Abstract

The utility model discloses a plastic wrapping ring chain which comprises an iron chain (1), a plastic wrapping layer (2) and a filling body (3); wherein the plastic wrapping layer (2) is uniformly wrapped on the surface of the iron chain (1), and the filling body (3) is arranged in the chain ring of the iron chain (1) and connected with the plastic wrapping layer (2). The plastic wrapping ring chain has the advantages of the large load bearing capacity, the good wearing and tearing resistance, greatly reducing the operating noise of the elevator and having the long service life.

Description

Plastic Wrapped Chain

Technical field

The utility model relates to a kind of chain that is used for transmission, specifically, relates to a kind of tow chain that is used for balance and compensation elevator traction steel-cable and trailing cable.It is widely used in balanced compensated chain in the elevator and highway, bridge, tourist attractions guardrail.

Background technique

Be used for the balanced compensated chain on the elevator at present: the one, wear coir rope or wire rope reduces noise by the metal chain link, this compensation chain is easily distortion in running, and noise is big, poor safety performance, and easily get rusty; The 2nd, at metal light chain overcoat one deck plastic wrapper, though can slow down the bump of chain interannular, sheath is often easy to crack, and working life is short; The 3rd, at metal chain outer wrapping plastics, outer image round cable, this chain cost of production height; The 4th, on metal chain, be stained with one deck plastics, easily be subjected to displacement between the chain link and violent distortion, and the loop chain chain smashs the non-filler material, it is soaked mould layer wear-resisting property and the anti-poor performance of tearing, easy to crack.Chain at highway, bridge, tourist attractions protective grating: the one, metal light chain, even handle by electrogalvanizing, but the time is slightly long, is exposed in the air, just can get rusty in about about 1 year, and the color dullness is not attractive in appearance; The 2nd, adopt painting on metal chain, then need often to refresh, operate loaded down with trivial details.

Summary of the invention

The utility model provides a kind of Plastic Wrapped Chain rational in infrastructure at the existing technical problem of existing balanced compensated chain.Its bearing load is big, has good wear resistance, tearing property, reduces the elevator running noises significantly, and greatly enhance working life.

The utility model is for solving the problems of the technologies described above, be to realize by following technological scheme, described Plastic Wrapped Chain comprises iron chains, wraps up in and mould layer, wrap up in and mould layer and wrap surface equably at iron chains, the profile that keeps iron chains, difference is: it also comprises obturator, and obturator places in the above-mentioned iron chains chain link, obturator with above-mentioned wrap up in mould the layer link to each other.

Above-mentioned obturator is equipped with the outwards outstanding raised line parallel with iron chains chain link center line.

Above-mentioned wrapping up in moulded layer for PVC rubber-plastic or plastics, wraps up in that to mould layer thickness be 1.2-2.2mm.

Above-mentioned obturator is PVC rubber-plastic or plastics.

Above-mentioned wrap up in mould layer, the obturator surface is equipped with fluorescent layer.

Above-mentioned wrap up in mould layer, obturator contains phosphor, constitutes phosphor.

Of the present utility model wrapping up in moulded chain link and had following advantage compared with prior art:

1, the iron chains surface is equipped with to wrap up in and moulds layer, has good wear resistance, tearing property, and it can not only reduce the elevator running noises significantly, and iron chains is difficult for getting rusty, and increases the service life smooth surface, attractive in appearance greatly;

2, the iron chains chain link is built-in with obturator, makes iron chains chain interannular not produce displacement, further reduces the elevator running noises significantly.

3, iron chains wrap up in mould layer, the obturator surface is equipped with fluorescent layer, or wrapping up in of iron chains mould the alternate phosphor that contains in layer, the obturator, Plastic Wrapped Chain is during as guardrails such as highway, tourist attractions, night is more eye-catching, improves Safety performance.

4, the obturator of iron chains is equipped with outwards outstanding raised line and not only makes the iron chains chain link push not displacement, and can increase the withstand voltage and torsional buckling between the iron chains chain link, increases the service life.
