Abstract

The utility model provides a high -speed low pressure reel cable for hoist, it includes the tensile SMIS, the tensile SMIS is the outer cladding elastomer of aircraft wire rope, and the transposition has a plurality of layer line cores outside the tensile center, and is outmost the outer cladding of sinle silk has the enhancement layer, sheath in the crowded package in the space between enhancement layer and the tensile SMIS, and the outer parcel of enhancement layer has exodermis, interior outer jacket. Compared with the prior art, the utility model discloses following beneficial effect has: 1. The tensile SMIS is the outer cladding elastomer of aircraft wire rope, can bear the dead weight of cable when high -speed vertical lift and assault strength. 2. Insulation core adopt the aramid fiber to strengthen, smart thin copper wire kinks the structure flexible conductor again, has increased resistant bending, the tensile strength of conductor.

Description

A kind of high velocity, low pressure drum cable for suspender

Technical field

The utility model relates to a kind of high velocity, low pressure drum cable for suspender, belongs to crane cable technical field.

Background technology

Current suspender drum cable is used on the rotary machine of large-scale suspender of harbour machinery, environment for use is outdoor humidity and has salt fog to corrode, require that cable has excellent weathering resistance, salt fog resistance performance, cable uses with suspender oscilaltion, the speed of service is very fast, due to the startup of every subjob suspender and acceleration at stall very high, and add that cable is conducted oneself with dignity, require high to the tensile property of cable, the anti-wear performance of sheath material.

Utility model content

For defect of the prior art, the purpose of this utility model is to provide a kind of high velocity, low pressure drum cable for suspender.

The utility model is achieved through the following technical solutions:

A kind of high velocity, low pressure drum cable for suspender, it comprises tension SMIS, and stranded outside described tension SMIS have some layer line cores, and outermost described core is coated with reinforced layer, extrude sheath in space between described reinforced layer and tension SMIS, and reinforced layer is wrapped with outer jacket.

Preferably, described tension SMIS is wrapped in outside aircraft cable by elastomer layer and forms.

Preferably, described line core layer comprises conductor, polyurethane insulating layer and cotton braid, and described insulating barrier is wrapped in outside conductor, and described braid is wrapped in outside insulating barrier.

Preferably, the stranded lay ratio of the line core layer described in every layer is all less than 12.

Preferably, described conductor is formed by stranded again by meticulous copper wire.

Preferably, also stranded in described conductor have aramid fiber.

Preferably, interior outer jacket adopts cross-linking radiation polyurethane material.

Preferably, aramid fiber braiding reinforced layer is set between interior outer jacket.

Compared with prior art, the utility model has following beneficial effect:

1. tension SMIS is aircraft cable outer cladding elastomer, can bear the deadweight of cable when high velocity vertical is elevated and impact strength.

2. insulation is outer adopts cotton braid, improves the antitorque tensile property of core further, each layer line core energy close-packed arrays.

3. many cores adopt concentric stranding, and stranded lay ratio is little, and the outside diameter of cable is little, and bending radius is little.

4. aramid fiber braiding reinforced layer is set between outer jacket in, humidification is played to sheath entirety, improves the anti-tensile tensile strength of cable.
