Abstract
The invention discloses a composite elevator traveling electric cable comprising a non-metal extrusion body and electric cables thereof arranged inside the non-metal extrusion body. At least one optical cable running in the same direction as the electric cables is arranged in the non-metal extrusion body. Two bundles of tensile steel wires are further arranged in the non-metal extrusion body. The optical cable is composed of optical fibers, tight jackets, a reinforcing element and an optical cable sheath, wherein the optical fibers are wrapped in the tight jackets, the tight jackets are wrapped in the reinforcing element, and the reinforcing element is wrapped in the optical cable sheath. The composite elevator traveling electric cable of the invention is made by arranging the multiple electric cables, the optical cable and the tensile steel wires in a non-metal extrusion body of an existing elevator traveling electric cable, the number of electric cables in an elevator hoistway is greatly reduced, operation and maintenance of elevators are facilitated, the tensile strength of the elevator traveling electric cable is enhanced, the service life of the elevator traveling electric cable is prolonged, safe operation of the elevator electric cable is ensured, and the running efficiency of elevators is improved.
Description
Technical field
The present invention relates to a kind of cable, specifically relate to a kind of composite type elevator trailing cable.
Background technology
As everyone knows, elevator is the requisite equipment of riding instead of walk in skyscraper, want frequent moving up and down, for elevator provides the cable of working power also inevitably along with it moves up and down, and along with the needs of scientific and technological development and people's Working Life, in elevator, also needing has some activities such as communication and monitoring, for this reason, must hang relevant holding wire on elevator side, lifting repeatedly together with elevator, in elevator high-speed motion, the windage of cable is large, make the frequent tension of cable, affect useful life, and because various circuits are too complicated, and these circuits because of its tensile property relatively poor, after longer elevating movement regularly, likely there is fracture, damage, the consequence of bringing power-off stagnation of movement or other correlation functions to interrupt.In addition, common elevator communication adopts Technology of Parallel Communication, everybody must send the data of parallel communications simultaneously and accept, this just requires each communication unit must have two holding wires, if elevator floor is very high like this, the cable of parallel communications can be a lot, give making troubles up and down of elevator, and affect the speed of service of elevator, if need to install voice device additional in elevator, as audio amplifier, the settings such as emergency telephone, these must arrange corresponding cable and communicate by letter with extraneous, these cable costs are set separately high, poor safety performance, in running process of elevator, the easy fracture damage of cable, equipment in elevator cannot be used.
Summary of the invention
The object of the invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of composite type elevator trailing cable is provided, this cable is arranged on equipment cable in various telecommunication cables and elevator in elevator trailing cable, has greatly reduced the quantity of elevator hoistways inner cable, has facilitated operation and the maintenance of elevator.
To achieve these goals, the technical solution used in the present invention is: a kind of composite type elevator trailing cable, comprise the cable of nonmetal pressing body and the portion that sets within it thereof, in described nonmetal pressing body, be at least provided with one with the optical cable of the identical trend of cable, in nonmetal pressing body, be also provided with two bundle tension steel wires; Described optical cable is made up of optical fiber, tight sheath, reinforcing element and fiber cable jacket, and optical fibre packages is wrapped in tight sheath, and tight sheath is wrapped in reinforcing element, and reinforcing element is wrapped in fiber cable jacket.
Preferably, described tension steel wire is stranded steel tendon, and optical cable is positioned at the centre of two bundle tension steel wires
Adopt the invention of the technical program, its beneficial effect is: elevator trailing cable of the present invention is arranged on multi-cable, optical cable and tension steel wire in the nonmetal pressing body of existing elevator trailing cable, this has not only greatly reduced the quantity of elevator hoistways inner cable, operation and the maintenance of elevator are facilitated, and strengthen the tensile strength of elevator trailing cable, extend the useful life of elevator trailing cable, ensured the security of operation of elevator cable, improved the efficiency of elevator operation.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In figure: 1, nonmetal pressing body; 2, optical cable; 3, tension steel wire; 4, cable; 21, optical fiber; 22, tight sheath; 23, reinforcing element; 24, fiber cable jacket.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1, composite type elevator trailing cable of the present invention, comprise the cable 4 of nonmetal pressing body 1 and the portion that sets within it thereof, in described nonmetal pressing body 1, be at least provided with one with the optical cable 2 of cable 4 identical trends, in nonmetal pressing body 1, be also provided with two bundle tension steel wires 3; Described optical cable 2 is made up of optical fiber 21, tight sheath 22, reinforcing element 23 and fiber cable jacket 24, and optical fiber 21 is wrapped in tight sheath 22, and tight sheath 22 is wrapped in reinforcing element 23, and reinforcing element 23 is wrapped in fiber cable jacket 24.Described tension steel wire 3 is stranded steel tendon, and optical cable 2 is positioned at the centre of two bundle tension steel wires 3.
In use, this composite type elevator trailing cable can be adjusted as required flexibly, two bundle tension steel wires 3 can be arranged on to the both sides in nonmetal pressing body 1, allows the cable 4 of nonmetal pressing body 1 inside all between two bundle tension steel wires 3; Also can be by the partial cables 4 in nonmetal pressing body 1, part is replaced with telecommunication cable and Internet traffic cable etc., does not specifically just repeat at this.
Above are only a kind of embodiment of the present invention; not in order to limit the present invention; those skilled in the art can make various changes and improve said structure; all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
1. a composite type elevator trailing cable, comprise the cable of nonmetal pressing body and the portion that sets within it thereof, it is characterized in that: in described nonmetal pressing body, be at least provided with one with the optical cable of the identical trend of cable, in nonmetal pressing body, be also provided with two bundle tension steel wires; Described optical cable is made up of optical fiber, tight sheath, reinforcing element and fiber cable jacket, and optical fibre packages is wrapped in tight sheath, and tight sheath is wrapped in reinforcing element, and reinforcing element is wrapped in fiber cable jacket.
