Description
Technical field
The present invention relates to elevator balanced compensated chain fields, more specifically to a kind of manned high speed elevator Carbon fiber
Dimension enhances the fire retardant balanced compensated chain that resists cold.
Background technique
Elevator balanced compensated chain is mainly used for connecting the carriage and counterweight of elevator, balances the weight of hoist ropes and trailing cable
Amount, is the component that balanced action has been run to elevator, in general, elevator is in the process of running, the steel wire of cage side and counterweight-side
The length of rope is constantly changing, so as to cause the variation of traction sheave two sides wire rope weight, when carriage is located at minimum stop, steel
The weight of cord largely acts on cage side, and when carriage is located at highest stop, the weight of wirerope is largely acted on pair
Heavy side, this variation influences less the runnability of elevator when lifting height of lift is little, but is promoted and arrive certain altitude
When, the stability of elevator operation can be seriously affected, the safety of passenger can be jeopardized, for this purpose, the hoisting depth when elevator is more than one
When determining height, it is necessary to which being arranged, there is the component of constant weight to balance because of height change bring weight change, this is just needed
This weight change is balanced by elevator balanced compensated chain.
At present compensation chain on the market mainly include the following types:
The first, wire rope handling elevator compensation chain, this is a kind of compensation chain of most original, and only limiting the use of in the speed of service is 1.75
Meter per second elevator below.As long as this balanced compensated chain penetrates the rope made of hemp in iron chains.Due to chain and chain in use
Between can occur to rub and collide, noise is bigger, and people has apparent shake sense in lift car, current most of electricity
Terraced company has abandoned.Unique advantage is exactly that price is relatively cheap.
Second, plastic elevator balanced compensated chain subtracts simultaneously in order to reduce the noise of wire rope handling compensation chain in the process of running
It is slow because environment is corroding caused by iron chains, one layer of PVC hose has then been wrapped up on wire rope handling elevator compensation chain, has formd plastic benefit
Repay chain.Chain is compensated compared to wire rope handling, noise greatly reduces when plastic compensation chain is run, and more beautiful.It is unique the disadvantage is that
It still needs to improve in terms of flexibility and durability.
The third, overall plastic elevator balanced compensated chain can be used for the express elevator that the speed of service is 6 meter per seconds.Its appearance is cable
Shape PVC structure, elevator operation is able to maintain steady mute effect when use, deep to be welcome by many larger ele-vators companies.
China Patent Publication No. is that CN1222704C discloses a kind of Elevator balance compensation chain and Manufacture Method.It includes
Iron chains, rubber cylinder, fibrous layer, above-mentioned iron chains are placed in above-mentioned rubber cylinder, and above-mentioned rubber cylinder is wrapped with fibrous layer.The manufacture
Method are as follows: iron chains derusting；Sizing material is expressed to be wrapped on iron chains in mold, rubber cylinder is made；Rubber cylinder is placed in mould
Tool, then fiber material is expressed in mold and is wrapped in rubber cylinder outer surface composition fibrous layer；After vulcanization, cooling and shaping, deburring
It arranges and is made.When the elevator balanced compensated chain is run, low noise, wearability are good, and tearing strength and elongation at break are high.But
Because being flexibly connected between each lock ring, certain friction can be generated in elevator balanced compensated chain high speed movement, when long
Between friction be easy to cause lock ring cover abrasion.
Carbon fibe is a kind of special fibre of carbon composition.With high temperature resistant, anti-friction, conductive, thermally conductive and corrosion-resistant
Etc. characteristics, shape can be processed into various fabrics in threadiness, soft, Carbon fibe be it is a kind of mainly formed with sp2 hydridization it is one-dimensional
Structure Carbon Materials.The Carbon fibe activity certain since surface has can constitute this composite material of composite material together with polymer
Have the characteristics that weight, intensity are high, can even be compared favourably now with metal by its modulus of composite material of Carbon fibe preparation.By
In its graphite microcrystalline structure along fiber axle preferrel orientation, therefore there is very high intensity and modulus along fiber axis direction.Carbon fibe
Density is small, therefore specific strength and specific modulus are high.Carbon fibe be mainly used for as reinforcing material and resin, metal, ceramics and
Charcoal etc. is compound, manufactures advanced composite material.Carbon fibe reinforced epoxy composite material, specific strength and specific modulus are in existing work
Be in journey material it is highest, by Carbon fibe be applied to elevator balanced compensated chain production in be greatly improved elevator balanced compensated chain
Safe application performance.
Existing elevator balanced compensated chain chain in use because being flexibly connected between each lock ring, in elevator
Certain friction can be generated in balanced compensated chain high speed movement, the abrasion that prolonged friction is easy to cause lock ring to cover, especially
It is some frigolabile lock ring sets, when meeting extremely cold weather, is easy cracking, after cracking between exposed lock ring directly mutually
Friction is most likely to produce spark, and slight spark will cause fire when serious, and there are huge security risks.
