Description

A kind of elasticity crane cable

Technical field

The utility model relates to power cable technical field more particularly to a kind of elastic crane cables.

Background technique

With the development of society, city is more and more for the demand of the energy, but due to the energy characteristic distributions in China, To the phenomenon that west-to-east power transmission occur, and realize the power transmission mode of high pressure or extra-high voltage technically with during transportation Reduce loss.Cable is generally set up in the sky or for being attached between machinery, but traditional cable makes under general environment With more stable, but cable, during installation, cable core sheath is pressed on cable core, and sheath is made to generate biggish rub with cable core It wipes, then sheath axial deformation under pressure, axial to cable core generation pulls power, causes cable core to be dragged disconnected.It is existing The construction of cable, limited strength are easy the situations such as locally to be squeezed and the exposed or internal insulating layer or heat-insulated of breakage occur The damaged phenomenon of layer, to be easy to appear short circuit, the problem of heat resistance reduces, when cable is squeezed, inside is led The conducting wire of electro ultrafiltration, which is pressed together, leads to poor heat dissipation performance, abrasion and short circuit.

Utility model content

The purpose of the utility model is to provide a kind of elastic crane cables, solve normal cable in construction and installation, cable Outer wall leads to the problem that multiple conducting wires are extruded or inside is heat-insulated, insulating layer is damaged vulnerable to external force.

In order to solve the above technical problems, the utility model adopts the following technical solution:

The utility model provides a kind of elastic crane cable, from inside to outside successively includes metallic conductor, is located at the gold Belong to insulating layer, heatproof sleeve tube layer, buffer layer, elastic layer and the wearing layer on the outside of conductor；The peripheral side of the buffer layer is uniform Interval is preset with arcuate rib, the vestibule that the arcuate rib internal preset has convenient for shrinking；The section of the arcuate rib is Arcuate structure, and its outer convex globoidal is greater than 180 degree, reserves uniform intervals, the elastic layer between the adjacent arcuate rib With the adjusting rib for being preset with the prepared separation between the arcuate rib on one side and being adapted to of the buffer layer contacts, the adjusting rib It is in the strip of inverted trapezoidal for section；Under no external force, the periphery of the side for adjusting rib and the arcuate rib Wall contact, and the arcuate rib plays a supporting role to the elastic layer by the adjusting rib.

Further, multiple metallic conductors wrapped up in insulating layer are mounted in the buffer layer.

Further, metal armor layers are also equipped between the metallic conductor and the buffer layer.

Further, the buffer layer is an integral molding structure with the arcuate rib, and the buffer layer is rubber material Matter.

Further, the insulating layer is high-temperature cable casing.

Further, the vestibule is elliposoidal air bag.

Further, the wearing layer is abrasive rubber material.

Compared with prior art, the advantageous effects of the utility model: in the application, when by external force, energy External force is offset in enough mating reactions by installing buffer layer and elastic layer inside cable, prevents from being damaged inside cable, together When buffer layer and elastic layer alternating expression fit system can prevent it is opposite slip, to improve the inside and outside company of cable The stability connect.

Detailed description of the invention

The utility model is described in further detail for explanation with reference to the accompanying drawing.

Fig. 1 is the schematic diagram of the truncation surface of the utility model elasticity crane cable.

Description of symbols: 1, metallic conductor；101, insulating layer；102, heatproof sleeve tube layer；2, buffer layer；201, arcuate rib Item；202, vestibule；3, elastic layer；301, rib is adjusted；4, wearing layer.

Specific embodiment

As shown in Figure 1, a kind of elasticity crane cable, successively includes metallic conductor 1, is located at the metallic conductor from inside to outside Insulating layer 101, heatproof sleeve tube layer 102, buffer layer 2, elastic layer 3 and wearing layer 4 outside 1；The peripheral side of the buffer layer 2 Uniform intervals are preset with arcuate rib 201, the vestibule 202 that 201 internal preset of arcuate rib has convenient for shrinking；The arc The section of rib 201 is arcuate structure, and its outer convex globoidal is greater than 180 degree, after removing convenient for external force, the arcuate rib 201 Rib 301 will be adjusted and squeeze back original state, reserve uniform intervals, the elastic layer 3 and institute between the adjacent arcuate rib 201 That states the contact of buffer layer 2 is preset with the adjusting rib 301 that prepared separation is adapted between the arcuate rib 201, the tune on one side Saving rib 301 is the strip that section is in inverted trapezoidal, wherein the elastic layer 3 is high-strength polyurethane or nitrile rubber material； Under no external force, the side for adjusting rib 301 is contacted with the periphery wall of the arcuate rib 201, and described Arcuate rib 201 plays a supporting role to the elastic layer 3 by the adjusting rib 301；When by external force, the adjusting rib The gap bottom of 301 insertion arcuate ribs 201, so that absorbing external active force, plays the role of protecting cable.

In the present embodiment, multiple metallic conductors 1 wrapped up in insulating layer 101 are mounted in the buffer layer 2.The metal Metal armor layers are also equipped between conductor 1 and the buffer layer 2, for protecting cable.The buffer layer 2 and the arcuate rib Item 201 is an integral molding structure, and the buffer layer 2 is rubber material, and the vestibule 202 is elliposoidal air bag, consequently facilitating rising To flexible buffering external force.The insulating layer 101 is high-temperature cable casing, plays protection cable, and the wearing layer 4 is abrasive rubber Material, so that playing the role of that cable outer wall is avoided to be damaged during installation.

In the description of the invention, it is to be understood that term " longitudinal direction ", " transverse direction ", "upper", "lower", " preceding ", The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on Orientation or positional relationship shown in the drawings, be merely for convenience of description the present invention, rather than the device of indication or suggestion meaning or Element must have a particular orientation, be constructed and operated in a specific orientation, therefore be not considered as limiting the invention.

Embodiment described above is only that the preferred embodiment of the invention is described, not to the utility model Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are practical new to this The various changes and improvements that the technical solution of type is made should all fall into the protection scope that the utility model claims book determines It is interior.
