Description
Technical Field
The invention relates to the field of elevator balance compensation chains, in particular to a carbon fiber reinforced cold-resistant flame-retardant balance compensation chain for a manned high-speed elevator.
Background
The elevator balance compensation chain is mainly used for connecting a car and a counterweight of an elevator, balancing the weight of a traction rope and a trailing cable, and is a component playing a balance role in the operation of the elevator, generally, in the operation process of the elevator, the lengths of steel wire ropes on the car side and the counterweight side are continuously changed, so that the weight change of the steel wire ropes on two sides of a traction wheel is caused, when the car is positioned at the lowest landing, most of the weight of the steel wire ropes is acted on the car side, when the car is positioned at the highest landing, most of the weight of the steel wire ropes is acted on the counterweight side, when the lifting height of the elevator is not large, the influence on the operation performance of the elevator is small, but when the elevator is lifted to a certain height, the stability of the operation of the elevator is seriously influenced, and the safety of passengers is endangered, therefore, when the lifting height of the elevator exceeds a certain height, a component with certain weight must be arranged to balance the, this requires balancing of such weight changes by the elevator balancing compensation chain.
The following compensation chains are mainly available in the market:
first, the reeving elevator compensation chain, which is the most primitive type of compensation chain, is limited to elevators with a travel speed of less than 1.75 m/s. The balancing compensation chain can be realized by only penetrating hemp ropes into the iron chain. Due to the fact that friction and collision can occur between chains in the using process, noise is high, people have obvious shaking sense in an elevator car, and most elevator companies abandon the elevator at present. The only advantage is that it is relatively inexpensive.
The second kind, the balanced compensation chain of elevator is moulded to the package, for reducing the noise of reeving compensation chain at the operation in-process, slows down the corruption that causes the iron chain because of the environment simultaneously, has so wrapped up the one deck PVC hose on the reeving elevator compensation chain, has formed the compensation chain is moulded to the package. Compared with a rope threading compensation chain, the noise is greatly reduced when the plastic-coated compensation chain runs, and the plastic-coated compensation chain is more attractive. The only disadvantage is that improvements in flexibility and durability are still needed.
And thirdly, the full-plastic elevator balance compensation chain can be used for operating a high-speed elevator with the speed of 6 m/s. The outer surface of the elevator is of a cable-shaped PVC structure, so that the elevator can keep a stable and silent effect during operation, and is popular with many large-scale elevator companies.
Chinese patent publication No. CN1222704C discloses an elevator balance compensation chain and a manufacturing method thereof. The iron chain is arranged in the rubber column body, and the fiber layer is wrapped on the rubber column body. The manufacturing method comprises the following steps: rust removal of an iron chain; extruding the rubber material into a mold and wrapping the mold on an iron chain to form a rubber cylinder; putting the rubber column into a mould, and extruding fiber materials into the mould to wrap the outer surface of the rubber column to form a fiber layer; after vulcanization, cooling and shaping, trimming and finishing to obtain the product. When the elevator balance compensation chain operates, the noise is low, the wear resistance is good, and the tearing strength and the elongation at break are high. But because each lock ring is movably connected, certain friction is generated in the high-speed moving process of the elevator balance compensation chain, and the long-time friction easily causes the abrasion of the lock ring sleeve.
The carbon fiber is a special fiber composed of carbon elements. The carbon fiber has the characteristics of high temperature resistance, friction resistance, electric conduction, heat conduction, corrosion resistance and the like, is fibrous and soft in appearance, can be processed into various fabrics, and is a one-dimensional structure carbon material mainly formed by sp2 hybridization. The carbon fiber has certain activity on the surface, so that the carbon fiber and the polymer can form a composite material, the composite material has the characteristics of light weight, high strength and the like, and the modulus of the composite material prepared by the carbon fiber can be even comparable to that of metal. Because the graphite microcrystalline structure of the fiber is preferentially oriented along the fiber axis, the fiber has high strength and modulus along the fiber axis. The carbon fibers have a low density and thus a high specific strength and a high specific modulus. The carbon fiber is mainly used as a reinforcing material to be compounded with resin, metal, ceramic, carbon and the like to manufacture advanced composite materials. The carbon fiber reinforced epoxy resin composite material has the highest specific strength and specific modulus in the existing engineering materials, and the safety use performance of the elevator balance compensation chain can be greatly improved when the carbon fiber is applied to the manufacturing of the elevator balance compensation chain.
The existing elevator balance compensation chain lock chain is in the using process, certain friction can be generated in the high-speed moving process of the elevator balance compensation chain due to the movable connection among the lock rings, long-time friction easily causes abrasion of lock ring sleeves, especially some cold-intolerant lock ring sleeves are easy to crack when meeting extremely cold weather, direct mutual friction among the lock rings exposed outside after cracking is extremely likely to generate sparks, and small sparks can cause fire disasters and have huge potential safety hazards when in serious conditions.
