Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] Such as figure 1 As shown, the cross-sectional view of the accompanying cable for high-speed parallel elevators is shown in the figure. It can be seen from the figure that the accompanying cable for high-speed parallel elevators includes a cable core and an outer sheath 100 extruded on the periphery of the cable core. The cross-section of the outer sheath 100 is roughly elliptical, so that the thickness of the accompanying cable is increased to exceed the gap between the guide rail wheels, and the accompanying cable of the present invention will not be crushed by the guide rail wheels.

[0019] The outer cylindrical surfaces 110 and 120 at the two ends of the long axis of the elliptical section are each composed of two intersecting small-di...

Abstract

The invention discloses a travelling cable for high-speed parallelly-connected elevators. The travelling cable comprises a cable core and an outer protective layer wrapped on the periphery of the cable core in squeezing mode, wherein the cross section of the outer protective layer is roughly oval, a first peripheral cylinder and a third pheripheral cylinder at two ends of a long axis direction of the oval cross section are respectively formed by two sections of converged minor-diameter arc cylinders, the converged portion of the two sections of converged arc cylinders form a concave, a second peripheral cylinder and a fourth peripheral cylinder at two ends in a short axis direction of the oval cross section are major diameter arc cylinders, and two ends of the major diameter arc cylinders are respectively in transition connection with a minor diameter arc cylinders. The travelling cable for high-speed parallelly-connected elevators has the advantages of being simple in structure, ingenious in design, capable of being effectively prevented from generating cross moving caused by wind power of a well.

Description

technical field [0001] The invention relates to the field of cables, in particular to an accompanying cable for high-speed parallel elevators. Background technique [0002] With the emergence of a large number of high-rise buildings, elevators are widely used, and the cables used in elevators have special requirements: they need to move synchronously with the elevators (accompanying cables), and they need to be used to transmit control signals. The components (such as the motor for opening and closing the elevator door, the ventilation fan on the top of the elevator, and the lights in the elevator) provide power lines for electric energy, and sometimes video lines are needed so that the personnel in the main control room can observe the situation in the elevator. [0003] Existing elevator accompanying cables are generally flat and thin. When used as a high-speed parallel elevator accompanying cable, since multiple elevators run in the same shaft, each elevator runs like a p...
