramic particle 10 in filled layer 7, can be improved the resistance to of filled layer 7
Grind performance.
Oversheath 6 is low smoke halogen-free flame-retardant polyolefin oversheath, and the outside of oversheath 6 is equipped with equally distributed bandage 11,
The structural strength that each layer within oversheath 6 can be enhanced prevents that the loose problem of generation, therefore long service life is used for a long time.
Armor 5 is copper strip layer, and structural strength is high.
First enhancement layer 4 is along the circumferential direction arranged by several round steel, can enhance the structural strength of cable, is extended
Its service life.
Shielded layer 3 is copper wire mesh braided layer, and shield effectiveness is good.
Insulating layer 2 is crosslinked polyethylene, and insulation effect is good.
The advantage of the utility model are as follows: structural strength is high, and wearability is good, long service life.
The foregoing is merely the preferred application cases of the utility model, are not intended to limit the utility model, although reference
The utility model is described in detail in previous embodiment, for those skilled in the art, still can be right
