Abstract
The utility model proposes a kind of conveyor chains, including carrier bar, intermediate link, sleeve and pin shaft, the carrier bar and the central links are the continuous circular shape winding arrangement in chain direction, the intermediate link is arranged between the carrier bar of front and back, it is connected between the intermediate link and the carrier bar by pin shaft, the sleeve is set in outside the pin shaft, the inner wall of the sleeve is in convex, the convex portion of convex inner wall is successively decreased from the centre of casing to both sides, the length of the convex portion is the 1/3 to 1/2 of described sleeve pipe length, the convex portion is additionally provided with wearing layer, still there is chain harrow above the intermediate link.The conveyor chain wear-resisting property is high, and stability is good, long service life.
Description
Technical field
The invention belongs to chain technical fields, and in particular to a kind of conveyor chain.
Background technique
Currently, what conveyor chain used in production was all made of chain link one by one, during the work time, chain is frequent
It will receive the traction of equipment, to be broken, or the phenomenon that loosening, the quality of chain link directly affects the service life of chain
And safety, to cause very big security risk to production.Due to being substantially improved for the bucket conveyor speed of service, to chain
Wear-resisting property put forward new requirements, originally with the chain that 1 year can be used on common conveyer, be used in high speed and convey
3-6 months requirements can only be met on machine.This greatly limits the development of China's bucket conveyor cause.
Summary of the invention
The utility model proposes a kind of conveyor chains, and the conveyor chain wear-resisting property is high, and stability is good, service life
It is long.
The technical solution of the utility model is achieved in that
A kind of conveyor chain, including carrier bar, intermediate link, sleeve and pin shaft, the carrier bar and the central links are chain
The continuous circular shape winding arrangement in direction, the intermediate link are arranged between the carrier bar of front and back, the intermediate link and institute
It states and is connected between carrier bar by pin shaft, the sleeve is set in outside the pin shaft, and the inner wall of the sleeve is in convex, in convex
The convex portion of wall is successively decreased from the centre of casing to both sides, and the length of the convex portion is the 1/3 to 1/ of described sleeve pipe length
2, the convex portion is additionally provided with wearing layer, still has chain harrow above the intermediate link.
Preferably, the both ends of the carrier bar are arc-shaped.
Preferably, the junction of the sleeve and the carrier bar is equipped with limiting device.
Preferably, the wearing layer includes wear-resisting steel plate and self-lubricating bisque, and the self-lubricating bisque connects with the pin shaft
Touching.
The utility model has the beneficial effects that
Male projection is arranged by the inner wall in sleeve in the conveyor chain of the utility model, and the length of convex portion is described
The 1/3 to 1/2 of casing length can reduce a possibility that chain is broken as caused by imbalance in use in this way；Separately
Outside, convex portion is additionally provided with wearing layer and increases the wear-resisting service life of chain.Still there is chain harrow to play reinforcing above intermediate link
Stable effect extends the service life of chain, reduces production cost, improves security reliability.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig.1, a kind of conveyor chain, including carrier bar 1, intermediate link 2, sleeve 3 and pin shaft 4, the both ends of carrier bar 1 are circle
Arcuation.Carrier bar 1 and central links are the continuous circular shape winding arrangement in chain direction, the setting of intermediate link 2 front and back carrier bar 1 it
Between, it being connected between intermediate link 2 and carrier bar 1 by pin shaft 4, sleeve 3 is set in outside pin shaft 4, and the inner wall of sleeve 3 is in convex,
The convex portion 5 of convex inner wall is successively decreased from the centre of casing to both sides, and the length of convex portion 5 is the 1/3 to 1/ of casing length
2, convex portion 5 is additionally provided with wearing layer, and intermediate link 2 still has chain harrow 9 above.The junction of sleeve 3 and carrier bar 1 is equipped with limit
Device 6.Wearing layer includes wear-resisting steel plate 7 and self-lubricating bisque 8, and self-lubricating bisque 8 is contacted with pin shaft 4.
Male projection is arranged by the inner wall in sleeve 3 in the conveyor chain of the utility model, and the length of convex portion 5 is institute
State casing length 1/3 to 1/2 can reduce a possibility that chain is broken as caused by imbalance in use in this way；
In addition, convex portion 5, which is additionally provided with wearing layer, increases the wear-resisting service life of chain.Intermediate link 2 still has chain harrow 9 to play above
Stable effect is reinforced, the service life of chain is extended, reduces production cost, improve security reliability.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
