Problems solved by technology

With more and more high-rise buildings, elevators are running faster and faster. Traditional elevator cables can no longer meet the operating requirements of elevators. Problems such as core breakage and outer sheath cracking are prone to occur. Out of service failure, the whole root needs to be replaced, it is quite troublesome to repair

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] like figure 1 As shown, a reinforced bending-resistant flat control cable according to the present invention includes a flat outer sheath 1, and three diamond-shaped holes 2 and two round holes 3 are arranged in the outer sheath; The number of control wire cores is the same, and the control wire cores are composed of copper conductors 4 and flame-retardant tapes 5 extruded outside the copper conductors.

[0015] Tensile elements 6 are arranged in each round hole, and the central cores of multiple control wire cores are provided with reinforcing elements, and the reinforcing elements are composed of a steel core 7 arranged in the center and aramid yarn 8 extruded outside the steel core. Composition: Several semicircular grooves 9 are provided on the outer edge of the outer sheath 1, and the semicircular grooves are arranged at ...

Abstract

The invention discloses a reinforced type bending-resistant flat control cable. The reinforced type bending-resistant flat control cable comprises a flat outer sheath, wherein three rhombic holes and two circular holes are formed in the outer sheath; control wire cores with the same number are arranged in each rhombic hole; a tensile element is arranged in each circular hole; a reinforcing element is arranged in each middle core of the multiple control wire cores separately; a plurality of semicircular grooves are formed in the outer edge of the outer sheath; and the semicircular grooves are formed in the middle positions between every two groups of adjacent cable cores. The reinforced type bending-resistant flat control cable is simple in structure, quite high in mechanical strength and bending resistance, capable of effectively solving the problem that the core of an elevator cable is broken easily in a frequent bending environment, and also capable of prolonging the service life of the elevator cable.

Description

technical field [0001] The invention relates to the field of elevator cables, in particular to a reinforced bending-resistant flat control cable. Background technique [0002] The elevator cable is an important supporting part of the elevator. It needs to move up and down with the elevator. During this process, the elevator cable must not only bear its own weight, but also bear the stress caused by frequent U-shaped bending. With more and more high-rise buildings, elevators are running faster and faster. Traditional elevator cables can no longer meet the operating requirements of elevators. Problems such as core breakage and outer sheath cracking are prone to occur. Outage failure requires the entire root to be replaced, which is quite troublesome to repair. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reinforced bending-resistant flat control cable with simple structure, good performance and long service l...
