Description

A kind of polyurethane UD cordage and the elevator trailing comprising polyurethane UD cordage Cable

Technical field

The utility model relates to elevator trailing cable technical field, in particular to a kind of polyurethane UD cordage and include this The elevator trailing cable of polyurethane UD cordage.

Background technique

Story height is more than 60 meters at present and elevator speed is more than in the elevator trailing cable of 2.5 meter per seconds generally using anti- Steel wire is drawn to improve the tensile strength of trailing cable as the reinforcing element of trailing cable, main arrangement can participate in figure 1 and Fig. 2, tensile steel wire 1 are arranged in the surrounding layer 3 of trailing cable 2.Since 1 surface of tensile steel wire is smooth, with trailing cable Frictional force between 2 surrounding layer 3 is smaller, contributes not enough the tensile strength of trailing cable, tensile steel wire 1 is being added Afterwards, the pliability of trailing cable is also inferior many.In addition need to increase the suspension fixation device of tensile steel wire 1 and cumbersome during installation Steel wire rope connector production.In Super High building, the weight of trailing cable can also increase because of tensile steel wire 1, give elevator Energy consumption reduce and operation balance increase technical difficulty.

Utility model content

The two of technical problem to be solved in the utility model are to provide a kind of substitution tensile steel wire as trailing cable In reinforcing element polyurethane UD cordage.

It is to provide after the utility model above-mentioned technical problem of being solved a kind of comprising above-mentioned polyurethane UD cordage Elevator trailing cable.

The polyurethane UD cordage of first aspect as the utility model, including twist twist UD yarn and extrusion molding be coated on it is described The polyurethane clad twisted on UD yarn circumference is twisted, the axis of the two is parallel.

As the elevator trailing cable comprising above-mentioned polyurethane UD cordage of the utility model second aspect, the elevator Trailing cable includes external sheath layer, which is characterized in that the polyurethane UD cordage is arranged in the external sheath layer axial direction Two sides and parallel with the elevator trailing cable.

As the elevator trailing cable comprising above-mentioned polyurethane UD cordage of the utility model second aspect, the retinue Cable includes external sheath layer and is arranged in several cables in the external sheath layer and parallel with the axis of the external sheath layer, It is characterized in that, the polyurethane UD cordage setting is in each cable and parallel with the cable.

Polyurethane UD cordage polyurethane clad and twirl due to using technical solution as above, in the utility model Twist the friction between the frictional force between UD yarn and the insulating layer of the core wire between the surrounding layer of trailing cable or in cable Power is all bigger, thus improve the tensile strength of trailing cable and improve simultaneously the pliability of trailing cable and alleviate with The weight of row cable.Simultaneously without the fixation device of installation suspension tensile steel wire, installation cost is saved.

Specific embodiment

The utility model is described in detail below in conjunction with the drawings and specific embodiments.

Referring to Fig. 1, polyurethane UD cordage 10 shown in figure, including twirl twists UD yarn 11 and extrusion molding is coated on twirl and twists UD yarn In addition polyurethane clad 12 on 11 circumference can also constitute clad by wear-resisting PVC or wear-resisting low-smoke halogen-free polyolefin, The axis of the two is parallel.It twists strand UD yarn 11 to be twisted by a kind of discrete reinforcing fiber rove twirl, such as made of carbon fiber Rove or rove or the rove made of polypropylene fiber made of polyethylene fibre.

Referring to fig. 2, the elevator trailing cable shown in figure comprising above-mentioned polyurethane UD cordage 10, elevator trailing electricity Cable includes external sheath layer 20, certainly also includes the various cables being set as needed.The setting of polyurethane UD cordage 10 is protected outside The two sides of 20 axial direction of jacket layer are simultaneously parallel with elevator trailing cable.

Referring to Fig. 3, the elevator trailing cable shown in figure comprising above-mentioned polyurethane UD cordage, elevator trailing cable packet It includes external sheath layer 20 and is arranged in several cables 30 in external sheath layer 20 and parallel with the axis of external sheath layer 20, in each electricity Being twisted in cable 30 has polyurethane UD cordage 10, and polyurethane UD cordage 10 is parallel with the cable 30.

Polyurethane UD cordage polyurethane clad in the utility model and twisting twist frictional force between UD yarn and with Frictional force between the insulating layer of core wire between the surrounding layer of row cable or in cable is all bigger, to improve retinue The tensile strength of cable simultaneously improves the pliability of trailing cable and alleviates the weight of trailing cable simultaneously.Simultaneously without peace The fixation device of dress suspension tensile steel wire, saves installation cost.

Claims (3)

1. polyurethane UD cordage is coated on the polyurethane clad twisted on strand UD yarn circumference including twisting strand UD yarn and extrusion molding Clad is either made of wear-resisting PVC or wear-resisting low-smoke halogen-free polyolefin constitutes clad, and the axis of the two is parallel.

2. a kind of elevator trailing cable comprising polyurethane UD cordage described in claim 1, the elevator trailing cable packet Include external sheath layer, which is characterized in that the polyurethane UD cordage be arranged in the two sides of the external sheath layer axial direction and with The elevator trailing cable is parallel.
