Abstract
The utility model relates to externally-hung trailing cable which matches an elevator, and aims to solve technical problems that an elevator cable provided by the utility model is simple and convenient in manufacturing and mounting, and low in cost. The technical scheme of the utility model is that a novel elevator cable provided with a video symmetrical cable comprises a cable sheath with a flat cross section, a plurality of sets of power lines arranged in the cable sheath in a parallel manner, and two tensile members, wherein the two tensile members are respectively disposed on the two ends of the cable along the width direction of the cable. The novel cable is characterized in that the center of the cable sheath is provided with two parallel-arranged video wires; each video wire comprises two video twisted insulation cores and two core tensile members, and the two video twisted insulation cores and the two core tensile members are wrapped by a shielding layer; each video twisted insulation core is composed of a conductor and a plastic insulating layer wrapped on the outer circumference of the conductor; the shielding layer is a brass wire mesh grid; each core tensile member is a twisted plastic robe; and each tensile member is a galvanizing steel wire cluster.
Description
Technical field
The utility model relates to a kind of cable, especially the matching used external hanging type trailing cable of elevator.
Background technology
Cable is the basic accessory of lift facility; The conventional structure of elevator trailing cable comprises the cable cover(ing) of flattened cross-sectional and is arranged in parallel within some groups of power lines in the cable cover(ing).In addition, elevator also must be equipped with the video symmetrical cable of transmit video signal.The trailing cable of existing all kinds of elevators and video signal transmission cable independent installation respectively lay, and this has not only improved manufacturing and installation cost, also are unfavorable for maintenance.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that the above-mentioned background technology exists, and a kind of improvement of elevator cable is provided, and this elevator cable should have makes and install simple and convenient, lower-cost characteristics.
The technical scheme that the utility model provides is: the novel elevator cable of inserting the video symmetrical cable; Comprise the cable cover(ing) of flattened cross-sectional and be arranged in parallel within some groups of power lines and two tensile members in the cable cover(ing), two tensile members are positioned at the two ends of cable widths direction; The middle part that it is characterized in that described cable cover(ing) two video lines that also laterally arrange; Every video line includes two stranded insulated wire cores of video and two cores of being coated by screen and bears part, and the stranded insulated wire cores of said video is made up of conductor and the plastic insulating layer that is coated on the conductor excircle.
Said screen is the copper wire mesh grid.
It is stranded plastic ties that said core bears part.
Said tensile member is the galvanized steel tow.
The beneficial effect of the utility model is: because the video pair cable is inserted in the elevator cable (trailing cable); Changed these two kinds of cables mode of external hanging type installation (video signal transmission cable and elevator cable independent installation respectively lay) respectively; Reduce system's manufacturing and installation cost, also maintained easily maintenance.Simultaneously, the pair cable of inserting evenly twists together with a constant pitch, has utilized the principle of conductors cross transposition; Reduced the signal interference, effectively suppressed common mode disturbances, added the copper wire mesh grid as screen; Even under strong interference environment, it is stable that the signal transmission still keeps.
Description of drawings
Fig. 1 is the cross-sectional structure sketch map of the utility model.
Embodiment
As shown in the figure; Insert the novel elevator cable of video symmetrical cable; The cable cover(ing) 2 that comprises flattened cross-sectional (is that drawing is clear; Hatching is omitted in the cable cover(ing) cross section) and be arranged in parallel within some groups of power lines 3 in the cable cover(ing) (can know among the figure: totally six groups of power lines, every group of power line comprises the lead of six roots of sensation band crust; The quantity of power line is confirmed as requested) and two tensile members 1 (tensile member recommends to adopt the galvanized steel tow), two tensile members 1 are positioned at the two ends of cable widths direction.This is the conventional structure of elevator cable.
The improvement of the utility model is two video lines 5 that also laterally arrange in the middle part of described cable cover(ing), and every video line includes two stranded insulated wire cores 5-2 of video and two cores bear part 5-3.The stranded insulated wire cores of said video is formed (the stranded insulated wire cores of video is a conventional structure) by conductor and the plastic insulating layer that is coated on the conductor excircle.Can be known by figure: equal symmetry of said video line, power line and tensile member and in-line are arranged in the cable cover(ing).
Said screen recommends to adopt the copper wire mesh grid.
Said core bears part and recommends to adopt special-purpose stranded plastic ties.
Said tensile member recommends to adopt the galvanized steel tow.
When the utility model is made; Only need tensile member 1, power line 3, the video line 5 that coated by screen 5-1 are arranged in parallel; Pass through the platypelloid type mould of the extruder head of injection molding machine then, can make the novel elevator cable of inserting the video symmetrical cable, only need the cooling of process tank to get final product subsequently.
Claims (4)
