Abstract

The utility model discloses an elevator balancing compensation chain, which comprises an iron chain(1), a rubber pillar(2) and a fiber layer(3); wherein, the iron chain(1) is arranged inside the rubber pillar(2) which is enclosed with the fiber layer(3). The elevator balancing compensation chain adopts the iron chain(1) to eliminate rust. A rubber material is pressed into a mould to be enclosed with the iron chain(1) so as to form the rubber pillar(2). The rubber pillar(2) is arranged into the mould to press the rubber material into the mould to be enclosed with the surface of the rubber pillar(2) so as to form the fiber layer(3). After being vulcanized to fix the form by cooling, the utility model is formed after being polished and processed. When in operation, the elevator balancing compensation chain has the advantages of low noise, fine friction resistance, high breaking strength and breaking extension rate.

Description

Elevator balanced compensated chain

Technical field

The utility model relates to a kind of chain that is used for transmission, more particularly relates to a kind of tow chain that is used for balance and compensating elevator lifting.

Background technique

Elevator balanced compensated chain is used to connect the cab and the counterweight of elevator, is mainly used in the weight of balance hauling hope and trailing cable, and the operation of elevator is played balanced action, and it is big to require it to have a bearing load, and the operation noise is little, crooked characteristics such as flexible.At present, be used for the balanced compensated chain of elevator lifting: one is to use metal light chain, in the running of elevator, directly clashes into mutually between chain, and noise is big, easily gets rusty; The 2nd, metal light chain overcoat one deck plastic sheath, though can slow down the bump of chain interannular, this compensation chain plastic sheath is easy to crack, come off, working life is short; The 3rd, add at metal light interchain and to wear the rope made of hemp or wire rope, this compensation chain is easily distortion in running, and noise is big, and poor safety performance can only be applicable to the slower elevators below 1.75 meter per second to 2.5 meter per seconds.The balanced compensated chain that some are used for elevator lifting appears again recently.For example; the Chinese utility model patent specification of the CN2295870Y that on October 28th, 1998 was announced discloses a kind of like this elevator lifting balanced compensated " Plastic coated steel chain " that is used for; it is body with the iron chains; surface at each ring of iron chains adds the firm plastic protective layer of last layer; each chain ring surface of this compensation chain coats one deck and soaks and moulds layer, soaks to mould layer and be the PVC plastics.Each chain link is in contact with one another a little or face is to soak the surface of moulding layer, the noise when it can reduce the elevator operation.Yet, during this compensation chain traction cab, bearing load is big, each chain link is during through the slide-bar of peak, and chain link changes moving direction, is subjected to displacement between the chain link and violent distortion, it soaks moulds layer wear-resisting property and the anti-poor performance of tearing, easily wearing and tearing or cracking make to soak and mould layer and come off from the iron chains surface, and working life is short.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the shortcoming that exists in the prior art, a kind of elevator balanced compensated chain is provided, and its bearing load is big, has good wear resistance, resistance to tearing, when operation, can reduce elevator running noises, long service life effectively.

For solving the problems of the technologies described above, the utility model realizes that by following technological scheme described elevator balanced compensated chain comprises iron chains, rubber cylinder, layer of fibers, and above-mentioned iron chains places in the above-mentioned rubber cylinder, and above-mentioned rubber cylinder is wrapped with layer of fibers.

Above-mentioned layer of fibers is made of short fibre and rubber or plastics or rubber and plastic, and above-mentioned short fibre is uniformly distributed in the matrix of above-mentioned rubber or plastics or rubber and plastic, and fiber layer thickness is 0.5～3.5mm.

Above-mentioned layer of fibers is made of fibre cloth and rubber or plastics or rubber and plastic, and above-mentioned rubber or plastics or rubber and plastic evenly are coated on the above-mentioned fibre cloth, make through calendering, and fiber layer thickness is 0.5～3.5mm.

Elevator balanced compensated chain of the present utility model is compared with present technology and is had following advantage:

1, the iron chains of this elevator balanced compensated chain places in the rubber cylinder, and rubber cylinder is wrapped with layer of fibers, its smooth surface, and iron chains is difficult for getting rusty, and noise significantly reduces during the elevator operation;

2, this elevator balanced compensated chain is wrapped with the gluing layer of fibers, and interior is rubber cylinder, its intensity height, and wear resistance is good, and tear fracture intensity and tear fracture elongation percentage height, surface are not easy to crack, and bearing load is big, and Safety performance is improved, and bending is freely during operation.

3, this elevator balanced compensated chain is installed bending diameter less than existing product, is convenient to install, and can dwindle the pit erection space, saves and makes installation cost.

4, this elevator balanced compensated chain has the said structure characteristic, and also going for terraced speed is the above express elevators of 4 meter per seconds.
