Problems solved by technology

[0009] During the use of the existing elevator balance compensation chain chain, because of the flexible connection between the lock rings, certain friction will be generated during the high-speed movement of the elevator balance compensation chain. Long-term friction will easily lead to wear of the lock ring sleeve, especially It is some lock ring sleeves that are not resistant to cold. They are easy to crack in extremely cold weather. After the cracks, the exposed lock rings will rub against each other directly and sparks are likely to be generated. In severe cases, small sparks will cause fires, which poses a huge safety hazard. Hidden danger

Abstract

The invention discloses a manned high-speed elevator carbon fiber reinforced cold-resistant and flame-retardant balance compensation chain, and belongs to the field of elevator balance compensation chains. The manned high-speed elevator carbon fiber reinforced cold-resistant and flame-retardant balance compensation chain comprises multiple lock rings and lock ring sleeves; the lock ring sleeves are wrapped on the outer sides of the lock rings; micro alarm pieces are connected between two lock rings; the lock ring sleeves are provided with insulation layers, flame-retardant layers and outer protecting layers in sequence from inside to outside; carbon fibers are applied to production of the lock ring and the lock ring sleeves of the elevator balance compensation chain; through the characteristics of high-temperature resistance, friction resistance, corrosion resistance, cold resistance, weight and high strength of carbon fiber composite materials, the safety use performances of the elevator balance compensation chain can be improved; and even if the lock ring sleeves are accidentally damaged and split, two lock rings serve as leads for contact and communication to connect with the micro alarm pieces, so that an alarm can be timely given to remind passengers and related workers, safety maintenance measures are conveniently adopted timely, and potential safety hazards are removed.

Description

technical field [0001] The invention relates to the field of elevator balance compensation chains, and more specifically, relates to a carbon fiber reinforced cold-resistant and flame-resistant balance compensation chain of a manned high-speed elevator. Background technique [0002] The elevator balance compensation chain is mainly used to connect the elevator car and the counterweight, balance the weight of the traction rope and the accompanying cable, and is a component that plays a balancing role in the operation of the elevator. The length of the wire rope on the counterweight side is constantly changing, which causes the weight of the wire rope on both sides of the traction sheave to change. When the car is at the lowest floor, most of the weight of the wire rope acts on the side of the car. When the car is at the highest floor At this time, most of the weight of the steel wire rope acts on the counterweight side. This change has little effect on the operating performan...
