Abstract

The invention discloses an anti-wear slag conveying chain. The chain comprises two parallel chain plate groups, wherein each chain plate group is formed by connecting a plurality of chain plates; pin shafts, sleeves and baffle rings are arranged between the chain plate groups; the sleeves are arranged on the outer sides of the pin shafts and enclose the pin shafts; first clearances are reserved between the sleeves and the pin shafts; third clearances are reserved between the chain plates and the sleeves; grooves are formed in the inner rings of the sleeves and are positioned between the sleeves and the third clearances; the baffle rings are positioned between the grooves and the pin shafts; and second clearances are reserved between the baffle rings and the sleeves. The inclined baffle rings are added between the sleeves and the pin shafts to prevent a material from entering the places between the sleeves and the pin shafts from the clearances of the chain plates, so that the pin shafts and the sleeves are prevented from being worn, the service lives of the chain plates, the pin shafts and the sleeves are prolonged, accordingly, the service life of the conveying chain is prolonged and can be up to over three years, and the cost for maintaining and replacing the conveying chain is reduced.

Description

A kind of anti-wear slag carrier chain

[technical field]

[background technology]

Elevator is the heavy mechanical equipment being undertaken transporting by changing potential energy, mainly contain bucket elevator, bucket elevator is a kind of plant equipment of fixture, be applicable to powdery, the continuous and perpendicular lifting of graininess and piece material, the driving component of bucket elevator has loop chain, plate chain, adhesive tape etc., plate chain structure is more firm, conduct oneself with dignity lighter, the carrier chain of palette chain easily weares and teares, chain bucket type hoist is promoting as slag, during the material of the abrasion severities such as flyash, the powdery of abrasion severity is in operation and enters between bearing pin and sleeve and between sleeve and roller, the part bearing pin of carrier chain and sleeve hole is caused to wear and tear quite serious, therefore have impact on the service life of elevator, general service life is 1 ~ 1.5 year, and cost of use is very high.

[summary of the invention]

Object of the present invention solves the problems of the prior art exactly, a kind of anti-wear slag carrier chain is proposed, the wearing and tearing between the part bearing pin of carrier chain and sleeve hole can be reduced, extend the service life of elevator, the expense reducing maintenance and change needed for chain and chain-plate.

For achieving the above object, the present invention proposes a kind of anti-wear slag carrier chain, comprise the carrier bar group that two row are parallel to each other, often organize carrier bar group to be formed by connecting by some carrier bars, between described carrier bar group, bearing pin is installed, sleeve and back-up ring, described sleeve is installed on the outside of bearing pin and is surrounded by bearing pin, the first space is left between described sleeve and bearing pin, the 3rd space is left between described carrier bar and sleeve, the inner ring of described sleeve has groove, described groove is between sleeve and the 3rd space, described shield ring sleeve is located on bearing pin, described back-up ring is positioned at groove, the second gap is left between described back-up ring and sleeve, described back-up ring is separate thrust collar.

As preferably, the cross section of described separate thrust collar is right angled triangle, and wherein a right-angle side and bearing pin are fitted and installed, and another right-angle side is between groove walls and bearing pin.

As preferably, the interior end points of the hypotenuse of described right angled triangle and carrier bar are fitted fixing, the outer end points of the hypotenuse of described right angled triangle and the inwall of groove fixedly mount, described separate thrust collar and the bearing pin right-angle side length of installing of fitting is 3.15 ~ 3.65mm, can fit tightly with sleeve, prevent material from falling between sleeve and bearing pin.

As preferably, the width in described first space is 0.1 ~ 0.3mm, stays activity space, facilitate chain operation between bearing pin and sleeve.

As preferably, the width in described second gap is 1 ~ 1.5mm, and the width in described 3rd space is 1 ~ 1.5mm, guarantees that bearing pin and quill are to retaining certain displacement space.

As preferably, the width in described second gap is 1.25mm, and the width in described 3rd space is 1.25mm.

Beneficial effect of the present invention: the present invention by adding a separate thrust collar between sleeve and bearing pin, material powder is stoped to enter between sleeve and bearing pin by the gap of carrier bar, and then avoid bearing pin and sleeve hole to wear and tear, and then extend the service life of carrier bar, bearing pin and sleeve, thus extend the service life of carrier chain, the service life of this product can reach more than 3 years, and reduces maintenance, the expense of replacing needed for carrier chain.

Feature of the present invention and advantage will be described in detail by reference to the accompanying drawings by embodiment.
